                      CALPINE CORPORATION AND SUBSIDIARIES

              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                  June 30, 1997


1.       Organization and Operation of the Company

Calpine  Corporation  ("Calpine"),  a  Delaware  corporation,  and  subsidiaries
(collectively,  the  "Company")  are  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  interests  in and  operates  natural  gas- fired  cogeneration
facilities, geothermal steam fields and geothermal power generation facilities.

2.       Summary of Significant Accounting Policies

Basis of Interim Presentation -- The accompanying interim condensed consolidated
financial  statements of the Company have been prepared by the Company,  without
audit by independent public  accountants,  pursuant to the rules and regulations
of the Securities  and Exchange  Commission.  In the opinion of management,  the
condensed   consolidated  financial  statements  include  all  and  only  normal
recurring adjustments necessary to present fairly the information required to be
set forth therein. Certain information and note disclosures normally included in
financial  statements  prepared in accordance with generally accepted accounting
principles have been condensed or omitted from these statements pursuant to such
rules and regulations and,  accordingly,  should be read in conjunction with the
audited  consolidated  financial  statements  of  the  Company  included  in the
Company's  annual report on Form 10-K for the year ended  December 31, 1996. The
results for interim  periods are not  necessarily  indicative of the results for
the entire year.

Earnings  Per Share --  Earnings  per  share is  calculated  using the  weighted
average  number  of  common  shares  and  common   equivalent   shares,   unless
antidilutive, using the treasury stock method for outstanding stock options. For
1996,  net income per share also gives effect to common  equivalent  shares from
convertible   preferred   shares  from  the  original   date  of  issuance  that
automatically  converted  to common  shares  upon  completion  of the  Company's
initial public offering in September 1996 (using the if-converted method).

In February  1997, the Financial  Accounting  Standards  Board  ("FASB")  issued
Statement  of Financial  Accounting  Standards  ("SFAS")  No. 128,  Earnings Per
Share,   which  simplifies  the  standards  for  computing  earnings  per  share
previously  found in Accounting  Principles  Board Opinion ("APBO") No. 15. SFAS
No.  128  replaces  the  presentation  of  primary  earnings  per  share  with a
presentation of basic earnings per share, which excludes dilution.  SFAS No. 128
also requires dual  presentation of basic and diluted  earnings per share on the
face of the income  statement for all entities with complex  capital  structures
and requires a reconciliation.  Diluted earnings per share is computed similarly
to fully diluted  earnings per share  pursuant to APBO No. 15. SFAS No. 128 must
be adopted for financial statements issued for periods ending after December 15,
1997, including interim periods; earlier application is not permitted.  SFAS No.
128 requires restatement of all prior-period  earnings per share data presented.
For the three and six months ended June 30, 1997, basic and diluted earnings per
share would not be materially different than the earnings per share presented in
the accompanying condensed consolidated statement of operations.

Capitalized  interest -- The Company capitalizes interest on projects during the
construction  period.  For the three and six  months  ended June 30,  1997,  the
Company  capitalized  $723,000 and $1.3  million,  respectively,  of interest in
connection  with the  construction  of the Pasadena Power Plant. No interest was
capitalized in 1996.

Derivative Financial  Instruments -- The Company engages in activities to manage
risks  associated with changes in interest  rates.  The Company has entered into
swaps to reduce  exposure to  interest  rate  fluctuations  in  connection  with
certain  debt  commitments.  The  instruments'  cash flows  mirror  those of the
underlying  exposures.  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.

                                  June 30, 1997


At June 30,  1997,  the  Company had $151.7  million of  interest  rate swaps on
non-recourse  project  financing  and $182.0  million of treasury rate locks and
enhanced  forwards on senior  notes  issued by the Company in July 1997.  During
July 1997, the Company  extinguished  non-recourse  project financing related to
$64.2  million of interest rate hedges and  terminated  one swap related to $9.2
million of hedged debt.

Reclassifications -- Prior year amounts in the consolidated  condensed financial
statements  have  been  reclassified  where  necessary  to  conform  to the 1997
presentation.

