  The issue price of the  % Senior Discount Notes due 2004 (the "Notes") being
offered hereby (the "Offering") by California Energy Company, Inc. (the
"Company") will be $  per $1,000 principal amount at maturity (the "Issue
Price") ( % of the principal amount at maturity). The Notes will be offered at
a substantial discount from their principal amount and will provide gross
proceeds of approximately $400,000,000 to the Company. The Notes will mature on
January 15, 2004. The Issue Price of each Note represents a yield to maturity
of  % (computed on a semi-annual bond equivalent basis) calculated from     ,
1994. Cash interest will not accrue on the Notes prior to January 15, 1997.
Commencing July 15, 1997, cash interest on the Notes will be payable on January
15 and July 15 of each year at a rate of  % per annum. See "Description of the
Notes" and "Certain Federal Income Tax Considerations."     
   
  The Notes will be redeemable, at the option of the Company, at any time, in
whole or in part, on or after January 15, 1999, at the redemption prices set
forth herein, plus accrued and unpaid interest, if any, to the date of
redemption. See "Description of the Notes--Optional Redemption." In addition,
in the event of a Change of Control (as defined), each holder of the Notes (a
"Holder") will have the right to require the Company to repurchase all or any
part of such Holder's Notes at a repurchase price equal to 101% of the Accreted
Value (as defined) thereof, plus accrued and unpaid interest, if any, to the
date of repurchase. See "Description of the Notes--Certain Covenants--Purchase
of Notes Upon a Change of Control."     
   
  The Notes will be senior unsecured obligations of the Company ranking pari
passu in right of payment of principal and interest with all other existing and
future senior unsecured obligations of the Company and will rank senior to all
other existing and future subordinated debt of the Company. The provisions of
the indenture pursuant to which the Notes will be issued will permit the
Company's subsidiaries, and certain joint ventures in which the Company will
own a significant interest, to incur substantial indebtedness which would be
effectively senior to the Notes.

                               PROSPECTUS SUMMARY
 
  The following summary is qualified in its entirety by, and should be read in
conjunction with, the more detailed information and financial statements,
including the notes thereto, appearing elsewhere in this Prospectus. Certain
capitalized terms used but not defined in this summary are used herein as
defined elsewhere in this Prospectus.
 
                                  THE COMPANY
   
  California Energy Company, Inc. (the "Company"), together with its
subsidiaries, is primarily engaged in the exploration for and development of
geothermal resources and the development, ownership and operation of
environmentally responsible independent power production facilities worldwide
utilizing geothermal resources or other energy sources, such as hydroelectric,
natural gas, oil and coal. The Company was an early participant in the domestic
independent power market and is now one of the largest geothermal power
producers in the United States. The Company is also actively pursuing
opportunities in the international independent power market. In the year ended
December 31, 1993, the Company had revenues of $149.3 million, net income of
$47.2 million, and as of that date, cash and investments at the Company level
of $127.8 million. Peter Kiewit Sons', Inc. ("Kiewit") is a 36.6% stockholder
(on a fully-diluted basis) in the Company and a participant in certain of the
Company's international private power projects.     
 
  Through its subsidiaries, the Company currently has significant ownership
interests in, and operates, four geothermal facilities that are qualified
facilities under the Public Utility Regulatory Policies Act of 1978 ("PURPA"),
which requires electric utilities to purchase electricity from qualified
independent power producers.
 
                                THE COSO PROJECT
   
  Three of the Company's geothermal facilities, located together at the Naval
Weapons Center at China Lake, California (collectively, the "Coso Project"),
have an aggregate generating capacity of approximately 240 megawatts ("MW").
The Company is the managing general partner, operator and owner of an
approximately 50% interest in the Coso Project, which currently constitutes the
Company's primary source of revenues. Electricity generated by the Coso Project
is sold pursuant to three long-term "Standard Offer No. 4" contracts (the "SO4
Agreements") to Southern California Edison Company ("SCE"). In 1993, the Coso
Project achieved record MW production results and received the maximum level of
capacity and capacity bonus payments under the S04 Agreements.     
 
            OTHER DOMESTIC OPERATIONS AND DEVELOPMENT OPPORTUNITIES
   
  The Company also owns and operates a 10 MW geothermal power plant located at
Desert Peak, Nevada, which is a qualified facility that sells power to Sierra
Pacific Power Company, and operates and owns a 70% interest in a geothermal
steam field at Roosevelt Hot Springs, Utah, which supplies 25 MW of geothermal
steam to Utah Power & Light Company under a 30-year steam sales contract.
Pursuant to a memorandum of understanding, the Company has commenced early
stage site work on a proposed 30 MW geothermal project at Newberry, Oregon (the
"Newberry Project"), which is expected to be completed in early 1997 and to be
wholly owned and operated by the Company.     
   
  Domestically, the Company plans to focus on developing and operating
geothermal power projects, an area in which the Company believes it has a
competitive advantage due to its geotechnical and project management expertise
and extensive geothermal leaseholdings. The Company intends to continue to
pursue geothermal opportunities in the Pacific Northwest where it has extensive
geothermal leaseholdings. In addition, the Company has diversified into other
environmentally responsible sources of power generation. The Company is
currently constructing a 50 MW natural gas fired cogeneration project in Yuma,
Arizona (the "Yuma Project"), which is expected to be wholly owned by the
Company and to sell electricity to San Diego Gas & Electric Company ("SDG&E")
under a 30-year power sales contract. The Company anticipates that this project
will be completed by mid-year 1994. The Company expects future diversification
through the selective acquisition of partially developed or existing power
generating projects and intends to maintain a significant equity interest in,
and to operate, the projects which it develops or acquires.

              INTERNATIONAL PROJECTS AND DEVELOPMENT OPPORTUNITIES
   
  The Company presently believes that the international independent power
market holds the majority of new opportunities for financially attractive
private power development in the next several years. The Company is actively
pursuing selected opportunities in nations where power demand is high and the
Company's geothermal resource development and operating experience, project
development expertise and strategic relationships are expected to provide it
with a competitive advantage. The Company believes that the opportunities to
successfully develop, construct, finance, own and operate international power
projects are increasing as several countries have initiated the privatization
of their power generation capacity and have solicited bids from foreign
developers to purchase existing generating facilities or to develop new
capacity. Some of these countries, such as the Philippines and Indonesia, also
have extensive geothermal resources.     
   
  The Company has recently entered into international joint venture agreements
with Kiewit and Distral S.A. ("Distral"), two firms with significant power
plant construction experience, in an effort to augment and accelerate the
Company's capabilities in foreign energy markets. Joint venture activities with
Distral will be conducted in South America, Central America and the Caribbean
and joint venture activities with Kiewit will be conducted in Asia, in
particular the Philippines and Indonesia, and in other regions not covered by
the Distral joint venture agreement. See "Business--International Projects and
Development Opportunities--International Joint Venture Agreements." To better
position itself to pursue international project development opportunities in
the Asian market, the Company recently established an office in Singapore to
oversee its activities in that region, including the Philippines and Indonesia.
    
THE PHILIPPINES
   
  The Company has obtained "take-or-pay" power sales contracts for two
geothermal power projects in the Philippines aggregating approximately 300 MW
in capacity. The Upper Mahiao Project, a 120 MW geothermal facility with an
estimated total project cost of approximately $226 million, is expected to be
constructed on the island of Leyte and will be over 95% owned and operated by
the Company. A syndicate of international banks is expected to provide an
approximately $170 million project finance construction loan for the project.
The Company expects that a portion of the proceeds of the Offering will be used
to provide all or part of its approximately $56 million equity commitment to
such project. The Export-Import Bank of the United States ("ExIm Bank") is
expected to provide the term loan that would be used to refinance the
construction loan for this project, as well as political risk insurance to the
syndicate of commercial banks for the construction loan. The Company intends to
arrange for similar insurance on its equity investment through the Overseas
Private Investment Corporation ("OPIC") or from other governmental agencies or
commercial sources. The Company expects that both the construction and term
loan agreements for the Upper Mahiao Project will be executed in April 1994 and
that the notice to proceed will be issued promptly thereafter under the
construction contract, which was executed in January 1994. Commercial operation
of this project is presently scheduled for mid-year 1996.     
   
  The Mahanagdong Project, a proposed 180 MW geothermal project with an
anticipated total project cost of approximately $310 million, is expected to be
operated by the Company and owned 45% by the Company, 45% by Kiewit and up to
10% by another industrial company. The Company intends to use a portion of the
proceeds of the Offering to fund all or part of its approximately $40 million
equity investment to the Mahanagdong Project, and to obtain political risk
insurance on its investment similar to that for the Upper Mahiao Project. The
Company is in the process of arranging construction financing for this project
from a syndicate of international banks on terms similar to those of the Upper
Mahiao construction loan. Such construction financing documentation is expected
to be executed by the end of the second quarter of 1994. The Company may use a
portion of the proceeds of the Offering to fund all or part of the
approximately $225 million in construction costs for the Project. The
construction financing is expected to close in mid-year 1994, with commercial
operation presently scheduled for mid-year 1997. See "Business--International
Projects and Development Opportunities--The Philippines."

INDONESIA
 
  The Company has been awarded the geothermal development rights to three
geothermal fields in Indonesia at Dieng, Patuha and Lampung/South Sumatra, the
initial phases of which could aggregate an additional generating capacity of
500 MW. The Company is currently negotiating power sales contracts for these
projects in Indonesia and, should such negotiations be successful and such
projects proceed, the Company intends to utilize a portion of the proceeds of
the Offering to fund equity investments and/or construction loans to these
projects. See "Business--International Projects and Development Opportunities--
Indonesia."
 
                                USE OF PROCEEDS
   
  The Company intends to use the net proceeds from the Offering (i) to fund
equity investments in, and the construction costs of, geothermal power projects
presently planned in the Philippines and Indonesia, (ii) to fund equity
investments in, and loans to, other potential international and domestic
private power projects and related facilities, (iii) for corporate or project
acquisitions permitted under the Indenture governing the Notes and (iv) for
general corporate purposes. As project loans are repaid, the Company may use
the proceeds again for any of such permitted uses. See "Use of Proceeds."

Ranking.....................     
                              The Notes will be senior unsecured obligations of
                              the Company ranking pari passu in right of
                              payment of principal and interest with all other
                              existing and future senior unsecured obligations
                              of the Company. The Company is a holding company
                              that derives substantially all of its income from
                              its operating subsidiaries and joint venture
                              projects. The Indenture does not limit the amount
                              of Non-Recourse Debt (as defined) which may be
                              incurred by the Company or at the subsidiary or
                              project level. Accordingly, the Notes will
                              effectively be subordinated to any secured Non-
                              Recourse Debt of the Company and to debt at the
                              project or subsidiary level. The Notes will rank
                              senior to all other existing and future
                              subordinated indebtedness of the Company. As of

                              December 31, 1993, on a pro forma basis, after
                              giving effect to the completion of this Offering
                              and the Company's planned defeasance of its 12%

                              (the "Senior Notes"), the Company's total
                              consolidated indebtedness (excluding deferred
                              income and redeemable preferred stock), would
                              have been $746.9 million, its total consolidated
                              assets would have been $1,077.0 million and its
                              stockholders' equity would have been $208.2
                              million.     
 
Original Issue Discount.....  The Notes will be issued with "original issue
                              discount" for federal income tax purposes. Thus,
                              although cash interest will not accrue on the
                              Notes prior to January 15, 1997, and there will
                              be no periodic payments of interest on the Notes
                              prior to July 15, 1997, original issue discount
                              (that is, the difference between the stated
                              redemption price at maturity and the issue price)
                              will accrue from the issue date of the Notes to
                              January 15, 1997 and will be includable as
                              interest income periodically in a Holder's gross
                              income for federal income tax purposes in advance
                              of receipt of the cash payments to which the
                              income is attributable. See "Certain Federal
                              Income Tax Considerations."

                              The Indenture governing the Notes contains

                              Affiliates (as defined), to enter into new lines
                              of business, to make certain investments, to
                              merge or consolidate with any other person or to

    Plants commenced commercial operation in February 1989 and January 1990,
    respectively. The Desert Peak facility and the Roosevelt Hot Springs field
    were acquired in March and January 1991, respectively.     
   
(2) The refinancing of the Coso joint ventures' project financing debt resulted
    in an extraordinary item in 1992 in the amount of $5.0 million, after the
    tax effect of $1.5 million.     
(3) On January 1, 1993, the Company adopted Statement of Financial Accounting
    Standard No. 109, "Accounting for Income Taxes," which resulted in a
    cumulative adjustment to net income of $4.1 million in 1993.
(4) The number of shares outstanding is calculated by using the treasury stock
    method.
   
(5) For information concerning the calculation of the ratio of earnings to
    fixed charges, see Note 5 to "Selected Historical Consolidated Financial
    and Operating Data--Statement of Operations Data."     
   
(6) "Consolidated EBITDA" and "Consolidated Fixed Charges" are calculated in
    accordance with the respective definitions of such terms in the Indenture
    and set forth herein under "Description of the Notes--Certain Definitions."
    The Company has included information concerning EBITDA herein because the
    concept is used in the financial covenants in the Indenture under which the
    Notes will be issued. EBITDA is presented here not as a measure of
    operating results, but rather as a measure of the Company's ability to
    service debt. EBITDA should not be construed as an alternative either (i)
    to operating income (determined in accordance with generally accepted
    accounting principles) or (ii) to cash flows from operating activities
    (determined in accordance with generally accepted accounting principles).
    In 1989, 1990 and 1991, the calculation of EBITDA was negatively affected
    by restrictions on cash balances imposed relating to the filing of
    mechanics' liens against, and related construction litigation involving,
    the Coso Project. Such restrictions were removed as part of the refinancing
    of the Coso Project in 1992 and subsequent settlement of such litigation.
    See Note 5 of Notes to the Consolidated Financial Statements.     
   
(7) As adjusted to give effect to the net proceeds of the Offering and the
    transaction described in Note 8, before deducting certain expenses payable
    by the Company in connection with the Offering estimated at $500,000. See
    "Use of Proceeds."     
   
(8) Simultaneously with the Offering, the Company intends to use approximately
    $39.0 million of its existing cash balances to defease and provide for the
    repayment of the entire aggregate principal amount of the Senior Notes
    outstanding.

                           INVESTMENT CONSIDERATIONS
 
  In addition to the other information contained in this Prospectus and the
documents incorporated herein by reference, prospective investors should
consider the factors set forth below prior to deciding whether to invest in the
Notes offered hereby.
 
DEVELOPMENT UNCERTAINTY
 
  The Company is actively seeking to develop, construct, own and operate new
power projects utilizing geothermal and other technologies, both domestically
and internationally, the completion of any of which is subject to substantial
risk. Development can require the Company to expend significant sums for
preliminary engineering, permitting, legal and other expenses in preparation
for competitive bids which the Company may not win or before it can be
determined whether a project is feasible, economically attractive or capable of
being financed. Successful development is contingent upon, among other things,
negotiation of construction, fuel supply and power sales contracts with other
project participants on terms satisfactory to the Company, and receipt of
required governmental permits and consents. Further, there can be no assurance
that the Company will obtain access to the substantial debt and equity capital
required to develop and construct electric power projects or to refinance
projects for which the Company has provided initial construction financing from
the proceeds of the Notes. See "Business--International Projects and
Development Opportunities--Funding for International Projects." The Company's
future growth is dependent, in large part, upon the demand for significant
amounts of additional electrical generating capacity and the Company's ability
to obtain contracts to supply portions of this capacity. There can be no
assurance that development efforts on any particular project, or the Company's
efforts generally, will be successful. See "Business--The Independent Power
Production Market."
 
DEVELOPMENT UNCERTAINTY OUTSIDE THE UNITED STATES
   
  The Company believes that the international independent power market holds
the majority of new opportunities for financially attractive private power
development in the next several years. The financing and development of
projects outside the United States entails significant political and financial
risks (including, without limitation, uncertainties associated with first time
privatization efforts in the countries involved, currency exchange rate
fluctuations, currency repatriation restrictions, political instability, civil
unrest and expropriation) and other structuring issues that have the potential
to cause substantial delays or material impairment of value to the project
being developed, which the Company may not be fully capable of insuring
against. The uncertainty of the legal environment in certain foreign countries
in which the Company may develop or acquire projects could make it more
difficult for the Company to enforce its rights under agreements relating to
such projects. In addition, the laws and regulations of certain countries may
limit the ability of the Company to hold a majority interest in some of the
projects that it may develop or acquire. The Company's international projects
may, in certain cases, be terminated by the government. See "Business--The
Independent Power Production Market" and "--International Projects and
Development Opportunities."     
 
HOLDING COMPANY STRUCTURE; NOTES ARE UNSECURED OBLIGATIONS
   
  The Company is a holding company which derives substantially all of its
operating income from its subsidiaries' ownership interests in the Coso Project
and through other project subsidiaries. The Company expects that its future
development efforts will be similarly structured to involve operating
subsidiaries, joint ventures and partnerships. The Company intends to loan or
contribute a substantial portion of the net proceeds from the sale of the Notes
to certain of its subsidiaries and joint ventures. See "Use of Proceeds."     
 
  The Company will be the sole obligor with respect to the Notes, and the Notes
will not be obligations of, or guaranteed by, any of the Company's subsidiaries
or joint ventures, whose assets will be used to secure future project level
debt. The Notes are not secured by any assets of the Company and the Company
must rely upon dividends and other payments from its subsidiaries, partnerships
and joint ventures to generate the funds necessary to meet its obligations,
including the payment of principal, interest and premium, if any, on
 
                                       11
<PAGE>
 
   
the Notes. The availability of distributions from the Coso Project is subject
to the satisfaction of various covenants and conditions contained in the Coso
joint ventures' refinancing documents. Furthermore, the Company is structuring
Philippine and Indonesian project financing arrangements containing, and
anticipates that future project level financings will contain, certain
conditions and similar restrictions on the distribution of cash flow to the
Company. See "Description of the Notes--Ranking" and "Business--The Coso
Project--Non-Recourse Coso Project Financing."     
 
HIGH LEVERAGE; ADDITIONAL DEBT PERMITTED AT SUBSIDIARY OR PROJECT LEVEL;
PRIORITY OF PROJECT DEBT
   
  After giving effect to the Offering, the Company will be highly leveraged. As
of December 31, 1993, the Company's total consolidated indebtedness was $382.6
million (excluding deferred income and redeemable preferred stock), its total
consolidated assets were $716.0 million and its stockholders' equity was $211.5
million. At such date, on a pro forma basis, after giving effect to the
completion of this Offering and the Company's planned defeasance of its Senior
Notes, the Company's total consolidated indebtedness (excluding deferred income
and redeemable preferred stock) would have been $746.9 million, its total
consolidated assets would have been $1,077.0 million and its stockholders'
equity would have been $208.2 million. See "Capitalization" and "Selected
Historical Consolidated Financial and Operating Data."     
   
  The Indenture does not limit the amount of Non-Recourse Debt which may be
incurred by the Company or at the subsidiary or project level. See "Description
of the Notes--Certain Covenants--Limitation on Subsidiary Debt." As a result,
the Notes are effectively subordinated to any secured Non-Recourse Debt of the
Company and to indebtedness and other obligations of the Company's subsidiaries
and the partnerships and joint ventures in which the Company has direct or
indirect interests. Claims of creditors of the Company's subsidiaries or joint
ventures, including trade creditors, will generally have priority as to the
assets of such subsidiaries or joint ventures over the claims of the Company
and the holders of the Company's indebtedness, including the Notes, except to
the extent that the Company may itself be a creditor with recognized claims
against such subsidiary or joint venture. In such case, the Company's claims
would still be subordinate to any security interests in the assets of such
subsidiary or joint venture and any indebtedness of such subsidiary or joint
venture senior to the claims of the Company. The Company intends to loan a
substantial portion of the net proceeds from the sale of the Notes to certain
of its subsidiaries and joint ventures. See "Use of Proceeds" and "Business--
International Projects and Development Opportunities--Funding for International
Projects." In addition, the Indenture limits, but does not prohibit, the
incurrence of additional indebtedness by the Company which may be subordinated
to the Notes or which may rank pari passu with the Notes. See "Description of
the Notes--Certain Covenants--Limitation on Debt."     
 
ENVIRONMENTAL AND OTHER REGULATIONS
   
  The Company's activities are subject to complex and stringent environmental
and other regulations. The construction and operation of power plants require
numerous permits, approvals and certificates from appropriate U.S. and foreign
federal, state and local governmental agencies as well as compliance with
environmental protection legislation and other regulations. While the Company
believes that it has obtained the requisite approvals for its existing
operations and that its business is operated in accordance with applicable law,
it remains subject to a varied and complex body of regulations that both public
officials and private individuals may seek to enforce. There can be no
assurance that existing regulations will not be revised or that new regulations
will not be adopted or become applicable to the Company which could have an
adverse impact on its operations. In addition, regulatory compliance for the
construction of new facilities is a costly and time consuming process and
intricate and rapidly changing environmental regulations may require major
expenditures for permitting and create the risk of expensive delays or material
impairment of project value if projects cannot function as planned due to
changing regulatory requirements or local opposition. See "Business--The Coso
Project--Regulatory and Environmental Matters."     
 
EXPLORATION, DEVELOPMENT AND OPERATION UNCERTAINTIES OF GEOTHERMAL ENERGY
RESOURCES
 
  Geothermal exploration, development and operations are subject to
uncertainties similar to those typically associated with oil and gas
exploration and development, including dry holes and uncontrolled releases.
Because of the geological complexities of geothermal reservoirs, the geographic
area and sustainable
 
                                       12
<PAGE>
 
output of a geothermal reservoir can only be estimated and cannot be
definitively established. There is, accordingly, a risk of an unexpected
decline in the capacity of geothermal wells, and a risk of geothermal
reservoirs not being sufficient for sustained generation of the electrical
power capacity desired. See "Business--Geothermal Energy."
 
CONSIDERATIONS RELATING TO THE COSO PROJECT
 
  The Coso Project currently constitutes the Company's primary source of
revenues. The following factors should be considered in connection with these
facilities:
   
 DEPENDENCE ON A SINGLE UTILITY CUSTOMER     
   
  Electricity generated by the three facilities (which facilities are sometimes
referred to as the "Navy I Project," the "BLM Project" and the "Navy II
Project") owned by the Coso Project joint ventures (referred to herein as the
"Navy I Joint Venture," the "BLM Joint Venture" and the "Navy II Joint
Venture," and collectively, the "Coso Joint Ventures") is sold pursuant to
three long-term SO4 Agreements to SCE. Each Coso Joint Venture currently relies
on its SO4 Agreement with SCE to generate 100.0% of its operating revenues. The
payments under these agreements have constituted 100.0% of the operating
revenues of the Coso Joint Ventures since their inception, are expected to
continue to do so for the term of the Notes, and, together, constituted
approximately 94.0% of the operating revenues of the Company in 1993. Any
material failure of SCE or any one of the Coso Joint Ventures to fulfill its
contractual obligations under any of the SO4 Agreements could have a material
adverse effect on the cash flow available to the Company from the Coso Joint
Ventures. See "Business--The Coso Project--Certain Material Contracts" and "--
Non-Recourse Coso Project Financing."     
   
 IMPACT OF AVOIDED COST PRICING     
   
  Under the SO4 Agreement with each Coso Joint Venture, SCE pays a fixed price
which escalates at an average annual rate of approximately 7.0% per year for
the remainder of the initial ten-year period under each SO4 Agreement, which
period continues until August 1997 for the Navy I Project, March 1999 for the
BLM Project and January 2000 for the Navy II Project. After the fixed price
period expires, while the basis for the capacity and capacity bonus payments
under the SO4 Agreements remains the same, the energy payments adjust to SCE's
then prevailing "Avoided Cost" (as determined by the California Public
Utilities Commission), which at present is substantially lower than the current
energy payments under the SO4 Agreements. The Company cannot predict the likely
level of Avoided Cost energy prices at the expiration of the fixed price
period. See "Business--The Coso Project--Certain Material Contracts."     
   
 GOVERNMENT'S RIGHT TO TERMINATE CONTRACTS     
   
  As is typical for any government agency which contracts for products or
services, the United States Department of the Navy (the "Navy") has the right
to terminate the lease of lands used by the Coso Joint Ventures under
circumstances that include the convenience of the Navy. In the event of
termination, the Navy is obligated to pay the Coso Joint Ventures owning the
Navy I Project and the Navy II Project an aggregate maximum amount of
approximately $352.5 million. Such payment would not take into consideration
the loss of anticipated future profits. With respect to the Company's
properties which are leased from the United States Bureau of Land Management
(the "BLM"), including the BLM Project, the BLM has the right to terminate its
leases if the leaseholder fails to comply with any of the provisions of such
leases, subject to the notice and hearing requirements and the right to cure
provided in the Geothermal Steam Act of 1970. However, if the leased premises
contain a well capable of steam production in commercial quantities, such
leases may be terminated only by judicial proceedings. At the present time, the
property leased by the Company from the BLM, on which the BLM Project is
situated, contains a well which is producing steam in commercial quantities.
See "Business--The Coso Project--Certain Material Contracts."     
 
SEISMIC DISTURBANCES; ADEQUACY OF INSURANCE
 
  Areas in the United States in which the Company is exploring for geothermal
resources are subject to frequent low-level seismic disturbances, and more
significant seismic disturbances are possible. Non-U.S. geothermal areas of
interest to the Company have been subject to even higher level seismic
disturbances.
 
                                       13
<PAGE>
 
   
While the Company's existing power generating systems are built to withstand
relatively significant levels of seismic disturbance, and the Company seeks
appropriate insurance protection, geothermal power production poses unusual
risks of seismic activity, and there can be no assurance that earthquake,
property damage or business interruption insurance will be adequate to cover
all potential losses sustained in the event of serious seismic disturbances or
that such insurance will be available on commercially reasonable terms. See
"Business--The Coso Project--Insurance."     
 
COMPETITION
 
  In recent years, the domestic power production industry has been
characterized by strong and increasing competition in an effort to obtain new
power sales agreements, which has contributed to a reduction in prices offered
by utilities. In this regard, many utilities often engage in "competitive bid"
solicitation to satisfy new capacity demands. See "Business--The Independent
Power Production Market." Many of the Company's competitors have more extensive
and more diversified developmental or operating experience (including
international experience) and greater financial resources than the Company. In
the domestic market, the Energy Policy Act of 1992 is expected to increase
competition.
 
