  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

                              the Company ranking pari passu in right 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%

                              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 $209.2
                              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."

                              certain covenants which, among other things, will

(1) The Coso Project consists of three geothermal facilities (referred to
    herein as the "Navy I Plant," the "BLM Plant" and the "Navy II Plant"). The
    Navy I Plant commenced operation prior to 1989 and the BLM and Navy II
    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" and "Use of Proceeds."     
 
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" and "Use of Proceeds."     
 
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 $209.2 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, 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
Notes have been approved for listing on the New York Stock Exchange, subject to
official notice of issuance. There can be no assurance, however, 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.

                                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

  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
<PAGE>

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 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 April 8, 1994 (subject to extension by agreement
of the parties) 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 is available and, if
appropriate, will request similar coverage from the Export-Import Bank of
Japan for Japanese goods and services. 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 theinterim 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.

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 $3.6
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.
 
 
                                       50

contracts and sublease described above are comparable to available terms in
similar transactions with unaffiliated third parties.
 
CERTAIN RELATIONSHIPS

Kiewit, and owns Kiewit stock. Mr. Crowe, a director of the Company, is the

unaffiliated third parties.
 
CERTAIN TRANSACTIONS AND RELATIONSHIPS WITH OTHERS
 
  The Company retained the law firm of Baker & McKenzie during the first half
of 1993. Everett B. Laybourne, a director of the Company, was of counsel to the
Los Angeles office of Baker & McKenzie. The Company paid to Baker & McKenzie a

to fees that would be payable in similar transactions with unaffiliated third
parties.
 
                            DESCRIPTION OF THE NOTES
 
  The Notes will be issued under an Indenture (hereinafter referred to as the

<PAGE>
 
   
  The Notes will be issued at an original issue discount to their principal
amount to generate gross proceeds to the Company of approximately $    million.
Discount on the Notes will accrete at a rate of    %, compounded semi-annually
on each January 15 and July 15, to an aggregate principal amount of $
million by January 15, 1997. Thereafter, cash interest on the Notes will accrue
at the rate of    % per annum and will be payable semi-annually in arrears on
each January 15 and July 15, commencing July 15, 1997, to the Holders thereof
at the close of business on the preceding January 1 and July 1, respectively.
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.     
 
  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.

  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

<TABLE>
<CAPTION>
             YEAR                     REDEMPTION PRICE
             ----                     ----------------
             <S>                      <C>

             2000....................
             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 $209.2 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
    
                                       52

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."
   
GLOBAL NOTES     
          
  The Notes will be issued in the form of registered global notes (the "Global
Notes") that will be deposited with, or on behalf of, The Depository Trust
Company, New York, New York (the "Depositary") and registered in the name of
the Depositary's nominee. Unless and until exchanged in whole or in part for
Notes in certificated registered form, the Global Notes may not be transferred
except as a whole by the Depositary to another nominee of the Depositary or to
a successor depositary or a nominee of such successor.     
   
  Upon the issuance of the Global Notes, the Depositary will credit on its
book-entry registration and transfer system, the principal amount of the Notes
represented by the Global Notes to accounts of participant institutions that
have accounts with the Depositary. The accounts to be credited shall be
designated by the Underwriters, dealers or agents. Owners of beneficial
interests in the Global Notes that are not participants or Persons that may
hold through participants but desire to purchase, sell or otherwise transfer
ownership of the Notes by book-entry on the records of the Depositary may do so
only through participants and Persons that may hold through participants.
Because the Depositary can only act on behalf of participants and Persons that
may hold through participants, the ability of an owner of a beneficial interest
in the Global Notes to pledge Notes to Persons that do not participate in the
book-entry and transfer system of the Depositary, or otherwise take actions in
respect of such Notes, may be limited. In addition, the laws of some states
require that certain purchasers of securities take physical delivery of such
securities in definitive form. Such limits and such laws may impair the ability
to transfer or pledge beneficial interests in the Global Notes.     
   
  So long as the Depositary, or its nominee, is the registered owner of a
Global Note, the Depositary or its nominee, as the case may be, will be
considered the sole owner or Holder of such Global Note for all purposes under
the Indenture. Except as provided below, owners of beneficial interests in a
Global Note will not be entitled to have Notes registered in their name, will
not receive or be entitled to receive physical delivery of the Notes in
certificated form and will not be considered the owners or Holders thereof
under the Indenture.     
   
  Accordingly, each Person owning a beneficial interest in a Global Note must
rely on the procedures of the Depositary and, if such Person is not a
participant, on the procedures of the participant through which such Person
owns its interest, to exercise any rights of a Holder under the Indenture. The
Company understands that under existing industry practices, in the event that
the Company requests any action of Holders or that an owner of a beneficial
interest in such Global Note desires to take any action that the Depositary, as
the Holder of the Global Notes is entitled to take under the Indenture, the
Depositary would authorize the participants holding the relevant beneficial
interests to take such action, and such participants would authorize beneficial
owners holding through such participants to take such action or would otherwise
act upon the instructions of beneficial owners holding through them.     
   
  Payment of principal of and interest on the Global Notes will be made to the
Depositary or its nominee, as the case may be, as the sole registered owner of
the Global Notes. None of the Company, the Trustee, any paying agent or the
registrar for the Notes will have any responsibility or liability for any
aspect of the records relating to or payments made on account of beneficial
ownership interests in the Global Notes or for maintaining, supervising or
reviewing any records relating to such beneficial ownership interests.     
          
  The Depositary has advised the Company and the Trustee that its current
practice is upon receipt of any payment of principal, premium, if any, or
interest, if any, to immediately credit the accounts of the participants with
such payment in amounts proportionate to their respective holdings in principal
amount of beneficial interest in the Global Notes as shown in the records of
the Depositary. Payments by participants to owners of beneficial interests in
the Global Notes held through such participants will be governed by standing
instructions and customary practices, as is now the case with securities held
for the accounts of customers registered in "street name", and will be the
responsibility of such participants. Owners of beneficial interests in the
Global Notes that hold through the Depositary under a book-entry format (as
opposed to holding certificates directly) may experience some delay in the
receipt of interest payments since the Depositary will forward payments to its
participants, which in turn will forward them to Persons that hold through
participants or such owners.     
 
                                       53

  If the Depositary is at any time unwilling or unable to continue as
depositary and a successor depositary is not appointed by the Company or the
Depositary within ninety days, the Company will issue Notes in definitive form
in exchange for the Global Notes. In addition, the Company or the Depositary
may at any time and in its sole discretion determine not to have the Notes
represented by the Global Notes and, in such event, the Company will issue
Notes in definitive form in exchange for the Global Notes. In either instance,
an owner of a beneficial interest in the Global Notes will be entitled to have
Notes equal in principal amount to such beneficial interest registered in its
name and will be entitled to physical delivery of such Notes in definitive
form. Notes so issued in definitive form will be issued in denominations of
$1,000 and integral multiples thereof and will be issued in registered form
only, without coupons.     
   
  The Depositary has advised the Company and the Underwriters as follows: The
Depositary is a limited-purpose trust company organized under the New York
Banking Law, a "banking organization" within the meaning of the New York
Banking Law, a member of the Federal Reserve System, a "clearing corporation"
within the meaning of the New York Uniform Commercial Code and a "clearing
agency" registered pursuant to the provisions of Section 17A of the Exchange
Act. The Depositary was created to hold securities of participants and to
facilitate the clearance and settlement of securities transactions among the
participants in deposited securities through electronic book-entry changes in
accounts of the participants, thereby eliminating the need for physical
movement of securities certificates. Participants include securities brokers
and dealers (including the Underwriters), banks, trust companies, clearing
corporations and certain other organizations, some of which (and/or their
representatives) own the Depositary. Access to the Depositary's book-entry
system is also available to others such as banks, brokers, dealers and trust
companies that clear through or maintain a custodial relationship with a
participant, either directly or indirectly ("indirect participants"). Persons
who are not participants may beneficially own securities held by the Depositary
only through participants or indirect participants. The rules applicable to the
Depositary and the participants are on file with the Commission. The Depositary
agrees with and represents to its participants that it will administer its
book-entry system in accordance with its rules and bylaws and requirements of
law.     
 
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.
 
 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 to the extent permitted
under the covenant described under "Limitation on Restricted Payments" below as
a "Permitted Investment"), (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 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
    
                                       55
<PAGE>
 
   
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 or an Eligible Joint Venture, 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 being designated as 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, (i) the designation of a Restricted Subsidiary as an Unrestricted
Subsidiary, in the manner provided in the definition of "Unrestricted
Subsidiary," will be an Investment that will be subject to the foregoing
paragraph and (ii) the transfer of the Company's interest (or any portion
thereof) in an entity that has been deemed to be an Eligible Joint Venture,
directly or indirectly, to an Unrestricted Subsidiary will be an Investment (to
the extent of the interest transferred) 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
 
                                       56
<PAGE>
 
   
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 the applicable
jurisdiction, (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 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
 
                                       57
<PAGE>
 
   
Company or any of its Restricted Subsidiaries or any Eligible Joint Venture (or
as otherwise required under the terms of such Debt), provided that, no such
payment of Debt (x) 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 or (y) owed to the Company, a
Restricted Subsidiary thereof or an Eligible Joint Venture will count for this
purpose, 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 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
 
                                       58
<PAGE>
 
   
first sentence of the first paragraph of this covenant, the Company may apply
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 pursuant to this covenant 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, with a copy to the
Trustee, within 30 days after 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"), 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 and
that will contain information concerning the procedures applicable to the Offer
(including, without limitation, the right of withdrawal) and the effect of such
Offer on the Notes tendered. 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 properly tendered by Holders pursuant to the Offer exceeds
the amount of such Excess Proceeds, the Notes or portions of Notes to be
accepted for purchase 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 pursuant to
this covenant 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 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, 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) 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, 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

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

 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 fifth Business Day prior to 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 Purchase 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 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 and purchased, 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 pursuant to this covenant 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.

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,
design, engineer, procure, acquire, operate, service, manage or dispose of
Permitted Facilities, (iii) obtaining, arranging or providing financing
incident to any of the foregoing and (iv) other related activities incident to

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 and 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
under the covenant described under "Limitation on Subsidiary Debt" above,
assuming for the purpose of this covenant and the covenants described under
"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 are at least equal
to the fair market value of the property sold (determined in good faith as
evidenced by an Officers' Certificate delivered to the Trustee in respect of a
transaction involving less than $25 million, or, if equal to or in excess of
$25 million, 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.     
 
 Limitation on Sale of Subsidiary Preferred Stock
 
  The Company will not permit any of its Restricted Subsidiaries or any
Eligible Joint Venture to create, assume or otherwise cause or suffer to exist
any Preferred Stock except: (i) Preferred Stock outstanding on the date of the

Preferred Stock pursuant to the terms of the agreement or instrument that
governs such Preferred Stock as in effect on the date of original issuance of
the Notes, (ii) Preferred Stock held by the Company, a Restricted Subsidiary of
the Company or an Eligible Joint Venture, (iii) Preferred Stock issued by a

another Restricted Subsidiary or another Eligible Joint Venture or (c) a
Restricted Subsidiary or an Eligible Joint Venture merges with or into such
Person (in a transaction in which such Person becomes a Restricted Subsidiary
or an Eligible Joint Venture), provided that such Preferred Stock was not
issued in anticipation of 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,

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

and having a redemption period no shorter than the redemption period of the
Preferred Stock so exchanged or refinanced.     
 
MERGERS, CONSOLIDATIONS AND SALES OF ASSETS
   
  The Company may not consolidate with, merge with or into, or transfer all or
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
or the District of Columbia and will expressly assume in writing all the
obligations of the Company under the Indenture and the Notes, (ii) immediately
after giving effect to such transaction, no Event of Default and no event or
condition that through the giving of notice or lapse of time or both would
become an Event of Default will have occurred and be continuing, (iii)
immediately after giving effect to such transaction on a pro forma basis, the
Company or the surviving entity would be able to Incur at least $1 of Debt
under the provision described in the first paragraph of "Limitation on Debt"
above and (iv) the Net Worth of the Company or the surviving entity, as the
case may be, on a pro forma basis after giving effect to such transaction
(without giving effect to the fees and expenses incurred in respect of such
transaction), is not less than the Net Worth of the Company immediately prior
to such transaction.     
 
  None of the Company, any of its Restricted Subsidiaries or any Eligible Joint
Ventures may merge with or into, or be consolidated with, an Unrestricted
Subsidiary of the Company, except to the extent that such Unrestricted
Subsidiary has been designated a Restricted Subsidiary as provided in the
Indenture in advance of or in connection with such merger.

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

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

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) failure to make an offer required under either of the covenants
described under "Limitation on Dispositions" or "Purchase of Notes Upon a
Change of Control" above or a failure to purchase Notes tendered in respect of
such offer, (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) 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, (vi) 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 (vii) 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, or interest 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 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)(iii)(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
respective Stated Maturities 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 or the Company 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)(iii)(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.     
 
