                      CALPINE CORPORATION AND SUBSIDIARIES
              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                               September 30, 1998

Note 1.    Organization and Operation 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  interests  in and  operates  natural  gas-fired  power  plants,
geothermal power plants and geothermal steam fields.

Note 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 the 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, 1997. The results for
interim  periods are not  necessarily  indicative  of the results for the entire
year.

Capitalized  Interest - The Company capitalizes  interest on projects during the
development  and  construction  period.  For the nine months ended September 30,
1998 and 1997, the Company capitalized $6.9 million and $2.6 million of interest
in connection with the development and construction of power plants.

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 anticipation
of 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 being amortized over the respective
lives of the underlying transaction or recognized immediately if the transaction
is  terminated  earlier  than  initially  anticipated.  Gains and  losses on any
instruments  not meeting the above criteria would be recognized in income in the
current period.  Subsequent gains or losses on the related financial  instrument
are  recognized  in  income in each  period  until the  instrument  matures,  is
terminated or is sold.

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  financial  instruments to
manage its exposure to commodity price fluctuations. On September 30, 1998, CPSC
held swap  contracts  with several  entities in order to ensure  fulfillment  of
certain  sales  contracts  for the period from  September  30, 1998 to March 31,
1999.

At September  30, 1998,  CPSC had no net open  positions  which would expose the
Company to risks of fluctuating  market prices.  These types of risks could have
an adverse impact on the Company's  financial position or results of operations.
However,  the Company  actively  manages its positions,  and it is the Company's
policy to not have any open  positions.  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  on  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.

                               September 30, 1998

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.

Reclassifications - Prior period amounts in the condensed consolidated financial
statements  have  been  reclassified  where  necessary  to  conform  to the 1998
presentation.

Impact  of  Recent  Accounting  Pronouncements  - In April  1998,  the  American
Institute of Certified Public Accountants ("AICPA") issued Statement of Position
("SOP") No.  98-5,  "Reporting  on the Costs of Start-Up  Activities,"  which is
effective for financial statements for fiscal years beginning after December 15,
1998. For purposes of this SOP, start-up activities are defined broadly as those
one-time activities related to opening a new facility,  conducting business in a
new territory,  conducting business with a new class of customer or beneficiary,
initiating  a new  process  in an  existing  facility,  or  commencing  some new
operation.  Start-up  activities  include activities related to organizing a new
entity (commonly referred to as organization  costs).  Although earlier adoption
is encouraged, the Company has not yet quantified or determined the timing of or
method of the adoption.

In June 1998,  the  Financial  Accounting  Standards  Board issued  Statement of
Financial  Accounting  Standards  ("SFAS") No. 133,  "Accounting  for Derivative
Instruments and Hedging Activities".  The Statement  establishes  accounting and
reporting  standards,  requiring every derivative  instrument be recorded in the
balance  sheet as either an asset or liability  measured at its fair value.  The
Statement  requires  that changes in the  derivative's  fair value be recognized
currently in earnings unless specific hedge accounting criteria are met. Special
accounting  for  qualifying  hedges  allows a  derivative's  gains and losses to
offset related results on the hedged item in the income  statement,  and require
that a company formally  document,  designate,  and assess the  effectiveness of
transactions that receive hedge accounting.

SFAS No. 133 is effective for fiscal years  beginning  after June 15, 1999.  The
Statement must be applied to derivative  instruments  and to certain  derivative
instruments  embedded  in  hybrid  contracts  that  were  issued,  acquired,  or
substantively modified after December 31, 1997.

The Company  has not yet  analyzed  the impact of  adopting  SFAS No. 133 on the
financial  statements  and has not  determined  the  timing  of or method of the
adoption of SFAS No. 133.  However,  the Statement could increase  volatility in
earnings.

Note 3.    Accounts Receivable

At  September  30, 1998,  accounts  receivable  totaled  $100.8  million,  which
included $4.6 million receivable from related parties.  Accounts receivable from
related  parties at  September  30,  1998 and  December  31, 1997  included  the

(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.

(2) On March 31, 1998, the Company  acquired the remaining 50% interest in Texas
Cogeneration Company.

Note 5.    Repayment of Non-Recourse Project Financing

On March 31, 1998,  the Company  repaid $89.6 million to The Bank of Nova Scotia
which  represented  the  outstanding  balance on the original  $125.0 million of
non-recourse project financing utilized to fund a portion of the purchase of the
original 50% interest in Texas Cogeneration  Company, and the purchase of $155.6
million of notes receivable from the related  projects.  The Company  refinanced
the non-recourse  project  financing with a portion of the net proceeds from the
initial $300.0  million  offering of 7-7/8% Senior Notes Due 2008 ("Senior Notes
Due 2008"), (See Note 11).

Note 6.    Tiverton Transaction

On September 28, 1998,  the Company  entered into a partnership  agreement  with
Energy  Management,  Inc.  ("EMI")  to acquire an  ownership  interest  in a 265
megawatt  gas-fired plant under development in Tiverton,  Rhode Island.  EMI and
the Company will be co-general partners for this project, with EMI acting as the
Managing  General  Partner.  The Company invested $40.0 million of equity in the
merchant power plant, which is scheduled to go into commercial  operation in May
2000.  The Company will  receive up to 63% of all cash and income  distributions
from the  Tiverton  project  until it receives a 10.5%  pre-tax  rate of return.
Thereafter, the Company will receive 50% of all distributions.

gas-fired power plant from the Dow Chemical  Company  ("Dow") for  approximately
$12.7  million.  The  power  plant is  located  at Dow's  Pittsburg,  California
chemical  facility.  The  Company's  Pittsburg  Power  Plant  will sell up to 18
megawatts of electricity to Dow under a ten-year power sales agreement, with the
balance  sold to Pacific Gas & Electric  Company  under an existing  power sales
agreement.  In addition,  the Company will sell approximately  200,000 lbs/hr of
steam to Dow and to USS-POSCO Industries' nearby steel mill.