ORIGINAL ISSUE DISCOUNT; EFFECT ON THE HOLDERS OF THE NOTES AND THE COMPANY
   
  The Notes will be issued at a substantial discount from their principal
amount at maturity. Consequently, purchasers of the Notes should be aware that,
although cash interest will not accrue on the Notes prior to January 15, 1997,
and there will be no periodic payments of cash interest on the Notes prior to
July 15, 1997, original issue discount (that is, the difference between the
stated redemption price at maturity and the issue price of the Notes) will
accrue from the issue date of the Notes and will be includable as interest
income periodically (including for periods ending prior to January 15, 1997) in
a Holder's gross income for U.S. federal income tax purposes in advance of
receipt of the cash payments to which the income is attributable. See "Certain
Federal Income Tax Considerations" for a more detailed discussion of the
federal income tax consequences to the Holders regarding the purchase,
ownership and disposition of the Notes. Further, the Notes may be subject to
the high yield discount obligation rules, in which case the Company would not
be able to deduct the original issue discount attributable to the Notes until
paid in cash or property. As explained in, and subject to, the discussion under
"Certain Federal Income Tax Considerations--Certain Federal Income Tax
Considerations to the Company and to Corporate Holders," the Notes will be
subject to these rules if their yield to maturity equals or exceeds a Treasury-
based interest rate in effect for the month of their issuance plus five
percentage points. For long-term debt instruments with an average life of more
than 9 years issued in March 1994, such Treasury-based interest rate plus five
percentage points is 11.28% compounded semi-annually. If these high yield
discount rules apply, the Company's after tax cash flow may be less than if
such original issue discount were deductible when accrued. In addition, if a
bankruptcy case were to be commenced by or against the Company under the U.S.
Bankruptcy Code after the issuance of the Notes, the claim of a Holder with
respect to the principal amount thereof may be limited to an amount equal to
the sum of (i) the initial offering price and (ii) that portion of the original
issue discount that is not deemed to constitute "unmatured interest" for
purposes of the U.S. Bankruptcy Code. Any original issue discount that was not
amortized as of any such bankruptcy filing would constitute "unmatured
interest."     
 
NO PRIOR PUBLIC MARKET; POSSIBLE VOLATILITY OF NOTE PRICE
   
  Prior to the Offering, there has been no public market for the Notes. The
Company intends to make application to the New York Stock Exchange to have the
Notes listed for trading thereon, but there can be no assurance that the Notes
will be accepted for listing on such exchange or, if listed, that an active
trading market for the Notes will develop or be sustained. If such a market
were to develop, the Notes could trade at prices that may be higher or lower
than their initial offering price depending upon many factors, including
prevailing interest rates, the Company's operating results and the markets for
similar securities. The Underwriters have advised the Company that they
currently intend to make a market in the Notes; however, they are not obliged
to do so and any market making may be discontinued at any time. Historically
the market for non-investment grade debt has demonstrated substantial
volatility in the prices of securities similar to the Notes. There can be no
assurance that the future market for the Notes will not be subject to similar
volatility.

<PAGE>
 
                                USE OF PROCEEDS
 
  The Company intends to use the net proceeds from the Offering (i) to fund
equity investments in, and the construction costs of, geothermal power projects
presently planned in the Philippines and Indonesia, (ii) to fund equity
investments in, and loans to, other potential international and domestic
private power projects and related facilities, (iii) for corporate or project
acquisitions permitted under the Indenture and (iv) for general corporate
purposes. As project loans are repaid, the Company may use the proceeds again
for any of such permitted uses. See "Business--International Projects and
Development Opportunities--Funding for International Projects."
   
  The Upper Mahiao and Mahanagdong Projects are expected to require equity
commitments by the Company of approximately $56 million and approximately $40
million, respectively. The Company may apply up to approximately $225 million
to provide interim construction debt financing for the Mahanagdong Project. All
or part of these costs may be funded by the proceeds of this Offering. See
"Business--International Projects and Development Opportunities--The
Philippines."     
 
  The Company evaluates from time to time various acquisition opportunities.
The Company may elect to pursue one or more of these opportunities, but has no
present intention to effect any material acquisition.
   
  Pending application, the Company will invest the net proceeds from the sale
of the Notes in Cash Equivalents. See "Description of the Notes--Certain
Definitions."

(2) The refinancing of the Coso Project resulted in an extraordinary item in
    1992 in the amount of $5.0 million, after the tax effect of $1.5 million.
        
(3) On January 1, 1993, the Company adopted Statement of Financial Accounting
    Standard No. 109, "Accounting for Income Taxes," which resulted in a
    cumulative adjustment to net income of $4.1 million in 1993.
(4) The number of shares outstanding is calculated by using the treasury stock
    method.
(5) For purposes of computing historical ratios of earnings to fixed charges,
    earnings are divided by fixed charges. "Earnings" represent the aggregate
    of (a) the pre-tax income of the Company, including its proportionate
    share of the pre-tax income of the Coso Joint Ventures (see Notes 1 and 2
    of Notes to the Consolidated Financial Statements), (b) fixed charges,
    less capitalized interest and (c) the amortization of previously
    capitalized interest. "Fixed charges" represent interest (whether expensed
    or capitalized), amortization of deferred financing and bank fees, and the
    portion of rentals considered to be representative of the interest factor
    (one-third of lease payments).
   
(6) "Consolidated EBITDA" and "Consolidated Fixed Charges" are calculated in
    accordance with the respective definitions of such terms in the Indenture
    and set forth herein under "Description of the Notes--Certain
    Definitions." The Company has included information concerning EBITDA
    herein because the concept is used in the financial covenants in the
    Indenture under which the Notes will be issued. EBITDA is presented here
    not as a measure of operating results, but rather as a measure of the
    Company's ability to service debt. EBITDA should not be construed as an
    alternative either (i) to operating income (determined in accordance with
    generally accepted accounting principles) or (ii) to cash flows from
    operating activities (determined in accordance with generally accepted
    accounting principles). In 1989, 1990 and 1991, the calculation of EBITDA
    was negatively affected by restrictions on cash balances imposed relating
    to the filing of mechanics' liens against, and related construction
    litigation involving, the Coso Project. Such restrictions were removed as
    part of the refinancing of the Coso Project in 1992 and subsequent
    settlement of such litigation. See Note 5 of Notes to the Consolidated
    Financial Statements.

               MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                      CONDITION AND RESULTS OF OPERATIONS
 
  The following is management's discussion and analysis of certain significant
factors which have affected the Company's financial condition and results of
operations during the periods included in the accompanying statements of
operations.
 
GENERAL
   
  For purposes of consistency in financial presentation, the plants comprising
the Coso Project (including the Navy I, Navy II and BLM Plants) capacity
factors are based upon a capacity amount of 88 gross MW ("GMW")/80 net MW
("NMW") for each plant. The Navy I and Navy II Plants each consist of a set of
three turbines located at a plant site. The BLM Plant consists of two turbines
at one site ("BLM East") and one turbine at another site ("BLM West"). In April
1990, the Company completed a retrofit of the two turbines at BLM East and in
July 1990 completed associated retrofitting of the cooling towers to increase
the aggregate installed capacity of the BLM Plant to 88 GMW/80 NMW, effective
July 2, 1990. Each plant possesses an operating margin which periodically
allows for production in excess of the amount listed above. However, through
1990, the Navy I, Navy II and BLM Plant capacity amounts were restricted by the
then existing PURPA 80 NMW cap. With the lifting of the PURPA 80 NMW cap in
1991, utilization of this operating margin can, at times, produce plant
capacity factors in excess of 100%. Utilization of this operating margin is
based upon a variety of factors and can be expected to vary throughout the year
under normal operating conditions.     
 
RESULTS OF OPERATIONS
 
 Three Years Ended December 31, 1993, 1992 and 1991
   
  Sales of electricity and steam increased to $132.1 million in the year ended
December 31, 1993 from $117.3 million in the year ended December 31, 1992, a
12.5% increase. This improvement was primarily due to a 9.1% increase in the
Coso Project's electric kWh sales to 2,186.7 million kWh from 2,004.0 million
kWh, and an increased price per kWh in accordance with the SO4 Agreements. The
increase in Coso Project kWh sales was primarily due to the completion of new
production wells. The increase in sales of electricity and steam in 1992 to
$117.3 million from $106.2 million in 1991 was primarily due to increasing
electric kWh sales by 6.0% to 2,004.0 million kWh from 1,890.4 million kWh
largely as a result of the drilling of additional production wells and the
aforementioned increase in price per kWh pursuant to the SO4 Agreements.     
 
  The following operating data includes the full capacity and electricity
production of the Coso Project only:

  The overall Coso plant capacity factor was 108.8% in the fourth quarter of
1993 compared to 109.1%, 100.9% and 97.1% for the third, second and first
quarters of 1993, respectively. The Navy I Plant capacity factor was 111.2% in
1993, compared to 99.8% and 98.5% in 1992 and 1991, respectively. The Navy II
Plant capacity factor was 102.6% in 1993, compared to 98.1% and 99.9% in 1992
and 1991, respectively. The BLM Plant capacity factor was 98.1% in 1993
compared to 87.2% and 71.4% in 1992 and 1991, respectively. The BLM Plant, Navy
I Plant and the Navy II Plant were overhauled in conjunction with scheduled
warranty inspections in 1993, 1992 and 1991 respectively, resulting in a
temporary reduction of the plant capacity factor of 3% in the specified year.
    
  Electric sale price per kWh for the Coso Project varies seasonally in
accordance with the rate schedule included in the SO4 Agreements. The price
consists of an energy payment based on the annualized contracted rate of 10.11
cents per kWh in 1993, 9.23 cents per kWh in 1992, and 8.58 cents per kWh in
1991, and

constant annual capacity payments of which the Company's share was $5.4 million
to $5.8 million per annum for each of the three power plants. Capacity payments
are significantly higher in the months of June through September. Bonus
payments are received monthly of which the Company's share was approximately
$1.0 million per annum for each of the three power plants.

  The Desert Peak and Roosevelt Hot Springs facilities ran at or near capacity
levels for each of the past three years. Steam sales from the Roosevelt Hot
Springs field, which was acquired in January 1991, remained relatively
unchanged at $2.2 million, $2.3 million, and $2.1 million in 1993, 1992 and
1991, respectively. Electric sales from Desert Peak were $5.1 million, $5.3
million and $4.0 million for the years 1993, 1992 and 1991, respectively.
Desert Peak was acquired in March 1991 and, accordingly, reflects only nine
months sales in 1991.
 
  Interest and other income increased in 1993 to $17.2 million from $10.2
million in 1992 and from $9.4 million in 1991. The increase reflects higher
average cash balances, interest income on notes receivable from the Coso Joint
Ventures and interest income on the Company's share of the cash reserves
established in the refinancing of the Coso Project debt in December 1992.
   
  The Company's cost per kWh* was as follows (in cents):

  The Company's expenses, excluding interest, increased as a general result of
the greater electricity production of the Coso Project. However, in 1993, plant
operations and general and administration costs per kWh decreased from 1992. In
1992, the Company's total expenses, excluding interest, were proportionally
less than the increase in electricity production of the Coso Project.
 
  The cost of plant operations increased to $25.4 million in 1993 from $24.4
million in 1992, an increase of 3.8%. The cost of plant operations increased to
$24.4 million in 1992 from $23.5 million in 1991, an increase of 3.9%. General
and administration costs remained relatively unchanged at $13.2 million in 1993
compared to $13.0 million in 1992. General and administration costs increased
to $13.0 million in 1992 from $12.5 million in 1991, a 4.5% increase. However,
for 1993 and 1992 both plant operations and general and administration costs
per kWh continued to decrease due to a proportionally greater increase in
electrical production than plant operations and general administration costs.
Plant cost per kWh decreased to 1.64 cents in 1993 from 1.65 cents in 1992 and
1.77 cents in 1991. General and administration costs per kWh decreased to 1.03
cents in 1993 from 1.04 cents in 1992 and 1.11 cents in 1991.
 
  Royalty costs increased to $8.3 million in 1993 from $7.7 million in 1992, an
increase of 7.3%. Royalty costs increased to $7.7 million in 1992 from $5.5
million in 1991, an increase of 40.1%, due to higher electrical sales and a
contractually scheduled increase in the 1992 royalty rate for the second and
third turbines of the Navy I plant. Overall, the royalty cost per kWh increased
to 0.65 cents in 1993 from 0.61 cents in 1992 and 0.49 cents in 1991.
   
  Depreciation and amortization expense increased to $17.8 million in 1993 from
$16.8 million and $14.8 million in 1992 and 1991, respectively, a 6.3% increase
from 1992 to 1993, and a 13.6% increase from 1991 to 1992. Depreciation and
amortization expense for 1993 was 1.39 cents per kWh compared to 1.33 cents in
1992 and 1.31 cents per kWh in 1991. The increase in 1993 was due to additional
capitalized costs associated with the settlement of litigation involving the
Mission Power Engineering Company ("MPE") and the Mission Power Group, as well
as additional wells and gathering systems. The increase in per kWh cost in 1992
was due largely to the costs of an increased number of production and injection
wells.     
   
  Interest expense, less amounts capitalized, increased to $23.4 million in
1993 from $14.9 million in 1992, an increase of 57.4% or 1.82 cents per kWh in
1993, compared to 1.17 cents in 1992. Net interest expense decreased to $14.9
million in 1992 from $24.4 million, or 2.16 cents per kWh in 1991. Net interest
expense in 1993 increased due primarily to the Company's higher weighted
average interest rate, higher levels of indebtedness associated with the Coso
Project and the issuance of convertible subordinated debentures in June 1993.
The short-term variable rate debt on the Coso Project was refinanced in 1992
with longer-term fixed rate debt. The weighted average interest rate on the
Coso Project debt was 7.9%, 5.4%, and 8.5% in 1993, 1992 and 1991,
respectively. Net interest expense decreased in 1992 from 1991 as a result of
low interest rates associated with the Coso Project's then variable rate debt.
       
  The provision for income taxes increased to $18.2 million in 1993 from $11.9
million and $8.3 million in 1992 and 1991, respectively. The effective tax rate
was 29.7%, 23.5% and 23.8% in 1993, 1992 and 1991. The increase in the 1993
effective tax rate was a result of adopting Financial Accounting Standard No.
109 ("FAS 109").     
 
  Income before the provision for income taxes increased 21.0% to $61.3 million
in 1993 from $50.7 million in 1992. Net income after a cumulative effect of a
change in accounting principle was $47.2 million and net income available to
common shareholders was $42.5 million or $1.11 per common share for the year
ended December 31, 1993. This compares to net income of $33.8 million after an
extraordinary item and net income available to common shareholders of $29.5
million or $.79 per common share for the year ended December 31, 1992. Net
income before cumulative effect of a change in accounting principle for the
year ended December 31, 1993 was $43.1 million or $1.00 per common share versus
net income before an extraordinary item of $38.8 million or $.92 per common
share in 1992. In 1991, income before the provision for income taxes was $34.9
million and net income and net income available to common shareholders was
$26.6 million or $.75 per share.

  Earnings per share were favorably impacted in 1992 by the Company's
repurchase of common shares during 1992 at an average price of approximately
$12.00 per share. The Company purchased common shares to be held as treasury
stock which were reissued upon the exercise of options and warrants.
 
LIQUIDITY AND CAPITAL RESOURCES
   
  The Company's cash and investments were $127.8 million at December 31, 1993
as compared to $54.7 million at December 31, 1992. In addition, the Coso
Project retained cash and investments in project control accounts of which the
Company's share was $14.9 million and $8.8 million at December 31, 1993 and
1992, respectively. Distributions out of the project control accounts are made
monthly to the Company for operation and maintenance and capital costs and
semiannually to each Coso Joint Venture partner for profit sharing under a
prescribed calculation subject to mutual agreement by the partners. In addition
to these liquid instruments, the Company recorded separately restricted cash of
$48.1 million and $62.5 million at December 31, 1993 and 1992, respectively.
The restricted cash balance in 1993 was comprised primarily of the Company's
proportionate share of Coso Project cash reserves for debt reserve funds and in
1992 included a contingency reserve fund, both of which were established in
conjunction with the Coso Project's refinancing of its previous bank debt.     
 
  Accounts receivable normally represents two months of revenues, and
fluctuates with both production and price per kWh.
 
  The balance due from/to the Coso Joint Ventures relates to operations,
maintenance, and management fees for managing the Coso Project. This amount
fluctuates based on the timing of billings and incurrence of costs.
   
  In December 1992, the Company refinanced the existing bank debt of the Coso
Project (see Note 5 of the Notes to the Consolidated Financial Statements).
Coso Funding Corp. ("Funding Corp."), a single-purpose corporation, was formed
to issue $560.2 million of notes for its own account and as an agent acting on
behalf of Navy I, BLM and Navy II Plants. The proceeds were used in part to
replace the outstanding Coso Project bank indebtedness and to provide funding
within the Coso Project for certain reserves. As of December 31, 1993 and 1992
the Company's proportionate share of the Coso Project loan was $246.9 million
and $263.6 million, respectively.     
 
  The Funding Corp. notes have remaining terms of up to eight years and
different fixed interest rates for each tranche. The underlying project loans
have identical terms as the Coso Project loans and are also non-recourse to the
Company.
 
  In connection with the Coso Project refinancing, the Company purchased
Community Energy Alternatives Incorporated's ("CEA") interest in the Coso
Project at the close of the Coso Project refinancing. See Note 5 of the Notes
to the Consolidated Financial Statements.
   
  On June 9, 1993, MPE and the Mission Power Group, subsidiaries of SCE Corp.,
and the Coso Joint Ventures reached a final settlement of all of their
outstanding disputes and claims relating to the construction of the Coso
Project. As a result of the various payments and releases involved in such
settlement, the Coso Joint Ventures agreed to make a net payment of $20.0
million to MPE from the cash reserves of the Coso Project contingency funds and
MPE agreed to release its mechanics' liens on the Coso Projects. After making
the $20.0 million payment, the remaining balance of the Coso Project
contingency funds (approximately $49.3 million) was used to increase the Coso
Project debt reserve fund from approximately $43.0 million to its maximum
fully-funded requirement of $67.9 million. The remaining $24.4 million balance
of the contingency fund was retained within the Coso Project for future capital
expenditures and for Coso Project debt service payments. Since the Coso Project
debt service reserve is fully funded in advance, Coso Project cash flows
otherwise intended to fund the Coso Project debt service reserve funds, subject
to satisfaction of certain covenants and conditions contained in the Coso Joint
Ventures' refinancing documents, are available for distribution to the Company
in its proportionate share.     
 
                                       22
<PAGE>
 
  On May 3, 1993, the transmission line dispute was settled and the
transmission line deposit of approximately $7.7 million was released to the
Company.
   
  In June 1993, the Company issued $100.0 million principal amount of 5%
convertible subordinated debentures (the "Convertible Subordinated Debentures")
due July 31, 2000. The Convertible Subordinated Debentures are convertible into
shares of the Company's common stock at any time prior to redemption or
maturity at a conversion price of $22.50 per share, subject to adjustment in
certain circumstances. Interest on the Convertible Subordinated Debentures is
payable semiannually in arrears on July 31 and January 31 each year, commencing
on July 31, 1993. The Convertible Subordinated Debentures are redeemable for
cash at any time on or after July 31, 1996 at a redemption price of (expressed
in percentages of the principal amount) 102%, 101%, 100% and 100% in 1996,
1997, 1998 and 1999, respectively. The Convertible Subordinated Debentures are
unsecured general obligations of the Company and subordinated to all existing
and future senior indebtedness of the Company.     
   
  The Senior Notes, of which $35.7 million aggregate principal amount are
currently outstanding, mature in March 1995 and bear interest at the rate of
12.0% per annum, plus contingent interest, calculated by reference to the
Company's share of the cash flow from the Coso Project through December 31,
1994. Simultaneous with the closing of the Offering, the Company intends to use
approximately $39.0 million of its existing cash balances to defease and
provide for the repayment of the entire aggregate principal amount of Senior
Notes outstanding. The Senior Notes prohibit the payment of cash dividends
unless the Company has a net worth of at least $50.0 million after payment of
such dividends, and dividends do not exceed 50% of accumulated net income
subsequent to December 31, 1987. The Senior Notes also place restrictions on
capital expenditures not related to the Coso Project.     
   
  Proceeds and benefits from warrants and options for shares of common stock
exercised in 1993 and 1992 aggregated approximately $1.4 million and $8.1
million, respectively. In addition, in August 1993, the Company acquired the
Ben Holt Co. ("BHCO"), a thirty person engineering firm for a combination of
cash and Company stock. In connection with this transaction, 87,000 common
shares were issued having an aggregate market value of $1.6 million.     
 
  The Company repurchased 157,000 common shares during 1993 for the aggregate
amount of $2.9 million. The Company purchased common stock to be held as
treasury stock in anticipation of their reissue once upon the exercise of
options. The Company repurchased 565,000 shares of common stock during 1992 at
an aggregate amount of $4.9 million. The shares were reissued during 1992 upon
the exercise of stock options.
   
  On October 13, 1992, the Company repurchased, and cancelled, certain warrants
exercisable for 1.025 million shares of unregistered common stock at $2.04 per
share, for a purchase price of $9.16 per share, or approximately $9.4 million
in the aggregate. Kiewit Energy Company ("Kiewit Energy") simultaneously
purchased and exercised other warrants to purchase 600,000 shares of
unregistered common stock at $2.04 per share, providing the Company with
proceeds of $1.2 million. On October 27, 1992, the Company repurchased and
cancelled warrants exercisable for 250,000 shares of unregistered common stock
at $2.04 per share, for a purchase price of $9.316 per share, or $2.3 million
in aggregate.     
 
  On November 15, 1992, the Company called the Company's Series B convertible
preferred stock, no par value (the "Series B preferred stock"), for conversion
into common stock. Each share of Series B preferred stock was converted into
two shares of common stock and, accordingly, the Company issued 954,900 shares
of common stock.
   
  In 1991, the Company and Kiewit Energy signed a stock purchase agreement and
related agreements (see Note 12 to the Consolidated Financial Statements). In
addition, in 1991 the Company issued 1,000 shares of its Series C redeemable
preferred stock to Kiewit Energy for $50,000 per share.     
 
  The Company is actively engaged in the acquisition of, and is seeking to
develop, construct, own and operate power projects utilizing geothermal and
other technologies, both domestically and internationally,
 
                                       23
<PAGE>
 
the completion of any of which is subject to substantial risk. The Company is
currently pursuing a number of international power project opportunities in
countries where private power generation programs have been initiated,
including the Philippines and Indonesia. Development can require the Company to
expend significant sums for preliminary engineering, permitting, legal and
other expenses in preparation for competitive bids which the Company may not
win or before it can be determined whether a project is feasible, economically
attractive or financeable. Successful development is contingent upon, among
other things, negotiation of construction, fuel supply and power sales
contracts with other project participants on terms satisfactory to the Company,
and receipt of required governmental permits and consents. Further, there can
be no assurance that the Company will obtain access to the substantial debt and
equity capital required for the acquisition or development and construction of
electric power projects. To the extent the Company engages in international
development efforts, the financing and development of projects entails
significant political and financial risks (including, without limitation,
uncertainties associated with first time privatization efforts in the countries
involved, currency exchange rate fluctuations, currency repatriation
restrictions, political instability, civil unrest and expropriation) and other
structuring issues that have the potential to cause substantial delays or that
the Company may not be fully capable of insuring against. There can be no
assurance that development efforts on any particular project, or the Company's
acquisition or development efforts generally, will be successful.
   
  In particular, the Company is developing a number of international projects,
for which it may have significant capital requirements. See "Business--
International Projects and Development Opportunities."     
   
  In addition to its international projects, the Company plans to incur
domestic geothermal capital expenditures in the aggregate amount of approximate
$30 million during 1994. The Company's planned capital spending includes, among
other things, its share of recurring Coso Project capital expenditures, as well
as the development of the Newberry Project in the Pacific Northwest.     
   
  The Company is constructing the Yuma Project, a 50 MW natural gas fired
cogeneration project in Yuma, Arizona. Engineering and equipment procurement
commenced in 1993. Capital expenditures of $10 million are anticipated through
the completion of the Yuma project by mid-year 1994. The capital expenditures
will be funded from existing cash balances and the Company's operating cash
flows.     
   
  Inflation has not had a substantial impact on the Company's operating
revenues and costs. The Coso Project's energy payments for electricity will
continue to be based upon scheduled rate increases through the initial ten year
period of each SO4 Agreement. Prior to the Coso Project refinancing, the
project loans relating to the Coso Project were generally for periods up to
twelve months at LIBOR plus a specified margin. Accordingly, the interest rates
on the loans varied and over the operating period resulted in fluctuating
interest payments. The refinanced Coso Project debt has fixed interest rates.
    
ADOPTION OF FINANCIAL ACCOUNTING STANDARD NO. 109
 
  On January 1, 1993, the Company adopted FAS 109. The adoption of FAS 109
changes the Company's method of accounting for income taxes from the deferred
method as required by Accounting Principles Board Opinion No. 11 to an asset
and liability approach. Under FAS 109, the net excess deferred tax liability as
of January 1, 1993 was determined to be $4.1 million. This amount is reflected
in 1993 income as the cumulative effect of a change in accounting principle. It
primarily represents the recognition of the Company's tax credit carryforwards
as a deferred tax asset. There was no cash impact to the Company upon the
required adoption of FAS 109. Under FAS 109, the effective tax rate utilized
increased at the time of adoption as a result of the tax credit carryforwards
being recognized as an asset and unavailable to reduce the current period's
effective tax rate for computing the Company's provision for income taxes. The
effective tax rate continues to be less than the statutory rate primarily due
to the depletion deduction and the generation of energy credits in 1993. The
significant components of the deferred tax liability are the temporary
differences between the financial reporting bases and income tax bases of the
power plant and the well and resource development costs, and in addition, the
offsetting benefits of operating loss carryforwards and investment and
geothermal energy tax credit and alternative minimum tax carryforwards.

                                    BUSINESS
   
  The Company, together with its subsidiaries, is primarily engaged in the
exploration for and development of geothermal resources and the development,
ownership and operation of environmentally responsible independent power
production facilities worldwide utilizing geothermal resources or other energy
sources, such as hydroelectric, natural gas, oil and coal. The Company was an
early participant in the domestic independent power market and is now one of
the largest geothermal power producers in the United States. The Company is
also actively pursuing opportunities in the international independent power
market. In the year ended December 31, 1993, the Company had revenues of $149.3
million, net income of $47.2 million, and as of that date, cash and investments
at the Company level of $127.8 million. Peter Kiewit Sons', Inc. ("Kiewit") is
a 36.6% stockholder (on a fully-diluted basis) in the Company and a participant
in certain of the Company's international private power projects.     
   
  Through its subsidiaries, the Company currently has significant ownership
interests in, and operates, four geothermal facilities that are qualified
facilities under the Public Utility Regulatory Policies Act of 1978 ("PURPA"),
which requires electric utilities to purchase electricity from qualified
independent power producers. See "--The Independent Power Production Market."
       
  Three of the Company's geothermal facilities, located together at the Naval
Weapons Center at China Lake, California (collectively, the "Coso Project"),
have an aggregate generating capacity of approximately 240 megawatts ("MW").
The Company is the managing general partner, operator and owner of an
approximately 50% interest in the Coso Project, which currently constitutes the
Company's primary source of revenues. Electricity generated by the Coso Project
is sold pursuant to three long-term "Standard Offer No. 4" contracts (the "SO4
Agreements") to Southern California Edison Company ("SCE"). In 1993, the Coso
Project achieved record MW production results and received the maximum level of
capacity and capacity bonus payments under the S04 Agreements. See "--The Coso
Project."     
   
