                      CALPINE CORPORATION AND SUBSIDIARIES
              Notes to Consolidated Condensed Financial Statements
                                  June 30, 2002
                                   (unaudited)

1.   Organization and Operation of the Company

     Calpine Corporation ("Calpine"),  a Delaware corporation,  and subsidiaries
(collectively, "the Company") is engaged in the generation of electricity in the
United  States,  Canada and the United  Kingdom.  The Company is involved in the
development, acquisition, ownership and operation of power generation facilities
and the sale of electricity and its by-product, thermal energy, primarily in the
form of steam.  The Company has  ownership  interests in and operates  gas-fired
power generation and cogeneration facilities,  gas fields, gathering systems and
gas  pipelines,   geothermal   steam  fields  and  geothermal  power  generation
facilities in the United States.  In Canada,  the Company owns power  facilities
and oil and gas operations.  In the United Kingdom, the Company owns a gas-fired
power  cogeneration  facility.  Each of the generation  facilities  produces and
markets  electricity  for sale to  utilities  and other third party  purchasers.
Thermal  energy  produced by the  gas-fired  power  cogeneration  facilities  is
primarily sold to industrial users. Gas produced and not physically delivered to
the Company's generating plants is sold to third parties.

2.   Summary of Significant Accounting Policies

     Basis  of  Interim  Presentation  --  The  accompanying  unaudited  interim
consolidated condensed financial statements of the Company have been prepared by
the Company pursuant to the rules and regulations of the Securities and Exchange
Commission.  In the opinion of management,  the consolidated condensed 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  in the  United  States  of  America  have been
condensed  or  omitted  from  these  statements   pursuant  to  such  rules  and
regulations  and,  accordingly,  these  financial  statements  should be read in
conjunction with the audited  consolidated  financial  statements of the Company
for the year ended December 31, 2001, included in the Company's Annual Report on
Form 10-K. The results for interim periods are not necessarily indicative of the
results for the entire year. The Company's historical amounts have been restated
to reflect  the  pooling-of-interests  transaction  completed  during the second
quarter of 2001 for the acquisition of Encal Energy Ltd. ("Encal").

     Use of Estimates in Preparation of Financial  Statements -- The preparation
of  financial  statements  in  conformity  with  generally  accepted  accounting
principles in the United States of America requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities,  and
disclosure of  contingent  assets and  liabilities  at the date of the financial
statements and the reported  amounts of revenue and expense during the reporting
period.  Actual results could differ from those estimates.  The most significant
estimates with regard to these financial  statements  relate to useful lives and
carrying  values  of  assets  (including  the  carrying  value  of  projects  in
development, construction and operation), provision for income taxes, fair value
calculations  of  derivative   instruments  and  depletion,   depreciation   and
impairment  of  natural  gas  and  petroleum  property  and  equipment.  See the
"Critical  Accounting  Policies"  subsection in the Management's  Discussion and
Analysis of  Financial  Condition  and Results of  Operations  in the  Company's
Annual Report on Form 10-K for the year ended  December 31, 2001,  for a further
discussion of the Company's significant estimates.

     Revenue  Recognition  -- The Company is  primarily  an electric  generation
company,  operating  a portfolio  of mostly  wholly  owned  plants but also some
plants in which its  ownership  interest is 50% or less and which are  accounted
for under  the  equity  method.  In  conjunction  with its  electric  generation
business, the Company also produces, as a by-product, thermal energy for sale to
customers,  principally  steam hosts at the  Company's  cogeneration  sites.  In
addition,  the Company acquires and produces natural gas for its own consumption
and sells the balance and oil produced to third parties.  To protect and enhance
the profit potential of its electric generation plants, the Company, through its
subsidiary,  Calpine Energy Services, L.P. ("CES"), enters into electric and gas
hedging, balancing, and optimization transactions, subject to market conditions,
and CES has also, from time to time,  entered into contracts  considered  energy
trading  contracts  under  Emerging  Issues Task Force  ("EITF") Issue No. 98-10
"Accounting  for  Contracts  Involved  in  Energy  Trading  and Risk  Management
Activities."  CES  executes  these  transactions  primarily  through  the use of
physical forward commodity purchases and sales and financial commodity swaps and
options. With respect to its physical forward contracts, CES generally acts as a
principal, takes title to the commodities,  and assumes the risks and rewards of
ownership.  Therefore,  in accordance  with Staff  Accounting  Bulletin No. 101,
"Revenue  Recognition  in  Financial  Statements"  and  EITF  Issue  No.  99-19,
"Reporting  Revenue Gross as a Principal Versus Net as an Agent," CES recognizes
revenue from settlement of its physical forward  contracts on a gross basis. CES
settles its financial swap and option  transactions  net and does not take title
to the  underlying  commodity.  Accordingly,  CES records  gains and losses from
settlement of financial swaps and options net in income. Managed risks typically
include commodity price risk associated with fuel purchases and power sales.


                                      -7-


     It is our policy not to engage in "roundtrip"  trades.  We have conducted a
detailed  analysis of our records looking for instances of transactions that may
have the  characteristics  of  "roundtrip"  trades  (i.e.,  trades with the same
counterparty  at the same time,  price and location) for the period from January
1, 2000 through June 30, 2002, and have  determined that while there were a very
small number of transactions  with such  characteristics,  there was no material
impact on our financial  statements from any such trades and none were conducted
for the purpose of increasing trading volume,  revenue,  or market prices or for
any other improper purpose.

     The Company,  through its wholly owned subsidiary,  Power Systems Mfg., LLC
("PSM"),  designs and  manufactures  certain spare parts for gas  turbines.  The
Company also generates small amounts of revenue by occasionally loaning funds to
power  projects,  by providing  operation and  maintenance  ("O&M")  services to
unconsolidated power projects,  and by performing  engineering services for data
centers and other facilities requiring highly reliable power. Further details of
the Company's revenue  recognition  policy for each type of revenue  transaction
are provided below:

     Electric Generation and Marketing Revenue -- This includes  electricity and
steam sales, mark-to-market gains and losses from electric power derivatives and
sales of purchased power.  Subject to market and other  conditions,  the Company
manages the revenue stream for its portfolio of electric generating  facilities.
The  Company  markets on a system  basis both power  generated  by its plants in
excess of amounts under direct contract between the plant and a third party, and
power purchased from third parties, through hedging, balancing, optimization and
trading transactions.  CES performs a market-based  allocation of total electric
generation  and marketing  revenue,  exclusive of  mark-to-market  activity,  to
electricity  and steam sales (based on  electricity  delivered by the  Company's
electric  generating  facilities  to serve CES  contracts)  and the  balance  is
allocated to sales of  purchased  power.  Sales of purchased  power also include
revenue from the  settlement of contracts that had been  previously  recorded in
results of  operations  as electric  power  derivative  mark-to-market  gains or
losses prior to realization.

     Oil and Gas  Production  and Marketing  Revenue -- This  includes  sales to
third  parties  of oil,  gas and  related  products  that  are  produced  by the
Company's  Calpine Natural Gas and Calpine Canada Natural Gas subsidiaries  and,
subject to market and other  conditions,  sales of  purchased  gas arising  from
hedging,  balancing,  optimization and trading transactions.  Sales of purchased
gas  also  include  revenue  from  the  settlement  of  contracts  that had been
previously   recorded  in  results  of  operations  as  natural  gas  derivative
mark-to-market  gains or  losses,  prior to  realization.  Oil and gas sales for
produced products are recognized pursuant to the sales method.

     Income from  Unconsolidated  Investments  in Power  Projects -- The Company
uses the equity  method to  recognize  as revenue  its pro rata share of the net
income or loss of the unconsolidated  investment until such time, if applicable,
that the Company's investment is reduced to zero, at which time equity income is
generally recognized only upon receipt of cash distributions from the investee.

     Other Revenue -- This  includes O&M contract  revenue,  interest  income on
loans to power  projects,  PSM revenue from sales to third parties,  engineering
revenue and miscellaneous revenue.

     Purchased  Power and Purchased  Gas Expense -- The cost of power  purchased
from third parties for hedging, balancing,  optimization and trading activities,
along with costs  from the  subsequent  settlement  of  contracts  that had been
previously  recorded  in results of  operations  as  electric  power  derivative
mark-to-market gains or losses, prior to realization,  are recorded as purchased
power expense, a component of electric generation and marketing expense.

     The Company records the cost of gas consumed in its power plants as cost of
oil and  natural  gas burned by power  plants,  while gas  purchased  from third
parties for hedging, balancing,  optimization and trading activities, along with
costs from the  subsequent  settlement  of  contracts  that had been  previously
recorded in results of operations as natural gas derivative mark-to-market gains
or losses,  prior to  realization,  are  recorded as purchased  gas  expense,  a
component of oil and gas production and marketing expense.

     Derivative  Instruments -- Financial  Accounting  Standards  Board ("FASB")
Statement of Financial  Accounting  Standards ("SFAS") No. 133,  "Accounting for
Derivative  Instruments  and  Hedging  Activities"  as amended by SFAS No.  137,
"Accounting for Derivative Instruments and Hedging Activities -- Deferral of the
Effective  Date of FASB  Statement No. 133 -- an Amendment of FASB Statement No.
133," and as further amended by SFAS No. 138, "Accounting for Certain Derivative
Instruments and Certain Hedging Activities -- an Amendment of FASB Statement No.
133," together with related guidance from the Derivatives  Implementation Group,
established  accounting and reporting  standards requiring that every derivative
instrument   (including  certain  derivative   instruments   embedded  in  other
contracts)  be  recorded in the  balance  sheet as either an asset or  liability
measured at its fair value unless exempted from derivative treatment as a normal
purchase and sale. The statement  requires that changes in the derivative's fair
value be recognized  currently in earnings  unless  specific  hedge criteria are
met, and requires that a company must formally document,  designate,  and assess
the effectiveness of transactions that receive hedge accounting.

                                      -8-


     SFAS No. 133 provides that the  effective  portion of the gain or loss on a
derivative   instrument  designated  and  qualifying  as  a  cash  flow  hedging
instrument be reported as a component of other comprehensive  income ("OCI") and
be  reclassified  into  earnings  in the same  period  during  which the  hedged
forecasted  transaction  affects  earnings.  The  remaining  gain or loss on the
derivative  instrument,  if any, must be recognized currently in earnings.  SFAS
No. 133 provides  that the changes in fair value of  derivatives  designated  as
fair value hedges and the corresponding  changes in the fair value of the hedged
risk  attributable  to a  recognized  asset,  liability,  or  unrecognized  firm
commitment  be  recorded  in  earnings.  If the fair  value  hedge is  perfectly
effective, such amounts recorded in earnings will be equal and offsetting.

     SFAS  No.  133  requires  that as of the  date  of  initial  adoption,  the
difference  between the fair value of  derivative  instruments  and the previous
carrying  amount of these  derivatives  be  recorded  in net  income or OCI,  as
appropriate,  as the cumulative effect of a change in accounting principle. Upon
adoption of SFAS No. 133  effective  January 1, 2001,  the Company  recorded the
cumulative effect of a change in accounting  principle of $1.0 million (net of a
$0.7  million tax  provision)  to net income and $39.8  million  (net of a $25.7
million tax provision) to OCI.

     New Accounting  Pronouncements -- In June 2001 the Company adopted SFAS No.
141,  "Business  Combinations,"  which  supersedes  Accounting  Principles Board
("APB") Opinion No. 16, "Business Combinations" and SFAS No. 38, "Accounting for
Preacquisition  Contingencies of Purchased Enterprises." SFAS No. 141 eliminated
the  pooling-of-interests  method of accounting  for business  combinations  and
modified the recognition of intangible assets and disclosure  requirements.  The
adoption  of SFAS  No.  141 did not  have a  material  effect  on the  Company's
consolidated financial statements.

     On January 1, 2002, the Company  adopted SFAS No. 142,  "Goodwill and Other
Intangible  Assets," which supersedes APB Opinion No. 17,  "Intangible  Assets."
See Note 4 for more information.

     In June 2001 the FASB issued SFAS No. 143, "Accounting for Asset Retirement
Obligations,"  which amends SFAS No. 19, "Financial  Accounting and Reporting by
Oil and Gas Producing  Companies." SFAS No. 143 addresses  financial  accounting
and  reporting  for  obligations  associated  with the  retirement  of  tangible
long-lived  assets  and the  associated  asset  retirement  costs.  SFAS No. 143
requires that the fair value of a liability for an asset  retirement  obligation
be recognized in the period in which it is incurred if a reasonable  estimate of
fair  value can be made.  SFAS No. 143 is  effective  for  financial  statements
issued for fiscal  years  beginning  after June 15,  2002.  The Company does not
believe  that SFAS No.  143 will  have a  material  impact  on its  consolidated
financial statements.

     On January 1, 2002, the Company  adopted SFAS No. 144,  "Accounting for the
Impairment or Disposal of Long-Lived  Assets,"  which  supersedes  SFAS No. 121,
"Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to
be Disposed Of," and the accounting and reporting  provisions of APB Opinion No.
30, "Reporting the Results of Operations -- Reporting the Effects of Disposal of
a Segment of a Business,  and Extraordinary,  Unusual and Infrequently Occurring
Events and  Transactions,"  for the  disposal  of a segment  of a  business  (as
previously  defined  in that APB  Opinion).  SFAS No. 144  establishes  a single
accounting  model,  based on the  framework  established  in SFAS No.  121,  for
long-lived  assets to be disposed of by sale. SFAS No. 144 also resolves several
significant  implementation  issues related to SFAS No. 121, such as eliminating
the  requirement  to  allocate  goodwill to  long-lived  assets to be tested for
impairment and  establishing  criteria to define  whether a long-lived  asset is
held for sale.  Adoption  of SFAS No. 144 has not had a  material  effect on the
Company's consolidated financial statements.

     In April 2002 the FASB issued SFAS No. 145,  "Rescission of FASB Statements
No.  4,  44,  and  64,  Amendment  of  FASB  Statement  No.  13,  and  Technical
Corrections." SFAS No. 145 rescinds SFAS No. 4, "Reporting Gains and Losses from
Extinguishment  of Debt"  and an  amendment  of that  statement,  SFAS  No.  64,
"Extinguishments of Debt Made to Satisfy Sinking-Fund Requirements" stating that
gains or losses from  extinguishment  of debt that fall  outside of the scope of
APB Opinion No. 30 should not be classified as extraordinary.  SFAS No. 145 also
amends SFAS No. 13,  "Accounting  for  Leases," to  eliminate  an  inconsistency
between the required accounting for sale-leaseback transactions and the required
accounting for certain lease  modifications  that have economic effects that are
similar to sale-leaseback transactions.  SFAS No. 145 also amends other existing
authoritative  pronouncements  to make various  technical  corrections,  clarify
meanings,  or  describe  their  applicability  under  changed  conditions.   The
provisions  related to the  rescission  of SFAS No. 4 shall be applied in fiscal
years beginning after May 15, 2002. The provisions  related to SFAS No. 13 shall
be effective for transactions occurring after May 15, 2002. All other provisions
shall be effective  for  financial  statements  issued on or after May 15, 2002,
with early adoption  encouraged.  The Company has not completed its analysis but
believes that SFAS No. 145 may have a material effect on the presentation of its
financial statements but no impact on net income.





