                    Interest Payable January 15 and July 15
 
                           -------------------------

  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 semiannual 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
amount thereof plus accrued and unpaid interest, if any.  See "Description of
the Notes--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 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% shareholder (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 these 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 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 power sales contract.  Pursuant to a
memorandum of understanding, the Company has commenced early stage site work on
a proposed 30 MW geothermal project in Newberry, Oregon, 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,
 

                                       4
<PAGE>
 
the Company has diversified into other environmentally responsible sources of
power generation.  The Company is currently constructing a 50 MW gas fired
facility in Yuma, Arizona (the "Yuma Project") to sell electricity to San Diego
Gas & Electric Company (SDG&E") under a 30-year power sales contract, which
project is expected to be completed by mid-year 1994.  The Company expects
future diversification through the selected 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 the 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 and finance international 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 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 "Business--International Projects and Development
Opportunities."

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 the construction loan agreement
for the Upper Mahiao Project will be executed in March 1994 and that the notice
to proceed will be issued promptly thereafter under the construction contract,
which was itself 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 contribution to the 

                                       5
<PAGE>
 
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 and (iv) for general corporate
purposes.  As project loans are repaid, the Company may use the proceeds again
for any of such permitted uses.  See "Use of Proceeds."

Ranking............... The Notes will be senior unsecured obligations of the
                       Company ranking pari passu in right of payment of
                       principal and interest with all other existing and future
                       senior unsecured obligations of the Company.  The Company
                       is a holding company that derives substantially all of
                       its income from its operating subsidiaries and joint
                       venture projects.  Accordingly, the Notes will
                       effectively be subordinated to debt at the project or
                       subsidiary level.  The Notes will rank senior to all
                       other existing and future subordinated indebtedness of
                       the Company.

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..... The Indenture governing the Notes contains certain
                       covenants which, among other things, will restrict the
                       ability of the Company, its Restricted Subsidiaries and
                       its Eligible Joint Ventures to incur additional Debt
                       (other than Non-Recourse Debt (as defined)), to pay
                       dividends and make certain other Restricted Payments, to
                       encumber or sell assets, to enter into transactions with
                       Affiliates, to enter into new lines of business, to make
                       certain investments, to merge or consolidate with any
                       other person or to transfer or lease assets.  These
                       covenants are described in detail below under the caption
                       "Description of the Notes--Certain Covenants."

                       on the Notes which continues for a period of 30 days,
                       (ii) default in the payment of principal, or premium, if
                       any, when due, including pursuant to a required
                       repurchase, (iii) the failure by the Company to perform
                       any covenant contained in the Indenture, which breach
                       continues for 30 days after receipt of notice thereof,
                       (iv) the failure of the Company or any Significant
                       Subsidiary to pay when due beyond any applicable grace
                       period, or the acceleration of, Debt (other than Non-
                       Recourse Debt of Significant Subsidiaries) in excess of
                       $25 million, and (v) the occurrence of certain events of
                       bankruptcy, insolvency or reorganization.

(1) 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."
(6) The "Consolidated EBITDA" and "Consolidated Fixed Charges" is calculated in
    accordance with the respective definitions of such terms in the Indenture
    and set forth herein under "Description of Senior 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 Senior 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 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 expenses payable by the
    Company estimated at $250,000.  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 senior notes
    outstanding.

                           INVESTMENT CONSIDERATIONS

  In addition to the other information contained in this Prospectus and the
documents incorporated herein by reference, prospective investors should
consider the factors set forth below prior to deciding whether to invest in the
Notes offered hereby.

Development Uncertainty

  The Company is actively seeking to develop, construct, own and operate new
power projects utilizing geothermal and other technologies, both domestically
and internationally, the completion of any of which is subject to substantial
risk.  Development can require the Company to expend significant sums for
preliminary engineering, permitting, legal and other expenses in preparation for
competitive bids which the Company may not win or before it can be determined
whether a project is feasible, economically attractive or capable of being
financed.  Successful development is contingent upon, among other things,
negotiation of construction, fuel supply and power sales contracts with other
project participants on terms satisfactory to the Company, and receipt of
required governmental permits and consents.  Further, there can be no assurance
that the Company will obtain access to the substantial debt and equity capital
required to develop and construct electric power projects or to refinance
projects for which the Company has provided initial construction financing from
the proceeds of the Notes.  See "Business--International Projects and
Development Opportunities--Funding for International Projects."  The Company's
future growth is dependent, in large part, upon the demand for significant
amounts of additional electrical generating capacity and the Company's ability
to obtain contracts to supply portions of this capacity.  There can be no
assurance that development efforts on any particular project, or the Company's
efforts generally, will be successful.  See "Business--The Independent Power
Production Market."

Development Uncertainty Outside the United States

  The Company believes that the international independent power market holds the
majority of new opportunities for financially attractive private power
development in the next several years.  The financing and development of
projects outside the United States entails significant political and financial
risks (including, without limitation, uncertainties associated with first time
privatization efforts in the countries involved, currency exchange rate
fluctuations, currency repatriation restrictions, political instability, civil
unrest and expropriation) and other structuring issues that have the potential
to cause substantial delays or material impairment of value to the project being
developed which the Company may not be fully capable of insuring against.  The
uncertainty of the legal environment in certain foreign countries in which the
Company may develop or acquire projects could make it more difficult for the
Company to enforce its rights under agreements relating to such projects.  In
addition, the laws and regulations of certain countries may limit the ability of
the Company to hold a majority interest in some of the projects that it may
develop or acquire.  The Company's international projects may, in certain cases,
be terminated by the government.  See "Business--The Independent Power
Production Market" and  "--International Projects and Development
Opportunities."

Holding Company Structure; Notes are Unsecured Obligations

  The Company is a holding company which derives substantially all of its
operating income from its subsidiaries' ownership interests in the Coso Joint
Ventures 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
 

                                       11

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 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--
Domestic Projects and Development Opportunities --The Coso Project--Non-
Recourse Coso Project Refinancing."

High Leverage; Additional Debt Permitted at Subsidiary or Project Level;
Priority of Project Debt

  After giving effect to the Offering, the Company will be highly leveraged.  As
of December 31, 1993, the Company's total consolidated indebtedness was $382.6
million (excluding deferred income and redeemable preferred stock), its total
consolidated assets were $716.0 million and its stockholders' equity was $211.5
million.  At such date, on a pro forma basis, after giving effect to the
completion of this Offering and the Company's planned defeasance of its senior
notes, the Company's total consolidated indebtedness (excluding deferred income
and redeemable preferred stock) would have been $746.9 million, its total
consolidated assets would have been $1,077.0 million and its stockholders'
equity would have been $208.2 million.  See "Capitalization" and "Selected
Historical Consolidated Financial and Operating Data."

  The Indenture does not limit the amount of non-recourse indebtedness which may
be incurred 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 the 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--Domestic
Projects and Development Opportunities--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 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 owned by the Coso Joint Ventures
(which facilities are sometimes referred to as the "Navy I Project," the "BLM
Project" and the "Navy II Project") 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% 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--Domestic
Projects and Development Opportunities--The Coso Project--Certain Material
Contracts" and "--Non-Recourse Coso Project Financing."
 

                                       13
<PAGE>
 
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 CPUC), 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--Domestic Projects and
Development Opportunities--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--Domestic Projects and
Development Opportunities--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.  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--Domestic Projects and Development Opportunities--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."
 

                                       14
<PAGE>
 
Many of the Company's competitors have more extensive and more diversified
developmental or operating experience (including international experience) and
greater financial resources than the Company.  In the domestic market, the
Energy Policy Act of 1992 is expected to increase competition.

Original Issue Discount; Effect on the Holders of the Notes and the Company

  The Notes will be issued at a substantial discount from their principal amount
at maturity.  Consequently, purchasers of the Notes should be aware that,
although cash interest will not accrue on the Notes prior to January 15, 1997,
and there will be no periodic payments of cash interest on the Notes prior to
July 15, 1997, original issue discount (that is, the difference between the
stated redemption price at maturity and the issue price of the Notes) will
accrue from the issue date of the Notes and will be includable as interest
income periodically (including for periods ending prior to January 15, 1997) in
a Holder's gross income for U.S. federal income tax purposes in advance of
receipt of the cash payments to which the income is attributable.  See "Certain
Federal Income Tax Considerations" for a more detailed discussion of the federal
income tax consequences to the Holders regarding the purchase, ownership and
disposition of the Notes.  Further, the Notes may be subject to the high yield
discount obligation rules, in which case the Company would not be able to deduct
the original issue discount attributable to the Notes until paid in cash or
property.  As explained in, and subject to, the discussion under "Certain
Federal Income Tax Considerations--Certain Federal Income Tax Considerations to
the Company and to Corporate Holders," the Notes will be subject to these rules
if their yield to maturity equals or exceeds a Treasury-based interest rate in
effect for the month of their issuance plus five percentage points.  For long-
term debt instruments with an average life of ______ issued on _______ __, 1994,
such Treasury-based interest rate plus five percentage points is _____%
compounded semiannually.  If these high yield discount rules apply, the
Company's after tax cash flow may be less than if such original issue discount
were deductible when accrued.  In addition, if a bankruptcy case were to be
commenced by or against the Company under the U.S. Bankruptcy Code after the
issuance of the Notes, the claim of a Holder with respect to the principal
amount thereof may be limited to an amount equal to the sum of (i) the initial
offering price and (ii) that portion of the original issue discount that is not
deemed to constitute "unmatured interest" for purposes of the U.S. Bankruptcy
Code.  Any original issue discount that was not amortized as of any such
bankruptcy filing would constitute "unmatured interest."

No Prior Public Market; Possible Volatility Of Note Price

  Prior to the Offering, there has been no public market for the Notes.  The
Company intends to make application to the New York Stock Exchange to have the
Notes listed for trading thereon, but there can be no assurance that 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 $34
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--Definitions."

      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 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) The "Consolidated EBITDA" and "Consolidated Fixed Charges" is calculated
      with respect to the respective definitions of such terms in the
      Indenture and set forth herein under "Description of Senior 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 Senior 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 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% 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 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 by 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 Coso Project's average electricity prices per kWh in 1993, 1992 and
1991 were comprised of (in cents):

  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* were 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 MPE settlement, 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
variable rate debt on the Coso Project was refinanced in 1992 with 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 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 O&M and capital costs and semiannually to each
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 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.
 

                                       25
<PAGE>
 
  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.

  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 of 1993, the Company issued $100.0 million 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 each year, commencing
on July 31, 1993. The 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 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., a thirty person engineering firm for a

                                       26
<PAGE>
 
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
aggregate. 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 statement). In
addition, in 1991 the Company issued one thousand shares of its Series C
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, 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
 

                                       27
<PAGE>
 
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 Activities."

  In addition to the 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 of 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
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 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%
shareholder (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.

  Three of these 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.

  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 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 power sales contract. Pursuant to a
memorandum of understanding, the Company has commenced early stage site work on
a proposed 30 MW geothermal project in Newberry, Oregon, 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 gas fired facility in Yuma, Arizona (the "Yuma
Project") to sell electricity to San Diego Gas & Electric Company (SDG&E") under
a 30-year power sales contract, which project is expected to be completed by 
mid-year 1994. The Company expects future diversification through
 

                                       29
<PAGE>
 
  the selected 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 the 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 and finance international 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 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 Projects
  and Development Opportunities."

       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 the construction loan agreement
  for the Upper Mahiao Project will be executed in March 1994 and that the
  notice to proceed will be issued promptly thereafter under the construction
  contract, which was itself 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 contribution 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

                                       30
<PAGE>
 
  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 Power 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.]


       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.

                Domestic Projects and Development Opportunities

  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 (sometime the "Navy I
  Project," the BLM Project" and the "Navy II project" and sometimes the "Navy I
  Plant," the "BLM Plant" and the "Navy II Plant") is owned by a separate
  partnership (the "Navy I Joint Venture," the "BLM Joint Venture" and the "Navy
  II Joint Venture," or, collectively, the "Coso Joint Ventures").  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

                                       32
<PAGE>
 
  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.

       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
  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

                                       33
<PAGE>
 
  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 S04 Agreements for 1993 for the Navy I Plant,
  BLM Plant and Navy II Plant were approximately 12.0 cents/kWh.  For the period
  of January 10, 1994 through February 13, 1994, SCE's Avoided Cost was 2.9
  cents/kWh (weighted average of mid-peak, off-peak and super off-peak).
  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 S04 Agreement for the Navy I Plant specifies
  a contract

                                       34
<PAGE>
 
  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.

       Financial and Operating Performance

       Set forth below are the average operating capacity factor and total sales
  revenues of each Coso Project facility for the years ended December 31, 1991,
  1992 and 1993.

       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, $47,916,000 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 Coso Notes Indenture, (ii) certain financial ratios
  must be met, and (iii) certain thresholds must be met regarding the
  availability of adequate geothermal resource

                                       36
<PAGE>
 
  for each Plant and for the 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 a
  limited partnership interest in Caithness CEA Geothermal L.P.  ("CCG"), a
  partnership which is, in turn, a limited partner in Caithness Coso Holdings,
  L.P., the Caithness Partnership which is a partner in the BLM Project.  In
  addition, certain cash flows of four Caithness affiliates have been pledged to
  CEGC-Mojave which relate in part to cash received as a result of distributions
  from the Navy I, BLM and Navy II Projects.  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, including all of the cash flows related to the interest in
  CCG, 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 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 $19,097,000 in principal amount of notes due to the
  Company 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

                                       37
<PAGE>
 
  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 generating facility 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/kWh, comprising an
  energy payment of 1.8 cents/kWh (which is adjustable pursuant to an inflation-
  based index) and a capacity payment of 4.5 cents/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 power 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

                                       38
<PAGE>
 
  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 late 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 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.
  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

                                       39
<PAGE>
 
  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 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 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.  In
  pursuing international projects, the Company intends to maintain a significant
  equity ownership position 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

                                       40
<PAGE>
 
  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 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

                                       41
<PAGE>
 
  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% 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 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, that each of the Company and Kiewit will provide 50% of the equity
  required for financing a project developed by the joint venture and that 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

                                       42

  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.

