                                  THE COMPANY
 
  The Company is engaged in the development, ownership, operation, acquisition
and financing of power generation facilities and the sale of electricity and
steam in the United States. The Company currently has interests in four power
plants having an aggregate nameplate capacity of 1,382 megawatts. In 1997,
these plants produced an aggregate 8,662,000 megawatt hours of electricity and
7,665 million pounds of steam.
   
  The Company's principal assets consist of its substantial economic interests
in a 715 megawatt capacity Linden, New Jersey, cogeneration plant (the "Linden
Plant"), which sells its electric output to The Consolidated Edison Company of
New York, Inc. ("Con Ed") under a contract having an initial term expiring in
2017, a 176 megawatt capacity Bayonne, New Jersey, cogeneration plant (the
"Bayonne Plant"), which sells its electric output to Jersey Central Power &
Light Company ("JCP&L") and Public Service Electric and Gas Company of New
Jersey ("PSE&G"), under contracts having initial terms expiring in 2008 and a
146 megawatt capacity Camden, New Jersey, cogeneration plant (the "Camden
Plant"), which sells its electric output to PSE&G under a contract having an
initial term expiring in 2013. The Company has operating and maintenance
responsibility for the three principal plants and has contracted for the day-
to-day operation and maintenance of the plants with General Electric Company
("GE"). In addition, the Company has an equity investment in a 345 megawatt
capacity Bethlehem, New York cogeneration plant (the "Selkirk Plant"), which is
not economically material to the Company.     
 
INDUSTRY
   
  The Company is a participant in the highly competitive power generation
industry, which is among the largest industries in the United States, with an
estimated end-user market of over $200.0 billion of electricity sales and
annual net generation of approximately 3.5 million gigawatt hours. New
regulatory initiatives have been or currently are being adopted or considered
at the federal level and in approximately 45 states to increase competition in
the domestic power generation industry. In April 1996, the Federal Energy
Regulatory Commission ("FERC") adopted Order No. 888, opening wholesale power
sales to competition and providing for open and fair electric transmission
services by public utilities. At the state level, industry restructuring is
well advanced in various states including California, Massachusetts, New York,
New Jersey and Pennsylvania. This restructuring includes deregulation of
electric utilities and the introduction of customer choice. The regulatory
initiatives are expected to lead to the transformation of the existing market,
which is largely characterized by electric utility monopolies, having old,
inefficient, high-cost generating facilities, selling to a captive customer
base, to a more competitive market where end users may purchase electricity
from a variety of suppliers, including non-utility generators, power marketers,
public utilities and others.     
 
  The Company believes that these market trends will present substantial
opportunities for industry participants that are efficient and low-cost power
producers and are able to offer competitive rates to customers. The Company
believes that an additional opportunity is presented by the significant
deregulation and consolidation now affecting the power industry, which has
resulted in substantial divestitures of generation assets by traditional power
utilities and by certain independent power producers currently owning
relatively few plants. For example, as a result of regulatory initiatives,
approximately 14,000 megawatts of New York generating capacity has been
announced for sale by utilities. Similar regulatory initiatives in New Jersey
and Pennsylvania are expected to cause utilities in those states to pursue
similar divestiture plans. At the same time, a number of industrial companies
have also announced plans to sell self-generation facilities and to re-deploy
the capital in their core businesses. These trends, which the Company believes
are likely to continue, should provide significant acquisition opportunities
for the Company.
 
  The Company also believes that attractive opportunities for development of
new generation assets will arise in the next few years, principally due to a
projected increase in baseload demand in the Northeast and Mid-Atlantic regions
and the retirement of a significant number of existing power generation
facilities which are 30 or more years old.

STRATEGY
 
  The Company's strategy is to maximize cash flow associated with its existing
power plants and to grow through expansion of the Company's existing operations
and through the acquisition and development of existing or new power generation
and related facilities. Specific aspects of this strategy are set-forth below:
 
 .  Maximize the Value of Existing Assets. The Company's high quality plant and
   equipment and long duration power sales agreements have provided it with
   stable long-term cash flow. In order to maintain the quality of these
   assets, and to further increase margins, the Company's core strategy
   includes continuous capital investment in current facilities to assure
   ongoing efficiency consistent with high rates of return on capital. In
   keeping with these objectives, the Company has systematically pursued
   technological upgrades and retrofits to existing plants which increase
   output or operating efficiency. As an example, the capacity of each of the
   nine gas turbines at the Linden, Camden and Bayonne Plants has been
   increased by approximately 2.5 megawatts per gas turbine. At the Camden
   Plant, an inlet chiller system recently was installed which increases the
   generation capacity of the plant by 32,000 megawatt hours per year. In
   addition to these improvements, the Company currently is considering a
   number of technology investments, some of which, if implemented, the Company
   expects will (i) reduce fuel costs at the Bayonne Plant, (ii) reduce water
   usage and associated expenses at the Camden Plant, (iii) generate additional
   steam sales and electrical output through modest expansion and the addition
   of equipment at the Camden Plant, (iv) reduce water costs at the Linden
   Plant and (v) increase electrical output through the use of chilled water
   equipment improvements at the Linden Plant. The Company will continue to
   seek to add value to its existing projects and its customers through
   mutually negotiated contractual and operating changes such as those changes
   successfully negotiated to Linden Venture's power purchase agreement with
   Con Ed in September 1990 and December 1993. The Company will continue to
   monitor, revise and replace its fuel supply arrangements to obtain a balance
   between immediate savings in gas and transportation costs and the need to
   maintain regular and secure relationships with various gas producers and
   transporters of gas.
 
 .  Expand Existing Plants. The Company believes that all three of the plants in
   which it has a substantial economic interest are capable of being expanded
   not only through additions to existing plants but also through the
   development and construction of new power plant facilities at the existing
   sites. In this regard, the Company has permit applications pending and
   presently is engaged in advanced strategic design work with respect to the
   addition of a new 250 megawatt unit at the Linden Plant with a view to
   utilizing such plant's direct interconnect with Con Ed in New York City.
   With respect to the Bayonne Plant, the Company is considering the
   installation of a new power facility at that location.
 
 .  Pursue Domestic Electricity Generation Acquisitions and Other Opportunities.
   The Company believes that it will have ample opportunities to grow its
   operations through acquisitions, development of new assets and through other
   means, whether on its own or through partnerships with companies that have
   complementary skills. This strategy is based on the Company's view that
   baseload demand for power will increase over the next few years, and that
   retirement of a significant number of existing plants will further spur the
   need for additional capacity. In addition, a number of utilities in the
   Northeastern United States have announced plans to divest power generating
   assets, including Con Ed, General Public Utilities, New York State Electric
   and Gas, and Niagara Mohawk Power Company. This development, together with
   expected further consolidation in the independent power industry, may offer
   the Company a number of opportunities to grow its business by making
   strategically significant acquisitions, with an initial focus in the
   Northeast. Longer term, the Company intends to continue to consider
   opportunities for new developments of power generation facilities in the
   Northeast and elsewhere in the United States. The Company has no plans for
   expansion into the international arena.

  The Company believes that the following competitive strengths will aid in the
successful implementation of its strategy:
 
 .  Efficient and Reliable Power Projects. The Company's three principal plants
   have well-established and consistent records of service to their customers.
   The average availability for all of these plants has exceeded 92% since
   placed in operation. This record of service is principally the result of the
   highly reliable combined-cycle technology, which generally is significantly
   more efficient than that of a majority of the existing utility generating
   facilities in the region, together with the operations and maintenance
   practices of the Company.
 
 .  Favorable Contracts and Stable Cash Flow. The utility power purchase
   contracts relating to the Company's three principal plants have long-term
   remaining lives, with expirations ranging from 2008 to 2017. For example,
   the Linden Plant has nameplate electric capacity of 715 megawatts and
   represents approximately 70% of the Company's power generating assets.
   Linden Venture has a power purchase agreement which expires in the year
   2017. In addition, all of the Company's existing power purchase agreements
   are with large utilities which presently have investment grade senior debt
   ratings. The Company's principal power plants historically have provided a
   consistent and substantial cash flow to equity holders due to the fixed
   payment components of the power purchase contracts which have provided
   favorable margins over the ventures' fixed operating and financing costs.
   Moreover, the variable energy payment components of such agreements, which
   provide the second major component of pricing under such agreements, have
   historically been well correlated to fuel costs at the Bayonne and Camden
   Plants and have reflected a partial pass-through mechanism for fuel expenses
   at the Linden Plant.
 
 .  Environmental Considerations. The Company's existing plants principally burn
   natural gas, which is a clean burning fuel, and they employ advanced
   environmental technology which makes them among the cleanest in the
   industry. The existing plants also are operated in compliance with
   applicable state and federal environmental regulations.
 
 .  Regional Expertise in Northeast Power Markets. As a result of the location
   of its existing assets and its active involvement in industry restructuring,
   the Company has developed significant expertise in Northeastern power
   markets. This expertise could provide the Company with a competitive
   advantage in pursuing additional opportunities within the region.
   
 .  Experienced Management. The Company's senior management team, led by the
   founder of the Company's predecessor companies, Robert C. McNair, has an
   aggregate of over 117 years of experience in the energy industry. The
   Company currently operates plant and equipment that is widely viewed to be
   among the safest and most environmentally advanced in the industry. The
   Company's philosophy is to maintain a small, well-qualified management team
   with expertise in all aspects of the independent power business, to actively
   participate in a broad range of regulatory affairs governing the industry
   and to retain additional experts in connection with the construction,
   maintenance and operation of its plants.     
 
 .  Strong Financial Position. The Company believes that its high quality
   assets, its federal income tax position and its long duration power supply
   contracts provide it with the financial strength to access the capital
   markets to obtain the capital needed to fund execution of its strategic
   plan.

FORMATION
 
  Cogen was incorporated in May 1998 at the instance of Robert C. McNair to
acquire operating control of three entities operating independent power plants
in New Jersey, together with an indirect equity interest in a fourth plant
operating in New York. Prior to the consummation of the Formation Transactions,
the Cogen ownership interests in the plants were 82% beneficially owned by Mr.
McNair and members of his family, and by entities controlled by his family (the
"McNair Interests"). The remaining 18% of such interests was beneficially held
by other persons or entities (the "Minority Interests") with no relation to the
McNair Interests. Upon consummation of the Formation Transactions, Cogen will
own the interests in the subsidiaries held by the McNair Interests and the
Minority Interests. See "Certain Transactions--Formation Transactions". The
following chart sets forth, in a simplified manner, the organizational
structure of the Company with respect to its interests in the ventures owning
the plants immediately following the consummation of the Formation
Transactions, eliminating certain intermediate entities that may be formed to
hold various interests.

    Formation Transactions.     
 
DIVIDEND POLICY
 
  Cogen plans to pay dividends on the Common Stock of approximately $    per
share per quarter. During the initial years of the Company's operations,
dividends with respect to the Common Stock are expected to exceed the share of
the current and accumulated earnings and profits of the Company allocable to
the holders of the Common Stock (as determined for United States federal income
tax purposes). In such a case, such excess generally would be treated as a tax-
free return of capital up to a holder's basis in such holder's shares of Common
Stock and as capital gain thereafter. See "Dividend Policy".
 
  The Company's principal executive office is located at 711 Louisiana, 33rd
Floor, Houston, Texas 77002, and its telephone number is 713/336-7700.

    Offering, the Debt Offering and the application of the proceeds thereof as
    if such transactions had occurred on January 1, 1997 with respect to the
    income statement data and June 30, 1998 with respect to the balance sheet
    data.     
(2) In 1994 Cogen Technologies Capital Company, L.P. began charging Linden Ltd.
    and Camden GPLP for overhead costs that benefit the revenue producing
    activities of such entities. Such overhead charges were not charged to
    Linden Ltd. and Camden GPLP prior to 1994.
(3) Relates to payment made by Camden GPLP to another company under the terms
    of an agreement which provided, among other things, that the other company
    and its affiliates would not, in consideration for such payment, own or
    acquire an interest in any facility producing electricity or thermal
    energy for sale in Camden, New Jersey through December 31, 1993.
   
(4) Camden Inc. is an S corporation and Linden Ltd. and Selkirk LP are
    partnerships, and income taxes are recognized by the individual partners or
    shareholders (with the exception of New Jersey state income taxes which are
    recognized by Camden Inc.). Accordingly, such income taxes are not
    recognized in the combined financial statements. MESC and CT Global account
    for all income taxes and Camden Inc. accounts for New Jersey state income
    taxes in accordance with Statement of Financial Accounting Standards
    ("SFAS") No. 109, "Accounting for Income Taxes". Deferred tax assets and
    liabilities are recognized based on anticipated future tax consequences
    attributable to differences between the financial statement carrying
    amounts of assets and liabilities and their respective tax bases.     
   
(5) Reflects the effect of income taxes on the Group's historical results since
    the Company will be a taxable entity. Income taxes with respect to certain
    entities are not recognized in the historical financial statements (see
    Note 4 to this table). Following the consummation of the Formation
    Transactions the Company will be the partner or shareholder of such
    entities and such income taxes will be recognized in its financial
    statements.     
   
(6) Funds from operations ("FFO"), as presented herein, is defined as net

    amortization. FFO should not be considered in isolation or as a substitute
    for net income, cash flow provided by operating activities or other income
    or cash flow data prepared in accordance with generally accepted
    accounting principles or as a measure of a company's profitability or
    liquidity. FFO, as presented herein, may not be comparable to similarly
    titled measures reported by other companies. FFO data is presented because
    the Company believes that FFO is a measure of operating performance that
    is used by credit rating agencies, analysts and investors because it
    provides useful supplemental information to GAAP information as to the
    Company's ability to service its indebtedness.

                                 RISK FACTORS
 
  An investment in the Common Stock involves a significant degree of risk.
Prospective purchasers should consider carefully the factors and cautionary
statements set forth below, as well as the other information provided
elsewhere in this Prospectus, before making an investment in the Common Stock.
 
  When used in this Prospectus, the words "anticipate", "estimate", "expect",
"project" and similar expressions are intended to identify forward-looking
statements. Such statements are subject to certain risks, uncertainties and
assumptions. Should one or more of these risks or uncertainties materialize,
or should underlying assumptions prove incorrect, actual results may vary
materially from those anticipated, expected or projected. Among the key
factors that have a direct bearing on the Company's results of operations and
the industry in which it operates are the Company's reliance on, or revenues
from, third parties, the effects of various governmental regulations, the
fluctuation in fuel and operating costs and the costs and effectiveness of the
Company's strategy. These and other factors are discussed below and elsewhere
in this Prospectus.
 
ABSENCE OF COMBINED OPERATING HISTORY
 
  Cogen was incorporated in Delaware in May 1998 at the instance of Robert C.
McNair to be a holding company and has conducted no operations to date other
than in connection with the Offerings and the Formation Transactions, which
involve the acquisition and combination under a single holding company of
substantial equity interests in three independent power project ventures and
an equity investment in a fourth venture. The success of the Company will
depend, in part, on the extent to which it is able to combine effectively
expanded and newly-acquired operations with its existing operations. No
assurance can be given that the Company's management will be able to fully
integrate newly-acquired operations, including by centralizing accounting and
administrative systems and eliminating other unnecessary duplication, or
otherwise manage effectively any additional businesses it may acquire, or even
to implement the Company's acquisition strategy. Because the operations of the
Company are conducted primarily by the subsidiaries and ultimately by the
ventures in which the subsidiaries have interests, Cogen's cash flow and its
ability to service indebtedness, including its ability to pay the interest on
and principal of the Senior Notes and to pay dividends on the Common Stock,
depend entirely upon the earnings of the ventures and the subsidiaries and the
distribution of those earnings to the Company. Cogen currently has no business
other than its ownership interests in the subsidiaries and its planned
development and acquisition business.
 
RISKS RELATED TO HOLDING COMPANY STRUCTURE
 
Risks on Ventures' Ability to Make Distributions to the Company
 
  Each of the existing ventures in which the Company has an interest (other
than the Linden Venture) has been financed through, and the future ventures in
which the Company may acquire an interest may be financed through, non-
recourse project finance arrangements. These types of arrangements generally
require that the venture pledge as collateral to the venture lenders the
venture's cash flow, accounts and all other tangible and intangible assets of
the venture, and that the venture's owners pledge to the venture lenders the
partnership interests or other equity in the venture. Further, the debt
agreements to which the existing ventures are parties contain provisions
generally restricting the ability of the ventures to pay dividends, make
distributions or otherwise transfer funds to their owners, including the
Company, and contain restrictions on the ability of the ventures to, among
other things, incur debt, alter the plants or amend third party contracts. The
restrictions in such agreements generally require that, prior to the payment
of dividends, distributions or other transfers, the venture proposing to make
the payment must provide for the payment of other obligations, including
operating expenses (which include fuel payments), debt service and reserves.
The Company anticipates that future ventures would have similar restrictions.
A default under such debt agreements as to such restrictions or any other
covenants in the debt agreements could give the venture lenders the right to
accelerate the repayment of the debt and foreclose on the collateral securing
the debt, including the operating assets of a venture.

Rights of the Company to Assets or Cash Flow of Subsidiaries or Ventures
Subordinate to Creditors of Such Subsidiaries or Ventures
   
  The Company's subsidiaries and ventures in which they have interests are,
and in the future are expected to be, separate and distinct legal entities
that will have no obligation, contingent or otherwise, to pay any amounts due
on the Senior Notes or in respect of dividends on the Common Stock or to make
funds available therefor, whether by dividends, loans or other payments, and
none of such subsidiaries and ventures are expected to guarantee the payment
of interest on or principal of the Senior Notes. Any right that the Company
has to receive any assets of any of its subsidiaries or ventures in which they
participate upon any casualty of the plants or liquidation, bankruptcy or
reorganization thereof, and the consequent right of the holders of the Common
Stock or Senior Notes to participate in the distribution of, or to realize
proceeds from, those assets, effectively will be subordinated to the claims of
such subsidiaries' and ventures' creditors (including holders of debt issued
by such subsidiaries or ventures or secured by their assets or cash flows and
trade creditors and other general unsecured creditors). After giving effect to
the transactions contemplated by the Offerings on a pro forma basis as of June
30, 1998, $382.0 million of indebtedness of certain of the Company's
subsidiaries and ventures (exclusive of indebtedness of Selkirk Venture in
which the Company has a passive equity investment) would be effectively senior
to the Senior Notes, and, of course, would be senior to the rights of holders
of the Common Stock. In addition to the foregoing indebtedness, Linden Venture
and Camden Cogen are structured such that holders of certain preferred equity
interests therein have a claim to such ventures' distributable cash that must
be satisfied before any remaining distributable cash may be distributed to the
Company's subsidiaries. These claims are, therefore, likewise effectively
senior to the claims of the holders of the Company's indebtedness and the
rights of the holders of the Common Stock. The nature of the preferred equity
interests' claim to the distributable cash of Linden Venture and Camden Cogen
is a function of the special allocation provisions of the partnership
agreements that relate to such ventures. The allocations of the cash flows
from the ventures, which significantly affect the cash flow distributed to the
Company's subsidiaries, are described separately with respect to each venture
elsewhere in this Prospectus. See "Existing Venture and Plant Descriptions--
Linden Cash Distributions" on pages 55 through 56, "Existing Venture and Plant
Descriptions--Camden Cash Distributions" on pages 70 through 71 and
"Description of Senior Notes and Certain Other Indebtedness--Plant Project
Financing" on pages 103 through 106. The indenture, as initially supplemented
by a first supplemental indenture thereto, relating to the Senior Notes (the
"Indenture") will impose limitations on the ability of the Company, its
subsidiaries and the ventures to incur additional indebtedness. See "--
Substantial Leverage" and "Description of Senior Notes and Certain Other
Indebtedness--Description of Senior Notes".     
   
HIGHLY COMPETITIVE INDUSTRY     
 
  The power generation industry is characterized by numerous strong and
capable competitors, including utilities, industrial companies and other power
producers. Many of these competitors have extensive and diversified
developmental or operating experience and financial resources equal to or
greater than those of the Company. Further, in recent years the power
production industry has been characterized by strong and increasing
competition with respect to both obtaining power sales agreements and
acquiring existing power generation assets. This competition has generally
resulted in reductions in prices paid for electricity, including reductions in
prices in new power sales agreements where available, and reduced operating
margins for merchant power plants which sell their power into the wholesale
market without long-term contracts. Similarly, such competition has caused
higher acquisition prices in some instances for existing assets through
competitive bidding practices. The evolution of competitive electricity
markets and the development of highly efficient gas-fired power plants have
also caused, or are anticipated to cause, downward price pressure in power
markets. Further, there is increasing competition among electric utilities
which, in response to state regulatory initiatives that are designed to give
all electric customers the ability to choose between competing suppliers of
electricity, effectively are being required to lower their costs, including
the cost of purchased electricity. Changes in law also could encourage greater
competition in electricity markets, which could result in both a decline in
the number of long-term power purchase contracts and in the rates paid by
electric utilities and other purchasers of electricity. Increasing competition
in the future likely will increase this pressure. Although purchase prices for
electricity under the power purchase agreements to which the Company's
ventures are party contain fixed price formulas, a decline in
 
                                      14
<PAGE>
 
long-term rates to be paid by electric utilities generally could indirectly
adversely affect the Company's profits in connection with any future merchant
sales to power purchasers (sales of power at market prices not pursuant to
long-term contracts). This competition has put pressure on electric utilities
to lower their costs, including the cost of purchased electricity, and
increasing competition in the future will increase this pressure. See "--Above
Market Power Purchase Agreements" and "--Risks Arising from Utility Regulation
and Deregulation". Because the Company's plants at present have long-term
power purchase agreements, the Company believes that the greatest immediate
risks of such competitive factors will relate to its ability to grow through
development or undertake acquisition of additional power generating businesses
which will provide attractive rates of return on invested capital.
 
SUBSTANTIAL LEVERAGE
   
  Upon the consummation of the Common Stock Offering, the Debt Offering and
the other transactions contemplated thereby, including the Formation
Transactions, the Company will have substantial indebtedness. At June 30,
1998, after giving pro forma effect to the Common Stock Offering, the Debt
Offering and the transactions contemplated thereby, including the Formation
Transactions, the Company would have had total indebtedness of approximately
$624.7 million or a ratio of debt to total capitalization of approximately one
to one. Such amount excludes indebtedness at the venture level of
approximately $157.7 million. See "--Risks Related to Holding Company
Structure--Rights of Company to Assets or Cash Flow of Subsidiaries or
Ventures Subordinate to Creditors of Such Subsidiaries or Ventures",
"Capitalization" and "Management's Discussion and Analysis of Financial
Condition and Results of Operations--Liquidity and Capital Resources". The
ability of the Company to meet its debt service obligations and to repay
outstanding indebtedness according to its terms will be dependent primarily
upon the performance of the power plants in which the Company's subsidiaries
have an interest.     
   
  The Indenture will contain certain restrictive covenants which initially
affect, and in many respects significantly limit or prohibit, (i) indebtedness
of the Company, other than (w) the Senior Notes, (x) up to $300.0 million at
any one time outstanding in senior secured bank indebtedness, (y) certain
other parity indebtedness (provided that the issuance of such parity
indebtedness would either be incurred in compliance with a coverage ratio
requirement or not result in a rating downgrade of the Senior Notes) and (z)
subordinated debt, (ii) additional indebtedness of the ventures (except
Selkirk Venture) in which the Company currently has an interest, other than up
to $100.0 million at any one time outstanding for plant improvements and
expansion and amounts required to satisfy any fiduciary responsibilities of
the partner or venturers of each of the ventures, and (iii) distributions to
stockholders or on account of subordinated indebtedness owed to affiliates
unless no default exists under the Indenture and such distributions do not
exceed 100% of Funds From Operations (as defined in the Indenture) (as of the
closing date of the issuance of the Senior Notes) plus $50.0 million. Each of
such restrictive covenants (together with mandatory redemption provisions,
certain events of default and, subject to a further condition, the security
interest below described) will be eliminated in the event (i) the Company owns
and is expected to continue to own equity interests in at least eight power
project ventures with no single venture contributing more than 25% or less
than 5% of the aggregate Cash Distributions (as defined in the Indenture) for
a period of time defined in the Indenture and (ii) the then current ratings of
the Senior Notes are at least investment grade by Moody's Investor Services,
Inc., Standard & Poor Rating Services and Duff & Phelps Credit Rating Co.,
respectively. There can be no assurance that the Company will be able to
satisfy the conditions precedent to the operation of such covenant-elimination
provisions. If the Company is unable to satisfy such conditions precedent, the
restrictive covenants in the Indenture may continue until the final maturity
of the Senior Notes. See "Description of Senior Notes and Certain Other
Indebtedness--Description of Senior Notes". For a description of restrictions
pursuant to the debt financing arrangements applicable to the various ventures
in which the Company has ownership interests, see "Description of Senior Notes
and Certain Other Indebtedness--Plant Project Financings". In addition, the
Senior Notes will be secured, on a pari passu basis, by a security interest
granted by Cogen in a portion of the equity interests of Cogen in certain of
its direct, wholly-owned subsidiaries, which subsidiaries own the equity
interests of Cogen in each of Linden Venture, Camden Cogen and NJ Venture. In
no event will such security encumber any such venture or the general partner
of any such venture, or any of their respective rights or properties. If the
Company were unable to meet its obligations under the Indenture, the trustee
under the Indenture would have the right to foreclose on such equity
interests.     
 
                                      15
<PAGE>
 
  The Company expects to secure a $300.0 million revolving credit facility
(the "Revolving Credit Facility") prior to the consummation of the Common
Stock Offering which, if obtained, likely will contain certain restrictions
that limit or prohibit, among other things, its ability to incur indebtedness,
repay certain indebtedness, pay dividends, make investments, create liens,
sell assets and engage in business combinations.
 
  If the Company is unable to comply with the terms of its debt agreements and
fails to generate sufficient cash flow from operations in the future, the
Company may be required to refinance all or a portion of its existing debt or
to obtain additional financing. There can be no assurance that any such
refinancing would be possible or that any additional financing could be
obtained, particularly in view of the Company's expected levels of debt and
the debt incurrence restrictions under existing debt agreements. If cash flow
is insufficient and no such refinancing or additional financing is available,
the Company may be forced to default on its debt obligations. In the event of
a default under the terms of any of the indebtedness of the Company, subject
to the terms of such indebtedness, the obligees thereunder would be permitted
to accelerate the maturity of such obligations, which could cause defaults
under other obligations of the Company, and foreclose all applicable liens,
including with respect to the liens on a portion of the Company's equity
interests in Linden Venture, Camden Cogen and NJ Venture. See "--Risks Related
to Holding Company Structure" and "Management's Discussion and Analysis of
Financial Condition and Results of Operations".
   
SPECIFIC OPERATING RISKS OF POWER GENERATION AND STEAM PRODUCTION FACILITIES
    
  The operation of power generation and steam production facilities involves
many risks, including the breakdown or failure of power generation equipment,
transmission lines, pipelines or other necessary equipment or processes and
performance below expected levels of output or efficiency. While the Company's
independent power plants (excluding the Selkirk Plant in which the Company is
an investor and does not have operating responsibility) historically have
operated at over 90% of then available capacity, these plants have from time
to time experienced certain equipment breakdowns or failures. The Company's
principal existing independent power plants are being operated pursuant to
separate operations and maintenance agreements between the respective ventures
and the same third party operator, GE. See "Existing Venture and Plant
Descriptions". Although as of the date of this Prospectus such breakdowns or
failures have not had a material adverse effect on the operation of such
plants or on the Company's results of operations, and although the Company's
existing plants contain certain redundancies and backup mechanisms, there can
be no assurance that any future breakdown or failure would not prevent the
affected plant from fully performing under its power or steam sales agreements
or being able to market electricity in sufficient quantities and at favorable
margins. Because the Company is unable to predict the exact nature of any
future possible breakdown or failure, it is unable to predict the impact
thereof.
 
  In addition, although insurance is maintained to protect against certain of
these operating risks, the proceeds of such insurance may not be adequate to
cover lost revenues or increased expenses. As a result, the venture owning the
plant may be unable to service principal and interest payments under its
financing obligations and may operate at a loss. Further, there can be no
assurance that the insurance currently maintained for the existing plants will
be available in the future for these or additional projects at commercially
reasonable costs or terms. Any such operating risks could lead to a default
under the venture's debt and other financing agreements, which could result in
the Company's losing its interest in the subject venture. In addition,
extended unavailability of capacity under any power purchase agreement or
steam sales agreement pursuant to which electricity or steam, as the case may
be, generated by the subject plant is sold, which could result from such
events, may entitle the purchaser thereunder to terminate the power purchase
agreement or steam sales agreement, as applicable.
 
PERMITTING RISKS
 
  The Company is required to comply with numerous federal, state and local
statutory and regulatory standards and to maintain numerous permits and
approvals required for the construction, ownership and operation of its
plants. See "Government Regulation". Some of the permits and regulatory
approvals that have been issued with respect to the Company's existing plants
contain certain conditions, and future permits and approvals also
 
                                      16
<PAGE>
 
are expected to contain conditions. Failure to satisfy any such conditions or
approvals could prevent or limit the construction or operation of a plant or
result in additional costs or lower revenues. There can be no assurance that
any plant will continue to operate in accordance with the conditions
established by the permits or approvals or be able to renew such permits and
approvals. Laws and regulations affecting the Company and its ventures and
other venture participants can be expected to change in the future, and such
changes could adversely affect the Company and its ventures and such other
venture participants. For example, changes in laws or regulations (including
but not limited to tax and environmental laws and regulations) could (i)
impose more stringent or comprehensive requirements on the operation or
maintenance of the Company's plants, resulting in increased compliance costs,
the need for additional capital expenditures or the reduction of certain
benefits currently available to the plants, or (ii) expose the Company and its
ventures to liabilities for actions taken prior to the formation of the
Company that were in compliance with laws in effect at the time or for actions
taken by or conditions caused by third parties. Although the ventures
operating the Company's principal plants have obtained and maintained all
material permits and approvals required for the ownership and operation of
their plants, there can be no assurance that the requirements contained in
such permits will not change or that the Company's ventures will be able to
renew or to maintain all permits and approvals required for continued
operation of their facilities. Failure to renew or to maintain any required
permit or the inability to satisfy any requirement of any permit may result in
limited or suspended operation of the affected plant. In addition, the
Company's plants generally are located on premises leased from steam hosts
and, therefore, the plants could be adversely affected by the permit
compliance of such steam hosts.
 
RISKS ARISING FROM UTILITY REGULATION AND DEREGULATION
 
  The generation, transmission and distribution of electricity in the United
States historically have been highly regulated both at the federal and state
levels. Even though there have been deregulatory initiatives at the federal
and state levels in recent years, the industry remains subject to significant
regulation in many respects. While the Company believes that its business is
operating in accordance with applicable laws, the Company remains subject to a
varied and complex body of laws and regulations that both public officials and
private individuals may seek to enforce. There can be no assurance that
existing laws and regulations will not be revised or that new laws and
regulations will not be adopted or become applicable to the Company that may
have a material adverse effect on the Company's business or results of
operations. Because the Company is unable to predict the exact nature of any
possible revision to existing or enactment of new laws, it is unable to
predict the impact thereof. See "Government Regulation".
 
  The Company's operations are subject to the provisions of various energy
laws and regulations, including the Public Utility Regulatory Policies Act of
1978, as amended, and implementing regulations ("PURPA"), the Public Utility
Holding Company Act of 1935, as amended ("PUHCA"), and state and local
regulations. See "Government Regulation--Federal Energy Regulation". PUHCA
provides for the extensive regulation of public utility holding companies and
their subsidiaries. PURPA provides to qualifying facilities ("QFs") (as
defined under PURPA) and owners of QFs exemptions from certain federal and
state regulations, including rate and financial regulations.
 
  Under present federal law, the Company is not subject to regulation as a
holding company under PUHCA, and will not be subject to such regulation as
long as the plants in which it has an interest qualify as QFs, are subject to
another exemption or waiver or qualify as an exempt wholesale generator
("EWG") under the Energy Policy Act of 1992. In order to be a QF, a facility
must be not more than 50% owned by an electric utility company or electric
utility holding company. In addition, a QF that is a cogeneration facility, as
are the plants in which the Company currently has interests, must produce not
only electricity, but also useful thermal energy for use in an industrial or
commercial process for heating and cooling applications in certain minimum
proportions to the QF's total energy output. The QF also must meet certain
minimum energy efficiency standards. Linden Venture currently sells the
majority of the Linden Plant's steam to Bayway Refining Company ("Bayway")
under an arrangement that is not evidenced by a written agreement. Although
Linden Venture and Bayway are negotiating the terms of a written steam sales
agreement, there can be no assurance that such agreement will be executed or,
in the event that it is executed, as to its terms. If Bayway were to cease
purchasing steam from
 
                                      17
<PAGE>
 
Linden Venture, the QF status of the Linden Plant would be in jeopardy. In
addition, the two steam sales agreements to which NJ Venture is a party renew
on a year-to-year basis, subject to termination by either party at the end of
any year. If the purchasers under these agreements were to terminate these
steam sales agreements, the QF status of the Bayonne Plant would be in
jeopardy. (For further information in this regard as to the status of the
Linden Plant's steam sales, see "Existing Ventures and Plant Descriptions--
Linden Steam Sales Agreement" and, as to the status of the Bayonne Plant's
steam sales, "Existing Venture and Plant Descriptions--Bayonne Agreement for
the Sale of Steam and Electricity to IMTT-Bayonne" and "Existing Venture and
Plant Descriptions--Bayonne Agreement for the Sale of Steam to IMTT-BX
(formerly Exxon)", respectively.) If any of the plants in which the Company
has an interest were to lose its QF status and not otherwise receive a Federal
Energy Regulatory Commission ("FERC") waiver, PUHCA exemption or qualify as an
EWG, or if amendments to PURPA were enacted that substantially reduced the
benefits currently afforded QFs, the subsidiary or venture in which the
Company has an interest could become a public utility company, which could
subject the Company to significant federal, state and local laws, including
rate regulation. This loss of QF status, which may be prospective or
retroactive, in turn, could cause all of the Company's other power plants to
lose QF status because, under FERC regulations, a QF cannot be owned by an
electric utility or electric utility holding company. In addition, a loss of
QF status could, depending on the particular power purchase agreement, allow
the power purchaser to cease taking and paying for electricity or to seek
refunds of past amounts paid and thus could cause the loss of some or all
contract revenues or otherwise impair the value of a project. See "Existing
Venture and Plant Descriptions--Linden Power Purchase Agreement" and "Existing
Venture and Plant Descriptions--Camden Power Purchase Agreement". If a power
purchaser were to cease taking and paying for electricity or seek to obtain
refunds of past amounts paid, there can be no assurance that the costs
incurred in connection with the project could be recovered through sales to
other purchasers. Such events could adversely affect the ability of the
Company and its ventures to service their indebtedness, including the Senior
Notes, and the ability of the Company to pay dividends on the Common Stock.
See "Government Regulation--Federal Energy Regulation".
 
  Currently, Congress is considering proposed legislation that would amend
PURPA by eliminating the requirement that utilities purchase electricity from
QFs at Avoided Costs. The effect of any such amendment cannot be predicted,
although any such amendment could have a material adverse effect on the
Company.
 
  FERC and many state utility commissions are currently studying a number of
proposals to restructure the electric utility industry in the United States.
Such restructuring could permit utility customers to choose their utility
generator supplier in a competitive electric energy market. FERC issued a
final rule in April 1996 which requires utilities to offer eligible wholesale
transmission customers non-discriminatory open access on utility transmission
lines on a comparable basis to the utilities' own use of the lines. The final
rule has been the subject of rehearing and now is undergoing judicial review.
To date, no states have avoided QF contracts, but it is possible that as part
of the restructuring, QF contracts could be voided. The effect of any such
restructuring cannot be predicted, although any such restructuring could have
a material adverse effect on the Company. As to recent proposals by the
Clinton Administration, see "Government Regulation--Federal Energy
Regulation--Proposed Deregulation".
   
SUBSTANTIAL ENVIRONMENTAL REQUIREMENTS AND COSTS OF COMPLIANCE     
 
  The Company's plants are and will be required to comply with a number of
federal, state and local statutes and regulations relating to protection of
the environment and to the safety and health of the public and of personnel
operating the plants. Such statutes and regulations, which are always subject
to change, include regulation of hazardous substances associated with each
plant, limitations on noise emissions from the plants, safety and health
standards, and practices and procedures and requirements relating to the
discharge of air and water pollutants. In addition, the Company could become
liable for the investigation and removal of any hazardous materials that may
be found on the plant sites regardless of the sources of such hazardous
materials. Failure to comply with any such statutes or regulations or any
change in the requirements of such statutes or regulations could result in
civil or criminal liability, imposition of cleanup liens and fines, large
expenditures to bring the facilities into compliance and cessation or
limitation of operations. See "Government Regulation--Environmental
Regulations".
 
                                      18
<PAGE>
 
  As of the date of this Prospectus, the Company has received no notice that
any required environmental regulatory approval has been revoked or that it is
in violation in any material respect as to any environmental law or regulation
applicable to its operations. There can be no assurance, however, that one or
more of such required regulatory approvals will not be revoked or that
environmental regulatory approvals required in the future will be obtained or
maintained or that notice of a violation will not be received.
 
CURTAILMENT BY POWER PURCHASERS
 
  Each power purchase agreement to which an existing Company venture is a
party authorizes the purchasing utility to curtail purchases for reasons of
system emergency, safety and repair and restoration of service. The power
purchase agreement with Con Ed in respect of the Linden Plant also permits
certain additional curtailment rights at the purchaser's sole discretion,
although the Company's cash flow attributable to the Linden Plant will not be
affected by any such curtailment so long as the Linden Plant meets its
capacity obligations. Under certain circumstances, PURPA authorizes utilities
to limit or discontinue purchases from QFs due to "operational circumstances".
This right to curtail purchases of power from QFs in the circumstances set
forth under PURPA is expressly excluded from Linden Venture's power purchase
agreement, but is included in certain of the Company's other power purchase
agreements. Although the effect of such curtailments has not been material to
the NJ Partnerships to date, there can be no assurance that there will not be
future curtailments under existing or future power purchase agreements or that
the effect thereof will not have a material adverse effect on the Company's
revenues and results of operations. Because the Company is unable to predict
the nature of any possible future curtailments, it is unable to predict the
impact thereof.
 
ABOVE MARKET POWER PURCHASE AGREEMENTS
 
  If the price to be paid by a power purchaser to one of the Company's QFs
under its power purchase agreement exceeds such power purchaser's actual
Avoided Cost for the electricity purchased, or if a power purchaser is
experiencing financial, regulatory or other pressures, such power purchaser
could attempt to amend or to terminate its power purchase agreement. See "--
Dependence Upon Third Parties". The Company understands that, currently, the
price to be paid by each of the purchasers of power from the existing ventures
in which the Company has an interest has been projected by such purchasers to
be above actual Avoided Cost for such purchasers of power for the remaining
term of each of the power purchase agreements. Although the provisions of the
power purchase agreements do not permit amendments or, absent a default by the
venture, early termination without the consent of the applicable venture and
while the provisions of the existing debt at the venture levels or the
applicable partnership agreements prohibit the giving of such consent without
the consent of venture lenders and other parties, it is possible that,
following a change in applicable legislation, case law or regulations, a court
or regulatory authority could order such an amendment or termination. Such
amendment or termination could materially and adversely affect the net
revenues of the applicable venture and, consequently, the cash flow available
to the Company for debt service and dividends on Common Stock. See "--
Dependence on Third Parties" and "--Risks Arising from Utility Regulation and
Deregulation".
 
EXPIRATION OF CERTAIN POWER PURCHASE AGREEMENTS
 
  Revenues of the Company's independent power ventures, and, therefore,
distributions to the Company, depend primarily upon payments to be made by the
purchasers of power from such ventures. While each of the Company's existing
power purchase agreements is a long term agreement--terms expire between 2008
and 2017--upon their expiration, renewal or replacement contracts may not have
comparably favorable terms, including terms as to price or duration,
especially since the existing power purchase agreements contain above-market
pricing provisions. Accordingly, upon any such expiration, the plant, assuming
legislation permits, may choose to continue to operate as a QF and sell
electricity at Avoided Cost rates under PURPA (and relevant regulations of
FERC and states implementing PURPA). So long as a plant is a QF, PURPA and the
implementing regulations currently in effect require electric utilities to
purchase the plant's electricity output in accordance with the current
requirements of PURPA and FERC's implementing and pricing regulations.

RISKS RELATED TO VENTURES WITHOUT LONG-TERM POWER PURCHASE AGREEMENTS     
 
  As an alternative to entering into long-term contracts with power
purchasers, a plant may become a merchant plant, selling electricity at market
prices dependent on the existence and decisions of merchant buyers, subject to
restrictions hereinafter noted. In addition, expanded capacity at existing
plants or new or acquired capacity may be sold as merchant power. If a plant
is not a QF, for it to operate as a merchant plant and to sell power at
market-based rates, it would require rate authorization from FERC. In granting
a request for market-based rate authority, FERC typically requires a showing
that the plant's owners and affiliates lack market power in the relevant
generation and transmission markets and in markets for related commerce such
as fuel. Obtaining FERC authority for market-based rates would also require a
showing by the seller that there is no opportunity for abusive affiliate
transactions involving any regulated affiliates of the Company that may exist
at the time. There can be no assurance that FERC market-based rate authority
would be obtained for any or all of the Company's existing or future plants to
operate as merchant plants. In addition, a merchant plant sells power based
upon market conditions at the time of sale, so that there can be no certainty
at present about the amount or timing of any revenues that may be received
from merchant power sales in the future or about the match between costs of
operations (in particular, fuel prices) and merchant power sales revenues.
   
  At present the Company's ventures have long-term agreements with power
purchasers. Although the terms of such contracts do not provide for, or have
been determined by applicable judicial decisions not to be subject to,
regulatory modification, the Company is unable to predict whether, over time,
any of its power purchasers would be able to abrogate such long-term contracts
through regulatory proceedings or insolvency proceedings. Any abrogation of
any of the Company's long-term power purchase agreements would have a material
adverse effect on the Company's revenues and results of operations. Because
the Company is unable to predict the timing or nature of any such possible
abrogations, it is unable to predict the impact thereof upon the Company. See
"--Curtailment by Power Purchasers" and "--Above Market Power Purchase
Agreements".     
 
DEPENDENCE ON THIRD PARTIES
 
  The nature of the Company's existing principal power plants is such that
each at present (except for the Bayonne Plant, which has two electrical power
and two steam customers, and the Linden Plant, which has two steam customers)
generally relies on one power customer and one steam sales customer
responsible for a substantial portion, if not all, of such plant's revenue.
During 1997, approximately 62.1%, 22.1% and 15.8% of the NJ Partnerships'
electricity revenue was attributable to revenue received pursuant to power
sales agreements with Con Ed, PSE&G and JCP&L, respectively. The existing
power and steam sales agreements (other than with respect to the steam sale
agreements of NJ Venture) are generally long-term agreements covering the sale
of electricity or steam for initial terms of up to 25 years. The loss of any
one power or steam sales agreement with any of these customers, the
deterioration in such customer's financial condition or any material failure
by any customer to fulfill its obligations under a power or steam sales
agreement could, therefore, have a material adverse effect on the Company's
results of operations. The loss of a steam customer also could jeopardize the
QF status of a Company plant. See "--Risks Arising From Utility Regulation and
Deregulation".
 
  Finally, each power plant depends on a single or limited number of entities
to supply and transport natural gas to such facility. The failure of any one
gas supplier or gas transporter to fulfill its contractual obligations could
have a material adverse effect on a particular venture and, consequently, on
the Company's business and results of operations. Because the Company is
unable to predict the nature of any possible future failure of a gas supplier
or transporter to fulfill its contractual obligations, it cannot predict the
impact thereof.
 
DEPENDENCE ON A SINGLE VENTURE
 
  Initially, the Company's ownership interests in Linden Venture will
contribute a substantial portion of the Company's expected net income and cash
flow, accounting for approximately 70% of its equity in earnings of the NJ
Partnerships on a pro forma combined basis for the year ended December 31,
1997. If Linden Venture's business were materially and adversely affected, the
Company's financial performance would be materially and adversely affected.
There can be no assurance that the Company's ownership interests in Linden
Venture will not continue to constitute the majority of the Company's assets
and to be the dominant source of income for the Company or that, from time to
time, another single asset or a small number of assets will not constitute the
majority of the Company's assets or the dominant source of its income.
 
                                      20
<PAGE>
 
   
RISKS OF SUBSTANTIAL FUEL COST INCREASES AND UNAVAILABILITY OF FUEL     
 
  Historically, each of the existing ventures' fuel acquisition strategy has
included various combinations of short-, medium- and long-term gas supply
contracts. In its gas supply arrangements, the Company has and expects to
match the fuel cost with the fuel component included in the relevant venture's
power sales agreements in order to minimize exposure to fuel price risk. There
can be no assurance, however, that gas supplies will be available for the full
term of the plants' power sales agreements, or that gas prices will not
increase in a manner that is disproportionate with the fuel component
provisions of the existing and future power purchase agreements or market
revenues for merchant plants. If gas is not available, or if gas prices
increase above that allowed by the fuel component provisions of the plants'
power sales agreements, or disproportionately to market revenues (in the case
of merchant sales), there could be a material adverse impact on the Company's
business and results of operations. To the extent that the Company does not
have long-term gas contracts that are closely matched to the fuel component of
a power purchase agreement or, to the extent to which there is not a full fuel
cost pass-through in the plant's power purchase agreements, these risks may be
exacerbated. While a particular plant may be entitled, or have the ability,
for short periods of time to use alternative fuels, such as butane or
kerosene, in the event of a gas interruption such back-up fuel arrangements
are designed only for short-term circumstances and do not eliminate the
inherent risks of longer-term, or frequent, gas supply interruptions.
Environmental and other permitting and operational considerations also
restrict the use of alternative fuels and may be particularly onerous should
the Company in the future acquire or develop other plants fueled by non-clean
burning fuels such as coal.
 
PROJECT DEVELOPMENT AND EXPANSION RISKS
 
  The development and expansion of power generation facilities are subject to
substantial risks. In connection with the development of a power generation
facility, the Company must obtain power sales agreements (or be prepared to
sell the plant's power without any such agreements as a merchant plant with
associated market risks), governmental permits and approvals, fuel supply and
transportation agreements, sufficient equity and debt financing, electrical
transmission service (if necessary), site agreements and construction
contracts and, in the case of cogeneration QFs, steam sales agreements. In
addition, project development and expansion is subject to certain
environmental, engineering and construction risks related to cost-overruns,
delays and performance. Although the Company may attempt to minimize its
financial risks in the development or expansion of a project by obtaining
favorable long-term power sales agreements, entering into power marketing
transactions, obtaining all required governmental permits and approvals and
arranging adequate financing prior to the commencement of construction, the
development or expansion of a power project may require the Company to expend
significant sums for preliminary engineering, permitting, legal and other
expenses before it can be determined whether a project is feasible,
economically attractive or capable of being financed. In addition, in
connection with any expansion of an existing project, the Company would be
required to obtain the consents of parties to existing agreements, venture
lenders and partners. If the Company were unable to complete the development
or expansion of a facility, it generally would not be able to recover its
investment in such development or expansion efforts. The process for obtaining
initial environmental, siting and other governmental permits and approvals is
complicated and lengthy, often taking more than a year, and is subject to
significant uncertainties. Moreover, as a result of competition, it may be
difficult to sell power or steam at prices achieved in prior agreements or at
acceptable rates in wholesale markets. There can be no assurance that the
Company will be successful in the development or expansion of power generation
facilities in the future. If a developmental or expansion effort is not
successful, the Company may be forced to abandon the development or expansion
efforts and, at the time of abandonment, to expense all capitalized
development costs incurred in connection therewith and to incur additional
losses associated with any contingent liabilities incurred as a result of such
activities.
 
  Should the Company engage in the construction and operation of new power
generation plants in carrying out its strategy, many risks would be involved,
including start-up problems, the breakdown or failure of equipment or
processes and performance below expected levels of output or efficiency. New
plants have no operating history and may employ recently developed and
technologically complex equipment. Insurance is maintained to protect against
certain of these risks, warranties are generally obtained for limited periods
relating
 
                                      21
<PAGE>
 
to the construction of a new plant and its equipment in varying degrees and
contractors and equipment suppliers are obligated to meet certain performance
levels. Such insurance, warranties and performance guarantees may, however,
not be adequate to cover lost revenues or increased expenses and, as a result,
a venture may be unable to fund principal and interest payments under its
financing obligations and may operate at a loss. A default under any such
financing obligations could result in the Company losing its interest in any
such new power generation facility developed by the Company and in other
adverse consequences to the Company.
 
ACQUISITION RISKS
 
  The Company's strategy is based in part on making selective and
opportunistic acquisitions. In this regard, the Company has no history or
experience in making significant acquisitions. Moreover, although the domestic
power industry is undergoing consolidation and the Company believes that
significant acquisition opportunities may be available to it, the Company is
likely to confront significant competition for acquisition opportunities. See
"--Competition". In addition, there can be no assurance that the Company will
be able to identify attractive acquisition opportunities at economically
justifiable prices or, to the extent that any opportunities are identified,
that the Company will be able to obtain the necessary financing and take the
other actions that will be necessary to consummate any such acquisitions.
Further, any future acquisitions of power generation plants could be subject
to significant regulation, both as to ownership and operational
considerations. See "--Risks Arising From Utility Regulation and
Deregulation".
 
RISKS AS TO AVAILABILITY OF CAPITAL
 
  Continued access to capital with acceptable terms is necessary to assure the
success of future ventures, acquisitions and expansions and, therefore, to
assure the success of the Company's strategy. The Company's ventures
historically have used project financing to fund the capital expenditures
associated with developing and constructing the power generation plants in
which they have an interest. Project financing borrowings are substantially
non-recourse to the Company and generally are secured by the physical assets,
partnership or other equity interests, venture contracts and cash flow of the
subject venture. In connection with future acquisitions or the development of
additional cogeneration plants, the Company intends to seek, where possible,
such non-recourse project financing. The Company's ability to carry out its
strategy of development and acquisition of additional ventures will be, in
part, dependent upon the Company's ability to generate cash flows or to obtain
its own debt or equity financing for its equity or subordinated loan
participations in, and provision of credit support with respect to, such
ventures. The Company's ability to arrange for financing on either a full
recourse or substantially non-recourse basis and the cost of such capital are
dependent upon general economic and capital market conditions, the
availability of bank and other credit, investor confidence in the Company, the
continued success of current ventures and provisions of tax and other laws
which are conducive or encouraging to the raising of capital for power
generation ventures. Should future access to capital not be available, the
Company may be required to abandon its strategy with respect to the
development and acquisition of additional projects. While any such effect
would not necessarily adversely affect the results of operations of the
Company with respect to its currently operating facilities, the inability of
the Company to expand currently owned plants, build new plants or acquire
existing facilities would significantly affect the future growth of the
Company.
 
  If lenders were to require the Company to guarantee the indebtedness of a
subsidiary or venture in respect of any future plant, the Company's general
corporate funds could be vulnerable in the event of a default by such
subsidiary or venture, and if the Company were unable to incur indebtedness in
respect of such guarantees under the restrictions on indebtedness (including
guarantees) contained in the Indenture or the Bridge Loan (as defined herein)
or under other then existing debt agreements, the Company's ability to fund
new plants could be adversely affected.
 
FLUCTUATIONS IN QUARTERLY PERFORMANCE
 
  Historically, the Company's quarterly operating results have varied,
reflecting seasonal capacity payments received in the summer months, fuel
matters, dispatch and unscheduled maintenance by the plants in which the
 
                                      22
<PAGE>
 
Company has an interest. The highest demands for electricity in the geographic
areas which the Company currently serves are generally in the summer months,
when demand for electricity to generate cooling is the greatest. Fluctuations
in quarterly performance, and the extent to which fluctuations in quarterly
performance can affect year to year performance, can adversely affect the
market price of the Common Stock.
 
DEPENDENCE ON SENIOR MANAGEMENT
 
  The Company's management and operations are dependent upon the efforts of
the Company's Chairman of the Board, President and Chief Executive Officer,
Robert C. McNair, and a small number of management and operating personnel.
The Company does not maintain key-man life insurance on any executive officer
or other key member of the management of the Company. The loss of the services
of Mr. McNair or of any other key member of management could have a material
adverse impact on the Company. See "Management".
 
CONTROL BY PRINCIPAL STOCKHOLDER
   
  Upon completion of the Common Stock Offering, entities controlled directly
or indirectly by Robert C. McNair and members of his family will own in the
aggregate approximately 33.6% of the outstanding Common Stock (25.2% if the
underwriters' over-allotment option is exercised in full). Accordingly, Mr.
McNair, through entities controlled by him and his family, will be able to
exercise substantial influence on the election of the directors of the Company
and to exercise substantial influence on the Company's management, operations
and affairs, all in addition to the influence that Mr. McNair will have on the
Company's affairs as Chairman of the Board, President and Chief Executive
Officer of the Company. The effect of Mr. McNair's control and influence on
the Company could be to reduce the ability of other stockholders to influence
the direction of the Company. See "Principal and Selling Stockholders". In
addition, the Company currently has, and will continue to have, a variety of
contractual relationships with affiliates of Mr. McNair. See "Management" and
"Certain Transactions".     
 
HISTORICAL ABSENCE OF PUBLIC MARKET
 
  Prior to the Common Stock Offering, there has been no public market for the
Common Stock. Although the Company has applied for listing of the Common Stock
on the NYSE, there can be no assurance that such listing will be obtained or
that an active trading market will develop, or that if developed, it will
continue upon completion of the Common Stock Offering. If an active market for
the Common Stock does not develop or is not sustained, the trading prices for
the Common Stock could be materially adversely affected. The initial public
offering price of the Common Stock will be determined by negotiations between
the Company and the Underwriters and may not be indicative of the market price
of the Common Stock after the Common Stock Offering. For a discussion of the
factors to be considered in determining the initial public offering price, see
"Underwriters". The market price of the Common Stock could be subject to
significant fluctuations in response to variations in quarterly and yearly
operating results, the success of the Company's business strategy, general
trends in the independent power industry, competition, technological
obsolescence, changes in federal and state regulations affecting the Company
or affecting the power industry and other factors. In addition, the stock
market in recent years has from time to time experienced extreme price and
volume fluctuations that have often been unrelated or disproportionate to the
operating performance of affected companies. These broad fluctuations may
adversely affect the market price of the Common Stock.
 
POSSIBLE ADVERSE EFFECT ON MARKET PRICE OF ANTI-TAKEOVER PROVISIONS
 
  Cogen's Certificate of Incorporation and Bylaws include a number of
provisions that may have the effect of encouraging persons considering
unsolicited tender offers or other unilateral takeover proposals to negotiate
with the Board of Directors rather than pursue non-negotiated takeover
attempts. These provisions may have the effect of delaying, deferring or
preventing a change in control of the Company whether or not such person
chooses to negotiate with the Board of Directors and may adversely affect the
market price of the Common Stock. The
 
                                      23
<PAGE>
 
provisions include authorized "blank check" preferred stock, the denial of the
use of written consents, a classified board of directors, restrictions on
removal of directors and advance notice requirements with respect to
stockholder meetings as to director nominations and stockholder proposals. See
"Description of Capital Stock".
 
POTENTIAL ADVERSE EFFECT ON MARKET PRICE OF SHARES ELIGIBLE FOR FUTURE SALE
 
  Immediately following the Common Stock Offering, 55,000,000 shares of Common
Stock will be outstanding. The 33,333,333 shares of Common Stock offered
hereby, together with any shares offered upon exercise of the Underwriters'
over-allotment option or under the Company's stock plans, will be eligible for
resale in the public market without restrictions under the Securities Act,
except to the extent that those shares are acquired by affiliates of the
Company. All of the remaining outstanding shares of Common Stock will be
subject to resale in accordance with Rule 144 under the Securities Act. In
addition, the Selling Stockholders have agreed not to sell, transfer or
otherwise dispose of their shares of Common Stock not sold pursuant to the
Common Stock Offering for a period of 180 days beginning on the date of this
Prospectus. Sales of a substantial number of shares of Common Stock may
adversely affect the market price of the Common Stock. See "Shares Eligible
for Future Sale".
 
                                      24
<PAGE>
 
                                 DEBT OFFERING
   
  Concurrently with the Common Stock Offering, the Company is offering an
aggregate of $400.0 million of secured Senior Notes to the public. The Senior
Notes will be secured, on a pari passu basis with the senior secured bank
indebtedness, by a security interest granted by the Company on certain direct
wholly-owned subsidiaries of the Company, which subsidiaries own all of the
Company's equity interests in the ventures. The Indenture to be executed in
conjunction with the Debt Offering will contain certain covenants, including
restrictive covenants that (i) limit indebtedness of the Company, other than
the Senior Notes, up to $300.0 million at any one time outstanding in senior
secured bank indebtedness, certain other parity indebtedness the issuance of
which either is incurred in compliance with a coverage ratio requirement or
will not result in a rating downgrade of the Senior Notes and subordinated
indebtedness, (ii) limit additional indebtedness of the ventures (except
Selkirk Venture) in which the Company currently has an interest, other than up
to $100.0 million at any one time outstanding for plant improvements and
expansion and amounts required to satisfy any fiduciary responsibilities of
the partners or venturers of each of the ventures, and (iii) prohibit
distributions to stockholders and on account of subordinated indebtedness owed
to affiliates unless no default exists under the Indenture and such
distributions do not exceed 100% of Funds From Operations (as of the closing
date of the issuance of the Senior Notes) plus $50.0 million. The Indenture
will further contain provisions that upon achieving a prescribed level of
diversification of interests owned by the Company in at least eight power
project ventures, the foregoing mandatory redemption provisions, covenants
and, subject to a further condition, security interest, and certain events of
default, will be terminated. The closings of each of the Common Stock Offering
and the Debt Offering are conditioned upon the consummation of the other. In
conjunction with the Formation Transactions and immediately prior to the
closing of the Common Stock Offering, Morgan Stanley & Co. Incorporated will
loan (the "Bridge Loan") $291.0 million to Linden Ltd. pursuant to a loan
agreement (the "Bridge Loan Agreement"). The Company expects that it will
advance as a loan to Linden Ltd. a portion of the proceeds of the Debt
Offering necessary for Linden Ltd. to repay the Bridge Loan in full. See
"Description of Senior Notes and Certain Other Indebtedness--Description of
Senior Notes".     
 
                                DIVIDEND POLICY
 
  As a newly formed entity, the Company has not paid any dividends. Because of
the nature of the Company's business, however, and the cash flow expected by
the Company from the operation of the independent power plants in which it has
interests, as described elsewhere in this Prospectus, the Company expects that
for the foreseeable future a substantial part of its earnings will be paid in
dividends to its stockholders. While there can be no assurance that earnings
will be available for distribution or that such dividends actually will be
distributed or that they will be continued at any particular level for any
particular period of time, the Company expects to pay annual dividends for the
foreseeable future on the Common Stock at the rate of $      per share per
quarter. The declaration of dividends is at the discretion of the Company's
Board of Directors and will be subject to the terms of the Company's debt
agreements, including the Indenture, concerning restricted payments. The
Company's dividend policy will be reviewed by the Board of Directors at such
future time as may be appropriate in light of relevant factors at that time.
During the initial years of the Company's operations, dividends with respect
to the Common Stock are expected to exceed the share of the current and
accumulated earnings and profits of the Company allocable to the holders of
the Common Stock (as determined for United States federal income tax
purposes). In such a case, such excess generally would be treated as a tax-
free return of capital up to a holder's basis in such holder's shares of
Common Stock and as capital gain thereafter. Any such excess would not be
eligible for the dividends-received deduction with respect to dividends paid
to corporate holders of the Common Stock. (To the extent a holder receives
dividends which constitute a return of capital to such holder, the holder's
basis in the shares upon which dividends are paid will be reduced. See
"Certain United States Federal Income Tax Consequences--U.S. Holders--Sale or
Other Disposition of Company Stock.") No assurance can be given, however, that
such distributions will in fact exceed the Company's current and accumulated
earnings and profits for such purposes or, if any such distributions are made,
regarding the amount of any such excess. See "Certain United States Federal
Income Tax Consequences--U.S. Holders--Dividends". The Company's ability to
pay dividends will, in any event, always be dependent upon cash flow received
from distributions to it by its subsidiaries, which are in turn dependent upon
distributions from the ventures. As described elsewhere in this Prospectus,
the ventures in which the Company has an interest and obtains its cash flow
are subject to restrictions with respect to distributions to their holders of
equity. See "Description of Senior Notes and Certain Other Indebtedness--Plant
Project Financings".

                                CAPITALIZATION
   
  Cogen was formed in May 1998. The following table sets forth the pro forma
capitalization of the Company at June 30, 1998, based on the historical
capitalization of the Group at June 30, 1998, as adjusted to reflect the
capitalization of the Company giving effect to consummation of the Common
Stock Offering, the Debt Offering and the Formation Transactions and the
application of a portion of the proceeds of the Debt Offering to retire the
Bridge Loan, as if all such transactions had occurred on June 30, 1998.     
   