 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," clauses (i) and (iii) with respect to
certain offers for the Notes required by certain covenants and clauses (v) and
(vi) under "Events of Default" will cease to be applicable to the Company, its
Restricted Subsidiaries and its Eligible Joint Ventures 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.     
 
                                       65
<PAGE>
 
 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.

denominated as principal or interest, over the issue price of such Note) that
will theretofore have accrued pursuant to Section 1272 of the Internal Revenue
Code or any successor provision (without regard to Section 1272(a)(7) of the
Internal Revenue Code or any successor provision) from the date of issue of
such Note (a) for each six months or shorter period ending January 15 and July
15 (to January 15, 1997) prior to the date of determination and (b) for the
shorter period, if any, from the end of the immediately preceding six month
period, as the case may be, to the date of determination, minus (iii) all

been Incurred pursuant to clause (iii) of the provision described under
"Limitation on Subsidiary Debt" and all the other Debt of such Person could
have been Incurred by the Company at the time of such merger or acquisition
pursuant to the provision described in the first paragraph of "Limitation on
Debt" above, and provided further that such Debt was not Incurred in connection

Restricted Subsidiary or an Eligible Joint Venture, such Acquired Debt would
fulfill the requirements of the first sentence of this definition if such
Permitted Facilities constituted a single Permitted Facility and (iii) for the
purpose of the Indenture, (a) the Permitted Facilities that jointly secure a

giving holders thereof the right to require the Company to purchase or redeem
such Capital Stock upon the occurrence of an "asset sale" or a "change of
control" occurring prior to the Stated Maturity of the Notes will not
constitute Redeemable Stock if the "asset sale" or "change of control"
provision applicable to such Capital Stock is no more favorable to the holders
of such Capital Stock than the provisions contained in the covenants described
under "Limitation on Dispositions" and "Purchase of Notes Upon a Change of
Control" above and such Capital Stock specifically provides that the Company
will not purchase or redeem any such Capital Stock pursuant to such covenants
prior to the Company's purchase of Notes required to be purchased by the
Company under the covenants described under "Limitation on Dispositions" and
"Purchase of Notes Upon a Change of Control" above.
 
  "Reference Period" is defined to mean the four most recently completed fiscal

the Company's Capital Stock, (iii) any defeasance, redemption, purchase or
other acquisition or retirement for value prior to the scheduled maturity of
any Debt ranked subordinate in right of payment to the Notes other than
repayment of Debt of the Company to a Restricted Subsidiary or an Eligible
Joint Venture, (iv) any Investment made in a Person (other than the Company or
any Restricted Subsidiary or any Eligible Joint Venture) and (v) designating a

made upon such a designation to be determined as the fair market value of the
Capital Stock of such Restricted Subsidiary owned directly or indirectly by the
Company at the time of the designation, but in no event less than the amount of
the Investment made in such Restricted Subsidiary directly or indirectly by the
Company). Notwithstanding the foregoing, "Restricted Payment" will not include
any Permitted Payment, except that any payment made pursuant to clauses (iv)

                   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"
 
                                       82
<PAGE>
 
   
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 will be effective for debt instruments issued on or after April 4,
1994 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
 
                                       83
<PAGE>
 
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 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. 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.     
 
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
 
                                       84
<PAGE>
 
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 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.

</TABLE>
 
  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
 
                                       85
<PAGE>
 
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 Notes have been approved for listing on the New York Stock Exchange,
subject to official notice of issuance. 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. See
"Investment Considerations--No Prior Public Market; Possible Volatility of Note
Price."     
 
  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
 
  The validity of the Notes offered hereby and certain other legal matters in
connection with the Offering are being passed upon for the Company by Steven A.

  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
at December 31:

   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

          (DOLLARS AND SHARES IN THOUSANDS, EXCEPT PER SHARE AMOUNTS)

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:

</TABLE>
 
  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.

          (DOLLARS AND SHARES IN THOUSANDS, EXCEPT PER SHARE AMOUNTS)

  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.

                  FOR THE THREE YEARS ENDED DECEMBER 31, 1993
          (DOLLARS AND SHARES IN THOUSANDS, EXCEPT PER SHARE AMOUNTS)
 
  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

  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

          (DOLLARS AND SHARES IN THOUSANDS, EXCEPT PER SHARE AMOUNTS)
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.

       (xix)  The documents incorporated by reference in the Prospectus and any

   Indenture Act; the Prospectus has been filed with the Commission pursuant
   to the appropriate subparagraph of Rule 424(b) of the Rules and
   Regulations; to the knowledge of such counsel, no stop order suspending the
   effectiveness of the Registration Statement has been issued and no
   proceeding for that purpose is pending or threatened by the Commission;
       
    
        (iii)  The Registration Statement and the Prospectus and any further
   amendments or supplements thereto made by the Company prior to the Delivery
   Date (other than the financial statements, related schedules, other
   financial and statistical information contained therein or omitted
   therefrom as to which such counsel need express no opinion) as of their

        (iv)  The statements in the Prospectus under the captions (A)
   "Description of the Notes" insofar as they purport to summarize the
   provisions of the Indenture and the Notes and (B) "Certain Tax
   Considerations," to the extent that they constitute a summary of federal

   legal conclusions, have been reviewed by such counsel and fairly summarize
   the information or matters described therein;      
    
         (v)  To such counsel's knowledge, there are no contracts or other
   documents which are required to be described in the Prospectus or filed as
   exhibits to the Registration Statement by the Securities Act or by the
   Rules and Regulations which have not been described or filed as exhibits to
   the Registration Statement or incorporated by reference therein as
   permitted by the Rules and Regulations;

       (vii)  The Indenture has been duly authorized, executed and delivered by
   the Company and constitutes a valid and binding obligation of the Company,
   enforceable against the Company in accordance with its terms, except as
   enforcement may be limited by bankruptcy, insolvency, reorganization or
   other similar laws affecting creditors' rights generally and except as
   enforcement thereof is subject to general principles of equity (regardless
   of whether enforcement is considered in a proceeding in equity or at law); 
     
    
      (viii)  The Notes have been duly authorized and executed by the Company,
   and, assuming due authentication by the Trustee, when issued and delivered
   as contemplated by the Indenture upon payment therefor as provided in this
   Agreement, will be validly issued and outstanding and constitute valid and
   binding obligations of the Company entitled to the benefits of the
   Indenture and enforceable against the Company in accordance with their
   terms, except as enforcement may be limited by bankruptcy, insolvency
   (involving, without limitation, all laws relating to fraudulent transfers),
   reorganization or other similar laws affecting creditors' rights generally
   and except as enforcement thereof is subject to general principles of
   equity (regardless of whether enforcement is considered in a proceeding in
   equity or at law);      
    
        (ix)  No consent, authorization, order of, or filing or registration
   by the Company with, any governmental authority or body having jurisdiction
   over the Company is necessary or required for the performance by the
   Company of its obligations under this Agreement, or in connection with the
   issuance and sale of the Notes hereunder, except as may be required under
   applicable state or foreign securities laws or blue sky laws in connection
   with the purchase and distribution of the Notes by the Underwriters;      
    
         (x)  The issuance of the Notes and the compliance by the Company with
   the terms of the Indenture and the Notes will not result in a "Default" or
   "Event of Default" within the meaning of the Senior Notes or the Note
   Purchase Agreement and

   each of (x) the Escrow Deposit Agreement, dated March 3, 1994, among the
   Company, Principal Mutual and Bank of America NT & SA (the "Escrow
   Agreement") and (y) the Defeasance Agreement, dated March 3, 1994, between
   the Company and Principal Mutual (the "Defeasance Agreement"), is a valid
   and binding agreement of the Company and is enforceable against the Company
   in accordance with its terms, except as enforcement may be limited by
   bankruptcy, insolvency (involving, without limitation, all laws relating to
   fraudulent transfers), reorganization or other similar laws affecting
   creditors' rights generally and except as enforcement thereof is subject to
   general principles of equity (regardless of whether enforcement is
   considered in a proceeding in equity or at law); and      
    
        (xi)  The covenants contained in the Senior Notes and the Note Purchase
   Agreement as to which the Defeasance Agreement provides for defeasance (the
   "Defeased Covenants") shall have ceased to be effective and are not binding
   on the Company; the issuance of the Notes and compliance by the Company
   with the terms of the Indenture and the Notes would not constitute a
   "Default" or "Event of Default" within the meaning of the Senior Notes or
   the Note Purchase Agreement in the event the "Defeased Covenants" were
   revived or reinstated in accordance with the terms of the Defeasance
   Agreement; and the opinions set forth in paragraphs (vii) and (viii) as to
   the validity and binding nature, and the enforceability, of the Notes and
   the Indenture would not be affected by any such revival or reinstatement of
   the Defeased Covenants.      
    
     (f)  In the rendering of the opinions described in Section 7(d) and Section
7(e) above, such counsel may (i) state that their opinion is limited to matters
governed by the Federal laws of the United States of America, the laws of the
State of New York, the General Corporation Law of the State of Delaware and,
in the case of the General Counsel of the Company, the laws of the State of
California, and (ii) rely, to the extent they deem proper, in respect of matters
of fact, upon certificates and representations of officers of the Company, the
Subsidiaries or the Joint Ventures and public officials.  Such counsel shall
also have furnished

dated the Delivery Date, in form and substance reasonably satisfactory to the
Representatives to the effect that (i) such counsel (in the case of Willkie
Farr & Gallagher, such counsel may state that they have acted as special
counsel to the Company for purposes of the subject Note Offering) have
participated in conferences with representatives of the Company, some of which
have been attended by the Underwriters and their counsel, at which conferences
the contents of the Registration Statement, the Prospectus, each amendment
thereof and supplement thereto and related matters were discussed, although
such counsel has not independently checked or verified and is not passing upon
and assumes no responsibility for the factual accuracy, completeness or
fairness of the statements contained in the Registration Statement, the
Prospectus, any amendment thereof or supplement thereto, and (ii) based on the
foregoing, no facts have come to the attention of such counsel which cause
them to believe that (except for the financial statements, related schedules
and other financial and statistical information contained therein or omitted
therefrom as to all of which such counsel need not express any belief) (I) the
Registration Statement, as of the Effective Date, contained any untrue
statement of a material fact or omitted to state a material fact required to
be stated therein or necessary in order to make the statements therein not
misleading, or that the Prospectus, as amended and supplemented as of the
Effective Time, contains any untrue statement of a material fact or omits to
state a material fact required to be stated therein or necessary in order to
make the statements therein, in the light of the circumstances under which
they were made, not misleading or (II), in the case of the General Counsel of
the Company, any document incorporated by reference in the Prospectus or any
further amendment or supplement to such incorporated document made by the
Company prior to the Delivery Date when they became effective or were filed
with the Commission, as the case may be, contained, in the case of a
registration statement that became effective under the Securities Act, any
untrue statement of a material fact or omitted to state a material fact
required to be stated therein, in the light of the circumstances under which
they were made, or necessary in order to make the statements therein not
misleading, or, in the case of other documents which were filed under the
Exchange Act with the Commis-      

                                       29

sion, an untrue statement of a material fact or omitted to state a material
fact necessary in order to make the statements therein, in light of the
circumstances under which they were made, not misleading.      
    
     (g)  With respect to the letter of Deloitte & Touche delivered to the
Representatives concurrently with the execution of this Agreement, the Company
shall have furnished to the Representatives a letter (the "bring-down letter")
of such accountants, addressed to the Underwriters and dated the Delivery Date,
(i) confirming that they are independent public accountants within the meaning
of the Securities Act and are in compliance with the applicable requirements
relating to the qualification of accountants under Rule 2-01 of Regulation S-X
of the Commission, (ii) stating, as of the date of the bring-down letter (or,
with respect to matters involving changes or development since the respective
dates as of which specified financial information is given in the Prospectus, as
of a date not more than five days prior to the date of the bring-down letter),
the conclusions and findings of such firm with respect to the financial
information and other matters covered by the initial letter, and (iii)
confirming in all material respects the conclusions and findings set forth in
the initial letter.      
    
     (h)  The Company shall have furnished to the Representatives a certificate,
dated the Delivery Date, of its Chairman of the Board, its President or a Vice
President and its Chief Financial Officer stating that:      
    
         (i)  The representations, warranties and agreements of the Company in
   Section 1 are true and correct as of the Delivery Date; the Company has
   complied with all its agreements contained herein; and the conditions set
   forth in Sections 7(a) and 7(j) have been fulfilled; and      
    
        (ii)  They have carefully examined the Registration Statement and the
   Prospectus and, in their opinion (A) as of the Effective Date, the
   Registration Statement and Prospectus did not include any untrue statement
   of a material fact and did not omit to state a material fact required to be
   stated therein or necessary to make the statements therein, in respect of
   the Prospectus, in the light of the circumstances under which they were
   made, not      

                                       30
<PAGE>
 
    
   misleading, and (B) since the Effective Date no event has occurred which is
   required to be set forth in a supplement or amendment to the Registration
   Statement or the Prospectus which has not been so set forth.      
    