                                       43
<PAGE>
 
  Until 1987, NAPOCOR had a monopoly on power generation and transmission in the
  Philippines.  In 1987, then President Aquino issued 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.

  Upper Mahiao Project

       The Company is negotiating the final terms of the construction and term
  project financing for a 120 MW geothermal project to be located in the Greater
  Tongonan area of the island of Leyte, Republic of the Philippines (the "Upper
  Mahiao Project").  The Upper Mahiao Project will be built, owned and operated
  by CE Cebu Geothermal Power Company, Inc. ("CE Cebu"), a Philippine
  corporation that will be more than 95% indirectly owned by the Company.  It
  will sell 100% of its capacity on a "take-or-pay" basis (described below) to
  PNOC-EDC, which will in turn sell the power to NAPOCOR for distribution to the
  island of Cebu, located about 40 miles west of Leyte.

       The Company estimates that Upper Mahiao will have a total project cost of
  approximately $226 million, including interest during construction, project
  contingency costs and a debt service reserve fund.  A consortium of
  international banks is expected to provide an approximately $170 million
  project-financed, nonrecourse construction loan, supported by political risk
  insurance from ExIm Bank.  The Company expects that the term loan for the
  project will also be provided by ExIm

                                       44
<PAGE>
 
  Bank, and that both the construction and the term loan agreements will be
  executed in March 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
  "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 EPC Contract
  provides liquidated damage protection of 30% of the EPC Contract price.
  Ormat's performance under the EPC Contract will be backed by a completion
  guaranty of Ormat, by letters of credit, and by a guaranty of Ormat
  Industries, Ltd., an Israeli corporation and the parent of Ormat, in each case
  for the benefit of, and satisfactory to, the Project lenders.

       Under the terms of the Energy Conversion Agreement, executed on September
  6, 1993 (the "Upper Mahiao ECA"), CE Cebu will build, own and operate the
  Project during the two-year construction period and the ten-year cooperation
  period, after which ownership will be transferred to PNOC-EDC at no cost.  The
  effectiveness of the Upper Mahiao ECA is subject to the satisfaction or waiver
  of certain conditions prior to March 8, 1994 (subject to extension by
  agreement of the parties which is anticipated by the Company to be readily
  available through April 1, 1994) including finalization of the principal
  project documents (including, a power purchase agreement between PNOC-EDC and
  NAPOCOR), posting by Ormat of a construction performance bond in favor of
  PNOC-EDC in the amount of approximately $11.8 million, obtaining permits and
  approvals from various Philippine governmental authorities and arranging
  financing commitments.  In the event the parties are unable to satisfy such
  conditions before the agreed upon effectivity date, either party may terminate
  the Upper Mahiao ECA and such party shall reimburse the other party for its
  costs and expenses incurred in connection with such agreement.

       The Project will be located on land to be provided by PNOC-EDC at no
  cost; it will take geothermal steam and fluid, also provided by PNOC-EDC at no
  cost, and convert its thermal energy into electrical energy to be sold to
  PNOC-EDC on a "take-or-pay" basis.  Specifically, PNOC-EDC will be obligated
  to pay for the electric capacity that is nominated each year by CE Cebu,
  irrespective of whether PNOC-EDC is willing or able to accept delivery of such
  capacity.  PNOC-EDC will pay to CE Cebu a fee (the "Capacity Fee") based on
  the plant capacity nominated to PNOC-EDC in any year (which, at the plant's
  design capacity is approximately 95% of total contract revenues) and a fee
  (the "Energy Fee") based on the electricity actually delivered to PNOC-EDC
  (approximately 5% of total contract revenues).  The Capacity Fee consists of
  three 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.

                                       45
<PAGE>
 
  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 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 Project

       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 10% by another industrial company. It will sell 100% of
  its capacity on a take-or-pay basis (as described above for the Upper Mahiao
  Project) to PNOC-EDC, which will in turn sell the power to NAPOCOR for
  distribution to the island of Luzon.

       The Company estimates that Mahanagdong will have a total project cost of
  approximately $310 million, including interest during construction, project
  contingency costs and a debt service reserve fund.  The proposed capital
  structure is 75% debt, with a construction and term loan of approximately
  $225 million, and 25% equity, or approximately $85 million in equity
  contributions. The Company believes that political risk insurance from ExIm
  Bank for financing of the procurement of U.S. goods and services and, if
  appropriate, will request similar coverage from the Export-Import Bank of
  Japan for Japanese goods and services is available. The Company is in the
  process of arranging construction financing for the Project from a
  consortium of international banks, but may use some of the proceeds of this
  Offering to provide all or part of the interim construction debt

                                       46
<PAGE>
 
  financing of $225 million.  Construction of the Project is expected to
  commence in mid-year 1994, with commercial operation 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 contribution from these proceeds,
  and to arrange for political risk insurance on this investment through OPIC or
  from governmental agencies or commercial sources.

       The Manhanagdong 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 "EPC Contract").  The obligations
  of the EPC Consortium under the EPC Contracts will be supported by letters of
  credit, bonds, guarantees or other acceptable security in an aggregate amount
  equal to approximately 30% of the EPC Contracts' 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 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 Hydro Project

       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 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

                                       47
<PAGE>
 
       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.

       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

                                       48
<PAGE>
 
  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 the
  Ben Holt Co. 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 JOC and an 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, 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.

                                       49
<PAGE>
 
       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
"Business -- International Projects and Development Opportunities --
International 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 CED.  Through the year ended
December 31, 1993, the Company's portion of amounts paid by CED to Gilbert
under this contract was approximately $2.5 million.

     Aircraft Lease.  The Company is subleasing to Midwest Aviation, a division
of a subsidiary of Kiewit, an airplane leased by the Company from an
unaffiliated third-party aircraft lessor (the "Lessor").  The Company pays
monthly lease payments of $38,669 to the Lessor.  Midwest Aviation, in turn,
pays monthly sublease payments of $25,000 to the Company.  Both the lease and
the sublease terminate on July 31, 1995. Upon termination of the lease, the
Company has the right to purchase the aircraft; Midwest Aviation, in turn, has
the right to purchase the aircraft from the Company for the price paid by the
Company.

     The Company believes that the terms of the engineering and construction
contracts and sublease described above are comparable to available terms in
similar transactions with unaffiliated third parties.

     CERTAIN RELATIONSHIPS

     Mr. Scott, a director of the Company, is also the Chairman and President of
Kiewit, and owns Kiewit stock.  Mr. Crowe, a director of the Company, is the

Los Angeles office of Baker & McKenzie.  The Company paid to Baker & McKenzie a
total of approximately $615,636 in legal fees during 1993.

     The Company believes that the fees payable to Murphy and Demory, Ltd. and

of which this Prospectus is a part.  The following summary of certain provisions
of the Indenture does not purport to be complete and is subject to, and is
qualified in its entirety by reference to, all the provisions of the Indenture,
including the definitions of certain terms therein and those terms made a part
thereof by the Trust Indenture Act of 1939, as amended (the "Trust Indenture
Act").  Wherever particular Sections or defined terms of the Indenture are
referred to, such Sections or defined terms are incorporated herein by
reference.  A summary of certain defined terms used in the Indenture and
referred to in the following summary description of the Notes is set forth below
under "Certain Definitions."

GENERAL

     The Notes will be senior, unsecured obligations of the Company, will rank
pari passu with all other senior unsecured indebtedness of the Company, will be
limited to $[    ]  million aggregate principal amount and will mature on
January 15, 2004.

     The principal of, and premium, if any, on, the Notes will be payable, and
the Notes may be exchanged or transferred, at the office or agency of the
Company in the Borough of Manhattan, The City of New York (which initially will
be the corporate trust office of the Trustee).

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

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

                                     59

     The Company is subject to the informational reporting requirements of
Sections 13 and 15(d) under the Exchange Act and, in accordance therewith, files
certain reports and other information with the Commission.  See "Available
Information."  In addition, if Sections 13 and 15(d) cease to apply to the
Company, the Company will covenant in the Indenture to file comparable reports
and information with the Trustee and the Commission, and mail such reports and
information to Noteholders at their registered addresses, for so long as any
Notes remain outstanding.

OPTIONAL REDEMPTION

     The Notes may be redeemed at the Company's option, in whole or in part, at
any time on or after January 15, 1999 and prior to maturity, upon not less than
30 nor more than 60 days' prior notice, at the following redemption prices
(expressed in percentages of principal amount), plus accrued interest (if any)
to the date of redemption, if redeemed during the 12-month period commencing on
or after January 15 of the years set forth below:

<TABLE> 
<CAPTION> 
          Year                           Redemption Price

          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 $208.2 million. See "Capitalization" and
"Selected Historical Consolidated Financial and Operating Data." The Indenture
does not limit the amount of non-recourse indebtedness which may be incurred
at the subsidiary or project level. As a result, the Notes are effectively
subordinated to the indebtedness and other obligations of the

                                       60
<PAGE>
 
Company's subsidiaries and the partnerships and joint ventures in which the
Company has direct or indirect interests.  See "Investment Considerations --
Priority Project Debt."

CERTAIN COVENANTS

     The Indenture will contain certain covenants, including the ones
summarized below, which covenants will be applicable (unless they are waived or
amended or unless the Notes are defeased, see "Defeasance" below) so long as any
of the Notes are outstanding.

 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 provision set forth in the preceding paragraph,
(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) Debt outstanding as of the date of original
issuance of the Notes (other than Debt that is extinguished, retired, defeased
or repaid in connection with the original issuance of the Notes), including Debt
that is issued as interest in respect of 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.

                                       61
<PAGE>
 
 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 a direct or indirect interest therein owned by such Restricted
Subsidiary or Eligible Joint Venture, (iii) Non-Recourse Debt Incurred in
respect of a Permitted Facility in which such Restricted Subsidiary or such
Eligible Joint Venture has a direct or an indirect interest (which may include
Construction Financing provided by the Company pursuant to clause (ii) of the
definition of "Permitted Investment" below), (iv) Subsidiary Refinancing Debt,
(v) Acquired Debt and (vi) Debt in respect of Currency Protection Agreements or
Interest Rate Protection Agreements.

 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

                                       62
<PAGE>
 
to such fiscal quarter will be included pursuant to this clause (i), and
provided further that if Adjusted Consolidated Net Income for such period is
- -------- -------                                                            
less than zero, then minus 100% of the amount of such net loss, plus (ii) 100%
                     -----                                      ----          
of the aggregate net cash proceeds received by the Company from and after the
date of original issuance of the Notes from (A) the issuance and sale (other
than to a Restricted Subsidiary or an Eligible Joint Venture) of its Capital
Stock (excluding Redeemable Stock, but including Capital Stock other than
Redeemable Stock issued upon conversion of, or in exchange for Redeemable Stock
or securities other than its Capital Stock), (B) the issuance and sale or the
exercise of warrants, options and rights to purchase its Capital Stock (other
than Redeemable Stock) and (C) the issuance and sale of convertible Debt upon
the conversion of such convertible Debt into Capital Stock (other than
Redeemable Stock), but excluding the net proceeds from the issuance, sale,
exchange, conversion or other disposition of its Capital Stock (I) that is
convertible (whether at the option of the Company or the holder thereof or upon
the happening of any event) into (x) any security other than its Capital Stock
or (y) its Redeemable Stock or (II) that is Capital Stock referred to in clauses
(ii) and (iii) of the definition of "Permitted Payment", plus (iii) the net
                                                         ----              
reduction in Investments of the types specified in clauses (iv) and (v) of the
definition of "Restricted Payment" that result from payments of interest on
Debt, dividends, or repayment of loans or advances, the proceeds of the sale or
disposition of the Investment or other return of the amount of the original
Investment to the Company, the Restricted Subsidiary or the Eligible Joint
Venture that made the original Investment from the Person in which such
Investment was made, provided that (x) the aggregate amount of such payments
                     --------                                                
will not exceed the amount of the original Investment by the Company or such
Restricted Subsidiary that reduced the amount available pursuant to this clause
(c) for making Restricted Payments and (y) such payments may be added pursuant
to this clause (iii) only to the extent such payments are not included in the
calculation of Adjusted Consolidated Net Income, provided further that if
                                                 -------- -------        
Investments of the types specified in clauses (iv) and (v) of the Definition of
"Restricted Payment" have been made in any Person and such Person thereafter
becomes a Restricted Subsidiary, then the aggregate amount of such Investment
(to the extent that they have reduced the amount available pursuant to this
clause (c) for making Restricted Payments), net of the amounts previously added
pursuant to this clause (iii), may be added to the amount available for making
Restricted Payments.  The foregoing clause (c) will not prevent the payment of
any dividend within 60 days after the date of its declaration if such dividend
could have been made on the date of its declaration without violation of the
provisions of this covenant.

     None of the Company, any of its Restricted Subsidiaries or any Eligible
Joint Venture will be deemed to have made an Investment at the time that a
Person that is a Restricted Subsidiary of the Company or an Eligible Joint
Venture ceases to be a Restricted Subsidiary or an Eligible Joint Venture,
although any subsequent Investment made by the Company, its Restricted
Subsidiaries and Eligible Joint Ventures in such Person will be Investments
that will be subject to the foregoing paragraph unless and until such time as
such Person becomes a Restricted Subsidiary or an Eligible Joint Venture.
Notwithstanding the foregoing, the designation of a Restricted Subsidiary or
an Eligible Joint Venture as an

                                       63
<PAGE>
 
Unrestricted Subsidiary, as provided in the definition of "Unrestricted
Subsidiary," will be an Investment that will be subject to the foregoing
paragraph.

     Restricted Payments are defined in the Indenture to exclude Permitted
Payments, which include Permitted Investments.  See "Certain Definitions" below.

 Limitation on Dividends and Other Payment Restrictions Affecting Subsidiaries
 -----------------------------------------------------------------------------

     The Company will not, and will not permit any of its Restricted
Subsidiaries or any Eligible Joint Venture to, create or cause to become, or as
a result of the acquisition of any Person or Property or upon any Person
becoming a Restricted Subsidiary or an Eligible Joint Venture, remain subject
to, any consensual encumbrance or consensual restriction of any kind on the
ability of any Restricted Subsidiary or any Eligible Joint Venture to (a) pay
dividends or make any other distributions permitted by applicable law on any
Capital Stock of such Restricted Subsidiary or such Eligible Joint Venture owned
by the Company, any other Restricted Subsidiary or any other Eligible Joint
Venture, (b) make payments in respect of any Debt owed to the Company, any other
Restricted Subsidiary of the Company or any Eligible Joint Venture, (c) make
loans or advances to the Company or to any other Restricted Subsidiary of the
Company or any other Eligible Joint Venture that is directly or indirectly owned
by such  Restricted Subsidiary or such Eligible Joint Venture or (d) transfer
any of its Property to the Company or to any other Restricted Subsidiary or any
other Eligible Joint Venture that directly or indirectly owns or is owned by
such Restricted Subsidiary or such Eligible Joint Venture, other than those
encumbrances and restrictions created or existing (i) on the date of the
original issuance of the Notes, (ii) pursuant to the Indenture, (iii) in
connection with the Incurrence of any Debt permitted under the provisions
described in clause (iii) of the second paragraph of "Limitation on Subsidiary
Debt" above, provided that, in the case of Debt owed to Persons other than the
             --------                                                         
Company, its Restricted Subsidiaries and any Eligible Joint Venture, the
President or the Chief Financial Officer of the Company determines in good
faith, as evidenced by an Officers' Certificate, that such encumbrances or
restrictions are required to effect such financing and are not materially more
restrictive, taken as a whole, on the ability of the applicable Restricted
Subsidiary or the applicable Eligible Joint Venture to make the payments,
distributions, loans, advances or transfers referred to in clauses (a) through
(d) above than encumbrances and restrictions, taken as a whole, customarily
accepted (or, in the absence of any industry custom, reasonably acceptable) in
comparable financings or comparable transactions in applicable jurisdictions,
(iv) in connection with the execution and delivery of an electric power or
thermal energy purchase contract, or other contract related to the output or
product of, or services rendered by a Permitted Facility, to which such
Restricted Subsidiary or such Eligible Joint Venture is the supplying party or
other contracts with customers, suppliers and contractors to which such
Restricted Subsidiary or such Eligible Joint Venture is a party and where such
Restricted Subsidiary or such Eligible Joint Venture is engaged, directly or
indirectly, in the development, design, engineering, procurement, construction,
acquisition, ownership, management or operation of such Permitted Facility,
provided that the President
- --------                   

                                       64
<PAGE>
 
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 do 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

                                       65
<PAGE>
 
Business" below, and (iii) unless otherwise required under the terms of Senior
Debt, at the Company's election, the Net Cash Proceeds are either (A) invested
in the business of the Company, any of its Restricted Subsidiaries or any
Eligible Joint Venture or (B) applied to the payment of any Debt of the Company,
such Restricted Subsidiary or such Eligible Joint Venture (or as otherwise
required under the terms of such Debt) (other than Debt owed to the Company,
another Restricted Subsidiary or another Eligible Joint Venture by such
Restricted Subsidiary or such Eligible Joint Venture), provided that, no such
                                                       --------              
payment of Debt under Permitted Working Capital Facilities or any other
revolving credit agreement will be permitted unless the related loan commitment,
standby facility or the like will be permanently reduced by an amount equal to
the principal amount so repaid, provided further that such investment or such
                                -------- -------                             
payment, as the case may be, must be made within 365 days from the later of the
date of such Asset Disposition or the receipt by the Company, such Restricted
Subsidiary or such Eligible Joint Venture of the Net Cash Proceeds related
thereto.  Any Net Cash Proceeds from Asset Dispositions that are not applied as
provided in clause (A) or (B) of the preceding sentence will constitute "Excess
Proceeds."  Excess Proceeds will be applied, as described below, to make an
offer ("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 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

                                       66
<PAGE>
 
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 first sentence of
the first paragraph of this covenant, the Company may apply by such Net Cash
Proceeds pursuant to such provision.

     If the Notes tendered pursuant to an Offer have an aggregate purchase
price that is less than the Excess Proceeds available for the purchase of the
Notes, the Company may use the remaining Excess Proceeds for general corporate
purposes without regard to the provisions of this covenant.  The Company will
not be required to make an Offer for Notes if the Excess Proceeds available
therefor are less than $10 million, provided, that the lesser amounts of such
                                    --------                                 
Excess Proceeds will be carried forward and cumulated for each 36 consecutive
month period for purposes of determining whether an Offer is required with
respect to any Excess Proceeds of any subsequent Asset Dispositions.  Any such
lesser amounts so carried forward and cumulated need not be segregated or
reserved and may be used for general corporate purposes, provided that such use
                                                         --------              
will not reduce the amount of cumulated Excess Proceeds or relieve the Company
of its obligation hereunder to make an Offer with respect thereto.

     The Company will make an Offer by mailing to each Holder, within 30 days
from the receipt of Excess Proceeds that cause the cumulated Excess Proceeds
to exceed $10 million, a written notice that will specify the purchase date,
which will not be less than 30 days nor more than 60 days after the date of
such notice (the "Purchase Date"), and that will contain certain information
concerning the business of the Company that the Company believes in good
faith will enable the Holders to make an informed decision. Holders that elect

                                       67
<PAGE>
 
to have their Notes purchased will be required to surrender such Notes at least
one Business Day prior to the Purchase Date.  If at the expiration of the Offer
period the aggregate purchase price of the Notes tendered by Holders and
purchased pursuant to the Offer exceeds the amount of such Excess Proceeds, the
Notes or portions of Notes to be accepted will be selected by the Trustee in
such manner as the Trustee deems to be fair and appropriate in the
circumstances.

     If the Company is prohibited by applicable law from making the Offer or
purchasing Notes thereunder, the Company need not make an Offer for so long as
such prohibition is in effect.

     The Company will comply with all applicable tender offer rules,
including, without limitation, Rule 14e-1 under the Exchange Act, in
connection with an Offer.

 Limitation on Transactions with Affiliates

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 or such Restricted Subsidiary, or such
Eligible Joint Venture than those that could be obtained in a comparable arm's
length transaction with a Person that is not such an Affiliate and (iii) (a)
with respect to such business, transaction or series of related transactions
that has a fair market value or involves aggregate payments equal to, or in
excess of, $10 million but less than $25 million, the Company delivers to the

officer's belief that such business, transaction or series of related
transactions complies with clauses (i) and (ii) above, and (b) with respect to
such business, transaction or series of related transactions that has a fair
market value or involves aggregate payments equal to, or in excess of, $25
million such business, transaction or series of transactions is approved by a
majority of the Board of Directors (including a majority of the disinterested
directors), which approval is set forth in a Board resolution delivered to the
Trustee certifying that, in good faith, the Board of Directors believes that
such business, transaction or series of transactions complies with clauses (i)
and (ii) above.

 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 a 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

                                       70
<PAGE>
 
of business on the Purchase Date, (7) that a Holder will be entitled to withdraw
such Holder's election if the paying agent receives, not later than the close of
business on the third Business Day (or such shorter periods as may be required
by applicable law) preceding the Repurchase Date, a telegram, telex, facsimile
transmission or letter setting forth the name of the Holder, the principal
amount of Notes the Holder delivered for purchase, and a statement that such
Holder is withdrawing his election to have such Notes purchased and (8) that
Holders that elect to have their Notes purchased only in part will be issued new
Notes having a principal amount equal to the portion of the Notes that were
surrendered but not tendered and purchased.

     On the Purchase Date, the Company will (i) accept for payment all Notes
or portions thereof tendered pursuant to the Change of Control Offer, (ii)
deposit with the Trustee money sufficient to pay the purchase price of all
Notes or portions thereof so tendered for purchase and (iii) deliver or cause
to be delivered to the Trustee the Notes properly tendered together with an
Officers' Certificate identifying the Notes or portions thereof tendered to
the Company for purchase. The Trustee will promptly mail to the Holders of the
Notes properly tendered payment in an amount equal to the purchase price, and
promptly authenticate and mail to each Holder a new Note having a principal
amount equal to any portion of such Holder's Notes that were surrendered but
not tendered and purchased, the Company will publicly announce the results of
the Change of Control Offer on or as soon as practicable after the Purchase
Date.

     If the Company is prohibited by applicable law from making the Change of
Control Offer or purchasing Notes thereunder, the Company need not make a
Change of Control Offer for so long as such prohibition is in effect.

     The Company will comply with all applicable tender offer rules,
including, without limitation, Rule 14e-1 under the Exchange Act, in
connection with a Change of Control Offer.

of the Company and its consolidated Restricted Subsidiaries (as determined in

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.

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

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

                                       75
<PAGE>
 
delivered to the effect described in clause (B)(ii)(y) below), and the
provisions of the Indenture will cease to be applicable with respect to the
Notes (except for, among other matters, certain obligations to register the
transfer or exchange of the Notes, to replace stolen, lost or mutilated Notes,
to maintain paying agencies and to hold monies for payment in trust) if, among
other things, (A) the Company has deposited with the Trustee, in trust, money
and/or U.S. Government Obligations that through the payment of interest and
principal in respect thereof in accordance with their terms will provide money
in an amount sufficient to pay the principal of, premium, if any, and accrued
interest on the Notes, on the Stated Maturity of the Notes or, if the Company
makes arrangements satisfactory to the Trustee for the redemption of the Notes
prior to their Stated Maturity, on any earlier Redemption Date in accordance
with the terms of the Indenture and the Notes, (B) the Company has delivered to
the Trustee (i) either (x) an Opinion of Counsel to the effect that Holders will
not recognize income, gain or loss for federal income tax purposes as a result
of such deposit, defeasance and discharge and will be subject to federal income
tax on the same amount and in the same manner and at the same times as would
have been the case if such deposit, defeasance and discharge had not occurred
and the Company had paid or redeemed such Notes on the applicable dates, which
Opinion of Counsel must be based upon a ruling of the Internal Revenue Service
to the same effect or a change in applicable federal income tax law or related
Treasury regulations after the date of the Indenture or (y) a ruling directed to
the Trustee received from the Internal Revenue Service to the same effect as the
aforementioned Opinion of Counsel, (ii) an Opinion of Counsel to the effect that
the creation of the defeasance trust does not violate the Investment Company Act
of 1940 and (iii) an Opinion of Counsel to the effect that either (x) after the
passage of 123 days following the deposit, the trust fund will not be subject to
the effect of Section 547 or 548 of the U.S Bankruptcy Code or Section 15 of the
New York Debtor and Creditor Law or (y) based upon existing precedents, if the
matter were properly briefed, a court should hold that the deposit of moneys
and/or U.S. Government Obligations as provided in clause (A) would not
constitute a preference voidable under Section 547 or 548 of the U.S. Bankruptcy

 Covenant Defeasance
 -------------------

     The Indenture further provides that the provisions of clause (iii) under
"Mergers, Consolidations and Sales of Assets" and all the covenants described
herein under "Certain Covenants," clause (iv) under "Events of Default" with
respect to such covenants and with respect to clause (iii) under "Mergers,
Consolidations and Sales of Assets," and clauses (iii) and (v) under "Events
of Default" will cease to be applicable to the Company and its Subsidiaries
upon the satisfaction of the provisions described in clauses (A), B(ii) and
(iii), (C) and (D) of the preceding paragraph and the delivery by the Company
to the Trustee of an Opinion of Counsel to the effect that, among other
things, the Holders of the Notes will not recognize income, gain or loss for
federal income tax purposes as a result of such deposit and the defeasance of
certain covenants and Events of Default and will be subject to federal income
tax on the same amount and in the same manner and at the same times as would
have been the case if such deposit and defeasance had not occurred and the
Company had paid or redeemed such Notes on the applicable dates.

 Defeasance and Certain Other Events of Default
 ----------------------------------------------

     If the Company exercises its option to omit compliance with certain
covenants and provisions of the Indenture with respect to the Notes as described
in the immediately preceding paragraph and the Notes are declared due and
payable because of the occurrence of an Event of Default that remains
applicable, the amount of money and/or U.S. Government Obligations on deposit
with the Trustee will be sufficient to pay amounts due on the Notes at the time
of their Stated Maturity or scheduled redemption, but may not be sufficient to
pay amounts due on the Notes at the time of acceleration resulting from such
Event of Default.  The Company will remain liable for such payments.

THE TRUSTEE

     IBJ Schroder Bank & Trust Company is the Trustee under the Indenture.

GOVERNING LAW

     The Indenture and the Notes will be governed by, and construed in
accordance with, the law of the State of New York, including Section 5-1401 of

of laws rules.

                   CERTAIN FEDERAL INCOME TAX CONSIDERATIONS
                                        
GENERAL

     The following is a summary, based on the opinion of Willkie Farr &
Gallagher, counsel to the Company, of the anticipated material United States
federal income tax consequences of the purchase, ownership and disposition of
the Notes.  This summary is based upon the Internal Revenue Code of 1986, as
amended (the "Code"), its legislative history, existing and proposed regulations
thereunder, published rulings and court decisions, all as in effect and existing
on the date of this Prospectus and all of which are subject to change at any
time, which change may be retroactive.  In particular, the discussion below of
"Original Issue Discount" is based in part on proposed regulations released on
December 22, 1992, but not yet effective (the "Proposed OID Regulations").
While the 1992 Proposed OID Regulations are proposed to be effective for debt
instruments issued sixty or more days after final regulations are issued and
therefore may not be applicable to the Notes, the 1992 Proposed OID Regulations
are the most current indication of the views of the Internal Revenue Service
(the "Service") with respect to the federal income tax treatment of debt
instruments having original issue discount ("OID").

     Unless otherwise specified, the discussion below assumes that the rules set
forth in the Proposed OID Regulations will control the tax treatment of the
Notes.  However, changes may be made to the Proposed OID Regulations or final
OID regulations may be adopted that would apply to the Notes and that may be
contrary to the interpretations of the Proposed OID Regulations discussed below.
Because of the lack of definitive regulatory authority, no assurance can be
given that the Service will agree with the interpretations of the Proposed OID
Regulations discussed below or that the final OID regulations will not differ
materially from the Proposed OID Regulations or subsequent versions thereof.

     This summary applies only to those persons who are the initial Holders of
the Notes and who hold Notes as capital assets and does not address the tax
consequences to taxpayers who are subject to special rules (such as financial
institutions, tax-exempt organizations and insurance companies) or aspects of
federal income taxation that may be relevant to a prospective investor based
upon such investor's particular tax situation. Accordingly, purchasers of Notes
should consult their own tax advisors with respect to the particular
consequences to them of the purchase, ownership and disposition of the Notes,
including the applicability of any state, local or foreign tax laws to which
they may be subject as well as with respect to the possible effects of changes
in federal and other tax laws.

ORIGINAL ISSUE DISCOUNT

     General.  Because the Notes are being issued at a discount from their
"stated redemption price at maturity," the Notes will have OID for federal
income tax purposes.  For federal income tax purposes, OID on a Note will be the
excess of the stated redemption price at maturity of the Note over its issue
price. Because the Notes will be treated as being publicly offered under the
Proposed OID Regulations, the issue price of the Notes will be the first price
to the public (excluding bond houses and brokers) at which a substantial amount
of Notes is sold.

                                      101
<PAGE>
 
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 _______________, 1997, the interest
payments on the Notes will not constitute qualified stated interest and thus
will be included along with principal in the stated redemption price at maturity
of the Notes.  As a result, each Note will bear OID in an amount equal to the
excess of (i) the sum of its principal amount and all stated interest payments
over (ii) its issue price.

     A Holder will be required to include OID in income periodically over the
term of a Note before receipt of the cash or other payment attributable to such
income.  In general, a Holder must include in gross income for federal income
tax purposes the sum of the daily portions of OID with respect to the Note for
each day during the taxable year or portion of a taxable year on which such
Holder holds the Note ("Accrued OID").  The daily portion is determined by
allocating to each day of any accrual period within a taxable year a pro rata
portion of an amount equal to the adjusted issue price of the Note at the
beginning of the accrual period multiplied by the yield to maturity of the Note.
For purposes of computing OID, the Company will use six-month accrual periods
that end on the days in the calendar year corresponding to the maturity date of
the Notes and the date six months prior to such maturity date, with the
exception of an initial short accrual period.  The adjusted issue price of a
Note at the beginning of any accrual period is the issue price of the Note
increased by the Accrued OID for all prior accrual periods (less any cash
payments on the Notes). Under these rules, Holders may have to include in gross
income increasingly greater amounts of OID in each successive accrual period.

     Optional Redemption.  If the Company exercises its rights to redeem the
Notes (See "Description of the Notes -- Optional Redemption), the tax treatment
of the redemption would be governed by the rules for dispositions generally.
See "Disposition of the Notes."  However, if the Company were found to have an
intention at the time the Notes were issued to redeem them before maturity, any
taxable income arising from such redemption would be treated as ordinary income
to the extent of any unamortized OID.

     If a Holder tenders Notes for redemption as a result of a Change of Control
(See "Description of the Notes -- Change of Control"), the Holder may be
required to include as ordinary income any amount the Holder is entitled to
receive in excess of the Accreted Value of a Note on the date of the redemption.
Holders should consult their own tax advisors regarding the treatment of
payments upon optional redemptions.

DISPOSITION OF THE NOTES

     Generally, any sale or redemption of the Notes will result in taxable gain
or loss equal to the difference between the amount of cash or other property
received and the Holder's adjusted tax basis in the Note.  A Holder's adjusted
tax basis for determining gain or loss on the sale or other disposition of a
Note will initially equal the cost of the Note to such Holder and will be
increased by any Accrued OID (and, as described below, any market discount)
includible

                                      102
<PAGE>
 
in such Holder's gross income and decreased by the amount of any cash payments
received by such Holder regardless of whether such payments are denominated as
principal or interest.  Except to the extent that the market discount rules
described below apply, any gain or loss upon a sale or other disposition of a
Note will generally be capital gain or loss, which will be long term if the Note
has been held by the Holder for more than one year.

     Market Discount.  Generally, market discount will exist to the extent the
purchase price paid by a Holder for a Note is less than the issue price of the
Note at the time of purchase, subject to a statutory de minimis exception.
Generally, a Holder of a Note who acquires the Note with market discount will be
required to treat any gain realized upon the disposition of such Note as
ordinary income to the extent of the market discount that accrued (but was not
previously included in income) during the period such Holder held the Note.
Furthermore, the Code requires that partial principal payments on a market
discount bond be included in gross income to the extent that such payments do
not exceed the accrued market discount on such bond.  Thus, if a cash payment is
received by a Holder, such Holder will be required to include in income at the
time such cash payment is received the portion of the unrecognized market
discount that accrued prior to the receipt of such cash payment (up to the
amount of such payment).  A Holder of a Note who has acquired the Note with
market discount may also be required to defer deduction of a portion of interest
on debt incurred or continued to purchase or carry the Note until disposition of
the Note in a taxable transaction.

     A Holder may elect to include market discount in income as such discount
accrues with a corresponding increase in the Holder's tax basis in the Note.  If
a Holder so elects, the rules in the preceding paragraph regarding the treatment
of income or gain upon the disposition of a Note and upon receipt of certain
cash payments as ordinary income or gain, and regarding the deferral of interest
deductions on indebtedness related to a Note, would not apply.  Once made, such
an election applies to all debt obligations that are purchased by the Holder at
a market discount during the taxable year for which the election is made, and
all subsequent taxable years of the Holder, unless the Service consents to a
revocation of the election.

     Acquisition Premium.  A Holder of a Note who acquires such Note at a cost
in excess of its issue price will be considered to have purchased such Note at
an "acquisition premium."  Under the acquisition premium rules contained in the
Code, generally, such Holder would be entitled to a reduction in the amount of
OID otherwise includible in income with respect to such Note.

CERTAIN FEDERAL INCOME TAX CONSEQUENCES TO THE COMPANY AND TO CORPORATE HOLDERS

     The Notes will constitute "applicable high yield discount obligations"
("AHYDOs") if the yield to maturity of such Notes is equal to or greater than
the sum of the relevant applicable federal rate (the "AFR"), plus five
percentage points.  The AFR applicable to the Notes is ___%, compounded
semiannually.  Accordingly, if the yield to maturity of the Notes is equal to or
greater than ____%, the Notes will constitute AHYDOs.  If the Notes are AHYDOs,
as described below, a portion of the tax deductions that would otherwise be
available to the Company in respect of the Notes will be deferred or disallowed,
which, in turn, might reduce the after-tax

                                      103
<PAGE>
 
cash flows of the Company.  More particularly, if the Notes constitute AHYDOs,
the Company will not be entitled to deduct OID that accrues with respect to such
Notes until amounts attributable to OID are paid in cash.  In addition, if the
yield to maturity of the Notes exceeds the sum of the relevant AFR plus six
percentage points (the "Excess Yield"), the "disqualified portion" of the OID
accruing on the Note will be characterized as a non-deductible dividend with
respect to the Company and also may be treated as a dividend distribution solely
for purposes of the dividends received deduction of Sections 243, 246 and 246A
of the Code with respect to Holders that are U.S. corporations.

     In general, the "disqualified portion" of OID for any accrual period will
be equal to the product of (i) a percentage determined by dividing the Excess
Yield by the yield to maturity and (ii) the OID for the accrual period.  Subject
to otherwise applicable limitations, such a corporate Holder will be entitled to
a dividends received deduction (generally at a 70% rate) with respect to the
disqualified portion of the Accrued OID if the Company has sufficient current or
accumulated "earnings and profits."  To the extent that the Company's earnings
and profits are insufficient, any portion of the OID that otherwise would have
been recharacterized as a dividend for purposes of the dividends received
deduction will continue to be taxed as ordinary OID income in accordance with
the rules described above in "Original Issue Discount."  Treatment of the Notes
as AHYDOs will not disqualify interest or OID with respect to the Notes from the
portfolio interest exception described below under "Foreign Holders," provided
all applicable requirements for the exception are otherwise satisfied.

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

                                      104
<PAGE>
 
corporation or partnership created or organized in the United States or under
the law of the United States or any state or (iii) an estate or trust, the
income of which is includable in gross income for United States federal income
tax purposes regardless of its source, but only if the income or gain on the
Note is not effectively connected with the conduct of a trade or business within
the United States by such Holder.  If the income or gain on the Note is
effectively connected with the conduct of a trade or business within the United
States, then the nonresident alien individual or foreign corporation will be
subject to tax on such income or gain in essentially the same manner as a U.S.
citizen or resident or a domestic corporation, as discussed above, and in the
case of a foreign corporation, may also be subject to the branch profits tax
(unless such branch profits tax is reduced or eliminated under an applicable
treaty).

     Under the "portfolio interest" exception to the general rules for the
withholding of tax on interest and OID paid to a Foreign Person, a Foreign
Person will not be subject to U.S. tax (or to withholding) on interest or OID on
a Note, provided that (i) the Foreign Person does not actually or constructively
own 10% or more of the total combined voting power of all classes of stock of
the Company entitled to vote and is not a controlled foreign corporation with
respect to the United States that is related to the Company through stock
ownership, and (ii) the Company, its paying agent or the person who would
otherwise be required to withhold tax receives either (A) a statement (an
"Owner's Statement") signed under penalties of perjury by the beneficial owner
of the Note in which the owner certifies that the owner is not a U.S. person and
which provides the owner's name and address, or (B) a statement signed under
penalties of perjury by the Financial Institution holding the Note on behalf of
the beneficial owner, together with a copy of the Owner's Statement.  The term
"Financial Institution" means a securities clearing organization, bank or other
financial institution that holds customers' securities in the ordinary course of
its trade or business and that holds a Note on behalf of the owner of the Note.
A Foreign Person who does not qualify for the "portfolio interest" exception
would, under current law, generally be subject to U.S. withholding tax at a flat
rate of 30% (or a lower applicable treaty rate) on interest payments and
payments (including redemption proceeds) attributable to OID on the Notes.

     In general, gain recognized by a Foreign Person upon the redemption, sale
or exchange of a Note (including any gain representing accrued market discount)
will not be subject to U.S. tax.  However, a Foreign Person may be subject to
U.S. tax at a flat rate of 30% (unless exempt by an applicable treaty) on any
such gain if the Foreign Person is an individual present in the United States
for 183 days or more during the taxable year in which the Note is redeemed, sold
or exchanged, and certain other requirements are met.

</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 less a selling concession not to exceed ____% of the principal
amount of the Notes.  The selected dealers may reallow a concession to certain
other dealers not to exceed ____% of the principal amount of the Notes.  After
the initial public offering of the Notes, the public offering price, the
concession to selected dealers and the reallowance to other dealers may be
changed by the Underwriters.

     The Company intends to list the Notes for trading on the New York Stock
Exchange.  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.

     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.

     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.
McArthur, Senior Vice President and General Counsel of the Company, and by

                                    EXPERTS

     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".

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
for the three years ended December 31, 1993
dollars and shares in thousands, except per share amounts

- --------------------------------------------------------------------------------
1.  BUSINESS

    California Energy Company, Inc. (the Company or CECI) 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 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 these 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 Joint Ventures after payout. Payout
    is achieved when a Joint Venture has returned the initial capital to the
    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 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 CECI'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.

                                      F-7
<PAGE>
 
    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 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 Joint Ventures in which the
    Company has invested is deferred until each Joint Venture commences
    operations. Revenue previously deferred is amortized over the lives of the
    related assets of the Joint Ventures as each 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.

                                      F-8

    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 international 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.

    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 or
    CFP), Coso Energy Developers (BLM or CED), and Coso Power Developers (Navy
    II or CPD). 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 PLANT I

    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
    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 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 CED's 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 7.6% 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 CFP, CED
    and CPD commenced under those contracts in 1987, 1989 and 1990,
    respectively.

================================================================================
</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.

    The property acquired from Chevron includes a 9MW power plant at Desert
    Peak, Nevada ("Desert Peak"), and a 70% interest in a steam field at
    Roosevelt Hot Springs, Utah ("Roosevelt"). 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 6.3 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 Roosevelt Hot Springs site has a
    contract to sell steam to a 25MW 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
                                     F-11
<PAGE>
 
    Roosevelt 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 through an equity
    offering, a $20,317 pre-sale of steam from the Roosevelt field to the
    utility-owned power plant located at the site, and seller financing. The
    acquisition of Roosevelt 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); see Note 12.

5.  PROJECT LOANS

Project loans, which are non-recourse to the Company, comprise the following at
December 31:
<TABLE> 
<CAPTION> 

                                                           1993           1992
- --------------------------------------------------------------------------------
    <S>                                                <C>           <C> 
    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,
    collectively the "Joint Ventures". Pursuant to separate credit agreements
    executed between Funding Corp. and each Joint Venture on December 16, 1992,
    the proceeds from Funding Corp.'s note offering were loaned to the Joint
    Ventures. The proceeds of $560,245 were used by the 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 Joint Ventures to third
    parties to discharge all liens of record and other contract claims
    encumbering the 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
    Coso Funding Corp., and such establishment did not reflect the Joint
    Ventures' view as to the merits or likely disposition of such litigation or
    other contingencies. On June 9, 1993, MPE and the Mission Power Group,
    subsidiaries of SCECorp., and the Coso Joint Ventures reached a final
    settlement of all of their outstanding disputes and claims relating to the
    construction of the Coso Project. As a result of the various payments and
    releases involved in such settlement, the Coso Joint Ventures agreed to make
    a net payment of $20,000 to MPE from the cash reserves of the Coso Project
    contingency fund and MPE agreed to release its mechanics' liens on the Coso
    Project. After making the $20,000 payment, the remaining balance of the Coso
    Project contingency fund (approximately $49,300) was used to increase the
    Coso Project debt reserve fund from approximately $43,000 to its maximum
    fully-funded requirement of $67,900. The remaining $24,400 balance of
    contingency fund was retained within the Coso Project for future capital
    expenditures and for Coso Project debt service payments. Since the Coso
    Project debt service reserve is fully funded in advance, Coso Project cash
    flows otherwise intended to fund the Coso Project debt service reserve fund,
    subject to satisfaction of certain covenants and conditions contained in the
    Coso Joint Ventures' refinancing documents, may be available for
    distribution to the Company in its proportionate share.

    The loans are collateralized by, among other things, the power plants,
    geothermal resource, debt service reserve funds, contingency funds, pledge
    of contracts, and an assignment of all such Joint Ventures' revenues which
    will be applied against the payment of obligations of each Joint Venture,
    including the project loans. Each Joint Venture's assets will secure only
    its own project loan, and will not be cross-collateralized with assets
    pledged under other Joint Venture's

                                     F-12
<PAGE>
 
    credit agreements. The project loans are non-recourse to any partner in the
    Joint Ventures and Funding Corp. shall solely look to such Joint Venture's
    pledged assets for satisfaction of such project loans. However, the loans
    are cross-collateralized by the available cash flow of each Joint Venture.
    Each 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 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

                                     F-13
<PAGE>
 
    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 is 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.

    Provision for income tax was comprised of the following at December 31:

    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.

    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

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 (See Note 12) would not trigger the exercise of the rights. The
    rights will expire, unless previously redeemed or exercised, on November 30,
    1998. The rights are automatically attached to, and trade with, each share
    of common stock.

    Series B:
    ---------

    On November 15, 1990, the Company sold 357.5 shares of convertible preferred
    stock, Series B at $14 per share. Each share of the convertible preferred
    stock was convertible into two shares of common stock, and had a dividend
    rate of 15% through November 15, 1992, 10% from November 16, 1992 to
    November 15, 1994 and 5% from November 16, 1994 to November 15, 1996. The
    dividends were payable semi-annually in convertible preferred stock, Series
    B.

    On November 15, 1992, the Company called the preferred stock for conversion
    into common stock. Each Series B preferred stock was converted into two
    shares of common stock; accordingly, the Company issued 954.9 shares of
    common stock.

    Series C:
    ---------

    On November 19, 1991, the Company sold one thousand shares of convertible
    preferred stock, Series C at $50,000 per share to Kiewit, 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.

                                     F-16
<PAGE>
 
    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
    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 approximately 138 options to consultants
    on terms similar to those issued under the 1986 Plan. The non-1986 plan
    options are primarily options granted to Kiewit; see Note 12.

    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 signed a Stock Purchase Agreement and related
    agreements, dated as of February 18, 1991. Kiewit 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 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
    also entered into certain other agreements pursuant to which (i) Kiewit
    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 became entitled to nominate at least three of the Company's
    directors, and (iii) the Company and Kiewit 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 the rights to develop the
    Nevada and Utah properties, and Kiewit 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 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 of one thousand shares of Series C Preferred Stock for $50,000, as
    described in Note 10 above. In connection with the sale of the Series C
    Preferred

                                    F-19
<PAGE>
 
    Stock to Kiewit, 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 Joint Ventures in connection with the turnkey contracts for the
    design and construction on eight of the units. In July 1990, MPE, the
    Joint Venture Partners and the Company agreed to enter settlement
    discussions during which period the suit was suspended. In January 1991,
    MPE terminated settlement discussions and refiled its suit in the amount
    of approximately $70,900 in contract claims. The 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 Joint
    Ventures' maximum exposure for the cost of the construction of a new 220kV
    electric transmission line (Line) on the SCE transmission system. The
    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 Joint Ventures' share would be approximately
    $7,000. The 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 Joint Ventures and deducted amounts from revenues
    payable under the power purchase contracts. The 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 geothermal 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 (Mission
    Energy, Mission Power, Southern California Edison) 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.

    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 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 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 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 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

                                    F-21

    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.

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.

     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

                                     II-2
<PAGE>
 
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 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.

mission thereunder and shall not contain an untrue statement of a material fact
or omit to state a material fact required to be stated therein or necessary to

          (d)  The Company, each Subsidiary (as defined below) and each Joint
Venture (as defined below) have been duly organized and are validly existing
and, if applicable, in good standing under the laws of their respective
jurisdictions of organization as a corporation or partnership, as the case may
be, and have the power and authority to own, lease and operate their property
and conduct their businesses as described in the Prospectus; the Company, the
Subsidiaries and the Joint Ventures are duly qualified to do business and are in
good standing as foreign corporations or foreign partnerships, as the case may
be, in each jurisdiction, domestic or foreign, in which such registration or
qualification or good standing is required (whether by reason of the ownership
or leasing of property, the conduct of business or otherwise), except where the
failure to so register or qualify or be in good standing would not have a
material adverse effect on the financial condition or results of operations of
the Company and its Subsidiaries taken as a whole; and the Company has all
requisite power and authority to enter into this Agreement and the Indenture,
and to consummate the transactions contemplated hereby and thereby.  For
purposes of this Agreement, (A) the term "Subsidiary" shall mean Coso Hotsprings
Intermountain Power, Inc., China Lake Operating Company and Coso Technology
Corporation, each a Delaware corporation, and the other subsidiaries listed on
Schedule 2 hereto, and (B) the term "Joint Venture" shall mean the Permitted
Joint Ventures and the Eligible Joint Ventures (as such terms are defined in the
Indenture) and Coso Finance Partners ("CFP"), Coso Energy Developers ("CED") and
Coso Power Developers ("CPD"), each a California general partnership, it being
understood that such term means the general partnership entity and not the
individual general partners thereof.  The Subsidiaries listed above and on
Schedule 2 are all the direct and indirect "subsidiaries" of the Company, as
such term is defined in Rule 405 of the Rules and Regulations.

          (e)  The Company has an authorized and outstanding capitalization as
set forth in the Prospectus; all the issued and outstanding shares of capital

                                       4

stock of the Company have been validly authorized and issued and are fully-paid
and nonassessable; all the outstanding shares of capital stock of each
Subsidiary have been duly and validly authorized and issued and are fully-paid
and nonassessable; and except as otherwise set forth or referred to in the
Prospectus, all outstanding shares of capital stock of each Subsidiary are owned
beneficially by the Company free and clear of any material claims, liens,
encumbrances and security interests.  As of the date of this Agreement and the
Delivery Date (as defined below), the Company is the beneficial owner of
approximately 46%, 48% and 50% of the outstanding partnership interests of CFP,
CED and CPD, respectively.  All of such interests beneficially owned by the
Company have been duly and validly authorized and issued and, except as
otherwise disclosed or referred to in the Prospectus, are owned beneficially by
the Company free and clear of any material claims, liens, encumbrances and
security interests.

          (f)  The Notes have been duly authorized by the Company, and,
when duly executed, authenticated, issued and delivered against payment as
contemplated hereby and by the Indenture shall be validly issued and
outstanding, and shall constitute valid and binding obligations on the part 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 applicable bankruptcy, fraudulent conveyance, insolvency,
reorganization, moratorium or other similar laws affecting creditors' rights
generally and by equitable principles generally; and the Notes conform in all
material respects to the descriptions thereof contained in the Prospectus.

          (g)  The Indenture has been duly authorized, and when duly executed
and delivered by the Company, shall constitute a valid and binding agreement on
the part of the Company, enforceable against the Company in accordance with its
terms, except as enforcement may be limited by applicable bankruptcy, fraudulent
conveyance, insolvency, reorganization, moratorium or other similar laws
affecting creditors' rights generally and by equitable principles generally;
and the Indenture conforms in all material respects to the descriptions thereof
contained in the Prospectus.

by the Company, and constitutes a valid and binding agreement on the part of
the Company, enforceable against the Company in accordance with its terms,
except as enforcement may be limited by applicable bankruptcy, fraudulent
conveyance, insolvency, reorganization, moratorium or other similar laws affect-
ing creditors' rights generally and by equitable principles generally.

          (i)  The execution, delivery and performance of this Agreement
and the Indenture, the consummation of the transactions contemplated herein and
therein and the issuance and delivery of the Notes shall not (i) conflict with
the corporate charter or by-laws or partnership agreement of the Company, any
Subsidiary or any Joint Venture, (ii) conflict with, result in the creation or
imposition of any lien, charge or other encumbrance upon any asset with a value
in excess of $10,000,000 (a "Material Asset") of the Company, any Subsidiary or

     is in good standing as a foreign corporation or a foreign partnership, as

     registration, qualification or good standing is required (whether by
     reason of the ownership or leasing of property, the conduct of its
     business or otherwise), except where failure to so register or qualify or
     be in good standing would not have a material adverse effect on the
     financial condition or results of operation of the Company and its
     Subsidiaries taken as a whole;

               (iii)  The Company has the authorized and outstanding

     contractual interests in, all items of real and personal property that
     are material to the business of such entity, free and clear of all liens,

     action, suit or proceeding before any court or governmental agency or body,
     domestic or foreign, now pending or threatened against or affecting the
     Company, any Subsidiary or any Joint Venture, that is reasonably expected
     to result in any material adverse change in the financial condition or
     results of operations of the Company and its Subsidiaries taken as a
     whole, or is reasonably expected to materially and adversely affect the
     consummation of the transactions contemplated by this Agreement;

     tions are in full force and effect, and the Company, the Subsidiaries and
     the Joint Ventures are in compliance therewith, except with respect to (A)

     obtain would not have a material adverse affect on the financial condition
     or results of operations of the Company and its Subsidiaries taken as a
     whole, (B) permits, consents and approvals that may be required for future
     drilling or operating activities that are ordinarily deemed to be

     and the Rules and Regulations, and the documents incorporated by reference

     provisions of the Indenture, the Certificate of Incorporation of the
     Company and the Notes, (B) "The Business of the Company -- Legal
     Proceedings" to the extent that they constitute matters of law or legal

     opinion as if it were addressed to them;

               (xiii)  To the best of 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

               (xvi)  The Notes have been (A) duly authorized by the Company,
     (B) duly authenticated by the Trustee, and (C) duly executed, issued and

               (xvii)  None of the Company, any Subsidiary or any Joint Venture
     is in violation of its respective charter, by-laws or partnership

     observance of any obligation, agreement, covenant or condition contained in

     to the Indenture do not and shall not result in any violation of the
     charter or by-laws of the Company, and do not and shall not conflict with,
     violate or constitute a breach of, or default under, or result in the
     creation or imposition of any tax, lien, charge or encumbrance upon any
     revenues, property or assets of the Company, any Subsidiary or any Joint
     Venture pursuant to, (A) any applicable treaty, law, rule or regulation,
     (B) any applicable judgment, order or decree of any government,
     governmental instrumentality or court, domestic or foreign, having

     of their respective properties or assets or (C) any contract, indenture,
     mortgage, loan, agreement, note, license, lease or other agreement or

     party or by which it or any of them may be bound, or to which any of the
     property or assets of the Company, any Subsidiary or any Joint Venture is
     subject (other than any such conflicts, violations, breaches, defaults,
     creations or impositions as individually or in the aggregate would not have
     a material adverse affect on the financial condition or results of
     operations of the Company and its Subsidiaries taken as a whole);

               (xix)  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

     with the issuance and sale of the Notes hereunder, except as may be
     required under  applicable state securities laws in connection with the
     purchase and distribution of the Notes by the Underwriters;

               (xx)  To the best of such counsel's knowledge, there are no
     contracts, agreements or understandings between the Company and any person
     granting such person the right to require the Company to file a
     registration statement under the Securities Act with respect to any
     securities of the Company owned or to be owned by such person or to require
     the Company to include such securities in

                                       25
<PAGE>
 
     the securities registered pursuant to the Registration Statement or in any
     securities being registered pursuant to any other registration statement
     filed by the Company under the Securities Act; and

               (xxi)  The Company is not, and after giving effect to the
     issuance of the Notes and the application of the proceeds therefrom shall
     not be, an "investment company," or, to the best of such counsel's
     knowledge, a company "controlled" by an "investment company," within the
     meaning of the 1940 Act.

          In the rendering of such opinion, 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 and the General
Corporation Law of the State of Delaware and that such counsel is not admitted
in the State of Delaware and (ii) in giving the opinion referred to in Section
7(d)(v), state that no examination of record titles for the purpose of such
opinion has been made and that they are relying upon a general review of the
titles of the Company and its Subsidiaries and the Joint Ventures, upon
opinions of local counsel and abstracts, reports and policies of title
companies rendered or issued at or subsequent to the time of acquisition of such
property by the Company, the Subsidiaries or the Joint Ventures, upon opinions
of counsel to the lessors of such property and, in respect of matters of fact,
upon certificates of officers of the Company, the Subsidiaries or the Joint
Ventures, provided that such counsel shall state that they believe that both
           --------                                                          
the Underwriters and they are justified in relying upon such opinions,
abstracts, reports, policies and certificates.  Such counsel shall also have
furnished to the Representatives a written statement, addressed to the
Underwriters and dated the Delivery Date, in form and substance satisfactory to
the Representatives to the effect that (i) such counsel has either acted as
counsel to the Company on a regular basis, or has acted as its General Counsel,
as the case may be (although the Company is also represented by other counsel as
to certain other matters), has acted as counsel to the Company in connection
with previous financing transactions and has acted as counsel to the Company in
connection with the preparation of the Registration Statement, and (ii) based on
the foregoing, no facts have come to the atten-

                                       26
<PAGE>
 
tion of such counsel which lead them to believe that (except for the financial
statements and other financial data included 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 statement therein not misleading, or that the
Prospectus 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 light of the circumstances under which they were made,
not misleading or (II) 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 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 Commission, 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.

          (e)  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

                                       27
<PAGE>
 
letter, and (iii) confirming in all material respects the conclusions and
findings set forth in the initial letter.

          (f)  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(g) 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 not misleading,
     and (B) since the Effective Date no event has occurred which should have
     been set forth in a supplement or amendment to the Registration Statement
     or the Prospectus.

          (g)  All the outstanding 12% Senior Notes with Contingent Interest due
1995, issued by the Company pursuant to the Note Purchase Agreement, dated
March 15, 1988, between Principal Mutual Life Insurance Company and the Company,
shall have been defeased;

          (h)  [All the outstanding shares of the Company's Series C Redeemable
Preferred Stock have been converted into the Company's common stock];

          (i)  None of the Company, any Subsidiary or any Joint Venture has
sustained since the date of the latest audited financial statements included or
incorporated by reference in the Prospectus (i) any loss or interference with
its business from fire, explosion, flood or other calamity, whether or not
covered by insurance, or from any labor dispute or court or governmental action,
order or decree or (ii) since such date there shall not have been any change in
the capital stock or long-term debt of the Company or any of its Subsidiaries or
any change, or

                                       28
<PAGE>
 
any development involving a prospective change, in or affecting the general
affairs, management, financial position, stockholders' equity or results of
operations of the Company and its Subsidiaries taken as a whole, the effect of
which, in any such case described in clause (i) or (ii), is, in the judgment of
the Representatives, so material and adverse as to 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.

          (j)  Subsequent to the execution and delivery of this Agreement (i) no
downgrading shall have occurred in the rating accorded the Company's debt
securities or preferred stock 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 possible
negative implications, its rating of any of the Company's debt securities or
preferred stock.

          (k)  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

of a national emergency or war by the United States 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 deliv-

                                       29
<PAGE>
 
ery 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, or any action in
respect thereof (including, but not limited to, any loss, claim, damage,
liability or 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 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 as
such expenses are incurred; 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

                                       30
<PAGE>
 
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, unless such failure resulted from non-compliance by the Company with
Section 5(c).  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
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, each of its officers who
signed the Registration Statement 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, or any action in respect thereof,
to which the Company or any such director, officer 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 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 that Underwriter
specifically for inclusion therein, and shall reimburse the Company and

                                       31
<PAGE>
 
any such director, officer or controlling person for any legal or other expenses
reasonably incurred by the Company or any such director, officer or controlling
person in connection with investigating or defending or preparing to defend
against any such loss, claim, damage, liability or action as such expenses are
incurred.  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.

          (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; 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 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 Representatives shall have the right to employ counsel to represent jointly
the Representatives and those other Underwriters 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 Underwriters against the
Company under this Section 8 if, in the reasonable judgment of the
Representatives, it is advisable for the Representatives and those Underwriters
and controlling persons to be jointly represented by

                                       32
<PAGE>
 
separate counsel, and in that event the fees and expenses of such separate
counsel shall be paid by the Company.

          (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, on the one hand, and the total underwriting
discounts and commissions received by the Underwriters with respect to the Notes
purchased under this Agreement, on the other hand, bear to the total gross
proceeds from the offering of the Notes under this Agreement, in each case as
set forth in the table on the cover page of the Prospectus.  The relative fault
shall be determined by reference to whether the untrue or alleged untrue state-
ment 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 treat-

                                       33
<PAGE>
 
ed 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 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.
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 fraud-
ulent 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; pro-
                                              ----

                                       34
<PAGE>
 
vided, 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 9.09% of the aggregate principal amount of the
Notes to be purchased on the Delivery Date, and any remaining non-defaulting
Underwriter shall not be obligated to purchase more than 110% of the principal
amount of the Notes which it agreed to purchase on the Delivery Date pursuant to
the terms of Section 2.  If the foregoing maximums are 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

                                       35
<PAGE>
 
prior to delivery of and payment for the Notes if, prior to that time, any of
the events described in Section 7(h) or 7(i) 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 Company
               ---------------------------------------                     
shall fail to tender the Notes for delivery to the Underwriters or (b) the
Underwriters shall decline to purchase the Notes for any reason permitted
under this Agreement (including the termination of this Agreement pursuant to
Section 10), the Company shall reimburse the Underwriters for the fees and
expenses of their counsel and for such other 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.  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,
          telex or facsimile transmission to Lehman Brothers Inc., Three World
          Financial Center, New York, New York 10285, Attention:  Syndicate
          Departments (Fax: 212-528-8822);

               (b) if to the Company, shall be delivered or sent by mail, telex
          or facsimile transmission to the address of the Company set forth in
          the Registration Statement, Attention:  General Counsel;

provided, however, that any notice to an Underwriter pursuant to Section 8(c)
- --------  -------                                                            
shall be delivered or sent by mail, telex or facsimile transmission to such
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

                                       36
<PAGE>
 
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
behalf of the Underwriters by Lehman Brothers Inc. on behalf of the
Representatives.

          13.  Persons Entitled to Benefit of Agreement.  This Agreement shall
               ----------------------------------------                       
inure to the benefit of and be binding upon the Underwriters, the Company, and
their respective successors.  This Agreement and the terms and provisions hereof
are for the sole benefit of only those persons, except that (a) the
representations, 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, if any, who control any Underwriter within the meaning of Section 15
of the 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 of the Company, officers of the Company who have signed the
Registration Statement and any person controlling the Company within the meaning
of Section 15 of the Securities Act.  Nothing in this Agreement is intended or
shall be construed to give any person, 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,
Inc. is open for trading.

          16.  Governing Law.  THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED
               -------------                                                    
IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

counterparts and, if executed in more than one counterpart, the executed
counterparts shall each be deemed to be an original but all such counterparts
shall together constitute one and the same instrument.

          18.  Headings.  The headings herein are inserted for convenience of
               --------

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

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

after such record date as the Record Expiration Date with respect thereto,

any case where notice to Holders is given by mail, neither the failure to mail
such notice, nor any defect in any notice so mailed, to any particular Holder
shall affect the sufficiency of such notice with respect to other Holders.
Where 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.

shall receive an Offer to Purchase from the Company prior to the related
Purchase Date, and may elect to have such 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,

particular date shall equal 100% of the principal amount payable in respect of
this Security at the Stated Maturity hereof. Upon payment of (i) the Default
Amount so declared due and payable and any overdue installment of interest in
respect of this Security, (ii) any overdue principal or premium payable on
redemption or repurchase of this Security as provided on the face hereof, any
interest on any overdue Default Amount, principal, premium or interest in
respect of this

Security (to the extent that the payment of such interest shall be legally
enforceable), all of the Company's obligations in respect of the payment of the
principal of and any premium and interest on this Security shall terminate.

     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 at Stated Maturity of the Securities at
the time Outstanding. The Indenture also contains provisions permitting the
Holders of specified percentages in aggregate principal amount at Stated
Maturity 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, 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 which shall not ad-
versely affect in any material aspect 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 at Stated Maturity of the Securities at the time Outstanding shall have
made written request to the Trustee to institute proceedings in respect of
such Event

                                      -52-
<PAGE>
 
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 at Stated Maturity of Securities at the time Outstanding a direction
inconsistent with such request, and shall have failed to institute any such
proceeding, for 30 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, 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 will 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 autho-

                                      -53-
<PAGE>
 
rized 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 in whose name this Security is registered as the owner hereof for
all purposes, whether or not this Security be overdue and neither the Company,
the Trustee nor any such agent shall be affected by notice to the contrary.

year of twelve 30-day months.

     All terms used in this Security which 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.

provided in Article Twelve of this Indenture.

Section 302.  Denominations.
              ------------- 

     The Securities shall be issuable only in registered form without coupons

     The Securities shall be executed on behalf of the Company by its Chairman
of the Board, its President or one of its Vice Presidents, under its corporate
seal reproduced thereon attested by its Secretary or one of its Assistant
Secretaries.  The signature of any of these officers on the Securities may be

     Securities bearing the manual or facsimile signatures of individuals who
were at any time the proper officers of the Company shall bind the Company,
notwithstanding that such individuals or any of them have ceased to hold such
offices prior to the authentication and delivery of such Securities or did not
hold such offices at the date of such Securities.

     At any time and from time to time after the execution and delivery of this
Indenture, the Company may deliver Securities executed by the Company to the
Trustee for authentication, together with a Company Order for the authentication
and delivery of such Securities; and the Trustee in accordance with such Company
Order shall authenticate and deliver such Securities as in this Indenture
provided and not otherwise.

     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

                                      -58-
<PAGE>
 
such certificate upon any Security shall be conclusive evidence, and the only
evidence, that such Security has been duly authenticated and delivered
hereunder.

Section 304.  Temporary Securities.
              -------------------- 

     Pending the preparation of definitive Securities, the Company may execute,
and upon Company Order the Trustee shall authenticate and deliver, temporary
Securities which 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 of this Indenture
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 of this Indenture being
herein sometimes collectively referred to as the "Security Register") in which,
subject to such reasonable regulations as it may prescribe, the Company

                                      -59-
<PAGE>
 
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 pursuant to Section 1002 of this Indenture 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 which 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

                                      -60-
<PAGE>
 
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 of this
Indenture, 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 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 of this Indenture 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.

                                      -61-
<PAGE>
 
     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 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 which 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 which 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,

                                      -62-
<PAGE>
 
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 when deposited to be held in trust for the
benefit of the Persons entitled to such Defaulted Interest as in this Clause
provided.  Thereupon the Trustee shall fix a Special Record Date for the payment
of such Defaulted Interest which 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 of this Indenture
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 mailed, 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

                                      -63-
<PAGE>
 
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 such Security
for the purpose of receiving payment of principal of (and premium, if any) and
(subject to Section 307 of this Indenture) 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 of this Indenture 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 which 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.

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 shall not be affected by any defect in or omission of such numbers.

     This Indenture shall cease to be of further effect (except as to any
surviving rights of registration of transfer or exchange of Securities herein
expressly provided for) and the Trustee, on demand of and at the expense of the
Company, shall execute proper instruments acknowledging satisfaction and
discharge of this Indenture, when

     (1)  either

     (A)  all Securities theretofore authenticated and delivered (other than (i)
Securities which have been destroyed, lost or stolen and which have been
replaced or paid as provided in Section 306 of this Indenture and (ii)
Securities for whose payment money has theretofore been deposited in trust or
segregated and held in trust by the Company and thereafter repaid to the Company

have been delivered to the Trustee for cancellation; or

     (B)  all such Securities not theretofore delivered to the Trustee for

          (i)   have become due and payable, or

          (iii) are to be called for redemption within one year under
irrevocable arrangements satisfactory to the Trustee for the giving of notice

     and the Company, in the case of (i), (ii) or (iii) above, has irrevocably
deposited or caused to be deposited with the Trustee as trust funds in trust
for the purpose an amount sufficient to pay and discharge the entire
indebtedness on such Securities not theretofore delivered to the Trustee for

and an Opinion of Counsel, each stating that all conditions precedent herein
provided for relating to the satisfaction and discharge of this Indenture have
been complied with.

Notwithstanding the satisfaction and discharge of this Indenture pursuant to

607 of this Indenture, the obligations of the Company to any Authenticating
Agent under Section 614 and, if money shall have been deposited with the Trustee
pursuant to subclause (B) of Clause (1) of this Section 401, the obligations of
the Trustee under Section 402 and the last paragraph of Section 1003 shall
survive.

Paying Agent (including the Company acting as its own Paying Agent) as the
Trustee may determine, to the Persons entitled thereto, of the principal (and
premium, if any) and interest for whose payment such money has been deposited
with the Trustee.  If the Trustee or Paying Agent is unable to apply any money
or U.S. Government Obligations in accordance with Section 401 by reason of any
legal proceeding or by reason of any order or judgment of any court or
governmental authority enjoining, restraining or otherwise prohibiting such
application, the Company's obligations under this Indenture and the Securities
shall be revived and reinstated as though no deposit had occurred pursuant to
Section 401 until such time as the Trustee or Paying Agent is permitted to apply
all such money or U.S. Government Obligations in accordance with the first
sentence of this Section 402; provided that if the Company has made any payment
                              --------

its obligations, the Company shall be subrogated to the rights of the Holders
of such Securities to receive such payment from the cash or U.S. Government
Obligations held by the Trustee or Paying Agent.

Section 502.   Acceleration of Maturity; Rescission and Annulment.
               -------------------------------------------------- 

     If an Event of Default (other than an Event of Default specified in Section
501(8) or (9) of this Indenture) occurs and is continuing, then and in every
such case the Trustee or the Holders of not less than 25

                                      -70-
<PAGE>
 
percent in principal amount at Stated Maturity of the Outstanding Securities may
declare the Default Amount of all the Securities to be due and payable
immediately by a notice in writing to the Company (and to the Trustee if given
by Holders), and upon any such declaration such Default Amount and any accrued
interest shall become immediately due and payable.  If an Event of Default
specified in Section 501(8) or (9) occurs, the Default Amount of and any accrued
interest on the Securities then Outstanding shall ipso facto become immediately
                                                  ---- -----                   
due and payable without any declaration or other Act on the part of the Trustee
or any Holder.

     Until and including __________, 1997, the "Default Amount" in respect of
any particular Security as of any particular date shall equal the Accreted Value
of the Security as of such date.  On and after __________, 1997, the Default
Amount in respect of any particular Security as of any particular date shall
equal 100% of the principal amount payable in respect of the Security at the
Stated Maturity thereof.

     At any time after such a declaration of acceleration has been made and
before a judgment or decree for payment of the money due has been obtained by
the Trustee as hereinafter in this Article Five provided, the Holders of a
majority in principal amount at Stated Maturity of the Outstanding Securities,
by written notice to the Company and the Trustee, may rescind and annul such
declaration and its consequences if

          (1)  the Company has paid or deposited with the Trustee a sum
sufficient to pay

               (A) all overdue interest on all Securities (without duplication
of any amount thereof paid or deposited pursuant to Clause (B) or (C) below),

               (B) the principal of (and premium, if any, on) any Securities
which have become due otherwise than by such declaration of acceleration
(including any Securities required to have been purchased on the Purchase
Date pursuant to an Offer to Purchase made by the Company) and, to the extent
that payment of such interest is lawful, interest thereon at the rate provided
by the

                                      -71-
<PAGE>
 
Securities (without duplication of any amount thereof paid or deposited pursuant
to Clause (A) above or Clause (C) below),

               (C) to the extent that payment of such interest is lawful,
interest upon overdue interest at the rate provided by the Securities (without
duplication of any amount thereof paid or deposited pursuant to Clause (A) or
(B) above), and

               (D) all sums paid or advanced by the Trustee hereunder and the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel;

     and

          (2)  all Events of Default, other than the nonpayment of the
principal of Securities which have become due solely by such declaration of
acceleration, have been cured or waived as provided in Section 513 of this
Indenture.

No such rescission shall affect any subsequent default or impair any right
consequent thereon.

Section 503.   Collection of Indebtedness and Suits for Enforcement by Trustee.
               --------------------------------------------------------------- 

     The Company covenants that if

          (1)  default is made in the payment of any interest on any Security
when such interest becomes due and payable and such default continues for a
period of 30 days, or

          (2)  default is made in the payment of the principal of (or premium,
if any, on) any Security at the Maturity thereof or, with respect to any
Security required to have been purchased pursuant to an Offer to Purchase made
by the Company, at the Purchase Date thereof,

the Company shall, upon demand of the Trustee, pay to it, for the benefit of the
Holders of such Securities, the

                                      -72-
<PAGE>
 
whole amount then due and payable on such Securities for principal (and premium,
if any) and interest, and, to the extent that payment of such interest shall be
legally enforceable, interest on any overdue principal (and premium, if any) 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.

Section 504.   Trustee May File Proofs of Claim.
               -------------------------------- 

     In case of any judicial proceeding relative to the Company (or any other
obligor upon the Securities), its Property or assets or its creditors, the
Trustee (irrespective of whether the principal of the Securities then shall be
due and payable as therein expressed or by declaration or otherwise and
irrespective of whether the Trustee has made any demand on the Company for the
payment of overdue principal, premium, if any, or interest) shall be entitled
and empowered, by intervention in such proceeding or otherwise, to file such
proofs of claim and other papers or documents and to take any and all actions

                                      -73-
<PAGE>
 
authorized under the Trust Indenture Act in order to have claims of the Holders
and the Trustee (including any claim for reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents 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 of this Indenture.  To the extent that payment of any such com-
pensation, 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 which 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.

     No provision of this Indenture shall be deemed to authorize the Trustee to
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
                                                           --------         
Trustee may, on behalf of the Holders, vote for the election of a trustee in
bankruptcy or similar official and be a member of a creditors or other similar
committee.

Section 505.   Trustee May Enforce Claims Without Possession of Securities.
               ------------------------------------------------------------ 

                                      -74-
<PAGE>
 
     All rights of action and claims under this Indenture or the Securities may
be prosecuted and enforced by the Trustee without the possession of any of the
Securities or the production thereof in any proceeding relating thereto, and any
such proceeding instituted by the Trustee shall be brought in its own name as
trustee of an express trust, and any recovery of judgment shall, after provision
for the payment of the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel, be for the ratable benefit of
the Holders of the Securities in respect of which such judgment has been
recovered.

Section 506.  Application of Money Collected.
              ------------------------------ 

     Any money collected by the Trustee pursuant to this Article Five shall be
applied in the following order, at the date or dates fixed by the Trustee and,
in case of the distribution of such money on account of principal (or premium,
if any) or interest, upon presentation of the Securities and the notation
thereon of the payment if only partially paid and upon surrender thereof if
fully paid:

          FIRST:    To the payment of all amounts due the Trustee under Section
607; and

          SECOND:   To the payment of the amounts then due and unpaid for
principal of (and premium, if any) and interest on the Securities in respect of
which or for the benefit of which such money has been collected, ratably,
without preference or priority of any kind, according to the amounts due and
payable on such Securities for principal (and premium, if any) and interest,
respectively; and

          THIRD:    To whosoever may be lawfully entitled thereto, the
remainder, if any.

Section 507.  Limitation on Suits.
              ------------------- 

     No Holder of any Security shall have any right to institute any proceeding,
judicial or otherwise, with respect to this Indenture, or for the appointment of
a

                                      -75-
<PAGE>
 
receiver or trustee, or for any other remedy hereunder, unless

          (1)  such Holder has previously given written notice to the Trustee of
a continuing Event of Default;

          (2)  the Holders of not less than 25 percent in principal amount at
Stated Maturity of the Outstanding Securities shall have made written request to
the Trustee to institute proceedings in respect of such Event of Default in its
own name as Trustee hereunder;

          (3)  such Holder or Holders have offered to the Trustee reasonable
indemnity against the costs, expenses and liabilities to be incurred in
compliance with such request;

          (4)  the Trustee for 60 days after its receipt of such notice, request
and offer of indemnity has failed to institute any such proceeding; and

          (5)  no direction inconsistent with such written request has been
given to the Trustee during such 60-day period by the Holders of a majority in
principal amount at Stated Maturity of the Outstanding Securities;

it being understood and intended that no one or more Holders shall have any
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,
or to obtain or to seek to obtain priority or preference over any other Holders
or to enforce any right under this Indenture, except in the manner herein
provided and for the equal and ratable benefit of all the Holders.

Section 508.   Unconditional Right of Holders to Receive Principal, Premium and
               ----------------------------------------------------------------
               Interest.
               -------- 

     Notwithstanding any other provision in this Indenture, the Holder of any
Security shall have the right, which is absolute and unconditional, to receive
payment of the principal of (and premium, if any) and (subject to Section 307 of
this Indenture) interest on such Security on the respective Stated Maturities
expressed in such

                                      -76-
<PAGE>
 
Security (or, in the case of redemption on the Redemption Date or in the case of
an Offer to Purchase made by the Company and accepted as to such Security, on
the Purchase Date) and to institute suit for the enforcement of any such
payment, and such rights shall not be impaired without the consent of such
Holder.

Section 509.  Restoration of Rights and Remedies.
              ---------------------------------- 

     If the Trustee or any Holder has instituted any proceeding to enforce any
right or remedy under this Indenture and such proceeding has been discontinued
or abandoned for any reason, or has been determined adversely to the Trustee or
to such Holder, then and in every such case, subject to any determination in
such proceeding, the Company, the Trustee and the Holders shall be restored
severally and respectively to their former positions hereunder and thereafter
all rights and remedies of the Trustee and the Holders shall continue as though
no such proceeding had been instituted.

Section 510.  Rights and Remedies Cumulative.
              ------------------------------ 

     Except as otherwise provided with respect to the replacement or payment of
mutilated, destroyed, lost or stolen Securities in the last paragraph of Section
306 of this Indenture, no right or remedy herein conferred upon or reserved to
the Trustee or to the Holders is intended to be exclusive of any other right or
remedy, and every right and remedy shall, to the extent permitted by law, be
cumulative and in addition to every other right and remedy given hereunder or
now or hereafter existing at law or in equity or otherwise.  The assertion or
employment of any right or remedy hereunder or otherwise shall not prevent the
concurrent assertion or employment of any other appropriate right or remedy.

Section 511.  Delay or Omission Not Waiver.
              ---------------------------- 

     No delay or omission of the Trustee or of any Holder of any Security to
exercise any right or remedy accruing upon any Event of Default shall impair any
such right or remedy or constitute a waiver of any such Event of Default or an
acquiescence therein.  Every right and remedy given by this Article Five or by
law to the Trustee or to

                                      -77-

the Holders may be exercised from time to time, and as often as may be deemed

Outstanding Securities shall have the right to direct the time, method and place
of conducting any proceeding for any remedy available to the Trustee or
exercising any trust or power conferred on the Trustee, provided that
                                                        --------     

          (1)  such direction shall not be in conflict with any rule of law or
with this Indenture, and

          (2)  the Trustee may take any other action deemed proper by the
Trustee which is not inconsistent with such direction.

Section 513.  Waiver Of Past Defaults.
              ----------------------- 

     The Holders of not less than a majority in principal amount at Stated
Maturity of the Outstanding Securities may on behalf of the Holders of all the
Securities waive any past default hereunder and its consequences, except a
default

          (1)  in the payment of the principal of (or premium, if any) or
interest on any Security (including any Security which is required to have been
purchased pursuant to an Offer to Purchase which has been made by the Company),
or

          (2)  in respect of a covenant or provision hereof which under Article
Nine cannot be modified or amended without the consent of the Holder of each
Outstanding Security affected.

     Upon any such waiver, such default shall cease to exist, and any Event of
Default arising therefrom shall be deemed to have been cured, for every purpose
of this Indenture; but no such waiver shall extend to any subsequent or other
default or impair any right consequent thereon.

Indenture, or in any suit against the Trustee for any action taken, suffered or
omitted by it as Trustee, a court may require any party litigant in such suit to
file an undertaking to pay the costs of such suit, and may assess costs against
any such party litigant, in the manner and to the extent provided in the Trust
Indenture Act; provided that neither this Section 514 nor the Trust Indenture
               --------                                                      
Act shall be deemed to authorize any court to require such an undertaking or to
make such an assessment in any suit instituted by the Company, in any suit
instituted by the Trustee or in any suit for the enforcement of the right to
require an Offer to Purchase to be made by the Company.

Section 515.  Waiver of Stay or Extension Laws.
              -------------------------------- 

     The Company covenants (to the extent that it may lawfully do so) that it
shall not at any time insist upon, or plead, or in any manner whatsoever claim
or take the benefit or advantage of, any usury, stay or extension law wherever
enacted, now or at any time hereafter in force, which may affect the covenants
or the performance of this Indenture; and the Company (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such law
and covenants that it shall not hinder, delay or impede the execution of any
power herein granted to the Trustee, but shall suffer and permit the execution

Section 601.  Certain Duties and Responsibilities.
              ----------------------------------- 

     (a)  The duties and responsibilities of the Trustee shall be as provided by
the Trust Indenture Act.  Whether or not therein expressly so provided, every
provision of this Indenture relating to the conduct or affecting the

                                      -79-
<PAGE>
 
liability of or affording protection to the Trustee shall be subject to the
provisions of this Section 601.

     (b)  Except during the continuance of an Event of Default,

          (1)  the Trustee undertakes to perform such duties and only such
duties as are specifically set forth in this Indenture, and no implied covenants
or obligations shall be read into this Indenture against the Trustee; and

          (2)  in the absence of bad faith on its part, the Trustee may
conclusively rely, as to the truth of the statements and the correctness of the
opinions expressed therein, upon certificates or opinions  furnished to the
Trustee and conforming to the requirements of this Indenture; but in the case
of any such certificates or opinions which by any provision hereof are
specifically required to be furnished to the Trustee, the Trustee shall be under
a duty to examine the same to determine whether or not they conform to the
requirements of this Indenture but need not confirm the accuracy of any calcu-
lations contained therein.

     (c)  In case an Event of Default has occurred and is continuing, the
Trustee shall exercise such of the rights and powers vested in it by this
Indenture, and use the same degree of care and skill in their exercise, as a
prudent man would exercise or use under the circumstances in the conduct of his
own affairs.

     (d)  No provision of this Indenture shall be construed to relieve the
Trustee from liability for its own negligent action, its own negligent failure
to act, or its own willful misconduct, except that
                                       ------     

          (1)  this Subsection shall not be construed to limit the effect of
Subsections (b) or (c) of this Section 601;

          (2)  the Trustee shall not be liable for any error of judgment made in
good faith by a Responsible Officer, unless it shall be proved that the Trustee
was negligent in ascertaining the pertinent facts; and

                                      -80-
<PAGE>
 
          (3) the Trustee shall not be liable with respect to any action taken
or omitted to be taken by it in good faith in accordance with the direction of
the Holders of a majority in principal amount at Stated Maturity of the
Outstanding Securities relating to the time, method and place of conducting any
proceeding for any remedy available to the Trustee, or exercising any trust or
power conferred upon the Trustee, under this Indenture.

     (e)  Notwithstanding the foregoing, no provision of this Indenture shall
require the Trustee to expend or risk its own funds or otherwise incur any
financial liability in the performance of any of its duties hereunder, or in
the exercise of any of its rights or powers, if it shall have reasonable grounds
for believing that repayment of such funds or adequate indemnity against such
risk or liability is not reasonably assured to it.

Section 602.  Notice of Defaults; Notice of Acceleration.
              ------------------------------------------ 

     Within 90 days after the occurrence of any Default or Event of Default, the
Trustee shall transmit by mail to all Holders, as their names and addresses
appear in the Security Register, notice of such Default or Event of Default
known to the Trustee, unless such Default or Event of Default shall have been
cured or waived; provided that, except in the case of a default in the payment
                 --------

payment required in connection with a Change of Control or Asset Disposition,
the Trustee shall be protected in withholding such notice if and so long as the
board of directors, the executive committee or a trust committee of directors or
Responsible Officers of the Trustee in good faith determine that the withhold-
ing of such notice is in the interest of the Holders; and provided further that
                                                          -------- -------     
in the case of any Default or Event of Default of the character specified in
Section 501(5) of this Indenture, no such notice to Holders shall be given until

Section 610.   Resignation and Removal; Appointment of Successor.
               -------------------------------------------------

acceptance of appointment by the successor Trustee in accordance with the
applicable requirements of Section 611 of this Indenture.
 
          (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 of this Indenture

Indenture 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

<PAGE>
 
to resign after written request therefor by the Company or by any such Holder,
or

               (3) the Trustee shall become incapable of acting or shall be
adjudged a bankrupt or insolvent or a receiver of the Trustee or of its property

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 at Stated Maturity 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 of
this Indenture, become the successor Trustee and supersede the successor
Trustee appointed by the Company.  If no successor Trustee shall have been so

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 appointment of a successor Trustee.

deliver to the Company and to the retiring Trustee an instrument accepting such
appointment, and thereupon the resignation or removal of the retiring Trustee
shall become effective and such 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 of this Indenture, 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 Trustee hereunder, subject,
nevertheless, to its Lien, if any, provided for in Section 607 of this
Indenture.  Upon request of any such successor Trustee, the Company shall
execute any and all instruments for more fully and certainly vesting in and
confirming to such successor Trustee all such rights, powers and trusts.

     No successor Trustee shall accept its appointment unless at the time of
such acceptance such successor Trustee shall be qualified and eligible under

     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

                                      -88-
<PAGE>
 
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 which 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 $100,000,000 and subject
to supervision or examina-

                                      -89-
<PAGE>
 
tion 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.

     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.

     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 which 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.

     If an appointment is made pursuant to this Section 614, the Securities may
have endorsed thereon, in lieu of the Trustee's certificate of authentication,
an alternative certificate of authentication in the following form:

     This is one of the Securities described in the within-mentioned Indenture.

provided that any such waiver shall not impair or affect the right of any Holder
- --------

     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

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 Compa-
ny 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

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

location of any such other office or agency.  The Company hereby initially

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

                                     -101-

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,

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

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.

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
                                                   --------

Company shall not be required to preserve any such right or franchise if the

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

     The Company shall cause all material properties used or useful in the

renewals, replacements, betterments and improvements thereof, all as in the

                                     -103-
<PAGE>
 
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 properties if
such discontinuance 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.

Section 1006.  Payment of Taxes and Other Claims.
               --------------------------------- 

     The Company shall pay or discharge or cause to be paid or discharged,
before the same shall become delinquent, (1) all taxes, assessments and
governmental charges levied or imposed upon the Company or any of its Re-
stricted 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 which, if unpaid, might by law become a Lien upon the
property of the Company or any of its Restricted Subsidiaries; provided that the
                                                               --------         
Company shall not be required to pay or discharge or cause to be paid or
discharged any such tax, assessment, charge or claim whose amount, applicability

required by GAAP.

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

     The Company shall, and shall cause its Restricted Subsidiaries to,
keep at all times all of their Properties which 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 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

                                     -104-
<PAGE>
 
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.

     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.

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 of this
Indenture.  Notwithstanding anything in the foregoing to the contrary, the
Company may not, and shall not permit any of its Restricted Subsidiaries to,
make an Asset Disposition of any interest in, or Property of, any of the [Coso
entities] other than for consideration consisting of cash.

          (c)  To the extent that any or all of the Net Cash Proceeds of any
Foreign Asset Disposition is 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 the applicable Restricted Subsidiary or the
applicable Eligible Joint Venture so long, but only so long, as the applicable
local law does not permit (or delays) repatriation to the United States.  The
Company shall take or cause the applicable Restricted Subsidiary or the appli-
cable 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, repa-
triation 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 date of such repatriation.  In addition,
if the Board of Directors determines, in good

                                     -119-
<PAGE>
 
faith, 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.  Not-
withstanding 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) of this Indenture, the Company may apply by such Net Cash Pro-
ceeds pursuant to such provision.

          (d)  If the aggregate principal amount of Securities tendered pursuant
to an Offer 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 provision of this Section 1015(d).  The
Company shall not be required to make an Offer for Securities 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 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 Offer with respect
thereto.

          (e)  The Company shall make an Offer by mailing to each Holder, within
30 days from the receipt of Excess Proceeds that cause the cumulated Excess
Proceeds to exceed $10 million, a written notice that shall specify the
purchase date, which shall not be less than 30 days nor more than 60 days after
the date of such notice (the "Purchase Date"), and that shall contain certain
information concerning the business of the Company that the Company believes in
good faith shall enable the Holders

                                     -120-
<PAGE>
 
to make an informed decision.  Holders that elect to have their Securities
purchased shall be required to surrender such Securities at least one Business
Day prior to the Purchase Date.  If at the expiration of the Offer period the
aggregate Accreted Value of Securities surrendered by Holders exceeds the amount
of such Excess Proceeds, the Company shall select the Securities to be purchased
on a pro rata basis.
     --- ----       

          [Add procedures]

          (f)  If the Company is prohibited by applicable law from making the
Offer or purchasing Securities thereunder, the Company need not make an Offer
for so long as such prohibition is in effect.

          (g)  The Company shall comply with all applicable tender offer rules,
including, without limitation, Rule 14e-1 under the Exchange Act, in connection
with an Offer.

Restricted Subsidiary or an Eligible Joint Venture, such Restricted
Subsidiary or such Eligible Joint Venture would be permitted to Incur such

market value of the property sold

Joint Venture to create, assume or otherwise cause or suffer to exist any

spite the Company's active efforts during such 18-month period to dispose of
such Ineligible Investments, the Company is unable to do so because of
regulatory difficulties or market conditions.

Section 1107.  Securities Payable on Redemption Date.
               ------------------------------------- 

     Notice of redemption having been given as aforesaid, the Securities so to
be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified, and from and after such date (unless the
Company shall default in the payment of the Redemption Price and any
applicable accrued and unpaid interest) such Securities shall not bear
interest and the Accreted Value of such Securities shall thereupon and
thereafter conclusively be deemed to be their Accreted Value determined on and
as of such Redemption Date. Upon surrender of any such Security for redemption
in accordance with said notice, such Security shall be paid by the Company at
the Redemption Price, together with any applicable accrued and unpaid interest
to the Redemption Date; provided that installments of interest whose Stated

of such Securities, or one or more Predecessor Securities, registered as such
at the close of business on the relevant Record Dates according to their terms
and the provisions of Section 307 of this Indenture.

     If any Security called for redemption in accordance with the election of
the Company made pursuant to Section 1101 shall not be so paid upon surrender
thereof for redemption, the principal (and premium, if any) shall, until paid,
bear interest or accrete from the Redemption Date at the rate or manner
provided by the Security.

                                     -129-

the Trustee shall authenticate and deliver to the Holder of such Security
without service charge, a new Security or Securities, of any authorized
denomination as requested by such Holder, in aggregate principal amount at
Stated Maturity equal to and in exchange for the unredeemed portion of the
principal amount at Stated Maturity of the Security so surrendered.

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

     The Company may elect, at its option at any time, to have Section 1202 or
Section 1203 of this Indenture applied to the Outstanding Securities (as a
whole and not in part) upon compliance with the conditions set forth below in
this Article Twelve. Any such election shall be evidenced by a Board
Resolution.

Section 1202.  Defeasance and Discharge.
               ------------------------ 

     Upon the Company's exercise of its option to have this Section applied to

deemed to have been discharged from its obligations with respect to such
Securities as provided in this Section 1202 on and after the date the
conditions set forth in Section 1204 of this Indenture are satisfied
(hereinafter called "Defeasance"). For this purpose, such Defeasance means
that the Company shall be deemed to have paid and discharged the entire
indebtedness represented by such Securities and to have satisfied all its
other obligations under such Securities and this Indenture insofar as such
Securities are concerned (and the Trustee, at the expense of the Company,
shall execute proper instruments acknowledging the same), subject to the
following which shall survive until otherwise terminated or discharged hereun-

Article Twelve.  Subject to compliance with this Article Twelve, the Company may
exercise its option to have this Section 1202 applied to the Outstanding
Securities (as a whole and not in part) notwithstanding the prior exercise of
its option to have Section 1203 of this Indenture applied to such Securities.

Section 1203.  Covenant Defeasance.
               ------------------- 

     Upon the Company's exercise of its option to have this Section applied to

Section 501(4) (with respect to Section 801(iii) or (iv)), Section 501(5)
(with respect to any of Sections 1005 through 1018, inclusive, and any such
covenants provided pursuant to Section 901(2)), Section 501(6) or Section
501(7) shall be deemed not to be or result in an Event of Default, in each
case with respect to such Securities as provided in this Section on and after
the date the conditions set forth in Section 1204 are satisfied (hereinafter
called "Covenant Defeasance"). For this purpose, such Covenant Defeasance
means that, with respect to such Securities, the Company may omit to comply

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

          The following shall be the conditions to the application of Section
1202 or Section 1203 of this Indenture to the Outstanding Securities:

               (1)  The Company shall irrevocably have deposited or caused to
be deposited with the Trustee (or another trustee which satisfies the
requirements contemplated by Section 609 and agrees to comply with the
provisions of this Article applicable to it) as trust funds in trust for the
purpose of making the following payments, specifically pledged as security for,
and dedicated solely to the benefits of the Holders of such Securities, (A)
money in an amount, or (B) U.S. Government Obligations that through the
scheduled payment of principal and interest in respect thereof in accordance
with their terms shall provide, not later than one day before the due date of
any payment, money in an amount, or (C) a combination thereof, in each case
sufficient, in the opinion of a nationally recognized firm of independent
public accountants expressed in a written certification thereof delivered to
the Trustee, to pay and discharge, and which shall be applied by the Trustee
(or any such other qualifying trustee) to pay and discharge, the principal of,
premium if any and any installment of accrued interest on such Securities on
the respective Stated Maturities thereof or, if the Company makes arrangements
satisfactory to the Trustee for the redemption of the Securities prior to their
Stated Maturity, on any earlier Redemption Date, in accordance with the terms of
this Indenture and such Securities.  As used herein, "U.S. Government
Obligations" means (x) securities that are (i) direct obligations of the United
States of America for the payment of which the full faith and credit of the
United States of America is pledged or (ii) obligations of a Person controlled
or supervised by and acting as an agency or instrumentality of the United States
of America the payment of which is unconditionally guaranteed as a full faith
and credit obligation by the United States of America, which, in either case
under claus-

                                     -132-
<PAGE>
 
es (i) or (ii) above, are not callable or redeemable at the option of the issuer
thereof, and (y) depositary receipts issued by a bank (as defined in Section
3(a)(2) of the Securities Act of 1933, as amended) as custodian with respect to
any U.S. Government Obligation which is specified in Clause (x) above and held
by such bank for the account of the holder of such depositary receipt, or with
respect to any specific payment of principal of or interest on any U.S.
Government Obligation which is so specified and held, provided that (except as
                                                      --------                
required by law) such custodian is not authorized to make any deduction from
the amount payable to the holder of such depositary receipt from any amount
received by the custodian in respect of the U.S. Government Obligation or the
specific payment of principal or interest of the U.S. Government Obligation
evidenced by such depositary receipt.

               (2)  In the event of an election to have Section 1202 of this
Indenture apply to the Outstanding Securities, the Company shall have delivered
to the Trustee an Opinion of Counsel stating that (A) the Company has received
from, or there has been published by, the Internal Revenue Service a ruling or
(B) since the date of this Indenture, there has been a change in the applicable
Federal income tax law, in either case (A) or (B) to the effect that, and based
thereon such opinion shall confirm that, the Holders of such Securities shall
not recognize gain or loss for Federal income tax purposes as a result of the
deposit, Defeasance and discharge to be effected with respect to such Securities
and shall be subject to Federal income tax on the same amount, in the same
manner and at the same times as would be the case if such deposit, Defeasance
and discharge were not to occur.

               (3)  In the event of an election to have Section 1203 of this
Indenture apply to the Outstanding Securities, the Company shall have delivered
to the Trustee an Opinion of Counsel to the effect that the Holders of such
Outstanding Securities shall not recognize gain or loss for Federal income tax
purposes as a result of the deposit and Covenant Defeasance to be effected with
respect to such Securities and shall be subject to Federal income tax on the
same amount, in the same manner and at the same times as would be the case if
such deposit and Covenant Defeasance were not to occur.

                                     -133-
<PAGE>
 
               (4)  No Default or Event of Default with respect to the
Outstanding Securities shall have occurred and be continuing at the time of
such deposit after giving effect thereto or, in the event of an election to
have Section 1202 of this Indenture apply to the Outstanding Securities, with
regard to any such event specified in Sections 501(8) and (9), at any time on
or prior to the 91st day after the date of such deposit (it being understood
that this condition shall not be deemed satisfied until after such 91st day).

               (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.

Section 1205.  Deposited Money and U.S. Government Obligations to Be Held in
               --------------------------------------------------------------
               Trust; Miscellaneous Provisions.
               ------------------------------- 

     Subject to the provisions of the last paragraph of Section 1003 of this
Indenture, 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 of this Indenture, the Trustee
and any such other

                                     -134-
<PAGE>
 
trustee are referred to collectively as the "Trustee") pursuant to Section 1204
of this Indenture 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 (including 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 of this Indenture or the principal and
interest received in respect thereof other than any such tax, fee or other
charge which 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 of this Indenture which, 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 which 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.
               ------------- 

     If the Trustee or the Paying Agent is unable to apply any money in
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 application, 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

                                     -135-
<PAGE>
 
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.

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


     This instrument may be executed in any number of counterparts, each of
which so executed shall be deemed to be an original, but all such counterparts
shall together constitute but one and the same instrument.