  The Company also owns and operates a 10 MW geothermal power plant located at
Desert Peak, Nevada, which is a qualified facility that sells power to Sierra
Pacific Power Company, and operates and owns a 70% interest in a geothermal
steam field at Roosevelt Hot Springs, Utah, which supplies 25 MW of geothermal
steam to Utah Power & Light Company under a 30-year steam sales contract.
Pursuant to a memorandum of understanding, the Company has commenced early
stage site work on a proposed 30 MW geothermal project at Newberry, Oregon,
which is expected to be completed in early 1997 and to be wholly owned and
operated by the Company. See "--Other Domestic Projects and Development
Opportunities--Newberry."     
   
  Domestically, the Company plans to focus on developing and operating
geothermal power projects, an area in which the Company believes it has a
competitive advantage due to its geotechnical and project management expertise
and extensive geothermal leaseholdings. The Company intends to continue to
pursue geothermal opportunities in the Pacific Northwest where it has extensive
geothermal leaseholdings. In addition, the Company has diversified into other
environmentally responsible sources of power generation. The Company is
currently constructing a 50 MW natural gas fired cogeneration project in Yuma,
Arizona (the "Yuma Project"), which is expected to be wholly owned by the
Company and to sell electricity to San Diego Gas & Electric Company ("SDG&E")
under a 30-year power sales contract. The Company anticipates that this project
will be completed by mid-year 1994. See "--Other Domestic Projects and
Development Opportunities--Yuma." The Company expects future diversification
through the selective acquisition of partially developed or existing power
generating projects and intends to maintain a significant equity interest in,
and to operate, the projects which it develops or acquires.     
   
  The Company presently believes that the international independent power
market holds the majority of new opportunities for financially attractive
private power development in the next several years. The Company is actively
pursuing selected opportunities in nations where power demand is high and the
Company's geothermal resource development and operating experience, project
development expertise and strategic relationships are expected to provide it
with a competitive advantage. The Company believes that the opportunities to
successfully develop, construct, finance, own and operate international power
projects are increasing as several countries have initiated the privatization
of their power generation capacity and have     
 
                                       25
<PAGE>
 
solicited bids from foreign developers to purchase existing generating
facilities or to develop new capacity. Some of these countries, such as the
Philippines and Indonesia, also have extensive geothermal resources.
   
  The Company has recently entered into international joint venture agreements
with Kiewit and Distral S.A. ("Distral"), two firms with significant power
plant construction experience, in an effort to augment and accelerate the
Company's capabilities in foreign energy markets. Joint venture activities with
Distral will be conducted in South America, Central America and the Caribbean
and joint venture activities with Kiewit will be conducted in Asia, in
particular the Philippines and Indonesia, and in other regions not covered by
the Distral joint venture agreement. See "--International Projects and
Development Opportunities--International Joint Venture Agreements."     
   
  The Company has obtained "take-or-pay" power sales contracts for two
geothermal power projects in the Philippines aggregating approximately 300 MW
in capacity. The Upper Mahiao Project, a 120 MW geothermal facility with an
estimated total project cost of approximately $226 million, is expected to be
constructed on the island of Leyte and will be over 95% owned and operated by
the Company. A syndicate of international banks is expected to provide an
approximately $170 million project finance construction loan for the project.
The Company expects that a portion of the proceeds of the Offering will be used
to provide all or part of its approximately $56 million equity commitment to
such project. The Export-Import Bank of the United States ("ExIm Bank") is
expected to provide the term loan that would be used to refinance the
construction loan for this project, as well as political risk insurance to the
syndicate of commercial banks for the construction loan. The Company intends to
arrange for similar insurance on its equity investment through the Overseas
Private Investment Corporation ("OPIC") or from other governmental agencies or
commercial sources. The Company expects that both the construction and the term
loan agreements for the Upper Mahiao Project will be executed in April 1994 and
that the notice to proceed will be issued promptly thereafter under the
construction contract, which was executed in January 1994. Commercial operation
of this project is presently scheduled for mid-year 1996.     
   
  The Mahanagdong Project, a 180 MW geothermal project with an anticipated
total project cost of approximately $310 million, is expected to be operated by
the Company and owned 45% by the Company, 45% by Kiewit and up to 10% by
another industrial company. The Company intends to use a portion of the
proceeds of the Offering to fund all or part of its approximately $40 million
equity investment to the Mahanagdong Project, and to obtain political risk
insurance on its investment similar to that for the Upper Mahiao Project. The
Company is in the process of arranging construction financing for this project
from a syndicate of international banks on terms similar to those of the Upper
Mahiao construction loan. Such construction financing documentation is expected
to be executed by the end of the second quarter of 1994. The Company may use a
portion of the proceeds of the Offering to fund all or part of the
approximately $225 million in construction costs for the Project. The
construction financing is expected to close in mid-year 1994, with commercial
operation presently scheduled for mid-year 1997. See "--International Projects
and Development Opportunities--The Philippines."     
 
  The Company has been awarded the geothermal development rights to three
geothermal fields in Indonesia at Dieng, Patuha and Lampung/South Sumatra, the
initial phases of which could aggregate an additional generating capacity of
500 MW. The Company is currently negotiating power sales contracts for these
projects in Indonesia and, should such negotiations be successful and such
projects proceed, the Company intends to utilize a portion of the proceeds of
the Offering to fund equity investments and/or construction loans to these
projects. See "--International Projects and Development Opportunities--
Indonesia."
 
  The Company intends to use the net proceeds from the Offering (i) to fund
equity investments in, and the construction costs of, geothermal power projects
presently planned in the Philippines and Indonesia, (ii) to fund equity
investments in, and loans to, other potential international and domestic
private power projects and related facilities, (iii) for corporate or project
acquisitions permitted under the Indenture and (iv) for general corporate
purposes. As project loans are repaid, the Company may use the proceeds again
for any of such permitted uses. See "Use of Proceeds."

                    THE INDEPENDENT POWER PRODUCTION MARKET
 
  In the United States, the independent power industry expanded rapidly in the
1980's, facilitated by the enactment of PURPA. PURPA was enacted to encourage
the production of electricity by non-utility companies. According to the
Utility Data Institute and the North American Electricity Reliability Council,
independent power producers were responsible for about 50,000 MW, or 43%, of
the U.S. electric generation capacity which has come on line since 1980.
 
  As the size of United States independent power market has increased,
available domestic power capacity and competition in the industry have also
significantly increased. Over the past decade, obtaining a power sales contract
from a U.S. utility has generally become increasingly difficult, expensive and
competitive. Many states now require power sales contracts to be awarded by
competitive bidding, which both increases the cost of obtaining such contracts
and decreases the chances of obtaining such contracts as bids significantly
outnumber awards in most competitive solicitations. The federal Energy Policy
Act of 1992 is expected to further increase domestic competition.
   
  Due to the rapidly growing demand for new power generation capacity in many
foreign countries and resulting privatization of power development, significant
new markets for independent power generation now exist outside the United
States. The Company intends to take advantage of opportunities in these new
markets and to develop, construct and acquire generation projects outside the
United States. See "--International Projects and Development Opportunities."

                               GEOTHERMAL ENERGY
 
  Geothermal energy is derived from the heat of the earth's interior and may be
used to generate electricity where geological conditions are suitable for its
commercial extraction. These conditions exist where water contained within
porous or permeable rock formations comes sufficiently close to hot molten rock
to heat the water to temperatures of 400 degrees Fahrenheit or more. The heated
water then ascends towards the surface of the earth, where it can be extracted
by drilling geothermal wells. The geothermal reservoir is a renewable source of
energy if natural ground water sources and reinjection of extracted geothermal
fluids are adequate over the long-term to replenish the geothermal reservoir
after the withdrawal of geothermal fluids.
 
 
       [Schematic diagram illustrating how geothermal energy is derived.]
                                 
                              [ART GOES HERE]     
 
     
  The geothermal production wells are normally located within approximately one
to two miles of a power plant, as geothermal fluids cannot be transported
economically over longer distances. The geothermal fluids produced at the
wellhead consist of a mixture of hot water and steam. The mixture flows from
the wellhead through a gathering system of insulated steel pipelines to high
pressure separation vessels called separators. There, steam is separated from
the water and is sent to a demister in the power plant, where any remaining
water droplets are removed. This produces a stream of dry steam, which passes
through the high pressure inlet of a turbine generator, producing electricity.
The hot water previously separated from the steam at the high pressure
separators is piped to low pressure separators, where low pressure steam is
separated from the water and sent to the low pressure inlet of a turbine
generator. The hot water remaining after low pressure steam separation is
injected back into the geothermal resource.

                                THE COSO PROJECT
   
  The Coso Project, of which the Company owns approximately 50%, consists of
three qualified geothermal facilities with an aggregate generating capacity of
approximately 240 MW. Each of the three facilities (sometimes the "Navy I
Plant," the "BLM Plant" and the "Navy II Plant") is owned by a separate
partnership. The Company is the managing general partner for and operator of
the Coso Project. The Coso Project facilities are located on land leased by the
Company pursuant to long-term leases from the Navy and the BLM. In 1993, the
Coso Project produced an average output of 250 MW, and achieved the maximum
capacity and capacity bonus payments under the SO4 Agreements with SCE. The
payments under these contracts constituted approximately 94% of the operating
revenues of the Company in 1993.     
 
  The Coso geothermal resource is located in Inyo County, California,
approximately 150 miles northeast of Los Angeles. The Coso geothermal resource
is a liquid-dominated hot water resource contained within the heterogeneous
fractured granitic rocks of the Coso mountains. It is believed that the heat
source for the Coso geothermal resource is a hot molten rock body located
beneath the field. Water in the system is believed to be supplied from
groundwater flow from the Sierra Nevada mountains located approximately ten
miles west of the site.
   
  The Company believes, based on geological and engineering surveys and
analysis of wells drilled, that the Coso Project's geothermal resource is
sufficient to supply steam of adequate temperature and in sufficient quantities
for the respective terms of the SO4 Agreements. Because of the uncertainties
related to developing, exploring and operating geothermal resources and the
limited history of extracting the geothermal resource at the sites of the Navy
I Plant, the BLM Plant and the Navy II Plant, there is no assurance that the
geothermal reservoir will continue to supply steam at current levels for the
remaining terms of the SO4 Agreements. See "Investment Considerations--
Exploration, Development and Operation Uncertainties of Geothermal Energy
Resources."     
 
  The following sets forth certain information as of December 31, 1993
concerning the three facilities that comprise the Coso Project:

CERTAIN MATERIAL CONTRACTS     
 
  Set forth below is a summary of certain agreements material to the Coso
Project. Such summaries make use of certain terms defined in such agreements
and are qualified in their entirety by reference to such agreements, copies of
which may be obtained from the Company.
   
  The Navy Contract. In December 1979, the Company entered into a 30-year
contract (the "Navy Contract") with the Government of the United States, acting
through the Navy, which granted to the Company exclusive rights to explore,
develop and use the geothermal resource located on 3,520 acres within the China
Lake Naval Air Weapons Station near China Lake, California.     
 
  In respect of the electricity generated by Unit 1 of the Navy I Plant, the
Navy I Joint Venture is obligated to pay to the Navy $25 million on or before
December 31, 2009, which amount is, in part, secured by annual
 
                                       29
<PAGE>
 
contributions to a sinking fund, currently at $2,730,540. Annual payments to
the sinking fund are $600,000. Both the Navy I and Navy II Joint Ventures are
required to pay to the Navy royalties, or the equivalent thereof, for
electricity generated from the Navy I Plant (Units 2 and 3) and the Navy II
Plant. The percentage royalty due to the Navy for Units 2 and 3 of the Navy I
Plant equals 10% of gross revenues attributable to such facility through 1998,
15% through 2003 and 20% for the remaining term. The percentage royalty due to
the Navy for the Navy II Plant equals 4% of gross revenues attributable to such
facility through 1994, 10% through 1999, 18% through 2004 and 20% for the
remaining term.
 
  The Navy has the right to terminate the Navy Contract at any time by giving
the Navy I Joint Venture or the Navy II Joint Venture, or both, as applicable,
six months prior written notice, including for "reasons of national security,
national defense preparedness, national emergency, or for any reasons the
Contracting Officer shall determine that such termination is in the best
interest of the U.S. Government." In the event of such termination, the United
States Government is required to pay the Navy I Joint Venture, or the Navy II
Joint Venture, or both, as applicable, for its unamortized exploratory
investment and for its investment in installed power plant facilities, up to a
maximum amount based on the nameplate capacity of the turbine generators. The
total aggregate termination compensation for both Joint Ventures may not exceed
$352.5 million. There is no provision in the Navy Contract to compensate either
the Navy I or the Navy II Joint Venture for the loss of anticipated profits
resulting from such termination.
 
  The BLM Lease. On April 29, 1985 the Company and the BLM entered into a lease
(the "BLM Lease"), pursuant to which the Company acquired rights to explore,
develop and use the geothermal resource on 2,500 acres of land adjacent to the
land covered by the Navy Contract. The primary term of the BLM Lease is ten
years. The BLM Lease will extend automatically by its terms for so long as
geothermal steam is produced in commercial quantities, but in any event not in
excess of 40 years after the end of the initial term.
 
  The BLM Joint Venture pays a nominal annual rent of $2 to the BLM. Royalties
payable to the BLM under the BLM Lease are 10% of the amount (or value) of the
steam produced, 5% of any by-products, and 5% of commercially demineralized
water, payable monthly.
 
  BLM leases which have been extended due to production of commercial
quantities cannot be cancelled without a noticed hearing. BLM leases can be
terminated by operation of law as follows: (i) at the anniversary date, for
failure to pay the full amount of the annual rental by such date, and (ii) at
the end of the primary term, if there is no production in commercial
quantities, there is no producing well or actual drilling operations are not
being diligently prosecuted.
   
SO4 POWER SALES AGREEMENTS     
   
  Each of the Coso Joint Ventures has been assigned the rights to a long-term
SO4 Agreement with SCE. The SO4 Agreements relating to the Navy I Plant, the
BLM Plant and the Navy II Plant have remaining terms of approximately 17, 25
and 16 years, respectively, and provide for the payment of energy, capacity and
capacity bonus payments. Energy payments are fixed for the first ten years from
the date of firm power delivery (1987 for the Navy I Plant, 1989 for the BLM
Plant and 1990 for the Navy II Plant), with annual increases at a specified
rate, after which energy prices are based upon SCE's Avoided Cost. Average
energy prices under the SO4 Agreements for 1993 for the Navy I Plant, BLM Plant
and Navy II Plant were approximately 12.0 cents per kWh. For the period of
January 10, 1994 through February 13, 1994, SCE's Avoided Cost was 2.9 cents
per kWh (weighted average of mid-peak, off-peak and super off-peak). See
"Investment Considerations--Impact of Avoided Cost Pricing." Capacity payments
are fixed over the life of each contract. Additional capacity bonus payments
will be paid if the plant operates above an 85% capacity utilization level. The
SO4 Agreement for the Navy I Plant specifies a contract capacity of 75 MW after
August 1997. The SO4 Agreements for the BLM Plant and the Navy II Plant specify
a contract capacity of 67.5 MW.

NON-RECOURSE COSO PROJECT FINANCING     
 
  In December 1992, the Coso Joint Ventures refinanced the existing bank debt
of the Coso Project with the proceeds of the sale of approximately $560 million
in senior secured notes (the "Coso Notes") in a private placement pursuant to
Rule 144A under the Securities Act. The Coso Notes were issued by Funding
Corp., a corporation owned by the Coso Joint Ventures and formed exclusively
for the purpose of issuing the Coso Notes. Funding Corp. has lent the Coso
Joint Ventures all of the net proceeds of the sale of the Coso Notes in loans
referred to as the "Project Loans."
   
  Of the Coso Notes originally issued in December 1992, $47.9 million in
aggregate principal amount has matured and been paid in full when due. The
balance of the Coso Notes bear interest at fixed rates ranging from 6.50% to
8.87% and mature on dates ranging from June 30, 1994 to December 31, 2001.
Mandatory semiannual principal repayments are required with respect to certain
of the Coso Notes. The Coso Notes are currently rated "BBB-" by Standard &
Poor's Corporation, "Baa3" by Moody's Investors Service Inc., and "BBB" by Duff
& Phelps Credit Rating Co.     
   
  The obligations of each Coso Joint Venture under the Project Loans are non-
recourse obligations. Funding Corp. may look solely to each Coso Joint
Venture's pledged assets for satisfaction of such Coso Joint Venture's Project
Loan. Support loan and pledge arrangements between the Coso Joint Ventures have
the effect of cross-collateralizing each Project Loan, but only to the extent
of the other Coso Joint Ventures' available cash flow and, under certain
circumstances, the debt service reserve funds, and not as to other assets. The
Company is not liable for the repayment of the Coso Notes or the Project Loans.
       
  The terms of the financing restrict the ability of the Coso Joint Ventures to
distribute cash to their partners. In order to distribute cash, (i) no event of
default may exist under the Project Loans or the Coso Notes, and no notice of
such an impending event of default may have been received from the trustee
under the Indenture governing the Coso Notes, (ii) certain financial ratios
must be met, and (iii) certain thresholds must be met regarding the
availability of adequate geothermal resource for each Coso Plant and for the
Coso Project as a whole, as described in the Coso Notes Indenture. In addition,
the consent of the management committee of the Coso Joint Venture is required
for cash distributions.     
   
  In connection with the refinancing of the Coso Project, the Company
contributed approximately $9.8 million to CEGC-Mojave Partnership ("CEGC-
Mojave"), a newly formed partnership which used the proceeds to acquire an
indirect limited partnership interest in Caithness Coso Holdings, L.P., a
partner in the BLM Project and an affiliate of Caithness Corporation
("Caithness"), the Company's primary joint     
 
                                       31
<PAGE>
 
   
venture partner in the Coso Project. Certain cash flows of four Caithness
affiliates resulting from distributions from the Navy I, BLM and Navy II
Projects have been pledged to CEGC-Mojave . Under the terms of the CEGC-Mojave
partnership agreement, with certain exceptions, up to 25.0% of the cash flows
related to the Caithness affiliates will be distributed to such affiliates, and
the remainder will be distributed to the Company until the Company receives a
return of its initial investment plus a 17.0% annual rate of return, at which
time all distributions will revert to the Caithness affiliates.     
   
  Also in connection with the refinancing, the Coso Joint Ventures prepaid a
portion of certain notes to the Company in respect of prior advances made by
the Company to the Coso Project, and amended certain outstanding notes owing to
the Company. As a result, the BLM Joint Venture and the Navy II Joint Venture
have an aggregate of $19.0 million in principal amount of notes due to the
Company on March 19, 2002, which bear interest at 12 1/2% annually. The notes
are subordinated to the Project Loans and interest is not paid currently, but
accrues on a pay-in-kind basis until final maturity.     
   
REGULATORY AND ENVIRONMENTAL MATTERS     
 
  The Coso Joint Ventures are subject to environmental laws and regulations at
the federal, state and local levels in connection with the development,
ownership and operation of the plants. These environmental laws and regulations
generally require that a wide variety of permits and other approvals be
obtained for the construction and operation of an energy-producing facility and
that the facility then operate in compliance with such permits and approvals.
Failure to operate the facility in compliance with applicable laws, permits and
approvals can result in the levy of fines or curtailment of operations by
regulatory agencies.
 
  Management of the Coso Joint Ventures believes that the Coso Joint Ventures
are in compliance in all material respects with all applicable environmental
regulatory requirements and that maintaining compliance with current
governmental requirements will not require a material increase in capital
expenditures or materially affect its financial condition or results of
operations. It is possible, however, that future developments, such as more
stringent requirements of environmental laws and enforcement policies
thereunder, could affect the costs and the manner in which the Coso Joint
Ventures conduct their businesses.
   
INSURANCE     
 
  The Coso Project is insured for $600.0 million per occurrence for general
property damage and $600.0 million per occurrence for general property damage
and business interruption, subject to a $25,000 deductible for property damage
($500,000 for turbine generator and machinery) and a 15-day deductible on
business interruption. Catastrophic insurance (earthquake and flood) is capped
at $200.0 million per occurrence for property damage and $200.0 million per
occurrence for business interruption. Liability insurance coverage is $51.0
million (occurrence based) with a $10,000 deductible. Operators' extra expense
(control of well) insurance is $10.0 million per occurrence with a $25,000
deductible, which is non-auditable. The policies are issued by international
and domestic syndicates with each company rated A- or better by A.M. Best Co.
Inc. There can be no assurance, however, that earthquake, property damage,
business interruption or other insurance will be adequate to cover all
potential losses sustained by the Company or that such insurance will continue
to be available on commercially reasonable terms.
   
EMPLOYEES     
 
  The Coso Joint Ventures do not hire or retain any employees. All employees
necessary to the operation of the Coso Project are provided by the Company
under certain plant and field operations and maintenance agreements. As of
December 31, 1993, the Company employed approximately 160 people at the Navy I,
the BLM and the Navy II Plants, collectively.

             OTHER DOMESTIC PROJECTS AND DEVELOPMENT OPPORTUNITIES
 
DESERT PEAK
   
  The Company is the owner and operator of a 10 MW geothermal power plant at
Desert Peak, Nevada that is currently selling electricity to Sierra Pacific
Power Company under a power sales contract that expires December 31, 1995 and
that may be extended on a year-to-year basis as agreed by the parties. The
price for electricity under this contract is 6.3 cents per kWh, comprising an
energy payment of 1.8 cents per kWh (which is adjustable pursuant to an
inflation-based index) and a capacity payment of 4.5 cents per kWh. The Company
is currently negotiating the terms of an extension to this contract.     
 
ROOSEVELT HOT SPRINGS
   
  The Company operates and owns an approximately 70% interest in a 25 MW
geothermal steam field which supplies geothermal steam to a power plant owned
by Utah Power & Light Company ("UP&L") located on the Roosevelt Hot Springs
property under a 30-year steam sales contract. The Company obtained
approximately $20.3 million of the cash portion of the purchase price for the
properties under a pre-sale agreement with UP&L whereby UP&L paid in advance
the entire purchase price for the Company's proportionate share of the steam
produced by the steam field. The Company must make certain penalty payments to
UP&L if the steam produced does not meet quantity and quality requirements.
    
YUMA
 
  During 1992, the Company acquired a development stage 50 MW natural gas fired
cogeneration project in Yuma, Arizona. The Yuma Project is designed to be a
qualified facility under PURPA and to provide 50 MW (net) of electricity to
SDG&E over an existing 30-year power purchase sales contract. The electricity
is to be sold at SDG&E's Avoided Cost. The power will be transferred to SDG&E
over transmission lines constructed and owned by Arizona Public Service Company
("APS"). A transmission agreement has been executed between APS and the Yuma
Project but is subject to review by the Federal Energy Regulatory Commission.
   
  The power sales contract with SDG&E requires the Yuma Project to commence
reliable operation by December 31, 1994. The Company currently anticipates that
construction will be completed by mid-year 1994. The project entity has
executed steam sales contracts with an adjacent industrial entity to act as its
thermal host in order to maintain its status as a qualified facility, which is
a requirement of its SDG&E contract. Since the industrial entity has the right
to terminate the agreement upon one year's notice if a change in its technology
eliminates its need for steam, and in any case to terminate the agreement at
any time upon three years notice, there can be no assurance that the Yuma
Project will maintain its status as a qualified facility. However, if the
industrial entity terminates the agreement, the Company anticipates that it
will be able to locate an alternative thermal host in order to maintain its
status as a qualified facility or build a greenhouse at the site which the
Company believes would enable the project to maintain its qualified facility
status. A natural gas supply and transportation agreement has been executed
with Southwest Gas Corporation.     
 
  The Yuma Project is being constructed pursuant to a fixed price turnkey
contract with Raytheon Engineers & Constructors for approximately $43 million,
of which the Company has to date funded approximately $37 million from internal
sources. The Company currently intends to fund the balance from internal
sources as construction expenses are incurred.
 
NEWBERRY
   
  Under a Bonneville Power Administration ("BPA") geothermal pilot program, the
Company is developing a 30 MW geothermal project at Newberry, Oregon. Pursuant
to a memorandum of understanding executed in January 1993, the Company has
agreed to sell 20 MW of power to BPA and 10 MW to Eugene Water and Electric
Board ("EWEB") from the project. In addition, BPA has an option to purchase up
to an     
 
                                       33
<PAGE>
 
   
additional 100 MW of production from the project under certain circumstances.
In a public-private development effort, the Company is responsible for
development, permitting, financing, construction and operation of the project
(which will be 100% owned by the Company), while EWEB will cooperate in the
development efforts by providing assistance with government and community
affairs and sharing in the development costs (up to 30%). The project is
currently expected to commence commercial operation in 1997. The memorandum of
understanding provides that under certain circumstances the contracts may be
utilized at an alternate location.     
   
  A draft environmental impact study with respect to the project was completed
in January 1994 and is expected to be finalized in mid-year 1994, at which time
the Company expects to commence drilling of the geothermal wells and to execute
the power sales contracts, subject to obtaining all governmental permits and
approvals. The Company may use a portion of the proceeds of the Offering to
fund its equity investment in, and/or the construction costs of, the Newberry
Project.     
 
GLASS MOUNTAIN
 
  In March 1993, the Company completed the acquisition of an approximate 65%
interest in 26,000 acres of geothermal leaseholds at Glass Mountain in Northern
California, which include three successful production wells with an aggregate
existing capacity of between 15 to 30 MW. The Company believes that this
acreage represents one of the finest undeveloped geothermal reservoirs in the
country. The Company has attempted to negotiate the terms of a power sales
contract to exploit this geothermal resource, however, no agreement exists to
date.
 
              INTERNATIONAL PROJECTS AND DEVELOPMENT OPPORTUNITIES
 
OVERVIEW
   
  The Company presently believes that the international independent power
market holds the majority of new opportunities for financially attractive
private power development in the next several years, because the demand for new
generating capacity is growing more rapidly in foreign markets, especially
emerging nations, than in the United States. The World Bank estimates that
developing countries will need approximately 380,000 MW of new generating
capacity over the next decade. The need for such rapid expansion has forced
many countries to select private power development as their only practical
alternative and to restructure their legislative and regulatory schemes to
facilitate such development. The Company believes that this significant need
for power has created strong local support for private power projects in many
foreign countries and increased the availability of long-term multilateral
lending agency and foreign source financing and political risk insurance for
certain international private power projects, particularly those utilizing
indigenous fuel sources and renewable or otherwise environmentally responsible
generating facilities. The Company intends to focus its efforts on the
development, construction, ownership and operation of such projects.     
   
  In developing its international strategy, the Company intends to pursue
development opportunities in countries which it believes have an acceptable
risk profile and where the Company's geothermal resource development and
operating experience, project development expertise or strategic relationship
with Kiewit or local partners are expected to provide it with a competitive
advantage. The Company is currently pursuing a number of electric power project
opportunities in countries such as the Philippines and Indonesia, which have
initiated private power programs and have extensive geothermal resources. The
Company's development efforts include both so-called "green field" development,
in which the Company attempts to negotiate unsolicited power sales contracts
for new generation capacity or engages in competitive bids in response to
government agency or utility requests for proposals for new capacity, as well
as the acquisition of or participation in the joint development of projects
which are under development or already operating. To better position itself to
pursue international project development opportunities in the Asian market, the
Company recently established an office in Singapore to oversee its activities
in that region, including the Philippines and Indonesia. In pursuing
international projects, the Company intends to maintain a significant equity
interest in, and to operate, the projects that it develops or acquires.

