1.       Organization and Operation of the Company

Calpine Corporation, 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 principally
in the United  States.  The  Company has  ownership  interests  in and  operates
gas-fired cogeneration facilities,  geothermal steam fields and geothermal power
generation  facilities  in northern  California,  Washington,  Texas and various
locations  on the  East  Coast.  Each  of  the  generation  facilities  produces
electricity  which is marketed to  utilities  and other third party  purchasers.
Thermal energy  produced by the gas-fired  cogeneration  facilities is primarily
sold to industrial users.

2.       Summary of Significant Accounting Policies

Basis of Interim Presentation -- The accompanying interim 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
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, 1998. The results for interim  periods
are not necessarily indicative of the results for the entire year.

Stock Split -- On September  20, 1999,  the Board of Directors  authorized a two
for one stock split of the Company's common stock, to be effected in the form of
a stock  dividend,  payable to  stockholders of record as of September 23, 1999.
New shares were  distributed  on October 7, 1999.  All  references  to number of
shares,  except  shares  authorized,   and  to  per  share  information  in  the
consolidated  financial statements have been adjusted to reflect the two for one
stock split on a  retroactive  basis.  Par value remains at $.001 per share as a
result of transferring  $27,000 to common stock from additional paid-in capital,
representing the aggregate par value of the shares issued under the stock split.

Capitalized  interest -- The Company capitalizes interest on projects during the
construction  period. For the nine months ended September 30, 1999 and 1998, the
Company capitalized $29.3 million and $6.9 million, respectively, of interest in
connection with the 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 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 debt.

New  Accounting  Pronouncements  --  In  June  1999,  the  Financial  Accounting
Standards Board issued Statement of Financial  Accounting Standards ("SFAS") No.
137, "Accounting for Derivative Instruments and Hedging Activities - Deferral of
the Effective Date of SFAS No. 133". The Statement  amends SFAS No. 133 to defer
its effective date to all fiscal  quarters of all fiscal years  beginning  after
June 15, 2000.  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 the
volatility of the Company's earnings.

Reclassifications  --  Prior  period  amounts  in  the  consolidated   financial
statements  have  been  reclassified  where  necessary  to  conform  to the 1999
presentation.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)
                               September 30, 1999

(1)  On  December  31,  1998,  the   Partnership   agreement   governing   Sumas
     Cogeneration Company, L.P. ("Sumas") was amended changing the distributions
     schedule  for the  Company  from the  previously  amended  agreement  dated
     September 30, 1997. The newly amended  agreement  reflects the earnings the
     Company  was  entitled  to under that  agreement  from a  variable  payment
     schedule  to  a  fixed  payment  schedule.   On  September  30,  1997,  the
     partnership agreement 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)  The Company  acquired an additional  50% interest in the Aidlin Power Plant
     on August 31, 1999. As such, the Company has consolidated the operations of
     the Aidlin Power Plant.

5.       Common Stock and Senior Notes Offering

The following share  information  reflects the two for one stock split effective
on October 7, 1999. On March 26, 1999, the Company  completed a public  offering
of 12,000,000  shares of its common stock at $15.50 per share.  The net proceeds
from this public offering were approximately  $177.9 million.  Additionally,  in
April 1999, the Company sold an additional  1,800,000  shares of common stock at
$15.50 per share  pursuant to the exercise of the  underwriters'  over-allotment
option for net proceeds of approximately $26.7 million.

On March 29, 1999, the Company  completed a public offering of $250.0 million of
its 7-5/8% Senior Notes Due 2006 ("Senior Notes Due 2006") and $350.0 million of
its 7-3/4% Senior Notes Due 2009 ("Senior Notes Due 2009"). The Senior Notes Due
2006 bear  interest at 7-5/8% per year,  payable  semi-annually  on April 15 and
October  15 and  mature on April 15,  2006.  The  Senior  Notes Due 2006 are not
redeemable prior to maturity.  The Senior Notes Due 2009 bear interest at 7-3/4%
per year,  payable  semi-annually on April 15 and October 15 and mature on April
15, 2009. The Senior Notes Due 2009 are not redeemable prior to maturity.  After
deducting underwriting discounts and expenses of the offering, the aggregate net
proceeds from the sale of the Senior Notes were approximately $587.5 million.

The net proceeds from the sale of the common  stock,  the Senior Notes Due 2006,
and the  Senior  Notes Due 2009 were used as  follows:  (i)  $120.6  million  to
refinance indebtedness relating to the Gilroy Power Plant, (ii) $77.6 million to
repay  indebtedness  under a bridge  facility  provided by Credit  Suisse  First
Boston to finance a portion of the  purchase  price to acquire the steam  fields
that  service the Sonoma  County  power  plants,  (iii)  $50.0  million to repay
outstanding  borrowings under our revolving credit facility,  (iv) $25.0 million
to complete  the  expansion  of the Clear Lake Power  Plant,  (v)  approximately
$400.0  million to finance a portion of power  generation  facilities  currently
under construction and the projects  currently under  development,  and (vi) the
remaining $118.9 million was used for general  corporate  purposes.  Transaction
costs incurred in connection  with the Senior Notes offerings were recorded as a
deferred charge and are amortized over the respective  lives of the Senior Notes
Due 2006 and the Senior Notes Due 2009 using the effective interest rate method.

6.       Acquisitions

Unocal Transaction

On March 19, 1999, the Company completed the acquisition of Unocal Corporation's
Geysers geothermal steam fields in northern California for approximately  $102.1
million.  The steam  fields fuel the  Company's 12 Sonoma  County power  plants,
totaling  544  megawatts of capacity.  The Company  purchased  these plants from
Pacific Gas & Electric Company ("PG&E") on May 7, 1999.

PG&E Transactions

On May 7, 1999, the Company completed the acquisitions of 12 Sonoma County and 2
Lake County  power  plants  located at The Geysers,  California  from PG&E.  The
approximate  purchase price was $212.8 million.  The acquisitions  were financed
with a 24-year  operating  lease (see Note 10). The Company's  geothermal  steam
fields fuel the facilities,  which have a combined capacity of approximately 700
megawatts of electricity.  All of the electricity  generated from the facilities
is sold into the California energy market,  with the exception of megawatts sold
under an  agreement  entered  into on April 29,  1999 with  Commonwealth  Energy
Corporation  as follows:  75 megawatts in 1999,  100 megawatts in 2000,  and 125
megawatts in 2001 and through June 2002.

7.       Construction Financing

On January 4, 1999, the Company entered into a Credit  Agreement with ING (U.S.)
Capital  LLC  ("ING") to provide up to $265.0  million of  non-recourse  project
financing  for  the  construction  of the  Pasadena  facility  expansion.  As of
September 30, 1999,  $115.2 million was outstanding as a construction loan under
the agreement.  The  outstanding  loan bears interest at ING's base rate plus an
applicable  margin  or at  LIBOR  plus  an  applicable  margin  and  is  payable
quarterly.  The  construction  loan will convert to a term loan once the project
has completed construction.  The construction loan will mature on or before July
1,  2000,  but is  subject  to an  extension  to  October  1,  2000 if there are
sufficient  construction funds available.  The term loan will be available for a
period not to exceed five years from the  construction  loan  maturity  date. In
connection with the Credit  Agreement,  the Company entered into a $10.0 million
letter of credit  facility.  At  September  30,  1999,  there were no letters of
credit outstanding under the facility.

8.       Revolving Credit Facility and Line of Credit

The Company  maintains a credit facility of $100.0  million,  which is available
through a consortium of commercial lending  institutions led by The Bank of Nova
Scotia as agent.  A maximum  of $50.0  million  of the  credit  facility  may be
allocated  to letters of credit.  At  September  30,  1999,  the  Company had no
borrowings and $26.0 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 LIBOR plus an applicable margin.  Interest is paid on
the  last day of each  interest  period  for such  loans.  The  credit  facility
specifies that the Company  maintain certain  covenants,  with which the Company
was in  compliance  as of September  30, 1999.  Commitment  fees related to this
credit facility are charged based on 0.375% of committed unused funds.

The Company had a $12.0 million  letter of credit  outstanding  with The Bank of
Nova Scotia to secure performance of the Clear Lake Power Plant.

The Company  recognized  an  extraordinary  charge of $1.2  million or $0.03 per
share  (net of tax  benefit  of  $793,000)  in April of 1999,  representing  the
write-off of deferred financing costs related to non-recourse  project financing
for the Gilroy Power Plant.  The  financing  agreement  was  terminated  and the
outstanding balance of $120.6 million was repaid in April of 1999. 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.  For the
nine  months  ended   September  30,  1998,   the  Company  has   recognized  an
extraordinary  charge of  $641,000  or $0.01 per share  (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 720,800 and 98,000 shares of the
Company's common stock during the nine months ended September 30, 1999 and 1998,
respectively, were not included in the computation of diluted shares outstanding
because such inclusion would be anti-dilutive.

10.      Commitments and Contingencies

Production  Royalties  and Leases -- The  Company  is  committed  under  several
geothermal  leases  and  right-of-way,  easement  and  surface  agreements.  The
geothermal  leases generally  provide for royalties based on production  revenue
with reductions for property taxes paid. The right-of-way,  easement and surface
agreements are based on flat rates and are not material. Certain properties also
have net profits and overriding  royalty  interests  ranging from  approximately
1.45% to 28%, which are in addition to the land

                               September 30, 1999

royalties.  Most lease  agreements  contain clauses  providing for minimum lease
payments to lessors if  production  temporarily  ceases or if  production  falls
below a specified level.

