OVERVIEW

Calpine Corporation ("Calpine"), a Delaware corporation, and subsidiaries
(collectively, the "Company") is engaged in the acquisition, development,
ownership and operation of power generation facilities and the sale of
electricity and steam, principally in the United States. The Company currently
has interests in 23 power plants and steam fields having an aggregate capacity
of 2,613 megawatts. The Company currently sells electricity and steam to 16
utility and other customers, principally under long-term power and steam sales
agreements, generated by power generation facilities located in six states and
Mexico. In addition, the Company has a 240 megawatt gas-fired power plant
currently under construction in Pasadena, Texas and an investment in a 169
megawatt gas-fired power plant currently under construction in Dighton,
Massachusetts. Since its inception in 1984, the Company has developed
substantial expertise in all aspects of electric power generation. The Company's
vertical integration has resulted in significant growth in recent years as the
Company has applied its extensive engineering, construction management,
operations, fuel management and financing capabilities to successfully implement
its acquisition and development program. The Company's strategy is to capitalize
on opportunities in the power market through an ongoing program to acquire,
develop, own and operate electric power generation facilities, as well as
marketing power and energy services to utilities and other end users.

The Company's net interest in power generation facilities has increased
from 297 megawatts in 1992 to 1,981 megawatts in 1997, including the facilities
currently under construction. Total assets have increased from $55.4 million as
of December 31, 1992 to $1.4 billion as of December 31, 1997. The Company's
revenue has increased to $276.3 million for 1997, representing a five-year
compound annual growth rate of 48% since 1992. The Company's EBITDA (as defined
herein) for 1997 increased to $172.6 million from $9.9 million in 1992,
representing a five-year compound annual growth rate of 77%.

THE MARKET

The power generation industry represents the third largest industry in the
United States, with an estimated end user market of over $200 billion of
electricity sales and 3,300 gigawatt hours of production in 1997. In response to
increasing customer demand for access to low-cost electricity and enhanced
services, new regulatory initiatives are currently being adopted or considered
at both state and federal levels to increase competition in the domestic power
generation industry. To date, such initiatives are under consideration at the

1
4

federal level and in approximately 45 states. In April 1996, the Federal Energy
Regulatory Commission ("FERC") adopted Order No. 888, opening wholesale power
sales to competition and providing for open and fair electric transmission
services by public utilities. In addition, the California Public Utilities
Commission ("CPUC") has issued an electric industry restructuring decision,
which originally provided for commencement of deregulation and implementation of
customer choice of electricity supplier by January 1, 1998, and is currently
scheduled to commence on April 1, 1998. The Company believes that industry
trends and such regulatory initiatives will lead to the transformation of the
existing market, which is largely characterized by electric utility monopolies
having old, inefficient high-cost generating facilities, selling to a captive
customer base, to a more competitive market where end users may purchase
electricity from a variety of suppliers, including non-utility generators, power
marketers, public utilities and others. The Company believes that these market
trends will create substantial opportunities for companies such as themselves
that are low cost power producers and have an integrated power services
capability which enables them to produce and sell energy to customers at
competitive rates.

The Company also believes that these market trends will result in the
disposition of power generation facilities by utilities, independent power
producers and industrial companies. Numerous utilities have announced their
intentions to sell their power generation facilities. Many independent producers
operating a limited number of power plants are seeking to dispose of such plants
in response to competitive pressures, and industrial companies are selling their
power plants to redeploy capital in their core businesses. The Company believes
that this consolidation will continue in the highly fragmented independent power
industry.

STRATEGY

The Company's objective is to become a leading power company by
capitalizing on emerging market opportunities in the domestic power markets. The
key elements of the Company's strategy are as follows:

Expand and diversify its domestic portfolio of power projects. In pursuing
its growth strategy, the Company intends to focus on opportunities where it is
able to capitalize on its extensive management and technical expertise to
implement a fully integrated approach to the acquisition, development and
operation of power generation facilities. This approach includes design,
engineering, procurement, finance, construction, management, fuel and resource
acquisition, operations and power marketing, which the Company believes provides
it with a competitive advantage.

Acquisition of power plants. The Company has significantly expanded and
diversified its project portfolio through the acquisition of power generation
facilities. Since 1993, the Company has completed transactions involving
thirteen gas-fired cogeneration facilities and two steam fields. As a result of
these transactions, the Company has more than quadrupled its aggregate power
generation capacity and substantially diversified its fuel mix during this
period. The Company intends to continue to pursue an active acquisition program.

Development of merchant power plants. The Company is also pursuing the
development of highly efficient, low-cost power plants that seek to take
advantage of inefficiencies in the electricity market. The Company intends to
sell all or a portion of the power generated by such merchant plants into the
competitive market through a portfolio of short, medium and long-term power
sales agreements. As part of Calpine's initial effort to develop merchant
plants, the Company has a 240 megawatt gas-fired power generation facility
currently under construction in Pasadena, Texas and a 169 megawatt gas-fired
power generation facility currently under construction in Dighton,
Massachusetts. The Company currently plans to develop additional low-cost,
gas-fired facilities in California, Texas, New England and other high-priced
power markets.

Enhance the performance and efficiency of existing power projects. The
Company continually seeks to maximize the power generation potential of its
operating assets and minimize its operating and maintenance expenses and fuel
costs. To date, the Company's power generation facilities have operated at an
average availability of approximately 97%. The Company believes that achieving
and maintaining a low-cost of production will be increasingly important to
compete effectively in the power generation market.

DESCRIPTION OF FACILITIES

The Company currently has interests in 23 power generation facilities and
steam fields with a current aggregate capacity of approximately 2,613 megawatts,
consisting of fifteen gas-fired power plants with a total capacity of 2,127
megawatts, three geothermal power generation facilities (which include a steam
field and a power plant) with a total capacity of 67 megawatts and five
geothermal steam fields that supply utility power plants with a total current
capacity of approximately 419 megawatts. In addition, the Company has a 240
megawatt gas-fired power generation facility under construction in Pasadena,
Texas, and an investment in a 169 megawatt gas-fired power generation facility
currently under construction in Dighton, Massachusetts. Each of the power
generation facilities currently in operation produces electricity for sale to a
utility or other thirdparty end user. Thermal energy produced by the gas-fired
cogeneration facilities is sold to governmental and industrial users, and steam
produced by the geothermal steam fields is sold to utility-owned-power plants.

The gas-fired and geothermal power generation projects in which the Company
has an interest produce electricity, thermal energy and steam that are typically
sold pursuant to long-term, take and pay power or steam sales agreements
generally having original terms of 20 or 30 years. Revenue from a power sales
agreement usually consists of two components: energy payments and capacity
payments. Energy payments are based on a power plant's net electrical output
where payment rates may be determined by a schedule of prices covering a fixed
number of years under the power sales agreement, after which payment rates are
usually indexed to the fuel costs of the contracting utility or to general
inflation indices. Capacity payments are based on a power plant's net electrical
output and/or its available capacity. Energy payments are made for each
kilowatt-hour of energy delivered, while capacity payments, under certain
circumstances, are made whether or not any electricity is delivered. The Company
is paid for steam supplied by its steam fields on the basis of the amount of
electrical energy produced by, or steam delivered to, the contracting utility's
power plants.

The Company currently provides operating and maintenance services for 16 of
the 23 power plants and steam fields in which the Company has an interest. Such
services include the operation of power plants, geothermal steam fields, wells
and well pumps, gathering systems and gas pipelines. The Company also supervises
maintenance, materials, purchasing and inventory control, manages cash flow,
trains staff and prepares operating and maintenance manuals for each power
generation facility. As a facility develops an operating history, the Company
analyzes its operation and may modify or upgrade equipment or adjust operating
procedures or maintenance measures to enhance the facility's reliability or
profitability. These services are performed under the terms of an operating and
maintenance agreement pursuant to which the Company is generally reimbursed for
certain costs, is paid an annual operating fee and may also be paid an incentive
fee based on the performance of the facility. The fees payable to the Company
are generally subordinated to any lease payments or debt service obligations of
non-recourse financing for the project.

In order to provide fuel for the gas-fired power generation facilities in
which the Company has an interest, natural gas reserves are acquired or natural
gas is purchased from third parties under supply agreements. The Company
attempts to structure a gas-fired power facility's fuel supply agreement so that
gas costs have a direct relationship to the fuel component of revenue energy
payments.

Certain power generation facilities in which the Company has an interest
have been financed primarily with non-recourse project financing that is
structured to be serviced out of the cash flows derived from the sale of
electricity, thermal energy and/or steam produced by such facilities and
provides that the obligations to pay interest and principal on the loans are
secured almost solely by the capital stock or partnership interests, physical
assets, contracts and/or cash flow attributable to the entities that own the
facilities. The lenders under non-recourse project financing generally have no
recourse for repayment against the Company or any assets of the Company or any
other entity other than foreclosure on pledges of stock or partnership interests
and the assets attributable to the entities that own the facilities.

Substantially all of the power generation facilities in which the Company
has an interest are located on sites which are leased on a long-term basis. The
Company currently holds interests in geothermal leaseholds in The Geysers that
produce steam for sale under steam sales agreements and for use in producing
electricity from its wholly-owned geothermal power generation facilities.

6

The continued operation of power generation facilities and steam fields
involves many risks, including the breakdown or failure of power generation
equipment, transmission lines, pipelines or other equipment or processes and
performance below expected levels of output or efficiency. To date, the
Company's power plants have operated at an average availability of 97%. Although
from time to time the Company's power generation facilities have experienced
certain equipment breakdowns or failures, such breakdowns or failures have not
had a material adverse effect on the operation of such facilities or on the
Company's results of operations. Although the Company's facilities contain
certain redundancies and back-up mechanisms, there can be no assurance that any
such breakdown or failure would not prevent the affected facility or steam field
from performing under applicable power and/or steam sales agreements. In
addition, although insurance is maintained to protect against certain of these
operating risks, the proceeds of such insurance may not be adequate to cover
lost revenue or increased expenses, and, as a result, the entity owning such
power generation facility or steam field may be unable to service principal and
interest payments under its financing obligations and may operate at a loss. A
default under such a financing obligation could result in the Company losing its
interest in such power generation facility or steam field.

Insurance coverage for each power generation facility includes commercial
general liability, workers' compensation, employer's liability and property
damage coverage, which generally contains business interruption insurance
covering debt service and continuing expenses for a period ranging from 12 to 18
months.

The Company believes that each of the currently operating power generation
facilities in which the Company has an interest is exempt from financial and
rate regulation as a public utility under federal and state laws.

Texas City and Clear Lake Power Plants

On June 23, 1997, the Company completed the acquisition of a 50% equity
interest in the Texas City and the Clear Lake Cogeneration facilities for a
total purchase price of $35.4 million. The Company acquired its 50% interest in
these plants through the acquisition of 50% of the capital stock of Enron
Dominion Cogen Corp., subsequently renamed Texas Cogeneration Company ("TCC")
from Enron Power Corp., which is a wholly-owned subsidiary of Enron Corp.
("Enron"). The other 50% shareholder in TCC is Dominion Cogen, Inc., a
wholly-owned subsidiary of Dominion Energy, Inc. which in turn is a wholly-owned
subsidiary of Dominion Resources, Inc., which is the parent company of VEPCO. In
addition to the purchase of 50% of the stock of TCC, the Company, through its
wholly-owned subsidiary, Calpine Finance Company ("CFC"), purchased from the
existing lenders the $155.6 million of outstanding non-recourse project
financing incurred by TCC in connection with the Texas City Power Plant
(approximately $53.0 million) and the Clear Lake Power Plant (approximately
$102.6 million). The acquisition of the capital stock of TCC and the purchase of

the outstanding debt from the existing lenders were financed with approximately
$125.0 million of non-recourse project financing provided by The Bank of Nova
Scotia and $70.0 million of equity provided by the Company. The non-recourse
project financing matures on June 22, 1998 and bears interest at London
Interbank Offered Rate ("LIBOR") plus an agreed margin, currently 7.2% per
annum. The Company currently expects to refinance this non-recourse project
financing before June 22, 1998.

Texas City Power Plant -- The Texas City Power Plant is a 450 megawatt
gas-fired cogeneration facility located in Texas City, Texas. The Texas City
Power Plant includes three Westinghouse W-501D5 combustion turbines, three
Econotherm heat recovery steam generators and one Hitachi steam turbine. The
Texas City Power Plant commenced commercial operation in June 1987. In 1997, the
Texas City Power Plant operated at an average availability of 92.9%.

Electricity generated by the Texas City Power Plant is sold under two
separate long-term agreements to (i) TUEC under a power sales agreement
terminating on September 30, 2002 and (ii) Union Carbide Company ("UCC") under a
steam and electricity services agreement terminating on June 30, 1999. Each
agreement contains payment provisions for capacity and electric energy payments.

Under a steam and electricity services agreement expiring October 19, 2003,
the Texas City Power Plant will supply UCC with 300,000 lbs/hr of steam on a
monthly average basis, with the required supply of steam not exceeding 600,000
lbs/hr at any given time. It is necessary for the Texas City Power Plant to
provide a certain amount of thermal energy to a host facility in order to
maintain its qualifying facility ("QF") status.

Natural gas requirements for the Texas City Power Plant are allocated
between UCC, DEI Texas, Inc. ("DEI"), an affiliate of Dominion Cogen Inc., and
Enron Capital & Trade Resources Corporation ("ECT") pursuant to a contractual
arrangement. UCC and DEI currently provide approximately 25% and 56%,
respectively, of the fuel requirements of the Texas City Power Plant. The three
fuel contracts are effective through June 30, 1999. Under the fuel contracts,
approximately 19% of the total fuel requirements of the Texas City Power Plant
is supplied at spot market prices. The remainder is purchased at fixed rates set
forth in the contracts.

The Texas City Power Plant is operated and maintained by the Company under
a one-year operating and maintenance agreement with automatic renewal
provisions, pursuant to which the Company is reimbursed for certain costs and is
entitled to a fixed annual fee and an incentive payment based on project
performance.

The Texas City Power Plant is located on approximately 9 acres of land in
Texas City, Texas.

During 1997, the Texas City Power Plant generated approximately
2,704,481,000 kilowatt-hours of electric energy for sale to TUEC and UCC and
approximately $197.6 million of revenue.

Clear Lake Power Plant commenced commercial operation in December 1984. In 1997,
the Clear Lake Power Plant operated at an average availability of 97.4%.

Electricity generated by the Clear Lake Power Plant is sold under three
separate long-term agreements to (i) TNP under an original 20-year power sales
agreement terminating in 2004, (ii) HL&P under an original 10- year power sales
agreement terminating in 2005, and (iii) HCCG under an original 10-year power
sales agreement terminating in 2004. Each power sales agreement contains payment
provisions for capacity and energy payments.

Under a steam purchase and sale agreement expiring August 31, 2004, the
Clear Lake Power Plant will supply up to 900,000 lbs/hr of steam to HCCG. It is
necessary for the Clear Lake Power Plant to provide a certain amount of thermal
energy to a host facility in order to maintain its QF status.

The natural gas for the Clear Lake Power Plant is purchased primarily from
TCC, which receives its fuel from ECT. In addition, the facility burns hydrogen
provided by HCCG, amounting to about 5% of the Clear Lake Power Plant's total
fuel requirements.

Electrical energy generated by the Sumas Power Plant is sold to Puget Sound
Power & Light Company ("Puget") under the terms of a 20-year power sales
agreement terminating in 2013. Under the power sales agreement, Puget has agreed
to purchase an annual average of 123 megawatts of electrical energy.

The power sales agreement provides for the sale of electrical energy at a
total price equal to the sum of (i) a fixed price component and (ii) a variable
price component multiplied by an escalation factor for the year in which the
energy is delivered. The schedule of annual fixed average energy prices
(expressed in cents per kilowatt hour) in effect through 2013 under the Sumas
power sales agreement is as follows:



FIXED FIXED FIXED
ENERGY ENERGY ENERGY
YEAR PRICE YEAR PRICE YEAR PRICE
---- ------ ---- ------ ---- ------

1998................. 3.64c 2004........... 6.33c 2009........... 5.40c
1999................. 3.98c 2005........... 6.45c 2010........... 5.49c
2000................. 4.23c 2006........... 6.57c 2011........... 5.58c
2001................. 6.23c 2007........... 5.23c 2012........... 5.58c
2002................. 6.11c 2008........... 5.31c 2013........... 5.58c
2003................. 6.22c


The variable price component is set according to a scheduled rate set forth
in the agreement, which in 1997 was 1.02c per kilowatt hour, and escalates
annually by a factor equal to the U.S. Gross National Product Implicit Price
Deflator. For 1997, the average price paid by Puget under the power sales
agreement was 4.40c per kilowatt hour. Pursuant to the power sales agreement,
Puget may displace the production of the Sumas Power Plant when the cost of
Puget's replacement power is less than the Sumas Power Plant's incremental power
generation costs. Thirty-five percent of the savings to Puget under this
displacement provision are shared with the Sumas Power Plant.

In addition to the sale of electricity to Puget, pursuant to a long-term
steam supply and dry kiln lease agreement, the Sumas Power Plant produces and
sells approximately 23,000 lbs per hour of low pressure steam to an adjacent
lumber-drying facility owned by Sumas, which has been leased to and is operated
by Socco, Inc. ("Socco"), an SEI affiliate. It is necessary to continue to
operate the dry kiln facility in order to maintain the Sumas Power Plant's QF
status.

In connection with the development of the Sumas Power Plant, Canadian
natural gas reserves located primarily in northeastern British Columbia, Canada
were acquired by Sumas through its wholly owned subsidiary, ENCO. The gas
reserves owned by ENCO totaled approximately 105 billion cubic feet as of
January 1, 1998. Firm transportation is contracted for on the Westcoast Energy
Inc. pipeline. Gas is delivered to Huntington, British Columbia, where it is
transferred into Sumas' own pipeline for transportation to the plant. ENCO is
currently supplying approximately 12,900 mmbtu per day to the Sumas Power Plant.
The remaining 12,100 mmbtu per day requirement is being supplied under a
one-year contract with West Coast Gas Services, Inc.

provides for a firm capacity payment of $184 per kilowatt year for 111 megawatts
for the term of the agreement so long as the King City Power Plant delivers 80%
of the firm capacity during designated periods of the year. Additional capacity
payments are received for as-delivered capacity in excess of 111 megawatts
delivered during peak and partial peak hours. The as-delivered capacity price is
$188 per kilowatt year for 1998. Thereafter, the payment for as-delivered
capacity will be the greater of $188 per kilowatt year or PG&E's then current
as-delivered capacity rate. From January 1, 1998 through April 30, 1998,
payments for electrical energy produced are based on 100% of the interim
short-run avoided cost ("SRAC"), which is calculated pursuant to the methodology
approved by the CPUC on December 9, 1996. Following the commencement of
operations of the independent power exchange (currently scheduled for April 1,
1998), payments for electrical energy produced will be based on the energy
clearing price of the independent power exchange (referred to herein as the
"Power Exchange Price"). From May 1, 1998 through December 31, 1998, payments
for electrical energy are based on 80% of SRAC (or the Power Exchange Price,
when available) and 20% at fixed prices. The fixed average energy price in
effect for 1998 under the King City power sales agreement is 13.14c per kilowatt
hour. Thereafter, PG&E is required to pay for electrical energy actually
delivered at SRAC (or the Power Exchange Price, when available). During 1997,
SRAC averaged approximately 2.94c per kilowatt hour.

Through April 28, 1999, the power sales agreement allows for dispatchable
operation, which gives PG&E the right to curtail the number of hours per year
that the King City Power Plant operates. PG&E has an option to extend its
curtailment rights for two additional one-year terms. If PG&E exercises the
curtailment extension option, it will be required to pay an additional 0.7c per
kilowatt hour for all energy delivered from the King City Power Plant.

In addition to the sale of electricity to PG&E, the King City Power Plant
produces and sells thermal energy to a thermal host, Basic Vegetable Products,
Inc. ("BVP"), an affiliate of BAF, under a long-term contract coterminous with
the power sales agreement. It is necessary to continue to operate the host
facility in order to maintain the King City Power Plant's QF status. The BVP
facility was built in 1957 and processes between 30% and 40% of the dehydrated
onion and garlic production in the United States.

Natural gas for the King City Power Plant is supplied by Calpine Fuels
Corporation ("Calpine Fuels"), a wholly-owned subsidiary of the Company, which
purchases gas under short-term gas supply agreements.

15
18

Natural gas is transported under a firm transportation agreement, expiring on
March 1, 1999, via a 38-mile pipeline owned and operated by PG&E.

Fee title to the premises is owned by Basic American, Inc., which has
leased the premises to an affiliate of BAF for a term equivalent to the term of
the power sales agreement for the King City Power Plant. The Company is
subleasing the premises, together with certain easements, from such affiliate of
BAF pursuant to a ground sublease for approximately 15 acres.

During 1997, the King City Power Plant generated approximately 424,879,000
kilowatt hours of electrical energy and approximately $45.8 million of total

under this agreement by 984 hours.

The Aidlin Power Plant is operated and maintained by the Company under an
operating and maintenance agreement pursuant to which the Company is reimbursed
for certain costs and is entitled to an incentive payment based on project
performance. This agreement expires on December 31, 1999.

The Aidlin Power Plant is located on 713.8 acres of land located in The
Geysers, which is leased by GEP from a private landowner. The lease will remain
in force so long as geothermal steam is produced in commercial quantities.

During 1997, the Aidlin Power Plant generated approximately 172,959,000
kilowatt hours of electrical energy and revenue of $25.0 million. In 1997, the
Company recognized revenue of approximately $455,000 as a result of the
Company's 5% ownership interest and $3.0 million for services performed under
the operating and maintenance agreement.

STEAM FIELDS

Thermal Power Company Steam Fields

The Company acquired Thermal Power Company ("TPC") on September 9, 1994 for
a purchase price of $66.5 million. TPC owns a 25% undivided interest in certain
geothermal steam fields located at The Geysers in northern California (the
"Thermal Power Company Steam Fields"). Union Oil Company of California ("Union
Oil") and NEC own the remaining 75% interest in the steam fields and operates
and maintains the steam fields. The Thermal Power Company Steam Fields include
the leasehold rights to 13,908 acres of steam fields which supply steam to 12
PG&E power plants located in The Geysers and include 238 production wells, 18
injection wells and 55 miles of steam-transporting pipeline. The 12 plants have
a mechanical capacity of 872 megawatts and currently have the capability to
operate at over 560 megawatts. The steam fields commenced commercial operation
in 1960.

The Thermal Power Company Steam Fields produce steam for sale to PG&E under
a long-term steam sales agreement. Under this steam sales agreement, the Company
is paid on the basis of the amount of electricity produced by the power plants
to which steam is supplied. PG&E is obligated to use its best efforts to operate
its power plants to maintain monthly and annual steam field capacity. PG&E is
contractually

22
25

obligated to operate all of the power plants at a minimum of 40% of the field
capacity during any given year, and at 25% of the field capacity in any given
month. The price paid for steam under the steam sales agreement is determined
according to a formula that consists of the average of three indices multiplied
by a fixed price of 1.65c per kilowatt hour. The indices used are the Producer
Price Index for Crude Petroleum, the Producer Price Index for Natural Gas and
the Consumer Price Index ("CPI"). The price of steam under the steam sales
agreement in 1997 was 1.92c per kilowatt hour. The price for 1998 is estimated
to be 1.95c per kilowatt hour. In addition, TPC receives a monthly fee for
effluent disposal and maintenance. During 1997, such monthly fee was $152,000.

In March 1996, TPC, NEC and Union Oil entered into an alternative pricing
agreement with PG&E for any steam produced in excess of 40% of average field
capacity as defined in the steam sales contract. The alternative pricing
agreement is effective through December 31, 2000. Under the alternative pricing
agreement, PG&E has the option to purchase a portion of the steam that PG&E
would likely curtail under the existing steam sales agreement. The price for
this portion of steam will be set by TPC, NEC and Union Oil with the intent that
it be at competitive market prices. TPC, NEC and Union Oil will solely determine
the price and duration of these alternative prices.

The steam sales agreement with PG&E also provides for offset payments,
which constitute a remedy for insufficient steam. The offset payments are
calculated based upon a fixed amortization schedule for all power plants, which
may be adjusted for future capital expenditures, and upon the steam fields'
capacity in megawatts. In accordance with the steam sales agreement, TPC makes
offset payments at a reduced rate until total offsets calculated since July 1,
1991 equal $15.0 million. Accordingly, TPC's share of offsets in 1997 was
$582,000. In approximately 2001, when total offsets may exceed $15.0 million, in
accordance with the agreement TPC's share of offset payments to PG&E would be
approximately 3 1/2 times their current rate (as calculated at the current steam
field capacity).

The steam sales agreement with PG&E terminates two years after the closing
of the last operating power plant. In addition, PG&E may terminate the contract
earlier with a one-year written notice. If PG&E terminates in accordance with
the steam sales agreement, TPC will provide capacity maintenance services for
five years after the termination date, and will retain a right of first refusal
to purchase the PG&E facilities at PG&E's unamortized cost. Alternatively, TPC
may terminate the agreement with a two-year written notice to PG&E. If TPC
terminates, PG&E has the right to take assignment of the Thermal Power Company
Steam Fields' facilities on the date of termination. In that case, TPC would
continue to pay offset payments for three years following the date of
termination. Under the steam sales agreement, PG&E may retire older power plants
upon a minimum of six-months' notice. TPC is unable to predict PG&E's schedule
for the retirement of such power plants, which may change from time to time. If
steam is abandoned (i.e., cannot be transported to the remaining plants), the
abandoned steam may be delivered for use to other PG&E power plants, subject to
existing contract conditions, or to other customers upon closure of a PG&E power
plant.