                                      -9-


     In June 2002 the FASB issued SFAS No. 146, "Accounting for Costs Associated
with Exit or Disposal  Activities," which addresses accounting for restructuring
and  similar  costs.  SFAS No.  146  supersedes  previous  accounting  guidance,
principally  EITF Issue No. 94-3,  "Liability  Recognition for Certain  Employee
Termination  Benefits  and Other  Costs to Exit an Activity  (Including  Certain
Costs  Incurred in a  Restructuring)."  The Company will adopt the provisions of
SFAS No. 146 for  restructuring  activities  initiated  after December 31, 2002.
SFAS No. 146 requires that the liability  for costs  associated  with an exit or
disposal activity be recognized when the liability is incurred.  Under Issue No.
94-3, a liability  for an exit cost was  recognized at the date of commitment to
an exit plan. SFAS No. 146 also  establishes that the liability should initially
be measured and recorded at fair value. Accordingly, SFAS No. 146 may affect the
timing  of  recognizing  future  restructuring  costs  as  well  as the  amounts
recognized.  The Company does not believe that SFAS No. 146 will have a material
effect on its consolidated financial statements.

     In June  2002 the EITF  reached  a  consensus  on two of the  three  issues
considered  in EITF 02-03,  "Recognition  and  Reporting  of Gains and Losses on
Energy Trading Contracts under EITF Issues No. 98-10,  `Accounting for Contracts
Involved  in Energy  Trading  and Risk  Management  Activities'  and No.  00-17,
`Measuring  the Fair Value of  Energy-Related  Contracts  in applying  Issue No.
98-10.'"  The  issues  upon  which the EITF  reached a  consensus  required  net
presentation of energy trading contracts in a company's financial statements and
required that companies make certain disclosures  regarding their energy trading
contracts.   The  net  presentation   requirement  is  effective  for  financial
statements  issued for periods  ending after July 15, 2002,  and the  disclosure
requirements  are  effective for  financial  statements  issued for fiscal years
ending  after July 15,  2002.  The  Company is still  assessing  the  impacts of
adopting  this  standard on its financial  statements,  but believes  that, at a
minimum,  all energy trading  contracts will be reported net, rather than gross,
upon  adoption  of this  standard.  The  standard is expected to have a material
impact on total revenues and expenses, but no impact on net income.

     Reclassifications  -- Prior period  amounts in the  consolidated  condensed

     Construction  in progress is  primarily  attributable  to  gas-fired  power
projects under construction  including prepayments on gas turbine generators and
other long lead-time items of equipment for certain development projects not yet
in  construction.   Upon  commencement  of  plant  operation,  these  costs  are
transferred to the applicable property category, generally buildings,  machinery
and equipment.  In March 2002 the Company  announced a change in its turbine and
construction program that will slow the growth in the Company's  construction in
progress. See Note 13 for a discussion of the turbine order cancellations during
the first quarter.

     During the second quarter of 2002, the Company  reclassified $203.7 million
of turbine costs from  construction in progress to other assets, as the turbines
will not be used for the Company's current power plant development  program. The
Company recorded a $14.2 million charge to project development expense to effect
a reduction  in the  carrying  value of such  turbines.  The  Company  currently
anticipates  that some of the turbines  will be used for future power plants and
others  may be sold to third  parties.  The  Company is now in  negotiations  to
cancel or restructure  the contracts for up to 89 units.  The Company expects to
complete these negotiations in the fourth quarter of 2002. The Company may also,
subject  to market  conditions,  take  steps to  further  adjust or  restructure
turbine orders,  including canceling additional turbine orders,  consistent with
the Company's power plant construction and development programs.


                                      -10-


     Capitalized  Interest  --  The  Company  capitalizes  interest  on  capital
invested  in  projects  during  the  advanced  stages  of  development  and  the
construction period in accordance with SFAS No. 34,  "Capitalization of Interest
Cost," as amended by SFAS No. 58,  "Capitalization of Interest Cost in Financial
Statements  That  Include  Investments  Accounted  for by the Equity  Method (an
Amendment of FASB  Statement No. 34)." The Company's  qualifying  assets include
construction  in progress,  certain oil and gas  properties  under  development,
construction costs related to unconsolidated investments in power projects under
construction,  and advanced  stage  development  costs.  During the three months
ended June 30,  2002 and 2001,  the total  amount of  interest  capitalized  was
$171.0 million and $115.6  million,  including  $37.0 million and $31.2 million,
respectively,  of interest incurred on funds borrowed for specific  construction
projects  and  $134.0  million  and $84.4  million,  respectively,  of  interest
incurred on general corporate funds used for construction. During the six months
ended June 30,  2002 and 2001,  the total  amount of  interest  capitalized  was
$334.1 million and $219.6  million,  including  $72.1 million and $65.9 million,
respectively,  of interest incurred on funds borrowed for specific  construction
projects  and $262.0  million  and $153.7  million,  respectively,  of  interest
incurred on general corporate funds used for construction.  Upon commencement of
plant operation,  capitalized  interest, as a component of the total cost of the
plant, is amortized over the estimated useful life of the plant. The increase in
the amount of interest  capitalized during 2002,  compared to 2001, reflects the
significant increase in the Company's power plant construction program. However,
the Company  expects that the amount of interest  capitalized  will  decrease in
future periods as the power plants in construction are completed and as a result
of the current suspension of certain of the Company's development projects.

     In  accordance  with  SFAS  No.  34,  the  Company  determines  which  debt
instruments  best  represent  a  reasonable  measure  of the  cost of  financing
construction assets in terms of interest cost incurred that otherwise could have
been avoided.  These debt instruments and associated  interest cost are included
in the calculation of the weighted  average  interest rate used for capitalizing
interest on general  funds.  The primary debt  instruments  included in the rate
calculation are the Company's senior notes, the Company's term loan facility and
the Company's revolving credit facilities.

4.   Goodwill and Other Intangible Assets

     On January 1, 2002, the Company  adopted SFAS No. 142,  "Goodwill and Other
Intangible Assets," which requires that all intangible assets with finite useful
lives be amortized and that goodwill and intangible assets with indefinite lives
not be  amortized,  but rather  tested upon  adoption and at least  annually for
impairment.  The  Company  was  required  to  complete  the  initial  step  of a
transitional  impairment  test within six months of adoption of SFAS No. 142 and
to complete the final step of the transitional impairment test by the end of the
fiscal year. Any future  impairment losses will be reflected in operating income
or loss in the consolidated statements of operations.  The Company completed the
transitional  goodwill  impairment test as required and determined that the fair
value of the  reporting  units  holding  goodwill  exceeded  their net  carrying
values. Therefore, the Company did not record any impairment expense.

     In accordance with the standard,  the Company discontinued the amortization
of its recorded  goodwill as of January 1, 2002, and identified  reporting units
based on its current  segment  reporting  structure  and  allocated all recorded
goodwill,  as well as other assets and  liabilities,  to the reporting  units. A
reconciliation  of previously  reported net income and earnings per share to the
amounts  adjusted for the exclusion of goodwill  amortization  is provided below
(in thousands, except per share amounts):

due prior to the earliest of the equipment  site delivery date  specified in the
agreement,  the  Company's  requested  date of turbine site delivery or June 25,
2003.  At March 31,  2002 and June 30,  2002,  there were $0 and $47.4  million,
respectively, in borrowings outstanding under this agreement.

     On April 30,  2002,  the  Company  completed  a  registered  offering of 66
million  shares of its common stock at $11.50 per share.  The proceeds from this
offering, after underwriting fees, were $734.3 million.

     On April 30, 2002, the Company  repurchased the remaining $685.5 million in
aggregate  principal amount of its Zero Coupon  Convertible  Debentures due 2021
("Zero Coupons") at par pursuant to a scheduled put provided for by the terms of
the Zero Coupons.

     On May 14,  2002,  the  Company's  subsidiary,  Calpine  California  Energy
Finance,  LLC,  entered into an amended and restated  credit  agreement with ING
Capital LLC for the funding of 9 California peaker  facilities,  of which $100.0
million  was  drawn  on May 24,  2002.  The  total  $100.0  million  funding  is
classified as current  project  financing,  of which $50.0 million was repaid on
August 7, 2002,  and $50.0 million will be payable on September  30, 2002.  This
peaker  funding is part of the  Company's  expected  long-term  financing of its
California peaker facilities which is anticipated to be $500.0 million.

     On May 31, 2002, the Company  increased its two-year secured bank term loan
to $1.0  billion  from  $600.0  million,  and  reduced  the size of its  secured
corporate revolving credit facilities to $1.0 billion from $1.4 billion. At June
30, 2002, the Company has $1.0 billion in funded  borrowings  outstanding  under
the term loan  facility,  and $75.0  million  in funded  borrowings  and  $723.2
million outstanding in letters of credit under the revolving credit facility.

     In 2003 and 2004, $981.4 million and $2,452.7 million, respectively,  under
the Company's secured revolving  construction  financing facilities will mature,
requiring the Company to refinance this indebtedness.

7.   DePere Transaction

     On June  28,  2002,  the  Company  executed  a  definitive  agreement  with
Wisconsin Public Service for the sale of its 180-megawatt  DePere Energy Center.
This  agreement  is subject  to certain  conditions,  including  the  receipt of
regulatory  approval by the State of Wisconsin,  which is expected to be decided
in  September  2002.  If the  agreement is approved by  regulatory  authorities,
Wisconsin  Public  Service would pay the Company  $120.4  million for the DePere
facility and the existing power purchase agreement would be terminated.

8.   Derivative Instruments

Commodity Derivative Instruments

     As an  independent  power  producer  primarily  focused  on  generation  of
electricity using gas-fired  turbines,  the Company's natural physical commodity
position is "short" fuel (i.e.,  natural gas  consumer)  and "long" power (i.e.,
electricity  seller).  To manage forward exposure to price  fluctuation in these
and (to a lesser extent) other  commodities,  the Company enters into derivative
commodity  instruments.  The Company enters into commodity financial instruments
to convert  floating or indexed  electricity and gas (and to a lesser extent oil
and refined product) prices to fixed prices in order to lessen its vulnerability
to reductions in electric prices for the electricity it generates, to reductions
in gas prices for the gas it  produces,  and to  increases in gas prices for the
fuel it consumes in its power plants.  The Company seeks to "self-hedge" its gas
consumption  exposure to an extent  with its own gas  production  position.  Any
hedging,  balancing,  or optimization activities that the Company engages in are
directly  related  to the  Company's  asset-based  business  model of owning and
operating  gas-fired  electric  power  plants and are  designed  to protect  the
Company's "spark spread" (the difference between the Company's fuel cost and the
revenue it receives for its electric  generation).  The Company hedges exposures
that arise from the ownership and operation of power plants and related sales of
electricity and purchases of natural gas, and the Company  utilizes  derivatives
to optimize the returns the Company is able to achieve from these assets for the
Company's shareholders. From time to time the Company has entered into contracts
considered  energy trading  contracts under EITF Issue No. 98-10.  However,  the
Company's  traders  have low capital at risk and value at risk limits for energy
trading, and its risk management policy limits, at any given time, its net sales
of power to its  generation  capacity and limits its net purchases of gas to its
fuel consumption requirements on a total portfolio basis. This model is markedly
different from that of companies that engage in  significant  commodity  trading
operations  that  are  unrelated  to  underlying  physical  assets.   Derivative
commodity  instruments are accounted for under the  requirements of SFAS No. 133
and EITF Issue No.  98-10.

     The Company also  routinely  enters into physical  commodity  contracts for
sales of its generated  electricity  and sales of its natural gas  production to
ensure favorable utilization of generation and production assets. Such contracts
often  meet  the  criteria  of SFAS No.  133 as  derivatives  but are  generally
eligible for the normal  purchases and sales  exception.  Some of those that are
not  deemed  normal  purchases  and  sales  can be  designated  as hedges of the
underlying consumption of gas or production of electricity.

                                      -13-


     In 2001  the FASB  cleared  SFAS  No.  133  Implementation  Issue  No.  C16
"Applying  the Normal  Purchases  and Normal Sales  Exception to Contracts  That
Combine a  Forward  Contract  and a  Purchased  Option  Contract"  ("C16").  The
guidance in C16  applies to fuel supply  contracts  that  require  delivery of a
contractual  minimum  quantity  of fuel at a fixed price and have an option that
permits  the  holder to take  specified  additional  amounts of fuel at the same
fixed price at various times. Under C16, the volumetric  optionality provided by
such  contracts is considered a purchased  option that  disqualifies  the entire
derivative  fuel supply  contract from being  eligible to qualify for the normal
purchases  and normal  sales  exception  in SFAS No. 133. On April 1, 2002,  the
Company adopted C16. At June 30, 2002, the Company had no fuel supply  contracts
to which C16 applies.  However, one of the Company's equity method investees has
fuel supply  contracts  subject to C16. The equity  investee also adopted C16 on
April 1, 2002. The contracts  qualified as highly effective hedges of the equity
method  investee's  forecasted  purchase  of gas.  Accordingly,  the Company has
recorded $7.8 million net of tax as a cumulative  effect of change in accounting
principle  to other  comprehensive  income  for its share of the  equity  method
investee's other comprehensive income from accounting change.

Interest Rate and Currency Derivative Instruments

     The Company also enters into various interest rate swap agreements to hedge
against changes in floating  interest rates on certain of its project  financing
facilities. The interest rate swap agreements effectively convert floating rates
into fixed rates so that the Company can predict with greater assurance what its
future  interest costs will be and protect itself against  increases in floating
rates.

     In conjunction with its capital markets activities, the Company enters into
various  forward  interest  rate  agreements  to  hedge  against  interest  rate
fluctuations  that may occur after the  Company  has decided to issue  long-term
fixed rate debt but before the debt is actually  issued.  The  forward  interest
rate  agreements  effectively  prevent the interest rates on anticipated  future
long-term debt from increasing  beyond a certain level,  allowing the Company to
predict  with greater  assurance  what its future  interest  costs on fixed rate
long-term debt will be.

     The Company enters into various  foreign  currency swap agreements to hedge
against changes in exchange rates on certain of its senior notes  denominated in
currencies  other than the U.S. dollar.  The foreign currency swaps  effectively
convert  floating  exchange  rates into fixed exchange rates so that the Company
can  predict  with  greater  assurance  what its U.S.  dollar  cost  will be for
purchasing  foreign currencies to satisfy the interest and principal payments on
these senior notes.

     At any  point in time,  it is highly  unlikely  that  total net  derivative
assets and liabilities will equal  accumulated OCI, net of tax from derivatives,
for three primary reasons:

     o    Tax effect of OCI -- When the values and subsequent  changes in values
          of derivatives that qualify as effective hedges are recorded into OCI,
          they are initially offset by a derivative asset or liability.  Once in
          OCI,  however,  these values are tax  effected  against a deferred tax
          liability,  thereby  creating  an  imbalance  between  net OCI and net
          derivative assets and liabilities.





                                      -14-


     o    Derivatives   not   designated   as  cash   flow   hedges   and  hedge
          ineffectiveness  -- Only  derivatives  that qualify as effective  cash
          flow  hedges  will  have  an  offsetting   amount   recorded  in  OCI.
          Derivatives  not  designated  as cash flow hedges and the  ineffective
          portion of derivatives designated as cash flow hedges will be recorded
          into  earnings  instead of OCI,  creating  a  difference  between  net
          derivative assets and liabilities and pre-tax OCI from derivatives.

     o    Termination  of  effective  cash  flow  hedges  prior to  maturity  --
          Following  the  termination  of  a  cash  flow  hedge  and  subsequent
          settlement with a counterparty,  the derivative  asset or liability is
          liquidated  and removed  from the books.  At this  point,  no asset or
          liability  exists on the books for the hedge  instrument but a balance
          remains  in  OCI,  which  is not  recognized  in  earnings  until  the
          forecasted  transactions occur. As a result, there will be a temporary
          difference  between OCI and derivative  assets and  liabilities on the
          books until the remaining OCI balance is recognized in earnings.