The  Company  leases its  corporate  offices and  regional  offices in San Jose,
California,  Boston, Massachusetts,  Houston, Texas and Pleasanton,  California,
under  noncancellable  operating  leases expiring  through 2002.  Future minimum
lease  payments  under these leases for the remainder of 1999 are  approximately
$500,000.

Facilities  Operating  and Land  Leases - The  Company  entered  into  long-term
operating  leases  in June  1995,  May  1996,  August  1998 and May 1999 for its
Watsonville,  King City, Greenleaf,  Sonoma and Lake County power plants and the
land lease for the Pasadena  Power Plant.  Future  minimum lease  payments under
these leases for the remainder of 1999 are approximately $10.6 million.

In May 1999,  the Company  entered  into a sale and  leaseback  transaction  for
certain plant and equipment  located at The Geysers,  California  for a net book
value of $231.8 million.  Included in the transaction  were the 12 Sonoma County
and 2 Lake County power plants  purchased from PG&E on May 7, 1999 (see Note 6),
as well as the Sonoma Power Plant acquired from the Sacramento Municipal Utility
District in 1998.  Under the terms of the agreement,  the Company received $18.5
million and recorded a deferred gain of $15.2 million on the balance sheet.  The
deferred gain is being amortized over the term of the lease through May 2022.

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

Capital  expenditures  -- At September 30, 1999,  the Company was under contract
with Siemens  Westinghouse Power Corporation for a total of $1.8 billion for the
purchase of 50 turbines.  Approximate payments related to these turbines for the
nine months ended September 30, 1999 was $487.4 million.

Litigation

On September 30, 1997, a lawsuit was filed by Indeck North  American  Power Fund
("Indeck") in the Circuit Court of Cook County, Illinois against Norweb plc. and
certain other parties,  including the Company. Some of Indeck's claims relate to
Calpine  Gordonsville,  Inc.'s  acquisition  of a 50%  interest in  Gordonsville
Energy  L.P.  from  Northern  Hydro  Limited  and  Calpine  Auburndale,   Inc.'s
acquisition  of a 50%  interest  in  Auburndale  Power  Plant  Partners  Limited
Partnership  from Norweb Power  Services  (No. 1) Limited.  Indeck  claimed that
Calpine Gordonsville,  Inc., Calpine Auburndale, Inc. and the Company tortuously
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 April 1999, the court granted Calpine Gordonsville
and Calpine Auburndale's motions to dismiss with prejudice, a decision which has
been  appealed by Indeck.  The Company is unable to predict the outcome of these
proceedings.

An action was filed against  Lockport Energy  Associates,  L.P. 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  ("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 the 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 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 adverse

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

11.      Subsequent Events

On October 1, 1999, the Company  completed the  acquisition  of Sheridan  Energy
Inc.  ("Sheridan  Energy"),  a natural gas exploration  and production  company,
through a $41.0 million cash tender offer. The Company purchased the outstanding
shares of Sheridan  Energy's  common stock for $5.50 per share and assumed $64.5
million of outstanding debt. In addition,  the Company redeemed $11.5 million of
outstanding  preferred stock of Sheridan Energy.  Sheridan  Energy's oil and gas
properties,  including 148 billion cubic feet equivalent of proven reserves, are
located in Northern  California  and the Gulf Coast region.  On January 4, 1999,
the Company  acquired a 20% interest in Sheridan  California  Energy,  Inc. from
Sheridan Energy. As a result of the two aforementioned acquisitions, the Company
now owns all of the assets of Sheridan Energy.

On November 2, 1999, the Company completed a public offering of 7,200,000 shares
of its common  stock at $46.31  per share.  The net  proceeds  from this  public
offering  were  approximately  $320.3  million.  The Company sold an  additional
1,080,000 shares of common stock at $46.31 per share pursuant to the exercise of
the underwriters'  over-allotment option for net proceeds of approximately $48.2
million.

Concurrently  with the public  offering  dated  November 2, 1999,  the  Company,
through its subsidiary Calpine Capital Trust, a statutory business trust created
under Delaware law, completed an offering of 4,800,000  Remarketable Term Income
Deferrable Equity Securities ("trust preferred securities") at a value of $50.00
per share. The net proceeds from the offering were approximately $233.2 million.
The Company sold an additional 720,000 trust preferred  securities at a value of
$50.00 per share  pursuant to the exercise of the  underwriters'  over-allotment
option for net proceeds of  approximately  $35.0 million.  The net proceeds from
the offering  were used by the  Company's  subsidiary  to invest in  convertible
subordinated debentures of the Company, which represent substantially all of the
subsidiary's  assets.  The  Company  has  guaranteed  all  of  the  subsidiary's
obligations under the trust preferred securities. The trust preferred securities
will  be  reflected  on the  balance  sheet  as  "Company-obligated  mandatorily
redeemable  convertible  preferred  securities  of a  subsidiary  trust",  while
distributions  will be reflected in the  statements  of operations as a minority
interest captioned as "Distributions on trust preferred  securities".  The trust
preferred  securities accrue distributions at a rate of 5-3/4% per annum, have a
liquidation  value of $50.00  per  share,  are  convertible  into  shares of the
Company's common stock at a rate of 0.8565 shares of common stock for each trust
preferred security, and may be redeemed at any time on or after November 5, 2002
at a redemption  price equal to 101.44% of the principal amount plus any accrued
and  unpaid  interest  declining  to 100% of the  principal  amount  on or after
November 5, 2003. Additionally,  the Company has the right to defer the interest
payments on the debentures for up to twenty  consecutive  quarters,  which would
also  cause a  deferral  of  distributions  on the trust  preferred  securities.
Currently,  the Company has no intention of deferring  interest  payments on the
debentures.

On  November  3,  1999,  the  Company  entered  into  a $1.0  billion  revolving
construction  credit  facility with Credit Suisse First Boston,  New York branch
and The Bank of Nova Scotia, as lead arrangers. The non-recourse credit facility
will be utilized to finance the  construction  of its  diversified  portfolio of
gas-fired  power  plants  currently  under  development.  The Company  currently
intends to refinance this construction facility in the long-term capital markets
prior to its four-year maturity.

Management Overview

Calpine is engaged in the development,  acquisition, ownership, and operation of
power generation facilities and the sale of electricity and steam principally in
the United States.  At October 27, 1999, we had interests in 38 power plants and
steam fields predominantly in the United States, having an aggregate capacity of
3,694 megawatts.

On January 4, 1999, we completed the acquisition of a 20% interest in 82 billion
cubic feet of proven  natural gas reserves  located in the  Sacramento  basin of
Northern  California.  We paid approximately  $14.9 million for $13.0 million in
redeemable non-voting preferred stock and 20% of the outstanding common stock of
Sheridan California Energy, Inc ("SCEI"). Additionally, we signed a ten year gas
contract enabling us to purchase 100% of SCEI's production.

On  February  17,  1999,  we  announced  that the Delta  Energy  Center  met the
California Energy  Commission's Data Adequacy  requirements.  This ruling stated
that our Application for Certification  contained  adequate  information for the
California  Energy  Commission  to  begin  its  analysis  of the  power  plant's
environmental  impacts and proposed mitigation.  The Delta Energy Center, an 880
megawatt  gas-fired  power  plant  located  at  the  Dow  Chemical  facility  in
Pittsburg,  California,  is the first power plant that will be developed,  owned
and operated  under a joint venture with Bechtel  Enterprises,  and will provide
power to the  Pittsburg,  California  and greater San  Francisco  Bay Area.  The
gas-fired power plant is to be constructed by Bechtel and operated by us.

On February  17,  1999,  we  announced  plans to develop,  own and operate a 545
megawatt gas-fired power plant in Westbrook,  Maine. We acquired the development
rights for the Westbrook Power Plant from Genesis Power Corporation.  This power
plant is scheduled to begin power  deliveries by the end of 2000, and will serve
the New England market.

On February  24,  1999,  we  announced  plans to develop,  own and operate a 600
megawatt  gas-fired  power  plant  located in San Jose,  California.  This power
plant,  called  the  Metcalf  Energy  Center,  is the second  power  plant to be
developed  under the joint  venture with Bechtel  Enterprises,  and will provide
electricity to the San Francisco Bay area. We plan to commence  operation in mid
2002.

On March 19, 1999, we completed the acquisition of Unocal Corporation's  Geysers
geothermal steam fields in northern California for approximately $102.1 million.
The steam fields fuel our 12 Sonoma County

                                       13


power plants, totaling 544 megawatts of capacity. We purchased these plants from
Pacific  Gas and  Electric  Company  ("PG&E")  on May 7, 1999 (see Note 6 to the
Notes to Consolidated Financial Statements).

On April 14, 1999, we received approval from the California Energy Commission to
construct a 545 megawatt gas-fired power plant near Yuba City, California.  This
power  plant,  called  the Sutter  Power  Plant,  was the first new power  plant
approved in California's deregulated power industry. Electricity produced by the
Sutter Power Plant will be sold into  California's  energy market. We expect the
plant to commence operation in early 2001.

On April 22, 1999, we entered into a joint venture with GenTex Power Corporation
to develop,  own and  operate a 545  megawatt  gas-fired  power plant in Bastrop
County, Texas, called Lost Pines I. Construction of this power plant is expected
to begin in October 1999.  We will manage all phases of the plant's  development
process,  with GenTex and ourselves jointly operating the plant. The output from
Lost Pines I will be divided  equally,  with  GenTex  selling its portion to its
customer base,  while we will sell our portion to the wholesale  power market in
Texas. We expect the plant to commence operation in mid 2001.