 5.      Texas Cogeneration Company Transaction

 On June 23, 1997, Calpine completed the acquisition of a 50% equity interest in
the Texas City  cogeneration  facility  (the "Texas  City Power  Plant") and the
Clear Lake  cogeneration  facility  (the "Clear  Lake Power  Plant") for a total
purchase  price of $35.4  million,  subject to final  adjustments.  The  Company
acquired its 50% interest in these plants through the  acquisition of 50% of the
capital stock of Enron Dominion  Cogen Corp.  ("EDCC") from Enron Power Corp., a
wholly owned subsidiary of Enron Corp. ("Enron").  EDCC was subsequently renamed
Texas Cogeneration Company ("TCC"). The other 50% shareholder interest in TCC is
owned by Dominion Cogen, Inc. In addition to the purchase of 50% of the stock of
TCC,  Calpine,  through its wholly owned  subsidiary,  Calpine  Finance  Company
("CFC"),  purchased from the existing  lenders the $155.6 million of outstanding
non-recourse  project  debt of 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  debt  provided  by The  Bank  of Nova  Scotia,  $14.3  million  of
borrowings  from the  revolving  line of  credit,  and $55.8  million  of equity
provided by the Company (see Notes 7 and 8 for more  information  regarding  the
revolving line of credit and the $125.0 million of non-recourse debt).

 The Company  accounts for its investment in TCC under the equity method because
control of TCC is deemed to be shared with Dominion  Cogen,  Inc. The Texas City
and Clear  Lake  Power  Plants  are  operated  by the  Company  under a one-year
contract with automatic renewal provisions.

 Texas City Power Plant -- The Texas City Power Plant is a 450 megawatt  natural
gas-fired combined-cycle cogeneration facility located in Texas City, Texas. The
Texas City Power Plant commenced commercial operation in June 1987.

 Electricity  generated by the Texas City Power Plant is sold under two separate
long-term agreements to (i) Texas Utilities Generating Company ("TUEC") under an
original  12-year power sales agreement  terminating in June 1999 and (ii) Union
Carbide  Company  ("UCC")  under  an  original  12-year  power  sales  agreement
terminating in June 1999.  Each power sales  agreement  contains  provisions for
capacity and energy. The TUEC power sales agreement provides for a firm capacity
payment for 410  megawatts.  The UCC power sales  agreement  provides for a firm
capacity payment for 20 megawatts.

                                  June 30, 1997


 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 and Trading 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 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 which are currently above spot
market prices.

 Clear Lake Power Plant -- The Clear Lake Power Plant is a 377 megawatt  natural
gas/hydrogen-fired  combined-cycle  cogeneration  facility  located in Pasadena,
Texas.  The Clear Lake Power Plant  commenced  commercial  operation in December
1984.

 Electricity  generated  by the  Clear  Lake  Power  Plant is sold  under  three
separate  long-term  agreements  to (i) Texas New Mexico Power  Company  ("TNP")
under an  original  20-year  power sales  agreement  terminating  in 2004,  (ii)
Houston Light & Power  Company  ("HL&P")  under an original  10-year power sales
agreement terminating in 2005, and (ii) Hoescht Celanese Chemical Group ("HCCG")
under an original 10-year power sales agreement  terminating in 2004. Each power
sales agreement contains provisions for capacity and energy payments.

 The  TNP  power  sales  agreement  provides  for a  firm  capacity  payment  of
production between 200 and 250 megawatts based on 98% of HL&P's tariff under its
TNP contract.  The HL&P power sales agreement provides for firm capacity payment
for 50 megawatts  for the term of the  agreement,  subject to  adjustment  under
certain specified  conditions.  The HCCG power sales agreement provides for firm
capacity payment for 35 megawatts for the term of the agreement.  The TNP energy
price is based on 98% of HL&P's tariff under its TNP contract. HL&P's and HCCG's
energy payments are based on HL&P's weighted average cost of gas, or contractual
heat rates and operations and maintenance adder.

 The natural gas for the Clear Lake Power Plant is purchased primarily from TCC,
which  receives its fuel from ECT on a tiered price basis  consisting of a fixed
priced  tier  escalating  at 5% annually  and two  index-priced  tiers.  A small
portion of the natural gas  requirements  is purchased from ECT at index prices.
In  addition,  the  facility  burns  hydrogen  provided  by HCCG,  amounting  to
approximately 5% of the Clear Lake Power Plant's total fuel requirements.

 6.      Calpine Gas Company Transaction

On January 31, 1997,  the Company  acquired  the  outstanding  capital  stock of
Montis Niger, Inc., a natural gas production  company,  and certain gas reserves
from Radnor Power, a wholly-owned  subsidiary of LFC Financial  Corp.,  for $7.1
million.  In addition,  the Company paid  $824,000 for certain  working  capital
items.  The  Company's  allocation  of the  purchase  price is  subject to final
adjustments.  Montis Niger,  subsequently  renamed to Calpine Gas Company,  owns
proven natural gas reserves and an 80-mile pipeline system which provides gas to
the Company's Greenleaf 1 and 2 Power Plants in northern California. The Company
paid  $7.6  million  in cash for a portion  of the  purchase  price and  working
capital  items,  and  recorded a $600,000  liability  for the  remainder  of the
purchase price due upon completion of certain drilling obligations.