The Thermal Power Company Steam Fields currently supply steam sufficient to
operate the PG&E power plants at approximately 60% of their combined mechanical
capacity. This percentage reflects a decline in productivity since the
commencement of operations. While it is not possible to accurately predict
long-term steam field productivity, the Company has estimated that the current
annual rate of decline in steam field productivity of the Thermal Power Company
Steam Fields is approximately 8%. The Company expects steam field productivity
to continue to decline in the future. The City of Santa Rosa, California, has
selected a proposal jointly submitted by the Company and Union Oil to construct
a water injection project utilizing tertiary treated wastewater from the City of
Santa Rosa. This project is expected to partially offset the anticipated rate of
decline in steam field productivity. The implementation of this project, if
completed, is subject to certain conditions, including the receipt of state and
federal funding.

PG&E has recently announced its intention to sell all of its power
generating facilities in The Geysers that purchase steam from TPC and the PG&E
Unit 13 and PG&E Unit 16 Steam Fields. The Company cannot predict the impact
that any such sale would have on the Company's results of operations or
financial condition.

23
26

In conjunction with Union Oil and NEC, TPC holds a right of first refusal
to match any sales offer for PG&E's 12 power plants which are served by the
Thermal Power Company Steam Fields. It cannot be determined at this time whether
PG&E will complete the sale of the power plants or whether Union Oil, NEC and
TPC will exercise their right of first refusal. On February 13, 1998, Union Oil,
NEC and TPC filed a protest with the CPUC objecting to certain aspects of PG&E's
application to sell the power plants. In addition, Union Oil, NEC and TPC have
commenced arbitration proceedings with PG&E under the steam sales agreement in a
dispute over the interpretation of contract provisions concerning minimum
operation levels of the power plants.

During 1997, the PG&E power plants produced 3,487,592,000 kilowatt hours of
electrical energy of which the Company's 25% share is 871,898,000 kilowatt hours
for approximately $15.8 million of revenue.

PG&E Unit 13 and Unit 16 Steam Fields

The Company holds the leasehold rights to 1,631 acres of steam fields (the
"PG&E Unit 13 and Unit 16 Steam Fields") that supply steam to PG&E's Unit 13
power plant (the "Unit 13") and PG&E's Unit 16 power plant (the "Unit 16"), all
of which are located in The Geysers. The PG&E Unit 13 Steam Field includes 956
acres, 28 production wells, five injection wells and five miles of pipeline, and
commenced commercial operations in May 1980. The PG&E Unit 16 Steam Field
includes 675 acres, 19 producing wells, two injection wells, and three miles of
pipeline, and commenced commercial operation in October 1985.

The PG&E Unit 13 and Unit 16 Steam Fields produce steam for sale to PG&E
under long-term steam sales agreements. Under the steam sales agreements with
PG&E, the Company is paid for steam on the basis of the amount of electricity
produced by Unit 13 and Unit 16. The price paid for steam under the PG&E Unit 13
and Unit 16 Steam Fields agreements is determined according to a formula that is
essentially a weighted average of PG&E's fossil (oil and gas) fuel price and
PG&E's nuclear fuel price. The price of steam for 1997 was 0.95c per kilowatt
hour. The Company receives an additional 0.05c per kilowatt hour from PG&E for
the disposal of liquid effluents produced at Unit 13 and Unit 16.

During conditions of hydro-spill, PG&E may curtail energy deliveries from
Unit 13 and Unit 16 which would reduce deliveries of steam under this agreement.
Curtailments are primarily the result of a higher degree of precipitation during
the period, which results in higher levels of energy generation by hydroelectric
power facilities that supply electricity for sale by PG&E. In the event of any
such curtailment, the Company's results of operations may be materially
adversely affected. PG&E curtailed approximately 37,371,590 kilowatt hours under
the steam sales agreement during 1997.

The steam sales agreement with PG&E continues in effect for as long as
either Unit 13 or Unit 16 remains in commercial operation for PG&E, which
depends in part on maintaining the productive capacity of the respective steam
fields. However, PG&E may terminate the agreement if the quantity, quality or
purity of the steam is such that the operation of Unit 13 or Unit 16 becomes
economically impractical. No assurance can be given that the operation of either
Unit 13 or Unit 16 will not become economically impractical at any time.

The Company is required to supply a sufficient quantity of steam of
specified quality to Unit 16. If an insufficient quantity of steam is delivered,
the Company may be subject to penalty provisions, including suspension of PG&E's
obligation to pay for steam delivered. Specifically, if the Company fails to
deliver to Unit 16 in any calendar month a sufficient quantity of steam adequate
to operate the power plant at or above a capacity factor of 50%, no payment
shall be made for steam delivered to such Unit during such month until the cost
of that Unit has been completely amortized by PG&E.

In order to increase the efficiency of Unit 13 by approximately 20%, the
Company agreed to purchase new rotors for $10.8 million. In exchange, PG&E
agreed to amend the steam sales agreement to remove the penalty provision for a
failure to deliver a sufficient quantity of steam to Unit 13 and to require PG&E
to operate at variable pressure operations which will optimize production at the
PG&E Unit 13 and Unit 16 Steam Fields.

24
27

The PG&E Unit 13 and Unit 16 Steam Fields currently supply steam sufficient
to operate Unit 13 and Unit 16 at approximately 77% of their combined nameplate
capacities. This percentage reflects a decline in the productivity of the PG&E
Unit 13 and Unit 16 Steam Fields since the commencement of operations of Unit 13
and Unit 16. While it is not possible to accurately predict long-term steam
field productivity, the Company has estimated that the annual rate of decline in
steam field productivity of the PG&E Unit 13 and Unit 16 Steam Fields was
approximately 6.0% in 1997. The Company expects steam field productivity to
continue to decline in the future, but at reduced annual rates of decline. The
Company considered these declines in steam field productivity in developing its
original projections for the PG&E Unit 13 and Unit 16 Steam Fields at the time
the Company acquired its initial interest in 1990. The Company plans to
partially offset the expected rate of decline by implementing enhanced water
injection and power plant improvements.

PG&E has recently announced its intention to sell all of its power
generating facilities in The Geysers that purchase steam from Thermal Power
Company and the PG&E Unit 13 and PG&E Unit 16 Steam Fields. The Company cannot
predict the impact that any such sale would have on the Company's results of
operations or financial condition.

The Company has filed a protest with the CPUC challenging certain aspects
of PG&E's application to sell Units 13 and 16. In addition, the Company has
filed an action in state court seeking a declaratory judgment and injunctive
relief to prohibit PG&E from assigning the steam contract to a third party
through its sale of the power plants.

During 1997, the PG&E Unit 13 and Unit 16 Steam Fields produced sufficient
steam to permit Unit 13 and Unit 16 to produce approximately 1,295,000,000
kilowatt hours of electrical energy and approximately $13.0 million of revenue.

SMUDGEO #1 Steam Fields

The Company holds the leasehold rights to 394 acres of steam fields that
supply steam to the power plant for the Sacramento Municipal Utility District
("SMUD") SMUDGEO #1 steam fields (the "SMUDGEO #1 Steam Fields"). The SMUD power
plant has a nameplate capacity of 72 megawatts and currently operates at an
output of 50 megawatts. The SMUDGEO #1 Steam Fields include 19 producing wells,
one injection well and two and one half miles of pipeline. Commercial operation
of the SMUD power plant commenced in October 1983.

The steam sales agreement with SMUD provides that SMUD will pay for steam
based upon the quantity of steam delivered to the SMUD power plant. The current
price paid for steam delivered under the steam sales agreement is $1.818 per
thousand pounds of steam, which is adjusted semi-annually based on changes in
the Gross National Product Implicit Price Deflator Index and Producers Price
Index for Fuels, Related Products and Power. SMUD may suspend payments for steam
in any month if the Company is unable to deliver 50% of the steam requirement
until the cost of the plant and related facilities have been completely
amortized by the value of such steam delivered to the plant. The Company
receives an additional 0.15c. per kilowatt hour from SMUD for the disposal of
liquid effluents produced at the SMUDGEO #1 Steam Fields.

The steam sales agreement with SMUD continues until the expiration or
termination of the geothermal lease covering the SMUDGEO #1 Steam Fields, which
continues for so long as steam is produced in commercial quantities. The Company
and SMUD each have the right to terminate the agreement if their respective
operations become economically impractical. In the event that SMUD exercises its
right to terminate, the Company will have no further obligation to deliver steam
to the power plants.

The SMUDGEO #1 Steam Fields currently supply steam sufficient to operate
the SMUD power plant at approximately 69% of its nameplate capacity. This
percentage reflects a decline in the productivity of the SMUDGEO #1 Steam Fields
since commencement of operations.

During 1997, the SMUDGEO #1 Steam Fields produced approximately 6,924,000
thousand pounds of steam and approximately $13.1 million of revenue.

Cerro Prieto Steam Fields

In 1995, the Company entered into a series of agreements with Constructora
y Perforadora Latina, S.A. de C.V. ("Coperlasa") and certain of Coperlasa's
creditors pursuant to which the Company has agreed to invest up to $20 million
in the Cerro Prieto steam fields (the "Cerro Prieto Steam Fields") located in
Baja California, Mexico. The Cerro Prieto Steam Fields provide geothermal steam
to three geothermal power plants owned and operated by Comision Federal de
Electricidad ("CFE"), the Mexican national utility.

The Company's investment consists of a loan of $18.5 million and a $1.5
million payment for an option to purchase a 29% equity interest in Coperlasa for
$5.8 million.

The $18.5 million loan was made in installments throughout 1995 and 1996,
which provided capital to Coperlasa to fund the drilling of new wells and the
repair of existing wells to meet its performance under the agreement with CFE.
The loan matures in November 1999 and bears interest at an effective rate of
18.9% per annum. The Company is deferring the recognition of income on this loan
until the Cerro Prieto project generates sufficient cash flows available for
distribution to support the collectibility of interest earned.

Pursuant to a technical services agreement, the Company receives fees for
its technical services provided to Coperlasa. In addition, if the Company is
successful in assisting Coperlasa in producing steam at a lower cost, the
Company will receive 30% of the savings, if any.

The Cerro Prieto Steam Fields are located near the city of Mexicali, Baja
California, at the border of Baja California and the State of California. The
Cerro Prieto geothermal resource, which has been commercially produced by CFE
since 1973, provides approximately 70% of Baja California's electricity
requirements since this region is not connected to the Mexican national power
grid.

The steam sales agreement between Coperlasa and CFE was entered into in May
1991. Under this agreement, CFE pays for steam delivered up to 1,600 tons per
hour plus 10%. Payments for the steam delivered are made in Mexican pesos and
are adjusted on a specific unit-of-production basis by a formula that accounts
for the increases in inflation in Mexico and the United States, as well as for
the devaluation of the peso against the U.S. dollar. This agreement has a
termination date of October 2000.

GAS FIELDS

Montis Niger Gas Fields

On January 31, 1997, the Company purchased Montis Niger, Inc. a gas
production and pipeline company operating primarily in the Sacramento Basin in
northern California. On July 25, 1997, Montis Niger, Inc. was renamed Calpine
Gas Company. As of January 1, 1998, Calpine Gas Company had approximately 8.1
billion cubic feet of proven natural gas reserves and approximately 16,094 gross
acres and 15,037 net acres under lease in the Sacramento Basin. In addition,
Calpine Gas Company owns and operates an 80-mile pipeline delivering gas to the
Greenleaf 1 and 2 Power Plants which had been either produced by Calpine Gas
Company or purchased from third parties. Calpine Gas Company currently supplies
approximately 80% of the fuel requirements for the Greenleaf 1 and 2 Power
Plants.

PROJECT DEVELOPMENT AND ACQUISITION

The Company is actively engaged in the development and acquisition of power
generation projects. The Company has historically focused principally on the
development and acquisition of interests in gas-fired and geothermal power
projects, although the Company also considers projects that utilize other power
generation technologies. The Company has significant expertise in a variety of
power generation technologies and has substantial capabilities in each aspect of
the development and acquisition process, including design, engineering,
procurement, construction management, fuel and resource acquisition and
management, financing and operations.

26
29

PROJECT DEVELOPMENT

The development of power generation projects involves numerous elements,
including evaluating and selecting development opportunities, designing and
engineering the project, obtaining power and steam sales agreements, acquiring
necessary land rights, permits and fuel resources, obtaining financing, and
managing construction. The Company intends to focus primarily on development
opportunities where the Company is able to capitalize on its expertise in
implementing an innovative and fully integrated approach to project development
in which the Company controls the entire development process. Utilizing this
approach, the Company believes that it is able to enhance the value of its
projects throughout each stage of development in an effort to maximize its
return on investment.

The Company is pursuing the development of highly efficient, low-cost
merchant power plants that seek to take advantage of inefficiencies in the
electricity market. The Company intends to sell all or a portion of the power
generated by such merchant plants into the competitive market through a
portfolio of short-, medium-and long-term power sales agreements. The Company
expects that these projects will represent a prototype for future merchant plant
developments by the Company. The Company currently plans to develop additional
low-cost, gas-fired facilities in California, Texas, New England and other high
priced power markets.

The development of power generation facilities is subject to substantial
risks. In connection with the development of a power generation facility, the
Company must generally obtain power and/or steam sales agreements, governmental
permits and approvals, fuel supply and transportation agreements, sufficient
equity capital and debt financing, electrical transmission agreements, site
agreements and construction contracts, and there can be no assurance that the
Company will be successful in doing so. In addition, project development is
subject to certain environmental, engineering and construction risks relating to
cost-overruns, delays and performance. Although the Company may attempt to
minimize the financial risks in the development of a project by securing a
favorable long-term power sales agreement, entering into power marketing
transactions, obtaining all required governmental permits and approvals and
arranging adequate financing prior to the commencement of construction, the
development of a power project may require the Company to expend significant
sums for preliminary engineering, permitting and legal and other expenses before
it can be determined whether a project is feasible, economically attractive or
financeable. If the Company were unable to complete the development of a
facility, it would generally not be able to recover its investment in such a
facility. The process for obtaining initial environmental, siting and other
governmental permits and approvals is complicated and lengthy, often taking more
than one year, and is subject to significant uncertainties. As a result of
competition, it may be difficult to obtain a power sales agreement for a
proposed project, and the prices offered in new power sales agreements for both
electric capacity and energy may be less than the prices in prior agreements.
There can be no assurance that the Company will be successful in the development
of power generation facilities in the future.

Pasadena Power Plant

Calpine has entered into a development agreement with Phillips Petroleum
Company ("Phillips") to construct and operate a 240 megawatt, gas-fired
cogeneration project at the Phillips Houston Chemical Complex ("HCC") located in
Pasadena, Texas (the "Pasadena Power Plant"). On December 19, 1996, the Company
entered into an Energy Sales Agreement with Phillips pursuant to which Phillips
will purchase all of the HCC's steam and electricity requirements of
approximately 90 megawatts. It is anticipated that the remainder of available
electricity output will be sold into the competitive market through Calpine's
power sales activities. On December 20, 1996, the Company entered into a credit
agreement with ING U.S. Capital Corporation to provide $151.8 million of
construction loans and $98.6 million of term loan non-recourse project financing
for the Pasadena Power Plant. In accordance with the terms of the agreement,
Calpine contributed $53.1 million in equity to the project. The Company
commenced construction in February 1997, with commercial operation scheduled to
begin in July 1998.

27
30

Dighton and Tiverton Power Plants

In October 1997, Calpine entered into agreements with Energy Management
Inc. ("EMI"), a New England based power developer, to invest in the development
of two merchant power plants in New England, including a 169 megawatt gas-fired
combined-cycle merchant power plant to be located in Dighton, Massachusetts (the
"Dighton Power Plant") and a 265 megawatt gas-fired power plant to be located in
Tiverton, Rhode Island (the "Tiverton Power Plant"). The Company intends to
invest $43.0 million of equity in the development of the Tiverton Power Plant.
In October 1997, the Company invested $16.0 million in the development of the
Dighton Power Plant. This investment, which is structured as subordinated debt,
will provide the Company with a preferred payment stream at a rate of 12.07% per
annum for a period of twenty years from the commercial operation date. The
Dighton Power Plant is being developed by EMI. It is estimated that the
development of the Dighton Power Plant will cost approximately $120.0 million,
which is being financed, in part, with $104.0 million of non-recourse
construction financing. Upon commercial operation, EMI is expected to contribute
$2.0 million of equity and the construction financing will convert to a $102.0
million term loan non-recourse project financing. Construction commenced in the
fourth quarter of 1997 and commercial operation is scheduled to begin in early
1999. Upon completion, the Dighton Power Plant will be operated by EMI and will
sell its output into the New England Power Pool and to wholesale and retail
customers in the northeastern United States.

Pursuant to a letter agreement with EMI providing for an exclusivity period
for negotiations through March 31, 1998, the Company intends to invest up to
$43.0 million of equity in the development of the Tiverton Power Plant. The
Tiverton Power Plant is being developed by EMI. It is estimated that the
development of the Tiverton Power Plant will cost approximately $173.0 million.
Construction is currently scheduled to commence in late 1998 and commercial
operation is scheduled for early 2000. Upon completion, the Tiverton Power Plant
will be operated by EMI and will sell its output in the New England Power Pool
and to wholesale and retail customers in the northeastern United States.

Magic Valley Power Plant

On January 21, 1998, Calpine announced that it had been selected by Magic
Valley Electric Cooperative, Inc., located in South Texas, to begin final
negotiations to supply its electric needs from 2001 through 2021. The Company
expects the electricity will be supplied by a 700 megawatt gas-fired merchant
power plant currently under development by the Company in Edinburg, Texas.

Sutter Power Plant

In February 1997, the Company announced plans to develop a 500 megawatt
gas-fired combined cycle project in Sutter County, in northern California (the
"Sutter Power Plant"). The Sutter Power Plant would be northern California's
first newly constructed merchant power plant. The Sutter Power Plant is expected
to provide electricity to the deregulated California power market commencing in
the year 2000. The Company is currently pursuing regulatory agency permits for
this project. On January 21, 1998, the Company announced that the Sutter Power
Plant has met the California Energy Commission's Data Adequacy requirements in
its Application for Certification.

ACQUISITIONS

The Company will consider the acquisition of an interest in operating
projects as well as projects under development where Calpine would assume
responsibility for completing the development of the project. In the acquisition
of power generation facilities, Calpine generally seeks to acquire an ownership
interest in facilities that offer the Company attractive opportunities for
revenue and earnings growth, that have existing, favorable long-term power sales
agreements with major electric utilities or major users of power (i.e.,
industrial facilities), and that permit the Company to assume sole
responsibility for the operation and maintenance of the facility. In evaluating
and selecting a project for acquisition, the Company considers a variety of
factors, including the type of power generation technology utilized, the
location of the project, the terms of any existing power or thermal energy sales
agreements, gas supply and transportation agreements and wheeling

28
31

agreements, the quantity and quality of any geothermal or other natural resource
involved, and the actual condition of the physical plant. In addition, the
Company assesses the past performance of an operating project and prepares
financial projections to determine the profitability of the project. The Company
generally seeks to obtain a significant equity interest in a project and to
obtain the operation and maintenance contract for that project.

The Company has grown substantially in recent years as a result of
acquisitions of interests in power generation facilities and steam fields. The
Company believes that although the domestic power industry is undergoing
consolidation and that significant acquisition opportunities are available, the
Company is likely to confront significant competition for acquisition
opportunities. In addition, there can be no assurance that the Company will
continue to identify attractive acquisition opportunities at favorable prices
or, to the extent that any opportunities are identified, that the Company will
be able to consummate such acquisitions.

Pittsburg Power Plant

On February 18, 1998, the Company announced that it has entered into
exclusive negotiations for a four month period ending May 31, 1998, with The Dow
Chemical Company ("Dow") to acquire its 70 megawatt gas-fired power plant and a
natural gas pipeline system located adjacent to Dow's chemical plant in
Pittsburg, California. The pipeline delivers low-cost fuel to the plant from
Sacramento Basin gas fields. As part of the transaction, The Company will enter
into long-term agreements with Dow to provide electricity and steam to its
chemical facility and steam to the nearby USS-POSCO Industries steel mill. In
addition, the Company will acquire rights to a site at the Dow chemical facility
suitable for future expansion. The Company expects to complete the acquisition
during the second quarter of 1998.

GOVERNMENT REGULATION

The Company is subject to complex and stringent energy, environmental and
other governmental laws and regulations at the federal, state and local levels
in connection with the development, ownership and operation of its energy
generation facilities. Federal laws and regulations govern transactions by
electrical and gas utility companies, the types of fuel which may be utilized by
an electric generating plant, the type of energy which may be produced by such a
plant and the ownership of a plant. State utility regulatory commissions must
approve the rates and, in some instances, other terms and conditions under which
public utilities purchase electric power from independent producers and sell
retail electric power. Under certain circumstances where specific exemptions are
otherwise unavailable, state utility regulatory commissions may have broad
jurisdiction over non-utility electric power plants. Energy producing projects
also are subject to federal, state and local laws and administrative regulations
which govern the emissions and other substances produced, discharged or disposed
of by a plant and the geographical location, zoning, land use and operation of a
plant. Applicable federal environmental laws typically have both state and local
enforcement and implementation provisions. These environmental laws and
regulations generally require that a wide variety of permits and other approvals
be obtained before the commencement of construction or operation of an energy-
producing facility and that the facility then operate in compliance with such
permits and approvals.

FEDERAL ENERGY REGULATION

PURPA

The enactment of the Public Utility Regulatory Policies Act of 1978, as
amended ("PURPA") and the adoption of regulations thereunder by FERC provided
incentives for the development of cogeneration facilities and small power
production facilities (those utilizing renewable fuels and having a capacity of
less than 80 megawatts).

A domestic electricity generating project must be a QF under FERC
regulations in order to take advantage of certain rate and regulatory incentives
provided by PURPA. PURPA exempts owners of QFs from the Public Utility Holding
Company Act of 1935, as amended ("PUHCA"), and exempts QFs from most provisions
of the Federal Power Act (the "FPA") and, except under certain limited
circumstances, state

29
32

laws concerning rate or financial regulation. These exemptions are important to
the Company and its competitors. The Company believes that each of the
electricity generating projects in which the Company owns an interest currently
meets the requirements under PURPA necessary for QF status. Most of the projects
which the Company is currently planning or developing are also expected to be
QFs.

PURPA provides two primary benefits to QFs. First, QFs generally are
relieved of compliance with extensive federal, state and local regulations that
control the financial structure of an electric generating plant and the prices
and terms on which electricity may be sold by the plant. Second, the FERC's
regulations promulgated under PURPA require that electric utilities purchase
electricity generated by QFs at a price based on the purchasing utility's
"avoided cost," and that the utility sell back-up power to the QF on a non-
discriminatory basis. The term "avoided cost" is defined as the incremental cost
to an electric utility of electric energy or capacity, or both, which, but for
the purchase from QFs, such utility would generate for itself or purchase from
another source. The FERC regulations also permit QFs and utilities to negotiate
agreements for utility purchases of power at rates lower than the utility's
avoided costs. Due to increasing competition for utility contracts, the current
practice is for most power sales agreements to be awarded at a rate below
avoided cost. While public utilities are not explicitly required by PURPA to
enter into long-term power sales agreements, PURPA helped to create a regulatory
environment in which it has been common for long-term agreements to be
negotiated.

In order to be a QF, a cogeneration facility must produce not only
electricity, but also useful thermal energy for use in an industrial or
commercial process for heating or cooling applications in certain proportions to
the facility's total energy output and must meet certain energy efficiency
standards. Finally, a QF (including a geothermal or hydroelectric QF or other
qualifying small power producer) must not be controlled or more than 50% owned
by an electric utility or by most electric utility holding companies, or a
subsidiary of such a utility or holding company or any combination thereof.

The Company endeavors to develop its projects, monitor compliance by the
projects with applicable regulations and choose its customers in a manner which
minimizes the risks of any project losing its QF status. Certain factors
necessary to maintain QF status are, however, subject to the risk of events
outside the Company's control. For example, loss of a thermal energy customer or
failure of a thermal energy customer to take required amounts of thermal energy
from a cogeneration facility that is a QF could cause the facility to fail
requirements regarding the level of useful thermal energy output. Upon the
occurrence of such an event, the Company would seek to replace the thermal
energy customer or find another use for the thermal energy which meets PURPA's
requirements, but no assurance can be given that this would be possible.

If one of the projects in which the Company has an interest should lose its
status as a QF, the project would no longer be entitled to the exemptions from
PUHCA and the FPA. This could trigger certain rights of termination under the
power sales agreement, could subject the project to rate regulation as a public
utility under the FPA and state law and could result in the Company
inadvertently becoming a public utility holding company by owning more than 10%
of the voting securities of, or controlling, a facility that would no longer be
exempt from PUHCA. This could cause all of the Company's remaining projects to
lose their qualifying status, because QFs may not be controlled or more than 50%
owned by such public utility holding companies. Loss of QF status may also
trigger defaults under covenants to maintain QF status in the projects' power
sales agreements, steam sales agreements and financing agreements and result in
termination, penalties or acceleration of indebtedness under such agreements
such that loss of status may be on a retroactive or a prospective basis.