On April 23, 1999, we entered into a joint  agreement with Pinnacle West Capital
Corporation  to develop,  own and operate a 545 megawatt  gas-fired  power plant
located in Phoenix,  Arizona.  This plant,  called the West Phoenix Power Plant,
will provide  power to the Phoenix  metropolitan  area,  and  construction  will
commence in 2000. We expect the plant to commence operation in 2002.

On May 7, 1999,  we completed  the  acquisitions  of 12 Sonoma County and 2 Lake
County  power  plants  from  PG&E.  The  approximate  purchase  price was $212.8
million.  The  acquisitions  were financed with a 24 year operating  lease.  Our
geothermal steam fields fuel the facilities,  which have a combined  capacity of
approximately  694  megawatts of  electricity.  All of the  generation  from the
facilities  is  sold to the  California  energy  market,  with  the  exceptionof
megawatts  sold  under  an  agreement  entered  into on  April  29,  1999,  with
Commonwealth  Energy Corporation as follows: 75 megawatts in 1999, 100 megawatts
in 2000, and 125 megawatts in 2001 and through June 2002. Historically,  we have
served as a steam  supplier  for  these  facilities,  which  had been  owned and
operated  by  PG&E.  These  acquisitions  have  enabled  us to  consolidate  our
operations  in The  Geysers  and to  integrate  the power  plant and steam field
operations,  allowing us to  optimize  the  efficiency  and  performance  of the
facilities.  We believe  that  these  acquisitions  provide us with  significant
synergies  that  leverage  our  expertise in  geothermal  power  generation  and
position  us to benefit  from the demand for "green"  energy in the  competitive
market.

On June 21,  1999,  we  acquired  the  rights  to build,  own and  operate a 545
megawatt gas-fired power plant located in Ontelaunee Township, Pennsylvania. The
plant, called the Ontelaunee Energy Center, will provide power to residences and
businesses   throughout  the   Pennsylvania-New   Jersey-Maryland   power  pool.
Construction  will  commence  in 2000  and  the  plant  is  scheduled  to  begin
production in 2002.

On August 20, 1999, we announced the purchase of 18 F-class combustion  turbines
from Siemens  Westinghouse  Power  Corporation that will be capable of producing
4,900 megawatts of electricity in a combined-cycle  configuration.  Beginning in
2002, Siemens will deliver six turbines per year through 2004. Combined with our
existing turbine order we now have 69 turbines under contract,  option or letter
of intent capable of producing 17,745 megawatts.

On August 27, 1999, we announced an agreement with  Cogeneration  Corporation of
America  ("CGCA")  to acquire  80% of its  common  stock for $25.00 per share or
approximately  $145.0 million.  NRG Energy,  Inc., a wholly owned  subsidiary of
Northern States Power, will own the remaining 20%. The transaction is subject to
the approval of CGCA shareholders and we expect to consummate the acquisition by
year end 1999.  CGCA  currently owns  interests in six natural  gas-fired  power
plants,  totaling 579  megawatts.  The plants are located in  Pennsylvania,  New
Jersey, Illinois and Oklahoma.

On August 31, 1999, we completed  the  acquisition  of an additional  50% of the
Aidlin Power Plant from Edison Mission Energy (5%) and General  Electric Capital
Corporation (45%) for a total purchase price of $7.2 million.  We now own 55% of
the 20 megawatt Aidlin Power Plant.

On  September  20, 1999,  the Board of Directors  authorized a two for one stock
split of our  common  stock,  to be  effected  in the form of a stock  dividend,
payable to  stockholders  of record on  September  23,  1999.  New  shares  were
distributed on October 7, 1999. In the Management's Discussion and Analysis, all
references  to the number of common shares and per share amounts have been split
adjusted.

On September 29, 1999, we completed the  acquisition  of  development  rights to
build, own and operate the Los Medanos Power Plant from Enron North America. The
Los Medanos Power Plant is a 550 megawatt  gas-fired  cogeneration plant located
adjacent to  USS-POSCO  Industries'  steel mill in  Pittsburg,  California.  Los
Medanos will supply USS-POSCO with 60 megawatts of electricity and 75,000 pounds
per hour of steam,  and market the excess  electricity into the California power
exchange and under bilateral contracts. Construction commenced in September 1999
and commercial operation is scheduled to occur in 2001.

On September  30,  1999,  we  announced  plans to build,  own and operate an 800
megawatt  gas-fired  cogeneration  power plant at Bayer  Corporation's  chemical
facility in Baytown,  Texas.  The Baytown Power Plant will supply Bayer with all
of  its  electric  and  steam  requirements  for  20  years  and  market  excess
electricity into the Texas wholesale power market.  Construction is estimated to
commence in 2000 and commercial operation in 2001.

Transactions Announced or Consummated Subsequent to September 30, 1999

On October 1, 1999, we completed the  acquisition  of Sheridan  Energy,  Inc., a
natural gas  exploration  and production  company,  through a $41.0 million cash
tender offer.  We purchased the outstanding  shares of Sheridan  Energy's common
stock for $5.50 per share. In addition, we redeemed $11.5 million of outstanding
preferred stock of Sheridan  Energy.  Sheridan  Energy's oil and gas properties,
including 148 billion cubic feet equivalent of proven  reserves,  are located in
northern California and the Gulf Coast region,  where we are developing low-cost
natural  gas  supplies  and   proprietary   pipeline   systems  to  support  our
strategically-located natural gas-fired power plants.

On October 21, 1999, we completed the  acquisition  of the Calistoga  geothermal
power plant from FPL Energy and Caithness  Corporation for  approximately  $78.0
million. The acquisition was financed with a 23-year operating lease. Located in
The Geysers region of northern  California,  Calistoga is a 67 megawatt facility
which provides electricity to PG&E under a long-term contract.

On October 25, 1999, we announced  that we had executed a letter of intent which
gives us the exclusive right to negotiate with  LYONDELL-CITGO  Refining L.P. to
build, own and operate a 560 megawatt gas-fired  cogeneration power plant at the
LYONDELL-CITGO refinery in Houston, Texas. The Channel Energy Center will supply
all of the  electricity  and steam  requirements  for 20 years to the  refinery.
Permitting for the facility is currently underway,  with construction  projected
to commence in early 2000 and commercial operation in 2001.

On November 2, 1999, we completed a public  offering of 7,200,000  shares of our
common  stock at $46.31 per share.  The net proceeds  from this public  offering
were  approximately  $320.3 million.  We sold an additional  1,080,000 shares of
common stock at $46.31 per share  pursuant to the exercise of the  underwriters'
over-allotment   option  for  net  proceeds  of  approximately   $48.2  million.
Concurrent with the public offering dated November 2, 1999, Calpine, through its
subsidiary  Calpine  Capital  Trust,  a statutory  business  trust created under
Delaware  law,  completed  an offering  of  4,800,000  Remarketable  Term Income
Deferrable Equity Securities ("trust preferred securities") at a value of $50.00
per share. The net proceeds from the offering were approximately $233.2 million.
We sold an additional  720,000 trust  preferred  securities at a value of $50.00
per share pursuant to the exercise of the  underwriters'  over-allotment  option
for net proceeds of  approximately  $35.0  million.  The net  proceeds  from the
offering were used by our subsidiary to invest in our  convertible  subordinated
debentures,  which represent  substantially  all of the subsidiary's  assets. We
have guaranteed all of the  subsidiary's  obligations  under the trust preferred
securities.  The trust  preferred  securities  will be  reflected on the balance
sheet  as  "Company-obligated   mandatorily   redeemable  convertible  preferred
securities of a subsidiary trust",  while distributions will be reflected in the
statements of operations as a minority  interest  captioned as "Distributions on
trust preferred securities". The trust preferred securities accrue distributions
at a rate of 5-3/4% per annum, have a


                                       15


liquidation  value of $50.00 per share,  are convertible  into shares of the our
common stock at a rate of 0.8565 shares of common stock for each trust preferred
security,  and may be  redeemed  at any time on or after  November  5, 2002 at a
redemption  price equal to 101.44% of the principal  amount plus any accrued and
unpaid interest  declining to 100% of the principal  amount on or after November
5, 2003. We have the right to defer the interest  payments on the debentures for
up to  twenty  consecutive  quarters,  which  would  also  cause a  deferral  of
distributions on the trust preferred securities.

On November 3, 1999,  we completed  the  acquisition  of  development  rights to
build,  own and operate the Towantic  Energy  Center from Arena Capital Ltd. The
Towantic Energy Center is a 500 megawatt gas-fired cogeneration plant located in
Oxford, Connecticut.  The Towantic Energy Center will market its electricity via
bilateral  contracts into the New England  region.  Construction is estimated to
commence in 2000 and commercial operation in 2002.

On November  3, 1999,  we entered  into a $1.0  billion  revolving  construction
credit facility with Credit Suisse First Boston, New York branch and The Bank of
Nova  Scotia,  as lead  arrangers.  The  non-recourse  credit  facility  will be
utilized to finance the  construction of our diversified  portfolio of gas-fired
power plants currently under  development.  We currently intend to refinance the
construction  facility in the long-term  capital  markets prior to its four-year
maturity.

Megawatt hours produced at the power plants  increased 42% and 80% for the three
and nine months ended  September  30, 1999 as compared  with the same periods in
1998.  The three month  increase was primarily due to additional  megawatt hours
produced at the 14 geothermal  power plants  purchased from PG&E on May 7, 1999.
The increase for the nine months ended September 30, 1999 includes the effect of
the  geothermal  plants  acquired  from  PG&E,  as well as the  start  up of the
Pasadena  Power  Plant,  and the


                                       16


acquisitions of the Texas City, Clear Lake,  Pittsburg and Bethpage Power Plants
in 1998.