 7.      Revolving Credit Facility

 At June 30, 1997,  the Company had a $50.0 million  credit  facility  available
with a consortium of commercial  lending  institutions which include The Bank of
Nova Scotia,  International Nederlanden U.S. Capital Corporation,  Sumitomo Bank
of  California  and Canadian  Imperial Bank of Commerce.  At June 30, 1997,  the
Company had $14.3  million of  borrowings  and $2.7 million of letters of credit
outstanding  under the credit facility.  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  (approximately  9.4% at June 30, 1997).  Interest is
paid on the last day of each interest period for such loans,  but not less often
than quarterly. The credit agreement expires in September 1999.

 On July 1, 1997,  the  Company  had an  additional  $6.0  million of letters of
credit  outstanding  related to the purchase of firm capacity and energy between
HL&P and the Clear Lake Power  Plant.  On July 8, 1997,  the Company  repaid the
$14.3 million of borrowings  with proceeds from the 8-3/4% Senior Notes Due 2007
(see Note 9).

 8.      Non-Recourse Project Financing

Note  Payable to Bank -- On June 23,  1997,  the Company  entered  into a $125.0
million  non-recourse  financing  with The Bank of Nova Scotia,  the proceeds of
which 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
debt (see Note 5). The $125.0 million non-recourse financing matures on June 22,
1998 and is  expected  to be repaid  prior to  maturity  with the  proceeds of a
planned refinancing of the $155.6 million non-recourse project debt. On June 30,
1997,  $119.3 million of borrowings were outstanding  which bear interest at The
Bank of Nova Scotia's  base rate plus an  applicable  margin or at LIBOR plus an
applicable  margin  (approximately  7.0% at June 30,  1997).  In July 1997,  the
Company utilized  existing 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 existing swap arrangement was approximately 8.4%.

 Senior-Term  and Junior Term Loans -- The Company  entered into the Senior-Term
and Junior Term Loans in connection  with the Company's  acquisition  of Calpine
Geysers  Company in 1993.  On June 30, 1997,  $102.7  million of such loans were
outstanding. 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  (see  Note 9).  In  connection  with  this  transaction,  the  Company
terminated one swap transaction and retained one swap  transaction.  The Company
had entered  into these swap  transactions  to minimize the impact of changes in
interest  rates on a portion of the Senior- Term loans and had an effective rate
of 9.9% on June 30, 1997.

 9.      Senior Notes Due 2007

 On July 8, 1997, the Company issued $200.0 million  aggregate  principal amount
of 8-3/4% Senior Notes Due 2007. The net proceeds of $195.0 million were used as
follows:  (i) $102.7 million to repay non-recourse  project financing related to
Calpine  Geysers  Company,  (ii) $6.4 million to repay a note payable to Natomas
Energy Company related to the purchase of Thermal Power Company which matures in
September 1997,  (iii) $14.3 million to repay  borrowings under The Bank of Nova
Scotia Revolving Credit Facility, (iv) $728,000 to repay a note payable to Santa
Fe Geothermal,  Inc. which matures in December 1997, and (v) approximately $70.9
million for general corporate purposes. Transaction costs incurred in connection
with the debt offering were recorded as a deferred charge and are amortized over
the  ten-year  life of the 8-3/4%  Senior  Notes Due 2007  using  the  effective
interest rate method.

 In May  and  June  1997,  the  Company  executed  five  interest  rate  hedging
transactions  related  to debt with a  notational  value of $182.0  million  and
designed to eliminate interest rate risk for the period from May 1997 to July 8,
1997 when the 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
amortized  over the life of the bond.  The  effective  interest  rate  after the
hedging transactions and the amortization of deferred costs is 9.0%.

 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.

 10.     Preferred Share Purchase Rights

 On June 5, 1997, the Board of Directors  adopted a  Stockholders  Right Plan to
strengthen the Board's  ability to protect  Calpine's  stockholders.  The Rights
Plan is designed to protect  against abusive or coercive  takeover  tactics that
are not in the best interests of Calpine 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 June 30, 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 Calpine'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 unit of
Preferred Stock will be entitled to any payment made per share of Common Stock.

 If Calpine 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
Calpine'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  Calpine'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 Calpine's Board of
Directors. The rights can be redeemed by the Board at a price of $0.01 per Right
at any time before the Rights become exercisable, and thereafter only in limited
circumstances.