     (i)  Each of the Escrow Agreement and the Defeasance Agreement shall have
become effective in accordance with their terms, and pursuant thereto, the
Defeased Covenants shall have ceased to be effective, and no default or event of
default under the Senior Notes or the Note Purchase Agreement shall have
occurred and be continuing, and the Company shall have furnished or caused to be
furnished to the Representatives (i) satisfactory evidence with respect to the
foregoing and (ii) the consent of Principal Mutual to the issuance of the Notes
and the compliance by the Company with the Indenture and the Notes in form and
substance satisfactory to the Representatives;      
    
     (j)  Since the date of the latest audited financial statements included or
incorporated by reference in the Prospectus (i) there has been no material
adverse change, or a development which is reasonably likely to lead to a
material adverse change, in the financial condition or results of operations of
the Company, its Subsidiaries and Joint Ventures taken as a whole and (ii)
except as disclosed in the Prospectus, there have not been any transactions
entered into by the Company, its Subsidiaries or any Joint Venture, other than
those in the ordinary course of business, which are material and adverse to the
Company, its Subsidiaries and Joint Ventures taken as a whole, and which, in the
judgment of the Representatives, make it impracticable or inadvisable to
proceed with the public offering or the delivery of the Notes on the terms and
in the manner contemplated in the Prospectus.      
    
     (k)  Subsequent to the execution and delivery of this Agreement (i) no
downgrading shall have occurred in the rating accorded the Company's senior debt
securities by any "nationally recognized statistical rating organization", as
that term is defined by the Commission for purposes of Rule 436(g)(2) of the
Rules and Regulations and (ii) no such organization shall have publicly
announced that it has under surveillance or review, with      

                                       31
<PAGE>
 
    
possible negative implications, its rating of the Company's senior debt
securities.      
    
     (l)  Subsequent to the execution and delivery of this Agreement there shall
not have occurred any of the following: (i) trading in securities generally on
the New York Stock Exchange or the American Stock Exchange or in the over-the-
counter market, or trading in any securities of the Company on any exchange or
in the over-the-counter market, shall have been suspended or minimum prices
shall have been established on any such exchange or such market by the
Commission, by such exchange or by any other regulatory body or governmental
authority having jurisdiction, (ii) a banking moratorium shall have been
declared by federal or state authorities, (iii) the United States shall have
become engaged in hostilities, there shall have been an escalation in
hostilities involving the United States or there shall have been a declaration
of a national emergency or war by the United States, the effect of which on the
financial markets in the United States would make it, in the judgment of a
majority in interest of the several Underwriters, impracticable or inadvisable
to proceed with the public offering or delivery of the Notes on the terms and in
the manner contemplated by the Prospectus or (iv) there shall have occurred such
a material adverse change in general economic or financial conditions (or the
effect of international conditions on the financial markets in the United States
shall be such) as to make it, in the judgment of a majority in interest of the
several Underwriters, impractical or inadvisable to proceed with the public
offering or delivery of the Notes on the terms and in the manner contemplated
in the Prospectus.      

     All opinions, letters, evidence and certificates mentioned above or
elsewhere in this Agreement shall be deemed to be in compliance with the
provisions hereof only if they are in form and substance satisfactory to counsel
for the Underwriters.
    
     8.  Indemnification and Contribution.  (a) The Company shall indemnify and
         --------------------------------
hold harmless each Underwriter and each person, if any, who controls any
Underwriter within the meaning of the Securities Act, from and against any loss,
claim, damage or liability, joint or several, and any action in respect thereof
(including, but not limited to, any loss, claim, damage, liability or      

                                       32
<PAGE>
 
    
action relating to purchases and sales of the Notes), to which that
Underwriter or controlling person may become subject, under the Securities Act
or otherwise, insofar as such loss, claim, damage, liability or action arises
out of, or is based upon, (i) any untrue statement or alleged untrue statement
of a material fact contained in any Preliminary Prospectus, the Registration
Statement or the Prospectus or in any amendment or supplement thereto or (ii)
the omission or alleged omission to state therein a material fact required to
be stated therein or necessary to make the statements therein, with respect to
any Preliminary Prospectus or the Prospectus, in the light of the
circumstances under which they were made, not misleading, and shall reimburse
each Underwriter and each such controlling person promptly upon demand for any
legal or other expenses reasonably incurred by that Underwriter or controlling
person in connection with investigating or defending or preparing to defend
against any such loss, claim, damage, liability or action; provided, however,
that the Company shall not be liable in any such case to the extent that any
such loss, claim, damage, liability or action arises out of, or is based upon,
any untrue statement or alleged untrue statement or omission or alleged
omission made in any Preliminary Prospectus, the Registration Statement or the
Prospectus or in any such amendment or supplement in reliance upon and in
conformity with written information furnished to the Company through the
Representatives by or on behalf of any Underwriter specifically for inclusion
therein; and provided, further, that as to any Preliminary Prospectus or
Prospectus, this indemnity agreement shall not inure to the benefit of any
Underwriter or any person controlling that Underwriter on account of any loss,
claim, damage, liability or action arising from the sale of Notes to any
person by that Underwriter if that Underwriter failed to send or give a copy
of the Prospectus, as the same may be amended or supplemented, to that person
within the time required by the Securities Act, and the untrue statement or
alleged untrue statement of a material fact or omission or alleged omission to
state a material fact in such Preliminary Prospectus was corrected in the
Prospectus and such document was made available to the Underwriters prior to
the sale of such Notes. For purposes of the last proviso to the immediately
preceding sentence, the term "Prospectus" shall not be deemed to include the
documents incorporated therein by reference, and no Underwriter shall be
obligated to send      

                                       33
<PAGE>
 
or give any supplement or amendment to any document incorporated by reference
in any preliminary Prospectus or the Prospectus to any person other than a
person to whom such Underwriter had delivered such incorporated document or
documents in response to a written request therefor. The foregoing indemnity
agreement is in addition to any liability which the Company may otherwise have
to any Underwriter or to any controlling person of that Underwriter.
    
     (b)  Each Underwriter, severally and not jointly, shall indemnify and hold
harmless the Company, each of its directors, officers, employees and agents
and each person, if any, who controls the Company within the meaning of the
Securities Act, from and against any loss, claim, damage or liability, joint
or several, and any action in respect thereof, to which the Company or any
such director, officer, employee, agent or controlling person may become
subject, under the Securities Act or otherwise, insofar as such loss, claim,
damage, liability or action arises out of, or is based upon, (i) any untrue
statement or alleged untrue statement of a material fact contained in any
Preliminary Prospectus, the Registration Statement or the Prospectus or in any
amendment or supplement thereto or (ii) the omission or alleged omission to
state therein a material fact required to be stated therein or necessary to
make the statements therein, in respect of any Preliminary Prospectus or the
Prospectus, in the light of the circumstances under which they were made, not
misleading, but in each case only to the extent that the untrue statement or
alleged untrue statement or omission or alleged omission was made in reliance
upon and in conformity with written information furnished to the Company
through the Representatives by or on behalf of such Underwriter specifically
for inclusion therein, and shall reimburse the Company and any such director,
officer, employee, agent or controlling person promptly upon demand for any
legal or other expenses reasonably incurred by the Company or any such
director, officer, employee, agent or controlling person in connection with
investigating or defending or preparing to defend against any such loss,
claim, damage, liability or action . The foregoing indemnity agreement is in
addition to any liability which any Underwriter may otherwise have to the
Company or any such director, officer or controlling person.      

                                       34
<PAGE>
 
    
     (c)  Promptly after receipt by an indemnified party under this Section 8 of
notice of any claim or the commencement of any action, the indemnified party
shall, if a claim in respect thereof is to be made against the indemnifying
party under this Section 8, notify the indemnifying party in writing of the
claim or the commencement of that action (enclosing a copy of all papers
served); provided, however, that the failure to notify the indemnifying party
shall not relieve it from any liability which it may have under this Section 8
except to the extent it has been materially prejudiced by such failure and,
provided, further, that the failure to notify the indemnifying party shall not
relieve it from any liability which it may have to an indemnified party
otherwise than under this Section 8. If any such claim or action shall be
brought against an indemnified party, and it shall notify the indemnifying
party thereof, the indemnifying party shall be entitled to participate therein
and, to the extent that it wishes, jointly with any other similarly notified
indemnifying party, to assume the defense thereof with counsel reasonably
satisfactory to the indemnified party. After notice from the indemnifying
party to the indemnified party of its election to assume the defense of such
claim or action, the indemnifying party shall not be liable to the indemnified
party under this Section 8 for any legal or other expenses subsequently
incurred by the indemnified party in connection with the defense thereof other
than reasonable costs of investigation; provided, however, that the
indemnified party shall have the right to employ counsel to represent the
indemnified party and their respective controlling persons who may be subject
to liability arising out of any claim in respect of which indemnity may be
sought by the indemnified party against the indemnifying party under this
Section 8 if the employment of such counsel shall have been authorized in
writing by the indemnifying party in connection with the defense of such
action or, if in the written opinion of counsel to either the indemnifying
party or the indemnified party, representation of both parties by the same
counsel would be inappropriate due to actual or likely conflicts of interest
between them, and in that event the fees and expenses of one firm of separate
counsel (in addition to the fees and expenses of local counsel) shall be paid
by the indemnifying party. The indemnifying party shall not be liable for any
settlement of any proceeding effected without its written consent.      

                                       35
<PAGE>
 
    
     (d)  If the indemnification provided for in this Section 8 shall for any
reason be unavailable to or insufficient to hold harmless an indemnified party
under Section 8(a) or 8(b) in respect of any loss, claim, damage or liability,
or any action in respect thereof, referred to therein, then each indemnifying
party shall, in lieu of indemnifying such indemnified party, contribute to the
amount paid or payable by such indemnified party as a result of such loss,
claim, damage or liability, or action in respect thereof, (i) in such
proportion as shall be appropriate to reflect the relative benefits received
by the Company on the one hand and the Underwriters on the other from the
offering of the Notes or (ii) if the allocations provided by clause (i) above
is not permitted by applicable law, in such proportion as is appropriate to
reflect not only the relative benefits referred to in clause (i) above but
also the relative fault of the Company on the one hand and the Underwriters on
the other with respect to the statements or omissions which resulted in such
loss, claim, damage or liability, or action in respect thereof, as well as any
other relevant equitable considerations. The relative benefits received by the
Company on the one hand and the Underwriters on the other with respect to such
offering shall be deemed to be in the same proportion as the total net
proceeds from the offering of the Notes purchased under this Agreement (before
deducting expenses) received by the Company bear to the total underwriting
discounts, fees and commissions received by the Underwriters with respect to
the Notes purchased under this Agreement, on the other hand. The relative
fault shall be determined by reference to whether the untrue or alleged untrue
statement of a material fact or omission or alleged omission to state a
material fact relates to information supplied by the Company or the
Underwriters, the intent of the parties and their relative knowledge, access
to information and opportunity to correct or prevent such statement or
omission. The Company and the Underwriters agree that it would not be just and
equitable if contributions pursuant to this Section 8(d) were to be determined
by pro rata allocation (even if the Underwriters were treated as one entity
for such purpose) or by any other method of allocation which does not take
into account the equitable considerations referred to herein. The amount paid
or payable by an indemnified party as a result of the loss, claim, damage or
liability, or action in respect thereof, referred to above in this Section 
     

                                       36
<PAGE>
 
    
8(d) shall be deemed to include, for purposes of this Section 8(d), any legal
or other expenses reasonably incurred by such indemnified party in connection
with investigating or defending any such action or claim pursuant to Section
8(c) above. Notwithstanding the provisions of this Section 8(d), no
Underwriter shall be required to contribute any amount in excess of the amount
by which the total price at which the Notes underwritten by it and distributed
to the public was offered to the public exceeds the amount of any damages
which such Underwriter has otherwise paid or become liable to pay by reason of
any untrue or alleged untrue statement or omission or alleged omission. No
person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Securities Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation. The Underwriters'
obligations to contribute as provided in this Section 8(d) are several in
proportion to their respective underwriting obligations and are not joint. 
     

     (e)  The Underwriters severally confirm that the statements with respect to
the public offering of the Notes set forth on the cover page of, and under the
caption "Underwriting" in, the Prospectus are correct and constitute the only
information furnished in writing to the Company by or on behalf of the
Underwriters specifically for inclusion in the Registration Statement and the
Prospectus.
    