Due to the consolidation of the power plants purchased from PG&E on May 7, 1999,
the revenue previously  recognized for the Steam Fields will now be incorporated
in our Power Plants revenue.

Revenue -- Total  revenue  increased  42% and 57% to $263.6  million  and $600.2
million for the three months and nine months ended  September  30, 1999 compared
to $186.2 million and $382.9 million in 1998.

     Electricity and steam sales revenue increased 34% to $225.4 million for the
three months ended  September  30, 1999  compared to $168.6  million in the same
period in 1998. The increase is primarily  attributable to the  consolidation of
our Geysers  operation in Northern  California during the first half of calendar
1999, which increased  electricity revenues by $71.9 million. The Pasadena Power
Plant,  which became  operational  in July 1998,  contributed  $22.1  million in
additional  revenue during 1999.  These  increases  were  partially  offset by a
decrease  of $9.6  million at the Bear  Canyon  and West Ford Flat Power  Plants
relating  to the  expiration  of the fixed  priced  period of their  power sales
agreements.  Consequently,


                                       17


the price of electricity  for these two power plants was  significantly  reduced
compared  to the price for the same  period  in 1998.  Furthermore,  there was a
$12.0 million  reduction in steam revenues  related to the  consolidation of the
PG&E power plants  acquired on May 7, 1999. For the nine months ended  September
30, 1999,  electricity  and steam  revenues  increased 53% to $529.8  million as
compared to $347.4 million for the same period a year ago.  These  increases are
primarily due an increase of $171.2  million for power plants that were acquired
during  1998 and 1999,  and $40.5  million  for our  Pasadena  Plant that became
operational  in the third  quarter of 1998,  partially  offset by a decrease  of
$31.5 million at the Bear Canyon and West Ford Flat Power Plants relating to the
expiration of the fixed priced period of their power sales agreements.

Service  contract  revenue  increased to $21.8 million and $35.1 million for the
three and nine months  ended  September  30, 1999  compared to $7.8  million and
$16.4  million  for the  same  periods  in  1998.  The  increase  was  primarily
attributable  to a reclass  made to record year to date third party gas sales as
revenue rather than netted against gas purchases.

Income from unconsolidated  investments in power projects increased 62% to $15.8
million for the three months ended  September  30, 1999 compared to $9.8 million
for the same  period in 1998.  The  increase  is  primarily  attributable  to an
increase of $4.8 million of equity income from our investment in Sumas, and $1.0
million of additional  equity income from our  investments in the Auburndale and
Gordonsville  Power Plants. For the nine months ended September 30, 1999, income
from  unconsolidated  investments  in  power  projects  increased  105% to $34.2
million  as  compared  to $16.6  million  for the same  period a year ago.  This
increase is  primarily  attributable  to an increase of $16.2  million of equity
income from our  investment  in Sumas,  and  increase of $1.3  million of equity
income from our  investment  in the Bayonne  Power  Plant,  and increase of $1.4
million of equity income from our investments in the Auburndale and Gordonsville
Power  Plants,  and an  increase  of $1.0  million  of  equity  income  from our
investment in the Kennedy  International  Airport Power Plant.  These  increases
were  partially  offset by a reduction of $2.9 million in equity income from our
Texas City and Clear Lake Power  Plants,  which were  consolidated  on March 31,
1998 (see Note 4 to the Notes to Consolidated Financial Statements).

     Interest  income  on loans to power  projects  was  $517,000  for the three
months ended  September 30, 1999 and is attributable to dividend income received
from Sheridan  California Energy, Inc. We will no longer receive dividend income
from SCEI due to the acquisition and consolidation of Sheridan Energy on October
1, 1999. For the nine months ended September 30, 1999,  interest income on loans
to power  projects  decreased to $1.2  million  compared to $2.6 million for the
same period a year ago. The decrease is primarily  related to the acquisition of
the  remaining  50%  interest in Texas  Cogeneration  Company on March 31, 1998,
offset by dividend income received from SCEI.

Cost of  revenue  -- Cost of  revenue  increased  to $159.8  million  and $398.0
million  for the three and nine months  ended  September  30,  1999  compared to
$117.1 million and $253.2 million for the same periods in 1998. The increases of
$42.7 million and $144.8 million were primarily  attributable to increased plant
operating,  and fuel  expenses as a result of the  acquisition  of the remaining
interests in the Texas City and Clear Lake Power  Plants on March 31, 1998,  the
acquisition of the remaining interest in the Bethpage Power Plant on February 5,
1998,  the  acquisition  of the  Pittsburg  Power  Plant on July 21,  1998,  the
consolidation  of our Geysers  operations on May 7, 1999, and the startup of the
Pasadena Power Plant in July of 1998.

General  and  administrative  expenses -- General  and  administrative  expenses
increased  to $13.3  million  for the three  months  ended  September  30,  1999
compared to $7.4 million in 1998. For the nine months ended  September 30, 1999,
general and administrative expenses increased to $34.3 million compared to $18.4
million  for the same  period  in  1998.  The  increases  were  attributable  to
continued  growth in  personnel,  compensation  and  associated  overhead  costs
necessary to support the overall growth in our operations.

Interest expense -- Interest expense decreased 6% to $23.0 million for the three
months ended  September 30, 1999 from $24.3 million for the same period in 1998.
The decrease was primarily  attributable to an increase in capitalized  interest
of $15.3 million in connection with the construction of power plants as compared
to the same  period in 1998,  partially  offset  by $11.7  million  of  interest
associated  with the issuance of senior notes in 1999. For the nine months ended
September  30, 1999,  interest  expense


                                       18


increased to $70.2  million  from $65.1  million for the same period a year ago.
The increase was primarily  attributable to $33.5 million of interest associated
with the  issuances  of senior  notes in 1999 and 1998,  partially  offset by an
increase in capitalized  interest of $22.4  million,  and a decrease in interest
expense  of $5.2  million  related to the  retirement  of  non-recourse  project
financing  for the  Greenleaf  Power Plant in 1998 and the Gilroy Power Plant in
1999.

Provision  for income taxes -- The effective  income tax rate was  approximately
39% for the three and nine months ended  September 30, 1999. The reductions from
the  statutory  tax rate were  primarily due to depletion in excess of tax basis
benefits at our geothermal  facilities,  and a decrease in the average state tax
rate due to our expansion into states other than California.

Liquidity and Capital Resources

To date, we have obtained cash from our operations,  borrowings under our credit
facilities  and  other  working  capital  lines,  sale of debt and  equity,  and
proceeds from non-recourse project financing.  We utilized this cash to fund our
operations,  service debt obligations, fund acquisitions,  develop and construct
power  generation  facilities,  finance capital  expenditures and meet our other
cash  and  liquidity  needs.  The  following  table  summarizes  our  cash  flow
activities for the periods indicated:

     Operating  activities  for 1999  provided  $166.2  million,  consisting  of
approximately  $64.2 million of net income,  $59.2 million of  depreciation  and
amortization,  $34.2 million of distributions from unconsolidated investments in
power  projects,  $40.5 million of deferred  income  taxes,  a $42.4 million net
increase in  operating  liabilities,  and a loss on sale of assets of  $364,000.
This was offset by $40.6  million  net  increase in  operating  assets and $34.2
million of income from unconsolidated investments.

     Investing activities for 1999 used $881.0 million,  primarily due to $102.2
million for the  acquisition of steam fields from Unocal,  $50.9 million for the
acquisition  of Sheridan  Energy Inc.,  $7.2 million for the  acquisition  of an
additional  50%  interest  in the Aidlin  Power  Plant,  $14.9  million  for the
acquisition of a 20% interest in Sheridan  California  Energy Inc.,  advances to
the Lost  Pines I Joint  Venture  of $14.8  million,  $112.6  million of capital
expenditures  related to the construction of the Pasadena Power Plant Expansion,
$555.4 million of other capital  expenditures  principally for turbine purchases
and for the Clear Lake Expansion project,  $16.0 million of capitalized  project
development  costs,  $29.3  million  of  interest  capitalized  on  construction
projects,  $8.2 million of additional loans to principal owners of power plants,
$655,000 for the acquisition of additional  investments,  offset by $1.9 million
in maturities of  collateral  securities in connection  with the King City Power
Plant,  the  repayment  of $3.1  million of  outstanding  loans,  a $7.7 million
decrease in  restricted  cash,  and $18.4  million  from the sale and  leaseback
transaction of the Geysers Power Company plants.

     Financing activities for 1999 provided $791.9 million of cash consisting of
$115.2 million of borrowings for the  construction  of the Pasadena Power Plant,
$77.6  million of  borrowings  related to a bridge  facility,  $51.0  million in
borrowings of  non-recourse  project  financing,  $792.1 million of net proceeds
from additional equity and senior debt financings received in March and April of
1999,  $2.3  million for the  issuance of common  stock for our  Employee  Stock
Purchase Plan, and $1.9 million for the write off of deferred financing costs in
April 1999,  partially  offset by $170.6  million in repayment  of  non-recourse
project  financing in April 1999,  and $77.6 million of repayments  related to a
bridge facility.

                                       19


     At September 30, 1999,  cash and cash  equivalents  were $173.7 million and
working  capital  was  $171.0  million.  For  1999,  cash and  cash  equivalents
increased by $77.1  million and working  capital  increased by $84.0  million as
compared to December 31, 1998.