 11.     Contingencies

 CPUC  Restructuring  -- Electricity  and steam sales  agreements  with PG&E are
regulated by the California Public Utilities  Commission  ("CPUC").  In December
1995,  the CPUC proposed the transition of the electric  generation  market to a
competitive  market beginning January 1, 1998, with all consumers  participating
by 2003.  Since the proposed  restructure  results in  widespread  impact on the
market structure and requires  participation and oversight of the Federal Energy
Regulatory  Commission  ("FERC"),  the CPUC  has  sought  to build a  California
consensus  involving  the  legislature,   the  Governor,  public  and  municipal
utilities  and  customers.  The  consensus has resulted in filings with the FERC
which  should  permit  both  the  CPUC and  FERC to  collectively  proceed  with
implementation of the new competitive  market structure.  On September 23, 1996,
state legislation was passed,  AB 1890 (the "Bill"),  which codified much of the
CPUC  decision  and  directed  the  CPUC  to  proceed  with   implementation  of
restructure no later than January 1, 1998. The Bill  accelerated  the transition
period to a fully  competitive  market  from five  years to four  years with all
consumers  participating  by the year 2002. The Bill provided for an electricity
rate freeze for the period of transition and mandated  through  issuance of rate
reduction  bonds a 10% rate  reduction  for  small  commercial  and  residential
customers  effective  January 1, 1998. The proposed  restructuring  provides for
phased-in customer choice (direct access),  development of a  non-discriminatory
market structure,  full recovery of utility stranded costs, sanctity of existing
contracts,  and continuation of existing public policy programs  including funds
for enhancement of in-state renewable energy  technologies during the transition
period.  In May 1997, the CPUC ruled that all utility  customers will be able to
choose their electricity  supplier beginning January 1, 1998. 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

 OVERVIEW

 Calpine is engaged in the acquisition,  development, 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 interests in 17 power
generation  facilities  and steam fields  having an aggregate  capacity of 1,874
megawatts.  In addition,  Calpine has a 240 megawatt  gas-fired power generation
facility under construction in Pasadena, Texas and pending acquisitions, subject
to the fulfillment of all required conditions, of 50% interests in two gas-fired
facilities with an aggregate capacity of 390 megawatts in Virginia and Florida.

 On January 31, 1997, the Company  acquired the Calpine Gas Fields (formerly the
Montis  Niger Gas Fields) for a total price of  approximately  $7.1 million plus
$824,000  for certain  working  capital  items.  The Calpine Gas Fields have 9.7
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 a  240  megawatt
gas-fired  cogeneration project at the Phillips Houston Chemical Complex ("HCC")
located in Pasadena,  Texas (the "Pasadena Cogeneration  Project").  The Company
has entered  into an agreement to supply HCC with  approximately  90  megawatts,
with  the  remainder  of  available  electricity  output  to be  sold  into  the
competitive  market.  The Pasadena  Cogeneration  Project is the first  merchant
power plant to be financed with non-recourse project debt and is scheduled to be
operational in 1998. In February 1997, the Company  announced the development of
a 480 megawatt  gas-fired  cogeneration  project in Sutter  County,  in northern
California (the "Sutter Cogeneration Project").  The Sutter Cogeneration Project
would  be  northern   California's   first  merchant  power  plant.  The  Sutter
Cogeneration  project 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 May 16, 1997, the Company  entered into  agreements to acquire 50% interests
in the 240 megawatt Gordonsville Power Plant located west of Richmond,  Virginia
and the 150 megawatt Auburndale Power Plant located outside of Orlando, Florida.
The Company  currently  expects to complete the acquisition upon the fulfillment
of all required conditions. However, there can be no assurances that the Company
will successfully complete this acquisition.


                                     - 13 -





 On June 23,  1997,  the  Company  completed  the  acquisition  of a 50%  equity
interest in 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
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 debt  associated  with the
Texas City and Clear Lake Power Plants.  The Company  accounts for its 50% share
of  earnings  from the Texas City and Clear Lake Power  Plants  under the equity
method  of   accounting   and  such   earnings  are  included  in  "income  from
unconsolidated investments in power projects".

 Included in the results of  operations  for the three and six months ended June
30, 1997 are the King City and Gilroy  Power Plants which each have a generating
capacity of 120  megawatts.  The King City Power Plant has been  included in the
Company's  consolidated  results of operations  since the May 2, 1996  effective
date of the operating lease, and the Gilroy Power Plant since its acquisition on
August 29, 1996.  As scheduled by PG&E and in accordance  with their  respective
power sales  agreements,  the King City and Gilroy Power Plants did not generate
electricity  during the four months ended April 30,  1997.  As  scheduled,  both
power plants resumed operation on May 1, 1997.