     The asset and  liability  balances for the Company's  commodity  derivative
instruments  represent the net totals after  offsetting  certain  assets against
certain   liabilities  under  the  criteria  of  FASB   Interpretation  No.  39,
"Offsetting of Amounts Related to Certain  Contracts (an  Interpretation  of APB
Opinion No. 10 and FASB  Statement No. 105)" ("FIN 39").  For a given  contract,
FIN 39 will allow the offsetting of assets  against  liabilities so long as four
criteria  are met:  (1) each of the two parties  under  contract  owes the other
determinable  amounts;  (2) the party  reporting under the offset method has the
right to set off the amount it owes  against  the amount owed to it by the other
party;  (3) the party  reporting under the offset method intends to exercise its
right to set off; and; (4) the right of set-off is enforceable by law. The table
below  reflects  both  the  amounts  (in  thousands)   recorded  as  assets  and
liabilities by the Company and the amounts that would have been recorded had the
Company's commodity derivative instrument contracts not qualified for offsetting

     For the three and six months  ended June 30, 2002 and 2001,  the  Company's
realized commodity cash flow hedge activity  contributed $36.0 million and $86.8
million,  respectively,  and $4.8 million and $21.8  million,  respectively,  to
pre-tax earnings based on the reclassification  adjustment from OCI to earnings.
For the  three  and six  months  ended  June 30,  2002 and  2001,  power  hedges
contributed $75.3 million and $161.8 million, respectively, and $3.1 million and
$(6.2) million,  respectively, to pre-tax earnings. For the three and six months
ended  June 30,  2002 and 2001,  gas and crude oil  hedges  contributed  $(39.3)
million and $(75.0) million,  respectively,  and $1.7 million and $28.0 million,
respectively,  to pre-tax earnings.  For the three and six months ended June 30,
2002,  interest  rate hedges  contributed  $(2.6)  million  and $(4.6)  million,
respectively,  to pre-tax earnings.  For the three and six months ended June 30,
2002,   currency   hedges   contributed   $(2.8)  million  and  $(2.8)  million,
respectively,  to pre-tax earnings.  For the three and six months ended June 30,
2001,  interest  rate hedges and  currency  hedges did not impact the  Company's
pre-tax earnings.

     As of June 30, 2002,  the maximum length of time over which the Company was
hedging its  exposure  to the  variability  in future cash flows for  forecasted
transactions  was 6, 6 1/2, and 12 years,  for commodity,  foreign  currency and
interest rate derivative instruments,  respectively.  The Company estimates that
pre-tax gains of $13.8 million would be reclassified  from  accumulated OCI into
earnings   during  the  twelve  months  ended  June  30,  2003,  as  the  hedged
transactions  affect earnings assuming  constant gas and power prices,  interest
rates,  and exchange rates over time;  however,  the actual amounts that will be
reclassified will likely vary based on the probability that gas and power prices
as well as interest rates and exchange rates will, in fact,  change.  Therefore,
management  is unable to predict  what the actual  reclassification  from OCI to
earnings (positive or negative) will be for the next twelve months.

Enron

     During 2001 the Company, primarily through its CES subsidiary, transacted a
significant volume of business with units of Enron Corp. ("Enron"), mainly Enron
Power Marketing, Inc. ("EPMI") and Enron North America Corp. ("ENA"). ENA is the
parent  corporation of EPMI. Enron is the direct parent corporation of ENA. Most
of these  transactions  were  contracts for sales and purchases of power and gas
for  hedging  purposes,  the  terms of  which  extended  out as far as 2009.  On
December 2, 2001,  Enron Corp. and certain of its  subsidiaries,  including EPMI
and ENA, filed voluntary  petitions for Chapter 11 reorganization  with the U.S.
Bankruptcy Court for the Southern District of New York.

     The Company has conducted no business  with EPMI or ENA since  December 31,
2001. The following table sets forth information regarding the Company's settled
physical  transactions and non-hedging  mark-to-market  gains with Enron for the
three and six months ended June 30, 2001, (in thousands of dollars and thousands
of MWh's, in the case of electricity transactions,  and thousands of MMBtu's, in
the case of oil and gas transactions):

     The Company has terminated  all of its open forward  positions with ENA and
EPMI,  and will  settle  with ENA and EPMI based on the value of the  terminated
contracts at the  termination or replacement  date, as applicable.  Accordingly,
all net amounts  associated with terminated ENA and EPMI forward  contracts have
been included within the Company's  accounts  payable.  During 2001 and prior to
the  termination  of its  forward  contracts  with ENA and EPMI,  certain of the
Company's  ENA and EPMI  contracts  had been  designated  as cash  flow  hedges.
Accordingly,  prior to termination of these positions,  balances had accumulated
in OCI. As of June 30, 2002, the Company had remaining unrealized pre-tax losses
of $183.4  million on derivatives  previously  designated as effective cash flow
hedges.  These  amounts will be  recognized  in future  earnings as the original
hedged forecasted transactions occur.

     The sales to and purchases from various Enron  subsidiaries were mostly for
hedging, balancing, optimization and trading transactions, and in most cases the
purchases and sales are not related and should not be netted to try to gauge the
profitability of transactions with Enron subsidiaries.

     On November  14, 2001,  CES,  ENA and EPMI  entered into a Master  Netting,
Setoff and Security Agreement (the "Netting  Agreement").  The Netting Agreement
permits CES, on the one hand,  and ENA and EPMI,  on the other hand,  to set off
amounts owed to each other under an ISDA Master  Agreement  between CES and ENA,
an Enfolio Master Firm Purchase/Sale  Agreement between CES and ENA and a Master
Energy Purchase/Sale  Agreement between CES and EPMI (in each case, after giving
effect to the netting provisions  contained in each of these agreements).  Based
on legal analysis of the Netting  Agreement,  the Company believes it has no net
collection exposure to Enron.

     After netting the receivables  from and payables to ENA and EPMI,  based on
certain assumptions, the Company has calculated an existing or future obligation
to Enron of  approximately  $143.5 million as of June 30, 2002, which obligation
the Company expects will be offset by CES' losses, damages,  attorneys' fees and
other expenses  arising from the default by Enron,  and which amount is included
in the Company's accounts payable balance at June 30, 2002.

Nevada Power and Sierra Pacific Power Company

     During  the first  quarter  of 2002,  two  subsidiaries  of Sierra  Pacific
Resources Company, Nevada Power Company ("NPC") and Sierra Pacific Power Company
("SPPC"),  received credit  downgrades to  sub-investment  grades from the major
credit  rating  agencies.  Additionally,  NPC  acknowledged  liquidity  problems
created  when the  Public  Utilities  Commission  of  Nevada  disallowed  a rate
adjustment  requested by NPC to cover the increased  cost of buying power during
the 2001  energy  crisis.  NPC has  requested  that its power  suppliers  extend
payment terms to help it overcome its short-term liquidity problems.  During the
second  quarter  of 2002,  NPC  indicated  to its  power  suppliers  that it was
experiencing  cash flow  difficulties.  In June and July 2002 NPC  underpaid the
Company by  approximately  $4.2 million,  and the Company  expects that NPC will
underpay the Company by  approximately  an additional  $18.4 million this summer
and early fall,  with  repayments  of deferred  amounts  beginning at some point
thereafter once NPC's cash flow stabilizes.  In consideration of the uncertainty
surrounding NPC's ability to make timely payments,  the Company is maintaining a
bad debt reserve of approximately  $2.7 million against NPC  receivables,  which
will be closely  monitored.  In  addition,  NPC and SPPC filed with the  Federal
Energy Regulatory Commission ("FERC") under Section 206 of the Federal Power Act
- - see Note 13 for further discussion.


                                      -19-


     As  of  June  30,  2002,  the  Company  had  net  collection  exposures  of
approximately  $34.8 million and $20.2 million with NPC and SPPC,  respectively.
However,  SPPC is paying the Company currently.  The Company's exposures include
open forward  power  contracts  that are reported at fair value on the Company's
balance sheet as well as receivable and payable balances relating to prior power
deliveries.  Management  is continuing to monitor the exposure and its effect on
the Company's financial condition. The table below details the components of the
Company's  exposure  position at June 30, 2002 (in  millions  of  dollars).  The
positive net positions  represent  realization  exposure  while the negative net
positions represent the Company's existing or potential obligations.

PSM License Receivable

     In December  2001 PSM and a Dutch power  services  company  entered  into a
perpetual world-wide license agreement for certain PSM proprietary  reverse-flow
venturi  technology.  The license fee, while earned upfront, is payable over the
period from January 2002 through March 2004. The Company  recognized the license
fee of $11  million  (less  imputed  interest  on the  receivable)  as income in
December 2001. As of the date of this filing, the Company has a receivable of $7
million,  with no payments  currently past due. The indirect parent of the Dutch
company, a German holding company,  filed for insolvency in Germany in July 2002
and the  direct  parent  of the  Dutch  company  is  expected  to also  file for
insolvency.  However,  the Dutch company has assured the Company that it has not
and  currently  does not expect to file for  insolvency  in the near  term.  The
Company has been  further  assured in a letter from the German  holding  company
dated July 11,  2002,  that the Dutch  company  expects to continue  the license
arrangement  and to meet its  obligations  thereunder.  Based  on the  Company's
evaluation  of these and other  factors,  a loss does not seem  probable at this
time. Accordingly, the Company has not established a reserve against the related
receivable but will continue to closely monitor the situation.

Credit Evaluations

     The  Company's  treasury  department  includes  a credit  group  focused on
monitoring  and managing  counterparty  risk.  The credit group monitors the net
exposure with each counterparty on a daily basis. The analysis is performed on a
mark-to-market  basis using the forward  curves  analyzed by the Company's  Risk
Controls group. The net exposure is compared against a counterparty  credit risk
threshold  which is  determined  based  on the  counterparty's  credit  ratings,
evaluation of the financial  statements and bond values.  The credit  department
monitors these thresholds to determine the need for additional  collateral or an
adjustment to activity with the counterparty.

11.  Earnings (Loss) Per Share

     Basic earnings (loss) per common share were computed by dividing net income
(loss) by the  weighted  average  number of common  shares  outstanding  for the
period. The dilutive effect of the potential exercise of outstanding  options to
purchase  shares of common stock is calculated  using the treasury stock method.
The dilutive effect of the assumed conversion of certain convertible  securities
into  the  Company's  common  stock  is  based  on  the  dilutive  common  share
equivalents and the after tax interest expense and distribution  expense avoided
upon conversion. The reconciliation of basic earnings (loss) per common share to
diluted earnings (loss) per share is shown in the following table (in thousands,
except per share data).

     For the three and six months  ended June 30, 2002 and for the three and six
months ended June 30, 2001, respectively,  the effect of 38,237, 145,819, 25,886

mandatorily  redeemable  convertible  preferred securities of subsidiary trusts,
Zero Coupons and  Convertible  Senior  Notes Due 2006,  were not included in the
computation of diluted shares outstanding because such inclusion would have been
antidilutive.

12.  Stock Compensation

     The Company accounts for qualified stock compensation under APB Opinion No.
25,  "Accounting  for Stock Issued to  Employees."  Had  compensation  cost been
determined  consistent  with the  methodology of SFAS No. 123,  "Accounting  for
Stock-Based  Compensation,"  which  provides  for the  accounting  of options as
compensation  expense,  the Company's net income (loss) and earnings  (loss) per
share would have been changed to the following pro forma amounts (in  thousands,
except per share amounts):

volatility of 97% for the three and six months ended June 30, 2002,  and 64% for
the three and six months ended June 30, 2001,  risk-free interest rates of 4.86%
for the three and six months  ended June 30,  2002,  and 5.42% for the three and

13.  Commitments and Contingencies

     Capital  Expenditures  -- On March 12,  2002,  the Company  announced a new
turbine  program  that  reduces   previously   forecasted  capital  spending  by
approximately  $1.2  billion  in 2002 and $1.8  billion  in 2003.  The  revision
includes  adjusted timing of turbine delivery and related payment  schedules and
also turbine order cancellations. As a result of the turbine order cancellations
and the cancellation of certain other equipment,  the Company recorded a pre-tax
charge of $168.5  million  in the first  quarter  of 2002,  based  primarily  on
forfeited  prepayments  to date  and an  immaterial  cash  payment  pursuant  to
contract terms.

     Litigation--

     Securities  Derivative Lawsuit. On December 17, 2001, a shareholder filed a
derivative lawsuit on behalf of the Company against its directors and one of its
senior officers.  This lawsuit is captioned  Johnson v. Cartwright,  et al. (No.
CV803872),  and is pending in the California Superior Court, Santa Clara County.
The  Company  is a nominal  defendant  in this  lawsuit,  which  alleges  claims
relating to purportedly  misleading statements about the Company and stock sales
by certain of the director defendants and the officer defendant. The Company has
filed a demurrer  asking the court to dismiss the  complaint  on the ground that
the  shareholder  plaintiff  lacks  standing  to pursue  claims on behalf of the
Company.  The individual  defendants  have filed a demurrer  asking the court to
dismiss the  complaint  on the ground that it fails to state any claims  against
them.  The Company  considers  this  lawsuit to be without  merit and intends to
vigorously defend against it.

     Securities Class Action Lawsuits.  Fourteen  shareholder lawsuits have been
filed  against  the Company  and  certain of its  officers in the United  States
District Court, Northern District of California.  The actions captioned Weisz v.
Calpine Corp., et al., filed March 11, 2002, and Labyrinth Technologies, Inc. v.
Calpine  Corp.,  et al.,  filed March 28, 2002,  are purported  class actions on
behalf of purchasers  of Calpine stock between March 15, 2001,  and December 13,
2001.  Gustaferro v. Calpine Corp.,  filed April 18, 2002, is a purported  class
action on behalf of purchasers of Calpine  stock between  February 6, 2001,  and



                                      -22-


December 13, 2001.  The eleven other actions,  captioned  Local 144 Nursing Home
Pension Fund v. Calpine Corp., Lukowski v. Calpine Corp., Hart v. Calpine Corp.,
Atchison v. Calpine Corp., Laborers Local 1298 v. Calpine Corp., Bell v. Calpine
Corp.,  Nowicki v. Calpine Corp.,  Pallotta v. Calpine Corp., Knepell v. Calpine
Corp.,  Staub v. Calpine  Corp.,  and Rose v. Calpine  Corp.  were filed between
March 18, 2002,  and April 23, 2002.  The complaints in these eleven actions are
virtually  identical--they  were filed by three law firms,  in conjunction  with
other law firms as co-counsel.  All eleven  lawsuits are purported class actions
on behalf of purchasers of the Company's securities between January 5, 2001, and
December 13, 2001.

     The complaints in these fourteen actions allege that,  during the purported
class periods,  certain senior  Calpine  executives  issued false and misleading
statements  about the  Company's  financial  condition  in violation of Sections
10(b) and 20(1) of the  Securities  Exchange Act of 1934, as well as Rule 10b-5.
These actions seek an unspecified amount of damages,  in addition to other forms
of relief.  The  Company  expects  that these  actions,  as well as any  related
actions that may be filed in the future,  will be consolidated by the court into
a single securities class action.

     In addition,  a fifteenth  securities class action, Ser v. Calpine, et al.,
was filed on May 13,  2002.  The  underlying  allegations  in the Ser action are
substantially the same to those in the  above-referenced  actions.  However, the
Ser  action is  brought  on behalf of a  purported  class of  purchasers  of the
Company's  8.5% Senior  Notes due  February  15, 2011  ("2011  Notes"),  and the
alleged  class period is October 15, 2001,  through  December 13, 2001.  The Ser
complaint alleges that, in violation of Sections 11 and 15 of the Securities Act
of 1933,  the Prospectus  Supplement  dated October 11, 2001, for the 2011 Notes
contained  false and  misleading  statements  regarding the Company's  financial
condition. This action names the Company, certain of its officers and directors,
and the  underwriters  of the 2011 Notes  offering as  defendants,  and seeks an
unspecified amount of damages, in addition to other forms of relief. The Company
expects that this action will either be consolidated  with the  above-referenced
actions  or will  proceed  as a parallel  related  action  before the same judge
presiding over the other actions.