     As a developer,  owner and operator of power generation facilities,  we are
required to make long-term  commitments and  investments of substantial  capital
for our projects.  We historically have financed these capital requirements with
cash from  operations,  borrowings under our credit  facilities,  other lines of
credit,  construction  financing,  non-recourse  project  financing or long-term
debt, and the sale of equity.

     We  continue to evaluate  current and  forecasted  cash flow as a basis for
financing operating  requirements and capital  expenditures.  We believe that we
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.

    On January 4, 1999, the Company entered into a Credit Agreement  with ING to
provide  up  to  $265.0  million  of  non-recourse  project  financing  for  the
construction  of the Pasadena Power Plant  expansion.  As of September 30, 1999,
$115.2 million was outstanding as a construction  loan under the agreement.  The
outstanding loan bears interest at ING's base rate plus an applicable  margin or
at LIBOR plus an applicable  margin and is payable  quarterly.  The construction
loan will  convert to a term loan once the project has  completed  construction.
The  construction  loan will mature on or before July 1, 2000, but is subject to
an  extension  to October  1, 2000 if there are  sufficient  construction  funds
available. The term loan will be available for a period not to exceed five years
from the  construction  loan  maturity  date.  In  connection  with  the  Credit
Agreement,  the Company entered into a $10.0 million letter of credit  facility.
At September  30, 1999,  there were no letters of credit  outstanding  under the
facility.

     On March 26, 1999, we completed a public  offering of 12,000,000  shares of
our common stock at $15.50 per share. All share information reflects the two for
one stock split  effective on October 7, 1999. The net proceeds from this public
offering were approximately $177.9 million. Additionally, in April 1999, we sold
an additional  1,800,000  shares of common stock at $15.50 per share pursuant to
the  exercise of the  underwriters'  over-allotment  option for net  proceeds of
approximately $26.7 million.

     On March 29, 1999, we completed a public  offering of $250.0 million of our
7-5/8% Senior Notes Due 2006 and of our $350.0  million  7-3/4% Senior Notes Due
2009. After deducting  underwriting  discounts and expenses of the offering, the
aggregate  net  proceeds  from the sale of the Senior  Notes were  approximately
$587.5  million.  The Senior  Notes Due 2006 bear  interest  at 7-5/8% per year,
payable  semi-annually  on April 15 and October 15 each year and mature on April
15, 2006.  The Senior Notes Due 2006 are not redeemable  prior to maturity.  The
Senior Notes Due 2009 bear interest at 7-3/4% per year, payable semi-annually on
April 15 and October 15 each year and mature on April 15, 2009. The Senior Notes
Due 2009 are not redeemable prior to maturity.

     The net proceeds  from the sale of the common  stock,  the Senior Notes Due
2006, and the Senior Notes Due 2009 were used as follows:  (i) $120.6 million to
refinance indebtedness relating to the Gilroy Power Plant, (ii) $77.6 million to
repay  indebtedness  under a bridge  facility  provided by Credit  Suisse  First
Boston to finance a portion of the  purchase  price to acquire the steam  fields
that  service the Sonoma  County  power  plants,  (iii)  $50.0  million to repay
outstanding  borrowings under our revolving credit facility,  (iv) $25.0 million
to complete  the  expansion  of the Clear Lake Power  Plant,  (v)  approximately
$400.0  million to finance a portion of power  generation  facilities  currently
under construction and the projects  currently under  development,  and (vi) the
remaining  $118.9  million  will  be  used  for  general   corporate   purposes.
Transaction  costs  incurred in connection  with the Senior Notes  offering were
recorded as a deferred charge and are amortized over the respective lives of the
Senior Notes Due 2006 and the Senior Notes Due 2009 using the effective interest
rate method.

     At September 30, 1999,  we also had $105.0  million of  outstanding  9-1/4%
Senior Notes Due 2004,  which mature on February 1, 2004, with interest  payable
semi-annually  on  February  1 and August 1 of each year.  In  addition,  we had
$171.8 million of outstanding 10-1/2% Senior Notes Due 2006, which mature on


                                       20


May 15, 2006, with interest  payable  semi-annually on May 15 and November 15 of
each year.  During 1997,  we issued  $275.0  million of 8-3/4%  Senior Notes Due
2007,  which mature on July 15, 2007,  with interest  payable  semi-annually  on
January 15 and July 15 of each year.  During 1998, we issued  $400.0  million of
7-7/8%  Senior  Notes Due 2008,  which  mature on April 1, 2008,  with  interest
payable semi-annually on April 1 and October 1 of each year.

     At September 30, 1999, we had a $100.0 million  revolving  credit  facility
available  with a  consortium  of  commercial  lending  institutions.  We had no
borrowings and $26.0 million of letters of credit  outstanding  under the credit
facility (See Note 8 to the Notes to  Consolidated  Financial  Statements).  The
credit facility  contains  certain  restrictions  that limit or prohibit,  among
other  things,  our  ability 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, 1999, we had a $12.0 million letter of credit  outstanding
with The Bank of Nova  Scotia to secure  performance  of the  Clear  Lake  Power
Plant.

Outlook

     Our  strategy  is to  continue  our  rapid  growth by  capitalizing  on the
significant  opportunities in the power industry,  primarily  through our active
development and acquisition programs. In pursuing our proven growth strategy, we
utilize our extensive  management  and technical  expertise to implement a fully
integrated  approach to the  acquisition,  development  and  operation  of power
generation facilities.  This approach uses our expertise in design, engineering,
procurement,  finance,  construction management,  fuel and resource acquisition,
operations and power  marketing,  which we believe provide us with a competitive
advantage. The key elements of our strategy are as follows:

*    Development  and  expansion of power plants.  We are actively  pursuing the
     development and expansion of highly  efficient,  low-cost,  gas-fired power
     plants that replace old and inefficient  generating facilities and meet the
     demand for new  generation.  Our  strategy  is to develop  power  plants in
     strategic  geographic  locations that enable us to leverage  existing power
     generation  assets and  operate  the power  plants as  integrated  electric
     generation  systems.  This  allows  us  to  achieve  significant  operating
     synergies  and  efficiencies  in  fuel  procurement,  power  marketing  and
     operations and maintenance.

     We currently  have  nine new  projects under construction, representing  an
     additional  4,485  megawatts of  capacity.  Of these new  projects,  we are
     expanding  our Pasadena  facility by 545  megawatts to 785 megawatts and we
     have eight new power  plants  under  construction,  including  the Tiverton
     Power  Plant in Rhode  Island;  the  Rumford  Power  Plant  in  Maine;  the
     Westbrook Power Plant in Maine;  the Sutter Power Plant in California;  the
     Los  Medanos  Power  Plant in  California;  the South  Point Power Plant in
     Arizona;  the Magic Valley Power Plant in Texas; and the Lost Pines I Power
     Plant in Texas.  We have also  announced  plans to develop  six  additional
     power  generation  facilities,  totaling  4,430  megawatts,  in California,
     Connecticut, Texas, Arizona and Pennsylvania.

*    Acquisition  of power plants.  Our strategy is to acquire power  generating
     facilities  that  meet  our  stringent  acquisition  criteria  and  provide
     significant  potential for revenue, cash flow and earnings growth, and that
     provide  the  opportunity  to enhance  the  operating  efficiencies  of the
     plants.  We  have  significantly   expanded  and  diversified  our  project
     portfolio  through the acquisition of power generation  facilities  through
     the completion of 32 acquisitions to date.

*    Enhance the  performance  and  efficiency of existing  power  projects.  We
     continually  seek  to  maximize  the  power  generation  potential  of  our
     operating  assets and minimize our operating and  maintenance  expenses and
     fuel costs.  This will become even more  significant  as our  portfolio  of
     power generation facilities expands to an aggregate of 52 power plants with
     an aggregate capacity of approximately 8,758 megawatts, after completion of
     our pending  acquisitions  and projects  currently under  construction.  We
     focus on operating our plants as an integrated  system of power generation,
     which enables us to minimize costs and maximize operating efficiencies.  We
     believe that  achieving


                                       21


     and  maintaining a low-cost of production will be increasingly important to
     compete effectively in the power generation industry.

Risk Factors

     We have substantial  indebtedness that we may be unable to service and that
restricts our activities.  We have  substantial debt that we incurred to finance
the acquisition and development of power generation facilities.  As of September
30,  1999 our  total  consolidated  indebtedness  was $1.7  billion,  our  total
consolidated  assets were $2.7 billion and our  stockholders'  equity was $558.0
million.  Whether we will be able to meet our debt  service  obligations  and to
repay  our  outstanding  indebtedness  will  be  dependent  primarily  upon  the
performance of our subsidiaries.

     This high level of indebtedness has important consequences, including:

*    limiting  our ability to borrow  additional  amounts  for working  capital,
     capital expenditures,  debt service  requirements,  execution of our growth
     strategy, or other purposes,
*    limiting  our  ability  to use  operating  cash flow in other  areas of our
     business  because we must dedicate a substantial  portion of these funds to
     service the debt,
*    increasing  our  vulnerability  to general  adverse  economic  and industry
     conditions, and
*    limiting our ability to capitalize on business  opportunities  and to react
     to competitive pressures and adverse changes in government regulation.

     The operating and financial restrictions and covenants in our existing debt
agreements,  including  the  indentures  relating to our $1.6 billion  aggregate
principle  amount  of senior  notes  and our  $100.0  million  revolving  credit
facility,  contain restrictive covenants.  Among other things these restrictions
limit or prohibit our ability to:

*    incur indebtedness,
*    make prepayments of indebtedness in whole or in part,
*    pay dividends,
*    make investments,
*    engage in transactions with affiliates,
*    create liens,
*    sell assets, and
*    acquire facilities or other businesses.