     9.  Defaulting Underwriters.  If, on the Delivery Date, any Underwriter
         -----------------------
defaults in the performance of its obligations under this Agreement, the
remaining non-defaulting Underwriters shall be obligated to purchase the
principal amount of Notes which the defaulting Underwriter agreed but failed to
purchase on the Delivery Date in the respective proportions which the principal
amount of the Notes set forth opposite the name of each remaining non-defaulting
Underwriter in Schedule 1 hereto bears to the aggregate principal amount of the
Notes set forth opposite the names of all the remaining non-defaulting
Underwriters in Schedule 1 hereto; provided, however, that the remaining non-
defaulting Underwriters shall not be obligated to purchase any Notes on the
Delivery Date if the principal amount of the Notes which the defaulting
Underwriter or Underwriters agreed but failed to purchase on such date exceeds
10.0% of      

                                       37
<PAGE>
 
    
the aggregate principal amount of the Notes to be purchased on the Delivery
Date. If the foregoing maximum is exceeded, the remaining non-defaulting
Underwriters, or those other underwriters satisfactory to the Representatives
who so agree, shall have the right, but shall not be obligated, to purchase,
in such proportion as may be agreed upon among them, all the Notes to be
purchased on the Delivery Date. If the remaining Underwriters or other
underwriters satisfactory to the Representatives do not elect to purchase the
principal amount of the Notes which the defaulting Underwriter or Underwriters
agreed but failed to purchase on the Delivery Date, this Agreement shall
terminate without liability on the part of any non-defaulting Underwriter or
the Company, except that the Company shall continue to be liable for the
payment of expenses to the extent set forth in Sections 6 and 11. As used in
this Agreement, the term "Underwriter" includes, for all purposes of this
Agreement unless the context requires otherwise, any party not listed in
Schedule 1 hereto who, pursuant to this Section 9, purchases Notes which a
defaulting Underwriter agreed but failed to purchase.      

     Nothing contained herein shall relieve a defaulting Underwriter of any
liability it may have to the Company for damages caused by its default.  If
other underwriters are obligated or agree to purchase the Notes of a defaulting
or withdrawing Underwriter, either the Representatives or the Company may
postpone the Delivery Date for up to seven full business days in order to effect
any changes that in the opinion of counsel for the Company or counsel for the
Underwriters may be necessary in the Registration Statement, the Prospectus or
in any other document or arrangement.
    
     10.  Termination.  The obligations of the Underwriters hereunder may be
          -----------
terminated by the Representatives by notice given to and received by the Company
prior to delivery of and payment for the Notes if, prior to that time, any of
the events described in Section 7(k) or 7(l) shall have occurred or if the
Underwriters shall decline to purchase the Notes for any reason permitted under
this Agreement.      
    
     11.  Reimbursement of Underwriters' Expenses.  If (a)  the Underwriters
          ---------------------------------------
shall decline to purchase the Notes because of the occurrence of any of the
events      

                                       38
<PAGE>
 
    
described in Section 7(k) or 7(l) or (b) the sale of the Notes is not
consummated by reason of the failure by the Company to perform any material
obligation or satisfy any material condition under this Agreement, the Company
shall reimburse the Underwriters for the reasonable fees and expenses of their
counsel and for such other reasonable out-of-pocket expenses as shall have been
incurred by them in connection with this Agreement and the proposed purchase of
the Notes, and upon demand the Company shall pay the full amount thereof to the
Representatives; provided that, the aggregate amount to be reimbursed shall not
exceed $400,000 (or $350,000 if the Underwriters shall decline to purchase the
Notes because of the occurrence of any of the events described in Sections 7(k)
or 7(l)).  If this Agreement is terminated pursuant to Section 9 by reason of
the default of one or more Underwriters, the Company shall not be obligated to
reimburse any defaulting Underwriter on account of those expenses.      

     12.  Notices, etc.  All statements, requests, notices and agreements
          ------------
hereunder shall be in writing, and:

         (a)  if to the Underwriters, shall be delivered or sent by mail,

Underwriter at its address set forth in its acceptance telex to the
Representatives, which address shall be supplied to any other party hereto by
the Representatives upon request. Any such statements, requests, notices or
agreements shall take effect at the time of receipt thereof. The Company shall
be entitled to act and rely upon any request, consent, notice or agreement
given or made on

respective successors.  This Agreement and the terms and provisions hereof are

warranties, indemnities and agreements of the Company contained in this
Agreement shall also be deemed to be for the benefit of the person or persons,

Securities Act and (b) the indemnity agreement of the Underwriters contained in
Section 8(b) of this Agreement shall be deemed to be for the benefit of
directors, officers, employees and agents of the Company and any person
controlling the Company within the meaning of Section 15 of the Securities Act.

other than the persons referred to in this Section 13, any legal or equitable
right, remedy or claim under or in respect of this Agreement or any provision
contained herein.      

     14.  Survival.  The respective indemnities, representations, warranties and
          --------
agreements of the Company and the Underwriters contained in this Agreement or
made by or on behalf of them, respectively, pursuant to this Agreement, shall
survive the delivery of and payment for the Notes and shall remain in full force
and effect, regardless of any investigation made by or on behalf of any of them
or any person controlling any of them.

     15.  Definition of the Term "Business Day".  For purposes of this
          ------------------------------------
Agreement, "business day" means any day on which the New York Stock Exchange,

Section 102.  Compliance Certificates and Opinions.
              ------------------------------------ 

     Upon any application or request by the Company to the Trustee to take any
action under any provision of this Indenture, the Company shall furnish to the
Trustee such certificates and opinions as may be required under the Trust
Indenture Act.  Each such certificate or opinion shall be given in the form of
an Officers' Certificate, if to be given by an officer of the Company, or an
Opinion of Counsel, if to be given by counsel, and shall comply with the
requirements of the Trust Indenture Act and any other requirement set forth in
this Indenture.

     Every certificate or opinion with respect to compliance with a condition or
covenant provided for in this Indenture shall include

   (1) a statement that each individual signing such certificate or opinion
   has read such covenant or condition and the definitions herein relating
   thereto;

                                      -42-
<PAGE>
 
   (2) a brief statement as to the nature and scope of the examination or
   investigation upon which the statements or opinions contained in such
   certificate or opinion are based;

   (3) a statement that, in the opinion of each such individual, he has made
   such examination or investigation as is necessary to enable him to express
   an informed opinion as to whether or not such covenant or condition has
   been complied with; and

   (4) a statement as to whether, in the opinion of each such individual, such
   condition or covenant has been complied with.

Section 103.  Form of Documents Delivered to Trustee.
              -------------------------------------- 
    
     If several matters are required to be certified by, or covered by an
opinion of, any specified Person, it is not necessary that all such matters be
certified by, or covered by the opinion of, only one such Person, or that they
be so certified or covered by only one document, but one such Person may certify
or give an opinion with respect to some matters and one or more other such
Persons as to other matters, and any such Person may certify or give an opinion
as to such matters in one or several documents.      

     Any certificate or opinion of an officer of the Company may be based,
insofar as it relates to legal matters, upon a certificate or opinion of, or
representations by, counsel, unless such officer knows, or in the exercise of
reasonable care should know, that the certificate or opinion or representations
with respect to the matters upon which his certificate or opinion is based are
erroneous. Any such certificate or opinion of counsel may be based, insofar as
it relates to factual matters, upon a certificate or opinion of, or
representations by, an officer or officers of the Company stating that the
information with respect to such factual matters is in the possession of the
Company, unless such counsel knows, or in the exercise of reasonable care
should know, that the certificate or opinion or representations with respect
to such matters are erroneous.

     If any Person is required to make, give or execute two or more
applications, requests, consents, certificates, statements, opinions or other
instruments under this Indenture, they may, but need not, be consolidated and
form one instrument.      

Section 104.  Acts of Holders; Record Dates.
              ----------------------------- 
    
     Any request, demand, authorization, direction, notice, consent, waiver or
other action provided or permitted by this Indenture to be given or taken by
Holders may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such Holders in person or by an agent duly
appointed in writing; and, except as herein otherwise expressly provided, such
action shall become effective when such instrument or instruments are delivered
to the Trustee and, if it is hereby expressly required, to the Company.  Such
instrument or instruments (and the action embodied therein and evidenced
thereby) are herein sometimes referred to as the "Act" of the Holders signing
such instrument or instruments.  Proof of execution of any such instrument or of
a writing appointing any such agent shall be sufficient for any purpose of this
Indenture and (subject to Section 601) conclusive in favor of the Trustee and
the Company, if made in the manner provided in this Section 104.      
    
     The fact and date of the execution by any Person of any such instrument or
writing may be proved by the affidavit of a witness of such execution or by a
certificate of a notary public or other officer authorized by law to take
acknowledgments of deeds, certifying that the individual signing such
instrument or writing acknowledged to him the execution thereof. If such
execution is by a signer acting in a capacity other than his individual
capacity, such certificate or affidavit shall also constitute sufficient proof
of his authority. The fact and date of the execution of any such instrument or
writing, or the authority of the Person executing the same, may also be proved
in any other manner that the Trustee deems sufficient.      

     The ownership of Securities shall be proved by the Security Register.

                                      -44-
<PAGE>
 
     Any request, demand, authorization, direction, notice, consent, waiver or
other Act of the Holder of any Security shall bind every future Holder of the
same Security and the Holder of every Security issued upon the registration of
transfer thereof or in exchange therefor or in lieu thereof in respect of
anything done, omitted or suffered to be done by the Trustee or the Company in
reliance thereon, whether or not notation of such action is made upon such
Security.

     The Company may set any day as a record date for the purpose of determining
the Holders of Outstanding Securities entitled to give or take any request,
demand, authorization, direction, notice, consent, waiver or other action
provided or permitted by this Indenture to be given or taken by Holders of
Securities, provided that the Company may not set a record date for, and the
            --------                                                        
provisions of this paragraph shall not apply with respect to, the giving or
making of any notice, declaration, request or direction referred to in the next
paragraph.  If any record date is set pursuant to this paragraph, the Holders of
Outstanding Securities on such record date, and no other Holders, shall be
entitled to take the relevant actions whether or not such Holders remain Holders
after such record date; provided that no such action shall be effective
                        --------                                       
hereunder unless taken on or prior to the applicable Record Expiration Date by
Holders of the requisite principal amount of Outstanding Securities on such
record date; and provided further that for the purpose of determining whether
                 -------- -------                                            
Holders of the requisite principal amount of such Securities have taken
such action, no Security shall be deemed to have been Outstanding on such record
date unless it is also Outstanding on the date such action is to become
effective.  Nothing in this paragraph shall prevent the Company from setting a
new record date for any action for which a record date has previously been set
pursuant to this paragraph (whereupon the record date previously set shall
automatically and with no action by any Person be cancelled and of no effect),
nor shall anything in this paragraph be construed to render ineffective any
action taken by Holders of the requisite principal amount of Outstanding
Securities on the date such action is taken.  Promptly after any record date is
set pursuant to this paragraph, the Company, at its own expense, shall cause

                                      -45-
<PAGE>
 
    
notice of such record date, the proposed action by Holders and the applicable
Record Expiration Date to be given to the Trustee in writing and to each Holder
of Securities in the manner set forth in Section 106 .      
    
     The Trustee may set any day as a record date for the purpose of determining
the Holders of Outstanding Securities entitled to join in the giving or making
of (i) any Notice of Default, (ii) any declaration of acceleration referred to
in Section 502, (iii) any request to institute proceedings referred to in
Section 507(2) or (iv) any direction referred to in Section 512.  If any record
date is set pursuant to this paragraph, the Holders of Outstanding Securities on
such record date, and no other Holders, shall be entitled to join in such
notice, declaration, request or direction, whether or not such Holders remain
Holders after such record date; provided that no such action shall be effective
                                --------                                       
hereunder unless taken on or prior to the applicable Record Expiration Date by
Holders of the requisite principal amount of Outstanding Securities on such
record date; and provided further that for the purpose of determining whether
                 -------- -------                                            
Holders of the requisite principal amount of such Securities have taken such
action, no Security shall be deemed to have been Outstanding on such record date
unless it is also Outstanding on the date such action is to become effective.
Nothing in this paragraph shall be construed to prevent the Trustee from
setting a new record date for any action (whereupon the record date previously
set shall automatically and without any action by any Person be cancelled and
of no effect), nor shall anything in this paragraph be construed to render
ineffective any action taken by Holders of the requisite principal amount of
Outstanding Securities on the date such action is taken. Promptly after any
record date is set pursuant to this paragraph, the Trustee, at the Company's
expense, shall cause notice of such record date, the matter(s) to be submitted
for potential action by Holders and the applicable Record Expiration Date to
be given to the Company in writing and to each Holder of Securities in the
manner set forth in Section 106.      

     With respect to any record date set pursuant to this Section 104, the party
hereto that sets such record date may designate any day as the "Record
Expiration Date" and 

                                      -46-
<PAGE>
 
    
from time to time may change the Record Expiration Date to
any earlier or later day, provided that no such change shall be effective unless
                          --------                                              
notice of the proposed new Record Expiration Date is given to the other party
hereto in writing, and to each Holder of Securities in the manner set forth in
Section 106, on or before the existing Record Expiration Date.  If a Record
Expiration Date is not designated with respect to any record date set pursuant
to this Section 104, the party hereto that set such record date shall be deemed
to have initially designated the 180th day after such record date as the Record
Expiration Date with respect thereto, subject to its right to change the Record
Expiration Date as provided in this paragraph.  Notwithstanding the foregoing,
no Record Expiration Date shall be later than the 180th day after the applicable
record date.      