     The Company  considers  the  allegations  against  Calpine in each of these
lawsuits to be without merit, and intends to defend vigorously against them.

     California  Business & Professions Code Section 17200 Cases. The lead case,
T&E Pastorino Nursery v. Duke Energy Trading and Marketing,  L.L.C., et al., was
served on May 2, 2002,  by T&E  Pastorino  Nursery,  on behalf of itself and all
others similarly situated.  This purported class action complaint against twenty
energy  traders and energy  companies  including  CES,  alleges that  defendants
exercised  market  power and  manipulated  prices  in  violation  of  California
Business & Professions Code Section 17200 et seq., and seeks injunctive  relief,
restitution and attorneys' fees.

     The  Company  also has been  named in five  other  similar  complaints  for
violations of Section 17200 captioned  Bronco Don Holdings,  LLP. v. Duke Energy
Marketing and Trading, et al.; Century Theatres, Inc. v. Allegheny Energy Supply
Company,  LLC; RDJ Farms,  Inc. v.  Allegheny  Energy Supply  Company,  LLC; J&M
Karsant  Family Limited  Partnership v. Duke Energy Trading and Marketing,  LLC;
and Leo's Day and Night Pharmacy v. Duke Energy Trading and Marketing,  LLC. All
six of these cases have been removed in a  multidistrict  litigation  proceeding
from the various  state  courts in which they were  originally  filed to federal
court, where a motion is now pending to transfer and consolidate these cases for
pretrial  proceedings  with other  cases in which the  Company is not named as a
defendant. In addition,  plaintiffs in the T&E Pastorino Nursery case have filed
a motion to remand that matter to California state court.

     The Company  considers  the  allegations  against  Calpine in each of these
lawsuits to be without merit, and intends to vigorously defend against them.

     California  Department of Water Resources Case. On May 1, 2002,  California
State  Senator  Tom  McClintock  and others  filed a  complaint  against  Vikram
Budhraja, a consultant to the California  Department of Water Resources ("DWR"),
DWR itself,  and more than twenty-nine energy providers and other interested
parties,  including the Company.  The complaint alleges that the long-term power
contracts  that DWR entered  into with these  energy  providers,  including  the
Company,  are rendered void because  Budhraja,  who  negotiated the contracts on
behalf of DWR, allegedly had an undisclosed  financial interest in the contracts
due to his  connection  to one of the energy  providers,  Edison  International.
Among other  things,  the  complaint  seeks an  injunction  prohibiting  further
performance  of the  long-term  contracts and  restitution  of any funds paid to
energy  providers by the State of California  under the  contracts.  The Company
considers the  allegations  against Calpine in this lawsuit to be without merit,
and intends to vigorously defend against them.

     Nevada  Section 206  Complaint.  On December 4, 2001,  NPC and SPPC filed a
complaint  with the FERC under  Section 206 of the  Federal  Power Act against a
number of parties to their power sales  agreements,  including the Company.  NPC
and SPPC allege in their complaint,  which seeks a refund,  that the prices they




                                      -23-


agreed to pay in certain of the power sales  agreements,  including those signed
with the  Company,  were  negotiated  during a time  when the power  market  was
dysfunctional and that they are unjust and  unreasonable.  The Company considers
the complaint to be without merit and is vigorously defending against it.

     Emissions Credits Lawsuit.  As described in previous  reports,  on March 5,
2002, the Company sued Automated  Credit Exchange  ("ACE") in the Superior Court
of the State of California  for the County of Alameda for  negligence and breach
of contract to recover reclaim  trading  credits,  a form of emission  reduction
credits  that should have been held in the  Company's  account  with U.S.  Trust
Company ("US Trust"). the Company and ACE entered into a settlement agreement on
March  29,  2002,  pursuant  to which ACE made a payment  to the  Company  of $7
million and  transferred  to the Company  the rights to the  emission  reduction
credits to be held by ACE. The Company  dismissed its complaint against ACE. The
Company  recognized the $7 million in the second quarter of 2002. In June 2002 a
complaint was filed by InterGen North America, L.P.  ("InterGen"),  against Anne
M. Sholtz, the owner of ACE, and EonXchange,  another  Sholtz-controlled entity,
which  filed for  bankruptcy  protection  on May 6,  2002.  InterGen  alleges it
suffered  a loss of  emission  reduction  credits  from  EonXchange  in a manner
similar to the the Company's loss from ACE.  InterGen's  complaint  alleges that
Anne Sholtz  co-mingled  assets among ACE,  EonXchange and other Sholtz entities
and that ACE and other  Sholtz  entities  should  be  deemed to be one  economic
enterprise and all retroactively included in the EonXchange bankruptcy filing as
of May 6, 2002.  InterGen's complaint refers to the payment by ACE of $7 million
to the Company,  alleging that InterGen's ability to recover from EonXchange has
been  undermined  thereby.  The  Company is unable to assess the  likelihood  of
InterGen's complaint being upheld at this time.

     The Company is involved in various other claims and legal  actions  arising
out of the normal course of its  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.

14.  Operating Segments

     The  Company's  primary  operating  segments  are electric  generation  and
marketing;  oil and gas production and marketing;  and corporate  activities and
other. Electric generation and marketing includes the development,  acquisition,
ownership and operation of power production facilities,  the sale of electricity
and steam and electricity hedging, balancing, optimization and trading activity.
Oil and gas production and marketing includes the ownership and operation of gas
fields, gathering systems and gas pipelines for internal gas consumption,  third
party  sales  and oil and  gas  hedging,  balancing,  optimization  and  trading
activity.  Corporate  activities  and  other  consists  primarily  of  financing
activities,  general and  administrative  costs and consolidating  eliminations.
Certain costs related to  company-wide  functions are allocated to each segment.
However,  interest on  corporate  debt is  maintained  at  corporate  and is not
allocated  to the  segments.  Due  to  the  integrated  nature  of the  business
segments,  estimates and judgments have been made in allocating  certain revenue
and expense items. The Company evaluates performance of these operating segments
based upon several criteria including profits before tax.

procured gas for the Company's  power plants,  are included in the Corporate and
Other reporting segment.

15.  California Power Market

On April 22, 2002, the Company announced that it had renegotiated CES' long-term
power  contracts  with  DWR.  The  Office of the  Governor  of  California,  the
California Public Utilities Commission (the "CPUC"), the California  Electricity
Oversight  Board (the  "EOB") and the  California  Attorney  General  (the "AG")
endorsed  the  renegotiated  contracts  and  agreed to drop all  pending  claims
against the Company and its  affiliates,  including  withdrawing  the  complaint
under  Section 206 of the Federal  Power Act that had been filed by the CPUC and
EOB with FERC,  and the  termination by the CPUC and the EOB of their efforts to
seek  refunds  from  the  Company  and  its   affiliates   through  FERC  refund
proceedings. In connection with the renegotiation, the Company has agreed to pay
$6 million  over three  years to the AG to resolve any and all  possible  claims
against the Company and its affiliates brought by the AG.

     CES had  signed  three  long-term  contracts  with  DWR in  February  2001,
comprising  two  10-year  baseload  energy  contracts  and one  20-year  peaking
contract.  The renegotiation provided for the shortening of the duration of each
of the two 10-year,  baseload  energy  contracts by two years and of the 20-year
peaker contract by ten years.  These changes  reduced DWR's  long-term  purchase
obligations.  In addition, CES agreed to reduce the energy price on one baseload
contract  from  $61.00 to $59.60 per  megawatt-hour,  and to convert  the energy
portion of the peaker  contract to gas index pricing from fixed energy  pricing.
CES also  agreed to  deliver up to 12.2  million  megawatt-hours  of  additional
energy pursuant to the baseload energy contracts in 2002 and 2003. In connection
with the renegotiation, CES also agreed with DWR that DWR will have the right to
assume  and  complete  four of the  Company's  projects  currently  planned  for
California  and in the advanced  development  stage if the Company does not meet
certain  milestones  with respect to each  project  assumed,  provided  that DWR
reimburses  the  Company  for all  construction  costs and  certain  other costs
incurred  by the  Company to the date DWR  assumes  the  relevant  project.

     In addition,  the  negotiation  resolved  the dispute  with DWR  concerning
payment of the capacity payment on the peaking  contract.  The contract provides
that through December 31, 2002, CES may earn a capacity payment by committing to
supply  electricity to DWR from a source other than the peaker units  designated
in the  contract.  DWR had made  certain  assertions  challenging  CES' right to
substitute  units  or  provide  replacement  energy  and had  withheld  capacity
payments in the amount of  approximately  $15.0 million since  December 2001. As
part of the  renegotiation,  the Company has  received  payment in full on these
withheld  capacity  payments  and will  have the  right to  provide  replacement
capacity  through  December 31, 2002, on the original  contract terms. On May 2,
2002,  each of the CPUC and the EOB filed a Notice of  Partial  Withdrawal  with
Prejudice of Complaint as to Calpine Energy Services, L.P. with the FERC.

Selected Operating Information

     Set forth below is certain  selected  operating  information  for our power
plants and steam fields, for which results are consolidated in our statements of
operations.  Results vary for the three and six months  ended June 30, 2002,  as
compared  to the same  periods in 2001,  for the  reasons  discussed  more fully
throughout this Management's  Discussion and Analysis of Financial Condition and
Results  of  Operations.  Electricity  revenue  is  composed  of fixed  capacity
payments,  which are not related to production,  and variable  energy  payments,
which are related to production.  Capacity revenue includes, besides traditional
capacity  payments,  other revenues such as  reliability  must run and ancillary
service  revenues.  The  information  set forth under  thermal and other revenue
consists of host thermal sales and other revenue (revenues in thousands).

     Credit  restrictions  on certain  Calpine  Energy  Services,  L.P.  ("CES")
activities in 2002 could negatively impact the volume of hedging,  balancing and
optimization activities in the future.

     Megawatt hours produced at the power plants increased 100% and 101% for the
three and six months  ended June 30,  2002,  as compared to the same  periods in
2001.  This was  primarily  due to the addition of power plants that were either
acquired or commenced  commercial  operation  subsequent  to June 30, 2001.  The
decrease in average all-in electricity price per megawatt hour generated in 2002
reflects the  softening  market  conditions in 2002 for power.  The  information
above is related to our generating assets and excludes trading  activities which
are discussed in the Results of Operations and Performance Metrics below.

     The increase in electricity and steam revenues due to the addition of power
plants was moderated by the reduction in CES's trading activities due to current
market conditions. However, we will evaluate alternatives as they are identified
for relationships  with potential  partners to strengthen our ability to conduct
risk management activities and to support the credit requirements of its trading
activities, but will proceed only if any such arrangement adds value to us.

     The accounting  requirements  under Staff Accounting  Bulletin ("SAB") 101,
"Revenue  Recognition in Financial  Statements"  and Emerging  Issues Task Force
("EITF") Issue No. 99-19,  "Reporting Revenue Gross as a Principal versus Net as
an Agent" require us to show most of our hedging  contracts on a gross basis (as
opposed  to  netting  sales and cost of  revenue).  The  primary  reason for the
significant increase in these sales and cost of revenue in 2002 as compared with
2001 is the growth of our generation  activity in 2002 as compared with 2001 and
the  corresponding  increase in hedging,  balancing,  optimization,  and trading
activities.

     Rules in effect  throughout 2002 and 2001 associated with the NEPOOL market
in New England  require that all power  generated in NEPOOL be sold  directly to
the Independent System Operator ("ISO") in that market; we then buy from the ISO
to serve our customer contracts. Generally accepted accounting principles in the
United States of America require us to account for this activity,  which applies
to three of our merchant generating facilities, as the aggregate of two distinct
sales and one purchase. This gross basis presentation increases revenues but not
gross profit.  The table below details the financial  extent of our transactions
with NEPOOL for the period  indicated.  The decrease in 2002 is primarily due to
lower prices in 2002, partially offset by increased volume.

Three Months Ended June 30, 2002, Compared to Three Months Ended June 30, 2001.

     Revenue -- Total revenue increased to $1,941.8 million for the three months
ended June 30, 2002, compared to $1,612.9 million for the same period in 2001.

     Electric  generation and marketing revenue increased to $1,583.5 million in
2002 compared to $1,257.3 million in 2001.  Approximately  $203.0 million of the
$326.1 million variance was due to electricity and steam sales,  which increased
due to our growing  portfolio of power  plants.  Generation  almost  doubled but
average pricing dropped by 17%,  moderating  revenue growth. Our revenue for the
period ended June 30,  2002,  includes the  consolidated  results of  additional
facilities that we acquired or completed  construction on subsequent to June 30,
2001.  Sales of purchased  power grew by $185.4  million due to increased  price
hedging,   balancing  and  optimization  activity  around  our  operating  plant
portfolio  during the three  months  ended June 30,  2002.  This was offset by a
$62.3 million decrease in electric power derivative  mark-to-market gain. In the
three months ended June 30, 2001,  we  recognized a  significant  mark-to-market
gain from power  contracts  in a market  area  where we did not have  generation
assets. Due to industry-wide  credit restrictions on risk management and trading
activities in 2002, such  opportunities  and other trading  activities have been
greatly restricted.

     Oil and gas production and marketing revenue increased to $354.2 million in
2002 compared to $343.0  million in 2001. The increase is due to a $75.4 million
increase in sales of purchased  gas,  offset by a $64.2 million  decrease in oil
and gas sales to third parties  primarily  because of much lower average natural
gas pricing in 2002.

     Cost of revenue -- Cost of revenue  increased  to $1,685.5  million in 2002
compared to $1,308.6  million in 2001.  Approximately  $42.9  million and $115.4
million  of the  $376.9  million  increase  relates to the cost of power and gas
purchased by our energy services  organization,  respectively,  due to increased
price hedging,  balancing,  optimization  and trading  activities.  Fuel expense
increased  55%, from $228.4 million in 2001 to $354.1 million in 2002, due to an
increase  of  122%  in  gas-fired   megawatt   hours   generated  as  offset  by
significantly  lower gas prices in 2002 and an  improvement in average heat rate
of our generation  portfolio.  Plant operating  expense  increased by 71.7% from
$69.3 million to $118.9 million but, expressed per MWh of generation,  decreased
from  $8.79/MWh to $7.57/MWh as economies of scale are being realized due to the
increase  in  the  average  size  of our  plants.  Depreciation,  depletion  and
amortization  expense  increased by 52.6%, from $72.1 million to $110.1 million,
due primarily to additional power facilities in consolidated  operations at June
30, 2002, as compared to the same period in 2001.

     Project  development expense -- Project development expense increased $20.3
million as we expensed  $18.1  million in costs related to the  cancellation  or
indefinite suspension of certain development projects.

     Merger  expense -- The merger  expense of $35.6 million in the three months
ended June 30, 2001 was a result of the  pooling-of-interests  transaction  with
Encal Energy Ltd.