     Also, if our management or ownership changes,  our indentures governing our
senior  notes may require us to make an offer to purchase our senior  notes.  We
cannot  assure  you  that we will  have the  financial  resources  necessary  to
purchase our senior notes in this event.

     We  believe  that  our cash  flow  from  operations,  together  with  other
available sources of funds,  including  borrowings under our existing  borrowing
arrangements,  will be adequate to pay principal and interest on our debt and to
enable us to comply with the terms of our debt  agreements.  If we are unable to
comply with the terms of our debt  agreements  and fail to  generate  sufficient
cash flow from operations in the future,  we may be required to refinance all or
a portion of our senior notes and other debt or to obtain additional  financing.
However, we may be unable to refinance or obtain additional financing because of
our high  levels  of debt and the debt  incurrence  restrictions  under our debt
agreements. If cash flow is insufficient and refinancing or additional financing
is  unavailable,  we may be forced to default on our senior notes and other debt
obligations.  In  the  event  of a  default  under  the  terms  of  any  of  our
indebtedness,  the debt holders may accelerate the maturity of our  obligations,
which could cause defaults under our other obligations.

     Our  ability  to  repay  our  debt  depends  upon  the  performance  of our
subsidiaries.   Almost  all  of  our  operations   are  conducted   through  our
subsidiaries and other  affiliates.  As a result, we depend almost entirely upon
their earnings and cash flow to service our indebtedness,  including our ability
to pay the interest on and principal of our senior notes.  Non-recourse  project
financing  agreements  generally  restrict


                                       22


our ability to pay dividends,  make distributions or otherwise transfer funds to
us prior to the payment of other obligations, including operating expenses, debt
service and reserves.

     Our  subsidiaries  and other  affiliates  are separate  and distinct  legal
entities and have no obligation to pay any amounts due on our senior notes,  and
do not  guarantee  the payment of interest on or principal  of these notes.  The
right  of  our  senior  note  holders  to  receive  any  assets  of  any  of our
subsidiaries or other affiliates upon our liquidation or reorganization  will be
subordinated to the claims of any subsidiaries' or other  affiliates'  creditors
(including  trade  creditors and holders of debt issued by our  subsidiaries  or
affiliates).  As of September 30, 1999, our  subsidiaries  had $115.2 million of
construction   financing.   We  intend  to  utilize   non-recourse  project  and
construction  financing  in the future  that will be  effectively  senior to our
senior notes.

     While the indentures  impose  limitations on our ability and the ability of
our subsidiaries to incur additional  indebtedness,  the indentures do not limit
the amount of non-recourse  project financing that our subsidiaries may incur to
finance new power generation facilities.

     We may be unable to secure additional  financing in the future.  Each power
generation  facility that we acquire or develop will require substantial capital
investment.  Our ability to arrange  financing and the cost of the financing are
dependent upon numerous factors. These factors include:

*    general economic and capital market conditions,
*    conditions in energy markets,
*    regulatory developments,
*    credit availability from banks or other lenders,
*    investor confidence in the industry and in us,
*    the continued success of our current power generation facilities, and
*    provisions  of tax and  securities  laws  that  are  conducive  to  raising
     capital.

     Financing for new facilities may not be available to us on acceptable terms
in the future. We have financed our existing power generation facilities using a
variety of sources,  primarily  consisting of  non-recourse  project  financing,
lease  obligations,  and  from  the  proceeds  of our  senior  debt  and  equity
issuances.  As of September 30, 1999, we had approximately $1.7 billion of total
consolidated  indebtedness,  $115.2  million of which  represented  construction
financing. Each construction financing, non-recourse project financing and lease
obligation  is  structured  to be fully  paid out of cash flow  provided  by the
facility or  facilities.  In the event of a default under a financing  agreement
which we do not cure, the lenders or lessors would  generally have rights to the
facility and any related assets. In the event of foreclosure after a default, we
might not  retain  any  interest  in the  facility.  While we intend to  utilize
non-recourse or lease financing when  appropriate,  market  conditions and other
factors may prevent similar financing for future  facilities.  We do not believe
the existence of non-recourse or lease financing will  significantly  affect our
ability  to  continue  to borrow  funds in the  future in order to  finance  new
facilities.  However,  it is  possible  that  we may be  unable  to  obtain  the
financing  required  to  develop  our  power  generation   facilities  on  terms
satisfactory to us.

     We  have  from  time  to  time  guaranteed   certain   obligations  of  our
subsidiaries and other affiliates. Our lenders or lessors may also require us to
guarantee the indebtedness for future facilities.  This would render our general
corporate funds  vulnerable in the event of a default by the facility or related
subsidiary.  Additionally,  our indentures may restrict our ability to guarantee
future debt,  which could  adversely  affect our ability to fund new facilities.
Our  indentures  do  not  limit  the  ability  of  our   subsidiaries  to  incur
non-recourse or lease financing for investment in new facilities.

     Revenue  under  some  of  our  power  sales   agreements   may  be  reduced
significantly  upon their expiration or termination.  Most of the electricity we
generate  from our  existing  portfolio  is sold  under  long-term  power  sales
agreements  that expire at various times.  When the terms of each of these power
sales  agreements  expire,  it is  possible  that the  price  paid to us for the
generation   of   electricity   may  be  reduced   significantly,   which  would
substantially reduce our revenue under such agreements.  The fixed price periods
in some of our long-term power sales agreements have recently  expired,  and the
electricity  under


                                       23


those  agreements is now sold at a fluctuating  market price.  For example,  the
price  for  electricity  for  two of our  power  plants,  the  Bear  Canyon  (20
megawatts) and the West Ford Flat (27 megawatts) power plants, was approximately
13.83  cents per  kilowatt  hour under the fixed  price  periods  that  recently
expired for these facilities, and is now set at the energy clearing price, which
averaged  2.61 cents per kilowatt  hour for the nine months ended  September 30,
1999. As a result,  our energy  revenue under these power sales  agreements  has
been  materially  reduced.  We expect  the  decline in energy  revenues  will be
partially mitigated by decreased royalties and planned operating cost reductions
at these  facilities.  In addition,  we will continue our strategy of offsetting
these reductions through our acquisition and development program.

     Our  power  project  development  and  acquisition  activities  may  not be
successful.  The  development  of power  generation  facilities  is  subject  to
substantial  risks.  In connection  with the  development of a power  generation
facility, we must generally obtain:

*    necessary power generation equipment,
*    governmental permits and approvals,
*    fuel supply and transportation agreements,
*    sufficient equity capital and debt financing,
*    electrical transmission agreements, and
*    site agreements and construction contracts.

     We may be unsuccessful in accomplishing any of these matters or in doing so
on a timely  basis.  In  addition,  project  development  is  subject to various
environmental,  engineering and  construction  risks relating to  cost-overruns,
delays and performance.  Although we may attempt to minimize the financial risks
in the development of a project by securing a favorable  power sales  agreement,
obtaining all required governmental permits and approvals and arranging adequate
financing prior to the commencement of construction,  the development of a power
project  may  require  us  to  expend   significant   amounts  for   preliminary
engineering,  permitting  and legal and other  expenses  before we can determine
whether a project is feasible,  economically  attractive or  financeable.  If we
were unable to complete the development of a facility, we would generally not be
able to recover our investment in the project. The process for obtaining initial
environmental,   siting  and  other   governmental   permits  and  approvals  is
complicated  and  lengthy,  often  taking more than one year,  and is subject to
significant  uncertainties.  We cannot  assure you that we will be successful in
the development of power generation facilities in the future.

     We have grown  substantially in recent years as a result of acquisitions of
interests  in power  generation  facilities  and steam  fields.  We believe that
although  the  domestic  power  industry is  undergoing  consolidation  and that
significant  acquisition  opportunities are available, we are likely to confront
significant  competition for acquisition  opportunities.  In addition, we may be
unable to continue to identify attractive acquisition opportunities at favorable
prices or, to the extent that any opportunities are identified, we may be unable
to complete the acquisitions.

     Our projects under  construction  may not commence  operation as scheduled.
The commencement of operation of a newly constructed  power generation  facility
involves many risks, including:

*    start-up problems,
*    the breakdown or failure of equipment or processes, and
*    performance below expected levels of output or efficiency.

     New plants have no operating history and may employ recently  developed and
technologically  complex  equipment.  Insurance is maintained to protect against
certain risks, warranties are generally obtained for limited periods relating to
the  construction  of each  project and its  equipment in varying  degrees,  and
contractors  and equipment  suppliers are obligated to meet certain  performance
levels. The insurance, warranties or performance guarantees, however, may not be
adequate to cover lost revenues or increased  expenses.  As a result,  a project
may be  unable to fund  principal  and  interest  payments  under its  financing
obligations  and may  operate  at a  loss.  A  default  under  such a  financing
obligation could result in losing our interest in a power generation facility.

                                       24


     In addition,  power sales  agreements  entered into with a utility early in
the  development  phase of a project  may enable the  utility to  terminate  the
agreement,  or to retain  security  posted as liquidated  damages,  if a project
fails to achieve  commercial  operation or certain operating levels by specified
dates or if we fail to make specified payments. In the event a termination right
is exercised,  the default provisions in a financing  agreement may be triggered
(rendering such debt immediately due and payable).  As a result, the project may
be rendered insolvent and we may lose our interest in the project.