  The Common Stock Offering relates to the sale by the McNair Interests and
the Minority Interests of 33,333,333 shares of Common Stock which they
received in the Formation Transactions. The Company has agreed to pay certain
costs and expenses related to the Common Stock Offering, which are expected to
total $1.8 million. The Company will not receive any proceeds from the Common
Stock Offering.     
   
  Concurrently with the Common Stock Offering the Company is offering an
aggregate of $400.0 million of Senior Notes comprising $100.0 million of   %
Senior Notes due 2005 (the "2005 Notes"), $150.0 million of   % Senior Notes
due 2010 (the "2010 Notes") and $150.0 million of   % Senior Notes due 2018
(the "2018 Notes"). The Senior Notes have no sinking fund requirements, and no
principal payments are due prior to maturity. See "Description of Senior Notes
and Certain Other Indebtedness--Description of Senior Notes" for a description
of certain covenants with respect to the Senior Notes. The proceeds from the
Debt Offering will be used to loan an amount to Linden Ltd. for repayment of
the Bridge Loan, to retire amounts payable to affiliates, to pay expenses
relating to the Formation Transactions and the Offerings and for working
capital purposes.     
   
  The Formation Transactions consist of: (i) the acquisition by the Company of
49.9% of the general and limited partnership interests of Linden Ltd. from the
McNair Interests and the Minority Interests for an aggregate of 28.7 million
shares of Common Stock with an estimated market value of $429.7 million; (ii)
the acquisition by the Company of 100% of the outstanding common stock of
Camden, Inc. from the McNair Interests and the limited partnership interests
in Camden GPLP held by the Minority Interests for an aggregate of $1.0 million
in cash and an aggregate of 9.9 million shares of Common Stock with an
estimated market value of $147.9 million; (iii) the acquisition by the Company
of MESC pursuant to the terms of a merger agreement under which the McNair
Interests and the Minority Interests, the holders of the common stock of MESC,
will receive an aggregate of 14.4 million shares of Common Stock with an
estimated market value of $217.4 million; (iv) the acquisition by the Company
of the general and limited partnership interests in Selkirk LP held by the
McNair Interests and the Minority Interests for an aggregate of 1.7 million
shares of Common Stock with an estimated market value of $25.2 million; (v)
the acquisition by the Company of 100% of the general and limited partnership
interests of CT Global from the McNair Interests and the Minority Interests
for an aggregate of 0.3 million shares of Common Stock with an estimated
market value of $4.8 million; and (vi) the redemption by Linden Ltd. of 50.1%
of its general and limited partnership interests not acquired by the Company
for a $140.4 million account receivable from Cogen Technologies Financial
Services, L.P., a limited partnership owned by the McNair Interests and the
Minority Interests ("Financial Services"), and $291.0 million in cash. The
dollar and share amounts described in the immediately preceding sentence are
estimates based on an assumed Common Stock Offering price of $15.00 per share.
       
  Immediately prior to the consummation of the Formation Transactions and
Common Stock Offering, Morgan Stanley & Co. Incorporated ("Morgan Stanley")
will loan $291.0 million to Linden Ltd. pursuant to the Bridge Loan, which
Linden Ltd. will use to redeem the 50.1% of its general and limited
partnership interests, as previously discussed. The Bridge Loan will be
evidenced by a subordinated promissory note in favor of Morgan Stanley, which
note will bear interest at the rate of 24% per annum. Immediately following
the consummation of the Debt Offering, the Company will loan $291.0 million of
the proceeds of the Debt Offering to Linden Ltd. for repayment of the Bridge
Loan.

                         UNAUDITED PRO FORMA CONDENSED
                             FINANCIAL STATEMENTS
   
  Cogen was formed in May 1998. The following unaudited pro forma condensed
financial statements give effect to (i) the acquisition of an additional,
indirect 5.25% limited partnership interest in NJ Venture, (ii) the Formation
Transactions, (iii) the Common Stock Offering, (iv) the Bridge Loan and (v)
the issuance of the Senior Notes and the application of a portion of the
proceeds thereof to loan an amount to Linden Ltd. for repayment of the Bridge
Loan, to retire amounts payable to affiliates and to pay expenses relating to
the Formation Transactions and the Offerings, based on the historical combined
financial statements of the Group, under the assumptions and adjustments set
forth in the footnotes accompanying the unaudited pro forma condensed
financial statements. No pro forma adjustments relating to the organization of
the Company are shown because the amounts are de minimis. The unaudited pro
forma condensed statements of income for the six months ended June 30, 1998
and the year ended December 31, 1997 assume such transactions were consummated
on January 1, 1997. The unaudited pro forma condensed balance sheet at June
30, 1998 assumes such transactions were consummated on June 30, 1998. The
adjustments contained in the unaudited pro forma condensed statements of
income do not give effect to any nonrecurring costs directly associated with
such transactions that might be incurred within the next twelve months and do
not give effect to any potential cost savings and synergies that could result
from such transactions. The unaudited pro forma condensed financial statements
have been prepared for informational purposes only and are not necessarily
indicative of the actual or future results of operations or financial
condition that would have been achieved had the transaction occurred at the
dates assumed. The unaudited pro forma condensed financial statements should
be read in conjunction with the historical combined financial statements of
the Group and the related notes thereto included elsewhere in this Prospectus.
       
  The amounts shown in the column entitled "Group Historical" reflect the
combined financial statements of MESC and its wholly owned subsidiary NJ Inc.,
Camden Inc., Linden Ltd., Selkirk LP, CT Global and the limited partnership
interests in Camden GPLP not held by Camden Inc., the entities acquired in the
Formation Transactions.     
   
  The Formation Transactions consist of: (i) the acquisition by the Company of
49.9% of the general and limited partnership interests of Linden Ltd. from the
McNair Interests and the Minority Interests for an aggregate of 28.7 million
shares of Common Stock with an estimated market value of $429.7 million; (ii)
the acquisition by the Company of 100% of the outstanding common stock of
Camden, Inc. from the McNair Interests and the limited partnership interests
in Camden GPLP held by the Minority Interests for $1.0 million in cash and an
aggregate of 9.9 million shares of Common Stock with an estimated market value
of $147.9 million; (iii) the acquisition by the Company of MESC pursuant to
the terms of a merger agreement under which the McNair Interests and the
Minority Interests, the holders of the common stock of MESC, will receive an
aggregate of 14.4 million shares of Common Stock with an estimated market
value of $217.4 million; (iv) the acquisition by the Company of the general
and limited partnership interests in Selkirk LP held by the McNair Interests
and the Minority Interests for an aggregate of 1.7 million shares of Common
Stock with an estimated market value of $25.2 million; (v) the acquisition by
the Company of 100% of the general and limited partnership interests of CT
Global from the McNair Interests and the Minority Interests for an aggregate
of 0.3 million shares of Common Stock with an estimated market value of $4.8
million; and (vi) the redemption by Linden Ltd. of the 50.1% of its general
and limited partnership interests not acquired by the Company for a $140.4
million account receivable from Financial Services and $291.0 million in cash.
The dollar and share amounts described in the immediately preceding sentence
are estimates based on an assumed Common Stock Offering price of $15.00 per
share. Prior to the consummation of the Formation Transactions, the Company
had no ownership interest in such entities.     
 
  The Common Stock Offering relates to the sale by the McNair Interests and
the Minority Interests of 33,333,333 shares of Common Stock which they
received in the Formation Transactions. The Company has agreed to pay certain
costs and expenses related to the Common Stock Offering which are expected to
total approximately $1.8 million. The Company will not receive any proceeds
from the Common Stock Offering. The unaudited pro forma condensed financial
statements assume a Common Stock Offering price of $15.00 per share.

  Immediately prior to the consummation of the Formation Transactions and
Common Stock Offering, Morgan Stanley will loan $291.0 million to Linden Ltd.
pursuant to the Bridge Loan, which Linden Ltd. will use to redeem the 50.1% of
its general and limited partnership interests, as previously discussed. The
Bridge Loan will be evidenced by a subordinated promissory note in favor of
Morgan Stanley, which note will bear interest at the rate of 24% per annum.
Immediately following the consummation of the Debt Offering, the Company will
loan $291.0 million of the proceeds of the Debt Offering to Linden Ltd. for
repayment of the Bridge Loan.     
 
  Concurrently with the Common Stock Offering the Company is offering an
aggregate of $400.0 million of Senior Notes comprising $100.0 million of 2005
Notes, $150.0 million of 2010 Notes and $150.0 million of 2018 Notes. The
Senior Notes have no sinking fund requirements and no principal payments are
due prior to maturity. See "Description of Senior Notes and Certain Other
Indebtedness--Description of Senior Notes" for a description of certain
covenants with respect to the Senior Notes. The proceeds from the Senior Notes
will be used to loan an amount to Linden Ltd. for repayment of the Bridge
Loan, to retire amounts payable to affiliates, to pay expenses relating to the
Formation Transactions and the Offerings and for working capital purposes.

 (1) Prior to the consummation of the Formation Transactions, Linden Venture,
     Camden Cogen and Selkirk LP will make one-time payments totaling $83.7
     million to terminate certain agreements with affiliates with respect to
     the payment of management and gas management fees. "See Certain
     Transactions--Formation Transactions". Such management and gas management
     fees were paid based on a percentage of gross revenues and gas purchases,
     respectively. Costs included in the historical and pro forma amounts for
     equity in earnings of affiliates associated with the agreements which are
     being terminated are $2.4 million for Linden Venture, $0.6 million for
     Camden Cogen and $0.7 million for Selkirk Cogen.     
       
    The historical and pro forma amounts for operating overhead include $13.3
    million of one-time payments to "buy out" development bonuses which were
    previously granted to certain employees and were being charged to expense
    as earned over subsequent periods. The Group will make additional one-time
    payments totaling $14.9 million prior to the consummation of the Formation
    Transactions to buy out all remaining development bonuses. The historical
    and pro forma amounts for operating overhead also include $1.6 million
    with respect to development bonuses earned during the period.     
       
    Prior to the consummation of the Formation Transactions, the Group used a
    corporate aircraft owned by an affiliate and was charged for such use
    based on the affiliate's cost to own and operate the aircraft and the
    Group's proportionate useage. Such aircraft will not be acquired by the
    Company in the Formation Transactions. If such aircraft is used by the
    Company subsequent to the consummation of the Formation Transactions, the
    Company will be charged based on commercial airline rates. The historical
    and pro forma     
 
                                      30
<PAGE>
 
        
     amounts for general and administrative expense include $3.0 million with
     respect to the use of such aircraft.     
 
 (2) Reflects the equity in the earnings of NJ Venture attributable to a 5.25%
     limited partnership interest acquired from an unaffiliated entity in July
     1998. See "--Management's Discussion and Analysis of Financial Condition
     and Results of Operations--General".
   
 (3) Reflects the amortization of excess cost related to the purchase of 10.5%
     of the outstanding common stock of MESC. Such excess cost has been
     allocated to MESC's investment in NJ Venture and is being amortized over
     the remaining life of NJ Venture's power purchase agreement which is 10
     years.     
   
 (4) Reflects interest expense associated with the Senior Notes assuming
     interest rates as follows: $100.0 million at 6.72%, $150.0 million at
     6.89% and $150.0 million at 7.33%.     
   
 (5) Reflects the amortization of deferred costs and expenses related to the
     issuance of the Senior Notes. The Company will incur an estimated $5.7
     million in costs in connection with the issuance of the Senior Notes and
     such costs are being deferred and amortized over the life of the Senior
     Notes, 25% over seven years, 37.5% over 12 years and 37.5% over 20 years.
            

 (6) Reflects the effect of income taxes on the Group's historical results
     since the Company will be a taxable entity. Camden Inc. is an S
     corporation and Linden Ltd. and Selkirk LP are partnerships and income
     taxes are recognized by the individual partners or shareholders (with the
     exception of New Jersey state income taxes which are recognized by Camden
     Inc.). Accordingly, such income taxes are not recognized in the
     historical financial statements. Following the Formation Transactions the
     Company will be the partner or shareholder of such entities and such
     income taxes will be recognized in its financial statements. Such
     adjustment assumes the Company is subject to federal income taxes at a
     rate of 35% and to New Jersey state income taxes at a rate of 9% on
     income allocable to that state. The average effective rate is
     approximately 38%.     
   
 (7) Reflects the income tax effects of the pro forma adjustments. Such
     adjustment assumes the Company is subject to federal income taxes at a
     rate of 35% and to New Jersey state income taxes at a rate of 9% on
     income allocable to that state. The average effective rate is
     approximately 38%.     
   
 (8) Reflects the issuance of 55,000,000 shares in the Formation Transactions.

 (1) Pro forma amounts do not reflect approximately $1.8 million in
     nonrecurring costs which will be borne by the Company on behalf of the
     Selling Stockholders in association with the Common Stock Offering and
     $1.9 million (net of related tax benefit of $1.0 million) in nonrecurring
     costs associated with the Formation Transactions, as such costs will be
     included in the results of operations of the Company within the twelve-
     month period following the consummation of such transactions. Such costs
     principally consist of legal, accounting, printing and other related
     costs. Since such costs have no future benefit to the Company, they are
     being charged to expense as incurred.     
       
     Prior to the consummation of the Formation Transactions Linden Venture,
     Camden Cogen and Selkirk LP will make one-time payments totaling $83.7
     million to terminate certain agreements with affiliates with respect to
     the payment of management and gas management fees. "See Certain
     Transactions--Formation Transactions". Such management and gas management
     fees were paid based on a percentage of gross revenues and gas purchases,
     respectively. Costs included in the historical and pro forma amounts for
     equity in earnings of affiliates associated with the agreements which are
     being terminated are $5.3 million for Linden Venture, $1.4 million for
     Camden Cogen and $1.4 million for Selkirk Cogen.     
       
     Prior to the consummation of the Formation Transactions the Group will
     make one-time payments totaling $28.2 million to "buy out" development
     bonuses which were previously granted to certain employees and     
 
                                      32

     were being charged to expense as earned over subsequent periods. The
     historical and pro forma amounts for operating overhead also include $4.7
     million with respect to development bonuses earned during the period.     
        
     Prior to the consummation of the Formation Transactions the Group utilized
     a corporate aircraft owned by an affiliate and was charged based on the
     affiliate's cost to own and operate the aircraft and the Group's
     proportionate useage. Such aircraft will not be acquired by the Company in
     the Formation Transactions. If such aircraft is used by the Company
     subsequent to the consummation of the Formation Transactions, the Company
     will be charged based on commercial airline rates. The historical and pro
     forma amounts for general and administrative expense include $8.6 million
     with respect to the use of such aircraft.     
   
 (2) Reflects the equity in the earnings of NJ Venture attributable to a 5.25%
     limited partnership interest acquired from an unaffiliated entity in July
     1998. See "--Management's Discussion and Analysis of Financial Condition
     and Results of Operations--General".     
   
 (3) Reflects the amortization of excess cost related to the purchase of 10.5%
     of the outstanding common stock of MESC. Such excess cost has been
     allocated to MESC's investment in NJ Venture and is being amortized over
     the estimated useful life of NJ Venture's assets and power purchase
     agreement which is an average of approximately 20 years.     
   
 (4) Reflects interest expense associated with the Senior Notes assuming
     interest rates as follows: $100.0 million at 6.72%, $150.0 million at
     6.89% and $150.0 million at 7.33%.     
   
 (5) Reflects the amortization of deferred costs and expenses related to the
     issuance of the Senior Notes. The Company will incur an estimated $5.7
     million in costs in connection with the issuance of the Senior Notes and
     such costs are being deferred and amortized over the life of the Senior
     Notes, 25% over seven years, 37.5% over 12 years and 37.5% over 20 years.
            
 (6) Reflects the effect of income taxes on the Group's historical results
     since the Company will be a taxable entity. Camden Inc. is an S
     corporation and Linden Ltd. and Selkirk LP are partnerships and income
     taxes are recognized by the individual partners or stockholders (with the
     exception of New Jersey state income taxes which are recognized by Camden
     Inc.). Accordingly, such income taxes are not recognized in the
     historical financial statements. Following the Formation Transactions the
     Company will be the partner or shareholder of such entities and such
     income taxes will be recognized in its financial statements. Such
     adjustment assumes the Company is subject to federal income taxes at a
     rate of 35% and to New Jersey state income taxes at a rate of 9% on
     income allocable to that state. The average effective rate is
     approximately 38%.     
   
 (7) Reflects the income tax effects of the pro forma adjustments. Such
     adjustment assumes the Company is subject to federal income taxes at a
     rate of 35% and to New Jersey state income taxes at a rate of 9% on
     income allocable to that state. The average effective rate is
     approximately 38%.     
   
 (8) Reflects the issuance of 55,000,000 shares in the Formation Transactions.

(1) To reflect the acquisition of an additional, indirect 5.25% limited
    partnership interest in NJ Venture from an unaffiliated entity in July
    1998 for $12.5 million.
   
(2) To reflect acquisitions from the McNair Interests and the Minority
    Interests as follows: (i) 49.9% of the limited and general partnership
    interests in Linden Ltd. for an aggregate of 28.7 million shares of Common
    Stock with an estimated market value of $429.7 million; (ii) 100% of the
    outstanding common stock of Camden Inc. from the McNair Interests and the
    limited partnership interests in Camden GPLP held by the Minority
    Interests for $1.0 million in cash and an aggregate of 9.9 million shares
    of Common Stock with an estimated market value of $147.9 million; (iii)
    89.5% of the outstanding common stock of MESC for an aggregate of 12.9
    million shares of Common Stock with an estimated market value of 194.6
    million; and (iv) 100% of the outstanding common stock of CT Global for an
    aggregate of 0.3 million shares of Common Stock with an estimated market
    value of $4.8 million. The dollar and share amounts described in the
    immediately preceding sentence are estimates based on an assumed Common
    Stock Offering price of $15.00 per share. Prior to the consummation of the
    Formation Transactions, the Company had no ownership interest in such
    entities.     
       
    Prior to the Formation Transactions the ownership interests of the McNair
    Interests and the Minority Interests discussed in the preceding paragraph
    with respect to each of such entities acquired by the Company are
    identical. Following the Formation Transactions with respect to such
    entities the ownership interest of the McNair Interests and certain of the
    Minority Interests in the Company will be identical to their prior
    interests in the entities acquired. Accordingly, such transactions are
    being accounted for at historical cost as a reorganization of entities
    under common control.     
       
    The valuations were agreed to in arms-length negotiations as discussed in
    Note 9 to the combined financial statements of Cogen Technologies Group
    included elsewhere in this Prospectus. The price per share is equal to the
    Common Stock Offering price.     
       
    The effect of such transactions on the historical balance sheet is as
    follows (in millions of dollars):

    The transactions to acquire the interests in Linden Ltd. and Camden Inc.
    are taxable transactions and, accordingly, deferred federal and New Jersey
    state income taxes have been provided based on the excess of the new tax
    bases over the net book value of the interest acquired at an effective
    rate of approximately 38%. The recognition of the deferred income taxes
    and the cash included in the Camden transaction results in an increase in
    Owners' Equity. The transactions with respect to MESC and CT Global are
    not taxable and have no effect on the historical balance sheet.     
   
(3) To reflect $291.0 million in borrowings by Linden Ltd. under the terms of
    the Bridge Loan.     
   
(4) To reflect the redemption by Linden Ltd. of the remaining outstanding
    general and limited partnership interests (which are held by the McNair
    Interests and the Minority Interests) in exchange for a $140.4 million
    account receivable and $291.0 million in cash. The transaction, net of
    related deferred federal and New Jersey state income taxes of $169.8
    million, results in a reduction in Owners' Equity of $261.6 million.
    Deferred income taxes have been provided at an effective rate of
    approximately 38% based on the difference between the tax basis and book
    basis of the partnership interests being redeemed. The valuation of such
    interests is based on arms-length negotiations discussed in Note 9 to the
    combined financial statements of Cogen Technologies Group included
    elsewhere in this Prospectus.     
   
(5) To reflect the issuance of 1.7 million shares of Common Stock, valued at
    $25.2 million, in exchange for 100% of the limited and general partnership
    interests in Selkirk LP. The 81.7% of such interests acquired

     from the McNair Interests is accounted for at historical cost as a
     reorganization of entities under common control. The acquisition of the
     18.3% of such interests acquired from the Minority Interests is accounted
     for as a purchase. The valuation of such interests was agreed to in arms-
     length negotiations as discussed in Note 9 to the combined financial
     statements of Cogen Technologies Group included elsewhere in this
     Prospectus. The purchase price of the interests acquired from the Minority
     Interests, 0.3 million shares valued at $4.5 million, is equal to book
     value and approximates fair value. Such amount has been allocated to
     Selkirk LP's assets and liabilities in amounts equal to the book value of
     such assets and liabilities.     
   
(6)  To reflect the issuance of 1.5 million shares of Common Stock, valued at
     $22.8 million, in exchange for 10.5% of the outstanding shares of common
     stock of MESC which is held by certain of the Minority Interests. Such
     transaction is accounted for as a purchase.     
       
    The valuation of such interests was agreed to in arms-length negotiations
    as discussed in Note 9 to the combined financial statements of Cogen
    Technologies Group included elsewhere in this Prospectus. The purchase
    price has been allocated to MESC's assets and liabilities in amounts equal
    to their book value and the cost in excess of such book value, $38.2
    million (which includes $13.9 million of deferred tax liabilities), has
    been allocated to MESC's investment in NJ Venture and will be amortized
    over the remaining life of NJ Venture's power purchase agreement which is
    10 years.     
   
(7) To reflect the issuance of $400.0 million of Senior Notes.     
   
(8) To reflect the use of a portion of the proceeds from the Debt Offering
    for: (i) the loan by the Company to Linden Ltd. of $291.0 million for the
    repayment of the Bridge Loan; (ii) the payment of costs and expenses
    related to the Common Stock Offering; (iii) the payment of costs and
    expenses related to the Debt Offering; (iv) the payment of costs and
    expenses related to the Formation Transactions; and (v) the retirement of
    accounts payable to affiliates. The effect of such transactions on the
    historical balance sheet is as follows (in millions of dollars):

    The Company has agreed to bear certain costs and expenses of the Common
    Stock Offering on behalf of the Selling Stockholders; since such
    expenditures have no future benefit to the Company, they are being charged
    to earnings as incurred. The costs and expenses related to the Debt
    Offering will be amortized over the life of the Senior Notes. The costs
    and expenses related to the Formation Transactions are being charged to
    earnings as incurred.     
       
    The costs of the Formation Transactions include $2.5 million which will be
    capitalized and amortized for income tax purposes and $0.4 million which
    is not deductible for income tax purposes. The $1.0 million deferred
    income tax asset reflects future federal and New Jersey state income tax
    benefits at an effective rate of approximately 38%.     
   
(9) To reflect a $2.9 million payment by Camden Cogen to its limited partner
    under the tax indemnity provisions of Camden Cogen's limited partnership
    agreement due to the termination of the tax partnership as a result of the
    Formation Transactions. The transaction, net of a related deferred federal
    and New Jersey state income tax benefit of $1.1 million, results in a $1.8
    million reduction in Owners' Equity.     
   
(10) To reclassify historical deferred income tax liabilities to reflect a net
     presentation in the balance sheet.

          MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                           AND RESULTS OF OPERATIONS
 
  The following discussion should be read in conjunction with the combined
financial statements of the Group and the NJ Partnerships and the notes
thereto included elsewhere herein. Certain information contained herein,
including information with respect to the Company's plans and strategy for its
business, are forward-looking statements. Prospective investors should
consider carefully the factors set forth under the caption "Risk Factors" for
a discussion of important factors that could cause actual results to differ
materially from any forward-looking statements contained in this Prospectus.
 
GENERAL
 
  Cogen was formed in May 1998 at the instance of Robert C. McNair and to date
has conducted no operations. Upon consummation of the Formation Transactions
Cogen will acquire control of a group of affiliated entities engaged in the
ownership and operation of power generation plants in the Northeastern United
States. The Company will have interests in four power plants having an
aggregate capacity of 1,382 megawatts. The Company's interests in three of
such plants are held by the Group. In addition, the Company owns an equity
investment in the Selkirk Plant.
   
  The Company is a participant in the highly competitive power generation
industry, which is among the largest industries in the United States, with an
estimated end-user market of over $200.0 billion of electricity sales and
annual net generation of approximately 3.5 million gigawatt hours. New
regulatory initiatives have been and are currently being adopted or considered
at the federal level and in approximately 45 states to increase competition in
the domestic power generation industry. In April 1996, FERC adopted Order No.
888, opening wholesale power sales to competition and providing for open and
fair electric transmission services by public utilities. At the state level,
industry restructuring is well advanced in various states including
California, Massachusetts, New York, New Jersey and Pennsylvania. This
restructuring includes deregulation of electric utilities and the introduction
of customer choice. The regulatory initiatives are expected to lead to the
transformation of the existing market, which is largely characterized by
electric utility monopolies, having old, inefficient, high-cost generating
facilities, selling to a captive customer base, to a more competitive market
where end users may purchase electricity from a variety of suppliers,
including non-utility generators, power marketers, public utilities and
others.     
 
  The Company believes that these market trends will present substantial
opportunities for industry participants that are efficient and low-cost power
producers and are able to offer competitive rates to customers. The Company
believes that an additional opportunity is presented by the significant
deregulation and consolidation now affecting the power industry, which has
resulted in substantial divestitures of generation assets by traditional power
utilities and by certain independent power producers currently owning
relatively few plants. For example, as a result of regulatory initiatives,
approximately 14,000 megawatts of New York generating capacity has been
announced for sale by utilities. Similar regulatory initiatives in New Jersey
and Pennsylvania are expected to cause utilities in those states to pursue
similar divestiture plans. At the same time, a number of industrial companies
have also announced plans to sell self-generation facilities and to re-deploy
the capital in their core businesses. These trends, which the Company believes
are likely to continue, should provide significant acquisition opportunities
for the Company.
   
  The Company also believes that attractive opportunities for development of
new generation assets will arise in the next few years, principally due to a
projected increase in baseload demand in the Northeast and Mid-Atlantic
regions and the retirement of a significant number of existing power
generation facilities which are 30 or more years old.     
 
  The Company's strategy is to maximize cash flow associated with its existing
plants and to grow through the expansion of the Company's existing operations
and through the acquisition and development of existing or new power
generation and related facilities. The Company intends to make capital
investments to assure the
 
                                      39
<PAGE>
 
ongoing efficiency of its existing plants and will pursue contractual and
operating changes which benefit such operations. In addition, the Company
believes that all three of the plants in which it has a substantial economic
interest are capable of being expanded, not only through additions to its
existing plants but also through the development and construction of new
facilities at the existing sites. The Company also believes the ongoing
changes in the industry will present ample opportunities for the acquisition
or development of new assets.
   
  To benefit the future results of operations of the Company by eliminating
the expense related to certain existing management services and gas management
services agreements and development bonuses, the McNair Interests and the
Minority Interests will provide the funding to terminate such agreements and
to "buy out" the development bonuses. In connection with the Formation
Transactions, Linden Venture and Camden Cogen will terminate management
services agreements with Linden Ltd. and Camden GPLP, respectively, and Linden
Venture, Camden Cogen and Selkirk LP will terminate gas management services
agreements with an individual who is one of the Minority Interests in
consideration of a termination fee to such individual. Linden Ltd., Camden
GPLP and Selkirk LP will terminate management services agreements with RCM
Management Services L.P. ("RCM"), a Delaware limited partnership that is
indirectly owned and controlled by Robert C. McNair. In consideration for the
termination of these agreements a termination fee will be paid to RCM.     
   
  To terminate such agreements, the McNair Interests and the Minority
Interests will make capital contributions, and Linden Venture, Camden Cogen
and Selkirk LP will make one-time payments totaling $83.9 million. Such
payments will be reflected in earnings in the period in which the payments are
made. Such payments will have no effect on the Group's liquidity or financial
condition since the amounts necessary to make such payments are being provided
by the shareholders and/or general and limited partners. The services
currently performed under such agreements will be assumed by existing Company
personnel.     
   
  In addition, one-time payments have been or will be made to "buy out"
development bonuses, which certain employees are eligible to receive in
subsequent periods. Such payments totaled $13.3 million in the first six
months of 1998 ($5.9 million in the second quarter of 1998) and additional
payments to be made prior to or in connection with the consummation of the
Formation Transactions are expected to total $14.9 million.     
   
  In July 1998, NJ Inc. acquired an additional indirect 5.25% partnership
interest in NJ Venture for $12.5 million in cash from an unaffiliated party.
On a pro forma basis, assuming the transaction took place on January 1, 1997,
such transaction would have increased the Group's equity in the earnings of NJ
Venture for the six months ended June 30, 1998 and the year ended December 31,
1997 by $1.3 million and $0.8 million, respectively, and the Group's net
income for such periods by $0.8 million and $0.5 million, respectively.

 Six Months Ended June 30, 1998 Compared to Six Months Ended June 30, 1997
       
  The Group's equity in the earnings of affiliates increased $17.3 million,
from $48.9 million in the first six months of 1997 to $66.2 million in the
first six months of 1998. The increase was attributable to a $14.9 million
increase in the Group's equity in the earnings of NJ Venture as well as
increases in its equity in the earnings of Camden Cogen and Linden Venture of
$0.8 million and $1.6 million, respectively.     
   
  NJ Venture's earnings increased $17.1 million primarily reflecting an $11.0
million increase in electricity revenues due to a $6.4 million fuel component
adjustment related to 1997 and 1996 operations and a higher rate for the
current period principally due to a higher fuel component. The fuel component
adjustment reflects an adjustment agreed to by the power purchaser in the
first quarter of 1998 based on an audit of the power purchaser's calculation
of the weighted average cost of gas for prior periods. NJ Venture's cost of
fuel was down $2.2 million compared to the first six months of 1997 and
operating and maintenance costs were down $0.8 million primarily reflecting
certain unplanned outage support costs in the first six months of 1997.
Depreciation expense was down $1.9 million reflecting the change in the
estimated useful life of the facilities which is discussed in Note 1 to the
combined financial statements of the NJ Partnerships for the first six months
of 1998, which are included elsewhere in the Prospectus. Interest income
increased $0.7 million reflecting interest on the previously discussed fuel
component adjustment.     
   
  Camden Cogen's earnings increased $2.6 million, primarily reflecting a $1.5
million decrease in depreciation expense due to the change in the estimated
life of the facilities as previously discussed. Camden Cogen's electricity
revenues were down $1.9 million but such decrease was offset by a $1.5 million
decrease in fuel costs. The Group's allocation of Camden Cogen's earnings
decreased by 16.9% compared to the first six months of 1997. The method of
allocation of the Partnership's earnings to the Group is discussed in Note 2
to the combined financial statements of the Group included elsewhere in this
Prospectus.     
   
  Linden Venture's earnings increased $4.6 million as a $9.8 million decrease
in revenues was offset by a $14.3 million decrease in costs. Electricity
revenues were lower primarily due to a lower fuel price component and a
limitation on the pass-through of fuel costs in the determination of
electricity sales prices. The method for determining the various components of
the electricity price received by the NJ Partnerships is discussed in
"Existing Venture and Plant Descriptions". Steam revenues were lower primarily
reflecting a lower fuel price component and lower steam take. Fuel costs
decreased $7.3 million reflecting lower prices and depreciation expense was
down $3.5 million due to the change in the estimated life of the facilities as
previously discussed.     
   
  Operating overhead increased from $7.5 million in the first six months of
1997 to $18.9 million in the first six months of 1998. Operating overhead in
the first six months of 1998 includes $13.3 million to "buy out" development
bonuses which certain employees were eligible to receive in subsequent
periods. Similar buy out transactions totaling $14.9 million will occur prior
to the Common Stock Offering. See "--General".     
   
  Earnings for the first six months of 1997 include a $7.4 million decrease in
a valuation allowance with respect to the realization of the receivable held
by Linden Ltd. from an affiliate, reflecting an increase in the value of the
investments held by such affiliate which comprise the primary resource of the
affiliate to settle its related payable.     
   
  Income taxes increased $4.2 million in the first six months of 1998
primarily reflecting the increase in earnings of NJ Venture.     
 
 Year Ended December 31, 1997 Compared to Year Ended December 31, 1996
   
  The Group's equity in the earnings of affiliates decreased $4.9 million,
from $111.5 million in 1996 to $106.6 million in 1997. The decrease was
primarily attributable to the impact of higher fuel costs at Linden Venture,
an overhaul at NJ Venture and a $4.5 million buyout of the prior contracts for
operation and maintenance services at all three plants. The Group's equity in
the earnings of Linden Venture, NJ Venture and     
 
                                      43
<PAGE>
 
Selkirk Cogen decreased $4.9 million, $0.6 million and $0.2 million,
respectively, and the Group's equity in the earnings of Camden Cogen increased
$0.8 million.
 
  NJ Venture's earnings decreased $0.7 million in 1997. Revenues increased
slightly primarily reflecting pass-through of a higher fuel cost factor;
however, costs and expenses included charges for $1.2 million to terminate its
operating and maintenance services agreement upon the change of contractors
and $2.5 million related to an overhaul of one of the plant's gas turbines.
 
  Camden Cogen's earnings increased $1.3 million in 1997. Revenues increased
$3.0 million primarily reflecting a higher capacity factor; however, costs and
expenses included charges for $1.4 million to terminate its operating and
maintenance services agreement to consolidate with one supplier. The
allocation of Camden Cogen's net income to the Group decreased by 3.3% in
1997.
 
  Linden Venture's earnings decreased $4.6 million, primarily reflecting lower
electricity revenues which were down $6.9 million due to the effect of a
limitation under the power purchase agreement on the pass-through of fuel
costs in the determination of electricity sales prices. Linden Venture's 1997
costs and expenses included a charge for $1.9 million to terminate its
operating and maintenance services agreement upon the change of contractors.
Taxes other than income taxes were down $1.1 million primarily reflecting
adjustments to amounts accrued in prior periods. The allocation of Linden
Venture's earnings to the Group was 1.5% lower than in 1996 as a result of
these factors.
 
  General and administrative costs of the Group increased $8.9 million from
$10.9 million in 1996 to $19.8 million in 1997, principally reflecting charges
for the use of corporate aircraft for a full year in 1997 ($8.6 million) and
an increased allocation of corporate overhead from an affiliate (see Note 4 to
the combined financial statements of the Group included elsewhere herein).
Additional overhead costs were allocated to the Group due to increased
management focus on the Group's operations in 1997.
 
  Interest and other income relates primarily to advances made by Linden Ltd.
to an affiliate which totaled $160.8 million at December 31, 1997. Interest
income related to such advances totaled $14.6 million in 1997 compared to
$15.6 million in 1996. This advance will be eliminated in the Formation
Transactions.
   
  Interest expense declined from $23.3 million in 1996 to $21.8 million in
1997, primarily reflecting lower outstanding long-term debt and fluctuations
in interest rates.     
 
  Earnings for 1997 include a $10.3 million reduction in a valuation allowance
with respect to the realization of the receivable held by Linden Ltd. from an
affiliate, reflecting an increase in the value of the investments held by such
affiliate which comprise the primary resource of the affiliate to settle its
related payable. Earnings for 1996 included a $10.3 million charge to increase
the valuation allowance with respect to the receivable.
 
 Year Ended December 31, 1996 Compared to Year Ended December 31, 1995
   
  The Group's equity in the earnings of affiliates increased $12.1 million,
from $99.4 million in 1995 to $111.5 million in 1996. The Group's equity in
the earnings of Linden Venture increased $19.7 million which more than offset
the $10.2 million decrease in the Group's equity in the earnings of NJ
Venture. The Group's equity in the earnings of Camden Cogen was up slightly in
1996.     
 
  NJ Venture's earnings decreased $11.7 million primarily reflecting an $11.8
million increase in fuel costs. Although fuel costs are a component in the
determination of NJ Venture's electricity sales prices, the costs which can be
passed through to the purchaser are limited by the purchaser's overall average
cost of fuel in a prior twelve-month period. In 1996 the amount of fuel costs
which NJ Venture was allowed to pass through was limited by this ceiling.
 
  Camden Cogen's earnings increased $0.8 million in 1996 reflecting slightly
higher gross margins and lower interest expense resulting from a lower loan
principal balance.
 
                                      44
<PAGE>
 
  Linden Venture's earnings increased $20.3 million due to higher operating
margins (gross margin less operating and maintenance) (up $21.6 million)
reflecting $6.4 million higher steam sales and lower operating and maintenance
costs due to a turbine overhaul in 1995. The allocation of Linden Venture's
net income to the Group was 5.8% higher in 1996 than in 1995.
 
  Other revenues increased from $0.8 million in 1995 to $2.3 million in 1996
reflecting an increase in the net premiums earned by CT Global.
 
  Operating overhead increased from $10.8 million in 1995 to $14.4 million in
1996 primarily reflecting a $2.5 million increase in net underwriting losses
incurred by CT Global.
 
  Interest income on Linden Ltd.'s advances to an affiliate totaled $15.6
million in 1996 compared to $16.8 million in 1995. Such advances totaled
$168.6 million at December 31, 1996.
   
  Interest expense declined from $26.4 million in 1995 to $23.3 million in
1996, primarily reflecting lower outstanding long-term debt and fluctuations
in interest rates.     
 
  Earnings for 1996 include a $10.3 million increase in a valuation allowance
with respect to the realization of the receivable held by Linden Ltd. from an
affiliate, reflecting a decrease in the value of the investments held by such
affiliate which comprise the primary resource of the affiliate to settle its
related payable. Earnings for 1995 included a $6.5 million credit to decrease
the valuation allowance with respect to the receivable.
 
 Year Ended December 31, 1995 Compared to Year Ended December 31, 1994
   
  The Group's equity in the earnings of affiliates increased $6.1 million,
from $93.3 million in 1994 to $99.4 million in 1995. Increases in the Group's
equity in the earnings of NJ Venture and Camden Cogen of $11.0 million and
$1.6 million, respectively, were partially offset by a decrease in the Group's
equity in the earnings of Linden Venture of $5.2 million. The Company's equity
in Selkirk Cogen was a $1.3 million loss in 1995.     
 
  NJ Venture's earnings increased $12.6 million with higher electricity
revenues (up $10.6 million) accounting for the majority of the increase, NJ
Venture's higher revenues primarily result from increased capacity in 1995
reflecting downtime in 1994 for major overhauls of all three gas turbines and
the steam turbine.
 
  Camden Cogen's earnings increased $1.7 million, primarily reflecting $1.3
million higher operating margins.
 
  Linden Venture's earnings decreased $5.4 million reflecting (i) lower
operating margins (down $2.6 million), and (ii) a $3.4 million business
interruption insurance settlement related to the 1993 failure of an electric
transformer which was included in 1994. The allocation to the Group of Linden
Venture's net income was 1.7% lower in 1995 than in 1994.
 
  Interest income on Linden Ltd.'s advances to an affiliate totaled $16.8
million in 1995 compared to $13.7 million in 1994. Such advances totaled
$185.8 million at December 31, 1995.
   
  Interest expense increased from $25.9 million in 1994 to $26.4 million in
1995, primarily reflecting fluctuations in interest rates partially offset by
lower outstanding long-term debt.     
 
  Earnings for 1995 include a $6.5 million reduction in a valuation allowance
with respect to the realization of the receivable held by Linden Ltd. from an
affiliate, reflecting an increase in the value of the investments held by such
affiliate which comprise the primary resource of the affiliate to settle its
related payable. Earnings for 1994 included a $6.5 million charge to increase
the valuation allowance with respect to the receivable.

LIQUIDITY AND CAPITAL RESOURCES
 
  To date the NJ Partnerships and the Group have obtained cash from their
operations, from nonrecourse project financing and from contributions from
limited and general partners and shareholders. This cash has been utilized to
develop and construct the cogeneration facilities, service debt, fund
operations and fund distributions to partners.
 
  The Company's long-term strategy is based in part on the expansion of
existing plants, development of new power plants and making selective
acquisitions. Continued access to capital with acceptable terms is necessary
to assure the success of this strategy. Project financing borrowings are
substantially non-recourse to the Company and are generally secured by the
physical assets, contracts and cash flows of the venture being financed.
Depending upon market conditions, the unique characteristics of the venture
and investor confidence in the Company, such funding may not be available or
the Company's traditional providers of project financing may seek higher
interest rates and increased equity participation. In addition to any project
financing loans, the Company would be required to provide a portion, if not
all, of the remaining long-term financing required to fund such expansions,
developments or acquisitions. Investments by the Company would likely take the
form of equity investments or loans which would be subordinated to any project
financing loans. The funds for such investments would have to be provided by
operating cash flow or long-term borrowings or through the issuance of
additional equity securities.
   
  The following table reflects sources and uses of cash for the NJ
Partnerships and the Group for the six months ended June 30, 1998 and 1997 and
the years ended December 31, 1997, 1996 and 1995:

</TABLE>    
 
  All of the Company's power purchase agreements are with large utilities
which presently have investment grade senior debt ratings. The Company's
principal power plants historically have provided a consistent and substantial
cash flow to equity holders due to the fixed payment components of the power
purchase contracts which have provided favorable margins over the ventures'
fixed operating and financing costs. Moreover, the variable energy payment
components of such agreements, which provide the second major component of
pricing under such agreements, have historically been well correlated to fuel
costs at the Bayonne and Camden Plants and have reflected a partial pass-
through mechanism for fuel expenses at the Linden Plant.

  NJ Venture has contracted to sell approximately 76% of its electrical
capacity to JCP&L pursuant to a 20-year power purchase agreement which expires
in 2008, with a ten-year renewal period subject to the approval of both
parties. The agreement establishes the sales price of the electricity based on
a fixed rate component plus factors for inflation and JCP&L's cost of natural
gas and retail sales prices. The remainder of NJ Venture's output is sold to
PSE&G pursuant to a 20-year power purchase agreement which expires in 2008,
with two five-year renewal periods subject to the approval of both parties.
The agreement provides for payments to NJ Venture consisting of a capacity
payment plus an energy payment which includes a fixed component plus factors
for inflation and fuel costs.
 
  Camden Cogen's electrical capacity is sold to PSE&G pursuant to a 20-year
power purchase agreement which expires in March 2013, with two five-year
renewal periods subject to the approval of both parties. The agreement
provides for payments to Camden Cogen consisting of a capacity payment plus an
energy payment which includes a fixed component plus factors for inflation and
fuel costs.
 
  Linden Venture sells its electrical capacity to Con Ed pursuant to a 25-year
power purchase agreement which expires in May 2017, with two five-year renewal
periods subject to the approval of both parties. The agreement establishes a
sales price of the electricity based primarily on capacity, fuel costs and
operating and maintenance costs.
   
  Selkirk Venture sells approximately 20% of its electrical capacity to
Niagara Mohawk Power Corporation ("Niagara Mohawk") under the terms of a
Master Restructuring Agreement ("NMMRA"). See "Existing Venture and Plant
Descriptions--Selkirk". Selkirk Venture has stated in its Report on Form 10-Q
for the period ended June 30, 1998, as filed with the Securities and Exchange
Commission (the "Commission"), that if Selkirk Venture and Niagara Mohawk
proceed to complete the transaction provided under the NMMRA, which completion
remains subject to a number of significant contingencies, management of
Selkirk Venture believes that, based on the facts and circumstances currently
known, and certain assumptions which such management believes to be
reasonable, an amended agreement is not expected to have a material adverse
effect on Selkirk Venture's future operating results and cash flows from
operations.     
 
  On August 1, 1990, Linden Venture entered into a steam sale agreement with
Exxon (the "Exxon Steam Sale Agreement") pursuant to which Linden Venture was
to sell steam to Exxon for use at Exxon's Bayway refinery and at certain other
facilities owned by Exxon in the area of the Bayway refinery. In 1993, Exxon
sold its Bayway refinery to Bayway, but retained the other facilities that
continued to use some of the steam originally covered by the Exxon Steam Sale
Agreement. The Exxon Steam Sale Agreement provided that Bayway, as the
purchaser of the refinery, would enter into a new steam sale agreement with
Linden Venture covering the sale of steam to Bayway by Linden Venture (the
"Bayway Steam Sale Agreement"), and that Exxon would enter into an amendment
to the Exxon Steam Sale Agreement to reflect the reduction in steam purchases
by Exxon (the "Amended Exxon Steam Sale Agreement" and, together with the
Bayway Steam Sale Agreement, the "New
 
                                      47
<PAGE>
 
Steam Sale Agreements"). Although the parties have been negotiating the New
Steam Sale Agreements, as of the date of this Prospectus, the New Steam Sale
Agreements have not been signed. Drafts of the New Steam Sale Agreements were
presented to the limited partner of Linden Venture for approval and the
limited partner, in turn, presented them to its lenders for approval, where
the matter now pends. The parties, in effect, have been operating as if the
New Steam Sale Agreements were in force, with Linden Venture selling steam to
each of Bayway and Exxon, and getting paid therefor by Bayway and Exxon,
respectively, pursuant to the terms of the unexecuted agreements. Although
Linden Venture is hopeful that these matters can be concluded soon and that
the New Steam Sale Agreements will be executed by the respective parties,
there can be no assurances in that regard.
 
  If Bayway were to cease purchasing steam from Linden Venture, the QF status
of the Linden Plant would be in jeopardy. See "Risk Factors--Risks Arising
from Utility Regulation and Deregulation". At the present, Linden Venture
believes that any risk relating to the status of its steam sale arrangements
is remote, because, among other things, it is the only steam supplier to the
area of the Exxon and Bayway facilities, and both Exxon and Bayway require
steam for their facilities.

  In February 1992, Camden GPLP entered into a $36.5 million Term Loan
Agreement (the "Camden GP Term Loan Agreement") with General Electric Capital
Corporation ("GECC") which matures in May 2010. Borrowings under the Camden GP
Term Loan Agreement, which totaled $14.8 million, bear interest at the London
Interbank Offering Rate ("LIBOR") plus 4.25% and are secured by Camden GPLP's
general partnership interest in Camden Cogen, Camden GPLP's general partner's
general partnership interest in Camden GPLP and certain reserve accounts
funded by revenues of Camden Venture. Principal payments are determined on a
quarterly basis and, together with interest, are payable monthly at varying
amounts in accordance with the terms of the Camden GP Term Loan Agreement. As
of June 30, 1998, the outstanding principal balance under the Camden GP Term
Loan Agreement was $12.7 million.

  In September 1992, Linden Ltd. entered into a $250.0 million Amended and
Restated Term Loan Agreement (the "Linden GP Term Loan Agreement") with State
Street Bank and Trust Company, as Trustee, which matures in September 2007 and
comprises a fixed rate portion, a floating rate portion and a working capital
   
portion. Under the terms of the Linden GP Term Loan Agreement the fixed rate
portion bears interest at 8.8%, the floating rate portion bears interest at
LIBOR plus 1.65% and the working capital portion bears interest at the one
month, financial commercial paper rate (as reported in Federal Statistical
Release H.15 (519) or successor publication) plus 0.55%. Borrowings under the
Linden GP Term Loan Agreement are secured by Linden Ltd.'s interest in Linden
Venture and certain reserve accounts funded with revenues of Linden Venture.
Principal and interest payments are made quarterly at varying amounts in
accordance with the terms of the Linden GP Term Loan Agreement. As of June 30,
1998, the outstanding principal balance under the Linden GP Term Loan
Agreement was $212.0 million.     
   
  Under the terms of a 1987 term loan agreement (the "Prudential Loan
Agreement") with The Prudential Insurance Company of America ("Prudential"),
NJ Venture had an outstanding principal balance of $69.8 million at June 30,
1998. The principal balance bears interest at 10.85% per annum and principal
and interest are payable quarterly through October 1, 2008, the maturity date
of the facility. All of NJ Venture's property, rights and interests are
pledged as collateral under the terms of the Prudential Loan Agreement.     
   
  Under the terms of a 1986 loan agreement (the "Equipment Loan Agreement")
with Bayonne Industries, Inc. ("Bayonne Equipment Lender"), NJ Venture has an
outstanding principal balance of $0.2 million at June 30, 1998 (with accrued
interest thereon in the additional amount of $0.2 million). The principal
balance and accrued interest are payable at the earlier of May 22, 1999 or the
execution of a new steam sale agreement. The principal balance bears interest
at the prime rate of First National Bank of Chicago plus 1%. The obligations
under the Equipment Loan Agreement are secured by the equipment purchased by
NJ Venture in connection with such agreement, and the payment of the interest
that has accrued and continues to accrue on the remaining principal balance is
non-recourse to NJ Venture.     
   
  NJ Venture has a $5.0 million revolving credit agreement with a bank to
satisfy short-term working capital requirements. At June 30, 1998 $1.5 million
was outstanding under such agreement, which expires in December 1998.
Principal amounts from time to time outstanding under the revolving credit
agreement accrue interest at 0.5% below the bank's prime rate and, together
with all other amounts from time to time owing under the agreement, are
secured by NJ Venture's rights to payment under its power purchase agreements.
In addition, NJ Venture also has an outstanding letter of credit to secure
certain obligations to PSE&G Company ("PSE&G"). The letter of credit was
procured for NJ Venture by Cogen Technologies Financial Services L.P.
("Financial Services"), an entity owned by the McNair Interests and the
Minority Interests that is not part of the Company. NJ Venture pays a
quarterly fee on such letter of credit calculated at 0.3% per annum on the
face amount of the letter of credit to the issuer thereof. Financial Services
has the reimbursement obligations to such issuer in the event any drawing is
made on the letter of credit. Pursuant to agreement between NJ Venture and
Financial Services, NJ Venture agrees to reimburse Financial Services for all
fees and reimbursement obligations incurred by Financial Services under the
letter of credit, which obligations of NJ Venture are unsecured. As of June
30, 1998 the outstanding amount of such letter of credit was $4.6 million. The
letter of credit expires in May 1999, and its reimbursement obligation is
secured by the assets of an affiliate.     
 
  In April 1993, Camden Cogen entered into a $119.0 million Amendment and
Restatement of Construction and Term Loan Agreement (the "Camden Cogen Term
Loan Agreement") with GECC, to obtain term financing for the loans incurred by
Camden Cogen to develop and construct the Camden Plant. The Camden Cogen Term
Loan Agreement initially provided for a senior tranche A loan (the "Camden
Tranche A Loan") and two subordinated tranche loans: a tranche B subordinated
loan (the "Camden Tranche B Loan") and a tranche C subordinated loan (the
"Camden Tranche C Loan"). The Camden Tranche A Loan is with a group of banks
and bears interest at rates which increase over the term of the agreement from
1.0% to 1.625% above the three-month LIBOR rate (1.25% for the period November
3, 1998 to November 1, 2001). Principal and interest are payable quarterly
through May 1, 2007, the maturity date of the Camden Tranche A Loan. Camden
Cogen has entered into an interest rate swap agreement with GECC which
effectively fixes Camden Cogen's LIBOR rate on the Camden Tranche A Loan at
5.945%. The swap agreement has a notional amount equal at all times to the
 
                                      49
<PAGE>
 
   
outstanding principal balance of the Camden Tranche A Loan. The effect of the
swap on Camden Cogen's interest expense for the six months ended June 30, 1998
and 1997 and the years ended December 31, 1997, 1996 and 1995 was to increase
(decrease) such expense by $0.1 million, $0.1 million, $0.2 million, $0.3
million and $(0.1) million, respectively. The "fair value" of the swap, $0.6
million at December 31, 1997, is discussed in Note 6 to the Combined Financial
Statements of the NJ Partnerships, included elsewhere herein. The Camden
Tranche B Loan is with GECC and bears interest at 11.4% with principal and
interest payable quarterly through May 1, 2009, the maturity date of the
Camden Tranche B Loan. The Camden Tranche C Loan has been repaid in full with
the proceeds of an equity contribution by its holder, GECC, in an amount equal
to the amount outstanding under such loan.     
   
  GECC provides a letter of credit for Camden Cogen to secure certain
obligations under the Camden Tranche A Loan, for which it pays no fees. As of
June 30, 1998 such letter of credit was in the outstanding amount of $4.8
million. The letter of credit expires in May 2007, and its reimbursement
obligation is secured by the Camden Plant and other assets and revenues of
Camden Cogen.     
   
  GECC provides a $10.0 million letter of credit for Linden Venture to secure
certain obligations with one of its purchasers, for which it pays a fee equal
to 0.75% per annum on the aggregate outstanding face amounts. The $10.0
million letter of credit expires in August 1999, and in accordance with its
terms, is expected to be renewed on an annual basis in the amount of $10.0
million. The reimbursement obligations under the letters of credit are
unsecured.     
 
  The security and reserve accounts established by the above term and credit
facilities effectively provide the respective debt holders a mechanism for
repayment (scheduled, accelerated or otherwise), prior to funds from any
venture becoming available for distribution to the Company. Similarly, each of
the Linden Venture and Camden Cogen partnership agreements provides for a
predetermined monthly amount of distributable cash from Linden Venture and
Camden Cogen revenues, respectively, to be set aside for preferential
distributions to the respective limited partners of Linden Venture and Camden
Cogen, in each case prior to distributions to the respective general partners
of Linden Venture and Camden Cogen, each of which is a wholly-owned subsidiary
of the Company. In the case of Linden Venture, the predetermined monthly
amount is capped at 99% of varying amounts ranging from approximately $4.3
million per month through September 1998, approximately $3.0 million per month
from October 1998 through September 2001, and approximately $4.3 million to
$4.8 million per month thereafter. In the case of Camden Cogen, the
predetermined monthly amount is equal to 99% of the Camden Cogen Distributable
Cash (as defined herein) up to a monthly capped amount (such capped amount
being approximately $0.3 million to $0.4 million through May 2007 and varying
amounts thereafter).
   
LITIGATION     
   
  Six plaintiffs, individually on behalf of themselves and as representatives
of a class of persons similarly situated, filed an environmental lawsuit in
Louisiana state court against 92 defendants, including McNair Transport, Inc.
(predecessor to MESC). In the lawsuit, plaintiffs allege that defendants
caused environmental contamination at two sites in Iberville Parish,
Louisiana. Plaintiffs, who are alleged to have worked at the sites or resided
near the sites, claim personal injuries, increased risk and fear of future
disease, and property damage. Plaintiffs seek actual and exemplary damages of
an unspecified amount.     
   
  Defendants removed the case to federal court, and the lawsuit is currently
pending in the United States District Court for the Middle District of
Louisiana. Defendants' motion to deny class certification is pending before
the court, and discovery on the merits of the case has, therefore, not
formally begun. MESC, the successor by merger to McNair Transport, Inc., is
unable at this time to evaluate the merits of the plaintiffs' claims, if any,
or to estimate potential costs or liability.     
   
  There are certain other claims and legal actions pending against the Group
and its equity investees. While the outcome of such proceedings cannot be
predicted with certainty, management does not expect these matters to have a
material adverse effect on the financial condition or results of operations of
the Group.

DIVIDENDS
 
  As a newly formed entity, Cogen has not paid any dividends. Because of the
nature of the Company's business, however, and the cash flow expected by the
Company from the operation of the independent power plants in which it has
interests, as described elsewhere in this Prospectus, the Company expects that
for the foreseeable future a substantial part of its earnings will be paid in
dividends to its stockholders. While there can be no assurance that earnings
will be available for distribution or that such dividends actually will be
distributed or that they will be continued at any particular level for any
particular period of time, the Company expects to pay annual dividends for the
foreseeable future on the Common Stock at the rate of $      per share per
quarter. The declaration of dividends is at the discretion of the Company's
Board of Directors and will be subject to the terms of the Company's debt
agreements, including the Indenture, concerning restricted payments. The
Company's dividend policy will be reviewed by the Board of Directors at such
future time as may be appropriate in light of relevant factors at that time.
During the initial years of the Company's operations, dividends with respect
to the Common Stock are expected to exceed the share of the current and
accumulated earnings and profits of the Company allocable to the holders of
the Common Stock (as determined for United States federal income tax
purposes). In such a case, such excess generally would be treated as a tax-
free return of capital up to a holder's basis in such holder's shares of
Common Stock and as capital gain thereafter. Any such excess would not be
eligible for the dividends-received deduction generally available with respect
to dividends paid to corporate holders of the Common Stock. To the extent a
holder receives dividends that constitute a return of capital to such holder,
the holder's basis in the shares upon which dividends are paid will be
reduced. See "Certain United States Federal Income Tax Consequences--U.S.
Holders--Sale or Other Disposition of Company Stock".) No assurance can be
given, however, that such distributions will in fact exceed the Company's
current and accumulated earnings and profits for such purposes or, if any such
distributions are made, regarding the amount of any such excess. See "Certain
United States Federal Income Tax Consequences--U.S. Holders--Dividends". The
Company's ability to pay dividends will, in any event, always be dependent
upon cash flow received from distributions to it by its subsidiaries, which
are in turn dependent upon distributions from the ventures. As described
elsewhere in this Prospectus, the ventures in which the Company has an
interest and obtains its cash flow are subject to restrictions with respect to
distributions to their holders of equity. See "Description of Senior Notes and
Certain Other Indebtedness--Plant Project Financings".
 
YEAR 2000 COMPLIANCE
 
  To ensure that the Company's computer systems are Year 2000 compliant, the
Company has been reviewing each of its financial and operating systems to
identify those that contain two-digit year codes. All of the Company's
financial and business systems have been reviewed and all necessary equipment
and software upgrades have been identified and are expected to be in place by
mid-1999.
 
  At the plants operated by the NJ Partnerships, GE, the operations and
maintenance contractor, is coordinating all Year 2000 issues with plant
equipment manufacturers and software suppliers. The NJ Partnerships have
contacted the owners of the plant interconnects (electric, gas and water) and
the electric power purchasers, requesting the status of their Year 2000
programs. To date there have been no significant items identified and all
investigations are expected to be complete by the end of 1998 with all
compliance issues resolved by mid-1999.
 
  Based upon current information, the Company does not anticipate costs
associated with the Year 2000 issue to have a material financial impact.
However, there can be no assurances that there will not be interruptions or
other limitations of financial and operating systems functionality or that the
Company will not incur significant costs to avoid such interruptions or
limitations. The costs incurred relating to the Year 2000 issue will be
expensed during the period in which they are incurred. The Company's
expectations about future costs associated with the Year 2000 issue are
subject to uncertainties that could cause actual results to have a greater
financial impact than currently anticipated. Factors that could influence the
amount and timing of future costs include the success of the Company in
identifying systems and programs that contain two-digit year codes, the nature
and amount of programming required to upgrade or replace each of the affected
programs and the rate and magnitude of related labor and consulting costs.

proceedings that result from the ordinary conduct of its business. For
information regarding two pending proceedings, see Note 6 to the Group's
Audited Combined Financial Statements and Note 3 to NJ Partnerships' Unaudited
Combined Financial Statements. While the outcome of any of these proceedings
cannot be predicted with certainty, the Company does not expect these matters
to have a material adverse effect on the financial condition or results of
operations of the Company.

                    EXISTING VENTURE AND PLANT DESCRIPTIONS
 
  The Company's Linden Plant is a 715 megawatt dispatchable, gas-fired,
combined-cycle cogeneration facility located inside the Bayway refinery
facility in Linden, New Jersey. The Linden Plant commenced commercial
operations in May 1992 and currently sells 645 megawatts of its electric
capacity and energy to Con Ed under an original term, 25-year power purchase
agreement. Linden Venture sells the Linden Plant's steam to Bayway and Exxon
Corporation. See "--Linden Steam Sales Agreement". The Bayonne Plant is a 176
megawatt base load, gas-fired, combined-cycle cogeneration facility located
inside the IMTT facility in Bayonne, New Jersey. The Bayonne Plant commenced
commercial operations in October 1988 and sells approximately 76% of its
electric capacity and energy to JCP&L and approximately 24% of its electric
capacity and energy to PSE&G under separate original term 20-year power
purchase agreements. Bayonne sells its steam to IMTT-Bayonne and IMTT-BX under
two separate year-to-year steam supply agreements. The Camden Plant is a 146
megawatt base load, gas-fired, combined-cycle cogeneration facility located in
Camden, New Jersey. The Camden Plant commenced commercial operations in March
1993 and sells all of its electric capacity and energy to PSE&G under an
original term 20-year power purchase agreement. Camden sells its steam to
Camden Paperboard Company ("Camden Paperboard") under an original term 20-year
steam supply agreement.

LINDEN OWNERSHIP STRUCTURE     
 
  The Linden Plant is owned by Linden Venture, a limited partnership. The
general partner of Linden Venture, Linden Ltd., is a limited partnership owned
and controlled indirectly by the Company. The limited partner in Linden
Venture is an owner trust in which GECC and Dana have equity interests (the
"Owner Trust"), a trust created for the benefit of GECC and its co-investors.
See "--Security Structure". The beneficial owner of the Owner Trust is a
general partnership (the "Owner Partnership") whose partners are special
purpose corporations wholly owned by GECC and Dana, respectively. For a chart
showing, in a simplified manner, the Linden ownership structure, see
"Prospectus Summary--Formation".
   