If a project were to lose its QF status, the Company could attempt to avoid
holding company status (and thereby protect the QF status of its other projects)
on a prospective basis by restructuring the project, by changing its voting
interest in the entity owning the non-qualifying project to nonvoting or limited
partnership interests and selling the voting interest to an individual or
company which could tolerate the lack of exemption from PUHCA, or by otherwise
restructuring ownership of the project so as not to become a holding company.
These actions, however, would require approval of the Securities and Exchange
Commission ("SEC") or a no-action letter from the SEC, and would result in a
loss of control over the non-qualifying project, could result in a reduced
financial interest therein and might result in a modification of the Company's
operation and

30
33

maintenance agreement relating to such project. A reduced financial interest
could result in a gain or loss on the sale of the interest in such project, the
removal of the affiliate through which the ownership interest is held from the
consolidated income tax group or the consolidated financial statements of the
Company, or a change in the results of operations of the Company. Loss of QF
status on a retroactive basis could lead to, among other things, fines and
penalties being levied against the Company and its subsidiaries and claims by
utilities for refund of payments previously made.

Under the Energy Policy Act of 1992, if a project can be qualified as an
exempt wholesale generator ("EWG"), it will be exempt from PUHCA even if it does
not qualify as a QF. Therefore, another response to the loss or potential loss
of QF status would be to apply to have the project qualified as an EWG. However,
assuming this changed status would be permissible under the terms of the
applicable power sales agreement, rate approval from FERC and approval of the
utility would be required. In addition, the project would be required to cease
selling electricity to any retail customers (such as the thermal energy
customer) and could become subject to state regulation of sales of thermal
energy.

Currently, Congress is considering proposed legislation that would amend
PURPA by eliminating the requirement that utilities purchase electricity from
QFs at avoided costs. The Company does not know whether such legislation will be
passed or what form it may take. The Company believes that if any such
legislation is passed, it would apply to new projects. As a result, although
such legislation may adversely affect the Company's ability to develop new
projects, the Company believes it would not affect the Company's existing QFs.
There can be no assurance, however, that any legislation passed would not
adversely impact the Company's existing projects.

Public Utility Holding Company Regulation

Under PUHCA, any corporation, partnership or other legal entity which owns
or controls 10% or more of the outstanding voting securities of a "public
utility company" or a company which is a "holding company" for a public utility
company is subject to registration with the SEC and regulation under PUHCA,
unless eligible for an exemption. A holding company of a public utility company
that is subject to registration is required by PUHCA to limit its utility
operations to a single integrated utility system and to divest any other
operations not functionally related to the operation of that utility system.
Approval by the SEC is required for nearly all important financial and business
dealings of the holding company. Under PURPA, most QFs are not public utility
companies under PUHCA.

The Energy Policy Act of 1992, among other things, amends PUHCA to allow
EWGs, under certain circumstances, to own and operate non-QFs without subjecting
those producers to registration or regulation under PUHCA. The expected effect
of such amendments would be to enhance the development of non-QFs which do not
have to meet the fuel, production and ownership requirements of PURPA. The
Company believes that the amendments could benefit the Company by expanding its
ability to own and operate facilities that do not qualify for QF status, but may
also result in increased competition by allowing utilities to develop such
facilities which are not subject to the constraints of PUHCA.

Federal Natural Gas Transportation Regulation

The Company has an ownership interest in and operates ten gas-fired
cogeneration projects. The cost of natural gas is ordinarily the largest expense
(other than debt costs) of a project and is critical to the project's economics.
The risks associated with using natural gas can include the need to arrange
transportation of the gas from great distances, including obtaining removal,
export and import authority if the gas is transported from Canada; the
possibility of interruption of the gas supply or transportation (depending on
the quality of the gas reserves purchased or dedicated to the project, the
financial and operating strength of the gas supplier, and whether firm or
non-firm transportation is purchased); and obligations to take a minimum
quantity of gas and pay for it (i.e., take-and-pay obligations).

Pursuant to the Natural Gas Act, FERC has jurisdiction over the
transportation and storage of natural gas in interstate commerce. With respect
to most transactions that do not involve the construction of pipeline
facilities, regulatory authorization can be obtained on a self-implementing
basis. However, pipeline rates for

31
34

such services are subject to continuing FERC oversight. Order No. 636, issued by
FERC in April 1992, mandates the restructuring of interstate natural gas
pipeline sales and transportation services and will result in changes in the
terms and conditions under which interstate pipelines will provide
transportation services, as well as the rates pipelines may charge for such
services. The restructuring required by the rule includes (i) the separation
(unbundling) of a pipeline's sales and transportation services, (ii) the
implementation of a straight fixed-variable rate design methodology under which
all of a pipeline's fixed costs are recovered through its reservation charge,
(iii) the implementation of a capacity releasing mechanism under which holders
of firm transportation capacity on pipelines can release that capacity for
resale by the pipeline and (iv) the opportunity for pipelines to recover 100% of
their prudently incurred costs (transition costs) associated with implementing
the restructuring mandated by the rule. Pipelines were required to file tariff
sheets implementing Order No. 636 by December 31, 1992. FERC affirmed the major
components of Order No. 636 in Order Nos. 636A and B issued in August and
November 1992. The restructuring required by the rule became effective in late
1993.

STATE REGULATION

State public utility commissions ("PUCs") have historically had broad
authority to regulate both the rates charged by, and the financial activities
of, electric utilities and to promulgate regulation for implementation of PURPA.
Since a power sales agreement becomes a part of a utility's cost structure
(generally reflected in its retail rates), power sales agreements with
independent electricity producers are potentially under the regulatory purview
of PUCs and in particular the process by which the utility has entered into the
power sales agreements. If a PUC has approved the process by which a utility
secures its power supply, a PUC is generally inclined to "pass through" the
expense associated with an independent power contract to the utility's retail
customer. However, a regulatory commission under certain circumstances may
disallow the full reimbursement to a utility for the cost to purchase power from
a QF. In addition, retail sales of electricity or thermal energy by an
independent power producer may be subject to PUC regulation depending on state
law. Independent power producers which are not QFs under PURPA, or EWGs pursuant
to the Energy Policy Act of 1992, are considered to be public utilities in many
states and are subject to broad regulation by a PUC, ranging from requirement of
certificate of public convenience and necessity to regulation of organizational,
accounting, financial and other corporate matters. States may assert
jurisdiction over the siting and construction of electric generating facilities
including QFs and, with the exception of QFs, over the issuance of securities
and the sale or other transfer of assets by these facilities.

The California Public Utilities Commission ("CPUC") and the California
Joint Legislative Committee on Lowering the Cost of Electric Services commenced
proceedings and hearings related to the restructure of the California electric
services industry in 1994. The proceedings and hearings were initiated as a
result of the CPUC study and Order Instituting Rulemaking and Order Instituting
Investigation on the Commission's Proposed Policies Governing Restructuring
California's Electric Services Industry and Reforming Regulation, issued by the
CPUC on April 20, 1994. The FERC, as authorized under the Energy Policy Act of
1992, has also initiated proceedings and continues to hold workshops and
hearings on policy issues related to a more competitive electric services
industry. Though the state of California appears to be at the forefront, many
other states are in various stages of review and interest in deregulation,
moving toward a more competitive electric services industry.

On December 20, 1995, the CPUC issued its decision on California electric
industry restructure which envisioned commencement of deregulation and
implementation of customer choice beginning January 1, 1998, with all customers
participating by 2003. The decision provided for phased-in customer choice,
development of a non-discriminatory market structure, full recovery of utility
stranded costs, sanctity of existing contracts, and continuation of existing
public purpose programs including promotion of fuel diversity through a
renewable energy purchase requirement. On February 5, 1996, the CPUC issued a
procedural plan to facilitate the transition of the electric generation market
to competition. The electric restructuring roadmap focused on the multiple and
interrelated tasks to be accomplished and set forth the process to achieve the
necessary procedural milestones to be completed in order to meet the restructure
implementation goal.

32
35

In 1996, the Joint Legislative Conference Committee held hearings related
to electric industry restructure and drafted legislation, AB 1890 (the "Bill"),
which was approved by the legislature in August 1996 and signed by the Governor
on September 23, 1996. The legislation codifies much of the December CPUC
decision as modified in January 1996 and directed the CPUC to proceed with
resolve of outstanding issues resulting in implementation of restructure no
later than January 1, 1998. The Bill accelerated the transition period in which
utilities are allowed to recover their stranded costs from five years to four
years, continued to provide for sanctity of existing contracts with provisions
for voluntary restructure, established an electricity rate freeze for the
transition period and mandated a 10% rate reduction effective January 1, 1998
for small commercial and residential customers through issuance of rate
reduction bonds, and replaced the CPUC renewable technology purchase requirement
with funds specified for use in public service programs.

On December 20, 1996, the CPUC responded to the legislation and issued an
updated procedural roadmap consistent with provisions included in the Bill.
Proceedings are ongoing at the CPUC and FERC for establishment of an Independent
Systems Operator ("ISO") responsible for centralized control and efficient and
reliable operation of the state-wide electric transmission grid, and a Power
Exchange ("PX") responsible for an efficient competitive electric energy auction
open on a non-discriminatory basis to all electric services providers. Other
proceedings now ongoing include the quantification and qualification of utility
stranded costs to be eligible for recovery through competitive transition
charges ("CTC"), market power mitigation through utility divestiture of fossil
generation plants (Pacific Gas & Electric 50%; Southern California Edison,
100%), the unbundling and establishment of rate structure for historical utility
functions, the continuation of public purpose programs and issues related to
issuance of rate reduction bonds. On May 6, 1997, the CPUC issued decisions
which eliminated phase-in and provided for implementation of direct access for
all customers beginning January 1, 1998, and the unbundling of revenue cycle
services, thereby allowing all electric service providers to participate in
metering and billing services. The CPUC has subsequently extended the
implementation date to April 1, 1998.

The California Energy Commission ("CEC") and Legislature have
responsibility for development of a competitive market mechanism for allocation
and distribution of funds made available by the legislation for enhancement of
in-state renewable resource technologies and public interest research and
development programs. Funds are to be available through the four-year transition
period to a fully competitive electric services industry.

In addition to the significant opportunity provided for power producers
such as Calpine through implementation of customer choice (direct access), the
CPUC decision and the AB 1890 restructuring legislation both recognize the
sanctity of existing contracts, provide for mitigation of utility horizontal
market power through divestiture of fossil generation and provide funds for
continuation of public services programs including fuel diversity through
enhancement for in-state renewable technologies (includes geothermal) for the
four-year transition period to a fully competitive electric services industry.

State PUCs also have jurisdiction over the transportation of natural gas by
local distribution companies ("LDCs"). Each state's regulatory laws are somewhat
different; however, all generally require the LDC to obtain approval from the
PUC for the construction of facilities and transportation services if the LDC's
generally applicable tariffs do not cover the proposed transaction. LDC rates
are usually subject to continuing PUC oversight.

REGULATION OF CANADIAN GAS

The Canadian natural gas industry is subject to extensive regulation by
governmental authorities. At the federal level, a party exporting gas from
Canada must obtain an export license from the Canadian National Energy Board
("NEB"). The NEB also regulates Canadian pipeline transportation rates and the
construction of pipeline facilities. Gas producers also must obtain a removal
permit or license from provincial authorities before natural gas may be removed
from the province, and provincial authorities may regulate intra-provincial
pipeline and gathering systems. In addition, a party importing natural gas into
the United States first must obtain an import authorization from the U.S.
Department of Energy.

ENVIRONMENTAL REGULATIONS

The exploration for and development of geothermal resources and the
construction and operation of power projects are subject to extensive federal,
state and local laws and regulations adopted for the protection of the
environment and to regulate land use. The laws and regulations applicable to the
Company primarily involve the discharge of emissions into the water and air and
the use of water, but can also include wetlands preservation, endangered
species, waste disposal and noise regulations. These laws and regulations in
many cases require a lengthy and complex process of obtaining licenses, permits
and approvals from federal, state and local agencies.

Noncompliance with environmental laws and regulations can result in the
imposition of civil or criminal fines or penalties. In some instances,
environmental laws also may impose clean-up or other remedial obligations in the
event of a release of pollutants or contaminants into the environment. The
following federal laws are among the more significant environmental laws as they
apply to the Company. In most cases, analogous state laws also exist that may
impose similar, and in some cases more stringent, requirements on the Company as
those discussed below.

Clean Air Act

The Federal Clean Air Act of 1970 (the "Clean Air Act") provides for the
regulation, largely through state implementation of federal requirements, of
emissions of air pollutants from certain facilities and operations. As
originally enacted, the Clean Air Act sets guidelines for emissions standards
for major pollutants (i.e., sulfur dioxide and nitrogen oxide) from newly built
sources. In late 1990, Congress passed the Clean Air Act Amendments (the "1990
Amendments"). The 1990 Amendments attempt to reduce emissions from existing
sources, particularly previously exempted older power plants. The Company
believes that all of the Company's operating plants are in compliance with
federal performance standards mandated for such plants under the Clean Air Act
and the 1990 Amendments. With respect to its Aidlin geothermal plant and one of
its steam field pipelines, the Company's operations have, in certain instances,
necessitated variances under applicable California air pollution control laws.
However, the Company believes that it is in compliance with such laws with
respect to such facilities.

Clean Water Act

The Federal Clean Water Act (the "Clean Water Act") establishes rules
regulating the discharge of pollutants into waters of the United States. The
Company is required to obtain a wastewater and storm water discharge permit for
wastewater and runoff, respectively, from certain of the Company's facilities.
The Company believes that, with respect to its geothermal operations, it is
exempt from newly promulgated federal storm water requirements. The Company
believes that it is in compliance with applicable discharge requirements under
the Clean Water Act.

Resource Conservation and Recovery Act

The Resource Conservation and Recovery Act ("RCRA") regulates the
generation, treatment, storage, handling, transportation and disposal of solid
and hazardous waste. The Company believes that it is exempt from solid waste
requirements under RCRA. However, particularly with respect to its solid waste
disposal practices at the power generation facilities and steam fields located
at The Geysers, the Company is subject to certain solid waste requirements under
applicable California laws. The Company believes that its operations are in
compliance with such laws.

Comprehensive Environmental Response, Compensation, and Liability Act

The Comprehensive Environmental Response, Compensation and Liability Act of
1980, as amended ("CERCLA" or "Superfund"), requires cleanup of sites from which
there has been a release or threatened release of hazardous substances and
authorizes the United States Environmental Protection Agency ("EPA") to take any
necessary response action at Superfund sites, including ordering potentially
responsible parties ("PRPs") liable for the release to take or pay for such
actions. PRPs are broadly defined under CERCLA to

34
37

include past and present owners and operators of, as well as generators of
wastes sent to, a site. As of the present time, the Company is not subject to
liability for any Superfund matters. However, the Company generates certain
wastes, including hazardous wastes, and sends certain of its wastes to
third-party waste disposal sites. As a result, there can be no assurance that
the Company will not incur liability under CERCLA in the future.

RISK FACTORS

SUBSTANTIAL LEVERAGE

The Company is substantially leveraged as a result of outstanding
indebtedness of the Company and non-recourse debt financing of certain of the
Company's subsidiaries incurred to finance the acquisition and development of
power generation facilities. As of December 31, 1997, the Company's total
consolidated indebtedness was $855.9 million, its total consolidated assets were
$1.4 billion and its stockholders' equity was $240.0 million. The ability of the
Company to meet its debt service obligations and to repay outstanding
indebtedness according to its terms will be dependent primarily upon the
performance of the power generation facilities in which the Company has an
interest.

On September 25, 1996, the Company entered into a $50.0 million three-year
revolving credit facility with The Bank of Nova Scotia as agent (the "Revolving
Credit Facility"). The Revolving Credit Facility contains certain restrictions
that significantly limit or prohibit, among other things, the ability of the
Company or its subsidiaries to incur indebtedness, make prepayments of certain
indebtedness, pay dividends, make investments, engage in transactions with
affiliates, create liens, sell assets and engage in mergers and consolidations.

The Company believes that, based on current levels of operations and
anticipated growth, cash flow from operations, together with other available
sources of funds, including borrowings under the Company's existing borrowing
arrangements, will be adequate to make required payments of principal and
interest on the Company's debt, including the 8 3/4% Senior Notes, the 10 1/2%
Senior Notes and the 9 1/4% Senior Notes, and to enable the Company to comply
with the terms of its Indentures and other debt agreements, although there can
be no assurance that this will be the case. If the Company is unable to comply
with the terms of its Indentures and other debt agreements and fails to generate
sufficient cash flow from operations in the future, the Company may be required
to refinance all or a portion of its existing debt or to obtain additional
financing. There can be no assurance that any such refinancing would be possible
or that any additional financing could be obtained, particularly in view of the
Company's high levels of debt and the debt incurrence restrictions under
existing Indentures and other debt agreements. If cash flow is insufficient and
no such refinancing or additional financing is available, the Company may be
forced to default on its debt obligations. In the event of a default under the
terms of any of the indebtedness of the Company, subject to the terms of such
indebtedness, the obligees thereunder would be permitted to accelerate the
maturity of such obligations, which could cause defaults under other obligations
of the Company.

POSSIBLE UNAVAILABILITY OF FINANCING

Each power generation facility acquired or developed by the Company will
require substantial capital investment. The Company's ability to arrange
financing and the cost of such financing are dependent upon numerous factors,
including general economic and capital market conditions, conditions in energy
markets, regulatory developments, credit availability from banks or other
lenders, investor confidence in the industry and the Company, the continued
success of the Company's current power generation facilities, and provisions of
tax and securities laws that are conducive to raising capital. There can be no
assurance that financing for new facilities will be available to the Company on
acceptable terms in the future.

The Company's power generation facilities have been financed using a
variety of leveraged financing structures, primarily consisting of non-recourse
project financing and lease obligations. As of December 31, 1997, the Company
had approximately $855.9 million of total consolidated indebtedness, of which
approximately 35% represented non-recourse project financing. Each non-recourse
project financing and lease

35
38

obligation is structured to be fully paid out of cash flow provided by the
facility or facilities, the assets of which (together with pledges of stock or
partnership interests in the entity owning the facility) collateralize such
obligations, without any claim against the Company's general corporate funds.
Such leveraged financing permits the development of larger facilities, but also
increases the risk to the Company that its interest in a particular facility
could be impaired or that fluctuations in revenues could adversely affect the
Company's ability to meet its lease or debt obligations. The debt collateralized
by the interests of the Company in each operating facility reduces the liquidity
of such assets since any sale or transfer of a facility would be subject both to
the lien securing the facility indebtedness and to transfer restrictions in the
financing agreements. While the Company intends to utilize non-recourse or lease
financing when appropriate, there can be no assurance that market conditions and
other factors will permit the same limited equity investment by the Company or
the same substantially non-recourse nature of financings for future facilities.
In the event of a default under a financing agreement, and assuming the Company
or the other equity investors in a facility are unable or choose not to cure
such default within applicable cure periods, if any, the lenders or lessors
would generally have rights to the facility, any related geothermal resource or
natural gas reserves, related contracts and cash flows and all licenses and
permits necessary to operate the facility. In the event of foreclosure after
such a default, the Company might not retain any interest in such facility. The
Company does not believe the existence of non-recourse or lease financing will
materially affect its ability to continue to borrow funds in the future in order
to finance new facilities. There can be no assurance, however, that the Company
will continue to be able to obtain the financing required to develop its power
generation facilities on terms satisfactory to the Company.

The Company has from time to time guaranteed certain obligations of its
subsidiaries and other affiliates. There can be no assurance that, in respect of
any financings of facilities in the future, lenders or lessors will not require
the Company to guarantee the indebtedness of such future facilities, rendering
the Company's general corporate funds vulnerable in the event of a default by
such facility or related subsidiary.

IMPACT OF AVOIDED COST PRICING; ENERGY PRICE FLUCTUATIONS

PG&E pays a fixed price for each unit of electrical energy according to
schedules set forth in the long-term power sales agreements for the Bear Canyon
(20 megawatts) and West Ford Flat (27 megawatts) Power Plants. The fixed price
periods under these power sales agreements expire in September and December
1998, respectively. After the fixed price periods expire, while the basis for
the capacity and capacity bonus payments under these power sales agreements
remains the same, the energy payments adjust to interim short-run avoided cost
("SRAC"), which is calculated pursuant to the methodology approved by the CPUC
on December 9, 1996, and will continue at SRAC until the independent power
exchange has commenced operations and is functioning properly. The independent
power exchange is currently scheduled to commence operations on April 1, 1998.
Thereafter, SRAC will become the energy clearing price of the independent power
exchange (referred to herein as the "Power Exchange Price"). During 1997, SRAC
averaged approximately 2.94c per kilowatt hour. As a result, while SRAC does not
affect capacity payments under the power sales agreements, the Company's energy
revenue under these power sales agreements is expected to be materially reduced
at the expiration of the fixed price period. Such reduction may have a material
adverse effect on the Company's results of operations. The Company expects the
forecasted decline in energy revenues will be mitigated by decreased royalty
expenses and planned operating cost reductions at the facilities. In addition,
the Company will continue its strategy of offsetting such reductions through its
acquisition and development program. In addition, prices paid for the steam
delivered by the Company's steam fields are based on a formula that partially
reflects the price levels of nuclear and fossil fuels, and, therefore, a
reduction in the price levels of such fuels may reduce revenue under the steam
sales agreements for the steam fields.

POWER PROJECT DEVELOPMENT AND ACQUISITION RISKS

The development of power generation facilities is subject to substantial
risks. In connection with the development of a power generation facility, the
Company must generally obtain governmental permits and

36
39

approvals, fuel supply and transportation agreements, sufficient equity capital
and debt financing, electrical transmission agreements, site agreements and
construction contracts, and there can be no assurance that the Company will be
successful in doing so. In addition, project development is subject to certain
environmental, engineering and construction risks relating to cost-overruns,
delays and performance. Although the Company may attempt to minimize the
financial risks in the development of a project by securing a favorable
long-term power sales agreement, entering into power marketing transactions,
obtaining all required governmental permits and approvals and arranging adequate
financing prior to the commencement of construction, the development of a power
project may require the Company to expend significant sums for preliminary
engineering, permitting, legal and other expenses before it can be determined
whether a project is feasible, economically attractive or financeable. If the
Company were unable to complete the development of a facility, it would
generally not be able to recover its investment in such a facility. The process
for obtaining initial environmental, siting and other governmental permits and
approvals is complicated and lengthy, often taking more than one year, and is
subject to significant uncertainties. As a result of competition, it may be
difficult to obtain a power sales agreement for a proposed project, and the
prices offered in new power sales agreements for both electric capacity and
energy may be less than the prices in prior agreements. There can be no
assurance that the Company will be successful in the development of power
generation facilities in the future.

The Company has grown substantially in recent years as a result of
acquisitions of interests in power generation facilities and steam fields. The
Company believes that although the domestic power industry is undergoing
consolidation and that significant acquisition opportunities are available, the
Company is likely to confront significant competition for acquisition
opportunities. In addition, there can be no assurance that the Company will
continue to identify attractive acquisition opportunities at favorable prices
or, to the extent that any opportunities are identified, that the Company will
be able to consummate such acquisitions.

START-UP RISKS

The commencement of operation of a newly constructed power plant or steam
field involves many risks, including start-up problems, the breakdown or failure
of equipment or processes and performance below expected levels of output or
efficiency. New plants have no operating history and may employ recently
developed and technologically complex equipment. Insurance is maintained to
protect against certain of these risks, warranties are generally obtained for
limited periods relating to the construction of each project and its equipment
in varying degrees, and contractors and equipment suppliers are obligated to
meet certain performance levels. Such insurance, warranties or performance
guarantees may not be adequate to cover lost revenues or increased expenses and,
as a result, a project may be unable to fund principal and interest payments
under its financing obligations and may operate at a loss. A default under such
a financing obligation could result in the Company losing its interest in such
power generation facility or steam field.

In addition, power sales agreements, which are typically entered into with
a utility early in the development phase of a project, often enable the utility
to terminate such agreement, or to retain security posted as liquidated damages,
in the event that a project fails to achieve commercial operation or certain
operating levels by specified dates or fails to make certain specified payments.
In the event such a termination right is exercised, a project may not commence
generating revenues, the default provisions in a financing agreement may be
triggered (rendering such debt immediately due and payable) and the project may
be rendered insolvent as a result.

GENERAL OPERATING RISKS

The Company currently operates 16 out of 23 of the power generation
facilities and steam fields in which it has an interest. The continued operation
of power generation facilities and steam fields involves many risks, including
the breakdown or failure of power generation equipment, transmission lines,
pipelines or other equipment or processes and performance below expected levels
of output or efficiency. To date, the Company's power generation facilities have
operated at an average availability of approximately 97%, and although from time
to time the Company's power generation facilities and steam fields have
experienced certain equipment breakdowns or failures, such breakdowns or
failures have not had a material adverse effect on the operation of such
facilities or on the Company's results of operations. Although the Company's

37
40

facilities contain certain redundancies and back-up mechanisms, there can be no
assurance that any such breakdown or failure would not prevent the affected
facility or steam field from performing under applicable power and/or steam
sales agreements. In addition, although insurance is maintained to protect
against certain of these operating risks, the proceeds of such insurance may not
be adequate to cover lost revenues or increased expenses, and, as a result, the
entity owning such power generation facility or steam field may be unable to
service principal and interest payments under its financing obligations and may
operate at a loss. A default under such a financing obligation could result in
the Company losing its interest in such power generation facility or steam
field.

RISKS RELATED TO THE DEVELOPMENT AND OPERATION OF GEOTHERMAL ENERGY RESOURCES

The development and operation of geothermal energy resources are subject to
substantial risks and uncertainties similar to those experienced in the
development of oil and gas resources. The successful exploitation of a
geothermal energy resource ultimately depends upon the heat content of the
extractable fluids, the geology of the reservoir, the total amount of
recoverable reserves and operational factors relating to the extraction of
fluids, including operating expenses, energy price levels and capital
expenditure requirements relating primarily to the drilling of new wells. In
connection with the development of a project, the Company estimates the
productivity of the geothermal resource and the expected decline in such
productivity. The productivity of a geothermal resource may decline more than
anticipated, resulting in insufficient recoverable reserves being available for
sustained generation of the electrical power capacity desired. An incorrect
estimate by the Company or an unexpected decline in productivity could have a
material adverse effect on the Company's results of operations.