Note 9.    Texas City and Clear Lake Transaction

On March 31, 1998, the Company  acquired the remaining 50% interest in the Texas
City Power  Plant and the Clear Lake Power  Plant for a purchase  price of $52.8
million in cash. The Company has certain contingent purchase payments that could
approximate  2.2% of project revenue  beginning in the year 2000,  increasing to
2.9% in 2002.  The Company  acquired the remaining  interests in these plants by
purchasing the capital stock of Texas Cogeneration Company ("TCC") from Dominion
Cogen,  Inc. ("DCI").  As part of this transaction,  the Company now owns a 7.5%
interest in the Bayonne Power Plant, a gas-fired power plant located in Bayonne,
NJ. The Company  purchases  the  majority of its natural gas for the Texas power
plants  from  Enron  Capital & Trade  Resources  Corp.  In  connection  with the
acquisition,  the  Company  paid  approximately  $105.3  million to  restructure
certain gas contracts with Enron Capital & Trade Resources Corp.

The purchase of the capital stock from DCI and the payment for the restructuring
of certain gas contracts were funded

with a portion of the net  proceeds  from the  issuance of the Senior  Notes Due
2008 (See Note 11). The acquisition was accounted for as a purchase.

On June 23,  1997,  the Company  acquired  the initial 50% interest in the Texas
City and Clear Lake Power Plants  through the  acquisition of 50% of the capital
stock of  Enron/Dominion  Cogen Corp.  ("EDCC") from a subsidiary of Enron Corp.
EDCC was  subsequently  renamed  TCC. In addition to the purchase of the capital
stock of TCC in June 1997, the Company purchased from the project lenders $155.6
million  of  outstanding  debt on the Texas  City and Clear  Lake  Power  Plants
(approximately $53.0 and $102.6 million, respectively).

The following  represents unaudited pro forma results of operations for the year
ended  December  31,  1997 and for the nine months  ended  September  30,  1998,

Note 10.   Bethpage Transaction

On February 5, 1998,  the Company  acquired  the  remaining  55% interest in TBG
Cogen Partners ("TBG Cogen").  The partnership  owns the Bethpage Power Plant, a
57 megawatt  gas-fired  cogeneration  facility  located on Long Island,  NY. The
total  purchase  price of $5.0  million  consisted  of: (i) a $4.6  million cash
payment and (ii) a $375,000 option applied toward the purchase, subject to final
adjustments. The Company was also assigned all of General Electric's interest as
operator of the Bethpage Power Plant.

Upon the  acquisition  of the remaining 55%  interest,  the Company  assumed the
outstanding  debt of TBG Cogen. On March 31, 1998, the Company made a payment to
Toronto  Dominion,  Inc. of approximately  $38.2 million to pay off the existing
project debt, accrued interest,  and a related interest rate swap with a portion
of the net  proceeds  from  the  Senior  Notes  Due  2008  (See  Note  11).  The
acquisition was accounted for as a purchase.

Note 11.   Financial Instruments

On March 5, 1998,  the Company  terminated  an existing  forward  Treasury  bond
entered  into in  February  1998 in  anticipation  of the Senior  Notes Due 2008
offering. The Company closed its position prior to the pricing date of the debt,
which  resulted  in a gain  of  $2.3  million.  The  gain  was  deferred  and is
recognized  as an offset to  interest  expense  over the  remaining  life of the
Senior Notes Due 2008 using the effective interest method.

On March 31,  1998,  the  Company  completed  its Rule 144A  offering  of $300.0
million Senior Notes Due 2008. After deducting  discounts to initial  purchasers
and expenses of the offering, the net proceeds from the sale of the Senior Notes
Due 2008 were approximately  $293.5 million.  Proceeds from the Senior Notes Due
2008 were used as follows:  (i) $52.8  million for the purchase of the remaining
50% interest in TCC (See Note 9), (ii) $105.3 million for the  restructuring  of
certain gas contracts  associated with the TCC  acquisition  (See Note 9), (iii)
$89.6  million  for  the  outstanding  principal  on  the  non-recourse  project
financing  provided  by The Bank of Nova  Scotia  (See Note 5),  and (iv)  $38.2
million  for the  outstanding  debt on the  Bethpage  Power Plant (See Note 10).
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 Senior Notes
Due 2008 using the effective interest rate method.  Subsequent to this offering,
on July 24, 1998, the Company  completed the Rule 144A offering of an additional
$100.0  million  Senior Notes Due 2008,  which mature on April 1, 2008, and bear
interest payable  semi-annually on April 1 and October 1 of each year commencing
October 1, 1998. After deducting discounts to initial purchasers and expenses of
the  offering,  the net proceeds from the sale of the Senior Notes Due 2008 were
approximately  $98.8 million.  With the net proceeds,  the Company has repaid in
full the non-recourse  project  financing

on  the  Pasadena  1  Power  Plant  of  $52.1   million  to  ING  Capital  Corp.
Additionally,  the Company  expects to use  approximately  $30.0 million for the
remaining construction costs on the Pasadena 1 Power Plant. The remainder of the
net  proceeds  will be  used  for  the  acquisition  and  development  of  power
generation  facilities and 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 Senior Notes Due 2008 using the
effective interest rate method.

On April 9, 1998, the Company  terminated an existing interest rate swap related
to $102.6  million  of debt for the Clear  Lake Power  Plant  which the  Company
purchased on June 23, 1997. The Company paid approximately $3.7 million to close
its  position  with  The Bank of Nova  Scotia  and  recorded  a  purchase  price
adjustment of approximately  $2.3 million which was the market value of the swap
on June 23, 1997.  The remaining $1.4 million was deferred and is amortized over
the remaining life of the swap.

Note 12.   Revolving Credit Facility and Line of Credit

On May 15, 1998, the Company  replaced its $50.0 million credit  facility with a
$100.0  million  credit  facility,  which has a three-year  term expiring in May
2001.  The  Company's  $100.0  million  credit  facility is available  through a
consortium of commercial  lending  institutions  with The Bank of Nova Scotia as
agent. At September 30, 1998, the Company had no borrowings and $26.7 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.  Interest
is paid on the last day of each  interest  period for such  loans,  but not less
often than quarterly.

Note 13.   Earnings per Share

Basic  earnings per share were computed by dividing net earnings by the weighted
average number of common shares  outstanding for the period. The dilutive effect
of the potential  exercise of outstanding  options to purchase  shares of common
stock is calculated using the treasury stock method. The reconciliation of basic
earnings per share to diluted earnings per share is shown in the following table
(dollars in thousands except share data).

For the three  months  ended  September  30,  1998,  the Company  recognized  an
extraordinary  charge of  $339,000  or $0.01 per share  (net of tax  benefit  of
$207,000) as a result of the  repurchase  of $4.3 million of the 10-1/2%  Senior
Notes Due 2006. Year-to-date the Company has recognized a $641,000 extraordinary
charge (net of tax benefit of $441,000),  for the  repurchase of $8.3 million of
the 10-1/2%  Senior  Notes Due 2006.  The notes were  redeemed at a premium plus
accrued interest to the date of repurchase.

Unexercised  employee stock options to purchase  49,000 and 47,500 shares of the
Company's common stock during the nine months ended September 30, 1998 and 1997,
respectively, were not included in the computation of diluted shares outstanding
because such inclusion would be anti-dilutive.

Note 14.   CCNG Investments Transaction

On May 1, 1998, the Company granted CCNG  Investments,  L.P. ("CCNG") options to
purchase  1.1 million  shares of the  Company's  common stock  ("Stock  Purchase

value.  CCNG did not  exercise  any part of this right.  Additionally,  prior to
December 31, 1998,  CCNG has the one-time  right to purchase from the Company up
to 50,000 shares of common stock at a price of $17-7/8 per share.  To date, CCNG
has not exercised its option to purchase any shares.

Note 15.   Commitments and Contingencies

Royalties and Leases - The Company is committed under several  geothermal leases
and  right-of-ways,  easements and surface  agreements.  The  geothermal  leases
generally provide for royalties based on production  revenue with reductions for
property taxes paid.  The  right-of-ways,  easements and surface  agreements are
based on flat rates and are not material.

Office and Equipment  Leases - The Company  leases its corporate  office,  Santa
Rosa,  Houston,  and Boston office facilities and certain office equipment under
non-cancelable  operating  leases  expiring  through 2002.  Future minimum lease
payments  under  these  leases  for  the  remainder  of 1998  are  approximately
$360,000.

Greenleaf Operating Lease - In August 1998, the Company entered into a sales and
leaseback transaction for certain plant and equipment of its Greenleaf 1&2 Power
Plants,  two 49.5 megawatt gas-fired  cogeneration  facilities located in Sutter
County,  California for a net book value of $108.6  million.  Under the terms of
the agreement,  the Company received  approximately $559,000 for the sale of all
its rights,  title and interest in the stock of Calpine  Greenleaf  Corporation,
and transferred all non-recourse project financing of $71.6 million and deferred
taxes  of  $39.8  million.  Annual  rent  payments  under  the  operating  lease
agreements  for 1998 are  approximately  $4.9 million with future rent  payments
from  1999 to 2004  continuing  at $9.0  million  per  year  and  $71.6  million
thereafter through June 2014. A gain of $2.8 million was recorded on the balance
sheet and is being amortized and recognized over the term

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.  At September 30, 1998 basic rent payments were $2.9
million each for 1997 and 1998, respectively.  Future payments from 1998 to 2001
will equal $2.9 million per annum, and $24.4 million thereafter through December
2009.  Contingent  rent expense for the nine months ended September 30, 1998 and
1997 was $398,000 and $483,000 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 distributed to the
lessor and 40% is retained by the Company.

King City Operating  Lease - In April 1996, the Company entered into a long-term
operating lease with BAF Energy, A California Limited Partnership ("BAF"), for a
120 megawatt natural  gas-fired  cogeneration  power plant located in King City,
California. The power plant generates electricity for sale to PG&E pursuant to a
long-term PSA through 2019 and provides steam to a vegetable  processing  plant.
Under the terms of the lease the Company makes semi-annual lease payments to BAF
on each  February 15 and August 15, a portion of which is  supported  by a $89.8
million  collateral  fund owned by the Company.  The collateral fund consists of
investment  grade and U.S.  Treasury  Securities that mature serially in amounts
equal to a portion of the lease  payment.  The  collateral  fund  securities are
classified as held-to-maturity investments. As of September 30, 1998 future rent
payments are $4.8 million for 1998,  $19.4  million for 1999,  $20.1 million for
2000, $20.8 million for 2001, and $183.2 million thereafter.

Legal  Matters - 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.  In July 1998, the court granted motions
to dismiss, without prejudice, the claims against Calpine Gordonsville, Inc. and
Calpine  Auburndale,  Inc. In August 1998, Indeck filed an amended complaint and
the defendants filed motions to dismiss. A hearing on those motions is scheduled
for  January  1999.  The  Company  is unable to  predict  the  outcome  of these
proceedings.

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 September 30, 1998, TNP
has withheld  approximately $7.9 million related to transmission charges and has
continued to withhold  approximately  $450,000 per month thereafter.  In October
1997, CLC filed a petition for declaratory order with the Texas Public Utilities
Commission  ("Texas PUC") requesting a declaration that TNP's  withholding is in
error, which petition is currently pending.  Also, as of September 30, 1998, TNP
has  withheld  approximately  $7.7  million of  standby  power  charges  and has
continued to withhold approximately  $270,000 per month thereafter.  In addition
to the Texas PUC  petition,  CLC has  filed an action in Texas  courts  alleging
TNP's  breach of the power  sales  agreement  and is  seeking in excess of $15.0
million in damages.  A trial date is scheduled for January 1999.  The Company is
unable to predict the outcome of either of these proceedings.