  The following chart sets forth, in a simplified manner, the ownership
structure of Linden Venture prior to the consummation of the Formation
Transactions.     
 
                             [CHART APPEARS HERE]

 
LINDEN FINANCING STRUCTURE
 
  The development and construction of the Linden Plant were financed through
September 1992 equity contributions of $25.0 million from Linden Ltd. and
$500.0 million from the Owner Trust. In return for its $500.0 million equity
capital contribution, the Owner Trust received a limited partnership interest
in Linden Venture. The proceeds of the equity contributions were used by
Linden Venture to repay its construction loan. As a result of its equity
contribution, the Owner Trust receives distributions from Linden Venture on a
preferential basis. See "--Linden Cash Distributions" and "Description of
Senior Notes and Certain Other Indebtedness--Plant Project Financings".
 
LINDEN GENERAL PARTNER TERM LOAN
   
  Pursuant to the Linden GP Term Loan Agreement, the Owner Trust also made a
$250.0 million term loan facility available to Linden Ltd. (the "Linden GP
Term Loan"). The Linden GP Term Loan is secured by Linden Ltd.'s general
partnership interest in Linden Venture and certain reserve accounts funded
with revenues of Linden Venture. See "--Linden Cash Distributions". Linden
Ltd. must use $10.0 million of the proceeds of the Linden GP Term Loan as
working capital for Linden Venture. An amount of $25.0 million of the Linden
GP Term Loan was used to fund Linden Ltd.'s equity contributions in Linden
Venture. The balance of the proceeds of the Linden GP Term Loan was loaned by
Linden Ltd. to Financial Services. See "Certain Transactions--Formation
Transactions". No further borrowings may be made by Linden Ltd. under the
Linden GP Term Loan, and at June 30, 1998, its outstanding principal balance
was $212.0 million. The Linden GP Term Loan matures in September, 2007. See
"Description of Senior Notes and Certain Other Indebtedness--Plant Project
Financings--Linden Venture".

LINDEN CASH DISTRIBUTIONS
 
  The cash remaining after payment of taxes, operating expenses and
maintenance of required reserve funds ("Linden Venture Distributable Cash") is
distributed monthly by Linden Venture to the partners of Linden Venture. In
addition, distributions of Linden Venture Distributable Cash to Linden Ltd.
are to be made (i) net of monthly (a) principal and interest debt service
requirements under the Linden GP Term Loan Agreement and (b) amounts required
to maintain ratios (the "Required Payment Ratios"), for specified periods,
based upon (y) total Linden Venture Distributable Cash, together with the
amount of earnings on the working capital fund and interest paid by Linden
Venture on working capital loans from Linden Ltd., for such period to (z)
Linden Venture Distributable Cash made to Linden Ltd. under Tranche 1 (as such
term is hereinafter defined), together with debt service payments of Linden
Ltd. on the Linden GP Term Loans, for the same period, and (ii) in the absence
of a default under the Linden GP Term Loan Agreement. The Required Payment
Ratios are calculated with respect to quarterly periods and, in certain
instances, annual periods, with such quarterly-calculated ratios ranging from
1.1 to 1.0 and 1.2 to 1.1, and such annual-calculated ratios being either 1.1
to 1.0 or 1.2 to 1.0.
   
  There are three tranches of payments under the Linden Venture partnership
agreement. The Owner Trust, as the limited partner in Linden Venture, receives
the first 99% of Linden Venture Distributable Cash up to a capped amount equal
to approximately $4.3 million per month through September 1998, approximately
$3.0 million per month from October 1998 through September 2001 and between
$4.3 million and $4.8 million per month thereafter ("Tranche 1"). Tranche 1
distributions are set at a level that, over a period of 22.5 years, will repay
the Owner Trust an amount equal to its initial equity investment plus an 8.4%
return thereon (including the allocation of venture tax benefits).     
   
  The amount of Tranche 1 payments determines the amount of two other
tranches. Tranche 2 is the Linden Venture Distributable Cash remaining after
the Tranche 1 payment, up to an amount equal to twice the amount of Tranche 1.
Tranche 2 distributions are allocated 99% to Linden Ltd. and 1% to the Owner
Trust. Tranche 3 is the remaining Linden Venture Distributable Cash in excess
of Tranches 1 and 2 and is distributed 10% to the Owner Trust and 90% to
Linden Ltd. Payments under each tranche must be made in full before any
payments on the next tranche may be made. The distribution of cash according
to the terms summarized above will be in effect until the date (the "Flip
Date") which is the earlier of 22.5 years or the date upon which the Owner
Trust has achieved an 8.4% return on its initial equity investment (the
"Implicit Rate of Return"). On the Flip Date, distribution of cash according
to the above mechanism ends, and all Linden Venture Distributable Cash will be
distributed initially 30% to the Owner Trust and 70% to Linden Ltd. until the
achievement by the Owner Trust of a 6.4% after-tax rate of return (the
"Minimum Return"), at which time the Owner Trust's distributable percentage
will be reduced to 20%. After the Minimum Return has been achieved, the Owner
Trust's distributable percentage will be reduced to 10% and finally to 1% when
the Owner Trust has achieved after-tax rates of return of 7.4% and 8.4%,
respectively.

Notes and Certain Other Indebtedness--Plant Project Financings--Linden
Venture" and the Combined Statements of Cash Flows of the Group.     
 
LINDEN PLANT DESCRIPTION
 
  The Linden Plant is a 715 MW gas-fired, combined-cycle cogeneration
dispatchable facility developed by an affiliate of the Company and owned by
Linden Venture (while the subject is a highly technical one, combined-cycle
technology is believed by the Company to be the most advanced technically
available for fossil fuel fired power plants because it maximizes the use of
all energy produced from the combustion of the fuel). The Linden Plant is
located in Linden, New Jersey, on the site of the Bayway Refinery facility,
which is owned by Bayway, and adjacent to a chemical plant complex and
technology center owned by Exxon just south of Newark Airport. Electricity
generated by the Linden Plant is sold to Con Ed, and steam is sold to Exxon
and Bayway.
 
  The Linden Plant was constructed by Ebasco Constructors, Inc. and achieved
commercial operations in May 1992. While maintaining 100% steam availability
to meet the steam customers' demands, the Linden Plant's overall equivalent
capacity factor for electrical production has been in excess of 93% for each
full operating year since it entered service, with the exception of 1993 when
the equivalent capacity factor fell to 86% due to a main transformer failure
in April of that year. The Linden Plant's average equivalent capacity factor
for the period from the commercial operations date to December 1997 has been
93%. For 1997, its equivalent capacity factor was 96%.
 
  The Linden Plant comprises five GE Frame 7EA gas turbine generators and
three GE condensing steam turbine generators. Natural gas is burned directly
in the gas turbine generators to produce electricity and high temperature
exhaust gases. The exhaust gases from the gas turbines are channeled into five
Nooter Eriksen Heat Recovery Steam Generators ("HRSG") to produce high
pressure steam for the steam turbine generators. The steam turbine generators
produce additional electricity and process steam which is sold to Exxon and
Bayway.
 
  The steam turbines, in turn, exhaust into a multi-cell air cooled condenser
to return condensate to the plant's water cycle. The condensate produced by
the air cooled condenser reduces the plant's water consumption by roughly 66%.
Condensate from process steam sold to Bayway and Exxon is not returned to the
cycle. All raw makeup water is purchased from Elizabethtown Water Company.
 
 
                                      56
<PAGE>
 
  The 13.8 kilovolt ("KV") electrical power produced by the generators is
stepped up to 345 KV. The SF6 gas insulated switch gear then delivers the
electricity to an underground, parallel connected pair of oil-filled cable
ducts, which provide the outgoing power connection directly to Con Ed,
allowing the plant to be treated as an "in-city" facility, which the Company
believes generally adds value to its capacity from a reliability standpoint.
This electric interconnection terminates with Con Ed's Goethals Station on
Staten Island, New York, after passing through a cable tunnel bored through
bedrock under the Bayway Refinery and the Arthur Kill waterway. The total
interconnection distance to Con Ed is approximately 1.6 miles. Each cable has
transmission capacity of 650 MW with the addition of heat exchangers, which if
engaged, would provide enough capacity to handle the entire output of the
plant, thereby providing more than full backup transmission capacity for the
Linden Plant or possible additional transmission capacity to support an
expansion at the facility if one were to be undertaken.
 
  The Linden Plant has been designed, and is being maintained and operated, to
meet the strict environmental standards of the State of New Jersey. The Linden
Plant uses Best Available Control Technology ("BACT"), and is being operated
and maintained, to reduce gas turbine, water and noise emissions to the levels
required and permitted by federal and state regulators. Nitrogen oxide ("NOx")
emissions levels are controlled through steam injection into the turbine
combustion chambers and selective catalytic reduction ("SCR") in the HRSGs.
Carbon monoxide ("CO") emissions are controlled by the design of the
combustion turbines.
 
  The thermal cycle and plant design have been designed to operate 8,760 hours
per year at 93% availability, with design net delivered capacity of 645 MW and
export steam generation volume of 582,000 lbs/hour.
 
LINDEN POWER PURCHASE AGREEMENT
 
  Linden Venture sells 645 MW of the Linden Plant's electrical capacity to Con
Ed pursuant to a 25-year power purchase agreement, dated April 14, 1989 and
amended September 17, 1990 and December 22, 1993 (the "Linden PPA"). The
Linden PPA has been structured to minimize the impact of adverse changes in
fuel costs or operating levels and the loss of QF status on project economics.
Certain provisions of the Linden PPA are summarized below.
 
  Term: Base term of 25 years from the date of commercial operations, May
1992, with two automatic five-year renewal periods but with the option of
either party to give to the other party notice of non-renewal.
 
  Regulatory Approval: Subject only to initial approval by the New York Public
Service Commission ("NYPSC"). Provisional NYPSC authorization occurred
September 1989, allowing Con Ed full recovery of all payments for the purchase
of electricity under the Linden PPA through its fuel adjustment clause. Final
NYPSC approval occurred in 1991.
 
  Base Term Pricing--Capacity: Con Ed is required to pay a fixed capacity rate
of 1.8553c per KWh "delivered", where "delivered" means actual or available,
subject to a cap of 85% of the Linden Plant's dependable maximum net
capability. KWh "delivered" in excess of the 85% cap during the 12 months
preceding any off-peak months can be credited to any off-peak month in which
the 85% cap is not reached.
 
  Base Term Pricing--Fuel: Con Ed is obligated under the Linden PPA to pay
actual fuel costs, including steam commodity, transportation and storage
costs. The fuel component is subject to an annual cap of 2.634c per KWh
purchased, adjusted for changes in Con Ed's annual weighted average cost of
gas since 1989. Actual fuel costs below the annual cap entitle the Linden
Plant to an incentive payment of 50% of the difference. Actual fuel costs
above the annual cap must be absorbed 100% by Linden Venture.
   
  Base Term Pricing--O&M: Con Ed is required to pay an escalating operating
and maintenance ("O&M") rate of 0.9c per KWh at contract inception (1.2357c
per KWh in June 1998), increasing by a local CPI inflation factor on a monthly
basis. This rate is paid for KWh "delivered", subject to a cap of 90% of the
Linden Plant's dependable maximum net capability. A credit mechanism similar
to capacity payments exists pursuant to which     
 
                                      57
<PAGE>
 
KWh "delivered" in excess of the 90% cap during the 12 months preceding any
off-peak months can be credited to any off-peak month in which the 90% cap is
not reached.
 
  Security: The tracking account under the Linden PPA tracks the difference
between payments Con Ed has made to Linden Venture under the Linden PPA to
estimated Con Ed long run Avoided Costs at the time the Linden PPA was signed.
Such tracking account reached a maximum of $111 million in July 1996 and
declined to zero in July 1998 pursuant to the terms of the Linden PPA.
 
  Operation--Curtailment: Con Ed is permitted to reduce the dispatch of the
plant by various amounts in certain periods for the first 15 years of the
Linden PPA. Upon four hours notice, Con Ed may reduce actual deliveries to 82%
of dependable maximum net capability. Upon 12 hours notice, Con Ed may reduce
actual deliveries to the 82% limit less 150 MW for 8 hours on weekday nights a
maximum of 100 times a year. Upon 24 hour notice, Con Ed may reduce actual
deliveries to 47% of dependable maximum net capability on weekends and certain
holidays. In the last 10 years of the base term Con Ed has the right, upon 24
hours notice, to reduce the dispatch of the plant to 47% on a continuous basis
with limited rights to cycle the plants to higher loads. Con Ed's obligations
to pay capacity and O&M charges are unaltered by curtailment and,
consequently, the Linden Plant's financial performance is largely unaffected
by curtailment by Con Ed.
 
  Operation--Voltage: The Linden Plant will supply voltage support within a
specified range as requested by Con Ed, via direct interconnection at Con Ed's
Goethals substation on Staten Island, New York.
 
  Qualifying Facility Status: During any period in which the Linden Plant
ceases, temporarily or permanently, to be a QF, Con Ed's rates will be reduced
10%.
 
  Breach of Contract: Among other events, failure by the Linden Plant to use
good faith efforts to resume deliveries after an outage of 120 days
constitutes a breach under the Linden PPA. Failure to perform for reasons of
force majeure is not deemed a breach.
 
  Insurance: Under the Linden PPA, Linden Venture is required to maintain
customary insurance coverages.
 
  Assignment: The Linden PPA may not be assigned or transferred by either
party without prior written consent of the other party except that Linden
Venture may assign to an affiliate or a lender and may also assign under
certain conditions, such as a sale of the facility.
 
  Force Majeure: Either party to the Linden PPA may suspend performance
(except for any obligation to make payments) thereunder due to the occurrence
of force majeure so long as the non-performing party provides notice to the
other party within 14 days of becoming aware of the force majeure event and
endeavors to remedy its inability to perform.
 
LINDEN STEAM SALES AGREEMENT
 
  Linden Venture sells steam to both Exxon and Bayway. On August 1, 1990,
Linden Venture entered into the Exxon Steam Sale Agreement pursuant to which
Linden Venture was to sell steam to Exxon for use at Exxon's Bayway refinery
and at certain other facilities owned by Exxon in the area of the Bayway
refinery. In 1993, Exxon sold its Bayway refinery to Bayway, but retained the
other facilities that continued to use some of the steam originally covered by
the Exxon Steam Sale Agreement. The Exxon Steam Sale Agreement provided that
Bayway, as the purchaser of the refinery, would enter into the Bayway Steam
Sale Agreement with Linden Venture covering the sale of steam to Bayway by
Linden Venture, and that Exxon would enter into the Amended Exxon Steam Sale
Agreement to reflect the reduction in steam purchases by Exxon. Although the
parties have been negotiating the New Steam Sale Agreements, as of the date of
this Prospectus, the New Steam Sale Agreements have not been signed. Drafts of
the New Steam Sale Agreements were presented to the limited partner of Linden
Venture for approval and the limited partner, in turn, presented them to its
lenders for approval, where the matter now pends. The parties, in effect, have
been operating as if the New Steam Sale Agreements were in force, with Linden
Venture selling steam to each of Bayway and Exxon, and getting paid therefor
by
 
                                      58
<PAGE>
 
Bayway and Exxon, respectively, pursuant to the terms of the unexecuted
agreements. Although Linden Venture is hopeful that these matters can be
concluded soon and that the New Steam Sale Agreements will be executed by the
respective parties, there can be no assurances in that regard.
 
  If Bayway were to cease purchasing steam from Linden Venture, the QF status
of the Linden Plant would be in jeopardy. See "Risk Factors--Risks Arising
from Utility Regulation and Deregulation". At the present, Linden Venture
believes that any risk relating to the status of its steam sale arrangements
is remote, because, among other things, it is the only steam supplier to the
area of the Exxon and Bayway facilities, and both Exxon and Bayway require
steam for their facilities.
 
LINDEN GAS SERVICE AGREEMENTS
 
  Linden Venture entered into a Gas Service Agreement in July 1990 with PSE&G
and Elizabethtown Gas (the "suppliers"), providing for transportation and
partial supply being furnished jointly, with PSE&G supplying 80% and
Elizabethtown Gas the balance. Linden Venture currently has short-term gas
supply agreements with Anadarko Energy Services Company, Columbia Energy
Services Corp., Engage Energy U.S. L.P., Sonat Marketing Company, Vastar Gas
Marketing, Inc. and Texaco Natural Gas Inc. Certain provisions of the Gas
Service Agreement are summarized below.
 
  Term: Base term of 25 years. Sales service may be terminated after 15 years,
but if not renewed, will be replaced by a transportation resale service.
 
  Quantities: The minimum quantity of gas under the agreement is 73,000
decatherms/day ("Dth/day"). The maximum quantity is 143,500 Dth/day. The base
amount of 85,000 Dth/day is subject to full interruption up to a maximum
number of days per year during certain peak days (defined by temperature).
Beyond the maximum number of days interruption limit, gas can be curtailed to
the 73,000 Dth/day minimum. Butane storage and deliverability are sized to
supply the minimum fuel requirements during gas supply interruptions but
during such interruptions, the plant can be operated on Butane at an output
level of only 300 MW due to butane deliverability restrictions.
 
  Obligations: Linden Venture must contract for a year-round supply of natural
gas of 85,000 Dth/day plus line loss and compressor fuel. Such supply will be
firm from December through March, and will be contractually committed for by
the preceding June 1. The Linden Plant must purchase and make available to the
suppliers certain quantities (specified in the contract) of butane storage and
butane product for use by the suppliers on peak days during the period
November through March. The suppliers must obtain at least 15 years firm
transportation capacity and obtain interruptible transportation as necessary.
 
  Services: Under resale service, Linden Venture will purchase gas supply in
the U.S. Gulf Coast production areas from which the suppliers have pipeline
transportation capacity. Linden Venture will deliver to the pipeline receipt
points of the suppliers in the production area 85,000 Dth/day, plus line loss
and compressor fuel, selling such amount to the suppliers at those locations.
Suppliers will then resell these amounts, less line loss and compressor fuel,
to Linden Venture at the plant's interconnections with the suppliers'
facilities. Resale service volumes will be at least the minimum quantity. FERC
Order 636, issued April 1992, prohibits new contracts for such resale
transportation services. This contract is allowed under the grandfather
provision of Order 636, but it cannot be extended or renewed. Subject to
nominations by Linden Venture, the suppliers sell Linden Venture gas from
their system supply in an amount that can range from zero to 58,500 Dth/day.
Butane also is purchased by Linden Venture from the Bayway Refinery for use as
back-up fuel if the suppliers fail to deliver natural gas.
 
  Pricing: Resale service is priced in three components: (i) a component based
on the plant's commodity price as initially sold to the suppliers at their
receipt points; (ii) a component based on transportation costs; and (iii) a
component based on a specified service fee which can escalate. Sales service
is priced separately for peak and off-peak service. Off-peak supply is priced
in three components: (i) a component based on a cost formula; (ii) a component
allowing for shrinkage and line loss; and (iii) a component based on a
specified service fee which
 
                                      59
<PAGE>
 
can escalate with the suppliers' base rates. Peak sales service during the
months of December through March above a specified level includes a price
component based on storage costs.
   
  Force Majeure: The Gas Service Agreement may be terminated by the suppliers
for lack of performance by Linden Venture due to occurrence of force majeure
if the inability to perform extends for a certain specified period of time.
This period of time can be extended if certain fees are paid to the suppliers
by Linden Venture. The Gas Service Agreement may be terminated by Linden
Venture if the suppliers experience a force majeure event that extends for a
certain specified period of time.     
 
LINDEN OPERATION AND MAINTENANCE ARRANGEMENTS
 
  Linden Venture has entered into an Operation and Maintenance Agreement dated
effective as of June 6, 1997 (the "Linden O&M Agreement"), with GE, replacing
an operation and maintenance agreement with another party in order to achieve
economies of scale by having a single operator for all three plants and to
make more consistent the operation and maintenance of the Company's three
operated plants. The initial term of the Linden O&M Agreement is 12 project
years, with Linden Venture having the right to terminate upon payment of a
specified amount at the end of each of the fourth, seventh and tenth project
years and to extend for an additional two years. Thereafter, the Linden O&M
Agreement is extended automatically each year, unless either Linden Venture or
GE gives 12 months' notice of termination. The Linden O&M Agreement is a "cost
reimbursable" contract with a monthly operator's fee and with performance
bonuses payable to GE and liquidated damages assessed against GE based on a
series of performance criteria negotiated with GE and set forth in the terms
of the Linden O&M Agreement. In 1997, Linden Venture paid performance bonuses
of $0.1 million, but no operator's fees were required to be paid in the first
partial year of the Linden O&M Agreement under the terms thereof. Pursuant to
the terms of the Linden O&M Agreement, the Company expects that operator fees
will be paid in future years. Under the Linden O&M Agreement, Linden Venture
is obligated to buy all parts and services needed at the Linden Plant from GE
at certain discount prices, and GE is obligated to furnish such parts and
services to the Linden Plant; provided that if GE is unable to provide such
parts or services in a timely or cost effective manner, Linden Venture may
obtain such parts and services from alternative sources.
 
LINDEN INSURANCE ARRANGEMENTS
 
  Linden Venture carries insurance consisting of:
 
 .  ""All Risk" property insurance for direct damage from non-excluded perils
   including but not limited to fire and extended coverage, vandalism, theft,
   collapse, flood, and earthquake. Such coverage is required to be written on
   a replacement cost basis.
 
 .  Comprehensive boiler and machinery insurance for sudden or accidental
   breakdown of mechanical or electrical equipment.
 
 .  ""Single Interest Excess of Loss Policy" insurance is maintained above the
   coverage of property and boiler machinery policies.
 
 .  Business interruption insurance covering loss of net profits and continuing
   expenses resulting from physical loss or damage at the Linden Plant subject
   to a 30-day deductible.
 
 .  General liability insurance and excess liability insurance.
 
 .  Workers' compensation and employers' liability insurance.
 
LINDEN ENVIRONMENTAL MATTERS
 
  Linden Venture has established, and incorporates, environmental awareness
and resource conservation standards in its day-to-day activities. These
standards are guiding principles for Linden Venture, its employees and the
operation of the Linden Plant, reflecting a commitment to environmentally
sound engineering and long-term values.
 
                                      60
<PAGE>
 
  Waste water, consisting primarily of boiler blowdown and demineralized rinse
water, is processed with temperature and acidity ("pH") monitored and
controlled prior to discharge into the Linden Roselle Sewer Authority.
Sanitary waste is also discharged into the Linden Roselle Sewer Authority.
Site runoff water is collected and monitored for pH prior to being discharged
to the Arthur Kill waterway. Air emissions from the facility are controlled
and reduced through steam injection, SCR and turbine design, with all
emissions well below permitted limits. Noise emissions are significantly lower
than required standards. The Company has solid waste disposal arrangements
with contractors it believes to be legally and financially responsible.
 
LINDEN SITE LEASE AGREEMENT
 
  Linden Venture and Exxon entered into a ground lease agreement dated as of
August 1, 1990 (the "Site Lease") with respect to the Linden Plant site within
Exxon's industrial complex (the "Site"). When Exxon sold its refinery to
Bayway, it assigned to Bayway the ground lease agreement. There are various
default provisions in the Site Lease that are triggered by the default
provisions of the Exxon Steam Sale Agreement. Bayway, as a successor to Exxon
under the Site Lease, is entitled to terminate the Site Lease in the event
Linden Venture defaults under the Exxon Steam Sale Agreement (subject to
various protections in favor of Linden Venture) but is not entitled to
terminate the Site Lease if Bayway is in default under the Exxon Steam Sale
Agreement. The Site Lease provides Linden Venture with both a leasehold estate
in the Site and non-exclusive easements over other portions of Bayway's
property for various interconnections to the Linden Plant.
 
  The term of the Site Lease is 25 years from initial commercial operations of
the Linden Plant, followed by two 5-year renewal terms and additional
extensions if desired by the parties. Base rent is $383,000/year, adjusted by
CPI.
 
LINDEN SECURITY STRUCTURE
 
  The Company understands that the assets of the Owner Trust consist of its
limited partnership interest in Linden Venture and the Linden GP Term Loan.
The indebtedness of Linden Ltd. to the Owner Trust, as lender under the Linden
GP Term Loan, is secured by a pledge of Linden Ltd.'s general partnership
interest in Linden Venture and certain reserve accounts funded with the
revenue of Linden Venture. See "--Linden Cash Distributions". Because of its
equity financing structure, Linden Venture has no long-term debt on its
balance sheet and is unencumbered by any liens on its assets. While there is
no indebtedness on Linden Venture's balance sheet, Linden Venture's
partnership agreement contains certain provisions that effectively restrict
Linden Venture from, among other things, entering into certain agreements or
commitments, selling or otherwise transferring assets, incurring indebtedness
(other than defined permitted indebtedness), creating or allowing any lien on
its property (other than defined permitted liens) and amending or modifying
project documents without the consent of the limited partner of Linden
Venture, which is the Owner Trust.

BAYONNE OWNERSHIP STRUCTURE
 
  The Bayonne Plant is owned by NJ Venture, a general partnership. The
managing general partner of NJ Venture is NJ Inc., a subsidiary of the
Company, which owns, directly or indirectly, 91.75% of the interests in NJ
Venture. The other general partners of NJ Venture are parties unrelated to the
Company.
   
  The following chart sets forth, in a simplified manner, the ownership
structure of NJ Venture prior to the consummation of the Formation
Transactions.

 Formation Transactions.     
 
BAYONNE FINANCING STRUCTURE
   
  Pursuant to the Prudential Loan Agreement, the development and construction
of the Bayonne Plant was financed through a $90.0 million term loan (the
"Prudential Term Loan") provided by Prudential and approximately $30.0 million
in equity contributed by the partners of NJ Venture. The Prudential Term Loan
is non-recourse to the partners of NJ Venture (except in certain limited
circumstances), is secured by all revenues and assets of NJ Venture and
matures in October 2008. At June 30, 1998, the outstanding principal balance
of the Prudential Term Loan was $69.8 million. See "Description of Senior
Notes and Certain Other Indebtedness--Plant Project Financings--NJ Venture".
       
  In addition, under the terms of the Equipment Loan Agreement with the
Bayonne Industries, Inc., and as of June 30, 1998, NJ Venture is indebted to
the Bayonne Equipment Lender for the principal amount of $0.2 million and an
additional amount for accrued interest of $0.2 million. Such outstanding
principal amount and accrued interest thereon is due at the earlier of May 22,
1999 or the execution of a new steam sale agreement. The obligations under the
Equipment Loan Agreement are secured by the equipment purchased by NJ Venture
in connection with such agreement, and the payment of the interest that has
accrued and continues to accrue on the remaining principal balance is non
recourse to NJ Venture, it being limited to the security for the loan.     
   
  Pursuant to a Revolving Credit Loan Agreement (the "Revolving Facility")
with Southwest Bank of Texas, N.A. ("SBT"), NJ Venture established a working
capital revolving facility in the maximum available amount of $5.0 million,
which facility is secured by revenues of NJ Venture and expires December 18,
1998. In addition, NJ Venture has an outstanding letter of credit issued by
the Union Bank of Switzerland ("UBS") to secure certain obligations to PSE&G
(the "PSE&G L/C"), which expires in May 1999 and its reimbursement obligation
is secured by the assets of an affiliate. The letter of credit was procured
for NJ Venture by Financial Services. NJ Venture pays a quarterly fee on such
letter of credit calculated at 0.3% per annum on the face amount of the     
 
                                      62
<PAGE>
 
   
letter of credit to the issuer thereof. Financial Services has the
reimbursement obligations to such issuer in the event any drawing is made on
the letter of credit. Pursuant to agreement between NJ Venture and Financial
Services, NJ Venture agrees to reimburse Financial Services for all fees and
reimbursement obligations incurred by Financial Services under the letter of
credit, which obligations of NJ Venture are unsecured. At June 30, 1998, $1.5
million was outstanding under the Revolving Facility, and the outstanding
amount of the PSE&G L/C was $4.6 million. See "Description of Senior Notes and
Certain Other Indebtedness--Plant Project Financings--NJ Venture".     
 
NJ VENTURE CASH DISTRIBUTIONS
 
  The cash remaining after payment of operating expenses, debt service and
maintenance of required reserve funds ("NJ Venture Distributable Cash") is
distributed monthly by NJ Venture to each of the partners of NJ Venture
according to each partner's respective ownership percentages in NJ Venture.
Under the Prudential Term Loan Agreement, NJ Venture is prohibited from making
distributions to its partners except in accordance with an approved operating
budget, and no distributions may be made if there is a default under the
Prudential Term Loan Agreement. In addition, the Prudential Term Loan
Agreement requires NJ Venture to create a debt service reserve fund from net
cash flow if NJ Venture's annual debt service ratio, calculated each quarter
using the previous twelve months financial information, falls below 1.50x. NJ
Venture must increase the reserve until funds held in such reserve plus the
funds available for debt service equals 1.50x the previous twelve months debt
service. Any funds held in such reserve may be released as cash to the extent
that the balance of funds retained in such reserve (if any) together with NJ
Venture's net cash flow cause NJ Venture's coverage ratio to exceed 1.50x.
There are similar restraints on distributions in the Revolving Facility.
Historical distributions of NJ Venture are set forth in the table below.

BAYONNE PLANT
 
  The Bayonne Plant is a 176 MW gas-fired, combined-cycle cogeneration
facility developed by a subsidiary of the Company that owns NJ Venture. The
Bayonne Plant is located on the site of the IMTT facility in Bayonne, New
Jersey. Power generated by the Bayonne Plant is sold 75.8% to JCP&L and 24.2%
to PSE&G, with steam sold to IMTT-Bayonne and IMTT-BX.
 
  The Bayonne Plant was constructed by GE and achieved commercial operations
in October 1988. The Bayonne Plant is a base load facility with a rated net
capacity of 165 MW. The Bayonne Plant's availability and capacity factors have
been in excess of 91% and 88%, respectively, for each full operating year
since the plant entered service (except in 1994 when the capacity factor was
85% due to the performance of major overhauls on all of the gas turbines). The
Bayonne Plant's average availability and capacity factors for the period from
the commercial operations date to December 1997 were 92% and 90%,
respectively. For 1997, the Bayonne Plant's availability and capacity factors
were 94% and 92%, respectively.
 
  The Bayonne Plant comprises three GE Frame 6B gas turbine generators and one
GE Single Admission/Extraction Condensing ("SAEC") steam turbine generator.
Natural gas is burned directly in a combustion turbine generator to produce
electricity and high temperature exhaust gases. The exhaust gases from the gas
turbines are channeled into three Henry Vogt HRSGs to produce high pressure
steam for a steam turbine driven electric generator, providing additional
electricity as well as extracting quality process steam for sale to
 
                                      63
<PAGE>
 
IMTT-Bayonne and IMTT-BX. The steam turbine exhausts into a water cooled
surface condenser to return condensate to the Bayonne Plant's water cycle. All
raw makeup water is purchased from the City of Bayonne pursuant to an
agreement that provides for the City of Bayonne to supply to the Bayonne Plant
1.5 million gallons per day of potable water. The agreement expires June 1,
2018.
 
  The 13.8 KV electrical power produced by the generators is stepped up to 138
KV and delivered by SF6 switchgear to an underground cable which provides the
outgoing power connection to PSE&G. This cable interconnects with PSE&G's
Bayonne Substation in Bayonne, New Jersey, over an interconnection distance of
approximately three miles.
 
  The Bayonne Plant has been designed, and is being maintained and operated,
to meet the strict environmental standards of the State of New Jersey and uses
BACT to reduce gas turbine, water and noise emissions to the levels required
and permitted by federal and state regulators. NOx emissions levels are
controlled by water injection into the gas turbine combustion chambers and by
SCR in the waste heat recovery boilers. CO emissions are controlled by design
of the combustion turbines.
 
  The plant has been designed based on a thermal cycle power output of 165 MW
net and average export steam generation of 125,000 lbs/hour.
 
NJ VENTURE POWER PURCHASE AGREEMENT--JCP&L
 
  NJ Venture sells 75.8% of the Bayonne Plant's net electrical output (up to
an average annual maximum of 125 MW) to JCP&L, under a power purchase
agreement (the "JCP&L PPA"), dated October 29, 1985, as amended September 5,
1986 and August 1, 1988. Certain provisions of the JCP&L PPA are summarized
below.
 
  Term: Base term of 20 years with a 10-year automatic renewal period subject
to the agreement of both parties.
 
  Regulatory Approval: Approval of the JCP&L PPA by the New Jersey Board of
Public Utilities ("NJBPU"), which was required for the JCP&L PPA to be
effective, was received December 16, 1985, and approval of the contract
amendment, which required NJBPU approval, was obtained on December 8, 1986.
 
  Base Term Pricing--Applicable Rate: The Applicable Rate is the sum of the
Fixed, Gas, GNP Deflator and Retail Rate components (as defined below). The
JCP&L PPA requires that JCP&L pay 120% of the Applicable Rate for all
electricity delivered during on-peak periods and 88.9% of the Applicable Rate
for off-peak periods. Peak period is 8:00 am to 8:00 pm, Monday through
Friday, 52 weeks per year.
 
  Base Term Pricing--Fixed: JCP&L is required to pay a fixed component of
2.80c/KWh for electricity delivered to receipt points up to a maximum
aggregate of 125 MW/hour on the average annual basis.
   
  Base Term Pricing--Gas: JCP&L pays a gas component which is indexed against
changes in JCP&L's weighted average cost of gas. The gas component is
3.63c/KWh as of June 30, 1998 for power delivered to receipt points up to a
maximum aggregate of 125 MW/hour on the average annual basis.     
   
  Base Term Pricing--GNP Deflator: JCP&L is required to pay a general price
change component, which reflects inflation adjustments and was as of June 30,
1998 approximately 0.965c/KWh, for power delivered to receipt points up to a
maximum aggregate of 125 MW/hour on the average annual basis.     
   
  Base Term Pricing--Retail Rate: JCP&L is required to pay a local price
change component which reflects changes in JCP&L's retail rates and was as of
June 30, 1998 approximately 0.841c/KWh, for power delivered to receipt points
up to a maximum aggregate of 125 MW/hour on the average annual basis.     
 
  Curtailment: JCP&L may curtail purchases only in the event of force majeure
and other excusable conditions including: (i) an emergency involving the
wheeling system and (ii) interruptions, curtailments and
 
                                      64
<PAGE>
 
reductions required by prudent electrical practices. It is not anticipated
that these limited curtailment provisions will have a material effect on NJ
Venture's revenues under the JCP&L PPA. JCP&L has not curtailed power
purchases to date.
 
  Breach of Contract: Among other events, failure of the Bayonne Plant to
deliver electricity for 365 consecutive days, for reasons other than force
majeure, constitutes a breach.
 
  Assignment: The JCP&L PPA may not be assigned or transferred by either party
without written consent.
 
  Force Majeure: Either party to the JCP&L PPA may suspend performance (except
for any obligation to make payments) thereunder due to the occurrence of force
majeure so long as the non-performing party provides prompt notice to the
other party of the force majeure event and expeditiously takes action to
continue performance, remedy the event excusing performance and mitigate
resulting damages to the other party.
 
NJ VENTURE POWER PURCHASE AGREEMENT--PSE&G
 
  The remaining 24.2% of electrical output (approximately 40 MW) of the
Bayonne Plant is sold to PSE&G pursuant to an extendible Power Purchase and
Operations Coordination Agreement ("PSE&G PPA"), dated June 5, 1989. The PSE&G
PPA provides for the sale of energy and capacity from the Bayonne Plant to
PSE&G. Under the PSE&G PPA, PSE&G makes seasonal capacity payments and base
monthly energy payments consisting of a fixed component, a fuel component and
an inflation component. Certain provisions of this agreement are summarized
below.
 
  Term: Base term of 20 years with two five-year renewal options, subject to
mutual agreement of both parties.
 
  Regulatory Approval: Requires approval of the NJBPU, which must find the
contract reasonable and prudent throughout its term, and which must allow
PSE&G full and timely recovery of contract costs through the utility's energy
clause. NJBPU authorization occurred June 1989.
   
  Base Term Pricing--Capacity: PSE&G is required to pay a monthly seasonal
capacity payment for power delivered to PSE&G's receipt point. The payment is
$8.76/KW per month, from January 1, 1988, escalated at 4.9% per annum; the
rate as of June 30, 1998 was $13.47 per KW. Payments during certain periods
will not exceed established capacity levels as follows: during summer peak
months of June through September, the Bayonne Plant has a nominated capacity
of 36 MW, and during the winter peak months of December through February, the
plant has a nominated capacity of 43 MW. NJ Venture has the right to adjust
these seasonal capacity levels within a range of plus or minus 10% every year.
    
  PSE&G is obligated to pay an energy charge which has three components:
fixed, energy fuel and energy inflation, each as described below:
 
  Base Term Pricing--Fixed: The fixed energy component is 2.0c/KWh for power
delivered to PSE&G's receipt point and remains unchanged for twenty years.
   
  Base Term Pricing--Energy Fuel: The fuel energy component was initially
1.88c/KWh for power delivered to PSE&G's receipt point escalating monthly at
PSE&G's Cogeneration Interruptible Gas Rate Schedule ("CIG") as approved by
NJBPU. The CIG rate is based on PSE&G's average cost of gas and also includes
an additional component representing transportation through the local
distribution system. The fuel energy component rate was 2.09c/KWh as of June
30, 1998.     
 
  Base Term Pricing--Energy Inflation: On December 1, 1988, the inflation
component was 0.72c/KWh for power delivered to PSE&G's receipt point. The
inflation component escalates based on a Gross Domestic Product ("GDP") index
on January 1st of each succeeding year beginning on January 1, 1990. This
component
 
                                      65
<PAGE>
 
   
tracks closely with a portion of the plant's pipeline charges and variable O&M
payments, which tend to increase with inflation. The inflation component was
0.93c/KWh as of June 30, 1998.     
   
  Security: There is a tracking account which tracks the difference between
payments PSE&G has made to NJ Venture under the PSE&G PPA to estimated future
capacity and energy rates of the Pennsylvania, New Jersey and Maryland
Interchange ("PJM"), a close power pool consisting of certain utilities
located in the Mid-Atlantic States. These estimates are fixed and set out in
the PSE&G PPA. The tracking account will reach a maximum of $46 million during
1998 and will decline to zero by 2005. If a breach by PSE&G were to result in
a termination of the PSE&G PPA, NJ Venture would be required to pay to PSE&G
the amount, if any, by which the balance in the tracking account exceeds the
liquidated damages due NJ Venture as a result of such breach. NJ Venture has
provided a letter of credit to PSE&G for 10% of the tracking account ($4.6
million at June 30, 1998) to secure its contingent obligation with respect to
the security provisions of the PSE&G PPA.     
 
  Operation Curtailment: PSE&G is obligated to accept up to a maximum of 24.2%
of the Bayonne Plant's net electrical output unless: (i) the plant fails to
comply with safety requirements, (ii) such acceptance would jeopardize the
integrity or transmission facilities of the PSE&G or PJM systems, (iii) during
system emergencies or planned maintenance of the transmission or
interconnection facilities, or (iv) during light load periods, if due to
operational circumstances, PSE&G would incur costs greater than those that it
would have incurred if it had not made such purchases. PSE&G has not invoked
any of the provisions set out in clauses (i), (ii) and (iii) above through
1997, but has curtailed the Bayonne Plant pursuant to the "light load"
provisions.
 
  Qualifying Facility Status: The Bayonne Plant must meet FERC's operating and
efficiency standards to maintain its QF status under PURPA. If sections 201
and 210 of PURPA are no longer in effect or the Bayonne Plant ceases to
qualify as a QF for reasons not within its control, including, a reduction or
cessation in thermal energy use, the PSE&G PPA will nevertheless continue in
effect, provided (i) the NJBPU does not bar PSE&G from passing the rates
through to its customers, (ii) federal, state or local laws are not violated,
and (iii) NJ Venture or its owners are not subject to unreasonable burdensome
regulation under PUHCA. See "Government Regulation--Federal Energy
Regulation". If one of the above events does occur, NJ Venture and PSE&G must
negotiate in good faith for an arrangement with substantially similar economic
benefits to each party under the PSE&G PPA. In addition, if one of the above
PURPA events occurs, and the NJBPU denies rate pass-through of PSE&G's
obligations under the PSE&G PPA, NJ Venture and PSE&G must negotiate in good
faith to provide a rate with substantially similar economic benefits to each
party, and which the NJBPU will permit PSE&G to recover from its ratepayers.
If a final non-appealable order is issued that the Bayonne Plant is not a QF,
then either party may terminate the PSE&G PPA, unless the Bayonne Plant is
attempting to restore its QF status.
 
  Breach of Contract: Failure by NJ Venture to perform its obligations under
the contract constitutes a breach unless within 30 days after notice from
PSE&G such venture cures the breach or commences and diligently pursues a
cure.
 
  Insurance: NJ Venture is required to maintain customary insurance coverages.
 
  Assignment: The PSE&G PPA may not be assigned or transferred by either party
without prior written consent of the other party except NJ Venture may assign
it to an affiliate or lender.
 
  Force Majeure: Either party to the PSE&G PPA may suspend performance (except
for any obligation to make payments) thereunder due to the occurrence of force
majeure so long as the non-performing party provides prompt notice to the
other party of the force majeure event and expeditiously takes action to
remedy the event excusing performance.
 
BAYONNE TRANSMISSION SERVICE AND INTERCONNECTION AGREEMENT
 
  NJ Venture and PSE&G entered into a revised transmission service and
interconnection agreement (the "Transmission and Interconnection Agreement")
on April 27, 1987, under which PSE&G agreed to design,
 
                                      66
<PAGE>
 
construct, own and operate a 138 KV underground transmission cable circuit and
associated terminal facilities (jointly the "Interconnection") to connect the
Bayonne Plant with PSE&G's Public Service System at PSE&G's Bayonne Switching
Station. The electric power transmission facilities of PSE&G are
interconnected with those of JCP&L, and both PSE&G and JCP&L are members of
the PJM Interconnection. The initial term of the agreement is 20 years. Upon
the expiration of the initial term, the Transmission and Interconnection
Agreement shall automatically be extended for a succeeding term of 10 years,
unless either party elects, upon three years' notice, to terminate the
Transmission and Interconnection Agreement at the close of the initial term.
 
BAYONNE AGREEMENT FOR THE SALE OF STEAM AND ELECTRICITY TO IMTT-BAYONNE
 
  NJ Venture entered into an agreement for the sale of steam and electricity
(as amended, the "IMTT Steam Sale Agreement") with IMTT-Bayonne on June 13,
1985, which was amended on May 22, 1986. The IMTT Steam Sale Agreement
provides for the sale to IMTT-Bayonne of 100% of its steam needs at its tank
terminal facility, and at the venture's option, the sale of electricity. NJ
Venture has no current plans to offer IMTT-Bayonne electricity under the IMTT
Steam Sale Agreement. The IMTT Steam Sale Agreement has a base term of 10
years, which has expired, with automatic renewal thereafter for each following
year unless either party elects to terminate the agreement at the end of a
renewal year upon 60 days notice. IMTT-Bayonne agrees to purchase from NJ
Venture all of the thermal energy requirements of its tank terminal facility
up to the deemed maximum steam production of 57,000 lbs/hour according to a
pricing formula based on IMTT-Bayonne's avoided cost of steam.
 
BAYONNE AGREEMENT FOR THE SALE OF STEAM TO IMTT-BX (FORMERLY EXXON)
 
  NJ Venture and Exxon entered into an Agreement for the Sale of Steam (the
"Exxon Steam Sale Agreement") on February 27, 1987, which was amended on
August 21, 1988. Under the terms of the Exxon Steam Sale Agreement, Exxon
agreed to purchase from the Bayonne Plant an average of 50,000 lbs/hour of
steam on an annualized basis. The Exxon Steam Sale Agreement provides for an
initial term of five years (now expired). Thereafter, the Exxon Steam Sale
Agreement continues on a year to year basis unless either party exercises its
rights to terminate as provided in the Exxon Steam Sale Agreement. Beginning
in the fifth year of the agreement, either party is entitled to serve written
notice on the other of its intent to terminate the agreement. The Exxon Steam
Sale Agreement would then terminate one year after the notice or at an earlier
date upon which the parties mutually agree. Exxon used the steam at its
adjacent terminal facility (the "Exxon Terminal Facility") for industrial
purposes.
 
  Exxon sold its terminal facility in Bayonne to IMTT-BX on April 1, 1993. As
a result, IMTT-BX assumed Exxon's rights and obligations under the Exxon Steam
Sale Agreement and is currently performing under the agreement (hereafter
referred to as the "IMTT-BX Steam Sale Agreement"). IMTT-BX renamed the Exxon
Terminal Facility IMTT-BX.
 
BAYONNE GAS SUPPLY ARRANGEMENTS
 
  NJ Venture currently purchases its natural gas requirements from PSE&G
pursuant to provisions of a CIG. The Bayonne Plant requires approximately
13,140,000 MMBtu/year (an average of 36,000 MMBtu/day). Certain provisions of
the agreement are summarized below.
 
  Term: Base term of one year with automatic renewals subject to termination
upon five days notice.
 
  Quantities: NJ Venture will purchase up to a maximum of 3,000 Dth/hour and
up to a maximum of 17,600,000 Dth/year.
 
  Obligations: The Bayonne Plant shall maintain QF status.
 
 
                                      67
<PAGE>
 
  Service: Interruptible service shall be provided by PSE&G under certain
conditions that include (i) PSE&G's continuing ability to provide the service,
and (ii) the Bayonne Plant's continuing status as a QF. The Bayonne Plant's
supply is subject to 100% interruption on eight hours notice.
 
  Pricing: NJ Venture is required to pay a monthly charge per MMBtu of gas
equal to the sum of
 
 .  PSE&G's estimated average commodity cost of gas,
 
 .  PSE&G's interstate pipeline commodity charges,
 
 .  50% of PSE&G's interstate pipeline demand charges, and
 
 .  PSE&G's local distribution charge.
 
  The average price of gas under CIG in 1997 was $3.496 per MMBtu.
 
  In the event that PSE&G does interrupt service, the Bayonne Plant could
utilize kerosene, which is stored at the site in a day tank with a capacity of
250,000 gallons. In addition, the Bayonne Plant has approximately 60,000
barrels (equivalent to approximately 10 days' supply at full output) of
storage under lease from IMTT--Bayonne adjacent to the site with direct
pipeline transfer capability to the Bayonne Plant's day tank. Additional fuel
is stored routinely by fuel suppliers at the IMTT--Bayonne terminal facility.
Over the last four winters, the Bayonne Plant's gas supply has been
interrupted a total of ten days. During those periods of interruption, the
plant continued to operate on kerosene.
 
BAYONNE OPERATION AND MAINTENANCE ARRANGEMENTS
 
  GE operates and maintains the Bayonne Plant pursuant to an operations and
maintenance agreement dated effective as of June 6, 1997 (the "Bayonne O&M
Agreement"). The initial term of the Bayonne O&M Agreement expires on November
1, 2008. NJ Venture has a right to terminate the Bayonne O&M Agreement upon
the payment of specified amounts at the end of each of the fourth, seventh and
tenth project years. The Bayonne O&M Agreement is a "cost reimbursable"
contract with a monthly operator's fee and with performance bonuses payable to
GE and liquidated damages assessed against GE based on a series of performance
criteria negotiated with GE and set forth in the Bayonne O&M Agreement. In
1997, Bayonne paid performance bonuses to GE of $0.1 million, but no
operator's fees were required to be paid in the first partial year of the
Bayonne O&M Agreement under the terms thereof. Pursuant to the terms of the
Linden O&M Agreement, the Company expects that operator fees will be paid in
future years. Under the Bayonne O&M Agreement, the Bayonne Plant is obligated
to buy all parts and services needed at the Bayonne Plant from GE at certain
discount prices, and GE is obligated to furnish such parts and services to the
plant; provided that if GE is unable to provide such parts or services in a
timely or cost effective manner, the venture may obtain such parts and
services from alternative sources.
 
BAYONNE INSURANCE ARRANGEMENTS
 
  NJ Venture carries insurance consisting of:
 
 .  ""All Risk" property insurance for direct damage from non-excluded perils
   including but not limited to fire and extended coverage, vandalism, theft,
   collapse, flood, and earthquake. Such coverage is required to be written on
   a replacement cost basis.
 
 .  Comprehensive boiler and machinery insurance for sudden or accidental
   breakdown of mechanical or electrical equipment.
 
 .  Business interruption insurance covering loss of net profits and continuing
   expenses, including debt service, resulting from physical loss or damage at
   the Bayonne Plant subject to a 30-day deductible.
 
 .  General liability insurance and excess liability insurance.
 
 .  Workers' compensation and employers' liability insurance.
 
                                      68

BAYONNE ENVIRONMENTAL
 
  Waste water, consisting primarily of boiler and cooling tower blowdown,
storm water, demineralizer rinse water and site runoff water, is processed and
the temperature and pH are monitored and controlled prior to discharge into
the Kill Van Kull. Sanitary waste is discharged to the Bayonne Municipal sewer
authority. Air emissions from the facility are controlled and reduced through
water injection into the turbine combustion chambers, SCR and turbine design,
with all emissions below permitted limits. Noise emissions are lower than
required standards. The Company has solid waste disposal arrangements with
contractors it believes to be legally and financially responsible.
 
BAYONNE SITE LEASE AGREEMENT
 
  NJ Venture, IMTT-Bayonne and Bayonne Industries, Inc. ("Bayonne Industries")
entered into a ground lease agreement dated as of May 26, 1986 (the "Bayonne
Site Lease") with respect to the Bayonne Plant site within the IMTT-Bayonne
facility (the "Bayonne Site"). The Bayonne Site Lease provides NJ Venture with
both a leasehold estate in the Bayonne Site and non-exclusive easements over
other portions of Bayonne Industries' property for various interconnections to
the Bayonne Plant.
 
  The initial term of the Bayonne Site Lease is 20 years from the date of the
Bayonne Site Lease. The Bayonne Site Lease will automatically renew after
expiration of the initial term, for two succeeding terms, the first for two
years and the second for 10 years, unless NJ Venture elects to terminate the
lease. Base rent for the Bayonne Plant is pre-paid for 20 years.
 
CAMDEN OWNERSHIP STRUCTURE
 
  The Camden Plant is owned by Camden Cogen, a limited partnership. The
general partner of Camden Cogen, Camden GPLP, is a limited partnership
subsidiary of the Company. The limited partner in Camden Cogen is GECC.
   
  The following chart sets forth, in a simplified manner, the ownership
structure of Camden Cogen prior to the consummation of the Formation
Transactions.     
 
 
                             [CHART APPEARS HERE]

 
CAMDEN FINANCING STRUCTURE
 
  Pursuant to the Camden Cogen Term Loan Agreement, the development and
construction of the Camden Plant was initially financed through a $132.0
million loan. On April 1, 1993 (the "Second Capital Contribution
 
                                      69
<PAGE>
 
Date"), and pursuant to the Camden Cogen Term Loan Agreement, such loan was
refinanced as a term facility to provide for 3 tranches of term loans payable
to GECC: the Camden Tranche A Loan of $81.6 million, the Camden Tranche B Loan
of $27.2 million and the Camden Tranche C Loan of $10.2 million; the remaining
balance of the construction loan was contributed to Camden Cogen as equity by
GECC. Subsequently, on December 22, 1993, GECC assigned the Camden Tranche A
Loan to The Bank of Tokyo--Mitsubishi Trust Company and Toronto Dominion
(Texas) Inc., GECC retained the Camden Tranche B Loan, and GECC also
contributed an amount equal to the amount represented by the Camden Tranche C
Loan as additional equity in Camden Cogen for payment in full by Camden Cogen
of the Camden Tranche C Loan.
   
  The Camden Tranche A Loan and the Camden Tranche B Loan (collectively, the
"Camden Cogen Term Loans") are secured by a lien on the Camden Plant, Camden
Cogen's revenues and other assets, a pledge of the partnership interest of
Camden GPLP, and a pledge of Camden GPLP's general partner's general
partnership interest in Camden GPLP. The Camden Tranche A Loan matures May 1,
2007, and at June 30, 1998, the aggregate outstanding principal balance of the
Camden Tranche A Loan was $63.9 million. The Camden Tranche B Loan matures May
1, 2009, and at June 30, 1998, the outstanding principal balance of the Camden
Tranche B Loan was $23.6 million. See "Description of Senior Notes and Certain
Other Indebtedness--Plant Project Financings--Camden Cogen". In addition,
pursuant to the Camden Cogen Term Loan Agreement, GECC has issued for the
account of Camden Cogen, a standby letter of credit for the benefit of the
holders of the Camden Tranche A Loan in an amount representing six months debt
service on that loan, which amount at June 30, 1998 was $4.8 million. See
"Description of Senior Notes and Certain Other Indebtedness--Plant Project
Financings--Camden Cogen".     
 
CAMDEN GENERAL PARTNER TERM LOAN
   
  Pursuant to the Camden GP Term Loan Agreement, GECC has made available a
$36.5 million term loan facility to Camden GPLP (the "Camden GP Term Loan")
secured by Camden GPLP's general partnership interest in Camden Cogen, the
general partnership interest in Camden GPLP of its general partner and certain
reserve accounts created with revenues of Camden Cogen. No further borrowings
may be made by Camden GPLP under the Camden GP Term Loan, and at June 30,
1998, the outstanding principal balance of the Camden GP Term Loan was $12.7
million. The Camden GP Term Loan matures in May 2010. See "Description of
Senior Notes and Certain Other Indebtedness--Plant Project Financings--Camden
Cogen".     
 
CAMDEN CASH DISTRIBUTIONS
 
  Camden Cogen's cash ("Camden Cogen Distributable Cash") remaining after the
payment of project expenses and, pursuant to the security deposit agreement
entered into in connection with the Camden Cogen Term Loan Agreement, monthly
transfers from revenues of Camden Cogen for (i) fees and expenses owed to
lenders, interest rate swap counterparties and letter of credit issuers under
the Camden Cogen Term Loan Agreement, (ii) principal interest rate and
interest debt service for lenders under the Camden Cogen Term Loan Agreement,
(iii) reimbursement obligations owed on letters of credit issued under the
Camden Cogen Term Loan Agreement and (iv) reserve amounts required if the
fixed charge coverage ratio of the Camden Cogen Term Loan Agreement is less
than 1.2 to 1.0, is, absent the existence of a default under the Camden Cogen
Term Loan Agreement, distributed monthly by Camden Cogen to the partners of
Camden Cogen. In addition, distributions of Camden Cogen Distributable Cash to
Camden GPLP are to be made (a) net of monthly (1) principal and interest debt
service requirements under the Camden GP Term Loans and (2) reserve
requirements of the Camden GP Term Loan, in each case if Camden Cogen's fixed
charge coverage ratio is less than 1.2 to 1.0 and (b) in the absence of a
default under the Camden GP Term Loans. Under the terms of Camden Cogen's
partnership agreement, GECC receives 99% and Camden GPLP 1% of Camden Cogen
Distributable Cash up to a capped amount (approximately $0.3 million to $0.4
million per month through May 2007 and varying amounts thereafter) ("Camden
Tranche 1"). Camden Tranche 1 distributions are set at a level such that, GECC
will receive its initial equity investment and a 6.8% return thereon through
its share of Camden Tranche 1 distributions and the allocation of all venture
tax benefits.
 
 
                                      70
<PAGE>
 
   
  The balance of the Camden Cogen Distributable Cash following satisfaction of
the Camden Tranche 1 obligations, or "Camden Tranche 2", is distributed 99% to
Camden GPLP and 1% to GECC. Payments on Camden Tranche 1 must be made in full
before any payments on Camden Tranche 2 may be made. Distributions of cash
according to the above mechanism end after 17 years and thereafter Camden
Cogen Distributable Cash is to be distributed 10% to GECC and 90% to Camden
GPLP. Historical annual distributions from Camden Cogen are set out in the
table below.

CAMDEN PLANT DESCRIPTION
 
  The Camden Plant is a 146 MW gas-fired, combined-cycle cogeneration facility
developed by one of the Company's subsidiaries and is owned by Camden Cogen.
The Camden Plant is located on a three acre plot of land at the corner of
Broadway and Chelton Avenue in Camden, New Jersey (the "Camden Site"). Power
generated by the Camden Plant is sold to PSE&G, and steam is sold to Camden
Paperboard, a subsidiary of Caraustar Industries, Inc. Steam produced by the
Camden Plant is used by Camden Paperboard in its waste paperboard recycling
process. FERC has certified the Camden Plant as a QF under PURPA.
 
  The Camden Plant was constructed by Ebasco Constructors, Inc. and achieved
commercial operations in March 1993. The Camden Plant is a base load facility
with a nominated summer capacity of 148.5 MW and a nominated winter capacity
of 159.5 MW. The Camden Plant's overall availability and capacity factors have
each been in excess of 92% for each full operating year since it entered
service. The Camden Plant's average availability and capacity factors for the
period from the commercial operations date to December 1997 were 95% and 94%,
respectively. For 1997, the plant's availability and capacity factors were 96%
and 96%, respectively.
 
  The Camden Plant comprises one GE Frame 7EA gas turbine generator and one GE
extractional condensing steam turbine generator. Natural gas is burned
directly in a combustion turbine generator to produce electricity and high
temperature exhaust gases. These exhaust gases are channeled to a Deltak HRSG
to produce high pressure steam for a steam turbine driven electric generator,
providing additional electricity as well as quality process steam for sale to
Camden Paperboard. The steam turbine exhausts into a water cooled surface
condenser to return condensate to the Camden Plant's water cycle. All raw
makeup water is purchased from the City of Camden and treated for use by the
plant's state-of-the-art demineralizer system.
 
  The 13.8 KV electrical power produced by the generators is stepped up to 230
KV and delivered to a gas insulated breaker and outdoor switchgear for
distribution and transmission into the electric grid. An underground
dielectric fluid-cooled cable provides the outgoing power connection to PSE&G.
This cable interconnects with the PSE&G Gloucester Sub-station in Gloucester,
New Jersey, over an interconnection distance of approximately four miles.
 
  The Camden Plant has been designed to meet the stringent environmental
standards of the State of New Jersey. The plant uses BACT to reduce gas
turbine emissions to the level required and permitted by federal and
 
                                      71
<PAGE>
 
state regulators. The Camden Plant incorporates an SCR system to reduce CO and
NOx emissions. NOx and CO emissions levels are further controlled through
steam injection into the turbine combustion chamber and by the design of the
combustion turbine.
 
  The plant design has been optimized based on thermal cycle power output of
140 MW net and average export steam generation to Camden Paperboard of 35,000
lbs/hour.
 
CAMDEN POWER PURCHASE AGREEMENT
 
  The electrical capacity of the Camden Plant is sold to PSE&G pursuant to a
Purchase and Interconnection Agreement (the "Camden PPA"). This agreement
provides for the sale of energy and capacity from the Camden Plant to PSE&G
and for installation of the interconnection with PSE&G that was designed,
constructed and installed by PSE&G. Certain provisions of the Camden PPA are
summarized below.
 
  Term: Base term of 20 years from the date of commercial operation, March
1993, with an option for two five-year renewal periods subject to mutual
agreement of the parties.
 
  Regulatory Approval: Requires approval of the NJBPU, which must find the
contract reasonable and prudent throughout its term, and which must allow
PSE&G full and timely recovery of contract costs through the utility's energy
clause. NJBPU authorization occurred June 1989.
   
  Base Term Pricing--Capacity: PSE&G is required to pay a monthly seasonal
capacity payment for power delivered to PSE&G's receipt point. The payment is
$8.57/KW/month, from January 1, 1988, escalated at 5% per annum; the rate as
of June 30, 1998 was $13.96/KW/month. Payments during certain periods will not
exceed established capacity levels as follows: During the summer peak months
of June through September, the Camden Plant has a nominated capacity of 148.5
MW, and the plant has a nominated capacity of 159.5 MW during the winter peak
months of December through February. The Camden Plant has the right to adjust
these seasonal capacity levels 10% of the original capacity every three years
with a cumulative maximum of 10%. Adjustments to date have resulted in the
cumulative maximum being achieved.     
 
  Base Term Pricing--Energy Fixed: PSE&G will pay an energy charge which has
three components. The fixed energy component is 2.0c/KWh for power delivered
to PSE&G's receipt point, and remains unchanged for 20 years.
   
  Base Term Pricing--Energy Fuel: The fuel energy component, as of January
1988, was 1.73c/KWh for power delivered to PSE&G's receipt point and is
escalated monthly based upon PSE&G's average cost of gas ("ACOG"). The ACOG
equals PSE&G's average gas commodity cost plus a transportation component
equal to PSE&G's interstate pipeline usage charges and one-half of PSE&G's
interstate pipeline reservation charges. The fuel energy component was
1.881c/KWh as of June 30, 1998.     
   
  Base Term Pricing--Energy Inflation: The inflation component, in January
1988, was 0.93c/KWh for power delivered to PSE&G's receipt point and escalates
based on a GDP index. This component tracks closely with a portion of the
pipeline charges and with the Camden Plant's variable O&M costs, which tend to
increase with inflation. The inflation component was 1.241c/KWh as of June 30,
1998.     
 