Geothermal reservoirs are highly complex, and, as a result, there exist
numerous uncertainties in determining the extent of the reservoirs and the
quantity and productivity of the steam reserves. Reservoir engineering is an
inexact process of estimating underground accumulations of steam or fluids that
cannot be measured in any precise way, and depends significantly on the quantity
and accuracy of available data. As a result, the estimates of other reservoir
specialists may differ materially from those of the Company. Estimates of
reserves are generally revised over time on the basis of the results of
drilling, testing and production that occur after the original estimate was
prepared. While the Company has extensive experience in the operation and
development of geothermal energy resources and in preparing such estimates,
there can be no assurance that the Company will be able to successfully manage
the development and operation of its geothermal reservoirs or that the Company
will accurately estimate the quantity or productivity of its steam reserves.

DEPENDENCE ON THIRD PARTIES

The nature of the Company's power generation facilities is such that each
facility generally relies on one power or steam sales agreement with a single
electric utility customer for substantially all, if not all, of such facility's
revenue over the life of the project. During 1997, approximately 80% and 5% of
the Company's total revenue was attributable to revenue received pursuant to
power and steam sales agreements with PG&E and SMUD, respectively. The power and
steam sales agreements are generally long-term agreements, covering the sale of
electricity or steam for initial terms of 20 or 30 years. However, the loss of
any one power or steam sales agreement with any of these utility customers could
have a material adverse effect on the Company's results of operations. In
addition, any material failure by any utility customer to fulfill its
obligations under a power or steam sales agreement could have a material adverse
effect on the cash flow available to the Company and, as a result, on the
Company's results of operations. PG&E has recently announced its intention to
sell all of its power generating facilities in The Geysers that purchase steam
from TPC and the PG&E Unit 13 and PG&E Unit 16 Steam Fields. Although there can
be no assurance, the Company does not expect that such sale, if consummated,
would have a material adverse impact on the Company's results of operations or
financial condition.

Furthermore, each power generation facility may depend on a single or
limited number of entities to purchase thermal energy, or to supply or transport
natural gas to such facility. The failure of any one utility customer, steam
host, gas supplier or gas transporter to fulfill its contractual obligations
could have a material adverse effect on a power project and on the Company's
business and results of operations.

INTERNATIONAL INVESTMENTS

The Company has made an investment in the Cerro Prieto geothermal steam
fields located in Mexico and may pursue additional international investments, in
selected countries. Such investments are subject to risks and uncertainties
relating to the political, social and economic structures of those countries.
Risks specifically related to investments in non-United States projects may
include risks of fluctuations in currency valuation, currency inconvertibility,
expropriation and confiscatory taxation, increased regulation and approval
requirements and governmental policies limiting returns to foreign investors.

GOVERNMENT REGULATION

The Company's activities are subject to complex and stringent energy,
environmental and other governmental laws and regulations. The construction and
operation of power generation facilities require numerous permits, approvals and
certificates from appropriate 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 laws, the Company remains subject to a varied and
complex body of laws and regulations that both public officials and private
individuals may seek to enforce. There can be no assurance that existing laws
and regulations will not be revised or that new laws and regulations will not be
adopted or become applicable to the Company that may have a material adverse
effect on the Company's business or results of operations, nor can there be any
assurance that the Company will be able to obtain all necessary licenses,
permits, approvals and certificates for proposed projects or that completed
facilities will comply with all applicable permit conditions, statutes or
regulations. In addition, regulatory compliance for the construction of new
facilities is a costly and time consuming process, and intricate and changing
environmental and other regulatory requirements may necessitate substantial
expenditures to obtain permits and may create a significant risk of expensive
delays or significant loss of value in a project if the project is unable to
function as planned due to changing requirements or local opposition.

The Company's operations are subject to the provisions of various energy
laws and regulations, including PURPA, PUHCA, and state and local regulations.
PUHCA provides for the extensive regulation of public utility holding companies
and their subsidiaries. PURPA provides to QFs and owners of QFs certain
exemptions from certain federal and state regulations, including rate and
financial regulations.

Under present federal law, the Company is not and will not be subject to
regulation as a holding company under PUHCA as long as the power plants in which
it has an interest are QFs under PURPA or are subject to another exemption. In
order to be a QF, a facility must be not more than 50% owned by an electric
utility or electric utility holding company. A QF that is a cogeneration
facility must produce not only electricity, but also useful thermal energy for
use in an industrial or commercial process or heating or cooling applications in
certain proportions to the facility's total energy output, and it must meet
certain energy efficiency standards. Therefore, loss of a thermal energy
customer could jeopardize a cogeneration facility's QF status. All geothermal
power plants up to 80 megawatts that meet PURPA's ownership requirements and
certain other standards are considered QFs. If one of the power plants in which
the Company has an interest were to lose its QF status and not otherwise receive
a PUHCA exemption, the project subsidiary or partnership in which the Company
has an interest owning or leasing that plant could become a public utility
company, which could subject the Company to significant federal, state and local
laws, including rate regulation and regulation as a public utility holding
company under PUHCA. This loss of QF status, which may be prospective or
retroactive, in turn, could cause all of the Company's other power plants to
lose QF status because, under FERC regulations, a QF cannot be owned by an
electric utility or electric utility holding company. In addition, a loss of QF
status could, depending on the power sales agreement, allow the power purchaser
to cease taking and paying for electricity or to seek refunds of past amounts
paid and thus could cause the loss of some or all contract revenues or otherwise
impair the value of a project and could trigger defaults under provisions of the
applicable project contracts and financing agreements (rendering such debt
immediately due and payable). If a power purchaser ceased taking and paying for
electricity or sought to obtain refunds of past amounts paid, there can be no
assurance that the costs incurred in connection with the project could be
recovered through sales to other purchasers.

39
42

Currently, Congress is considering proposed legislation that would amend
PURPA by eliminating the requirement that utilities purchase electricity from
QFs at avoided costs. The Company does not know whether such legislation will be
passed or what form it may take. The Company believes that if any such
legislation is passed, it would apply to new projects. As a result, although
such legislation may adversely affect the Company's ability to develop new
projects, the Company believes it would not affect the Company's existing QFs.
There can be no assurance, however, that any legislation passed would not
adversely impact the Company's existing projects.

Many states are implementing or considering regulatory initiatives designed
to increase competition in the domestic power generation industry. In a December
20, 1995 policy decision, the CPUC outlined a new market structure that would
provide for a competitive power generation industry and direct access to
generation for all consumers within five years. The CPUC has issued decisions
which provide for direct access for all customers beginning April 1, 1998, and
the unbundling of all electric services. As part of its policy decision, the
CPUC indicated that power sales agreements of existing QFs would be honored. The
Company cannot predict the final form or timing of the proposed restructuring
and the impact, if any, that such restructuring would have on the Company's
existing business or results of operations.

SEISMIC DISTURBANCES

Areas in which the Company operates and is developing many of its
geothermal and gas-fired projects are subject to frequent low-level seismic
disturbances, and more significant seismic disturbances are possible. While the
Company's existing power generation facilities are built to withstand relatively
significant levels of seismic disturbances, and the Company believes it
maintains adequate insurance protection, 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 continue to be available to the Company
on commercially reasonable terms.

AVAILABILITY OF NATURAL GAS

To date, the Company's fuel acquisition strategy has included various
combinations of Company-owned gas reserves, gas prepayment contracts and short,
medium and long-term supply contracts. In its gas supply arrangements, the
Company attempts to match the fuel cost with the fuel component included in the
facility's power sales agreements, in order to minimize a project's exposure to
fuel price risk. The Company believes that there will be adequate supplies of
natural gas available at reasonable prices for each of its facilities when
current gas supply agreements expire. There can be no assurance, however, that
gas supplies will be available for the full term of the facilities' power sales
agreements, or that gas prices will not increase significantly. If gas is not
available, or if gas prices increase above the fuel component of the facilities'
power sales agreements, there could be a material adverse impact on the
Company's results of operations.

COMPETITION

The power generation industry is characterized by intense competition, and
the Company encounters competition from utilities, industrial companies and
other power producers. In recent years, there has been increasing competition in
an effort to obtain power sales agreements, and this competition has contributed
to a reduction in electricity prices. In addition, many states are implementing
or considering regulatory initiatives designed to increase competition in the
domestic power industry. In California, the CPUC has issued decisions which
provide for direct access for all customers beginning April 1, 1998. Regulatory
initiatives are also being considered in other states, including Texas, New York
and states in New England. This competition has put pressure on electric
utilities to lower their costs, including the cost of purchased electricity, and
increasing competition in the future will increase this pressure.

40
43

DEPENDENCE ON SENIOR MANAGEMENT

The Company's success is largely dependent on the skills, experience and
efforts of its senior management. The loss of the services of one or more
members of the Company's senior management could have a material adverse effect
on the Company's business and development. To date, the Company generally has
been successful in retaining the services of its senior management.

QUARTERLY FLUCTUATIONS; SEASONALITY

The Company's quarterly operating results have fluctuated in the past and
may continue to do so in the future as a result of a number of factors,
including but not limited to the timing and size of acquisitions, the completion
of development projects, the timing and amount of curtailment, if any, and
variations in levels of production. Furthermore, the majority of capacity
payments under certain of the Company's power sales agreements are received
during the months of May through October.

EMPLOYEES

As of December 31, 1997, the Company employed 356 people. None of the
Company's employees are covered by collective bargaining agreements, and the
Company has never experienced a work stoppage, strike or labor dispute. The
Company considers relations with its employees to be good.

ITEM 2. PROPERTIES

The Company's principal executive office is located in San Jose, California
under a lease that expires in June 2001.

The Company, through its ownership of CGC and TPC, has leasehold interests
in 109 leases comprising 27,263 acres of federal, state and private geothermal
resource lands in The Geysers area in northern California. These leases comprise
its West Ford Flat Power Plant, Bear Canyon Power Plant, PG&E Unit 13 and Unit
16 Steam Fields, SMUDGEO #1 Steam Fields TPC's 25% undivided interest in the TPC
Steam Fields which are operated by Union Oil. In the Glass Mountain and Medicine
Lake areas in northern California, the Company holds leasehold interests in 18
leases comprising approximately 25,028 acres of federal geothermal resource
lands.

In general, under the leases, the Company has the exclusive right to drill
for, produce and sell geothermal resources from these properties and the right
to use the surface for all related purposes. Each lease requires the payment of
annual rent until commercial quantities of geothermal resources are established.
After such time, the leases require the payment of minimum advance royalties or
other payments until production commences, at which time production royalties
are payable. Such royalties and other payments are payable to landowners, state
and federal agencies and others, and vary widely as to the particular lease. The
leases are generally for initial terms varying from 10 to 20 years or for so
long as geothermal resources are produced and sold. Certain of the leases
contain drilling or other exploratory work requirements. In certain cases, if a
requirement is not fulfilled, the lease may be terminated and in other cases
additional payments may be required. The Company believes that its leases are
valid and that it has complied with all the requirements and conditions material
to their continued effectiveness. A number of the Company's leases for
undeveloped properties may expire in any given year. Before leases expire, the
Company performs geological evaluations in an effort to determine the resource
potential of the underlying properties. No assurance can be given that the
Company will decide to renew any expiring leases.

The Company, through its ownership of the Greenleaf 1 Power Plant, owns 77
acres in Sutter County, California.

The Company owns the Calpine Gas Company, which includes 112 leases
covering approximately 16,094 gross acres and 15,037 net acres. The Company
believes that its properties are adequate for its current operations.

ITEM 3. LEGAL PROCEEDINGS

On September 30, 1997, a lawsuit was filed by Indeck North American Power
Fund ("Indeck") in the Circuit Court of Cook County, Illinois against Norweb
plc. and certain other parties, including the Company. Some of Indeck's claims
relate to Calpine Gordonsville, Inc.'s acquisition of a 50% interest in
Gordonsville Energy L.P. from Northern Hydro Limited and Calpine Auburndale,
Inc.'s acquisition of a 50% interest in Auburndale Power Partners Limited
Partnership from Norweb Power Services (No. 1) Limited. Indeck is claiming that
Calpine Gordonsville, Inc., Calpine Auburndale, Inc. and the Company tortiously
interfered with Indeck's contractual rights to purchase such interests and
conspired with other parties to do so. Indeck is seeking $25.0 million in
compensatory damages, $25.0 million in punitive damages, and the recovery of
attorneys' fees and costs. All of the defendants have filed motions to dismiss
such claims, which are currently pending. The Company believes that the claims
of Indeck are without merit and that the resolution of this matter will not have
a material adverse effect on the Company's financial position or results of
operations.

On February 17, 1998, the Company filed an action in the Superior Court of
California, Sonoma County, seeking injunctive and declaratory relief to prevent
PG&E from unilaterally assigning the Company's steam sales contract to the
prospective winning bidder in PG&E's recently announced auction of its power
plants in The Geysers. On January 14, 1998, PG&E filed an application with the
CPUC pursuant to Public Utilities Code Section 851 ("851 Filing"), in which it
seeks authorization to sell five electric generating plants and related assets.
Included in this proposed sale are The Geysers Geothermal Power Plants
(including Units 13 and 16) and certain of PG&E's fossil fueled steam-electric
generating plants. In PG&E's 851 Filing, PG&E announced its intention to assign
its rights and to delegate its duties under the Company's steam contract to the
successful third party purchaser of the Unit 13 and Unit 16 Power Plants. The
Company has been informed by PG&E that it will attempt to make such assignment
and delegation without first seeking and obtaining the approval and consent of
the Company. The Company is challenging the continued validity of the price term
of the steam sales contract following the proposed divestiture by PG&E of 98% of
its fossil fueled steam-electric generating plants, as the price term of the
steam sales contract is based on a complex formula that reflects PG&E's weighted
average cost of fossil and nuclear fuel from the preceding year.

In a related action, the Company has filed a protest with the CPUC which
raises issues similar to those addressed in the above-referenced lawsuit and, in
addition, challenges certain inaccuracies contained in portions of PG&E's 851
Filings related to Unit 13 and Unit 16. As no discovery has been conducted in
either matter, nor has any answer been filed in the lawsuit, the Company is
unable to predict the outcome of these cases.

An action was filed against Lockport Energy Associates, L.P. ("LEA") on
August 7, 1997 by New York State Electricity and Gas Company ("NYSEG") in the
Federal District Court for the Northern District of New York. NYSEG has
requested the Court to direct the Federal Energy Regulatory Commission (the
"FERC") and the New York Public Service Commission ("NYPSC"), to modify contract
rates to be paid to the Lockport Power Plant. On October 14, 1997, NYPSC, a
named defendant in the NYSEG action, filed a cross-claim alleging that the FERC
violated PURPA and the Federal Power Act by failing to reform the NYSEG contract
which was previously approved by the NYPSC. LEA continues to vigorously defend
this action, although it is unable to predict the outcome of this case. The
Company retains the right to require The Brooklyn Union Gas Company ("BUG") to
purchase the Company's interest in the Lockport Power Plant for $18.9 million,
less equity distributions received by the Company, at any time before December
19, 2001. In the event the NYSEG's action is successful, the Company may choose
to exercise its right to require BUG to purchase its interest in the Lockport
Power Plant.

There is currently a dispute between Texas-New Mexico Power Company ("TNP")
and Clear Lake Cogeneration Limited Partnership ("CLC"), which owns the Clear
Lake Power Plant, regarding certain costs and other amounts that TNP has
withheld from payments due under the power sales agreement. As of December 31,
1997, TNP has withheld approximately $5.4 million related to transmission
charges and has continued to withhold approximately $450,000 per month
thereafter. CLC filed a petition for declaratory order with the Texas Public
Utilities Commission ("Texas PUC") on October 2, 1997 requesting that the Texas
PUC declare that TNP's

42
45

withholding is in error. This matter is pending before the Texas PUC. In
addition, as of December 31, 1997, TNP has withheld approximately $4.4 million
of standby power charges and has continued to withhold approximately $270,000
per month thereafter. CLC has filed a lawsuit in Texas against TNP claiming that
TNP is in breach of certain provisions of the power sales agreement, including
the provisions involved in the disputes described above, and is seeking in
excess of $15.0 million in damages. A trial is scheduled to begin on June 1,
1998. The Company is unable to predict the outcome of either of these
proceedings.

The Company is involved in various other claims and legal actions arising
out of the normal course of business. The Company does not expect that the
outcome of these proceedings will have a material adverse effect on the
Company's financial position or results of operations, although no assurance can
be given in this regard.

(1) In 1997, the Company adopted Statement of Financial Accounting Standards
("SFAS") No. 128, "Earnings per Share," and subsequently, in February 1998,
Staff Accounting Bulletin ("SAB") No. 98 on Computations of Earnings per
Share. In accordance with SFAS No. 128, basic earnings per common share for
all periods was computed by dividing net income by the weighted average
shares of common stock outstanding during the year. Diluted earnings per
common share for all periods was also computed in conformance with SFAS No.
128 by dividing net income by the weighted average shares of common stock
outstanding during the year and the additional number of shares that would
have been outstanding during the year if the Company's dilutive potential
shares had been issued. The treasury stock method was used to calculate the
potential number of dilutive shares associated with the Company's
outstanding stock options (see Note 2 of Notes to Consolidated Financial
Statements).

(2) EBITDA is defined as income from operations plus depreciation, capitalized
interest, other income, non-cash charges and cash received from investments
in power projects, reduced by the income from unconsolidated investments in
power projects. EBITDA is presented 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 to either (i) income from
operations (determined in accordance with generally accepted accounting
principles) or (ii) cash flows from operating activities (determined in
accordance with generally accepted accounting principles).

(3) Consolidated Interest Expense is defined as total interest expense plus
one-third of all operating lease obligations, capitalized interest,
dividends paid in respect of preferred stock and cash contributions to any
employee stock ownership plan used to pay interest on loans incurred to
purchase capital stock of the Company.

(4) Earnings are defined as income before provision for taxes, extraordinary
item and cumulative effect of change in accounting principle plus cash
received from investments in power projects and fixed charges reduced by the
equity in income from investments in power projects and capitalized
interest. Fixed charges consist of interest expense, capitalized interest,
amortization of debt issuance costs and the portion of rental expenses
representative of the interest expense component.

megawatt gas-fired power plant currently under construction in Dighton,
Massachusetts. Since its inception in 1984, the Company has developed
substantial expertise in all aspects of electric power generation. The Company's
vertical integration has resulted in significant growth in recent years as the
Company has applied its extensive engineering, construction management,
operations, fuel management and financing capabilities to successfully implement
its acquisition and development program. The Company's strategy is to capitalize
on opportunities in the power market through an ongoing program to acquire,
develop, own and operate electric power generation facilities, as well as
marketing power and energy services to utilities and other end users.

The Company's net interest in power generation facilities has increased
from 297 megawatts in 1992 to 1981 megawatts at December 31, 1997, including the
power plants currently under construction. Total assets have increased from
$55.4 million as of December 31, 1992 to $1.4 billion as of December 31, 1997.
The Company's revenue has increased to $276.3 million for 1997, representing a
5-year compound annual growth rate of 48% since 1992. The Company's EBITDA (see
Selected Consolidated Financial Data) for 1997 increased to $172.6 million from
$9.9 million in 1992, representing a 5-year compound annual growth rate of 77%.

In January 1995, the Company purchased the working interest in certain of
the geothermal properties at the Pacific Gas & Electric Company ("PG&E") Unit 13
and Unit 16 Steam Fields from a third party for a purchase price of $6.75
million. On April 21, 1995, the Company acquired the stock of certain companies
that own 100% of the Greenleaf 1 and 2 Power Plants, consisting of two 49.5
megawatt gas-fired cogeneration facilities, for an adjusted purchase price of
$81.5 million. On June 29, 1995, the Company acquired the operating lease for
the Watsonville Power Plant, a 28.5 megawatt gas-fired cogeneration facility,
for a

F-4
58

purchase price of $900,000. On November 17, 1995, the Company entered into a
series of agreements to invest up to $20.0 million in the Cerro Prieto Steam
Fields.

In April 1996, the Company entered into a lease transaction for the King
City Power Plant, a 120 megawatt gas-fired cogeneration facility, which required
an investment of $108.3 million, primarily related to the collateral fund
requirements. On August 29, 1996, the Company acquired the Gilroy Power Plant, a
120 megawatt gas-fired cogeneration facility, for a purchase price of $125.0
million plus certain contingent consideration, which the Company currently
estimates will amount to approximately $24.1 million, of which $12.5 million has
been paid as of December 31, 1997.

On January 31, 1997, the Company paid approximately $7.1 million to acquire
the stock of Montis Niger, Inc. (subsequently renamed Calpine Gas Company).
Calpine Gas Company has 8.1 billion cubic feet of estimated proven gas reserves
and an 80-mile pipeline system which provide gas to the Company's Greenleaf 1
and 2 Power Plants.

In February 1997, the Company commenced construction of the Pasadena Power
Plant, a 240 megawatt gas-fired cogeneration facility at the Phillips Houston
Chemical Complex ("HCC") located in Pasadena, Texas. The Company has entered
into an agreement to supply HCC with approximately 90 megawatts of electricity
(see Note 3 of Notes to Consolidated Financial Statements), with the remainder
of available electricity output to be sold into the competitive market. The
Pasadena Power Plant is the first merchant power plant to be financed with
non-recourse project financing and is scheduled to be operational in July 1998.

On June 23, 1997, the Company completed the acquisition of a 50% equity
interest in two gas-fired cogeneration facilities, the 450 megawatt Texas City
Power Plant and the 377 megawatt Clear Lake Power Plant, for an aggregate
purchase price of $35.4 million. As a part of that acquisition, the Company
entered into a $125.0 million non-recourse project financing agreement with The
Bank of Nova Scotia, the proceeds of which were utilized for the acquisition of
the 50% equity interest and the purchase of $155.6 million of outstanding
non-recourse project financing associated with the Texas City and Clear Lake
Power Plants.

On October 9, 1997, the Company completed the acquisition of 50% interests
in the Gordonsville Power Plant, a 240 megawatt gas-fired cogeneration facility
located in Gordonsville, Virginia, and the Auburndale Power Plant, a 150
megawatt gas-fired cogeneration facility located in Auburndale, Florida, for an
aggregate purchase price of $42.4 million.

On October 10, 1997, the Company entered into agreements with Energy
Management Inc. to invest in the development of two merchant power plants,
including the 169 megawatt gas-fired combined-cycle Dighton Power Plant to be
located in Dighton, Massachusetts, and the 265 megawatt gas-fired combined-cycle
Tiverton Power Plant to be located in Tiverton, Rhode Island. In October 1997,
the Company invested $16.0 million in the Dighton Power Plant (see Note 3 of
Notes to Consolidated Financial Statements). The Company intends to invest up to
$42.0 million of equity in the development of the Tiverton Power Plant. There
can be no assurances that the Dighton or Tiverton Power Plants will be
successfully developed.

On December 19, 1997, the Company completed the acquisition of 100% of the
capital stock of Gas Energy, Inc. ("GEI") and Gas Energy Cogeneration Inc.
("GECI") from The Brooklyn Union Gas Company for an aggregate purchase price of
$100.9 million, subject to final adjustments. GEI and GECI indirectly own (i) a
50% general partnership interest in the Kennedy International Airport Power
Plant, a 107 megawatt gas-fired cogeneration facility located at the John F.
Kennedy International Airport in Queens, New York, (ii) a 50% general
partnership interest in the Stony Brook Power Plant, a 40 megawatt gas-fired
cogeneration facility located on the campus of the State University of New York
in Stony Brook, New York, (iii) a 45% general partnership interest in the
Bethpage Power Plant, a 57 megawatt gas-fired cogeneration facility located in
Bethpage, New York, (iv) an 11.36% limited partnership interest in the Lockport
Power Plant, a 184 megawatt gas-fired cogeneration facility located in Lockport,
New York, and (v) a 100% interest in three fuel management contracts.

On February 5, 1998, the Company acquired the remaining 55% interest in,
and assumed operations and maintenance of, the Bethpage Power Plant. The Company
purchased the remaining interests for approximately $4.6 million.

59

On February 18, 1998, the Company announced that it had entered into
exclusive negotiations to acquire a 70 megawatt gas-fired power plant and
natural gas pipeline system from The Dow Chemical Company located in Pittsburg,
California. There can be no assurance that the Company will successfully
complete this acquisition.

Each of the Company's power plants produces electricity for sale to a
utility or other third party purchasers. Thermal energy produced by the
gas-fired cogeneration facilities is sold to governmental and industrial users,
and steam produced by the geothermal steam fields is sold to utility-owned power
plants. The electricity, thermal energy and steam generated by these facilities
are typically sold pursuant to long-term, take-and-pay power or steam sales
agreements, generally having original terms of 20 or 30 years.