     Without limiting the foregoing, a Holder entitled hereunder to take any
action hereunder with regard to any particular Security may do so with regard to
all or any part of the principal amount of such Security or by one or more duly
appointed agents each of which may do so pursuant to such appointment with
regard to all or any part of such principal amount.

Section 105.  Notices, Etc., to Trustee and Company.
              ------------------------------------- 

     Any request, demand, authorization, direction, notice, consent, waiver or
Act of Holders or other document provided or permitted by this Indenture to be
made upon, given or furnished to, or filed with,

     (1) the Trustee by any Holder or by the Company shall be sufficient for
     every purpose hereunder if made, given, furnished or filed in writing and
     mailed, first-class postage prepaid, to or with the Trustee at its
     Corporate Trust Office, Attention: Corporate Trust Administration, or

     (2) the Company by the Trustee or by any Holder shall be sufficient for
     every purpose hereunder (unless otherwise herein expressly provided) if
     in writing and mailed, first-class postage prepaid, to the Company
     addressed to it at the address of its principal office specified in the
     first paragraph of 

                                      -47-

     this Indenture, Attention: General Counsel, or at any other address
     previously furnished in writing to the Trustee by the Company.

Section 106.  Notice to Holders; Waiver.
              ------------------------- 
    
     When this Indenture provides for notice to Holders of any event, such
notice shall be sufficiently given (unless otherwise herein expressly provided)
if in writing and mailed, first-class postage prepaid, to each Holder affected
by such event, at such Holder's address as it appears in the Security Register,
not later than the latest date (if any), and not earlier than the earliest date
(if any), prescribed for the giving of such notice.  Neither the failure to
mail or give such notice as otherwise provided herein, nor any defect in any
notice so mailed or given to any particular Holder shall affect the sufficiency
of such notice with respect to other Holders.  When this Indenture provides
for notice in any manner, such notice may be waived in writing by the Person
entitled to receive such notice, either before or after the event, and such
waiver shall be the equivalent of such notice. Waivers of notice by Holders
shall be filed with the Trustee, but such filing shall not be a condition
precedent to the validity of any action taken in reliance upon such waiver.
    
     In case by reason of the suspension of regular mail service or by reason of
any other cause it shall be impracticable to give such notice by mail, then such
notification as shall be made with the approval of the Trustee shall constitute
a sufficient notification for every purpose hereunder.

Section 107.  Conflict with Trust Indenture Act.
              --------------------------------- 

     If any provision hereof limits, qualifies or conflicts with a provision of
the Trust Indenture Act that is required under such Act to be part of and govern
this Indenture, the latter provision shall control.  If any provision of this
Indenture modifies or excludes any provision of the Trust Indenture Act that may
be so modified or excluded, the latter provision shall be deemed to apply to
this Indenture as so modified or to be excluded, as the case may be.

Section 203.  Form of Reverse of Security.
              --------------------------- 
    
     This Security is one of a duly authorized issue of Securities of the
Company designated as its _____% Senior Discount Notes due 2004 (herein called
the "Securities"), limited in aggregate principal amount at final Stated
Maturity to $___________, issued and to be issued under an Indenture, dated as

hereby made to the Indenture for a statement of the respective rights,
limitations of rights, duties and immunities thereunder of the Company, the
Trustee and the Holders of the Securities and of the terms upon which the
Securities are, and are to be, authenticated and delivered.      
    
     The Securities are subject to redemption upon not less than 30 nor more
than 60 days' notice by mail, at any time on or after January 15, 1999 and prior

together in the case of any such redemption with accrued interest, if any, to
the Redemption Date, but interest installments whose Stated Maturity is on or
prior to such Redemption Date shall be payable to the Holders of such
Securities, or one or more predecessor Securities, of record at the close of
business on the relevant Record Dates referred to on the face hereof, all as
provided in the Indenture.      

          The Securities do not have the benefit of any sinking fund
obligations.
    
          Upon the occurrence of both a Change of Control and a Rating Decline,
the Company shall be required to make an Offer to Purchase all or a specified
portion of the Securities at a Purchase Price in cash equal to (a) 101 percent
of the Accreted Value thereof on any Purchase Date occurring prior to January
15, 1997 or (b) 101 percent of the principal amount thereof on any Purchase
Date occurring on or after January 15, 1997 plus accrued and unpaid interest, if
any, to such Purchase Date.  If the Company or any Restricted Subsidiary
consummates an Asset Sale, under certain circumstances, the Company shall be
required to make an Offer to Purchase up to all or a specified portion of the
Securities at a Purchase Price in cash equal to (a) 100 percent of the Accreted
Value thereof on any Purchase Date occurring prior to the January 15, 1997 or
(b) 100 percent of the principal amount thereof on any Purchase Date occurring
on or after January 15, 1997, plus accrued and unpaid interest, if any, to such
Purchase Date, in an amount equal to any Net Cash Proceeds from such an Asset
Sale that are not used to reinvest in the business of the Company and/or repay
in a permanent reduction of Debt of the Company or Debt of its Restricted
Subsidiaries and Eligible Joint Ventures. Holders of Securities shall receive
notice of any such Offer to Purchase from the Company prior to the related
Purchase Date and may elect to have such       

                                      -55-
<PAGE>
 
Securities purchased by completing the form entitled "Option of Holder to
Elect Purchase" appearing on the reverse side of the Security.
    
          In the event of redemption, or purchase pursuant to an Offer to
Purchase, of this Security in part only, a new Security or Securities for the
portion hereof not redeemed or purchased shall be issued in the name of the
Holder hereof upon the cancellation hereof.      
    
          The Indenture contains provisions for defeasance at any time of the
entire Debt of this Security or certain restrictive covenants and Events of
Default with respect to this Security, including, without limitation, covenants
relating to Offers to Purchase, in each case upon compliance with certain
conditions set forth in the Indenture.      
    
          If an Event of Default shall occur and be continuing, there may be
declared due and payable the Default Amount of the Securities, in the manner and
with the effect provided in the Indenture.  Until January 15, 1997, the Default
Amount in respect of this Security as of the date upon which the Securities are
declared due and payable shall equal the Accreted Value of this Security as of
such date.  On and after January 15, 1997, the Default Amount in respect of this
Security as of any particular date shall equal 100% of the principal amount of
this Security plus accrued and unpaid interest, if any, to such date.      
    
          The Indenture permits, with certain exceptions as therein provided,
the amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Securities under the Indenture at
any time by the Company and the Trustee with the consent of the Holders of a
majority in aggregate principal amount of the Securities at the time
Outstanding.  The Indenture also contains provisions permitting the Holders of
specified percentages in aggregate principal amount of the Securities at the
time Outstanding, on behalf of the Holders of all the Securities, to waive
compliance by the Company with certain provisions of the Indenture and certain
past defaults under the Indenture and their consequences. In addition,      

                                      -56-
<PAGE>
 
    
without the consent of any Holder of a Security, the Indenture and the
Securities may be amended and supplemented to cure any ambiguity or
inconsistency, make other changes that shall not adversely affect the rights
of the Holders or certain other matters specified in the Indenture. Any such
consent or waiver by the Holder of this Security shall be conclusive and
binding upon such Holder and upon all future Holders of this Security and of
any Security issued upon the registration of transfer hereof or in exchange
herefor or in lieu hereof, whether or not notation of such consent or waiver
is made upon this Security.      
    
          As provided in and subject to the provisions of the Indenture, the
Holder of this Security shall not have the right to institute any proceeding
with respect to the Indenture or for the appointment of a receiver, or trustee
or for any other remedy thereunder, unless such Holder shall have previously
given the Trustee written notice of a continuing Event of Default with respect
to the Securities, the Holders of not less than 25 percent in principal amount
of the Securities at the time Outstanding shall have made written request to the
Trustee to institute proceedings in respect of such Event of Default as Trustee
and offered the Trustee reasonable indemnity, and the Trustee shall not have
received from the Holders of a majority in principal amount of Securities at
the time Outstanding a direction inconsistent with such request and shall have
failed to institute any such proceeding for  60 days after receipt of such
notice, request and offer of indemnity.  The foregoing shall not apply to
certain suits described in the Indenture, including any suit instituted by the
Holder of this Security for the enforcement of any payment of principal hereof
or any premium or interest hereon on or after the respective due dates
expressed herein (or, in the case of redemption, on or after the Redemption
Date or, in the case of any purchase of this Security required to be made
pursuant to an Offer to Purchase, on or after the Purchase Date).     

          No reference herein to the Indenture and no provision of this Security
or of the Indenture shall alter or impair the obligation of the Company, which
is absolute and unconditional, to pay the principal of (and premium, 

                                      -57-
<PAGE>
 
if any) and interest on this Security at the times, place and rate, and in the
coin or currency, herein prescribed.
    
          As provided in the Indenture and subject to certain limitations
therein set forth, the transfer of this Security is registrable in the Security
Register, upon surrender of this Security for registration of transfer at the
office or agency of the Company in the Borough of Manhattan, The City of New
York, (which initially  shall be the corporate trust office of the Trustee),
duly endorsed by, or accompanied by a written instrument of transfer in form
satisfactory to the Company and the Security Registrar duly executed by, the
Holder hereof or his attorney duly authorized in writing, and thereupon one or
more new Securities, of authorized denominations and for the same aggregate
principal amount, shall be issued to the designated transferee or transferees.
     
          The Securities are issuable only in registered form without coupons in
denominations of $1,000 and any integral multiple thereof.  As provided in the
Indenture and subject to certain limitations therein set forth, Securities are
exchangeable for a like aggregate principal amount of Securities of like tenor
of a different authorized denomination, as requested by the Holder surrendering
the same.

          No service charge shall be made for any such registration of transfer
or exchange, but the Company may require payment of a sum sufficient to cover
any tax or other governmental charge payable in connection therewith.

          A director, officer, employee, stockholder or incorporator of the
Company shall not have any liability for any obligations of the Company under
this Security or the Indenture or for any claim based on, in respect of or by
reason of such obligations or their creation. Each Holder by accepting this
Security waives and releases all such liability. Such waiver and release are
part of the consideration for the issuance of this Security.

          Prior to due presentment of this Security for registration of
transfer, the Company, the Trustee and any agent of the Company or the Trustee
may treat the Person 

                                      -58-
<PAGE>
 
    
in whose name this Security is registered as the owner hereof for all
purposes, whether or not this Security is overdue, and neither the Company,
the Trustee nor any such agent shall be affected by notice to the contrary. 
     
    
          Interest on this Security shall be computed on the basis of a 360-day
year of 12 30-day months.      
    
          All terms used in this Security that are defined in the Indenture
shall have the meanings assigned to them in the Indenture.      

          The Indenture and this Security shall be governed by and construed in
accordance with the laws of the State of New York, as applied to contracts made
and performed under the State of New York, without regard to principles of
conflicts of law.

     The Securities shall be executed on behalf of the Company by its Chairman

and delivery of such Securities; and the Trustee in accordance with such Company

     Each Security shall be dated the date of its authentication.

     No Security shall be entitled to any benefit under this Indenture or be
valid or obligatory for any purpose unless there appears on such Security a
certificate of authentication substantially in the form provided for herein
executed by the Trustee by manual signature, and such certificate upon any
Security shall be conclusive evidence, and the only evidence, that such
Security has been duly authenticated and delivered hereunder.

                                      -63-

     Pending the preparation of definitive Securities, the Company may execute,
and upon Company Order the Trustee shall authenticate and deliver, temporary
Securities that are printed, lithographed, typewritten, mimeographed or
otherwise produced, in any authorized denomination, substantially of the tenor
of the definitive Securities in lieu of which they are issued and with such
appropriate insertions, omissions, substitutions and other variations as the
officers executing such Securities may determine, as evidenced by their
execution of such Securities.      
    
     If temporary Securities are issued, the Company shall cause definitive
Securities to be prepared without unreasonable delay.  After the preparation of
definitive Securities, the temporary Securities shall be exchangeable for
definitive Securities upon surrender of the temporary Securities at any office
or agency of the Company designated pursuant to Section 1002 without charge to
the Holder.  Upon surrender for cancellation of any one or more temporary
Securities, the Company shall execute and the Trustee shall authenticate and
deliver in exchange therefor a like principal amount of definitive Securities of
authorized denominations and of a like tenor.  Until so exchanged, the temporary
Securities shall in all respects be entitled to the same benefits under this
Indenture as definitive Securities.      