     Interest expense -- Interest  expense  increased 54.8% to $67.1 million for
the three months ended June 30, 2002,  from $43.3 million for the same period in
2001.   Interest  expense  increased  primarily  due  to  the  issuance  of  the
Convertible Senior Notes Due 2006 and additional senior notes in the second half
of 2001 and due to the fact that interest expense on construction projects stops
being capitalized once the project goes into commercial operations and a greater
number of projects went into commercial operation in the three months ended June
30, 2002,  than in the three months  ended June 30, 2001.  Interest  capitalized
increased  from $115.6 million in the three months ended June 30, 2001 to $171.0
million in the three months ended June 30, 2002,  as a  consequence  of a larger
construction  portfolio in 2002. We expect that  interest  expense will increase
and the amount of interest capitalized will decrease in the future as our plants
in construction are completed, and also as a result of the current suspension of
our development projects.

     Interest income -- Interest income  decreased to $9.8 million for the three
months  ended June 30,  2002,  compared to $20.5  million for the same period in
2001.  This decrease is due primarily to lower cash balances and interest  rates
in 2002.

     Other income -- Other  income  declined by $0.5 million in the three months
ended June 30, 2002,  compared to the same period in 2001. In the 2002 period we
recognized  $7.0  million of  recovery  from ACE for losses  incurred on reclaim
trading  credit  transactions  (see Note 13 to the  financial  statements),  and
additionally,  we recognized  gains from asset sales of $7.6  million.  However,
these gains were partially offset by letter of credit fees of $6.2 million, $3.4
million for cost of a forfeited deposit on an asset purchase that did not close,
foreign exchange  translation losses of $2.0 million, due primarily to weakening
in the Canadian dollar,  and minority  interest expense of $0.9 million.  In the
corresponding period in 2001, we had a foreign exchange translation gain of $3.0
million.




                                      -28-


     Provision  for  income  taxes  --  The   effective   income  tax  rate  was
approximately 32.9% and 39.1% for the three months ended June 30, 2002 and 2001,
respectively. The decrease in rates was due to our expansion into Canada and the
United  Kingdom and our cross border  financings,  which  reduced our  effective
blended  tax rates and due to the  reversal  of $2.6  million of a specific  tax
reserve in 2002.

     Extraordinary  loss,  net -- The $1.3  million  charge  (net of tax of $0.8
million) in the three  months  ended June 30,  2001  related to the write off of
unamortized  deferred  financing  costs as a result of the repayment of the $105
million 9 1/4% Senior Notes Due 2004.

Six Months Ended June 30, 2002, Compared to Six Months Ended June 30, 2001.

     Revenue -- Total revenue  increased to $3,680.2  million for the six months
ended June 30, 2002, compared to $2,952.6 million for the same period in 2001.

     Electric  generation and marketing revenue increased to $3,116.1 million in
2002  compared to $2,307.4  million in 2001.  Sales of  purchased  power grew by
$640.1  million due to  increased  price  hedging,  balancing  and  optimization
activity around our operating  plant portfolio  during the six months ended June
30, 2002.  Approximately  $228.1  million of the variance was due to electricity
and steam sales,  which increased due to our growing  portfolio of power plants.
Generation  more than doubled,  but average  pricing  dropped by 30% to moderate
revenue  growth.  Our revenue for the period ended June 30,  2002,  includes the
consolidated  results of  additional  facilities  that we acquired or  completed
construction on subsequent to June 30, 2001. The increase in electric generation
and marketing  revenue was offset by a $59.5 million  decrease in electric power
derivative  mark-to-market  gain.  In the six  months  ended June 30,  2001,  we
recognized a significant  mark-to-market  gain from power  contracts in a market
area  where we did not  have  generation  assets.  Due to  industry-wide  credit
restrictions   on  risk   management  and  trading   activities  in  2002,  such
opportunities and other trading activities have been greatly restricted.

     Oil and gas production and marketing revenue decreased to $553.9 million in
2002  compared to $628.9  million in 2001.  The decrease is  primarily  due to a
$153.4  million  decrease in oil and gas sales to third parties  because of much
lower average natural gas pricing in 2002, offset by a $78.3 million increase in
the sales of purchased gas.

     Cost of revenue -- Cost of revenue  increased  to $3,245.9  million in 2002
compared to $2,372.8  million in 2001.  Approximately  $401.6 million and $120.5
million  of the  $873.1  million  increase  relates to the cost of power and gas
purchased by our energy  services  organization,  respectively  due to increased
price hedging,  balancing,  optimization  and trading  activities.  Fuel expense
increased 41.5%, from $485.4 million in 2001 to $686.9 million in 2002, due to a
127% increase in gas-fired  megawatt hours generated as offset by  significantly
lower gas prices and an improved  average heat rate of our generation  portfolio
in 2002.  Plant  operating  expense  increased  by 52.3% from $153.7  million to
$234.1 million but,  expressed per MWh of generation,  decreased from $10.17/MWh
to $7.69/MWh as economies of scale are being realized due to the increase in the
average size of our plants.  Royalty  expense  decreased  $9.6  million  between
periods  due to a  decrease  in  revenue  for  The  Geysers  geothermal  plants.
Depreciation, depletion and amortization expense increased by 48.4%, from $144.2
million to $214.0  million,  due  primarily to  additional  power  facilities in
consolidated  operations  at June 30,  2002,  as  compared to the same period in
2001.   Operating   lease  expense   increased  30.5%  between  periods  due  to
sale/leaseback transactions subsequent to June 30, 2001.

     Project  development expense -- Project development expense increased 78.4%
as we expensed $22.3 million in costs related to the  cancellation or indefinite
suspension of certain development projects.

     Equipment cancellation cost -- The pre-tax equipment cancellation charge of
$168.5  million in the six months  ended June 30,  2002,  was as a result of the
turbine order  cancellations  and the  cancellation  of certain other  equipment
based primarily on forfeited prepayments to date.

     General and administrative  expense -- General and  administrative  expense
increased  31.4% to $113.9  million for the six months ended June 30,  2002,  as
compared  to  $86.6  million  for the same  period  in 2001.  The  increase  was
attributable  to continued  growth in personnel and  associated  overhead  costs
necessary  to support the  overall  growth in our  operations  and due to recent
acquisitions, including power facilities and natural gas operations. General and
administrative expense expressed per MWh of generation decreased to $3.74/MWh in
2002 from $5.73/MWh in 2001.

     Merger  expense  -- The merger  expense of $41.6  million in the six months
ended June 30, 2001 was a result of the  pooling-of-interests  transaction  with
Encal Energy Ltd.

     Interest expense -- Interest expense increased 102.9% to $128.4 million for
the six months  ended June 30, 2002,  from $63.3  million for the same period in
2001.   Interest  expense  increased  primarily  due  to  the  issuance  of  the



                                      -29-


     Convertible Senior Notes Due 2006 and additional senior notes in the second
half of 2001 and due to the new plants going into commercial operations at which
point capitalization of interest expense ceases.  Interest capitalized increased
from $219.6  million in the six months ended June 30, 2001 to $334.1  million in
the six months ended June 30, 2002,  due to a larger  construction  portfolio in
2002. We expect that  interest  expense will continue to increase and the amount
of  interest  capitalized  will  decrease  in future  periods  as our  plants in
construction  are completed,  and also as a result of the current  suspension of
our development projects.

     Interest income -- Interest  income  decreased to $21.9 million for the six
months  ended June 30,  2002,  compared to $39.9  million for the same period in
2001.  This decrease is due primarily to lower cash balances and interest  rates
in 2002.

     Other  income -- Other  income  increased by $2.8 million in the six months
ended June 30, 2002,  compared to the same period in 2001. In the 2002 period we
recognized  $7.0  million of  recovery  from ACE for losses  incurred on reclaim
trading  credit  transactions  (see Note 13 to the  financial  statements),  and
additionally,  we recognized net gains from asset sales of $18.8 million,  which
was  primarily  due to a gain of $9.7 million from the sale of our  interests in
the Lockport project, gains of $4.3 million from sales of non-strategic Canadian
properties, and a gain of $2.7 million from the sale of our 7.5% interest in the
Bayonne project.  However, these gains were partially offset by letter of credit
fees of $6.2 million,  $3.4 million for cost of a forfeited  deposit on an asset
purchase that did not close, foreign exchange translation losses of $2.2 million
and minority interest expense of $0.9 million.  In the  corresponding  period in
2001, we had gains on sales of assets of $12.7  million,  primarily  from a $7.2
million gain on the sale of our development  interests in the Elwood project and
a gain of $4.9  million  from  the  sale of our  7.5%  interest  in the  Bayonne
project,  which was partially offset by a foreign  exchange  translation loss of
$2.4 million, due primarily to weakening in the Canadian dollar.

     Provision  for  income  taxes  --  The   effective   income  tax  rate  was
approximately  59.0% and 41.1% for the six months  ended June 30, 2002 and 2001,
respectively.  The  increase is not  meaningful  since the 2002  effective  rate
reflects  the  reversal of $2.6  million of specific  tax reserve in 2002 and is
applied to a small net loss.

     Extraordinary gain (loss), net -- The $2.1 million gain (net of tax of $1.4
million) in 2002 represents the repurchase of $192.5 million aggregate principal
amount of our Zero Coupon  Convertible  Debentures  Due 2021  ("Zero  Coupons"),
which was comprised  primarily of a $4.8 million gain from the repurchase of the
Zero Coupons at a discount,  partially  offset by a loss due to the write-off of
unamortized  deferred  financing  costs.  The $1.3 million charge (net of tax of
$0.8 million) in 2001 related to the write off of unamortized deferred financing
costs as a result of the  repayment  of the $105 million 9 1/4% Senior Notes Due
2004.

     Cumulative  effect of a change in  accounting  principle - In 2001 the $1.0
million  of  additional  income  (net  of tax of  $0.7  million),  is due to the
adoption of Financial Accounting Standards Board ("FASB") Statement of Financial
Accounting  Standards ("SFAS") No. 133,  "Accounting for Derivative  Instruments
and Hedging  Activities," as amended by SFAS No. 137, "Accounting for Derivative
Instruments  and Hedging  Activities  - Deferral of the  Effective  Date of FASB
Statement  No. 133 - an  Amendment  of FASB  Statement  No. 133," and as further
amended by SFAS No. 138,  "Accounting  for Certain  Derivative  Instruments  and
Certain Hedging Activities - an Amendment of FASB Statement No. 133."

Selected Balance Sheet Information

     Unconsolidated  Investments in Power Projects -- Although our preference is
to own 100% of the power plants we acquire or develop, there are situations when
we take  less  than  100%  ownership.  Reasons  why we may take less than a 100%
interest  in a  power  plant  may  include,  but  are not  limited  to:  (a) our
acquisitions of other IPPs such as  Cogeneration  Corporation of America in 1999
and SkyGen Energy LLC in 2000 in which minority  interest projects were included
in the  portfolio of assets owned by the  acquired  entities  (Grays Ferry Power
Plant (40% now owned by Calpine) and Androscoggin Energy Center (32.3% now owned
by Calpine);  (b) opportunities to co-invest with non-regulated  subsidiaries of
regulated electric utilities, which under the Public Utility Regulatory Policies
Act of  1978,  as  amended  are  restricted  to 50%  ownership  of  cogeneration
qualifying facilities -- such as our investment in Gordonsville Power Plant (50%
owned by Calpine and 50% owned by Edison Mission  Energy,  which is wholly-owned
by Edison  International  Company);  and (c) opportunities to invest in merchant
power projects with partners who bring marketing,  funding,  permitting or other
resources  that add value to a  project.  An  example  of this is Acadia  Energy
Center,  which is under  construction in Louisiana (50% owned by Calpine and 50%
owned by Cleco Midstream Resources, an affiliate of Cleco Corporation).  None of
our equity  investment  projects  have  nominal  carrying  values as a result of
material recurring losses.  Further, there is no history of impairment in any of
these investments.

     Accumulated other comprehensive loss -- The amount of the accumulated other
comprehensive  loss  decreased  from  $(226.6)  million at December 31, 2001, to
$(118.7)  million at June 30, 2002. The change resulted from unrealized gains on
derivatives  designated  as cash flow  hedges of $54.3  million,  net of amounts
reclassified to net loss and income taxes, and foreign currency translation gain
of $53.6 million. See Note 9 for further information.

Liquidity and Capital Resources

     General -- The latter half of 2001, and  particularly  the fourth  quarter,
saw the beginning of a significant  contraction in the  availability  of capital
for  participants  in the  energy  sector.  This was due to a range of  factors,
including  uncertainty  arising from the collapse of Enron and a perceived  near
term surplus supply of electric generating capacity.  While we have been able to
access the capital and bank credit  markets,  as discussed  below,  we recognize
that  terms  of  financing  available  to us now  and in the  future  may not be
attractive to us. To protect against this  possibility,  we have scaled back our
capital  expenditure  program  for 2002 and 2003 to  enable us to  conserve  our
available capital  resources,  but remain ready to access the capital markets as
attractive opportunities arise.

     To date, we have obtained cash from our  operations;  borrowings  under our
facilities  and  other  working  capital  lines;  sale of  debt,  equity,  trust
preferred  securities and convertible  debentures;  proceeds from sale/leaseback
transactions,  sale of  non-strategic  assets  and  project  financing.  We have
utilized  this  cash to fund our  operations,  service  debt  obligations,  fund
acquisitions, develop and construct power generation facilities, finance capital
expenditures,   support  our  hedging,   balancing,   optimization  and  trading
activities at CES, and meet our other cash and liquidity  needs. Our business is
capital  intensive.  Our  ability  to  capitalize  on  growth  opportunities  is
dependent on the availability of capital on attractive  terms; the timing of the
availability of such capital in today's  environment is uncertain.  Our strategy
is also to reinvest our cash from operations  into our business  development and
construction program, rather than to pay cash dividends.

     Factors  that could affect our  liquidity  and capital  resources  are also
discussed in the "Risk  Factors"  section of our Annual  Report on Form 10-K for
the year ended December 31, 2001.

     Cash  Flow  Activities  -- The  following  table  summarizes  our cash flow
activities for the periods indicated:



                                                                                      Six Months Ended June 30,

     Operating  activities for the six months ended June 30, 2002,  provided net
cash of $463.4 million,  compared to $90.0 million for the six months ended June
30, 2001.  The cash  provided by operating  activities  for the six months ended
June 30, 2002,  consisted  of a $227.5  million  decrease in  operating  assets,
primarily  relating to a $236.2  million  decrease in margin  deposits and other
prepaid  expenses.  This was offset by a $355.1  million  decrease in  operating
liabilities,  primarily related to derivative activity. A primary factor causing
the  significant  increase in cash flow from  operations in the six months ended
June 30, 2002, in comparison to the same period in 2001, is the  realization  of
over $200  million of  pre-bankruptcy  petition  PG&E  receivables  in the first
quarter  of  2002,  which  helped  our  operating  cash  flow  performance  and,
similarly,  the failure to collect those  receivables in the first half of 2001,
which reduced operating cash flow in that period.

     Investing  activities for the six months ended June 30, 2002,  consumed net
cash of $2.6 billion,  primarily due to $2.5 billion for construction  costs and
capital  expenditures  including  gas  turbine  generator  costs and  associated
capitalized  interest,  $43.8  million of advances to joint  ventures  including
associated   capitalized  interest  for  investments  in  power  projects  under
construction,  $63.7 million of capitalized  project development costs including
associated  capitalized  interest,  and a $27.8  million  increase in restricted
cash.  This was  partially  offset by a $49.8  million of  proceeds  on sales of
property, plant and equipment and investments in power projects.

                                      -31-


     Financing  activities for the six months ended June 30, 2002, provided $1.1
billion of net cash  consisting of $751.2  million of proceeds from the offering
of common  stock,  $100.0  million of proceeds  from the issuance of  additional
Convertible   Senior  Notes  Due  2006  pursuant  to  exercise  of  the  initial
purchasers' remaining purchase option, $1.1 billion of proceeds from drawings on
our term loan and revolving lines of credit, and $280.2 million of proceeds from
project  financing.  This  was  partially  offset  by  $873.2  million  for  the
repurchase of the outstanding  Zero Coupons,  $87.5 million for the repayment of
notes  payable  and  borrowings  under our lines of credit,  $92.2  million  for
repayments of project financing and $59.9 million of additional financing costs.