PG&E pays a fixed price for each unit of electrical energy according to
schedules set forth in the long-term power sales agreements for Bear Canyon (20
megawatts) and West Ford Flat (27 megawatts) Power Plants. The fixed price
periods under these power sales agreements expire in September and December
1998, respectively. After the fixed price periods expire, while the basis for
the capacity and capacity bonus payments under these power sales agreements
remains the same, the energy payments adjust to interim short-run avoided cost
("SRAC"), which is calculated pursuant to the methodology approved by the
California Public Utilities Commission ("CPUC") on December 9, 1996, and will
continue at SRAC until the independent power exchange has commenced operations
and is functioning properly. The independent power exchange is currently
scheduled to commence operations on April 1, 1998. Thereafter, SRAC will
eventually become the energy-clearing price of the independent power exchange.
During 1997, SRAC averaged approximately 2.94c per kilowatt-hour. As a result,
while SRAC does not affect capacity payments under the power sales agreements,
the Company's energy revenue under these power sales agreements is expected to
be materially reduced at the expiration of the fixed price period. Such
reduction may have a material adverse effect on the Company's results of
operations. The Company expects the forecasted decline in energy revenues will
be mitigated by decreased royalty expenses and planned operating cost reductions
at the facilities. The Company expects to continue its strategy of replacing
decreased revenues through its acquisition and development program. In addition,
prices paid for the steam delivered by the Company's steam fields are based on a
formula that partially reflects the price levels of nuclear and fossil fuels,
and, therefore, a reduction in the price levels of such fuels may reduce revenue
under the steam sales agreements for the steam fields.

Certain of the Company's power and steam sales agreements contain
curtailment provisions under which the purchasers of energy or steam are
entitled to reduce the number of hours of energy or amount of steam purchased
thereunder. For the year ended December 31, 1996, certain of the Company's power
generation facilities experienced maximum curtailment primarily as a result of
low gas prices and a high degree of precipitation during the period, which
resulted in high levels of energy generation by hydroelectric power plants that
supply electricity. For the year ended December 31, 1997, such plants
experienced a reduced amount of curtailment compared to the same period in 1996.
Due to an amendment to certain of the power sales agreements executed in May
1997, the Company currently does not expect curtailment during the remainder of
the terms of the power sales agreements for these power plants.

Many states are implementing or considering regulatory initiatives designed
to increase competition in the domestic power generation industry. In December
1995, the CPUC issued an electric industry restructuring decision, which
envisioned commencement of deregulation and implementation of customer choice of
electricity supplier by January 1, 1998. Legislation implementing this decision
was adopted in September 1996. The CPUC subsequently extended the implementation
date to April 1, 1998. As part of its policy decision, the CPUC indicated that
power sales agreements of existing qualifying facilities would be honored. The
Company cannot predict the final form or timing of the proposed restructuring
and the impact, if any, that such restructuring would have on the Company's
existing business or results of operations. The Company believes that any such
restructuring would not have a material effect on its power sales agreements
and, accordingly, believes that its existing business and results of operations
would not be materially adversely affected, although there can be no assurance
in this regard.

SELECTED OPERATING INFORMATION

Set forth below is certain selected operating information for the power
plants and steam fields, for which results are consolidated in the Company's
Consolidated Statements of Operations. The information set forth under power
plants consists of the results for the West Ford Flat Power Plant, the Bear
Canyon Power Plant, the Greenleaf 1 and 2 Power Plants since their acquisitions
on April 21, 1995, the Watsonville Power Plant since the acquisition of the
lease on June 29, 1995, the King City Power Plant since the effective date of
the lease on May 2, 1996, and the Gilroy Power Plant since its acquisition on
August 29, 1996. The information set forth under steam fields consists of the
results for the PG&E Unit 13 and Unit 16 Steam Fields, the SMUDGEO #1 Steam
Fields and, for 1994 through 1997, the Thermal Power Company Steam Fields since
the acquisition of Thermal Power Company ("TPC") on September 9, 1994. The
information provided for the other interest included under steam revenue prior
to 1995 represents revenue attributable to a working interest that was held by a
third party in the PG&E Unit 13 and Unit 16 Steam Fields. In January 1995, the
Company purchased this working interest. Prior to the Company's acquisition of
the remaining interest in the Bear Canyon and West Ford Flat Power Plants, the
PG&E Unit 13 and Unit 16 Steam Fields and the SMUDGEO #1 Steam Fields on April
19, 1993, the Company's revenue from these facilities was accounted for under
the equity method and, therefore, does not represent the actual revenue of the
Company from these facilities for the periods set forth below.

related to production, and variable energy payments, which are related to
production.

(2) Represents variable energy revenue divided by the kilowatt-hours produced.
The significant increase in capacity revenue and the accompanying decline in
average energy price per kilowatt-hour since 1994 reflects the increase in
the Company's megawatt hour production as a result of acquisitions of
gas-fired power plants by the Company.

RESULTS OF OPERATIONS

YEAR ENDED DECEMBER 31, 1997 COMPARED TO YEAR ENDED DECEMBER 31, 1996

Revenue -- Total revenue increased 29% to $276.3 million in 1997 compared
to $214.6 million in 1996. Electricity and steam sales revenue increased 19% to
$237.3 million in 1997 compared to $199.5 million in 1996. Electricity and steam
sales revenue for 1997 reflected a full year of operation at the Gilroy and King
City Power Plants which contributed to increases in electricity and steam sales
revenue in 1997 compared to 1996 of $25.4 million, and $4.3 million,
respectively. Electricity and steam sales revenue for 1997 compared to 1996 was
also $6.0 million higher at the Bear Canyon and West Ford Flat Power Plants as a
result of increased production and an increase in fixed energy prices to 13.83c
per kilowatt-hour. During 1996, the Bear Canyon and West Ford Flat Power Plants
experienced the maximum curtailment allowed under their power sales agreements
with PG&E. In May 1997, the power sales agreements for the Bear Canyon and West
Ford Flat Power Plants were modified to remove curtailment. Without such
curtailment, these plants generated an

F-7
61

additional $4.2 million in revenues in 1997 as compared to 1996. In addition,
TPC also contributed $2.7 million more revenue for 1997 than 1996, primarily due
to increased steam sales under the alternative pricing agreement entered into
with PG&E in March 1996. Service contract revenue increased to $10.2 million in
1997 compared to $6.5 million in 1996. Service contract revenue during 1996
reflected a $2.8 million loss from the Company's electricity trading operations.
The increase in service contract revenue for 1997 was also attributable to $2.8
million of revenue from the Texas City and Clear Lake Power Plants, which were
acquired in June 1997. Income from unconsolidated investments in power projects
increased to $15.8 million in 1997 compared to $6.5 million during 1996. The
increase in 1997 compared to 1996 was primarily due to equity income of $6.3
million from the Company's June 1997 investment in the Texas City and Clear Lake
Power Plants (see Note 3 of Notes to Consolidated Financial Statements), and an
increase in equity income of $2.2 million from the Company's investment in Sumas
Cogeneration Company, L.P. ("Sumas") (see Note 5 of Notes to Consolidated
Financial Statements). In accordance with a power sales agreement with Puget
Sound Power and Light Company, operations at Sumas were significantly displaced
from February to July 1997, and, in exchange, the Sumas Power Plant received a
higher price for energy sold and certain other payments. In addition, the
partnership agreement governing Sumas was amended in September 1997 to increase
the Company's percentage of distributions. Interest income on loans to power
projects increased to $13.0 million in 1997 compared to $2.1 million in 1996.
The increase was primarily related to interest income on the loans made by
Calpine Finance Company, a wholly-owned subsidiary of the Company, to the Texas
City and Clear Lake Power Plants, and to interest income on the loans to the
sole shareholder of Sumas Energy, Inc., the Company's partner in Sumas (see Note
6 of Notes to Consolidated Financial Statements).

Cost of revenue -- Cost of revenue increased 19% to $153.3 million in 1997
compared to $129.2 million in 1996. Plant operating, depreciation, and operating
lease expenses at the Gilroy and King City Power Plants for 1997 reflected a
full year of operations, which contributed to increases in cost of revenue in
1997 compared to 1996 of $13.0 million and $8.3 million, respectively.

Project development expenses -- Project development expenses increased 92%
to $7.5 million in 1997 compared to $3.9 million in 1996, due primarily to
expanded acquisition and development activities.

General and administrative expenses -- General and administrative expenses
increased 24% to $18.3 million in 1997 compared to $14.7 million in 1996. The
increases were primarily due to additional personnel and related expenses
necessary to support the Company's expanding operations.

Interest expense -- Interest expense increased 36% to $61.5 million in 1997
from $45.3 million in 1996. The increase was attributable to: (i) $10.8 million
of interest expense related to the 8 3/4% Senior Notes Due 2007 issued in July
and September 1997, (ii) a $7.3 million increase in interest expense related to
the 10 1/2% Senior Notes Due 2006 issued May 1996, (iii) a $6.4 million increase
in interest expense on debt related to the Gilroy Power Plant acquired in August
1996 and (iv) $5.4 million of interest expense on debt related to the
acquisition of the Texas City and Clear Lake Power Plants. These increases were
offset by $6.2 million of interest capitalized for the development and
construction of power plants, and a $7.6 million decrease in interest expense at
Calpine Geysers Company, L.P. ("CGC") and TPC due to repayment of debt.

Interest income -- Interest income increased 66% to $14.3 million for 1997
compared with $8.6 million for 1996. Interest income earned on collateral
securities purchased in April 1996 in connection with the King City Power Plant
contributed to an increase in interest income of $1.2 million in 1997 as
compared to 1996. In addition, higher cash and cash equivalent balances
resulting from the issuance of the 8 3/4% Senior Notes Due 2007 during 1997
resulted in higher interest income for 1997 as compared to 1996.

Other income, net -- Other income, net, increased to $3.2 million for 1997
compared with expense of $2.3 million for 1996. In 1997, the Company recorded a
$1.1 million gain on the sale of a note receivable (see Note 6 of Notes to
Consolidated Financial Statements) and received a refund of $961,000 from PG&E.
In 1996, the Company recorded a $3.7 million loss for uncollectible amounts
related to an acquisition project.

Provision for income taxes -- The effective rate for the income tax
provision was approximately 35% in 1997 and 33% in 1996. The reductions from the
statutory tax rate were primarily due to depletion in excess of

F-8
62

tax basis benefits at the Company's geothermal facilities, a decrease in the
California taxes paid due to the Company's expansion into states other than
California, and a revision of prior years' tax estimates.

YEAR ENDED DECEMBER 31, 1996 COMPARED TO YEAR ENDED DECEMBER 31, 1995

Revenue -- Total revenue increased 62% to $214.6 million in 1996 compared
to $132.1 million in 1995. Electricity and steam sales revenue increased 56% to
$199.5 million in 1996 compared to $127.8 million in 1995. The King City and
Gilroy Power Plants contributed revenues of $41.5 million and $14.7 million,
respectively, to electricity and steam revenues during 1996. Revenue for 1996
also reflected a full year of operation at the Greenleaf 1 and 2 Power Plants
and the Watsonville Power Plant, which contributed to increases in electricity
and steam revenues in 1996 compared to 1995 of $9.1 million and $4.7 million,
respectively. During 1996 and 1995, the Company experienced the maximum
curtailment allowed under the power sales agreements with PG&E for the Bear
Canyon and West Ford Flat Power Plants. Without such curtailment, the Bear
Canyon and West Ford Flat Power Plants would have generated an additional $5.2
million and $5.7 million of revenue in 1996 and 1995, respectively. Service
contract revenue decreased to $6.5 million in 1996 compared to $7.2 million in
1995, reflecting a $2.8 million loss related to the Company's electricity
trading operations, offset by increased revenue during 1996 related to overhauls
at the Aidlin and Agnews Power Plants, and to technical services performed for
the Cerro Prieto project. Income from unconsolidated investments in power
projects increased to $6.5 million in 1996 compared to losses of $2.9 million
during 1995. The increase is primarily attributable to $6.4 million of equity
income generated by the Company's investment in Sumas during 1996 compared to a
$3.0 million loss in 1995. The increase in Sumas' profitability during 1996 is
primarily attributable to a contractual increase in the energy price in
accordance with the power sales agreement with Puget Sound Power & Light
Company. Interest income on loans to power projects was $2.1 million in 1996 as
a result of the recognition of interest income on loans to the sole shareholder
of the general partner in Sumas.

Cost of revenue -- Cost of revenue increased 67% to $129.2 million in 1996
as compared to $77.4 million in 1995. The increase was primarily due to plant
operating, depreciation, and operating lease expenses attributable to: (i) a
full year of operation during 1996 at the Greenleaf 1 and 2 Power Plants, which
were purchased on April 21, 1995, (ii) a full year of operation during 1996 at
the Watsonville Power Plant, for which the Company acquired the operating lease
on June 29, 1995, (iii) operations at the King City Power Plant subsequent to
May 2, 1996, and (iv) operations at the Gilroy Power Plant subsequent to
acquisition on August 29, 1996. Cost of revenue also increased due to service
contract expenses related to the Cerro Prieto Steam Fields, partially offset by
lower operating expenses at the Company's other existing power generation
facilities and steam fields.

Project development expenses -- Project development expenses increased to
$3.9 million in 1996 compared to $3.1 million in 1995, due to project
development activities.

General and administrative expenses -- General and administrative expenses
were $14.7 million in 1996 compared to $8.9 million in 1995. The increases were
primarily due to additional personnel and related expenses necessary to support
the Company's expanding operations, including the Company's power marketing
operations. The Company also incurred an employee bonus expense of $1.4 million
in September 1996 related to the initial public offering.

Interest expense -- Interest expense increased 41% to $45.3 million in 1996
from $32.2 million in 1995. Approximately $11.8 million of the increase was
attributable to interest on the Company's 10 1/2% Senior Notes Due 2006 issued
in May 1996, $2.7 million of interest expense related to the Gilroy Power Plant
acquired on August 29, 1996, and $1.6 million of higher interest expense related
to the Greenleaf 1 and 2 Power Plants acquired on April 21, 1995, offset in part
by a $3.0 million decrease in interest expense as a result of repayments of
principal on certain non-recourse project financing.

Interest income -- Interest income increased to $8.6 million for 1996
compared with $1.6 million for 1995. The increase was primarily due to $4.5
million of interest income on collateral securities purchased in connection with
the acquisition of the King City operating lease, and higher interest income for
the period due to increased cash balances as a result of sales of equity and
debt securities.

F-9
63

Other income, net -- Other income, net decreased to $2.3 million of expense
for 1996 compared with $340,000 of income for 1995. The decrease was primarily
due to a $3.7 million loss for a dispute related to uncollectible amounts from
an acquisition project offset by $1.4 million in net proceeds from a development
project settlement.

Provision for income taxes -- The effective rate for the income tax
provision was approximately 33% in 1996 and 41% in 1995. In 1996, the Company
decreased its deferred income tax liability by $769,000 to reflect the change in
California's state income tax rate from 9.3% to 8.8% effective January 1, 1997.
In addition, depletion in excess of tax basis benefits at the Company's
geothermal facilities and a revision of prior years' tax estimates reduced the
Company's effective tax rate for 1996.

LIQUIDITY AND CAPITAL RESOURCES

To date, the Company has obtained cash from its operations, borrowings
under its credit facilities and other working capital lines, sale of debt and
equity, and proceeds from non-recourse project financing. The Company utilized
this cash to fund its operations, service debt obligations, fund the
acquisition, development and construction of power generation facilities,
finance capital expenditures and meet its other cash and liquidity needs.

The following table summarizes the Company's cash flow activities for the
periods indicated:

Operating activities in 1997 provided $108.5 million, consisting of
approximately $34.7 million of net income from operations, $46.8 million of
depreciation and amortization, $15.1 million of deferred income taxes, $23.0
million of distributions (see Note 5 of Notes to Consolidated Financial
Statements), and a $4.7 million net decrease in operating assets and
liabilities, offset by $15.8 million of income from unconsolidated investments
in power projects.

Investing activities used $402.2 million during 1997, primarily due to
$191.0 million for the acquisition of interests in the Texas City and Clear Lake
Power Plants and the related notes receivable, $100.9 million for the
acquisition of the capital stock of GEI and GECI, $42.4 million for the
acquisition of interests in the Auburndale and Gordonsville Power Plants, $16.0

expenditures related to the construction of the Pasadena Power Plant, $29.5
million of other capital expenditures, $6.2 million of interest capitalized on
construction projects, $6.0 million of capitalized project development costs,
offset by $200,000 of deferred project costs, $7.2 million of additional
investment in the Clear Lake Power Plant, $7.1 million for the acquisition of
Calpine Gas Company, offset by the receipt of $23.1 million of loan payments,
$10.0 million from the sale of loans (see Note 6 of Notes to Consolidated
Financial Statements), $5.4 million of maturities of collateral securities in
connection with the King City Power Plant and a $43.7 million decrease in
restricted cash, primarily related to the Pasadena Power Plant and CGC.

Financing activities provided $246.2 million of cash during 1997 consisting
of $125.0 million of borrowings for the acquisition of the interests in the
Texas City and Clear Lake Power Plants and the related notes receivable, $6.6
million of borrowings for contingent consideration in connection with the
acquisition of the Gilroy Power Plant and $275.0 million of proceeds from the
issuance of the 8 3/4% Senior Notes Due 2007, offset by $144.5 million in
repayment of non-recourse project financing, $7.1 million in repayment of notes
payable and $9.7 million of costs associated with financing activities.

F-10
64

At December 31, 1997, cash and cash equivalents were $48.5 million and
negative working capital was $12.0 million. For the twelve months ended December
31, 1997, cash and cash equivalents decreased by $47.5 million and working
capital decreased by $102.7 million as compared to December 31, 1996.

As a developer, owner and operator of power generation facilities, the
Company may be required to make long-term commitments and investments of
substantial capital for its projects. The Company historically has financed
these capital requirements with borrowings under its credit facilities, other
lines of credit, non-recourse project financing or long-term debt.

At December 31, 1997, the Company had $105.0 million of outstanding 9 1/4%
Senior Notes Due 2004, which mature on February 1, 2004 and bear interest
payable semi-annually on February 1 and August 1 of each year. In addition, the
Company had $180.0 million of outstanding 10 1/2% Senior Notes Due 2006, which
mature on May 15, 2006 and bear interest payable semi-annually on May 15 and
November 15 of each year. During 1997, the Company issued $275.0 million of
8 3/4% Senior Notes Due 2007, which mature on July 15, 2007 and bear interest
payable semi-annually on January 15 and July 15 of each year. Under the
provisions of the applicable indentures, the Company may, under certain
circumstances, be limited in its ability to make restricted payments, as
defined, which includes dividends and certain purchases and investments, incur
additional indebtedness and engage in certain transactions.

At December 31, 1997, the Company had $192.5 million of non-recourse
project financing associated with the Greenleaf 1 and 2 Power Plants and the
Gilroy Power Plant. The annual maturities for such non-recourse project
financing are $9.6 million for 1998, $8.7 million for 1999, $10.4 million for
2000, $10.6 million for 2001, $11.1 million for 2002 and $142.1 million
thereafter.

At December 31, 1997, the Company had $103.4 million of non-recourse
borrowings from The Bank of Nova Scotia in connection with the acquisition of
the notes receivable from the Texas City and Clear Lake Power Plants. Such
borrowings mature on June 22, 1998. The Company expects to refinance such
borrowings before the maturity date.

The Company currently has a $50.0 million revolving credit agreement with a
consortium of commercial lending institutions led by The Bank of Nova Scotia,
with borrowings bearing interest at either the London Inter Bank Offering Rate
or at The Bank of Nova Scotia base rate, plus a mutually agreed margin. At
December 31, 1997, the Company had no borrowings outstanding and $9.4 million of
letters of credit outstanding under the revolving credit facility (see Note 7 of
Notes to Consolidated Financial Statements). The Bank of Nova Scotia credit
facility contains certain restrictions that limit or prohibit, among other
things, the ability of the Company or its subsidiaries to incur indebtedness,
make payments of certain indebtedness, pay dividends, make investments, engage
in transactions with affiliates, create liens, sell assets and engage in mergers
and consolidations.

The Company has a $1.2 million working capital line with a commercial
lender that may be used to fund short-term working capital commitments and
letters of credit. At December 31, 1997, the Company had no borrowings under
this working capital line and $74,000 of letters of credit outstanding.
Borrowings are at prime plus 1%.

Where appropriate, the Company may use non-recourse project financing for
new projects. The debt agreements of the Company's subsidiaries and other
affiliates governing the non-recourse project financing generally restrict their
ability to pay dividends, make distributions or otherwise transfer funds to the
Company. The dividend restrictions in such agreements generally require that,
prior to the payment of dividends, distributions or other transfers, the
subsidiary or other affiliate must provide for the payment of other obligations,
including operating expenses, debt service and reserves. However, the Company
does not believe that such restrictions will adversely affect its ability to
meet its debt obligations.

At December 31, 1997, the Company had commitments for capital expenditures
in 1998 totaling $19.8 million related to the Pasadena Power Plant (see Note 3
of Notes to Consolidated Financial Statements). The Company intends to fund
capital expenditures for the ongoing operation and development of the Company's
power generation facilities primarily through the operating cash flow of such
facilities, non-recourse project financing and corporate financing. Capital
expenditures for the twelve months ended

F-11
65

December 31, 1997 of $107.1 million included $77.6 million for the construction
of the Pasadena Power Plant, $12.1 million related to the geothermal facilities,
$2.5 million related to the development of other merchant power plants and the
remaining $14.9 million at certain of the Company's gas-fired power plants.

The Company continues to pursue the acquisition and development of new
power plants. The Company expects to commit significant capital in future years
for the acquisition and development of these power plants. The Company's actual
capital expenditures may vary significantly during any year.

The Company believes that it will have sufficient liquidity from cash flow
from operations, borrowings available under the lines of credit, and working
capital to satisfy all obligations under outstanding indebtedness, to finance
anticipated capital expenditures and to fund working capital requirements
through December 31, 1998.

NEW ACCOUNTING STANDARDS

In June 1997, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards ("SFAS") No. 130, "Reporting
Comprehensive Income," which establishes standards for reporting comprehensive
income and its components (revenues, expenses, gains and losses) in financial
statements. SFAS No. 130 requires classification of other comprehensive income
in a financial statement, and the display of the accumulated balance of other
comprehensive income separately from retained earnings and additional paid-in
capital. SFAS No. 130 is effective for fiscal years beginning after December 15,
1997. The Company believes this pronouncement will not have a material effect on
its financial statements.

In June 1997, the FASB also issued SFAS No. 131, "Disclosures about
Segments of an Enterprise and Related Information," which established standards
for reporting information about operating segments in annual financial
statements and requires that enterprises report selected information about
operating segments in interim financial reports to shareholders. SFAS No. 131
also establishes standards for related disclosures about products and services,
geographic areas and major customers. SFAS No. 131 is effective for fiscal years
beginning after December 15, 1997, although earlier application is encouraged.
The Company believes this pronouncement will not have a material effect on its
financial statements.

YEAR 2000 COMPLIANCE

To ensure that the Company's computer systems are Year 2000 compliant, the
Company has begun preparing for the Year 2000 issue. The Company has been
reviewing each of its financial and operating systems to identify those that
contain two-digit year codes. The Company is assessing the amount of programming
required to upgrade or replace each of the affected programs with the goal of
completing all relevant internal software remediation and testing by 1998, with
continuing Year 2000 compliance efforts through 1999. In addition, the Company
is actively working with all of its partnerships to assess their compliance
efforts and the Company's exposure resulting from Year 2000 issues.

Based upon current information, the Company does not anticipate costs
associated with the Year 2000 issue to have a material financial impact.
However, there can be no assurances that there will not be interruptions or
other limitations of financial and operating systems functionality or that the
Company will not incur significant costs to avoid such interruptions or
limitations. The costs incurred relating to the Year 2000 issue will be expensed
by the Company during the period in which they are incurred. The Company's
expectations about future costs associated with the Year 2000 issue are subject
to uncertainties that could cause actual results to have a greater financial
impact than currently anticipated. Factors that could influence the amount and
timing of future costs include the success of the Company in identifying systems
and programs that contain two-digit year codes, the nature and amount of
programming required to upgrade or replace each of the affected programs, the
rate and magnitude of related labor and consulting costs, and the success of the
Company's partnerships in addressing the Year 2000 issue.

REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To The Board of Directors
of Calpine Corporation:

We have audited the accompanying consolidated balance sheets of Calpine
Corporation (a Delaware corporation) and subsidiaries as of December 31, 1997
and 1996, and the related consolidated statements of operations, stockholders'
equity and cash flows for each of the three years in the period ended December
31, 1997. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audits. We did not audit the financial statements of
Sumas Cogeneration Company, L.P. ("Sumas"), the investment in which is reflected
in the accompanying financial statements using the equity method of accounting.
The investment in Sumas represents approximately 1% of the Company's total
assets at December 31, 1996. There is no investment balance as of December 31,
1997. The Company has recorded income of $8.6 million and $6.4 million and
losses of $3.0 million representing its share of the net income or loss of Sumas
for the years ended December 31, 1997, 1996 and 1995, respectively. The
financial statements of Sumas were audited by other auditors whose report has
been furnished to us and our opinion, insofar as it relates to the amounts
included for Sumas, is based solely on the report of the other auditors.

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 and the report of the other auditors provide a
reasonable basis for our opinion.

In our opinion, based on our audits and the report of the other auditors,
the financial statements referred to above present fairly, in all material
respects, the financial position of Calpine Corporation and subsidiaries as of
December 31, 1997 and 1996, and the results of their operations and their cash
flows for each of the three years in the period ended December 31, 1997, in
conformity with generally accepted accounting principles.