Section 305.  Registration, Registration of Transfer and Exchange.
              --------------------------------------------------- 
    
     The Company shall cause to be kept at the Corporate Trust Office of the
Trustee a register (the register maintained in such office and in any other
office or agency designated pursuant to Section 1002  being herein sometimes
collectively referred to as the "Security Register") in which, subject to such
reasonable regulations as it may prescribe, the Company shall provide for the
registration of Securities and of transfers of Securities. The Trustee is
hereby appointed "Security Registrar" for the purpose of registering
Securities and transfers of Securities as herein provided.      

     Upon surrender for registration of transfer of any Security at an office or
agency of the Company designated 

                                      -64-
<PAGE>
 
    
pursuant to Section 1002 for such purpose, the Company shall execute, and the
Trustee shall authenticate and deliver, in the name of the designated
transferee or transferees, one or more new Securities of any authorized
denominations and of a like aggregate principal amount and tenor.      
    
     At the option of the Holder, Securities may be exchanged for other
Securities of any authorized denominations and of a like aggregate principal
amount and tenor, upon surrender of the Securities to be exchanged at such
office or agency.  Whenever any Securities are so surrendered for exchange, the
Company shall execute, and the Trustee shall authenticate and deliver, the
Securities that the Holder making the exchange is entitled to receive.      

     All Securities issued upon any registration of transfer or exchange of
Securities shall be the valid obligations of the Company, evidencing the same
debt, and entitled to the same benefits under this Indenture, as the Securities
surrendered upon such registration of transfer or exchange.

     Every Security presented or surrendered for registration of transfer or for
exchange shall (if so required by the Company or the Trustee) be duly endorsed,
or be accompanied by a written instrument of transfer in form satisfactory to
the Company and the Security Registrar duly executed, by the Holder thereof or
his attorney duly authorized in writing.
    
     No service charge shall be made for any registration of transfer or
exchange of Securities, but the Company may require payment of a sum
sufficient to cover any tax or other governmental charge that may be imposed
in connection with any registration of transfer or exchange of Securities,
other than exchanges pursuant to Section 304, 906 or 1108 or in accordance
with any Offer to Purchase pursuant to Section 1013 or 1015 , and in any such
case not involving any transfer.      

     Neither the Trustee, the Security Registrar nor the Company shall be
required (i) to issue, register the transfer of or exchange any Security during
a period 

                                      -65-
<PAGE>
 
    
beginning at the opening of business 15 days before the day of the mailing of
a notice of redemption of Securities selected for redemption under Section
1104 and ending at the close of business on the day of such mailing or (ii) to
register the transfer of or exchange any Security so selected for redemption
in whole or in part, except the unredeemed portion of any Security being
redeemed in part.     

Section 306.  Mutilated, Destroyed, Lost and Stolen  Securities.
              ------------------------------------------------- 

     If any mutilated Security is surrendered to the Trustee, the Company shall
execute and the Trustee shall authenticate and deliver in exchange therefor a
new Security of like tenor and principal amount and bearing a number not
contemporaneously outstanding.

     If there shall be delivered to the Company and the Trustee (i) evidence to
their satisfaction of the destruction, loss or theft of any Security and (ii)
such security or indemnity as may be required by them to save each of them and
any agent of either of them harmless, then, in the absence of notice to the
Company or the Trustee that such Security has been acquired by a bona fide
purchaser, the Company shall execute and upon its request the Trustee shall
authenticate and deliver, in lieu of any such destroyed, lost or stolen
Security, a new Security of like tenor and principal amount and bearing a number
not contemporaneously outstanding.

     In case any such mutilated, destroyed, lost or stolen Security has become
or is about to become due and payable, the Company in its discretion may, 
instead of issuing a new Security, pay such Security.

     Upon the issuance of any new Security under this Section, the Company may
require the payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in relation thereto and any other expenses (including
the fees and expenses of the Trustee) connected therewith.

     Every new Security issued pursuant to this Section 306 in lieu of any
destroyed, lost or stolen Security 

                                      -66-
<PAGE>
 
shall constitute an original additional contractual obligation of the Company,
whether or not the destroyed, lost or stolen Security shall be at any time
enforceable by anyone, and shall be entitled to all the benefits of this
Indenture equally and proportionately with any and all other Securities duly
issued hereunder.

     The provisions of this Section 306 are exclusive and shall preclude (to the
extent lawful) all other rights and remedies with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Securities.

Section 307.  Payment of Interest; Interest Rights Preserved.
              ---------------------------------------------- 
    
     Interest on any Security  that is payable and is punctually paid or duly
provided for on any Interest Payment Date shall be paid to the Person in whose
name that Security (or one or more Predecessor Securities) is registered at the
close of business on the Regular Record Date for such interest.      
    
     Any interest on any Security  that is payable but is not punctually paid or
duly provided for on any Interest Payment Date (herein called "Defaulted
Interest") shall forthwith cease to be payable to the Holder on the relevant
Regular Record Date by virtue of having been such Holder, and such Defaulted
Interest may be paid by the Company, at its election in each case, as provided
in clause (1) or (2) below:      

     (1)  The Company may elect to make payment of any Defaulted Interest to the
Persons in whose names the Securities (or their respective Predecessor
Securities) are registered at the close of business on a Special Record Date for
the payment of such Defaulted Interest, which shall be fixed in the following
manner.  The Company shall notify the Trustee in writing of the amount of
Defaulted Interest proposed to be paid on each Security and the date of the
proposed payment and at the same time the Company shall deposit with the Trustee
an amount of money equal to the aggregate amount proposed to be paid in respect
of such Defaulted Interest or shall make arrangements satisfactory to the
Trustee for such deposit prior to the date of the proposed payment, such money

                                      -67-
<PAGE>
 
    
when deposited to be held in trust for the benefit of the Persons entitled to
such Defaulted Interest as provided in this  clause.  Thereupon the Trustee
shall fix a Special Record Date for the payment of such Defaulted Interest  that
shall be not more than 15 days and not less than 10 days prior to the date of
the proposed payment and not less than 10 days after the receipt by the Trustee
of the notice of the proposed payment.  The Trustee shall promptly notify the
Company of such Special Record Date and, in the name and at the expense of the
Company, shall cause notice of the proposed payment of such Defaulted Interest
and the Special Record Date therefor to be given to each Holder in the manner
specified in Section 106 not less than 10 days prior to such Special Record
Date.  Notice of the proposed payment of such Defaulted Interest and the Special
Record Date therefor having been so given, such Defaulted Interest shall be
paid to the Persons in whose names the Securities (or their respective
Predecessor Securities) are registered at the close of business on such Special
Record Date and shall no longer be payable pursuant to the following clause
(2).      
    
     (2)  The Company may make payment of any Defaulted Interest in any other
lawful manner not inconsistent with the requirements of any securities exchange
on which the Securities may be listed, and upon such notice as may be required
by such exchange, if, after notice given by the Company to the Trustee of the
proposed payment pursuant to this clause, such manner of payment shall be
deemed practicable by the Trustee.      

     Subject to the foregoing provisions of this Section, each Security
delivered under this Indenture upon registration of transfer of or in exchange
for or in lieu of any other Security shall carry the rights to interest accrued
and unpaid, and to accrue, which were carried by such other Security.

Section 308.  Persons Deemed Owners.
              --------------------- 

     Prior to due presentment of a Security for registration of transfer, the
Company, the Trustee and any agent of the Company or the Trustee may treat the
Person in whose name such Security is registered as the owner of 

                                      -68-
<PAGE>
 
    
such Security for the purpose of receiving payment of principal of (and
premium, if any) and (subject to Section 307) interest on such Security and
for all other purposes whatsoever, whether or not such Security be overdue,
and neither the Company, the Trustee nor any agent of the Company or the
Trustee shall be affected by notice to the contrary.      

Section 309.  Cancellation.
              ------------ 
    
     All Securities surrendered for payment, redemption, registration of
transfer or exchange or for credit against any Offer to Purchase pursuant to
Section 1013 or 1015  shall, if surrendered to any Person other than the
Trustee, be delivered to the Trustee and shall be promptly cancelled by it.  The
Company may at any time deliver to the Trustee for cancellation any Securities
previously authenticated and delivered hereunder  that the Company may have
acquired in any manner whatsoever, and all Securities so delivered shall be
promptly cancelled by the Trustee.  No Securities shall be authenticated in lieu
of or in exchange for any Securities cancelled as provided in this Section 309,
except as expressly permitted by this Indenture.  All cancelled Securities held
by the Trustee shall be disposed of as directed by a Company Order; provided
                                                                    --------
that the Trustee shall not be required to destroy cancelled Securities.      

Section 310.  Computation of Interest.
              ----------------------- 

     Interest on the Securities shall be computed on the basis of a 360-day year
of twelve 30-day months.

Section 311.  CUSIP Numbers.
              ------------- 

     The Company in issuing the Securities may use "CUSIP" numbers (if then
generally in use), and, if so, the Trustee shall use CUSIP numbers in notices of
redemption or repurchase as a convenience to Holders; provided that any such
                                                      --------              
notice may state that no representation is made as to the correctness of such
numbers either as printed on the Securities or as contained in any notice of a
redemption or repurchase and that reliance may be placed only on the other
identification numbers printed on the Securities, and any such redemption or
repurchase 

                                      -69-
<PAGE>
 
shall not be affected by any defect in or omission of such numbers.

Company shall, upon demand of the Trustee, pay to it, for the benefit of the
Holders of such Securities, the whole amount then due and payable on such
Securities

enforceable, interest on any overdue Accreted Value or principal, as the case
may be, (premium, if any) and interest, and on any overdue interest, at the rate
provided by the Securities, and, in addition thereto, such further amount as
shall be sufficient to cover the costs and expenses of collection, including
the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel.     

     If the Company fails to pay such amounts forthwith upon such demand, the
Trustee, in its own name and as trustee of an express trust, may institute a
judicial proceeding for the collection of the sums so due and unpaid, may
prosecute such proceeding to judgment or final decree and may enforce the same
against the Company or any other obligor upon the Securities and collect the
moneys adjudged or decreed to be payable in the manner provided by law out of
the Property of the Company or any other obligor upon the Securities, wherever
situated.

     If an Event of Default occurs and is continuing, the Trustee may in its
discretion proceed to protect and enforce its rights and the rights of the
Holders by such appropriate judicial proceedings as the Trustee shall deem most
effectual to protect and enforce any such rights, whether for the specific
enforcement of any covenant or agreement in this Indenture or in aid of the
exercise of any power granted herein, or to enforce any other proper remedy.

overdue Accreted Value or principal, as the case may be, (premium, if any) or

or counsel) allowed in any such proceeding. In particular, the Trustee shall
be authorized to collect and receive any moneys or other property payable or
deliverable on any such claims and to distribute the same; and any custodian,
receiver, assignee, trustee, liquidator, sequestrator or other similar
official in any such judicial proceeding is hereby authorized by each Holder
to make such payments to the Trustee and, in the event that the Trustee shall
consent to the making of such payments directly to the Holders, to pay to the
Trustee any amount due it for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any
other amounts due the Trustee under Section 607 . To the extent that payment
of any such compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel, and any amounts due the Trustee under Section 607
hereof out of the estate in any such proceeding shall be denied for any
reason, payment of the same shall be secured by a Lien and shall be paid out
of any and all distributions, dividends, money, securities and other
properties that the Holders of the Securities may be entitled to receive in
such proceedings whether in liquidation or under any plan of reorganization or
arrangement or otherwise.

authorize or consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or composition affecting the Securities
or the rights of any Holder thereof or to authorize the Trustee to vote in
respect of the claim of any Holder in any such proceeding; provided that the

right in any manner whatever by virtue of, or by availing of, any provision of
this Indenture to affect, disturb or prejudice the rights of any other Holders,

Default arising therefrom shall be deemed to have been cured, for every

any such certificates or opinions that by any provision hereof are specifically
required to be furnished to the Trustee, the Trustee shall be under a duty to

Section 610.  Resignation and Removal; Appointment of  Successor.
              -------------------------------------------------- 
    
          (a)  No resignation or removal of the Trustee and no appointment of a
successor Trustee pursuant to this Article Six shall become effective until the
acceptance of appointment by the successor Trustee in accordance with the
applicable requirements of Section 611.      
     
          (b)  The Trustee may resign at any time by giving written notice
thereof to the Company.  If an instrument of acceptance by a successor Trustee
in accordance with the applicable requirements of Section 611  shall not have
been delivered to the Trustee within 30 days after the giving of such notice of

majority in principal amount of the Outstanding Securities, delivered to the
Trustee and to the Company.      

          (d)  If at any time:
    
               (1)  the Trustee shall fail to comply with Section 608 after
written request therefor by the Company or by any Holder who has been a bona
fide Holder of a Security for at least six months, or      
    
               (2)  the Trustee shall cease to be eligible under Section 609

Holder of a Security for at least six months may, on behalf of himself and all
others similarly situated, petition any court of competent jurisdiction for the
removal of the Trustee and the appointment of a successor Trustee.      
    