 Each of the Company's  consolidated power plants produces  electricity for sale
to a utility or, in certain  instances,  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. The Company has a net interest of 421 megawatts of the aggregate
capacity generated by nine power plants that deliver  electricity to Pacific Gas
and Electric Company ("PG&E") under separate  long-term power sales  agreements.
Each of these agreements provides for both capacity payments and energy payments
for the term of the  agreement.  During the initial  ten-year  period of certain
agreements, PG&E pays a fixed price for each unit of electrical energy according
to schedules set forth in such agreements (which represent 17%, or 73 megawatts,
of such  net  interest).  The  fixed  price  periods  under  these  power  sales
agreements expire at various times from 1998 through 2000. 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 PG&E's then avoided cost of energy,  which is determined  and published  each
month by the utility.  The term "avoided cost" refers to the  incremental  costs
that an electric  utility  would incur to produce or purchase an amount of power
equivalent to that  purchased from QFs. On December 9, 1996, the CPUC approved a
new methodology for the  calculation of short-run  avoided cost ("SRAC"),  which
was  effective  retroactive  to  October  1,  1996 and will  continue  until the
independent power exchange has commenced operations and is functioning properly.
The independent power exchange is scheduled to commence operations on January 1,
1998.  Thereafter,  the  SRAC  will  become  the  energy  clearing  price of the
independent power exchange. The currently prevailing SRAC is substantially lower
than the fixed energy prices under these power sales agreements and is generally
expected to remain so. While SRAC does not affect  capacity  payments  under the
power  sales  agreements,   in  the  event  that  the  SRAC  does  not  increase
significantly,  the Company's energy revenues under these power sales agreements
would 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  cannot  predict the likely level of SRAC prices at the
expiration of the fixed price periods. The majority of the capacity revenues are
paid  during  the  months  of May  through  October.  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 facilities that supply
electricity.  For the three and six months ended June 30, 1997,  such facilities
experienced  a reduced  amount of  curtailment  compared to the same  periods in
1996. Due to an amendment to the power sales  contracts  executed in April 1997,
the Company  currently does not expect  curtailment  during the remainder of the
term of the power sales agreements for these power plants.


                                     - 14 -





 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
envisions  commencement of deregulation and implementation of customer choice of
electricity supplier by January 1, 1998. Legislation  implementing this decision
was  adopted  in  September  1996.  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 operation.  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 DATA

Electric  energy and  capacity  revenue  increased  for the three and six months
ended June 30, 1997  compared to the same periods in 1996,  primarily due to the
Gilroy and King City Power Plants.

 Megawatt hours produced by power plants  increased in 1997 compared to the same
periods in 1996,  primarily due to 121,000 megawatt hours produced by the Gilroy
Power Plant for the three and six months ended June 30,  1997.  The Gilroy Power
Plant was  acquired by the Company in August  1996.  During the six months ended
June 30, 1997,  Greenleaf 1 Power Plant  production  declined by 51,000 megawatt
hours as it did not operate for the period from  January 1 to February  26, 1997
due to flooding in the vicinity of the power plant.  The average energy rate per
kilowatt hour produced for all power plants  declined for the three months ended
June 30, 1997 compared to the same period in 1996, primarily due to lower priced
Gilroy energy production. The average energy rate per kilowatt hour produced for
all power plants  increased  for the six months ended June 30, 1997  compared to
the same period in 1996,  reflecting  increases in the average energy prices per
kilowatt hour produced during 1997 at certain gas-fired power plants.

 Steam field  megawatt  hours  produced  increased  for the three and six months
ended June 30, 1997 compared to the same periods in 1996,  primarily due to more
production and less curtailment  during 1997. During 1996, PG&E Unit 13 was shut
down  from  March  23 to May 25 for  installation  of a new  turbine  rotor.  In
addition,  the SMUDGEO#1 power plant was shut down from April 21 to June 5, 1996
for a scheduled overhaul. The average 

                                     - 15 -





energy rates per kilowatt hour  produced  during 1997 were lower than the prices
for the comparable periods in 1996,  primarily due to lower prices in accordance
with the power sales agreements.

 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 either (i) to income from operations  (determined in
accordance with generally accepted accounting  principles) or (ii) to cash flows
from  operating  activities  (determined in accordance  with generally  accepted
accounting principles).