  Security: There is a tracking account which relates payments PSE&G has made
to Camden Cogen under the Camden PPA to estimated future PJM capacity and
energy rates. These estimates are fixed and set out in the Camden PPA. The
tracking account will reach a maximum of $54 million during 1998 and decline
to zero by year 2001. If a breach by PSE&G were to result in a termination of
the Camden PPA, Camden Cogen would be required to pay to PSE&G the amount, if
any, by which the balance in the tracking account exceeds the liquidated
damages due Camden Cogen as a result of such breach. PSE&G has been granted a
second lien on the Camden Plant to secure its rights with respect to the
security provisions of the Camden PPA.
 
 
                                      72
<PAGE>
 
  Operation--Curtailment: PSE&G is obligated to accept all of the Camden
Plant's net electrical output unless: (i) the Camden Plant fails to comply
with safety requirements, (ii) such acceptance would jeopardize the integrity
or transmission facilities of the PSE&G or PJM systems, (iii) during system
emergencies or planned maintenance of the transmission or interconnection
facilities, or (iv) during light load periods, if due to operational
circumstances, PSE&G would incur costs greater than those that it would have
incurred if it had not made such purchases. As of the date of this Prospectus,
PSE&G has never curtailed deliveries pursuant to these provisions other than
minimum general system emergencies and other than during "light load" periods
which have occurred every year.
 
  Qualifying Facility Status: The Camden Plant must meet FERC's operating and
efficiency standards to maintain its QF status under PURPA. If sections 201
and 210 of PURPA are no longer in effect or the Camden Plant ceases to qualify
as a QF for reasons not within its control, including, a reduction or
cessation in thermal energy use, the Camden PPA will nevertheless continue in
effect provided (i) the NJBPU does not bar PSE&G from passing the rates
through to its customers, (ii) federal, state or local laws are not violated,
and (iii) Camden Cogen or its owners are not subject to unreasonably
burdensome regulation under PUHCA. See "Government Regulation--Federal Energy
Regulation". If one of the above events does occur, Camden Cogen and PSE&G
must negotiate in good faith for an arrangement with substantially similar
economic benefits to each party as are provided to each party under the Camden
PPA. In addition, if one of the above PURPA events occurs, and the NJBPU
denies rate pass-through of PSE&G's obligations under the PSE&G PPA, Camden
Cogen and PSE&G must negotiate in good faith to provide a rate with
substantially similar economic benefits to each party, and which the NJBPU
will permit PSE&G to recover from its ratepayers. If a final non-appealable
order is issued that the Camden Plant is not a QF, then either party may
terminate the Camden PPA, unless the Camden Plant is attempting to restore its
QF status.
 
  Breach of Contract: Among other events, the failure by Camden Cogen to
perform its obligations under the Camden PPA constitutes a breach unless,
within 30 days after notice from PSE&G, Camden Cogen cures the breach or
commences and diligently pursues a cure. For any reason other than force
majeure or curtailment, failure to deliver electric power for 240 out of 365
days constitutes a breach. Such occurrences will be deemed events of default
which, if not remedied in 30 days, may be submitted to a regulatory body with
appropriate jurisdiction or arbitration for resolution.
 
  Insurance: Camden Cogen is required to maintain customary insurance
coverages.
 
  Assignment: The Camden PPA may not be assigned or transferred by either
party without prior written consent except that Camden Cogen may assign to an
affiliate or a lender.
 
  Force Majeure: Either party to the Camden PPA may suspend performance
(except for any obligation to make payments) thereunder due to the occurrence
of force majeure so long as the non-performing party provides prompt notice to
the other party of the force majeure event and expeditiously takes action to
remedy the event excusing performance.
 
CAMDEN STEAM SALES AGREEMENT
 
  Camden Cogen sells steam pursuant to an agreement, dated December 18, 1989,
with Camden Paperboard. Certain provisions of this agreement are summarized
below. Camden Paperboard operates a low-tech industrial plant designed to
recycle waste paperboard for use in folding boxboard and gypsum wallboard
facing paper. Camden Paperboard has been in business since 1911 and is a
wholly-owned subsidiary of Caraustar Industries, Inc.
 
  Term: The agreement provides for a base period of 20 years with an option
for two five-year renewal periods subject to mutual agreement of both parties.
 
  Purchase and Delivery: Camden Cogen will sell and deliver steam up to a
maximum quantity of 60,000 lbs/hour. Camden Paperboard has agreed to accept
and utilize a minimum quantity of steam sufficient to preserve
 
                                      73
<PAGE>
 
the Camden Plant's QF status under PURPA. Camden Paperboard's obligation is
deemed satisfied if it purchases an amount averaging 23,000 lbs/hour from
Camden Cogen. Camden Paperboard is required to return steam condensate in
specified quantities and qualities.
 
  Pricing: Steam is priced in two increments. Camden Paperboard will receive
the first 35,000 lbs/hour at no cost and thereafter pay one-half the avoided
boiler fuel cost per 1,000 lbs/hour in excess of such amount on a monthly
basis.
 
  Suspension of Obligation: Camden Paperboard's obligation to take the minimum
steam required to maintain QF status shall be excused for a maximum of twelve
months in the aggregate due to any of the following: (i) an event of force
majeure; (ii) a major plant overhaul; (iii) retooling or equipment failure; or
(iv) reduced plant capacity at Camden Paperboard's facility due to economic
conditions. After such period, Camden Paperboard's obligation to take steam
will be unaffected by such events or conditions.
 
  Assignment: The Camden Steam Sales Agreement may not be assigned or
transferred by either party without prior written consent of the other party
except that the parties may assign it to an affiliate or a lender.
 
CAMDEN FUEL SUPPLY AGREEMENTS
 
  Camden Cogen entered into a Gas Service Agreement with PSE&G. Under the
terms of the Camden PPA with PSE&G, Camden Cogen is paid a fuel component for
energy which escalates with PSE&G's average cost of gas ("ACOG"). This gives
Camden Cogen an incentive to devise and implement a fuel procurement strategy
that tracks PSE&G's ACOG. For the past eight years and currently, PSE&G's ACOG
has been based primarily on spot market gas prices. Camden Cogen currently has
short-term gas supply agreements with three producers with prices indexed to
spot market prices: Anadarko Energy Services Company, Columbia Energy Services
Corp. and Texaco Natural Gas Inc. Certain provisions of the Gas Service
Agreement with PSE&G are summarized below.
 
  Term: The agreement provides for a base term of 20 years with two 5-year
extensions subject to mutual agreement.
 
  Quantities: PSE&G is to provide the Camden Plant with firm gas
transportation (to burner tip) for up to 30,000 MMBtu/day (the "Camden Resale
Service") and to provide interruptible gas transportation service to Camden
during peak period curtailments if interstate pipeline capacity is available.
 
  Obligations: PSE&G will provide firm transportation for 30,000 MMBtu/day
(plus shrinkage) on a continuous, year round basis subject to a maximum number
of days of interruption per year on any day if the U.S. Weather Bureau has
forecasted certain average temperatures at Newark Airport, Newark, New Jersey.
During such interruptions, the Camden Plant can burn kerosene, Jet-A or L.S.
Diesel, although interruptible gas service may be available via extended
service or through other arrangements that the venture may make for
incremental gas supplies. PSE&G is required to obtain firm gas transportation
for at least 15 years to provide the resale service. PSE&G is responsible for
obtaining any additional regulatory approvals that may be required in the
future.
 
  Camden Cogen is obligated to sell and deliver the contract quantity of gas
to PSE&G at the receipt points and to purchase such gas at the plant upon
delivery by PSE&G during the period April through October. If the venture
cannot supply or accept the contract quantity during this period, it is
obligated to pay PSE&G an agreed upon fee. Camden Cogen has the right to
adjust the contract quantity every three years provided cumulative adjustments
do not exceed certain minimum percentages of the original contract quantity.
Upon curtailment, the Camden Plant may substitute alternative fuels in lieu of
the resale service for a limited number of days per year.
 
  Services: Under the Camden Resale Service arrangement, Camden Cogen
purchases 30,000 MMBtu/day (plus shrinkage) of gas from producers in the Gulf
Coast region of the United States under a portfolio of short to
 
                                      74
<PAGE>
 
intermediate-term, spot price based firm contracts. Gas purchased by Camden
Cogen is sold to PSE&G at a price equal to Camden Cogen's cost and is then
delivered by PSE&G to the Camden Plant and resold to Camden Cogen. FERC Order
636, issued April 1992, prohibits new contracts for such resale transportation
services. This contract is allowed under the grandfather provision of Order
636, but it cannot be extended or renewed.
 
  Pricing: PSE&G purchases gas from Camden Cogen, transports the gas to the
Camden Plant site and resells it to Camden Cogen for the same price plus
certain agreed additional components.
 
  Force Majeure: The Gas Service Agreement between Camden Cogen and PSE&G may
be terminated by the suppliers for lack of performance by Camden Cogen due to
occurrence of force majeure if the inability to perform extends for a certain
specified period of time. Camden Cogen may terminate the Gas Service Agreement
if the supplier experiences a force majeure event for a certain specified
period of time.
 
CAMDEN OPERATION AND MAINTENANCE AGREEMENT
 
  Camden Cogen has entered into an operation and maintenance agreement, dated
effective as of June 6, 1997 (the "Camden O&M Agreement"), with GE. The
initial term of the Camden O&M Agreement is 12 project years. Camden Cogen has
a right to terminate the Camden O&M Agreement by the payment of specified
amounts at the end of each of the fourth, seventh and tenth project years and
a right to extend such agreement for two years after the initial term. The
Camden O&M Agreement is a "cost reimbursable" contract with a monthly
operator's fee and with performance bonuses payable to GE and liquidated
damages assessed against GE based on a series of performance criteria
negotiated with GE and set forth in the Camden O&M Agreement. In 1997, Camden
Cogen paid performance bonuses of $0.1 million to GE, but no operator's fees
were required to be paid in the first partial year of the Camden O&M Agreement
under the terms thereof. Pursuant to the Camden O&M Agreement, the Company
expects operator fees will be paid in future years. Under the Camden O&M
Agreement, Camden Cogen is obligated to buy all parts and services needed at
the Camden Plant from GE at certain discount prices, and GE is obligated to
furnish such parts and services to the plant; provided if GE is unable to
provide such parts or services in a timely or cost effective manner, Camden
Cogen may obtain such parts and services from alternative sources.
 
CAMDEN INSURANCE ARRANGEMENTS
 
  Camden Cogen carries insurance consisting of:
 
 .  ""All Risk" property insurance for direct damage from non-excluded periods
   including but not limited to fire and extended coverage, vandalism, theft,
   collapse, flood, and earthquake. Such coverage is required to be written on
   a replacement cost basis.
 
 .  Comprehensive boiler and machinery insurance for sudden or accidental
   breakdown of mechanical or electrical equipment.
 
 .  ""Single Interest Excess of Loss Policy" insurance is maintained above the
   coverage of the property and boiler machinery policies.
 
 .  Business interruption insurance covering loss of net profits and continuing
   expenses resulting from physical loss or damage at the Camden Plant subject
   to a 30-day deductible.
 
 .  General Liability insurance, employer's liability insurance and excess
   liability insurance.
 
 .  Workers' compensation and employer's liability insurance.
 
CAMDEN ENVIRONMENTAL
 
  All waste water, consisting primarily of cooling tower blowdown, storm
water, boiler blowdown, demineralizer rinse water and sanitary waste, is
processed, and temperature and pH are monitored and controlled prior to
discharge to the Camden County Municipal Utility Authority. Air emissions from
the facility are controlled and reduced through steam injection into the gas
turbine combuster, SCR and turbine design with all
 
                                      75
<PAGE>
 
emissions well below permitted limits. The Company has solid waste disposal
arrangements with contractors it believes to be legally and financially
responsible.
 
CAMDEN SITE ARRANGEMENTS
 
  Camden Cogen owns the Camden Site. Camden Cogen acquired the Camden Site,
which consisted of two adjacent parcels, in January 1992 prior to the
commencement of construction of the Camden Plant.
 
SELKIRK
   
  Selkirk LP is a limited partner in Selkirk Venture, which owns a natural-gas
fired cogeneration facility (the "Selkirk Plant") in Bethlehem, New York. The
Company is not the operator of the Selkirk Plant and its investment in Selkirk
Venture is not material to the business, financial condition, results of
operations or cash flow of the Company taken as a whole. The Company does not
anticipate receiving any material amount of distributions from Selkirk Venture
for the foreseeable future.     
   
  The following chart sets forth, in a simplified manner, the ownership
structure of Selkirk Venture prior to the consummation of the Formation
Transactions.     
  
                             [CHART APPEARS HERE]

- --------
   
(1) The McNair Interests will retain their ownership interest in Cogen
    Technologies Selkirk GP, Inc. following the consummation of the Formation
    Transactions.     
 
  Selkirk Venture has long-term contracts to sell electric capacity and energy
produced by the Selkirk Plant to Niagara Mohawk and Con Ed and steam produced
by such Plant is sold to GE Plastics, a division of GE. Selkirk Venture filed
with the Commission an Annual Report on Form 10-K (the "Selkirk 10-K") for the
year ended December 31, 1997, in which it discusses the circumstances of
Niagara Mohawk's current financial restructuring efforts, including the
possibility of Niagara Mohawk's filing for reorganization under Chapter 11 of
Title 11 of the United States Code, which efforts will likely include a
substantial restructuring of Selkirk Venture's long-term power purchase
agreement with Niagara Mohawk. In the Selkirk 10-K, Selkirk Venture refers to
a Report on Form 8-K filed with the Commission by Niagara Mohawk on July 10,
1997, in which Niagara Mohawk stated that it had entered into the NMMRA
pursuant to which it and 29 independent power producers, including Selkirk
Venture, had agreed to terminate, restate or amend their power purchase
agreements with Niagara Mohawk. The Selkirk 10-K also states that in early
1998 the New York Public Service Commission ("NYPSC") approved Niagara
Mohawk's restructuring proposal, referred to as its "Power Choice" proposal or
settlement, which incorporates the terms of the NMMRA. Under the NMMRA,
Selkirk Venture's power purchase agreement would be substantially amended and
restructured as to price and delivery provisions, but details are still
subject to extensive negotiation and the NMMRA is subject to a number of other
conditions. In
 
                                      76
<PAGE>
 
   
its 10-K filing, Selkirk noted that approximately 19.3% of its revenues in
1997 were attributable to electric sales to Niagara Mohawk. Selkirk Venture
stated in its Report on Form 10-Q for the period ended June 30, 1998, as filed
with the Commission, that if Selkirk Venture and Niagara Mohawk proceed to
complete the transaction provided under the NMMRA, which completion remains
subject to a number of significant contingencies, management of Selkirk
Venture believes that, based on the facts and circumstances currently known,
and certain assumptions that management believes to be reasonable, an amended
agreement is not expected to have a material adverse effect on Selkirk
Venture's future operating results and cash flow from operations.     
 
  Also in the Selkirk 10-K, Selkirk Venture noted that 72.5% of its total
project revenues for 1997 were attributable to electric sales to Con Ed under
its long-term power purchase agreement with Con Ed. Selkirk Venture stated
that it was engaged in a dispute with Con Ed as to a claim by Con Ed that it
has the right to acquire certain excess natural gas supplies of the Selkirk
Plant, which claim, if adversely determined to Selkirk Venture, could
materially and adversely affect the venture's cash flows from electric output.
 
  In the Selkirk 10-K, Selkirk Venture also noted other proceedings,
regulatory matters and on-going negotiations that could materially affect its
future business. The impact of all of such matters on Selkirk Venture,
including the Niagara Mohawk and Con Ed matters, could be to decrease the
likelihood of, or the amount of, future dividends distributed by Selkirk
Venture to the Company.
 
  According to the Selkirk 10-K, the Selkirk Plant is located on an
approximately 15.7 acre site leased from GE adjacent to GE's plastic
manufacturing plant in Bethlehem, New York, and has a total electric
generating capacity of 345 MW with a maximum average steam output of 400,000
lbs/hr. The Selkirk Plant consists of one unit ("Unit 1") with an electric
generating capacity of approximately 79.9 MW and a second unit ("Unit 2") with
an electric generating capacity of approximately 265 MW. The Selkirk Plant
burns natural gas as its primary fuel. The Plant is a "topping-cycle
cogeneration facility", which means that when the Plant is operated in a
combined-cycle mode like the Company's principal plants, it uses natural gas
or fuel oil to produce electricity, and the reject heat from power production
is then used to provide steam. Unit 1 and Unit 2 have been designed to operate
independently for electrical generation, while being thermally integrated for
steam generation, thereby optimizing efficiencies in the combined performance
of the Plant. The Selkirk Plant has been certified as a QF in accordance with
PURPA and the regulations promulgated thereunder by FERC.
 
  The principal and managing general partner of Selkirk Venture is an indirect
wholly-owned subsidiary of a corporation jointly owned, according to the
Selkirk 10-K, by affiliates of PG&E Enterprises and Bechtel Enterprises, Inc.,
which is generally responsible for managing and controlling the business and
affairs of the venture.
 
  The indebtedness of Selkirk Venture (the terms of which contain substantial
restrictions on Selkirk Venture's making cash distributions to its general and
limited partners pursuant to a segregated fund mechanism which provides a
hierarchy of funds, with partnership distribution funds being the lowest into
which cash receipts from the project flow) is not guaranteed by, or otherwise
the obligation of, the Company or any of its subsidiaries except that the
Company's subsidiary which is the 1% general partner in Selkirk Venture has
joint and several general partner liability for the obligations of such
Venture, as does the principal and managing general partner of such Venture,
and the general partnership interest of such subsidiary in Selkirk Venture, as
well as the capital stock of such subsidiary, is pledged to secure the
principal indebtedness of the Selkirk Venture. The general partners have
contribution rights from each other, in proportion to their ownership
interests, to the extent of their general partnership interests. In addition,
Selkirk Venture has agreed to indemnify the general partners against various
potential liabilities which could be incurred by the general partners, with
satisfaction of such indemnity obligation being limited solely to the assets
of Selkirk Venture. The financial statements of Selkirk Venture contained in
the Selkirk 10-K indicate that Selkirk Venture has had positive net income,
cash flows and working capital in the recent periods ended December 31, 1997,
but Selkirk Venture had a negative net worth for accounting purposes as of
such date. In "Item 7 Management's Discussion and Analysis of Financial
Condition and Results of Operations" in the Selkirk 10-K, Selkirk Venture
indicates that, based on current conditions and circumstances, it will have
sufficient liquidity available from cash flows from operations to fund
existing debt obligations and operating costs.

                             GOVERNMENT REGULATION
 
  The Company is subject to complex and stringent energy, environmental and
other governmental laws and regulations at the federal, state and local levels
in connection with the development, ownership and operation of its energy
generation facilities. Federal laws and regulations govern transactions by
electrical and gas utility companies, the types of fuel which may be utilized
by an electric generating plant, the type of energy which may be produced by
such a plant and the ownership structure of a plant. State utility regulatory
commissions may examine the prudence of the rates and, in some instances,
other terms and conditions under which public utilities purchase electric
power from independent producers and approve the rates for sale of retail
electric power. Under certain circumstances where specific exemptions are
otherwise unavailable, state utility regulatory commissions may have broad
jurisdiction over non-utility electric power plants. Energy producing projects
also are subject to federal, state and local laws and administrative
regulations which govern the emissions and other substances produced,
discharged or disposed of by a plant and the geographical location, zoning,
land use and operation of a plant. Applicable federal environmental laws
typically have both state and local enforcement and implementation provisions.
These environmental laws and regulations generally require that a wide variety
of permits and other approvals be obtained before the commencement of
construction or operation of an energy-producing facility and that the
facility then operate in compliance with such permits and approvals.
 
FEDERAL ENERGY REGULATION
 
  PURPA. The enactment of the PURPA and the adoption of regulations thereunder
by FERC provided incentives for the development of cogeneration facilities
like the Company's plants.
 
  A domestic electricity generating project must be a QF under FERC
regulations in order to take advantage of certain rate and regulatory
incentives provided by PURPA. PURPA exempts owners of QFs from PUHCA, and
exempts QFs from most provisions of the Federal Power Act (the "FPA") and,
except under certain limited circumstances, state laws concerning rate or
financial regulation. These exemptions are important to the Company and its
competitors. The Company believes that each of the electricity generating
plants in which the Company owns an interest currently meets the requirements
under PURPA necessary for QF status. Further, the Company has not received any
notice that any of the required regulatory approvals have been revoked or that
FERC or any power purchaser has initiated any regulatory proceedings to revoke
the QF status of any of the Company's plants.
 
  PURPA provides two primary benefits to QFs. First, QFs generally are
relieved of compliance with extensive federal, state and local regulations
that control the organizational and financial structure of an electric
generating plant and the prices and terms on which electricity may be sold by
the plant. Secondly, FERC's regulations promulgated under PURPA require that
electric utilities purchase needed electricity generated by QFs at a price
based on the purchasing utility's Avoided Cost and that the utility sell back-
up power to the QF on a non-discriminatory basis. The term "Avoided Cost" is
defined as the incremental cost to an electric utility of electric energy or
capacity, or both, which, but for the purchase from QFs, such utility would
generate for itself or purchase from another source. FERC regulations also
permit QFs and utilities to negotiate agreements for utility purchases of
power at rates lower than the utility's Avoided Cost. Due to increasing
competition for utility contracts, the current practice is for most power
sales agreements to be awarded at a rate below Avoided Cost. While public
utilities are not explicitly required by PURPA to enter into long-term power
sales agreements, PURPA helped to create a regulatory environment in which it
was common for long-term agreements to be negotiated.
 
  In order to be a QF, a cogeneration facility must produce not only
electricity, but also useful thermal energy for use in an industrial or
commercial process for heating or cooling applications in certain minimum
proportions to the facility's total energy output and must meet certain energy
efficiency standards. Finally, a QF must not be more than 50% owned by an
electric utility company or by an electric utility holding company, or a
subsidiary of such a utility or holding company or any combination thereof, or
receive more than 50% of the stream of economic benefits from the operation of
the QF.
 
                                      78
<PAGE>
 
  The Company endeavors to operate its ventures, monitor compliance by the
ventures with applicable regulations and choose its customers in a manner
which minimizes the risks of any plant losing its QF status. Certain factors
necessary to maintain QF status are, however, subject to the risk of events
outside the Company's control. For example, loss of a thermal energy customer
or failure of a thermal energy customer to take required amounts of thermal
energy from a cogeneration facility that is a QF could cause the facility to
fail to meet requirements regarding the level of useful thermal energy output.
Upon the occurrence of such an event, the Company would seek to replace the
thermal energy customer or find another use for the thermal energy which meets
PURPA's requirements, but no assurance can be given that this would be
possible.
 
  If one of the plants in which the Company has an interest should lose its
status as a QF, the plant would no longer be entitled to the exemptions from
PUHCA, the FPA and state law afforded to QFs. Loss of such exemption could
trigger certain rights of termination under the power sales agreement or any
applicable steam sales agreement as applicable to such plant, could subject
such plant to rate and financial regulation as a public utility under the FPA
and state law and could result in the Company inadvertently becoming a public
utility holding company by owning more than 10% of the voting securities of,
or controlling, a facility that would no longer be exempt from PUHCA. Such
events could cause all of the Company's remaining plants to lose their
qualifying status because QFs may not be controlled or more than 50% owned by
such public utility holding companies. Loss of QF status may also trigger
defaults under covenants to maintain QF status in the ventures' power purchase
agreements, steam sales agreements and financing agreements, and under the
Indenture, and result in termination, penalties or acceleration of
indebtedness under such agreements such that loss of status may be on a
retroactive or a prospective basis. Further, certain of the Company's power
purchase agreements are structured such that the loss of QF status could
result in a reduction in revenues or elimination of the parties' obligations
to perform unless certain conditions are met under the power purchase
agreements. See "Existing Venture and Plant Description--NJ Venture Power
Purchase Agreement--PSE&G" and "Existing Venture and Plant Description--Camden
Power Purchase Agreement".
 
  If a plant were to lose its QF status, the Company could attempt to avoid
holding company status (and thereby protect the QF status of its other plants)
on a prospective basis by restructuring the venture, by changing its voting
interest in the entity owning the non-qualifying plant to nonvoting or limited
partnership interests and selling the voting interests to an individual or
company which could tolerate the lack of exemption from PUHCA, by otherwise
restructuring ownership of the venture so as not to become a holding company
or qualifying as an EWG. These actions, however, would require approval of the
Commission or a no-action letter from the Commission, and would result in a
loss of control over the non-qualifying plant, could result in a reduced
financial interest therein and might result in a modification of the Company's
operation and maintenance agreement relating to such plant. A reduced
financial interest could result in a gain or loss on the sale of the interest
in such plant. Loss of QF status on a retroactive basis could lead to, among
other things, fines and penalties being levied against the Company and its
subsidiaries and claims by utilities for refund of payments previously made
and the termination of the applicable power purchase agreement or a reduction
of payments thereunder.
 
  Under the Energy Policy Act of 1992, if a plant can be qualified as an EWG,
it will be exempt from PUHCA even if it does not qualify as a QF. Therefore,
another response to the loss or potential loss of QF status would be to apply
to have the plant qualified as an EWG. However, assuming this changed status
would be permissible under the terms of the applicable power sales agreement,
rate approval from FERC and approval of the utility would be required. In
addition, the plant would be required to cease selling electricity to any
retail customers (such as the thermal energy customer) and could become
subject to state regulation of sales of thermal energy. See "--Public Utility
Holding Company Regulation."
 
  Public Utility Holding Company Regulation. Under PUHCA, any corporation,
partnership or other legal entity which owns or controls 10% or more of the
outstanding voting securities of a "public utility company" or a company which
is a "holding company" for a public utility company is subject to registration
with the Commission and regulation under PUHCA, unless eligible for an
exemption from regulation under PUHCA. A holding company of a public utility
company that is subject to registration is required by PUHCA to limit its
 
                                      79
<PAGE>
 
utility operations to a single integrated utility system and to divest any
other operations not functionally related to the operation of that utility
system. Approval by the Commission is required for nearly all important
financial and business dealings of a registered holding company. Most QFs are
not public utility companies under PUHCA.
 
  The Energy Policy Act of 1992, among other things, amends PUHCA to allow
EWGs, under certain circumstances, to own and operate non-QFs without
subjecting those producers to registration or regulation under PUHCA. The
expected effect of such amendments would be to enhance the development of non-
QFs which do not have to meet the fuel, production and ownership requirements
of PURPA. The Company believes that the amendments could benefit the Company
by expanding its ability to own and operate facilities that do not qualify for
QF status, but may also result in increased competition by allowing utilities
and others to develop such facilities which are not subject to the constraints
of PUHCA.
 
  Federal Natural Gas Transportation Regulation. The Company has an ownership
interest in and operates three natural gas-fired cogeneration plants. The cost
of natural gas is ordinarily the largest expense (other than debt costs) of a
venture and is critical to the venture's economics. The risks associated with
using natural gas can include the need to arrange transportation of the gas
from great distances, including obtaining removal, export and import authority
if the gas is transported from Canada; the possibility of interruption of the
gas supply or transportation (depending on the quality of the gas reserves
purchased or dedicated to the plant, the financial and operating strength of
the gas supplier and whether firm or non-firm transportation is purchased);
and obligations to take a minimum quantity of gas or pay for it (i.e., take-
or-pay obligations).
 
  Pursuant to the Natural Gas Act, FERC has jurisdiction over the
transportation and storage of natural gas in interstate commerce. With respect
to most transactions that do not involve the construction of pipeline
facilities, regulatory authorization can be obtained on a self-implementing
basis. However, pipeline rates for such services are subject to continuing
FERC oversight.
 
  Proposed Deregulation. The United States Congress is considering proposed
legislation which would repeal PURPA entirely or at least repeal the
obligation of utilities to purchase energy from QFs at Avoided Costs, subject
to any provisions grandfathering existing QF contracts (if such legislation is
passed) and require utilities to conduct competitive bidding for new electric
generation (if the purchase obligation is eliminated) that may be part of any
such legislation. The Company believes that if any such legislation were to be
passed, it most likely would apply only to new plants. As a result, although
such legislation may adversely affect the Company's ability to develop new
plants, the Company believes that it would not affect the existing plants in
which the Company has interests.
 
  Various bills also have proposed the repeal of PUHCA which would eliminate
some of the adverse consequences flowing from a loss of QF status, but also
would likely result in increased competition in the power generation business
and an acceleration of electric industry restructuring. The effect of any such
repeal cannot be predicted, although any such repeal could have a material
adverse effect on the Company.
 
  FERC and many state utility commissions are currently studying a number of
proposals to restructure the electric utility industry in the United States.
Such restructuring could permit utility customers to choose their utility
generator supplier in a competitive electric energy market. FERC issued a
final rule in April 1996 which requires utilities to offer eligible wholesale
transmission customers non-discriminatory open access on utility transmission
lines on a comparable basis to the utilities' own use of the lines. The final
rule has been the subject of rehearing and now is undergoing judicial review.
Many utilities have already filed "open access" tariffs. Utilities contend
that they should recover from departing customers their fixed costs that will
be "stranded" by the ability of their wholesale customers (and perhaps
eventually, their retail customers) to choose new electric power suppliers.
The FERC final rule endorses the recovery of legitimate and verifiable
"stranded costs". These may include the costs utilities are required to pay
under many QF contracts which some utilities view as excessive when compared
with current market prices. Many utilities are therefore seeking ways to lower
these QF contract prices or rescind the contracts altogether out of concern
that their shareholders will be required to
 
                                      80
<PAGE>
 
bear all or part of such "stranded costs". Some utilities have engaged in
litigation against QFs to achieve these ends. In addition, future electric
rates may be deregulated in a restructured United States electric utility
industry and increased competition may result in lower rates and less profit
for sellers of electricity in the United States. Falling electricity prices
and uncertainty as to the future structure of the industry may inhibit United
States utilities from entering into long-term power purchase contracts. The
effect of any such restructuring cannot be predicted, although any such
restructuring could have a material adverse effect on the Company.
 
  The Clinton administration recently announced a proposal to deregulate the
United States electricity markets by the year 2003 under a plan that would
allow consumers to choose which electric company would supply power to their
residences and businesses. Under the proposal, states would not be required to
open their markets to competition, but could retain the current regulatory
scheme if they were to decide that their consumers would benefit from a
regulated monopoly system. In the event that a particular state were to elect
to maintain the status quo, it would be required to hold public hearings to
explain why competition in the electricity market in that state would not be
in the interests of its residents. A number of states already have begun the
process of opening their electricity markets to competition. The
administration's proposal would allow electric utilities to recover reasonable
"stranded costs", funds invested in nuclear and other high-cost power plants
that no longer may be economically viable to operate in a competitive market.
Individual states would determine the amounts of the stranded costs that
utilities would be permitted to recover. The plan also attempts to address
environmental concerns by requiring that 5.5% of the electricity sold in the
United States be generated from renewable energy sources such as the wind or
sun. In addition, the proposal would permit power plants to trade pollution
credits for nitrogen oxides, which combine with other air pollutants to form
ground-level ozone. There can be no assurance that such proposed legislation
will be enacted or, if enacted, as to the effect that it may have on the power
generation industry or the Company's business.
 
STATE ENERGY REGULATION
 
  State public utility commissions ("PUCs") have historically had broad
authority to regulate both the rates charged by, and the financial activities
of, electric utilities and to promulgate regulations for implementation of
PURPA. Since a power sales contract becomes a part of a utility's cost
structure (generally reflected in its retail rates), the utility's costs
associated with power sales contracts with independent electricity producers
are potentially under the regulatory purview of PUCs. If a PUC has approved
the process by which a utility secures its power supply, a PUC is generally
inclined to "pass through" the expense associated with an independent power
contract to the utility's retail customers. However, a regulatory commission
under certain circumstances may disallow the full pass through to a utility
for the cost to purchase power from a QF or other source. In addition, retail
sales of electricity or thermal energy by an independent power producer may be
subject to PUC regulation depending on state law. Independent power producers
which are not QFs under PURPA, or EWGs pursuant to the Energy Policy Act of
1992, are considered to be public utilities in many states and are subject to
broad regulation by a PUC, ranging from the requirement of a certificate of
public convenience and necessity to regulation of organizational, accounting,
financial and other corporate matters. States may assert jurisdiction over the
siting and construction of electric generating facilities including QFs and,
with the exception of QFs, over the issuance of securities and the sale or
other transfer of assets by these facilities.
 
  New Jersey. Industry restructuring efforts are also underway in New Jersey.
On April 30, 1997, NJBPU issued an order adopting its Final Report in the
Energy Master Planning Process entitled, "Restructuring the Electric Power
Industry in New Jersey: Findings and Recommendations". The principal announced
goal of NJBPU in its Final Report is to open the electric generation market to
increased competition and thereby reduce generation and production costs. On
July 15, 1997, each of New Jersey's four electric utility companies filed: (1)
a Restructuring Plan, (2) an Unbundled Rate Filing, and (3) a Stranded Costs
Filing with NJBPU pursuant to NJBPU's Final Report. On July 1, 1998, NJBPU
released a revised version of its prior draft of proposed legislation to
restructure New Jersey's electric power industry (see NJ Stranded Costs),
which revisions included provisions requiring that each electric utility
"shall fully implement retail choice in 100% of its franchise area within the
State of New Jersey by July 1, 1999".
 
 
                                      81
<PAGE>
 
  NJ Stranded Costs. The stranded costs filing of each utility will determine
the specific initial level of non-mitigatable stranded costs to be recovered
by each utility. Each of these stranded costs filings has been transmitted to
the Office of Administrative Law for evidentiary hearings. The JCP&L hearing
commenced on December 2, 1997; the Initial Decision from the Administrative
Law Judge was due on May 15, 1998, with a Final Decision by NJBPU due
thereafter.
 
  NJBPU concluded in its Final Report that electric utilities "should be given
an opportunity to recover from customers the costs associated with past
financial commitments made by the utility for the purpose of procuring
generating supplies to serve the retail electric customers in their service
territory". NJBPU also concluded, however, "there neither can nor should be a
guarantee provided for 100% recovery of stranded costs". These pronouncements
remain subject to current and future regulatory proceedings and actions by the
New Jersey Legislature. Additionally, federal legislation has been proposed
that may alter a state's ability to regulate the emerging competitive market
and the recovery of stranded costs. See "Risk Factors--Dependence on Third
Parties".
 
  On March 2, 1998, NJBPU released draft legislation for the restructuring of
the electric power industry in New Jersey, which included provisions for the
determination and recovery of stranded costs of electric utilities. Stranded
costs are defined by NJBPU in that draft legislation "as the amount by which
the net cost of an electric public utility's electric generating assets or
electric power purchase commitments, as determined by NJBPU pursuant to this
Act, exceeds the market value of those assets or contractual commitments in a
competitive supply market place". NJBPU seeks to address the stranded costs
that may be created as a result of its decision "to open the power generation
market up to competition". NJBPU has determined to "limit the eligibility for
stranded cost surcharge recovery to costs related directly to utility power
supply" including, "utility generation plant, long and short-term power
purchase contracts with other utilities and long-term power purchase contracts
with non-utility generators".
 
  NJ Above Market Power Purchase Contracts. The JCP&L PPA received initial
regulatory approval on December 16, 1985 and final approval of the contract
amendment on December 8, 1986. The PSE&G PPA received regulatory approval on
July 5, 1989. The Camden PPA (with PSE&G) received initial approval on June
29, 1989 and final approval of contract amendments on February 27, 1991. The
approval orders found all contracts reasonable, fairly negotiated and prudent
through the term of the contract and permit recovery of all costs through the
companies' fuel clauses. Both PSE&G contracts contain a section entitled
"Repeal of PURPA" explaining the process for resolution of possible
disallowance of costs by NJBPU. NJBPU stated in its Final Report that
utilities must and should "take all available measures to mitigate stranded
costs caused by the introduction of retail competition", including the "buy-
out or renegotiation of existing purchased power contracts with non-utility
generators". NJBPU has acknowledged that it appears to lack jurisdiction to
order modification of non-utility generators' contracts, and has determined
that the "non-mitigatable costs associated with all such contracts which have
previously been reviewed and approved by NJBPU, notwithstanding the specific
date, must be eligible for stranded cost recovery."
 
  NJBPU based its determination that it lacks jurisdiction to order
modification of non-utility generators' contracts on the decision of the Third
Circuit Court of Appeals in Freehold Cogeneration Associates, L.P. v. Board of
Regulatory Commissioners of New Jersey, 44 F.3d. 1178 (3rd Cir. 1995), cert.
den., 516 U.S. 815, which held that:
 
  Once the [NJBPU] approved the power purchase agreement between Freehold and
  JCP&L, on the grounds that the rates were consistent with avoided cost, any
  action or order by the [NJBPU] to reconsider its approval or to deny the
  passage of those rates to JCP&L consumers under purported state authority
  was preempted by federal law. (Id., Freehold 44 F.3d at 1194).
 
  NJBPU has interpreted the Freehold decision to mean that without legislative
action at the federal or state level, a state regulator has minimal ability to
subsequently adjust the pricing in such non-utility generators' contracts once
approved.
 
                                      82
<PAGE>
 
  Notwithstanding NJBPU's acknowledgment that it appears to lack jurisdiction
to order modification of non-utility generators' contracts under current law,
it has "strongly encouraged all stakeholders to renew their efforts to explore
all reasonable means to mitigate IPP contracts". NJBPU further stated that the
appropriate regulatory and legislative bodies may "wish to review this issue
to provide an added impetus for parties to these contracts to seriously
consider mitigation." JCP&L has reported to NJBPU that it intends to pursue
efforts to mitigate its above-market costs for non-utility generator purchase
power agreements on a voluntary basis.
 
  New York. The NYPSC is conducting a generic "competitive opportunities"
proceeding through which it is examining how to introduce greater competition
into the electric utility industry in New York. This process began in March
1993 with a Phase I proceeding, and continued into 1994 with the start of a
Phase II proceeding. In June 1995, NYPSC adopted a set of principles to guide
its Phase II investigation. In December 1995, an administrative law judge
recommended that NYPSC implement wholesale and retail competition. On May 20,
1996, NYPSC issued a final order in the Phase II "competitive opportunities"
case in which it endorsed a fundamental restructuring of the electric
industry. NYPSC's goals as stated in that order are lower prices for customers
from competition, increased choice of suppliers and services for customers,
information dissemination to allow educated customer decisions, maintenance of
the reliability of the electric system, continuation of social/conservation
programs, mitigation of market power, and continuation of the obligation to
serve customers. To commence the transition process, NYPSC required the larger
investor-owned utilities to submit, by October 1, 1996, a transition plan that
addresses market structure issues, corporate structure issues, operational
constraints, the schedule for customer choice, unbundled prices, and a rate
plan for the duration of the transition.
 
  Con Ed made a filing in compliance with this order on October 1, 1996. In
September 1997, the NYPSC approved a settlement agreement between Con Ed, the
NYPSC staff and certain other parties. The settlement agreement includes,
among other things the recovery of at least 90% of stranded costs relating to
non-utility generator ("NUG") contracts (including Linden). Any disallowance
below 100% recovery of these stranded costs will be reduced by, among other
factors, NUG contract mitigation achieved by Con Ed.
 
  New York--Linden Venture Contract. Linden Venture received initial
regulatory approval on September 12, 1989, and final approval of contract
amendments on May 9, 1991, pursuant to a Con Ed petition for approval,
supported by an affirmative recommendation from the NYPSC staff. The approval
was based on estimates that the venture would be less costly than existing
ventures of Con Ed's long-run avoided cost. NYPSC granted "recovery of all
direct purchase costs incurred pursuant to the Linden PPA through the
utility's fuel adjustment clause". To the extent Linden Venture operates in
conformance with the Linden PPA, Con Ed is entitled to full cost recovery
without any subsequent regulatory requirements. There are ongoing
investigations into certain aspects of NYPSC regulation of non-utility
generators in New York. NYPSC has granted utilities permission to closely
monitor the QF status of plants in the state. There is still pending a request
by the utilities to enable them to curtail "must-run" plants; however, the
Linden Venture contract has a specific exemption from any such request. There
is no litigation pending between Linden Venture and Con Ed.
 
  Other State Regulation. State PUCs also have jurisdiction over the
transportation of natural gas by local distribution companies ("LDCs"). Each
state's regulatory laws are somewhat different; however, all generally require
the LDC to obtain approval from the PUC for the construction of facilities and
transportation services if the LDC's generally applicable tariffs do not cover
the proposed transaction. LDC rates are usually subject to continuing PUC
oversight.
 
ENVIRONMENTAL REGULATIONS
 
  The construction and operation of power projects are subject to extensive
federal, state and local laws and regulations adopted for the protection of
the environment and to regulate land use. The laws and regulations applicable
to the Company primarily involve the discharge of emissions into the water and
air and the use of water, but can also include wetlands preservation,
endangered species, waste disposal and noise regulations. These laws and
regulations in many cases require a lengthy and complex process of obtaining
licenses, permits and approvals from federal, state and local agencies as well
as ongoing reporting and compliance obligations.
 
                                      83
<PAGE>
 
Additional or modified licenses, permits and approvals may be required for any
physical or operational changes to the Company's facilities. As discussed
below, the Company believes it is in material compliance with all such laws
and regulations.
 
  Noncompliance with environmental laws and regulations can result in the
imposition of civil or criminal fines or penalties. In some instances,
environmental laws also may impose cleanup or other remedial obligation in the
event of a release of pollutants or contaminants into the environment. The
following federal and state laws are among the more significant environmental
laws as they apply to the Company. The state laws impose requirements on the
Company that are similar, and in some cases more stringent, than the
requirements in the analogous federal laws.
 
  The Clean Air Act provides for the regulation, largely through state
implementation of federal requirements, of emissions of air pollutants from
certain facilities and operations, including an obligation to obtain
preconstruction and operating permits for sources of air pollution. In New
Jersey, the requirements of the Clean Air Act are implemented through the
State Air Pollution Control Act and implementing regulations. As originally
enacted, the Clean Air Act set guidelines for emission standards for major
pollutants (e.g., sulfur dioxide and oxides of nitrogen) from newly built
sources. In late 1990, significant amendments to the Clean Air Act were
adopted. The 1990 Amendments attempt to reduce emissions from existing
sources, particularly previously exempted older power plants. The Company
believes that all of the Company's operating plants are in compliance in all
material respects with the applicable federal and state performance standards
under the Clean Air Act, the 1990 Amendments and the State Air Pollution
Control Act.
 
  In addition to the above, the 1990 Amendments established the Northeast
Ozone Transport Region ("NEOTR") which required various states, including New
Jersey, to adopt more stringent controls on the pollutants that contribute to
the formation of low-level ozone (i.e., volatile organic compounds and oxides
of nitrogen). Pursuant to a September 27, 1994 Memorandum of Understanding
between the member states of the NEOTR, New Jersey has proposed regulations to
implement a region-wide budget for nitrogen oxide emissions. While the
Company's operating plants will be subject to this new rule (as presently
drafted), and therefore will be subject to additional operating limits, the
Company believes that the new rules will not have a material impact on its
ability to maintain its present level of operations.
 
  The Federal Clean Water Act (the "Clean Water Act") and the New Jersey Water
Pollution Control Act (the "Water Pollution Control Act") establish rules
regulating the discharge of pollutants into surface and ground waters. The
Clean Water Act and the Water Pollution Control Act also establish
requirements for municipally-owned sewage treatment plants, including
pretreatment requirements for industrial users of those plants. Each local
municipal sewerage authority has established regulations governing connections
to and discharges into its sewer system and treatment plants. Pursuant to
these federal, state and local laws and regulations, the Company is required
to obtain permits for the discharge of its wastewater and storm water runoff.
The Company believes that it is in material compliance with applicable
discharge requirements under the Clean Water Act, the Water Pollution Control
Act and applicable local regulations.
 
  The Resource Conservation and Recovery Act ("RCRA") regulates the
generation, treatment, storage, handling, transportation and disposal of solid
and hazardous waste. The Company generates certain non-hazardous and hazardous
wastes that are subject to the requirements of RCRA and parallel state
statutes. The hazardous wastes that the Company generates are subject to more
rigorous and costly disposal requirements than are non-hazardous wastes,
although the cost of disposal is not anticipated to be material. The Company
believes that it is in substantial compliance with the RCRA and the parallel
state regulations.
 
  The Comprehensive Environmental Response, Compensation and Liability Act of
1980, as amended ("CERCLA" or "Superfund"), requires cleanup of sites from
which there has been a release or threatened release of hazardous substances
and authorizes the United States Environmental Protection Agency ("EPA") to
take any necessary response action at Superfund sites, including ordering
potentially responsible parties ("PRPs") that are liable for the release to
take or pay for such actions. PRPs are broadly defined under CERCLA
 
                                      84
<PAGE>
 
to include past and present owners and operators of, as well as generators of
wastes sent to, a site. In addition, the New Jersey Spill Act ("Spill Act")
imposes similar liability under state law for discharges of hazardous
substances (including petroleum products) and, under certain circumstances,
authorizes the collection of treble damages from a responsible party. Similar
to CERCLA, the definition of who is responsible is broadly defined to include
owners and operators of the facility where the discharge occurred, the owners
of the hazardous substance that is discharged, or anyone who has caused or
allowed the discharge to occur. As of the present time, the Company is not
subject to liability for any Superfund or Spill Act matters. However, the
Company generates certain wastes, including hazardous wastes, and sends
certain of its wastes to third-party waste disposal sites. As a result, there
can be no assurance that the Company will not incur liability under CERCLA or
the Spill Act in the future.
 
  The Spill Act also requires facilities that store significant quantities of
petroleum products or other hazardous substances to prepare detailed discharge
prevention containment and countermeasure plans and discharge cleanup and
removal plans. The Company believes that it is in substantial compliance with
these regulations with respect to each of its operating plants.
 
  The New Jersey Toxic Catastrophe Prevention Act ("TCPA") requires owners of
facilities that use an "extraordinarily hazardous substance" to prepare a
comprehensive risk management plan pertaining to its use of such substances.
The Company's Bayonne Facility is subject to these requirements due to its use
of anhydrous ammonia in its air pollution control systems. The Company
believes that it is in material compliance with the TCPA requirements.
 
  Because the Formation Transactions and the Common Stock Offering will
involve a significant change in the ownership structure of the entities that
own the operating plants, the Formation Transactions may trigger the Company's
obligations pursuant to the New Jersey Industrial Site Recovery Act ("ISRA").
ISRA requires the owner or operator of an industrial establishment to notify
the New Jersey Department of Environmental Protection ("NJDEP") of the pending
transaction and to obtain NJDEP approval prior to the closing of any such sale
of ownership interests. In order to obtain NJDEP approval for a proposed
transaction, the owner or operator must conduct a satisfactory investigation
of the environmental conditions of the industrial establishment and, if
necessary, commit to undertake appropriate remedial measures to address any
contamination present at the industrial establishment. Based upon the history
of the construction and operation of the Company's facilities, previous
investigations of site conditions, and the status of ongoing remediation
projects currently being undertaken by current or prior owners of the
properties, the Company believes that it will not incur any material cost as a
result of its compliance with ISRA.
 
  To the extent the Company acquires interests in plants in other states, such
plants will be subject to such states' implementation of federal law and other
state and local environmental laws and regulations.

will expire at the 1999 annual meeting of stockholders, the terms of office of
Messrs. Burguieres and Gillis will expire at the 2000 annual meeting of
stockholders and the terms of office of Messrs. Lawrence and McNair will
expire at the 2001 annual meeting of stockholders.
 
BOARD COMMITTEES
 
   Cogen's Board of Directors has established an Audit Committee and a
Compensation Committee.
 
  The duties of the Audit Committee are to recommend to the Board of Directors
the selection of independent public accountants to audit annually the books
and records of the Company, discuss with the independent auditors and internal
auditors the scope and results of audits and approve and review any nonaudit
services performed by the Company's independent auditing firm.
 
  The duties of the Compensation Committee are to provide a general review of
the Company's compensation and benefit plans to ensure that they meet the
Company's objectives. In addition, the Compensation Committee approves the
Chief Executive Officer's compensation and reviews the Chief Executive
Officer's recommendations on (i) the compensation of all other officers of the
Company, (ii) the grant of awards under the Company's then existing
compensation and benefit plans and (iii) the adoption of major Company
compensation policies and practices. The Compensation Committee also
administers the Company's 1998 Employee Stock Compensation Plan (the "Employee
Plan").
 
BOARD COMPENSATION
 
  Non-employee directors of the Company will be paid a quarterly director's
fee of $6,000 plus $2,000 for each board meeting attended. The Chairman of
each of the Audit and Compensation Committees will be paid an annual fee of
$2,000, and each director who is a member of a committee of the Board of
Directors will receive $1,000 for each committee meeting attended. In
addition, the Chairman of the Executive Committee will receive an annual fee
of $200,000 and an option to purchase 250,000 shares of Common Stock at an
exercise price equal to the Common Stock Offering price per share.
 
  Each of the non-employee directors is entitled to receive options under the
Company's 1998 Non-Employee Director Stock Option Plan (the "Director Plan").
The Director Plan was adopted for the benefit of directors of the Company who,
at the time of their service, were not employees of the Company or its
subsidiaries. The
 
                                      88
<PAGE>
 
   
Director Plan is designed to advance the interests of the Company by providing
such non-employee directors with additional incentive to promote the success
of the Company's business and to enhance the Company's ability to attract,
retain and motivate non-employee directors with compensatory arrangements that
provide for or increase the proprietary interests of such persons in the
Company. The Director Plan was approved and adopted by the Board of Directors
and the Company's stockholders in August 1998 and is administered by the full
Board of Directors. Subject to certain anti-dilution provisions in the
Director Plan, an aggregate of .5455% of the issued and outstanding Common
Stock immediately following the consummation of the Formation Transactions
(300,000 shares assuming a Common Stock Offering price of $15.00 per share)
has been reserved for issuance under the Director Plan upon the exercise of
options granted under such plan. Immediately prior to the consummation of the
Common Stock Offering, options to purchase an aggregate of 50,000 shares of
Common Stock will be outstanding under the Director Plan at an exercise price
equal to the per share Common Stock Offering price. The Board of Directors of
the Company, in its sole discretion, may amend or terminate the Director Plan,
except that no amendment may decrease the exercise price below the fair market
value of the Common Stock at the date of grant.     
 
  Pursuant to the terms of the Director Plan, each person serving as a
director of the Company immediately prior to the consummation of the Common
Stock Offering and who is not an employee of the Company or any of its
subsidiaries was will be granted options to purchase 10,000 shares of Common
Stock (the "Initial Director Options") at an exercise price equal to the
Common Stock Offering price per share. Under the Director Plan, upon election
to the Company's Board of Directors each non-employee director who was not a
director immediately prior to the consummation of the Common Stock Offering
shall be granted options to purchase 10,000 shares of Common Stock (the "New
Director Options"). In addition, the Director Plan provides for the automatic
grant of options to purchase 5,000 shares of Common Stock at an exercise price
equal to the fair market value of the Common Stock on the date of grant to
each person who is a non-employee director of the Company on any December 31
while the Director Plan is in effect (the "Vested Options").
 
  All options granted under the Director Plan will have an exercise price per
share of Common Stock equal to the fair market value of the Common Stock on
the date of grant. Each of the Initial Director Options and the New Director
Options is exercisable only in one-third increments over a three-year period
commencing on the first anniversary of the date of the grant of such options.
The Vested Options are immediately exercisable in full when granted. In the
event of certain corporate transactions, the Board of Directors has discretion
to (i) accelerate the time at which options granted under the Director Plan
may be exercised, (ii) require the mandatory surrender of such options in
exchange for cash or (iii) make certain adjustments to such options. All
options granted under the Director Plan will be nonqualified stock options
that will not qualify as incentive stock options under section 422 of the
Code.
 
  Options granted under the Director Plan have a term equal to the earlier of
(i) three years from the date the non-employee director ceases to be a
director of the Company for any reason other than death, disability or
retirement, and (ii) ten years from the date of grant of such option. In the
event of the death, disability or retirement of the non-employee director,
such non-employee director's options shall continue to vest until such options
expire ten years after the date of grant of such option and, in the event of
death, such non-employee director's options may be exercised by his executors,
administrators or any person or persons to whom his options may be transferred
by will or the laws of descent and distribution, as the case may be. Options
granted under the Director Plan are not transferable by the non-employee
director except upon death of the non-employee director as noted above and for
certain limited transfers within a family or for estate planning purposes.

EMPLOYMENT AGREEMENTS
 
  The Company expects to enter into change-in-control agreements with certain

EMPLOYEE PLANS
 
 1998 Employee Stock Compensation Plan
   
  The Employee Plan is designed to advance the interests of the Company and
its stockholders by providing key employees of the Company or any of its
subsidiaries and consultants and advisors to the Company additional incentive
to promote the success of the Company's business and to enhance the Company's
ability to attract, retain and motivate key employees, consultants and
advisors through the use of compensatory arrangements that provide for or
increase the proprietary interests of such persons in the Company. The
Employee Plan was approved and adopted by the Board of Directors and the
Company's stockholders in August 1998 and is administered by the Compensation
Committee. Subject to certain anti-dilution provisions in the Employee Plan,
an aggregate of 11.9546% of the issued and outstanding shares of Common Stock
immediately following the consummation of the Formation Transactions
(6,575,000 shares assuming a Common Stock Offering price of $15.00 per share)
has been reserved for issuance under the Employee Plan upon the exercise of
options granted under the Employee Plan or pursuant to the grant of restricted
stock awards under the Employee Plan. Options granted under the Employee Plan
may be either incentive stock options as defined in section 422 of the Code
("ISOs"), or nonqualified stock options. Immediately prior to the consummation
of the Common Stock Offering, the Company will grant options to purchase an
aggregate of approximately 2,500,000 shares of Common Stock at an exercise
price equal to the per share Common Stock Offering price. No options may be
granted under the Employee Plan after August    , 2008. The Board of Directors
has the power to amend, terminate or suspend the Employee Plan in its sole
discretion except that certain amendments require the approval of the
Company's stockholders to maintain the status of ISOs under the Code.     
   
  Under the Employee Plan, ISOs may be granted to those key employees of the
Company or its subsidiaries as the Compensation Committee may determine from
time to time. Nonqualified stock options and restricted stock awards (ISOs,
nonqualified stock options and restricted stock awards collectively referred
to herein as "Awards") may be granted to those employees, consultants,
advisors and directors who have substantial responsibility for the management
and growth of the Company or its affiliates as the Compensation Committee
shall determine from time to time. Pursuant to the terms of the Employee Plan,
the Compensation Committee may only grant (i) ISOs to purchase an aggregate of
11.5449% of the issued and outstanding shares of Common Stock immediately
following the consummation of the Formation Transactions (6,349,667 shares
assuming a Common Stock Offering price of $15.00 per share) and (ii)
restricted stock awards of an aggregate of .4097% of the issued and
outstanding shares of Common Stock immediately following the consummation of
the Formation Transactions (225,333 shares assuming a Common Stock Offering
price of $15.00 per share) shares of Common Stock and may only grant options
to purchase an aggregate of 2.7272% of the issued and outstanding shares of
Common Stock immediately following the consummation of the Formation
Transactions (1,500,000 shares assuming a Common Stock offering price of
$15.00 per share) shares of Common Stock to any person in a calendar year. All
ISOs under the Employee Plan are nontransferable except by will or under the
laws of descent and distribution. Nonqualified stock options and restricted
stock awards are generally nontransferable except by will or under the laws of
descent and distribution, unless otherwise provided for by the Compensation
Committee in its sole discretion. In the event of certain corporate
transactions, the Compensation Committee has discretion to (i) accelerate the
time at which Awards granted under the Employee Plan may be exercised, (ii)
require the mandatory surrender of such Awards in exchange for cash or (iii)
make certain adjustments to such Awards.     
 
 
                                      90
<PAGE>
 
   
  The Employee Plan provides that the Compensation Committee shall specify
whether options granted under the Employee Plan are ISOs or nonqualified stock
options, provided that notwithstanding such designation, ISOs shall be treated
as nonqualified stock options under certain circumstances as may be required
by law. The exercise price for options granted under the Employee Plan will
generally be equal to the fair market value of the Common Stock on the date of
grant, but the Compensation Committee in its discretion may determine a higher
exercise price. In the case of a 10% stockholder, the exercise price for ISOs
granted under the Employee Plan may not be less than 110% of the fair market
value of the Common Stock on the date of grant. Options granted under the
Employee Plan generally terminate on the earlier of (i) ten years from the
date of grant (five years from the date of grant for ISOs in the case of a 10%
stockholder) and (ii) one day less than three months after the severance of
the employment or affiliation relationship between the option holder and the
Company and all of its subsidiaries for any reason except for death,
retirement or disability. Options may be exercised at the time, in the manner
and subject to the conditions the Compensation Committee specifies in its sole
discretion. Immediately prior to the consummation of the Common Stock
Offering, the Company plans to grant options to purchase an aggregate of
approximately 2,500,000 shares of Common Stock, at an exercise price equal to
the Common Stock Offering price per share, to certain employees, of which
options to purchase an aggregate of 1,341,000 shares of Common Stock will be
granted to the Chief Executive Officer and other executive officers.     
   
  Under the Employee Plan, the Compensation Committee may also issue shares of
restricted stock to eligible persons selected by it. The amount of, and
vesting and transferability restrictions applicable to, restricted stock
awards are determined by the Compensation Committee in its sole discretion.
Immediately prior to the consummation of the Common Stock Offering, the
Company plans to grant an aggregate of 225,333 shares of restricted stock
(valued at the Common Stock Offering price per share) to certain executive
officers.     
 
  The Company also intends to adopt a 401(k) plan.
 
MANAGEMENT SERVICES AGREEMENTS
 
  The Company expects to enter into agreements with various other entities
controlled by Robert C. McNair pursuant to which Cogen would provide services
including certain management, financial and administrative support to such
entities. See "Certain Transactions--Other Transactions". In addition, NJ Inc.
has entered into management services agreements with an entity indirectly
owned and controlled by Robert C. McNair. See "Certain Transactions--Other

                             CERTAIN TRANSACTIONS
 
FORMATION TRANSACTIONS
 
  Cogen was incorporated in May 1998 at the instance of Robert C. McNair to
acquire operating control of, and a substantial equity interest in (or, in the
case of Selkirk Venture, only a passive equity interest in), a group of
affiliated entities (the subsidiaries) beneficially owned approximately 82% by
the McNair Interests and approximately 18% by the Minority Interests. Mr.
McNair and the McNair Interests may constitute "promoters" or "founders" under
Rule 405 of the Securities Act. In connection with its organization, Cogen
issued an aggregate of 1,000 shares of Common Stock to the holders of the
McNair Interests and the holders of the Minority Interests in their respective
82% and 18% ratios in consideration for the proportionate payment of an
aggregate of $1,000 to Cogen. In connection with the Common Stock Offering,
the following transactions will be consummated simultaneously immediately
prior to the consummation of the Common Stock Offering (dollar and share
amounts are estimates based on an assumed Common Stock Offering Price of
$15.00 per share):
     
  First, 49.9% of the general partner interests and 49.9% of the limited
  partner interests of Linden Ltd., a limited partnership which is the
  general partner in the Linden Venture, which owns and operates the Linden
  Plant will be transferred by the McNair Interests and the Minority
  Interests, respectively, to Cogen or a subsidiary thereof in consideration
  for the issuance to the McNair Interests of 23.5 million shares of Common
  Stock and to the Minority Interests of 5.2 million shares of Common Stock.
         
  Second (i) 100% of the stock of Camden, Inc., which is the general partner
  in Camden GPLP, a limited partnership which is the general partner of
  Camden Cogen, another limited partnership which constitutes the venture
  that owns and operates the Camden Plant, and (ii) all the equity interests
  in Camden GPLP represented by the limited partnership interests therein
  owned by the Minority Interests, will be transferred by the McNair
  Interests and the Minority Interests to Cogen or a subsidiary thereof in
  consideration for the payment and issuance to the McNair Interests of an
  aggregate of $820,000 in cash and 8.1 million shares of Common Stock and to
  the Minority Interests of an aggregate of $180,000 in cash and 1.8 million
  shares of Common Stock.     
     
  Third, MESC, a Texas corporation approximately 82% owned by the McNair
  Interests and approximately 18% owned by the Minority Interests, will be
  merged with Cogen Technologies Bayonne, Inc., a wholly owned subsidiary of
  Cogen ("Bayonne Newco"), pursuant to which merger Bayonne Newco will
  survive and the stockholders of MESC will receive 14.4 million shares of
  Common Stock in proportion to their ownership. MESC owns NJ Inc., which is
  the operating and 91.75% managing general partner of NJ Venture, which owns
  the Bayonne Plant.     
     
  Fourth, the McNair Interests and the Minority Interests will transfer
  directly or indirectly their general and limited partnership interests in
  Selkirk LP which holds limited partner interests in Selkirk Cogen Partners,
  L.P., which owns the Selkirk Plant, to Cogen or a subsidiary thereof, in
  consideration for 1.7 million shares of Common Stock. The McNair Interests
  will retain their ownership of Cogen Technologies Selkirk GP, Inc., which
  holds a 1% general partnership interest in Selkirk Venture.     
     