CALPINE CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
FOR THE YEARS ENDED DECEMBER 31, 1997, 1996 AND 1995

1. ORGANIZATION AND OPERATIONS OF THE COMPANY

Calpine Corporation ("Calpine"), a Delaware corporation, and subsidiaries
(collectively, the "Company") is engaged in the development, acquisition,
ownership and operation of power generation facilities and the sale of
electricity and steam in the United States and selected international markets.
The Company has ownership interests in and operates gas-fired cogeneration
facilities, geothermal steam fields and geothermal power generation facilities
in northern California, Washington, Texas and various locations on the East
Coast. Each of the generation facilities produces and markets electricity for
sale to utilities and other third party purchasers. Thermal energy produced by
the gas-fired cogeneration facilities is primarily sold to governmental and
industrial users and steam produced by geothermal steam fields is sold to
utility-owned power plants. For the year ended December 31, 1997, primarily all
electricity and steam sales revenue from consolidated subsidiaries was derived
from sales to two customers in northern California (see Note 15), of which 43%
related to geothermal activities.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Principles of Consolidation -- The accompanying consolidated financial
statements include accounts of the Company. Wholly-owned and majority-owned
subsidiaries are consolidated. Less-than-majority-owned subsidiaries, and
subsidiaries for which control is deemed to be temporary, are accounted for
using the equity method. For equity method investments, the Company's share of
income is calculated according to the Company's equity ownership or according to
the terms of the appropriate partnership agreement (see Note 5). All significant
intercompany accounts and transactions are eliminated in consolidation. The
Company uses the proportionate consolidation method to account for Thermal Power
Company's ("TPC") 25% interest in jointly owned geothermal properties.

Use of Estimates in Preparation of Financial Statements -- The preparation
of financial statements in conformity with generally accepted accounting
principles requires management to make estimates and assumptions that affect the
reported amounts of assets and liabilities, and disclosure of contingent assets
and liabilities at the date of the financial statements and the reported amounts
of revenues and expenses during the reporting period. Actual results could
differ from those estimates. The most significant estimates with regard to these
financial statements relate to future development costs and total productive
resources of the geothermal facilities (see Property, Plant and Equipment), and
the realization of deferred income taxes (see Note 11). Additionally, the
Company believes that certain industry restructuring (see Note 16, Regulation
and CPUC Restructuring) will not have a material effect on existing power sales
agreements and, accordingly, will not have a material effect on existing
business or results of operations.

Revenue Recognition -- Revenue from electricity and steam sales is
recognized upon transmission to the customer. Revenues from contracts entered
into or acquired since May 21, 1992 are recognized at the lesser of amounts
billable under the contract or amounts recognizable at an average rate over the
term of the contract. The Company's power sales agreements related to Calpine
Geyser's Company, L.P. ("CGC") were entered into prior to May 1992. Had the
Company applied the methodology described above to the CGC power sales
agreements, the revenues recorded for the years ended December 31, 1997, 1996
and 1995, would have been approximately $20.1 million, $16.1 million, and $12.6
million less, respectively.

The Company performs operations and maintenance services for all
consolidated projects in which it has an interest, except for TPC. Revenue from
investees is recognized on these contracts when the services are performed.

Cash and Cash Equivalents -- The Company considers all highly liquid
investments with an original maturity of three months or less to be cash
equivalents. The carrying amount of these instruments approximates fair value
because of their short maturity.

CALPINE CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
FOR THE YEARS ENDED DECEMBER 31, 1997, 1996 AND 1995

Restricted Cash -- The Company is required to maintain cash balances that
are restricted by provisions of its debt agreements and by regulatory agencies.
The Company's debt agreements specify restrictions based on debt service
payments and drilling costs for the following year. Regulatory agencies require
cash to be restricted to ensure that funds will be available to restore property
to its original condition. Restricted cash is invested in accounts earning
market rates; therefore, the carrying value approximates fair value. Such cash
is excluded from cash and cash equivalents for the purposes of the consolidated
statements of cash flows.

Inventories -- Operating supplies are valued at the lower of cost or
market. Cost for large replacement parts is determined using the specific
identification method. For the remaining supplies, cost is determined using the
weighted average cost method.

Collateral Securities -- The Company maintains certain investments in
investment grade collateral securities which are classified as held-to-maturity
and stated at amortized cost. The investments in debt securities mature at
various dates through August 2018 in amounts equal to a portion of the King City
Power Plant lease payment (see Note 3, "King City Transaction"). The fair value

Concentration of Credit Risk -- Financial instruments which potentially
subject the Company to concentrations of credit risk consist primarily of cash,
accounts receivable, notes receivable, and loans receivable. The Company's cash
accounts are held by seven FDIC insured banks. The Company's accounts, notes and
loans receivable are concentrated within entities engaged in the energy industry
(see Note 15), mainly within the United States, some of which are related
parties. The Company also maintains a note receivable with a company in Mexico
(see Note 6, "Calpine Vapor Inc."). The Company generally does not require
collateral for accounts receivable.

Property, Plant and Equipment, net -- Property, plant and equipment, net
are stated at cost less accumulated depreciation and amortization.

The Company capitalizes costs incurred in connection with the development
of geothermal properties, including costs of drilling wells and overhead
directly related to development activities, together with the costs of
production equipment, the related facilities and the operating power plants.
Geothermal properties include the value attributable to the geothermal resources
of CGC and all of the property, plant and equipment of TPC. Proceeds from the
sale of geothermal properties are applied against capitalized costs, with no
gain or loss recognized. At December 31, 1997 and 1996, the Company had $4.0
million of geothermal leases at Glass Mountain in northern California recorded
as property, plant and equipment, net in the accompanying

F-19

FOR THE YEARS ENDED DECEMBER 31, 1997, 1996 AND 1995

consolidated balance sheets. The Company is continuing to pursue the development
of Glass Mountain, and expects to recover the cost of such leases from the
future development of the resource.

Geothermal costs, including an estimate of future development costs to be
incurred and the estimated costs to dismantle, are amortized by the units of
production method based on the estimated total productive output over the
estimated useful lives of the related steam fields. Depreciation of the
buildings and roads is computed using the straight-line method over their
estimated useful lives. It is reasonably possible that the estimate of useful
lives, total units of production or total capital costs to be amortized using
the units of production method could differ materially in the near term from the
amounts assumed in arriving at current depreciation expense. These estimates are
affected by such factors as the ability of the Company to continue selling steam
and electricity to customers at estimated prices, changes in prices of
alternative sources of energy such as hydro-generation and gas, and changes in
the regulatory environment.

Gas-fired power production facilities include the cogeneration plants and
related equipment and are stated at cost. Depreciation is recorded utilizing the
straight-line method over the estimated original useful life of up to 30 years.
The value of the above-market pricing provided in power sales agreements
acquired is recorded in property, plant and equipment, net and is amortized over
the above market pricing period in the power sales agreement with lives of 22
and 23 years. When assets are disposed of, the cost and related accumulated
depreciation are removed from the accounts, and the resulting gains or losses
are included in results of operations.

As of December 31, 1997 and 1996, the components of property, plant and
equipment, net are as follows (in thousands):

========= =========


Construction in progress includes costs primarily attributable to the
development and construction of the Pasadena Power Plant.

Project Development Costs -- The Company capitalizes project development
costs once it is determined that it is probable that such costs will be realized
through the ultimate construction of a power plant. Generally this occurs upon
the execution of a memorandum of understanding or a letter of intent for a power
or steam sales agreement. These costs include professional services, salaries,
permits and other costs directly related to the development of a new project.
Outside services and other third party costs are capitalized for acquisition
projects. Upon the start-up of plant operations or the completion of an
acquisition, these costs are generally transferred to property, plant and
equipment, net and amortized over the estimated useful life of the project.
Capitalized project costs are charged to expense when the Company determines
that the project will not be consummated or is impaired.

FOR THE YEARS ENDED DECEMBER 31, 1997, 1996 AND 1995

Capitalized Interest -- The Company capitalizes interest on projects during
the construction period. For the year ended December 31, 1997, the Company
capitalized $6.2 million of interest in connection with the construction of its
power plants. No interest was capitalized prior to 1997.

Other Assets -- Other assets consist of the following at December 31, (in
thousands):



1997 1996
------- -------

Deferred financing costs......................... $20,493 $13,396
Prepaid operating lease, long term portion....... 9,808 --
Other............................................ 507 121
------- -------
Other assets........................... $30,808 $13,517
======= =======


Deferred financing costs are amortized over the term of the related
financings, which range from 12 to 180 months.

Derivative Financial Instruments -- The Company engages in activities to
manage risks associated with changes in interest rates. The Company has entered
into swap agreements to reduce exposure to interest rate fluctuations in
connection with certain debt commitments. The instruments' cash flows mirror
those of the underlying exposure. Unrealized gains and losses relating to the
instruments are being deferred over the lives of the contracts. The premiums
paid on the instruments, as measured at inception, are being amortized over
their respective lives as components of interest expense. Any gains or losses
realized upon the early termination of these instruments are deferred and
recognized in income over the remaining life of the underlying exposure. At
December 31, 1997, the Company had $239.1 million of interest rate swaps on non-
recourse project financing.

Power Marketing -- The Company, through its wholly-owned subsidiary Calpine
Power Services Company ("CPSC"), markets power and energy services to utilities,
wholesalers, and end users. CPSC provides these services by entering into
contracts to purchase or supply electricity at specified delivery points and
specified future dates. In some cases, CPSC utilizes option agreements to manage
its exposure to market fluctuations. At December 31, 1997, CPSC held option
contracts with two entities for the purchase and sale of up to 50 megawatts each
for the period from June 1, 1998 to September 30, 1998.

Net open positions may exist due to the origination of new transactions and
the Company's evaluation of changing market conditions. An open position exposes
the Company to the risk that fluctuating market prices may adversely impact its
financial position or results of operations. However, any net open positions are
actively managed. The impact of such transactions on the Company's financial
position is not necessarily indicative of the impact of price fluctuations
throughout the year. CPSC values its portfolio using the aggregate lower of cost
or market method. An allowance is recorded for net aggregate losses of the
entire portfolio resulting from the effect of market changes on net open
positions. Net gains are recognized when realized.

The Company's credit risk associated with power contracts results from the
risk of loss as a result of non-performance by counter parties. The Company
reviews and assesses counter party risk to limit any material impact to its
financial position and results of operations. The Company does not anticipate
non-performance by the counter parties. The Company sets credit limits prior to
entering into transactions and has not obtained collateral or security.

Basic and Diluted Earnings Per Share -- In 1997, the Company adopted
Statement of Financial Accounting Standards ("SFAS") No. 128, "Earnings per
Share." In February 1998, the Securities and Exchange Commission ("SEC") staff
released Staff Accounting Bulletin ("SAB") No. 98, "Computations of Earnings per
Share." SAB No. 98 revises prior SEC guidance concerning presentation of
earnings per share information for companies going public, and requires all
companies to present earnings per share for all periods

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
FOR THE YEARS ENDED DECEMBER 31, 1997, 1996 AND 1995

for which income statement information is presented in accordance with SFAS No.
128. Basic earnings per share were computed using the weighted average number of
common shares outstanding. Diluted earnings per share were computed using the
weighted average number of common shares and the common equivalent shares that
would have been outstanding if the Company's dilutive potential shares had been
issued. The treasury stock method was used to calculate the potential number of
dilutive shares associated with the Company's outstanding stock options.

New Accounting Pronouncements -- In June 1997, the Financial Accounting
Standards Board ("FASB") issued SFAS No. 130, "Reporting Comprehensive Income,"
which establishes standards for reporting comprehensive income and its
components (revenues, expenses, gains and losses) in financial statements. SFAS
No. 130 requires classification of other comprehensive income in a financial
statement, and the display of the accumulated balance of other comprehensive
income separately from retained earnings and additional paid-in capital. SFAS
No. 130 is effective for fiscal years beginning after December 15, 1997. The
Company believes this pronouncement will not have a material effect on its
financial statements.

In June 1997, the FASB also issued SFAS No. 131, "Disclosures about
Segments of an Enterprise and Related Information." This pronouncement
established standards for reporting information about operating segments in
annual financial statements and requires that enterprises report selected
information about operating segments in interim financial reports to
shareholders. SFAS No. 131 also establishes standards for related disclosures
about products and services, geographic areas and major customers. SFAS No. 131
is effective for fiscal years beginning after December 15, 1997, although
earlier application is encouraged. The Company believes this pronouncement will
not have a material effect on its financial statements.

Reclassifications -- Certain prior years' amounts in the consolidated
financial statements have been reclassified where necessary to conform to the
1997 presentation.

The Company received $20.3 million and $1.3 million in distributions from
Sumas for the years ended December 31, 1997 and 1996, respectively. The Company
received $767,000 in distributions from Lockport Energy Associates, L.P. for the
year ended December 31, 1997.
- ---------------

(1) On September 30, 1997, the partnership agreement governing Sumas
Cogeneration Company, L.P. ("Sumas") was amended changing the distribution
percentages to the partners. As provided for in the amendment, the Company's
percentage share of the project's cash flow increased from 50% to
approximately 70% through June 30, 2001, based on certain specified
payments. Thereafter, the Company will receive 50% of the project's cash
flow until a 24.5% pre-tax rate of return on its original investment is
achieved, at which time the Company's equity interest in the partnership
will be reduced to 0.1%. As a result of the amendment of the partnership
agreement and the receipt of certain distributions during 1997, the
Company's investment in Sumas was reduced to zero. Because the investment
has been reduced to zero and there are no continuing obligations of the
Company related to Sumas, the Company expects that income recorded in future
periods will approximate the amount of cash received from partnership
distributions.

6. NOTES AND LOANS RECEIVABLE

SUMAS POWER PLANT

In May 1993, in accordance with the Sumas partnership agreement, the
Company was entitled to receive a distribution of $1.5 million and Sumas Energy,
Inc. ("SEI"), the Company's partner in Sumas, was required to make a capital
contribution of $1.5 million. In order to meet SEI's $1.5 million capital
contribution requirement, the Company loaned $1.5 million to the sole
shareholder of SEI, who in turn loaned the funds to SEI, who in turn contributed
the capital to Sumas. The interest rate on the loan was 20% and was secured by a
security interest in the loan between SEI and its sole shareholder. The Company
received all principal plus accrued interest totaling $2.8 million in 1997.

In March 1994, the Company loaned $10.0 million to the sole shareholder of
SEI. The interest rate on the loan was 16.25%. The loan was secured by a pledge
to Calpine of SEI's interest in Sumas. The Company deferred the recognition of
interest income from these notes until Sumas generated net income.

During 1997, the $10.0 million loan was sold to a third party. The Company
received all unpaid principal and interest related to both loans and recognized
a total of $6.9 million of the interest income during 1997 (of which $3.5
million was previously deferred). In addition, the Company recorded a $1.1
million gain upon the sale of the $10.0 million loan, which was recorded in
Other (income) expense. In 1996, the Company recognized $2.1 million of interest
income related to the above two loans, which represents the portion of Sumas'
earnings not recognized by the Company related to its equity investment in
Sumas.

In September 1997, the Company entered into a loan agreement with SEI's
sole shareholder wherein the Company agreed to make available a line of credit
up to $15.0 million, the proceeds of which are required to be used to develop a
new project. SEI has guaranteed the payment and performance of obligations under
this agreement and borrowings under the agreement will be collateralized by the
new project and the sole shareholder's 100% interest in SEI. The loan agreement
will expire on December 31, 2003.

TEXAS CITY AND CLEAR LAKE POWER PLANTS

In connection with the acquisition of TCC, the Company purchased from the
existing lenders the $155.6 million of outstanding project debt of the Texas
City Power Plant (approximately $53.0 million) and the Clear Lake Power Plant
(approximately $102.6 million). At December 31, 1997, there were loans
receivable of $37.1 million from Texas City and $94.7 million from Clear Lake
(of these amounts $30.5 million is current and $101.3 million is long term). The
effective interest rate on the loan to Texas City including the effect of the
swap arrangement, was approximately 7.9% at December 31, 1997; the loan matures
June 30, 1999. The effective interest rate on the loan to Clear Lake, including
the effect of the existing swap arrangement, was approximately 8.3%; the loan
matures December 31, 2003. Both notes are secured by the assets of the
respective partnerships.

CALPINE VAPOR INC.

In November 1995, Calpine Vapor Inc. ("Vapor") entered into agreements with
Constructora y Perforadora Latina, S.A. de C.V. ("Coperlasa") and certain
Mexican bank lenders to loan $18.5 million to Coperlasa in connection with a
geothermal steam production contract at the Cerro Prieto geothermal resource
("Cerro Prieto Project") in Baja California, Mexico (see Note 2, Concentration
of Credit Risks). The resource currently produces electricity from geothermal
power plants owned and operated by Comision Federal de Electricidad ("CFE"),
Mexico's national utility. The steam field contract is between Coperlasa and
CFE. Vapor receives fees for technical services provided to the project. At
December 31, 1997 and 1996, notes receivable were $16.1 million and $18.0
million, respectively. Interest accrues on the outstanding notes receivable at
approximately 18.9%. The Company is deferring the recognition of interest income
from this note

distribution to support the collectibility of accrued interest.

7. REVOLVING CREDIT FACILITY AND LINES OF CREDIT

At December 31, 1997 and 1996, the Company had a $50.0 million credit
facility available with a consortium of commercial lending institutions which
include The Bank of Nova Scotia, ING, Sumitomo Bank of California and Canadian
Imperial Bank of Commerce. As of December 31, 1997, the Company had no
borrowings and $9.4 million of letters of credit outstanding. This amount
reflects $6.0 million to secure performance with the Clear Lake Power Plant,
$1.5 million to secure performance under a purchase power agreement, and $1.9
million related to operating expenses at the Watsonville Power Plant. At
December 31, 1996, the Company had no borrowings and $5.9 million of letters of
credit outstanding, which reflected $3.0 million to secure performance with the
Pasadena Power Plant and $2.9 million related to operating expenses at the
Watsonville Power Plant. Borrowings bear interest at The Bank of Nova Scotia's
base rate or at the London InterBank Offering Rate ("LIBOR"), plus an applicable
margin. Interest is paid on the last day of each interest period for such loans,
but not less often than quarterly, based on the principal amount outstanding
during the period for base rate loans, and on the last day of each applicable
interest period, but not less often than 90 days, for LIBOR loans. The credit
agreement expires in September 1999. The credit agreement specified that the
Company maintain certain covenants with which the Company was in compliance.
Commitment fees related to this line of credit are charged based on 0.50% of
committed unused credit.

At December 31, 1997 and 1996, the Company had a loan facility with
available borrowings totaling $1.2 million. As of December 31, 1997, the Company

Senior-Term and Junior-Term Loans -- The Company entered into Senior-Term
and Junior-Term Loans in connection with the Company's acquisition of CGC in
1993. On July 8, 1997, the Company repaid all Senior-Term and Junior-Term Loans
before their maturity date from the proceeds of the 8 3/4% Senior Notes Due
2007. In connection with this transaction, the Company terminated one swap
transaction and retained one swap transaction, which was redesignated to other
floating rate financings. The Company had entered into swap transactions to
minimize the impact of changes in interest rates on a portion of the Senior-
Term loans. At December 31, 1997, the remaining swap had an effective interest
rate of 9.9%. The Company

is potentially exposed to credit risk in an event of non-performance by the
other parties to the swap agreements.

Notes Payable to Banks -- In June 1995, the Company entered into an
agreement with Sumitomo Bank to finance the acquisition of the Greenleaf Power
Plants. Of the $71.9 million debt outstanding at December 31, 1997, $56.8
million bears interest fixed at 7.4%, with the remaining floating rate portion
accruing interest at LIBOR, plus an applicable margin (6.5% at December 31,
1997). At December 31, 1996, $74.7 million of debt was outstanding, of which
$59.0 million was at the fixed interest rate of 7.4%, with the remaining
floating rate portion accruing interest at approximately 6.2%. This debt is
secured by all of the assets of the Greenleaf Power Plants. Interest on the
floating rate portion may be at Sumitomo's base rate plus an applicable margin
or at LIBOR plus an applicable margin. Interest on base rate loans is paid at
the end of each calendar quarter, and interest on LIBOR based loans is paid on
each maturity date, but not less often than quarterly, based on the principal
amount outstanding during the period. At the Company's discretion, the LIBOR
based loans may be held for various maturity periods of at least 1 month up to
12 months. The $71.9 million debt is being repaid quarterly, with a final
maturity date of December 31, 2010. The credit agreement specifies that the
Company maintain certain covenants in which the Company was in compliance at
December 31, 1997.

On August 29, 1996, the Company entered into an agreement with Banque
Nationale de Paris ("BNP") to finance the acquisition of the Gilroy Power Plant.
As of December 31, 1997, BNP had provided a $120.5 million loan consisting of a
15-year tranche in the amount of $86.9 million and an 18-year tranche in the
amount of $33.6 million. As of December 31, 1996, BNP had provided a $119.8
million loan consisting of a 15-year tranche in the amount of $84.8 million and
an 18-year tranche in the amount of $35.0 million. The debt is secured by all of
the assets of the Gilroy Power Plant. A portion of the BNP notes bears interest
fixed at a weighted average of 6.6% as of December 31, 1997 and 1996 (see
discussion below), with the remainder accruing interest at floating rate.
Interest on the floating rate portion may be at BNP's base rate plus an
applicable margin or at LIBOR plus an applicable margin (7.1% and 6.6% at
December 31, 1997 and 1996, respectively). Interest on the loans is payable not
less often than quarterly. Interest on LIBOR based loans is paid on each
maturity date, but not less often than quarterly. At the Company's discretion,
LIBOR based loans may be held for various maturity periods of at least 1 month
and up to 12 months. The $120.5 million debt is repaid semi-annually with a
final maturity date of August 28, 2011. Commitment fees are charged based on 1%
to 1.125% of committed unused credit. The Company entered into four interest
rate swap agreements to minimize the impact of changes in interest rates. These
agreements fix the interest on $85.1 million of principal at a weighted average
interest rate of 6.6%. The interest rate swap agreements mature through August
2011. The Company is exposed to credit risk in the event of non-performance by
the other parties to the swap agreements.

On June 23, 1997, the Company entered into a $125.0 million non-recourse
project financing with The Bank of Nova Scotia. Proceeds were utilized for the
acquisition of the 50% interest in TCC and the purchase from the lenders of
$155.6 million of outstanding non-recourse project financing. The $125.0 million
non-recourse project financing matures on June 22, 1998. The Company expects to
refinance this non-recourse project financing prior to maturity. On December 31,
1997, $103.4 million of borrowings were outstanding which bear interest at The
Bank of Nova Scotia's base rate or LIBOR, plus an applicable margin
(approximately 7.2% at December 31, 1997). The Company utilized swap
arrangements to minimize the impact of potential changes in interest rates on
the project debt. The effective interest rate, including the effect of the swap
arrangement, was approximately 7.1% at December 31, 1997. The interest rate swap
agreements mature in June 1998. The Company has potential exposure to credit
risk in the event of non-performance by other parties to the swap agreements.
The credit agreement specifies that the Company maintain certain covenants in
which the Company was in compliance at December 31, 1997.

The non-recourse project financing is held by subsidiaries of Calpine. The
debt agreements governing the non-recourse project financing generally restrict
their ability to pay dividends, make distributions or otherwise transfer funds.
The dividend restrictions in such agreements generally require that, prior to
the payment of dividends, distributions or other transfers, the subsidiary or
other affiliate must provide for the payment of other obligations, including
operating expenses, debt service and reserves.

9. NOTES PAYABLE

At December 31, 1996, the Company had a non-interest bearing promissory
note for $6.5 million payable to Natomas Energy Company, a wholly-owned
subsidiary of Maxus Energy Company. This note had been discounted to yield 8.0%
per annum, due September 9, 1997, and had a carrying value of $6.2 million at
December 31, 1996. On July 8, 1997, the Company repaid the promissory note
before its maturity date from the proceeds of the 8 3/4% Senior Notes Due 2007
(see Note 10).

10. SENIOR NOTES

On July 8, 1997, the Company issued $200.0 million aggregate principal
amount of 8 3/4% Senior Notes Due 2007. Transaction costs of $9.7 million
incurred in connection with the debt offering were capitalized and are included
in Other assets and amortized over the ten-year life of the 8 3/4% Senior Notes
Due 2007.

On September 10, 1997, the Company issued an additional $75.0 million
aggregate principal amount of 8 3/4% Senior Notes Due 2007.

In May and June 1997, the Company executed five interest rate hedging
transactions related to debt. The notional value of the debt was $182.0 million
and was designed to eliminate interest rate risk for the period from May 1997 to
July 1997 when the $200.0 million of 8 3/4% Senior Notes Due 2007 were priced.
These interest rate hedging transactions were designated as a hedge of the
anticipated bond offering, and the resulting $3.0 million cost resulting from
the hedges is being amortized over the life of the bonds. The effective

covenants with which the Company was in compliance. The Company may, under
certain circumstances, be limited in its ability to make restricted payments, as
defined, which include dividends and certain purchases and investments, incur
additional indebtedness and engage in certain transactions.

11. PROVISION FOR INCOME TAXES

The Company follows the liability method of accounting for income taxes
whereby deferred income taxes are recognized for the tax consequences of
"temporary differences" to the extent they are not reduced by net operating loss
and tax credit carryforwards by applying enacted statutory rates.

The components of the deferred tax liability as of December 31, 1997 and
1996 are (in thousands):



1997 1996

CALPINE CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
FOR THE YEARS ENDED DECEMBER 31, 1997, 1996 AND 1995

The net operating loss and credit carryforwards consist of federal net
operating loss carryforwards which expire 2005 through 2010 and federal and
state alternative minimum tax credit carryforwards which can be carried forward
indefinitely. At December 31, 1997, the federal net operating loss carryforwards
were approximately $11.3 million. At December 31, 1997, state net operating
losses have been fully utilized. At December 31, 1997, federal and state
alternative minimum tax credit carryforwards were approximately $10.6 million
and $3.6 million, respectively. In 1997 and 1996, the Company decreased its
deferred income tax liability by $2.1 million and $769,000 to reflect the change
in the California state income tax rate from 9.3% to 8.8% effective January 1,
1997 and to reflect the decrease in the California tax rate due to the Company's
expansion into states other than California.