     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,  access to the  sale/leaseback  and other
markets,  sale  of  non-strategic  assets  and  cash  balances  to  satisfy  all
obligations  under  outstanding  indebtedness,  to finance  anticipated  capital
expenditures  and to fund  working  capital  requirements  for the  next  twelve
months.

     Enron  Bankruptcy -- We believe,  based on legal analysis,  that we have no
net  collection  exposure to Enron.  See Note 10 to the  Consolidated  Condensed
Financial Statements.

     Nevada Power and Sierra  Pacific  Power Company -- During the first quarter
of 2002, two  subsidiaries  of Sierra Pacific  Resources  Company,  Nevada Power
Company  ("NPC") and Sierra  Pacific Power  Company  ("SPPC"),  received  credit
downgrades  to  sub-investment  grades from the major  credit  rating  agencies.
Additionally,  NPC  acknowledged  liquidity  problems  created  when the  Public
Utilities  Commission of Nevada disallowed a rate adjustment requested by NPC to
cover the increased cost of buying power during the 2001 energy crisis.  NPC has
requested that its power suppliers  extend payment terms to help it overcome its
short-term liquidity problems.  During the second quarter of 2002, NPC indicated
to its power suppliers that it was experiencing cash flow difficulties.  In June
and July 2002 NPC underpaid us by approximately $4.2 million, and we expect that
NPC will underpay us by  approximately  an additional  $18.4 million this summer
and early fall. In consideration of the uncertainty surrounding NPC's ability to
make timely  payments,  we are  maintaining a bad debt reserve of  approximately
$2.7 million against NPC receivables.  See Part II -- Other Information - Item 1
for further discussion.

     As of June 30, 2002, we had net collection exposures of approximately $34.8
million and $20.2  million  with NPC and SPPC,  respectively.  However,  SPPC is
paying us currently. Our exposures include open forward power contracts that are
reported at fair value on our balance  sheet as well as  receivable  and payable
balances  relating to prior power  deliveries.  We are continuing to monitor our
exposure and its effect on our financial condition.

     PSM License  Receivable -- In December 2001 PSM and a Dutch power  services
company entered into a perpetual  world-wide  license  agreement for certain PSM
proprietary  reverse-flow  venturi  technology.  The license  fee,  while earned
upfront,  is payable over the period from January 2002 through  March 2004.  The
Company  recognized the license fee of $11 million (less imputed interest on the
receivable) as income in December 2001. As of the date of this filing, we have a
receivable  of $7 million,  with no payments  currently  past due.  The indirect
parent of the Dutch company,  a German holding company,  filed for insolvency in
Germany in July 2002 and the direct  parent of the Dutch  company is expected to
also file for insolvency.  However,  the Dutch company has assured us that it
has not and currently  does not expect to file for  insolvency in the near term.
We have been further  assured in a letter from the German holding  company dated
July 11,  2002,  that the Dutch  company  expects  to  continue  the  license
arrangement and to meet its obligations  thereunder.  Based on our evaluation of
these  and  other  factors,  a  loss  does  not  seem  probable  at  this  time.
Accordingly,  we have not established a reserve  against the related  receivable
but will continue to closely monitor the situation.

     CES Margin  Deposits and Other Credit  Support -- As of June 30, 2002,  CES
had $67.3  million  in cash on  deposit as margin  deposits  with third  parties
related to its business  activities and letters of credit outstanding in support
of CES business  activities of $315.0 million.  As of December 31, 2001, CES had
deposited  $345.5 million in cash as margin  deposits with third parties related
to its business  activities and letters of credit  outstanding in support of CES
business  activities of $259.4  million.  While we believe that we have adequate
liquidity to support CES'  operations  at this time,  it is difficult to predict
future developments and the amount of credit support that we may need to provide
as part of our business operations.

     Revised Capital Expenditure Program -- Following a comprehensive  review of
our power plant development  program,  we announced in January 2002 the adoption
of a revised capital expenditure  program,  which contemplated the completion of
27 power  projects  (representing  15,200 MW) then under  construction.  Nine of
these facilities have subsequently achieved full or partial commercial operation
as of June 30, 2002.  Construction  of advanced  stage  development  projects is




                                      -32-


expected to proceed only when there is an established market need for additional
generating  resources  at  prices  that  will  allow us to meet our  established
investment  criteria,  and when  capital  may again  become  available  to us on
attractive terms.  Further,  our entire development and construction  program is
flexible and subject to continuing review and revision based upon such criteria.

     On March  12,  2002,  we  announced  a new  turbine  program  that  reduces
previously forecasted capital spending by approximately $1.2 billion in 2002 and
$1.8 billion in 2003. The revision  includes adjusted timing of turbine delivery
and related payment  schedules and also cancellation of some orders. As a result
of these turbine cancellations and other equipment cancellations,  we recorded a
pre-tax charge of $168.5 million in the first quarter of 2002.

     Uses and Sources of Funding -- As of August 1, 2002,  our estimated uses of
funds  for 2002 are as  follows:  construction  costs of $2.6  billion,  cost to
repurchase  the  remaining  Zero Coupons of $0.9 billion,  other debt  repayment
costs of $0.1 billion, maintenance and gas capital expenditures of $0.3 billion,
cash  lease  payments  of $0.3  billion,  estimated  Enron  contract  settlement
payments of $0.1  billion and $0.7  billion for  turbines  for  financeable  and
future  projects.  These  uses of funds  will be  funded  primarily  through  an
estimated $0.8 billion of operating cash flow for 2002, $0.3 billion of CES cash
collateral  replaced  with  letters of credit  and cash on hand of $1.8  billion
(consists of cash on hand of $1.5  billion at December  31,  2001,  $0.2 billion
from the sale of the PG&E receivables, $0.1 billion from the sale of Convertible
Senior  Notes Due 2006 in early  January  2002).  The other  sources  of funding
include $1.0 billion  from the two-year  term loan,  $0.7 billion from the April
equity offering,  $0.6 billion from our construction  revolvers and our proposed
California  peaker  leases,  as well as $0.3 billion from our secured  revolving
credit facilities.  We are also negotiating the sale of non-strategic assets for
approximately  $0.3 billion.  Other potential sources of cash include monetizing
our Canadian power generation  assets for approximately  $0.3 billion,  entering
into a  sale/leaseback  transaction  for our Zion  facility for cash proceeds of
$0.2  billion,  selling our Gilroy note  receivable  for $0.2  billion,  selling
certain additional assets, including oil and gas properties, for proceeds net of
debt  repayment of $0.4 billion,  and financing for our future  turbines of $0.3
billion.  Actual costs for the projected uses of funds identified above, and net
proceeds from the projected  sources of funds  identified  above could vary from
those estimates, potentially in material respects. Factors that could affect the
accuracy of these  estimates are discussed in our Annual Report on Form 10-K for
the year ended December 31, 2001, in the "Risk Factors" section.

     Capital  Availability  --  Notwithstanding   recent  uncertainties  in  the
domestic energy and capital markets,  we raised  substantial  capital earlier in
2002.  On April 30, 2002,  we completed a public  offering of common stock of 66
million  shares and priced the offering at $11.50 per share.  The proceeds after
underwriting  fees totaled $734.3  million.  The proceeds from the offering were
used to repay debt and for general corporate purposes.

     On May 14, 2002, our subsidiary,  Calpine  California Energy Finance,  LLC,
entered into an amended and restated  credit  agreement with ING Capital LLC for
the funding of 9 California peaker facilities, of which $100.0 million was drawn
on May 24,  2002.  The total $100.0  million  funding is  classified  as current
project  financing,  of which $50.0  million  was repaid on August 7, 2002,  and
$50.0 million will be payable on September 30, 2002. This peaker funding is part
of our expected long-term financing of our California peaker facilities which is
anticipated to be $500.0 million.

     During the second  quarter of 2002, we increased our two-year  secured bank
term loan to $1.0 billion from $600 million, and reduced the size of our secured
corporate revolving credit facilities to $1.0 billion from $1.4 billion. At June
30, 2002,  we had $1.0  billion in  borrowings  outstanding  under the term loan
facility and $75.0 million in borrowings  outstanding under the revolving credit
facility.

     Letter of  credit  facilities  -- At June 30,  2002,  we had  approximately
$874.6  million in letters of credit  outstanding  under various  credit support
facilities,  including facilities related to CES risk management activities, and
other  operational and construction  activities.  Of the total letters of credit
outstanding,  $723.2  million were issued under the corporate  revolving  credit
facilities.  At December  31, 2001,  we had $642.5  million in letters of credit
outstanding, including facilities relating to CES risk management activities.

     Off-Balance  Sheet  Commitments -- In accordance  with SFAS No. 13 and SFAS
No. 98,  "Accounting  for Leases" our operating  leases are not reflected on our
balance sheet. We have also entered into sale/leaseback  transactions  involving
our Tiverton,  Rumford,  South Point,  Broad River,  and RockGen  projects.  All
counterparties in these transactions are third parties that are unrelated to us.
The sale/leaseback  transactions utilize special-purpose  entities formed by the
equity investors with the sole purpose of owning a power generation facility. We
have no ownership or other  interest in any of these  special-purpose  entities.
Some of our  operating  leases  contain  customary  restrictions  on  dividends,
additional  debt and further  encumbrances  similar to those  typically found in
project finance debt instruments.




                                      -33-


     In accordance  with APB Opinion No. 18 "The Equity Method of Accounting For
Investments  in Common  Stock" and FASB  Interpretation  No. 35,  "Criteria  for
Applying the Equity Method of  Accounting  for  Investments  in Common Stock (An
Interpretation  of  APB  Opinion  No.  18),"  the  debt  on  the  books  of  our
unconsolidated  investments  in power  projects is not  reflected on our balance
sheet. At June 30, 2002, investee debt totaled $660.6 million.  Based on our pro
rata  ownership  share of each of the  investments,  our  share  would be $244.8
million. However, all such debt is non-recourse to us. For the Aries Power Plant
construction  debt, we and Aquila  Energy,  a wholly owned  subsidiary of Aquila
Inc, have provided support arrangements until construction is completed to cover
cost overruns, if any. Additionally, one of our projects with an operating lease
has $237.8 million of debt outstanding at June 30, 2002.

Performance Metrics

     In understanding our business,  we believe that certain performance metrics
are particularly important. These include:

     o    Average gross profit margin based on pro forma (non-GAAP)  revenue and
          pro forma (non-GAAP) cost of revenue.  A high percentage of our recent
          revenue has  consisted of CES hedging,  balancing,  optimization,  and
          trading  activity  undertaken  primarily  to enhance  the value of our
          generating assets (see "Marketing, Hedging, Optimization, and Trading"
          subsection  of the  Business  Section  of our 2001 Form  10-K).  CES's
          hedging,  balancing,  optimization,  and trading activity is primarily
          accomplished  by buying  and  selling  electric  power and  buying and
          selling natural gas or by entering into gas financial instruments such
          as exchange-traded  swaps or forward contracts.  Under SAB No. 101 and
          EITF No. 99-19,  we must show the  purchases and sales of  electricity
          and gas on a gross basis in our statement of operations when we act as
          a  principal,  take title to the  electricity  and gas we purchase for
          resale,  and  enjoy  the  risks  and  rewards  of  ownership.  This is
          notwithstanding  the  fact  that  the net  gain  or  loss  on  certain
          financial hedging  instruments,  such as  exchange-traded  natural gas
          price swaps, is shown as a net item in our GAAP financials. Because of
          the  inflating  effect on revenue of much of our  hedging,  balancing,
          optimization, and trading activity, we believe that revenue levels and
          trends do not reflect our  performance  as accurately as gross profit,
          and that it is  analytically  useful to look at our  results  on a pro
          forma, non-GAAP basis with all hedging, balancing,  optimization,  and
          trading  activity netted.  This analytical  approach nets the sales of
          purchased  power with  purchased  power expense (with the exception of
          net realized sales and expenses on electrical trading activity,  which
          is shown on a net basis in sales of purchased power) and includes that
          net amount as an adjustment to E&S revenue for our generation  assets.
          Similarly,  we believe that it is analytically useful to net the sales
          of purchased gas with purchased gas expense (with the exception of net
          realized sales and expenses on gas trading activity, which is shown on
          a net basis in sales of purchased  gas) and include that net amount as
          an adjustment to cost of oil and natural gas burned by power plants, a
          component  of fuel  expense.  This  allows us to look at all  hedging,
          balancing,   optimization,  and  trading  activity  consistently  (net
          presentation) and better understand our performance  trends. It should
          be noted that in this non-GAAP analytical approach, total gross profit
          does not  change  from the GAAP  presentation,  but the  gross  profit
          margins  as a percent of revenue  do differ  from  corresponding  GAAP
          amounts  because  the  inflating  effects on our  revenue of  hedging,
          balancing, optimization, and trading activities are removed.

     o    Average  availability  and average  capacity factor or operating rate.
          Availability  represents  the percent of total hours during the period
          that our plants were  available  to run after  taking into account the
          downtime associated with both scheduled and unscheduled  outages.  The
          capacity  factor,  sometimes  called  operating rate, is calculated by
          dividing  (a) total  megawatt  hours  generated  by our  power  plants
          (excluding  peakers) by multiplying (b) the weighted average megawatts
          in  operation  during the period by (c) the total hours in the period.
          The capacity factor is thus a measure of total actual  generation as a
          percent of total  potential  generation.  If we elect not to  generate
          during periods when  electricity  pricing is too low or gas prices too
          high to operate  profitably,  the  capacity  factor will  reflect that
          decision  as well as both  scheduled  and  unscheduled  outages due to
          maintenance and repair requirements.

     o    Average heat rate for  gas-fired  fleet of power  plants  expressed in
          Btu's of fuel  consumed per KWh  generated.  We calculate  the average
          heat  rate for our  gas-fired  power  plants  (excluding  peakers)  by
          dividing  (a)  fuel  consumed  in  Btu's  by (b)  KWh  generated.  The
          resultant heat rate is a measure of fuel efficiency,  so the lower the
          heat rate, the better. We also calculate a "steam-adjusted" heat rate,
          in  which  we  adjust  the  fuel  consumption  in  Btu's  down  by the
          equivalent heat content in steam or other thermal energy exported to a
          third party,  such as to steam hosts for our cogeneration  facilities.
          Our goal is to have the lowest average heat rate in the industry.



                                      -34-


     o    Average all-in  realized  electric price  expressed in dollars per MWh
          generated.  We calculate the all-in  realized  electric  price per MWh
          generated  by  dividing  (a)  adjusted  E&S  revenue,  which  includes
          capacity revenues, energy revenues, thermal revenues and the spread on
          sales  of   purchased   electricity   for  hedging,   balancing,   and
          optimization activity, by (b) total generated MWh's in the period.

     o    Average cost of natural gas expressed in dollars per millions of Btu's
          of fuel consumed.  At Calpine,  the fuel costs for our gas-fired power
          plants are a function of the price we pay for fuel  purchased  and the
          results of the fuel hedging, balancing, and optimization activities by
          CES. Accordingly, we calculate the cost of natural gas per millions of
          Btu's of fuel  consumed in our power  plants by dividing  (a) adjusted
          cost of oil and natural gas burned by power plants which  includes the
          cost of fuel consumed by our plants (adding back cost of  intercompany
          "equity"  gas  from  Calpine  Natural  Gas,  which  is  eliminated  in
          consolidation),  and the spread on sales of purchased gas for hedging,
          balancing,  and  optimization  activity  by (b) the  heat  content  in
          millions of Btu's of the fuel we consumed in our power  plants for the
          period.

     o    Average spark spread expressed in dollars per MWh generated.  Our risk
          management  activities  focus on  managing  the spark  spread  for our
          portfolio  of power  plants,  the spread  between  the sales price for
          electricity  generated  and the cost of fuel.  We calculate  the spark
          spread per MWh generated by  subtracting  (a) adjusted cost of oil and
          natural gas burned by power  plants from (b)  adjusted E&S revenue and
          dividing the difference by (c) total generated MWh's in the period.