     Our power generation facilities may not operate as planned. Upon completion
of our pending  acquisitions and projects currently under construction,  we will
operate  42 of the 52  power  plants  in  which we will  have an  interest.  The
continued  operation  of  power  generation   facilities  involves  many  risks,
including the breakdown or failure of power generation  equipment,  transmission
lines,  pipelines or other equipment or processes and performance below expected
levels of output or efficiency.  Although from time to time our power generation
facilities have experienced  equipment breakdowns or failures,  these breakdowns
or failures have not had a significant effect on the operation of the facilities
or on our results of operations.  For the nine months ended  September 30, 1999,
our  gas-fired  power   generation   facilities  have  operated  at  an  average
availability of approximately 93% and our geothermal power generation facilities
have operated at an average  availability  of  approximately  97%.  Although our
facilities contain various  redundancies and back-up mechanisms,  a breakdown or
failure may prevent the facility from performing  under  applicable  power sales
agreements.  In addition,  although  insurance is maintained to protect  against
operating  risks,  the proceeds of  insurance  may not be adequate to cover lost
revenues  or  increased  expenses.  As a result,  we could be unable to  service
principal  and interest  payments  under our financing  obligations  which could
result in losing our interest in the power generation facility.

     Our geothermal  energy reserves may be inadequate for our  operations.  The
development  and  operation  of  geothermal  energy  resources  are  subject  to
substantial  risks  and  uncertainties  similar  to  those  experienced  in  the
development  of  oil  and  gas  resources.  The  successful  exploitation  of  a
geothermal energy resource ultimately depends upon:

*    the heat content of the extractable fluids,
*    the geology of the reservoir,
*    the total amount of recoverable reserves,
*    operating expenses relating to the extraction of fluids,
*    price levels relating to the extraction of fluids, and
*    capital expenditure  requirements relating primarily to the drilling of new
     wells.

     In  connection   with  each   geothermal   power  plant,  we  estimate  the
productivity   of  the   geothermal   resource  and  the  expected   decline  in
productivity.  The  productivity of a geothermal  resource may decline more than
anticipated,  resulting in  insufficient  reserves being available for sustained
generation of the electrical power capacity desired. An incorrect estimate by us
or and unexpected decline in productivity could lower our results of operations.

     Geothermal reservoirs are highly complex. As a result, there exist numerous
uncertainities  in determining the extent of the reservoirs and the quantity and
productivity of the steam reserves.  Reservoir engineering is an inexact process
of  estimating  underground  accumulations  of steam or  fluids  that  cannot be
measured in any precise  way,  and depends  significantly  on the  quantity  and
accuracy of  available  data.  As a result,  the  estimates  of other  reservoir
specialists may differ materially from ours. Estimates of reserves are generally
revised  over  time  on the  basis  of the  results  of  drilling,  testing  and
production  that occur after the original  estimate was prepared.  While we have
extensive  experience  in the  operation and  development  of geothermal  energy
resources and in preparing such estimates,  we cannot assure you that we will be
able to  successfully  manage the  development  and operation of our  geothermal
reservoirs or that we will  accurately  estimate the quantity or productivity of
our steam reserves.

     We depend on our  electricity  and thermal  energy  customers.  Each of our
power  generation  facilities  currently  relies  on one  or  more  power  sales
agreements with one or more utility or other customers for all or  substantially
all of such  facility's  revenue.  In addition,  the sales of electricity to two
utility  customers during the first nine months of 1999 comprised  approximately
47% of our total  revenue  during that  period.


                                       25


The loss of any one power sales agreement with any of these customers could have
a negative  effect on our  results of  operations.  In  addition,  any  material
failure by any customer to fulfill its obligations under a power sales agreement
could have a negative effect on the cash flow available to us and our results of
operations.

     We are  subject to complex  government  regulation  which  could  adversely
affect our  operations.  Our  activities  are subject to complex  and  stringent
energy,   environmental  and  other  governmental  laws  and  regulations.   The
construction  and  operation of power  generation  facilities  require  numerous
permits,  approvals and certificates from appropriate  federal,  state and local
governmental  agencies,  as well as  compliance  with  environmental  protection
legislation  and other  regulations.  While we believe that we have obtained the
requisite  approvals  for our  existing  operations  and  that our  business  is
operated in accordance with  applicable  laws, we remain subject to a varied and
complex  body of laws and  regulations  that both public  officials  and private
individuals may seek to enforce. Existing laws and regulations may be revised or
new laws and  regulations  may become  applicable to us that may have a negative
effect on our business and results of operations. We may be unable to obtain all
necessary licenses,  permits,  approvals and certificates for proposed projects,
and completed  facilities may not comply with all applicable permit  conditions,
statutes or regulations. In addition, regulatory compliance for the construction
of new facilities is a costly and time-consuming process. Intricate and changing
environmental  and other  regulatory  requirements  may necessitate  substantial
expenditures  to obtain  permits.  If a project is unable to function as planned
due to changing requirements or local opposition, it may create expensive delays
or significant loss of value in a project.

     Our operations are potentially  subject to the provisions of various energy
laws and regulations,  including the Public Utility  Regulatory  Policies Act of
1978, as amended  ("PURPA"),  the Public Utility Holding Company Act of 1955, as
amended  ("PUHCA"),  and state and local  regulations.  PUHCA  provides  for the
extensive regulation of public utility holding companies and their subsidiaries.
PURPA  provides to  qualifying  facilities  ("QFs") (as defined under PURPA) and
owners of QFs certain  exemptions  from certain  federal and state  regulations,
including rate and financial regulations.

     Under  present  federal law, we are not subject to  regulation as a holding
company under PUHCA,  and will not be subject to such  regulation as long as the
plants in which we have an  interest  (1)  qualify  as QFs,  (2) are  subject to
another  exemption  or waiver or (3)  qualify  as  exempt  wholesale  generators
("EWG")  under the Energy  Policy  Act of 1992.  In order to be a QF, a facility
must be not more than 50%  owned by an  electric  utility  company  or  electric
utility holding company. In addition, a QF that is a cogeneration facility, such
as the plants in which we currently have interests,  must produce electricity as
well as  thermal  energy  for use in an  industrial  or  commercial  process  in
specified  minimum  proportions.  The QF also must meet certain  minimum  energy
efficiency  standards.  Any  geothermal  power  facility which produces up to 80
megawatts of electricity and meets PURPA ownership  requirements is considered a
QF.

     If any of the plants in which we have an  interest  lose their QF status or
if  amendments  to PURPA are  enacted  that  substantially  reduce the  benefits
currently afforded QFs, we could become a public utility holding company,  which
could subject us to significant federal,  state and local regulation,  including
rate regulation.  If we become a holding company, which could be deemed to occur
prospectively  or  retroactively to the date that any of our plants loses its QF
status,  all our other power  plants  could lose QF status  because,  under FICC
regulations,  a QF cannot be owned by an electric  utility or  electric  utility
holding  company.  In  addition,  a loss of QF status  could,  depending  on the
particular power purchase  agreement,  allow the power purchaser to cease taking
and paying for  electricity  or to seek  refunds of past  amounts  paid and thus
could cause the loss of some or all contract  revenues or  otherwise  impair the
value of a project.  If a power  purchaser  were to cease  taking and paying for
electricity  or seek to obtain  refunds of past  amounts  paid,  there can be no
assurance  that the costs  incurred  in  connection  with the  project  could be
recovered through sales to other purchasers.  Such events could adversely affect
our ability to service our indebtedness, including our senior notes.

     Currently,  Congress is considering  proposed  legislation that would amend
PURPA by eliminating the requirement  that utilities  purchase  electricity from
QFs at prices  based on avoided  costs of energy.  We do


                                       26


not know whether this legislation will be passed or, if passed, what form it may
take. We cannot assure that any  legislation  passed would not adversely  impact
our existing domestic projects.

     In  addition,  many  states  are  implementing  or  considering  regulatory
initiatives  designed to increase  competition in the domestic power  generation
industry  and  increase   access  to  electric   utilities'   transmission   and
distribution systems for independent power producers and electricity  consumers.
In particular, the state of California has restructured its electric industry by
providing for a phased-in  competitive power generation  industry,  with a power
pool and an independent system operator, and for direct access to generation for
all power  purchasers  outside the power exchange  under certain  circumstances.
Although  existing  QF  power  sales  contracts  are to be  honored  under  such
restructuring,  and all of our California  operating projects are QFs, until the
new system is fully  implemented,  it is impossible  to predict what impact,  if
any, it may have on the operations of those projects.

     We may be unable to obtain an adequate supply of natural gas in the future.
To date, our fuel acquisition  strategy has included various combinations of our
own gas reserves,  gas  prepayment  contracts and short-,  medium- and long-term
supply contracts.  In our gas supply arrangements,  we attempt to match the fuel
cost with the fuel component  included in the facility's power sales agreements,
in order to minimize a project's  exposure to fuel price risk.  We believe  that
there will be adequate  supplies of natural gas available at  reasonable  prices
for each of our facilities when current gas supply agreements  expire.  However,
gas  supplies may not be available  for the full term of the  facilities'  power
sales  agreements,  and gas prices  may  increase  significantly.  If gas is not
available, or if gas prices increase above the fuel component of the facilities'
power  sales  agreements,  there  could be a negative  impact on our  results of
operations.

     Competition  could adversely affect our  performance.  The power generation
industry is characterized by intense competition.  We encounter competition from
utilities,  industrial  companies  and other power  producers.  In recent years,
there  has been  increasing  competition  in an effort  to  obtain  power  sales
agreements.  This  competition  has  contributed  to a reduction in  electricity
prices. In addition,  many states have implemented or are considering regulatory
initiatives  designed to increase  competition in the domestic  power  industry.
This  competition  has put pressure on electric  utilities to lower their costs,
including the cost of purchased electricity.