Realization of the deferred tax assets and federal net operating loss
carryforwards is dependent, in part, on generating sufficient taxable income
prior to expiration of the loss carryforwards. In September 1996, the Company
underwent an ownership change as a result of the initial public offering of the
Company's common stock. This ownership change limits the amount of net operating
loss and credit carryforwards available to offset current tax liabilities.
Although realization is not assured, management believes it is more likely than
not that all of the deferred tax asset will be realized based on estimates of
future taxable income. The amount of the deferred tax asset considered
realizable, however, could be reduced in the near term if estimates of future
taxable income during the carryforward period are reduced.

The provision for income taxes for the years ended December 31, 1997, 1996
and 1995 consists of the following (in thousands):



1997 1996 1995

12. RETIREMENT SAVINGS PLAN

The Company has a defined contribution savings plan under Section 401(a)
and 501(a) of the Internal Revenue Code. The plan provides for tax deferred
salary deductions and after-tax employee contributions. Employees automatically
become participants on the first quarterly entry date after completion of three
months of service. Contributions include employee salary deferral contributions
and a 3% employer profit-sharing contribution. Employer profit-sharing
contributions in 1997, 1996, and 1995 totaled $588,000, $485,000 and $350,000,
respectively.

13. STOCKHOLDERS' EQUITY

Common Stock

In September 1996, the Company completed an initial public offering of
18,045,000 shares of its common stock with $0.001 par value per share (the
"Common Stock Offering"). In the Common Stock Offering, the Company issued and
sold 5,477,820 shares of common stock and Electrowatt Ltd. ("Electrowatt") sold
12,567,180 shares of common stock, representing its entire ownership interest in
the Company. As a result of the Common Stock Offering, Electrowatt no longer
owns any interest in the Company. The Company received approximately $82.1
million of net proceeds from the Common Stock Offering. In October 1996, the
Company issued an additional 1,793,400 shares of common stock to cover
over-allotments of shares in connection with the Common Stock Offering and
received approximately $27.1 million of net proceeds. In connection with the
Common Stock Offering, the Company completed a 5.194-for-1 stock split of the
Company's common stock and converted the Company's outstanding Series A
Preferred Stock into shares of common stock. The accompanying financial
statements reflect the stock split retroactively for all periods presented.

Preferred Stock and Preferred Share Purchase Rights

The Company had 5,000,000 authorized shares of Series A Preferred Stock,
all of which were issued on March 21, 1996 to Electrowatt. The shares of Series
A Preferred Stock were not publicly traded. No dividends were payable on the
Series A Preferred Stock. The Series A Preferred Stock contained provisions
regarding liquidation and conversion rights. Upon the consummation of the Common
Stock Offering, all of the Series A Preferred Stock were converted into
approximately 2.2 million shares of common stock and sold to the public in the
Common Stock Offering by Electrowatt.

On June 5, 1997, the Board of Directors adopted a Stockholders Rights Plan
("Rights Plan") to strengthen the Board of Directors ability to protect the
Company's stockholders. The Rights Plan is designed to protect against abusive
or coercive takeover tactics that are not in the best interests of the Company
and its stockholders. To implement the Rights Plan, the Board of Directors
declared a dividend of one preferred share purchase right (a "Right") for each
outstanding share of common stock, par value $0.001 per share, held on record as
of June 18, 1997. On December 31, 1997, there were 19,905,233 Rights
outstanding. Each Right initially represents a contingent right to purchase,
under certain circumstances, one one-thousandth of a share (a "Unit") of Series
A Junior Participating Preferred Stock, par value $0.001 per share (the
"Preferred Stock"), of the Company at a price of $80.00 per Unit, subject to
adjustment. The Rights become exercisable and trade independently from the
Company's common stock upon the public announcement of the acquisition by a
person or group of 15% or more of the Company's common stock, or ten days after
commencement of a tender or exchange offer that would result in the acquisition
of 15% or more of the Company's common stock. Each Unit of Preferred Stock
purchased upon exercise of the Rights will be entitled to a dividend equal to
any dividend declared per share of common stock and will have one vote, voting
together with the common stock. In the event of liquidation, each share of
Preferred Stock will be entitled to any payment made per share of common stock.

If the Company is acquired in a merger or other business combination
transaction after a person or group has acquired 15% or more of the Company's
common stock, each Right will entitle its holder to purchase at the Right's
exercise price a number of the acquiring company's common shares having a market
value of twice such exercise price. In addition, if a person or group acquires
15% or more of the Company's common stock, each Right will entitle its holder
(other than the acquiring person or group) to purchase, at the Right's exercise
price, a number of fractional shares of the Company's Preferred Stock or shares
of common stock having a market value of twice such exercise price.

The Rights expire June 18, 2007 unless redeemed earlier by the Company's
Board of Directors. The Board of Directors can redeem the Rights at a price of
$0.01 per Right at any time before the Rights become exercisable, and thereafter
only in limited circumstances.

14. STOCK-BASED COMPENSATION PROGRAMS

1996 Employee Stock Purchase Plan

The Company adopted the 1996 Employee Stock Purchase Plan ("ESPP") in July
1996. Eligible employees may purchase up to 275,000 shares of common stock at
semi-annual intervals through periodic payroll deductions. Purchases are limited
to 15 percent of an employee's eligible compensation, up to a maximum of $25,000
per year. Shares are purchased on January 31 and July 31 of each year. Under the
ESPP, 54,149 shares were issued at a weighted average fair value of $13.65 per
share in 1997. On January 30, 1998, employees participating in the ESPP
purchased an additional 30,385 shares at a weighted average fair value of $13.39
per share. The purchase price is 85% of the lower of (i) the fair market value
of the common stock on the participant's entry date into the offering period, or
(ii) the fair market value on the semi-annual purchase date.

1996 Stock Incentive Plan

The Company adopted the 1996 Stock Incentive Plan ("SIP") in September
1996. The SIP succeeded the Company's previously adopted stock option program.
The Company accounts for the SIP under Accounting Principles Board Opinion No.
25, "Accounting for Stock Issued to Employees" under which no compensation cost
has been recognized. Had compensation cost for the SIP been determined
consistent with the methodology of SFAS No. 123, "Accounting for Stock-Based
Compensation", the Company's net income and earnings per share would have been
reduced to the following pro forma amounts (in thousands, except per share
amounts):



1997 1996 1995
------- ------- -------

Net income As reported $34,699 $18,692 $ 7,378
Pro Forma $33,528 $18,145 $ 7,232
Basic earnings per share As reported $ 1.74 $ 1.45 $ 0.71
Pro Forma $ 1.68 $ 1.41 $ 0.70
Diluted earnings per share As reported $ 1.65 $ 1.26 $ 0.67
Pro Forma $ 1.60 $ 1.22 $ 0.66


The fair value of options granted in 1995, 1996 and 1997 was $1.23, $3.29
and $10.28 on the date of grant using the Black-Scholes option pricing model
with the following weighted-average assumptions: expected dividend yields of 0%,
expected volatility of 44%, 27% and 0% for 1997, 1996 and 1995, risk-free
interest rates of 5.8%, 6.2% and 5.4% for 1997, 1996 and 1995, respectively, and
expected lives of 3 years for 1995 and 1996, and 7 years for 1997.

Because the SFAS No. 123 methodology of accounting has not been applied to
options granted prior to January 1, 1995, the resulting pro forma compensation
cost may not be representative of that to be expected in

future years. The Company may grant options for up to 4,041,858 shares under the
SIP. As of December 31, 1997, the Company had granted options to purchase
2,519,803 shares of common stock. Under the SIP, the option exercise price
equals the stock's fair market value on date of grant. The SIP options generally
vest after four years and expire after 10 years. Changes in options outstanding,
granted, exercisable and cancelled by the Company during the years 1997, 1996,
and 1995, whether under the option or purchase plan were as follows:

16. COMMITMENTS AND CONTINGENCIES

Capital Projects -- The Company has 1998 commitments of $19.8 million
related to the construction of the Pasadena Power Plant (see Note 3, "Pasadena
Cogeneration Project").

Royalties and Leases -- The Company is committed under several geothermal
leases and right-of-way, easement and surface agreements. The geothermal leases
generally provide for royalties based on production revenue with reductions for
property taxes paid. The right-of-way, easement and surface agreements are based
on flat rates and are not material. Under the terms of certain geothermal
leases, royalties accrue at rates ranging from 7% to 12.5% of steam and effluent
revenue. Certain properties also have net profits and overriding royalty
interests ranging from approximately 1.45% to 28%, which are in addition to the
land royalties. Most lease agreements contain clauses providing for minimum
lease payments to lessors if production temporarily ceases or if production
falls below a specified level.

Expenses under these agreements for the years ended December 31, 1997, 1996
and 1995 are (in thousands):



1997 1996 1995
------- ------- -------

Production Royalties.................. $10,803 $10,793 $10,574
Lease payments........................ 222 246 225


Natural Gas Purchases -- The Company enters into short-term gas purchase
contracts with third parties to supply gas to its gas-fired cogeneration
projects.

Watsonville Operating Lease -- In June 1995, the Company acquired a 14.5
year operating lease (through December 2009) for the 28.5 megawatt natural
gas-fired cogeneration power plant located in Watsonville, California. Under the
terms of the lease, basic and contingent rents are payable each month during the
period from July through December. As of December 31, 1997, future basic rent
payments have remained the same from prior years at $2.9 million for 1996 and
1997, respectively. Future payment from 1998 to 2001 will continue at the
current rate of $2.9 million, and $24.4 million thereafter through December
2009. Contingent rent expense for 1997 and 1996 was $864,000 and $671,000,
respectively. This expense is based on the net of revenues less all operating
expenses, fees, reserve requirements, basic rent and supplemental rent payments.
Of the remaining balance, 60% is payable to the lessor and 40% is payable to the
Company.

Office and Equipment Leases -- The Company leases its corporate office,
Santa Rosa office facilities and certain office equipment under noncancellable
operating leases expiring through 2002. Future minimum lease payments under
these leases are (in thousands):



1998................................ $1,409

Lease payments are subject to adjustments for the Company's pro rata
portion of annual increases or decreases in building operating costs. In 1997,
1996, and 1995 rent expenses for noncancellable operating leases amounted to
$1.2 million, $1.0 million and $733,000, respectively.

Regulation and CPUC Restructuring -- Electricity and steam sales agreements
with PG&E are regulated by the California Public Utilities Commission ("CPUC").
In December 1995, the CPUC issued a decision which proposed the transition of
the regulated electric generation market to a competitive generation market
beginning January 1, 1998. Since the proposed restructure represented a
widespread impact on the market structure, requiring participation and oversight
of the Federal Energy Regulatory Commission (the "FERC"), the CPUC sought and
built a California consensus coalition which resulted in filings at the FERC
which permitted the CPUC and the FERC to collectively proceed with
implementation of the new competitive market structure. In late 1996,
comprehensive legislation, AB 1890 ("the Bill"), was signed into California law
which adopted the basic tenets of the CPUC electric industry restructure
decision and directed the CPUC to proceed with implementation of restructure
with customer choice of electricity supplier available no later than January 1,
1998. The Bill provided for market power mitigation by utility divestiture of
fossil generation plants, provided a four year transition period for utility
recovery of stranded costs, provided for sanctity of existing qualifying
facility ("QF") contracts with provision for voluntary restructure, established
an electricity rate freeze for the four year transition period for certain
customers, mandated a 10% rate reduction beginning January 1, 1998 and
continuing through the transition period for small commercial and residential
customers financed by issuance of rate reduction bonds, and provided specified
funds for continued public service programs including public interest research
and development and enhancement of in-state renewable energy resources, which
includes geothermal operations. In late 1997, the CPUC and the FERC issued
decisions which provided for January 1, 1998 implementation of the California
Independent Systems Operator ("ISO") responsible for centralized control and
reliable operation of the state-wide electric transmission grid and the Power
Exchange ("PX") responsible for the competitive electric energy auction. In late
1997, CPUC-approved sales of certain utility-owned fossil generation plants were
completed and applications were pending at the CPUC for sales of the remaining
utility-owned California fossil and geothermal power plants. Investor-owned
utilities, though transferring control to the ISO, will continue to own and
collect revenue from their transmission facilities and will continue to be
regulated utility distribution companies ("UDC") for all electric service
providers with default electric supplier responsibility.

In December 1997, mechanics for operation of the ISO and PX were not yet
fully perfected and implementation of deregulation was delayed to April 1, 1998.
The California Energy Commission ("CEC") was directed by the Bill to develop a
competitive mechanism for allocation and distribution of funds made available
for public interest research and development and enhancement of in-state
renewable resources. The CEC, in late 1997, issued its draft guidelines for
selective allocation and distribution of the funds which are to be available
over the four year transition period to a fully competitive electric services
industry. Though the

Company believes that implementation of electric industry restructure can
provide significant opportunity for independent power producers, the ultimate
impact of both increased competition and the changing regulatory environment on
the Company's future results from operations is uncertain.

A domestic electricity generating project must be a QF under the FERC
regulations in order to take advantage of certain rate and regulatory incentives
provided by the Public Utility Regulatory Policies Act of 1978, as amended
("PURPA"). PURPA exempts owners of QFs from the Public Utility Holding Company
Act of 1935, as amended ("PUHCA"), and exempts QFs from most provisions of the
Federal Power Act (the "FPA") and state laws concerning rate or financial
regulation. PURPA also requires that electric utilities purchase electricity
generated by QFs at a price based on the utility's "avoided cost", and that the
utility sell back-up power to the QF on a non-discriminatory basis. If one of
the projects in which the Company has an interest should lose its status as a
QF, the project would no longer be entitled to the exemptions from PUHCA and the
FPA. This could trigger certain rights of termination under the power sales
agreement, could subject the project to rate regulation as a public utility
under the FPA and state laws and could result in the Company inadvertently
becoming a public utility holding company. The Company believes that each of the
electricity generating projects in which the Company owns an interest currently
meets the requirements under PURPA necessary for QF status.

Litigation

On September 30, 1997, a lawsuit was filed by Indeck North American Power
Fund ("Indeck") in the Circuit Court of Cook County, Illinois against Norweb
plc. and certain other parties, including the Company. Some of Indeck's claims
relate to Calpine Gordonsville, Inc.'s acquisition of a 50% interest in
Gordonsville Energy L.P. from Northern Hydro Limited and Calpine Auburndale,
Inc.'s acquisition of a 50% interest in Auburndale Power Plant Partners Limited
Partnership from Norweb Power Services (No. 1) Limited. Indeck is claiming that
Calpine Gordonsville, Inc., Calpine Auburndale, Inc. and the Company tortiously
interfered with Indeck's contractual rights to purchase such interests and
conspired with other parties to do so. Indeck is seeking $25.0 million in
compensatory damages, $25.0 million in punitive damages, and the recovery of
attorneys' fees and costs. All the defendants filed motions to dismiss such
claims, which are currently pending. The Company believes that the claims of
Indeck are without merit and that the resolution of this matter will not have a
material adverse effect on the Company's financial position or results of
operations.

On February 17, 1998, the Company filed an action in the Superior Court of
California, Sonoma County, seeking injunctive and declaratory relief to prevent
PG&E from unilaterally assigning the Company's steam sales contract to the
prospective winning bidder in PG&E's recently announced auction of its power
plants in The Geysers. On January 14, 1998, PG&E filed an application with the
CPUC pursuant to Public Utilities Code Section 851 ("851 Filing"), in which it
seeks authorization to sell five electric generating plants and related assets.
Included in this proposed sale are The Geysers Geothermal Power Plants
(including Units 13 and 16) and certain of PG&E's fossil fueled steam-electric
generating plants. In PG&E's 851 Filing, PG&E announced its intention to assign
its rights and to delegate its duties under the Company's steam contract to the
successful third party purchaser of the Unit 13 and Unit 16 Power Plants. The
Company has been informed by PG&E that it will attempt to make such assignment
and delegation without first seeking and obtaining the approval and consent of
the Company. The Company is challenging the continued validity of the price term
of the steam sales contract following the proposed divestiture by PG&E of 98% of
its fossil fueled steam-electric generating plants, as the price term of the
steam sales contract is based on a complex formula that reflects PG&E's weighted
average cost of fossil and nuclear fuel from the preceding year.

In a related action, the Company has filed a protest with the CPUC which
raises issues similar to those addressed in the above-referenced lawsuit and, in
addition, challenges certain inaccuracies contained in

F-39

FOR THE YEARS ENDED DECEMBER 31, 1997, 1996 AND 1995

portions of PG&E's 851 Filings related to Unit 13 and Unit 16. As no discovery
has been conducted in either matter, nor has any answer been filed in the
lawsuit, the Company is unable to predict the outcome of these cases.

An action was filed against Lockport Energy Associates, L.P. ("LEA") on
August 7, 1997 by New York State Electricity and Gas Company ("NYSEG") in the
Federal District Court for the Northern District of New York. NYSEG has
requested the Court to direct the FERC and the New York Public Service
Commission ("NYPSC"), to modify contract rates to be paid to the Lockport Power
Plant. On October 14, 1997, NYPSC, a named defendant in the NYSEG action, filed
a cross-claim alleging that the FERC violated PURPA and the Federal Power Act by
failing to reform the NYSEG contract which was previously approved by the NYPSC.
LEA continues to vigorously defend this action, although it is unable to predict
the outcome of this case. The Company retains the right to require BUG to
purchase the Company's interest in the Lockport Power Plant for $18.9 million,
less equity distributions received by the Company, at any time before December
19, 2001. In the event the NYSEG's action is successful, the Company may choose
to exercise its right to require BUG to purchase its interest in the Lockport
Power Plant.

There is currently a dispute between Texas-New Mexico Power Company ("TNP")
and Clear Lake Cogeneration Limited Partnership ("CLC"), which owns the Clear
Lake Power Plant, regarding certain costs and other amounts that TNP has
withheld from payments due under the power sales agreement. As of December 31,
1997, TNP has withheld approximately $5.4 million related to transmission
charges and has continued to withhold approximately $450,000 per month
thereafter. CLC filed a petition for declaratory order with the Texas Public
Utilities Commission ("Texas PUC") on October 2, 1997 requesting that the Texas
PUC declare that TNP's withholding is in error. This matter is pending before
the Texas PUC. In addition, as of December 31, 1997, TNP has withheld
approximately $4.4 million of standby power charges and has continued to
withhold approximately $270,000 per month thereafter. CLC has filed a lawsuit in
Texas against TNP claiming that TNP is in breach of certain provisions of the
power sales agreement, including the provisions involved in the disputes
described above, and is seeking in excess of $15.0 million in damages. A trial
is scheduled to begin on June 1, 1998. The Company is unable to predict the
outcome of either of these proceedings.

The Company is involved in various other claims and legal actions arising
out of the normal course of business. The Company does not expect that the
outcome of these proceedings will have a material adverse effect on the
Company's financial position or results of operations, although no assurance can
be given in this regard.

======= ======= =======


Basic earnings per share for the year ended December 31, 1996 was computed
using the weighted average number of common shares outstanding. Diluted earnings
per share was computed using the weighted average number of common and common
equivalent shares for outstanding stock options. Options to purchase
approximately 385,000 shares of common stock at a weighted average price of
$18.00 per share were outstanding during the fourth quarter of 1997. These
options were not included in the computation of diluted earnings per share
because the options' exercise price was greater than the average market price of
common shares. The change in the way the Company previously reported earnings
per share for financial reporting purposes is in part due to the adoption of
SFAS No. 128 and subsequently, SAB No. 98 on "Computations of Earnings per
Share" which became effective in February 1998.

18. QUARTERLY CONSOLIDATED FINANCIAL DATA (UNAUDITED)

The Company's quarterly operating results have fluctuated in the past and
may continue to do so in the future as a result of a number of factors,
including, but not limited to, the timing and size of acquisitions, the
completion of development projects, the timing and amount of curtailment, and
variations in levels of production. Furthermore, the majority of capacity
payments under certain of the Company's power sales agreements are received
during the months of May through October.

CALPINE CORPORATION

NOTES TO CONDENSED FINANCIAL STATEMENTS
DECEMBER 31, 1997, 1996 AND 1995

1. ORGANIZATION AND OPERATION OF CALPINE

Calpine Corporation ("Calpine"), a Delaware Corporation, is engaged in the
development, acquisition, ownership and operation of power generation facilities
in the United States. Calpine has ownership interests in and operates geothermal
steam fields, geothermal power generation facilities, and natural gas-fired
cogeneration facilities through subsidiaries and investees.

In July 1996, Calpine's Board of Directors authorized the reincorporation
of Calpine in Delaware in connection with Calpine's initial public offering. In
addition, the Board of Directors approved a stock split of approximately
5.194-for-1. In September 1996, the reincorporation of Calpine and the stock
split became effective. The accompanying financial statements reflect the
reincorporation and the stock split as if such transactions had been effective
for all periods.

For the purposes of these registrant-only financial statements, Calpine's
wholly-owned subsidiaries are accounted for under the equity method and are
included in investments in power projects in the accompanying balance sheets.

These financial statements should be read in conjunction with Calpine
Corporation and Subsidiaries Consolidated Financial Statements.

2. SENIOR NOTES

On July 8, 1997, the Company issued $200.0 million aggregate principal
amount of 8 3/4% Senior Notes Due 2007. Transaction costs of $9.7 million
incurred in connection with the debt offering were capitalized and are included
in Other assets and are amortized over the ten-year life of the 8 3/4% Senior
Notes Due 2007.

On September 10, 1997, the Company issued an additional $75.0 million
aggregate principal amount of 8 3/4% Senior Notes Due 2007. The net proceeds
were for general corporate purposes.

In May and June 1997, the Company executed five interest rate hedging
transactions related to debt. The notional value of the debt was $182.0 million
and was designed to eliminate interest rate risk for the period from May 1997 to
July 1997 when the $200.0 million of 8 3/4% Senior Notes Due 2007 were priced.
These interest rate hedging transactions were designated as a hedge of the
anticipated bond offering, and the resulting $3.0 million cost resulting from
the hedges is being amortized over the life of the bonds. The effective interest
rate on the $275.0 million aggregate principal amount after the hedging
transactions and the amortization of transaction costs was 9.1%.

The 8 3/4% Senior Notes Due 2007 will mature on July 15, 2007. The Company
has no sinking fund or mandatory redemption obligations with respect to the
8 3/4% Senior Notes Due 2007. Interest is payable semi-annually on January 15
and July 15 of each year while the 8 3/4% Senior Notes Due 2007 are outstanding,
commencing on January 15, 1998. Based on the traded yield to maturity, the
approximate fair market value of the 8 3/4% Senior Notes Due 2007 was $280.5
million as of December 31, 1997.

On May 16, 1996, the Company issued $180.0 million aggregate principal
amount of 10 1/2% Senior Notes Due 2006. Transaction costs of $5.1 million
incurred in connection with the public debt offering were recorded as other
assets and are amortized over the ten-year life of the 10 1/2% Senior Notes Due
2006. The effective interest rate of the $180.0 million aggregate principal
amount after the amortization of transaction costs was 10.7%.

The 10 1/2% Senior Notes Due 2006 will mature on May 15, 2006. The Company
has no sinking fund or mandatory redemption obligations with respect to the
10 1/2% Senior Notes Due 2006. Interest is payable semi-annually on May 15 and
November 15. Based on the traded yield to maturity, the approximate fair market
value of the 10 1/2% Senior Notes Due 2006 was $196.2 million as of December 31,
1997.

CALPINE CORPORATION

NOTES TO CONDENSED FINANCIAL STATEMENTS (CONTINUED)
DECEMBER 31, 1997, 1996 AND 1995

The 9 1/4% Senior Notes Due 2004 will mature on February 1, 2004. The
Company has no sinking fund or mandatory redemption obligations with respect to
the 9 1/4% Senior Notes Due 2004. Interest is payable semi-annually on February
1 and August 1. Based on the traded yield to maturity, the approximate fair
market value of the 9 1/4% Senior Notes Due 2004 was $108.7 million as of
December 31, 1997. The effective interest rate on the $105.0 million aggregate
principal amount after amortization of transaction costs was 9.6%.

The Senior Note indentures specify that the Company maintains certain
covenants with which the Company was in compliance. The Company may, under
certain circumstances, be limited in its ability to make restricted payments, as
defined, which include dividends and certain purchases and investments, incur
additional indebtedness and engage in certain transactions.

3. NOTES RECEIVABLE

In May 1993, in accordance with the Sumas Cogeneration, L.P. ("Sumas")
partnership agreement, the Company was entitled to receive a distribution of
$1.5 million and Sumas Energy, Inc. ("SEI"), the Company's partner in Sumas, was
required to make a capital contribution of $1.5 million. In order to meet SEI's
$1.5 million capital contribution requirement, the Company loaned $1.5 million
to the sole shareholder of SEI, who in turn loaned the funds to SEI, who in turn
contributed the capital to Sumas. The interest rate on the loan was 20% and was
secured by a security interest in the loan between SEI and its sole shareholder.
The Company received all principal plus accrued interest totaling $2.8 million
in 1997.

In March 1994, the Company loaned $10.0 million to the sole shareholder of
SEI. The interest rate on the loan was 16.25%. The loan was secured by a pledge
to Calpine of SEI's interest in Sumas. The Company deferred the recognition of
interest income from these notes until Sumas generated net income.

In September 1997, the Company entered into a loan agreement with SEI's
sole shareholder wherein the Company agreed to make available a line of credit
up to $15.0 million, the proceeds of which are required to be used to develop a
new project. SEI has guaranteed the payment and performance of obligations under
this agreement and borrowings under the agreement will be collateralized by the
new project and the sole shareholder's 100% interest in SEI. The loan agreement
will expire on December 31, 2003.