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


 RESULTS OF OPERATIONS

 Three and Six Months Ended June 30, 1997 Compared to Three and Six Months Ended
 June 30, 1996

 Revenue.  Total revenue was $67.7 million and $107.0  million for the three and
six months ended June 30, 1997  compared to $50.3  million and $82.0 million for
the comparable  periods in 1996.  Electricity and steam sales revenue  increased
35% and 34% to $62.6  million  and $96.3  million  for the three and six  months
ended  June 30,  1997  compared  to $46.3  million  and  $72.0  million  for the
comparable  periods in 1996.  The  increase  for the three months ended June 30,
1997 was  primarily  due to $11.0 million of revenue from the Gilroy Power Plant
acquired in August 1996, $1.4 million of higher revenue from the King City Power
Plant  (included  in Company  operations  since May 1996),  and $3.4  million of
higher revenue from the Company's  geothermal  facilities.  The increase for the
six months  ended June 30, 1997 was  primarily  due to $13.5  million of revenue
from the Gilroy Power Plant,  $2.6 million of higher  revenue from the King City
Power Plant, $5.9 million of higher revenue from the Company's  geothermal power
plants,  and $2.4 million due to increased prices or production at other Company
gas-fired power plants. As scheduled,  the King City and Gilroy Power Plants did
not generate  electrical  energy and did not earn energy revenue during the four
months ended April 30, 1997. Included in geothermal revenue are revenue from the
West Ford Flat and Bear Canyon Power Plants which  increased by $1.8 million and
$3.7  million for the three and six months  ended June 30, 1997  compared to the
same periods in 1996,  primarily due to increased kilowatt hour generation.  The
West Ford Flat and Bear Canyon  Power  Plants were  curtailed  under their power
sales agreements for  approximately  $251,000 and $1.9 million of revenue during
the three and six months ended June 30,  1997,  compared to  approximately  $2.3
million and $4.9  million of revenue  during the same  periods in 1996.  Thermal
Power  Company also  contributed  $859,000 and $1.8 million more revenue for the
three and six months  ended June 30,  1997 than the same  periods in 1996 due to
increased steam sales under the alternative  pricing agreement entered into with
PG&E in March  1996.  Service  contract  revenue  decreased  39% and 35% to $1.7
million and $2.8 for the three and six months  ended June 30,  1997  compared to
$3.5 and $5.4 million  primarily due to overhauls at the Aidlin and Agnews power
plants during 1996.  Income from  unconsolidated  investments  in power projects
increased  to $2.1  million and $4.2  million for the three and six months ended
June 30,  1997  compared to $298,000  and $1.7  million for the same  periods in
1996. The increase is primarily attributable to increased equity income from the
Company's investment

                                     - 16 -





in Sumas Cogeneration Company, L.P. ("Sumas").  The increase in Sumas income was
primarily due to lower  operating costs in 1997 as the plant operated at minimum
capacity  from  February  to June 1997 in  accordance  with the the power  sales
agreement.  However,  Sumas  also  received a higher  price for energy  sold and
certain other  payments from Puget Sound Power and Light Company under the power
sales agreement. In addition, operating costs were lower in 1997 Interest income
on loans to power projects increased 41% and 4% to $1.3 million and $3.0 million
for the three and six months  ended June 30, 1997  compared to $920,000 and $2.8
million for the comparable periods in 1996, primarily related to interest income
on the  loans to the sole  shareholder  of Sumas  Energy,  Inc.,  the  Company's
partner in the Sumas project.

 Cost of revenue.  Cost of revenue  increased  24% and 32% to $37.2  million and
$67.8 million for the three and six months ended June 30, 1997 compared to $30.0
million and $51.3 million for the  comparable  periods in 1996. The increase was
primarily due to plant  operating,  depreciation  and operating  lease  expenses
attributable  to the  operations  of the King City and Gilroy Power Plants which
have been included in the Company's  operations since May 2, 1996 and August 29,
1996, respectively.

 Project development expenses increased to $1.8 million and $3.9 million for the
three and six months  ended June 30, 1997  compared to $894,000 and $1.4 million
for the same  periods  in 1996.  The  increase  was due  primarily  to  expanded
business acquisition and development activities.

 General  and  administrative  expenses.  General  and  administrative  expenses
increased  38% and 46% to $4.4  million  and $8.6  million for the three and six
months  ended June 30, 1997  compared to $3.2  million and $5.9  million for the
same periods in 1996.  The increase in 1997 was due to additional  personnel and
related expenses necessary to support the Company's expanded operations.