An action was filed against Lockport Energy Associates, L.P. ("LEA") and the New
York  Public  Service  Commission  ("NYPSC")  in August  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 NYPSC and
the Federal Energy  Regulatory  Commission (the "FERC") to modify contract rates
to be  paid  to the  Lockport  Power  Plant.  In  October  1997,  NYPSC  filed a
cross-claim  alleging that the FERC violated Public Utility Regulatory  Policies
Act of 1978 as amended,

("PURPA") and the Federal Power Act by failing to reform the NYSEG contract that
was  previously  approved  by the NYPSC.  Although  it is unable to predict  the
outcome of this case, in any event, 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.

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  effect  on the  Company's  financial
position or results of  operations,  although no assurance  can be given in this
regard.

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.  At September 30, 1998,
the Company had  interests in 26 power plants and steam fields in six states and
Mexico, having an aggregate capacity of 3,097 megawatts.

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 $5.0 million.  Additionally,
on March 31,  1998 the  Company  repaid all  outstanding  project  debt of $38.2
million related to the Bethpage Power Plant.

On March 31, 1998,  the Company  completed the  acquisition of the remaining 50%
interest  in TCC,  which is the owner of the Texas  City and  Clear  Lake  Power
Plants.  The Company paid $52.8 million in cash and must make certain contingent
purchase payments that will approximate 2.2% of project revenue beginning in the
year 2000, increasing to 2.9% in 2002. As part of this acquisition,  the Company
owns  a 7.5%  interest  in the  Bayonne  Power  Plant,  a 165  megawatt  natural
gas-fired  cogeneration  power plant  located in Bayonne,  NJ. In addition,  the
Company paid $105.3 million to restructure certain gas contracts related to this
acquisition.

On July 13,  1998,  the Company  signed a letter of intent to enter into a joint
venture to develop, own and operate approximately 2,000 megawatts of new natural
gas-fired  power  plants in  northern  California,  to  primarily  serve the San
Francisco  Bay Area.  The  natural  gas-fired  plants are to be  constructed  by
Bechtel and  operated by the  Company.  The Company  intends for its first plant
developed  under the joint venture to be an 800 megawatt unit located at the Dow
Chemical facility in Pittsburg, CA.

On July 17, 1998, the Company completed the purchase of a 72 megawatt geothermal
power plant located in Sonoma County,  CA from the Sacramento  Municipal Utility
District  ("SMUD") for $13.0  million.  The Company is the owner and operator of
the  geothermal  steam fields that  provide  steam to this  facility.  Under the
agreement,  the Company paid SMUD $10.6 million at closing, and agreed to pay an
additional  $2.4  million  over the  next  two  years.  In  connection  with the
acquisition,  SMUD agreed to purchase 50 megawatts of electricity from the plant
at current  market  prices plus a  renewable  power  premium  through  2001.  In
addition,  SMUD has the option to purchase 10 megawatts of peak power production
through 2005. The Company will market the excess electricity into the California
power market.

On July 21, 1998, the Company completed the acquisition of a 70 megawatt natural
gas-fired power plant from The Dow Chemical  Company  ("Dow") for  approximately
$12.7  million.  The power  plant is located at Dow's  Pittsburg,  CA.

                                       15


chemical  facility.  The Company will sell up to 18 megawatts of  electricity to
Dow under a ten-year power sales agreement, with the balance sold to Pacific Gas
& Electric  Company under an existing power sales  agreement.  In addition,  the
Company will sell approximately 200,000 lbs./hr of steam to Dow and to USS-POSCO
Industries' nearby steel mill.

On August 28, 1998, the Company  entered into a sales and leaseback  transaction
for certain plant and  equipment of its  Greenleaf  1&2 Power  Plants,  two 49.5
megawatt gas-fired cogeneration facilities located in Sutter County,  California
for a net book value of $108.6  million.  Under the terms of the agreement,  the
Company received  approximately  $559,000 for the sale of all its rights,  title
and interest in the stock of Calpine Greenleaf Corporation,  and transferred all
non-recourse  project  financing of $71.6  million and  deferred  taxes of $39.8
million.  Annual rent payments under the operating lease agreements for 1998 are
approximately  $4.9  million  with  future  rent  payments  from  1999  to  2004
continuing  at $9.0 million per year and $71.6 million  thereafter  through June
2014.  A gain of $2.8  million was  recorded  on the balance  sheet and is being
amortized and recognized over the term of the lease of June 2014.  Additionally,
the Company has an early purchase option expiring September 30, 2003 to exercise
the end of term purchase.

On September 28, 1998,  the Company  entered into a partnership  agreement  with
Energy  Management,  Inc.  ("EMI")  to acquire an  ownership  interest  in a 265
megawatt gas-fired plant under  construction in Tiverton,  Rhode Island. EMI and
the Company will be co-general partners for this project, with EMI acting as the
Managing  General  Partner.  The Company invested $40.0 million of equity in the
merchant power plant, which is scheduled to go into commercial  operation in May
2000.  The Company will  receive up to 63% of all cash and income  distributions
from the  Tiverton  project  until it receives a 10.5%  pre-tax  rate of return.
Thereafter, the Company will receive 50% of all distributions.

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

Results of Operations

Three and Nine Months Ended September 30, 1998 Compared to Three and Nine Months
Ended September 30, 1997

Revenue -- Total revenue was $186.2 million and $382.9 million for the three and
nine months ended  September 30, 1998,  as compared to $92.9 and $199.9  million
for the comparable periods in 1997.

     Electricity  and  steam  sales  revenue  increased  112% and 98% to  $168.6
million and $347.4  million in 1998 compared to $79.4 million and $175.8 million
for the comparable three and nine months ended September 30, 1997. These results
were achieved from an existing portfolio of projects  performing as expected and
due to  acquisitions  completed  earlier in the year.  The newly  acquired power
plants at Texas City,  Clear Lake,  Pittsburg  and Bethpage  accounted for $82.7
million  or  49%  of  the   Company's   third  quarter   electricity   revenues.
Additionally, the Company benefited from the startup of its first merchant power
plant in Pasadena,  Texas which became operational in July 1998. The increase in
revenues at the Texas City,  Clear Lake and  Pasadena  Power  Plants  during the
third quarter were attributable to higher energy prices which were the result of
a shortage of capacity to support  higher energy demands caused by unusually hot
weather in Texas during the period.  The increase in electricity and steam sales
revenues for the nine months ended  September 30, 1998 was due to $163.0 million
of electricity  revenues at the Texas City,  Clear Lake,  Bethpage and Pittsburg
Power Plants which were  acquired  during the first nine months ended  September
30, 1998. In addition the Company  benefited from the Pasadena Power Plant which
became operational ahead of schedule allowing the Company to take full advantage
of this peak market  prior to the  initiation  of its steam and  electric  sales
contract with Phillips  Petroleum  which  commenced in  mid-September.  Capacity
revenues  increased  $67.4 million for the nine months ended  September 30, 1998
primarily  due to the  acquisition  of the Texas City,  Clear Lake and Pittsburg
Power Plants.

     Service  contract  revenue  increased to $7.8 million and $16.4 million for
the three and nine months ended  September 30, 1998, as compared to $3.3 million
and $6.9 million for the comparable  periods in 1997. The $4.5 million  increase
in  service   contract   revenue  for  the  three  months  ended  was  primarily
attributable  to a $2.7 million  increase from Calpine Power  Services which was
selling the energy  generated  by the  Pasadena  Power Plant on the open market,
fuel  management  fees and related  third party gas sales.  The  Company's  $9.5
million  increase for the nine months ended  September  30, 1998 was due to $2.7
million for Calpine Power Services increased marketing activity for the Pasadena
Power Plant, $ 2.8 million for fuel management  fees, and $3.8 million for third
party excess gas sales.

                                       17


     Income from unconsolidated  investments in power projects increased 197% to
$9.8  million for the three months ended  September  30, 1998 which  compared to
$3.3  million  for the same  period in 1997.  The  increase  of $6.5  million is
primarily  attributable  to equity income from the Company's  investments in the
Lockport and Bayonne Power Plants. For the nine months ended September 30, 1998,
the Company  recorded equity income of $16.6 million as compared to $7.5 million
in 1997.  This growth was primarily due to equity income from the Texas City and
Clear Lake Power Plants.  The Company initially acquired a 50% interest in these
plants in June 1997 and subsequently  purchased the remaining  interest in March
1998.  The  investment  in the Texas City,  Clear Lake and Bayonne  Power Plants
contributed  $4.3 million for nine months in 1998 as compared to $1.8 million in
1997.  Additionally,  the  Company's  investment  in the  Lockport  Power  Plant
contributed  $6.0 million of equity income during the first nine months of 1998.
These  increases  for the nine months ended  September  30, 1998 were  partially
offset by a $1.4 million decrease in equity income from the Sumas Power Plant.

Interest income on loans to power projects  decreased to $0 and $2.6 million for
the three  months and nine months ended  September  30, 1998 as compared to $6.8
million and $9.8  million for the same  periods in 1997.  These  decreases  were
related  to  interest  income  recognized  in 1997 on (i) loans  assumed  by the
Company for TCC in connection  with the initial 50%  acquisition  (see Note 9 of
the  Notes  to the  Condensed  Consolidated  Financial  Statements),  which  was
subsequently  repaid to the Company when the  remaining  50% interest in TCC was
acquired on March 31, 1998, and (ii) loans made to the sole shareholder of Sumas
Energy Inc., the Company's partner in Sumas, which were repaid to the Company on
December 31, 1997.

Cost of revenue - Cost of revenue  increased 172% and 128% to $117.1 million and
$253.2  million  compared to $43.1 million and $110.9 million for the comparable
three and nine months in 1997.  The increase of $74.0 and $142.3 million for the
three and nine months ended  September  30, 1998 was primarily  attributable  to
increased plant  operating,  fuel and  depreciation  expenses as a result of the
acquisition  of the  interest  in the  Texas  City,  Clear  Lake,  Bethpage  and
Pittsburg   Power  Plants  and  the  startup  of  the   Pasadena   Power  Plant.
Additionally, there was a $5.5 million increase in service contract expenses for
the nine months ended  September  30, 1998, of which $3.6 million was related to
the Texas City and Clear Lake Power Plants' operating and maintenance  contracts
and a $1.9 million increase for fuel management contracts.

Project development  expenses - Project development  expenses decreased to $1.7
million and $4.8 million for the three and nine months ended  September 30, 1998
compared to $1.8  million and $5.7 million for the  comparable  periods in 1997.
The decrease is due primarily to certain  one-time  charges  incurred during the
first three months of 1997 related to project development activities.

General  and  administrative  expenses  - General  and  administrative  expenses
increased to $7.4 million and $18.4  million for the three and nine months ended
September 30, 1998 compared to $4.6 million and $13.2 million for the comparable
periods in 1997.  The  increase  was  attributable  to the  continued  growth in
personnel  and overhead  costs  necessary  to support the overall  growth in the
Company's operations.

Interest  expense - Interest  expense  increased to $24.3  million for the three
months ended  September 30, 1998,  compared to $17.2 million for the same period
in 1997.  The increase was primarily  attributable  to interest  expense of $7.6
million  related to the 7-7/8%  Senior  Notes Due 2008  issued in March and July
1998.  This increase was partially  offset by $492,000 for the reduction of debt
at Calpine  Greenleaf.  Interest expense increased to $65.1 million for the nine
months ended  September 30, 1998,  compared to $43.4 million for the same period
in 1997.  The increase was  attributable  to interest  expense of $14.3  million
related to the 8-3/4% Senior Notes Due 2007 issued July and September  1997, and
$13.6 million related to the 7-7/8 % Senior Notes Due 2008. These increases were
partially offset by $1.4 million of interest  capitalized on the development and
construction  of power  projects,  $3.3  million for the  reduction  for debt at
Calpine Geysers  Company,  $869,000 for the reduction of debt at Calpine Finance
Company, and $581,000 for the reduction of debt at Calpine Greenleaf.

Interest income - Interest income increased to $3.7 million for the three months
ended September 30, 1998,  compared to $3.3 million for the same period in 1997.
The increase was the result of higher cash and cash  equivalent  balances during
the third  quarter of 1998.  Interest  income  decreased to $9.4 million for the
nine months ended  September  30, 1998,  compared to $10.2  million for the same
period in 1997.  This decrease was the result of lower cash and cash  equivalent
balances.

Other expense (income),  net - Other expense (income) net,  decreased to $72,000
and ($834,000)  for the three and nine months ended  September 30, 1998 compared
to ($616,000)  and ($1.6 million) for the same periods in 1997. The decrease was
primarily due to lower royalty income at the Company's geothermal facilities.

                                       18


Provision  for income taxes - The  effective  income tax rate was  approximately
37.3% for the nine months ended  September  30, 1998.  The  reductions  from the
statutory  rate were  primarily due to depletion in excess of tax basis benefits
at the Company's  geothermal  facilities,  and a decrease in the  California tax
liability due to the Company's expansion into states other than California.

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  flows  activities  for  the  periods   indicated   (dollars  in
thousands):

Operating  activities  for the nine months  ended Sept 30, 1998  provided  $72.9
million,   consisting  of  approximately   $53.5  million  of  depreciation  and
amortization,  $31.6 million of net income,  $17.7 million of distributions from
unconsolidated  investments  in power  projects,  and $14.1  million of deferred
income  taxes.  This was offset by $16.2  million of income from  unconsolidated
investments,  $16.5  million net increase in operating  assets and $11.3 million
net decrease in operating liabilities.

Investing  activities  for the nine months ended  September 30, 1998 used $269.3
million,  primarily due to $155.6  million for the  acquisition of the remaining
50% interest in the Texas City and Clear Lake Power Plants, $4.5 million for the
acquisition  of the  remaining 55% interest in the Bethpage  Power Plant,  $27.2
million of capital  expenditures  related to the  construction  of the  Pasadena
Power Plant,  $13.1 million for the  acquisition  of the Pittsburg  Power Plant,
$11.9 million for the  acquisition of the Sonoma Power Plant,  $40.0 million for
the  acquisition  of the Tiverton  Power Plant,  $12.5  million of other capital
expenditures,  $19.6 million of  capitalized  project  development  costs,  $4.5
million of interest capitalized on construction projects,  offset by the receipt
of $12.8 million of loan  payments,  $833,000 of  investments  in power projects
specifically  Calpine  Eastern,  and $6.0 million of  maturities  of  collateral
securities in connection with the King City Power Plant.

     Financing  activities for the nine months ended September 30, 1998 provided
$248.5  million  of cash  consisting  of $52.1  million  of  borrowings  for the
construction  of the Pasadena 1 Power  Plant,  $4.3  million of  borrowings  for
contingent  consideration in connection with the acquisition of the Gilroy Power
Plant,  $395.2  million of net proceeds  from  additional  financings,  and $1.1
million for the issuance of common stock,  partially offset by $195.9 million in
repayment of  non-recourse  project  financing,  $8.3 million of  repurchase  of
Senior Notes Due 2006 which includes a premium paid and accrued  interest to the
date of repurchase.

At September 30, 1998, cash and cash equivalents were $100.6 million and working
capital was $147.1  million.  For the nine months ended September 30, 1998, cash
and cash equivalents increased by $52.1 million and working capital increased by
$159.1 million as compared to December 31, 1997.

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 cash from operations,  borrowings under its credit facilities,
other lines of credit, non-recourse project financing or long-term debt, and the
sale of equity.

                                       19


Management continues to evaluate current and forecasted cash flow as a basis for
financing operating requirements and capital expenditures.  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  for the  next  twelve
months.  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.

On March 31, 1998,  the Company  completed  the Rule 144A offering of its $300.0
million Senior Notes Due 2008 which mature on April 1, 2008 and bear an interest
payable  semi-annually on April 1 and October 1 of each year commencing  October
1,  1998  (See  Note  11  to  the  Notes  to  Condensed  Consolidated  Financial
Statements).  Subsequent  to  this  offering,  on July  24,  1998,  the  Company
completed the Rule 144A offering of an additional  $100.0  million  Senior Notes
Due 2008.  After deducting  discounts to initial  purchasers and expenses of the
offerings,  the net  proceeds  from the sale of the  Senior  Notes Due 2008 were
approximately  $98.8  million.  (See  Note  11 to the  Notes  to  the  Condensed
Consolidated Financial Statements).

At  September  30,  1998,  the Company  had a $100.0  million  revolving  credit
facility  available with a consortium of commercial  lending  institutions.  The
Company had no  borrowings  and $26.7  million of letters of credit  outstanding
under  the  credit  facility  (See  Note 12 of Notes to  Condensed  Consolidated
Financial  Statements).  The 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.

At September 30, 1998, the Company also 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 $171.8 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 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. At September 30, 1998, $275.0 million of
these senior notes were outstanding.

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 September 30, 1998, the Company had no borrowings under this working
capital  line and $74,000 of letters of credit  outstanding.  Borrowings  are at
prime plus 1%.

Outlook

Expand diversify  domestic  portfolio of power projects - In pursuing its growth
strategy,  the Company intends to focus on  opportunities  for the  acquisition,
development and operation of power generation facilities.  The 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 gas
cogeneration facilities and steam fields. As a result of these transactions, the
Company has significantly  increased its aggregate power generation capacity and
substantially diversified its fuel mix.

Development  of new power plants - The Company is also pursuing the  development
of   efficient,   low-cost   power  plants  that  seek  to  take   advantage  of
inefficiencies  in the  electric  market.  The Company  intends to sell all or a
portion of the power  generated by such new plants into the  competitive  market
through a portfolio of short-, medium- and long-term power sales agreements. The
Company currently plans to develop additional low-cost,  gas-fired facilities in
California, Texas, New England and other power markets.

Impact of  Avoided  Cost  Pricing - The  Company  receives  from  Pacific  Gas &
Electric  ("PG&E")  a fixed  price of 13.83  cents for each  unit of  electrical
energy  according to schedules set forth in the long-term power sales agreements
for the Bear Canyon and West Ford Flat Power  Plants.  The fixed  price  periods
under these power sales  agreements  expired 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 will adjust from 

                                       20


the interim  short-run avoided cost ("SRAC") to the energy clearing price of the
independent  power exchange,  once it is deemed fully  implemented.  The average
prices per  kilowatt for SRAC for the year 1997 and for the first nine months of
1998 were 2.94 cents and 2.61  cents,  respectively.  Due to  seasonality,  such
average energy prices may not be indicative of future energy prices.  During the
first nine  months of 1998,  the Bear  Canyon  and West Ford Flat  Power  Plants
generated  approximately  304,384,000  kilowatt  hours of electrical  energy for
sale.  The  Company  expects  decreased  royalty  expenses  and  operating  cost
reductions  can  mitigate  the  forecasted  decline in energy  revenues at these
facilities,  although  there can be no  assurances  in this regard.  The Company
expects to continue  its strategy of replacing  decreased  revenues  through its
acquisition and development program.

Deregulation within the Power Generation Industry - Many states are implementing
or considering  regulatory  initiatives  designed to increase competition in the
domestic power  generation  industry.  In December  1995, the California  Public
Utilities   Commission  ("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 and  deregulation
commenced on 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 believes that the  restructuring  will not have a material effect on
any of its power sales agreements and,  accordingly,  believes that its existing
business and results of operations  will not be materially  adversely  affected,
although there can be no assurance in this regard.

Impact  of  Recent  Accounting  Pronouncements  - In April  1998,  the  American
Institute of Certified Public Accountants ("AICPA") issued Statement of Position
("SOP") No.  98-5,  "Reporting  on the Costs of Start-Up  Activities,"  which is
effective for financial statements for fiscal years beginning after December 15,
1998. For purposes of this SOP, start-up activities are defined broadly as those
one-time activities related to opening a new facility,  conducting business in a
new territory,  conducting business with a new class of customer or beneficiary,
initiating  a new  process  in an  existing  facility,  or  commencing  some new
operation.  Start-up  activities  include activities related to organizing a new
entity (commonly referred to as organization  costs).  Although earlier adoption
is encouraged, the Company has not yet quantified or determined the timing of or
method of the adoption.

In June 1998,  the  Financial  Accounting  Standards  Board issued  Statement of
Financial  Accounting  Standards  ("SFAS") No. 133,  "Accounting  for Derivative
Instruments and Hedging Activities".  The Statement  establishes  accounting and
reporting  standards,  requiring every derivative  instrument be recorded in the
balance  sheet as either an asset or liability  measured at its fair value.  The
Statement  requires  that changes in the  derivative's  fair value be recognized
currently in earnings unless specific hedge accounting criteria are met. Special
accounting  for  qualifying  hedges  allows a  derivative's  gains and losses to
offset related results on the hedged item in the income  statement,  and require
that a company formally  document,  designate,  and assess the  effectiveness of
transactions that receive hedge accounting.

SFAS No. 133 is effective for fiscal years  beginning  after June 15, 1999.  The
Statement must be applied to derivative  instruments  and to certain  derivative
instruments  embedded  in  hybrid  contracts  that  were  issued,  acquired,  or
substantively modified after December 31, 1997.

The Company  has not yet  analyzed  the impact of  adopting  SFAS No. 133 on the
financial  statements  and has not  determined  the  timing  of or method of the
adoption of SFAS No. 133.  However the Statement  could  increase  volatility in
earnings.

Year 2000  Compliance  - The "Year  2000  problem"  refers to the fact that some
computer hardware, software and embedded systems were designed to read and store
dates using only the last two digits of the year.

The  Company is  coordinating  its efforts to address the impact of Year 2000 on
the  Company's   business   through  a  Year  2000  Project  Team  comprised  of
representatives  from each  business  unit and the  Company's  Year 2000 Project
Office. The Year 2000 Project Office is charged with addressing  additional Year
2000 related issues  including,  but not limited to, business  continuation  and
other  contingency  planning.  The Year 2000  Project  Team meets  regularly  to
monitor the efforts of assigned staff and contractors to identify, remediate and
test the Company's technology.

     The Year 2000 Project Team is focusing on four separate technology domains:

     *     corporate applications, which include core business systems;

                                       21

   
     *     non-information technology, which includes all operating and 
            control systems;
     *    end-user  computing  systems (that is,  systems that are not,  
            considered  core business  systems but may
         contain date calculations); and
          business partner and vendor systems.

     Corporate  Applications  -  Corporate  applications  are those  major  core
systems, such as customer  information,  human resources and general ledger, for
which  the  Company's   Management   Information   Systems  department  has  the
responsibility.  The Company utilizes PeopleSoft for its major core systems. The
PeopleSoft  applications  utilized by the Company are in operation and have been
determined to be Year 2000 compliant.

     Non-Information  Technology/Embedded  Systems - Non-information  technology
includes   such  items  as  power   plant   operating   and   control   systems,
telecommunications  and facilities-based  equipment (e.g. telephones and two-way
radios) and other embedded  systems.  Each business unit is responsible  for the
inventory and remediation of its embedded systems.  In addition,  the Company is
working with the  Electric  Power  Research  Institute,  a  consortium  of power
companies, including investor-owned utilities, to coordinate vendor contacts and
product evaluation.  Because many embedded systems are similar across utilities,
this concentrated  effort should help to reduce total time expended in this area
and help to ensure that the Company's  efforts are  consistent  with the efforts
and practices of other power companies and utilities.

Inventory  of  non-information  technology/embedded  systems  was  completed  in
October 1998. The Company plans to complete remediation of non-compliant systems
by the second  quarter of 1999.  To date,  all  embedded  systems that have been
identified  by the Company can be  upgraded  or  modified  within the  Company's
current schedule.

Testing of  embedded  systems is complex  because  some of the  testing  must be
completed during power plant scheduled  maintenance outages. Much of the testing
will  be  accomplished  in  the  spring  of  1999  during  regularly   scheduled
maintenance  outage  periods.  At that time,  at least one typical  unit of each
critical type will be tested by the Company or in  cooperation  with other power
companies, and the requirement for further testing will be determined.

     End-User  Computing  Systems - Some of the  Company's  business  units have
developed systems, databases, spreadsheets, etc. that contain date calculations.
Compliance of  individual  workstations  is also included in this domain.  These
systems comprise a relatively  small percentage of the required  modification in
terms of both number and criticality.

     The Company's  end-user  computing  systems are being  inventoried  by each
business  unit and evaluated  and  remediated  by the  Company's MIS staff.  The
Company expects to complete  remediation  and testing of the end-user  computing
systems by mid-1999.

     Business  Partner  and Vendor  Systems - The  Company  has  contracts  with
business  partners and vendors who provide products and services to the Company.
The  Company is  vigorously  seeking to obtain Year 2000  assurances  from these
third parties. Year 2000 Project Team and appropriate business units are jointly
undertaking this effort.

     Contingency Planning Contingency and business  continuation planning are in
various  stages of  development  for critical  and  high-priority  systems.  The
Company's  existing  disaster  response  plan and  other  contingency  plans are
scheduled  to be  evaluated  and  will be  adopted  for use in case of any  Year
2000-related  disruption.  The  Company  expects  to  complete  its  contingency
planning by October 1999.

     Costs - The costs of expected  modifications  is currently  estimated to be
approximately  $1.7 million  which will be charged to expense as incurred.  From
January 1, 1998 through September 30, 1998, $81,000 has been charged to expense.
Approximately  12% of the estimated total cost will be incurred in 1998, and the
remainder  will be incurred in 1999 and 2000.  These costs have been and will be
funded  through  operating cash flow.  These  estimates may change as additional
evaluations are completed and remediation and testing progress.

     Risks - The Company  currently  expects to complete  its Year 2000  efforts
with respect to critical  systems by mid-1999.  This  schedule and the Company's
cost estimates may be affected by, among other things,  the availability of Year
2000  personnel,  the  readiness  of third  parties,  the timing for testing the
Company's  embedded  systems,  the  availability of vendor resources to complete
embedded system  assessments  and produce  required  component  

                                       22


upgrades and the Company's ability to implement appropriate contingency plans.

The Company  produces  revenues by selling power it produces to  customers.  The
Company depends on transmission and  distribution  facilities that are owned and
operated  by  investor-owned   utilities  to  deliver  power  to  the  Company's
customers.  If either the Company's  customers or the providers of  transmission
and distribution  facilities experience  significant  disruptions as a result of
the Year 2000 problem,  the  Company's  ability to sell and deliver power may be
hindered, which could result in a loss of revenue.

The cost or  consequences of a materially  incomplete or untimely  resolution of
the Year 2000  problem  could  adversely  affect  future  operations,  financial
results or the financial condition of the Company.

The  forward-looking  statements  discussed  in this outlook  section  involve a
number of risks and uncertainties.  Other risks and uncertainties  include,  but
are not limited to, the general  economy,  regulatory  conditions,  the changing
environment of the power generation industry,  pricing, the effects of legal and
administrative cases and proceedings,  and such other risks and uncertainties as
may be detailed from time to time in the Company's SEC reports and filings.

PART II.    OTHER INFORMATION

ITEM 1.  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  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.  In July 1998, the court granted motions to dismiss,
without  prejudice,  the claims against Calpine  Gordonsville,  Inc. and Calpine
Auburndale,  Inc. In August  1998,  Indeck  filed an amended  complaint  and the
defendants filed motions to dismiss. A hearing on those motions is scheduled for
January 1999. The Company is unable to predict the outcome of these proceedings.

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 September 30, 1998, TNP
has withheld  approximately $7.9 million related to transmission charges and has
continued to withhold  approximately  $450,000 per month thereafter.  In October
1997, CLC filed a petition for declaratory order with the Texas Public Utilities
Commission  ("Texas PUC") requesting a declaration that TNP's  withholding is in
error, which petition is currently pending.  Also, as of September 30, 1998, TNP
has  withheld  approximately  $7.7  million of  standby  power  charges  and has
continued to withhold approximately  $270,000 per month thereafter.  In addition
to the Texas PUC  petition,  CLC has  filed an action in Texas  courts  alleging
TNP's  breach of the power  sales  agreement  and is  seeking in excess of $15.0
million in damages.  A trial date is scheduled for January 1999.  The Company is
unable to predict the outcome of either of these proceedings.

An action was filed against Lockport Energy Associates, L.P. ("LEA") and the New
York  Public  Service  Commission  ("NYPSC")  in August  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 NYPSC and
the Federal Energy  Regulatory  Commission (the "FERC") to modify contract rates
to be  paid  to the  Lockport  Power  Plant.  In  October  1997,  NYPSC  filed a
cross-claim  alleging that the FERC violated  PURPA and the Federal Power Act by
failing to reform the NYSEG contract that was previously  approved by the NYPSC.
Although  it is unable to predict the  outcome of this case,  in any event,  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.

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  effect  on the  Company's  financial

                                       23


position or results of  operations,  although no assurance  can be given in this
regard.