  Fifth, Financial Services, a limited partnership owned by the McNair
  Interests and the Minority Interests, will transfer its 100% ownership in
  CT Global, engaged at present solely in the business of insuring the first
  levels of property and casualty insurance for the Company's principal
  plants (the "Insurance Subsidiary"), to the Company in consideration for
  0.3 million shares of Common Stock.     
     
  Finally and immediately after the transactions described in the five
  preceding paragraphs, the remaining equity interests in Linden Ltd. owned
  by the McNair Interests and the Minority Interests will be redeemed by
  Linden Ltd. in consideration for the proportionate distribution to the
  McNair Interests and the Minority Interests of an account receivable in the
  amount of $140.4 million owed to Linden Ltd. by Financial Services and the
  proportionate payment to the McNair Interests and the Minority Interests of
  $291.0 million in cash. The funds for such redemption will be borrowed by
  Linden Ltd. from Morgan Stanley & Co. Incorporated pursuant to the Bridge
  Loan Agreement.     
 
 
                                      92
<PAGE>
 
   
  After the consummation of all the foregoing transactions (the "Formation
Transactions") and the Common Stock Offering, Cogen will have outstanding
55,000,000 shares of Common Stock, of which 18.5 million shares (33.6%) will
be owned by the McNair Interests, 3.2 million shares (5.8%) will be owned by
the Minority Interests, and 33.3 million shares (60.6%) will be owned by the
public. See "Principal and Selling Stockholders". Further, Cogen will own,
directly or indirectly, all of the equity interests currently held by the
McNair Interests and the Minority Interests in the ventures that operate and
own the Linden, Bayonne and Camden Plants and also the equity interests of the
McNair and Minority Interests held by Selkirk LP in the venture which owns the
Selkirk Plant, as well as 100% of CT Global. The McNair Interests will receive
an aggregate of approximately $239.4 million in cash, 82% of a receivable from
Financial Services, an entity not owned by Cogen, having a face value of
$115.1 million and 45.1 million shares of Common Stock in connection with the
Formation Transactions, although the only consideration to be paid to the
McNair Interests by Cogen is the shares of Common Stock thereof and $820,000
in cash. In addition, in connection with the Formation Transactions, RCM, a
limited partnership indirectly owned and controlled by Robert C. McNair, will
receive an aggregate of $74.0 million in consideration for the termination of
certain existing management services agreements between RCM and Camden GPLP,
Linden Ltd. and Selkirk LP and one of the Minority Interests will receive from
Linden Venture, Camden Cogen and Selkirk LP, an aggregate of $9.7 million in
consideration for the termination of certain gas management agreements between
him and Cogen Technologies Capital Company, L.P.     
   
  Immediately after consummation of the Debt Offering, the Company will
advance as a loan to Linden Ltd., a portion of the Debt Offering proceeds
necessary for Linden Ltd. to repay, in full, the $291.0 million Bridge Loan.
       
  In addition, to facilitate the consummation of the Formation Transactions,
immediately prior to the consummation of the Common Stock Offering, Morgan
Stanley & Co. Incorporated will loan an aggregate of $83.9 million to the
McNair Interests and the Minority Interests, which will be repaid from a
portion of the proceeds of the Common Stock Offering.     
 
  The consummation of the Formation Transactions and, thus, the consummation
of the Common Stock Offering are subject to the various entities that are
parties to the Formation Transactions obtaining all necessary consents of
other partners in, and lenders to, the entities which are to be owned directly
or indirectly by the Company after the consummation of the Formation
Transactions.
 
  For a chart showing, in a simplified manner, the organizational structure of
the Company with respect to its interests in the ventures immediately
following the consummation of the Formation Transactions, see "Prospectus
Summary--Formation".
 
OTHER TRANSACTIONS
   
  NJ Inc. has entered into a management services agreement with RCM, pursuant
to which RCM provides certain management services for NJ Venture. RCM is a
Delaware limited partnership that is indirectly owned and controlled by Robert
C. McNair. The agreement with NJ Inc. was entered into in September 1989,
expires on the date NJ Inc. ceases to be the managing venturer of NJ Venture
(or if earlier terminated pursuant to cause as defined therein) and provides
that NJ Inc. will pay or cause NJ Venture to pay to RCM a management fee equal
to 1.5% of the gross revenues of NJ Venture. The Company expects that this
agreement will remain in place following the closing of the Offerings and the
Formation Transactions.     
 
COMPANY POLICY
 
  The Company expects to provide certain management, financial and
administrative support services to other entities controlled by Mr. McNair for
which it will receive a fee equal to estimated cost plus an appropriate
markup. Estimated cost, including office space and facilities, will be
determined on a full allocation basis, including staff time, burden and direct
charges.
 
                                      93

  To the extent that the Company makes use of corporate aircraft owned by Mr.
McNair or entities controlled by him--transactions that are likely to occur
from time to time--the Company will be charged on the basis of an estimate of
the cost of alternate transportation and on an allocation of use.
 
  All future transactions with affiliates of the Company, including the
support services to other entities controlled by Mr. McNair, will be approved
by the Board of Directors, including by a majority of the disinterested
members of the Board of Directors, pursuant to a determination by the Board of
Directors that they are on terms no less favorable to the Company than could
be obtained from unaffiliated third parties.

    Commission. In computing the number of shares of Common Stock beneficially
    owned by a person, and the percentage of ownership by that person, shares
    of Common Stock issuable pursuant to options and warrants held by that
    person that are currently exercisable or exercisable within 60 days of
          , 1998 are deemed outstanding. Such shares, however, are not deemed
    outstanding for the purpose of computing the percentage ownership of any
    other person.

    of the Formation Transactions but immediately prior to consummation of the

                         DESCRIPTION OF CAPITAL STOCK
 
  The following summary of certain provisions of the capital stock of Cogen
does not purport to be complete and is subject to, and qualified in its
entirety by, the Certificate of Incorporation (the "Charter") and the Bylaws
(the "Bylaws") of Cogen, which are included as exhibits to the Registration
Statement of which this Prospectus forms a part and by the provisions of
applicable law.
 
AUTHORIZED AND OUTSTANDING CAPITAL STOCK
 
  As of the date of this Prospectus, the authorized capital stock of Cogen
consists of 300,000,000 shares of Common Stock, par value $.01 per share
("Common Stock"), and 50,000,000 shares of Preferred Stock, par value $.01 per
share ("Preferred Stock"). As of May 21, 1998, the outstanding shares of
Common Stock were owned of record by eight stockholders. No shares of
Preferred Stock were outstanding on such date.
 
  Common Stock. The holders of Common Stock are entitled to dividends in such
amounts and at such times as may be declared by the Board of Directors out of
funds legally available therefor. The decision whether to apply legally
available funds to the payment of dividends on the Common Stock will be made
by the Board of Directors of the Company from time to time in the exercise of
its prudent business judgment, taking into account, among other things, the
Company's results of operations and financial condition, any then existing or
proposed commitments for the use by the Company of available funds, and the
Company's obligations with respect to any then outstanding class or series of
its preferred stock. In addition, the Company expects that its debt and
financing agreements will contain certain restrictions on its ability to pay
cash dividends on its capital stock. See "Dividend Policy".
 
  Holders of the Common Stock are entitled to one vote per share for the
election of directors and other corporate matters. Such holders are not
entitled to vote cumulatively for the election of directors and are not
entitled to act by written consent. In the event of liquidation, dissolution
or winding up of Cogen, holders of Common Stock would be entitled to share
ratably in all assets of Cogen available for distribution to the holders of
Common Stock. The Common Stock carries no preemptive rights. All outstanding
shares of Common Stock are duly authorized, validly issued, fully paid and
non-assessable.
 
  Preferred Stock. The Board of Directors is authorized to issue from time to
time, without stockholder authorization, in one or more designated series,
shares of Preferred Stock with such dividend, redemption, conversion and
exchange provisions as are provided in the particular series. The issuance of
Preferred Stock could have the effect of delaying or preventing a change in
control of the Company. The Board of Directors has no present plans to issue
any Preferred Stock.
 
RIGHTS PLAN
 
  Prior to the consummation of the Common Stock Offering, the Board of
Directors of the Company will declare a dividend of one common share purchase
right (a "Right") for each outstanding share of Common Stock and authorize the
issuance of one Right for each share of Common Stock which shall become
outstanding between the Record Date and the earlier of the Distribution Date
(each as hereinafter defined) or the final expiration date or redemption date
of the Rights. The dividend will be payable on              , 1998 (the
"Record Date") to the stockholders of record on that date. Each Right will
entitle the registered holder to purchase from the Company one share of Common
Stock at a price of $        per share (the "Purchase Price"), subject to
adjustment. The description and terms of the Rights are set forth in a Rights
Agreement (the "Rights Agreement") between the Company and              , as
Rights Agent (the "Rights Agent") which is included as an exhibit to the
Registration Statement of which this Prospectus forms a part.
 
  Until the earlier to occur of (i) ten business days following a public
announcement that a person or group of affiliated or associated persons (an
"Acquiring Person") has acquired beneficial ownership of 20% or more of the
outstanding shares of Common Stock or (ii) ten business days following the
commencement of, or
 
                                      97
<PAGE>
 
announcement of an intention to make, a tender offer or exchange offer the
consummation of which would result in the beneficial ownership by a person or
group of 20% or more of the outstanding shares of Common Stock (the earlier of
such dates being called the "Distribution Date"), the Rights will be evidenced
by a Common Stock certificate.
 
  Until the Distribution Date (or earlier redemption, exchange or expiration
of the Rights), Common Stock certificates issued upon transfer or new issuance
of shares of Common Stock will contain a notation incorporating the Rights
Agreement by reference. Until the Distribution Date (or earlier redemption,
exchange or expiration of the Rights), the surrender for transfer of any
certificates for shares of Common Stock outstanding will also constitute the
transfer of the Rights associated with the Common Stock represented by such
certificate. As soon as practicable following the Distribution Date, separate
certificates evidencing the Rights ("Right Certificates") will be mailed to
holders of record of Common Stock as of the close of business on the
Distribution Date, and such separate Right Certificates alone will evidence
the Rights.
 
  The Rights will not be exercisable until the Distribution Date. The Rights
will expire on          , 2008 (the "Final Expiration Date"), unless the Final
Expiration Date is extended or unless the Rights are earlier redeemed or
exchanged by the Company, in each case, as described below.
 
  The Purchase Price payable, and the number of shares of Common Stock or
other securities or property issuable, upon exercise of the Rights will be
subject to adjustment from time to time to prevent dilution (i) in the event
of a stock dividend on, or a subdivision, combination or reclassification of,
the Common Stock, (ii) upon the grant to holders of Common Stock of certain
rights or warrants to subscribe for or purchase Common Stock at a price, or
securities convertible into Common Stock with a conversion price, less than
the then current market price of the Common Stock or (iii) upon the
distribution to holders of shares of Common Stock of evidences of indebtedness
or assets (excluding regular quarterly cash dividends or dividends payable in
Common Stock) or of subscription rights or warrants (other than those referred
to above). The Company may adjust the number of Rights in substitution for any
adjustment in the number of shares of Common Stock issuable upon exercise of
each Right.
 
  In the event that (i) the Company is, in effect, acquired in a merger or
other business combination transaction or (ii) 50% or more of the Company's
consolidated assets or earning power are sold, proper provision will be made
so that each holder of a Right will thereafter generally have the right to
receive, upon the exercise thereof at the then current Purchase Price of the
Right, that number of shares of common stock of the acquiring company which at
the time of such transaction will have a market value of two times the
Purchase Price of the Right. In the event that any person becomes an Acquiring
Person, proper provision will be made so that each holder of a Right, other
than Rights beneficially owned by the Acquiring Person (which will thereafter
be void for all purposes of the Rights Agreement), will thereafter have the
right to receive upon exercise that number of shares of Common Stock having a
market value of two times the Purchase Price of the Rights. Under some
circumstances, in lieu of Common Stock, other securities, property, cash or
combinations thereof, including combinations with Common Stock, may be issued
upon payment of the Purchase Price if of equal value to the number of shares
of Common Stock for which the Right is exercisable.
 
  With certain exceptions, no adjustment in the Purchase Price will be
required until cumulative adjustments require an adjustment of at least 1% in
such Purchase Price. No fractional shares of Common Stock will be issued and
in lieu thereof, an adjustment in cash will be made based on the market price
of the Common Stock on the last trading day prior to the date of exercise.
 
  At any time up until ten business days after a public announcement that an
Acquiring Person has become such, the Board of Directors of the Company may
redeem the Rights in whole, but not in part, at a price of $.01 per Right (the
"Redemption Price"). Immediately upon any redemption of the Rights, the right
to exercise the Rights will terminate and the only right of the holders of
Rights will be to receive the Redemption Price.
 
 
                                      98
<PAGE>
 
  At any time after an Acquiring Person has become such, the Board of
Directors of the Company may exchange the Rights (other than Rights owned by
an Acquiring Person which are void), in whole or in part, at an exchange ratio
of one share of Common Stock per Right (subject to adjustment).
 
  The terms of the Rights may be amended by the Board of Directors of the
Company without the consent of the holders of the Rights at any time to cure
any ambiguity or to correct or supplement any defective or inconsistent
provisions and may, prior to the Distribution Date, be amended to change or
supplement any other provision in any manner which the Company may deem
necessary or desirable. After the Distribution Date, the terms of the Rights
may be amended (other than to cure ambiguities or correct or supplement
defective or inconsistent provisions) only so long as such amendment shall not
adversely affect the interests of the holders of the Rights (excluding an
Acquiring Person, in whose possession the Rights are void).
 
  Until a Right is exercised, the holder thereof, as such, will have no rights
as a stockholder of the Company, including, without limitation, the right to
vote or to receive dividends.
 
PROVISIONS HAVING POSSIBLE ANTI-TAKEOVER EFFECT
 
  Classified Board of Directors. The Charter will be amended prior to the
closing of the Common Stock Offering to provide that the Board of Directors
shall be divided into three classes, the members of which will serve staggered
three-year terms. The Company believes that a classified board of directors
could help to assure the continuity and stability of the Board of Directors'
and the Company's business strategies and policies. The classified board
provision could make the removal of incumbent directors more time-consuming,
which could have the effect of discouraging a third party from making a tender
offer or otherwise attempting to obtain control of the Company, even though
such an attempt might be beneficial to Cogen and its stockholders. Thus, the
classified board provision could increase the likelihood that incumbent
directors would retain their positions. In addition, the Charter provides that
directors may be removed from office only "for cause" (as defined therein).
Subject to rights of any holders of Preferred Stock, newly created directors
and vacancies on the Board of Directors will be filled solely by the remaining
directors then in office.
 
  Advance Notice Provisions for Certain Stockholder Actions. The Bylaws
establish an advance notice procedure with regard to the nomination, other
than by or at the direction of the Board of Directors, of candidates for
election as directors (the "Nomination Procedure") and with regard to certain
matters to be brought before an annual meeting of stockholders of Cogen (the
"Business Procedure").
 
  The Nomination Procedure requires that a stockholder give prior written
notice, in proper form, of a planned nomination of a director to the Board of
Directors to the Secretary of Cogen. The requirements as to the form and
timing of that notice are specified in the Bylaws. If it is determined that a
person was not nominated in accordance with the Nomination Procedure, such
person will not be eligible for election as a director.
 
  Under the Business Procedure, a stockholder seeking to have any business
conducted at an annual meeting must give prior written notice, in proper form,
to the Secretary of Cogen. The requirements as to the form and timing of that
notice are specified in the Bylaws and are also governed by federal securities
law proxy rules. If the Chairman or other officer presiding at a meeting
determines that other business was not properly brought before such meeting in
accordance with the Business Procedure, such business will not be conducted at
the meeting.
 
  Although the Bylaws do not give the Board any power to approve or disapprove
stockholder nominations for the election of directors or of any other business
desired by stockholders to be conducted at an annual or any other meeting, the
Bylaws (i) may have the effect of precluding a nomination for the election of
directors or precluding the conduct of business at a particular annual meeting
if the proper procedures are not followed, and (ii) may discourage or deter a
third party from conducting a solicitation of proxies to elect its own slate
of directors or otherwise attempting to obtain control of the Company, even if
the conduct of such solicitation or such attempt might be beneficial to the
Company and its stockholders.

  Delaware Section 203. Section 203 ("Section 203") of the General Corporation
Law of the State of Delaware (the "Delaware Act") restricts certain
transactions between a corporation organized under Delaware law (or its
majority-owned subsidiaries) and any person holding 15% or more of the
corporation's outstanding voting stock, together with the affiliates or
associates of such person (an "Interested Stockholder"). Section 203 generally
prohibits a publicly held Delaware corporation from engaging in the following
transactions with an Interested Stockholder for a period of three years from
the time the stockholder becomes an Interested Stockholder (unless certain
conditions, described below, are met): (a) all mergers or consolidations, (b)
sales, leases, exchanges or other transfers of 10% or more of the aggregate
assets of the corporation, (c) issuances or transfers by the corporation of
any stock of the corporation which would have the effect of increasing the
Interested Stockholder's proportionate share of the stock of any class or
series of the corporation, (d) any other transaction which has the effect of
increasing the proportionate share of the stock of any class or series of the
corporation which is owned by the Interested Stockholder, and (e) receipt by
the Interested Stockholder of the benefit (except proportionately as a
stockholder) of loans, advances, guarantees, pledges or other financial
benefits provided by the corporation.
 
  The three-year ban does not apply if either (i) the proposed prohibited
transaction or (ii) the transaction by which the Interested Stockholder became
an Interested Stockholder is approved by the board of directors of the
corporation prior to the time such stockholder becomes an Interested
Stockholder. Additionally, an Interested Stockholder may avoid the statutory
restriction if, upon the consummation of the transaction whereby such
stockholder becomes an Interested Stockholder, the stockholder owns at least
85% of the outstanding voting stock of the corporation without regard to those
shares owned by the corporation's officers and directors or certain employee
stock plans. Business combinations are also permitted within the three-year
period if approved by the board of directors and authorized at an annual or
special meeting of stockholders by the holders of at least 66 2/3% of the
outstanding voting stock not owned by the Interested Stockholder. In addition,
any transaction is exempt from the statutory ban if it is proposed at a time
when the corporation has proposed, and a majority of certain continuing
directors of the corporation have approved, a transaction with a party which
is not an Interested Stockholder of the corporation (or who becomes such with
board approval) if the proposed transaction involves (a) certain mergers or
consolidations involving the corporation, (b) a sale or other transfer of over
50% of the aggregate assets of the corporation or (c) a tender or exchange
offer for 50% or more of the outstanding voting stock of the corporation.
 
  A Delaware corporation may, at its option, exclude itself from the coverage
of Section 203 by amending its Certificate of Incorporation or Bylaws by
action of its stockholders to exempt itself from coverage, provided that such
charter or bylaw amendment shall not become effective until 12 months after
the date it is adopted. Cogen has not adopted such a charter or bylaw
amendment.
 
  The foregoing provisions of Section 203 could delay or frustrate the removal
of incumbent directors or the assumption of control by the holder of a large
block of Common Stock, even if such removal or assumption would be beneficial,
in the short term, to stockholders of the Company. The provisions could also
discourage or make more difficult a merger, tender offer or proxy contest even
if such event would be favorable to the interests of stockholders.
 
LIMITATION ON DIRECTORS AND OFFICERS LIABILITY
 
  The Delaware Act authorizes corporations to limit or eliminate the personal
liability of directors to corporations and their stockholders for monetary
damages for breach of directors' fiduciary duty of care. The duty of care
requires that, when acting on behalf of the corporation, directors must
exercise an informed business judgment based on all material information
reasonably available to them. Absent the limitations authorized by such
legislation, directors are accountable to corporations and their stockholders
for monetary damages for conduct constituting gross negligence in the exercise
of their duty of care and for certain failures to properly supervise the
affairs of the corporation. Although the Delaware Act does not change
directors' duty of care, it enables corporations to limit available relief to
equitable remedies such as injunction or rescission. The Charter limits the
liability of Cogen's directors to Cogen or its stockholders to the fullest
extent permitted by the
 
                                      100
<PAGE>
 
Delaware Act. Specifically, directors of Cogen will not be personally liable
for monetary damages for breach by directors of their fiduciary duty as
directors, except for liability (i) for any breach of the directors' duty of
loyalty to the Company or its stockholders, (ii) for acts or omissions not in
good faith or which involve intentional misconduct or a knowing violation of
law, (iii) under Section 174 of the Delaware Act (having to do with unlawful
distributions to stockholders or unlawful purchases or redemptions of its
shares by Cogen), or (iv) for any transaction from which the director derived
an improper personal benefit.
 
  The inclusion of this provision in the Charter may have the effect of
reducing the likelihood of derivative litigation against directors and may
discourage or deter stockholders or management from bringing a lawsuit against
directors for breach of their duty of care, even though such an action, if
successful, might otherwise have benefitted Cogen and its stockholders.

          DESCRIPTION OF SENIOR NOTES AND CERTAIN OTHER INDEBTEDNESS
 
DESCRIPTION OF SENIOR NOTES
 
  Concurrently with the Common Stock Offering, the Company is offering up to
$400.0 million aggregate principal amount of Senior Notes, pursuant to the
Debt Offering. The following discussion summarizes certain terms of the Senior
Notes and is qualified in its entirety by reference to the Indenture relating
to the Senior Notes.
 
  The Senior Notes will be senior secured obligations of the Company and will
rank pari passu in right of payment with all existing and future senior
indebtedness of Cogen, including Cogen's obligations under the Revolving
Credit Facility, and senior in right of payment to all existing and future
subordinated debt of the Company. The Senior Notes will mature in three
tranches and will bear interest from the date of issuance at the rates of
   %,    % and    %, respectively, per annum payable semi-annually.
 
  The Senior Notes will be secured, on a pari passu basis, by a security
interest granted by Cogen in a portion of the equity interests of Cogen in
certain of its direct, wholly-owned subsidiaries, which subsidiaries own the
equity interests of Cogen in each of Linden Venture, Camden Cogen and NJ
Venture, which, in turn, own, indirectly, interests in the partnership
interests in each of the Linden, Camden and Bayonne Ventures, respectively. In
no event will such security interest encumber any such venture or the general
partner of any such venture, or any of their respective rights or properties.
 
  The Senior Notes will be redeemable at the option of Cogen, in whole or in
part, at any time or from time to time, at the Redemption Price (as defined in
the First Supplemental Indenture). Prior to the Covenant Modification Date (as
defined below), the Senior Notes will be subject to mandatory redemption (at
the Redemption Price in the case of clauses (ii) and (iii) below) in each of
the following instances, after giving effect to the required repayment of
indebtedness of such NJ Partnership and of its Managing General Partner, in
each case, outstanding on the Issue Date, and to fund accounts or otherwise be
subject to restrictions on distributions by the lenders of such indebtedness,
and the required distributions to other partners and venturers of such NJ
Partnership: (i) if an NJ Partnership or Cogen (on behalf of such NJ
Partnership) receives net proceeds, cash or non-cash, in excess of $50.0
million with respect to one or more events of loss or condemnation with
respect to the property of such NJ Partnership and, after reduction of such
amount by the aggregate amount of all of such proceeds used toward the
restoration, repair, re-construction or replacement of such property, the
remaining aggregate amount of the cash or non-cash proceeds exceeds $50.0
million; (ii) if an NJ Partnership or Cogen (on behalf of such NJ Partnership)
receives at any time following the date of the issuance of the Senior Notes an
aggregate amount of net proceeds in excess of $100.0 million from one or more
payments by an electricity purchaser or steam purchaser in connection with the
buyout of a power purchase agreement or steam sales agreement; and (iii) if
Cogen sells, transfers, assigns or otherwise disposes of any NJ Partnership,
or any interest therein, or any NJ Partnership sells, transfers, assigns or
otherwise disposes of assets owned by such NJ Partnership, in one or more
transactions, whose net proceeds, cash and non-cash, exceed $100.0 million
(exclusive of certain dispositions set forth in the Indenture); unless, in
each instance, after giving effect to such occurrence and the use or
contemplated use of the proceeds therefrom as announced by Cogen, the Rating
Agencies (as defined in the First Supplemental Indenture) confirm the then
current ratings on the Senior Notes. On and after the Covenant Modification
Date, the Senior Notes will not be subject to mandatory redemption.
 
  The First Supplemental Indenture will contain certain restrictive covenants
of Cogen and the NJ Partnerships that limit the ability of Cogen and the NJ
Partnerships to: (i) as to Cogen, incur certain additional indebtedness (as
defined herein) other than (a) the Senior Notes and other indebtedness under
the Indenture (excluding debt securities subsequently issued thereunder), (b)
Indebtedness incurred pursuant to the Revolving Credit Facility in an
aggregate amount not to exceed $300.0 million at any one time outstanding, (c)
Indebtedness incurred pursuant to the Linden Guarantee (as defined herein),
(d) Indebtedness ranking pari passu in right of payment with the Senior Notes
and the Revolving Credit Facility, the incurrence of which either is incurred
in compliance with a debt coverage ratio or will not result in a downgrading
of the then current ratings of the Senior Notes, (e) Subordinated Indebtedness
(as defined herein) and (f) Indebtedness incurred to refinance, renew,
 
                                      102
<PAGE>
 
replace, defease or refund, in whole or in part, any Indebtedness specified in
the preceding clauses (a) through (e); and (ii) as to the NJ Partnerships,
incur certain Indebtedness other than (a) $[  ] of Indebtedness outstanding on
the Issue Date, (b) Indebtedness in an aggregate amount not to exceed $100
million at any one time outstanding for improvements and expansions to any or
all of the NJ Plants and (c) other Indebtedness required to satisfy any
fiduciary responsibilities of the partners or venturers, as applicable, of
each of the NJ Partnerships. In addition, the First Supplemental Indenture
will permit Cogen to make dividend payments or other distributions equal to
the sum of 100% of Funds From Operations (as defined herein) (from the Issue
Date) plus $50 million, unless a Default or Event of Default has occurred and
is continuing. Upon the Covenant Modification Date, and without any further
action or step taken by any Person or requirement of any nature being
satisfied, the foregoing covenants will immediately and forever terminate and
cease to be operative.
   
  The Covenant Modification Date shall mean the day that (i) Cogen has a
portfolio comprised of interests in at least eight power projects with no
single project contributing more than 25% or less than 5% of aggregate Cash
Distributions (as defined in the Indenture) for each of the four quarters
preceding such date of determination and the four quarters succeeding such
date of determination (as projected by Cogen), as certified by both the
Independent Engineer (as defined in the First Supplemental Indenture) and
Cogen's Chief Financial Officer (with forecasts relating to merchant capacity
reflecting cash flows for such capacity over the previous four quarters) and
(ii) the Senior Notes are rated at least investment grade by the Rating
Agencies.     
 
  The Indenture and First Supplemental Indenture governing the Senior Notes
also will contain certain covenants of Cogen that, among other things, limit
the ability of Cogen and its subsidiaries to create liens or enter into sale
and leaseback transactions and limit the ability of Cogen to engage in mergers
and consolidations or transfer all or substantially all of its assets.
 
BRIDGE LOAN
   
  Immediately prior to the consummation of the Formation Transactions and
Common Stock Offering, Morgan Stanley & Co. Incorporated ("Morgan Stanley")
will loan $291.0 million to Linden Ltd. pursuant to the Bridge Loan, which
Linden Ltd. will use to redeem the 50.1% of the equity interests in Linden
Ltd. owned by the McNair Interests and the Minority Interests. See "Certain
Transactions--Formation Transactions". The Bridge Loan will be evidenced by a
subordinated promissory note in favor of Morgan Stanley, which note will bear
interest at the rate of 24% per annum. Immediately following the consummation
of the Debt Offering, Cogen will loan $291.0 million of the proceeds of the
Debt Offering to Linden Ltd. for repayment of the Bridge Loan.     
 
PLANT PROJECT FINANCINGS
   
  Linden Venture. Linden Venture has no outstanding project financing
indebtedness. The construction lender to Linden Venture contributed the
outstanding construction loan balance in exchange for a limited partnership
interest in Linden Venture. Pursuant to the terms of the partnership agreement
relating to Linden Venture, the limited partner is entitled to receive
distributions of Linden Venture Distributable Cash on a basis preferential to
the interest of Linden Ltd., which is the general partner of Linden Venture;
the limited partner receives 99% of the Linden Venture Distributable Cash
until it has received a pre-determined amount, and thereafter, Linden, Ltd.
receives a substantially increased percentage of the Linden Venture
Distributable Cash. See "Existing Venture and Plant Descriptions--Linden Cash
Distributions".     
   
  At June 30, 1998, a $10.0 million letter of credit issued by GECC for the
account of Linden Venture in favor of Bayway Refinery (the "Bayway L/C") was
outstanding pursuant to a September 17, 1992 letter of credit facility between
Linden Venture and GECC. The Bayway L/C expires August 1, 1999. The monthly
fee payable by Linden Venture for this facility is 0.75% per annum on the face
amount of the outstanding letters of credit. Linden Venture's reimbursement
obligation under this facility is unsecured. Linden Venture has no
indebtedness other than its reimbursement obligations under the GECC letter of
credit facility.

  Pursuant to the Linden GP Term Loan Agreement between Linden Ltd. and the
Owner Trust, and as of June 30, 1998, Linden Ltd. is indebted to the Owner
Trust in a principal amount of $212.0 million, which indebtedness is secured
by its general partnership interest in Linden Venture and, as described below,
certain segregated deposit accounts created with the revenue of Linden
Venture. The proceeds of the Linden GP Term Loan were used for working capital
($10.0 million), as the equity contribution of Linden Ltd. in Linden Venture
($25.0 million) and as loans to a company owned by the McNair Interests and
the Minority Interests that is not a part of the Company, Financial Services.
The Linden GP Term Loan comprises a fixed rate portion, a floating rate
portion and a working capital portion, all of which mature September 1, 2007.
At June 30, 1998, $96.8 million was outstanding under the fixed rate portion,
$105.2 million was outstanding under the floating rate portion, and $10.0
million was outstanding under the working capital portion. The fixed rate
portion bears interest at 8.8% with principal and interest payments due
quarterly. Principal payments with respect to the fixed rate portion increase
by 2.85% each quarter with the principal payment due September 1, 1998 being
$1.5 million, and the final principal payment being $4.1 million. The floating
rate portion bears interest at LIBOR plus 1.65%, with principal and interest
payments due quarterly. Principal payments with respect to the floating rate
portion increase by 2.85% each quarter, with the principal payment due
September 1, 1998 being $1.6 million, and the final principal payment being
$4.5 million. The working capital portion bears interest at the one month,
financial commercial paper rate (as reported in Federal Statistical Release
H.15 (519) or successor publication) plus 0.55%, with interest payable
quarterly. The principal with respect to the working capital portion is due
September 1, 2007. All such borrowings are secured by Linden Ltd.'s
partnership interest in Linden Venture. Linden Ltd. cannot make further
borrowings under the Linden GP Term Loan Agreement. See "Existing Venture and
Plant Descriptions--Linden General Partner Term Loan".     
 
  The Linden GP Term Loan Agreement contains certain restrictions that
significantly limit or prohibit, among other things, the ability of Linden
Ltd. to incur indebtedness, make payments of certain indebtedness, pay
distributions to its owners, make investments, engage in transactions with
affiliates, create liens, sell assets and engage in acquisitions, mergers and
consolidations.
 
  Pursuant to the terms of a security deposit agreement among Linden Venture,
Linden Ltd., the Owner Trust, as limited partner and as lender, and a
financial institution as security agent and escrow agent, Linden Venture has
agreed that a portion of Linden Venture's revenues will be deposited in, among
other accounts, a segregated deposit account for the debt service and ratio
requirements of the Linden GP Term Loan, which deposit is made prior to any
distributions of amounts to owners of Linden Venture, and a segregated account
for amounts to be distributed to its owners. See "Existing Venture and Plant
Descriptions--Linden Cash Distributions". Further pursuant to such security
deposit agreement, Linden Ltd. has pledged its rights in the preceding-
described accounts to secure the Linden GP Term Loans.
 
  The effect of the Owner Trust's prior right to Linden Venture Distributable
Cash and the depositary arrangement described in the immediately preceding
paragraph is that the Company's rights (and, consequently, the Company's
creditors' and shareholders' rights) to Linden Venture Distributable Cash and
the cash deposited in the accounts governed by the security deposit agreement
are subordinated to the Owner Trust's and the Linden Ltd. term lender's
respective rights therein. In addition, while there is no indebtedness on
Linden Venture's balance sheet, the Linden Venture partnership agreement
contains certain provisions that effectively restrict Linden Venture from,
among other things, entering into certain agreements or commitments, selling
or otherwise transferring assets, incurring indebtedness (other than defined
permitted indebtedness), creating or allowing any lien on its property (other
than defined permitted liens) and amending or modifying project documents.
   
  Camden Cogen. Pursuant to the Camden Cogen Term Loan Agreement, and as of
June 30, 1998, Camden Cogen had $87.5 million of outstanding non-recourse
project financing term indebtedness from GECC and a syndication of
international banks, which indebtedness is secured by the Camden Plant and the
other Camden Cogen assets, revenues of Camden Cogen, the general partnership
interest of Camden GPLP, and the general partnership interest in Camden GPLP
owned by Cogen Technologies Camden, Inc. ("Camden Inc."), the general partner
of Camden GPLP and a subsidiary of the Company. Of such outstanding
indebtedness, $63.9 million represents the Camden Tranche A Loan, which
matures May 2007 and accrues interest at the per annum rate of either (i) 3-
month LIBOR plus an increasing margin of 1.00 to 1.625% (1.25% for the period
November 3, 1998     
 
                                      104

to November 1, 2001) or (ii) if such loan is in default, the Bank of Tokyo
Trust prime rate (which has an increasing margin of .375% to 1.0%) plus 2.0%
or the fed funds rate (which has a margin of 0.5%) plus 2.0%, whichever is
higher, with principal and interest payable quarterly. Principal payments with
respect to the Camden Tranche A Loan increase each quarter by varying amounts
ranging from approximately 1.5% to approximately 5.5% of the prior quarter's
payment with the principal payment due November 1, 1998 being $1.2 million,
and the final principal payment being $2.5 million. Camden Cogen has entered
into an interest rate swap agreement with GECC which effectively fixes the
interest rate with respect to the Camden Tranche A Loan at 5.945%. The swap
agreement has a notional amount equal at all times to the outstanding
principal balance of the Camden Tranche A Loan. The remaining portion of this
indebtedness, $23.6 million, represents the Camden Tranche B Loan, which
matures in May 2009 and accrues interest at the per annum rate of 11.4%, with
interest and principal payable quarterly. Principal payments with respect to
the Camden Tranche B Loan increase each quarter by varying amounts ranging
from approximately 1.6% to approximately 4.0% of the prior quarter's payment,
with the principal payment due November 1, 1998 being $0.2 million, and the
final principal payment being $1.4 million. Optional prepayments on the Camden
Tranche B Loan are subject to a yield maintenance premium.     
 
  The Camden Cogen Term Loan Agreement contains certain restrictions that
significantly limit or prohibit, among other things, the ability of Camden
Cogen or its general partner, Camden GPLP, to incur indebtedness, make
payments of certain indebtedness, pay distributions to its owners, make
investments, engage in transactions with affiliates, create liens, sell
assets, amend material contracts and engage in acquisitions, mergers and
consolidations. In addition, the Camden Cogen Term Loan Agreement requires
Camden Cogen to establish and maintain security deposit accounts with a
financial institution into which its revenues are deposited and from which
reserve accounts are funded and maintained for various obligations, including
the repayment of the Camden Cogen Term Loans, the Camden Cogen letter of
credit facility and the Camden GP Term Loans. See "Existing Venture and Plant
Descriptions--Camden Cash Distributions".
   
  At June 30, 1998, a standby letter of credit issued by GECC for the account
of Camden Cogen was outstanding in the aggregate amount of $4.8 million, for
the purpose of securing certain of its reserve account obligations on the
Camden Tranche A Loan. No fee is payable by Camden Cogen for such outstanding
letter of credit, which expires in May 2007. Camden Cogen's reimbursement
obligations under this letter of credit are secured by the same collateral
that secures the Camden Cogen Term Loans.     
 
  Pursuant to the terms of Camden Cogen's partnership agreement, the limited
partner is entitled to receive distributions on a basis preferential to the
interest of Camden GPLP. See "Existing Venture and Plant Description--Camden
Cash Distributions".
   
  Pursuant to the Camden GP Term Loan Agreement between Camden GPLP and GECC,
and as of June 30, 1998, Camden GPLP is indebted to GECC in the principal
amount of $12.7 million, which indebtedness is secured by its general
partnership interest in Camden Cogen, the general partnership interest in
Camden GPLP of its general partner, Camden Inc., and a portion of Camden Cogen
revenues committed to a corresponding reserve account. This term indebtedness
matures May 2010. Interest on this term indebtedness accrues at either a fixed
rate or a floating rate. The fixed rate is a per annum rate based upon the 10-
year Treasury rate plus 5%, and the floating rate is a per annum rate of
either (i) Citibank prime plus 3% or (ii) LIBOR plus 4.25%. Interest accruing
at the prime rate or the fixed rate is payable monthly, and interest accruing
at the LIBOR rate is payable on the last day of a relevant interest period.
Principal payments are determined on a quarterly basis and made monthly in an
amount equal to one-third of the quarterly amount. The quarterly amount
increases each quarter by approximately 2.6% of the prior quarterly amount.
Principal payments for the quarter ended November 1, 1998 total $0.1 million,
and principal payments for the final quarterly period total $0.5 million.
Optional prepayments on portions of the indebtedness accruing interest at the
fixed rate are subject to the payment of a yield maintenance premium, and
optional prepayments on portions of the indebtedness accruing interest at a
floating rate which are made during the period from April 1996 to April 2000
are subject to the payment of a premium on the prepaid portion thereof
calculated at an annually decreasing percentage which begins at 4%. Camden
GPLP cannot make further borrowings under the Camden GP Term Loan Agreement
pursuant to which this term indebtedness was incurred.

  The Camden GP Term Loan Agreement contains certain restrictions that
significantly limit or prohibit, among other things, the ability of the Camden
GPLP to incur indebtedness, make payments of certain indebtedness, pay
distributions to its owners, make investments, engage in transactions with
affiliates, create liens, sell assets and engage in acquisitions, mergers and
consolidations.
 
  The effect of the foregoing financing arrangements regarding Camden Cogen
and Camden GPLP is that the Company's rights (and, consequently, the Company's
creditors' and shareholders' rights) to Camden Cogen Distributable Cash and
the cash deposited in the above-described security deposit accounts are
subordinated to the rights of Camden Cogen's and Camden GPLP's lenders'
respective rights therein.
   
  NJ Venture. Pursuant to the Prudential Loan Agreement and as of June 30,
1998, NJ Venture had $69.8 million of outstanding, non-recourse term project
financing indebtedness from Prudential, which is secured by the Bayonne Plant
and other NJ Venture assets and all revenues of NJ Venture. This indebtedness
matures October 2008 and accrues interest at the per annum rate of 10.85%,
with accrued interest and principal payable quarterly. The Prudential Term
Loan is non-callable through September 2002, and thereafter may, at the option
of NJ Venture, be prepaid at a premium on the prepaid portion thereof
calculated at a decreasing percentage which commences at 10.85%.     
 
  The Prudential Loan Agreement contains certain restrictions that
significantly limit or prohibit, among other things, the ability of NJ Venture
to incur indebtedness, make payments of certain indebtedness, pay
distributions to its owners, make investments, engage in transactions with
affiliates, create liens, sell assets and engage in acquisitions, mergers and
consolidations. In addition, the Prudential Loan Agreement requires NJ Venture
to create a debt service reserve fund from net cash flow if NJ Venture's
annual debt service coverage ratio, calculated each quarter using the previous
twelve months' financial information, falls below 1.50x. NJ Venture must
increase the reserve until funds held in such reserve plus the funds available
for debt service equal 1.50x the previous twelve months' debt service. Any
funds held in such reserve may be released as, and to the extent that, the
balance of funds retained in such reserve (if any) together with NJ Venture's
net cash flow cause NJ Venture's coverage ratio to exceed 1.50x. Such annual
debt service coverage ratio has not been below 1.50x, and as a result, NJ
Venture has not been required to fund the debt service reserve. At December
31, 1997, NJ Venture's debt service coverage ratio as calculated under the
Prudential Loan Agreement was 1.84x.
   
  Pursuant to the Equipment Loan Agreement and as of June 30, 1998, NJ Venture
is indebted to the Bayonne Equipment Lender in the principal amount of $0.2
million and an additional amount for accrued interest of $0.2 million. Such
outstanding principal amount and accrued interest thereon mature the earlier
of May 22, 1999 and the execution of a new steam sale agreement. The
obligations under the Equipment Loan Agreement are secured by the equipment
purchased by NJ Venture in connection with such agreement, and the payment of
the interest that has accrued and continues to accrue on the remaining
principal balance is non recourse to NJ Venture, it being limited to the
security for the loan.     
   
  At June 30, 1998, NJ Venture had $1.5 million outstanding under the $5.0
million Revolving Facility with SBT, which was established by it for short
term working capital requirements and expires December 1998. Borrowings under
the Revolving Facility are payable at the expiration of the facility and
accrue interest at the per annum rate of 0.5% below SBT prime, with accrued
interest being payable monthly, and are secured by rights to payments from NJ
Venture power purchase agreements. NJ Venture pays a commitment fee of 1/4 of
1% on the average unused principal balance of the Revolving Facility. In
addition, at June 30, 1998, a standby letter of credit issued by the UBS for
the account of NJ Venture in the amount of $4.6 million was outstanding for
the purpose of securing certain obligations of NJ Venture to PSE&G pursuant to
a tracking account arrangement. See "Existing Venture and Plant Descriptions--
Bayonne Power Purchase Agreement--PSE&G". The letter of credit was procured
for NJ Venture by Financial Services. NJ Venture pays a quarterly fee on such
letter of credit calculated at 0.3% per annum on the face amount of the letter
of credit to the issuer thereof. Financial Services has the reimbursement
obligations to such issuer in the event any drawing is made on the letter of
credit. Pursuant to agreement between NJ Venture and Financial Services, NJ
Venture agrees to reimburse Financial Services for all fees and reimbursement
obligations incurred by Financial Services under the letter of credit, which
obligation of NJ Venture is unsecured. Such letter of credit expires May 1999.

                        SHARES ELIGIBLE FOR FUTURE SALE
 
  Prior to completion of the Common Stock Offering, there has been no public
market for the Common Stock. Sales of substantial amounts of Common Stock in
the public market, or the perception that such sales may occur, could have an
adverse effect on the price of the Common Stock.
 
  Upon completion of the Common Stock Offering, the Company will have
outstanding 55,000,000 shares of Common Stock. Of such shares, 21,666,667
shares of Common Stock are considered "restricted securities" for the purpose
of Rule 144 under the Securities Act and may only be sold if they are
registered under the Securities Act or if an exemption from registration is
available, including an exemption afforded by Rule 144 under the Securities
Act.
 
  In general, under Rule 144, as currently in effect, a person (or person
whose shares are aggregated), including an affiliate of the Company, who has
beneficially owned his or her restricted securities for at least one year but
less than two years, is entitled to sell within any three-month period a
number of such shares that does not exceed the greater of (i) 1% of the then
outstanding shares of Common Stock or (ii) the average weekly trading volume
in the Common Stock during the four calendar weeks preceding the date on which
notice of such sale is filed with the Commission. Sales pursuant to Rule 144
are subject to certain requirements relating to manner of sale, notice, and
availability of current public information about the Company. A person who is
not deemed to have been an affiliate of the Company at any time during the
three months preceding a sale, and who owns shares that have not been held by
the Company or an affiliate of the Company for at least two years, would be
entitled to sell the shares under Rule 144(k) without compliance with the
limitations described above. Restricted securities properly sold in reliance
on Rule 144 are thereafter freely tradeable without restrictions or
registration under the Securities Act unless thereafter held by an affiliate
of the Company.
   
  The holders of 21,700,000 shares of Common Stock have certain rights to
require Cogen to register sales of such shares under the Securities Act,
subject to certain restrictions, if, subsequent to the consummation of the
Common Stock Offering, Cogen proposes to register any of its securities under
the Securities Act. Such holders are entitled to notice of such registration
and to include their shares in such registration with their expenses borne by
Cogen, subject to the right of an underwriter participating in the offering to
limit the number of shares included in such registration. In addition, of such
holders the holders of 16,425,000 shares of Common Stock, have the right to
demand, on two occasions, that Cogen file a registration statement covering
sales of their respective shares, and Cogen is obligated to pay the expenses
of such registrations. Some of the shares as to which registration rights
exist are subject to the Underwriters' over-allotment option.     
 
  Each of the Company, the Selling Stockholders and the directors and
executive officers of the Company has agreed that, without the prior written
consent of Morgan Stanley & Co. Incorporated on behalf of the Underwriters, it
will not, during the period ending 180 days after the date of this Prospectus,
(i) offer, pledge, sell, contract to sell, sell any option or contract to
purchase, purchase any option or contract to sell, grant any option, right or
warrant to purchase, lend or otherwise transfer or dispose of, directly or
indirectly, any shares of Common Stock or any securities convertible into or
exercisable or exchangeable for Common Stock or (ii) enter into any swap or
other arrangement that transfers to another, in whole or in part, any of the
economic consequences of ownership of the Common Stock, subject to limited
exceptions. See "Underwriters."
 
  No prediction can be made as to the effect, if any, that future sales of
shares, or the availability of shares for future sale, will have on the market
price of the Common Stock prevailing from time to time. Sales of substantial
amounts of Common Stock (including shares issued upon the exercise of stock
options), or the perception that such sales could occur, could adversely
affect prevailing market prices for the Common Stock. If such sales reduce the
market price of the Common Stock, the Company's ability to raise additional
capital in the equity markets could be adversely affected.

  The U.S. Underwriters and the International Underwriters, and the U.S.
Representatives and the International Representatives, are collectively
referred to as the "Underwriters" and the "Representatives", respectively. The
Underwriting Agreement provides that the obligations of the several
Underwriters to pay for and accept delivery of the shares of Common Stock
offered hereby are subject to the approval of certain legal matters by their
counsel and to certain other conditions. The Underwriters are obligated to
take and pay for all of the shares of Common Stock offered hereby (other than
those covered by the Underwriters' overallotment option described below) if
any such shares are taken.
 
  Pursuant to the Agreement between U.S. and International Underwriters, each
U.S. Underwriter has represented and agreed that, with certain exceptions: (i)
it is not purchasing any Shares (as defined herein) for the account of anyone
other than a United States or Canadian Person (as defined herein) and (ii) it
has not offered or sold, and will not offer or sell, directly or indirectly,
any Shares or distribute any prospectus relating to the Shares outside the
United States or Canada or to anyone other than a United States or Canadian
Person. Pursuant to the Agreement between U.S. and International Underwriters,
each International Underwriter has represented and agreed that, with certain
exceptions: (i) it is not purchasing any Shares for the account of any United
States or Canadian Person and (ii) it has not offered or sold, and will not
offer or sell, directly or indirectly, any Shares or distribute any prospectus
relating to the Shares in the United States or Canada or to any United States
or Canadian Person. With respect to any Underwriter that is a U.S. Underwriter
and an International Underwriter, the foregoing representations and agreements
(i) made by it in its capacity as a U.S. Underwriter apply only to it in its
capacity as a U.S. Underwriter and (ii) made by it in its capacity as an
International Underwriter apply only to it in its capacity as an International
Underwriter. The foregoing limitations do not apply to stabilization
transactions or to certain other transactions specified in the Agreement
between U.S. and International Underwriters. As used herein, "United States or
Canadian Person" means any national or resident of the United States or
Canada, or any corporation, pension, profit-sharing or other trust or other
entity organized under the
 
                                      108

laws of the United States or Canada or of any political subdivision thereof
(other than a branch located outside the United States and Canada of any
United States or Canadian Person), and includes any United States or Canadian
branch of a person who is otherwise not a United States or Canadian Person.
All shares of Common Stock to be purchased by the Underwriters under the
Underwriting Agreement are referred to herein as the "Shares".
 
  Pursuant to the Agreement between U.S. and International Underwriters, sales
may be made between the U.S. Underwriters and International Underwriters of
any number of Shares as may be mutually agreed. The per share price of any
Shares so sold shall be the public offering price set forth on the cover page
hereof, in United States dollars, less an amount not greater than the per
share amount of the concession to dealers set forth below.
 
  Pursuant to the Agreement between U.S. and International Underwriters, each
U.S. Underwriter has represented that it has not offered or sold, and has
agreed not to offer or sell, any Shares, directly or indirectly, in any
province or territory of Canada or to, or for the benefit of any resident of
any province or territory of Canada in contravention of the securities laws
thereof and has represented that any offer or sale of Shares in Canada will be
made only pursuant to an exemption from the requirement to file a prospectus
in the province or territory of Canada in which such offer or sale is made.
Each U.S. Underwriter has further agreed to send to any dealer who purchases
from it any of the Shares a notice stating in substance that, by purchasing
such Shares, such dealer represents and agrees that it has not offered or
sold, and will not offer or sell, directly or indirectly, any of such Shares
in any province or territory of Canada or to, or for the benefit of, any
resident of any province or territory of Canada in contravention of the
securities laws thereof and that any offer or sale of Shares in Canada will be
made only pursuant to an exemption to file a prospectus in the province or
territory of Canada in which such offer or sale is made, and that such dealer
will deliver to any other dealer to whom it sells any of such Shares a notice
containing substantially the same statement as is contained in this sentence.
 
  Pursuant to the Agreement between U.S. and International Underwriters, each
International Underwriter has represented and agreed that (i) it has not
offered or sold and, prior to the date six months after the closing date for
the sale of the Shares to the International Underwriters, will not offer or
sell any Shares to persons in the United Kingdom except to persons whose
ordinary activities involve them in acquiring, holding, managing or disposing
of investments (as principal or agent) for the purpose of their business or
otherwise in circumstances which have not resulted and will not result in an
offer to the public in the United Kingdom within the meaning of the Public
Offers of Securities Regulations (1995); (ii) it has complied and will comply
with all applicable provisions of the Financial Services Act 1986 with respect
to anything done by it in relation to the Shares in, from or otherwise
involving the United Kingdom; and (iii) it has only issued or passed on and
will only issue or pass on in the United Kingdom any document received by it
in connection with the offering of the Shares to a person who is of a kind
described in Article 11(3) of the Financial Services Act 1986 (Investment
Advertisements) (Exemptions) Order 1996, or is a person to whom such document
may otherwise lawfully be issued or passed on.
 
  Pursuant to the Agreement between U.S. and International Underwriters, each
International Underwriter has further represented that it has not offered or
sold, and has agreed not to offer or sell, directly or indirectly, in Japan or
to or for the account of any resident thereof, any of the Shares acquired in
connection with the distribution contemplated hereby, except for offers or
sales to Japanese International Underwriters or dealers and except pursuant to
any exemption from the registration requirements of the Securities and
Exchange Law and otherwise in compliance with applicable provisions of
Japanese law. Each International Underwriter has further agreed to send to any
dealer who purchases from it any of the Shares a notice stating in substance
that, by purchasing such Shares, such dealer represents and agrees that it has
not offered or sold, and will not offer or sell, any of such Shares, directly
or indirectly, in Japan or to or for the account of any resident thereof
except for offers or sales to Japanese International Underwriters or dealers
and except pursuant to any exemption from the registration requirements of the
Securities and Exchange Law and otherwise in compliance with applicable
provisions of Japanese law, and that such dealer will send to any other dealer
to whom it sells any of such Shares a notice containing substantially the same
statement as is contained in this sentence.

  The Underwriters initially propose to offer part of the shares of Common
Stock directly to the public at the public offering price set forth on the
cover page hereof and part to certain dealers at a price which represents a
concession not in excess of $.   per share under the public offering price.
Any Underwriter may allow, and such dealers may re-allow, a concession not in
excess of $.   per share to other Underwriters or to certain other dealers.
After the initial offering of the shares of Common Stock, the offering price
and other selling terms may from time to time be varied by the
Representatives.
 
  Pursuant to the Underwriting Agreement, certain Selling Stockholders have
granted to the U.S. Underwriters an option, exercisable for 30 days from the
date of this Prospectus, to purchase up to an aggregate of
additional shares of Common Stock at the public offering price set forth on
the cover page hereof, less underwriting discounts and commissions. The U.S.
Underwriters may exercise such option to purchase solely for the purpose of
covering overallotments, if any, made in connection with the offering of the
shares of Common Stock offered hereby. To the extent such option is exercised,
each U.S. Underwriter will become obligated, subject to certain conditions, to
purchase approximately the same percentage of such additional shares of Common
Stock as the number set forth next to such Underwriter's name in the preceding
table bears to the total number of shares of Common Stock set forth next to
the names of all of the U.S. Underwriters in the preceding table.
 
  The Company has applied to list the Common Stock on the NYSE, subject to
official notice of issuance, under the symbol "CGT".
   
  At the request of the Company, the Underwriters have reserved for sale, at
the initial public offering price; a number of shares equal to 5% of total
number of shares being offered in the Common Stock Offering for directors,
officers, employees, business associates and related persons of the Company.
The number of shares of Common Stock available for sale to the general public
will be reduced to the extent such individuals purchase such reserved shares.
Any reserved shares which are not so purchased will be offered by the
Underwriters to the general public on the same basis as the other shares
offered hereby.     
 
  Each of the Company, the Selling Stockholders, the directors and executive
officers of the Company has agreed that, without the prior written consent of
Morgan Stanley & Co. Incorporated on behalf of the Underwriters, it will not,
during the period ending 180 days after the date of this Prospectus, (i)
offer, pledge, sell, contract to sell, sell any option or contract to
purchase, purchase any option or contract to sell, grant any option, right or
warrant to purchase, lend or otherwise transfer, or dispose of, directly or
indirectly, any shares of Common Stock or any securities convertible into or
exercisable or exchangeable for Common Stock or (ii) enter into any swap or
other arrangement that transfers to another, in whole or in part, any of the
economic consequences of ownership of the Common Stock, whether any such
transaction described in clause (i) or (ii) above is to be settled by delivery
of Common Stock or such other securities, in cash or otherwise. The
restrictions described in this paragraph do not apply to (x) the sale to the
Underwriters of the shares of Common Stock offered hereby, (y) the issuance by
the Company of shares of Common Stock upon the exercise of any options granted
or shares of Common Stock issued pursuant to existing benefit plans of the
Company or (z) transactions of any person other than the Company relating to
shares of Common Stock or other securities acquired in open market
transactions after the completion of the Offering.
 
  The Underwriters have informed the Company that they do not intend sales to
discretionary accounts to exceed five percent of the total number of shares of
Common Stock offered by them.
 
  In order to facilitate the offering of the Common Stock, the Underwriters
may engage in transactions that stabilize, maintain or otherwise affect the
price of the Common Stock. Specifically, the Underwriters may overallot in
connection with the offering, creating a short position in the Common Stock
for their own account. In addition, to cover overallotments or to stabilize
the price of the Common stock, the Underwriters may bid for, and purchase,
shares of Common Stock in the open market. Finally, the underwriting syndicate
may reclaim selling concessions allowed to an Underwriter or a dealer for
distributing the Common Stock in the Common Stock Offering, if the syndicate
repurchases previously distributed Common Stock in transactions to cover
 
                                      110
<PAGE>
 
syndicate short positions, in stabilization transactions or otherwise. Any of
these activities may stabilize or maintain the market price of the Common
Stock above independent market levels. The Underwriters are not required to
engage in these activities and may end any of these activities at any time.
   
  From time to time, Morgan Stanley & Co. Incorporated has provided and
continues to provide investment banking services to the Company. In addition,
in conjunction with the Formation Transactions and immediately prior to the
closing of the Common Stock Offering, Morgan Stanley & Co. Incorporated will
loan $291.0 million to Linden Ltd. pursuant to the Bridge Loan. The Company
expects that it will advance as a loan to Linden Ltd. a portion of the
proceeds of the Debt Offering necessary for Linden Ltd. to repay the Bridge
Loan in full. See "Capitalization". In addition, to facilitate the
consummation of the Formation Transactions, Morgan Stanley & Co. Incorporated
will loan an aggregate of $83.9 million to the McNair Interests and the
Minority Interests which will be repaid with a portion of the proceeds of the
Common Stock Offering.     
 
  The Company, the Selling Stockholders and the Underwriters have agreed to
indemnify each other against certain liabilities, including liabilities under
the Securities Act.
 
PRICING OF OFFERING
 
  Prior to the Offering, there has been no public market for the Common Stock.
The initial public offering price will be determined by negotiations between
the Company and the Representative. Among the factors to be considered in
determining the initial public offering price will be the future prospects of
the Company and its industry in general, revenues, earnings and certain other
financial and operating information of the Company in recent periods, and the
price-earnings ratios, price-sales ratios, market prices of securities and
certain financial and operating information of companies engaged in activities
similar to those of the Company. The estimated initial public offering price
range set forth on the cover page of this Prospectus is subject to change as
the result of market conditions and other factors.
 
             CERTAIN UNITED STATES FEDERAL INCOME TAX CONSEQUENCES
 
  The following is a summary of certain material United States federal income
tax considerations relating to the purchase, ownership and disposition of
Common Stock to U.S. Holders (as defined below) and certain material United
States federal income and estate tax consequences relating to the purchase,
ownership and disposition of Common Stock to non-U.S. Holders (as defined
below). This summary is based on current provisions of the United States
Internal Revenue Code of 1986, as amended (the "Code"), existing, temporary
and proposed regulations promulgated thereunder and administrative and
judicial interpretations thereof, all of which are subject to change, possibly
with retroactive effect.
 
  This summary deals only with initial purchasers of Common Stock who hold
Common Stock as capital assets and does not address tax considerations
applicable to investors that may be subject to special tax rules, including,
without limitation, banks, insurance companies, tax-exempt entities, regulated
investment companies, common trust funds, dealers in securities, or persons
that hold Common Stock as part of a hedge, conversion or constructive sale
transaction, straddle or other risk reduction transaction. This discussion
also does not address the tax consequences arising under the laws of any
foreign, state or local jurisdiction.
 
  INVESTORS CONSIDERING THE PURCHASE OF COMMON STOCK SHOULD CONSULT THEIR OWN
TAX ADVISORS AS TO THE PARTICULAR TAX CONSEQUENCES TO THEM OF ACQUIRING,
HOLDING OR OTHERWISE DISPOSING OF COMMON STOCK, INCLUDING THE EFFECT AND
APPLICABILITY OF STATE, LOCAL OR FOREIGN TAX LAWS.
 
U.S. HOLDERS
 
  As used herein, the term "U.S. Holder" means a holder of Common Stock that
is (i) a citizen or resident of the United States, (ii) a corporation,
partnership or other entity created or organized in or under the laws of the
 
                                      111
<PAGE>
 
United States or any political subdivision thereof, (iii) an estate, the
income of which is subject to United States federal income taxation regardless
of its source, or (iv) a trust, the administration of which is subject to the
primary supervision of a court within the United States and which has one or
more United States persons with authority to control all substantial
decisions. As used herein, the term "non-U.S. Holder" means a holder of Common
Stock other than a U.S. Holder.
 
  Dividends. Distributions, if any, made with respect to Common Stock
generally will be includible in the income of a U.S. Holder as ordinary
dividend income to the extent of the Company's current or accumulated earnings
and profits as determined for U.S. federal income tax purposes. If the amount
distributed to the holder of shares of Common Stock exceeds the Common
Stockholders' share of the current and accumulated earnings and profits of the
Company, the excess will be treated first as a non-taxable return of capital
to the extent of such U.S. Holder's adjusted basis in the Common Stock and,
thereafter, as a gain from the sale or exchange of a capital asset. Any such
excess would not be eligible for the dividends-received deduction generally
available with respect to dividends paid to corporate holders of the Common
Stock. During the initial years of the Company's operations, the Company
expects that dividends distributed with respect to the Common Stock will
exceed the Company's current and accumulated earnings and profits. No
assurance can be given, however, that distributions made with respect to the
Common Stock will exceed the Company's current and accumulated earnings and
profits nor, if such distributions are made, regarding the amount of any such
excess. Furthermore, although the Company has taken certain steps in order to
"step up" its basis in the assets of Linden Venture, Camden Cogen and Selkirk
Venture, with the result that the Company expects certain depreciation
deductions and reductions to earnings and profits to be available to it, such
deductions and reductions depend, in part, on the Company's determination of
the relative value of the respective assets of each of Linden Venture and
Camden Cogen. Such valuations are not binding upon the United States Internal
Revenue Service ("IRS"). If the IRS were to successfully challenge such
valuations, it is likely that at least a portion of such depreciation
deductions and reductions in earnings and profits for the years challenged
would be reduced or moved to later periods, possibly resulting in a larger
portion of the distributions with respect to the Common Stock made in such
years being taxable as a dividend.
 
  Sale or Other Disposition of Common Stock. Upon the sale or exchange of
Common Stock, U.S. Holders generally will recognize capital gain or capital
loss equal to the difference between the amount realized on such sale or
exchange and the U.S. Holder's adjusted basis in such shares.
 
NON-U.S. HOLDERS
 
  Dividends. Distributions with respect to Common Stock paid by the Company
out of current and accumulated earnings and profits, as determined for United
States federal income tax purposes, to a non-U.S. Holder generally will be
subject to withholding of United States federal income tax at the rate of 30%,
unless reduced or eliminated by an applicable tax treaty or unless such
dividends are treated as effectively connected with a United States trade or
business of the non-U.S. Holder. Distributions paid by the Company in excess
of its current and accumulated earnings and profits will be treated first as a
nontaxable return of capital to the extent of the non-U.S. Holder's adjusted
basis in his Common Stock and, thereafter, as gain from the sale or exchange
of a capital asset. Under current law, if the Company cannot determine at the
time it makes a distribution whether such distribution will exceed the current
and accumulated earnings and profits of the Company, the gross amount of the
distribution will be subject to withholding at the same rate as dividends.
Amounts so withheld, however, will be refundable or creditable against the
non-U.S. Holder's United States federal income tax liability if it is
subsequently determined that such distribution was, in fact, in excess of the
current and accumulated earnings and profits of the Company. Treasury
Regulations effective for payments made after December 31, 2000 (the "New
Regulations"), would permit the Company to elect to reduce the amount of
withholding with respect to a distribution if, based on a reasonable estimate
of the Company's anticipated accumulated and current earnings and profits for
the taxable year in which such distribution is made, such distribution would
be in excess of such earnings and profits. No assurance can be given, however,
that the Company will be eligible to make this election with respect to any
distribution, or if eligible, that the Company will make such election.
 
 
                                      112
<PAGE>
 
  If the receipt of a dividend is treated as being effectively connected with
the conduct of a United States trade or business by a non-U.S. Holder, the
dividend received by such non-U.S. Holder will be subject to United States
federal income tax in the same manner as U.S. Holders generally (and, in the
case of a corporate holder, possibly an additional branch profits tax).
Effectively connected dividends may be subject to different treatment under an
applicable tax treaty depending on whether such dividends are attributable to
a permanent establishment of the non-U.S. Holder in the United States.
 
  Currently, for purposes of determining whether tax is to be withheld at the
30% rate or at a reduced rate as specified in an applicable income tax treaty,
the Company will ordinarily presume that dividends paid to an address in a
foreign country are paid to a resident of such country absent knowledge that
such presumption is not warranted. Under the New Regulations, non-U.S. Holders
will be required to satisfy certain applicable certification requirements to
claim treaty benefits.
 
  Sale or Other Disposition of Common Stock. A non-U.S. Holder generally will
not be subject to United States federal income tax in respect of any gain
recognized on the sale or other taxable disposition of Common Stock unless (i)
the gain is effectively connected with a trade or business of the non-U.S.
Holder in the United States; (ii) in the case of a non-U.S. Holder who is an
individual and holds Common Stock as a capital asset, the holder is present in
the United States for 183 or more days in the taxable year of the disposition
and either (a) the individual has a "tax home" for United States federal
income tax purposes in the United States or (b) the gain is attributable to an
office or other fixed place of business maintained by the individual in the
United States; (iii) the non-U.S. Holder is subject to tax pursuant to the
provisions of United States federal income tax law applicable to certain
United States expatriates; or (iv) (A) the Company is or has been during
certain periods preceding the disposition a "U.S. real property holding
corporation" for United States federal income tax purposes and (B) provided
that the Common Stock continues to be "regularly traded on an established
securities market" for United States federal income tax purposes, the non-U.S.
Holder held, directly or indirectly, at any time during the five-year period
ending on the date of disposition, more than 5% of the outstanding Common
Stock. Non-U.S. Holders who would be subject to United States federal income
tax with respect to gain recognized on a sale or other disposition of Common
Stock should consult applicable treaties, which may provide for different
rules.
 
  Backup Withholding and Information Reporting. Payments of dividends to a
non-U.S. Holder at an address outside the United States may be subject to
information reporting, but will not, under current law, generally be subject
to backup withholding. The payment of the proceeds of the disposition of
Common Stock to or through the United States office of a broker is subject to
information reporting and backup withholding at a rate of 31% unless the owner
of the stock certifies its non-United States status under penalties of perjury
or otherwise establishes an exemption. The payment of the proceeds of the
disposition by a non-U.S. Holder of Common Stock to or through a foreign
office of a broker will not be subject to backup withholding. The Service has
indicated, however, that it is studying the possible application of backup
withholding in the case of a foreign office of a broker that is (a) a United
States person, (b) a United States-controlled foreign corporation or (c) a
foreign person 50% or more of whose gross income for certain periods is from a
United States trade or business. Moreover, in the case of foreign offices of
such brokers, information reporting will apply to such payments of proceeds
unless such broker has documentary evidence in its files of the owner's
foreign status and has no actual knowledge to the contrary. Backup withholding
is not an additional tax. Amounts withheld under the backup withholding rules
are generally allowable as a refund or credit against such non-U.S. Holder's
United States federal income tax liability, if any, provided that the required
information is furnished to the IRS.
 
  Federal Estate Taxes. Common Stock owned or treated as owned by an
individual who is not a citizen or resident (as specifically defined for
United States federal estate tax purposes) of the United States at the time of
such individual's death will be included in such individual's gross estate for
United States federal income tax purposes, unless an applicable estate tax
treaty provides otherwise.

  "tracking account" means an accounting device designed to relate a utility
power purchaser's Avoided Cost to the payments it makes on such power purchase
agreement over the life thereof. Often, because of project financing
considerations, payments exceed the initial estimated Avoided Cost in the
early years of a power purchase agreement and come into line with, and are
less than, such estimated Avoided Costs in later years of the agreement.
Accordingly, many power purchase agreements set up the device of a tracking
account so that if there is a termination of the power purchase agreement at a
time when the utility purchaser has paid amounts exceeding its estimated
Avoided Costs, the utility can be paid back the difference. To the extent that
the amounts paid by the purchaser exceed its estimated Avoided Cost, the
venture selling the power under the power purchase agreement is indebted to
the purchaser for such amount, which is recorded in the tracking account.

                            NOTES TO BALANCE SHEET
 
(1) ORGANIZATION AND BASIS OF PRESENTATION
 
  Cogen Technologies, Inc. (the "Company") was incorporated in May 1998 to
acquire control of certain entities and interests owned by Robert C. McNair
and members of his family and by entities controlled by his family (the
"McNair Interests") and by other persons or entities with no relation to the
McNair Interests (the "Minority Interests"). In connection with the
organization of the Company, the McNair Interests and the Minority Interests
contributed an aggregate amount of $1,000 to the Company for 820 shares and
180 shares, respectively, of the Company's common stock.
 
(2) INFORMATION (UNAUDITED) AVAILABLE SUBSEQUENT TO THE DATE OF THE
INDEPENDENT AUDITORS' REPORT
   
  Through the following series of transactions (the "Formation Transactions"),
the Company intends to acquire certain interests from the McNair Interests and
the Minority Interests (dollar and share amounts are based on a Common Stock
Offering (as defined herein) price of $15.00 per share):     
     
    (i) The Company will issue 28.7 million shares of common stock with an
  estimated market value of $429.7 million in exchange for 49.9% of the
  general and limited partnership interests in Cogen Technologies Linden Ltd.
  ("Linden Ltd."), a Texas limited partnership which is the managing general
  partner of Cogen Technologies Linden Venture, LP ("Linden Venture"), a
  Delaware limited partnership that owns and operates a 715-megawatt
  cogeneration facility in Linden, New Jersey;     
     
    (ii) The Company will issue 9.9 million shares of common stock with an
  estimated market value of $147.9 million plus $1.0 million in cash in
  exchange for 100% of the outstanding common stock of Cogen Technologies
  Camden, Inc. ("Camden Inc.") and the limited partnership interests in Cogen
  Technologies Camden GP Limited Partnership ("Camden GPLP") held by the
  Minority Interests. Camden Inc. is a Texas corporation that is the general
  partner of Camden GPLP, a Delaware partnership that is the managing general
  partner of Camden Cogen LP ("Camden Cogen"), a Delaware partnership that
  owns and operates a 146-megawatt cogeneration facility in Camden, New
  Jersey;     
     
    (iii) McNair Energy Services Corporation ("MESC"), a Texas corporation
  owned approximately 82% by the McNair Interests and 18% by the Minority
  Interests, will be merged with Cogen Technologies Bayonne, Inc., a wholly
  owned subsidiary of the Company, pursuant to which merger Cogen
  Technologies Bayonne, Inc. will survive and the shareholders of MESC will
  receive 14.4 million shares of the Company's common stock with an estimated
  market value of $217.4 million. MESC's wholly owned subsidiary Cogen
  Technologies NJ, Inc. ("NJ Inc.") is the managing general partner of Cogen
  Technologies NJ Venture ("NJ Venture"), a New Jersey general partnership
  that owns and operates a 176-megawatt cogeneration facility in Bayonne, New
  Jersey.     
     
    (iv) The Company will issue 1.7 million shares of common stock with an
  estimated market value of $25.2 million in exchange for 100% of the limited
  and general partnership interests in Cogen Technologies Selkirk, L.P.
  ("Selkirk LP"). All of such interests are held by the McNair Interests and
  the Minority Interests. Selkirk LP holds a 78% limited partnership interest
  in Selkirk Cogen Partners, L.P. ("Selkirk Cogen") which owns and operates a
  345-megawatt cogeneration facility in Bethlehem, New York;     
     
    (v) The Company will issue 0.3 million shares of common stock with an
  estimated market value of $4.8 million in exchange for 100% of the common
  stock of CT Global Insurance, Ltd. ("CT Global"), a Bermuda corporation
  whose primary business is underwriting a portion of the insurance carried
  by NJ Venture, Camden Cogen and Linden Venture.     
     
    (vi) Linden Ltd. will borrow $291.0 million under the terms of a loan
  agreement with Morgan Stanley & Co. Incorporated (the "Bridge Loan") and
  redeem its remaining general and limited partnership interests     
 
                                      F-5
<PAGE>
 
                           COGEN TECHNOLOGIES, INC.
 
                      NOTES TO BALANCE SHEET--(CONTINUED)
     
  in consideration for the distribution of a $140.4 million account
  receivable and a $291.0 million in cash. The Bridge Loan will be evidenced
  by a subordinated promissory note in favor of Morgan Stanley, which note
  will bear interest at the rate of 24% per annum. Immediately following the
  issuance of the Senior Notes (as discussed hereinafter), the Company will
  loan $291.0 million of the proceeds to Linden Ltd. for repayment of the
  Bridge Loan.     
   
  The Camden Inc. and Linden Ltd. transactions are structured in a manner so
as not to qualify for tax-free incorporation or tax-free reorganization
treatment for the McNair Interests and the Minority Interests, thereby
providing the Company with a step-up in tax basis to fair market value. The
inclusion in the Camden Inc. transaction of the $1.0 million in cash is
necessary to achieve such treatment. No cash consideration is necessary with
respect to the Linden Ltd. partnership interests.     
   
  Prior to the Formation Transactions, the ownership interests of the McNair
Interests and the Minority Interests in Linden Ltd., Camden Inc. and the
limited partnership interests in Camden GPLP, approximately 89.5% of MESC and
CT Global are identical. Following the Formation Transactions with respect to
such entities the ownership interests of the McNair Interests and the Minority
Interests in the Company will be identical to their prior interests in the
entities acquired. Accordingly, the Company's acquisition of Linden Ltd.,
Camden Inc. and the limited partnership interests in Camden GPLP,
approximately 89.5% of MESC and CT Global will be accounted for at historical
cost as a reorganization of entities under common control.     
   
  The acquisition of the 81.7% of the partnership interests in Selkirk LP held
by the McNair Interests will be accounted for at historical cost as a
reorganization of entities under common control. The acquisition of the 18.3%
of the partnership interests in Selkirk LP held by the Minority Interests and
the 10.5% of MESC for which the ownership of a portion of the Minority
Interests is not identical to that of the other entities, will be accounted
for as purchase transactions. The purchase price for the Selkirk LP interests
held by the Minority Interests and the 10.5% interest in MESC is $4.5 million
and $22.5 million, respectively.     
   
  The accounts of Linden Ltd., Camden Inc., MESC, Selkirk LP and CT Global
will be included in the Company's consolidated financial statements. The
Company's investments in Linden Venture, Camden Cogen, NJ Venture and Selkirk
Cogen will be accounted for using the equity method.     
          
  Because the ownership interests are not identical among each of (i) MESC,
(ii) Selkirk LP and (iii) the aggregate of Linden Ltd., Camden Inc., the
limited partnership interests in Camden GPLP and CT Global, the valuation of
the interests acquired by the Company with respect to each of these three
groups was agreed to in arms-length negotiations. The allocation of the
aggregate valuation among Linden Ltd., Camden Inc., the limited partnership
interests in Camden GPLP and CT Global for purposes of determining their new
tax bases and the amounts necessary to redeem 50.1% of the general and limited
partnership interests in Linden Ltd. is based upon their relative fair market
values.     
   
  Following the Formation Transactions, the Company will hold, directly or
indirectly, 100% of the general and limited partnership interests of Camden
GPLP, Linden Ltd. and Selkirk LP and 100% of the common stock of NJ Inc. The
Company's interest in the earnings and cash distributions of NJ Venture,
Camden Cogen, Linden Venture and Selkirk Cogen is as follows:     
     
    (i) Under the terms of NJ Venture's joint venture agreement, NJ Inc. is
  allocated 86.5% of NJ Venture's profits and losses and receives 86.5% of
  all cash distributions.     
     
    (ii) Under the terms of Camden Cogen's partnership agreement, monthly
  cash distributions are allocated 1% to Camden GPLP and 99% to the limited
  partner up to a specified cumulative rate of return (approximately $0.3
  million to $0.4 million per month through May 2007 and varying amounts
  thereafter)

                      NOTES TO BALANCE SHEET--(CONTINUED)
     
  and the remaining available cash for the month is allocated 99% to Camden
  GPLP and 1% to the limited partner. Once the limited partner has received
  its specified rate of return, cash distributions will be allocated 90% to
  Camden GPLP and 10% to the limited partner. During 1997, 1996 and 1995
  Camden GPLP received 74%, 83% and 84%, respectively, of Camden Cogen's cash
  distributions. Camden Cogen's income before depreciation is allocated as
  follows: (a) an amount equal to debt principal payments, 100% to the
  limited partner; (b) an amount equal to and allocated on the same basis as
  cash distributed; and (c) any remainder generally 99% to Camden GPLP and 1%
  to the limited partner. Losses are allocated 100% to Camden GPLP until its
  capital account equals zero and then to the limited partner until its
  capital account equals zero and then to Camden GPLP. Depreciation is
  allocated 100% to the limited partner until its capital account equals zero
  and then to Camden GPLP. During 1997, 1996 and 1995 Camden GPLP was
  allocated 91%, 94% and 97%, respectively, of Camden Cogen's net income.
         
    (iii) Under the terms of Linden Venture's partnership agreement, cash is
  distributed monthly, 1% to Linden Ltd. and 99% to the limited partner up to
  a specified rate of return (approximately $4.3 million per month through
  September 1998, approximately $3.0 million per month from October 1998
  through September 2001 and between $4.3 million and $4.8 million per month
  thereafter) ("Tranche 1"), then 99% to Linden Ltd. and 1% to the limited
  partner up to a capped amount, which is twice the amount of Tranche 1, and
  the remainder 90% to Linden Ltd. and 10% to the limited partner. During
  1997, 1996 and 1995 Linden Ltd. received 59%, 60% and 54%, respectively, of
  Linden Venture's cash distributions. Linden Venture's income before
  depreciation is allocated to the partners on the basis of cash distributed
  with any excess primarily allocated 99% to Linden Ltd. Losses are allocated
  100% to Linden Ltd. until its capital account equals zero and then to the
  limited partner until its capital account equals zero with any remainder
  allocated 100% to Linden Ltd. Depreciation up to $525.0 million is
  allocated 5% to Linden Ltd. and 95% to the limited partners. All remaining
  depreciation is allocated 99% to Linden Ltd. During 1997, 1996 and 1995
  Linden Ltd. was allocated 70%, 71% and 66%, respectively, of Linden
  Venture's net income.     
     
    (iv) Under the terms of Selkirk Cogen's amended partnership agreement,
  available cash is distributed, up to a specified level (the "Level 1
  Distributions"), 99% to the partners in accordance with their current
  equity interests and 1% in accordance with the original ownership structure
  (which does not include Selkirk LP). Any additional funds are distributed
  99% in accordance with the original ownership structure and 1% to the
  partners in accordance with their current equity interests. Subsequent to
  the earlier of September 1, 2013 or the date all Level 1 Distributions are
  made, distributions will be made based on the partners' residual interest
  (17.3% for the interest of Selkirk LP). Under the terms of the amended
  partnership agreement, Selkirk LP is being allocated a total of
  approximately 6% of the earnings of Selkirk Cogen.     
 
  Following the Formation Transactions, the McNair Interests and the Minority
Interests intend to sell shares of the Company's common stock in a public
offering (the "Common Stock Offering"). The Company will issue no shares and
will receive no proceeds from the Common Stock Offering. In connection with
the Common Stock Offering, the Company will pay certain costs which are
estimated to total $1.8 million.
 
  Following the Formation Transactions, the Company intends to issue $400.0
million of Senior Notes, the proceeds from which will be used to loan an
amount to Linden Ltd. for repayment of the Bridge Loan, to retire amounts
payable to affiliates, to pay certain expenses related to the Formation
Transactions, the Common Stock Offering and the issuance of the Senior Notes
and for working capital purposes. The Senior Notes mature $100.0 million in
2005, $150.0 million in 2010 and $150.0 million in 2018 and are expected to
bear interest at approximately 6.72%, 6.89% and 7.33% per annum, respectively.
The Senior Notes have no sinking fund requirements and no principal payments
are required prior to maturity.
 
  The Senior Notes will be secured, on an equal basis with the senior secured
bank indebtedness, by a security interest granted by the Company on certain
direct wholly-owned subsidiaries of the Company, which subsidiaries
 
                                      F-7
<PAGE>
 
                           COGEN TECHNOLOGIES, INC.
 
                      NOTES TO BALANCE SHEET--(CONTINUED)
 
own all of the Company's equity interests in the ventures. The Indenture to be
executed in conjunction with the Debt Offering will contain certain covenants,
including restrictive covenants that (i) limit indebtedness of the Company,
other than the Senior Notes, up to $300.0 million at any one time outstanding
in senior secured bank indebtedness, certain other parity indebtedness the
issuance of which either is incurred in compliance with a coverage ratio
requirement or will not result in a rating downgrade of the Senior Notes and
subordinated indebtedness, (ii) limit additional indebtedness of the ventures
(except Selkirk Venture) in which the Company currently has an interest, other
than up to $100.0 million at any one time outstanding for plant improvements
and expansion and amounts required to satisfy any fiduciary responsibilities
of the partners or venturers of each of the ventures, and (iii) prohibit
distributions to stockholders and on account of subordinated indebtedness owed
to affiliates unless no default exists under the Indenture and such
distributions do not exceed 100% of Funds From Operations (as of the closing
date of the issuance of the Senior Notes) plus $50.0 million. The Indenture
will further contain provisions that upon achieving a prescribed level of
diversification of interests owned by the Company in at least eight power
project ventures, the foregoing security interests, mandatory redemption
provisions and covenants and, subject to a further condition, security
interest, and certain events of default, will be permanently terminated. The
closings of each of the Common Stock Offering and the Debt Offering are
conditioned upon the consummation of the other.
 
  Because the operations of the Company following the Formation Transactions
will be conducted primarily by its subsidiaries and ultimately by the ventures
in which the subsidiaries have interests, the Company's cash flow and its
ability to service indebtedness, including its ability to pay the interest on
and principal of its indebtedness and to pay dividends on the Common Stock,
will depend entirely upon the earnings of the ventures and the subsidiaries
and the distribution of those earnings to the Company. The Company initially
will have no significant business other than its ownership interests in the
subsidiaries and its planned development and acquisition business. The future
earnings of the ventures will be affected by a number of factors, including
competition in the power generation industry, possible changes in existing
laws and regulations, possible amendment or termination of the ventures' above
market power purchase agreements and various other economic, regulatory and
operating factors.
       
  Certain executive officers of the Company will also serve as directors or
executive officers, or both, of certain other entities controlled by Mr.
McNair. In addition, the Company expects to provide certain management,
financial and administrative support services to such other entities
controlled by Mr. McNair. For such services the Company will receive a fee
equal to the Company's estimated cost plus an appropriate markup. The
Company's estimated cost, including office space and facilities, will be
determined on a full allocation basis, including employee salaries and
benefits and direct charges.

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To Cogen Technologies Group:
 
  We have audited the accompanying combined balance sheets of Cogen
Technologies Group (a group of cogeneration investing entities owned by Robert
C. McNair and affiliates) as of December 31, 1997 and 1996, and the related
combined statements of income, owners' equity and cash flows for each of the
three years in the period ended December 31, 1997. These financial statements
are the responsibility of the Group's management. Our responsibility is to
express an opinion on these financial statements based on our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Cogen Technologies Group
as of December 31, 1997 and 1996, and the results of their operations and
their cash flows for each of the three years in the period ended December 31,
1997, in conformity with generally accepted accounting principles.

                           COGEN TECHNOLOGIES GROUP
 
                    NOTES TO COMBINED FINANCIAL STATEMENTS
 
(1) ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
 Organization and Nature of Operations
   
  The combined financial statements of the Cogen Technologies Group (the
"Group") includes McNair Energy Services Corp. ("MESC") and its wholly owned
subsidiary Cogen Technologies NJ, Inc. ("NJ Inc."), Cogen Technologies Camden,
Inc. ("Camden Inc."), Cogen Technologies Linden, Ltd. ("Linden Ltd."), Cogen
Technologies Selkirk LP ("Selkirk LP"), CT Global Insurance, Ltd. ("CT
Global") and the limited partnership interests in Cogen Technologies Camden GP
Limited Partnership ("Camden GPLP") not held by Camden Inc. The financial
statements of the Group are presented on a combined basis since all such
entities were under the common control and management of the McNair Interests
for all periods presented. All material transactions between the combined
entities have been eliminated.     
 
  MESC is a Texas corporation that is owned approximately 82% by Robert C.
McNair, members of his immediate family and related trusts (the "McNair
Interests") and owns 100% of NJ Inc., a Delaware corporation. NJ Inc. provides
planning, operational and financial management services as managing general
partner for Cogen Technologies NJ Venture ("NJ Venture"), a New Jersey general
partnership that owns and operates a 176-megawatt cogeneration facility in
Bayonne, New Jersey. The allocation of NJ Venture's earnings and cash
distributions to NJ Inc. is discussed in Note 2.
 
  Camden Inc. is a Texas corporation that is owned 100% by the McNair
Interests and is the general partner of Camden GPLP, a Delaware limited
partnership. Under the terms of Camden GPLP's partnership agreement, Camden
Inc. is allocated 82% of Camden GPLP's profits and losses and receives 82% of
all cash distributions. Camden GPLP provides planning, operational and
financial management services as managing general partner of Camden Cogen LP
("Camden Cogen"), a Delaware limited partnership that owns and operates a 146-
megawatt cogeneration facility in Camden, New Jersey. The allocation of Camden
Cogen's earnings and cash distributions to Camden GPLP is discussed in Note 2.
 
  Linden Ltd. is a Texas limited partnership whose general partner, Cogen
Technologies, Inc. ("Cogen"), is owned 100% by the McNair Interests. Under the
terms of Linden Ltd.'s partnership agreement, Cogen is allocated 82% of Linden
Ltd.'s profits and losses and receives 82% of all cash distributions. Linden
Ltd. provides planning, operational and financial management services as
managing general partner of Cogen Technologies Linden Venture, LP ("Linden
Venture"), a Delaware limited partnership that owns and operates a 715-
megawatt cogeneration facility in Linden, New Jersey. The allocation of Linden
Venture's income and cash distributions to Linden Ltd. is discussed in Note 2.
   
  Selkirk LP is a Delaware limited partnership in which the McNair Interests
hold a 1% general partner interest and an approximate 81% limited partner
interest. Selkirk LP holds a 78% limited partnership interest in Selkirk Cogen
Partners, L.P. ("Selkirk Cogen"), a Delaware limited partnership which owns
and operates a 345-megawatt cogeneration facility in Bethlehem, New York. The
allocation of Selkirk Cogen's income and cash distributions to Selkirk LP is
discussed in Note 2.     
   
  The Group's investments in NJ Venture, Camden Cogen and Linden Venture are
accounted for using the equity method of accounting since the limited partners
have substantive participating rights with respect to the partnerships'
operations. The Group's investment in Selkirk Cogen is accounted for using the
equity method of accounting because the Company holds only limited partnership
interests and the operations of the partnership are under the control of the
managing general partner.     
 
  CT Global is a Bermuda corporation owned approximately 82% by the McNair
Interests whose primary business is underwriting a portion of the insurance
carried by NJ Venture, Camden Cogen and Linden Venture.

                           COGEN TECHNOLOGIES GROUP
 
              NOTES TO COMBINED FINANCIAL STATEMENTS--(CONTINUED)
 
 Cash and Cash Equivalents/Restricted Cash
 
  All highly liquid short-term investments with original maturities of three
months or less are considered to be cash equivalents. At December 31, 1997 and
1996, most of the Group's cash was held by Linden Ltd. and all such cash was
restricted either to service Linden Ltd.'s debt or, if necessary, to make
working capital loans to Linden Venture.
 
 Credit Risk
 
  Financial instruments which potentially subject the Group to credit risk
consist primarily of cash and accounts receivable. Cash accounts are held by
major financial institutions and accounts receivable are with related parties.
 
 Income Taxes
   
  Federal and state income taxes with respect to Camden GPLP, Linden Ltd. and
Selkirk LP and federal income taxes with respect to Camden Inc. are not levied
at the partnership or corporate levels but rather on the individual partners
or shareholders. Accordingly, such income taxes have not been recognized in
the combined financial statements for such entities. MESC and CT Global
account for federal income taxes and MESC and Camden Inc. account for state
income taxes in accordance with Statement of Accounting Standards ("SFAS") No.
109, "Accounting for Income Taxes". Deferred tax assets and liabilities are
recognized based on anticipated future tax consequences attributable to
differences between the financial statement carrying amounts of assets and
liabilities and their respective tax bases.     
 
  Following the Formation Transactions discussed in Note 9, Cogen
Technologies, Inc. will be the partner or shareholder of the entities which
comprise the Group, and federal and state income taxes will be recognized in
its consolidated financial statements. Pro Forma income taxes have been
presented in the Group's combined Statement of Income to reflect income taxes
assuming the Group were a taxable entity.
 
 Use of Estimates
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires the use of certain estimates and
assumptions that affect the reported amounts of assets and liabilities and the
disclosure of contingent assets and liabilities, if any, and the periods in
which certain items of revenue and expense are included. Actual results may
differ from such estimates.
 
 Earnings Per Share
 
  Historical earnings per share have been omitted from the combined statements
of income since such information is not meaningful and the historically

(1) Through December 31, 1997 NJ Inc., received distributions from NJ Venture
    in excess of its proportionate share of NJ Ventures earnings of $13.0
    million ($12.7 million at December 31, 1996, $6.6 million at December 31,
    1995 and $3.3 million at December 31, 1994). All partners share in
    liquidation rights to the extent of their individual capital accounts,
    accordingly, such excess is classified as a long-term liability in the
    financial statements. The amount reflected as Investment in NJ Venture
    represents NJ Inc.'s unamortized cost in excess of its equity in the
    underlying net assets of NJ Venture and such amount is being amortized
    over twenty years.

  Under the terms of NJ Venture's joint venture agreement, NJ Inc. is
allocated 86.5% of NJ Venture's profits and losses and receives 86.5% of all
cash distributions.
 
  Under the terms of Camden Cogen's partnership agreement, monthly cash
distributions are allocated 1% to Camden GPLP and 99% to the limited partner
up to a specified cumulative rate of return (approximately $0.3 million to
$0.4 million per month through May 2007 and varying amounts thereafter) and
the remaining available cash for the month is allocated 99% to Camden GPLP and
1% to the limited partner. Once the limited partner has received its specified
rate of return, cash distributions will be allocated 90% to Camden GPLP and
10% to the limited partner. During 1997, 1996 and 1995 Camden GPLP received
74%, 83% and 84%, respectively, of Camden Cogen's cash distributions. Camden
Cogen's income before depreciation is allocated as follows: (i) an amount
equal to debt principal payments, 100% to the limited partner; (ii) an amount
equal to and allocated on the same basis as cash distributed; and (iii) any
remainder generally 99% to Camden GPLP and 1% to the limited partner. Losses
are allocated 100% to Camden GPLP until its capital account equals zero and
then to the limited partner until its capital account equals zero and then to
Camden GPLP. Depreciation is allocated 100% to the limited partner until its

September 2001 and between $4.3 million and $4.8 million per month thereafter)
("Tranche 1"), then 99% to Linden Ltd. and 1% to the limited partner up to a
capped amount, which is twice the amount of Tranche 1, and the remainder 90%
to Linden Ltd. and 10% to the limited partner. During 1997, 1996 and 1995
Linden Ltd. received 59%, 60% and 54%, respectively, of Linden Venture's cash
distributions. Linden Venture's income before depreciation is allocated to the
partners on the basis of cash distributed with any excess primarily allocated
99% to Linden Ltd. Losses are allocated 100% to Linden Ltd. until its capital
account equals zero and then to the limited partner until its capital account
equals zero with any remainder allocated 100% to Linden Ltd. Depreciation up
to $525.0 million is allocated 5% to Linden Ltd. and 95% to the limited

original ownership structure and 1% to the partners in accordance with their
current equity interests. Subsequent to the earlier of September 1, 2013 or
the date all Level 1 Distributions are made, distributions will be made based
on the partners' residual interest (17.3% for the

services to Linden Venture for a monthly management fee equal to 1.5% of
Linden Venture's gross revenues. Such fees charged to Linden Venture in 1997,
1996 and 1995 totaled $4.6 million, $4.5 million and $3.9 million,
respectively. RCM Management Services, L.P. ("Management Services"), which is
controlled by the McNair Interests, provides planning, operational and
financial management services to Camden GPLP and Linden Ltd. for monthly fees
equal to 1.5% of the gross revenues of Camden Cogen and Linden Venture,
respectively, and to Selkirk LP for monthly fees equal to 1.5% of 48.6% of the
gross revenues of Selkirk Cogen. Such fees charged were as follows in 1997,
1996 and 1995: (i) Camden GPLP--$1.2 million, $1.2 million and $1.0 million,
respectively; and (ii) Linden Ltd.--$4.6 million, $4.5 million and $3.9
million, respectively; and (iii) Selkirk LP--$1.2 million, $1.1 million and
$1.0 million, respectively.     
   
  Under the terms of an agreement between Management Services and NJ Inc.,
Management Services provides planning, operational and financial management
services directly to NJ Venture for a monthly management fee equal to 1.5% of
NJ Venture's gross revenues. Such fees charged to NJ Venture totaled $1.4
million in each of 1997, 1996 and 1995. Under the terms of such agreement NJ
Venture has assumed the cost and pays such fee directly to Management
Services.     
   
  Cogen Technologies Capital Company, L.P. ("Cogen Capital"), in which the
McNair Interests have a 1% general partner and an approximate 81% limited
partner interest, charges Camden GPLP, Linden Ltd., NJ Inc. and Selkirk LP for
certain management, financial and administrative support services. Such fees
totaled: (i) Camden GPLP--$4.3 million in 1997, $2.9 million in 1996 and $2.6
million in 1995; (ii) Linden Ltd.--$21.2 million in 1997, $13.7 million in
1996 and $12.5 million in 1995; (iii) NJ Inc.--$5.2 million in 1997, $3.3
million in 1996 and $3.0 million in 1995 and (iv) Selkirk LP--$0.2 million in
each of 1997, 1996 and 1995. The costs of such services are accumulated
primarily based on employee time allocations and are charged to specific
entities based on electricity generation capacity. NJ Inc. charged Cogen
Capital $2.2 million in 1997, $2.0 million in 1996 and $1.7 million in 1995
for certain management, financial and administrative support services. The
costs of such services are accumulated primarily based on employee time
allocations.     
   
  Selkirk LP pays a natural gas management fee of $0.02 per thousand cubic
feet of natural gas purchased to a limited partner in certain of the entities
which comprise the Group. Fees for such services totaled $0.3 million in each
of 1997, 1996 and 1995.     
   
  Linden Ltd. has advanced funds to Cogen Technologies Financial Services,
L.P. ("Financial Services"), an investment company which is controlled by the
McNair Interests, which amounted to $160.8 million and $168.6 million at
December 31, 1997 and 1996, respectively. Such amount is classified as a long-
term receivable in the combined balance sheets (net of a $10.3 million
allowance at December 31, 1996). The receivable bears interest at 8.8% and
Linden Ltd. has earned net interest of $14.6 million in 1997, $15.6 million in
1996 and $16.8 million in 1995.     
   
  Financial Services has used the funds to make advances to other affiliates
for general working capital needs and has invested in treasury notes, treasury
bills and certain marketable securities. The market value of Financial
Services' investments in marketable securities, which is the only liquid asset
the partnership holds, supports Financial Services' ability to repay the
amounts advanced by Linden Ltd. In those instances when the market value of
Financial Services' marketable securities is below the amount of Linden Ltd.'s
receivable, creating doubt about the collectibility of the receivable, Linden
Ltd. provides a valuation allowance to reflect the shortfall. To the extent
the market value of the underlying marketable securities recovers, the
provision is reversed. Linden Ltd. recorded provisions (reversal of
provisions) with respect to its receivable from Financial Services of $(10.3
million) in 1997, $10.3 million in 1996 and $(6.5 million) in 1995. At
December 31, 1997 the cumulative allowance recognized with respect to such

  In 1995 NJ Inc. settled a tax dispute with the state of New Jersey for an
amount less than anticipated. The excess of the amount accrued over the
settlement amount, $1.3 million, was reflected as a benefit in 1995.
 
(6) COMMITMENTS AND CONTINGENCIES
 
  Six plaintiffs, individually on behalf of themselves and as representatives
of a class of persons similarly situated, filed an environmental lawsuit in
Louisiana state court against 92 defendants, including McNair Transport, Inc.
(predecessor to MESC). In the lawsuit, plaintiffs allege that defendants
caused environmental contamination at two sites in Iberville Parish,
Louisiana. Plaintiffs, who are alleged to have worked at the sites or resided
near the sites, claim personal injuries, increased risk and fear of future
disease, and property damage. Plaintiffs seek actual and exemplary damages of
an unspecified amount.
 
  Defendants removed the case to federal court, and the lawsuit is currently
pending in the United States District Court for the Middle District of
Louisiana. Defendants' motion to deny class certification is pending before
the court, and discovery on the merits of the case has, therefore, not
formally begun. MESC, the successor by merger to McNair Transport, Inc., is
unable at this time to evaluate the merits of the plaintiffs' claims, if any,
or to estimate potential costs or liability.
 
  There are certain other claims and legal actions pending against the Group
and its equity investees. While the outcome of such proceedings cannot be
predicted with certainty, management does not expect these matters to have a
material adverse effect on the financial condition or results of operations of
the Group.
 
(7) FAIR VALUE OF FINANCIAL INSTRUMENTS
 
  SFAS No. 107 "Disclosures About Fair Value of Financial Instruments"
requires the disclosure, to the extent practicable, of the fair value of
financial instruments which are recognized or unrecognized in the balance
sheet. The fair value disclosed herein is not representative of the amount
that could be realized or settled, nor does the fair value amount consider tax
consequences, if any, of realization or settlement. The following table
reflects the fair value of long-term debt at December 31, 1997 and 1996 (in
millions of dollars):

              NOTES TO COMBINED FINANCIAL STATEMENTS--(CONTINUED)
 
  The fair value of fixed-rate long-term debt has been determined based on the
differential between the interest rates of long-term treasury securities of
equivalent maturities and the effective interest rates on the debt at the date
of the borrowing plus the interest rates on similar treasury securities at the
balance sheet date. With respect to floating rate debt, the carrying amount
approximates fair value due to the market-sensitive interest rate on such
debt.
 
  The carrying amount of current assets and liabilities are considered to be
reasonable estimates of their fair values due to their short-term nature. The
carrying amount of the long-term receivable from an affiliate is considered to
be a reasonable estimate of fair value since interest is earned at market
rates.

(9) EVENT (UNAUDITED) SUBSEQUENT TO THE DATE OF THE INDEPENDENT AUDITORS'
REPORT
       
          
  Through the following series of transactions (the "Formation Transactions"),
the Company intends to acquire certain interests from the McNair Interests and
the Minority Interests (dollar and share amounts are based on a Common Stock
Offering (as defined herein) price of $15.00 per share):     
     
    (i) The Company will issue 28.7 million shares of common stock with an
  estimated market value of $429.7 million in exchange for 49.9% of the
  general and limited partnership interests in Linden Ltd., which is the
  managing general partner of Linden Venture which owns and operates a 715-
  megawatt cogeneration facility in Linden, New Jersey;     
     
    (ii) The Company will issue 9.9 million shares of common stock with an
  estimated market value of $147.9 million plus $1.0 million in cash in
  exchange for 100% of the outstanding common stock of Camden Inc. and the
  limited partnership interests in Camden GPLP held by the Minority
  Interests. Camden Inc. is a Texas corporation that is the general partner
  of Camden GPLP, a Delaware partnership that is the managing general partner
  of Camden Cogen which owns and operates a 146-megawatt cogeneration
  facility in Camden, New Jersey;

              NOTES TO COMBINED FINANCIAL STATEMENTS--(CONTINUED)
     
    (iii) MESC, a Texas corporation owned approximately 82% by the McNair
  Interests and 18% by the Minority Interests, will be merged with Cogen
  Technologies Bayonne, Inc., a wholly owned subsidiary of the Company,
  pursuant to which merger Cogen Technologies Bayonne, Inc. will survive and
  the shareholders of MESC will receive 14.4 million shares of the Company's
  common stock with an estimated market value of $217.4 million. MESC's
  wholly owned subsidiary NJ, Inc. is the managing general partner of NJ
  Venture which owns and operates a 176-megawatt cogeneration facility in
  Bayonne, New Jersey.     
     
    (iv) The Company will issue 1.7 million shares of common stock with an
  estimated market value of $25.2 million in exchange for 100% of the limited
  and general partnership interests in Selkirk LP. All of such interests are
  held by the McNair Interests and the Minority Interests. Selkirk LP holds a
  78% limited partnership interest in Selkirk Cogen which owns and operates a
  345-megawatt cogeneration facility in Bethlehem, New York;     
     
    (v) The Company will issue 0.3 million shares of common stock with an
  estimated market value of $4.8 million in exchange for 100% of the common
  stock of CT Global, whose primary business is underwriting a portion of the
  insurance carried by NJ Venture, Camden Cogen and Linden Venture.     
     
    (vi) Linden Ltd. will borrow $291.0 million under the terms of the Bridge
  Loan with Morgan Stanley & Co. Incorporated and redeem its remaining
  general and limited partnership interests in consideration for the
  distribution of a $140.4 million account receivable and a $291.0 million in
  cash. The Bridge Loan will be evidenced by a subordinated promissory note
  in favor of Morgan Stanley, which note will bear interest at the rate of
  24% per annum. Immediately following the issuance of the Senior Notes (as
  discussed hereinafter), the Company will loan $291.0 million of the
  proceeds to Linden Ltd. for repayment of the Bridge Loan.     
   
  The Camden Inc. and Linden Ltd. transactions are structured in a manner so
as not to qualify for tax-free incorporation or tax-free reorganization
treatment for the McNair Interests and the Minority Interests, thereby
providing the Company with a step-up in tax basis to fair market value. The
inclusion in the Camden Inc. transaction of the $1.0 million in cash is
necessary to achieve such treatment. No cash consideration is necessary with
respect to the Linden Ltd. partnership interests.     
   
  Prior to the Formation Transactions, the ownership interests of the McNair
Interests and the Minority Interests in Linden Ltd., Camden Inc. and the
limited partnership interests in Camden GPLP, approximately 89.5% of MESC and
CT Global are identical. Following the Formation Transactions with respect to
such entities the ownership interests of the McNair Interests and the Minority
Interests in the Company will be identical to their prior interests in the
entities acquired. Accordingly, the Company's acquisition of Linden Ltd.,
Camden Inc. and the limited partnership interests in Camden GPLP,
approximately 89.5% of MESC and CT Global will be accounted for at historical
cost as a reorganization of entities under common control.     
   
  The acquisition of the 81.7% of the partnership interests in Selkirk LP held
by the McNair Interests will be accounted for at historical cost as a
reorganization of entities under common control. The acquisition of the 18.3%
of the partnership interests in Selkirk LP held by the Minority Interests and
the 10.5% of MESC for which the ownership of a portion of the Minority
Interests is not identical to that of the other entities, will be accounted
for as purchase transactions. The purchase price for the Selkirk LP interests
held by the Minority Interests and the 10.5% interest in MESC is $4.5 million
and $22.5 million, respectively.     
   
  The accounts of Linden Ltd., Camden Inc., MESC, Selkirk LP and CT Global
will be included in the Company's consolidated financial statements. The
Company's investments in Linden Venture, Camden Cogen, NJ Venture and Selkirk
Cogen will be accounted for using the equity method.

  Because the ownership interests are not identical among each of (i) MESC,
(ii) Selkirk LP and (iii) the aggregate of Linden Ltd., Camden Inc., the
limited partnership interests in Camden GPLP and CT Global, the valuation of
the interests acquired by the Company with respect to each of these three
groups was agreed to in arms-length negotiations. The allocation of the
aggregate valuation among Linden Ltd., Camden Inc., the limited partnership
interests in Camden GPLP and CT Global for purposes of determining their new
tax bases and the amounts necessary to redeem 50.1% of the general and limited
partnership interests in Linden Ltd. is based upon their relative fair market
values. The price per share is equal to the Common Stock Offering price.     
   
  Following the Formation Transactions, the Company will hold, directly or
indirectly, 100% of the general and limited partnership interests of Camden
GPLP, Linden Ltd. and Selkirk LP and 100% of the common stock of NJ Inc. The
Company's interest in the earnings and cash distributions of NJ Venture,
Camden Cogen, Linden Venture and Selkirk Cogen is discussed in Note 2.     
          
  Following the Formation Transactions, the McNair Interests and the Minority
Interests intend to sell shares of the Company's common stock in the Common
Stock Offering. The Company will issue no shares and will receive no proceeds
from the Common Stock Offering. In connection with the Common Stock Offering,
the Company will pay certain costs which are estimated to total $1.8 million.
       
  Following the Formation Transactions, the Company intends to issue $400.0
million of Senior Notes, the proceeds from which will be used to loan an
amount to Linden Ltd. for repayment of the Bridge Loan, to retire amounts
payable to affiliates, to pay certain expenses related to the Formation
Transactions, the Common Stock Offering and the issuance of the Senior Notes
and for working capital purposes. The Senior Notes mature $100.0 million in
2005, $150.0 million in 2010 and $150.0 million in 2018 and are expected to
bear interest at approximately 6.72%, 6.89% and 7.33% per annum, respectively.
The Senior Notes have no sinking fund requirements and no principal payments
are required prior to maturity.     
   
  The Senior Notes will be secured, on an equal basis with the senior secured
bank indebtedness, by a security interest granted by the Company on certain
direct wholly-owned subsidiaries of the Company, which subsidiaries own all of
the Company's equity interests in the ventures. The Indenture to be executed
in conjunction with the Debt Offering will contain certain covenants,
including restrictive covenants that (i) limit indebtedness of the Company,
other than the Senior Notes, up to $300.0 million at any one time outstanding
in senior secured bank indebtedness, certain other parity indebtedness the
issuance of which either is incurred in compliance with a coverage ratio
requirement or will not result in a rating downgrade of the Senior Notes and
subordinated indebtedness, (ii) limit additional indebtedness of the ventures
(except Selkirk Venture) in which the Company currently has an interest, other
than up to $100.0 million at any one time outstanding for plant improvements
and expansion and amounts required to satisfy any fiduciary responsibilities
of the partners or venturers of each of the ventures, and (iii) prohibit
distributions to stockholders and on account of subordinated indebtedness owed
to affiliates unless no default exists under the Indenture and such
distributions do not exceed 100% of Funds From Operations (as of the closing
date of the issuance of the Senior Notes) plus $50.0 million. The Indenture
will further contain provisions that upon achieving a prescribed level of
diversification of interests owned by the Company in at least eight power
project ventures, the foregoing security interests, mandatory redemption
provisions and covenants and, subject to a further condition, security
interest, and certain events of default, will be permanently terminated. The
closings of each of the Common Stock Offering and the Debt Offering are
conditioned upon the consummation of the other.     
   
  Because the operations of the Company following the Formation Transactions
will be conducted primarily by its subsidiaries and ultimately by the ventures
in which the subsidiaries have interests, the Company's cash flow and its
ability to service indebtedness, including its ability to pay the interest on
and principal of its indebtedness and to pay dividends on the Common Stock,
will depend entirely upon the earnings of the ventures and the subsidiaries
and the distribution of those earnings to the Company. The Company initially
will have no

              NOTES TO COMBINED FINANCIAL STATEMENTS (UNAUDITED)
 
(1) ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
 Organization and Nature of Operations
   
  The combined financial statements of the Cogen Technologies Group (the
"Group") includes McNair Energy Services Corp. ("MESC") and its wholly owned
subsidiary Cogen Technologies NJ, Inc. ("NJ Inc."), Cogen Technologies Camden,
Inc. ("Camden Inc."), Cogen Technologies Linden, Ltd. ("Linden Ltd."), Cogen
Technologies Selkirk LP ("Selkirk LP"), CT Global Insurance, Ltd. ("CT
Global") and the limited partnership interests in Cogen Technologies Camden GP
Limited Partnership ("Camden GPLP") not held by Camden Inc. All material
transactions between the combined entities have been eliminated.     
 
  MESC is a Texas corporation that is owned approximately 82% by Robert C.
McNair, members of his immediate family and related trusts (the "McNair
Interests") and owns 100% of NJ Inc., a Delaware corporation. NJ Inc. provides
planning, operational and financial management services as managing general
partner for Cogen Technologies NJ Venture ("NJ Venture"), a New Jersey general
partnership that owns and operates a 176-megawatt cogeneration facility in
Bayonne, New Jersey. Under the terms of NJ Venture's joint venture agreement,
NJ Inc. is allocated 86.5% of NJ Venture's profits and losses and receives
86.5% of all cash distributions.
 
  Camden Inc. is a Texas corporation that is owned 100% by the McNair

megawatt cogeneration facility in Camden, New Jersey.
 
  Under the terms of Camden Cogen's partnership agreement, monthly cash
distributions are allocated 1% to Camden GPLP and 99% to the limited partner
up to a specified cumulative rate of return (approximately $0.3 million to
$0.4 million per month through May 2007 and varying amounts thereafter) and
the remaining available cash for the month is allocated 99% to Camden GPLP and
1% to the limited partner. Once the limited partner has received its specified
rate of return, cash distributions will be allocated 90% to Camden GPLP and
10% to the limited partner. During 1997, 1996 and 1995 Camden GPLP received
74%, 83% and 84%, respectively, of Camden Cogen's cash distributions. Camden
Cogen's income before depreciation is allocated as follows: (i) an amount
equal to debt principal payments, 100% to the limited partner; (ii) an amount
equal to and allocated on the same basis as cash distributed; and (iii) any
remainder generally 99% to Camden GPLP and 1% to the limited partner. Losses
are allocated 100% to Camden GPLP until its capital account equals zero and
then to the limited partner until its capital account equals zero and then to
Camden GPLP. Depreciation is allocated 100% to the limited partner until its
capital account equals zero and then to Camden GPLP. During 1997, 1996 and
1995 Camden GPLP was allocated 91%, 94% and 97%, respectively, of Camden
Cogen's net income.
 
  Linden Ltd. is a Texas limited partnership whose general partner, Cogen
Technologies, Inc. ("Cogen"), is owned 100% by the McNair Interests. Under the
terms of Linden Ltd.'s partnership agreement, Cogen is allocated 82% of Linden
Ltd.'s profits and losses and receives 82% of all cash distributions. Linden
Ltd. provides planning, operational and financial management services as
managing general partner of Cogen Technologies Linden Venture, LP ("Linden
Venture"), a Delaware limited partnership that owns and operates a 715-
megawatt cogeneration facility in Linden, New Jersey.
 
  Under the terms of Linden Venture's partnership agreement, cash is
distributed monthly, 1% to Linden Ltd. and 99% to the limited partner up to a
specified rate of return (approximately $4.3 million per month through
September 1998, approximately $3.0 million per month from October 1998 through
September 2001 and

              NOTES TO COMBINED FINANCIAL STATEMENTS--(CONTINUED)

between $4.3 million and $4.8 million per month thereafter) ("Tranche 1"),
then 99% to Linden Ltd. and 1% to the limited partner up to a capped amount,
which is twice the amount of Tranche 1, and the remainder 90% to Linden Ltd.
and 10% to the limited partner. During 1997, 1996 and 1995 Linden Ltd.
received 59%, 60% and 54%, respectively, of Linden Venture's cash
distributions. Linden Venture's income before depreciation is allocated to the
partners on the basis of cash distributed with any excess primarily allocated
99% to Linden Ltd. Losses are allocated 100% to Linden Ltd. until its capital
account equals zero and then to the limited partner until its capital account
equals zero with any remainder allocated 100% to Linden Ltd. Depreciation up
to $525.0 million is allocated 5% to Linden Ltd. and 95% to the limited
partners. All remaining depreciation is allocated 99% to Linden Ltd. During
1997, 1996 and 1995 Linden Ltd. was allocated 70%, 71% and 66%, respectively,
of Linden Venture's net income.
   
  Selkirk LP is a Delaware limited partnership in which the McNair Interests
hold a 1% general partner interest and an approximate 81% limited partner
interest. Selkirk LP holds a 78% limited partnership interest in Selkirk Cogen
Partners, L.P. ("Selkirk Cogen"), a Delaware limited partnership which owns
and operates a 345-megawatt cogeneration facility in Bethlehem, New York.     
   
  Under the terms of Selkirk Cogen's amended partnership agreement, available
cash is distributed, up to a specified level (the "Level 1 Distributions"),
99% to the partners in accordance with their current equity interests and 1%
in accordance with the original ownership structure (which does not include
Selkirk LP). Any additional funds are distributed 99% in accordance with the
original ownership structure and 1% to the partners in accordance with their
current equity interests. Subsequent to the earlier of September 1, 2013 or
the date all Level 1 Distributions are made, distributions will be made based
on the partners' residual interest (17.3% for the interest of Selkirk LP).
Under the terms of the amended partnership agreement, Selkirk LP is being
allocated a total of approximately 6% of the earnings of Selkirk Cogen.     
 
  The Group's investments in NJ Venture, Camden Cogen, Linden Venture and
Selkirk Cogen are accounted for using the equity method of accounting since
the limited partners have substantive participating rights with respect to the
partnerships' operations.
 
  CT Global is a Bermuda corporation owned approximately 82% by the McNair
Interests whose primary business is underwriting a portion of the insurance
carried by NJ Venture, Camden Cogen and Linden Venture.
 
  The accompanying unaudited financial statements of the Group reflect, in the
opinion of management, all adjustments, consisting only of normal and
recurring adjustments, necessary to present fairly the Group's financial
position at March 31, 1998 and the Group's results of operations and cash
flows for the three-month periods ended March 31, 1998 and 1997. Interim
period results are not necessarily indicative of the results of operations or
cash flows for a full-year period.
 
  These financial statements and the notes thereto should be read in
conjunction with the Group's audited financial statements included elsewhere
in this Prospectus.
 
(2) FORMATION OF COGEN TECHNOLOGIES, INC.
       
          
  Through the Formation Transactions, the Company intends to acquire certain
interests from the McNair Interests and the Minority Interests (dollar and
share amounts are based on a Common Stock Offering (as defined herein) price
of $15.00 per share):     
     
    (i) The Company will issue 28.7 million shares of common stock with an
  estimated market value of $429.7 million in exchange for 49.9% of the
  general and limited partnership interests in Linden Ltd., which is the
  managing general partner of Linden Venture which owns and operates a 715-
  megawatt cogeneration facility in Linden, New Jersey;     
 
                                     F-31
<PAGE>
 
                           COGEN TECHNOLOGIES GROUP
 
              NOTES TO COMBINED FINANCIAL STATEMENTS--(CONTINUED)
     
    (ii) The Company will issue 9.9 million shares of common stock with an
  estimated market value of $147.9 million plus $1.0 million in cash in
  exchange for 100% of the outstanding common stock of Cogen Technologies
  Camden Inc. and the limited partnership interests in Camden GPLP held by
  the Minority Interests. Camden Inc. is a Texas corporation that is the
  general partner of Camden GPLP, a Delaware partnership that is the managing
  general partner of Camden Cogen which owns and operates a 146-megawatt
  cogeneration facility in Camden, New Jersey;     
     
    (iii) MESC, a Texas corporation owned approximately 82% by the McNair
  Interests and 18% by the Minority Interests, will be merged with Cogen
  Technologies Bayonne, Inc., a wholly owned subsidiary of the Company,
  pursuant to which merger Cogen Technologies Bayonne, Inc. will survive and
  the shareholders of MESC will receive 14.4 million shares of the Company's
  common stock with an estimated market value of $217.4 million. MESC's
  wholly owned subsidiary Cogen Technologies NJ, Inc. ("NJ Inc.") is the
  managing general partner of NJ Venture which owns and operates a 176-
  megawatt cogeneration facility in Bayonne, New Jersey.     
     
    (iv) The Company will issue 1.7 million shares of common stock with an
  estimated market value of $25.2 million in exchange for 100% of the limited
  and general partnership interests in Selkirk LP. All of such interests are
  held by the McNair Interests and the Minority Interests. Selkirk LP holds a
  78% limited partnership interest in Selkirk Cogen which owns and operates a
  345-megawatt cogeneration facility in Bethlehem, New York;     
     
    (v) The Company will issue 0.3 million shares of common stock with an
  estimated market value of $4.8 million in exchange for 100% of the common
  stock of CT Global, whose primary business is underwriting a portion of the
  insurance carried by NJ Venture, Camden Cogen and Linden Venture.     
     
    (vi) Linden Ltd. will borrow $291.0 million under the terms of the Bridge
  Loan with Morgan Stanley & Co. Incorporated and redeem its remaining
  general and limited partnership interests in consideration for the
  distribution of a $140.4 million account receivable and a $291.0 million in
  cash. The Bridge Loan will be evidenced by a subordinated promissory note
  in favor of Morgan Stanley, which note will bear interest at the rate of
  24% per annum. Immediately following the issuance of the Senior Notes (as
  discussed hereinafter), the Company will loan $291.0 million of the
  proceeds to Linden Ltd. for repayment of the Bridge Loan.     
   
  The Camden Inc. and Linden Ltd. transactions are structured in a manner so
as not to qualify for tax-free incorporation or tax-free reorganization
treatment for the McNair Interests and the Minority Interests, thereby
providing the Company with a step-up in tax basis to fair market value. The
inclusion in the Camden Inc. transaction of the $1.0 million in cash is
necessary to achieve such treatment. No cash consideration is necessary with
respect to the Linden Ltd. partnership interests.     
   
  Prior to the Formation Transactions, the ownership interests of the McNair
Interests and the Minority Interests in Linden Ltd., Camden Inc. and the
limited partnership interests in Camden GPLP, approximately 89.5% of MESC and
CT Global are identical. Following the Formation Transactions with respect to
such entities the ownership interests of the McNair Interests and the Minority
Interests in the Company will be identical to their prior interests in the
entities acquired. Accordingly, the Company's acquisition of Linden Ltd.,
Camden Inc. and the limited partnership interests in Camden GPLP,
approximately 89.5% of MESC and CT Global will be accounted for at historical
cost as a reorganization of entities under common control.     
   
  The acquisition of the 81.7% of the partnership interests in Selkirk LP held
by the McNair Interests will be accounted for at historical cost as a
reorganization of entities under common control. The acquisition of the 18.3%
of the partnership interests in Selkirk LP held by the Minority Interests and
the 10.5% of MESC for which     
 
                                     F-32
<PAGE>
 
                           COGEN TECHNOLOGIES GROUP
 
              NOTES TO COMBINED FINANCIAL STATEMENTS--(CONTINUED)
   
the ownership of a portion of the Minority Interests is not identical to that
of the other entities, will be accounted for as purchase transactions. The
purchase price for the Selkirk LP interests held by the Minority Interests and
the 10.5% interest in MESC is $4.5 million and $22.5 million, respectively.
       
  The accounts of Linden Ltd., Camden Inc., MESC, Selkirk LP and CT Global
will be included in the Company's consolidated financial statements. The
Company's investments in Linden Venture, Camden Cogen, NJ Venture and Selkirk
Cogen will be accounted for using the equity method.     
   
  Because the ownership interests are not identical among each of (i) MESC,
(ii) Selkirk LP and (iii) the aggregate of Linden Ltd., Camden Inc., the
limited partnership interests in Camden GPLP and CT Global, the valuation of
the interests acquired by the Company with respect to each of these three
groups was agreed to in arms-length negotiations. The allocation of the
aggregate valuation among Linden Ltd., Camden Inc., the limited partnership
interests in Camden GPLP and CT Global for purposes of determining their new
tax bases and the amounts necessary to redeem 50.1% of the general and limited
partnership interests in Linden Ltd. is based upon their relative fair market
values. The price per share is equal to the Common Stock Offering price.     
   
  Following the Formation Transactions, the Company will hold, directly or
indirectly, 100% of the general and limited partnership interests of Camden
GPLP, Linden Ltd. and Selkirk LP and 100% of the common stock of NJ Inc. The
Company's interest in the earnings and cash distributions of NJ Venture,
Camden Cogen, Linden Venture and Selkirk Cogen is discussed in Note 1.     
   
  Following the Formation Transactions, the McNair Interests and the Minority
Interests intend to sell shares of the Company's common stock in the Common
Stock Offering. The Company will issue no shares and will receive no proceeds
from the Common Stock Offering. In connection with the Common Stock Offering,
the Company will pay certain costs which are estimated to total $1.8 million.
       
  Following the Formation Transactions, the Company intends to issue $400.0
million of Senior Notes, the proceeds from which will be used to loan an
amount to Linden Ltd. for repayment of the Bridge Loan, to retire amounts
payable to affiliates, to pay certain expenses related to the Formation
Transactions, the Common Stock Offering and the issuance of the Senior Notes
and for working capital purposes. The Senior Notes mature $100.0 million in
2005, $150.0 million in 2010 and $150.0 million in 2018 and are expected to
bear interest at approximately 6.72%, 6.89% and 7.33% per annum, respectively.
The Senior Notes have no sinking fund requirements and no principal payments
are required prior to maturity.     
   
  The Senior Notes will be secured, on an equal basis with the senior secured
bank indebtedness, by a security interest granted by the Company on certain
direct wholly-owned subsidiaries of the Company, which subsidiaries own all of
the Company's equity interests in the ventures. The Indenture to be executed
in conjunction with the Debt Offering will contain certain covenants,
including restrictive covenants that (i) limit indebtedness of the Company,
other than the Senior Notes, up to $300.0 million at any one time outstanding
in senior secured bank indebtedness, certain other parity indebtedness the
issuance of which either is incurred in compliance with a coverage ratio
requirement or will not result in a rating downgrade of the Senior Notes and
subordinated indebtedness, (ii) limit additional indebtedness of the ventures
(except Selkirk Venture) in which the Company currently has an interest, other
than up to $100.0 million at any one time outstanding for plant improvements
and expansion and amounts required to satisfy any fiduciary responsibilities
of the partners or venturers of each of the ventures, and (iii) prohibit
distributions to stockholders and on account of subordinated indebtedness owed
to affiliates unless no default exists under the Indenture and such
distributions do not exceed 100% of Funds From Operations (as of the closing
date of the issuance of the Senior Notes) plus $50.0 million. The Indenture
will further contain provisions that upon achieving a prescribed level of
diversification of interests owned by the Company in at least eight power
project ventures, the foregoing security interests, mandatory redemption
provisions and covenants and, subject to a further condition, security
interest, and certain events of default, will be permanently terminated. The
closings of each of the Common Stock Offering and the Debt Offering are
conditioned upon the consummation of the other.