 Interest expense. Interest expense increased to $13.2 million and $26.1 million
for the three and six months ended June 30, 1997  compared to $10.4  million and
$18.7 million for the comparable periods in 1996. The 27% increase for the three
months ended June 30, 1996 compared to the same period in 1996 was  attributable
to $2.4 million of interest on debt  related to the Gilroy Power Plant  acquired
in August  1996 and $2.4  million of  increased  interest  on the 10 1/2% Senior
Notes Due 2006 issued in May 1996,  offset by  $723,000 of interest  capitalized
for the  construction of the Pasadena Power Plant and a $1.5 million decrease in
interest  expense  primarily as a result of  repayments  of principal on certain
non-recourse  project  financings  and  other  short-term  borrowings.  The  40%
increase for the six months  ended June 30, 1997  compared to the same period in
1996 was  attributable to $7.3 million of increased  interest expense related to
the 10 1/2%  Senior  Notes  Due 2006  issued  in May 1996  and $4.7  million  of
interest  on debt  related to the Gilroy  Power Plant  acquired in August  1996,
offset by $1.3  million of  interest  capitalized  for the  construction  of the
Pasadena Power Plant and a $3.2 million decrease in interest  expense  primarily
as  a  result  of  repayments  of  principal  on  certain  non-recourse  project
financings and other short-term borrowings.

 Other income, net. Other income, net increased to $4.3 million and $7.9 million
for the three and six months  ended June 30, 1997  compared to $2.2  million and
$2.8 million for the same periods in 1996 due to interest  earned on higher cash
and cash  equivalent  balances  and  interest  income  earned on the  collateral
securities for the King City Power Plant.

 Provision for income taxes. The effective income tax rate was approximately 39%
and 36% for the three and six months ended June 30, 1997. The effective tax rate
differs  from the federal  statutory  rate due to the effect of state tax rates
offset by depletion in excess of tax basis benefits at the Company's  geothermal
facilities.  The effective rate for the three and six months ended June 30, 1996
was 41% which approximates federal and state statutory tax rates.

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

Operating  activities  provided  $16.8 million for the six months ended June 30,
1997  consisting of  approximately  $5.4 million of net income from  operations,
$1.9  million in  deferred  income  taxes,  $21.8  million of  depreciation  and
amortization,  $15.7 million net decrease in operating  assets and  liabilities,
$6.1 million partnership  distribution from unconsolidated  investments in power
projects and $1.6 million distribution from Coperlasa, offset by $4.2 million of
income from unconsolidated investments in power projects.

Investing  activities  used $220.5  million during the six months ended June 30,
1997,  primarily due to $192.0 million for the acquisition of Texas Cogeneration
Company and the related notes receivable,  $39.7 million of capital expenditures
related to the construction of the Pasadena Power Plant,  $17.9 million of other
capital  expenditures,  $7.6 million for the acquisition of Calpine Gas Company,
offset by a $5.7  million  loan  payment  from  Texas  City and Clear Lake Power
Plants,  $5.3 million of collateral  security  maturities in connection with the
King City Power Plant and a $29.5 million decrease in restricted cash, primarily
related to the Pasadena Power Plant.

Financing activities provided $127.1 million of cash during the six months ended
June 30, 1997  consisting of $139.3 million of borrowings for the acquisition of
Texas Cogeneration  Company and the related debt, $3.3 million of borrowings for
contingent  consideration in connection with the acquisition of the Gilroy Power
Plant, offset by $15.9 million repayment of non-recourse project debt.

As of June 30, 1997,  cash and cash  equivalents  were $23.4 million and working
capital was a negative  $77.2  million.  For the six months ended June 30, 1997,
cash  and cash  equivalents  decreased  by $76.6  million  and  working  capital
decreased by $173.4  million as compared to the period ended  December 31, 1996.
The decrease in working  capital is primarily  due to the use of available  cash
and  proceeds  from a  non-recourse  project  financing  due  June  1998  in the
acquisition  of  Texas   Cogeneration   Company  and  in  the  purchase  of  the
non-recourse project financing of the Texas City and Clear Lake Power Plants.

As a developer, owner and operator of power generation projects, 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 June 30, 1997,  the Company had  outstanding  $105.0 million of 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 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.
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 include dividends and certain  purchases and investments,  incur
additional indebtedness and engage in certain transactions. On July 8, 1997, the
Company  issued  $200.0  million of 8 3/4% Senior Notes Due 2007 which mature on
July 15, 2007 and bear interest payable  semi-annually of January 15 and July 15
of each year,  beginning  January 1, 1998. Of the $195.0 million of net proceeds
from the sale of the Senior  Notes,  the  Company  repaid  approximately  $124.1
million of existing  indebtedness  (see Note 9 for use of  proceeds  and further
information).  The  Company  anticipates  that a portion  of the  remaining  net
proceeds will be used to finance potential future acquisitions.