     [Map of Pacific Basin showing countries having geothermal resources.]
 
 
 
  In order to compete more effectively internationally, the Company's strategy
is to diversify its project portfolio, reduce its future equity commitments and
leverage its capabilities in international projects by developing most
international projects on a joint venture basis. To that end, the Company has
recently entered into international joint venture agreements with Kiewit and
Distral (two firms with extensive power plant construction experience) in an
effort to augment and accelerate the Company's capabilities in foreign energy
markets. Joint venture activities with Distral will be conducted in South
America, Central America and the Caribbean and joint venture activities with
Kiewit will be conducted in Asia (in particular the Philippines and Indonesia)
and in other regions not covered by the Distral joint venture agreement. See
"--International Joint Venture Agreements."
 
FUNDING FOR INTERNATIONAL PROJECTS
 
  The Company intends to utilize a substantial portion of the net proceeds of
the Offering to fund all or part of its equity investments in, and loans to,
certain of the Company's international private power projects and related
facilities. Such proceeds will give the Company the ability to bid projects
without a financing contingency, to provide accelerated funding for
construction and to guarantee its equity commitments, which will enhance the
Company's competitive position in developing international projects. It is the
Company's experience that the amount of time necessary to negotiate and
conclude a construction credit facility for an international project is
significantly longer than the amount of time necessary to finance an already
proven and operating project. By having the financing available to commence
construction as soon as the principal project contracts and permits are
completed, the Company believes that it will be able to shorten the time
required to bring an international power project to commercial operation.
 
  The Company may use the proceeds of the Offering to provide a loan or other
financing for a project owned by a subsidiary or eligible joint venture to fund
construction of a domestic or international private power project and related
facilities. The Company does not intend to permit the drawdown of such loans or
other financing in any significant amount for the construction of such projects
until certain project milestones have been achieved, including signing power
sales contracts and financeable "turnkey" construction contracts and obtaining
permits and approvals that would be required for a traditional non-recourse
project financing. On or before the commencement of commercial operation of
such a project, the Company intends either to
 
                                       35
<PAGE>
 
   
retire its construction financing with the proceeds of a third-party non-
recourse project finance term loan or, if such a third-party loan is not then
available on terms acceptable to the Company or is otherwise disadvantageous,
to convert the construction loan into a medium or long-term facility provided
by the Company.     
   
  If the Company uses the proceeds of the Offering to provide a construction or
term loan to a subsidiary or joint venture project, payment of such loan will
generally be secured by substantially all the assets and cash flows of that
project, although the financing structure and collateral could also take other
forms such as preferred stock or partnership interests of the project entity.
To the extent the Company chooses to fund all or part of the construction costs
of a project on behalf of its joint venture partners, the Company intends to
negotiate appropriate terms and conditions, including equity transfer
restrictions and lending fees or other compensation for providing such
financing. The Company has no intention of advancing any equity funds on behalf
of its joint venture partners. Once construction financing made from the
proceeds of this Offering has been repaid, then the Company may use those
proceeds again for any of the permitted uses.     
 
  The proceeds of the Offering that are devoted to construction debt financing
for, and the equity contributions to, international power projects will be
subject to all of the usual risks that are inherent in project financing. In
addition, international projects may involve certain additional risks that are
not present to the same extent in domestic project financings, including
political, currency conversion and repatriation risks. In evaluating and
negotiating international projects, the Company intends to employ a strategy
whereby a substantial portion of the political and financial risks are, through
contract provisions or insurance coverage, borne by parties other than the
Company. However, there can be no assurance that such insurance coverage or
contract provisions will be available on commercially reasonable terms, or if
obtained, will be performed by the parties thereto. See "Investment
Considerations--Development Uncertainty" and "--Development Uncertainty Outside
the United States."
 
  The following is a brief description of the international joint ventures and
project development activities that the Company has undertaken to date.
 
INTERNATIONAL JOINT VENTURE AGREEMENTS
 
  As part of the Company's international development strategy, the Company
recently signed separate joint venture agreements with Kiewit and Distral.
These joint ventures provide the Company with strategic alliances with firms
possessing unique private power and construction expertise. The Company
believes these strategic joint venture relationships will augment and
accelerate its development capabilities in foreign energy markets and provide
it with a relative competitive advantage. In addition, the Company believes
that participation in these joint ventures will help the Company to diversify
its project risk profile, leverage its development capabilities and reduce
future requirements to raise additional equity for the Company's projects. The
Company also believes that it is important in foreign transactions to establish
strong relationships with local partners (such as Distral in South America and
P.T. Himpurna and P.T. ESA (each as defined below) in Indonesia) who are
knowledgeable of local cultural, political and commercial practices and who
provide a visible local presence and local project representation.
   
 Kiewit Joint Venture     
   
  On December 14, 1993, the Company signed a joint venture agreement with
Kiewit. Kiewit is one of the largest construction companies in North America
and has been in the construction business since 1884. Kiewit is a diversified
industrial company with approximately $2.0 billion in revenues in 1993 from
operations in construction, mining and telecommunications. Kiewit has built a
number of power plants in the United States and large infrastructure projects
and industrial facilities worldwide, and owns a 36.6% beneficial interest in
the Company.     
 
  The Kiewit joint venture agreement, which has an initial term of three years,
provides each party a right of first refusal to pursue jointly all "build, own
and operate" or "build, own, operate and transfer" power
 
                                       36

projects identified by the other party or its affiliates outside of the United
States, except in locations covered by the Distral joint venture agreement
described below. The Kiewit joint venture agreement provides that, if both
parties agree to participate in a project, they will share all development
costs equally, each of the Company and Kiewit will provide 50% of the equity
required for financing a project developed by the joint venture and the Company
will operate and manage any such project. The agreement contemplates a joint
development structure under which, on a project by project basis, the Company
will be the development manager, managing partner and/or project operator, an
equal equity participant with Kiewit and a preferred participant in the
construction consortium and Kiewit will be an equal equity participant and the
preferred turnkey construction contractor, with the construction consortium
providing customary security to project lenders (including the Company) for
liquidated damages and completion guarantees. The joint venture agreement may
be terminated by either party on 15 days written notice, provided that such
termination cannot affect the pre-existing contractual obligations of either
party.     
        
   
 Distral Joint Venture     
 
  On December 14, 1993, the Company entered into a joint venture agreement with
Distral of the Lancaster Distral Group, a South American engineering and
manufacturing company. Distral, a turnkey construction contractor and
manufacturer of boilers, generators and heavy equipment, has constructed,
engineered or supplied equipment to numerous coal, gas and hydroelectric power
plants located in Central and South America. The Company believes that, in
addition to its extensive experience in energy-related business, Distral brings
substantial knowledge of the customs and commercial practices in Central and
South America, as well as knowledge of the general power markets and specific
power project opportunities in such regions.
 
  The joint venture agreement, which has an initial term of three years,
provides that the joint venture will have the right of first refusal to jointly
pursue all power projects identified by the joint venture, the Company, Distral
or their affiliates (other than Kiewit) in the Caribbean, South America and
that part of Central America south of Mexico. The agreement provides that the
Company and Distral will share all development costs equally, if both parties
agree to participate in a project. The Company is required to provide at least
50% of the equity required to finance any project developed by the joint
venture; provided, however, that the Company may assign up to 50% of its equity
interest in any such project to Kiewit and its affiliates. The agreement
contemplates a joint development structure under which the Company and Distral
will jointly operate and maintain each joint venture project, with the Company
responsible for overall supervision and management. The Distral agreement may
be terminated at any time by the Company or Distral, provided that such
termination cannot affect the pre-existing contractual obligations of either
party.
 
THE PHILIPPINES
 
  The Company believes that increasing industrialization, a rising standard of
living and an expanding power distribution network has significantly increased
demand for electrical power in the Philippines. Currently, according to the
1993 Power Development Program of the National Power Corporation of the
Philippines ("NAPOCOR"), demand for electricity exceeds supply. NAPOCOR has
also reported that its ability to sustain current levels of electric production
from existing facilities has been limited due to frequent breakdowns in many of
its older electric generating plants and an extended drought, which has limited
hydroelectric generation. As a result, the Philippines has experienced severe
power outages, with Manila suffering significant daily brownouts during much of
1993. Although the occurrence of brownouts has been recently reduced, NAPOCOR
has said that it still anticipates significant energy shortages in the future.
 
  In 1993, the Philippine Congress, pursuant to Republic Act 7648, granted
President Ramos emergency powers to remedy the Philippines' energy crisis,
including authority to (i) exempt power projects from public bidding
requirements, (ii) increase power rates and (iii) reorganize NAPOCOR. Until
1987, NAPOCOR had a monopoly on power generation and transmission in the
Philippines. In 1987, then President Aquino issued
 
                                       37
<PAGE>
 
Executive Order No. 215, which grants private companies the right to develop
certain power generation projects, such as those using indigenous energy
sources on a "build-operate-transfer" or "build-transfer" basis. In 1990, the
Philippine Congress enacted Republic Act No. 6957, which authorizes private
development of priority infra-structure projects on a "build-operate-transfer"
and a "build-transfer" basis. In addition, under that Act, such power projects
are eligible for certain tax benefits, including exemption from Philippine
national income taxes for at least six years and exemption from, or
reimbursement for, customs duties and value added taxes on capital equipment to
be incorporated into such projects.
 
  In an effort to remedy the shortfall of electricity, the Republic of the
Philippines, NAPOCOR and the Philippine National Oil Company-Energy Development
Company ("PNOC-EDC") are jointly soliciting bids for private power projects.
The potential Philippine indigenous resources include geothermal, hydro and
coal, of which geothermal power has been identified as a preferred alternative.
The Philippine Government has elected to promote geothermal power development
due to the domestic availability and the minimal environmental effects of
geothermal power, in addition to other forms of power production. PNOC-EDC,
which is responsible for developing the Philippines' domestic energy sources,
has been successful in the exploration and development of geothermal resources.
 
 
 
                            [Map of the Philippines]
 
 
 
  The Company has been awarded and signed power contracts with PNOC-EDC for two
geothermal projects, Upper Mahiao and Mahanagdong, aggregating 300 MW. The
following is a summary description of certain information concerning these and
other projects as it is currently known to the Company. Since these projects
are still in development, however, there can be no assurance that this
information will not change over time. In addition, there can be no assurance
that development efforts on any particular project, or the Company's efforts
generally, will be successful. These summaries also include brief descriptions
of certain of the agreements material to these projects. Such summaries are
qualified in their entirety by reference to such agreements.
 
 
                                       38

 Upper Mahiao     
 
  The Company is negotiating the final terms of the construction and term
project financing for a 120 MW geothermal project to be located in the Greater
Tongonan area of the island of Leyte, Republic of the Philippines (the "Upper
Mahiao Project"). The Upper Mahiao Project will be built, owned and operated by
CE Cebu Geothermal Power Company, Inc. ("CE Cebu"), a Philippine corporation
that will be more than 95% indirectly owned by the Company. It will sell 100%
of its capacity on a "take-or-pay" basis (described below) to PNOC-EDC, which
will in turn sell the power to NAPOCOR for distribution to the island of Cebu,
located about 40 miles west of Leyte.
   
  The Company estimates that Upper Mahiao will have a total project cost of
approximately $226 million, including interest during construction, project
contingency costs and a debt service reserve fund. A consortium of
international banks is expected to provide an approximately $170 million
project-financed, nonrecourse construction loan, supported by political risk
insurance from ExIm Bank. The Company expects that the term loan for the
project will also be provided by ExIm Bank, and that both the construction and
the term loan agreements will be executed in April 1994. Shortly thereafter,
the Company expects to issue a notice to proceed to the contractor under the
EPC Contract (as defined below), with commercial operations scheduled for mid-
year 1996. The Company expects that a portion of the proceeds of the Offering
would be used to fund all or part of its $56 million equity commitment to the
Project. The Company intends to arrange for political risk insurance on this
equity investment through OPIC or from governmental agencies or commercial
sources.     
   
  The Upper Mahiao Project will be constructed by Ormat, Inc. ("Ormat") and its
affiliates pursuant to supply and construction contracts (collectively the
"Mahiao EPC Contract"), which, taken together, provide for the construction of
the plant on a fixed-price, date-certain, turnkey basis. Ormat is an
international manufacturer and construction contractor that builds binary
geothermal turbines; it has provided its equipment to several geothermal power
projects throughout the United States and internationally. The Mahiao EPC
Contract provides liquidated damage protection of 30% of the Mahiao EPC
Contract price. Ormat's performance under the Mahiao EPC Contract will be
backed by a completion guaranty of Ormat, by letters of credit, and by a
guaranty of Ormat Industries, Ltd., an Israeli corporation and the parent of
Ormat, in each case for the benefit of, and satisfactory to, the Project
lenders.     
   
  Under the terms of the Energy Conversion Agreement, executed on September 6,
1993 (the "Upper Mahiao ECA"), CE Cebu will build, own and operate the Project
during the two-year construction period and the ten-year cooperation period,
after which ownership will be transferred to PNOC-EDC at no cost. The
effectiveness of the Upper Mahiao ECA is subject to the satisfaction or waiver
of certain conditions prior to March 8, 1994 (subject to extension by agreement
of the parties which is anticipated by the Company to be readily available
through April 8, 1994) including finalization of the principal project
documents (including, a power purchase agreement between PNOC-EDC and NAPOCOR),
posting by Ormat of a construction performance bond in favor of PNOC-EDC in the
amount of approximately $11.8 million, obtaining permits and approvals from
various Philippine governmental authorities and arranging financing
commitments. In the event the parties are unable to satisfy such conditions
before the agreed upon effectivity date, either party may terminate the Upper
Mahiao ECA and such party shall reimburse the other party for its costs and
expenses incurred in connection with such agreement.     
 
  The Project will be located on land to be provided by PNOC-EDC at no cost; it
will take geothermal steam and fluid, also provided by PNOC-EDC at no cost, and
convert its thermal energy into electrical energy to be sold to PNOC-EDC on a
"take-or-pay" basis. Specifically, PNOC-EDC will be obligated to pay for the
electric capacity that is nominated each year by CE Cebu, irrespective of
whether PNOC-EDC is willing or able to accept delivery of such capacity. PNOC-
EDC will pay to CE Cebu a fee (the "Capacity Fee") based on the plant capacity
nominated to PNOC-EDC in any year (which, at the plant's design capacity is
approximately 95% of total contract revenues) and a fee (the "Energy Fee")
based on the electricity actually delivered to PNOC-EDC (approximately 5% of
total contract revenues). The Capacity Fee consists of three
 
                                       39
<PAGE>
 
separate components: a fee to recover the capital costs of the project, a fee
to recover fixed operating costs and a fee to cover return on investment. The
Energy Fee is designed to cover all variable operating and maintenance costs of
the power plant. Payments under the Upper Mahiao ECA will be denominated in
U.S. dollars, or computed in dollars and paid in Philippine pesos at the then-
current exchange rate, except for the Energy Fee, which will be used to pay
peso-denominated expenses. The ECA provides a mechanism to convert Philippine
pesos to dollars. Significant portions of the Capacity Fee and Energy Fee will
be indexed to U.S. and Philippine inflation rates, respectively. PNOC-EDC's
"take-or-pay" performance requirement, and its other obligations under the
Upper Mahiao ECA, are guaranteed by the Republic of the Philippines through a
performance undertaking.
   
  The payment of Capacity Fees is not excused if PNOC-EDC fails to deliver or
remove the steam or fluids or fails to provide the transmission facilities,
even if its failure was caused by a force majeure event. In addition, PNOC-EDC
must continue to make Capacity Fee payments if there is a force majeure event
(e.g., war, nationalization, etc.) that affects the operation of the Project
and that is within the reasonable control of PNOC-EDC or the government of the
Republic of the Philippines or any agency or authority thereof. If CE Cebu
fails to meet certain construction milestones or the power plant fails to
achieve 70% of its design capacity by the date that is 120 days after the
scheduled completion date (as that date may be extended for force majeure and
other reasons under the Upper Mahiao ECA), the Project may, under certain
circumstances, be deemed "abandoned," in which case the Project must be
transferred to PNOC-EDC at no cost, subject to any liens existing thereon.     
 
  PNOC-EDC is obligated to purchase CE Cebu's interest in the facility under
certain circumstances, including (i) extended outages resulting from the
failure of PNOC-EDC to provide the required geothermal fluid, (ii) changes in
tax, environmental or other laws which would materially adversely affect CE
Cebu's interest in the project, (iii) transmission failure, (iv) failure of
PNOC-EDC to make timely payments of amounts due under the Upper Mahiao ECA, (v)
privatization of PNOC-EDC or NAPOCOR, and (vi) certain other events. Prior to
completion of the Project, the buy-out price will be equal to all costs
incurred through the date of the buy-out, including all Project debt, plus an
additional rate of return on equity of ten percent per annum. In a post-
completion buy-out, the price will be the net present value at a ten percent
discount rate of the total remaining amount of Capacity Fees over the remaining
term of the Upper Mahiao ECA.
   
 Mahanagdong     
   
  The Mahanagdong project (the "Mahanagdong Project") is expected to be a 180
MW geothermal project, which will also be located on the island of Leyte. The
Mahanagdong Project will be built, owned and operated by CE Luzon Geothermal
Power Company, Inc. ("CE Luzon"), a Philippine corporation that is currently
expected to be indirectly owned as follows: 45% by the Company, 45% by Kiewit
and up to 10% by another industrial company. It will sell 100% of its capacity
on a take-or-pay basis (as described above for the Upper Mahiao Project) to
PNOC-EDC, which will in turn sell the power to NAPOCOR for distribution to the
island of Luzon.     
   
  The Company estimates that Mahanagdong will have a total project cost of
approximately $310 million, including interest during construction, project
contingency costs and a debt service reserve fund. The proposed capital
structure is 75% debt, with a construction and term loan of approximately $225
million, and 25% equity, or approximately $85 million in equity contributions.
The Company believes that political risk insurance from ExIm Bank for financing
of the procurement of U.S. goods and services and, if appropriate, will request
similar coverage from the Export-Import Bank of Japan for Japanese goods and
services is available. The Company is in the process of arranging construction
financing for the Project from a consortium of international banks, but may use
some of the proceeds of this Offering to provide all or part of the interim
construction debt financing of $225 million. Construction of the Project is
expected to commence in mid-year 1994, with commercial operation presently
scheduled for mid-year 1997. The Company also intends to provide some or all of
its approximately $40 million share of the $85 million equity     
 
                                       40
<PAGE>
 
contribution from these proceeds, and to arrange for political risk insurance
on this investment through OPIC or from governmental agencies or commercial
sources.
   
  The Mahanagdong Project will be constructed by a consortium consisting of
Kiewit Construction Group, Inc. ("KCG") and The Ben Holt Co., Inc. ("BHCO")
(the "EPC Consortium") pursuant to fixed-price, date-certain, turnkey supply
and construction contracts (collectively the "Mahanagdong EPC Contract"). The
obligations of the EPC Consortium under the Mahanagdong EPC Contract will be
supported by letters of credit, bonds, guarantees or other acceptable security
in an aggregate amount equal to approximately 30% of the Mahanagdong EPC
Contract's price, plus a joint and several guaranty of each of the EPC
Consortium members. KCG, a wholly-owned subsidiary of Kiewit, will be the lead
member of the EPC Consortium, with an 80% interest. KCG performs construction
services for a wide range of public and private customers in the U.S. and
internationally. Construction projects undertaken by KCG during 1992 included:
transportation projects, including highways, bridges, airports and railroads;
power facilities; buildings and sewer and waste disposal systems; with the
balance consisting of water supply systems, utility facilities, dams and
reservoirs. KCG accounted for 80% of Kiewit's revenues, contributing $1.7
billion in revenues in 1993. KCG has an extensive background in power plant
construction.     
   
  BHCO will provide design and engineering services for the EPC Consortium,
holding a 20% interest. BHCO, wholly-owned by the Company, is a California
based engineering firm with over 25 years of geothermal experience,
specializing in feasibility studies, process design, detailed engineering,
procurement, construction and operation of geothermal power plants, gathering
systems and related facilities. The Company will provide a guarantee of BHCO's
obligations under the Mahanagdong EPC Contract.     
 
  The terms of the Energy Conversion Agreement (the "Mahanagdong ECA"),
executed on September 18, 1993, are substantially similar to those in the Upper
Mahiao ECA. The Mahanagdong ECA provides for a three-year construction period,
and its effectivity deadline date is in July 1994. All of PNOC-EDC's
obligations under the Mahanagdong ECA will be guaranteed by the Republic of the
Philippines through a performance undertaking. The Capacity Fees are expected
to be approximately 97% of total revenues at the expected capacity levels and
the Energy Fees are expected to be approximately 3% of such total revenues.
   
 Casecnan     
   
  The Company has been granted exclusive rights to negotiate an energy sales
contract with NAPOCOR and a water sales contract with the National Philippine
Irrigation Administration in connection with a proposed 60 MW hydro-electric
generating facility to be located in the Casecnan area on the island of Luzon.
These contracts will be structured as take-or-pay capacity and energy
agreements, with capacity payments representing the bulk of the revenues.
Negotiations have only recently commenced on this potential project, and there
can be no assurance at this time that any agreement will be reached by the
parties.     
 
                                       41

INDONESIA
 
  The Republic of Indonesia is experiencing demand for electrical power that
exceeds current supply, and has a number of promising geothermal reservoirs.
Recent Indonesian legislation has facilitated foreign ownership and operation
of private electrical power generation and transmission facilities. The
Company's subsidiaries are currently negotiating several potential project
agreements for geothermal power facilities in Indonesia, and if one or more of
those projects proceeds, it intends to utilize a portion of the proceeds of
this Offering in connection with such projects.
 
 
                               [MAP OF INDONESIA]
 
 
 
  The following is a summary description of certain information concerning
these projects as it is currently known to the Company. Since these projects
are still in development, however, there can be no assurance that this
information will not change materially over time. In addition, there can be no
assurance that development efforts on any particular project, or the Company's
efforts generally, will be successful.
   
 Dieng     
 
  Through memoranda of understanding executed by Perusahaan Pertambangan Minyak
Dan Gas Bumi Negara ("Pertamina"), the Indonesian national oil company, and
assigned to the Company, the Company has been awarded the exclusive right to
develop geothermal resources in the Dieng region of central Java, Indonesia
(the "Dieng Project"). A subsidiary of the Company has entered into a Joint
Development Agreement with P.T. Himpurna Enersindo Abadi ("P.T. HEA"), its
Indonesian partner, which is a subsidiary of Himpurna, an association of
Indonesian military veterans, whereby the Company and P.T. HEA have agreed to
work together on an exclusive basis to develop the Dieng Project (the "Dieng
JV"). The Dieng JV is expected to be structured such that subsidiaries of the
Company will have a 45% interest, subsidiaries of Kiewit will have the option
to take a 45% interest and P.T. HEA will have a 10% interest in the Project.
The Dieng JV expects to conduct geothermal exploration and development in the
Dieng field, to build, own and operate power generating facilities and to sell
the power generated to Perusahaan Umum Listrik Negara ("PLN"), the Indonesian
national electric utility.
 
                                       42
<PAGE>
 
  The Dieng JV and Pertamina are currently negotiating a proposed Joint
Operation Contract (the "Dieng JOC") pursuant to which Pertamina would
contribute the geothermal field and the wells and other facilities presently
located thereon and the Dieng JV initially would build, own and operate four
power production units comprising an aggregate of 220 MW. The Dieng JV will
accept the field operation responsibilities and geothermal resource risk in
connection with the Dieng Project, and the Dieng JV will be responsible for
developing and supplying the geothermal steam and fluids required to operate
the plants. The current proposed Dieng JOC would expire (subject to extension
by mutual agreement) on the date which is the later of (i) 42 years following
completion of well testing and (ii) 30 years following the date of commencement
of commercial operation of the final unit completed. Upon the expiration of the
proposed Dieng JOC, all facilities would be transferred to Pertamina at no
cost. Under the proposed Dieng JOC, the Dieng JV would be required to pay
Pertamina a production allowance equal to three percent of the Dieng JV's net
operating income from the Dieng Project, plus a further percentage based upon
the negotiated value of existing Pertamina geothermal production facilities
that the Company expects will be contributed by Pertamina.
 
  The Dieng JV and Pertamina are currently negotiating a proposed "take-or-pay"
Energy Sales Contract (the "Dieng ESC") with PLN whereby PLN would agree to
purchase and pay for all electricity delivered or capacity made available from
the Dieng Project for a term equal to that of the Dieng JOC. Under the current
draft, the price paid for electricity would equal a base energy price per kWh
multiplied by the number of kWh the plants deliver or are "capable of
delivering," whichever is greater. Electricity revenue payments would also be
adjusted for inflation and fluctuations in exchange rates.
 
  Assuming execution of the Dieng JOC and the Dieng ESC, the Company presently
intends to begin well testing by the second quarter of 1994 and to commence
construction of an initial 55 MW unit in the fourth quarter of 1994, and then
to proceed on a modular basis with construction of three additional units to
follow shortly thereafter, resulting in an aggregate first phase at this site
of 220 MW. The Company estimates that the total project cost of these units
will be approximately $450 million. The Company anticipates that the Dieng
Project will be designed and constructed by a consortium consisting of KCG and
BHCO, and that the Company (through a subsidiary) will be responsible for
operating and managing the Dieng Project.
   
  The Dieng field has been explored domestically for over 20 years and BHCO has
been active in the area for more than five years. The Company has a significant
amount of data, which it believes to be reliable as to the production capacity
of the field. However, a number of significant steps, both financial and
operational, must be completed before the Dieng Project can proceed. These
steps, none of which can be assured, include obtaining required regulatory
permits and approvals, entering into the Dieng JOC, undertaking and completing
the well testing contemplated by the Dieng JOC, entering into the Dieng ESC,
the construction agreement and other project contracts and arranging financing.
       
 Patuha     
   
  The Company has also negotiated a memorandum of understanding and expects to
execute a definitive agreement with Pertamina for the exclusive geothermal
development rights with respect to the Patuha geothermal field in Java,
Indonesia (the "Patuha Project"). The Company has entered into an agreement to
establish a joint venture for Patuha with P.T. Enerindo Supra Abadi, an
Indonesian company ("P.T. ESA") (the "Patuha JV"). P.T. ESA is an affiliate of
the Bukaka Group, which has extensive experience in general construction,
fabrication and electrical transmission construction in Indonesia. In exchange
for project development services, P.T. ESA is expected to receive a 10% equity
interest in the Patuha Project with an option to acquire an additional 20%
interest for cash upon the satisfaction of certain conditions. Subject to the
exercise of that option, subsidiaries of the Company will have a 45% interest
and subsidiaries of Kiewit will have the option to take a 45% interest in the
Patuha Project.     
   
  The Patuha JV is currently negotiating both a joint operation contract
("JOC") and an energy sales contract ("ESC"), each of which currently contains
terms substantially similar to those described above for the Dieng Project. The
Patuha JV presently intends to proceed on a modular basis like the Dieng
Project,     
 
                                       43
<PAGE>
 
with an initial 55 MW unit to be built followed by three additional units, in
total aggregating 220 MW. The Company estimates that the total cost of these
four units will be approximately $450 million. Assuming execution of both a JOC
and an ESC, field development is expected to commence in the first quarter of
1995 with construction of the first unit expected to begin by mid-year 1996.
 
  The Patuha Project remains subject to a number of significant uncertainties,
as described above in connection with the Dieng Project, and there can be no
assurance that the Patuha Project will proceed or reach commercial operation.
   
 Lampung/South Sumatra     
   
  The Company and P.T. ESA have also formed a joint venture (the "Lampung JV")
to pursue development of geothermal resources in the Lampung/South Sumatra
regions (the "Lampung Project"). The Lampung JV is presently exploring several
geothermal fields in this region and is negotiating a memorandum of
understanding for a JOC and ESC for these prospects containing terms
substantially similar to those described above for the Dieng Project.     
 
  The Company presently intends to develop the Lampung Project and other
possible Indonesian projects using a structure similar to that contemplated for
the Dieng Project, with the same construction consortium, similar equipment and
similar financing arrangements.
 
  The Lampung Project remains subject to a number of significant uncertainties,
as described above for the Dieng Project, and there can be no assurance that
the Company will pursue the Lampung Project or that it will proceed or reach
commercial operation.
 
                               LEGAL PROCEEDINGS
 
  The Company is not a party to any material legal proceedings.

                     CERTAIN TRANSACTIONS AND RELATIONSHIPS
 
TRANSACTIONS AND RELATIONSHIPS WITH KIEWIT AND ITS AFFILIATES
 
 Stock Purchase and Related Agreements
   
  The Company and Kiewit Energy are parties to a stock purchase agreement and
related agreements, dated as of February 18, 1991, pursuant to which Kiewit
Energy purchased 4,000,000 shares of Common Stock at $7.25 per share and
received options to buy 3,000,000 shares of Common Stock at a price of $9.00
per share exercisable over three years, and an additional 3,000,000 shares of
Common Stock at a price of $12.00 per share exercisable over five years
(subject to customary adjustments).     
 
  In connection with such stock purchase, the Company and Kiewit Energy also
entered into certain other agreements pursuant to which, among other things,
(i) Kiewit Energy and its affiliates agreed, subject to certain conditions, not
to acquire more than 34% of the outstanding Common Stock (the "Standstill
Percentage") for a five-year period, (ii) Kiewit Energy became entitled to
nominate at least three of the Company's directors, (iii) Kiewit Energy agreed
that Kiewit and its affiliates would present to the Company any opportunity to
acquire, develop, operate or own a geothermal resource or geothermal power
plant, and (iv) the Company and Kiewit Energy agreed to use their best efforts
to negotiate and execute a definitive joint venture agreement relating to the
development of certain geothermal properties in Nevada and Utah. Messrs. Crowe,
Jaros and Scott are the current Board nominees of Kiewit Energy.
   
  In June 19, 1991, the Board of Directors approved a number of amendments to
the stock purchase agreement and the related agreements. Pursuant to such
amendments, the Company reacquired from Kiewit Energy the rights to develop the
Nevada and Utah properties, and Kiewit Energy agreed to exercise options to
acquire 1,500,000 shares of Common Stock at $9.00 per share, providing the
Company with $13.5 million in cash. The Company also extended the term of the
$9.00 and $12.00 options to seven years, modified certain of the other terms of
these options, granted to Kiewit Energy an option to acquire an additional
1,000,000 shares of the outstanding Common Stock at a price of $11.625 per
share exercisable over ten years (the closing price for the shares on the
American Stock Exchange on June 18, 1991), and increased the Standstill
Percentage from 34% to 49%.     
 
 Joint Venture Agreements
 
  The Company entered into a joint venture agreement with Kiewit on December
14, 1993. The agreement provides a framework for the joint development of power
projects located in the Philippines, Indonesia and countries outside the region
covered by the joint venture agreement between the Company and Distral. See

Joint Venture Agreements."
 
 Other Transactions
   
  Gilbert Industrial. Commencing in 1991, Gilbert Industrial Corporation
("Gilbert"), a wholly-owned subsidiary of Kiewit, constructed modifications to
the geothermal power production facility owned by the BLM Joint Venture.
Through the year ended December 31, 1993, the Company's portion of amounts paid
by the BLM Joint Venture to Gilbert under this contract was approximately $2.5
million.     
 
  Aircraft Lease. The Company is subleasing to Midwest Aviation, a division of
a subsidiary of Kiewit, an airplane leased by the Company from an unaffiliated
third-party aircraft lessor (the "Lessor"). The Company pays monthly lease
payments of $38,669 to the Lessor. Midwest Aviation, in turn, pays monthly
sublease payments of $25,000 to the Company. Both the lease and the sublease
terminate on July 31, 1995. Upon termination of the lease, the Company has the
right to purchase the aircraft; Midwest Aviation, in turn, has the right to
purchase the aircraft from the Company for the price paid by the Company.

and, unless the Company agrees to make other arrangements, will be paid by
checks mailed to such Holders. Interest on overdue principal and (to the extent
permitted by applicable law) on overdue interest will accrue at a rate of 1% in
excess of the rate per annum borne by the Notes. Interest on the Notes will be
computed on the basis of a 360-day year of 12 30-day months.     
 
                                       51

  The Notes will be issued without coupons and in fully registered form only in
denominations of $1,000 and integral multiples thereof.

  The Company is subject to the informational reporting requirements of
Sections 13 and 15(d) under the Exchange Act and, in accordance therewith,
files certain reports and other information with the Commission. See "Available
Information." In addition, if Sections 13 and 15(d) cease to apply to the
Company, the Company will covenant in the Indenture to file comparable reports
and information with the Trustee and the Commission, and mail such reports and
information to Noteholders at their registered addresses, for so long as any
Notes remain outstanding.
 
OPTIONAL REDEMPTION
 
  The Notes may be redeemed at the Company's option, in whole or in part, at
any time on or after January 15, 1999 and prior to maturity, upon not less than
30 nor more than 60 days' prior notice, at the following redemption prices
(expressed in percentages of principal amount), plus accrued interest (if any)
to the date of redemption, if redeemed during the 12-month period commencing on
or after January 15 of the years set forth below:
 
<TABLE>
<CAPTION>
             YEAR                     REDEMPTION PRICE

             2001 and thereafter.....       100%
</TABLE>
 
  If less than all the outstanding Notes are to be redeemed, the Notes or
portions of Notes to be redeemed will be selected by the Trustee pro rata or
otherwise in such manner as the Trustee deems to be fair and appropriate in the
circumstances.
 
  The Notes will not be subject to any mandatory sinking fund.
 
RANKING
   
  The Notes will be general, unsecured senior obligations of the Company and
will rank pari passu with all other unsecured senior indebtedness of the
Company. As of December 31, 1993, the Company's total consolidated indebtedness
was $382.6 million (excluding deferred income and redeemable preferred stock),
its total consolidated assets were $716.0 million and its stockholders' equity
was $211.5 million. At such date, on a pro forma basis, after giving effect to
the completion of this Offering and the Company's planned defeasance of its
Senior Notes, the Company's total consolidated indebtedness (excluding deferred
income and redeemable preferred stock) would have been $746.9 million, its
total consolidated assets would have been $1,077.0 million and its
stockholders' equity would have been $208.2 million. See "Capitalization" and
"Selected Historical Consolidated Financial and Operating Data." The Indenture
does not limit the amount of Non-Recourse Debt which may be incurred by the
Company or at the subsidiary or project level. As a result, the Notes are
effectively subordinated to any secured Non-Recourse Debt of the Company and to
indebtedness and other obligations of the Company's subsidiaries and the
partnerships and joint ventures in which the Company has direct or indirect
interests. See "Investment Considerations--High Leverage; Additional Debt
Permitted at Subsidiary or Project Level; Priority of Project Debt."     
 
CERTAIN COVENANTS
 
  The Indenture will contain certain covenants, including the ones summarized
below, which covenants will be applicable (unless they are waived or amended or
unless the Notes are defeased, see "Defeasance" below) so long as any of the
Notes are outstanding.
 
 
                                       52
<PAGE>
 
   
 Limitation on Debt     
 
  The Company will not Incur any Debt, including Acquisition Debt, unless,
after giving effect to the Incurrence of such Debt and the receipt and
application of the proceeds therefrom, the Fixed Charge Ratio of the Company
would be equal to or greater than 2.0 to 1.
   
  Notwithstanding the foregoing, the Company may Incur each and all of the
following: (i) Company Refinancing Debt, (ii) Debt of the Company to any of its
Restricted Subsidiaries or any Eligible Joint Venture that is expressly
subordinated in right of payment to the Notes, provided that any transfer of
such Debt by a Restricted Subsidiary or an Eligible Joint Venture (other than
to another Restricted Subsidiary or another Eligible Joint Venture), or any
transfer of the Company's ownership interest, or a portion thereof, in such
Restricted Subsidiary or such Eligible Joint Venture or the interest, or a
portion thereof, of Kiewit in a Permitted Joint Venture or an Eligible Joint
Venture (which transfer has the effect of causing such Restricted Subsidiary or
such Eligible Joint Venture to cease to be a Restricted Subsidiary or an
Eligible Joint Venture, as the case may be), will be deemed to be an Incurrence
of Debt that is subject to the provisions of this covenant other than this
clause (ii), (iii) Debt in an aggregate principal amount not to exceed $50
million outstanding at any one time may be issued under or in respect of
Permitted Working Capital Facilities, (iv) Non-Recourse Debt Incurred in
respect of a Permitted Facility in which the Company has a direct interest, (v)
Debt in respect of Currency Protection Agreements or Interest Rate Protection
Agreements, (vi) Purchase Money Debt, provided that the amount of such Debt
(net of any original issue discount) does not exceed 90% of the fair market
value of the Property acquired, (vii) the Notes and other Debt outstanding as
of the date of original issuance of the Notes (other than Debt to the extent
that it is extinguished, retired, defeased or repaid in connection with the
original issuance of the Notes), including Debt that is Incurred in respect of
interest or discount on such Debt (or Redeemable Stock issued as dividends in
respect of Redeemable Stock) pursuant to the terms of the agreement or
instrument that governs such Debt (or such Redeemable Stock) as in effect on
the date of original issuance of the Notes and (viii) Debt in an aggregate
principal amount not to exceed $50 million outstanding at any one time.     
 
 Limitation on Subsidiary Debt
 
  The Company will not permit any of its Restricted Subsidiaries or any
Eligible Joint Venture, to Incur any Debt.
   
  Notwithstanding the foregoing, each and all of the following Debt may be
Incurred by a Restricted Subsidiary or an Eligible Joint Venture: (i) Debt
Outstanding as of the date of original issuance of the Notes, (ii) Debt owed by
a Restricted Subsidiary or an Eligible Joint Venture to the Company or another
Restricted Subsidiary of the Company or another Eligible Joint Venture that
either directly or indirectly owns all or a portion of the Company's interest
in, or directly or indirectly is owned by, such Restricted Subsidiary or such
Eligible Joint Venture, as the case may be, and that does not own any Permitted
Facility or a direct or indirect interest therein, other than the Permitted
Facility or any other Permitted Facility that is located on the same localized
geothermal reservoir or a direct or indirect interest therein owned by such
Restricted Subsidiary or Eligible Joint Venture, (iii) Non-Recourse Debt
Incurred in respect of a Permitted Facility in which such Restricted Subsidiary
or such Eligible Joint Venture has a direct or an indirect interest (which may
include Construction Financing provided by the Company pursuant to clause (ii)
of the definition of "Permitted Investment" below), (iv) Subsidiary Refinancing
Debt, (v) Acquired Debt, (vi) Debt in respect of Currency Protection Agreements
or Interest Rate Protection Agreements and (vii) Permitted Funding Company
Loans.     
 
 Limitation on Restricted Payments
 
  The Company will not, and will not permit any of its Restricted Subsidiaries
or any Eligible Joint Venture to, directly or indirectly, make any Restricted
Payment unless at the time of such Restricted Payment and after giving effect
thereto (a) no Event of Default and no event that, after the giving of notice
or lapse of time or both, would become an Event of Default, has occurred and is
continuing, (b) the Company could Incur at least $1 of Debt under the provision
described in the first paragraph of "Limitation on Debt" above and (c) the
aggregate amount of all Restricted Payments made by the Company, its Restricted
Subsidiaries
 
                                       53
<PAGE>
 
   
and the Eligible Joint Ventures (the amount so made, if other than in cash, to
be determined in good faith by the Chief Financial Officer, as evidenced by an
Officers' Certificate, or, if more than $15 million, by the Board of Directors,
as evidenced by a Board resolution) after the date of original issuance of the
Notes, is less than the sum (without duplication) of (i) 50% of the Adjusted
Consolidated Net Income of the Company for the period (taken as one accounting
period) beginning on the first day of the first fiscal quarter that begins
after the date of the original issuance of the Notes and ending on the last day
of the fiscal quarter immediately prior to the date of such calculation,
provided that if throughout any fiscal quarter within such period the Ratings
Categories applicable to the Notes are, rated Investment Grade by Standard &
Poor's Corporation, and Moody's Investors Service, Inc. (or if both do not make
a rating of the Notes publicly available, an equivalent Rating Category is made
publicly available by another Rating Agency), then 75% (instead of 50%) of the
Adjusted Consolidated Net Income (if more than zero) with respect to such
fiscal quarter will be included pursuant to this clause (i), and provided
further that if Adjusted Consolidated Net Income for such period is less than
zero, then minus 100% of the amount of such net loss, plus (ii) 100% of the
aggregate net cash proceeds received by the Company from and after the date of
original issuance of the Notes from (A) the issuance and sale (other than to a
Restricted Subsidiary or an Eligible Joint Venture) of its Capital Stock
(excluding Redeemable Stock, but including Capital Stock other than Redeemable
Stock issued upon conversion of, or in exchange for Redeemable Stock or
securities other than its Capital Stock), (B) the issuance and sale or the
exercise of warrants, options and rights to purchase its Capital Stock (other
than Redeemable Stock) and (C) the issuance and sale of convertible Debt upon
the conversion of such convertible Debt into Capital Stock (other than
Redeemable Stock), but excluding the net proceeds from the issuance, sale,
exchange, conversion or other disposition of its Capital Stock (I) that is
convertible (whether at the option of the Company or the holder thereof or upon
the happening of any event) into (x) any security other than its Capital Stock
or (y) its Redeemable Stock or (II) that is Capital Stock referred to in
clauses (ii) and (iii) of the definition of "Permitted Payment", plus (iii) the
net reduction in Investments of the types specified in clauses (iv) and (v) of
the definition of "Restricted Payment" that result from payments of interest on
Debt, dividends, or repayment of loans or advances, the proceeds of the sale or
disposition of the Investment or other return of the amount of the original
Investment to the Company, the Restricted Subsidiary or the Eligible Joint
Venture that made the original Investment from the Person in which such
Investment was made, provided that (x) the aggregate amount of such payments
will not exceed the amount of the original Investment by the Company or such
Restricted Subsidiary that reduced the amount available pursuant to this clause
(c) for making Restricted Payments and (y) such payments may be added pursuant
to this clause (iii) only to the extent such payments are not included in the
calculation of Adjusted Consolidated Net Income, provided further that if
Investments of the types specified in clauses (iv) and (v) of the Definition of
"Restricted Payment" have been made in any Person and such Person thereafter
becomes a Restricted Subsidiary, then the aggregate amount of such Investment
(to the extent that they have reduced the amount available pursuant to this
clause (c) for making Restricted Payments), net of the amounts previously added
pursuant to this clause (iii), may be added to the amount available for making
Restricted Payments. The foregoing clause (c) will not prevent the payment of
any dividend within 60 days after the date of its declaration if such dividend
could have been made on the date of its declaration without violation of the
provisions of this covenant.     
   
  None of the Company, any of its Restricted Subsidiaries or any Eligible Joint
Venture will be deemed to have made an Investment at the time that a Person
that is a Restricted Subsidiary of the Company or an Eligible Joint Venture
ceases to be a Restricted Subsidiary or an Eligible Joint Venture (other than
as a result of becoming an Unrestricted Subsidiary), although any subsequent
Investment made by the Company, its Restricted Subsidiaries and Eligible Joint
Ventures in such Person will be Investments that will be subject to the
foregoing paragraph unless and until such time as such Person becomes a
Restricted Subsidiary or an Eligible Joint Venture. Notwithstanding the
foregoing, the designation of a Restricted Subsidiary or an Eligible Joint
Venture as an Unrestricted Subsidiary, as provided in the definition of
"Unrestricted Subsidiary," will be an Investment that will be subject to the
foregoing paragraph.     
 
  Restricted Payments are defined in the Indenture to exclude Permitted
Payments, which include Permitted Investments. See "Certain Definitions" below.

 Limitation on Dividends and Other Payment Restrictions Affecting Subsidiaries
   
  The Company will not, and will not permit any of its Restricted Subsidiaries
or any Eligible Joint Venture to, create or cause to become, or as a result of
the acquisition of any Person or Property, or upon any Person becoming a
Restricted Subsidiary or an Eligible Joint Venture, remain subject to, any
consensual encumbrance or consensual restriction of any kind on the ability of
any Restricted Subsidiary or any Eligible Joint Venture to (a) pay dividends or
make any other distributions permitted by applicable law on any Capital Stock
of such Restricted Subsidiary or such Eligible Joint Venture owned by the
Company, any other Restricted Subsidiary or any other Eligible Joint Venture,
(b) make payments in respect of any Debt owed to the Company, any other
Restricted Subsidiary of the Company or any Eligible Joint Venture, (c) make
loans or advances to the Company or to any other Restricted Subsidiary of the
Company or any other Eligible Joint Venture that is directly or indirectly
owned by such Restricted Subsidiary or such Eligible Joint Venture or (d)
transfer any of its Property to the Company or to any other Restricted
Subsidiary or any other Eligible Joint Venture that directly or indirectly owns
or is owned by such Restricted Subsidiary or such Eligible Joint Venture, other
than those encumbrances and restrictions created or existing (i) on the date of
the original issuance of the Notes, (ii) pursuant to the Indenture, (iii) in
connection with the Incurrence of any Debt permitted under the provisions
described in clause (iii) of the second paragraph of "Limitation on Subsidiary
Debt" above, provided that, in the case of Debt owed to Persons other than the
Company, its Restricted Subsidiaries and any Eligible Joint Venture, the
President or the Chief Financial Officer of the Company determines in good
faith, as evidenced by an Officers' Certificate, that such encumbrances or
restrictions are required to effect such financing and are not materially more
restrictive, taken as a whole, on the ability of the applicable Restricted
Subsidiary or the applicable Eligible Joint Venture to make the payments,
distributions, loans, advances or transfers referred to in clauses (a) through
(d) above than encumbrances and restrictions, taken as a whole, customarily
accepted (or, in the absence of any industry custom, reasonably acceptable) in
comparable financings or comparable transactions in applicable jurisdictions,
(iv) in connection with the execution and delivery of an electric power or
thermal energy purchase contract, or other contract related to the output or
product of, or services rendered by a Permitted Facility, to which such
Restricted Subsidiary or such Eligible Joint Venture is the supplying party or
other contracts with customers, suppliers and contractors to which such
Restricted Subsidiary or such Eligible Joint Venture is a party and where such
Restricted Subsidiary or such Eligible Joint Venture is engaged, directly or
indirectly, in the development, design, engineering, procurement, construction,
acquisition, ownership, management or operation of such Permitted Facility,
provided that the President or the Chief Financial Officer of the Company
determines in good faith, as evidenced by an Officers' Certificate, that such
encumbrances or restrictions are required to effect such contracts and are not
materially more restrictive, taken as a whole, on the ability of the applicable
Restricted Subsidiary or the applicable Eligible Joint Venture to make the
payments, distributions, loans, advances or transfers referred to in clauses
(a) through (d) above than encumbrances and restrictions, taken as a whole,
customarily accepted (or, in the absence of any industry custom, reasonably
acceptable) in comparable financings or comparable transactions in the
applicable jurisdiction, (v) in connection with any Acquired Debt, provided
that such encumbrance or restriction was not incurred in contemplation of such
Person becoming a Restricted Subsidiary or an Eligible Joint Venture and
provided further that such encumbrance or restriction does not extend to any
other Property of such Person at the time it became a Restricted Subsidiary or
an Eligible Joint Venture, (vi) in connection with the Incurrence of any Debt
permitted under clause (iv) of the provision described in the second paragraph
of "Limitation on Subsidiary Debt" above, provided that, in the case of Debt
owed to Persons other than the Company and its Restricted Subsidiaries, the
President or the Chief Financial Officer of the Company determines in good
faith, as evidenced by an Officers' Certificate, that such encumbrances or
restrictions taken as a whole are not materially more restrictive than the
encumbrances and restrictions applicable to the Debt and/or equity being
exchanged or refinanced, (vii) customary non-assignment provisions in leases or
other contracts entered into in the ordinary course of business of the Company,
any Restricted Subsidiary or any Eligible Joint Venture, (viii) any
restrictions imposed pursuant to an agreement entered into for the sale or
disposition of all or substantially all of the Capital Stock or Property of any
Restricted Subsidiary or Joint Venture that apply pending the closing of such
sale or disposition, (ix) in connection with Liens on the     
 
                                       55
<PAGE>
 
Property of such Restricted Subsidiary or such Eligible Joint Venture that are
permitted by the covenant described under "Limitation on Liens" below but only
with respect to transfers referred to in clause (d) above or (x) in connection
with the Incurrence of any Debt permitted under clause (ii) of the provisions
described in the second paragraph of "Limitation on Subsidiary Debt" above.
 
 Limitation on Dispositions
   
  Subject to the covenant described under "Mergers, Consolidations and Sales of
Assets" below, the Company will not make, and will not permit any of its
Restricted Subsidiaries or any Eligible Joint Venture to make, any Asset
Disposition unless (i) the Company, the Restricted Subsidiary or the Eligible
Joint Venture, as the case may be, receives consideration at the time of each
such Asset Disposition at least equal to the fair market value of the Property
or securities sold or otherwise disposed of (to be determined in good faith by
the Chief Financial Officer, as evidenced by an Officers' Certificate, or, if
more than $15 million, by the Board of Directors, as evidenced by a Board
resolution), (ii) at least 85% of such consideration is received in cash or
Cash Equivalents or, if less than 85%, the remainder of such consideration
consists of Property related to the business of the Company as described in the
first sentence of the covenant described under "Limitation on Business" below,
and (iii) unless otherwise required under the terms of Senior Debt, at the
Company's election, the Net Cash Proceeds are either (A) invested in the
business of the Company, any of its Restricted Subsidiaries or any Eligible
Joint Venture or (B) applied to the payment of any Debt of the Company, such
Restricted Subsidiary or such Eligible Joint Venture (or as otherwise required
under the terms of such Debt) (other than Debt owed to the Company, another
Restricted Subsidiary or another Eligible Joint Venture by such Restricted
Subsidiary or such Eligible Joint Venture), provided that, no such payment of
Debt under Permitted Working Capital Facilities or any other revolving credit
agreement will count for this purpose unless the related loan commitment,
standby facility or the like will be permanently reduced by an amount equal to
the principal amount so repaid, provided further that such investment or such
payment, as the case may be, must be made within 365 days from the later of the
date of such Asset Disposition or the receipt by the Company, such Restricted
Subsidiary or such Eligible Joint Venture of the Net Cash Proceeds related
thereto. Any Net Cash Proceeds from Asset Dispositions that are not applied as
provided in clause (A) or (B) of the preceding sentence will constitute "Excess
Proceeds." Excess Proceeds will be applied, as described below, to make an
offer (an "Offer") to purchase Notes at a purchase price equal to 100% of
Accreted Value thereof, plus accrued interest, if any, to the date of purchase.
       
  Notwithstanding anything in the foregoing to the contrary, the Company, its
Restricted Subsidiaries and the Eligible Joint Ventures may exchange with other
Persons (i) Property that constitutes a Restricted Subsidiary or an Eligible
Joint Venture for Property that constitutes a Restricted Subsidiary or an
Eligible Joint Venture, (ii) Property that constitutes a Restricted Subsidiary
or an Eligible Joint Venture for Property that does not constitute a Restricted
Subsidiary or an Eligible Joint Venture, (iii) Property that does not
constitute a Restricted Subsidiary or an Eligible Joint Venture for Property
that does not constitute a Restricted Subsidiary or an Eligible Joint Venture
and (iv) Property that does not constitute a Restricted Subsidiary or an
Eligible Joint Venture for Property that constitutes a Restricted Subsidiary or
an Eligible Joint Venture, provided that in each case the fair market value of
the Property received is at least equal to the fair market value of the
Property exchanged as determined in good faith by the Chief Financial Officer,
as evidenced by an Officers' Certificate, or, if more than $25 million, by the
Board of Directors, as evidenced by a Board resolution, provided that the
Investment in the Property received in the exchanges described in clauses (ii)
and (iii) of the prior sentence will be subject to the covenant described under
"Limitation on Restricted Payments" above. Notwithstanding anything in the
foregoing to the contrary, the Company may not, and will not permit any of its
Restricted Subsidiaries or any Eligible Joint Venture to, make an Asset
Disposition of any of their interest in, or Property of, any of the Coso
Project other than for consideration consisting solely of cash.     
 
  To the extent that any or all of the Net Cash Proceeds of any Foreign Asset
Disposition are prohibited from (or delayed in) being repatriated to the United
States by applicable local law, the portion of such Net Cash Proceeds so
affected will not be required to be applied at the time provided above but may
be retained
 
                                       56
<PAGE>
 
by any Restricted Subsidiary or any Eligible Joint Venture so long, but only so
long, as the applicable local law does not permit (or delays) repatriation to
the United States. If such Net Cash Proceeds are transferred by the Restricted
Subsidiary or Eligible Joint Venture that conducted the Foreign Asset
Disposition to another Restricted Subsidiary or Eligible Joint Venture, the
Restricted Subsidiary or Eligible Joint Venture receiving such Net Cash
Proceeds must not be directly or indirectly obligated on any Debt owed to any
Person other than the Company. The Company will take or cause such Restricted
Subsidiary or such Eligible Joint Venture to take all actions required by the
applicable local law to permit such repatriation promptly. Once repatriation of
any of such Net Cash Proceeds is permitted under the applicable local law,
repatriation will be effected immediately and the repatriated Net Cash Proceeds
will be applied in the manner set forth in this covenant as if such Asset
Disposition had occurred on the date of such repatriation. In addition, if the
Chief Financial Officer determines, in good faith, as evidenced by an Officers'
Certificate, that repatriation of any or all of the Net Cash Proceeds of any
Foreign Asset Disposition would have a material adverse tax consequence to the
Company, the Net Cash Proceeds so affected may be retained outside of the
United States by the applicable Restricted Subsidiary or the applicable
Eligible Joint Venture for so long as such material adverse tax consequence
would continue. Notwithstanding the foregoing provisions of this paragraph to
the contrary, if applicable local law prohibits (or delays) the repatriation of
Net Cash Proceeds of a Foreign Asset Disposition but such local law does not
prohibit the application of such Net Cash Proceeds pursuant to the first
sentence of the first paragraph of this covenant, the Company may apply by such
Net Cash Proceeds pursuant to such provision.
 