                           COGEN TECHNOLOGIES GROUP
 
              NOTES TO COMBINED FINANCIAL STATEMENTS--(CONTINUED)
   
  Because the operations of the Company following the Formation Transactions
will be conducted primarily by its subsidiaries and ultimately by the ventures
in which the subsidiaries have interests, the Company's cash flow and its
ability to service indebtedness, including its ability to pay the interest on
and principal of its indebtedness and to pay dividends on the Common Stock,
will depend entirely upon the earnings of the ventures and the subsidiaries
and the distribution of those earnings to the Company. The Company initially
will have no significant business other than its ownership interests in the
subsidiaries and its planned development and acquisition business. The future
earnings of the ventures will be affected by a number of factors, including
competition in the power generation industry, possible changes in existing
laws and regulations, possible amendment or termination of the ventures' above
market power purchase agreements and various other economic, regulatory and
operating factors.     
          
  Certain executive officers of the Company will also serve as directors or
executive officers, or both, of certain other entities controlled by Mr.
McNair. In addition, the Company expects to provide certain management,
financial and administrative support services to such other entities
controlled by Mr. McNair. For such services the Company will receive a fee
equal to the Company's estimated cost plus an appropriate markup. The
Company's estimated cost, including office space and facilities, will be
determined on a full allocation basis, including employee salaries and
benefits and direct charges.     
 
(3) COMMITMENTS AND CONTINGENCIES
 
  Six plaintiffs, individually on behalf of themselves and as representatives
of a class of persons similarly situated, filed an environmental lawsuit in
Louisiana state court against 92 defendants, including McNair Transport, Inc.
(predecessor to MESC). In the lawsuit, plaintiffs allege that defendants
caused environmental contamination at two sites in Iberville Parish,
Louisiana. Plaintiffs, who are alleged to have worked at the sites or resided
near the sites, claim personal injuries, increased risk and fear of future
disease, and property damage. Plaintiffs seek actual and exemplary damages of
an unspecified amount.
 
  Defendants removed the case to federal court, and the lawsuit is currently
pending in the United States District Court for the Middle District of
Louisiana. Defendants' motion to deny class certification is pending before
the court, and discovery on the merits of the case has, therefore, not
formally begun. MESC, the successor by merger to McNair Transport, Inc., is
unable at this time to evaluate the merits of the plaintiffs' claims, if any,
or to estimate potential costs or liability.
 
  There are certain other claims and legal actions pending against the Group
and its equity investees. While the outcome of such proceedings cannot be
predicted with certainty, management does not expect these matters to have a
material adverse effect on the financial condition or results of operations of
the Group.
 
(4) SUBSEQUENT EVENTS
   
  To benefit the future results of operations of the Company by eliminating
the expense related to certain existing management services and gas management
services agreements and development bonuses, the McNair Interests and the
Minority Interests will provide the funding to terminate such agreements and
to "buy out" the development bonuses. In connection with the Formation
Transactions Linden Venture and Camden Cogen will terminate management
services agreements with Linden Ltd. and Camden GPLP, respectively, and Linden
Venture, Camden Cogen and Selkirk LP will terminate gas management services
agreements with an individual who is one of the Minority Interests in
consideration of a termination fee to such individual. Linden Ltd., Camden
GPLP and Selkirk LP will terminate management services agreements with RCM
Management Services L.P. ("RCM"), a Delaware limited partnership that is
indirectly owned and controlled by Robert C. McNair. In consideration for the
termination of these agreements a termination fee will be paid to RCM.

                           COGEN TECHNOLOGIES GROUP
 
              NOTES TO COMBINED FINANCIAL STATEMENTS--(CONTINUED)
   
  To terminate such agreements, the McNair Interests and the Minority
Interests will make capital contributions and Linden Venture, Camden Cogen and
Selkirk LP will make one-time payments totaling $83.7 million. Such payments
will be reflected in earnings in the period in which the payments are made.
Such payments will have no effect on the Group's liquidity or financial
condition since the amounts necessary to make such payments is being provided
by the shareholders and/or general and limited partners. The services
currently performed under such agreements will be assumed by existing Company
personnel.     
   
  In addition, one-time payments have been or will be made to "buy out"
development bonuses, which certain employees are eligible to receive in
subsequent periods. Such payments totaled $13.3 million in the first six
months of 1998 and additional payments to be made prior to or in connection
with the consummation of the Formation Transactions are expected to total
$14.9 million.     
   
  In July 1998 NJ Inc. purchased an additional 5.25% limited partnership
interest in NJ Venture for $12.5 million in cash from an unaffiliated party.
On a pro forma basis, assuming the transaction took place on January 1, 1997,
such transaction would have increased the Group's equity in the earnings of NJ
Venture for the six months ended June 30, 1998 and the year ended December 31,
1997 by $1.3 million and $0.8 million, respectively, and the Group's net
income for such periods by $0.8 million and $0.5 million, respectively.

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To Cogen Technologies New Jersey Operating Partnerships:
 
  We have audited the accompanying combined balance sheets of Cogen
Technologies New Jersey Operating Partnerships (a group of cogeneration
partnerships in which Robert C. McNair and affiliates have an interest) as of
December 31, 1997 and 1996, and the related combined statements of income,
partners' capital and cash flows for each of the three years in the period
ended December 31, 1997. These financial statements are the responsibility of
the partnerships' management. Our responsibility is to express an opinion on
these financial statements based on our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Cogen Technologies New
Jersey Operating Partnerships as of December 31, 1997 and 1996, and the
results of their operations and their cash flows for each of the three years
in the period ended December 31, 1997, in conformity with generally accepted
accounting principles.

             COGEN TECHNOLOGIES NEW JERSEY OPERATING PARTNERSHIPS
 
                    NOTES TO COMBINED FINANCIAL STATEMENTS
 
(1) ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
 Organization and Nature of Operations
 
  The combined financial statements of the Cogen Technologies New Jersey
Operating Partnerships (the "NJ Partnerships") includes (i) Cogen Technologies
NJ Venture ("NJ Venture"); (ii) Camden Cogen LP ("Camden Cogen"); and (iii)
Cogen Technologies Linden Venture, LP ("Linden Venture"). The NJ Partnerships
are engaged in the operation of natural gas-fired cogeneration facilities in
the state of New Jersey. The financial statements of the NJ Partnerships are
presented on a combined basis since all such entities were under common equity
ownership and management by general partners that are under the common control
of the McNair Interests (as defined herein). All material transactions between
the combined entities have been eliminated.
 
  NJ Venture, a New Jersey general partnership, owns and operates a 176-
megawatt cogeneration facility in Bayonne, New Jersey. Cogen Technologies NJ
Inc. ("NJ Inc."), a Delaware corporation which is owned 100% by McNair Energy
Services Corp. (a Texas corporation that is owned approximately 82% by Robert
C McNair, members of his immediate family and related trusts [the "McNair
Interests"]), is the managing partner of NJ Venture and provides planning,
operational and financial management services. Under the terms of NJ Venture's
joint venture agreement, NJ Inc. is allocated 86.5% of NJ Venture's profits
and losses and receives 86.5% of all cash distributions.
 
  Camden Cogen, a Delaware limited partnership, owns and operates a 146-
megawatt cogeneration facility in Camden, New Jersey. Cogen Technologies
Camden GP Limited Partnership ("Camden GPLP"), whose 82% general partner is
owned 100% by the McNair Interests, is the managing partner of Camden Cogen
and provides planning, operational and financial management services. Under
the terms of Camden Cogen's partnership agreement, monthly cash distributions
are allocated 99% to the limited partner and 1% to Camden GPLP up to a
specified cumulative rate of return (approximately $0.3 million to $0.4
million per month through May 2007 and varying amounts thereafter) and the
remaining available cash for the month is allocated 99% to Camden GPLP and 1%
to the limited partner. Once the limited partner has received its specified
rate of return, cash distributions will be allocated 90% to Camden GPLP and
10% to the limited partner. During 1997, 1996 and 1995 Camden GPLP received
$8.6 million, $14.5 million and $15.0 million, respectively, which represented
74%, 83% and 84%, respectively, of Camden Cogen's cash distributions. Camden
Cogen's income before depreciation is allocated as follows: (i) an amount
equal to debt principal payments, 100% to the limited partner; (ii) an amount
equal to and allocated on the same basis as cash distributed; and (iii) any
remainder is generally allocated 99% to Camden GPLP and 1% to the limited
partner. Losses are allocated 100% to Camden GPLP until its capital account
equals zero and then 100% to the limited partner until its capital account
equals zero and then 100% to Camden GPLP. Depreciation is allocated 100% to
the limited partner until its capital account equals zero and then to Camden
GPLP. During 1997, 1996 and 1995 Camden GPLP was allocated 91%, 94% and 97%,
respectively, of Camden Cogen's net income.
 
  Linden Venture, a Delaware limited partnership, owns and operates a 715-
megawatt cogeneration facility in Linden, New Jersey. Cogen Technologies
Linden Ltd. ("Linden Ltd."), whose 82% general partner is owned 100% by the
McNair Interests, is the managing partner of Linden Venture and provides
planning, operational and financial management services. Under the terms of
Linden Venture's partnership agreement, cash is distributed monthly, 1% to
Linden Ltd. and 99% to the limited partner up to a specified rate of return
(approximately $4.3 million per month through September 1998, approximately
$3.0 million per month from October 1998 through September 2001 and between
$4.3 million and $4.8 million per month thereafter) ("Tranche 1"), then 99% to
Linden Ltd. and 1% to the limited partner up to an amount equal to twice the
amount of Tranche 1 and the remainder 90% to Linden Ltd. and 10% to the
limited partner. During 1997, 1996 and 1995 Linden Ltd. received $75.6
million, $77.7 million and $59.4 million, respectively, which represented 59%,
60% and 54%, respectively, of Linden Venture's cash distributions. Linden
Venture's income before depreciation

             COGEN TECHNOLOGIES NEW JERSEY OPERATING PARTNERSHIPS
 
              NOTES TO COMBINED FINANCIAL STATEMENTS--(CONTINUED)
 
is allocated to the partners on the basis of cash distributed with any excess
primarily allocated 99% to Linden Ltd. Losses are allocated 100% to Linden
Ltd. until its capital account equals zero and then to the limited partners
until their capital accounts equal zero with any remainder allocated 100% to
Linden Ltd. Depreciation up to $525.0 million is allocated 5% to Linden Ltd.
and 95% to the limited partners. All remaining depreciation is allocated 99%
to Linden Ltd. During 1997, 1996 and 1995 Linden Ltd. was allocated 70%, 71%
and 66%, respectively, of Linden Venture's net income.
 
  NJ Inc., Camden GPLP and Linden Ltd. are controlled by McNair.
 
 Cash and Cash Equivalents/Restricted Cash
 
  All highly liquid short-term investments with original maturities of three
months or less are considered to be cash equivalents. At December 31, 1997 and
1996, $23.3 million and $22.6 million, respectively, of the NJ Partnerships'
cash was held in accounts to secure certain current liabilities.
 
 Inventories
 
  Spare parts inventories at December 31, 1997 and 1996 were $16.5 million and
$12.0 million, respectively and at such date kerosene and butane inventories
were $4.7 million and $5.4 million, respectively. Inventories are valued at
average cost.
 
 Property, Plant and Equipment
 
  Property, plant and equipment is stated at cost. Depreciation is recorded
utilizing the straight-line method over the estimated useful life of the
facilities, which range from twenty to twenty-five years, with no salvage
value.
 
  During the first quarter of 1996 the NJ Partnerships adopted Statement of
Financial Accounting Standards ("SFAS") No. 121, "Accounting for the
Impairment of Long-Lived Assets and Long-Lived Assets to be Disposed of". SFAS
No.121 requires, among other things, that long-lived assets and certain
identifiable intangibles to be held and used by an entity be reviewed for
impairment whenever events or changes in circumstances indicate that the
carrying amount of an asset may not be recoverable. The application of SFAS
No. 121 has had no impact on the NJ Partnerships' financial position or
results of operations.
 
  Estimated costs associated with planned outages for major maintenance that
benefit more than one period are accrued in advance on a straight-line basis.
Routine and unplanned maintenance and repairs are expensed as incurred. For
the years ended December 31, 1997, 1996 and 1995, $13.7 million, $11.6 million
and $18.3 million, respectively, was charged to expense with respect to major
maintenance and routine maintenance and repairs.
 
 Revenue Recognition
 
  The NJ Partnerships operate under long-term power purchase agreements with
major utilities. Pursuant to the terms of such agreements, the utilities pay a
price per kilowatt hour for the entire term of the agreement that generally
includes: (i) a constant capacity rate per kilowatt hour; (ii) an inflation
component; and (iii) a fuel cost component. Accordingly, the NJ Partnerships
recognize electricity revenues at the above rates in the periods the
electricity is delivered.
 
  Steam revenues are recognized as they are earned pursuant to the underlying
sales agreements.
 
 Deferred Revenues
 
  Pursuant to the power purchase agreement between Consolidated Edison Company
of New York, Inc. ("ConEd") and Linden Venture, ConEd makes prepayments to
Linden Venture for butane inventory. At December 31, 1997 and 1996 such
prepayments totaled $2.2 million and $2.9 million, respectively, and are
 
                                     F-42

              NOTES TO COMBINED FINANCIAL STATEMENTS--(CONTINUED)
 
included in Other Long-Term Liabilities in the balance sheet. The butane
inventory is expensed and the revenue is recognized when the butane is
consumed.
 
 Income Taxes
 
  Income taxes with respect to the NJ Partnerships are not levied at the
partnership level but rather on the individual partners. Accordingly, no
income taxes have been recognized in the combined financial statements.
 
 Use of Estimates
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires the use of certain estimates and
assumptions that affect the reported amounts of assets and liabilities and the
disclosure of contingent assets and liabilities, if any, and the periods in
which certain items of revenue and expense are included. Actual results may
differ from such estimates.
 
(2) FINANCING AND DEBT
 
  Long-term debt at December 31, 1997 and 1996 consisted of the following (in
millions of dollars):

(4) COMMITMENTS AND CONTINGENCIES
 
 NJ Venture
 
  NJ Venture has contracted to sell approximately 76% of its electrical
capacity to Jersey Central Power & Light Company ("JCP&L") pursuant to a 20-
year power purchase agreement which expires in 2008, with a ten-year renewal
period subject to the approval of both parties. The agreement establishes the
sales price of the electricity based on a fixed rate component plus factors
for inflation and JCP&L's cost of natural gas and retail sales prices. The
remainder of NJ Venture's output is sold to PSE&G pursuant to a 20-year power
purchase agreement which expires in 2008, with two five-year renewal periods
subject to the approval of both parties. The agreement provides for payments
to NJ Venture consisting of a capacity payment plus an energy payment which
includes a fixed component plus factors for inflation and fuel costs.
 
  NJ Venture and PSE&G entered into a revised transmission service and
interconnection agreement (the "Transmission and Interconnection Agreement")
on April 27, 1987, under which PSE&G agreed to design, construct, own and
operate a 138 kilovolt underground transmission cable circuit and associated
terminal facilities (jointly the "Interconnection") to connect the Bayonne
Plant with PSE&G's Public Service System at PSE&G's Bayonne Switching Station.
The initial term of the agreement is 20 years. Upon the expiration of the
initial term, the Transmission and Interconnection Agreement shall
automatically be extended for a succeeding term of 10 years, unless either
party elects, upon three years' notice, to terminate the Transmission and
Interconnection Agreement at the close of the initial term.
 
  NJ Venture entered into an agreement for the sale of steam and electricity
(as amended, the "IMTT Steam Sale Agreement") with IMTT-Bayonne on June 13,
1985, which was amended on May 22, 1986. The IMTT Steam Sale Agreement
provides for the sale to IMTT-Bayonne of 100% of its steam needs at its tank
terminal facility, and at the venture's option, the sale of electricity. NJ
Venture has no current plans to offer IMTT-Bayonne electricity under the IMTT
Steam Sale Agreement. The IMTT Steam Sale Agreement has a base term of 10
years, which has expired, with automatic renewal thereafter for each following
year unless either party elects to terminate the agreement at the end of a
renewal year upon 60 days notice. IMTT-Bayonne agrees to purchase from NJ
Venture all of the thermal energy requirements of its tank terminal facility
up to the deemed maximum steam production of 57,000 lbs/hour according to a
pricing formula based on IMTT-Bayonne's avoided cost of steam.
 
  NJ Venture and Exxon entered into an Agreement for the Sale of Steam (the
"Exxon Steam Sale Agreement") on February 27, 1987, which was amended on
August 21, 1988. Under the terms of the Exxon Steam Sale Agreement, Exxon
agreed to purchase from the Bayonne Plant an average of 50,000 lbs/hour of
steam on an annualized basis. The Exxon Steam Sale Agreement provides for an
initial term of five years (now expired). Thereafter, the Exxon Steam Sale
Agreement continues on a year to year basis unless either party exercises its
rights to terminate as provided in the Exxon Steam Sale Agreement. Beginning
in the fifth year of the agreement, either party is entitled to serve written
notice on the other of its interest to terminate the agreement. The Exxon
Steam Sale Agreement would then terminate one year after the notice or at an
earlier date upon which the parties mutually agree. Exxon used the steam at
its adjacent terminal facility for industrial purposes. Exxon sold its
terminal facility in Bayonne to IMTT-BX on April 1, 1993. As a result, IMTT-BX
assumed Exxon's rights and obligations under the Exxon Steam Sale Agreement
and is currently performing under the agreement.

 Other
 
  There are certain claims and legal actions pending against the NJ
Partnerships. While the outcome of such proceedings cannot be predicted with
certainty, management does not expect these matters to have a material adverse
effect on the financial condition or results of operations of the NJ
Partnerships.
 
(5) MAJOR CUSTOMERS AND CONCENTRATION OF CREDIT RISK
 
 Major Customers
 
  The NJ Partnerships' operating revenues primarily relate to sales to three
customers pursuant to long-term contracts. The following table reflects
customers who accounted for more than 10% of the NJ Partnerships' revenues in
the years ended December 31, 1997, 1996 and 1995.

</TABLE>
 
 Concentration of Credit Risk
 
  Financial instruments which potentially subject the NJ Partnerships to
credit risk consist of cash and accounts receivable. Cash accounts are held by
major financial institutions. Accounts receivable are primarily concentrated
with the three major utilities which purchase the NJ Partnerships' electricity
under long-term agreements. The NJ Partnerships do not require collateral or
other security to support accounts receivable. Accounts receivable are net of
NJ Venture's allowance for doubtful accounts of $0.3 million at December 31,
1997 and Linden Venture's allowance for doubtful accounts of $1.2 million at
December 31, 1996. The NJ Partnerships have no other financial instruments
which subject them to credit risk.

(6) FAIR VALUE OF FINANCIAL INSTRUMENTS
 
  SFAS No. 107 "Disclosures About Fair Value of Financial Instruments"
requires the disclosure, to the extent practicable, of the fair value of
financial instruments which are recognized or unrecognized in the balance
sheet. The fair value disclosed herein is not representative of the amount
that could be realized or settled, nor does the fair value amount consider tax
consequences, if any, of realization or settlement. The following table
reflects the fair value of long-term debt at December 31, 1997 and 1996 (in
millions of dollars):

        NJ Venture................................   71.8   104.7   74.9   101.9
</TABLE>
 
  The fair value of fixed-rate long-term debt has been determined based on the
differential between the interest rates of long-term treasury securities of
equivalent maturities and the effective interest rates on the debt at the date
of the borrowing plus the interest rates on similar treasury securities at the
balance sheet date. With respect to floating rate debt, the carrying amount
approximates fair value due to the market-sensitive interest rate on such
debt.
 
  The fair value of Camden Cogen's interest rate swap is estimated to be $0.6
million, the approximate amount that GECC would pay to terminate the agreement
at December 31, 1997, based on interest rates in effect at that time.
 
  The carrying amount of current assets and liabilities are considered to be
reasonable estimates of their fair values due to their short-term nature.

             COGEN TECHNOLOGIES NEW JERSEY OPERATING PARTNERSHIPS
 
              NOTES TO COMBINED FINANCIAL STATEMENTS (UNAUDITED)
 
(1) ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
  The combined financial statements of the Cogen Technologies New Jersey
Operating Partnerships (the "NJ Partnerships") includes (i) Cogen Technologies
NJ Venture ("NJ Venture"); (ii) Camden Cogen LP ("Camden Cogen"); and (iii)
Cogen Technologies Linden Venture, LP ("Linden Venture"). The NJ Partnerships
are engaged in the operation of natural gas-fired cogeneration facilities in
the state of New Jersey. The financial statements of the NJ Partnerships are
presented on a combined basis since all such entities were under common equity
ownership and management by general partners that were under common control.
All material transactions between the combined entities have been eliminated.
   
  Effective January 1, 1998 the NJ Partnerships made certain changes in the
estimates used for the purpose of computing depreciation. The estimated useful
life of the facilities was increased from a range of 20 to 25 years, which
coincided with the primary term of the long-term power purchase agreements
under which the NJ Partnerships sell electricity, to 30 years. In addition,
the NJ Partnerships increased the estimated salvage value of the facilities
from zero to 10%. Such changes were made to recognize the usefulness of the
facilities beyond the primary term of the power purchase agreements and the
residual value of the facilities upon the termination of operations. Such
changes resulted in an increase in earnings in the first six months of 1998 of
$7.0 million ($3.5 million in the second quarter of 1998).     
   
  The accompanying unaudited financial statements of the NJ Partnerships
reflect, in the opinion of management, all adjustments, consisting only of
normal and recurring adjustments, necessary to present fairly the NJ
Partnerships' financial position at June 30, 1998 and the NJ Partnerships'
results of operations and cash flows for the three-month and six-month periods
ended June 30, 1998 and 1997. Interim period results are not necessarily
indicative of the results of operations or cash flows for a full-year period.
    
  These financial statements and the notes thereto should be read in
conjunction with the NJ Partnerships' audited financial statements included
elsewhere in this Prospectus.
 
(2) CONTINGENCIES
 
  There are certain claims and legal actions pending against the NJ
Partnerships. While the outcome of such proceedings cannot be predicted with
certainty, management does not expect these matters to have a material adverse
effect on the financial condition or results of operations of the NJ
Partnerships.
 
(3) SUBSEQUENT EVENTS
   
  In the second quarter of 1998 Linden Venture and Camden Cogen entered into
negotiations to make settlements to terminate existing management services
agreements with Linden Ltd. and Camden GPLP, respectively, and gas management
services agreements with an affiliate. Such negotiations were finalized in the
third quarter of 1998. To terminate such agreements, general and limited
partners will make capital contributions and Linden Venture and Camden Cogen
will make one-time payments totaling $66.8 million. Such payments will be
reflected in earnings in the third quarter of 1998. Such payments will have no
effect on the NJ Partnerships' liquidity or financial condition since the
amounts necessary to make such payments are being provided by the general and
limited partners.     
 
  In July 1998, in connection with an arbitration proceeding brought by Linden
Venture at the American Arbitration Association, which proceeding began in
1997, against Ebasco Constructors, Inc. and ENSERCH ("Respondents"),
Respondents filed a revised counterclaim against Linden Venture in the amount
of $16.0 million. Prior to the filing of such revised counterclaim, the
arbitration panel had reduced Linden Venture's claim against the Respondents
to $9.0 million and had reduced Respondents' initial counterclaim to $3.9
million. The initial claims brought by Linden Venture against Respondents were
for alleged design deficiencies and warranty claims with respect to the
construction of the Linden plant. The Respondents' counterclaim alleged delay
and disruption to the performance of the construction contract. While the
outcome of this proceeding cannot be predicted with certainty, management does
not expect this matter to have a material adverse effect on the financial
condition or results of operations of the NJ Partnerships.

   which Cogen will acquire equity interests pursuant to the Formation

 .  NJ Inc. is the managing partner of Cogen Technologies NJ Venture ("NJ
   Venture") which owns and operates the Bayonne Plant. Camden Inc. is the
   general partner of Camden GPLP, which is the general partner of Camden Cogen
   LP ("Camden Cogen") which owns and operates the Camden Plant. Linden Ltd. is

  The Company is engaged in the development, ownership, operation, acquisition
and financing of power generation facilities and the sale of electricity and
steam in the United States. The Company currently has interests in four power
plants having an aggregate nameplate capacity of 1,382 megawatts. In 1997,
these plants produced an aggregate 8,662,000 megawatt hours of electricity and
7,665 million pounds of steam.     
   
  The Company's principal assets consist of its substantial economic interests
in a 715 megawatt capacity Linden, New Jersey, cogeneration plant (the "Linden
Plant"), which sells its electric output to The Consolidated Edison Company of
New York, Inc. ("Con Ed") under a contract having an initial term expiring in
2017, a 176 megawatt capacity Bayonne, New Jersey, cogeneration plant (the
"Bayonne Plant"), which sells its electric output to Jersey Central Power &
Light Company ("JCP&L") and Public Service Electric and Gas Company of New
Jersey ("PSE&G"), under contracts having initial terms expiring in 2008 and a
146 megawatt capacity Camden, New Jersey, cogeneration plant (the "Camden
Plant"), which sells its electric output to PSE&G under a contract having an
initial term expiring in 2013. The Company has operating and maintenance
responsibility for the three principal plants and has contracted for the day-
to-day operation and maintenance of the plants with General Electric Company
("GE"). In addition, the Company has an equity investment in a 345 megawatt
capacity Bethlehem, New York cogeneration plant (the "Selkirk Plant"), which is
not economically material to the Company.     
 
INDUSTRY
   
  The Company is a participant in the highly competitive power generation
industry, which is among the largest industries in the United States, with an
estimated end-user market of over $200 billion of electricity sales and 3,400
gigawatt hours of production. New regulatory initiatives have been or currently
are being adopted or considered at the federal level and in approximately 45
states to increase competition in the domestic power generation industry. In
April 1996, the Federal Energy Regulatory Commission ("FERC") adopted Order No.
888, opening wholesale power sales to competition and providing for open and
fair electric transmission services by public utilities. At the state level,
industry restructuring is well advanced in various states including California,
Massachusetts, New York, New Jersey and Pennsylvania. This restructuring
includes deregulation of electric utilities and the introduction of customer
choice. The regulatory initiatives are expected to lead to the transformation
of the existing market, which is largely characterized by electric utility
monopolies, having old, inefficient, high-cost generating facilities, selling
to a captive customer base, to a more competitive market where end users may
purchase electricity from a variety of suppliers, including non-utility
generators, power marketers, public utilities and others.     
 
  The Company believes that these market trends will present substantial
opportunities for industry participants that are efficient and low-cost power
producers and are able to offer competitive rates to customers. The Company
believes that an additional opportunity is presented by the significant
deregulation and consolidation now affecting the power industry, which has
resulted in substantial divestitures of generation assets by traditional power
utilities and by certain independent power producers currently owning
relatively few plants. For example, as a result of regulatory initiatives,
approximately 14,000 megawatts of New York generating capacity have been sold
or offered for sale by utilities. Similar regulatory initiatives in New Jersey
and Pennsylvania are expected to cause utilities in those states to pursue
similar divestiture plans. At the same time, a number of industrial companies
have also announced plans to sell self-generation facilities and to re-deploy
the capital in their core businesses. These trends, which the Company believes
are likely to continue, should provide significant acquisition opportunities
for the Company.
 
  The Company also believes that attractive opportunities for development of
new generation assets will arise in the next few years, principally due to a
projected increase in baseload demand in the Northeast and Mid-Atlantic regions
and the retirement of a significant number of existing power generation
facilities which are 30 or more years old.

STRATEGY
 
  The Company's strategy is to maximize cash flow associated with its existing
power plants and to grow through expansion of the Company's existing operations
and through the acquisition and development of existing or new power generation
and related facilities. Specific aspects of this strategy are set-forth below:
 
 .  Maximize the Value of Existing Assets. The Company's high quality plant and
   equipment and long duration power sales agreements have provided it with
   stable long-term cash flow. In order to maintain the quality of these
   assets, and to further increase margins, the Company's core strategy
   includes continuous capital investment in current facilities to assure
   ongoing efficiency consistent with high rates of return on capital. In
   keeping with these objectives, the Company has systematically pursued
   technological upgrades and retrofits to existing plants which increase
   output or operating efficiency. As an example, the capacity of each of the
   nine gas turbines at the Linden, Camden and Bayonne Plants has been
   increased by approximately 2.5 megawatts per gas turbine. At the Camden
   Plant, an inlet chiller system recently was installed which increases the
   generation capacity of the plant by 32,000 megawatt hours per year. In
   addition to these improvements, the Company currently is considering a
   number of technology investments, some of which, if implemented, the Company
   expects will (i) reduce fuel costs at the Bayonne Plant, (ii) reduce water
   usage and associated expenses at the Camden Plant, (iii) generate additional
   steam sales and electrical output through modest expansion and the addition
   of equipment at the Camden Plant, (iv) reduce water costs at the Linden
   Plant and (v) increase electrical output through the use of chilled water
   equipment improvements at the Linden Plant. The Company will continue to
   seek to add value to its existing projects and its customers through
   mutually negotiated contractual and operating changes such as those changes
   successfully negotiated to Linden Venture's power purchase agreement with
   Con Ed in September 1990 and December 1993. The Company will continue to
   monitor, revise and replace its fuel supply arrangements to obtain a balance
   between immediate savings in gas and transportation costs and the need to
   maintain regular and secure relationships with various gas producers and
   transporters of gas.
 
 .  Expand Existing Plants. The Company believes that all three of the plants in
   which it has a substantial economic interest are capable of being expanded
   not only through additions to existing plants but also through the
   development and construction of new power plant facilities at the existing
   sites. In this regard, the Company has permit applications pending and
   presently is engaged in advanced strategic design work with respect to the
   addition of a new 250 megawatt unit at the Linden Plant with a view to
   utilizing such plant's direct interconnect with Con Ed in New York City.
   With respect to the Bayonne Plant, the Company is considering the
   installation of a new power facility at that location.
 
 .  Pursue Domestic Electricity Generation Acquisitions and Other Opportunities.
   The Company believes that it will have ample opportunities to grow its
   operations through acquisitions, development of new assets and through other
   means, whether on its own or through partnerships with companies that have
   complementary skills. This strategy is based on the Company's view that
   baseload demand for power will increase over the next few years, and that
   retirement of a significant number of existing plants will further spur the
   need for additional capacity. In addition, a number of utilities in the
   Northeastern United States have announced plans to divest power generating
   assets, including Con Ed, General Public Utilities, New York State Electric
   and Gas, and Niagara Mohawk Power Company. This development, together with
   expected further consolidation in the independent power industry, may offer
   the Company a number of opportunities to grow its business by making
   strategically significant acquisitions, with an initial focus in the
   Northeast. Longer term, the Company intends to continue to consider
   opportunities for new developments of power generation facilities in the
   Northeast and elsewhere in the United States. The Company has no plans for
   expansion into the international arena.

  The Company believes that the following competitive strengths will aid in the
successful implementation of its strategy:
 
 .  Efficient and Reliable Power Projects. The Company's three principal plants
   have well-established and consistent records of service to their customers.
   The average availability for all of these plants has exceeded 92% since
   placed in operation. This record of service is principally the result of the
   highly reliable combined-cycle technology, which generally is significantly
   more efficient than that of a majority of the existing utility generating
   facilities in the region, together with the operations and maintenance
   practices of the Company.
 
 .  Favorable Contracts and Stable Cash Flow. The utility power purchase
   contracts relating to the Company's three principal plants have long-term
   remaining lives, with expirations ranging from 2008 to 2017. For example,
   the Linden Plant has nameplate electric capacity of 715 megawatts and
   represents approximately 70% of the Company's power generating assets.
   Linden Venture has a power purchase agreement which expires in the year
   2017. In addition, all of the Company's existing power purchase agreements
   are with large utilities which presently have investment grade senior debt
   ratings. The Company's principal power plants historically have provided a
   consistent and substantial cash flow to equity holders due to the fixed
   payment components of the power purchase contracts which have provided
   favorable margins over the ventures' fixed operating and financing costs.
   Moreover, the variable energy payment components of such agreements, which
   provide the second major component of pricing under such agreements, have
   historically been well correlated to fuel costs at the Bayonne and Camden
   Plants and have reflected a partial pass-through mechanism for fuel expenses
   at the Linden Plant.
 
 .  Environmental Considerations. The Company's existing plants principally burn
   natural gas, which is a clean burning fuel, and they employ advanced
   environmental technology which makes them among the cleanest in the
   industry. The existing plants also are operated in compliance with
   applicable state and federal environmental regulations.
 
 .  Regional Expertise in Northeast Power Markets. As a result of the location
   of its existing assets and its active involvement in industry restructuring,
   the Company has developed significant expertise in Northeastern power
   markets. This expertise could provide the Company with a competitive
   advantage in pursuing additional opportunities within the region.
   
 .  Experienced Management. The Company's senior management team, led by the
   founder of the Company's predecessor companies, Robert C. McNair, has an
   aggregate of over 117 years of experience in the energy industry. The
   Company currently operates plant and equipment that is widely viewed to be
   among the safest and most environmentally advanced in the industry. The
   Company's philosophy is to maintain a small, well-qualified management team
   with expertise in all aspects of the independent power business, to actively
   participate in a broad range of regulatory affairs governing the industry
   and to retain additional experts in connection with the construction,
   maintenance and operation of its plants.     
 
 .  Disciplined Management Approach. The Company's management team has a
   demonstrated track record in developing innovative financial structures for
   its investments and has well-established criteria which govern its approach
   to both development of new plants and acquisitions.
 
 .  Strong Financial Position. The Company believes that its high quality
   assets, its federal income tax position and its long duration power supply
   contracts provide it with the financial strength to access the capital
   markets to obtain the capital needed to fund execution of its strategic
   plan.

FORMATION
 
  Cogen was incorporated in May 1998 at the instance of Robert C. McNair to
acquire operating control of three entities operating independent power plants
in New Jersey, together with an indirect equity interest in a fourth plant
operating in New York. Prior to the consummation of the Formation Transactions,
the Cogen ownership interests in the plants were 82% beneficially owned by Mr.
McNair and members of his family, and by entities controlled by his family (the
"McNair Interests"). The remaining 18% of such interests was beneficially held
by other persons or entities (the "Minority Interests") with no relation to the
McNair Interests. Upon consummation of the Formation Transactions, Cogen will
own the interests in the subsidiaries held by the McNair Interests and the
Minority Interests. See "Certain Transactions--Formation Transactions". The
following chart sets forth, in a simplified manner, the organizational
structure of the Company with respect to its interests in the ventures owning
the plants immediately following the consummation of the Formation
Transactions, eliminating certain intermediate entities that may be formed to
hold various interests.

    Formation Transactions.     
 
DIVIDEND POLICY
 
  Cogen plans to pay dividends on the Common Stock of approximately $    per
share per quarter. During the initial years of the Company's operations,
dividends with respect to the Common Stock are expected to exceed the share of
the current and accumulated earnings and profits of the Company allocable to
the holders of the Common Stock (as determined for United States federal income
tax purposes). In such a case, such excess generally would be treated as a tax-
free return of capital up to a holder's basis in such holder's shares of Common
Stock and as capital gain thereafter. See "Dividend Policy".
 
  The Company's principal executive office is located at 711 Louisiana, 33rd
Floor, Houston, Texas 77002, and its telephone number is 713/336-7700.

                                In addition, the First Supplemental Indenture
                                will permit Cogen to make dividend payments or

                                the Issue Date) plus $50 million, unless a
                                Default or Event of Default has occurred and is
                                continuing.
 
                                Upon the Covenant Modification Date, these
                                covenants will forever terminate and cease to
                                be in effect.
 
Covenant Modification Date..    The Covenant Modification Date shall mean the
                                day upon which (i) Cogen has a portfolio
                                comprising interests in at least eight power
                                projects with no single project contributing
                                more than 25% or less than 5% of aggregate Cash
                                Distributions (as defined herein) for each of
                                the four quarters preceding such date of
                                determination and the four quarters succeeding
                                such date of determination (as projected by
                                Cogen), as certified by both the Independent

                                Financial Officer (with forecasts relating to
                                merchant capacity reflecting cash flows for
                                such capacity over the previous four quarters)
                                and (ii) the then current ratings on the Senior
                                Notes are at least investment grade by the

                                In addition to the mandatory redemption
                                provisions, certain restrictive covenants and,
                                subject to a further condition, the security
                                interest ceasing to be effective from and after
                                the Covenant Modification Date (as each is
                                described above), on and after the Covenant
                                Modification Date certain events of default
                                that, from the Issue Date, were provided for by
                                the governing Indenture will terminate and
                                cease to be in effect. The terminated events of
                                default are based on (i) the failure to restore
                                a permit to an NJ Plant, which failed
                                restoration would have a Material Adverse
                                Effect (as defined herein) and (ii) a material
                                breach or misrepresentation by Cogen or certain
                                of its Subsidiaries under a material Project
                                Document (as herein defined) which would have a
                                Material Adverse Effect.
 
Cogen Covenants.............    The Indenture and the First Supplemental
                                Indenture also will contain certain covenants
                                of Cogen that, among other things, limit the
                                ability of Cogen and its Subsidiaries to create
                                liens or enter into sale and leaseback
                                transactions and limit the ability of Cogen to
                                engage in mergers and consolidations or
                                transfer all or substantially all of its
                                assets. The foregoing restrictions are subject
                                to a number of significant exceptions. See

                                Notes".
 
Use of Proceeds.............    The net proceeds from the issuance of the
                                Senior Notes will be used by Cogen to loan an
                                amount to Linden Ltd. for repayment of the
                                Bridge Loan (as defined herein), to retire
                                amounts payable to affiliates of Cogen, to pay
                                expenses related to the Formation Transactions

                                of the Common Stock, $.01 par value, of Cogen

                                any proceeds from the sale of shares of Common

                                Stock Offering. The closing of each of the Debt

                                Facility") not to exceed, at any one time
                                outstanding, an aggregate principal amount of
                                $300.0 million, which will be secured, on a

                                security interest granted by Cogen on the
                                Pledged Interest. The Revolving Credit Facility
                                will

                                scheduled to fund on or about the Issue Date,
                                with one scheduled to mature 364 days after its

          DESCRIPTION OF SENIOR NOTES AND CERTAIN OTHER INDEBTEDNESS
 
DESCRIPTION OF THE SENIOR NOTES
 
General
   
  The Senior Notes will be issued under an Indenture, dated as of           ,
1998 (as supplemented by the First Supplemental Indenture of even date
therewith and entered into by Cogen and the Trustee in connection therewith,
the "Indenture"), between Cogen and Chase Bank of Texas, National Association
(the "Trustee"). The Senior Notes offered hereby constitute three separate
series of senior secured notes limited to (i) $100.0 million aggregate
principal amount with respect to the 2005 Notes, (ii) $150.0 million aggregate
principal amount with respect to the 2010 Notes and (iii) $150.0 million
aggregate principal amount with respect to the 2018 Notes. The following
summary of certain provisions of the Indenture does not purport to be
complete, makes use of defined terms (some but not all of which are defined
herein) and is subject to, and qualified in its entirety by, all of the
provisions of the Indenture, which is incorporated herein by this reference
and which is available upon request to the Trustee.     
   
  Although the Company has no intention, at present, to issue any additional
debt securities under the Indenture, the Indenture does not limit the
aggregate principal amount of debt securities that can be issued thereunder
and provides that debt securities may be issued from time to time thereunder
in one or more series, each in an aggregate principal amount authorized by
Cogen prior to issuance. There is no requirement under the Indenture that
future issues of debt securities of Cogen be issued exclusively under the
Indenture, and Cogen will be free to employ other indentures or documentation,
containing provisions different from those included in the Indenture or
applicable to one or more issues of debt securities (including the Senior
Notes), in connection with future issues of such other debt securities;
provided that no future issuance of debt securities will have a lien senior to
the Senior Notes on the Pledged NJ Interests.     
 
  The 2005 Notes will mature on      , 2005 and will bear interest at   % per
annum, the 2010 Notes will mature on     , 2010 and will bear interest at   %
per annum, and the 2018 Notes will mature on     , 2018 and will bear interest
at   % per annum. Interest on each series of the Senior Notes will accrue from
          , 1998, and will be payable semi-annually on       and       (each
an "Interest Payment Date"), beginning     , 1999. Subject to certain
exceptions, the Indenture will provide for the payment of interest on the
Interest Payment Date only to Persons in whose names the Senior Notes are
registered on the Regular Record Date, which will be the [DATE] or [DATE]
(whether or not a Business Day), as the case may be, immediately preceding the
applicable Interest Payment Date. Interest will be computed on the basis of a
360-day year comprising twelve 30-day months.
 
Redemption Provisions
 
  Optional Redemption. Each series of the Senior Notes will be redeemable, at
the option of Cogen, at any time in whole or from time to time in part, upon
not less than 30 and not more than 60 days notice as provided in the
Indenture, on any date prior to its maturity (a "Redemption Date"), at a
redemption price (the "Redemption Price") equal to (i) 100% of the principal
amount of thereof plus (ii) accrued interest thereon to the Redemption Date
(subject to the right of holders of record on the relevant Regular Record Date
to receive interest due on an Interest Payment Date that is on or prior to the
Redemption Date) plus (iii) a Make Whole Premium, if any. In no event will the
Redemption Price ever be less than 100% of the principal amount of the Senior
Notes (or portion thereof) being redeemed plus accrued interest thereon to the
Redemption Date.
 
  The amount of the Make Whole Premium with respect to any Senior Note (or
portion thereof) to be redeemed will be equal to the excess, if any, of:
 
  (i) the sum of the present values, calculated as of the Redemption Date, of
  each remaining scheduled payment of principal and interest thereon
  (exclusive of interest accrued to such Redemption Date) discounted from the
  date such payment would have been payable, but for redemption, to such
  Redemption Date on a semiannual basis (assuming a 360-day year consisting
  of twelve 30-day months) at a discount
 
                                      20
<PAGE>
 
  rate equal to the Treasury Rate plus [  ] basis points with respect to the
  2005 Notes, [  ] basis points with respect to the 2010 Notes and [  ] basis
  points with respect to the 2018 Notes;
 
over
 
  (ii) the principal amount of the Senior Notes (or portion thereof) being
  redeemed.
 
  The applicable Treasury Rate will be determined as of the third Business Day
immediately preceding the applicable Redemption Date.
 
  Mandatory Redemption. Prior to the Covenant Modification Date (as defined
below), the Senior Notes are subject to mandatory redemption (at the
Redemption Price in the case of clauses (ii) and (iii) below) in the following
instances (each, a "Redemption Event"): (i) if an NJ Partnership or Cogen (on
behalf of an NJ Partnership) receives Net Loss Proceeds in excess of $50
million with respect to one or more Events of Loss affecting its NJ Plant and,
after reduction of that amount by the aggregate amount of all of such proceeds
used toward the restoration, repair, re-construction or replacement of its
affected NJ Plant, the remaining aggregate amount of Net Loss Proceeds (the
"Remaining Net Loss Proceeds") exceeds $50 million, unless after giving effect
to such Event of Loss and the use or contemplated use of the proceeds
therefrom as announced by Cogen, the Rating Agencies confirm the then current
ratings of the Senior Notes; (ii) if an NJ Partnership receives at any time
following the Issue Date an aggregate amount of Net Buyout Proceeds in excess
of $100 million from one or more Power Contract Buyouts related to its NJ
Plant, unless after giving effect to such buyout and the use or contemplated
use of the proceeds therefrom as announced by Cogen, the Rating Agencies
confirm the then current ratings on the Senior Notes; and (iii) if Cogen
sells, transfers, assigns or otherwise disposes of any NJ Partnership, or any
interest therein, or any NJ Partnership sells, transfers, assigns or otherwise
disposes of assets owned by such NJ Partnership, in one or more transactions,
whose Net Proceeds exceed $100 million (exclusive of Excluded Dispositions),
unless, after giving effect to such sale, transfer, assignment or other
disposition, the Rating Agencies confirm the then current ratings on the
Senior Notes.
 
  If a Redemption Event has occurred, the aggregate principal amount of the
Senior Notes to be redeemed will be equal to:
 
  (i) if the aggregate amount of such proceeds required (A) to repay
  indebtedness of an NJ Partnership and of its Managing General Partners, in
  each case, outstanding on the date hereof, and to fund accounts or
  otherwise be subject to restrictions on distributions by the lenders of
  such indebtedness, and (B) to be paid to partners or ventures, as
  applicable, of such NJ Partnership other than Cogen and its Subsidiaries
  (collectively, the "Required Payments") are less than or equal to, (1) $50
  million, in the case of Remaining Net Loss Proceeds, the Remaining Net Loss
  Proceeds minus $50 million and (2) $100 million, in the case of Net Buyout
  Proceeds or Net Proceeds, the Net Buyout Proceeds or Net Proceeds, as
  applicable, minus $100 million; or
 
  (ii) if the Required Payments are greater than $50 million in the case of
  Remaining Net Loss Proceeds or $100 million in the case of Net Buyout
  Proceeds or Net Proceeds, the Remaining Net Loss Proceeds, Net Buyout
  Proceeds or Net Proceeds, as applicable, minus the Required Payments, in
  each case if such amount is a positive number.
 
If the Senior Notes are redeemed pursuant to any of the foregoing provisions,
the Remaining Net Loss Proceeds, the Net Buyout Proceeds or Net Proceeds will
be applied (i) pari passu with any other senior secured debt of Cogen which
require redemption or repayment and (ii) pro rata among each of the series of
the Senior Notes.
 
  On and after the Covenant Modification Date, the Senior Notes will not be
subject to mandatory redemption.
 
  General Redemption Procedures. If less than all of the Senior Notes of a
series are to be redeemed, the Trustee shall select, in such manner as it
shall deem appropriate and fair, the particular Senior Notes of such
series or portions thereof to be redeemed, although no Senior Note of $1,000
in original principal amount or less shall be redeemed in part. Notice of
redemption shall be given by mail not less than 30 nor more than 60 days
 
                                      21
<PAGE>
 
prior to the date fixed for redemption to the holders of the Senior Notes (the
"Noteholders") of such series to be redeemed (which, as long as the Senior
Notes of such series are held in the book-entry only system, will be The
Depositary Trust Company ("DTC") (or its nominee) or a successor depositary
(the "Depositary")); provided, however, that the failure to duly give such
notice by mail, or any defect therein, shall not affect the validity of any
proceedings for the redemption of the Senior Notes of such series as to which
there shall have been no such failure or defect. On and after the date fixed
for redemption (unless Cogen shall default in the payment of the Senior Notes
of such series or portions thereof to be redeemed at the applicable Redemption
Price) interest on the Senior Notes of such series or the portions thereof so
called for redemption shall cease to accrue.
 
  No notice of redemption of the Senior Notes will be mailed during the
continuance of any Event of Default under the Indenture, except that (i) when
notice of redemption of any Senior Notes of any series has been mailed, Cogen
shall redeem such Senior Notes but only if funds sufficient for that purpose
have prior to the occurrence of such Event of Default been deposited with the
Trustee or a paying agent for such purpose, and (ii) notices of redemption of
all outstanding Senior Notes of all series may be given during the continuance
of an Event of Default under the Indenture.
 
  Any notice of redemption at the option of Cogen may state that such
redemption will be conditional upon receipt by the Trustee, on or prior to the
date fixed for such redemption, of money sufficient to pay the principal of,
and premium, if any, and interest, if any, on, such Senior Notes, and that if
such money has not been so received, such notice will be of no force and
effect and Cogen will not be required to redeem such Senior Notes.
 
  None of the 2005 Notes, the 2010 Notes, or the 2018 Notes have sinking fund
provisions, and the Senior Notes are not subject to redemption or repurchase
by Cogen at the option of the Holders.
 
Security
   
  The Senior Notes and the Revolving Credit Facility will be secured, on a
pari passu basis, by a security interest granted by Cogen in a portion of the
equity interests in Cogen Technologies Linden Limited Partner, Inc. ("Linden
LP Inc."), Cogen Technologies Linden GP, Inc. ("Linden GP Inc"), Cogen
Technologies Camden Limited Partner, Inc., Cogen Technologies Camden GP
Holdings, L.L.C. and Cogen Technologies Bayonne, Inc., each a direct, wholly-
owned Subsidiary of Cogen, which Subsidiaries own all of Cogen's equity
interests in the NJ Partnerships; provided however, at no time will such
security interest extend to or cover (directly or indirectly), and there shall
be excluded from such security interest, equity interests in such Subsidiaries
which would result in any of the following occurrences: (i) Robert McNair or
his wife or children failing to own and control, directly or indirectly, an
unencumbered beneficial interest of at least 8.2% in each of Linden Ltd. and
Linden Venture until September 15, 1999 and in each of Camden GPLP and Cogen
Camden until April 1, 2000, (ii) after September 15, 1999 in the case of each
of Linden Ltd. and Linden Venture and April 1, 2000 in the case of each of
Camden GPLP and Cogen Camden, Robert McNair or his wife or children or an
entity with a net worth equal to at least $100.0 million failing to own and
control, directly or indirectly, an unencumbered beneficial interest of at
least 8.2% in each of Linden Ltd. and Linden Venture and in each of Camden
GPLP and Cogen Camden, or (iii) the unencumbered beneficial equity interests
owned in NJ Inc. being less than at 50.1%. In no event, however, will such
security interest, directly or indirectly, encumber any of the NJ Partnerships
or any of the Managing General Partners, or any of the assets, rights or
properties of any of such Persons. Upon the satisfaction of the conditions
described in "--Conditions for Covenant Modifications", and without further
action or step taken by any Person or requirement of any nature satisfied,
such security interest will immediately and forever terminate and cease to be
operative; provided that, if on the Covenant Modification Date, any other pari
passu Indebtedness of Cogen is secured by any security interest on the Pledged
Interests, the Senior Notes will continue to be secured by the security
interest in the Pledged Interests (as described above) until such time as no
other pari passu Indebtedness has a security interest on the Pledged
Interests, in which case, the security interest in the Pledged Interests will
immediately and forever terminate (subject to any subsequent operation of the
provisions specified in "--Limitations on Liens").     
   
  Each of the equity interests in Linden LP Inc. and Linden GP Inc., which is
covered by the Pledged Interests, is a class of capital stock that entitles
the holders thereof to the distributions and dividends of Linden     
 
                                      22
<PAGE>
 
   
LP Inc. and Linden GP Inc., but do not entitle such holders to vote any equity
interests in Linden LP Inc. or Linden GP Inc., except as required by
applicable Delaware General Corporation Law. Each of the equity interests of
Linden LP Inc. and Linden GP Inc. which is entitled to vote is a separate
class of capital stock that is not covered by the Pledged Interests and will
be subject to a separate security interest that is not in favor of the
Noteholders; however, the holders of such equity interests, and the pledgee
thereof, will not be entitled to any dividends or distributions of Linden LP
Inc. or Linden GP Inc., respectively. As a result of this bifurcation of
interests in the equity interests of Linden LP Inc. and Linden GP Inc., the
Noteholders will not have any right to participate in any vote regarding the
management of Linden LP Inc. or Linden GP Inc., including on any issue to
foreclose on, or manage the activities of, the equity interests owned by those
entities in Linden Ltd., unless such vote is required by applicable law.
Currently, applicable Delaware General Corporation Law entitles the holder of
outstanding shares of a class of capital stock, whether or not entitled to
vote thereon by the related certificate of incorporation, to vote as a class
on any amendment to the certificate of incorporation that would, among other
things, alter or change the powers, preferences, or special rights of the
shares of such class so as to affect them adversely. All remaining equity
interests covered by the Pledged Interests entitle the holders thereof to all
rights incidental to equity ownership, including dividend, distributions and
voting rights.     
 
Ranking
   
  The Senior Notes will be senior secured obligations of Cogen and will rank
pari passu in right of payment with all other senior secured obligations of
Cogen, including Cogen's obligations under the Revolving Credit Facility and
senior in right of payment to all existing and future subordinated debt of
Cogen. A significant portion of Cogen's operations are conducted through its
directly and indirectly owned Subsidiaries, and therefore, Cogen is dependent
on the cash flow of its Subsidiaries to meet its debt obligations, including
its obligations under the Senior Notes. Although earnings from Cogen's
Subsidiaries may be provided to Cogen through distributions and payments on
intercompany indebtedness, certain outstanding indebtedness of Linden Ltd.,
Camden GPLP, Camden Cogen and NJ Venture may restrict, and certain agreements
in the partnership agreements of Camden Cogen and Linden Venture providing for
preferential distributions to Persons other than Cogen or any of its
Subsidiaries may limit, the payment of distributions and repayments of
intercompany indebtedness to Cogen. The claims of the Noteholders effectively
will be subordinated to the prior claims of secured creditors of Cogen which
hold liens in assets of Cogen other than the Pledged Interests and liens
created in favor of the Noteholders pursuant to the provisions of the covenant
set forth under the caption "--Certain Covenants--Limitation on Liens", claims
of creditors, including trade creditors, of the Subsidiaries of Cogen and
claims of holders of certain preferred equity interests in Linden Venture and
Camden Cogen. At June 30, 1998, after giving pro forma effect to the Debt
Offering, (i) Cogen would have no indebtedness which is secured by liens on
its assets other than the Pledged Interests, which assets may also secure, on
a pari passu basis, the Revolving Credit Facility, and (ii) the total current
and other liabilities and long-term debt of the Subsidiaries included in
Cogen's consolidated financial statements would have been approximately $234.2
million (not including $197.7 million with respect to the NJ Partnerships
which amount is not included in Cogen's financial statements under the equity
method of accounting).     
   
  During the period commencing with the Issue Date and until the Covenant
Modification Date, the Indenture will, subject to certain exceptions, restrict
the ability of Cogen and the NJ Partnerships, but no other Subsidiaries of
Cogen, to incur unsecured indebtedness pursuant to provisions that are
separately applicable to Cogen and the NJ Partnerships. See "--Certain
Covenants of Cogen and the NJ Partnerships--Permitted Indebtedness", "--
Certain Covenants of Cogen and the NJ Partnerships--Limitation on NJ
Partnership Debt" and "--Certain Covenants of Cogen and the NJ Partnerships--
Conditions for Covenant Modification". Further, the Indenture will restrict
the ability of Cogen and its Subsidiaries, before and after the Covenant
Modification date, to incur liens to secure indebtedness, except for specified
circumstances, which circumstances include the ability of a Subsidiary of
Cogen to encumber all or substantially all of its assets in connection with
its project financing. See "--Cogen Covenants--Limitation on Liens" and "--
Cogen Covenants--Limitation on Sale and Leaseback Transactions". The claims of
the Noteholders are effectively subordinated to unsecured Indebtedness
incurred by a Subsidiary of Cogen, and secured indebtedness incurred by Cogen
and any of its Subsidiaries, subject to     
 
                                      23
<PAGE>
 
   
the exceptions set forth in the covenants under the captions "--Cogen
Covenants--Limitation on Liens" and "--Cogen Covenants--Limitation on Sale and
Leaseback Transactions".     
 
Registration, Transfer and Exchange
 
  The Senior Notes of each series will initially be issued in the form of one
or more Global Notes, in registered form, without coupons in denominations of
$1,000 or an integral multiple thereof as described under "--Book-Entry
System". The Global Notes will be registered in the name of a nominee of DTC.
Except as set forth herein under "--Book-Entry, Delivery and Form", owners of
beneficial interests in a Global Note will not be entitled to have the Senior
Notes registered in their names, will not receive or be entitled to receive
physical delivery of any such Senior Note and will not be considered the
registered holder thereof under the Indenture.
 
  The Senior Notes of any series will be exchangeable for other Senior Notes
of the same series of any authorized denominations and of a like aggregate
principal amount and tenor.
 
  The Senior Notes may be presented for exchange or registration of transfer
(duly endorsed or accompanied by a duly executed written instrument of
transfer), at the office of the Trustee maintained in the Borough of
Manhattan, The City of New York, for such purpose with respect to any series
of the Senior Notes without service charge but upon payment of any taxes and
other governmental charges as described in the Indenture. Such transfer or
exchange will be effected upon Cogen and the Trustee being satisfied with the
documents of title and indemnity of the Person making the request.
 
  In the event of any redemption of the Senior Notes of any series, the
Trustee will not be required to exchange or register a transfer of any Senior
Notes of such series selected, called or being called for redemption except,
in the case of any Senior Note to be redeemed in part, the portion thereof not
to be so redeemed.
 
Book-Entry, Delivery and Form
 
  The Senior Notes of each series to be sold as set forth herein will be
issued in the form of a fully registered Global Note (the "Global Note"). The
Global Note for each series will be deposited on the date of the closing of
the sale of the Senior Notes offered hereby with, or on behalf of DTC and
registered in the name of its nominee (such nominee being referred to herein
as the "Global Note Holder") or will remain in the custody of the Trustee
pursuant to a FAST Balance Certificate Agreement or similar agreement between
the Depositary and the Trustee.
 
  Except as set forth below, each Global Note may be transferred, in whole and
not in part, only to another nominee of the Depositary or to a successor of
the Depositary or its nominee.
 
  DTC has advised Cogen and the Underwriters as follows: DTC is a limited
purpose trust company created to hold securities that its participating
organizations ("Participants") deposit with DTC and to facilitate the
clearance and settlement of securities transactions between Participants
through electronic book-entry changes to accounts of its Participants, thereby
eliminating the need for physical movement of certificates. "Participants"
include securities brokers and dealers (including the Underwriters), banks,
trust companies, clearing corporations and certain other organizations. Access
to DTC's book-entry system is also available to others, such as securities
brokers and dealers, banks and trust companies that clear through or maintain
custodial relationships with Participants, either directly or indirectly
("Indirect Participants"). Persons who are not Participants may beneficially
own securities held by DTC only through Participants or Indirect Participants.
 
  DTC has also advised that pursuant to procedures established by it (i) upon
the issuance by Cogen of the Senior Notes, DTC will credit the accounts of
Participants designated by the Underwriters with the principal amount of the
Senior Notes of each series purchased by the Underwriters and (ii) ownership
of beneficial interests in the Global Note of each series will be shown on,
and the transfer of that ownership will be effected only through, records
maintained by DTC (with respect to Participants' interests), the Participants
and the
 
                                      24
<PAGE>
 
Indirect Participants. The laws of some states require that certain Persons
take physical delivery in definitive form of securities which they own.
Consequently, the ability to transfer beneficial interests in the Global Note
is limited to such extent.
 
  All payments on the Global Note of each series registered in the name of
DTC's nominee will be made by Cogen through the Paying Agent to DTC's nominee
as the registered owner of the Global Note of each series. Under the terms of
the Indenture, Cogen and the Trustee will treat the Persons in whose names the
Senior Notes of each series are registered as the owners of such Senior Notes
for the purpose of receiving payment of principal of, and premium, if any, and
interest on, such Senior Notes and for all other purposes whatsoever.
Therefore, neither Cogen, the Trustee nor the Paying Agent has any direct
responsibility or liability for the payment of principal of, or premium, if
any, interest on, the Senior Notes to owners of beneficial interests in the
Global Note of each series. DTC has advised Cogen and the Trustee that its
current practice is, upon receipt of any payment of principal, premium, if
any, or interest, to credit immediately the accounts of the Participants with
payments in amounts proportionate to their respective holdings in principal
amount of beneficial interests in the Global Note as shown in the records of
DTC. Payments by Participants and Indirect Participants to owners of
beneficial interests in the Global Note of each series will be governed by
standing instructions and customary practices, as is the case with securities
held for the accounts of customers in bearer form or registered in "street
name" and will be the responsibility of such Participants or Indirect
Participants.
 
  Cogen will issue the Senior Notes of a series in definitive form in exchange
for the Global Note for such series if, and only if, either (i) DTC is at any
time unwilling or unable to continue as depositary and a successor depositary
is not appointed by Cogen within 90 days, (ii) an Event of Default has
occurred and is continuing and the Trustee has received a request from the
Depositary to issue the Senior Notes for such series in definitive form in
lieu of all or a portion of the Global Note of such series (in which case
Cogen shall execute within 30 days of such request, and the Trustee, upon
receipt of an Officers' Certificate, shall promptly authenticate and make
available for delivery the Senior Notes of such series in definitive form), or
(iii) Cogen determines not to have the Senior Notes represented by Global
Note. In any such instance, an owner of a beneficial interest in the Global
Note of each series will be entitled to have the Senior Notes of such series
equal in principal amount to such beneficial interest registered in its name
and will be entitled to physical delivery of such Senior Notes in physical
form. The Senior Notes so issued in definitive form will be issued in
denominations of $1,000 and whole multiples thereof and will be issued in
registered form only, without coupons.
 
  So long as the Global Note Holder is the registered owner of the Global
Notes, the Global Note Holder will be considered the sole Holder under the
Indenture of any Senior Notes evidenced by the Global Note. Beneficial owners
of the Senior Notes evidenced by the Global Note will not be considered the
owners or Holders thereof under the Indenture for any purpose, including with
respect to the giving of any directions, instructions or approvals to the
Trustee thereunder. Neither Cogen nor the Trustee will have any responsibility
or liability for any aspect of the records of DTC or any successor or for
maintaining, supervising or reviewing any records of DTC of any successor
relating to the Senior Notes.
 
Payment and Paying Agents
 
  Payments of principal of, and interest and premium, if any, on, the Senior
Notes issued in the form of Global Notes shall be made by wire transfer of
immediately available funds to the account specified by the registered holder
of such Global Note, which shall initially be a nominee of DTC. Interest on
the Senior Notes (other than interest at maturity) that are in the form of
certificated notes ("Certificated Notes") will be paid by check mailed to the
Person entitled thereto at such Person's address as it appears in the register
for the Senior Notes maintained
by the Trustee; however, a Noteholder of one or more series under the
Indenture in the aggregate principal amount of $2 million or more will be
entitled to receive payments of interest on such series by wire transfer of
immediately available funds to a bank within the continental United States if
appropriate wire transfer instructions have been received by the Trustee on or
prior to the applicable Regular Record Date. The principal of, and interest at
maturity and premium, if any, on, the Senior Notes in the form of Certificated
Notes will be payable in immediately available funds at the office of the
Trustee or at the authorized office of any paying agent.
 
                                      25
<PAGE>
 
  If and to the extent that Cogen fails to make timely payment of interest on
any Senior Note, that interest shall cease to be payable to the Persons who
were the holders of such Senior Notes at the applicable Regular Record Date,
and shall instead become payable to the holder of such Senior Note at the
close of business on a special record date established by the Trustee which
special record date shall be not more than 15 or fewer than 10 days prior to
the date of the proposed payment.
 
  All monies paid by Cogen to the Trustee for the payment of principal of,
interest or premium, if any, on, any Senior Note which remain unclaimed at the
end of two years after such principal, interest or premium shall have become
due and payable will be repaid to Cogen, subject to applicable abandoned
property laws, and the holder of such Senior Note will thereafter look only to
Cogen for payment thereof, subject to applicable limitations law.
 
  In any case where the date of maturity of the principal of, or any premium
or interest on, any Senior Note or the date fixed for redemption of any Senior
Note is not a Business Day, then payment of such principal or any premium or
interest need not be made on such date but may be made on the next succeeding
Business Day with the same force and effect as if made on the date of maturity
or the date fixed for redemption, and, in the case of timely payment thereof,
no interest shall accrue for the period from and after such interest payment
date or the date on which the principal or premium of the Senior Note is
stated to be payable to such next succeeding Business Day.
 
Certain Covenants of Cogen and the NJ Partnerships
 
  The First Supplemental Indenture will contain various covenants, including
the following:
   
  Permitted Indebtedness. Cogen will not create, incur, or suffer to exist any
Indebtedness, other than (i) the Senior Notes and other indebtedness under the
Indenture (excluding debt securities subsequently issued thereunder); (ii) in
an aggregate amount not to exceed $300 million at any one time outstanding,
(A) Indebtedness incurred pursuant to the Revolving Credit Facility and (B)
Letters of Credit Indebtedness; (iii) Indebtedness ranking pari passu in right
of payment with the Senior Notes, the Revolving Credit Facility and the Letter
of Credit Indebtedness, provided that at the time of the incurrence of such
Indebtedness either (A) Cogen certifies that, after giving effect to the
incurrence of such Indebtedness, the Coverage Ratio for (y) the four fiscal
quarters preceding the date of such incurrence and (z) the Projected Debt
Service Coverage Ratio for the four fiscal quarters succeeding such
incurrence, in each case is not less than 2.25:1.00 or (B) each of the Rating
Agencies confirm the then current ratings of the Senior Notes (after giving
effect to the incurrence of such Indebtedness); (iv) Subordinated
Indebtedness; and (v) Indebtedness incurred to refinance, renew, replace,
defease or refund, in whole or part, any Indebtedness specified in clauses (i)
through (iv) (inclusive) above and any Indebtedness incurred pursuant to this
clause (v).     
 
  Notwithstanding clauses (i) through (vii) of the definition of the term
"Indebtedness" or any provision of this covenant, the covenant under the
caption "--Certain Covenants of Cogen and the NJ Partnerships-- Limitation on
NJ Partnership Debt" or the Indenture, any Indebtedness will be deemed to have
been satisfied and discharged, and at all relevant times deemed to be neither
existing nor outstanding, for all purposes of such covenants and the Indenture
if there has been irrevocably deposited in trust for the benefit of the
holders of such Indebtedness, any combination of money or obligations issued
by or guaranteed by the full faith and credit of the United States of America
sufficient to pay all interest and principal, including applicable premium if
any, when due on such Indebtedness for the sole purpose of payment of such
Indebtedness.
 
  Limitation on NJ Partnerships Debt. The NJ Partnerships will not create,
incur or suffer to exist any Indebtedness other than (i) $[  ] of Indebtedness
outstanding on the Issue Date, (ii) Indebtedness in an aggregate amount not to
exceed $100 million, at any one time outstanding, for improvements and
expansions to any or all of the NJ Plants and (iii) other Indebtedness
required to satisfy any fiduciary responsibilities of the partners or
venturers, as applicable, of each of the NJ Partnerships (provided no such
fiduciary responsibilities shall be deemed to exist if all of the partnership
or venture interests of an NJ Partnership are owned directly or indirectly by
Cogen).

  Restricted Payments. Cogen may declare and pay dividends or pay or make any
other distributions on account of its Capital Stock or Subordinated
Indebtedness to Affiliates on a quarterly basis provided that (a) no Default
or Event of Default has occurred and is then continuing and (b) the amount of
such dividends or other distributions paid or made, as applicable, do not
exceed the sum of (i) 100% of Funds From Operations for the period commencing
on the Issue Date plus (ii) $50 million. Distributions of assets, other than
cash, in excess of $5 million with respect to any asset or group of related
assets, shall be valued by an Independent Investment Banker, or if less than
$5 million, at the fair market value of such assets as determined in good
faith by the Board of Directors of Cogen.
   
  Conditions for Covenant Modifications. On the day that (i) Cogen has a
portfolio comprising interests in at least eight power projects with no single
project contributing more than 25% or less than 5% of aggregate Cash
Distributions for each of the four quarters preceding such date of
determination and the four quarters succeeding such date of determination (as
projected by Cogen), as certified by both the Independent Engineer and Cogen's
Chief Financial Officer (with forecasts relating to merchant capacity
reflecting cash flows for such capacity over the previous four quarters) and
(ii) the then current ratings on the Senior Notes are at least investment
grade by the Rating Agencies (such day, the "Covenant Modification Date"),
then, without further action or step taken by any Person or requirement of any
nature being satisfied, (1) the covenants entitled "Permitted Indebtedness",
"Restricted Payments" and "Limitation on NJ Partnership Debt" (the "Additional
Covenants") will immediately and forever terminate and cease to be operative,
(2) if no other Indebtedness of Cogen is then secured by a security interest
in the Pledged Interests as described under the caption "--Security", then the
security interest in the Pledged Interests will immediately and forever
terminate and be deemed released (subject to any subsequent operation of the
provisions specified in "--Limitations on Liens"), (3) the Events of Default
and Defaults provided for in, and based upon, any occurrence provided for in
clause (vii) or (viii) under the caption "--Events of Default" will
immediately and forever terminate and cease to be operative and (4) the
mandatory redemptions provided for under the caption "--Mandatory Redemption"
will immediately and forever terminate and cease to be operative, and in each
case of the preceding clauses (1), (2), (3) and (4), such termination and
release and the inoperativeness of such covenants and provisions shall remain
and continue in effect for all times thereafter even if, among other things,
at a date subsequent to the Covenant Modification Date the conditions
specified in the preceding clauses (i) and (ii) cease to be in effect.     
 
Cogen Covenants
 
  The Indenture contains various additional covenants, including the
following:
 
  Limitation on Liens. So long as any Senior Notes are outstanding, Cogen may
not, and may not permit any Subsidiary to, create, incur, assume, or suffer to
exist any Indebtedness that is secured by any mortgage, security interest,
pledge or lien ("Lien") of or upon any Principal Operating Property, whether
owned on the Issue Date or thereafter acquired, without in any such case
effectively securing the Senior Notes (together with, if Cogen shall so
determine, any other Indebtedness of Cogen ranking equally with the Senior
Notes) equally and ratably with such Indebtedness (but only so long as such
Indebtedness is so secured).
   
  The foregoing restriction will not apply to: (i) the Pledged Interests; (ii)
any Liens existing on the Issue Date, including any Lien which would extend to
property acquired after the Issue Date pursuant to any agreement entered into
prior to the Issue Date, or any Lien created pursuant to an "after-acquired
property" clause or similar terms in existence on the Issue Date; (iii) Liens
on any property existing at the time of its acquisition (which Liens may also
extend to subsequent repairs, alterations, replacements and improvements to
such property); (iv) Liens on any property of a Person existing at the time
such Person is merged into, consolidated with, or otherwise acquired by, or
such Person disposes of its properties (or those of a division) as or
substantially as an entirety to, Cogen or any of its Subsidiaries, or the
assumption by Cogen or any of its Subsidiaries of obligations secured by any
Lien existing at the time of acquisition by Cogen or any of its Subsidiaries
of the property subject to such Lien and not incurred in connection with, or
in contemplation of, such merger, consolidation or acquisition; (v) Liens on
property to secure all or part of (A) the cost of acquisition,     
 
                                      27
<PAGE>
 
   
construction, development or repair, alteration, replacement or improvement of
property of a Person or to secure Indebtedness incurred then or thereafter to
provide funds for any such purpose or for reimbursement of funds previously
expended for any such purpose, provided such Liens are created or assumed
contemporaneously with, or within 12 months after, such acquisition or the
completion of substantial repair, replacement or alteration, construction,
development or substantial improvement, or the commencement of full operations
thereof, whichever shall be the later and such Liens are limited to the
property which is the subject of such acquisition, construction, development
or repair, alteration or improvement, or other property or rights of any
Subsidiary of Cogen or of Cogen related thereto or derivative therefrom as
required by the lender or lenders of such financing persons, including with
respect to any Subsidiary of Cogen, (y) Liens which extend to any subsequently
acquired property of such Subsidiary, or (z) any Lien created pursuant to an
"after-acquired property" clause or similar terms pursuant to financing
documentation governing the indebtedness secured by such Lien and (B) the
working capital facility, letters of credit or similar operating or support
capital and credit facilities of any Subsidiary of Cogen, which is incurred by
such Subsidiary in relation to its ownership, management or operation of any
Facility or its equity interest in any Person that owns, manages or operates
any Facility and which Liens are limited to the property of such Subsidiary
and Cogen's equity interest in such Subsidiary; (vi) Liens in favor of any
federal or State government or any department, agency or instrumentality or
political subdivision thereof, or for the benefit of holders of securities
issued by any such entity (or providers of credit enhancement with respect to
such securities), to secure any Indebtedness (including, without limitation,
obligations of Cogen with respect to industrial development, pollution control
or similar revenue bonds) incurred for the purpose of financing all or any
part of the purchase price or the cost of substantially repairing or altering,
constructing, developing or substantially improving any property of Cogen or
any of its Subsidiaries; (vii) any Lien arising by reason of any attachment,
judgment, decree or order of any governmental or court authority, so long as
(A) a performance bond in the amount of such Lien has been posted and (B) any
proceeding initiated to review such attachment, judgment, decree or order
shall not have been terminated or the period within which such proceeding may
be initiated shall not expire, or such attachment, judgment, decree or order
shall otherwise be effectively stayed; (viii) any statutory or governmental
Lien or Lien arising by operation of law, or any mechanics', repairmen's,
materialmen's, suppliers', carriers', landlords', warehousemen's or similar
Lien incurred in the ordinary course of business for which the underlying
obligation is not yet due, or if due, which is being contested in good faith
by appropriate proceedings and for which a bond in the amount of such Lien has
been posted; (ix) Liens of taxes and assessments which are (A) for the then
current year and not at the time delinquent, or (B) delinquent but the
validity of which is being contested at the time by Cogen or any of its
Subsidiaries in good faith and for which appropriate reserves have been
established in accordance with GAAP; (x) any Lien upon, or deposits of, cash
or cash equivalents in favor of any surety company, clerk of court or
otherwise for the purpose of obtaining indemnity or stay of judicial
proceedings; (xi) any Lien incurred in the ordinary course of business in
connection with workmen's compensation, unemployment insurance, temporary
disability, social security, retiree health or similar laws or regulations or
to secure obligations imposed by statute or governmental regulations and for
which appropriate reserves have been established; (xii) any Lien securing
Indebtedness of Cogen or any of its Subsidiaries, all or a portion of the net
proceeds of which are used, substantially concurrent with the funding thereof
(and for purposes of determining such "substantial concurrence", taking into
consideration, among other things, required notices to be given to holders of
outstanding securities under the Indenture (including the Senior Notes) in
connection with such refunding, refinancing or repurchase, and the required
corresponding durations thereof), to refinance, refund or repurchase all
outstanding securities under the Indenture (including the Senior Notes),
including the amount of all accrued interest thereon and reasonable fees and
expenses and premium, if any, incurred by Cogen or any such Subsidiaries in
connection therewith; (xiii) any Lien on any cash collateral or similar
account securing any Letter of Credit Indebtedness or any reimbursement
obligations of Cogen for any letters of credit or instruments serving a
similar function which are issued pursuant to the Revolving Credit Facility;
(xiv) the Lien in the Linden Class B Stock pursuant to the Linden Class B
Pledge; and (xv) any extension, renewal, refinancing, refunding or replacement
(or successive extensions, renewals, refinancing, refundings or replacements),
in whole or in part, of any Lien referred to in clauses (ii) through (xiv),
provided, however, that the principal amount of Indebtedness secured thereby
and not otherwise authorized by said clauses (ii) to (xiv), inclusive, shall
not exceed the principal amount of Indebtedness, plus any premium, fee and
related costs and expenses incurred or payable to third parties in connection
with any such extension, renewal, refinancing, refunding or replacement, so
secured at the time of such extension, renewal, refinancing, refunding or
replacement.     
 
                                      28
<PAGE>
 
   
  Notwithstanding the foregoing, under the Indenture, Cogen may, and may
permit any of its Subsidiaries to, create, incur, assume or suffer to exist,
any Lien upon any Principal Operating Property to secure any Indebtedness of
Cogen or any Person (other than the Senior Notes) that is not excepted by
clauses (i) through (xv) (inclusive) above without securing the Senior Notes,
provided that, after giving effect to the creation, incurrence or assumption
of such Lien and Indebtedness, and the application of proceeds of such
Indebtedness, if any, received by Cogen or any of its Subsidiaries as a result
thereof, the aggregate principal amount of all Indebtedness then outstanding
secured by such Lien and all similar Liens would not exceed the greater of
(A) $25 million and (B) 10% of Cogen's Tangible Net Worth.     
 
  Limitation on Consolidation, Merger and Sale or Disposition of Assets. Cogen
will not consolidate with or merge with or into any other Person or sell,
transfer or otherwise dispose of its properties as or substantially as an
entirety unless (i) the successor or transferee Person shall be a Person
organized and existing under the laws of the United States of America, any
State thereof, or the District of Columbia, (ii) the successor or transferee
Person assumes by supplemental indenture the due and punctual payment of the
principal of, and premium and interest on, all the Senior Notes and the
performance of every covenant of the Indenture to be performed or observed by
Cogen, (iii) immediately after giving effect to such transaction, no Event of
Default or Default shall have occurred and be continuing and (iv) Cogen shall
deliver to the Trustee an Officers' Certificate and an Opinion of Counsel,
each stating that the transaction and any such supplemental indenture comply
with the Indenture. Upon any such consolidation, merger, sale, transfer or
other disposition of the properties of Cogen as or substantially as an
entirety, the successor Person formed by such consolidation or with whom or
into which Cogen is merged or to which such sale, transfer or other
disposition is made shall succeed to, and be substituted for, and may exercise
every right and power of, Cogen under the Indenture with the same effect as if
such successor Person had been named as Cogen therein, and Cogen will be
released from all obligations under the Indenture.
 
  Limitation on Sale and Leaseback Transactions. So long as the Senior Notes
are outstanding, neither Cogen nor any of its Subsidiaries will enter into any
arrangement with any Person (other than Cogen or any of its wholly-owned
Subsidiaries), or to which any such Person is a party, providing for the
leasing to Cogen or any of its Subsidiaries for a period of more than three
years of any property or assets which has been or is to be sold or transferred
by Cogen or such Subsidiary to such Person or to any other Person (other than
Cogen or any of its wholly-owned Subsidiaries) to which funds in an aggregate
amount in excess of $5 million with respect to such leased property or assets,
or any series of related transactions including such leased property or
assets, have been or are to be advanced by such Person on the security of such
leased property or assets (a "Sale and Leaseback Transaction"), unless:
 
  (i) if the Covenant Modification Date has yet to occur, Cogen or, to the
  extent any of the following covenants are applicable to it, such Subsidiary
  would be entitled, pursuant to the provisions specified in "--Certain
  Covenants of Cogen and the NJ Partnerships--Permitted Indebtedness" and "
  Certain Covenants of Cogen and the NJ Partnerships--Limitation of NJ
  Partnerships Debt", to incur Indebtedness in a principal amount equal to or
  exceeding the Value of such Sale and Leaseback Transaction, secured by a
  Lien on the property to be leased pursuant to the provisions specified in
  "--Cogen Covenants--Limitation on Liens", without equally and ratably
  securing the Senior Notes;
 
  (ii) on and after the Covenant Modification Date, Cogen or such Subsidiary
  would be entitled to incur Indebtedness in a principal amount equal to or
  exceeding the Value of such Sale and Leaseback Transaction
  secured by a Lien on such property subject thereto pursuant to the
  provisions specified in "--Cogen Covenants--Limitation on Liens", without
  equally and ratably securing the Senior Notes; or
 
  (iii) Cogen, during or immediately after the expiration of six months
  following the effective date of such Sale and Leaseback Transaction
  (whether made by Cogen or any of its Subsidiaries), (i) applies to the
  voluntary prepayment, repayment, reduction, defeasance or retirement of
  Indebtedness of Cogen (including the Senior Notes) or of any of its
  Subsidiaries, in each case maturing by the terms thereof more than one year
  after the original incurrence thereof (hereinafter called "Funded Debt") an
  amount equal to the Value of such Sale and Leaseback Transaction, less an
  amount equal to the sum of (A) the principal amount of the
 
                                      29
<PAGE>
 
  Senior Notes delivered, within six months after the effective date of such
  arrangement, to the Trustee for retirement and cancellation and (B) the
  principal amount of other Funded Debt voluntarily prepaid, repaid, reduced,
  defeased or retired by Cogen or any of its Subsidiaries within such six
  month period, in each case excluding retirements of the Senior Notes and
  other Funded Debt as a result of conversions or pursuant to mandatory
  prepayment provisions or by payment at maturity;
 
provided that the foregoing restriction shall not apply to any portion of the
proceeds received from any Sale and Leaseback Transaction by a Subsidiary of
Cogen or Cogen and such proceeds are used by such Subsidiary or Cogen, as
applicable, to purchase additional assets for use by such Subsidiary; provided
that the obligations resulting from such Sale and Leaseback Transaction by a
Subsidiary of Cogen if Cogen shall have any obligations with respect thereto,
are non-recourse to Cogen other than Cogen's equity interest in such
Subsidiary as of the date of the transaction.
 
  Maintenance of Existence. Subject to the covenant above under "--Limitation
on Consolidation, Merger and Sale or Disposition of Assets", Cogen shall do or
cause to be done all things necessary to preserve and keep in full forces and
effect its corporate existence and so long as it has a controlling equity
interest in an NJ Partnership, the corporate or partnership existence (as the
case may be) of each NJ Partnership, in accordance with the respective
organizational documents (as the same may be amended and in effect from time
to time), and all rights and franchises of Cogen and so long as it has a
controlling equity interest in an NJ Partnership, each NJ Partnership;
provided, however, Cogen shall not be required to preserve such existence of
any NJ Partnership or keep in full force and effect any such right or
franchise of any such NJ Partnership if either (i) the maintenance thereof is
not consistent with its or any of its Subsidiaries' fiduciary obligations with
respect thereto (provided that no such fiduciary obligation shall be deemed to
exist if all of the partnership interests of an NJ Partnership are owned
directly or indirectly by Cogen) or (ii) the Board of Directors of Cogen shall
determine that (y) the preservation or maintenance thereof is no longer
desirable in the conduct of the business of Cogen and it Subsidiaries taken as
a whole, and (z) the loss thereof would not have a Material Adverse Effect.
 
  Nature of the Business. Cogen and its Subsidiaries shall engage only in a
Line of Business as well as any other activities or businesses that are a
reasonable extension, development or expansion of, or reasonably related to,
any Line of Business.
 
  Operation and Maintenance. Cogen shall, and shall cause each of its
Subsidiaries, if applicable, to, in all material respects, operate and
maintain each Facility in accordance with prudent industry operating and
maintenance practices generally accepted in the Line of Business and the
failure of which to operate and maintain, or cause to be operated and
maintained, would result in a Material Adverse Effect.
 
  Maintenance of Insurance. Cogen shall cause each of the NJ Partnerships to
maintain insurance policies covering such risks, in such amounts and with such
terms as are normally carried by similarly situated companies engaged in the
Line of Business in the United States.
 
  Taxes and Claims. Cogen will, and will cause each of its Subsidiaries to,
pay and discharge when due all taxes or claims imposed on it or on its income
or profits or on any of its properties, except such taxes as are being
contested in good faith in appropriate proceedings and for which appropriate
reserves have been established in accordance with GAAP or the failure of which
to pay and discharge would not have a Material Adverse Effect.
 
  Compliance with Law. Cogen will, and will cause each of its Subsidiaries to,
comply with all applicable laws, rules, regulations and orders of, and all
applicable restrictions imposed by, any Governmental Authority in respect of
the conduct of its business and the ownership of its properties, except to the
extent that any non-compliance therewith would not have a Material Adverse
Effect.
 
  Maintenance of Licenses and Approvals. Cogen will, and will cause each of
its Subsidiaries to seek and maintain such governmental licenses, permits and
approvals as are reasonably required to conduct the business
 
                                      30
<PAGE>
 
engaged in by Cogen or such Subsidiary and the failure of which to seek or
maintain would not have a Material Adverse Effect.
   
  Future Loan (or "Leveraged") Transactions. Subject to the limitations
discussed below, Cogen and its Subsidiaries could, in the future, enter into
certain transactions, including acquisitions, refinancings or other
recapitalizations, that could increase the amount of indebtedness outstanding
at such time or otherwise affect Cogen's capital structure or credit ratings.
Restrictions on the ability of Cogen and the NJ Partnerships to incur
additional Indebtedness, prior to the Covenant Modification Date, are
contained in the covenants described under the captions "--Certain Covenants
of Cogen and the NJ Partnerships--Permitted Indebtedness" and "--Certain
Covenants of Cogen and the NJ Partnerships--Limitation on NJ Partnerships
Debt". In addition, restrictions on the ability of Cogen and its Subsidiaries
to create or incur Liens to secure Indebtedness, before or after the Covenant
Modification Date, are contained in the covenants described under the captions
"--Cogen Covenants--Limitation on Liens" and "--Cogen Covenants--Limitation on
Sale and Leaseback Transactions". Such restrictions can only be waived with
the consent of the holders of a majority in principal amount of the Notes then
outstanding. Except for the limitations contained in such covenants, however,
the Indenture will not contain any covenants or provisions that may afford
holders of the Notes protection in the event of a future leveraged
transactions.     
 
Events of Default
 
  Each of the following shall constitute an Event of Default under the
Indenture: (i) default in the payment of principal of, and premium, if any,
on, any Senior Note when due and payable; (ii) default in the payment of
interest on any Senior Note when due which continues for 30 days; (iii)
default in the performance or breach of any other covenant or agreement of
Cogen in the Senior Notes or in the Indenture and the continuation thereof for
30 days after receipt of notice from the Trustee or the Noteholders of at
least 25% of the outstanding Senior Notes; (iv) bankruptcy, insolvency,
reorganization, assignment or receivership of any Project Owner; (v)
acceleration of any Indebtedness of Cogen in an amount in excess of $20
million; (vi) any final judgments(s) or decree(s) for the payment of money
(which are non-appealable or which remain unpaid or unstayed for a period of
90 or more consecutive days or as to which all rights to appeal have expired
or been exhausted) in excess of $20 million, excluding amounts covered by in-
force insurance for which the insurer has admitted liability, shall be entered
against Cogen; (vii) the revocation or withdrawal of a governmental license,
permit or other approval for the operation of an NJ Plant, if such revocation
or withdrawal would have a Material Adverse Effect and such license, permit or
approval is not restored within 45 days; and (viii) any Project Owner fails to
perform its material obligations under a material Project Document (within any
applicable grace or other extension period or without having received a waiver
or forbearance in respect thereto) or makes any material misrepresentations
thereunder and either such event results in a Material Adverse Effect.
Notwithstanding any provision herein to the contrary, on the Covenant
Modification Date each of clauses (vii) and (viii) will forever terminate and
cease to be operative as an Event of Default or a Default, or in any respect
as a basis for an Event of Default or a Default. See "--Conditions for
Covenant Modifications".
 
  If an Event of Default occurs and is continuing, the Trustee, upon the
written direction of holders of no less than 25% (for an Event of Default
specified in clauses (i) and (ii) above) or 51% (for any other Event of
Default) in aggregate principal amount of the Senior Notes, may accelerate the
Senior Notes of such series so the entire outstanding principal amount
thereof, accrued interest thereon, Make-Whole Premium (if any) and other
amounts payable with respect thereto shall become due and payable immediately,
provided that in the case of an Event of Default with respect to Cogen
described in clause (iv) above, the entire outstanding principal amount of,
the accrued interest on, and any other amounts payable with respect to, such
Senior Notes shall automatically become due and payable without direction from
any holders of the Senior Notes. At any time after an acceleration of the
Senior Notes has been declared but before a judgment or decree for the payment
of the principal amount of the Senior Notes has been obtained, if Cogen pays
or deposits with the Trustee a sum sufficient to pay all matured installments
of interest and the principal and any premium which has become due otherwise
than by acceleration and all Defaults shall have been cured or waived, then
such payment or deposit will cause an automatic rescission and annulment of
the acceleration of the Senior Notes.
 
                                      31
<PAGE>
 
  The Indenture will provide that the Trustee generally will be under no
obligation to exercise any of its rights or powers under the Indenture at the
request or direction of any of the Noteholders unless such holders have
offered to the Trustee reasonable security or indemnity. Subject to such
provisions for indemnity and certain other limitations contained in the
Indenture, the holders of a majority in principal amount of the outstanding
Senior Notes generally will have the right to direct the time, method and
place of conducting any proceeding for any remedy available to the Trustee, or
of exercising any trust or power conferred on the Trustee. The holders of a
majority in principal amount of the outstanding Senior Notes generally will
have the right to waive any past Default or Event of Default (other than a
payment default) on behalf of all Noteholders. The Indenture will provide that
no Noteholder may institute any action against Cogen under the Indenture
unless such holder previously shall have given to the Trustee written notice
of Default and continuance thereof and unless the holders of not less than a
majority in aggregate principal amount of the Senior Notes then outstanding
affected by such Event of Default shall have requested the Trustee to
institute such action and shall have offered the Trustee reasonable indemnity,
and the Trustee shall not have instituted such action within 60 days of such
request. Furthermore, no Noteholder will be entitled to institute any such
action if and to the extent that such action would disturb or prejudice the
rights of other Noteholders. Notwithstanding that the right of a Noteholder to
institute a proceeding with respect to the Indenture is subject to certain
conditions precedent, each holder of a Senior Note has the right, which is
absolute and unconditional, to receive payment of the principal of and
premium, if any, and interest, if any, on such Senior Note when due and to
institute suit for the enforcement of any such payment, and such rights may
not be impaired without the consent of such Noteholder. The Indenture will
provide that the Trustee, within 90 days after the occurrence of a Default
with respect to the Senior Notes, is required to give the holders of the
Senior Notes notice of any such Default known to the Trustee, unless cured or
waived, but, except in the case of default in the payment of principal of, or
premium, if any, or interest on, any Senior Notes, the Trustee may withhold
such notice if it determines in good faith that it is in the interest of such
holders to do so. Cogen is required to deliver to the Trustee following each
calendar quarter a certificate as to whether or not, to the knowledge of the
officers signing such certificate, Cogen is in compliance with the conditions
and covenants under the Indenture.
 
Modification
 
  Modification and amendment of the Indenture may be effected by Cogen and the
Trustee with the consent of the holders of a majority in principal amount of
the outstanding Senior Notes affected thereby, provided that no such
modification or amendment may, without the consent of the holder of each
outstanding Senior Note affected thereby, (i) change the maturity date of any
Note; (ii) reduce the rate (or change the method of calculation thereof) or
extend the time of payment of interest on any Note; (iii) reduce the principal
amount of, or premium payable on, any Note; (iv) change the coin or currency
of any payment of principal of, or any premium or interest on, any Note; (v)
change the date on which any Senior Note may be redeemed or repaid at the
option of the holder thereof or adversely affect the rights of a holder to
institute suit for the enforcement of any payment on or with respect to any
Note; or (vi) modify the foregoing requirements or reduce the percentage of
outstanding Senior Notes necessary to modify or amend the Indenture or to
waive any past Default to less than a majority. Modification and amendment of
the Indenture may be effected by Cogen and the Trustee without the consent of
the holders in certain cases, including (i) to add to the covenants of Cogen
for the benefit of the holders or to surrender a right conferred on Cogen in
the Indenture; (ii) to add security for the Senior Notes; (iii) to execute and
deliver such instruments and take such action and steps with respect to the
Covenant Modification Date, and the effects thereof, as referred to under the
caption "Conditions for Covenant Modifications"; (iv) to cure or otherwise
correct any ambiguities, omissions, defects or inconsistencies, which actions,
in each case, do not adversely affect the interests of the holders in any
material respect; (v) to provide for the assumption of the obligations of
Cogen under the Indenture upon the merger, consolidation or sale, transfer or
other disposition of all or substantially all of the properties of Cogen
permitted pursuant to the Indenture; (vi) to comply with any requirement in
order to effect or maintain the qualification of the Indenture under the Trust
Indenture Act of 1939; (vii) to make any other change that does not adversely
affect the holders of any outstanding Senior Notes in any material respect; or
(viii) issue additional series of securities under the Indenture.
 
  A supplemental indenture which changes or eliminates any covenant or other
provision of the Indenture (or any supplemental indenture) which has expressly
been included solely for the benefit of one or more series of
 
                                      32
<PAGE>
 
the Senior Notes, or which modifies the rights of the Noteholders of such
series with respect to such covenant or provision, will be deemed not to
affect the rights under the Indenture of the Noteholders of any other series.
 
Defeasance and Discharge; Covenant Defeasance
 
  The Indenture will provide that Cogen may satisfy and discharge, and will be
discharged from, any and all obligations in respect to the Senior Notes of any
series and the Indenture (except for certain obligations such as obligations
to register the transfer or exchange of the Senior Notes, replace stolen, lost
or mutilated Senior Notes, maintain paying agencies and hold moneys for
payment in trust) if, among other things, Cogen irrevocably deposits with the
Trustee, in trust for the benefit of holders of the Senior Notes, money or
certain United States government obligations, or any combination thereof,
which through the payment of interest thereon and principal thereof in
accordance with their terms will provide money in an amount sufficient,
without reinvestment, to make all payments of principal of, and any premium
and interest on, the Senior Notes on the dates such payments are due in
accordance with the terms of the Indenture and the Senior Notes; provided
that, unless all of such Senior Notes are to be due within one year of such
deposit by redemption or otherwise, Cogen shall also have delivered to the

recognize income, gain or loss for federal income tax purposes as a result of
such defeasance or discharge of the Indenture and that will be subject to
federal income tax on the same amount, in the same manner and at the same
times, as would have been the case if such defeasance or discharge had not
occurred. Thereafter, the Noteholders must look only to such deposit for
payment of the principal of, and interest and any premium on, the Senior
Notes.
 
  In addition, the Indenture will provide that Cogen may, with respect to the
Senior Notes of any series, terminate its obligations with respect to certain
restrictive covenants of the Indenture ("covenant defeasance"), in which event
certain Events of Default will no longer constitute Events of Default with

character and quality, and receipt by the Trustee of an Opinion of Counsel of
the scope, referred to in the immediately preceding paragraph; provided that
such Opinions of Counsel shall not be required to be based upon a ruling
(private or otherwise) from the Internal Revenue Service or a change in law or
regulation to that effect.
 
Resignation or Removal of Trustee
 
  The Trustee may resign at any time upon written notice to Cogen specifying
the day upon which the resignation is to take effect, and such resignation
will take effect immediately upon the later of the appointment of a successor
Trustee and such specified day.
 
  The Trustee may be removed at any time by an instrument or concurrent
instruments in writing filed with the Trustee and signed by the holders, or
their attorneys-in-fact, of at least a majority in principal amount of the
then outstanding Senior Notes of all series. In addition, so long as no Event
of Default or event which, with the giving of notice or lapse of time or both,
would become an Event of Default has occurred and is continuing, Cogen may
remove the Trustee upon notice to the holder of each Senior Note outstanding
and the Trustee and appointment of a successor Trustee.
 
Concerning the Trustee
 
  Chase Bank of Texas, National Association, will be the Trustee under the
Indenture. Cogen and one or more of its Affiliates maintain depository and
other normal banking relationships with Chase Bank of Texas, National
Association. The Chase Manhattan Bank, an affiliate of Chase Bank of Texas,

that Cogen's obligations to compensate and indemnify the Trustee and reimburse
the Trustee for expenses, disbursements and advances will constitute
indebtedness which will be secured by a Lien generally prior to that of the
Senior Notes upon all property and funds held or collected by the Trustee as
such.

H.15 (519) or successor publication) plus 0.55%, with interest payable
quarterly. The principal with respect to the working capital portion is due
September 1, 2007. All such borrowings are secured by Linden Ltd.'s
partnership interest in Linden Venture. Linden Ltd. cannot make further
borrowings under the Linden GP Term Loan Agreement. See "Existing Venture and
Plant Descriptions--Linden General Partner Term Loan".     
 
                                      40

  The Linden GP Term Loan Agreement contains certain restrictions that
significantly limit or prohibit, among other things, the ability of Linden
Ltd. to incur indebtedness, make payments of certain indebtedness, pay
distributions to its owners, make investments, engage in transactions with
affiliates, create liens, sell assets and engage in acquisitions, mergers and
consolidations.
 
  Pursuant to the terms of a security deposit agreement among Linden Venture,
Linden Ltd., the Owner Trust, as limited partner and as lender, and a
financial institution as security agent and escrow agent, Linden Venture has
agreed that a portion of Linden Venture's revenues will be deposited in, among
other accounts, a segregated deposit account for the debt service and ratio
requirements of the Linden GP Term Loan, which deposit is made prior to any
distributions of amounts to owners of Linden Venture, and a segregated account
for amounts to be distributed to its owners. See "Existing Venture and Plant
Descriptions--Linden Cash Distributions". Further pursuant to such security
deposit agreement, Linden Ltd. has pledged its rights in the preceding-
described accounts to secure the Linden GP Term Loans.
 
  The effect of the Owner Trust's prior right to Linden Venture Distributable
Cash and the depositary arrangement described in the immediately preceding
paragraph is that the Company's rights (and, consequently, the Company's
creditors' and shareholders' rights) to Linden Venture Distributable Cash and
the cash deposited in the accounts governed by the security deposit agreement
are subordinated to the Owner Trust's and the Linden Ltd. term lender's
respective rights therein. In addition, while there is no indebtedness on
Linden Venture's balance sheet, the Linden Venture partnership agreement
contains certain provisions that effectively restrict Linden Venture from,
among other things, entering into certain agreements or commitments, selling
or otherwise transferring assets, incurring indebtedness (other than defined
permitted indebtedness), creating or allowing any lien on its property (other
than defined permitted liens) and amending or modifying project documents.
   
  Camden Cogen. Pursuant to the Camden Cogen Term Loan Agreement, and as of
June 30, 1998, Camden Cogen had $87.5 million of outstanding non-recourse
project financing term indebtedness from GECC and a syndication of
international banks, which indebtedness is secured by the Camden Plant and the
other Camden Cogen assets, revenues of Camden Cogen, the general partnership
interest of Camden GPLP, and the general partnership interest in Camden GPLP
owned by Cogen Technologies Camden, Inc. ("Camden Inc."), the general partner
of Camden GPLP and a subsidiary of the Company. Of such outstanding
indebtedness, $63.9 million represents the Camden Tranche A Loan, which
matures May 2007 and accrues interest at the per annum rate of either (i) 3-
month LIBOR plus an increasing margin of 1.00 to 1.625% (1.25% for the period
November 3, 1998 to November 1, 2001) or (ii) if such loan is in default, the
Bank of Tokyo Trust prime rate (which has an increasing margin of .375% to
1.0%) plus 2.0% or the fed funds rate plus 2.0%, whichever is higher, with
principal and interest payable quarterly. Principal payments with respect to
the Camden Tranche A Loan increase each quarter by varying amounts ranging
from approximately 1.5% to approximately 5.5% of the prior quarter's payment
with the principal payment due November 1, 1998 being $1.2 million, and the
final principal payment being $2.5 million. Camden Cogen has entered into an
interest rate swap agreement with GECC which effectively fixes the interest
rate with respect to the Camden Tranche A Loan at 5.945%. The swap agreement
has a notional amount equal at all times to the outstanding principal balance
of the Camden Tranche A Loan. The remaining portion of this indebtedness,
$23.6 million, represents the Camden Tranche B Loan, which matures in May 2009
and accrues interest at the per annum rate of 11.4%, with interest and
principal payable quarterly. Principal payments with respect to the Camden
Tranche B Loan increase each quarter by varying amounts ranging from
approximately 1.6% to approximately 4.0% of the prior quarter's payment, with
the principal payment due November 1, 1998 being $0.2 million, and the final
principal payment being $1.4 million. Optional prepayments on the Camden
Tranche B Loan are subject to a yield maintenance premium.     
 
  The Camden Cogen Term Loan Agreement contains certain restrictions that
significantly limit or prohibit, among other things, the ability of Camden
Cogen or its general partner, Camden GPLP, to incur indebtedness, make
payments of certain indebtedness, pay distributions to its owners, make
investments, engage in transactions with affiliates, create liens, sell
assets, amend material contracts and engage in acquisitions, mergers and
consolidations. In addition, such loan agreement requires Camden Cogen to
establish and maintain security
 
                                      41
<PAGE>
 
deposit accounts with a financial institution into which its revenues are
deposited and from which reserve accounts are funded and maintained for
various obligations, including the repayment of the Camden Cogen Term Loans,
the Camden Cogen letter of credit facility and the Camden GP Term Loans. See
"Existing Venture and Plant Descriptions--Camden Cash Distributions".
   
  At June 30, 1998, a standby letter of credit issued by GECC for the account
of Camden Cogen was outstanding in the aggregate amount of $4.8 million, for
the purpose of securing certain of its reserve account obligations on the
Camden Tranche A Loan. No fee is payable by Camden Cogen for such outstanding
letter of credit, which expires in May 2007. Camden Cogen's reimbursement
obligations under this letter of credit are secured by the same collateral
that secures the Camden Cogen Term Loans.     
 
  Pursuant to the terms of Camden Cogen's partnership agreement, the limited
partner is entitled to receive distributions on a basis preferential to the
interest of Camden GPLP. See "Existing Venture and Plant Description--Camden
Cash Distributions".
   
  Pursuant to the Camden GP Term Loan Agreement between Camden GPLP and GECC,
and as of June 30, 1998, Camden GPLP is indebted to GECC in the principal
amount of $12.7 million, which indebtedness is secured by its general
partnership interest in Camden Cogen, the general partnership interest in
Camden GPLP of its general partner, Camden Inc., and a portion of Camden Cogen
revenues committed to a corresponding reserve account. This term indebtedness
matures May 2010. Interest on this term indebtedness accrues at either a fixed
rate or a floating rate. The fixed rate is a per annum rate based upon the 10-
year Treasury rate plus 5%, and the floating rate is a per annum rate of
either (i) Citibank prime plus 3% or (ii) LIBOR plus 4.25%. Interest accruing
at the prime rate or the fixed rate is payable monthly, and interest accruing
at the LIBOR rate is payable on the last day of a relevant interest period.
Principal payments are determined on a quarterly basis and made monthly in an
amount equal to one-third of the quarterly amount. The quarterly amount
increases each quarter by approximately 2.6% of the prior quarterly amount.
Principal payments for the quarter ended November 1, 1998 total $0.1 million,
and principal payments for the final quarterly period total $0.5 million.
Optional prepayments on portions of the indebtedness accruing interest at the
fixed rate are subject to the payment of a yield maintenance premium, and
optional prepayments on portions of the indebtedness accruing interest at a
floating rate which are made during the period from April 1996 to April 2000
are subject to the payment of a premium on the prepaid portion thereof
calculated at an annually decreasing percentage which begins at 4%. Camden
GPLP cannot make further borrowings under the Camden GP Term Loan Agreement
pursuant to which this term indebtedness was incurred.     
 
  The Camden GP Term Loan Agreement contains certain restrictions that
significantly limit or prohibit, among other things, the ability of the Camden
GPLP to incur indebtedness, make payments of certain indebtedness, pay
distributions to its owners, make investments, engage in transactions with
affiliates, create liens, sell assets and engage in acquisitions, mergers and
consolidations.
 
  The effect of the foregoing financing arrangements regarding Camden Cogen
and Camden GPLP is that the Company's rights (and, consequently, the Company's
creditors' and shareholders' rights) to Camden Cogen Distributable Cash and
the cash deposited in the above-described security deposit accounts are
subordinated to the rights of Camden Cogen's and Camden GPLP's lenders'
respective rights therein.
   
  NJ Venture. Pursuant to the Prudential Loan Agreement and as of June 30,
1998, NJ Venture had $68.8 million of outstanding, non-recourse term project
financing indebtedness from Prudential, which is secured by the Bayonne Plant
and other NJ Venture assets and all revenues of NJ Venture. This indebtedness
matures October 2008 and accrues interest at the per annum rate of 10.85%,
with accrued interest and principal payable quarterly. The Prudential Term
Loan is non-callable through September 2002, and thereafter may, at the option
of NJ Venture, be prepaid at a premium on the prepaid portion thereof
calculated at a decreasing percentage which commences at 10.85%.     
 
  The Prudential Loan Agreement contains certain restrictions that
significantly limit or prohibit, among other things, the ability of NJ Venture
to incur indebtedness, make payments of certain indebtedness, pay
distributions
 
                                      42
<PAGE>
 
to its owners, make investments, engage in transactions with affiliates,
create liens, sell assets and engage in acquisitions, mergers and
consolidations. In addition, the Prudential Loan Agreement requires NJ Venture
to create a debt service reserve fund from net cash flow if NJ Venture's
annual debt service coverage ratio, calculated each quarter using the previous
twelve months' financial information, falls below 1.50x. NJ Venture must
increase the reserve until funds held in such reserve plus the funds available
for debt service equal 1.50x the previous twelve months' debt service. Any
funds held in such reserve may be released as, and to the extent that, the
balance of funds retained in such reserve (if any) together with NJ Venture's
net cash flow cause NJ Venture's coverage ratio to exceed 1.50x. Such annual
debt service coverage ratio has not been below 1.50x, and as a result, NJ
Venture has not been required to fund the debt service reserve. At December
31, 1997, NJ Venture's debt service coverage ratio as calculated under the
Prudential Loan Agreement was 1.84x.
   
  Pursuant to the Equipment Loan Agreement and as of June 30, 1998, NJ Venture
is indebted to the Bayonne Equipment Lender in the principal amount of $0.2
million and an additional amount for accrued interest of $0.2 million. Such
outstanding principal amount and accrued interest thereon mature the later of
May 22, 1998 and the expiration of the IMTT Steam Sale Agreement. The
obligations under the Equipment Loan Agreement are secured by the equipment
purchased by NJ Venture in connection with such agreement, and the payment of
the interest that has accrued and continues to accrue on the remaining
principal balance is non recourse to NJ Venture, it being limited to the
security for the loan.     
   
  At June 30, 1998, NJ Venture had $1.5 million outstanding under the $5.0
million Revolving Facility with SBT, which was established by it for short
term working capital requirements and expires December 1998. Borrowings under
the Revolving Facility are payable at the expiration of the facility and
accrue interest at the per annum rate of 0.5% below SBT prime, with accrued
interest being payable monthly, and are secured by rights to payments from NJ
Venture power purchase agreements. NJ Venture pays a commitment fee of 1/4 of
1% on the average unused principal balance of the Revolving Facility. In
addition, at June 30, 1998, a standby letter of credit issued by the UBS for
the account of NJ Venture in the amount of $4.6 million was outstanding for
the purpose of securing certain obligations of NJ Venture to PSE&G pursuant to
a tracking account arrangement. See "Existing Venture and Plant Descriptions--
Bayonne Power Purchase Agreement--PSE&G". The letter of credit was procured
for NJ Venture by Financial Services. NJ Venture pays a quarterly fee on such
letter of credit calculated at 0.3% per annum on the face amount of the letter
of credit to the issuer thereof. Financial Services has the reimbursement
obligations to such issuer in the event any drawing is made on the letter of
credit. Pursuant to agreement between NJ Venture and Financial Services, NJ
Venture agrees to reimburse Financial Services for all fees and reimbursement
obligations incurred by Financial Services under the letter of credit, which
obligation of NJ Venture is unsecured. Such letter of credit expires May 1999.

                CERTAIN U.S. FEDERAL INCOME TAX CONSIDERATIONS
 
  The following is a general discussion of the principal United States federal
income tax consequences of the purchase, ownership and disposition of the
Senior Notes to initial purchasers thereof who are United States Holders (as
defined below) and the principal United States federal income and estate tax
consequences of the purchase, ownership and disposition of the Senior Notes to
initial purchasers who are Foreign Holders (as described below). This
discussion is based on currently existing provisions of the Code, Treasury
regulations promulgated thereunder, and administrative and judicial
interpretations thereof, all as in effect on the date hereof and all of which
are subject to change possibly with retroactive effect, or different
interpretations. This discussion does not address the tax consequences to
subsequent purchasers of Senior Notes and is limited to purchasers who hold
the Senior Notes as capital assets, within the meaning of section 1221 of the
Code. This discussion also does not address the tax consequences to Foreign
Holders that are subject to United States federal income tax on a net basis on
income realized with respect to a Senior Note because such income is
effectively connected with the conduct of a United States trade or business.
Such Foreign Holders are generally taxed in a similar manner to United States
Holders, but certain special rules do apply. Moreover, this discussion is for
general information only and does not address all of the tax consequences that
may be relevant to particular initial purchasers in light of their personal
circumstances or to certain types of initial purchasers (such as certain
financial institutions, insurance companies, tax-exempt entities, dealers in
securities or persons who have hedged the risk of owning a Senior Note) or the
effect of any applicable state, local or foriegn tax law.
 
  PROSPECTIVE PURCHASERS ARE URGED TO CONSULT THEIR OWN TAX ADVISORS AS TO THE
PARTICULAR TAX CONSEQUENCES TO THEM OF THE PURCHASE, OWNERSHIP AND DISPOSITION
OF THE SENIOR NOTES, INCLUDING THE APPLICABILITY OF ANY FEDERAL TAX LAWS OR
ANY STATE, LOCAL OR FOREIGN TAX LAWS, AND ANY CHANGES (OR PROPOSED CHANGES) IN
APPLICABLE TAX LAWS OR INTERPRETATIONS THEREOF.
 
  As used herein, the term "United States Holder" means a holder of a Senior
Note that is, for United States federal income tax purposes, (a) a citizen or
resident of the United States (including certain former citizens and former
long-term residents), (b) a corporation, partnership or other entity created
or organized in or under the laws of the United States or any political
subdivision thereof, (c) an estate, the income of which is subject to United
States federal income taxation regardless of source, or (iv) a trust subject
to the primary supervision of a court within the United States and the control
of one or more United States persons, as described in Section 7701(a)(30) of
the Code. A "Foreign Holder" is a holder who is not a United States Holder.
 
UNITED STATES FEDERAL INCOME TAXATION OF UNITED STATES HOLDERS
 
  Payment of Interest on the Senior Notes. Interest paid or payable on a
Senior Note will be taxable to a United States Holder as ordinary interest
income, generally at the time it is received or accrued, in accordance with
such holder's regular method of accounting for United States federal income
tax purposes.
 
  Sale, Exchange or Retirement of the Senior Notes. Upon the sale, exchange,
redemption, retirement at maturity or other disposition of a Senior Note, a
United States Holder generally will recognize taxable gain or loss equal to
the difference between the sum of cash plus the fair market value of all other
property received on such disposition (except to the extent such cash or
property is attributable to accrued but unpaid interest, which will be taxable
as ordinary income) and such United States Holder's adjusted tax basis in the
Senior Note. A United States Holder's adjusted tax basis in a Senior Note
generally will equal the cost of the Senior Note to such United States Holder,
less any principal payments received by such United States Holder.
 
  Gain or loss recognized on the disposition of a Senior Note generally will
be capital gain or loss and will be long-term capital gain or loss if, at the
time of such disposition, the United States Holder's holding period for the
Senior Note is more than one year. The deduction of capital losses is subject
to certain limitations. United States Holders of Senior Notes should consult
their tax advisors regarding the treatment of capital gains and losses.
 
                                      44
<PAGE>
 
  Backup Withholding and Information Reporting. Backup withholding and
information reporting requirements may apply to certain payments of principal,
premium, if any, and interest on a Senior Note, and to proceeds of the sale or
redemption of a Senior Note before maturity. The Company, its agent, a broker,
the Trustee or any paying agent, as the case may be, will be required to
withhold from any payment that is subject to backup withholding a tax equal to
31% of such payment if a United States Holder fails to furnish his, her or its
taxpayer identification number (social security or employer identification
number), certify that such number is correct, certify that such holder is not
subject to backup withholding or otherwise comply with the applicable
requirements of the backup withholding rules. Certain United States Holders,
including all corporations, are not subject to backup withholding and
information reporting requirements. Any amounts withheld under the backup
withholding rules from a payment to a United States Holder will be allowed as
a credit against such United States Holder's United States federal income tax
liability and may entitle the holder to a refund, provided that the required
information is furnished to the United States Internal Revenue Service
("IRS").
 
UNITED STATES FEDERAL INCOME TAXATION OF FOREIGN HOLDERS
 
  Payment of Interest on the Senior Notes. In general, payments of interest
received by a Foreign Holder will not be subject to a United States federal
withholding tax, provided that (i)(a) the Foreign Holder does not actually or
constructively own 10% or more of the total combined voting power of all
classes of stock of the Company entitled to vote, (b) the Foreign Holder is
not a controlled foreign corporation that is related to the Company actually
or constructively through stock ownership, and (c) either (I) the beneficial
owner of the Senior Note, under penalties of perjury, provides the Company or
its agent with such beneficial owner's name and address and certifies on IRS
Form W-8 (or a suitable substitute form) that it is not a United States person
or (II) a securities clearing organization, bank or other financial
institution that holds customers' securities in the ordinary course of its
trade or business (a "financial institution") holds the Senior Note and
provides a statement to the Company or its agent under penalties of perjury in
which it certifies that such an IRS Form W-8 (or a suitable substitute) has
been received by it from the beneficial owner of the Senior Notes or
qualifying intermediary and furnishes the Company or its agent a copy thereof
or (ii) the Foreign Holder is entitled to the benefits of an income tax treaty
under which interest on the Senior Notes is exempt from United States
withholding tax and the Foreign Holder or such Foreign Holder's agent provides
a properly executed IRS Form 1001 claiming the exemption. Payments of interest
not exempt from United States federal withholding tax as described above will
be subject to such withholding tax at the rate of 30% (subject to reduction
under an applicable income tax treaty).
 
  Sale, Exchange or Retirement of the Senior Notes. A Foreign Holder generally
will not be subject to United States federal income tax (and generally no tax
will be withheld) with respect to gain realized on the sale, exchange,
redemption, retirement at maturity or other disposition of a Senior Note
unless the Foreign Holder is an individual who is present in the United States
for a period or periods aggregating 183 or more days in the taxable year of
the disposition and, generally, either has a "tax home" or an "office or other
fixed place of business" in the United States.
 
  Backup Withholding and Information Reporting. Backup withholding and
information reporting requirements do not apply to payments of interest made
by the Company or a paying agent to Foreign Holders if the certification
described above under "--United States Federal Income Taxation of Foreign
Holders--Payment of Interest on the Senior Notes" is received, provided that
the payor does not have actual knowledge that the holder is a United States
Holder. If any payments of principal and interest are made to the beneficial
owner of a Senior Note by or through the foreign office of a foreign
custodian, foreign nominee or other foreign agent of such beneficial owner, or
if the foreign office of a foreign "broker" (as defined in applicable Treasury
regulations) pays the proceeds of the sale of a Senior Note to the seller
thereof, backup withholding and information reporting will not apply.
Information reporting requirements (but not backup withholding) will apply,
however, to a payment by a foreign office of a broker that is (i) a United
States person, (ii) a foreign person that derives 50% or more of its gross
income for certain periods from the conduct of a trade or business in the
United States, or (iii) a "controlled foreign corporation" (generally, a
foreign corporation controlled by certain United States shareholders) with
respect to the United States unless the broker has documentary evidence in its
records
 
                                      45
<PAGE>
 
that the holder is a Foreign Holder and certain other conditions are met or
the holder otherwise establishes an exemption. Payment by a United States
office of broker is subject to both backup withholding at a rate of 31% and
information reporting unless the holder certifies under penalties of perjury
that it is a Foreign Holder or otherwise establishes an exemption.
 
  Recently issued Treasury regulations modify certain of the certification
requirements described above. These modifications will become generally
effective for interest payments made after December 31, 1999. The Company or
its paying agent may request new withholding exemption forms from holders in
order to qualify for continued exemption from withholding under the Treasury
regulations when they become effective. For example, a Foreign Holder will be
required to provide a Form W-8 (or substitute form) to the withholding agent
on which such holder provides its name, address and taxpayer identification
number and states, under penalty of perjury, that the interest paid on a Note
and the gain on the sale, exchange or other disposition of a Note is not
effectively connected with such holder's United States trade or business in
order to obtain an exemption from withholding tax on payments made after
December 31, 1999.
 
FEDERAL ESTATE TAX
 
  Subject to applicable estate tax treaty provisions, Senior Notes held at the
time of death (or Senior Notes transferred before death but subject to certain
retained rights or powers) by an individual who at the time of death is a
Foreign Holder will not be included in such Foreign Holders' gross estate for
United State federal estate tax purposes provided that the individual does not
actually or constructively own 10% or more of the total combined voting power
of all classes of stock of the Company entitled to vote or hold the Senior
Notes in connection with a United States trade or business.

</TABLE>    
 
  The Underwriting Agreement provides that the obligations of the several
Underwriters to pay for and accept delivery of the Senior Notes offered hereby
are subject to the approval of certain legal matters by their counsel and to
certain other conditions. The Underwriters are obligated to take and pay for
all of the Senior Notes offered hereby if any are taken.
 
  The Underwriters propose to offer part of the Senior Notes directly to the
public at the price to public set forth on the cover page hereof and part to
certain dealers at a price that represents a concession not in excess of .  %
of the principal amount of the Senior Notes. Each Underwriter may allow, and
such dealers may re-allow, a concession to certain other dealers not in excess
of .  % of the principal amount of the Senior Notes. After the initial
offering of the Senior Notes, the offering price and other selling terms may
from time to time be varied by the Underwriters.
 
  The Senior Notes are a new issue of securities with no established trading
market. The Company has been advised by the Underwriters that they presently
intend to make a market in the Senior Notes, as permitted by applicable laws
and regulations. The Underwriters are not obligated, however, to make a market
in the Senior Notes and any such market making may be discontinued at any time
without notice at the sole discretion of the Underwriters. Accordingly, no
assurance can be given as to the liquidity of, or the existence of trading
markets for, the Senior Notes.
 
  In order to facilitate this Offering, the Underwriters may engage in
transactions that stabilize, maintain or otherwise affect the price of the
Senior Notes. Specifically, the Underwriters may overallot in connection with
this Offering, creating a short position in the Senior Notes for their own
account. In addition, to cover overallotments or to stabilize the price of the
Senior Notes, the Underwriters may bid for, and purchase, Senior Notes in the
open market. Finally, the underwriting syndicate may reclaim selling
concessions allowed to an underwriter or a dealer for distributing the Senior
Notes in this Offering, if the syndicate repurchases previously distributed
Senior Notes in transactions to cover syndicate short positions, in
stabilization transactions or otherwise. Any of these activities may stabilize
or maintain the market price of the Senior Notes above independent market
levels. The Underwriters are not required to engage in these activities, and
may end any of these activities at any time.
 
  The Company and the Underwriters have agreed to indemnify each other against
certain liabilities, including liabilities under the Securities Act.
   
  In conjunction with the Formation Transactions and immediately prior to the
closing of the Common Stock Offering, Morgan Stanley & Co. Incorporated will
loan $291.0 million to Linden Ltd. pursuant to the Bridge Loan. The Company
expects that it will advance as a loan to Linden Ltd. a portion of the
proceeds of the Debt Offering necessary for Linden Ltd to repay the Bridge
Loan in full. See "Capitalization". The Company has agreed to pay the fees and
expenses of Milbank, Tweed, Hadley & McCloy, counsel for the Underwriters in
connection with the Debt Offering. In addition, to facilitate the consummation
of the Formation Transactions, Morgan Stanley & Co. Incorporated will loan
$83.9 million to the McNair Interests and the Minority Interests which will be
repaid with a portion of the proceeds of the Common Stock Offering. From time
to time, Morgan Stanley & Co. Incorporated has provided and continues to
provide investment banking services to the Company.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
  Article Eighth of the Company's Certificate of Incorporation and Article X
of the Companys Bylaws provide for mandatory indemnification to at least the
extent specifically allowed by Section 145 of the General Corporation Law of
the State of Delaware (the GCL).
 
  Pursuant to Section 145 of the GCL, the Company generally has the power to
indemnify its current and former directors, officers, employees and agents
against expenses and liabilities incurred by them in connection with any suit
to which they are, or are threatened to be made, a party by reason of their
serving in such positions so long as they acted in good faith and in a manner
in which they reasonably believed to be, or not opposed to, the best interest
of the Company, and with respect to any criminal action, they had no
reasonable cause to believe their conduct was unlawful. With respect to suits
by or in the right of the Company, however, indemnification is generally
limited to attorneys' fees and other expenses and is not available if such
person is adjudged to be liable to the Registrant unless the court determines
that indemnification is appropriate. The statute expressly provides that the
power to indemnify authorized thereby is not exclusive of any rights granted
under any bylaw, agreement, vote of stockholders or disinterested directors,
or otherwise. The Company also has the power to purchase and maintain
insurance for such persons.
 
  The above discussion of the Company's Certificate of Incorporation and
Bylaws and Section 145 of the GCL is not intended to be exhaustive and is
qualified in its entirety by such document and statute.
 
  Directors and Officers are insured at the Company's expense, against certain
liabilities which might arise out of their employment and which are not
subject to indemnification under the Bylaws.
 
  Reference is made to the form of Underwriting Agreement, filed as Exhibit
1.1 hereto, which contains provisions for indemnification of the Company, its
directors, officers and any controlling persons by the Underwriters against
certain liabilities for information furnished by the Underwriters.
 
ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES.
 
  In connection with the organization of the Company, in May 1998 an aggregate
of 1,000 shares of Common Stock were issued to the McNair Interests and the
Minority Interests pursuant to Section 4(2) of the Securities Act of 1993, as
amended.

+ To be filed by amendment.
 
  As permitted by Item 601(b)(4) of Regulation S-K, the Company has not filed
with this Registration Statement certain instruments defining the rights of
holders of long-term debt of the Company, if any, because the total amount of
securities authorized under any of such instruments does not exceed 10% of the
total assets of the Company and its subsidiaries on a consolidated basis. The
Company agrees to furnish a copy of any such agreements to the Securities and
Exchange Commission upon request.
 
  (b) Financial Statement Schedules: None.
 
ITEM 17. UNDERTAKINGS.
 
  Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the Company
pursuant to the foregoing provisions, or otherwise, the Company has been
advised that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Securities Act
and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Company of expenses incurred or paid by a director, officer or controlling
person of the Company in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Company will, unless in
the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.
 
  The undersigned Company hereby undertakes to provide to the Underwriters at
the closing specified in the Underwriting Agreement certificates in such
denominations and registered in such names as required by the Underwriters to
permit prompt delivery to each purchaser.
 
  The undersigned Company hereby undertakes that:
 
  (1) For purposes of determining any liability under the Securities Act, the
      information omitted from the form of prospectus filed as a part of this
      Registration Statement in reliance upon Rule 430A and contained in a
      form of prospectus filed by the Company pursuant to Rule 424(b)(1) or
      (4) or 497(h) under the Securities Act shall be deemed to be a part of
      this Registration Statement as of the time it was declared effective.
 
  (2) For the purpose of determining any liability under the Securities Act,
      each post-effective amendment that contains a form of prospectus shall
      be deemed to be a new registration statement relating to the securities
      offered therein, and the offering of such securities at that time shall
      be deemed to be the initial bona fide offering thereof.