                                     - 18 -





At June 30,  1997,  the  Company  had  $301.5  million of  non-recourse  project
financing  associated with power  generating  facilities and steam fields at the
West Ford Flat Power Plant,  the Bear Canyon  Power Plant,  the PG&E Unit 13 and
Unit 16 Steam Fields,  the SMUDGEO #1 Steam Fields,  the Greenleaf 1 and 2 Power
Plants and the Gilroy Power Plant.  Utilizing a portion of the net proceeds from
the sale of the 8 3/4%  Senior  Notes  Due  2007,  on July 8,  1997 the  Company
extinguished  $102.7 million of non-recourse  project  financing  related to the
Company's  geothermal  assets.  After  such  early  extinguishment,  the  annual
maturities  for all  non-recourse  project  financing  were $8.3 million for the
remainder of 1997, $9.7 million for 1998,  $8.7 million for 1999,  $10.4 million
for 2000, $10.6 million for 2001 and $149.8 million thereafter.

At June 30, 1997, the Company had $119.3 million of non-recourse borrowings from
The Bank of Nova  Scotia  in  connection  with  the  acquisition  of 50%  equity
interests  in the Texas City and Clear Lake Power  Plants.  Such debt matures on
June 22, 1998 and is expected to be repaid  prior to maturity  with the proceeds
of a planned refinancing of the $155.6 million non-recourse project debt owed by
the Texas City and Clear Lake Power Plants.

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 LIBOR or at The Bank of Nova Scotia
base rate plus a mutually agreed margin. At June 30, 1997, the Company had $14.3
million  of  borrowings  outstanding  and $2.7  million  of  letters  of  credit
outstanding under the revolving credit facility (see Note 7). The Company repaid
the $14.3 million of borrowings on July 8, 1997.  The Bank of Nova Scotia 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  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 June 30,  1997,  the Company had no  borrowings  under this  working
capital  line and  $974,000 of letters of credit  outstanding.  Borrowings  bear
interest at prime plus 1%.

At June 30, 1997, the Company had outstanding a non-interest  bearing promissory
note to Natomas  Energy  Company in the amount of $6.5  million  representing  a
portion of the September 1994 purchase price of Thermal Power Company. This note
had been discounted to yield 8% per annum and was due September 9, 1997. On July
10, 1997,  the Company  extinguished  this debt with the payment of $6.4 million
(see Note 9).

The  Company  intends  to  continue  to  seek  the use of  non-recourse  project
financing  for new  projects,  where  appropriate.  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 June 30, 1996, the Company had commitments  for capital  expenditures in 1997
totaling $44.2 million related to various projects at its geothermal facilities.
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.  Capital expenditures for the six months
ended June 30, 1997 of $57.6 million included $39.7 million for the construction
of the Pasadena Power Plant,  $8.2 million related to the geothermal  facilities
and the remaining $9.7 million at the gas-fired power plants.

The Company  continues to pursue the  acquisition  and  development of new power
generation projects. The Company expects to commit significant capital in future
years for the  acquisition  and  development  of these  projects.  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  and  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, 1997.

Impact of Recent Accounting Pronouncement

In  February  1997,  the FASB issued SFAS No.  128,  Earnings  Per Share,  which
simplifies the standards for computing  earnings per share  previously  found in
APBO No. 15. SFAS No. 128  replaces  the  presentation  of primary  earnings per
share with a presentation of basic earnings per share,  which excludes dilution.
SFAS No. 128 also requires dual  presentation of basic and diluted  earnings per
share on the face of the income  statement for all entities with complex capital
structures and requires a reconciliation. Diluted earnings per share is computed
similarly to fully diluted  earnings per share pursuant to APBO No. 15. SFAS No.
128 must be adopted for  financial  statements  issued for periods  ending after
December  15,  1997,  including  interim  periods;  earlier  application  is not
permitted.  SFAS No. 128 requires  restatement of all prior-period  earnings per
share  data  presented.  For the three  months  ended June 30,  1997,  basic and
diluted earnings per share would not be materially different to the earnings per
share  presented  in  the  accompanying   condensed  consolidated  statement  of
operations.

In June 1997, the FASB issued SFAS No.130, Reporting Comprehensive Income, which
establishes  standards for reporting and display of comprehensive income and its
components   (revenues,   expenses,   gains  and   losses)  in  non-   condensed
general-purpose  financial  statements.  SFAS No.130 requires  classification of
other  comprehensive  income by their nature in a financial  statement,  and the
display of the accumulated balance of other comprehensive income separately from
retained  earnings and  additional  paid-in  capital in the equity  section of a
statement  of  financial  position.  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 the way
public business  enterprises  report  information  about  operating  segments in
annual financial  statements and requires that those 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.