          (e)  If the Trustee shall resign, be removed or become incapable of
acting, or if a vacancy shall occur in the office of Trustee for any cause, the
Company, by a Board Resolution, shall promptly appoint a successor Trustee.  If,
within one year after such resignation, removal or incapability, or the
occurrence of such vacancy, a successor Trustee shall be appointed by Act of the
Holders of a majority in principal amount of the Outstanding Securities
delivered to the Company and the retiring Trustee, the successor Trustee so
appointed shall, forthwith upon its acceptance of such appointment in
accordance with the applicable requirements of Section 611, become the
successor Trustee and supersede the successor Trustee appointed by the
Company. If no successor Trustee shall have been so appointed by the Company
or the Holders and accepted appointment in accordance with the applicable
requirements of Section 611, any Holder who has been a bona fide Holder of a
Security for at least six months may, on behalf of himself and all others
similarly situated, petition any court of competent jurisdiction for the

<PAGE>
 
    
successor Trustee, without any further act, deed or conveyance, shall become
vested with all the rights, powers, trusts and duties of the retiring Trustee;
but, on request of the Company or the successor Trustee, such retiring Trustee
shall, upon payment of any amounts then due under Section 607, execute and
deliver an instrument transferring to such successor Trustee all the rights,
powers and trusts of the retiring Trustee and shall duly assign, transfer and
deliver to such successor Trustee all property and money held by such retiring

              ---------------------------------
              or Succession to Business.
              ------------------------- 

     Any corporation into which the Trustee may be merged or converted or with
which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all the corporate trust business
of the Trustee, shall be the successor of the Trustee hereunder, provided that
                                                                 --------     
such corporation shall be otherwise qualified and eligible under this Article
Six, without the execution or filing of any paper or any further act on the part
of any of the parties hereto.  In case any Securities shall have been
authenticated, but not delivered, by the Trustee then in office, any successor
by merger, conversion or consolidation to such authenticating Trustee may adopt
such authentication and deliver the Securities so authenticated with the same
effect as if such successor Trustee had itself authenticated such Securities.

Section 613.  Preferential Collection
              -----------------------
              of Claims Against Company.

     If and when the Trustee shall be or become a creditor of the Company (or
any other obligor upon the Securities), the Trustee shall be subject to the
provisions of the Trust Indenture Act regarding the collection of claims against
the Company (or any such other obligor).

Section 614.  Appointment of Authenticating Agent.
              ----------------------------------- 
    
     The Trustee may from time to time appoint an Authenticating Agent or Agents
that shall be authorized to act on behalf of the Trustee to authenticate
Securities issued upon original issue and upon exchange, registration of
transfer or partial redemption or partial purchase or pursuant to Section 306,
and Securities so authenticated shall be entitled to the benefits of this
Indenture and shall be valid and obligatory for all purposes as if
authenticated by the Trustee hereunder. Wherever reference is made in this
Indenture to the authentication and delivery of Securities by the Trustee or
the Trustee's certificate of authentication, such reference shall be deemed to
include authentication and delivery on behalf of the Trustee by an
Authenticating Agent and a certificate of authentication executed on behalf of
the Trustee by an Authenticating Agent. Each Authenticating Agent shall be
acceptable to the Company and shall at all times be a corporation organized
and doing business under the laws of the United States of America, any State
thereof or the District of Columbia, authorized under such laws to act as
Authenticating Agent, having a combined capital and surplus of not less than
$50,000,000 and subject to supervision or examination by Federal or State
authority. If such Authenticating Agent publishes reports of condition at
least annually, pursuant to law or to the requirements of said supervising or
examining authority, then for the purposes of this Section 614, the combined
capital and surplus of such Authenticating Agent shall be deemed to be its
combined capital and surplus as set forth in its most recent report of
condition so published. If at any time an Authenticating Agent shall cease to
be eligible in accordance with the provisions of this Section 614, such
Authenticating Agent shall resign immediately in the manner and with the
effect specified in this Section 614.      

                                      -92-
<PAGE>
 
    
     Any corporation into which an Authenticating Agent may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which such Authenticating Agent
shall be a party, or any corporation succeeding to the corporate agency or
corporate trust business of an Authenticating Agent, shall continue to be an
Authenticating Agent, provided such corporation shall be otherwise eligible
under this Section, without the execution or filing of any paper or any further
act on the part of the Trustee or the Authenticating Agent. In case any
Securities shall have been authenticated, but not delivered, by the
Authenticating Agent then in office, any successor by merger, conversion or
consolidation to such authenticating Authenticating Agent may adopt such
authentication and deliver the Securities so authenticated with the same
effect as if such successor Trustee had itself authenticated such Securities.
     
    
     An Authenticating Agent may resign at any time by giving written notice
thereof to the Trustee and to the Company.  The Trustee may at any time
terminate the agency of an Authenticating Agent by giving written notice thereof
to such Authenticating Agent and to the Company.  Upon receiving such a notice
of resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section 614, the Trustee may appoint a successor
Authenticating Agent that shall be acceptable to the Company and shall give
notice of such appointment in the manner provided in Section 106, to all Holders
as their names and addresses appear in the Security Register.  Any successor
Authenticating Agent upon acceptance of its appointment hereunder shall become
vested with all the rights, powers and duties of its predecessor hereunder, with
like effect as if originally named as an Authenticating Agent.  No successor
Authenticating Agent shall be appointed unless eligible under the provisions of
this Section 614.      

     The Company agrees to pay to each Authenticating Agent from time to time
reasonable compensation for its services under this Section.

Indenture cannot be modified or waived without the consent of the Holder of
each Outstanding Security affected thereby.      

         

          It shall not be necessary for any Act of Holders under this Section
902 to approve the particular form of any proposed supplemental indenture, but
it shall be sufficient if such Act shall approve the substance thereof.

          After a supplemental indenture under this Section becomes effective,
the Company shall mail to the Holders affected thereby a notice briefly
describing the supplemental indenture.  Any failure of the Company to mail such
notice, or any default therein, shall not, however, in any way impair or affect
the validity of any such supplemental indenture.

          In connection with any supplemental indenture or waiver under this
Article Nine, the Company may, but shall not be obligated to, offer to any
Holder who consents to such supplemental indenture, or to all Holders,

supplemental indenture permitted by this Article or the modifications thereby
of the trusts created by this Indenture, the Trustee shall be entitled to
receive, and (subject to Section 601) shall be fully protected in relying
upon, an Opinion of Counsel stating that the execution of such supplemental
indenture is authorized or permitted by this Indenture. The Trustee may, but

affects the Trustee's own rights, duties or immunities under this Indenture or
otherwise.

          Upon the execution of any supplemental indenture under this Article
Nine, this Indenture shall be modified in accordance therewith, and such
supplemental indenture shall form a part of this Indenture for all purposes; and
every Holder of Securities theretofore or thereafter authenticated and delivered
hereunder shall be bound thereby, unless it makes a change described in any of
clauses (1) through (6) of Section 902, in which case, the supplemental
indenture shall bind only each Holder of a Security who has consented to it and
every subsequent Holder of a Security or portion of a Security that evidences
the same Debt as the consenting Holder's Security; provided that any such waiver
                                                   --------

principal and premium of and interest on a Security, on or after the respective
dates set for such amounts to become due and payable, or to bring suit for the
enforcement of any such payment on or after such respective dates.      

Section 905.  Conformity with Trust Indenture Act.

Section 906.  Reference in Securities to Supplemental  Indentures.
              --------------------------------------------------- 

          Securities authenticated and delivered after the execution of any
supplemental indenture pursuant to this Article Nine may, and shall if
required by the Trustee, bear a notation in form approved by the Trustee as to
any matter provided for in such supplemental indenture. If the Company shall
so determine, new Securities so modified as to conform, in the opinion of the
Trustee and the Company, to any such supplemental indenture may be prepared
and executed by the Company and authenticated and delivered by the Trustee in
exchange for Outstanding Securities. Any failure to make the appropriate
notation on a new Security shall not affect the validity of such Security.

               ------------------------------- 

          The Company shall maintain in the Borough of Manhattan, The City of
New York, an office or agency where Securities may be presented or surrendered
for payment, where Securities may be surrendered for registration of transfer or
exchange and where notices and demands to or upon the Company in respect of the
Securities and this Indenture may be served.  The Company shall give prompt
written notice to the Trustee of the location, and any change in the location,
of such office or agency.  If at any time the Company shall fail to maintain any
such required office or agency or shall fail to furnish the Trustee with the
address thereof, such presentations, surrenders, notices and demands may be made
or served at the Corporate Trust Office of the Trustee, and the Company hereby
appoints the Trustee as its agent to receive all such presentations,
surrenders, notices and demands. In the event any such notice or demands are
so made or served on the Trustee, the Trustee shall promptly forward copies
thereof to the Company.

          The Company may also from time to time designate one or more other
offices or agencies (in or outside the Borough of Manhattan, The City of New
York) where the Securities may be presented or surrendered for any or all such
purposes and may from time to time rescind such  designations; provided that no

such designation or rescission shall in any manner relieve the Company of its

of New York, for such purposes.  The Company shall give prompt written notice to
the Trustee of any such designation or rescission and of any 

                                     -103-

change in the location of any such other office or agency. The Company hereby
initially designates the Corporate Trust Office of the Trustee as such office
of the Company.

Section 1003.  Money for Security Payments to be Held in Trust.
               ----------------------------------------------- 

          If the Company shall at any time act as its own Paying Agent, it
shall, on or before each due date of the principal of (and premium, if any) or
interest on any of the Securities, segregate and hold in trust for the benefit
of the Persons entitled thereto a sum sufficient to pay the principal (and
premium, if any) or interest so becoming due until such sums shall be paid to
such Persons or otherwise disposed of as herein provided and shall promptly
notify the Trustee of its action or failure so to act.

          Whenever the Company shall have one or more Paying Agents, it shall,
prior to each due date of the principal of (and premium, if any) or interest on
any Securities, deposit with a Paying Agent a sum sufficient to pay the
principal (and premium, if any) or interest so becoming due, such sum to be held
as provided by the Trust Indenture Act, and (unless such Paying Agent is the
Trustee) the Company shall promptly notify the Trustee of its action or failure
so to act.

          The Company shall cause each Paying Agent other than the Trustee to
execute and deliver to the Trustee an instrument in which such Paying Agent
shall agree with the Trustee, subject to the provisions of this Section 1003,
that such Paying Agent shall (i) comply with the provisions of the Trust
Indenture Act applicable to it as Paying Agent, (ii) give the Trustee notice of
any default by the Company (or other obligor upon the Securities) in the making
of any payment of principal of (and premium, if any) or interest in respect of
the Securities and (iii) during the continuance of any default by the Company
(or any other obligor upon the Securities) in the making of any payment in
respect of the Securities, upon the written request of the Trustee, forthwith
pay to the Trustee all sums held in trust by such Paying Agent as such.

          The Company may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, pay, or
by Company Order direct any Paying Agent to pay, to the Trustee all sums held in
trust by the Company or such Paying Agent, such sums to be held by the Trustee
upon the same trusts as those upon which such sums were held by the Company or
such Paying Agent; and, upon such payment by any Paying Agent to the Trustee,
such Paying Agent shall be released from all further liability with respect to
such money.
    
          Any money deposited with the Trustee or any Paying Agent, or then held
by the Company, in trust for the payment of the principal of (and premium, if
any) or interest on any Security and remaining unclaimed for two years after
such principal (and premium, if any) or interest has become due and payable
shall be paid to the Company on Company Request, or (if then held by the
Company) shall be discharged from such trust; and the Holder of such Security
shall thereafter, as an unsecured general creditor, look only to the Company for
payment thereof, and all liability of the Trustee or such Paying Agent with
respect to such trust money shall thereupon cease; provided that the Trustee or
                                                    --------                    
such Paying Agent, before being required to make any such repayment, may at
the expense of the Company cause to be published once, in a newspaper

and of general circulation in The City of New York, or mail to such Holder, or
both, notice that such money remains unclaimed and that, after a date
specified therein, which shall not be less than 30 days from the date of such
publication, any unclaimed balance of such money then remaining shall be
repaid to the Company.

that the Company shall not be required to preserve any such right or franchise
if the Board of Directors in good faith shall determine that the preservation
thereof is no longer desirable in the conduct of the

business of the Company and that the loss thereof is not disadvantageous in

made all necessary repairs, renewals, replacements, betterments and improvements
thereof, all as in the judgment of the Company may be necessary so that the
business carried on in connection therewith may be properly and advantageously
conducted at all times; provided that nothing in this Section 1005 shall prevent
                        --------                                                
the Company from discontinuing the operation or maintenance of any of such
material or properties or, subject to the provisions of Section 1015, disposing
of any of them if such discontinuance or disposal is, as determined by the Board
of Directors in good faith, desirable in the conduct of its business or the
business of any Restricted Subsidiary and not disadvantageous in any material
respect to the Holders, provided that the Restricted Subsidiaries and the
                        --------
Eligible Joint Ventures of the Company shall not be required to comply with the
foregoing provisions of this Section 1005 if they are prevented or restricted in
doing so by the terms of any loan or financing agreement, any charter document
or any other agreement or instrument.      

Section 1006.  Payment of Taxes and Other Claims.

governmental charges levied or imposed upon the Company or any of its Restricted
Subsidiaries or upon the income, profits or property of the Company or any of
its Restricted Subsidiaries, and (2) all lawful claims for labor, materials and
supplies that, if unpaid, might by law become a Lien upon the property of the

amounts adequate reserves have been  accrued to the extent required by GAAP.

Section 1007.  Maintenance of Insurance.
               ------------------------ 

    
          The Company shall, and shall cause its Restricted Subsidiaries and the
Eligible Joint Ventures to, keep at all times all of their Properties that are
of an insurable nature insured against loss or damage with insurers believed by
the Company to be responsible to the extent that Property of similar character
is usually so insured by Persons similarly situated and owning like Properties
in accordance with good business practice.  The Company shall, and shall cause
its Restricted Subsidiaries and the Eligible Joint Ventures to, use the proceeds
from any such insurance policy to repair, replace or otherwise restore all
material Properties to which such proceeds relate, provided that the Company

shall not be required to repair, replace or otherwise restore any such material
Property if the Board of Directors in good faith determines that such inaction
is desirable in the conduct of the business of the Company or any Restricted
Subsidiary and not disadvantageous in any material respect to the Holders, and
provided further that the Restricted Subsidiaries and the Eligible Joint
- -------- -------
Ventures of the Company shall not be required to apply insurance proceeds to
repair, replace or restore any material Property if they are prevented or
restricted in doing so by the terms of any loan or financing agreement, any
charter document or any other agreement or instrument.      

          The Company may adopt such other plan or method of protection, in lieu
of or supplemental to insurance with insurers, whether by the establishment of
an insurance fund or reserve to be held and applied to make good losses from
casualties, or otherwise, conforming to the system of self-insurance maintained
by corporations similarly situated and owning like Properties and not
disadvantageous to the Holders in any material respect, as may be determined by
the Board of Directors in good faith.

to be an Incurrence of Debt that is subject to the provisions of this Section
1008 other than this clause (ii), (iii) Debt in an aggregate principal amount

Company, its Restricted Subsidiaries and Eligible Joint Ventures in such Person
shall be Investments that shall be subject to the foregoing paragraph unless and

the designation of a Restricted Subsidiary as an Unrestricted Subsidiary, in
the manner provided in the definition of "Unrestricted Subsidiary," shall be
an Investment that shall be subject to the foregoing paragraph and (ii) the
transfer of the Company's interest (or portion thereof) in an entity that has
been deemed to be an Eligible Joint Venture directly or indirectly to an
Unrestricted Subsidiary shall be an Investment (to the extent of the interest
transferred) that shall be subject to the foregoing paragraph.

the case may be, after the Change of Control Purchase Date (assuming
sufficient moneys for the purchase thereof are deposited with the Trustee),
(6) that Holders electing to have a Security purchased pursuant to a Change of
Control Offer shall be required to surrender the Security, with the form
entitled "Option of Holder To Elect Purchase" on the reverse of the Security
completed, to the paying agent at the address specified in the notice prior to
the close of business on the fifth Business Day prior to the Change of Control
Purchase Date, (7) that a Holder shall 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 Change of Control Purchase Date, a telegram,
telex, facsimile transmission or letter setting forth the name of the Holder,
the principal amount of Securities the Holder delivered for purchase, and a
statement that such Holder is withdrawing his election to have such Securities
purchased and (8) that Holders that elect to have their Securities purchased
only in part shall be issued new Securities having a principal amount equal to
the portion of the Securities that were surrendered but not tendered and
purchased.

for payment all Securities or portions thereof tendered pursuant to the Change

prohibition is in effect.      
    
          The Company shall 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.

restrictive, taken as a whole, on the ability of the applicable Restricted

applicable jurisdiction, (iv) in connection with the execution and delivery
of an electric power or thermal energy purchase contract, or other contract

is a party and where such Restricted Subsidiary or such Eligible Joint Venture
is engaged, directly or indirectly, in the development, design, engineering,

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

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

(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

Section 1015.  Limitation on Dispositions.     
               --------------------------- 
    
          (a)  Subject to the provisions of Article Eight, the Company shall
not make and shall 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 sen-     

                                     -119-

tence of Section 1022, 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 or of any of its Restricted Subsidiaries or any Eligible Joint Venture
(or as otherwise required under the terms of such Debt), provided that, no
                                                         --------
such payment of Debt (x) under Permitted Working Capital Facilities or any
other revolving credit agreement shall count for this purpose unless the
related loan commitment, standby facility or the like shall be permanently
reduced by an amount equal to the principal amount so repaid and (y) owed to
the Company, a Restricted Subsidiary thereof or an Eligible Joint Venture
shall count for this purpose, 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 shall
constitute "Excess Proceeds."  Excess Proceeds shall be applied, as described
below, to make an offer (an "Excess Proceeds Offer") to purchase Securities at a
purchase price equal to 100% of Accreted Value thereof, plus accrued interest,
if any, to the date of purchase.     
    
          (b)  Notwithstanding the provisions of Section 1015(a), 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     

                                     -120-

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 shall be subject to
Section 1010.  Notwithstanding anything in the foregoing to the contrary, the
Company may not, and shall 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  three geothermal facilities located together at
the Naval Weapons Center at China Lake, California, sometimes referred to as the
"Coso Project," other than for consideration consisting solely of cash.     
    
          (c)  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 shall not be required to be applied at the time
provided above but may be retained 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 shall 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 shall be
effected immediately and the repatriated Net Cash Proceeds shall be applied in
the manner set forth in this Section 1015(c) as if such Asset Disposition had
occurred on the     

                                     -121-
<PAGE>
 
    
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
this Section 1015(a), the Company may apply such Net Cash Proceeds pursuant
to such provision.     
    
          (d)  If the  Securities tendered pursuant to an Excess Proceeds Offer
have an aggregate purchase price that is less than the Excess Proceeds available
for the purchase of the Securities, the Company may use the remaining Excess
Proceeds for general corporate purposes without regard to the provisions of
this Section 1015(d).  The Company shall not be required to make an Excess
Proceeds Offer pursuant to this Section 1015 if the Excess Proceeds available
therefor are less than $10 million, provided that the lesser amounts of such
                                    --------                                
Excess Proceeds shall be carried forward and cumulated for each
36 consecutive month period for purposes of determining whether an Excess
Proceeds 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 shall not reduce the amount of cumulated Excess
          --------                                                              
Proceeds or relieve the Company of its obligation hereunder to make an Excess

comply with and shall have no liability in respect of any term, condition or
limitation set forth in any such specified Section (to the extent so specified
in the case of Sections 501(1) and 501(4)), whether directly or indirectly by
reason of any reference elsewhere herein to any such Section or by reason of any
reference in any such Section to any other provision herein or in any other
document; but the remainder of this Indenture and such Securities shall be
unaffected thereby.

days following the deposit, the trust fund shall 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
manner were properly briefed, a court should hold that the deposit of moneys

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.     
    
          (3)  In the event of an election to have Section 1203 apply to the

paid or redeemed such Securities on the applicable dates, (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 shall 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 manner were
properly briefed, a court should hold that the deposit of moneys and/or U.S.
Government Obligations as provided in Section 1204(1) 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.

Section 1204(2)(C)(y) or 1204(3)(iii)(y)) during the period ending on the 123rd
day after the date of such deposit.     

          (5)  Such Defeasance or Covenant Defeasance shall not cause the
Trustee to have a conflicting interest within the meaning of the Trust Indenture
Act (assuming all Securities are in default within the meaning of such Act).

          (6)  Such Defeasance or Covenant Defeasance shall 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 it is bound.

          (7)  Such Defeasance or Covenant Defeasance shall not result in the
trust arising from such deposit constituting an investment company within the
meaning of the Investment Company Act of 1940, as amended, unless such trust
shall be registered under such Act or exempt from registration thereunder.

          (8)  The Company shall have delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, each stating that all conditions
precedent with respect to such Defeasance or Covenant Defeasance have been
complied with.
    
          (9)  If the Securities are listed on a national securities exchange,
the Company shall have delivered to the Trustee an Opinion of Counsel to the
effect that the Securities shall not be delisted as a result of such deposit,
defeasance and discharge.

          Subject to the provisions of the last paragraph of Section 1003,
all money and U.S. Government Obligations (including the proceeds thereof)
deposited with the Trustee or other qualifying trustee (solely for purposes of
this Section 1205 and Section 1206, the Trustee and any such other trustee are
referred to collectively as the "Trustee") pursuant to Section 1204 or
otherwise in respect of the Outstanding Securities shall be held in trust and
applied by the Trustee, in accordance with the provisions of such Securities
and this Indenture, to the payment, either directly or through any such Paying
Agent (other than the Company acting as its own Paying Agent) as the Trustee
may determine, to the Holders of such Securities, of all sums due and to
become due thereon in respect of principal and any premium and interest, but
money so held in trust need not be segregated from other funds except to the
extent required by law.    
    
          The Company shall pay and indemnify the Trustee against any tax, fee
or other charge imposed on or assessed against the U.S. Government Obligations
deposited pursuant to Section 1204  or the principal and interest received in
respect thereof other than any such tax, fee or other charge  that by law is for
the account of the Holders of Outstanding Securities.     
    
          Anything in this Article Twelve to the contrary notwithstanding, the
Trustee shall deliver or pay to the Company from time to time upon Company
Request any money or U.S. Government Obligations held by it as provided in
Section 1204 that, in the opinion of a nationally recognized firm of
independent public accountants expressed in a written certification thereof
delivered to the Trustee, are in excess of the amount thereof that would then
be required to be deposited to effect the Defeasance or Covenant Defeasance, as
the case may be, with respect to the Outstanding Securities.     

Section 1206.  Reinstatement.
               -------------

accordance with this Article Twelve with respect to any Securities by reason
of any order or judgment of any court or governmental authority enjoining,
restraining or otherwise prohibiting such applica-

tion, then the obligations under this Indenture and such Securities from which
the Company has been discharged or released pursuant to Section 1202 or 1203
shall be revived and reinstated as though no deposit had occurred pursuant to
this Article Twelve with respect to such Securities, until such time as the
Trustee or Paying Agent is permitted to apply all money held in trust pursuant
to Section 1205 with respect to such Securities in accordance with this
Article Twelve; provided that if the Company makes any payment of principal
                --------                    
of or any premium or interest on any such Security following such
reinstatement of its obligations, the Company shall be subrogated to the
rights (if any) of the Holders of such Securities to receive such payment from
the money so held in trust.

Ladies and Gentlemen:
   
We have acted as counsel to California Energy Company, Inc. (the "Company"), a

terms of an underwriting agreement to be executed by the Company and Lehman
Brothers Inc., Salomon Brothers Inc, Donaldson, Lufkin & Jenrette Securities
Corporation and Bear, Stearns & Co. Inc. (the "Underwriters").     
   
We have examined copies of the Certificate of Incorporation and By-Laws of the
Company, and the amendments thereto, the Registration Statement, all
resolutions adopted by the Company's Board of Directors and other records and
documents that we have deemed necessary for the purpose of this opinion. We
have also examined such other documents, papers, statutes and authorities as we

In our examination, we have assumed the genuineness of all signatures and the
conformity to original documents of all copies submitted to us. As to various
questions of fact material to our opinions, we have relied on statements and
certificates of officers and representatives of the Company and public
officials.     
   
Based upon and subject to the foregoing, we are of the opinion that:     
 
  1. The Notes have been duly authorized by all necessary corporate action of
     the Company, and when duly executed, authenticated and delivered by or
     on behalf of the Company and paid for by the Underwriters, will be valid
     and binding obligations of the Company and will be entitled to the
     benefits of the Indenture; and
 
  2. The Indenture, when duly executed and delivered by the Company and the
     Trustee, will constitute a valid and binding instrument of the Company.

Salomon Brothers Inc, Donaldson, Lufkin & Jenrette Securities Corporation and
Bear, Stearns & Co. Inc. (the "Underwriters"). We have been asked to provide an
opinion concerning the anticipated material United States federal income tax
consequences of the purchase, ownership and disposition of the Notes in support
of the discussion that appears under the caption "Certain Federal Income Tax
Considerations" in the Registration Statement (the "Tax Discussion").     
   
We have examined copies of the Certificate of Incorporation and By-Laws of the
Company, and the amendments thereto, the Registration Statement, all
resolutions adopted by the Company's Board of Directors and other records and
documents that we have deemed necessary for the purpose of this opinion. We
have also examined such other documents, papers, statutes and authorities as we

Based on the foregoing, we are of the opinion that the anticipated material
United States federal income tax consequences of the purchase, ownership and
disposition of the Notes should be as described in the Tax Discussion, and we
hereby incorporate such discussion as if it were set forth in full herein.