     Our  international   investments  may  face  uncertainties.   We  have  one
investment  in  geothermal  steam  fields  located  in  Mexico  and  may  pursue
additional international  investments.  International investments are subject to
unique risks and  uncertainties  relating to the political,  social and economic
structures of the countries in which we invest.  Risks  specifically  related to
investments in non-United States projects may include:

*    risks of fluctuations in currency valuation,
*    currency inconvertibility,
*    expropriation and confiscatory taxation,
*    increased regulation, and
*    approval requirements and governmental policies limiting returns to foreign
     investors.

     We depend on our senior management. Our success is largely dependent on the
skills,  experience  and  efforts  of our  senior  management.  The  loss of the
services of one or more members of our senior  management  could have a negative
effect on our business, financial results and future growth.

     Seismic  disturbances could damage our project.  Areas where we operate and
are  developing  many of our  geothermal  and gas-fired  projects are subject to
frequent low-level seismic  disturbances.  More significant seismic disturbances
are possible.  Our existing power  generation  facilities are built to withstand
relatively  significant  levels  of  seismic  disturbances,  and we  believe  we
maintain adequate insurance protection.  However, earthquake, property damage or
business interruption  insurance may be inadequate to cover all potential losses
sustained in the event of serious seismic disturbances.  Additionally, insurance
may not continue to be available to us on commercially reasonable terms.

                                       27


     Our  results  are  subject to  quarterly  and  seasonal  fluctuations.  Our
quarterly  operating  results have fluctuated in the past and may continue to do
so in the future as a result of a number of factors, including:

*    the timing and size of acquisitions,
*    the completion of development projects, and
*    variations in levels of production.

     Additionally,  because we receive the majority of capacity  payments  under
some of our power sales agreements during the months of May through October, our
revenues and results of operations are, to some extent, seasonal.

     The price of our common stock is volatile.  The market price for our common
stock has been volatile in the past,  and several  factors could cause the price
to fluctuate substantially in the future. These factors include:

*    announcements of developments related to our business,
*    fluctuations in our results of operations,
*    sales of substantial amounts of our securities into the marketplace,
*    general conditions in our industry or the worldwide economy,
*    an outbreak of war or hostilities,
*    a  shortfall  in revenues or  earnings  compared  to  securities  analysts'
     expectations,
*    changes in analysts' recommendations or projections, and
*    announcements of new acquisitions or development projects by us.

     The market price of our common  stock may  fluctuate  significantly  in the
future,  and these  fluctuations  may be unrelated to our  performance.  General
market price declines or market  volatility in the future could adversely affect
the price of our common  stock,  and thus,  the current  market price may not be
indicative of future market prices.

     We could be adversely  affected if our  computer  systems are not Year 2000
compliant.  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.

     We are  coordinating  our efforts to address the impact of Year 2000 on our
business through a Year 2000 Project Team comprised of representatives from each
business unit and our 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 our technology.

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

*    Corporate applications, which include core business systems;
*    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 our Management  Information Systems department has the responsibility.  We
utilize PeopleSoft for our major core systems.  The PeopleSoft  applications 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 and other embedded systems.
Each business unit is  responsible  for the  inventory  and  remediation  of its
embedded


                                       28


systems. In addition, we are 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.

     An  Inventory  phase for  non-information  technology/embedded  systems was
completed  in October  1998.  The  Initial  Assessment  Phase was  completed  in
December 1998. We plan to complete  remediation of non-compliant  systems by the
fourth quarter of 1999. To date, all embedded  systems that have been identified
by Calpine can be upgraded or modified within our current schedule. The schedule
for  addressing  year 2000  issues  with  respect to mission  critical  embedded
systems is as follows:

PHASE                       STATUS            ESTIMATED COMPLETION DATE
- --------------------        ----------------  -------------------------
Inventory                   Complete          September 1998
Initial Assessment          Complete          November 1998
Detail Assessment           Complete          May 1999
Remediation                 Complete          November 1999
Contingency Planning        In-progress(90%)  November 1999

     Testing of embedded  systems is complex because some of the testing must be
completed during power plant scheduled  maintenance outages. Most of the testing
is already  completed in  cooperation  with  vendors and other power  companies.
Remainder  of the  testing is  scheduled  this year during  regularly  scheduled
maintenance outage periods. So far we have not found anything during the testing
and  remediation  which we think  will  hinder us from  achieving  our Year 2000
objective.

     End-User  Computing  Systems - Some of our  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.

     Our end-user  computing systems are being inventoried by each business unit
and evaluated and  remediated by the Company's MIS staff.  We expect to complete
this process by year-end 1999.

     Business  Partner  and Vendor  Systems - We have  contracts  with  business
partners and vendors who provide  products  and services to the Company.  We are
vigorously seeking to obtain Year 2000 assurances from these third parties. Year
2000 Project Team and appropriate  business units are jointly  undertaking  this
effort.  We have sent  letters and  accompanying  Year 2000 surveys to about 800
vendors and suppliers. We have received most of responses as of Sept 1999. These
responses  outline to varying  degrees the approach  vendors are  undertaking to
resolve Year 2000 issues  within their own systems.  Majority of our vendors and
suppliers  have  indicated  that they are ready for year 2000 or they are making
significant  progress and will be ready by the year-end.  Follow-up  letters are
being sent to all vendors to ascertain their latest status.

     Contingency Planning - Contingency and business  continuation  planning are
in various stages of development  for critical and  high-priority  systems.  Our
existing  disaster response plan and other contingency plans are scheduled to be
evaluated  and  will  be  adopted  for  use  in  case  of any  Year  2000related
disruption. We expect to complete our contingency planning by November 1999.

     Costs - The costs of expected  modifications are currently  estimated to be
approximately $1.7 million which will be charged to expense as incurred. For the
nine months  ended  September  30,  1999,  $401,000 has been charged to expense.
Approximately 9% of the estimated total cost has been incurred in 1998, 63% will
be incurred in 1999,  and the  remainder  will be incurred in 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.

                                       29


     Risks - We currently  expect to complete our Year 2000 efforts with respect
to critical systems by fall of 1999. This schedule and our cost estimates may be
affected by, among other things,  the  availability of Year 2000 personnel,  the
readiness of third  parties,  the timing for testing our embedded  systems,  the
availability of vendor  resources to complete  embedded  system  assessments and
produce  required  component  upgrades and our ability to implement  appropriate
contingency plans.

     We produce revenues by selling power we produce to customers.  We depend on
transmission  and  distribution  facilities  that  are  owned  and  operated  by
investor-owned  utilities to deliver power to the our  customers.  If either our
customers  or  the  providers  of  transmission  and   distribution   facilities
experience  significant  disruptions  as a result of the Year 2000 problem,  our
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 our future operations, financial
results or our financial condition.

Financial Market Risks

     From time to time,  we use interest  rate swap  agreements  to mitigate our
exposure to  interest  rate  fluctuations.  We do not use  derivative  financial
instruments for speculative or trading purposes.  The following table summarizes
the fair  market  value of our  existing  interest  rate swap  agreements  as of
September 30, 1999 (in thousands):


                                      Weighted

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


     Short-term  investments.  As of  September  30,  1999,  we have  short-term
investments of $45.7 million.  These  short-term  investments  consist of highly
liquid  investments  with  maturities  between  three and twelve  months.  These
investments  are  subject to  interest  rate risk and will  increase in value if
market interest rates increase. We have the ability to hold these investments to
maturity, and as a result, we would not expect the value of these investments to
be affected to any significant degree by the effect of a sudden change in market
interest  rates.  Declines in interest  rates over time will reduce our interest
income.

     Outstanding  debt. As of September 30, 1999, we have outstanding  long-term
debt of approximately  $1.7 billion  primarily made up of $1.6 billion of senior
notes and $115.2 million of construction  financing.  Our construction financing
has a floating  interest rate of 6.75% as of September 30, 1999. Our outstanding
long-term Senior Notes as of September 30, 1999 are as follows (in thousands):

     Gas price fluctuations.   We enter into derivative commodity instruments to
hedge our exposure to the impact of price  fluctuations  on gas purchases.  Such
instruments include regulated natural gas contracts and  over-the-counter  swaps
and basis hedges with major energy  derivative  product  specialists.  All hedge
transactions  are subject to our risk  management  policy  which does not permit
speculative  positions.  These  transactions  are  accounted for under the hedge
method of accounting.  Cash flows from derivative  instruments are recognized as
incurred through changes in working capital.

Impact  of Recent  Accounting  Pronouncements  -- In June  1999,  the  Financial
Accounting  Standards Board issued Statement of Financial  Accounting  Standards
("SFAS") No. 137, "Accounting for Derivative  Instruments and Hedging Activities
- - Deferral of the Effective Date of SFAS No. 133". The Statement amends SFAS No.
133 to defer its  effective  date to all fiscal  quarters  of all  fiscal  years
beginning  after June 15, 2000.  We have not yet analyzed the impact of adopting
SFAS No. 133 on the financial  statements  and have not determined the timing of
or method of the adoption of SFAS No. 133. However, the Statement could increase
the volatility of our earnings.

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 our 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  claimed that
Calpine Gordonsville,  Inc., Calpine Auburndale, Inc. and the Company tortuously
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 April 1999, the court granted Calpine Gordonsville
and Calpine Auburndale's motions to dismiss with prejudice, a decision which has
been  appealed by Indeck.  The Company is unable to predict the outcome 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  the  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 adverse effect on the Company's financial