During 1997, the $10.0 million loan was sold to a third party. The Company
received all unpaid principal and interest related to both loans and recognized
a total of $6.9 million of the interest income during 1997 (of which $3.5
million was previously deferred). In addition, the Company recorded a $1.1
million gain upon the sale of the $10.0 million loan, which was recorded in
Other (income) expense. In 1996, the Company recognized $2.1 million of interest
income related to the above two loans, which represents the portion of Sumas'
earnings not recognized by the Company related to its equity investment in
Sumas.

4. REVOLVING CREDIT FACILITY AND LINE OF CREDIT

At December 31, 1997 and 1996, Calpine had a $50.0 million credit facility
available with a consortium of commercial lending institutions which include The
Bank of Nova Scotia, ING U.S. Capital Corporation, Sumitomo Bank of California
and Canadian Imperial Bank of Commerce. As of December 31, 1997, the Company had
no borrowings and $9.4 million of letters of credit outstanding. This amount
reflects $6.0 million to secure performance with the Clear Lake Power Plant,
$1.5 million to secure performance under a purchase power agreement, and $1.9
million related to operating expenses at Calpine Monterey Cogeneration Inc.,
("CMCI"). At December 31, 1996, Calpine had no borrowings and $5.9 million of
letters of credit outstanding, which reflected $3.0 million to secure
performance with the Pasadena Power Plant and $2.9 million related to operating
expenses at CMCI. Borrowings bear interest at The Bank of Nova Scotia's base
rate plus an applicable margin or at the London Interbank Offered Rate ("LIBOR")
plus an applicable margin. Interest is paid on the last day of each interest
period for such loans, but not less often than quarterly,

F-48
102
CALPINE CORPORATION

NOTES TO CONDENSED FINANCIAL STATEMENTS (CONTINUED)
DECEMBER 31, 1997, 1996 AND 1995

based on the principal amount outstanding during the period for base rate loans,
and on the last day of each applicable interest period, but not less often than
90 days, for LIBOR loans. The credit agreement expires in September 1999. The
credit agreement specified that Calpine maintain certain covenants with which
Calpine was in compliance. Commitment fees related to this line of credit are
charged based on 0.50% of committed unused credit.

At December 31, 1997 and 1996, Calpine had a loan facility with available
borrowings totaling $1.2 million. As of December 31, 1997, Calpine had no
borrowings and $74,000 of letters of credit outstanding. There were no
borrowings and $900,000 of letters of credit outstanding as of December 31,
1996.

5. COMMITMENTS AND CONTINGENCIES

Office and Equipment Leases -- The Company leases its corporate office,
Santa Rosa office facilities and certain office equipment under noncancellable
operating leases expiring through 2002. Future minimum lease payments under
these leases are (in thousands).

Lease payments are subject to adjustments for the Company's pro rata
portion of annual increases or decreases in building operating costs. In 1997,
1996, and 1995, rent expenses for noncancellable operating leases amounted to
$1.2 million, $1.0 million and $733,000, respectively.

Regulation and CPUC Restructuring -- Electricity and steam sales agreements
with Pacific Gas and Electric Company ("PG&E") are regulated by the California
Public Utilities Commission ("CPUC"). In December 1995, the CPUC issued a
decision which proposed the transition of the regulated electric generation
market to a competitive generation market beginning January 1, 1998. Since the
proposed restructure represented a widespread impact on the market structure
requiring participation and oversight of the Federal Energy Regulatory
Commission ("the FERC"), the CPUC sought and built a California consensus
coalition which resulted in filings at the FERC which permitted the CPUC and the
FERC to collectively proceed with implementation of the new competitive market
structure. In late 1996, comprehensive legislation, (AB 1890 (the "Bill")), was
signed into California law which adopted the basic tenets of the CPUC electric
industry restructure decision and directed the CPUC to proceed with
implementation of restructure with customer choice of electricity supplier
available no later than January 1, 1998. The Bill provided for market power
mitigation by utility divestiture of fossil generation plants, provided a four
year transition period for utility recovery of stranded costs, provided for
sanctity of existing contracts with provision for voluntary restructure,
established an electricity rate freeze for the four year transition period,
mandated a 10% rate reduction beginning January 1, 1998 and continuing through
the transition period for small commercial and residential customers financed by
issuance of rate reduction bonds, and provided specified funds for continued
public service programs including public interest research and development and
enhancement of in-state renewable energy resources, which includes geothermal
operations. In late 1997 the CPUC and FERC issued decisions which provided for
the January 1, 1998 implementation of the California Independent Systems
Operator ("ISO"), responsible for centralized control and reliable operation of
the state-wide electric transmission grid, and the Power Exchange ("PX"),
responsible for the competitive electric energy auction. In late 1997,
CPUC-approved sales of certain utility-owned fossil generation plants were
completed and applications were pending at the CPUC for sales of the remaining
utility-owned

F-49

CALPINE CORPORATION

NOTES TO CONDENSED FINANCIAL STATEMENTS (CONTINUED)
DECEMBER 31, 1997, 1996 AND 1995

California fossil and geothermal power plants. Investor-owned utilities, though
transferring control to the ISO, will continue to own and collect revenue from
their transmission facilities and will continue to be regulated utility
distribution companies ("UDC") for all electric service providers with default
electric supplier responsibility.

In December 1997, mechanics for operation of the ISO and PX were not yet
fully perfected and implementation of deregulation was delayed to April 1, 1998.
The California Energy Commission ("CEC") was directed by the Bill to develop a
competitive mechanism for allocation and distribution of funds made available
for public interest research and development and enhancement of in-state
renewable resources. The CEC in late 1997 issued its draft guidelines for
selective allocation and distribution of the funds which are to be available
over the four year transition period to a fully competitive electric services
industry. Though Calpine believes that implementation of electric industry
restructure can provide significant opportunity for independent power producers,
the ultimate impact of both increased competition and the changing regulatory
environment on Calpine's future results from operations is uncertain.

A domestic electricity generating project must be a qualifying facility
("QF") under FERC regulations in order to take advantage of certain rate and
regulatory incentives provided by the Public Utility Regulatory Policies Act of
1978, as amended ("PURPA"). PURPA exempts owners of QFs from the Public Utility
Holding Company Act of 1935, as amended ("PUHCA"), and exempts QFs from most
provisions of the Federal Power Act ("FPA") and state laws concerning rate or
financial regulation. PURPA also requires that electric utilities purchase
electricity generated by QFs at a price based on the utility's "avoided cost",
and that the utility sell back-up power to the QF on a non-discriminatory basis.
If one of the projects in which Calpine has an interest should lose its status
as a QF, the project would no longer be entitled to the exemptions from PUHCA
and the FPA. This could trigger certain rights of termination under the power
sales agreement, could subject the project to rate regulation as a public
utility under the FPA and state laws and could result in Calpine inadvertently
becoming a public utility holding company. Calpine believes that each of the
electricity generating projects in which Calpine owns an interest currently
meets the requirements under PURPA necessary for QF status.

LITIGATION --

On September 30, 1997, a lawsuit was filed by Indeck North American Power
Fund ("Indeck") in the Circuit Court of Cook County, Illinois against Norweb
plc. and certain other parties, including the Company. Some of Indeck's claims
relate to Calpine Gordonsville, Inc.'s acquisition of a 50% interest in
Gordonsville Energy L.P. from Northern Hydro Limited and Calpine Auburndale,
Inc.'s acquisition of a 50% interest in Auburndale Power Plant Partners Limited
Partnership from Norweb Power Services (No. 1) Limited. Indeck is claiming that
Calpine Gordonsville, Inc., Calpine Auburndale, Inc. and the Company tortiously
interfered with Indeck's contractual rights to purchase such interests and
conspired with other parties to do so. Indeck is seeking $25.0 million in
compensatory damages, $25.0 million in punitive damages, and the recovery of
attorneys' fees and costs. All the defendants has filed motions to dismiss such
claims, which are currently pending. Calpine believes that the claims of Indeck
are without merit and that the resolution of this matter will not have a
material adverse effect on its financial position or results of operations.

On February 17, 1998, Calpine filed an action in the Superior Court of
California, Sonoma County, seeking injunctive and declaratory relief to prevent
PG&E from unilaterally assigning Calpine's steam sales contract to the
prospective winning bidder in PG&E's recently announced auction of its power
plants in The Geysers. On January 14, 1998, PG&E filed an application with the
CPUC pursuant to Public Utilities Code Section 851 ("851 Filing"), in which it
seeks authorization to sell five electric generating plants and related assets.
Included in this proposed sale are The Geysers Geothermal Power Plants
(including Units 13 and 16) and certain of PG&E's fossil fueled steam-electric
generating plants. In PG&E's 851 Filing, PG&E

F-50
104
CALPINE CORPORATION

NOTES TO CONDENSED FINANCIAL STATEMENTS (CONTINUED)
DECEMBER 31, 1997, 1996 AND 1995

announced its intention to assign its rights and to delegate its duties under
Calpine's steam contract to the successful third party purchaser of the Unit 13
and Unit 16 Power Plants. Calpine has been informed by PG&E that it will attempt
to make such assignment and delegation without first seeking and obtaining the
approval and consent of Calpine. Calpine is challenging the continued validity
of the price term of the steam sales contract following the proposed divestiture
by PG&E of 98% of its fossil fueled steam-electric generating plants, as the
price term of the steam sales contract is based on a complex formula that
reflects PG&E's weighted average cost of fossil and nuclear fuel from the
preceding year.

In a related action, Calpine and CGC have filed a protest with the CPUC
which raises issues similar to those addressed in the above-referenced lawsuit
and, in addition, challenges certain inaccuracies contained in portions of
PG&E's 851 Filings related to Unit 13 and Unit 16. As no discovery has been
conducted in either matter, nor has any answer been filed in the lawsuit,
Calpine is unable to predict the outcome of these cases.

An action was filed against Lockport Energy Associates, L.P. ("LEA") on
August 7, 1997 by New York State Electricity and Gas Company ("NYSEG") in the
Federal District Court for the Northern District of New York. NYSEG has
requested the Court to direct the Federal Energy Regulatory Commission (the
"FERC") and the New York Public Service Commission ("NYPSC"), to modify contract
rates to be paid to the Lockport Power Plant. On October 14, 1997, NYPSC, a
named defendant in the NYSEG action, filed a cross-claim alleging that the FERC
violated PURPA and the Federal Power Act by failing to reform the NYSEG contract
which was previously approved by the NYPSC. LEA continues to vigorously defend
this action, although it is unable to predict the outcome of this case. Calpine
retains the right to require The Brooklyn Union Gas Company ("BUG") to purchase
Calpine's interest in the Lockport Power Plant for $18.9 million, less equity
distributions received by Calpine, at any time before December 19, 2001. In the
event the NYSEG's action is successful, Calpine may choose to exercise its right
to require BUG to purchase its interest in the Lockport Power Plant.

There is currently a dispute between Texas-New Mexico Power Company ("TNP")
and Clear Lake Cogeneration Limited Partnership ("CLC"), which owns the Clear
Lake Power Plant, regarding certain costs and other amounts that TNP has
withheld from payments due under the power sales agreement. As of December 31,
1997, TNP has withheld approximately $5.4 million related to transmission
charges and has continued to withhold approximately $450,000 per month
thereafter. CLC filed a petition for declaratory order with the Texas Public
Utilities Commission ("Texas PUC") on October 2, 1997 requesting that the Texas
PUC declare that TNP's withholding is in error. This matter is pending before
the Texas PUC. In addition, as of December 31, 1997, TNP has withheld
approximately $4.4 million of standby power charges and has continued to
withhold approximately $270,000 per month thereafter. CLC has filed a lawsuit in
Texas against TNP claiming that TNP is in breach of certain provisions of the
power sales agreement, including the provisions involved in the disputes
described above, and is seeking in excess of $15.0 million in damages. A trial
is scheduled to begin on June 1, 1998. Calpine is unable to predict the outcome
of either of these proceedings.

Calpine and its affiliates are involved in various other claims and legal
actions arising out of the normal course of business. Calpine does not expect
that the outcome of these proceedings will have a material adverse effect on
their financial position or results of operations, although no assurance can be
given in this regard.

INDEPENDENT AUDITOR'S REPORT

To the Partners
Sumas Cogeneration Company, L.P. and Subsidiary

We have audited the accompanying consolidated balance sheet of Sumas
Cogeneration Company, L.P. and Subsidiary as of December 31, 1997 and 1996, and
the related consolidated statements of income, changes in partners' deficit, and
cash flows for each of the three years ended December 31, 1997. These
consolidated financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these consolidated
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 audits to obtain
reasonable assurance about whether the consolidated financial statements are
free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the consolidated financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
consolidated financial statement presentation. We believe that our audits
provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Sumas
Cogeneration Company, L.P. and Subsidiary as of December 31, 1997 and 1996, and
the results of their operations and cash flows for each of the three years ended
December 31, 1997, in conformity with generally accepted accounting principles.

SUMAS COGENERATION COMPANY, L.P. AND SUBSIDIARY

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
DECEMBER 31, 1997

1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

General -- Sumas Cogeneration Company, L.P. (the Partnership) is a Delaware
limited partnership formed in 1991 between Sumas Energy, Inc. ("SEI"), the
general partner which currently holds a 50% interest in the profits and losses
of the Partnership, and Whatcom Cogeneration Partners, L.P. ("Whatcom"), the
sole limited partner which holds the remaining 50% Partnership interest. In
addition, Whatcom is entitled certain additional distribution amounts through
June 30, 2001, representing 20% of forecasted cash flows. Whatcom is owned
through affiliated companies by Calpine Corporation ("Calpine"). The Partnership
has a wholly-owned Canadian subsidiary, ENCO Gas, Ltd. ("Enco"), which is
incorporated in New Brunswick, Canada. The consolidated financial statements
include the accounts of the Partnership and ENCO (collectively, the Company).
All intercompany profits, transactions and balances have been eliminated in
consolidation.

The Partnership owns and operates an electrical generation facility (the
"Generation Facility") in Sumas, Washington. The Generation Facility is a
natural gas-fired combined cycle electrical generation plant which has a
nameplate capacity of approximately 125 megawatts. Commercial operation of the
Generation Facility commenced in April 1993. The Generation Facility includes a
lumber dry kiln facility and a 3.5 mile private natural gas pipeline.

ENCO owns and operates a portfolio of natural gas reserves in British
Columbia and Alberta, Canada, which provide a dedicated fuel supply for the
Generation Facility (collectively, the Project). ENCO produces and supplies
natural gas to the Generation Facility with off-sales to third parties. The
Generation Facility also receives a portion of its fuel under contracts with
third parties.

The Partnership produces and sells its entire electrical output to Puget
Sound Energy, Inc. ("Puget") under a 20-year electricity sales contract. The
electricity sales contract provides for the sale of electrical output at stated
prices through 2012. The stated price includes a fixed and a variable component.
The fixed and variable components are stated amounts per kilowatt hour in each
contract year. The variable component is adjusted annually based on an index of
inflation. The electricity sales contract also provides for the electrical
output of the Generation Facility to be displaced when the cost of Puget's
replacement power is less than the Company's incremental power generation costs.
The Company receives a share of the net savings from displacement. During 1997,
the Generation Facility was displaced approximately six months. Under the
electricity sales contract, the Partnership is required to be certified as a
qualifying cogeneration facility as established by the Public Utility Regulatory
Policy Act of 1978, as amended, and as administered by the Federal Energy
Regulatory Commission.

The Generation Facility produced and sold kilowatt hours of electricity to
Puget as follows:



YEAR ENDED
DECEMBER 31, KILOWATT HOURS
------------ --------------

1997..................... 439,370,000
1996..................... 1,031,900,000
1995..................... 1,026,000,000


The Partnership leases a kiln facility and sells steam under a 20-year
agreement for the purchase and sale of steam and lease of the kiln (see Note 6)
to Socco, Inc. ("Socco"), a custom lumber drying operation owned by an affiliate
of the Partnership. Steam use requirements under the agreement with Socco were
established to maintain the qualifying cogeneration facility status of the
Generation Facility.

The Partnership -- SEI assigned all its rights, title, and interest in the
Project, including the Puget contract, to the Partnership in exchange for its
Partnership interest. During 1997, all preferential distributions were fully
paid and the Partnership Agreement was amended. SEI and Whatcom are both
currently entitled to a 50% interest in the profits, losses and cash flow of the
Partnership. In addition, Whatcom is entitled to an additional allocation of
profits, losses and cash flows of a stated amount equal to 20% of forecasted
cash flows

F-58
112
SUMAS COGENERATION COMPANY, L.P. AND SUBSIDIARY

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
DECEMBER 31, 1997

for the period through June 30, 2001. After Whatcom has received cumulative
distributions representing a fixed rate-of-return of 24.5% on its equity
investment, exclusive of certain of the preferential distributions referred to
above, SEI's share of operating distributions will increase to 99.9% and
Whatcom's share of operating distributions will decrease to 0.1%.

Distributions -- Distributions of operating cash flows are permitted
quarterly after required deposits are made and minimum cash balances are met,
and are subject to certain other restrictions. For the year ended December 31,
1997, distributions totaling $36,277,051 were paid or accrued. On January 30,
1998, the December 31, 1997 accrued distributions in the amount of $1,736,612
will be paid. For the year ended December 31, 1996, distributions totaling
$4,297,970 were paid or accrued. On January 31, 1997, the December 31, 1996
accrued distributions in the amount of $3,517,491 were paid. No distributions
were paid or accrued for the year ended December 31, 1995.

Revenue recognition -- Revenue from the sale of electricity is recognized
based on kilowatt hours generated and delivered to Puget at contractual rates.
Revenue from displacement is recognized in the period to which the displacement
relates. Revenue from the sale of natural gas is recognized based on volumes
delivered to customers at contractual delivery points and rates. The costs
associated with the generation of electricity and the delivery of gas, including
operating and maintenance costs, gas transportation and royalties, are
recognized in the same period in which the related revenue is earned and
recorded.

Gas acquisition and development costs -- ENCO follows the full cost method
of accounting for gas acquisition and development expenditures, wherein all
costs related to the development of gas reserves in Canada are initially
capitalized. Costs capitalized include land acquisition costs, geological and
geophysical expenditures, rentals on undeveloped properties, cost of drilling
productive and nonproductive wells, and well equipment. Gains or losses are not
recognized upon disposition or abandonment of natural gas properties unless a
disposition or abandonment would significantly alter the relationship between
capitalized costs and proven reserves.

All capitalized costs of gas properties, including the estimated future
costs to develop proven reserves, are depleted using the unit-of-production
method based on estimated proven gas reserves as determined by independent
engineers. ENCO has not assigned any value to its investment in unproven gas
properties and, accordingly, no costs have been excluded from capitalized costs
subject to depletion.

Costs subject to depletion under the full cost include estimated future
costs of dismantlement and abandonments of ENCO of $3,560,000 in 1997,
$3,718,000 in 1996 and $3,748,000 in 1995. This includes the cost of production
equipment removal and environmental cleanup based upon current regulations and
economic circumstances. The provisions for future removal and site restoration
costs of $168,000 in 1997, $177,000 in 1996 and $193,000 in 1995 are included in
depletion expense.

Capitalized costs are subject to a ceiling test which limits such costs to
the aggregate of the net present value of the estimated future cash flows from
the related proven gas reserves. The ceiling test calculation is made by
estimating the future net cash flows, based on current economic operating
conditions, plus the lower of cost or fair market value of unproven reserves,
and discounting those cash flows at an annual rate of 10%.

Joint venture accounting -- A significant portion of ENCO's natural gas
production activities are conducted jointly with others and, accordingly, these
consolidated financial statements reflect only ENCO's proportionate interest in
such activities.

Foreign exchange gains and losses -- Foreign exchange gains and losses as a
result of translating Canadian dollar transactions and Canadian dollar
denominated cash, accounts receivable and accounts payable transactions are
recognized in the statement of income.

F-59

SUMAS COGENERATION COMPANY, L.P. AND SUBSIDIARY

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
DECEMBER 31, 1997

Cash and cash equivalents -- For purposes of the statement of cash flows,
cash and cash equivalents consist of cash and short-term investments in highly
liquid instruments such as certificates of deposit, money market accounts and
U.S. treasury bills with an original maturity of three months or less.

Concentration of credit risk -- Financial instruments, which potentially
subject the Company to concentrations of credit risk, consist primarily of cash
and short-term investments in highly liquid instruments such as certificates of
deposit, money market accounts and U.S. treasury bills with maturities of three
months or less, and accounts receivable. The Company's cash and cash equivalents
are primarily held with two financial institutions. Accounts receivable are
primarily due from Puget.

Depreciation -- The Company provides for depreciation of property, plant
and equipment using the straight-line method over estimated useful lives which
range from 7 to 40 years for plant and equipment and 3 to 7 years for furniture
and fixtures.

Amortization of other assets -- The Company provides for amortization of
other assets using the straight-line method as follows:



Organization, start-up and development costs... 5 - 30 years
Financing costs................................ 10 - 15 years
Gas contract costs............................. 20 years


Income taxes -- Profits or losses of the Partnership are allocated directly
to the partners for income tax purposes. ENCO is subject to Canadian income
taxes and accounts for income taxes on the liability method. The liability
method recognizes the amount of tax payable at the date of the consolidated
financial statements, as a result of all events that have been recognized in the
consolidated financial statements, as measured by currently enacted tax laws and
rates. Deferred income taxes are provided for temporary differences in
recognition of revenues and expenses for financial and income tax reporting
purposes.

Use of estimates -- The preparation of the consolidated financial
statements in conformity with generally accepted accounting principles requires
management to make estimates and assumptions that affect the amounts reported in
the consolidated financial statements and accompanying notes. Actual results
could differ from those estimates.

Reclassifications -- Certain 1996 amounts have been reclassified to conform
with the 1997 presentation.

============


The Partnership's loans are comprised of the Term Loans and the
Subordinated Loans. The Subordinated Loans were entered into on September 30,
1997. The Partnership's Term Loans are comprised of a fixed rate loan in the
original amount of $55,510,000 and a variable rate loan in the original amount
of $39,650,000. Interest is payable quarterly on the fixed rate loan at a rate
of 10.35%. Interest on the variable rate loan is payable monthly at either the
London Interbank Offered Rate ("LIBOR"), certificate of deposit rate or Credit
Suisse's base rate, plus an applicable margin which ranges from 0.5% to 1.25% as
stated in the loan agreement. During the year ended December 31, 1997, interest
rates on the variable rate loan ranged from 6.66% to 7.31%. The Term Loans
mature in May 2008.

The Partnership's Subordinated Loans are comprised of a fixed rate loan in
the original amount of $12,000,000, a variable rate loan in the original amount
of $8,000,000 and a Revolving Line of Credit in the

F-61

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
DECEMBER 31, 1997

amount of $1,000,000. Interest is payable quarterly on the fixed rate loan at a
rate of 7.85%. Interest is payable monthly on the variable rate loan at either
the LIBOR, certificate of deposit rate or Credit Suisse's base rate, plus an
applicable margin which ranges from 1.00% to 1.75%. During the period from
September 30, 1997 to December 31, 1997, interest rates on the variable rate
Subordinated Loan ranged from 7.16% to 7.19%. The Subordinated Loans mature in
May 2008. The Revolving Line of Credit is renewable annually at the discretion
of the Lenders and is to be used for working capital purposes. Interest is
payable monthly at either the LIBOR, certificate of deposit rate or Credit
Suisse's base rate, plus an applicable margin which ranges from 1.00% to 1.75%.
Through December 31, 1997 no borrowings were made under the Revolving Line of
Credit.

ENCO's loans are comprised of a fixed rate loan in the original amount of
$14,490,000 and a variable rate loan in the original amount of $10,350,000.
Interest is payable quarterly on the fixed rate loan at a rate of 9.99%.
Interest on the variable rate loan is payable monthly at either the LIBOR,
certificate of deposit rate or Credit Suisse's base rate, plus an applicable
margin which ranges from .5% to 1.25% as stated in the loan agreement. During
the year ended December 31, 1997, interest rates on the variable rate loan
ranged from 6.66% to 7.31%. The loans mature in May 2008.

The Partnership pays Prudential an agency fee of $50,000 per year until the
loans mature. The Partnership pays Credit Suisse an agency fee of $40,000 per
year, adjusted annually by an inflation index, until the loans mature. The loans
are collateralized by substantially all the Company's assets and interests in
the Project. Additionally, the Company's rights under all contractual agreements
are assigned as collateral. The Partnership and ENCO loans are
cross-collateralized and contain cross-default provisions.

Under the terms of the loan agreements and the deposit and disbursement
agreements with the Lenders, the Company is required to establish and fund
certain accounts held by Credit Suisse and Royal Trust as security agents. The
accounts require specified minimum deposits and funding levels to meet current
and future operating, maintenance and capital costs, and to provide certain
other reserves for payment of principal, interest and other contingencies. These
accounts are presented as restricted cash and cash equivalents and include cash,
certificates of deposit, money market accounts and U.S. treasury bills, all with
maturities of 3 months or less. The current portion of restricted cash and cash
equivalents is based on the amount of current liabilities for obligations which
may be funded from the restricted accounts. The balance of restricted cash and
cash equivalents has been classified as a non-current asset.

5. INCOME TAXES

The provision for income taxes represents Canadian taxes which consist of

7. FAIR VALUES OF FINANCIAL INSTRUMENTS

The carrying amount of all cash and cash equivalents, accounts receivable
and accounts payable reported in the consolidated balance sheet is estimated by
the Company to approximate their fair value.

The Company is not able to estimate the fair value of its debt with a
carrying amount of $133,400,004 and $117,000,003 at December 31, 1997 and 1996,

similar borrowing arrangements for similar projects because the terms of each
such financing arrangement is the result of substantial negotiations among
several parties.