  If the Notes tendered pursuant to an Offer have an aggregate purchase price
that is less than the Excess Proceeds available for the purchase of the Notes,
the Company may use the remaining Excess Proceeds for general corporate
purposes without regard to the provisions of this covenant. The Company will
not be required to make an Offer for Notes if the Excess Proceeds available
therefor are less than $10 million, provided, that the lesser amounts of such
Excess Proceeds will be carried forward and cumulated for each 36 consecutive
month period for purposes of determining whether an Offer is required with
respect to any Excess Proceeds of any subsequent Asset Dispositions. Any such
lesser amounts so carried forward and cumulated need not be segregated or
reserved and may be used for general corporate purposes, provided that such use
will not reduce the amount of cumulated Excess Proceeds or relieve the Company
of its obligation hereunder to make an Offer with respect thereto.
 
  The Company will make an Offer by mailing to each Holder, within 30 days from
the receipt of Excess Proceeds that cause the cumulated Excess Proceeds to
exceed $10 million, a written notice that will specify the purchase date, which
will not be less than 30 days nor more than 60 days after the date of such
notice (the "Purchase Date"), and that will contain certain information
concerning the business of the Company that the Company believes in good faith
will enable the Holders to make an informed decision. Holders that elect to
have their Notes purchased will be required to surrender such Notes at least
one Business Day prior to the Purchase Date. If at the expiration of the Offer
period the aggregate purchase price of the Notes tendered by Holders and
purchased pursuant to the Offer exceeds the amount of such Excess Proceeds, the
Notes or portions of Notes to be accepted will be selected by the Trustee in
such manner as the Trustee deems to be fair and appropriate in the
circumstances.
 
  If the Company is prohibited by applicable law from making the Offer or
purchasing Notes thereunder, the Company need not make an Offer for so long as
such prohibition is in effect.
 
  The Company will comply with all applicable tender offer rules, including,
without limitation, Rule 14e-1 under the Exchange Act, in connection with an
Offer.
 
 Limitation on Transactions with Affiliates
 
  The Company will not, and will not permit any of its Restricted Subsidiaries
or any Eligible Joint Venture to, directly or indirectly, conduct any business
or enter into or permit to exist any transaction or series of related
transactions (including, but not limited to, the purchase, sale or exchange of
Property, the
 
                                       57
<PAGE>
 
making of any Investment, the giving of any Guarantee or the rendering of any
service) with any Affiliate of the Company, such Restricted Subsidiary or such
Eligible Joint Venture, as the case may be, unless (i) such business,
transaction or series of related transactions is in the best interest of the
Company, such Restricted Subsidiary or such Eligible Joint Venture, (ii) such
business, transaction or series of related transactions is on terms no less
favorable to the Company or such Restricted Subsidiary, or such Eligible Joint
Venture than those that could be obtained in a comparable arm's length
transaction with a Person that is not such an Affiliate and (iii) (a) with
respect to such business, transaction or series of related transactions that
has a fair market value or involves aggregate payments equal to, or in excess
of, $10 million but less than $25 million, the Company delivers to the Trustee
an Officers' Certificate certifying that, in good faith, it is such officer's
belief that such business, transaction or series of related transactions
complies with clauses (i) and (ii) above, and (b) with respect to such
business, transaction or series of related transactions that has a fair market
value or involves aggregate payments equal to, or in excess of, $25 million
such business, transaction or series of transactions is approved by a majority
of the Board of Directors (including a majority of the disinterested
directors), which approval is set forth in a Board resolution delivered to the
Trustee certifying that, in good faith, the Board of Directors believes that
such business, transaction or series of transactions complies with clauses (i)
and (ii) above.
 
 Limitation on Liens
   
  The Company may not Incur any Debt that is secured, directly or indirectly,
with, and the Company will not, and will not permit any of its Restricted
Subsidiaries or any Eligible Joint Venture to, grant a Lien on the Property of
the Company, its Restricted Subsidiaries or any Eligible Joint Venture now
owned or hereafter acquired unless contemporaneous therewith or prior thereto
the Notes are equally and ratably secured except for (i) any such Debt secured
by Liens existing on the Property of any entity at the time such Property is
acquired by the Company, any of its Restricted Subsidiaries or any Eligible
Joint Venture, whether by merger, consolidation, purchase of such Property or
otherwise, provided that such Liens (x) are not created, incurred or assumed in
contemplation of such Property being acquired by the Company, any of its
Restricted Subsidiaries or any Eligible Joint Venture and (y) do not extend to
any other Property of the Company, any of its Restricted Subsidiaries or any
Eligible Joint Venture, (ii) any other Debt that is required by the terms
thereof to be equally and ratably secured as a result of the Incurrence of Debt
that is permitted to be secured pursuant to another clause of this covenant,
(iii) Liens that are granted in good faith to secure Debt (A) contemplated by
clause (iv) of the covenant described under "Limitation on Debt" above or (B)
contemplated by clauses (ii), (iii) and (vi) of the covenant described under
"Limitation on Subsidiary Debt" above, provided that, in the case of Debt owed
to a Person other than the Company or a Restricted Subsidiary, the President or
Chief Financial Officer of the Company determines in good faith, as evidenced
by an Officers' Certificate, that such Liens are required in order to effect
such financing and are not materially more restrictive, taken as a whole, than
Liens, taken as a whole, customarily accepted (or in the absence of industry
custom, reasonably acceptable) in comparable financings or comparable
transactions in the applicable jurisdiction, (iv) Liens existing on the date of
the original issuance of the Notes, (v) Liens incurred to secure Debt incurred
by the Company as permitted by clause (vi) of the covenant described under
"Limitation on Debt" above, provided that such Liens may not cover any Property
other than that being purchased, (vi) Liens on any Property of the Company
securing Permitted Working Capital Facilities, Guarantees thereof and any
Interest Rate Protection Agreements or Currency Protection Agreements, provided

 Purchase of Notes Upon a Change of Control
 
  Upon the occurrence of a Change of Control, each Holder of the Notes will
have the right to require that the Company repurchase such Holder's Notes at a
purchase price in cash equal to 101% of the Accreted Value thereof on the date
of purchase plus accrued interest, if any, to the date of purchase.
 
  The Change of Control provisions may not be waived by the Trustee or by the
Board of Directors, and any modification thereof must be approved by each
Holder. Nevertheless, the Change of Control provisions will not necessarily
afford protection to Holders, including protection against an adverse effect on
the value of the Notes, in the event that the Company or its Subsidiaries Incur
additional Debt, whether through recapitalizations or otherwise.
   
  Within 30 days following a Change of Control, the Company will mail a notice
to each Holder, with a copy to the Trustee, stating (1) that a Change of
Control has occurred and that such Holder has the right to require the Company
to purchase such Holder's Notes at the purchase price described above (the
"Change of Control Offer"), (2) the circumstances and relevant facts regarding
such Change of Control (including information with respect to pro forma
historical income, cash flow and capitalization after giving effect to such
Change of Control), (3) the purchase date (which will be not earlier than 30
days nor later than 60 days from the date such notice is mailed) (the "Purchase
Date"), (4) that original issue discount on any Note not tendered or purchased
will continue to accrete until January 15, 1997, and thereafter interest on any
such Note will continue to accrue, (5) any Note properly tendered pursuant to
the Change of Control Offer will cease to accrete original issue discount or
accrue interest, as the case may be, after the Purchase Date (assuming
sufficient moneys for the purchase thereof are deposited with the Trustee), (6)
that Holders electing to have a Note purchased pursuant to a Change of Control
Offer will be required to surrender the Note, with the form entitled "Option of
Holder To Elect Purchase" on the reverse of the Note completed, to the paying
agent at the address specified in the notice prior to the close of business on
the Purchase Date, (7) that a Holder will be entitled to withdraw such Holder's
election if the paying agent receives, not later than the close of business on
the third Business Day (or such shorter periods as may be required by
applicable law) preceding the Repurchase Date, a telegram, telex, facsimile
transmission or letter setting forth the name of the Holder, the principal
amount of Notes the Holder delivered for purchase, and a statement that such
Holder is withdrawing his election to have such Notes purchased and (8) that
Holders that elect to have their Notes purchased only in part will be issued
new Notes having a principal amount equal to the portion of the Notes that were
surrendered but not tendered and purchased.     
 
  On the Purchase Date, the Company will (i) accept for payment all Notes or
portions thereof tendered pursuant to the Change of Control Offer, (ii) deposit
with the Trustee money sufficient to pay the purchase
 
                                       59
<PAGE>
 
price of all Notes or portions thereof so tendered for purchase and (iii)
deliver or cause to be delivered to the Trustee the Notes properly tendered
together with an Officers' Certificate identifying the Notes or portions
thereof tendered to the Company for purchase. The Trustee will promptly mail to
the Holders of the Notes properly tendered payment in an amount equal to the
purchase price, and promptly authenticate and mail to each Holder a new Note
having a principal amount equal to any portion of such Holder's Notes that were
surrendered but not tendered and purchased, the Company will publicly announce
the results of the Change of Control Offer on or as soon as practicable after
the Purchase Date.
 
  If the Company is prohibited by applicable law from making the Change of
Control Offer or purchasing Notes thereunder, the Company need not make a
Change of Control Offer for so long as such prohibition is in effect.
 
  The Company will comply with all applicable tender offer rules, including,
without limitation, Rule 14e-1 under the Exchange Act, in connection with a
Change of Control Offer.
 
 Limitation on Business
 
  The Company will, and will cause its Restricted Subsidiaries and the Eligible
Joint Ventures to, engage only in (i) the ownership, design, engineering,
procurement, construction, development, acquisition, operation, servicing,
management or disposition of Permitted Facilities, (ii) the ownership,
creation, development, acquisition, servicing, management or disposition of
Restricted Subsidiaries and Joint Ventures that own, construct, develop,

Restricted Subsidiaries or any Eligible Joint Venture to, make any Investment

of the Company as described in the preceding sentence (collectively, the
"Ineligible Investments") other than as a part of an Investment or an
acquisition of Property that is predominantly directly related to the business
of the Company as described above, and if the aggregate fair market value of
such Ineligible Investments in the aggregate exceeds 10% (the "10% Limit") of
the total assets of the Company and its consolidated Restricted Subsidiaries
(as determined in accordance with GAAP) as determined in good faith by the
Chief Financial Officer, as evidenced by an Officers' Certificate, the Company,
its Restricted Subsidiaries and the Eligible Joint Ventures must cease
acquiring any additional Ineligible Investments and, within 18 months of the
acquisition that caused the Ineligible Assets to exceed the 10% Limit, must
return to compliance with the 10% Limit by disposing of Ineligible Assets or
otherwise, provided that such 18-month period may be extended up to an
additional six months if, despite the Company's active efforts during such 18-
month period to dispose of such Ineligible Investments or to otherwise come
into compliance with such 10% Limit, the Company is unable to do so because of
regulatory restrictions or delays or adverse market conditions.
 
 Limitation on Certain Sale-Leasebacks
 
  The Company will not, and will not permit any of its Restricted Subsidiaries
or any Eligible Joint Venture to, Incur or otherwise become obligated with
respect to any sale-leaseback (other than a sale-leaseback with respect to a
Permitted Facility that is Non-Recourse) unless, (i) (a) if effected by the
Company, the Company would be permitted to Incur such obligation under the
covenant described under "Limitation on Debt" above or, (b) if effected by a
Restricted Subsidiary or an Eligible Joint Venture, such Restricted Subsidiary
or such Eligible Joint Venture would be permitted to Incur such obligation

"Limitation on Debt" and "Limitation on Subsidiary Debt" that (x) the
obligation created by such sale-leaseback is a Capitalized Lease and (y) the
Capitalized Lease Obligation with respect thereto is the Attributable Value
thereof, (ii) the Company, such Restricted Subsidiary or such Eligible Joint
Venture is permitted to grant a Lien with respect to the property that is the
subject of such sale-leaseback under the covenant described under "Limitation
on Liens" above, (iii) the proceeds of such sale-leaseback
 
                                       60
<PAGE>
 
are at least equal to the fair market value of the property sold (determined in
good faith by the Board of Directors, as evidenced by a Board resolution) and
(iv) the Net Cash Proceeds of the sale-leaseback are applied pursuant to the
covenants described under "Limitation on Dispositions" above.

the Company or an Eligible Joint Venture, (iii) Preferred Stock issued by a
Person prior to the time (a) such Person becomes a Restricted Subsidiary or an
Eligible Joint Venture, (b) such Person merges with or into another Restricted
Subsidiary or another Eligible Joint Venture or (c) a Restricted Subsidiary or

such Person becoming a Restricted Subsidiary or an Eligible Joint Venture or of
such merger, (iv) Preferred Stock issued or agreed to be issued by a Restricted
Subsidiary or an Eligible Joint Venture in connection with the financing of the
construction, design, engineering, procurement, equipping, developing,

Facility or in order to enhance the repatriation of equity, advances or income
or the increase of after-tax funds available for distribution to the owners of
such Permitted Facility, (v) Preferred Stock issued or agreed to be issued by a
Restricted Subsidiary or an Eligible Joint Venture in satisfaction of legal
requirements applicable to a Permitted Facility or to maintain the ordinary

substantially all its Property (as an entirety or substantially an entirety in
one transaction or a series of related transactions), to any Person unless: (i)
the Company will be the continuing Person, or the Person (if other than the
Company) formed by such consolidation or into which the Company is merged or to
which the Property of the Company is transferred will be a corporation
organized and existing under the laws of the United States or any State thereof

MODIFICATION OF THE INDENTURE
 
  The Indenture contains provisions permitting the Company and the Trustee,
with the consent of the Holders of not less than a majority in principal amount
of the Notes at the time outstanding, to modify the Indenture or any
supplemental indenture or the rights of the Holders of the Notes, except that
no such modification may (i) extend the final maturity of any of the Notes,
reduce the principal amount, thereof, reduce the rate or extend the time of
accretion of original issue discount thereon beyond January 15, 1997 or the
time of payment of any cash interest thereon, reduce any amount payable on
redemption or purchase thereof or impair the right of any Holder to institute
suit for the payment thereof or make any change in the covenants regarding a
Change of Control or an Asset Disposition or the related definitions without
the consent of the Holder of each of the Notes so affected or (ii) reduce the
percentage of Notes, the consent of the Holders of which is required for any
such modification, without the consent of the Holders of all Notes then
outstanding.
 
EVENTS OF DEFAULT
   
  An Event of Default is defined in the Indenture as being: (i) default as to
the payment of principal, or premium, if any, on any Note or as to any payment
required in connection with a Change of Control or an Asset Disposition, (ii)
default as to the payment of interest on any Note for 30 days after payment is
due, (iii) default on any other Debt of the Company or any Significant
Subsidiary (other than Non-Recourse Debt of Significant Subsidiaries) if either
(x) such default results from failure to pay principal of such Debt in excess
of $25 million when due after any applicable grace period or (y) as a result of
such default, the maturity of such Debt has been accelerated prior to its
scheduled maturity and such default has not been cured within the applicable
grace period, and such acceleration has not been rescinded, and the principal
amount of such Debt, together with the principal amount of any other Debt of
the Company and its Significant Subsidiaries (not including Non-Recourse Debt
of the Significant Subsidiaries) that is in default as to principal, or the
maturity of which has been accelerated, aggregates $25 million or more, (iv)
default in the performance, or breach, of any covenant, agreement or warranty
contained in the Indenture and the Notes and such failure continues for 30 days
after written notice is given to the Company by the Trustee or the Holders of
at least 25% in principal amount of the outstanding Notes, as provided in the
Indenture, (v) the entry by a court of one or more judgments or orders against
the Company or any Significant Subsidiary for the payment of money that in the
aggregate exceeds $25 million (excluding the amount thereof covered by
insurance or by a bond written by a Person other than an Affiliate of the
Company), which judgments or orders have not been vacated, discharged or
satisfied or stayed pending appeal within 60 days from the entry thereof,
provided, that such a judgment or order will not be an Event of Default if such
judgment or order does not require any payment by the Company or any
Significant Subsidiary, except to the extent that such judgment is only against
Property that secures Non-Recourse Debt that was permitted under the Indenture,
and the Company could, at the expiration of the applicable 60 day period, after
giving effect to such judgment or order and the consequences thereof, Incur at
least $1 of Debt under the provision described in the first paragraph of
"Limitation on Debt" above, and (vi) certain events involving bankruptcy,
insolvency or reorganization of the Company or any of its Significant
Subsidiaries.     
 
  The Indenture provides that the Trustee may withhold notice to the Holders of
any default (except in payment of principal of, premium, if any, on the Notes
and any payment required in connection with a Change of Control or an Asset
Disposition) if the Trustee considers it in the interest of Holders to do so.
 
  The Indenture provides that if an Event of Default (other than an event of
bankruptcy, insolvency or reorganization of the Company or a Significant
Subsidiary) has occurred and is continuing, either the Trustee or the Holders
of not less than 25% in principal amount of the Notes then outstanding may
declare the Default Amount of all Notes to be due and payable immediately, but
upon certain conditions such declaration may be annulled and past defaults
(except, unless theretofore cured, a default in payment of principal of,
premium, if any, or interest on the Notes or any payment required in connection
with a Change of Control or an Asset Disposition, as the case may be) may be
waived by the Holders of a majority in principal amount
 
                                       62
<PAGE>
 
of the Notes then outstanding. If an Event of Default due to the bankruptcy,
insolvency or reorganization of the Company or a Significant Subsidiary occurs,
the Indenture provides that the Default Amount of all Notes will become
immediately due and payable.
   
  The Holders of a majority in principal amount of the Notes then outstanding
will have the right to direct the time, method and place of conducting any
proceeding for any remedy available to the Trustee under the Indenture, subject
to certain limitations specified in the Indenture, provided that the Holders of
Notes must have offered to the Trustee reasonable indemnity against expenses
and liabilities. The Indenture requires the annual filing by the Company with
the Trustee of a written statement as to compliance with the principal
covenants contained in the Indenture.     
 
DEFEASANCE
 
 Legal Defeasance
   
  The Indenture provides that the Company will be deemed to have paid and will
be discharged from any and all obligations in respect of the Notes, on the
123rd day after the deposit referred to below has been made (or immediately if
an Opinion of Counsel is delivered to the effect described in clause (B)(ii)(y)
below), and the provisions of the Indenture will cease to be applicable with
respect to the Notes (except for, among other matters, certain obligations to
register the transfer or exchange of the Notes, to replace stolen, lost or
mutilated Notes, to maintain paying agencies and to hold monies for payment in
trust) if, among other things, (A) the Company has deposited with the Trustee,
in trust, money and/or U.S. Government Obligations that through the payment of
interest and principal in respect thereof in accordance with their terms will
provide money in an amount sufficient to pay the principal of, premium, if any,
and accrued interest on the Notes, on the Stated Maturity of the Notes or, if
the Company makes arrangements satisfactory to the Trustee for the redemption
of the Notes prior to their Stated Maturity, on any earlier redemption date in
accordance with the terms of the Indenture and the Notes, (B) the Company has
delivered to the Trustee (i) either (x) an Opinion of Counsel to the effect
that Holders will not recognize income, gain or loss for federal income tax
purposes as a result of such deposit, defeasance and discharge and will be
subject to federal income tax on the same amount and in the same manner and at
the same times as would have been the case if such deposit, defeasance and
discharge had not occurred and the Company had paid or redeemed such Notes on
the applicable dates, which Opinion of Counsel must be based upon a ruling of
the Internal Revenue Service to the same effect or a change in applicable
federal income tax law or related Treasury regulations after the date of the
Indenture or (y) a ruling directed to the Trustee received from the Internal
Revenue Service to the same effect as the aforementioned Opinion of Counsel,
(ii) an Opinion of Counsel to the effect that the creation of the defeasance
trust does not violate the Investment Company Act of 1940 and (iii) an Opinion
of Counsel to the effect that either (x) after the passage of 123 days
following the deposit, the trust fund will not be subject to the effect of
Section 547 or 548 of the U.S. Bankruptcy Code or Section 15 of the New York
Debtor and Creditor Law or (y) based upon existing precedents, if the matter
were properly briefed, a court should hold that the deposit of moneys and/or
U.S. Government Obligations as provided in clause (A) would not constitute a
preference voidable under Section 547 or 548 of the U.S. Bankruptcy Code or
Section 15 of the New York Debtor and Creditor Law, (C) immediately after
giving effect to such deposit on a pro forma basis, no Event of Default, or
event that after the giving of notice or lapse of time or both would become an
Event of Default, will have occurred and be continuing on the date of such
deposit or (unless an Opinion of Counsel is delivered to the effect described
in clause (B)(ii)(y) above) during the period ending on the 123rd day after the
date of such deposit, and the deposit will not result in a breach or violation
of, or constitute a default under, any other agreement or instrument to which
the Company is a party or by which the Company is bound and (D) if at such time
the Notes are listed on a national securities exchange, the Company has
delivered to the Trustee an Opinion of Counsel to the effect that the Notes
will not be delisted as a result of such deposit, defeasance and discharge.
    
                                       63
<PAGE>
 
 Covenant Defeasance
   
  The Indenture further provides that the provisions of clause (iii) under
"Mergers, Consolidations and Sales of Assets" and all the covenants described
herein under "Certain Covenants," clause (iv) under "Events of Default" with
respect to such covenants and with respect to clause (iii) under "Mergers,
Consolidations and Sales of Assets," and clauses (iii) and (v) under "Events of
Default" will cease to be applicable to the Company and its Subsidiaries upon
the satisfaction of the provisions described in clauses (A), (B)(ii) and (iii),
(C) and (D) of the preceding paragraph and the delivery by the Company to the
Trustee of an Opinion of Counsel to the effect that, among other things, the
Holders of the Notes will not recognize income, gain or loss for federal income
tax purposes as a result of such deposit and the defeasance of certain
covenants and Events of Default and will be subject to federal income tax on
the same amount and in the same manner and at the same times as would have been
the case if such deposit and defeasance had not occurred and the Company had
paid or redeemed such Notes on the applicable dates.     
 
 Defeasance and Certain Other Events of Default
 
  If the Company exercises its option to omit compliance with certain covenants
and provisions of the Indenture with respect to the Notes as described in the
immediately preceding paragraph and the Notes are declared due and payable
because of the occurrence of an Event of Default that remains applicable, the
amount of money and/or U.S. Government Obligations on deposit with the Trustee
will be sufficient to pay amounts due on the Notes at the time of their Stated
Maturity or scheduled redemption, but may not be sufficient to pay amounts due
on the Notes at the time of acceleration resulting from such Event of Default.
The Company will remain liable for such payments.
 
THE TRUSTEE
 
  IBJ Schroder Bank & Trust Company is the Trustee under the Indenture.
 
GOVERNING LAW
 
  The Indenture and the Notes will be governed by, and construed in accordance
with, the law of the State of New York, including Section 5-1401 of the New
York General Obligations Law, but otherwise without regard to conflict of laws
rules.

                   CERTAIN FEDERAL INCOME TAX CONSIDERATIONS
 
GENERAL
 
  The following is a summary, based on the opinion of Willkie Farr & Gallagher,
counsel to the Company, of the anticipated material United States federal
income tax consequences of the purchase, ownership and disposition of the
Notes. This summary is based upon the Internal Revenue Code of 1986, as amended
(the "Code"), its legislative history, existing and proposed regulations
thereunder, published rulings and court decisions, all as in effect and
existing on the date of this Prospectus and all of which are subject to change
at any time, which change may be retroactive. In particular, the discussion
below of "Original Issue Discount" is based in part on proposed regulations
released on December 22, 1992, but not yet effective (the "Proposed OID
Regulations"). While the 1992 Proposed OID Regulations are proposed to be
effective for debt instruments issued sixty or more days after final
regulations are issued and therefore may not be applicable to the Notes, the
1992 Proposed OID Regulations are the most current indication of the views of
the Internal Revenue Service (the "Service") with respect to the federal income
tax treatment of debt instruments having original issue discount ("OID").
 
  Unless otherwise specified, the discussion below assumes that the rules set
forth in the Proposed OID Regulations will control the tax treatment of the
Notes. However, changes may be made to the Proposed OID Regulations or final
OID regulations may be adopted that would apply to the Notes and that may be
contrary to the interpretations of the Proposed OID Regulations discussed
below. Because of the lack of definitive regulatory authority, no assurance can
be given that the Service will agree with the interpretations of the Proposed
OID Regulations discussed below or that the final OID regulations will not
differ materially from the Proposed OID Regulations or subsequent versions
thereof.
 
  This summary applies only to those persons who are the initial Holders of the
Notes and who hold Notes as capital assets and does not address the tax
consequences to taxpayers who are subject to special rules (such as financial
institutions, tax-exempt organizations and insurance companies) or aspects of
federal income taxation that may be relevant to a prospective investor based
upon such investor's particular tax situation. Accordingly, purchasers of Notes
should consult their own tax advisors with respect to the particular
consequences to them of the purchase, ownership and disposition of the Notes,
including the applicability of any state, local or foreign tax laws to which
they may be subject as well as with respect to the possible effects of changes
in federal and other tax laws.

ORIGINAL ISSUE DISCOUNT
 
  General. Because the Notes are being issued at a discount from their "stated
redemption price at maturity," the Notes will have OID for federal income tax
purposes. For federal income tax purposes, OID on a Note will be the excess of
the stated redemption price at maturity of the Note over its issue price.
Because the Notes will be treated as being publicly offered under the Proposed
OID Regulations, the issue price of the Notes will be the first price to the
public (excluding bond houses and brokers) at which a substantial amount of
Notes is sold.
   
  The stated redemption price at maturity of a Note will be the sum of all
payments to be made on such Note other than "qualified stated interest"
payments. Qualified stated interest is stated interest that is unconditionally
payable at least annually at a single fixed rate that appropriately takes into
account the length of the interval between payments. As cash interest payments
on the Notes will not commence prior to July 15, 1997, the interest payments on
the Notes will not constitute qualified stated interest and thus will be
included along with principal in the stated redemption price at maturity of the
Notes. As a result, each Note will bear OID in an amount equal to the excess of
(i) the sum of its principal amount and all stated interest payments over (ii)
its issue price.     
 
  A Holder will be required to include OID in income periodically over the term
of a Note before receipt of the cash or other payment attributable to such
income. In general, a Holder must include in gross income for federal income
tax purposes the sum of the daily portions of OID with respect to the Note for
each day during the taxable year or portion of a taxable year on which such
Holder holds the Note ("Accrued OID"). The daily portion is determined by
allocating to each day of any accrual period within a taxable year a pro rata
portion of an amount equal to the adjusted issue price of the Note at the
beginning of the accrual period multiplied by the yield to maturity of the
Note. For purposes of computing OID, the Company will use six-month accrual
periods that end on the days in the calendar year corresponding to the maturity
date of the Notes and the date six months prior to such maturity date, with the
exception of an initial short accrual period. The adjusted issue price of a
Note at the beginning of any accrual period is the issue price of the Note
increased by the Accrued OID for all prior accrual periods (less any cash
payments on the Notes). Under these rules, Holders may have to include in gross
income increasingly greater amounts of OID in each successive accrual period.
 
  Optional Redemption. If the Company exercises its rights to redeem the Notes
(See "Description of the Notes--Optional Redemption"), the tax treatment of the
redemption would be governed by the rules for dispositions generally. See
"Disposition of the Notes." However, if the Company were found to have an
intention at the time the Notes were issued to redeem them before maturity, any
taxable income arising from such redemption would be treated as ordinary income
to the extent of any unamortized OID.
   
  If a Holder tenders Notes for redemption as a result of a Change of Control
(See "Description of the Notes--Certain Covenants--Repurchase of Notes Upon a
Change of Control"), the Holder may be required to include as ordinary income
any amount the Holder is entitled to receive in excess of the Accreted Value of
a Note on the date of the redemption. Holders should consult their own tax
advisors regarding the treatment of payments upon optional redemptions.     
 
DISPOSITION OF THE NOTES
 
  Generally, any sale or redemption of the Notes will result in taxable gain or
loss equal to the difference between the amount of cash or other property
received and the Holder's adjusted tax basis in the Note. A Holder's adjusted
tax basis for determining gain or loss on the sale or other disposition of a
Note will initially equal the cost of the Note to such Holder and will be
increased by any Accrued OID (and, as described below, any market discount)
includible in such Holder's gross income and decreased by the amount of any
cash payments received by such Holder regardless of whether such payments are
denominated as principal or interest. Except to the extent that the market
discount rules described below apply, any gain or loss upon a sale or other
disposition of a Note will generally be capital gain or loss, which will be
long term if the Note has been held by the Holder for more than one year.
 
                                       82
<PAGE>
 
  Market Discount. Generally, market discount will exist to the extent the
purchase price paid by a Holder for a Note is less than the issue price of the
Note at the time of purchase, subject to a statutory de minimis exception.
Generally, a Holder of a Note who acquires the Note with market discount will
be required to treat any gain realized upon the disposition of such Note as
ordinary income to the extent of the market discount that accrued (but was not
previously included in income) during the period such Holder held the Note.
Furthermore, the Code requires that partial principal payments on a market
discount bond be included in gross income to the extent that such payments do
not exceed the accrued market discount on such bond. Thus, if a cash payment is
received by a Holder, such Holder will be required to include in income at the
time such cash payment is received the portion of the unrecognized market
discount that accrued prior to the receipt of such cash payment (up to the
amount of such payment). A Holder of a Note who has acquired the Note with
market discount may also be required to defer deduction of a portion of
interest on debt incurred or continued to purchase or carry the Note until
disposition of the Note in a taxable transaction.
 
  A Holder may elect to include market discount in income as such discount
accrues with a corresponding increase in the Holder's tax basis in the Note. If
a Holder so elects, the rules in the preceding paragraph regarding the
treatment of income or gain upon the disposition of a Note and upon receipt of
certain cash payments as ordinary income or gain, and regarding the deferral of
interest deductions on indebtedness related to a Note, would not apply. Once
made, such an election applies to all debt obligations that are purchased by
the Holder at a market discount during the taxable year for which the election
is made, and all subsequent taxable years of the Holder, unless the Service
consents to a revocation of the election.
 
  Acquisition Premium. A Holder of a Note who acquires such Note at a cost in
excess of its issue price will be considered to have purchased such Note at an
"acquisition premium." Under the acquisition premium rules contained in the
Code, generally, such Holder would be entitled to a reduction in the amount of
OID otherwise includible in income with respect to such Note.
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES TO THE COMPANY AND TO CORPORATE HOLDERS
 
  The Notes will constitute "applicable high yield discount obligations"
("AHYDOs") if the yield to maturity of such Notes is equal to or greater than
the sum of the relevant applicable federal rate (the "AFR"), plus five
percentage points. The AFR applicable to the Notes is   %, compounded
semiannually. Accordingly, if the yield to maturity of the Notes is equal to or
greater than   %, the Notes will constitute AHYDOs. If the Notes are AHYDOs, as
described below, a portion of the tax deductions that would otherwise be
available to the Company in respect of the Notes will be deferred or
disallowed, which, in turn, might reduce the after-tax cash flows of the
Company. More particularly, if the Notes constitute AHYDOs, the Company will
not be entitled to deduct OID that accrues with respect to such Notes until
amounts attributable to OID are paid in cash. In addition, if the yield to
maturity of the Notes exceeds the sum of the relevant AFR plus six percentage
points (the "Excess Yield"), the "disqualified portion" of the OID accruing on
the Note will be characterized as a non-deductible dividend with respect to the
Company and also may be treated as a dividend distribution solely for purposes
of the dividends received deduction of Sections 243, 246 and 246A of the Code
with respect to Holders that are U.S. corporations.
 
  In general, the "disqualified portion" of OID for any accrual period will be
equal to the product of (i) a percentage determined by dividing the Excess
Yield by the yield to maturity and (ii) the OID for the accrual period. Subject
to otherwise applicable limitations, such a corporate Holder will be entitled
to a dividends received deduction (generally at a 70% rate) with respect to the
disqualified portion of the Accrued OID if the Company has sufficient current
or accumulated "earnings and profits." To the extent that the Company's
earnings and profits are insufficient, any portion of the OID that otherwise
would have been recharacterized as a dividend for purposes of the dividends
received deduction will continue to be taxed as ordinary OID income in
accordance with the rules described above in "Original Issue Discount."
Treatment of the Notes as AHYDOs will not disqualify interest or OID with
respect to the Notes from the portfolio interest exception described below
under "Foreign Holders," provided all applicable requirements for the exception
are otherwise satisfied.
 
                                       83
<PAGE>
 
BACKUP WITHHOLDING
 
  A Holder may be subject, under certain circumstances, to backup withholding
at a 31 percent rate with respect to payments received with respect to the
Notes. This withholding generally applies only if the Holder (i) fails to
furnish his or her social security or other taxpayer identification number
("TIN"), (ii) furnishes an incorrect TIN, (iii) is notified by the Service that
he or she has failed to report properly payments of interest or dividends and
the Service has notified the Company that he or she is subject to backup
withholding, or (iv) fails, under certain circumstances, to provide a certified
statement, signed under penalty of perjury, that the TIN provided is his or her
correct number and that he or she is not subject to backup withholding. Any
amount withheld from a payment to a Holder under the backup withholding rules
is allowable as a credit against such Holder's Federal income tax liability,
provided that the required information is furnished to the Service. Certain
Holders (including, among others, corporations and foreign individuals who
comply with certain certification requirements described below under "Foreign
Holders") are not subject to backup withholding. Holders should consult their
tax advisors as to their qualification for exemption from backup withholding
and the procedure for obtaining such an exemption.
 
FOREIGN HOLDERS
 
  The following discussion is a summary of certain United States federal income
tax consequences to a Foreign Person that holds a Note. The term "Foreign
Person" means a Holder that is not (i) an individual who is a citizen or
resident of the United States, (ii) a corporation or partnership created or
organized in the United States or under the law of the United States or any
state or (iii) an estate or trust, the income of which is includable in gross
income for United States federal income tax purposes regardless of its source,
but only if the income or gain on the Note is not effectively connected with
the conduct of a trade or business within the United States by such Holder. If
the income or gain on the Note is effectively connected with the conduct of a
trade or business within the United States, then the nonresident alien
individual or foreign corporation will be subject to tax on such income or gain
in essentially the same manner as a U.S. citizen or resident or a domestic
corporation, as discussed above, and in the case of a foreign corporation, may
also be subject to the branch profits tax (unless such branch profits tax is
reduced or eliminated under an applicable treaty).
 
  Under the "portfolio interest" exception to the general rules for the
withholding of tax on interest and OID paid to a Foreign Person, a Foreign
Person will not be subject to U.S. tax (or to withholding) on interest or OID
on a Note, provided that (i) the Foreign Person 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 and is not a controlled
foreign corporation with respect to the United States that is related to the
Company through stock ownership, and (ii) the Company, its paying agent or the
person who would otherwise be required to withhold tax receives either (A) a
statement (an "Owner's Statement") signed under penalties of perjury by the
beneficial owner of the Note in which the owner certifies that the owner is not
a U.S. person and which provides the owner's name and address, or (B) a
statement signed under penalties of perjury by the Financial Institution
holding the Note on behalf of the beneficial owner, together with a copy of the
Owner's Statement. The term "Financial Institution" means a securities clearing
organization, bank or other financial institution that holds customers'
securities in the ordinary course of its trade or business and that holds a
Note on behalf of the owner of the Note. A Foreign Person who does not qualify
for the "portfolio interest" exception would, under current law, generally be
subject to U.S. withholding tax at a flat rate of 30% (or a lower applicable
treaty rate) on interest payments and payments (including redemption proceeds)
attributable to OID on the Notes.
 
  In general, gain recognized by a Foreign Person upon the redemption, sale or
exchange of a Note (including any gain representing accrued market discount)
will not be subject to U.S. tax. However, a Foreign Person may be subject to
U.S. tax at a flat rate of 30% (unless exempt by an applicable treaty) on any
such gain if the Foreign Person is an individual present in the United States
for 183 days or more during the taxable year in which the Note is redeemed,
sold or exchanged, and certain other requirements are met.

  The Underwriting Agreement provides that the obligations of the Underwriters
to purchase the Notes are subject to the approval of certain legal matters by
their counsel and certain other conditions, and that if any of the Notes are
purchased by the Underwriters pursuant to the Underwriting Agreement, all of
the Notes agreed to be purchased by the Underwriters pursuant to the
Underwriting Agreement must be so purchased.
 
  The Company has been advised that the Underwriters propose to offer the Notes
initially at the public offering price set forth on the cover page of this
Prospectus plus accrued original issue discount, if any, to the date of
delivery and to certain selected dealers (who may include Underwriters) at such
public offering price less a selling concession not to exceed    % of the
principal amount of the Notes. The selected dealers may reallow a concession to
certain other dealers not to exceed    % of the principal amount of the Notes.
After the initial public offering of the Notes, the public offering price, the
concession to selected dealers and the reallowance to other dealers may be
changed by the Underwriters.
   
  The Company intends to apply to list the Notes for trading on the New York
Stock Exchange. There can be no assurance that the Notes will be approved for
listing on such exchange or, if listed, that an active trading market for the
Notes will develop or be sustained. The Company has been advised by each
Underwriter that it presently intends to make a market in the Notes; however,
the Underwriters are not obliged to do so. Any such market-making activity may
be discontinued at any time, for any reason, without notice. If each
Underwriter ceases to act as a market maker for the Notes for any reason, there
can be no assurance that another firm or person will make a market in the
Notes. There can be no assurance that an active market for the Notes will
develop or, if a market does develop, at what price the Notes will trade.     
   
  Certain of the Underwriters have provided from time to time, and expect to
provide in the future, investment banking services to the Company and its
affiliates, for which such Underwriters have received and will receive
customary fees.     
 
  The Underwriting Agreement provides that the Company will indemnify the
Underwriters against certain liabilities and expenses, including liabilities
under the Securities Act or contribute to payments the Underwriters may be
required to make in respect thereof.
 
                                 LEGAL MATTERS

connection with the Offering are being passed upon for the Company by Steven A.
McArthur, Senior Vice President and General Counsel of the Company, and by
Willkie Farr & Gallagher, New York, New York. Certain legal matters in
connection with the Offering are being passed upon for the Underwriters by
Skadden, Arps, Slate, Meagher & Flom, New York, New York.

  The financial statements as of December 31, 1992 and 1993 and for each of the
three years in the period ended December 31, 1993 included in this Prospectus
and the related financial statement schedules included elsewhere in the
Registration Statement have been audited by Deloitte & Touche, independent
auditors, as stated in their reports appearing herein and elsewhere in the
Registration Statement, and have been so included in reliance upon the reports
of such firm given upon their authority as experts in accounting and auditing.
 
  With respect to the unaudited interim financial information for the periods
ended March 31, 1992 and 1993, and June 30, 1992 and 1993, and September 30,
1992 and 1993 which is incorporated herein by reference, Deloitte & Touche have
applied limited procedures in accordance with professional standards for a
review of such information. However, as stated in their reports included in the
Company's Quarterly Reports on Form 10-Q for the quarters ended March 31, 1993,
June 30, 1993 and September 30, 1993 and incorporated by reference herein, they
did not audit and they do not express an opinion on that interim financial
information. Accordingly, the degree of reliance on their reports on such
information should be restricted in light of the limited nature of the review
procedures applied. Deloitte & Touche are not subject to the liability
provisions of Section 11 of the Securities Act for their reports on the
unaudited interim financial information because those reports are not "reports"
or a "part" of the Registration Statement prepared or certified by an
accountant within the meaning of Sections 7 and 11 of the Securities Act.

                          INDEPENDENT AUDITORS' REPORT
 
Board of Directors and Shareholders
California Energy Company, Inc.
Omaha, Nebraska
 
  We have audited the accompanying consolidated balance sheets of California
Energy Company, Inc. and subsidiaries as of December 31, 1993 and 1992, and the
related consolidated statements of operations, stockholders' equity and cash
flows for each of the three years in the period ended December 31, 1993. These
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, such consolidated financial statements present fairly, in all
material respects, the financial position of California Energy Company, Inc.
and subsidiaries at December 31, 1993 and 1992 and the results of their
operations and their cash flows for each of the three years in the period ended
December 31, 1993, in conformity with generally accepted accounting principles.
 
  As discussed in Note 8, the consolidated financial statements give effect to
the Company's adoption, effective January 1, 1993, of Statement of Financial
Accounting Standards No. 109, "Accounting for Income Taxes".

1. BUSINESS
   
  California Energy Company, Inc. (the Company) was formed in 1971. It is
primarily engaged in the exploration for and development of geothermal
resources and conversion of such resources into electrical power and steam for
sale to electric utilities, and the development of other environmentally
responsible forms of power generation.     
   
  The Company has organized several partnerships and joint ventures (herein
referred to as Coso Joint Ventures) in order to develop geothermal energy at
the China Lake Naval Air Weapons Station, Coso Hot Springs, China Lake,
California. Collectively, the projects undertaken by the Coso Joint Ventures
are referred to as the Coso Project. The Company is the operator and holds
interests between 46.4% and 50.0% in the Coso Joint Ventures after payout.
Payout is achieved when a Coso Joint Venture has returned the initial capital
to the Coso Joint Venturers. In addition, the Company is exploring geothermal
resources in Northern California, Washington and Oregon (collectively the
Pacific Northwest). In January 1991, the Company acquired a power plant and an
interest in steam fields in Nevada and Utah (See Note 4--Nevada and Utah
Properties). In 1992, the Company entered into the natural gas-fired electrical
generation market through the purchase of a development opportunity in Yuma,
Arizona. Commercial operation of the Yuma project will commence in 1994. In
1993, the Company started developing a number of international power project
opportunities where private power generating programs have been initiated,
including the Philippines and Indonesia.     
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
   
  The consolidated financial statements include the accounts of the Company,
its wholly-owned subsidiaries, and its proportionate share of the Coso Joint
Ventures in which it has invested. All significant inter-enterprise
transactions and accounts have been eliminated.     
 
 Investments and Restricted Cash
 
  Investments other than restricted cash are primarily commercial paper and
money market securities. The restricted cash balance includes such securities
and mortgage backed securities, and is mainly composed of the Coso Joint
Ventures' debt service reserve funds. The debt service reserve funds are
legally restricted to their use and require the maintenance of specific minimum
balances. The carrying amount of the investments approximates the fair value
based on quoted market prices as provided by the financial institution which
holds the investments.
 
 Well, Resource Development and Exploration Costs
   
  The Company follows the full cost method of accounting for costs incurred in
connection with the exploration and development of geothermal resources. All
such costs, which include dry hole costs and the cost of drilling and equipping
production wells, as well as directly attributable administrative and interest
costs, are capitalized and amortized over their estimated useful lives when
production commences. The estimated useful lives of production wells are ten
years each; exploration costs and development costs, other than production
wells, are generally amortized over the weighted average remaining term of the
Company's power and steam purchase contracts. For purposes of current period
visibility and disclosure, all such costs are identified in the Consolidated
Statements of Cash Flows as they are incurred.     
 
 Deferred Well and Rework Costs
 
  Well rework costs are deferred and amortized over the estimated period
between reworks. These deferred costs of $1,305 and $1,592 at December 31, 1993
and 1992, respectively are included in other assets. Currently, both production
and injection well reworks are amortized over twelve months.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
                  FOR THE THREE YEARS ENDED DECEMBER 31, 1993
          (DOLLARS AND SHARES IN THOUSANDS, EXCEPT PER SHARE AMOUNTS)
 
 Fixed Assets and Depreciation
 
  The cost of major additions and betterments are capitalized, while
replacements, maintenance and repairs that do not improve or extend the lives
of the respective assets are expensed.
 
  Depreciation of the operating power plants is computed on the straight-line
method over the estimated useful lives resulting in a composite rate of
depreciation of approximately 2.67% per annum. Depreciation of furniture,
fixtures and equipment, which are recorded at cost, is computed on the
straight-line method over the estimated useful lives of the related assets,
which range from three to ten years.
 
 Capitalization of Interest and Deferred Financing Costs
 
  Prior to the commencement of operations, interest is capitalized on the costs
of the plants and geothermal resource development to the extent incurred.
Capitalized interest and other deferred charges are amortized over the lives of
the related assets.
 
  Deferred financing costs are amortized over the term of the related
financing. Loan fees are amortized using the implicit interest method; other
deferred financing costs are amortized using the straight-line method.
Accumulated amortization at December 31, 1993 and 1992 was approximately $1,954
and $950, respectively.
 
 Revenue Recognition
 
  Revenues are recorded based upon service rendered and electricity and steam
delivered to the end of the month.
 
 Management Fee and Interest Revenue Recognition
   
  The Company charges the Coso Joint Ventures management fees, operator fees
and interest on outstanding advances. Recognition of fees and interest relating
to power plants and resource development of the Coso Joint Ventures in which
the Company has invested is deferred until each Coso Joint Venture commences
operations. Revenue previously deferred is amortized over the lives of the
related assets of the Coso Joint Ventures as each Coso Joint Venture becomes
operational.     
 
 Deferred Income Taxes
 
  On January 1, 1993, the Company adopted Statement of Financial Accounting
Standard No. 109 (FAS 109), "Accounting for Income Taxes". The adoption of FAS
109 changes the Company's method of accounting for income taxes from the
deferred method as required by Accounting Principles Board Opinion No. 11 to an
asset and liability approach.
 
 Net Income Per Common Share
 
  Earnings per common share are based on the weighted average number of common
and dilutive common equivalent shares outstanding during the period computed
using the treasury stock method.
 
 Cash Flows
 
  The statement of cash flows classifies changes in cash according to
operating, investing or financing activities. Investing activities include
capital expenditures incurred in connection with the power plants, wells,
resource development and exploration costs. The Company considers all
investment instruments purchased

with a maturity of three months or less to be cash equivalents. Restricted cash
is not considered a cash equivalent.
 
 Reclassification
 
  Certain amounts in the fiscal 1992 and 1991 financial statements and
supporting footnote disclosures have been reclassified to conform to the fiscal
1993 presentation. Such reclassification did not impact previously reported net
income or retained earnings.
 
3. INTEREST RATE SWAP AGREEMENTS
   
  In January 1993, the Coso Joint Ventures entered into five year deposit
interest rate swap agreements which effectively convert a notional deposit, the
Company's portion of the balance is $20,300 (restricted cash and investments),
from a variable rate to a fixed rate. The Company's proportion of the deposit
amount accretes annually to a maximum amount of approximately $29,300 in 1996.
Under the agreements, which mature on January 11, 1998, the Coso Joint Ventures
make semi-annual payments to the counter party at variable rates based on
LIBOR, reset and compounded every three months, and in return receive payments
based on a fixed rate of 6.34%. The effective LIBOR rate ranged from 3.25% to
3.375% during 1993 and was 3.375% at December 31, 1993. The counter party to
this agreement is a large multi-national financial institution. The Company's
proportionate share of the carrying amount, representing accrued interest
receivable, and the fair value of the swap agreements are $277 and $1,281,
respectively. The fair value is based on quoted market prices provided by the
counter party to the swap.     
 
  In September 1993, the Company entered into a three year deposit interest
rate swap agreement, which effectively converts a notional deposit balance of
$75,000 from a variable rate to a fixed rate. The Company makes semi-annual
payments to the counter party at effectively the LIBOR rate, reset every six
months, and in return receives payments based on a fixed rate of 4.87%. The
counter party to this agreement is the same counter party to the Coso Joint
Ventures. The carrying amount is $286, representing accrued interest
receivable. The fair value of the interest rate swap is currently negative in
the amount of $642 which is based on quoted market prices provided by the
counter party to the swap.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
                  FOR THE THREE YEARS ENDED DECEMBER 31, 1993
          (DOLLARS AND SHARES IN THOUSANDS, EXCEPT PER SHARE AMOUNTS)
 
 Operating Facilities
   
  The Coso operating facilities comprise the Company's proportionate share of
the assets of three of its Joint Ventures; Coso Finance Partners (Navy I Joint
Venture), Coso Energy Developers (BLM Joint Venture), and Coso Power Developers
(Navy II Joint Venture). With respect to the Coso Project, distributions from
its project accounts are made semi-annually to each Coso Joint Venture partner
for profit sharing under a prescribed calculation subject to mutual agreement
by the partners and compliance with the Coso Joint Ventures' financing
documents. As of December 31, 1993, payout had only been reached on Units 2 and
3 of the Navy I power plant.     
   
 Navy I Plant     
   
  The Navy I Plant consists of three turbines, of which one unit commenced
delivery of firm power in August 1987, and the second and third units in
December 1988. The 80 NMW power plant is located on land owned by and leased
from the U.S. Navy through December 2009, with a 10 year extension at the
option of the Navy. Under terms of the Navy I Joint Venture, profits and losses
were allocated approximately 49% before payout of units 2 and 3 and
approximately 46.4% thereafter to the Company.     
 
 BLM Plant
   
  The BLM Plant consists of two turbines at one site (BLM East), which
commenced delivery of firm power in March and May 1989, respectively, and one
turbine at another site (BLM West) which commenced delivery of firm power in
August 1989. The BLM Plant is situated on lands leased from the U.S. Bureau of
Land Management under a geothermal lease agreement that extends until October
31, 2035. The lease may be extended to 2075 at the option of the BLM. Under the
terms of the BLM Joint Venture agreement, the Company's share of profits and
losses before and after payout is approximately 45% and 48%, respectively.
During 1990, the Company upgraded the cooling tower and turbines to increase
the plant's capacity to 80 NMW from the initial level of 70 NMW.     
 
 Navy II Plant
   
  The Navy II Plant consists of three turbines, of which two units commenced
delivery of firm power in January 1990, and the third in February 1990,
respectively. The 80 NMW power plant is on the southern portion of the Navy
lands. Under terms of the Joint Venture, all profits, losses and capital
contributions for Navy II are divided equally by the two partners.     
 
 Significant Customer
   
  All of the Company's sales of electricity from the Coso Project, which
comprise approximately 94% of 1993 electricity and steam revenues, are to
Southern California Edison (SCE) and are under long-term power purchase
contracts. Under the terms of these contracts, SCE pays firm prices for the
energy portion of the contract. The energy payment escalates pursuant to the
contracts at an average rate of approximately 7.0% per year for the delivery of
electricity for ten years, commencing with the initial delivery of electricity
at firm power; thereafter, the energy payment adjusts to the actual avoided
energy cost experienced by SCE at that time. The capacity payment, which
initially represented approximately 25% of the Company's revenue, remains fixed
during the entire period of the contract. In addition, the Company is eligible
for bonus payments based on the amount by which the actual output exceeds the
contract capacity of each power plant. Bonus payments aggregated $3,050, $3,257
and $2,635 in the years ended December 31, 1993, 1992 and 1991.

  The Company has three contracts for terms of 24, 30 and 20 years, expiring in
2011, 2019 and 2010, respectively. Delivery of electricity by the Navy I Joint
Venture, the BLM Joint Venture and the Navy II Joint Venture commenced under

</TABLE>
 
  The amount of royalties paid by the Company to the U.S. Navy to develop
geothermal energy for Navy I, Unit 1 on the lands owned by the Navy comprises
(i) a fee payable during the term of the contract based on the difference
between the amounts paid by the Navy to SCE for specified quantities of
electricity and the price as determined under the contract (which currently
approximates 65% of that paid by the Navy to SCE), and (ii) $11,600 payable in
December 2009. The $11,600 payment is secured by funds placed on deposit
monthly, which funds, plus accrued interest, will aggregate $11,600. The
monthly deposit is currently $23. As of December 31, 1993, the balance of funds
deposited approximated $1,283, which amount is included in restricted cash and
accrued liabilities.
   
  Units 2 and 3 of Navy I and the Navy II power plants are on Navy lands, on
which the Navy receives a royalty based on electric sales revenue at the
initial rate of 4% escalating to 22% by the end of the contract in December
2019. The BLM is paid a royalty of 10% of the value of steam produced by the
geothermal resource supplying the BLM Plant.     
 
 Pacific Northwest Geothermal Exploration Costs
 
  In the Pacific Northwest, the Company has acquired leasehold rights and has
performed certain geological evaluations to determine the resource potential of
the underlying properties. Recovery of those costs is ultimately dependent upon
the Company's ability to prove geothermal reserves and sell geothermal steam,
or to obtain financing, build power plants, gain access to high voltage
transmission lines, and sell the resultant electricity at favorable prices or,
sell its leaseholds. In the opinion of management, the Company will be able to
realize its exploration costs through the generation of electricity for sale.
 
 Nevada and Utah Properties
 
  On May 3, 1990, the Company entered into a definitive purchase agreement with
a subsidiary of Chevron Corporation (Chevron) for the acquisition of certain
geothermal operations, including interests in approximately 83,750 acres of
geothermal properties in Nevada and Utah, for an aggregate purchase price of
approximately $51,100. These property interests consist largely of leasehold
interests, including properties leased from the BLM and from private
landowners.

                  FOR THE THREE YEARS ENDED DECEMBER 31, 1993
          (DOLLARS AND SHARES IN THOUSANDS, EXCEPT PER SHARE AMOUNTS)
   
  The property acquired from Chevron includes a 9 MW power plant at Desert
Peak, Nevada ("Desert Peak"), and a 70% interest in a steam field at Roosevelt
Hot Springs, Utah ("Roosevelt Hot Springs"). The facility at Desert Peak is
currently selling electricity to Sierra Pacific Power Company under a contract
that runs through 1995 and then may be extended on a year-to-year basis as
agreed by the parties. The price for electricity under this contract is 6.5
cents per kWh, comprising an energy payment of 2.0 cents per kWh (which is
adjustable pursuant to an inflation based index) and a capacity payment of 4.5
cents per kWh. The Roosevelt Hot Springs site has a contract to sell steam to a
25 MW power plant owned by Utah Power and Light Company (UP&L) and to dispose
of the brine that is a by-product of the electricity production process.     
   
  As part of the Nevada and Utah properties acquisition the Company acquired
leasehold interests in an aggregate of approximately 20,000 acres at the
Roosevelt site in Utah and approximately 63,750 acres at four sites in Nevada.
The Roosevelt Hot Springs and Desert Peak properties have been the subject of
exploration and testing by Chevron and its predecessors. Based on these tests
and reports of independent engineering companies, the Company believes that
there are significant geothermal resources available for commercial development
at these sites. Other tests conducted by Chevron and its predecessors indicate
that commercially viable amounts of geothermal resources may underlie the other
Chevron properties.     
   
  The Company financed the acquisition of Roosevelt Hot Springs through an
equity offering, a $20,317 pre-sale of steam from the Roosevelt Hot Springs
field to the utility-owned power plant located at the site, and seller
financing. The acquisition of Roosevelt Hot Springs and certain of the Nevada
properties closed on January 22, 1991 for an aggregate amount of approximately
$35,000. The remainder of the transaction closed on March 28, 1991 and was
financed with seller financing and the proceeds of the sale of common stock to
Kiewit Energy Company (Kiewit Energy); see Note 12.     
 
5. PROJECT LOANS
 
  Project loans, which are non-recourse to the Company, comprise the following

   PROJECT LOANS with fixed interest rates (weighted
    average interest rates of 8.04% and 7.88% at December
    31, 1993 and 1992, respectively) with scheduled
    repayments through December 2001.....................  $246,880 $ 263,604
</TABLE>
   
  The project loans are from Coso Funding Corp. ("Funding Corp."). Funding
Corp. is a single-purpose corporation formed to issue notes for its own account
and as an agent acting on behalf of Navy I, BLM, and Navy II Joint Ventures,
collectively the "Coso Joint Ventures." Pursuant to separate credit agreements
executed between Funding Corp. and each Coso Joint Venture on December 16,
1992, the proceeds from Funding Corp.'s note offering were loaned to the Coso
Joint Ventures. The proceeds of $560,245 were used by the Coso Joint Ventures
to (i) purchase and retire project finance debt comprised of the term loans and
construction loans in the amount of $424,500, (ii) fund contingency funds in
the amount of $68,400, (iii) fund debt service reserve funds in the amount of
$40,000, and (iv) finance $27,345 of capital expenditures and transaction
costs. The contingency fund and debt service reserve fund were required by the
project loan agreements.     
   
  The contingency fund represented the approximate maximum amount, if any,
which could theoretically have been payable by the Coso Joint Ventures to third
parties to discharge all liens of record and other contract claims encumbering
the Coso Joint Ventures' plant at the time of the project loans (See Note 13).
The contingency fund was established in order to obtain investment-grade
ratings to facilitate the offer and sale of the notes by Funding Corp., and
such establishment did not reflect the Coso Joint Ventures' view as to the
merits or likely disposition of such litigation or other contingencies. On June
9, 1993, MPE and the

Mission Power Group, subsidiaries of SCECorp., and the Coso Joint Ventures
reached a final settlement of all of their outstanding disputes and claims
relating to the construction of the Coso Project. As a result of the various
payments and releases involved in such settlement, the Coso Joint Ventures
agreed to make a net payment of $20,000 to MPE from the cash reserves of the
Coso Project contingency fund and MPE agreed to release its mechanics' liens on
the Coso Project. After making the $20,000 payment, the remaining balance of
the Coso Project contingency fund (approximately $49,300) was used to increase
the Coso Project debt reserve fund from approximately $43,000 to its maximum
fully-funded requirement of $67,900. The remaining $24,400 balance of
contingency fund was retained within the Coso Project for future capital
expenditures and for Coso Project debt service payments. Since the Coso Project
debt service reserve is fully funded in advance, Coso Project cash flows
otherwise intended to fund the Coso Project debt service reserve fund, subject
to satisfaction of certain covenants and conditions contained in the Coso Joint
Ventures' refinancing documents, may be available for distribution to the
Company in its proportionate share.
   
  The loans are collateralized by, among other things, the power plants,
geothermal resource, debt service reserve funds, contingency funds, pledge of
contracts, and an assignment of all such Coso Joint Ventures' revenues which
will be applied against the payment of obligations of each Coso Joint Venture,
including the project loans. Each Coso Joint Venture's assets will secure only
its own project loan, and will not be cross-collateralized with assets pledged
under other Coso Joint Venture's credit agreements. The project loans are non-
recourse to any partner in the Coso Joint Ventures and Funding Corp. shall
solely look to such Coso Joint Venture's pledged assets for satisfaction of
such project loans. However, the loans are cross-collateralized by the
available cash flow of each Coso Joint Venture. Each Coso Joint Venture after
satisfying a series of its own obligations has agreed to advance support loans
(to the extent of available cash flow and, under certain conditions, its debt
service reserve funds) in the event revenues from the supporting Coso Joint
Ventures are insufficient to meet scheduled principal and interest on their
separate project loans.     
 
  The annual repayments of the project loans for the five years beginning
January 1, 1994 and thereafter are as follows:

  Based on quoted market rates of the Funding Corp. notes, the fair value of
the project loan was approximately $260,276 at December 31, 1993.
   
  In connection with the aforementioned refinancing, the Company entered into
an agreement with Community Energy Alternatives Incorporated ("CEA") for the
Company to purchase at the close of the Coso Project refinancing CEA's interest
in the Coso Project. Until the close of the Coso Project refinancing, CEA had
been a partner in a partnership structure organized by the Company's Joint
Venture Partner in the BLM Project. The Company purchased the CEA interest
under certain terms and conditions which are designed to provide the Company
with a 17% per annum return on the CEA interest purchase price of $9,800. The
Company's 17% per annum return is secured in part by a pledge and assignment to
the Company of certain cash flows to be received by the Company's Coso Project
Joint Venture Partner (and certain affiliates) from

Coso Project distributions. The Company has granted its Coso Project Joint
Venture Partner the right to purchase the CEA interest for a price which will
provide the Company a 17% per annum return for the duration the Company owns
the CEA interest.
 
6. SENIOR NOTES
 
  The Senior Notes are due in March 1995, and bear interest at the rate of 12%
per annum, plus 10% of the Company's share of the cash flow from the Coso
Project, commencing July 1, 1989 and terminating December 31, 1994. The Senior
Notes prohibit the payment of cash dividends unless the Company has a net worth
of at least $50,000 after payment of such dividends, and dividends do not
exceed 50% of accumulated net income subsequent to December 31, 1987. The
Senior Notes also place restrictions on capital expenditures not related to the
Coso Project. The fair value of the Senior Notes approximates the carrying
value.
 
7. CONVERTIBLE SUBORDINATED DEBENTURES
   
  In June of 1993, the Company issued $100,000 principal amount of 5%
convertible subordinated debentures (debentures) due July 31, 2000. The
debentures are convertible into shares of the Company's common stock at any
time prior to redemption or maturity at a conversion price of $22.50 per share,
subject to adjustment in certain circumstances. Interest on the debentures is
payable semi-annually in arrears on July 31 and January 31 of each year,
commencing on July 31, 1993. The debentures are redeemable for cash at any time
on or after July 31, 1996 at the option of the Company. The redemption prices
commencing in the twelve month period beginning July 31, 1996 (expressed in
percentages of the principal amount) are 102%, 101%, 100% and 100% in 1996,
1997, 1998 and 1999, respectively. The debentures are unsecured general
obligations of the Company and subordinated to all existing and future senior
indebtedness of the Company. The fair value of the debentures as of December
31, 1993 was approximately $103,250, which is based on quoted market rates.
    
8. INCOME TAXES
   
  On January 1, 1993, the Company adopted Statement of Financial Accounting
Standard No. 109 (FAS 109), "Accounting for Income Taxes." The adoption of FAS
109 changes the Company's method of accounting for income taxes from the
deferred method as required by Accounting Principles Board Opinion No. 11 to an
asset and liability approach. Under FAS 109, the net excess deferred tax
liability as of January 1, 1993 was determined to be $4,100. This amount is
reflected in 1993 income as the cumulative effect of a change in accounting
principle. It primarily represents the recognition of the Company's tax credit
carryforwards as a deferred tax asset. There was no cash impact to the Company
upon the required adoption of FAS 109. Under FAS 109, the effective tax rate
increased to approximately 30% from 23.5% in 1992. This increase was due to the
Company's tax credit carryforward being recognized as an asset and unavailable
to reduce the current period's effective tax rate for computing the Company's
provision for income taxes.

  In 1992, the significant components of the deferred tax liability were timing
differences in the computation of depreciation and amortization of the power
plants and exploration and development costs for financial reporting purposes
versus income tax purposes.
 
  As of December 31, 1993, the Company has an unused net operating loss (NOL)
carryover of approximately $113,000 for regular federal tax return purposes
which expires primarily between 2001 and 2007. In addition, the Company has
unused investment and geothermal energy tax credit carryforwards of
approximately $40,106 expiring between 2002 and 2008. The Company also has
approximately $12,018 of alternative minimum tax credit carryforwards which
have no expiration date.
 
9. COMMITMENTS
 
  The Company's former office space lease, which requires annual rental of $660
through April 1994, has been partially sublet at annual rentals of $261 and
remaining future rental costs were previously provided for in a restructuring
charge. The Company also leases an aircraft under a lease that expires on
August 1, 1995, at an annual rental of approximately $464. The aircraft has
been subleased at an annual rental of approximately $300. Rental expense for
the aircraft, vehicles, geothermal leases, and other equipment leases for the
years ended December 31, 1993, 1992 and 1991 was approximately $1,143, $1,018
and $986 respectively.

10. PREFERRED STOCK
 
 SERIES A:
   
  On December 1, 1988, the Company distributed a dividend of one preferred
share purchase right (right) for each outstanding share of common stock. The
rights are not exercisable until ten days after a person or group acquires or
has the right to acquire, beneficial ownership of 20% or more of the Company's
common stock or announces a tender or exchange offer for 30% or more of the
Company's common stock. Each right entitles the holder to purchase one one-
hundredth of a share of Series A junior preferred stock for $52. The rights may
be redeemed by the Board of Directors up to ten days after an event triggering
the distribution of certificates for the rights. The rights plan was amended in
February 1991 so that the agreement with Kiewit Energy (See Note 12) would not
trigger the exercise of the rights. The rights will expire, unless previously
redeemed or exercised, on November 30, 1998. The rights are automatically
attached to, and trade with, each share of common stock.     
 
 SERIES B:
 
  On November 15, 1990, the Company sold 357.5 shares of convertible preferred
stock, Series B at $14 per share. Each share of the convertible preferred stock
was convertible into two shares of common stock, and had a dividend rate of 15%
through November 15, 1992, 10% from November 16, 1992 to November 15, 1994 and
5% from November 16, 1994 to November 15, 1996. The dividends were payable
semi-annually in convertible preferred stock, Series B.

  On November 15, 1992, the Company called the preferred stock for conversion
into common stock. Each Series B preferred stock was converted into two shares
of common stock; accordingly, the Company issued 954.9 shares of common stock.
 
 SERIES C:
   
  On November 19, 1991, the Company sold one thousand shares of convertible
preferred stock, Series C at $50,000 per share to Kiewit Energy, in a private
placement. Each share of the Series C preferred stock is convertible at any
time at $18.375 per common share into 2,721 shares of common stock subject to
customary adjustments. The Series C preferred stock has a dividend rate of
8.125%, commencing March 15, 1992 through conversion date or December 15, 2003.
The dividends, which are cumulative, are payable quarterly in convertible
preferred stock, Series C, through March 15, 1995 and in cash on subsequent
dividend dates.     
 
  The Company is obligated to redeem 20% of the outstanding preferred stock,
Series C each December 15, commencing 1999 through 2003 at a price per share
equal to $50,000, plus accrued and unpaid dividends.
 
  At any time after December 15, 1994, upon 20 days written notice, the Company
may redeem all, or any portion consisting of at least $5,000, of the preferred
stock, Series C, then outstanding, provided that the Company's common stock has
traded at or above 150% of the then effective conversion price, for any 20
trading days out of 30 consecutive trading days ending not more than five
trading days prior to notice of redemption.
   
  The Company may also exchange the preferred stock, Series C, in whole or part
on any dividend date commencing December 15, 1994, for 9.5% Convertible
Subordinated Debentures of the Company due 2003.     
   
  Each share of preferred stock, Series C shall be entitled to the number of
votes equal to $50,000 per share divided by the then effective conversion
price. If cash dividends are in arrears six consecutive quarters, Kiewit Energy
shall have the exclusive right, voting separately as a class, to elect two
directors of the Company.     
 
  No cash dividends shall be paid or declared on the Company's common stock
unless all accumulated dividends on the Series C preferred stock have been
paid.
 
11. STOCK OPTIONS AND WARRANTS
 
  The Company has issued various stock options and warrants. As of December 31,
1993, a total of 8,953 shares are reserved for stock options, of which 8,514
shares have been granted and remain outstanding at prices of $3.00 to $19.00
per share.
 
 Stock Options
 
  The Company has stock option plans under which shares were reserved for grant
as incentive or non-qualified stock options, as determined by the Board of
Directors. As of December 31, 1993, the total options granted for the non-1986
plan and the 1986 plan are 5,778 and 6,354, respectively. The plans allow
options to be granted at 85% of their fair market value at the date of grant.
Generally, options are issued at 100% of fair market value at the date of
grant. Options granted under the 1986 Plan become exercisable over a period of
three to five years and expire if not exercised within ten years from the date
of grant or, in some instances a lesser term. Prior to the 1986 Plan, the
Company granted 256 options at fair market value at date of grant which had
terms of ten years and were exercisable at date of grant. In addition, the
Company had issued

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)

          (DOLLARS AND SHARES IN THOUSANDS, EXCEPT PER SHARE AMOUNTS)
   
  On October 13, 1992, the Company repurchased, and cancelled, certain warrants
exercisable for 1,025 shares of unregistered common stock at $2.04 per share,
for a purchase price of $9.16 per share or $9,389 in aggregate. Separately,
Kiewit Energy simultaneously purchased and exercised other warrants to purchase
600 shares of unregistered common stock at $2.04 per share, providing the
Company with proceeds of $1,224.     
 
  On October 27, 1992, the Company repurchased, and cancelled, certain warrants
exercisable for 250 shares of unregistered common stock at $2.04 per share, for
a purchase price of $9.316 per share or $2,329 in aggregate.
 
12. COMMON STOCK SALES & RELATED OPTIONS
 
  In January 1991, the Company sold 2,505 shares of unregistered common stock
at $6.75 per share for an aggregate total of $16,909. The funds were used to
repay a portion of the seller financing related to the Company's acquisition of
Chevron's interest in Roosevelt Hot Springs, Utah.
   
  The Company and Kiewit Energy signed a stock purchase agreement and related
agreements, dated as of February 18, 1991. Kiewit Energy is a subsidiary of
Peter Kiewit Sons', Inc. of Omaha, Nebraska, a large construction and mining
company with diversified operations. Under the terms of the agreements, Kiewit
Energy purchased 4,000 shares of common stock at $7.25 per share and received
options to buy 3,000 shares at a price of $9 per share exercisable over three
years and an additional 3,000 shares at a price of $12 per share exercisable
over five years (subject to customary adjustments).     
   
  In connection with this initial stock purchase, the Company and Kiewit Energy
also entered into certain other agreements pursuant to which (i) Kiewit Energy
and its affiliates agreed not to acquire more than 34% of the outstanding
common stock (the Standstill Percentage) for a five-year period, (ii) Kiewit
Energy became entitled to nominate at least three of the Company's directors,
and (iii) the Company and Kiewit Energy agreed to use their best efforts to
negotiate and execute a joint venture agreement relating to the development of
certain geothermal properties in Nevada and Utah.     
   
  On June 19, 1991, the board approved a number of amendments to the stock
purchase agreement and the related agreements. Pursuant to those amendments,
the Company reacquired from Kiewit Energy the rights to develop the Nevada and
Utah properties, and Kiewit Energy agreed to exercise options to acquire 1,500
shares of Common Stock at $9.00 per share, providing the Company with $13,500
in cash. The Company also extended the term of the $9.00 and $12.00 options to
seven years; modified certain of the other terms of these options; granted to
Kiewit Energy an option to acquire an additional 1,000 shares of the
outstanding Common Stock at $11.625 per share (closing price for the shares on
the American Stock Exchange on June 18, 1991 for a ten year term); and
increased the Standstill Percentage from 34% to 49%.     
   
  On November 19, 1991, the Board approved the issuance by the Company to
Kiewit Energy of one thousand shares of Series C Preferred Stock for $50,000
per share, as described in Note 10 above. In connection with the sale of the
Series C Preferred Stock to Kiewit Energy, the Standstill Agreement was amended
so that the 49% Standstill Percentage restriction would apply to voting stock
rather than just common stock.     
 
13. LITIGATION
 
 Settlement of Contractor Claims
   
  In June 1990, Mission Power Engineering Company (MPE), a subsidiary of
SCECorp. and the general contractor for eight of the nine facilities at the
Coso Project recorded mechanic's liens (the Liens) against two of the Coso
Projects and filed suit to pursue claims for amounts allegedly due from the
Coso Joint

Ventures in connection with the turnkey contracts for the design and
construction on eight of the units. In July 1990, MPE, the Joint Venture
Partners and the Company agreed to enter settlement discussions during which
period the suit was suspended. In January 1991, MPE terminated settlement
discussions and refiled its suit in the amount of approximately $70,900 in
contract claims. The Coso Joint Ventures counterclaimed on January 10, 1991,
for performance and equipment related and other damages arising under the
turnkey contracts.     
 
  On June 9, 1993, MPE and the Mission Power Group, subsidiaries of SCECorp,
and the Coso Joint Ventures and the Company announced that the companies had
reached a final settlement of all of their outstanding disputes relating to the
construction of and the filing of mechanics' liens against the Coso Project.
 
  Under the settlement agreement, MPE agreed to dismiss with prejudice its
$70,900 breach of contract suit against the Coso Joint Ventures and the Coso
Joint Ventures agreed to dismiss with prejudice their counterclaims against MPE
and related parties. As a result of the various payments and releases involved
in such settlement, the Coso Joint Ventures agreed to make a net payment of
$20,000 to MPE from the cash reserves of the Coso Project Contingency Fund and
MPE agreed to release its mechanics' liens on the Coso Project.
 
 Settlement of Transmission Line Disputes
   
  In September 1990, the California Public Utilities Commission (CPUC) issued a
decision which would fix at approximately $10,500 the Coso Joint Ventures'
maximum exposure for the cost of the construction of a new 220kV electric
transmission line (Line) on the SCE transmission system. The Coso Joint
Ventures appealed the decision of the CPUC to the Federal district court and
intended to petition the CPUC to reconsider its decision on the grounds that
such line is not necessary. In a related proceeding involving the cost
allocation for existing and ancillary interconnection facilities, the CPUC
ruled that the Coso Joint Ventures' share would be approximately $7,000. The
Coso Joint Ventures appeal of such decision to the California Supreme Court was
denied in February 1993. In addition, SCE alleged certain line losses that SCE
deemed applicable to the existing 115kV line utilized by two of the Coso Joint
Ventures and deducted amounts from revenues payable under the power purchase
contracts. The Coso Joint Ventures dispute SCE's allegations, methodology and
alleged ability to deduct amounts under the interconnection contracts and filed
a complaint alleging breach of contract in the California State Court.     
   
  On May 3, 1993, SCE and the Coso Joint Ventures agreed to settle the
transmission line loss contract dispute and certain related interconnection
disputes involving the Coso Project under a separate agreement whereby, among
other things, the parties made certain cash payments to each other and agreed
to certain interconnection cost and historical line loss allocations and to the
release to the Coso Joint Ventures of certain funds previously deducted from
project revenues and held in escrow. The parties also agreed to jointly pursue
appropriate rate treatment by the CPUC of certain SCE financed interconnection
costs, including the one remaining cost allocation issue between them in the
amount of $5,900. As a result of the various payments, allocations and releases
involved in such partial settlement, SCE released $15,500 of Coso Project funds
(the Company's share was approximately $7,800) held in escrow in respect of
interconnection costs (transmission line deposit) and the Partners of Coso
Joint Ventures' posted an irrevocable letter of credit to support their
contingent obligation of $5,900 on the cost allocation matter to be jointly
pursued with SCE at the CPUC.     
 
 Settlement of Anti-Trust Lawsuit
   
  On January 31, 1991, the Company filed an antitrust lawsuit in San Francisco
Federal Court against SCECorp., its subsidiaries (MPE, Mission Power Group and
SCE) and Kidder-Peabody & Co., and others alleging violations of the federal
antitrust laws, unfair competition and tortious interference. This lawsuit was
settled in conjunction with the transmission line disputes.

          (DOLLARS AND SHARES IN THOUSANDS, EXCEPT PER SHARE AMOUNTS)
 
 Settlement with Joint Venture Partner
   
  The Company has served as managing partner, project manager and field
operator for the Coso Project since its inception. It has been plant operator
for the facilities since August 1988. In April 1990, the Company's principal
Coso Joint Venture partner (the J.V. Partner) served the Company and certain of
the Company's subsidiaries with a demand for arbitration arising out of
disagreements concerning primarily the operating budgets and the allocation to
the Joint Ventures of certain expenses incurred by the Company.     
 
  On March 19, 1991, the Company and its J.V. Partner executed a settlement
agreement which resolved all their outstanding disputes. The terms of the
settlement provide that if the Coso Project performs at capacity level in the
future so that certain formula-based contingencies related to the productivity
of the power plants are satisfied in any of the following eight years, then,
out of the excess cash flow generated from such performance levels, up to $1.4
million may be paid in each such year to the J.V. Partner by the Company.
During 1992, the Company purchased the J.V. Partner's contingent payment for
$5,000; which will be amortized over the remaining seven years of the
agreement.
   
  In return for the original settlement, the J.V. Partner agreed to the
conversion of all prior advances made by the Company on behalf of the
partnership into a Coso Joint Venture note payable to the Company due on or
before March 19, 1999. The note bore interest at an adjustable rate tied to
LIBOR and was subordinated to the prior payment in full of all the senior bank
debt on the project as well as to the foregoing contingent payments to the J.V.
Partner. On December 16, 1992 the Coso Joint Ventures paid $5,133 of their note
payable plus accrued interest to the Company. A new promissory note was then
signed on December 16, 1992 for the remaining principal balance. This note
bears a fixed interest rate of 12.5% and is payable on or before March 19,
2002. This note continues to be subordinated to the senior project loan on the
project. The fair value of this note approximates the carrying value.     
 
14. RELATED PARTY TRANSACTIONS
   
  The Company charged and recognized a management fee and interest on advances
to its Coso Joint Ventures, which aggregated approximately $5,354, $4,246 and
$5,664 in the years ended December 31, 1993, 1992 and 1991.     
 
15. EXTRAORDINARY ITEM
 
  The refinancing of the Coso Joint Ventures' project financing debt in 1992
resulted in an extraordinary item in the amount of $4,991, after the tax effect
of $1,533. The extraordinary item represents the unamortized portion of the
deferred financing costs and related repayment costs associated with the
original Coso Joint Ventures' project financing debt.
 
16. SUBSEQUENT EVENT
 
  The Company is currently in the process of arranging a proposed offering of
$400,000 Senior Discount Notes (Notes). The interest rate will be between
approximately 9% and 10%, with cash interest payment commencing in 1997. The
Notes will be senior unsecured obligations of the Company. The Company intends
to use the proceeds from the offering to: (i) fund equity commitments in, and
the construction costs of, geothermal power projects presently planned in the
Philippines and Indonesia, (ii) to fund equity investments in, and loans to,
other potential international and domestic private power projects and related
facilities, (iii) for corporate or project acquisitions permitted under the
Indenture, and (iv) for general corporate purposes.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
  Section 145 of the General Corporation Law of the State of Delaware (the
"DGCL") grants each corporation organized thereunder, such as the Company, the
power to indemnify its directors and officers against liabilities for certain
of their acts. Article EIGHTH of the Company's Restated Certificate of
Incorporation and Article V of the Company's By-Laws provides for
indemnification of directors and officers of the Company to the extent
permitted by the DGCL. Article V of the Company's By-Laws further provides that
the Registrant may enter into contracts providing indemnification to the full
extent authorized or permitted by the DGCL and that the Company may create a
trust fund, grant a security interest and/or use other means to ensure the
payment of such amounts as may become necessary to effect indemnification
pursuant to such contracts or otherwise.
 
  Section 102(b)(7) of the DGCL permits a provision in the certificate of
incorporation of each corporation organized thereunder, such as the Company,
eliminating or limiting, with certain exceptions, the personal liability of a
director to the corporation or its stockholders for monetary damages for
certain breaches of fiduciary duty as a director. Article EIGHTH of the
Company's Restated Certificate of Incorporation eliminates the personal
liability of directors to the full extent permitted by the DGCL.
 
  The foregoing statements are subject to the detailed provisions of Sections
145 and 102(b)(7) of the DGCL, Article EIGHTH of the Company's Restated
Certificate of Incorporation and Article V of the Company's By-laws.

ITEM 17. UNDERTAKINGS
 
  Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
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
registrant of expenses incurred or paid by a director, officer or controlling
person of the registrant 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 registrant 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 registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
registrant's annual report pursuant to section 13(a) or section 15(d) of the
Exchange Act (and, where applicable, each filing of an employee benefit plan's
annual report pursuant to section 15(d) of the Exchange Act) that is
incorporated by reference in the registration statement shall be deemed to be a
new registration statement relating to the securities offered therein, and the
offering of such securities at the time shall be deemed to be the initial bona
fide offering thereof.     
   
  The undersigned registrant hereby undertakes to deliver or cause to be
delivered with the prospectus, to each person to whom the prospectus is sent or
given, the latest annual report to security holders that is incorporated by
reference in the prospectus and furnished pursuant to and meeting the
requirements of Rule 14a-3 or Rule 14c-3 under the Exchange Act; and, where
interim financial information required to be presented by Article 3 of
Regulation S-X is not set forth in the prospectus, to deliver, or cause to be
delivered to each person to whom the prospectus is sent or given, the latest
quarterly report that is specifically incorporated by reference in the
prospectus to provide such interim financial information.     
 
  For purposes of determining any liability under the Securities Act, the
information omitted from the form of prospectus filed as part of this
registration statement in reliance upon Rule 430A and contained in a form of
prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h)
under the Securities Act shall be deemed to be part of this registration
statement as of the time it was declared effective.
   
  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.