     The  table  below  presents,  side-by-side,  both our  GAAP  and pro  forma
non-GAAP netted revenue, costs of revenue and gross profit showing the purchases
and sales of  electricity  and gas for  hedging,  balancing,  optimization,  and
trading  activity on a net basis.  It also shows the other  performance  metrics
discussed above.

Outlook

     At August 9, 2002, we had 25 projects under  construction,  representing an
additional  11,650  megawatts of net  capacity.  The  completion of our projects
currently  under  construction,  which we expect  to occur in the later  half of
2004, would give us interests in 96 power plants totaling 28,539 megawatts.

     Our new $2 billion revolving credit and term loan facilities and April 2002
issuance  of 66  million  shares  of  common  stock  together  with our  ongoing
financing programs and sales of non-strategic  assets have helped to improve our
2002 liquidity position.  For 2003 to 2004, our secured  construction  financing
revolving facilities will mature,  requiring us to restructure or refinance this
indebtedness.  We remain  confident  that we will have the ability to  refinance
this indebtedness as it matures, but recognize that this is dependent,  in part,
on market  conditions  that are  difficult  to  predict  and are  outside of our
control.  We have made  significant  progress in  reducing  our  operations  and
maintenance costs and general and administrative expenses per unit of electrical
generation  as we have doubled our  generation  of  electricity  from the second
quarter of 2001 to the second quarter of 2002 and, as a result of the suspension
of certain of our  development  projects  and the  restructuring  of our turbine
contracts  completed to date,  our capital  expenditure  requirements  have been
reduced.  We recognize that the pace of pricing and spark spread  improvement is
dependent on the nation's economic recovery and on weather,  particularly in the
summer and winter periods.  We remain confident in our strategy,  as outlined in
our  Annual  Report on Form  10-K for the year  ended  December  31,  2001,  and
optimistic about our future performance. However, market conditions make it more
difficult to predict future results than in prior  periods.  Additional  factors
that can affect our  future  performance  are  described  in the "Risk  Factors"
section of our Annual Report on Form 10-K for the year ended December 31, 2001.

California Power Market

     On April 22, 2002, we announced  that we had  renegotiated  CES'  long-term
power  contracts with the California  Department of Water Resources (the "DWR").
The Office of the  Governor  of  California,  the  California  Public  Utilities
Commission (the "CPUC"), the California  Electricity Oversight Board (the "EOB")
and the  California  Attorney  General  (the  "AG")  endorsed  the  renegotiated
contracts and agreed to drop all pending claims  against us and our  affiliates,
including  withdrawing  the complaint under Section 206 of the Federal Power Act
that had been filed by the CPUC and EOB with FERC,  and the  termination  by the
CPUC and the EOB of their  efforts to seek  refunds  from us and our  affiliates
through FERC refund proceedings.  In connection with the renegotiation,  we have
agreed to pay $6  million  over  three  years to the AG to  resolve  any and all
possible claims against us and our affiliates brought by the AG.

     CES had  signed  three  long-term  contracts  with  DWR in  February  2001,
comprising  two  10-year  baseload  energy  contracts  and one  20-year  peaking
contract.  The renegotiation provided for the shortening of the duration of each
of the two 10-year,  baseload  energy  contracts by two years and of the 20-year
peaker contract by ten years.  These changes  reduced DWR's  long-term  purchase
obligations.  In addition, CES agreed to reduce the energy price on one baseload
contract  from  $61.00 to $59.60 per  megawatt-hour,  and to convert  the energy
portion of the peaker  contract to gas index pricing from fixed energy  pricing.
CES also  agreed to  deliver up to 12.2  million  megawatt-hours  of  additional
energy pursuant to the baseload energy contracts in 2002 and 2003. In connection
with the renegotiation, CES also agreed with DWR that DWR will have the right to
assume and complete four of our projects currently planned for California and in
the advanced development stage if we do not meet certain milestones with respect
to each project  assumed,  provided that DWR reimburses us for all  construction
costs  and  certain  other  costs  incurred  by us to the date DWR  assumes  the
relevant project. The Company will generate over $8.7 billion in revenue between
2002 and 2011 from the DWR contracts.

     In addition,  the  negotiation  resolved  the dispute  with DWR  concerning
payment of the capacity payment on the peaking  contract.  The contract provides
that through December 31, 2002, CES may earn a capacity payment by committing to
supply  electricity to DWR from a source other than the peaker units  designated
in the  contract.  DWR had made  certain  assertions  challenging  CES' right to
substitute  units  or  provide  replacement  energy  and had  withheld  capacity
payments in the amount of  approximately  $15.0 million since  December 2001. As
part of the  renegotiation,  we have received  payment in full on these withheld
capacity  payments  and will  have the  right to  provide  replacement  capacity
through December 31, 2002, on the original  contract terms. On May 2, 2002, each
of the CPUC and the EOB filed a Notice of Partial  Withdrawal  with Prejudice of
Complaint as to Calpine Energy Services, L.P. with the FERC.

Financial Market Risks

     As an  independent  power  producer  primarily  focused  on  generation  of
electricity using gas-fired turbines, our natural physical commodity position is
"short" fuel (i.e.,  natural gas consumer)  and "long" power (i.e.,  electricity
seller).  To manage  forward  exposure to price  fluctuation  in these and (to a
lesser  extent)  other   commodities,   we  enter  into   derivative   commodity
instruments.  We enter into commodity financial  instruments to convert floating
or indexed  electricity and gas (and to a lesser extent oil and refined product)
prices to fixed prices in order to lessen our  vulnerability  to  reductions  in
electric prices for the electricity we generate, to reductions in gas prices for
the gas we produce,  and to  increases  in gas prices for the fuel we consume in
our power plants.  We seek to "self-hedge"  our gas  consumption  exposure to an
extent  with  our  own gas  production  position.  Any  hedging,  balancing,  or
optimization   activities  that  we  engage  in  are  directly  related  to  our
asset-based  business  model of owning and operating  gas-fired  electric  power
plants and are designed to protect our "spark  spread" (the  difference  between
our fuel cost and the revenue we receive for our electric generation).  We hedge
exposures  that arise  from the  ownership  and  operation  of power  plants and
related  sales of  electricity  and  purchases  of natural  gas,  and we utilize
derivatives to optimize the returns we are able to achieve from these assets for
our  shareholders.  From time to time we have entered into contracts  considered
energy trading  contracts under EITF Issue No. 98-10,  "Accounting for Contracts
Involved in Energy Trading and Risk Management Activities." However, our traders
have low  capital at risk and value at risk limits for energy  trading,  and our
risk management  policy limits, at any given time, our net sales of power to our
generation  capacity and limits our net purchases of gas to our fuel consumption
requirements on a total portfolio basis.  This model is markedly  different from
that of companies that engage in significant  commodity trading  operations that
are unrelated to underlying physical assets.  Derivative  commodity  instruments
are  accounted  for under the  requirements  of SFAS No.  133 and EITF Issue No.

     Derivative  commodity  instruments included in the table are those included
in Note 8 to the unaudited Consolidated Condensed Financial Statements. The fair
value of  derivative  commodity  instruments  included  in the table is based on
present  value  adjusted  quoted  market  prices of  comparable  contracts.  The
positive fair value of electricity derivative commodity instruments includes the
effect of decreased  power prices  versus our  derivative  forward  commitments.
Conversely,  the negative fair value of the natural gas  derivatives  reflects a
general  decline  in gas  prices  versus  our  derivative  forward  commitments.
Derivative  commodity  instruments offset physical positions exposed to the cash
market.  None of the  offsetting  physical  positions  are included in the table
above.

     Price changes were calculated by assuming an  across-the-board  ten percent
adverse price change regardless of term or historical  relationship  between the
contract price of an instrument and the underlying commodity price. In the event
of an  actual  ten  percent  change  in  prices,  the fair  value  of  Calpine's
derivative portfolio would typically change by more than ten percent for earlier
forward months and less than ten percent for later forward months because of the
higher  volatilities  in the near term and the effects of  discounting  expected
future cash flows.

     The primary  factors  affecting  the fair value of our  derivatives  at any
point in time are (1) the volume of open derivative  positions  (MMBtu and MWh),
and (2) changing  commodity  market  prices,  principally  for  electricity  and
natural gas. The total volume of open gas  derivative  positions  decreased  58%
from December 31, 2001,  to June 30, 2002,  while the total volume of open power
derivative  positions  decreased  10% for the same  period.  In that  prices for
electricity and natural gas are among the most volatile of all commodity prices,
there may be material  changes in the fair value of our  derivatives  over time,
driven both by price  volatility  and the  changes in volume of open  derivative
transactions.  Under SFAS No. 133, the change since the last balance  sheet date
in the total value of the derivatives (both assets and liabilities) is reflected
either in other comprehensive income ("OCI"), net of tax, or in the statement of
operations as an item (gain or loss) of current  earnings.  As of June 30, 2002,
the majority of the balance in accumulated  OCI  represented  the unrealized net
loss associated with commodity cash flow hedging  transactions.  As noted above,
there is a substantial amount of volatility  inherent in accounting for the fair
value of these derivatives, and our results during the six months ended June 30,
2002, have reflected  this. See Note 8 for additional  information on derivative
activity and also the 2001 Form 10-K for a further  discussion of our accounting
policies  related to derivative  accounting.  How we account for our derivatives
depends upon whether we have  designated  the  derivative as a cash flow or fair
value  hedge or not  designated  the  derivative  in a hedge  relationship.  The
following accounting applies:

                                      -42-


     o    Changes in the value of  derivatives  designated  as cash flow hedges,
          net of any ineffectiveness, are recorded to OCI.

     o    Changes in the value of  derivatives  designated  as fair value hedges
          are recorded in the statement of operations with the offsetting change
          in  value  of  the  hedge  item  also  recorded  in the  statement  of
          operations.  Any difference between these two entries to the statement
          of operations represents hedge ineffectiveness.

     o    The  change  in  value  of   derivatives   not   designated  in  hedge
          relationships is recorded to the statement of operations.

     In 2001  the FASB  cleared  SFAS  No.  133  Implementation  Issue  No.  C16
"Applying  the Normal  Purchases  and Normal Sales  Exception to Contracts  That
Combine a  Forward  Contract  and a  Purchased  Option  Contract"  ("C16").  The
guidance in C16  applies to fuel supply  contracts  that  require  delivery of a
contractual  minimum  quantity  of fuel at a fixed price and have an option that
permits  the  holder to take  specified  additional  amounts of fuel at the same
fixed price at various times. Under C16, the volumetric  optionality provided by
such  contracts is considered a purchased  option that  disqualifies  the entire
derivative  fuel supply  contract from being  eligible to qualify for the normal
purchases  and normal  sales  exception  in SFAS No. 133.  On April 1, 2002,  we
adopted C16. We have no fuel supply contracts to which C16 applies. However, one
of our equity  method  investees has fuel supply  contracts  subject to C16. The
equity  investee  also  adopted  C16 on April 1,  2002.  Because  the  contracts
qualified as highly effective hedges of the equity method investee's  forecasted
purchase of gas, the equity  method  investee  designated  the contracts as cash
flow  hedges.  Accordingly,  we  have  recorded  $7.8  million  net  of tax as a
cumulative effect of change in accounting  principle to OCI for its share of the
equity method investee's OCI from accounting change.

     Interest rate swaps and cross  currency  swaps -- From time to time, we use
interest rate swap and cross  currency swap  agreements to mitigate our exposure
to interest rate and currency  fluctuations  associated with certain of our debt
instruments.  We do not use interest rate swap and currency swap  agreements for
speculative  or trading  purposes.  In regards to foreign  currency  denominated
senior  notes,  the swap  notional  amounts  equal  the  amount  of the  related
principal  debt.  The following  tables  summarize the fair market values of our
existing  interest rate swap and currency  swap  agreements as of June 30, 2002,

     Long-term senior notes and construction/project financing -- Because of the
significant capital  requirements within our industry,  additional  financing is
often needed to fund our growth.  We use two primary forms of debt to raise this
financing  --  long-term   senior  notes  and  related   instruments   including
Convertible Senior Notes Due 2006 and construction/project financing. Our senior
notes and related  instruments  bear fixed interest rates and are generally used
to fund acquisitions,  replace construction financing for power plants once they
achieve  commercial   operations,   and  for  general  corporate  purposes.  Our
construction/project financing is funded through two separate credit agreements,
Calpine  Construction  Finance  Company  L.P. and Calpine  Construction  Finance
Company II, LLC. Borrowings under these credit agreements bear variable interest
rates, and are used exclusively to fund the construction of our power plants.

     Short-term   investments  --  As  of  June  30,  2002,  we  had  short-term
investments of $190.0 million.  These short-term  investments  consist of highly
liquid  investments with original  maturities of less than three months. 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.

     Construction/project  financing  facilities  -- In 2003  and  2004,  $981.4
million and  $2,452.7  million,  respectively,  under our  secured  construction
financing  revolving  facilities  will mature,  requiring  us to refinance  this
indebtedness.  We remain  confident  that we will have the ability to  refinance
this indebtedness as it matures, but recognize that this is dependent,  in part,
on market conditions that are difficult to predict.

New Accounting Pronouncements

     In June  2001 we  adopted  SFAS No.  141,  "Business  Combinations,"  which
supersedes  Accounting  Principles  Board  ("APB")  Opinion  No.  16,  "Business
Combinations" and SFAS No. 38, "Accounting for  Preacquisition  Contingencies of
Purchased Enterprises." SFAS No. 141 eliminated the pooling-of-interests  method
of  accounting  for  business  combinations  and  modified  the  recognition  of
intangible assets and disclosure requirements.  Adoption of SFAS No. 141 did not
have a material effect on the consolidated financial statements.

     In June 2001 the FASB issued SFAS No. 142,  "Goodwill and Other  Intangible
Assets," which supersedes APB Opinion No. 17, "Intangible  Assets." SFAS No. 142
eliminates  the current  requirement to amortize  goodwill and  indefinite-lived
intangible  assets,  extends the  allowable  useful lives of certain  intangible
assets,  and  requires  impairment  testing and  recognition  for  goodwill  and
intangible  assets.  SFAS No. 142 will apply to  goodwill  and other  intangible
assets arising from  transactions  completed both before and after its effective
date.  The  provisions of SFAS No. 142 are required to be applied  starting with
fiscal years beginning after December 15, 2001. See Note 4 for more information.

     In June 2001 the FASB issued SFAS No. 143, "Accounting for Asset Retirement
Obligations,"  which amends SFAS No. 19, "Financial  Accounting and Reporting by
Oil and Gas Producing  Companies." SFAS No. 143 addresses  financial  accounting
and  reporting  for  obligations  associated  with the  retirement  of  tangible
long-lived  assets  and the  associated  asset  retirement  costs.  SFAS No. 143
requires that the fair value of a liability for an asset  retirement  obligation
be recognized in the period in which it is incurred if a reasonable  estimate of





                                      -44-


fair  value can be made.  SFAS No. 143 is  effective  for  financial  statements
issued for fiscal years  beginning  after June 15, 2002.  We do not believe that
SFAS  No.  143  will  have  a  material  impact  on our  consolidated  financial
statements.

     On January 1, 2002, we adopted SFAS No. 144, "Accounting for the Impairment
or Disposal of Long-Lived  Assets," which  supersedes SFAS No. 121,  "Accounting
for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed
Of,"  and the  accounting  and  reporting  provisions  of APB  Opinion  No.  30,
"Reporting  the Results of  Operations -- Reporting the Effects of Disposal of a
Segment of a Business,  and  Extraordinary,  Unusual and Infrequently  Occurring
Events and  Transactions,"  for the  disposal  of a segment  of a  business  (as
previously  defined  in that APB  Opinion).  SFAS No. 144  establishes  a single
accounting  model,  based on the  framework  established  in SFAS No.  121,  for
long-lived  assets to be disposed of by sale. SFAS No. 144 also resolves several
significant  implementation  issues related to SFAS No. 121, such as eliminating
the  requirement  to  allocate  goodwill to  long-lived  assets to be tested for
impairment and  establishing  criteria to define  whether a long-lived  asset is
held for sale.  Adoption  of SFAS No. 144 has not had a  material  effect on the
consolidated financial statements.

     In April 2002 the FASB issued SFAS No. 145,  "Rescission of FASB Statements
No.  4,  44,  and  64,  Amendment  of  FASB  Statement  No.  13,  and  Technical
Corrections." SFAS No. 145 rescinds SFAS No. 4, "Reporting Gains and Losses from
Extinguishment  of Debt"  and an  amendment  of that  statement,  SFAS  No.  64,
"Extinguishments of Debt Made to Satisfy Sinking-Fund Requirements" stating that
gains or losses from  extinguishment  of debt that fall outside the scope of APB
Opinion  No. 30 should not be  classified  as  extraordinary.  SFAS No. 145 also
amends SFAS No. 13,  "Accounting  for  Leases," to  eliminate  an  inconsistency
between the required accounting for sale-leaseback transactions and the required
accounting for certain lease  modifications  that have economic effects that are
similar to sale-leaseback transactions.  SFAS No. 145 also amends other existing
authoritative  pronouncements  to make various  technical  corrections,  clarify
meanings,  or  describe  their  applicability  under  changed  conditions.   The
provisions  related to the  rescission  of SFAS No. 4 shall be applied in fiscal
years beginning after May 15, 2002. The provisions  related to SFAS No. 13 shall
be effective for transactions occurring after May 15, 2002. All other provisions
shall be effective  for  financial  statements  issued on or after May 15, 2002,
with early adoption  encouraged.  We have not completed our analysis but believe
that  SFAS  No.  145 may  have a  material  effect  on the  presentation  of our
financial statements, but no impact on net income.

     In June 2002 the FASB issued SFAS No. 146, "Accounting for Costs Associated
with Exit or Disposal  Activities," which addresses accounting for restructuring
and  similar  costs.  SFAS No.  146  supersedes  previous  accounting  guidance,
principally  EITF Issue No. 94-3,  "Liability  Recognition for Certain  Employee
Termination  Benefits  and Other  Costs to Exit an Activity  (Including  Certain
Costs  Incurred in a  Restructuring)."  We will adopt the provisions of SFAS No.
146 for restructuring activities initiated after December 31, 2002. SFAS No. 146
requires  that the  liability  for  costs  associated  with an exit or  disposal
activity be recognized  when the liability is incurred.  Under Issue No. 94-3, a
liability  for an exit cost was  recognized at the date of commitment to an exit
plan.  SFAS No. 146 also  establishes  that the  liability  should  initially be
measured  and recorded at fair value.  Accordingly,  SFAS No. 146 may affect the
timing  of  recognizing  future  restructuring  costs  as  well  as the  amounts
recognized.  We do not believe that SFAS No. 146 will have a material  effect on
our consolidated financial statements.

     In June  2002 the EITF  reached  a  consensus  on two of the  three  issues
considered  in EITF 02-03,  "Recognition  and  Reporting  of Gains and Losses on
Energy Trading Contracts under EITF Issues No. 98-10,  `Accounting for Contracts
Involved  in Energy  Trading  and Risk  Management  Activities'  and No.  00-17,
`Measuring  the Fair Value of  Energy-Related  Contracts  in applying  Issue No.
98-10.'"  The  issues  upon  which the EITF  reached a  consensus  required  net
presentation, both prospective and retroactive, of energy trading contracts in a
company's  financial   statements  and  required  that  companies  make  certain
disclosures  regarding  their energy  trading  contracts.  The net  presentation
requirement  is effective for  financial  statements  issued for periods  ending
after July 15, 2002, and the disclosure requirements are effective for financial
statements  issued for fiscal years  ending  after July 15,  2002.  We are still
assessing the impacts of adopting this standard on our financial statements, but
we believe,  as a minimum,  all energy  trading  contracts will be reported net,
rather than gross,  upon adoption of this standard.  The standard is expected to
have a material  impact on total  revenues  and  expenses,  but no impact on net
income.

                           PART II - OTHER INFORMATION

Item 1. Legal Proceedings.

     Securities  Derivative Lawsuit. On December 17, 2001, a shareholder filed a
derivative  lawsuit on behalf of Calpine  against our  directors  and one of our
senior officers.  This lawsuit is captioned  Johnson v. Cartwright,  et al. (No.
CV803872),  and is pending in the California Superior Court, Santa Clara County.
Calpine is a nominal defendant in this lawsuit, which alleges claims relating to
purportedly  misleading  statements  about Calpine and stock sales by certain of
the  director  defendants  and the officer  defendant.  We have filed a demurrer
asking the court to dismiss the  complaint  on the ground  that the  shareholder
plaintiff  lacks standing to pursue claims on behalf of Calpine.  The individual
defendants  have filed a demurrer  asking the court to dismiss the  complaint on
the ground that it fails to state any claims  against  them.  We  consider  this
lawsuit to be without merit and intend to vigorously defend against it.

     Securities Class Action Lawsuits.  Fourteen  shareholder lawsuits have been
filed against  Calpine and certain of its officers in the United States District
Court,  Northern District of California.  The actions captioned Weisz v. Calpine
Corp., et al., filed March 11, 2002, and Labyrinth Technologies, Inc. v. Calpine
Corp.,  et al., filed March 28, 2002,  are purported  class actions on behalf of
purchasers  of Calpine  stock  between  March 15,  2001,  and December 13, 2001.
Gustaferro v. Calpine Corp.,  filed April 18, 2002, is a purported  class action
on behalf of purchasers of Calpine stock between  February 6, 2001, and December
13, 2001.  The eleven other  actions,  captioned  Local 144 Nursing Home Pension
Fund v.  Calpine  Corp.,  Lukowski v.  Calpine  Corp.,  Hart v.  Calpine  Corp.,
Atchison v. Calpine Corp., Laborers Local 1298 v. Calpine Corp., Bell v. Calpine
Corp.,  Nowicki v. Calpine Corp.,  Pallotta v. Calpine Corp., Knepell v. Calpine
Corp.,  Staub v. Calpine  Corp.,  and Rose v. Calpine  Corp.  were filed between
March 18, 2002,  and April 23, 2002.  The complaints in these eleven actions are
virtually  identical--they  were filed by three law firms,  in conjunction  with
other law firms as co-counsel.  All eleven  lawsuits are purported class actions
on behalf of purchasers of our securities  between January 5, 2001, and December
13, 2001.

     The complaints in these fourteen actions allege that,  during the purported
class periods,  certain senior  Calpine  executives  issued false and misleading
statements  about our  financial  condition in  violation of Sections  10(b) and
20(1) of the  Securities  Exchange  Act of 1934,  as well as Rule  10b-5.  These
actions  seek an  unspecified  amount of damages,  in addition to other forms of
relief. We expect that these actions, as well as any related actions that may be
filed in the future,  will be consolidated by the court into a single securities
class action.

     In addition,  a fifteenth  securities class action, Ser v. Calpine, et al.,
was filed on May 13,  2002.  The  underlying  allegations  in the Ser action are
substantially the same to those in the  above-referenced  actions.  However, the
Ser action is brought on behalf of a purported  class of  purchasers of our 8.5%
Senior Notes due February 15, 2011 ("2011 Notes"),  and the alleged class period
is October 15, 2001,  through December 13, 2001. The Ser complaint alleges that,
in violation of Sections 11 and 15 of the Securities Act of 1933, the Prospectus
Supplement  dated  October  11,  2001,  for the 2011 Notes  contained  false and
misleading  statements  regarding  our  financial  condition.  This action names
Calpine, certain of our officers and directors, and the underwriters of the 2011
Notes offering as defendants,  and seeks an  unspecified  amount of damages,  in
addition  to other  forms of relief.  We expect  that this action will either be
consolidated  with the  above-referenced  actions or will  proceed as a parallel
related  action  before  the same judge  presiding  over the other  actions.  We
consider the allegations against Calpine in each of these lawsuits to be without
merit, and we intend to defend vigorously against them.

     California  Business & Professions Code Section 17200 Cases--The lead case,
T&E Pastorino Nursery v. Duke Energy Trading and Marketing,  L.L.C., et al., was
served on May 2, 2002,  by T&E Pastorino  Nursery,  on behalf of itself and all
others similarly situated.  This purported class action complaint against twenty
energy  traders and energy  companies  including  CES,  alleges that  defendants
exercised  market  power and  manipulated  prices  in  violation  of  California
Business & Professions Code Section 17200 et seq., and seeks injunctive  relief,
restitution and attorneys' fees.

     We also have been named in five other similar  complaints for violations of
Section 17200 captioned  Bronco Don Holdings,  LLP. v. Duke Energy Marketing and
Trading, et al.; Century Theatres, Inc. v. Allegheny Energy Supply Company, LLC;
RDJ Farms,  Inc. v.  Allegheny  Energy Supply  Company,  LLC; J&M Karsant Family
Limited Partnership v. Duke Energy Trading and Marketing, LLC; and Leo's Day and
Night Pharmacy v. Duke Energy Trading and Marketing, LLC. All six of these cases
have been  removed in a  multidistrict  litigation  proceeding  from the various
state  courts in which  they were  originally  filed to federal  court,  where a
motion is now  pending to transfer  and  consolidate  these  cases for  pretrial
proceedings  with  other  cases  in which we are not  named as a  defendant.  In
addition,  plaintiffs in the T&E  Pastorino  Nursery case have filed a motion to
remand that matter to California state court.

     We consider the allegations against Calpine in each of these lawsuits to be
without merit, and we intend to vigorously defend against them.

                                      -46-


     California  Department of Water Resources Case. On May 1, 2002,  California
State  Senator  Tom  McClintock  and others  filed a  complaint  against  Vikram
Budhraja,  a consultant to DWR, DWR itself, and more than twenty-nine energy
providers and other interested parties, including Calpine. The complaint alleges
that the  long-term  power  contracts  that DWR entered  into with these  energy
providers, including Calpine, are rendered void because Budhraja, who negotiated
the contracts on behalf of DWR, allegedly had an undisclosed  financial interest
in the contracts due to his  connection to one of the energy  providers,  Edison
International. Among other things, the complaint seeks an injunction prohibiting
further performance of the long-term contracts and restitution of any funds paid
to energy providers by the State of California under the contracts.  We consider
the  allegations  against Calpine in this lawsuit to be without merit and intend
to vigorously defend against them.

     Nevada  Section 206  Complaint.  On December 4, 2001,  NPC and SPPC filed a
complaint with the Federal Energy Regulatory  Commission  ("FERC") under Section
206 of the  Federal  Power Act  against a number of parties to their power sales
agreements,  including  Calpine.  NPC and SPPC allege in their complaint,  which
seeks a refund, that the prices they agreed to pay in certain of the power sales
agreements,  including those signed with Calpine,  were negotiated during a time
when  the  power  market  was   dysfunctional  and  that  they  are  unjust  and
unreasonable.  We consider the complaint to be without merit and are  vigorously
defending against it.

     Emissions Credits Lawsuit.  As described in our previous reports,  on March
5, 2002, we sued Automated  Credit Exchange ("ACE") in the Superior Court of the
State of  California  for the County of  Alameda  for  negligence  and breach of
contract  to recover  reclaim  trading  credits,  a form of  emission  reduction
credits that should have been held in our account with U.S.  Trust  Company ("US
Trust").  Calpine and ACE entered into a settlement agreement on March 29, 2002,
pursuant to which ACE made a payment to us of $7 million and  transferred  to us
the rights to the emission reduction credits to be held by ACE, and we dismissed
our complaint against ACE. We recognized the $7 million in the second quarter of
2002.  In June  2002 a  complaint  was filed by  InterGen  North  America,  L.P.
("InterGen"),  against Anne M. Sholtz, the owner of ACE, and EonXchange, another
Sholtz-controlled  entity, which filed for bankruptcy protection on May 6, 2002.
InterGen  alleges  it  suffered  a  loss  of  emission  reduction  credits  from
EonXchange  in a manner  similar  to our loss  from  ACE.  InterGen's  complaint
alleges  that Anne Sholtz  co-mingled  assets  among ACE,  EonXchange  and other
Sholtz  entities and that ACE and other Sholtz  entities  should be deemed to be
one  economic  enterprise  and  all  retroactively  included  in the  EonXchange
bankruptcy filing as of May 6, 2002.  InterGen's complaint refers to the payment
by ACE of $7 million to us,  alleging  that  InterGen's  ability to recover from
EonXchange has been undermined  thereby.  We are unable to assess the likelihood
of InterGen's complaint being upheld at this time.

     We are involved in various  other claims and legal  actions  arising out of
the normal  course of our  business.  We do not expect that the outcome of these
proceedings  will have a material  adverse  effect on our financial  position or
results of operations.

Item 4. Submission of Matters to a Vote of Security Holders.

     Our Annual Meeting of  Stockholders  was held on May 23, 2002, (the "Annual
Meeting") in Aptos, California. At the Annual Meeting, the stockholders voted on
the following matters:  (i) the proposal to elect two Class III Directors to the
Board of Directors for a term of three years expiring in 2005, (ii) the proposal
to amend the Company's  1996 Stock  Incentive Plan to increase by 12 million the
number  of shares  of the  Company's  Common  Stock,  par value  $.001 per share
("Common Stock")  available for grants of options and other  stock-based  awards
under such plan,  (iii) the proposal to amend the Company's  2000 Employee Stock
Purchase Plan to increase by 8 million the number of Common Stock  available for
grants of  purchase  rights  under such  plan,  (iv) two  stockholder  proposals
regarding (a) the  composition  of the Company's  Board of Directors and (b) the
Company's stockholder rights plan, (v) the proposal to ratify the appointment of
Deloitte & Touche LLP as independent  accountants for the Company for the fiscal
year ending December 31, 2002. The stockholders elected management's nominees as
the Class III Directors in an  uncontested  election,  approved the amendment to
the Company's 1996 Stock  Incentive Plan to increase by 12 million the number of
shares of the Company's  Common Stock  available for grants of options and other
stock-based awards under such plan, approved the amendment to the Company's 2000
Employee Stock Purchase Plan to increase by 8 million the number of Common Stock
available  for  grants  of  purchase  rights  under  such  plan,   rejected  the
stockholder  proposal  regarding  the  composition  of the  Company's  Board  of
Directors,  approved  the  stockholder  proposal  that the Board of Directors be
requested to redeem the stockholders  right plan unless such plan is approved by
a majority vote of the  stockholders  to be held as soon as may be  practicable,
and ratified the appointment of independent  accountants by the following votes,
respectively:
