                      CALPINE CORPORATION AND SUBSIDIARIES

              NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS
                                  June 30, 2005
                                   (Unaudited)

1.   Organization and Operations of the Company

     Calpine   Corporation,    a   Delaware   corporation,    and   subsidiaries
(collectively,  "Calpine"  or the  "Company")  is engaged in the  generation  of
electricity  predominantly  in the United  States of  America  and  Canada.  The
Company is involved in the development, construction, 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,  pipelines,  geothermal steam fields and geothermal power generation
facilities  in the  United  States of  America.  On July 7,  2005,  the  Company
completed the sale of substantially all of its remaining oil and gas exploration
and production  assets. In Canada,  the Company has ownership  interests in, and
operates,  gas-fired power generation facilities.  In Mexico, Calpine is a joint
venture participant in a gas-fired power generation facility under construction.
At June 30, 2005, the Company owned and operated a gas-fired power  cogeneration
facility in the United  Kingdom,  but sold this  facility on July 28, 2005.  The
Company markets electricity  produced by its generating  facilities to utilities
and other third party purchasers. Thermal energy produced by the gas-fired power
cogeneration  facilities  is primarily  sold to  industrial  users.  The Company
offers to third parties  energy  procurement,  liquidation  and risk  management
services, combustion turbine component parts and repair and maintenance services
world-wide.  The Company also provides  engineering,  procurement,  construction
management, commissioning and O&M services.

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, 2004, 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.

     Reclassifications  -- Certain  prior  years'  amounts  in the  Consolidated
Condensed  Financial  Statements  have been  reclassified to conform to the 2005
presentation.   This  includes  a   reclassification   to  separately   disclose
transmission  sales revenue  (formerly in other revenue).  The 2004 amounts have
also been restated for discontinued operations. See Note 8 for more information.
In  addition,  the  Company had certain  reclassifications  on its  Consolidated
Condensed Statement of Cash Flows to conform to the 2005 presentation.

     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  associated   reserves,
capitalization  of  interest,   impairment   assessments,   primary  beneficiary
determination  for the  Company's  investments  in VIEs,  the outcome of pending
litigation  and  estimates of oil and gas reserve  quantities  used to calculate
depletion,  depreciation  and  impairment  of oil and gas property and equipment
(prior to the July 2005 disposition).

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

     The Company has certain  project  finance  facilities and lease  agreements
that establish  segregated  cash  accounts.  These accounts have been pledged as
security in favor of the lenders to such project finance facilities, and the use
of certain cash balances on deposit in such  accounts with our project  financed
subsidiaries  is limited to the operations of the respective  projects.  At June
30,  2005,  and  December  31,  2004,   $253.3   million  and  $284.4   million,
respectively, of the cash and cash equivalents balance that was unrestricted was
subject to such project finance facilities and lease agreements. In addition, at
June  30,  2005 and  December  31,  2004,  $56.8  million  and  $232.4  million,
respectively,  of the  Company's  cash  and  cash  equivalents  was held in bank
accounts outside the United States.

     Effective  Tax  Rate -- For the  three  months  ended  June 30,  2005,  the
effective  rate from  continuing  operations  decreased  to 32.7% as compared to
39.5% for the three months  ended June 30,  2004.  For the six months ended June
30, 2005 and 2004, the effective tax rate was 33.8% and 39.0%, respectively. The
tax rates on continuing operations for the quarter and six months ended June 30,
2004,  have been  restated  to  reflect  the  reclassification  to  discontinued
operations of certain tax expense related to the sale of the Company's remaining
oil  and  gas  reserves  and  Saltend.  See  Note  8  for  more  information  on
discontinued  operations.  This  effective tax rate on continuing  operations is
based on the  consideration  of estimated  year-end  earnings in estimating  the
quarterly  effective  rate,  the  effect  of  permanent  non-taxable  items  and
establishment of valuation allowances on certain deferred tax assets.

     Preferred Interests -- As outlined in SFAS No. 150, "Accounting for Certain
Financial  Instruments with Characteristics of both Liabilities and Equity," the
Company classifies  preferred interests that embody obligations to transfer cash
to the preferred  interest  holder,  in short-term  and  long-term  debt.  These
instruments  require the Company to make  priority  distributions  of  available
cash, as defined in each preferred interest agreement,  representing a return of
the preferred interest holder's  investment over a fixed period of time and at a
specified  rate of return in priority to certain other  distributions  to equity
holders.  The return on  investment  is recorded as interest  expense  under the
interest method over the term of the priority period.

     Long-Lived Assets and Impairment Evaluation -- In accordance with Financial
Accounting  Standards Board ("FASB") Statement of Financial Accounting Standards
("SFAS")  No. 144,  "Accounting  for the  Impairment  or Disposal of  Long-Lived
Assets," the Company  evaluates the impairment of long-lived  assets,  including
construction and development projects by first estimating projected undiscounted
pre-interest  expense and pre-tax  expense cash flows whenever events or changes
in  circumstances  indicate that the carrying  amounts of such assets may not be
recoverable.   The  significant   assumptions  that  the  Company  uses  in  its
undiscounted  future cash flow  estimates  include the future  supply and demand
relationships  for  electricity  and natural gas,  and the expected  pricing for
those  commodities  and the resultant spark spreads in the various regions where
the  Company  generates.  In the event  such cash flows are not  expected  to be
sufficient to recover the recorded  value of the assets,  the assets are written
down to their estimated fair values.  Certain of the Company's generating assets
are located in regions  with  depressed  demands and market spark  spreads.  The
Company's  forecasts  assume that spark spreads will increase in future years in
these regions as the supply and demand  relationships  improve.  There can be no
assurance  that  this  will  occur.  See  Note  5 for  more  information  on the
impairment  charge  recorded in the period ended June 30,  2005,  related to the
Morris facility, which was sold in July 2005.

     Stock-Based  Compensation -- On January 1, 2003, the Company  prospectively
adopted  the  fair  value  method  of  accounting   for   stock-based   employee
compensation  pursuant to SFAS No. 123 as amended by SFAS No. 148.  SFAS No. 148
amends SFAS No. 123 to provide  alternative  methods of transition for companies
that voluntarily  change their accounting for stock-based  compensation from the
less  preferred  intrinsic  value based method to the more  preferred fair value
based  method.  Prior to its  amendment,  SFAS No. 123 required  that  companies
enacting a voluntary  change in accounting  principle  from the intrinsic  value
methodology  provided by APB  Opinion  No. 25 could only do so on a  prospective
basis;  no adoption or transition  provisions  were  established  to allow for a
restatement  of prior  period  financial  statements.  SFAS No. 148 provides two
additional transition options to report the change in accounting  principle--the
modified   prospective   method   and  the   retroactive   restatement   method.
Additionally, SFAS No. 148 amends the disclosure requirements of SFAS No. 123 to
require prominent  disclosures in both annual and interim  financial  statements
about the method of accounting for  stock-based  employee  compensation  and the
effect of the method used on reported results.  The Company elected to adopt the
provisions of SFAS No. 123 on a prospective basis; consequently,  the Company is
required to provide a pro-forma  disclosure of net income and EPS as if SFAS No.
123  accounting  had been  applied  to all prior  periods  presented  within its
financial statements.  The adoption of SFAS No. 123 has had a material impact on
the  Company's  financial  statements.  The table below  reflects  the pro forma
impact of stock-based  compensation on the Company's net loss and loss per share
for the three and six  months  ended  June 30,  2005 and 2004,  had the  Company
applied the accounting provisions of SFAS No. 123 to its financial statements in
years prior to adoption of SFAS No. 123 on January 1, 2003 (in thousands, except
per share amounts):

New Accounting Pronouncements

  SFAS No. 123-R

     In  December  2004,  FASB  issued SFAS No. 123  (revised  2004)  ("SFAS No.
123-R"),   "Share  Based  Payments."  This  Statement   revises  SFAS  No.  123,
"Accounting  for  Stock-Based  Compensation"  and supersedes APB Opinion No. 25,
"Accounting  for Stock  Issued to  Employees,"  and its  related  implementation
guidance.  This  statement  requires  a public  entity  to  measure  the cost of
employee services received in exchange for an award of equity  instruments based
on the grant-date fair value of the award (with limited exceptions),  which must
be  recognized  over the period  during which an employee is required to provide
service in exchange for the award -- the requisite  service period  (usually the
vesting period).  The statement applies to all share-based payment  transactions
in which an entity  acquires goods or services by issuing (or offering to issue)
its  shares,  share  options,  or  other  equity  instruments  or  by  incurring
liabilities to an employee or other  supplier (a) in amounts based,  at least in
part,  on the price of the entity's  shares or other equity  instruments  or (b)
that require or may require  settlement by issuing the entity's equity shares or
other equity instruments.

     The  statement  requires the  accounting  for any excess tax benefits to be
consistent  with the  existing  guidance  under SFAS No. 123,  which  provides a
two-transaction model summarized as follows:

     o    If  settlement  of an  award  creates  a tax  deduction  that  exceeds
          compensation  cost,  the additional tax benefit would be recorded as a
          contribution to paid-in-capital.

     o    If the  compensation  cost  exceeds  the  actual  tax  deduction,  the
          write-off of the unrealized excess tax benefits would first reduce any
          available paid-in capital arising from prior excess tax benefits,  and
          any remaining amount would be charged against the tax provision in the
          income statement.

     The Company is still  evaluating  the impact of adopting  and  subsequently
accounting for excess tax benefits under the two-transaction  model described in
SFAS No.  123,  but does not expect  its  consolidated  net income or  financial
position to be materially affected upon adoption of SFAS No. 123-R.

     The  statement  also  amends  SFAS No. 95,  "Statement  of Cash  Flows," to
require that excess tax benefits be reported as a financing  cash inflow  rather
than as an operating  cash inflow.  However,  the statement  does not change the
accounting guidance for share-based payment transactions with parties other than
employees  provided  in SFAS No.  123 as  originally  issued  and EITF Issue No.
96-18,  "Accounting  for  Equity  Instruments  That Are  Issued  to  Other  Than
Employees for  Acquiring,  or in Conjunction  with Selling,  Goods or Services."
Further,  this  statement  does not address the  accounting  for employee  share
ownership  plans,  which  are  subject  to AICPA  Statement  of  Position  93-6,
"Employers' Accounting for Employee Stock Ownership Plans."

     The statement  applies to all awards  granted,  modified,  repurchased,  or
cancelled  after  January 1,  2006,  and to the  unvested  portion of all awards
granted  prior to that  date.  Public  entities  that used the  fair-value-based
method for either  recognition  or disclosure  under SFAS No. 123 may adopt this
Statement  using  a  modified  version  of  prospective   application  (modified
prospective application).  Under modified prospective application,  compensation
cost for the portion of awards for which the  employee's  requisite  service has
not been rendered that are  outstanding as of January 1, 2006 must be recognized
as the  requisite  service is rendered on or after that date.  The  compensation
cost for that portion of awards shall be based on the original  grant-date  fair
value of those  awards as  calculated  for  recognition  under SFAS No. 123. The
compensation  cost for those  earlier  awards  shall be  attributed  to  periods
beginning on or after January 1, 2006 using the attribution method that was used
under SFAS No. 123. Furthermore,  the method of recognizing forfeitures must now
be  based  on an  estimated  forfeiture  rate  and can no  longer  be  based  on
forfeitures as they occur.

     Adoption  of SFAS No.  123-R  is not  expected  to  materially  impact  the
Company's consolidated results of operations,  cash flows or financial position,
due to the Company's  prior adoption of SFAS No. 123 as amended by SFAS No. 148,
"Accounting  for  Stock-Based  Compensation  -- Transition  and  Disclosure"  on
January 1, 2003.  SFAS No. 148 allowed  companies to adopt the  fair-value-based
method  for  recognition  of  compensation  expense  under  SFAS No.  123  using
prospective application.  Under that transition method, compensation expense was
recognized  in the  Company's  Consolidated  Statement  of  Operations  only for
stock-based  compensation  granted  after the adoption  date of January 1, 2003.
Furthermore,  as we have chosen the  multiple  option  approach  in  recognizing
compensation  expense  associated  with the fair value of each  option  granted,
nearly 94% of the total fair value of the stock option is  recognized by the end
of the third year of the vesting period,  and therefore  remaining  compensation
expense  associated  with options granted before January 1, 2003, is expected to
be immaterial.

  SFAS No. 128-R

     FASB is expected to revise  SFAS No. 128,  "Earnings  Per Share" to make it
consistent with International  Accounting Standard No. 33, "Earnings Per Share,"
so that EPS computations will be comparable on a global basis. This new guidance
is  expected  to be issued by the end of 2005 and will  require  restatement  of
prior periods diluted EPS data. The proposed changes will affect the application
of the treasury  stock method and  contingently  issuable  (based on  conditions
other than market price) share guidance for computing  year-to-date diluted EPS.
In addition to modifying the year-to-date  calculation  mechanics,  the proposed
revision to SFAS No. 128 would  eliminate a  company's  ability to overcome  the
presumption of share  settlement for those  instruments or contracts that can be
settled, at the issuer or holder's option, in cash or shares.  Under the revised
guidance, FASB has indicated that any possibility of share settlement other than
in an event of bankruptcy  will require a presumption of share  settlement  when
calculating   diluted  EPS.  The  Company's  2023  Convertible  Notes  and  2014
Convertible Notes contain  provisions that would require share settlement in the
event of conversion  under certain limited events of default,  including but not
limited  to a  bankruptcy-related  event  of  default.  Additionally,  the  2023
Convertible  Notes  include a provision  allowing the Company to meet a put with
either cash or shares of stock.  However,  the Company's 2015 Convertible  Notes
allow  for  share  settlement  of the  principal  only in the  case  of  certain
bankruptcy-related  events  of  default.   Therefore,  a  presumption  of  share
settlement is not required for this  instrument.  The revised  guidance,  if not
amended  before final  issuance,  would  increase the potential  dilution to the
Company's EPS, particularly when the price of the Company's common stock is low,
since the more dilutive of calculations would be used considering both:

     o    normal  conversion  assuming a combination of cash and variable number
          of shares; and

     o    conversion  during  certain  limited  events of default  assuming 100%
          shares  at the  fixed  conversion  rate,  or,  in  the  case  of  2023
          Convertible Notes, meeting a put entirely with shares of stock.

  SFAS No. 151

     In November 2004, FASB issued SFAS No. 151,  "Inventory Costs, an amendment
of ARB No. 43,  Chapter 4." This  Statement  amends the  guidance in ARB No. 43,
Chapter 4, "Inventory  Pricing," to clarify the accounting for abnormal  amounts
of  idle  facility  expense,   freight,  handling  costs,  and  wasted  material
(spoilage).  Paragraph  5 of ARB 43,  Chapter 4,  previously  stated that ". . .
under  some  circumstances,  items  such as  idle  facility  expense,  excessive
spoilage,  double freight, and rehandling costs may be so abnormal as to require
treatment as current period charges.  . . ." This Statement requires those items
to be recognized as a current-period  charge regardless of whether they meet the
criterion of "so abnormal." In addition,  SFAS No. 151 requires that  allocation
of fixed production  overheads to the costs of conversion be based on the normal
capacity  of the  production  facilities.  The  provisions  of SFAS No.  151 are
applicable to inventory  costs incurred during fiscal years beginning after June
15, 2005.  Adoption of this  statement is not expected to materially  impact the
Company's consolidated results of operations, cash flows or financial position.

  SFAS No. 153

     In December  2004,  FASB issued SFAS,  No. 153  "Exchanges  of  Nonmonetary
Assets."  This  standard  eliminates  the  exception  in  APB  Opinion  No.  29,
"Accounting for Nonmonetary  Transactions" for nonmonetary  exchanges of similar
productive  assets and  replaces it with a general  exception  for  exchanges of
nonmonetary assets that do not have commercial substance.  It requires exchanges
of productive assets to be accounted for at fair value, rather than at carryover
basis,  unless (1) neither the asset  received nor the asset  surrendered  has a
fair value that is determinable  within reasonable limits or (2) the transaction
lacks commercial  substance (as defined).  A nonmonetary exchange has commercial
substance  if the  future  cash  flows of the  entity  are  expected  to  change
significantly as a result of the exchange.

     The new standard  will not apply to the transfers of interests in assets in
exchange for an interest in a joint venture and amends SFAS No. 66,  "Accounting
for Sales of Real  Estate" to clarify  that  exchanges  of real  estate for real
estate should be accounted for under APB Opinion No. 29. It also amends SFAS No.
140, to remove the  existing  scope  exception  relating to  exchanges of equity
method  investments for similar productive assets to clarify that such exchanges
are within the scope of SFAS No. 140 and not APB Opinion No. 29. SFAS No. 153 is
effective for nonmonetary asset exchanges  occurring in fiscal periods beginning
after June 15, 2005.  Adoption of this  statement is not expected to  materially
impact the Company's consolidated results of operations, cash flows or financial
position.

  SFAS No. 154

     In May 2005,  FASB  issued  SFAS No.  154,  "Accounting  Changes  and Error
Corrections." This Statement replaces APB Opinion No. 20, "Accounting  Changes,"
and FASB Statement No. 3,  "Reporting  Accounting  Changes in Interim  Financial
Statements,"  and changes the  requirements for the accounting for and reporting
of a change in  accounting  principle.  SFAS No. 154  applies  to all  voluntary
changes in accounting  principle.  Opinion No. 20 previously  required that most
voluntary  changes in  accounting  principle be  recognized  by including in net
income for the period of the change the cumulative effect of changing to the new
accounting principle.  SFAS No. 154 requires retrospective  application to prior
periods' financial statements of changes in accounting  principle,  unless it is
impracticable to determine either the period-specific  effects or the cumulative
effect of the change.  When it is  impracticable  to  determine  the  cumulative
effect of applying a change in accounting  principle to all prior periods,  SFAS
No. 154  requires  that the new  accounting  principle  be applied as if it were
adopted prospectively from the earliest date practicable.

     SFAS No. 154 also requires that a change in depreciation,  amortization, or
depletion  method for  long-lived,  nonfinancial  assets be  accounted  for as a
change in accounting estimate effected by a change in accounting principle. SFAS
No. 154 is  effective  beginning  after  December  15,  2005.  Adoption  of this
statement  is not  expected  to  materially  impact the  Company's  consolidated
results of operations, cash flows or financial position.

  EITF Issue No. 03-13

     At the November 2004 EITF meeting,  the final consensus was reached on EITF
Issue No. 03-13,  "Applying the Conditions in Paragraph 42 of FASB Statement No.
144 in Determining  Whether to Report  Discontinued  Operations."  This Issue is
effective  prospectively for disposal transactions entered into after January 1,
2005,  and provides a model to assist in evaluating  (a) which cash flows should
be  considered  in the  determination  of  whether  cash  flows of the  disposal
component  have been or will be  eliminated  from the ongoing  operations of the
entity and (b) the types of continuing  involvement that constitute  significant
continuing involvement in the operations of the disposal component.  The Company
has applied the model  outlined in EITF Issue No. 03-13 in its evaluation of the
September  2004 sale of the  Canadian  and Rockies oil and gas  reserves and the
July 2005 sale of its  remaining  oil and gas reserves and the July 2005 sale of
the Saltend  facility in  determining  whether or not the cash flows  related to
these  components  have been or will be permanently  eliminated from the ongoing
operations of the Company.

3.   Strategic Initiative

     The Company's ability to capitalize on growth  opportunities and to service
the debt it incurred to construct  and operate its current fleet of power plants
is dependent on the continued  availability of capital on attractive  terms. The
availability of such capital in today's  environment is uncertain.  To date, the
Company  has  obtained  cash  from  its  operations;   borrowings  under  credit
facilities;  issuances of debt, equity, trust preferred securities,  convertible
debentures  and  contingent  convertible  notes;  proceeds  from  sale/leaseback
transactions;  sale or partial sale of certain assets;  prepayments received for
power sales;  contract  monetizations;  and project financings.  The Company has
utilized this cash to fund its operations,  service,  or repay or refinance debt
obligations,   fund   acquisitions,   develop  and  construct  power  generation
facilities,  finance  capital  expenditures,  support  its  hedging,  balancing,
optimization  and  trading  activities,  and meet its other  cash and  liquidity
needs.

     Access to capital has been  restricted  since late 2001.  While the Company
has been  able to  access  the  capital  and  bank  credit  markets  in this new
environment,  it has been on significantly  different terms than in the past. In
particular,  the senior  working  capital  facilities  and term loan  financings
entered into,  and the majority of the debt  securities  offered and sold by the
Company in this period have been secured by certain of the Company's  assets and
subsidiary equity  interests.  The Company has also provided security to support
prepaid commodity transactions.  In the aggregate,  the average interest rate on
the  Company's  new debt  instruments,  especially on debt incurred to refinance
existing debt, has been higher. The terms of financing  available now and in the
future may not be attractive to the Company.  The timing of the  availability of
capital is uncertain and is dependent,  in part, on market  conditions  that are
difficult to predict and are outside of the Company's control.

     At June 30,  2005,  the  Company  had  negative  working  capital of $555.1
million  which is due to $2.2  billion of debt,  preferred  interests  and notes
payable being due within the next twelve months, $1.6 billion of which is due by
December 31, 2005. In addition, the Company has significant near-term maturities
of debt in periods  subsequent to the next twelve months (see Note 7 for further
discussion of future maturities and other matters impacting the Company's debt).
Cash flow used in operating  activities  during the six-month  period ended June
30, 2005 was $239.3  million and is expected to continue to be negative at least
for the near  term and  possibly  longer.  On June 30,  2005,  our cash and cash
equivalents  on hand totaled  $0.6 billion (see Note 2). The current  portion of
restricted cash totaled $1.0 billion, including $402.5 million which was used to
redeem the HIGH TIDES III preferred securities in July of 2005.

     Satisfying all obligations  under the Company's  outstanding  indebtedness,
and funding  anticipated capital  expenditures and working capital  requirements
for the next twelve months and potentially  thereafter presents the Company with
several challenges as cash requirements (including refinancing  obligations) are
expected to exceed the sum of cash on hand  permitted to be used to satisfy such
requirements and cash from operations.  Accordingly,  the Company has in place a
strategic  initiative which includes  possible sales or monetizations of certain
of its assets.  Whether the Company will have sufficient  liquidity will depend,
in part,  on the success of that  program.  No  assurance  can be given that the
program will be successful.  If it is not  successful,  additional  asset sales,
refinancings,  monetizations  and  other  items  beyond  those  included  in the
strategic  initiative  would  likely  need  to be  taken,  depending  on  market
conditions. The Company's ability to reduce debt will also depend on its ability
to repurchase debt securities through open market transactions and the principal
amount of debt able to be repurchased  will be contingent upon market prices and
other factors. Even if the program is successful, there can be no assurance that
the Company  will be able to continue  work on its projects in  development  and
suspended  construction that have not successfully  obtained project  financing,
and it could  possibly  incur  substantial  impairment  losses as a  result.  In
addition,  even if the  program  is  successful,  until  there  are  significant
sustained  improvements  in spark spreads,  the Company expects that it will not
have sufficient  cash flow from  operations to repay all of its  indebtedness at
maturity or to fund its other liquidity  needs. The Company expects that it will
need to extend or refinance  all or a portion of its  indebtedness  on or before
maturity.  While the Company  currently  believes  that it will be successful in
repaying,  extending  or  refinancing  all  of  its  indebtedness  on or  before
maturity,  there can be no  assurance  that it will be able to do so or that the
terms of any such refinancing will be attractive.

     The Company endeavors to improve its financial  strength.  On May 25, 2005,
the Company announced a strategic initiative aimed at:

     o    Optimizing  the value of the Company's core North American power plant
          portfolio  by selling  certain  power and natural gas assets to reduce
          debt and lower  annual  interest  cost,  and to increase  cash flow in
          future periods. At June 30, 2005, the Company had pending asset sales,
          including  the  sale of  Saltend  in the  United  Kingdom  (which  was
          completed  July 28,  2005),  its  interests in up to eight  additional
          gas-fired  power  plants  in the  United  States  (two of  which  were
          completed in July and August 2005) and its  remaining  oil and natural
          gas assets (which was completed on July 7, 2005). See Notes 8 and 15.

     o    Taking  actions  to  decrease  operating  and  maintenance  costs  and
          lowering  fuel  costs to  improve  the  operating  performance  of the
          Company's  power  plants,  which would boost  operating  cash flow and
          liquidity.   In  addition,  the  Company  is  considering  temporarily
          shutting  down certain  power plants with  negative  cash flow,  until
          market  conditions  warrant starting back up, to further reduce costs.
          See Note 15 for a discussion  of the  restructuring  of certain of the
          Company's LTSAs.

     o    Reducing  Calpine's  collateral   requirements.   The  Company  and  a
          financial  institution  are  discussing  a business  venture  that the
          Company  anticipates  would lower collateral  requirements and enhance
          the Company's third party customer business.

     o    Reducing total debt through the initiatives  listed above by more than
          $3  billion  by the end of 2005  from debt  levels at March 31,  2005,
          which the  Company  estimates  would  provide  $275  million of annual
          interest  savings.  As noted above,  the cash and other  consideration
          needed to reduce  debt by that amount will be a function of the market
          value  of debt  repurchased  in open  market  transactions  and  other
          factors.

     As a complement to the Company's strategic  initiative program, the Company
desires to expand its third party combustion  turbine component parts and repair
and maintenance services business.

     While there can be no  assurance  that the Company  will be  successful  in
achieving  the goals of this  strategic  initiative  and meeting  our  financing
obligations,  progress  in  the  quarter  ended  June  30,  2005,  included  the
following:

     o    Repurchased  in open market  transactions  $479.8 million in principal
          amount of its outstanding debt. The securities,  which were trading at
          a discount to par value,  were  repurchased for $337.9 million in cash
          plus accrued interest. The Company recorded a $137.5 million gain as a
          result of these  repurchases  after write-off of unamortized  deferred
          financing  costs  and  unamortized  discounts.  See  Note  7 for  more
          information.

     o    Received  funding for Metcalf's  $155.0  million  offering of 5.5-Year
          Redeemable Preferred Shares and five-year,  $100.0 million Senior Term
          Loan. A portion of the net  proceeds  was used to repay $50.0  million
          outstanding  on the  original  Metcalf  project  financing,  with  the
          remaining  net  proceeds  to be used  as  permitted  by the  company's
          existing indentures. See Note 7 for more information.

     o    Received funding for its $123.1 million,  non-recourse project finance
          facility to complete the  construction of the 79.9-MW  Bethpage Energy
          Center  3.  Approximately  $55  million  of the  funding  was  used to
          reimburse  the  Company  for costs  spent to date on the  project.  An
          additional  amount of $11.2  million  will be  released to the Company
          upon satisfying certain conditions.  The balance of funds will be used
          for transaction  expenses,  the final completion of the project and to
          fund certain reserve accounts.

     o    Issued $650.0 million in principal amount of 2015 Convertible Notes in
          June  2005.  The  Company,  in July  2005,  used a portion  of the net
          proceeds to redeem the $517.5  million in principal  amount of 5% HIGH
          TIDES III preferred  securities,  of which $115.0  million was held by
          the Company. The Company used the remaining net proceeds to repurchase
          a portion of the  outstanding  principal  amount of its 8 1/2%  Senior
          Notes due 2011. See Notes 7 and 11 for more information.

     o    Repurchased  $94.3  million in  principal  amount at  maturity of 2014
          Convertible  Notes in  exchange  for 27.5  million  shares of  Calpine
          common stock.  The Company  recorded a pre-tax loss of $7.9 million on
          the  exchange,   which   includes  the  write-off  of  the  associated
          unamortized  deferred  financing costs and unamortized  original issue
          discount. See Note 7 for more information.

     Additionally,  subsequent  to June 30,  2005,  the  Company  completed  the
following  transactions  (see Note 15 for a  further  discussion  of  subsequent
events):

     o    Sold  all of its  remaining  domestic  oil  and  gas  exploration  and
          production  properties and assets for $1.05 billion, less adjustments,
          transaction fees and expenses,  and less  approximately $75 million to
          reflect  the value of  certain  oil and gas  properties  for which the
          Company was unable to obtain consents to assignment  prior to closing.
          The  Company  expects to receive  the  remaining  consents in the near
          future.

     o    Completed the sale of Saltend, a 1,200-MW power plant located in Hull,
          England,  generating  total gross proceeds of $862.5 million.  Of this
          amount,  $647.1 million was used to redeem the $360.0 million Two-Year
          Redeemable  Preferred Shares issued by the Company's  Calpine Jersey I
          subsidiary  on October 26,  2004,  and the $260.0  million  Redeemable
          Preferred Shares issued by the Company's  Calpine Jersey II subsidiary
          on January 31, 2005,  including interest and early termination fees of
          $16.3 million and $10.8 million, respectively. As described further in
          Note 12, certain bondholders filed a lawsuit concerning the use of the
          remaining proceeds from the sale of Saltend.

     o    Sold its 50%  interest  in the 175-MW  Grays  Ferry  power plant to an
          affiliate of TNAI for $37.4 million. Previously, in the second quarter
          of 2005,  the Company  recorded an impairment  charge of $18.5 million
          related to its interest.

     o    Completed the sale of its 156-MW Morris power plant for $84.5 million.
          Previously,  in the second  quarter of 2005,  the  Company  recorded a
          $106.2 million impairment charge related to this facility.

     o    Purchased  $138.9  million of its First Priority Notes under the terms
          of a tender offer.

     o    Announced a 15-year  Master  Products and Services  Agreement with GE,
          which is expected to lower operating costs in the future.  As a result
          of nine GE LTSA cancellations during the quarter, the Company recorded
          $33.1 million in charges.

     o    Signed an  agreement  with Siemens  Westinghouse  to  restructure  the
          long-term  relationship,  which the  Company  expects  will  afford it
          additional flexibility to self-perform maintenance work in the future.

     The Company is  considering  the sale of  additional  assets  including the
Ontelaunee  Energy  Center  and  the  Philadelphia   Water  Works  Plant.  These
additional sales could lead to additional  material impairment charges or losses
upon sale.

     The sale of assets  to  reduce  debt and  lower  annual  interest  costs is
expected to  materially  lower the  Company's  revenues,  spark spread and gross
profit  (loss)  and the final mix of assets  actually  sold will  determine  the
degree of impact on operating  results.  While lowering debt, the accomplishment
of the strategic  initiative  program, in and of itself, will likely not lead to
improvement  in certain  measures of interest  and  principal  coverage  without
significant  improvement in market  conditions.  The amount of offsetting future
interest  savings will be a function of the principal amunt of debt  repurchased
and the amount  that the  Company  will spend to reduce  debt will depend on the
market price of such debt and other factors , and the final net future  earnings
impact of the initiatives is still uncertain.

4.   Available-for-Sale Debt Securities

     On September 30, 2004, the Company  repurchased $115.0 million in par value
of HIGH TIDES III preferred  securities for cash of $111.6  million.  Due to the
deconsolidation  of Calpine  Capital Trust III, the issuer of the HIGH TIDES III
preferred  securities,upon  the adoption of FIN 46 as of December 31, 2003,  and
the terms of the  underlying  convertible  debentures  issued by  Calpine to the
Trust, the repurchased  HIGH TIDES III preferred  securities could not be offset
against  the  convertible  subordinated  debentures  and  are  accounted  for as
available-for-sale  securities.  On July 13,  2005,  the Company  completed  the
redemption of all of the outstanding HIGH TIDES III preferred  securities and of
the underlying convertible debentures. Accordingly, the HIGH TIDES III preferred
securities repurchased by the Company are no longer outstanding. See Note 15 for
more  information.  The  Company  has  classified  the HIGH TIDES III  preferred
securities held by the Company at June 30, 2005, in the  Consolidated  Condensed
Balance Sheet as "Other  current  assets" at fair market value at June 30, 2005,
with the difference from their repurchase price recorded in OCI (in thousands):

<FN>
(1)  There were a total of six consolidated  projects in active  construction at
     June 30, 2005.  Additionally,  the Company has one project that is recorded
     in unconsolidated investments and is not included in the table above.
</FN>


     Construction  in Progress -- CIP is  primarily  attributable  to  gas-fired
power projects under construction including prepayments on gas and steam 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.

     Projects  in  Active   Construction  --  Two  of  the  projects  in  active
construction  came on line in July 2005 and the other  four  projects  in active
construction  are projected to come on line from November 2005 to November 2007.
These projects will bring on line  approximately  1,827 MW of base load capacity
(2,058 MW with  peaking  capacity).  Interest  and other  costs  related  to the
construction  activities necessary to bring these projects to their intended use
are being  capitalized.  At June 30, 2005, the total projected costs to complete
these  projects was $633.5  million and the estimated  funding  requirements  to
complete  these  projects,  net of  expected  project  financing  proceeds,  was
approximately $23.7 million.

     Projects in Suspended  Construction -- Work and  capitalization of interest
on the three  projects in suspended  construction  has been suspended or delayed
due  to  current  market   conditions.   These  projects  would  bring  on  line
approximately  1,769 MW of base load capacity (2,035 MW with peaking  capacity).
The Company expects to finance the remaining  $338.0 million  projected costs to
complete these projects if and when construction resumes.

     Projects  in  Advanced  Development  -- There were 12  projects in advanced
development at June 30, 2005.  These projects would bring on line  approximately
4,976 MW of base load capacity  (6,335 MW with peaking  capacity).  Interest and
other  costs  related to the  development  activities  necessary  to bring these
projects  to  their   intended   use  are  being   capitalized.   However,   the
capitalization  of  interest  has been  suspended  on four  projects  for  which
development  activities are  substantially  complete but  construction  will not
commence until a PPA and financing are obtained. One of the projects in advanced
development,  Inland Empire Energy Center,  was sold to a third party subsequent
to June 30, 2005.  See Note 15 for more  information  regarding  this sale.  The
estimated  cost to complete  the  projects in  advanced  development  other than
Inland Empire Energy Center,  was  approximately  $2.9 billion at June 30, 2005.
The  Company's  current  plan is to  finance  these  project  costs  as PPAs are
arranged.

     Suspended   Development   Projects  --  Due  to  current   electric  market
conditions,  the Company has ceased  capitalization  of  additional  development
costs and interest expense on three development  projects on which work has been
suspended.  Capitalization  of costs may  recommence  as work on these  projects
resumes,  if certain milestones and criteria are met indicating that it is again
highly probable that the costs will be recovered through future  operations.  As
is true for all  projects,  the suspended  projects are reviewed for  impairment
whenever  there is an  indication  of potential  reduction  in a project's  fair
value.  Further,  if it is  determined  that it is no longer  probable  that the
projects will be completed and all capitalized  costs  recovered  through future
operations,  the carrying  values of the projects would be written down to their
recoverable  value.  During  the  quarter  ended  June  30,  2005,  the  Company
determined  to  abandon  its  development  efforts on three of six  projects  is
suspended  development  and recorded  $45.5 million to the "Project  development
expense" line item of the Consolidated  Condensed Statements of Operations.  The
three  remaining   projects  in  suspended   development  would  bring  on  line
approximately 865 MW of base load capacity (1,055 MW with peaking capacity). The
estimated cost to complete these projects is approximately $563.1 million.

     Projects  in Early  Development  -- Costs  for  projects  that are in early
stages of development are capitalized  only when it is highly probable that such
costs  are  ultimately   recoverable  and  significant  project  milestones  are
achieved.  Until then all costs,  including  interest costs,  are expensed.  The
projects in early  development with capitalized costs relate to two projects and
include geothermal drilling costs and equipment purchases.

     Other  Capital  Projects -- Other  capital  projects  primarily  consist of
enhancements  to operating power plants,  pipelines and geothermal  resource and
facilities development, as well as software developed for internal use.

     Unassigned  Equipment -- As of June 30, 2005, the Company had made progress
payments on four turbines and other  equipment with an aggregate  carrying value
of $67.5 million.  This unassigned  equipment is classified on the  Consolidated
Condensed Balance Sheet as "Other assets" because it is not assigned to specific
development and construction projects. The Company is holding this equipment for
potential use on future  projects.  It is possible that some of this  unassigned
equipment may eventually be sold,  potentially in combination with the Company's
engineering and construction services.

     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
CIP,  certain   pipelines  under   development,   geothermal   properties  under
construction,  certain costs for information systems  development,  construction
costs  related  to   unconsolidated   investments   in  power   projects   under
construction,  advanced stage development costs, as well as such above mentioned
assets classified as held for sale. For the three months ended June 30, 2005 and
2004, the total amount of interest  capitalized  was $64.2  million,  and $102.2
million, respectively,  including $11.8 million and $15.4 million, respectively,
of interest  incurred on funds borrowed for specific  construction  projects and
$52.4 million and $86.8 million,  respectively,  of interest incurred on general
corporate funds used for the advanced  stages of development  and  construction.
For the six months  ended June 30, 2005 and 2004,  the total  amount of interest
capitalized was $134.4 million and $210.7 million, respectively, including $22.5
million and $34.0 million,  respectively, of interest incurred on funds borrowed
for  specific  construction  projects  and $111.8  million  and $176.7  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 decrease in the amount of interest capitalized during the
three  and  six  months  ended  June  30,  2005,   reflects  the  completion  of
construction  for  several  power  plants,  the  suspension  of  certain  of the
Company's  development  and  construction  projects,  and  a  reduction  in  the
Company's development and construction program in general.

     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 of interest  incurred on general  corporate  funds are the Company's
Senior  Notes and term loans as well as the secured  working  capital  revolving
credit facility.

     Impairment  Evaluation -- All  construction  and  development  projects and
unassigned  turbines are reviewed for impairment whenever there is an indication
of potential reduction in fair value. Equipment assigned to such projects is not
evaluated for  impairment  separately,  as it is integral to the assumed  future
operations of the project to which it is assigned.  If it is determined  that it
is no longer  probable that the projects  will be completed and all  capitalized
costs recovered through future  operations,  the carrying values of the projects
would be written down to the recoverable value in accordance with the provisions
of SFAS No. 144. The Company  reviews its  unassigned  equipment  for  potential
impairment based on probability-weighted alternatives of utilizing the equipment
for future  projects versus selling the equipment.  Utilizing this  methodology,
the  Company  does not  believe  that the  equipment  held for use is  impaired.
However,  during the six months ended June 30, 2004, the Company recorded to the
"Equipment  cancellation and impairment cost" line of the Consolidated Condensed
Statement of Operations  $2.4 million in net losses in connection with equipment
cancellations,  and it may incur further  losses should it decide to cancel more
equipment contracts or sell unassigned equipment in the future. In the event the
Company  were  unable to obtain  PPAs or project  financing  and  suspension  or
abandonment  were to result,  the Company  could suffer  substantial  impairment
losses on such projects.

     Based on an evaluation  of the  probability-weighted  expected  future cash
flows  (considering  continuing  to own and  operate  the Morris  Power Plant or
consummating  the sale  transaction  with Diamond) at June 30, 2005, the Company
determined that the carrying  amount of the facility was impaired.  As a result,
during the quarter ended June 30, 2005, the Company recorded to the "Power plant
impairment" line of the Consolidated  Condensed Statement of Operations a $106.2
million impairment  charge.  Subsequent to June 30, 2005, the Company entered in
an  agreement  to  sell  the  facility,  located  in  Illinois  to  Diamond  for
approximately  $84.5 million in cash.  See Note 15 for more  information on this
sale.

     See Note 6 for a discussion of the impairment charge in connection with the
Grays Ferry  power plant and Note 3 for a  discussion  of  potential  additional
material impairment charges arising from the possible sale of additional assets.

6.   Unconsolidated Investments

     The Company's  unconsolidated  investments  are integral to its operations.
The Company's joint venture investments were evaluated under FASB Interpretation
No. 46  "Consolidation  of Variable Interest Entities - An Interpretation of ARB
51" as amended,  to determine  which, if any,  entities were VIEs. Based on this
evaluation,  the Company determined that Acadia PP, Valladolid III Energy Center
(Valladolid), Grays Ferry, Whitby and AELLC were VIEs, in which the Company held
a significant variable interest.  However, all of the entities except for Acadia
PP met the  definition  of a  business  and  qualified  for the  business  scope
exception  provided in paragraph  4(h) of FIN 46-R,  and  consequently  were not
subject to the VIE  consolidated  model.  Further,  based on a  qualitative  and
quantitative  assessment of the expected  variability  in Acadia PP, the Company
was not the Primary Beneficiary.  Consequently, the Company continues to account
for its joint venture  investments  in accordance  with APB Opinion No. 18, "The
Equity  Method  of  Accounting  For  Investments  in Common  Stock"  and FIN 35,
"Criteria for Applying the Equity Method of Accounting for Investments in Common
Stock (An Interpretation of APB Opinion No. 18)." However, in the fourth quarter
of 2004,  the  Company  changed  from the  equity  method to the cost  method to
account for its investment in AELLC as discussed below.

     Acadia  PP  is  the  owner  of a  1,210-MW  electric  wholesale  generation
facility,  Acadia  Energy  Center,  located in Louisiana  and is a joint venture
between the Company and Cleco Corporation. The Company's involvement in this VIE
began  upon  formation  of the  entity  in March  2000.  The  Company's  maximum
potential  exposure to loss from its equity  investment  at June 30,  2005,  was
limited to the book value of its  investment of  approximately  $216.1  million,
plus any loss that may accrue  from a tolling  agreement  between  Acadia PP and
CES.

     Compania de  Generacion  Valladolid S. de R.L. de C.V.  partnership  is the
owner of Valladolid III Energy Center, a 525-MW, natural gas-fired energy center
currently under construction at Valladolid, Mexico in the Yucatan Peninsula. The
facility will deliver  electricity to CFE under a 25-year power sales agreement.
The project is a joint  venture  between the Company,  Mitsui,  and Chubu,  both
headquartered  in Japan.  The Company  owns 45% of the entity  while  Mitsui and
Chubu each own 27.5%. Construction began in May 2004 and the project is expected
to achieve  commercial  operation in the summer of 2006.  The Company's  maximum
potential  exposure to loss at June 30,  2005,  was limited to the book value of
its investment of approximately $80.7 million.

     Grays  Ferry  is the  owner of a 175-MW  gas-fired  cogeneration  facility,
located  in  Pennsylvania  and  is a  joint  venture  between  the  Company  and
Trigen-Schuylkill Cogeneration, Inc. The Company's involvement in this VIE began
with its  acquisition of the  independent  power  producer,  Cogen America,  now
called  Calpine Cogen,  in December 1999. The Grays Ferry joint venture  project
was part of the portfolio of assets owned by Cogen America. On July 8, 2005, the
Company  completed the sale of the Grays Ferry power plant, in which it held 50%
interest,  for $37.4 million.  The Company recorded an $18.5 million  impairment
charge in the quarter  ended June 30, 2005,  due to the  imminent  sale of Grays
Ferry. Net proceeds from the sale of Grays Ferry will be used to reduce debt and
as permitted by the Company's indentures.  This transaction did not qualify as a
discontinued  operation  under  the  guidance  of SFAS 144,  which  specifically
excludes equity method investments from its scope, unless the investment is part
of a larger disposal group.

     Whitby is the owner of a 50-MW gas-fired cogeneration facility,  located in
Ontario,  Canada and is a joint venture between the Company and a privately held
enterprise.  The Company's involvement in this VIE began with its acquisition of
a portfolio  of assets from  Westcoast  in September  2001,  which  included the
Whitby joint venture project.  The Company's maximum potential  exposure to loss
at  June  30,  2005,  was  limited  to  the  book  value  of its  investment  of
approximately $42.6 million.

     AELLC  is  the  owner  of  a  136-MW   gas-fired   cogeneration   facility,
Androscoggin Energy Center,  located in Maine and is a joint venture between the
Company, and affiliates of Wisvest Corporation and IP. The Company's involvement
in this VIE  began  with its  acquisition  of the  independent  power  producer,
SkyGen,  in October  2000.  The AELLC joint venture was part of the portfolio of
assets owned by SkyGen. On November 3, 2004, a jury verdict was rendered against
AELLC in a breach of contract  dispute  with IP. The Company  recorded its $11.6
million  share of the award amount in the third quarter of 2004. On November 26,
2004,  AELLC  filed a  voluntary  petition  for relief  under  Chapter 11 of the
Bankruptcy Code. As a result of the bankruptcy, the Company has lost significant
influence  and  control  of the  project  and has  adopted  the cost  method  of
accounting  for its  investment  in AELLC.  Also,  in December  2004 the Company
determined that its investment in AELLC,  including outstanding notes receivable
and O&M receivable, was impaired and recorded a $5.0 million impairment reserve.
The facility had  third-party  debt of $63.4 million  outstanding as of December
31, 2004,  primarily  consisting of $60.3 million in construction debt. The debt
was  non-recourse to Calpine  Corporation.  On April 12, 2005,  AELLC sold three
fixed-price gas contracts to Merrill Lynch Commodities  Canada,  ULC, and used a
portion of the proceeds to pay down its remaining  construction debt. As of June
30, 2005, the facility had  third-party  debt  outstanding of $3.1 million.  See
Note 12 for an update on this investment.

     The following  investments are accounted for under the equity method except
for Androscoggin Energy Center, which is accounted for under the cost method (in
thousands):

(1)  Whitby  is  owned  50% by  the  Company  but a 70%  economic  share  in the
     Company's  ownership  interest  has been  effectively  transferred  to CPLP
     through a loan from CPLP to the Company's entity which holds the investment
     interest in Whitby.

(2)  Excludes certain Notes Receivable.

     The third-party debt on the books of the unconsolidated  investments is not
reflected on the Company's  balance  sheet.  At June 30, 2005,  and December 31,
2004,  third party  investee debt was  approximately  $200.2  million and $133.9
million,  respectively.  Of these  amounts,  $3.1  million  and  $63.4  million,
respectively,  relate to the Company's  investment in AELLC,  for which the cost
method of  accounting  was used. In addition,  $45.2 million and $44.3  million,
respectively,  relate to the  Company's  investment  in Grays  Ferry,  which the
Company  sold  subsequent  to June 30,  2005.  Based on the  Company's  pro rata
ownership  share  of each of the  investments,  the  Company's  share  would  be
approximately $84.8 million and $46.6 million for the respective periods.  These
amounts include the Company's share for AELLC of $1.0 million and $20.5 million,
respectively,   and  for  Grays  Ferry  of  $22.6  million  and  $22.2  million,
respectively.  All such debt is  non-recourse  to the  Company.  The increase in
investee debt between  periods is primarily due to borrowings for the Valladolid
III Energy Center currently under construction.

Related-Party Transactions with Unconsolidated Investments

     The  Company  and  certain of its equity and cost  method  affiliates  have
entered into various  service  agreements with respect to power projects and oil
and gas  properties.  Following is a general  description of each of the various
agreements:

     O&M  Agreements  -- The  Company  operates  and  maintains  the  Acadia and
Androscoggin Energy Centers.  This includes routine  maintenance,  but not major
maintenance,  which is typically  performed under  agreements with the equipment
manufacturers.  Responsibilities  include  development  of  annual  budgets  and
operating plans.  Payments include  reimbursement of costs,  including Calpine's
internal personnel and other costs, and annual fixed fees.

     Construction   Management  Services  Agreements  --  The  Company  provides
construction  management services to the Valladolid III Energy Center.  Payments
include  reimbursement of costs,  including the Company's internal personnel and
other costs.

     Administrative  Services  Agreements -- The Company handles  administrative
matters such as bookkeeping for certain unconsolidated  investments.  Payment is
on a cost  reimbursement  basis,  including  Calpine's  internal costs,  with no
additional fee.

     Power Marketing  Agreements -- Under  agreements with AELLC, CES can either
market  the  plant's  power  as the  power  facility's  agent  or buy the  power
directly.  Terms of any direct  purchase  are to be agreed  upon at the time and
incorporated into a transaction  confirmation.  Historically,  CES has generally
bought the power from the power facility rather than acting as its agent.

     Gas  Supply  Agreement  --  CES  can  be  directed  to  supply  gas  to the
Androscoggin  Energy  Center  facility  pursuant  to  transaction  confirmations
between  the  facility  and CES.  Contract  terms are  reflected  in  individual
transaction confirmations.

     The power marketing and gas supply  contracts with CES are accounted for as
either purchase and sale arrangements or as tolling arrangements.  In a purchase
and sale arrangement, title and risk of loss associated with the purchase of gas
is transferred  from CES to the project at the gas delivery  point. In a tolling
arrangement,  title to fuel provided to the project does not  transfer,  and CES
pays the project a capacity and a variable  fee based on the  specific  terms of
the power  marketing  and gas supply  agreements.  In addition to the  contracts
specified above,  CES maintains two tolling  agreements with the Acadia facility
which are  accounted  for as leases.  All of the other power  marketing  and gas
supply contracts are accounted for as purchases and sales.

     The  related  party  balances as of June 30, 2005 and  December  31,  2004,
reflected in the accompanying  Consolidated  Condensed  Balance Sheets,  and the
related party transactions for the three and six months ended June 30, 2005, and

7.   Debt

     Issuance of Mandatorily  Redeemable Preferred Interest -- On June 20, 2005,
the  Company's  indirect  subsidiary  Metcalf,  consummated  the sale of  $155.0
million of 5.5-Year  Redeemable  Preferred Shares priced at LIBOR plus 900 basis
points.  The proceeds  will  ultimately  be used as  permitted by the  Company's
existing  bond  indentures.  Concurrent  with  the  closing  of the  sale of the
Redeemable  Preferred Shares,  Metcalf entered into a five-year,  $100.0 million
senior term loan at LIBOR plus 300 basis  points.  Proceeds from the senior term
loan were used to  refinance  all  outstanding  indebtedness  under the existing
$100.0 million non-recourse  construction credit facility. The remaining portion
will be  used to pay  fees  and  expenses  related  to the  transaction,  and as
otherwise  permitted by the Company's  existing bond indentures.  The Redeemable
Preferred  Shares  were  offered  in the  United  States in a private  placement
transaction pursuant to Regulation D under the Securities Act.

     Senior Note Repurchases -- During the three months ended June 30, 2005, the
Company  repurchased  Senior Notes in open market  transactions  totaling $479.8
million in principal. The Company repurchased the Senior Notes for cash totaling
$337.9 million plus accrued interest as follows (in thousands):

     For the three months ended June 30, 2005, the Company recorded an aggregate
pre-tax gain of $129.2 million on the above debt repurchases and equity for debt
exchange  after  the  write-off  of  unamortized  deferred  financing  costs and
unamortized discounts.

     3(a)(9)  Equity for Debt Exchange -- On June 28, 2005,  the Company  issued
27.5  million  unregistered  shares of its common  stock,  par value  $.001,  in
exchange  for $94.3  million in aggregate  principal  amount at maturity of 2014
Convertible  Notes pursuant to the exemption  afforded by Section  3(a)(9) under
the Securities Act. At June 30, 2005,  approximately $641.7 million in aggregate
principal amount at maturity of the 2014 Convertible  Notes remain  outstanding.
No commission or other  remuneration was paid or given,  directly or indirectly,
for  soliciting  such  exchange.  The  Company  recorded a pre-tax  loss of $7.9
million on the exchange,  which includes write-off of the associated unamortized
deferred financing cost and unamortized original issue discount.

     Issuance of Contingent  Convertible  Senior Notes -- On June 23, 2005,  the
Company closed its public  offering of $650 million of 2015  Convertible  Notes.
The Company used a portion of the net proceeds to repurchase  $302.5  million of
the outstanding  principal  amount of its 8 1/2% Senior Notes due 2011 (included
in Senior Notes  repurchase  amounts above).  The Company used the remaining net
proceeds of $402.5 million  towards the redemption in full of its HIGH TIDES III
preferred  securities in July 2005.  See Note 15 for discussion of the Company's
redemption of its HIGH TIDES III preferred  securities and related redemption of
the  underlying  convertible  debentures  payable to Calpine  Capital  Trust III
classified as a current liability as of June 30, 2005.

     The 2015 Convertible Notes are convertible,  at the option of holder,  into
cash  and  into  shares  of  Calpine  common  stock  at  a  conversion  rate  of
approximately 250 shares per $1,000 of principal  amount,  subject to applicable
adjustments.  Conversion is subject to a common stock price  condition where the
Company's  common stock is trading for at least 20 trading days in the period of
30  consecutive  trading  days ending on the last  trading  day of the  calendar
quarter  preceding the quarter in which the conversion  occurs at more than 120%
of the  conversion  price per share of the  common  stock in effect on that 30th
trading day.  Conversion  is also  subject to a trading  price  condition  where
during the five trading day period after any five consecutive trading day period
in which the trading price of $1,000  principal amount of the notes for each day
of such  five-day  period was less than 95% of the product of the  closing  sale
price of our common stock price on that day multiplied by the  conversion  rate.
Holders of the 2015  Convertible  Notes have a limited amount of time to convert
their notes once a  conversion  condition  has been  achieved.  Generally,  upon
conversion,  the  Company  is  required  to  deliver  the par  value of the 2015
Convertible Notes in cash and any additional  conversion value based upon market
prices for Calpine common stock at the time of conversion.  However,  in certain
bankruptcy-related  events of default the Company is required to deliver the par
value of the 2015  Convertible  Notes in Calpine common stock.  For a summary of
the  theoretical  maximum  additional  shares  potentially  issuable  under  our
contingent convertible notes, see Note 11.

     If a conversion  event were to occur under any of the Company's  contingent
convertible notes, the outstanding  principal amount due under these notes would
effectively  become  a  demand  note  during  the  conversion  window  and  such
outstanding  principal  amount would be reflected as a current  liability on the
Company's consolidated balance sheet. In addition, if a conversion event were to
occur and contingent convertible notes were tendered for conversion,  provisions
of the  Company's  outstanding  indentures  may require the Company to refinance
such tendered notes in order to comply with the conversion obligations.

     Closing of Project Finance Facility -- On June 30, 2005, the Company closed
on a $123.1 million,  non-recourse  project  finance  facility that will provide
funding to complete the  construction of the 79.9-MW Bethpage Energy Center 3 in
Hicksville,  N.Y. The Company has a 20-year power  contract with the Long Island
Power  Authority  for the power  plant's full  capacity  and related  energy and
ancillary  services  beginning in July 2005. The loan facility is comprised of a
20-year Senior Loan,  totaling $108.5 million,  at a fixed rate of 6.13%,  and a
15-year  Junior Loan of $14.6 million at a fixed rate of 7.94%.  The Company has
received  approximately  $55 million for costs spent to date on the project.  An
additional  amount  of  $11.2  million  will be  released  to the  Company  upon
satisfying  certain  conditions.  Remaining  amounts available under the project
loan facility will be used to fund transaction expenses, the final completion of
the project and certain reserve accounts.

     Annual Debt Maturities -- The annual principal  repayments or maturities of
notes  payable  and  borrowings  under lines of credit,  convertible  debentures
payable to  Calpine  Capital  Trust  III,  preferred  interests,  capital  lease
obligation,  CCFC I financing,  CalGen/CCFC  II financing,  construction/project

     See Note 15 for discussion of the Company's  redemption of its  outstanding
convertible  debentures  payable to Calpine  Capital  Trust III  classified as a
current liability as of June 30, 2005.

     Indenture  and Debt and  Lease  Covenant  Compliance  -- The  covenants  in
certain of the Company's debt agreements  currently  impose  restrictions on its
activities, including those discussed below:

     Certain of the  Company's  indentures  place  conditions  on its ability to
issue indebtedness if the Company's interest coverage ratio (as defined in those
indentures) is below 2:1.  Currently,  the Company's interest coverage ratio (as
so defined) is below 2:1 and,  consequently,  the Company generally would not be
allowed to issue new debt, except for (i) certain types of new indebtedness that
refinances or replaces  existing  indebtedness  and (ii)  non-recourse  debt and
preferred equity interests issued by the Company's  subsidiaries for purposes of
financing certain types of capital  expenditures,  including plant  development,
construction and acquisition costs and expenses.  In addition, if and so long as
the Company's  interest  coverage  ratio is below 2:1, the Company's  ability to
invest in  unrestricted  subsidiaries  and  non-subsidiary  affiliates  and make
certain other types of restricted payments will be limited. Moreover, certain of
the Company's indentures will prohibit any further investments in non-subsidiary
affiliates  if and  for so long  as its  interest  coverage  ratio  (as  defined
therein) is below 1.75:1 and, as of June 30, 2005, such interest  coverage ratio
was below 1.75:1.  The Company  currently does not expect this limitation on its
ability to make  investments  in  non-subsidiary  affiliates  to have a material
impact on its business.

     Certain of the Company's  indebtedness  issued in the last half of 2004 was
incurred  in  reliance  on  provisions  in  certain of its  existing  indentures
pursuant to which the Company is able to incur  indebtedness  if,  after  giving
effect  to the  incurrence  and the  repayment  of other  indebtedness  with the
proceeds  therefrom,  the Company's interest coverage ratio (as defined in those
indentures) is greater than 2:1. In order to satisfy the interest coverage ratio
requirement  in  connection  with certain debt  securities  issued in 2004,  the
proceeds of such issuances are required to be used to repurchase or redeem other
existing indebtedness. While the Company completed a substantial portion of such
repurchases  during the fourth quarter of 2004 and the first six months of 2005,
it is still in the process of completing the required  amount of repurchases and
expects to do so as soon as practicable.  While the amount that the Company will
be required to spend to repurchase the applicable  remaining principal amount of
such  indebtedness  will ultimately depend on the market prices of the Company's
outstanding  indebtedness  at the  time the  indebtedness  is  repurchased,  the
Company  estimates that, as of June 30, 2005, as adjusted for market  conditions
and  financial  covenant  calculations,  the Company  would be required to spend
approximately $184.0 million on additional repurchases in order to fully satisfy
this requirement.  If the market price of the Company's outstanding indebtedness
were to change  substantially  from current market  prices,  the amount that the
Company would be required to spend to repurchase  the same  principal  amount of
such  indebtedness  could be significantly  different from the amounts currently
estimated.  The principal amount of the indebtedness  required to be repurchased
has  been  classified  as  Senior  Notes,  current  portion,  on  the  Company's
Consolidated Condensed Balance Sheet as of June 30, 2005. Subsequent to June 30,
2005, the Company  satisfied a portion of such requirement such that, as of July
31, 2005, the Company's estimate,  adjusted as described above, is that it would
be required to spend approximately $182.0 million on additional repurchases.

     When the Company or one of its  subsidiaries  sells a significant  asset or
issues preferred equity, the Company's indentures generally require that the net
proceeds  of  the  transaction  be  used  to  make  capital  expenditures  or to
repurchase or repay certain types of indebtedness,  in each case within 365 days
of the  closing  date of the  transaction.  This  general  requirement  contains
certain customary  exceptions and, in the case of certain assets,  including the
gas  portion of the  Company's  oil and gas assets  sold in July 2005,  that are
defined as "designated assets" under some of the Company's indentures, there are
additional  provisions  that  apply  to the sale of these  assets  as  discussed
further  below.  In light of these  requirements,  and taking  into  account the
amount of capital expenditures  currently budgeted for the remainder of 2005 and
forecasted for 2006, the Company  anticipates  that subsequent to June 30, 2005,
it will need to use a total of approximately  $427.0 million of the net proceeds
from the three series of preferred equity issued by subsidiaries of the Company,
to repurchase or repay indebtedness.  Accordingly, this amount of long-term debt
has been  reclassified  as  Senior  Notes,  current  portion,  on the  Company's
Consolidated  Condensed  Balance Sheet as of June 30, 2005. The actual amount of
the net proceeds  that will be required to be used to  repurchase  or repay debt
will  depend  upon the actual  amount of the net  proceeds  that is used to make
capital  expenditures,  which  may be more or less  than  the  amount  currently
budgeted and/or forecasted.

     In addition, the net proceeds from the asset sales completed after June 30,
2005,  will  similarly be subject to the asset sale  provisions of the Company's
indentures,  and the Company  anticipates that, on the basis described above, in
connection  with the asset  sales that have been  completed  after June 30, 2005
(including  the sale of Saltend),  an additional  $343.1 million will need to be
used  to  make  qualifying  capital  expenditures  and/or  repurchase  or  repay
indebtedness.  As  described  further in Note 12,  certain  bondholders  filed a
lawsuit  concerning  the use of the proceeds  from the sale of the  Saltend.  In
connection  with  that  lawsuit,  the net  proceeds  from that  sale,  after the
redemption  of two series of  redeemable  preferred  securities,  are  currently
subject to an order of the Court in that matter  requiring  such  proceeds to be
held at or in the control of CCRC.

     As noted above, the Company's oil and gas assets were sold on July 7, 2005,
with the gas  component  of such sale  constituting  "designated  assets"  under
certain of the Company's  indentures.  These  indentures  require the Company to
make an offer to purchase  its First  Priority  Notes with the net proceeds of a
sale of  designated  assets not otherwise  applied in accordance  with the other
permitted uses under such indentures.  Accordingly, the Company made an offer to
purchase the First Priority Notes in June 2005. The offer to purchase expired on
July 8, 2005,  and the Company  purchased,  with proceeds of the sale of the gas
assets,  $138.9 million in principal amount of the First Priority Notes tendered
in connection with the offer to purchase.  The Company may use the remaining net
proceeds of $708.5  million  arising  from the sale of its gas assets to acquire
new natural gas and/or  geothermal  energy assets permitted to be acquired under
such  indentures,  and a portion of such  remaining  net  proceeds  have been so
applied. However, there can be no assurance that the Company would be successful
in identifying or acquiring any additional new assets on acceptable  terms or at
all. If the  Company  does not,  within 180 days of receipt of the net  proceeds
from  the sale of its gas  assets,  use all of the  remaining  net  proceeds  to
acquire such new assets,  and/or to repurchase or repay  (through open market or
privately negotiated transactions, tender offers or otherwise) any or all of the
$646.1 million  aggregate  principal  amount of First  Priority Notes  remaining
outstanding after consummation of the offer to purchase (either of which actions
the Company may, but is not  required,  to take),  then the Company will, to the
extent that the remaining net proceeds  from the sale exceed $50.0  million,  be
required under the terms of its Second Priority Secured Debt Instruments to make
an offer to purchase its outstanding second priority senior secured indebtedness
up to the amount of the remaining net proceeds.

     In  connection   with  several  of  our   subsidiaries'   lease   financing
transactions (Agnews, Geysers,  Pasadena, Broad River, RockGen, and South Point)
the insurance  policies we have in place do not comply in every respect with the
insurance  requirements  set forth in the financing  documents.  The Company has
requested  from the  relevant  financing  parties,  and is expecting to receive,
waivers of this  noncompliance.  While failure to have the required insurance in
place is listed in the financing documents as an event of default, the financing
parties may not  unreasonably  withhold their  approval of the Company's  waiver
request so long as the required insurance  coverage is not reasonably  available
or commercially feasible, and a report is delivered from the Company's insurance
consultant  to that effect.  The Company has  delivered  the required  insurance
consultant reports to the relevant  financing parties and therefore  anticipates
that the necessary waivers will be executed shortly.

     In connection with the  sale/leaseback  transaction of Agnews,  the Company
has  not  fully  complied  with  covenants  pertaining  to  the  operations  and
maintenance  agreement,  which noncompliance is technically an event of default.
The  Company  is in the  process of  addressing  this by  seeking  the  lessor's
approval to renew and extend the  operations and  maintenance  agreement for the
Agnews facility.

     In  connection  with the  sale/leaseback  transaction  of Calpine  Monterey
Cogeneration, Inc., the Company has not fully complied with covenants pertaining
to amendments  to gas and power  purchase  agreements,  which  noncompliance  is
technically  an event of default.  The  Company is in the process of  addressing
this by seeking a consent and waiver.

     Unrestricted  Subsidiaries -- The information in this paragraph is required
to be provided under the terms of the indentures and credit agreement  governing
the various tranches of the Company's Second Priority Secured Debt  Instruments.
The  Company  has  designated  certain  of  its  subsidiaries  as  "unrestricted
subsidiaries"  under the Second Priority Secured Debt Instruments.  A subsidiary
with "unrestricted"  status thereunder  generally is not required to comply with
the   covenants   contained   therein  that  are   applicable   to   "restricted
subsidiaries." The Company has designated Calpine Gilroy 1, Inc., Calpine Gilroy
2, Inc.  and Calpine  Gilroy  Cogen,  L.P. as  "unrestricted  subsidiaries"  for
purposes of the Second Priority Secured Debt Instruments.

8.   Discontinued Operations

     Set forth below are all of the  Company's  asset  disposals  by  reportable
segment that impacted the Company's  Consolidated Condensed Financial Statements
as of June 30, 2005,  due to  reclassifications  to  discontinued  operations to
reflect  the sales or "held for sale"  designations  of the assets sold or to be
sold.

Oil and Gas Production and Marketing

     On September 1, 2004, the Company,  together with Calpine Natural Gas L.P.,
a Delaware  limited  partnership,  completed the sale of its Rocky  Mountain gas
reserves that were primarily  concentrated in two geographic areas: the Colorado
Piceance  Basin  and the New  Mexico  San Juan  Basin.  Together,  these  assets
represented   approximately   120  Bcfe  of  proved  gas   reserves,   producing
approximately  16.3  Mmcfe per day of gas.  Under  the  terms of the  agreement,
Calpine received net cash payments of approximately $218.7 million, and recorded
a pre-tax gain of approximately $103.7 million.

     On  September  2, 2004,  the  Company  completed  the sale of its  Canadian
natural gas reserves and petroleum  assets.  These Canadian  assets  represented
approximately 221 Bcfe of proved reserves,  producing approximately 61 Mmcfe per
day.  Included in this sale was the Company's 25% interest in  approximately  80
Bcfe of proved  reserves (net of  royalties)  and 32 Mmcfe per day of production
owned by CNGT. In accordance  with SFAS No. 144, the Company's 25% equity method
investment  in CNGT was  considered  part of the larger  disposal  group  (i.e.,
assets to be disposed of together as a group in a single transaction to the same
buyer),  and therefore  evaluated and accounted for as discontinued  operations.
Under  the  terms  of  the   agreement,   Calpine   received  cash  payments  of
approximately  Cdn$808.1  million,  or approximately  US$626.4 million.  Calpine
recorded a pre-tax  gain of  approximately  $104.5  million on the sale of these
Canadian  assets net of $20.1  million in foreign  exchange  losses  recorded in
connection with the settlement of forward contracts entered into to preserve the
US dollar value of the Canadian proceeds.

     In  connection  with  the sale of the oil and gas  assets  in  Canada,  the
Company entered into a seven-year gas purchase agreement  beginning on March 31,
2005, and expiring on October 31, 2011, that allows,  but does not require,  the
Company to  purchase  gas from the buyer at current  market  index  prices.  The
agreement is not asset  specific and can be settled by any  production  that the
buyer has available.

     In connection  with the sale of the Rocky  Mountain gas  reserves,  the New
Mexico San Juan Basin  sales  agreement  allows for the buyer and the Company to
execute  a  ten-year  gas  purchase  agreement  for 100% of the  underlying  gas
production  of sold  reserves,  at market index prices.  Any agreement  would be
subject to mutually agreeable collateral  requirements and other customary terms
and provisions.  As of October 1, 2004, the gas purchase agreement was finalized
and executed between the Company and the buyer.

     The Company  believes  that all final terms of the gas purchase  agreements
described  above are on a market  value and arm's length  basis.  If the Company
elects in the future to exercise a call option over production from the disposed
components, the Company will consider the call obligation to have been met as if
the actual  production  delivered to the Company  under the call was from assets
other than those constituting the disposed components.

     On June 29, 2005,  the Company,  along with its  subsidiaries,  Calpine Gas
Holdings LLC and Calpine Fuels Corporation, announced that it had entered into a
Purchase and Sale  Agreement  with Rosetta,  pursuant to which the Company would
sell  substantially  all of its remaining  domestic oil and gas  exploration and
production  properties  and assets to Rosetta for $1.05  billion,  less  certain
transaction fees and expenses.  The sale closed on July 7, 2005. See Note 15 for
further discussion.

     In  connection  with the sale of the oil and gas  assets  to  Rosetta,  the
Company entered into a two-year gas purchase  agreement expiring on December 31,
2009,  for 100% of the  production of the  Sacramento  basin,  which  represents
approximately  44% of the reserve  assets sold to Rosetta.  The Company will pay
the  prevailing  current  market index price for all amounts  acquired under the
agreement.  The Company believes the gas purchase agreement was negotiated on an
arm's length basis and represents fair value for the production.  Therefore, the
agreement  does not provide  the Company  with  significant  influence  over the
buyer's ability to realize the economic risks and rewards of owning the assets.

     While the transaction closed in July 2005, the Company had met the criteria
necessary to classify the assets and liabilities as held for sale under SFAS 144
as of June  30,  2005.  Consequently,  as of  June  30,  2005,  the  assets  and
liabilities  related  to the  oil and  gas  assets  sold  are  reflected  in the
Consolidated  Condensed  Balance  Sheet as  current  and  long-term  assets  and
liabilities held for sale.

Electric Generation and Marketing

     On January 15, 2004,  the Company  completed  the sale of its 50% undivided
interest in the 545-MW Lost Pines 1 Power  Project to GenTex Power  Corporation,
an affiliate of the LCRA.  Under the terms of the agreement,  Calpine received a
cash  payment  of $148.6  million  and  recorded  a gain  before  taxes of $35.3
million.  In addition,  CES entered into a tolling agreement with LCRA providing
for the option to purchase 250 MW of electricity  through  December 31, 2004. At
December 31, 2003, the Company's  undivided  interest in the Lost Pines facility
was classified as "held for sale" and identified by balance sheet caption in the
Summary section below.

     On May 31, 2005,  the Company  announced that it had agreed to sell Saltend
for  a  total  sale  price  of   approximately   490  million   British   pounds
(approximately  $906 million at the time of the announcement),  plus adjustments
for working capital that were estimated to be  approximately  $19 million at the
time of the  announcement.  The  sale  subsequently  closed  on July  28,  2005,
generating  total  gross  proceeds  of $862.5  million,  $14.5  million of which
related to the estimated  working capital  adjustments.  See Note 15 for further
information related to the closing of the sale. As described further in Note 12,
certain bondholders filed a lawsuit concerning the remaining use of the proceeds
from the sale of Saltend.  While the transaction closed in July 2005, as of June
30, 2005, the Company had met the criteria  necessary to classify the assets and
liabilities related to Saltend as held for sale under SFAS No. 144. These assets
and  liabilities  are  reflected  in the June 30,  2005  Consolidated  Condensed
Balance Sheet as current and long-term  assets and liabilities held for sale and
identified by balance sheet caption in the Summary section below.

Summary

     The Company made  reclassifications  to current and prior period  financial
statements  to reflect the sale or  designation  as "held for sale" of these oil
and gas and  Saltend  assets and  liabilities  and to  separately  classify  the
operating  results of the assets sold and gain on sale of those  assets from the
operating results of continuing operations to discontinued operations.

     The table  below  presents  the  assets  and  liabilities  held for sale by
segment as of June 30, 2005 (in thousands).

     The Company  allocates  interest to  discontinued  operations in accordance
with EITF Issue No. 87-24, "Allocation of Interest to Discontinued  Operations."
The Company includes  interest expense on debt which is required to be repaid as
a result of a disposal  transaction in  discontinued  operations.  Additionally,
other  interest  expense that cannot be  attributed  to other  operations of the
Company is allocated  based on the ratio of net assets to be sold less debt that
is required  to be paid as a result of the  disposal  transaction  to the sum of
total net assets of the Company plus consolidated debt of the Company, excluding
(a) debt of the  discontinued  operation that will be assumed by the buyer,  (b)
debt that is required to be paid as a result of the disposal transaction and (c)
debt that can be directly attributed to other operations of the Company.

     Using the  methodology  above,  the  Company  allocated  specific  interest
expense to its remaining oil and gas properties for  approximately  $139 million
of debt the  Company  was  required  to  repurchase  under the terms of its $785
million  in  principal  amount of First  Priority  Notes.  The  total  amount of
interest  expense  allocated  to the oil and gas  segment  for the three and six
month periods ending June 30, 2005 and 2004 was $5.1 million, $9.9 million, $2.5
million and $4.7  million,  respectively.  The Company also  allocated  specific
interest  expense to the Saltend  entities  for the $620.0  million of preferred
interest  debt that the Company was  required to redeem in  connection  with the
sale of Saltend.  The total amount of interest expense allocated to the electric
generation  segment for the three and six month periods ending June 30, 2005 and
2004  was  $21.3  million,   $38.9  million,  $1.8  million  and  $4.0  million,
respectively.

     Of the  Company's  net  derivative  liabilities,  $238.8  million and $41.4
million are net derivative assets of PCF and CNEM,  respectively,  each of which
is an entity with its existence separate from the Company and other subsidiaries
of the  Company.  The Company  fully  consolidates  CNEM,  and the Company  also
records the net derivative assets of PCF in its balance sheet.

     On March 31, 2005,  Deer Park,  an indirect,  wholly  owned  subsidiary  of
Calpine,  entered into  agreements  to sell power to and buy gas from MLCI.  The
agreements  cover  650 MW of Deer  Park's  capacity,  and  deliveries  under the
agreements  began on April 1, 2005, and continue  through  December 31, 2010. To
assure  performance  under the  agreements,  Deer Park granted MLCI a collateral
interest in the Deer Park Energy Center.  The power and gas  agreements  contain
terms as follows:

Power Agreements

     Under the terms of the power agreements,  Deer Park will sell power to MLCI
at fixed and index  prices with a discount to  prevailing  market  prices at the
time the agreements were executed.  In exchange for the discounted pricing, Deer
Park received an initial cash payment of $195.8 million, net of $17.3 million in
transaction  costs,  and  subsequently  received  additional  cash  payments  of
approximately  $79.3 million as additional power transactions were executed with
discounts to prevailing  market  prices during the second and third  quarters of
2005.  The cash  received  by Deer Park is  sufficiently  small  compared to the
amount  that would be  required  to fully  prepay for the power to be  delivered
under the agreements  that the agreements have been determined to be derivatives
in their entirety  under SFAS No. 133. Of the $79.3 million of additional  power
transactions, additional cash payments of $51.8 million, net of transaction fees
of $1.8 million was received as of June 30,  2005.  The value of the  derivative
liability  at June 30,  2005,  was  $283.8  million.  As Deer Park  makes  power
deliveries   under  the  agreements,   the  liability  will  be  satisfied  and,
accordingly, the derivative liability will be reduced, and Deer Park will record
corresponding  gains in income,  supplementing the revenues  recognized based on
discounted  pricing as deliveries take place. The upfront  payments  received by
Deer Park  from the  transaction  are  recorded  as cash  flows  from  financing
activity in accordance  with guidance  contained in SFAS No. 149,  "Amendment of
Statement 133 on Derivative  Instruments and Hedging Activities" (SFAS No. 149).
SFAS No. 149 requires that companies  present cash flows from  derivatives  that
contain  an  "other-than-insignificant"  financing  element  as cash  flows from
financing  activities.  Under SFAS No.  149, a  contract  that at its  inception
includes  off-market  terms,  or requires an up-front cash  payment,  or both is
deemed to contain an "other-than-insignificant" financing element.

Gas Agreements

     Under the terms of the gas agreements, Deer Park will receive quantities of
gas such that,  when  combined  with fuel supply  provided by Deer Park's  steam
host,  Deer Park will have sufficient  contractual  fuel supply to meet the fuel
needs required to generate the power under the power agreements.  Deer Park will
pay both fixed and variable prices under the gas agreements.  To the extent that
Deer  Park  receives   fixed  prices  for  power,   Deer  Park  will  receive  a
volumetrically  proportionate  quantity  of gas supply at fixed  prices  thereby
fixing the spread  between the revenue Deer Park receives  under the fixed price
power  sales and the cost it pays under the fixed  price gas  purchases.  To the
extent that Deer Park receives  index-based  prices for its power sales, it will
pay  index-based  prices for a  volumetrically  proportionate  amount of its gas
supply.

Relationship of Net Derivative Assets or Liabilities to AOCI

     At any  point in time,  it is highly  unlikely  that  total net  derivative
assets or liabilities  will equal AOCI, 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 or asset account,  thereby creating an imbalance between net
          OCI and net derivative assets and liabilities.

     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,  changes  in the
          derivative  asset or liability are no longer  recorded to OCI. At this
          point,  an AOCI  balance  remains that is not  recognized  in earnings
          until the forecasted initially hedged 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.

its accumulated other comprehensive loss, net of tax from derivative instruments
at June 30, 2005 (in thousands):

     Presentation  of Revenue  Under EITF Issue No.  03-11  "Reporting  Realized
Gains and Losses on Derivative  Instruments That Are Subject to SFAS No. 133 and
Not `Held for  Trading  Purposes'  As Defined in EITF  Issue No.  02-3:  "Issues
Involved in Accounting  for Derivative  Contracts Held for Trading  Purposes and
Contracts  Involved in Energy  Trading and Risk  Management  Activities"  -- The
Company  accounts  for certain of its power sales and  purchases  on a net basis
under EITF Issue No. 03-11,  which the Company adopted on a prospective basis on
October 1, 2003.  Transactions with either of the following  characteristics are
presented net in the Company's Consolidated Condensed Financial Statements:  (1)
transactions  executed in a back-to-back buy and sale pair, primarily because of
market protocols;  and (2) physical power purchase and sale  transactions  where
the  Company's  power  schedulers  net the physical  flow of the power  purchase
against the physical  flow of the power sale (or "book out" the  physical  power
flows) as a matter of scheduling  convenience  to eliminate the need to schedule
actual  power  delivery.  These  book out  transactions  may occur with the same
counterparty or between different counterparties where the Company has equal but
offsetting physical purchase and delivery  commitments.  In accordance with EITF
Issue No. 03-11,  the Company  netted the purchases of $272.6 million and $322.0
million  against sales in the quarters  ended June 30, 2005,  and June 30, 2004,
respectively.  The Company  netted the  purchases  of $576.3  million and $692.5
million  against sales in the six months ended June 30, 2005, and June 30, 2004,
respectively.

     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 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 as of
June 30, 2005.

     As of June 30, 2005,  the maximum length of time over which the Company was
hedging its  exposure  to the  variability  in future cash flows for  forecasted
transactions  was 7 and 12 years,  for commodity  and interest  rate  derivative
instruments,  respectively.  The Company estimates that pre-tax losses of $268.8
million,  of  which  $168.8  relates  to  discontinued   operations,   would  be
reclassified  from OCI into  earnings  during the twelve  months  ended June 30,
2006, 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.

     The table below presents the pre-tax gains  (losses)  currently held in OCI
that will be recognized annually into earnings,  assuming constant gas and power
prices, interest rates, and exchange rates over time (in thousands):

10.  Comprehensive Income (Loss)

     Comprehensive income (loss) is the total of net income (loss) and all other
non-owner  changes in equity.  Comprehensive  income  includes the Company's net
income,  unrealized gains and losses from derivative instruments that qualify as
cash flow hedges, unrealized gains and losses from available-for-sale securities
which are marked to market,  the Company's share of its equity method investee's
OCI, and the effects of foreign currency  translation  adjustments.  The Company
reports  AOCI in its  Consolidated  Balance  Sheet.  The tables below detail the
changes during the six months ended June 30, 2005 and 2004 in the Company's AOCI
balance and the components of the Company's comprehensive income (in thousands):

11.  Loss Per Share

     Basic  loss per  common  share was  computed  by  dividing  net loss by the
weighted average number of common shares outstanding for the respective periods.
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 distribution  expense avoided upon conversion.  The reconciliation
of basic and diluted loss per common share is shown in the  following  table (in
thousands, except per share data).

     The Company incurred losses before discontinued operations for the quarters
ended  June 30,  2005 and  2004.  As a  result,  basic  shares  were used in the
calculations  of fully  diluted  loss per  share for  these  periods,  under the
guidelines of SFAS No. 128 as using the basic shares  produced the more dilutive
effect on the loss per share.  Potentially convertible securities,  shares to be
purchased  under the Company's  ESPP and  unexercised  employee stock options to
purchase  a weighted  average of 10.8  million  and 60.6  million  shares of the
Company's  common stock were not included in the  computation  of diluted shares
outstanding  during the six months  ended June 30, 2005 and 2004,  respectively,
because such inclusion would be antidilutive.

     For the  three  months  ended  June 30,  2005 and 2004,  approximately  0.1
million and 4.0 million,  respectively,  weighted common shares of the Company's
outstanding  2006  Convertible  Senior Notes were  excluded from the diluted EPS
calculations as the inclusion of such shares would have been antidilutive.

     In connection  with the convertible  debentures  payable to Calpine Capital
Trust III, net of  repurchases,  for the quarters  ended June 30, 2005 and 2004,
there  were  9.3  million  and  11.9  million  weighted  average  common  shares
potentially  issuable,  respectively,  that were  excluded  from the diluted EPS
calculation as their inclusion would be antidilutive. The convertible debentures
were redeemed in full on July 13, 2005.

     For the  quarters  ended June 30, 2005 and 2004,  under the new guidance of
EITF  04-08  there  were no shares  potentially  issuable  and thus  potentially
included in the diluted EPS  calculation  under the Company's  2023  Convertible
Notes,  2014  Convertible  Notes and 2015  Convertible  Notes issued in November
2003, September 2004 and June 2005, respectively,  because the Company's closing
stock  price at each  period end was below the  conversion  price.  However,  in
future  reporting  periods where the Company's  closing stock price is above the
conversion  price for any of these  convertible  instruments and the Company has
income  before  discontinued  operations  and  cumulative  effect of a change in
accounting principle, the maximum potential shares issuable under the conversion
provisions  of the notes  would be as  presented  below.  The  actual  number of
potential shares will depend on the closing stock price at conversion.

     o    2023  Convertible  Notes -- If the  Company's  closing  stock price is
          above  the  instrument's  conversion  price of  $6.50,  a  maximum  of
          approximately  97.5 million  shares would be included (if dilutive) in
          the diluted EPS calculation;

     o    2014  Convertible  Notes -- If the  Company's  closing  stock price is
          above  the  instrument's  conversion  price of  $3.85,  a  maximum  of
          approximately  166.7 million shares would be included (if dilutive) in
          the diluted EPS calculation;

     o    2015  Convertible  Notes -- If the  Company's  closing  stock price is
          above  the  instrument's  conversion  price of  $4.00,  a  maximum  of
          approximately  163.0 million shares would be included (if dilutive) in
          the diluted EPS calculation;

     For the quarter ended June 30, 2005,  1.2 million  weighted  average common
shares of the Company's  contingently  issuable (unvested)  restricted stock was
excluded from the calculation of diluted EPS because the Company's closing stock
price has not reached  the price at which the shares  vest,  and,  as  discussed
above, inclusion would have been anti-dilutive.

     In conjunction with the offering of the 2014 Convertible Notes, the Company
entered into a ten-year Share Lending Agreement with DB London,  under which the
Company  loaned DB London 89 million shares of newly issued Calpine common stock
in  exchange  for a loan fee of $.001 per share  and  other  consideration.  The
Company has excluded the 89 million  shares of common stock subject to the Share
Lending Agreement from the EPS calculation.

     See Note 2 for a discussion  of the  potential  impact of SFAS No. 128-R on
the calculation of diluted EPS.

Litigation

     The  Company  is party to various  litigation  matters  arising  out of the
normal course of business,  the more significant of which are summarized  below.
The ultimate  outcome of each of these matters  cannot  presently be determined,
nor can the liability that could  potentially  result from a negative outcome be
reasonably  estimated  presently  for every case.  The liability the Company may
ultimately  incur  with  respect  to any one of these  matters in the event of a
negative outcome may be in excess of amounts  currently  accrued with respect to
such matters and, as a result of these matters,  may  potentially be material to
the Company's Consolidated Financial Statements.

     Securities  Class Action  Lawsuits.  Beginning  on March 11, 2002,  fifteen
securities class action complaints were filed in the U.S. District Court for the
Northern  District of California  against  Calpine and certain of its employees,
officers, and directors.  All of these actions were ultimately assigned to Judge
Saundra Brown Armstrong,  and Judge Armstrong  ordered the actions  consolidated
for  all  purposes  on  August  16,  2002,  as In re  Calpine  Corp.  Securities
Litigation,  Master File No. C 02-1200 SBA.  There is  currently  only one claim
remaining from the consolidated  actions: a claim for violation of Section 11 of
the  Securities  Act. The Court has  dismissed  all of the claims  brought under
Section 10(b) of the Securities Exchange Act of 1934 with prejudice.

     On October 17,  2003,  the  then-lead  plaintiffs  filed the third  amended
complaint ("TAC"),  which alleges violations of Section 11 of the Securities Act
by Calpine,  Peter  Cartwright,  Ann B. Curtis and Charles B. Clark, Jr. The TAC
alleges that the  registration  statement and  prospectuses  for Calpine's  2011
Notes contained materially false or misleading statements about the factors that
caused the power shortages in California in 2000-2001 and the resulting increase
in wholesale energy prices.  The lead plaintiff in this action contends that the
true but undisclosed  cause of the energy crisis is that Calpine and other power
producers  were engaging in physical and economic  withholding  of  electricity.
Lead  plaintiff  moved  for  certification  of a  class  consisting  of all  who
purchased Notes between February 8, 2001 and January 27, 2003. On June 10, 2005,
the Court held a hearing on the motion for class  certification,  and denied the
motion without prejudice.  Lead plaintiff asked for, and received, leave to file
a brief on June  24,  2005 to  attempt  to  demonstrate  why a class  should  be
certified,  and what its parameters should be. Defendant responded to that brief
on July 8, 2005. The parties are awaiting Judge Armstrong's ruling.

     The Court has set a November 7, 2005, trial date. Fact discovery was closed
on August 1, 2005.  We consider  the  lawsuit to be without  merit and intend to
continue to defend vigorously against the allegations.

     Hawaii Structural  Ironworkers Pension Fund v. Calpine, et al. This case is
a Section 11 case brought as a class action on behalf of purchasers in Calpine's
April  2002 stock  offering.  This case was filed in San Diego  County  Superior
Court on March 11,  2003,  but  defendants  won a motion to transfer the case to
Santa Clara County.  Defendants in this case are Calpine, Peter Cartwright,  Ann
B. Curtis,  John Wilson,  Kenneth Derr,  George  Stathakis,  Credit Suisse First
Boston, Banc of America Securities, Deutsche Bank Securities, and Goldman, Sachs
& Co. Plaintiff is the Hawaii Fund.

     The Hawaii Fund alleges that the prospectus and registration  statement for
the April 2002 offering had false or misleading statements regarding:  Calpine's
actual  financial  results  for 2000 and  2001;  Calpine's  projected  financial
results for 2002;  Mr.  Cartwright's  agreement  not to sell or purchase  shares
within 90 days of the  offering;  and  Calpine's  alleged  involvement  in "wash
trades." A central  allegation of the complaint is that a March 2003 restatement
concerning  the accounting for two  sales-leaseback  transactions  revealed that
Calpine had misrepresented its financial results in the  prospectus/registration
statement for the April 2002 offering.

     There is no trial date in this action.  The next  scheduled  court  hearing
will be a case  management  conference  on January 10,  2006,  at which time the
court may set a trial date.  We consider  this  lawsuit to be without  merit and
intend to continue to defend vigorously against the allegations.

     Phelps v. Calpine Corporation, et al. On April 17, 2003, James Phelps filed
a class action complaint in the Northern District of California, alleging claims
under the ERISA. On May 19, 2003, a nearly  identical class action complaint was
filed in the Northern  District by Lenette  Poor-Herena.  The parties  agreed to
have both of the ERISA  actions  assigned to Judge  Armstrong,  who oversees the
above-described federal securities class action and the Gordon derivative action
(see below).  On August 20, 2003,  pursuant to an agreement between the parties,
Judge  Armstrong  ordered that the two ERISA actions be  consolidated  under the
caption,  In re Calpine Corp.  ERISA Litig.,  Master File No. C 03-1685 SBA (the
"ERISA  Class  Action").  Plaintiff  James  Phelps  filed a  consolidated  ERISA
complaint on January 20, 2004 ("Consolidated Complaint"). Ms. Poor-Herena is not
identified as a plaintiff in the Consolidated Complaint.

     The  Consolidated  Complaint  defines the class as all participants in, and
beneficiaries  of, the Plan for whose accounts  investments were made in Calpine
stock during the period from January 5, 2001 to the  present.  The  Consolidated
Complaint  names as defendants  Calpine,  the members of its Board of Directors,
the Plan's Advisory  Committee and its members (Kati Miller,  Lisa Bodensteiner,
Rick Barraza, Tom Glymph,  Patrick Price, Trevor Thor, Bob McCaffrey,  and Bryan
Bertacchi),  signatories of the Plan's Annual  Return/Report of Employee Benefit
Plan Forms 5500 for 2001 and 2002 (Pamela J. Norley and Marybeth Kramer-Johnson,
respectively),  an  employee  of a  consulting  firm  hired by the  Plan  (Scott
Farris), and unidentified fiduciary defendants.

     The Consolidated Complaint alleges that defendants breached their fiduciary
duties involving the Plan, in violation of ERISA, by  misrepresenting  Calpine's
actual financial results and earnings  projections,  failing to disclose certain
transactions  between  Calpine  and  Enron  that  allegedly  inflated  Calpine's
revenues,  failing to disclose that the shortage of power in  California  during
2000-2001 was due to withholding of capacity by certain power companies, failing
to investigate  whether  Calpine common stock was an appropriate  investment for
the Plan, and failing to take appropriate actions to prevent losses to the Plan.
In addition,  the Consolidated  Complaint alleges that certain of the individual
defendants  suffered  from  conflicts  of interest due to their sales of Calpine
stock during the class period.

     Defendants  moved to dismiss the  Consolidated  Complaint.  Judge Armstrong
granted the motion and dismissed  three of the four claims with  prejudice.  The
remaining  claim,  for  misrepresentation,  was  dismissed  with leave to amend.
Plaintiff  filed  a  Consolidated   Amended  Complaint  on  June  3,  2005.  The
Consolidated  Amended Complaint names as defendants Calpine  Corporation and the
members of the Advisory Committee for the Plan. Defendants have filed motions to
dismiss the Consolidated  Amended Complaint,  which are currently  scheduled for
hearing on September  13, 2005. We consider this lawsuit to be without merit and
intend to continue to defend vigorously against the allegations.

     Johnson v. Peter  Cartwright,  et al. On December 17,  2001, a  shareholder
filed a derivative lawsuit on behalf of Calpine against its directors and one of
its senior officers. This lawsuit is styled Johnson vs. Cartwright,  et al. (No.
CV803872)  and is pending in  California  Superior  Court in Santa Clara County,
California. 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.  In December 2002,
the court  dismissed  the  complaint  with  respect to  certain of the  director
defendants for lack of personal  jurisdiction,  though plaintiff may appeal this
ruling.  In early February 2003,  plaintiff filed an amended  complaint,  naming
additional  officer  defendants.  Calpine and the  individual  defendants  filed
demurrers  (motions to dismiss) and a motion to stay the case in March 2003.  On
July 1, 2003, the Court granted  Calpine's  motion to stay this proceeding until
the  above-described  federal  Section 11 action is resolved,  or until  further
order of the Court.  The Court did not rule on the  demurrers.  We consider this
lawsuit  to be  without  merit  and  intend  to defend  vigorously  against  the
allegations if the stay is ever lifted.

     Gordon v. Peter Cartwright, et al. On August 8, 2002, a shareholder filed a
derivative suit in the United States District Court for the Northern District of
California  on behalf of Calpine  against  its  directors,  captioned  Gordon v.
Cartwright, et al. similar to Johnson v. Cartwright.  Motions have been filed to
dismiss the action against certain of the director  defendants on the grounds of
lack of personal  jurisdiction,  as well as to dismiss the complaint in total on
other grounds.  In February  2003,  plaintiff  agreed to stay these  proceedings
until the above-described  federal Section 11 action is resolved, and to dismiss
without  prejudice  certain director  defendants.  The Court did not rule on the
motions to dismiss the  complaint  on  non-jurisdictional  grounds.  On March 4,
2003,  plaintiff  filed  papers with the court  voluntarily  agreeing to dismiss
without prejudice his claims against three of the outside directors. We consider
this  lawsuit to be without  merit and intend to defend  vigorously  against the
allegations if the stay is ever lifted.

     International Paper Company v. Androscoggin Energy LLC. In October 2000, IP
filed a complaint against AELLC alleging that AELLC breached certain contractual
representations  and  warranties  arising  out of an  Amended  ESA by failing to
disclose facts  surrounding  the  termination,  effective May 8, 1998, of one of
AELLC's fixed-cost gas supply  agreements.  The steam price paid by IP under the
ESA is derived from AELLC's cost of gas under its gas supply agreements.  We had
acquired a 32.3% economic  interest and a 49.5% voting interest in AELLC as part
of the  SkyGen  transaction,  which  closed  in  October  2000.  AELLC  filed  a
counterclaim  against IP that has been  referred to  arbitration  that AELLC may
commence at its  discretion  upon further  evaluation.  On November 7, 2002, the
court  issued an opinion on the  parties'  cross  motions for  summary  judgment
finding in AELLC's favor on certain matters though granting  summary judgment to
IP on the liability  aspect of a particular  claim against AELLC. The court also
denied a motion submitted by IP for preliminary  injunction to permit IP to make
payment of funds into escrow (not directly to AELLC) and require AELLC to post a
significant bond.

     In  mid-April  of 2003,  IP  unilaterally  availed  itself to  self-help in
withholding  amounts in excess of $2 million as a setoff for litigation expenses
and fees  incurred  to date as well as an  estimated  portion  of a rate fund to
AELLC.  AELLC has  submitted  an amended  complaint  and request  for  immediate
injunctive relief against such actions.  The court heard the motion on April 24,
2003 and  ordered  that IP must pay the  approximate  $1.2  million  withheld as
attorneys' fees related to the litigation as any such perceived  entitlement was
premature,  but declined to order  injunctive  relief on the  incomplete  record
concerning the offset of $799,000 as an estimated pass-through of the rate fund.
IP complied  with the order on April 29, 2003 and  tendered  payment to AELLC of
the  approximate  $1.2  million.  On June 26, 2003,  the court  entered an order
dismissing AELLC's amended counterclaim without prejudice to AELLC re-filing the
claims as breach of contract claims in a separate lawsuit. On December 11, 2003,
the court denied in part IP's summary judgment motion pertaining to damages.  In
short,  the court:  (i)  determined  that, as a matter of law, IP is entitled to
pursue an action for damages as a result of AELLC's breach,  and (ii) ruled that
sufficient  questions of fact remain to deny IP summary  judgment on the measure
of damages as IP did not sufficiently establish causation resulting from AELLC's
breach of contract (the liability aspect of which IP obtained a summary judgment
in December 2002). On February 2, 2004, the parties filed a Final Pretrial Order
with the court. The case recently proceeded to trial, and on November 3, 2004, a
jury verdict in the amount of $41 million was rendered in favor of IP. AELLC was
held liable on the  misrepresentation  claim,  but not on the breach of contract
claim.  The verdict amount was based on  calculations  proffered by IP's damages
experts.  AELLC has made an additional accrual to recognize the jury verdict and
the Company has recognized its 32.3% share.

     AELLC filed a post-trial  motion  challenging both the determination of its
liability and the damages award and, on November 16, 2004,  the court entered an
order staying the execution of the judgment.  The order staying execution of the
judgment  has not  expired.  If the  judgment  is not vacated as a result of the
post-trial motions, AELLC intends to appeal the judgment.

     Additionally,  on November 26, 2004,  AELLC filed a voluntary  petition for
relief under Chapter 11 of the Bankruptcy  Code. As noted above, we had acquired
a 32.3%  economic  interest and a 49.5% voting  interest in AELLC as part of the
SkyGen  transaction,  which  closed in  October  2000.  AELLC is  continuing  in
possession  of its property and is operating and  maintaining  its business as a
debtor in  possession,  pursuant to Sections  1107(a) and 1108 of the Bankruptcy
Code. No request has been made for the  appointment  of a trustee or examiner in
the proceeding,  and no official  committee of unsecured  creditors has yet been
appointed by the Office of the United States  Trustee.  On January 21, 2005, the
U.S. Bankruptcy Court, District of Maine, modified the automatic stay imposed by
11 USC Section 362(a) upon motion by AELLC to allow the  post-trials  motions to
be  adjudicated  and  appeals  made to the  Seventh  Circuit  Court  of  Appeals
accordingly.

     Panda Energy International,  Inc., et al. v. Calpine Corporation, et al. On
November 5, 2003, Panda filed suit against Calpine and certain of its affiliates
in the  United  States  District  Court  for the  Northern  District  of  Texas,
alleging,  among  other  things,  that the Company  breached  duties of care and
loyalty  allegedly  owed to Panda by failing to correctly  construct and operate
the Oneta power plant, which the Company acquired from Panda, in accordance with
Panda's  original  plans.  Panda alleges that it is entitled to a portion of the
profits  from Oneta and that  Calpine's  actions  have  reduced the profits from
Oneta  thereby  undermining  Panda's  ability to repay monies owed to Calpine on
December 1, 2003, under a promissory note on which  approximately  $38.6 million
(including interest through December 1, 2003) is currently outstanding.  Calpine
filed a  counterclaim  against Panda based on a guaranty and a motion to dismiss
as  to  the  causes  of  action  alleging  federal  and  state  securities  laws
violations.  The court recently granted Calpine's motion to dismiss, but allowed
Panda an opportunity to replead.  The Company  considers  Panda's  lawsuit to be
without  merit and intends to  vigorously  defend it.  Discovery is currently in
progress.  The Company stopped  accruing  interest income on the promissory note
due December 1, 2003, as of the due date because of Panda's default in repayment
of the note. Trial is currently set for February 27, 2006.

     California  Business & Professions  Code Section 17200 Cases,  of which the
lead case is T&E Pastorino Nursery v. Duke Energy Trading and Marketing, L.L.C.,
et al. This purported class action complaint filed in May 2002 against 20 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 eight other
similar  complaints for violations of Section 17200.  The Company  considers the
allegations  to be  without  merit,  and filed a motion to dismiss on August 28,
2003. The court granted the motion, and plaintiffs  appealed.  The Ninth Circuit
has issued a decision  affirming the dismissal of the Pastorino  group of cases.
The  Plaintiffs  did not  attempt  to appeal the Ninth  Circuit's  ruling to the
Supreme Court so the matter is resolved.

     Prior to the motion to dismiss being granted, one of the actions, captioned
Millar v.  Allegheny  Energy  Supply  Co.,  LLP, et al.,  was  remanded to state
superior court of Alameda County, California. On January 12, 2004, CES was added
as a defendant in Millar.  This action includes similar allegations to the other
Section 17200 cases,  but also seeks rescission of the long-term power contracts
with the CDWR.  Millar was removed to federal  court,  but has now been remanded
back to State Superior Court for handling.  Hearings on multiple demurrers is to
be held on  September  7, 2005.  The Company  considers  the  allegations  to be
without merit, and has filed a demurrer.

     Nevada Power Company and Sierra  Pacific  Power  Company v. Calpine  Energy
Services,  L.P. before the FERC,  filed on December 4, 2001,  Nevada Section 206
Complaint.  On December 4, 2001,  NPC and SPPC filed a complaint with 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,
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 spot
power market was dysfunctional  and that they are unjust and  unreasonable.  The
complaint   therefore   sought   modification  of  the  contract   prices.   The
administrative  law judge issued an Initial  Decision on December 19, 2002, that
found for Calpine and the other  respondents in the case and denied NPC and SPPC
the relief that they were seeking.  In a June 26, 2003 order,  FERC affirmed the
judge's findings and dismissed the complaint,  and subsequently denied rehearing
of that order. The matter is pending on appeal before the United States Court of
Appeals for the Ninth  Circuit.  The Company has  participated  in briefing  and
arguments before the Ninth Circuit defending the FERC orders, but the Company is
not able to predict at this time the outcome of the Ninth Circuit appeal.

     Transmission  Service  Agreement  with Nevada Power  Company.  On March 16,
2004,  NPC  filed  a  petition  for  declaratory   order  at  FERC  (Docket  No.
EL04-90-000) asking that an order be issued requiring Calpine and Reliant Energy
Services,  Inc. to pay for transmission service under their Transmission Service
Agreements  ("TSAs") with NPC or, if the TSAs are terminated,  to pay the lesser
of the  transmission  charges  or a pro rata  share of the  total  cost of NPC's
Centennial  Project  (approximately  $33  million  for  Calpine).   Calpine  had
previously provided security to NPC for these costs in the form of a surety bond
issued  by  FFIC.  The  Centennial  Project  involves  construction  of  various
transmission facilities in two phases; Calpine's Moapa Energy Center ("MEC") was
scheduled to receive service under its TSA from facilities yet to be constructed
in the second phase of the  Centennial  Project.  Calpine filed a protest to the
petition  asserting that Calpine will take service under the TSA if NPC proceeds
to execute a purchase power agreement  ("PPA") with MEC based on its winning bid
in the Request for Proposals that NPC conducted in 2003.

     On November 18, 2004, the FERC issued a decision in Docket No. EL04-90-000,
which was initiated by NPC's filing of a petition for declaratory  order at FERC
on March 16, 2004 asking that an order be issued  requiring  Calpine and Reliant
Energy Services,  Inc.  ("Reliant") to pay for transmission  service under their
Transmission Service Agreements  (collectively,  the "TSAs") with NPC or, if the
TSAs, are  terminated,  to pay the lesser of the  transmission  charges or a pro
rata  share of the total cost of NPC's  Centennial  Project  (approximately  $33
million for Calpine).  The November 18, 2004 decision found that neither Calpine
nor Reliant had the right to unilaterally  terminate their  respective TSAs, and
that upon commencement of service both Calpine and Reliant would be obligated to
pay either the associated  demand charges for service or their  respective share
of the capital cost  associated  with the  transmission  upgrades that have been
made in order to provide such service. The November 18, 2004 order, however, did
not  indicate  the amount or measure of damages that would be owed to NPC in the
event that either Calpine or Reliant breached its respective  obligations  under
the TSAs.

     On December 10, 2004,  NPC filed a Request for Rehearing  alleging that the
FERC had erred in holding that a  determination  of damages for breach of either
Calpine or Reliant was premature. In its December 10th Request for Rehearing NPC
argued that both Calpine and Reliant had breached their respective TSAs. Calpine
filed an Answer on January 4, 2005  requesting  that the FERC deny NPC's Request
for  Rehearing on the basis that the Request for Rehearing  misconstrues  FERC's
November  18th Order and that the  question of damages  under the Calpine TSA is
before U.S.  District Court in Nevada.  On April 20, 2005, FERC issued its Order
Denying Request for Rehearing. In the Order, the Commission denies NPC's request
for rehearing,  finding that the dispute between Calpine and NPC is "effectively
a  contractual  interpretation  dispute"  and does not warrant  assertion of the
Commission's primary jurisdiction and is best left to a court.

     In light of the  November  18, 2004 order,  on  November  22, 2004  Calpine
delivered  to NPC a notice  (the  "November  22, 2004  Letter")  that it did not
intend to perform  its  obligations  under the  Calpine  TSA and that NPC should
exercise  its duty to mitigate  its  damages,  if any,  and should not incur any
additional costs or expenses in reliance upon the TSA or for Calpine's  account.
In addition,  Calpine  introduced the November 22, 2004 Letter before the Public
Utilities  Commission of Nevada ("PUCN") in the proceeding regarding NPC's third
amendment to its  integrated  resource  plan wherein NPC is seeking  approval to
proceed with the construction of the Harry Allen to Mead  transmission line (the
"HAM Line"),  which is the  transmission  project that is intended to serve both
Calpine and  Reliant's  TSAs.  On December  28,  2004,  the PUCN issued an order
granting  NPC's  request to proceed with the  construction  of the HAM Line.  On
January 11, 2005, Calpine filed a Petition for  Reconsideration  before the PUCN
regarding  December 28, 2004,  order.  On February 9, 2005,  the PUCN issued the
Order Denying Petitions For  Reconsideration.  At this time Calpine is unable to
predict the impact of the  December 28,  2004,  and the  February 9, 2005,  PUCN
orders,  if any on the District  Court  Complaint or any possible  action by NPC
before  the  FERC  regarding  Calpine's  notice  that it will  not  perform  its
obligations under the Calpine TSA.

     The bond issued by FFIC, by its terms,  expired on May 1, 2004. On or about
April 27, 2004,  NPC asserted to FFIC that Calpine had committed a default under
the bond by failing to agree to renew or  replace  the bond upon its  expiration
and made demand on FFIC for the full amount of the surety bond, $33,333,333.  On
April 29, 2004, FFIC filed a complaint for declaratory  relief in state superior
court of Marin County,  California in connection  with this demand.  NPC filed a
motion to quash  service for lack of personal  jurisdiction  in  California.  On
September  3,  2004,  the  superior  court  granted  NPC's  motion,  and NPC was
dismissed  from  the  proceeding.  Subsequently,  FFIC  agreed  to  dismiss  the
complaint as to Calpine.  On  September  30, 2004 NPC filed a complaint in state
district  court of Clark County,  Nevada against  Calpine,  Moapa Energy Center,
LLC, FFIC and unnamed parties alleging, among other things, breach by Calpine of
its obligations  under the TSA and breach by FFIC of its  obligations  under the
surety bond. In November 2004,  this  proceeding was removed from state court to
United States  District  Court for the District of Nevada.  On December 10, FFIC
filed a Motion to Dismiss,  which was granted on May 25,  2005.  NPC has filed a
Motion to Amend the  Complaint  and a Motion  for  Reconsideration  of the above
dismissal.  At this  time,  Calpine  is unable to  predict  the  outcome of this
proceeding.

     Calpine Canada Natural Gas Partnership v. Enron Canada Corp. On February 6,
2002,  Calpine  Canada filed a complaint in the Alberta  Court of Queens  Branch
alleging that Enron Canada owed it approximately US$1.5 million from the sale of
gas in  connection  with two Master Firm gas  Purchase and Sale  Agreements.  To
date, Enron Canada has not sought  bankruptcy  relief and has  counterclaimed in
the amount of US$18  million.  We have  finished  discovery and are currently in
settlement discussions. The Company believes that Enron Canada's counterclaim is
without merit and intends to vigorously defend against it.

     Estate of Jones,  et al. v.  Calpine  Corporation.  On June 11,  2003,  the
Estate of  Darrell  Jones and the  Estate of  Cynthia  Jones  filed a  complaint
against Calpine in the United States District Court for the Western  District of
Washington. Calpine purchased Goldendale Energy, Inc., a Washington corporation,
from Mr.  Darrell Jones of NESCO.  The agreement  provided,  among other things,
that upon "Substantial Completion" of the Goldendale facility, Calpine would pay
Mr. Jones (i) $6.0 million and (ii) $18.0  million less $0.2 million per day for
each  day  that  elapsed  between  July 1,  2002,  and the  date of  substantial
completion.  Substantial  completion  of the  Goldendale  facility  occurred  in
September  2004 and the daily  reduction  in the payment  amount has reduced the
$18.0  million  payment to zero.  The  complaint  alleged that by not  achieving
substantial  completion by July 1, 2002,  Calpine breached its contract with Mr.
Jones, violated a duty of good faith and fair dealing, and caused an inequitable
forfeiture.  On July 28, 2003,  Calpine  filed a motion to dismiss the complaint
for failure to state a claim upon which relief can be granted. The court granted
Calpine's motion to dismiss the complaint on March 10, 2004.  Plaintiffs filed a
motion for reconsideration of the decision, which was denied.  Subsequently,  on
June 7, 2004,  plaintiffs  filed a notice of appeal.  Calpine  filed a motion to
recover  attorneys'  fees from NESCO,  which was  recently  granted at a reduced
amount.  Calpine  held back  $100,000  of the $6 million  payment to the estates
(which  has been  remitted)  to ensure  payment  of these  fees.  The  matter is
currently  on appeal,  and both  parties  have filed  briefs with the  appellate
court.

     Calpine  Energy  Services v. Acadia Power  Partners.  Calpine,  through its
subsidiaries,  owns 50% of Acadia PP which company owns the Acadia Energy Center
near  Eunice,  Louisiana  (the  "Facility").  A Cleco Corp  subsidiary  owns the
remaining 50% of Acadia PP. CES is the purchaser  under two PPAs with Acadia PP,
which agreements  entitle CES to all of the Facility's  capacity and energy.  In
August  2003  certain  transmission  constraints  previously  unknown to CES and
Acadia PP began to severely limit the ability of CES to obtain all of the energy
from the Facility.  CES has asserted that it is entitled to certain relief under
the purchase agreements,  to which assertions Acadia PP disagrees.  Accordingly,
the parties are engaged in the alternative dispute resolution steps set forth in
the  PPAs.  Recently,  the  parties  extended  a statue of  limitations  tolling
agreement to extend the time for binding  arbitration (up to and including until
August 12,  2005) in order for  negotiations  to  continue.  CES,  however,  can
initiate  arbitration  if settlement  is not  progressing  appropriately.  It is
expected that the parties will be able to resolve these disputes.

     Hulsey,  et al. v. Calpine  Corporation.  On September 20, 2004,  Virgil D.
Hulsey,  Jr. (a current  employee)  and Ray Wesley (a former  employee)  filed a
class action wage and hour lawsuit  against  Calpine  Corporation and certain of
its  affiliates.  The complaint  alleges that the  purported  class members were
entitled to overtime pay and Calpine  failed to pay the purported  class members
at legally required overtime rates. The matter has been transferred to the Santa
Clara  County  Superior  Court and  Calpine  filed an answer on January 7, 2005,
denying  plaintiffs'  claims.  The parties are  currently  engaged in settlement
discussions as an alternative to litigation.

     Michael  Portis v. Calpine  Corp.  -- Complaint  Filed with  Department  of
Labor.  On January 25, 2005,  Michael Portis  ("Portis"),  a former  employee of
Calpine,  brought a  complaint  to the United  States  Department  of Labor (the
"DOL"), alleging that his employment with the Company was wrongfully terminated.
Portis  alleges  that Calpine and its  subsidiaries  evaded sales and use tax in
various  states and in doing so filed false tax reports and that his  employment
was  terminated  in  retaliation  for  having  reported  these   allegations  to
management.   Portis  claims  that  the  Company's  alleged  actions  constitute
violations of the employee  protection  provisions of the Sarbanes  Oxley Act of
2002. On April 27, 2005, the DOL determined that Portis'  retaliatory  discharge
complaint  had no merit and  dismissed  it. Portis filed his notice of appeal on
June 12, 2005.  Administrative  Law Judge  Richard  Huddleston  was assigned the
appeal. On July 11, 2005, a scheduling conference was held with Judge Huddleston
and the hearing of the appeal was set for October 12 and 13,  2005.  The parties
are currently engaged in discovery and negotiating an immediate date for Portis'
deposition.  The Company  considers  Portis'  complaint to be without  merit and
intends to continue to vigorously defend against the complaint.

     Auburndale Power Partners and Cutrale. Calpine Corporation owns an interest
in the Auburndale PP cogeneration  facility,  which provides steam to Cutrale, a
juice  company.  The  Auburndale PP facility  currently  operates on a "cycling"
basis  whereby the plant  operates  only a portion of the day.  During the hours
that the Auburndale PP facility is not operating, Auburndale PP does not provide
steam to Cutrale.  Cutrale has filed an arbitration claim alleging that they are
entitled to damages due to Auburndale PP's failure to provide them with steam 24
hours a day.  Auburndale  PP  disagreed  with  Cutrale's  position  based on its
interpretation  of the  contractual  language  in the  Steam  Supply  Agreement.
Binding arbitration was conducted on the contractual  interpretation  issue only
(reserving the  remedy/damage  issue for a second phase to the  arbitration) and
the  arbitrator  found in favor of  Cutrale's  contractual  interpretation.  The
proceeding now turns to the second phase,  the resolution of the issue regarding
the   appropriate   remedy/damage   determination.   To  preserve  our  positive
relationship with Cutrale,  Auburndale PP continues to try to resolve the matter
through a commercial settlement.

     Harbert  Distressed  Investment  Master Fund, Ltd. v. Calpine Canada Energy
Finance II ULC,  et al. On May 5, 2005,  Harbert  Distressed  Investment  Master
Fund, Ltd. (the "Harbert Fund") filed an Originating  Notice  (Application) (the
"Application")  in the Supreme Court of Nova Scotia against Calpine  Corporation
and certain of its subsidiaries,  including Calpine Canada Energy Finance II ULC
("Finance  II"),  the issuer of certain  bonds (the "Bonds") held by the Harbert
Fund and Calpine Canada  Resources  Company  (formerly  Calpine Canada Resources
Ltd.) ("CCR"),  the parent company of Finance II and the indirect parent company
of Calpine's  Saltend.  The Bonds have been  guaranteed by Calpine.  The Harbert
Fund  alleged  that  Calpine,  CCRC and Finance II violated  the Harbert  Fund's
rights under Nova Scotia laws in connection with certain financing  transactions
completed by CCRC or subsidiaries of CCRC. Wilmington Trust Company, the trustee
under the  indenture  governing the Bonds (the  "Trustee"),  applied to become a
co-applicant  in the suit on behalf of all  holders of Bonds.  The  hearing  was
conducted on July 6, 7 and 8, 2005 before the Nova Scotia Supreme Court.  By way
of  Consent  Order  dated  July 20,  2005,  the  Harbert  Fund  and the  Trustee
discontinued  the claim as against Calpine European Funding (Jersey) Limited and
Calpine (Jersey) Limited, which had originally been named as respondents.

     At the end of the hearing,  the Harbert Fund and the Trustee confirmed that
they were not seeking to block the sale of Saltend,  and that sale was completed
on July 28, 2005.  The Harbert Fund and the Trustee sought relief at the hearing
requiring that the proceeds of the sale of Saltend,  after  repayment to certain
preferred  shareholders  and payment of certain  interest and transaction  costs
(the "Net  Proceeds"),  remain at CCRC or under the control of CCRC. The Harbert
Fund and Trustee  further  sought an order that an additional sum be required to
be placed by Calpine into CCRC, or a subsidiary  controlled by CCRC,  sufficient
to total,  together  with the Net Proceeds,  an amount equal to the  outstanding
Bonds.

     On August 2, 2005, the Court issued its decision on the substantive merits.
The Court  dismissed the Harbert  Fund's  application  for relief and denied all
relief to the Harbert Fund and all other  bondholders that purchased Bonds on or
after  September  1, 2004.  However,  the Court  stated that a remedy  should be
granted to any bondholder,  other than the Calpine  respondent  companies,  that
purchased  Bonds prior to  September  1, 2004 and that  continues  to hold those
Bonds on August 2, 2005.

     The Court  directed  the Trustee to provide  the face amount of  qualifying
Bonds and the  identity  of the  holders of such Bonds by August 31,  2005.  The
Court stated that,  upon receipt of the  information  from the Trustee,  it will
then issue a final  order  requiring  Calpine to maintain in the control of CCRC
sufficient  proceeds  from the sale of Saltend to cover the face  amount of such
Bonds.  If there are  insufficient  proceeds for this  purpose,  Calpine will be
required to place in the control of CCRC an additional  amount which, when added
to the net Saltend sale  proceeds,  will cover the face value of all such Bonds.
The final order will  further  provide  that CCRC shall  diligently  conduct its
business  in a proper and  efficient  manner so as to  preserve  and protect its
business and assets.  Pending the final order, the Court issued an interim order
under which  Calpine must  maintain the net Saltend sale proceeds in the control
of CCRC.

     Any party to the  proceeding has the right to appeal the final order to the
Nova Scotia Court of Appeal.

     Harbert  Convertible   Arbitrage  Master  Fund,  Ltd.  et  al.  v.  Calpine
Corporation.  Plaintiff Harbert Convertible  Arbitrage Master Fund, Ltd. and two
affiliated  funds filed this action on July 11, 2005, in the Supreme Court,  New
York County, State of New York, and filed an amended complaint on July 19, 2005.
In  their  amended  complaint,  plaintiffs  allege  that,  on one or  more  days
beginning on July 1, 2005, the Trading Price of Calpine's 2014 Convertible Notes
was less than 95% of the  product of the Common  Stock Price  multiplied  by the
Conversion  Rate,  as those terms are defined in the  indenture  relating to the
2014  Convertible  Notes.  Plaintiffs  allege that they  provided  Calpine  with
reasonable   evidence  as  required  under  the  indenture  governing  the  2014
Convertible Notes that the Trading Price of the Notes on such date would be less
than the 95% threshold,  and that Calpine therefore was required to instruct the
Bid Solicitation  Agent for the 2014 Convertible  Notes to determine the Trading
Price  beginning on the next Trading Day. If the Trading  Price as determined by
the Bid  Solicitation  Agent were below 95% of the  product of the Common  Stock
Price multiplied by the Conversion Rate for five consecutive  Trading Days, then
the 2014 Convertible  Notes would become  convertible into cash and common stock
for a limited period of time.  Plaintiffs assert a claim for breach of contract,
seeking  unspecified  damages,  based  on  Calpine's  not  instructing  the  Bid
Solicitation  Agent  to begin to  calculate  the  Trading  Price.  In  addition,
plaintiffs seek  declaratory and injunctive  relief to force Calpine to instruct
the Bid  Solicitation  Agent  to  determine  the  Trading  Price  of the  Notes.
Plaintiffs  made, but later  withdrew,  a request for a preliminary  injunction.
Calpine intends to vigorously defend the action.

     SEC Informal Inquiry and Request for Documents and Information.  On June 9,
2005,  the Company  filed a Current  Report on Form 8-K with the SEC to disclose
that, in April 2005, the Division of Enforcement of the SEC informed the Company
that it was conducting an informal  inquiry and asked the Company to voluntarily
provide  documents  and  information  related  to:  (a) the  Company's  downward
revision  of its  proved  oil and gas  reserve  estimates  at  year-end  2004 as
compared to such estimates at year-end 2003, and a  corresponding  impairment of
the value of certain  assets,  all  previously  disclosed  by the  Company,  (b)
certain  statements made to various  regulatory  agencies by Michael  Portis,  a
terminated former employee, regarding the Company's determination of state sales
and use taxes,  and (c) the Company's  upward  restatement  in April 2005 of its
previously  disclosed  net income  for the third  quarter,  and the first  three
quarters,  of 2004. The Company is fully  cooperating with the SEC's request for
documents and information.

     In  addition,  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 its financial position or results of operations.


13.  Operating Segments

     The  Company is first and  foremost  an  electric  generating  company.  In
pursuing this  business  strategy,  it was the Company's  objective to produce a
portion of its fuel consumption  requirements  from its own natural gas reserves
("equity gas").  However, with the July 2005 sale of the Company's remaining oil
and gas  production and marketing  activity,  the Company now has one reportable
segment,  Electric Generation and Marketing. No other components of the business
had reached the  quantitative  criteria to be  considered a  reportable  segment
under  SFAS  No.  131.  See  Notes 8 and 15 for  discussions  of the sale of the
Company's oil and gas assets. Consequently, the revenue and expense from the Oil
and Gas Production and Marketing  reportable  segment has been  reclassified  to
discontinued  operations and the assets have been  reclassified into current and
long-term  assets held for sale.  The segment  has been  reflected  in the table
below within Corporate, Eliminations, and Other.

     Electric  Generation and Marketing  includes the development,  acquisition,
ownership  and operation of power  production  facilities,  hedging,  balancing,
optimization,  and trading activity  transacted on behalf of the Company's power
generation  facilities.  Corporate and other activities necessary to support the
Electric  Generation  and  Marketing  reporting  segment  consists  primarily of
financing   transactions,   activities  of  the  Company's  parts  and  services
businesses, and general and administrative costs.

14.  California Power Market

     California  Refund  Proceeding.  On August 2, 2000, the  California  Refund
Proceeding was initiated by a complaint made at FERC by San Diego Gas & Electric
Company under Section 206 of the Federal Power Act alleging, among other things,
that the markets  operated by the CAISO and the CalPX were  dysfunctional.  FERC
established a refund  effective period of October 2, 2000, to June 19, 2001 (the
"Refund Period"), for sales made into those markets.

     On December 12, 2002, an Administrative Law Judge issued a Certification of
Proposed Finding on California  Refund Liability  ("December 12  Certification")
making an initial  determination  of refund  liability.  On March 26, 2003, FERC
issued an order (the "March 26 Order")  adopting  many of the findings set forth
in the December 12 Certification.  In addition,  as a result of certain findings
by the FERC  staff  concerning  the  unreliability  or  misreporting  of certain
reported  indices for gas prices in California  during the Refund  Period,  FERC
ordered that the basis for calculating a party's  potential  refund liability be
modified  by  substituting  a gas  proxy  price  based  upon gas  prices  in the
producing areas plus the tariff transportation rate for the California gas price
indices  previously  adopted in the California  Refund  Proceeding.  The Company
believes,  based on information  that the Company has analyzed to date, that any
refund liability that may be attributable to it could total  approximately  $9.9
million (plus interest,  if applicable),  after taking the appropriate  set-offs
for outstanding  receivables owed by the CalPX and CAISO to Calpine. The Company
believes it has  appropriately  reserved  for the refund  liability  that by its
current  analysis  would  potentially  be  owed  under  the  refund  calculation
clarification  in the March 26  Order.  The final  determination  of the  refund
liability and the allocation of payment  obligations  among the numerous  buyers
and  sellers  in  the  California  markets  is  subject  to  further  Commission
proceedings.  It is possible that there will be further  proceedings  to require
refunds  from certain  sellers for periods  prior to the  originally  designated
Refund Period. In addition,  the FERC orders  concerning the Refund Period,  the
method for calculating refund liability and numerous other issues are pending on
appeal before the U.S. Court of Appeals for the Ninth Circuit. At this time, the
Company is unable to predict the timing of the  completion of these  proceedings
or the final refund  liability.  Thus,  the impact on the Company's  business is
uncertain.

     On April 26, 2004,  Dynegy Inc. entered into a settlement of the California
Refund  Proceeding and other proceedings with California  governmental  entities
and the three California  investor-owned  utilities. The California governmental
entities include the Attorney General, the CPUC, the CDWR, and the EOB. Also, on
April 27, 2004,  Williams  entered into a settlement  of the  California  Refund
Proceeding  and  other  proceedings  with the  three  California  investor-owned
utilities;  previously,  Williams  had  entered  into a  settlement  of the same
matters with the California  governmental entities. The Williams settlement with
the California  governmental entities was similar to the settlement that Calpine
entered  into with the  California  governmental  entities  on April  22,  2002.
Calpine's  settlement  resulted in a FERC order issued on March 26, 2004,  which
partially  dismissed Calpine from the California Refund Proceeding to the extent
that any refunds are owed for power sold by Calpine to CDWR or any other  agency
of the State of  California.  On June 30,  2004,  a  settlement  conference  was
convened  at the  FERC to  explore  settlements  among  additional  parties.  On
December  7,  2004,  FERC  approved  the  settlement  of the  California  Refund
Proceeding  and  other  proceedings  among  Duke  Energy   Corporation  and  its
affiliates,  the three California  investor-owned  utilities, and the California
governmental entities.

     FERC  Investigation  into  Western  Markets.  On February  13,  2002,  FERC
initiated an investigation of potential manipulation of electric and natural gas
prices in the western  United  States.  This  investigation  was  initiated as a
result of  allegations  that Enron and  others  used their  market  position  to
distort  electric  and  natural  gas  markets  in the  West.  The  scope  of the
investigation  is to consider  whether,  as a result of any  manipulation in the
short-term  markets for electric  energy or natural gas or other undue influence
on the wholesale  markets by any party since  January 1, 2000,  the rates of the
long-term contracts subsequently entered into in the West are potentially unjust
and  unreasonable.  On August 13, 2002, the FERC staff issued the Initial Report
on Company-Specific  Separate Proceedings and Generic  Reevaluations;  Published
Natural Gas Price Data;  and Enron Trading  Strategies  (the "Initial  Report"),
summarizing its initial findings in this  investigation.  There were no findings
or  allegations  of  wrongdoing by Calpine set forth or described in the Initial
Report.  On March  26,  2003,  the FERC  staff  issued  a final  report  in this
investigation  (the  "Final  Report").  In the  Final  Report,  the  FERC  staff
recommended  that  FERC  issue a show  cause  order  to a number  of  companies,
including  Calpine,  regarding certain power scheduling  practices that may have
been in  violation  of the  CAISO's or CalPX's  tariff.  The Final  Report  also
recommended  that FERC modify the basis for determining  potential  liability in
the California Refund Proceeding  discussed above.  Calpine believes that it did
not violate  these  tariffs and that, to the extent that such a finding could be
made, any potential liability would not be material.

     Also,  on June 25,  2003,  FERC issued a number of orders  associated  with
these investigations, including the issuance of two show cause orders to certain
industry participants.  FERC did not subject Calpine to either of the show cause
orders.  FERC also  issued an order  directing  the FERC  Office of Markets  and
Investigations  to investigate  further  whether market  participants  who bid a
price in excess of $250 per MWh into markets operated by either the CAISO or the
CalPX during the period of May 1, 2000,  to October 2, 2000,  may have  violated
CAISO and CalPX  tariff  prohibitions.  No  individual  market  participant  was
identified.  The  Company  believes  that it did not violate the CAISO and CalPX
tariff prohibitions  referred to by FERC in this order;  however, the Company is
unable to  predict  at this time the final  outcome  of this  proceeding  or its
impact on Calpine.

     CPUC  Proceeding  Regarding QF Contract  Pricing for Past  Periods.  Our QF
contracts  with PG&E  provide that the CPUC has the  authority to determine  the
appropriate  utility  "avoided  cost"  to be  used  to set  energy  payments  by
determining  the short run  avoided  cost  ("SRAC")  energy  price  formula.  In
mid-2000  our QF  facilities  elected the option set forth in Section 390 of the
California  Public  Utilities  Code,  which  provided  QFs the right to elect to
receive energy  payments based on the CalPX market clearing price instead of the
SRAC price administratively  determined by the CPUC. Having elected such option,
the  Company's  QF  facilities  were paid based upon the CalPX  zonal  day-ahead
clearing price ("CalPX Price") for various  periods  commencing in the summer of
2000 until January 19, 2001, when the CalPX ceased operating a day-ahead market.
The CPUC has conducted proceedings  (R.99-11-022) to determine whether the CalPX
Price was the  appropriate  price for the  energy  component  upon which to base
payments to QFs which had  elected  the  CalPX-based  pricing  option.  One CPUC
Commissioner  at one point  issued a proposed  decision  to the effect  that the
CalPX  Price  was the  appropriate  energy  price to pay QFs that  selected  the
pricing option then offered by Section 390. No final decision, however, has been
issued to date.  Therefore,  it is possible  that the CPUC could order a payment
adjustment based on a different energy price determination. On January 10, 2001,
PG&E filed an emergency motion (the "Emergency Motion") requesting that the CPUC
issue an order that would  retroactively  change the energy payments received by
QFs based on CalPX-based pricing for electric energy delivered during the period
commencing  during June 2000 and ending on January 18, 2001.  On April 29, 2004,
PG&E, the Utility Reform Network,  a consumer  advocacy group, and the Office of
Ratepayer  Advocates,  an independent  consumer advocacy  department of the CPUC
(collectively,  the  "PG&E  Parties"),  filed a  Motion  for  Briefing  Schedule
Regarding  True-Up of Payments to QF Switchers  (the "April 2004  Motion").  The
April 2004 Motion requests that the CPUC set a briefing  schedule in R.99-11-022
to determine what is the  appropriate  price that should be paid to the QFs that
had switched to the CalPX Price.  The PG&E Parties  allege that the  appropriate
price should be determined  using the  methodology  that has been developed thus
far in the California Refund Proceeding discussed above.  Supplemental pleadings
have been filed on the April 2004 Motion,  but neither the CPUC nor the assigned
administrative law judge has issued any rulings with respect to either the April
2004 Motion or the initial Emergency Motion. The Company believes that the CalPX
Price was the  appropriate  price for energy  payments  for its QFs during  this
period,  but there can be no assurance that this will be the outcome of the CPUC
proceedings.

     Geysers  Reliability  Must Run Section 206  Proceeding.  CAISO,  EOB, CPUC,
PG&E, San Diego Gas & Electric Company,  and Southern  California Edison Company
(collectively  referred  to as the  "Buyers  Coalition")  filed a  complaint  on
November 2, 2001 at FERC  requesting  the  commencement  of a Federal  Power Act
Section  206  proceeding  to  challenge  one  component  of a number of separate
settlements previously reached on the terms and conditions of RMR Contracts with
certain  generation  owners,   including  Geysers  Power  Company,   LLC,  which
settlements  were also  previously  approved by FERC. RMR Contracts  require the
owner of the specific  generation unit to provide energy and ancillary  services
when  called  upon to do so by the ISO to meet  local  transmission  reliability
needs or to manage transmission constraints. The Buyers Coalition has asked FERC
to find that the  availability  payments  under these RMR Contracts are not just
and reasonable.  Geysers Power Company,  LLC filed an answer to the complaint in
November  2001.  On June 3, 2005,  FERC  issued an order  dismissing  the Buyers
Coalition's  complaint against all named generation  owners,  including Geysers.
The Buyers'  Coalition  filed for  rehearing of FERC's order on July 5, 2005. On
August 2, 2005, FERC issued its Order Denying  Rehearing.  The proceeding is now
concluded at FERC.

15.  Subsequent Events

     On July 5, 2005 Calpine and Siemens  Westinghouse  ("Siemens")  executed an
agreement to settle various matters related to certain warranty  disputes and to
terminate  certain LTSA's.  Subsequent to the July 5, 2005 settlement  date, the
Company received approximately $25.5 million as a net settlement payment related
to these  matters,  a portion of which  related to events in existence  prior to
June 30,  2005.  Consequently,  $3.6  million of this amount was recorded in the
quarter ended June 30, 2005 as a reduction in plant operating  expense  relating
to warranty  recoveries  of prior  period  repair  expenses.  The  Company  also
recorded approximately $800,000 in additional LTSA expense in the period related
to the settlement agreement.  Generally the remained settlement proceeds will be
applied as a reduction  to  capitalized  turbine  costs in the third  quarter of
2005.

     On July 7, 2005, the Company  announced that it had signed a 15-year Master
Products and Services  Agreement  with GE, which is expected to lower  operating
costs in the future.  A related  agreement  replaces  the nine  remaining  LTSAs
related to Calpine's GE 7FA turbine fleet.  The Company  expects to benefit from
improved  power  plant  performance  and  valuable  operations  and  maintenance
flexibility  to service  its plants to further  lower  costs.  Historically,  GE
provided  full-service  turbine maintenance for a select number of Calpine power
plants.  Under the new agreement,  Calpine will supplement its operations with a
variety of GE services. Today, Calpine operates 44 power plants that are powered
by GE gas  turbines,  representing  approximately  10,000  MW of  capacity.  The
Company  recorded  LTSA  cancellation  expense  of $33.1  million  in the second
quarter of 2005 as a result of the LTSA cancellations.

     On July 7, 2005, the Company completed the sale of substantially all of its
remaining oil and gas exploration and production properties and assets for $1.05
billion,  less  approximately  $60  million of  estimated  transaction  fees and
expenses.  Approximately  $75 million of the purchase price was withheld pending
the  transfer  of  certain  properties  for  which  consents  have  not yet been
obtained. Furthermore, $142.7 million of the cash proceeds were used to purchase
$138.9  million of principal  amount (and pay $3.8  million of accrued  interest
expense) of the  outstanding  First Priority  Senior Secured Notes due 2014 (see
below for more information).

     On July 8, 2005, the Company  completed the sale of its 50% interest in the
175-MW  Grays  Ferry  power  plant to an  affiliate  of TNAI for $37.4  million.
Previously,  in the second quarter of 2005,  the Company  recorded an impairment
charge of $18.5  million in connection  with the facility.  The Company will use
net proceeds  from the sale in  accordance  with its existing  bond  indentures,
including for the repurchase of existing Company debt.

     On July 12, 2005,  the Company  announced that it had accepted for purchase
$138.9 million  aggregate  principal  amount of its  outstanding  First Priority
Notes under the terms of a tender offer  commenced June 9, 2005, to purchase for
cash any and all of the outstanding First Priority Notes. With completion of the
tender  offer,  the  Company  now has  approximately  $646.1  million  aggregate
principal amount of First Priority Notes outstanding.

     On July 13, 2005, the Company repaid the convertible  debentures payable to
Calpine  Capital  Trust  III,  the  issuer  of  the  HIGH  TIDES  III  preferred
securities.  The Trust then used the  proceeds  to redeem the  outstanding  HIGH
TIDES III preferred  securities totaling $517.5 million, of which $115.0 million
was held by Calpine.  The redemption price paid per each $50 principal amount of
HIGH  TIDES  III   preferred   securities   was  $50  plus  accrued  and  unpaid
distributions  to the  redemption  date in the  amount of $0.50.  All  rights of
holders of the HIGH TIDES III preferred securities have ceased, except the right
of such holders to receive the  redemption  price,  which was deposited with The
Depository Trust Company on July 13, 2005.

     On July 28, 2005,  the Company  completed  the sale of Saltend,  a 1,200-MW
power  plant in Hull,  England,  for a total  sale  price of  approximately  490
million British pounds,  or  approximately  $848 million,  plus  adjustments for
working  capital of $14.5  million,  resulting in total gross proceeds of $862.5
million.  Of this amount,  $647.1  million was used to redeem the $360.0 million
Two-Year  Redeemable  Preferred Shares issued by the Company's  Calpine Jersey I
subsidiary  on October 26, 2004,  and the $260.0  million  Redeemable  Preferred
Shares issued by the Company's Calpine Jersey II subsidiary on January 31, 2005,
including  interest  and  early  termination  fees of $16.3  million  and  $10.8
million,  respectively.  The remaining net proceeds will be used as permitted by
the Company's indentures.  As described further in Note 12, certain bond holders
filed a lawsuit  concerning  the  remaining use of the proceeds from the sale of
Saltend.

     On July 29,  2005,  the  Company  completed  the sale of its Inland  Empire
Energy Center development  project to GE, for approximately  $30.9 million.  The
project will be financed,  owned,  and operated by GE and will be used to launch
GE's most advanced gas turbine technology, the "H System (TM)." The Company will
manage  plant  construction,  market  the  plant's  output,  and manage its fuel
requirements.  The Company has an option to purchase the facility in years seven
through fifteen  following the commercial  operation date and GE can require the
Company to purchase the facility for a limited  period of time in the  fifteenth
year,  all  subject to  satisfaction  of various  terms and  conditions.  If the
Company  purchases  the  facility  under the call or put,  GE will  continue  to
provide critical plant maintenance  services  throughout the remaining estimated
useful life of the facility.

     On August 2, 2005,  the Company  completed  the sale of its interest in the
156-MW  Morris power plant to Diamond,  for $84.5  million.  Previously,  in the
second  quarter of 2005,  the  Company  had  determined  that the  facility  was
impaired at June 30, 2005, and recorded a charge to operations of $106.2 million
in the quarter ended June 30, 2005.  The Company's  assessment of impairment was
based on a  probability  weighting  of expected  future  cash  flows,  given the
alternatives  of selling or  continuing  to own and  operate the  facility.  Net
proceeds  from this asset  sale will be used in  accordance  with the  Company's
existing  bond  indentures.  See  Note  5  for a  discussion  of  the  Company's
impairment evaluation relating to the sale of Morris and Note 3 for a discussion
of possible additional material impairment charges relating to the sale of other
assets.

     On  August  3,  2005,  CCFC  I and  CCFC  Finance  Corp.  terminated  their
previously  announced tender offer for a portion of their Second Priority Senior
Secured  Floating Rate Notes due 2011. The offer was terminated  pursuant to the
conditions of the offer. The conditions provided,  among other things, that CCFC
I and CCFC Finance  Corp.  were not required to accept for payment,  purchase or
pay for any Floating  Rate Notes  tendered and were  permitted to terminate  the
offer if they did not expect to receive the net proceeds  from the proposed sale
of the  Ontelaunee  Energy Center on or prior to the tender offer purchase date.
CCFC I and CCFC Finance  Corp.  determined  that net proceeds from a sale of the
Ontelaunee  Energy  Center would not be received on or prior to the tender offer
purchase date, defined as no later than three business days following the tender
offer  expiration date of August 3, 2005, and accordingly  terminated the offer.
Any Floating Rate Notes  tendered in connection  with the offer were returned to
the  applicable  holders.  In addition,  CCFC did not accept for  purchase,  and
returned to lenders,  any and all First Priority  Senior  Secured  Institutional
Term Loans Due 2009 submitted in connection with CCFC's offer to repay such Term
Loans,  which  expired  on August 1,  2005.  The Term Loan  offer to repay  also
contained a  condition  with  respect to the receipt of the net  proceeds of the
sale of the Ontelaunee Energy Center.

     As a result  of  transactions  subsequent  to June 30,  2005,  the  Company
lowered its total debt by $1.3 billion to $17.4 billion at July 31, 2005.

Selected Operating Information

     Set forth below is certain  selected  operating  information  for our power
plants  for  which  results  are  consolidated  in  our  Consolidated  Condensed
Statements  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 revenues include, 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 steam sales and other thermal revenue.

     Defined  in EITF  Issue  No.  02-3:  "Issues  Involved  in  Accounting  for

     Consolidated  Condensed  Financial  Statements  for  a  discussion  of  our
     application of EITF Issue No. 03-11.
</FN>


     The primary reasons for the significant  levels of these sales and costs of
revenue  items  include:  (a)  significant  levels  of  hedging,  balancing  and
optimization   activities  by  our  CES  risk   management   organization;   (b)
particularly volatile markets for electricity and natural gas, which prompted us
to frequently  adjust our hedge  positions by buying power and gas and reselling
it; and (c) the accounting  requirements under SAB No. 101, "Revenue Recognition
in Financial Statements," and EITF Issue No. 99-19,  "Reporting Revenue Gross as
a  Principal  versus Net as an Agent,"  under  which we show many of our hedging
contracts on a gross basis (as opposed to netting sales and cost of revenue).

Overview

     Our core  business  and  primary  source of revenue is the  generation  and
delivery of electric  power.  We provide  power to our U.S.,  Canadian and other
customers through the integrated development,  construction or acquisition,  and
operation of efficient and environmentally friendly electric power plants fueled
primarily by natural gas and, to a much lesser degree, by geothermal  resources.
We  protect  and  enhance  the value of our  assets  with a  sophisticated  risk
management organization. We also protect our power generation assets and control
certain of our costs by producing certain of the combustion turbine  replacement
parts that we use at our power  plants,  and we  generate  revenue by  providing
combustion turbine parts to third parties.  Finally,  we offer services to third
parties to capture value in the skills we have honed in building, commissioning,
repairing and operating power plants.

      Our key opportunities and challenges include:

     o    preserving  and  enhancing  our  liquidity  while spark  spreads  (the
          differential between power revenues and fuel costs) are depressed,

     o    selectively  adding new  load-serving  entities and power users to our
          customer list as we increase our power contract portfolio,

     o    continuing  to  add  value  through   prudent  risk   management   and
          optimization activities, and

     o    lowering our costs of production through various efficiency programs.

     Since the latter half of 2001, there has been a significant  contraction in
the availability of capital for participants in the energy sector. This has been
due to a range of factors,  including  uncertainty  arising from the collapse of
Enron and a surplus  supply of electric  generating  capacity in certain  market
areas. These factors coupled with a three-year period of decreased spark spreads
have adversely impacted our liquidity and earnings.  We recognize that the terms
of  financing  available to us in the future may not be  attractive.  To protect
against this  possibility and due to current market  conditions,  we scaled back
our capital  expenditure  program to enable us to conserve our available capital
resources.  See "Capital  Availability" in Liquidity and Capital Resources below
for a further discussion.

     We  endeavor  to  improve  our  financial  strength.  On May 25,  2005,  we
announced a strategic initiative aimed at:

     o    Optimizing the value of our core North American power plant  portfolio
          by selling  certain  power and  natural  gas assets to reduce debt and
          lower  annual  interest  cost,  and to  increase  cash  flow in future
          periods.  At June 30, 2005, we had pending asset sales,  including the
          sale of Saltend in the United  Kingdom  (which was completed  July 28,
          2005), our interests in up to eight addition gas-fired power plants in
          the  United  States  (two of which were  completed  in July and August
          2005)  and our  remaining  oil  and  natural  gas  assets  (which  was
          completed  on July  7,  2005).  See  Notes  8 and 15 of the  Notes  to
          Consolidated Condensed Financial Statements.

     o    Taking  actions  to  decrease  operating  and  maintenance  costs  and
          lowering fuel costs to improve the operating  performance of our power
          plants,  which  would  boost  operating  cash flow and  liquidity.  In
          addition,  we are considering  temporarily shutting down certain power
          plants  with  negative  cash flow,  until  market  conditions  warrant
          starting  back  up,  to  further  reduce  costs.  See  Note  15  for a
          discussion of the restructuring of certain of our LTSAs.

     o    Reducing our collateral  requirements.  We and a financial institution
          are  discussing  a business  venture  that we  anticipate  would lower
          collateral requirements and enhance our third party customer business.

     o    Reducing total debt through the initiatives  listed above by more than
          $3 billion by the end of 2005 from debt levels at year end 2004, which
          we estimate would provide $275 million of annual interest savings.  As
          noted above, the cash and other consideration needed to reduce debt by
          that amount will be a function of the market value of debt repurchased
          in open market transactions and other factors.

     As a complement to our strategic  initiative  program,  we desire to expand
our third party  combustion  turbine  component parts and repair and maintenance
services business.

     The sale of our  remaining  oil and gas  assets in July 2005 to  Rosetta is
expected to increase the future  effective fuel expense (and lower spark spread)
for our fleet of  gas-fired  generating  plants by  eliminating  the  equity gas
benefit that we had enjoyed  from the fact that our costs of  producing  natural
gas were  significantly  lower than natural gas prices in recent years. Also, we
expect  that  purchasing  additional  volumes  from third party  producers  will
increase our  requirements  to post collateral or prepay for gas.  However,  the
negative  impacts on spark spread and gross profit (loss) will be offset to some
extent by lower interest expense in the future to the extent the proceeds of the
sale are used to repay debt. We also expect to use other  hedging  approaches in
managing our natural gas  requirements to compensate for the loss of the natural
hedge  position  that equity gas had afforded us. In the past when we sold fixed
price power,  we could use our equity gas reserves as a hedge against rising gas
prices. Other techniques have included purchase of fixed-for-floating  gas price
swap contracts,  purchasing  physical gas on a fixed-price basis, or potentially
buying back fixed price power  contracts.  In the future we will be more reliant
on these other techniques, the use of which may be limited by our current credit
constraints.  From a physical gas purchase  perspective,  we will be  purchasing
Rosetta's  California  production  at  market  prices  under  industry  standard
margining  provisions,  and we estimate that our  collateral  requirements  will
increase by approximately  $25 million for a typical payment cycle. From a fixed
price gas exposure perspective, we will not have any fixed price hedges in place
with Rosetta,  so our position will need to be managed with financial  swaps and
fixed price physical gas purchases. In addition, we may use proceeds of the sale
to purchase new natural gas assets as permitted by our indentures.

     Overview  of  Results -  Generation  volume was flat from the prior year as
mild weather in April and May dampened demand,  and we also  experienced  forced
outages at certain of our power  plants.  The  increase in total spark spread of
$38.6 million,  or 9%, in the three months ended June 30, 2005,  compared to the
same period in 2004 was not  commensurate  with the  increases  in  transmission
purchase expense,  depreciation,  and interest expense associated with new power
plants coming on line. Our average baseload capacity factor for the three months
ended June 30, 2005, was 39.9%.  However,  the baseload  capacity factor for the
month of June 2005  improved  to 43.5% as  demand  and  spark  spreads  began to
strengthen,  except in the West.  By July 2005 demand was  stronger in virtually
all of the  Company's  key  markets,  including  the  West,  and  spark  spreads
continued to improve.  Preliminarily,  we estimate  that our  baseload  capacity
factor for July was approximately 51%.

     Set forth below are the Results of Operations  for the three and six months
ended June 30, 2005 and 2004, which reflect  reclassifications  for discontinued
operations.  See  Note  8 of  the  Notes  to  Consolidated  Condensed  Financial

     Electricity and steam revenue  increased as the average  realized  electric
price before the effects of hedging, balancing and optimization,  increased from
$61.75 / MWh in 2004 to  $64.81  / MWh in  2005,  while  generation  volume  was
essentially flat between periods.

     We purchase transmission capacity so that power can move from our plants to
our customers.  Transmission capacity can be purchased on a long term basis and,
in many of the  markets  in which  the  company  operates,  can be resold if the
Company does not need it and some other party can use it. If the generation from
our  plants is less  than we  anticipated  when we  purchased  the  transmission
capacity,  we  can  realize  revenue  by  selling  the  unused  portion  of  the
transmission capacity.

     Sales of  purchased  power for hedging and  optimization  decreased  in the
three months  ended June 30, 2005,  due  primarily to lower  volumes  which were
partially offset by higher prices, as compared to the same period in 2004.

     The  Company   reclassified   its  remaining  oil  and  gas  operations  to
discontinued  operations  ("held for sale") in the quarter  ended June 30, 2005.
Activity in prior years relates to minor assets sold in prior years that did not
meet the criteria for reclassification to discontinued operations at the time of
sale. See Note 8 of the Notes to Consolidated Condensed Financial Statements for
more information.

     Sales of purchased gas for hedging and  optimization  decreased during 2005
due primarily to lower volumes  offset by higher  liquidation  prices of natural
gas compared to the same period in 2004. The sale of our remaining  Canadian oil
and gas assets in 2004, combined with reduced gas procurement, decreased volumes
available for resale during 2005 as compared to 2004.

     Mark-to-market  activities,  which are shown on a net  basis,  result  from
general market price movements against our open commodity derivative  positions,
including  positions accounted for as trading under EITF Issue No. 02-3, "Issues
Related  to  Accounting  for  Contracts  Involved  in  Energy  Trading  and Risk
Management  Activities"  and other  mark-to-market  activities.  These commodity
positions  represent a small portion of our overall commodity contract position.
Realized  revenue  represents the portion of contracts  actually  settled and is
offset by a  corresponding  change in  unrealized  gains or losses as unrealized
derivative  values are converted from  unrealized  forward  positions to cash at
settlement. Unrealized gains and losses include the change in fair value of open
contracts as well as the ineffective portion of our cash flow hedges.

     The net gain from mark-to-market  activities in the three months ended June
30,  2005,  as  compared to the same  period in 2004 is due  primarily  to gains
relating to our Deer Park  transaction  which is  recorded  on a  mark-to-market
basis, and the non-recurrence of a loss on a derivative contract that terminated
in 2004.

     Plant operating  expense  decreased  primarily due to certain  property tax
rebates and favorable reassessments,  recovery of a warranty claim, general cost
cutting initiatives and timing of major maintenance  spending versus prior year.
These  factors  were  partially  offset from the costs of  additional  plants in
operation.  Transmission  purchase  expense  increased  mostly due to additional
power plants achieving commercial operation subsequent to June 30, 2004.

     Royalty expense increased primarily due to an increase in electric revenues
at The Geysers  geothermal plants and due to an increase in contingent  purchase
price  payments  to the  previous  owners of the Texas City and Clear Lake power
plants,  which are based on a percentage of gross revenues at the plants. At The
Geysers,  royalties are paid mostly as a percentage  of  geothermal  electricity
revenues.

     Purchased power expense for hedging and  optimization  decreased during the
three  months  ended June 30,  2005,  as compared to the same period in 2004 due
primarily to a reduction in volumes as compared to the same period in 2004.

     Fuel expense  increased  during the three  months  ended June 30, 2005,  as
compared to the same period in 2004 due primarily to higher natural gas prices.

     Depreciation, depletion and amortization expense increased primarily due to
the additional  power facilities in consolidated  operations  subsequent to June
30, 2004.

results,  including this impairment  charge,  to discontinued  operations in the
third quarter of 2005.

Operating lease expense....................................................  $       25.5  $       27.0  $        1.5         5.6%


     Operating  lease  expense   decreased  from  the  prior  year  due  to  the
restructuring  of the King City lease in May 2004. After the  restructuring,  we
began to account  for the King City lease as a capital  lease.  As a result,  we
stopped incurring  operating lease expense at that facility and instead began to
incur depreciation and interest expense.

Other cost of revenue......................................................  $       32.1  $       22.6  $       (9.5)      (42.0)%


     Other cost of revenue  increased  during  the three  months  ended June 30,
2005,  as  compared  to the same period in 2004,  due to  increased  gas turbine
maintenance  services  activity at TTS and increased gas turbine component sales
by PSM.

     The increase in income was  primarily due to an increase in income from the
Acadia PP  investment  (due mostly to lower major  maintenance  costs),  and the
non-recurrence  of losses recorded in 2004 from our investments in the Aries and
AELLC power  plants.  In March 2004,  we purchased the remaining 50% interest in
the Aries power plant (at which time this plant was  consolidated) and we ceased
to recognize our share of the operating  results of AELLC as we began to account
for our  investment in AELLC using the cost method  following  loss of effective
control when AELLC filed for bankruptcy protection in November 2004.

     Sales, general and administrative expense increased during the three months
ended June 30, 2005,  primarily due to an increase in legal fees,  franchise tax
fees and employee compensation costs.

Interest expense...........................................................  $333.8        $      270.6  $      (63.2)      (23.4)%


     Interest expense increased primarily as a result of higher average interest
rates  and  lower  capitalization  of  interest  expense.  Interest  capitalized
decreased from $102.2 for the three months ended June 30, 2004, to $64.2 for the
three months ended June 30, 2005, as new plants  entered  commercial  operations
(at which  point  capitalization  of  interest  expense  ceases)  and because of
suspended  capitalization of interest on three partially completed  construction
projects.  We expect that the amount of interest  capitalized  will  continue to
decrease in future periods as our plants in construction  are completed.  During
the three months ended June 30, 2005, (i) interest expense related to our Senior
Notes,  contingent  convertible  notes,  and term loans  increased by $9.1; (ii)
interest  expense  related  to our  CalGen  subsidiary  increased  $11.4;  (iii)
interest  expense  related to our  construction/project  financing  increased by
$14.7; (iv) interest expense related to our CCFC I subsidiary increased by $3.3;
and (v)  interest  expense  related to  preferred  interests  increased by $19.8
primarily  due to the October  2004 closing of the $360  offering of  redeemable
preferred securities by our indirect subsidiary,  Calpine Jersey I, and the $260
offering on January 31, 2005, of redeemable preferred securities by our indirect
subsidiary,  Calpine  Jersey II. These  interest  cost  increases  are partially
offset by a decrease of $8.8 in interest  expense on the convertible  debentures
payable to the Calpine Capital Trusts, which have been redeemed.

     Interest (income)  increased during the six months ended June 30, 2005, due
primarily  to  higher  interest  earned on margin  deposits  and  collateralized
letters of credit and due to higher interest rates.

Minority interest expense (income).........................................  $       10.2  $        4.7  $       (5.5)     (117.0)%


     Minority  interest expense increased during the three months ended June 30,
2005,  as compared to the same  period in 2004  primarily  due to an increase in
income at CPLP,  which is 70% owned by CPIF.  The  variance is largely due to an
increase  in  availability  at the  Island  Cogen  plant in 2005 as a result  of
 non-recurrence of major maintenance work performed during 2004.


                                                                                  Three Months Ended

     The increase in income from repurchases of various issuances of debt is due
to  considerably  higher  volumes of Senior Notes during 2005. See Note 7 of the
Notes to Consolidated Condensed Financial Statements for further information.

Other expense (income), net................................................  $       25.8  $     (179.5) $     (205.3)     (114.4)%


     The net expense for the three months ended June 30, 2005 was  primarily due
to an  impairment  charge of $18.5  related to our  investment  in Grays  Ferry.
Additionally,  we wrote  off $5.8 of  unamortized  deferred  financing  costs in
connection with the  refinancing of the Metcalf  project debt.  These items were
partially offset by a gain in foreign  exchange  transaction  activities,  which
represented a favorable  variance of $16.3 from the prior year. Other income for
the quarter ended June 30, 2004, included gains of $171.5 from the restructuring
and sale of power purchase  agreements for two of our New Jersey plants,  net of
transaction costs and the write-off of unamortized deferred financing costs.

Benefit for income taxes...................................................  $     (134.9) $      (48.2) $       86.7       179.9%


     During the three months ended June 30, 2005,  our tax benefit  increased by
$86.7 as compared to the three  months  ended June 30, 2004 as our pre-tax  loss
increased in 2005. The effective tax rate decreased to 32.7% in 2005 compared to
39.5% in the same period in 2004 largely due to additional  valuation allowances
against deferred tax assets in 2005, thus reducing the tax benefit.

Discontinued operations, net of tax provision..............................  $      (20.5) $       45.0  $      (65.5)     (145.6)%


     The discontinued  operations in the three months ended June 30, 2005, are a
result of the sales of Saltend and  substantially  all of our  remaining oil and
gas  assets.  Both  of  these  dispositions  closed  in July  2005,  but met the
discontinued  operations  criteria  as of June 30,  2005,  under  SFAS No.  144.
Discontinued  operations for the three months ended June 30, 2004, also included
the Lost Pines I Power Project and oil and gas dispositions in 2004.

Net loss...................................................................  $     (298.5) $      (28.7) $     (269.8)     (940.1)%


     For the three  months  ended June 30,  2005,  we  reported  revenue of $2.2
billion,  representing  an  increase  of 0.5% over the same  period in the prior
year.  Including the discontinued  operations discussed below, we recorded a net
loss per share of $0.66,  or a net loss of  $298.5,  compared  to a net loss per
share of $0.07, or a net loss of $28.7, for the same quarter in the prior year.

     Included in the current  quarter's results are various  non-routine  items,
which are discussed in more detail below and in the aggregate netted to a charge
of $0.11 per share,  consisting  of  impairment  charges on two power  plants in
operation and three in development,  cancellation  charges to terminate  several
LTSAs, and a net gain on the repurchase of debt.

     For the three months ended June 30, 2005, our average capacity in operation
for consolidated projects increased by 10.9% to 25,566 MW. Generation volume was
flat from the prior year as mild weather in April and May decreased demand,  and
we also experienced  forced outages at certain of our power plants. We generated
approximately  20.0 million MWh, which equated to a baseload  capacity factor of
39.9%,  and realized an average spark spread of $22.57/MWh.  For the same period
in 2004, we generated  20.1 million MWh,  which  equated to a baseload  capacity
factor of 45.0%, and realized an average spark spread of $20.62/MWh.

     Gross  profit  (loss)  decreased  by $58.8 to a loss of $31.5 in the  three
months ended June 30, 2005,  compared to the same period in the prior year. This
change is due primarily to a $106.2 impairment  charge related to Morris,  which
sale was pending at the end of the quarter.  Although  total spark spread margin
increased  by  $38.6  period-to-period,  it did not  increase  in line  with the
increases in transmission  purchase  expense,  depreciation and interest expense
associated with new power plants coming on line.

     During  the three  months  ended  June 30,  2005,  financial  results  were
positively  impacted by $129.2 of income  recorded  from  repurchase  of various
issuances of debt and negatively impacted by $33.9 in LTSA cancellation charges.
In  addition,  we  recorded  $45.5 in  project  development  expense  due to the
write-off of three projects in suspended development. Interest expense increased
$63.2 between periods  primarily due to an increase in the average interest rate
and lower  capitalization  of  interest  expense as fewer  plants were in active
construction.

     Other expense was $25.8 for the three months ended June 30, 2005,  compared
to other  income of $179.5 for the three  months  ended June 30,  2004.  The net
expense  for the  three  months  ended  June  30,  2005,  was due  mainly  to an
impairment  charge of $18.5 on our  investment in Grays Ferry.  Other income for
the  quarter  ended June 30,  2004,  included  $171.5 in pre-tax  gains from the
restructuring  and sale of power  purchase  agreements for two of our New Jersey
plants,  net of  transaction  costs and the  write-off of  unamortized  deferred
financing costs.

     The discontinued  operations in the three months ended June 30, 2005, are a
result of the sale of Saltend and substantially all of our remaining oil and gas
exploration and production  properties and assets. Both of these sales closed in
July 2005, which met the discontinued  operations  criteria as of June 30, 2005,
under SFAS No. 144. Discontinued  operations for the three months ended June 30,
2004,  also  included  the Lost Pines I Power  Project  and oil and gas sales in
2004.

     Electricity and steam revenue  increased as average megawatts in operations
of our  consolidated  plants  increased  by 16.0% to 25,330 MW while  generation
increased  by 3.5%.  In addition,  average  realized  electric  price before the
effects of hedging,  balancing and optimization,  increased from $61.28 / MWh in
2004 to $64.31 / MWh in 2005.

     We purchase transmission capacity so that power can move from our plants to
our customers.  Transmission capacity can be purchased on a long term basis and,
in many of the  markets  in which  the  company  operates,  can be resold if the
Company does not need it and some other party can use it. If the generation from
our  plants is less  than we  anticipated  when we  purchased  the  transmission
capacity,  we  can  realize  revenue  by  selling  the  unused  portion  of  the
transmission capacity.

     Sales of purchased power for hedging and optimization  decreased in the six

offset by higher prices, as compared to the same period in 2004.

     We  reclassified  our  remaining  oil and gas  operations  to  discontinued
operations ("held for sale") in the six months ended June 30, 2005.  Activity in
prior  years  relates to minor  assets sold in prior years that did not meet the
criteria for  reclassification  to discontinued  operations at the time of sale.
See Note 8 of the Notes to Consolidated  Condensed Financial Statements for more
information.

     Sales of purchased gas for hedging and  optimization  increased during 2005
due  primarily  to higher  prices of natural gas  compared to the same period in
2004.

     Mark-to-market  activities,  which are shown on a net  basis,  result  from
general market price movements against our open commodity derivative  positions,
including  positions accounted for as trading under EITF Issue No. 02-3, "Issues
Related  to  Accounting  for  Contracts  Involved  in  Energy  Trading  and Risk
Management  Activities"  and other  mark-to-market  activities.  These commodity
positions  represent a small portion of our overall commodity contract position.
Realized  revenue  represents the portion of contracts  actually  settled and is
offset by a  corresponding  change in  unrealized  gains or losses as unrealized
derivative  values are converted from  unrealized  forward  positions to cash at
settlement. Unrealized gains and losses include the change in fair value of open
contracts as well as the ineffective portion of our cash flow hedges.

     The  decrease  in losses in  mark-to-market  activities  revenue in the six
months  ended  June 30,  2005 is  attributable  largely  to  gains on  commodity
deliveries to MLCI from Deer Park, a wholly owned subsidiary of the Company, and
to decreases in liquidity reserves on our mark-to-market positions.

     Other revenue  increased due primarily to higher revenues at PSM associated
with sales of gas  turbine  components  and at TTS for gas  turbine  maintenance
services.

     Plant operating  expense  decreased  primarily due to certain  property tax
rebates and favorable reassessments,  recovery of a warranty claim, general cost
cutting initiatives and timing of major maintenance  spending versus prior year.
Transmission  purchase  expense  increased mostly due to additional power plants
achieving  commercial operation subsequent to June 30, 2004, and to increases in
western area transmission fees.

     Royalty expense increased primarily due to an increase in electric revenues
at The Geysers  geothermal plants and due to an increase in contingent  purchase
price  payments  to the  previous  owners of the Texas City and Clear Lake power
plants,  which are based on a percentage of gross revenues at the plants. At The
Geysers,  royalties are paid mostly as a percentage  of  geothermal  electricity
revenues.

     Purchased power expense for hedging and  optimization  decreased during the
six months  ended June 30,  2005,  as  compared  to the same  period in 2004 due
primarily to a reduction in volumes as compared to the same period in 2004.

     The  Company   reclassified   its  remaining  oil  and  gas  operations  to
discontinued operations ("held for sale") in the six months ended June 30, 2005.
Remaining  activity in continuing  operations  relates primarily to gas pipeline
activities  which were not sold and  activity in prior years also  includes  the
results of minor  assets sold in prior years that did not meet the  criteria for

the Notes to Consolidated Condensed Financial Statements for more information.

     Purchased gas expense for hedging and optimization increased during the six
months ended June 30, 2005,  due to higher natural gas prices as compared to the

Operating lease expense....................................................  $       50.3  $       54.8  $        4.5         8.2%


     Operating  lease  expense   decreased  from  the  prior  year  due  to  the
restructuring  of the King City lease in May 2004.  After the  restructuring  we
began to account  for the King City lease as a capital  lease.  As a result,  we
stopped incurring  operating lease expense at that facility and instead began to
incur depreciation and interest expense.

     Other cost of revenue  increased during the six months ended June 30, 2005,
as compared to the same period in 2004,  due primarily to $19.2 for  transaction
costs  incurred on the closing of an agreement to sell power to and buy gas from
MLCI. See Note 9 of the Notes to Consolidated Condensed Financial Statements for

     The increase in income was  primarily due to an increase in income from the
Acadia PP  investment  (mostly due to lower  major  maintenance  costs),and  the
non-recurrence  of losses recorded in 2004 from our investments in the Aries and
AELLC power  plants.  In March 2004,  we purchased the remaining 50% interest in
the Aries power plant (at which time this plant was  consolidated) and we ceased
to recognize our share of the operating  results of AELLC as we began to account
for our  investment in AELLC using the cost method  following  loss of effective
control when AELLC filed for bankruptcy protection in November 2004.

     Research and development expense increased during the six months ended June
30,  2005,  as compared to the same period in 2004  primarily  due to  increased
personnel expenses,  and consulting fees related to new research and development

     Sales,  general and administrative  expense increased during the six months

fees and write-off of tenant improvement costs related to excess office space.

Interest expense...........................................................  $      658.4  $      516.2  $     (142.2)      (27.5)%


     Interest expense increased primarily as a result of higher average interest
rates  and  lower  capitalization  of  interest  expense.  Interest  capitalized
decreased  from $210.7 for the six months ended June 30, 2004, to $134.4 for the
six months ended June 30, 2005, as new plants entered commercial  operations (at
which point  capitalization of interest expense ceases) and because of suspended
capitalization of interest on three partially completed  construction  projects.
We expect that the amount of interest  capitalized  will continue to decrease in
future  periods  as our plants in  construction  are  completed.  During the six
months ended June 30, 2005,  (i) interest  expense  related to our Senior Notes,
contingent  convertible  notes, and term loans increased by $18.7; (ii) interest
expense related to our CalGen subsidiary increased $24.8; (iii) interest expense
related to our construction/project  financing increased by $31.4; (iv) interest
expense  related to our CCFC I subsidiary  increased  by $5.5;  and (v) interest
expense related to preferred  interests  increased by $33.4 primarily due to the
October 2004 closing of the $360 offering of redeemable  preferred securities by
our indirect subsidiary,  Calpine Jersey I, and the $260 offering on January 31,
2005, of redeemable  preferred  securities by our indirect  subsidiary,  Calpine
Jersey II.  These  increases  in interest  expense are  partially  offset by the
decrease  in interest  expense of $17.7  related to the  convertible  debentures
payable to the Calpine Capital Trusts, which have been redeemed.

Interest (income)..........................................................  $      (30.8) $      (21.0) $        9.8        46.7%


     Interest (income)  increased during the six months ended June 30, 2005, due
primarily  to  higher  interest  earned on margin  deposits  and  collateralized
letters of credit and due to higher interest rates.

Minority interest expense..................................................  $       20.8  $       13.2  $       (7.6)      (57.6)%


     Minority  interest  expense  increased during the six months ended June 30,
2005,  as compared to the same  period in 2004  primarily  due to an increase in
income at CPLP,  which is 70% owned by CPIF.  The  variance is largely due to an
increase  in  availability  at the  Island  Cogen  plant in 2005 as a result  of
non-recurrence of major maintenance work performed during 2004.


                                                                                   Six  Months Ended

     Income from repurchases of various issuances of debt is due to considerably
higher volumes of Senior Notes repurchased  during 2005. See Note 7 of the Notes
to Consolidated Condensed Financial Statements for further information.

Other expense (income), net................................................  $       20.8  $     (191.4) $     (212.2)     (110.9)%


     Other expense was $20.8 for the six months ended June 30, 2005, compared to
other income of $191.4 for the six months  ended June 30, 2004.  The net expense
for the six months  ended June 30,  2005,  was  primarily  due to an  impairment
charge of $18.5 related to our investment in Grays Ferry.  Additionally,  we had
$6.4 higher letter of credit fees and we wrote off $5.8 of unamortized  deferred
financing  costs in connection with the refinancing of the Metcalf project debt.
These  items were  partially  offset by a gain in foreign  exchange  transaction
activities, which represented a favorable variance of $20.8 from the prior year.
Other income for the six months ended June 30,  2004,  included  gains of $171.5
from the restructuring and sale of power purchase  agreements for two of our New
Jersey  plants,  net of  transaction  costs  and the  write-off  of  unamortized
deferred financing costs.


                                                                                   Six  Months Ended

Benefit for income taxes...................................................  $     (233.6) $     (143.2) $       90.4        63.1%


     During the six months  ended June 30,  2005,  our tax benefit  increased by
$90.4 as  compared to the six months  ended June 30,  2004 as our  pre-tax  loss
increased in 2005. The effective tax rate decreased to 33.8% in 2005 compared to
39.0% in the same period in 2004 largely due to additional  valuation allowances
against deferred tax assets in 2005, thus reducing the tax benefit.


                                                                                   Six  Months Ended

Discontinued operations, net of tax........................................  $       (9.8) $      124.3  $    (134.1)      (107.9)%


     The  discontinued  operations in the six months ended June 30, 2005,  are a
result of the July 2005 sales of Saltend and  substantially all of our remaining
oil and gas assets.  The sales met the  discontinued  operations  criteria as of
June 30, 2005.  Discontinued  operations for the six months ended June 30, 2004,
also  included the Lost Pines 1 Power  Project and oil and gas  dispositions  in
2004. In 2004,  we  recognized  pre-tax gains on the sale of Lost Pines of $35.3
and on certain oil and gas dispositions of $3.6. Additionally,  operating income
was  significantly  higher at Saltend  and from oil and gas  operations  in 2004
compared to 2005.


                                                                                   Six  Months Ended

Net loss...................................................................  $     (467.2) $      (99.9) $     (367.3)     (367.7)%


     For the six  months  ended  June 30,  2005,  we  reported  revenue  of $4.3
billion,  representing  an  increase  of 4.2% over the same  period in the prior
year. Including the discontinued operations, we recorded a net loss per share of
$1.04, or a net loss of $467.2,  compared to a net loss per share of $0.24, or a
net loss of $99.9, for the same period in the prior year.

     Included in the six-months results are various non-routine items, which are
discussed in more detail below and in the aggregate  netted to a charge of $0.08
per share, consisting of impairment charges on two power plants in operation and
three in development, cancellation charges to terminate several LTSAs, and a net
gain on the repurchase of debt.

     For the six months ended June 30, 2005,  our average  capacity in operation
for  consolidated  projects  increased  by  16.0% to  25,330  MW.  We  generated
approximately  40.1 million MWh, which equated to a baseload  capacity factor of
40.6%,  and realized an average spark spread of $22.61/MWh.  For the same period
in 2004,  Calpine  generated  38.7  million  MWh,  which  equated  to a baseload
capacity factor of 46.2%, and realized an average spark spread of $19.75/MWh.

     Gross profit (loss)  decreased by $24.8, or 34%, to $48.3 in the six months
ended June 30, 2005,  compared to the same period in the prior year. This change
is due  primarily  to a $106.2  impairment  charge  related to  Morris.  Despite
improvements  in market  fundamentals,  total spark spread - which  increased by
$144.8,  or 19%,  in the six months  ended June 30,  2005,  compared to the same
period in 2004 - did not increase in line with the increases in plant  operating
expense,  transmission  purchase  expense,  depreciation,  and interest  expense
associated with new power plants coming on line.

     During  the  six  months  ended  June  30,  2005,  financial  results  were
positively  impacted by $150.9 of income  recorded  from  repurchase  of various
issuances of debt and negatively impacted by $33.9 in LTSA cancellation charges.
In  addition,  we  recorded  $45.5 in  project  development  expense  due to the
write-off of three projects in suspended development. Interest expense increased
$142.2 between periods primarily due to an increase in the average interest rate
and lower  capitalization  of  interest  expense as fewer  plants were in active
construction.

     Other expense was $20.8 for the six months ended June 30, 2005, compared to
other income of $191.4 for the six months  ended June 30, 2004.  The net expense
for the six months ended June 30, 2005,  was due mainly to an impairment  charge
of $18.5  related to our  investment  in Grays  Ferry.  Other income for the six
months  ended  June  30,  2004,  included  $171.5  in  pre-tax  gains  from  the
restructuring  and sale of power  purchase  agreements for two of our New Jersey
plants,  net of  transaction  costs and the  write-off of  unamortized  deferred
financing costs.

     The  discontinued  operations in the six months ended June 30, 2005,  are a
result of the July 2005 sales of Saltend and  substantially all of our remaining
oil and natural gas assets which met discontinued operations criteria as of June
30, 2005..  Discontinued operations for the six months ended June 30, 2004, also
included the Lost Pines 1 Power Project and oil and gas sales in 2004.

Liquidity and Capital Resources

     Our  business is capital  intensive.  Our ability to  capitalize  on growth
opportunities  and to service  the debt we incurred  in order to  construct  and
operate  our  current  fleet of  power  plants  is  dependent  on the  continued
availability of capital on attractive terms. The availability of such capital in
today's  environment  is  uncertain.  To date,  we have  obtained  cash from our
operations; borrowings under credit facilities; issuances of debt, equity, trust
preferred  securities and  convertible  debentures  and  contingent  convertible
notes;  proceeds  from  sale/leaseback  transactions;  sale or  partial  sale of
certain assets;  prepayments received for power sales;  contract  monetizations;
and  project  financings.  We have  utilized  this cash to fund our  operations,
service,  repay or refinance debt obligations,  fund  acquisitions,  develop and
construct power generation facilities, finance capital expenditures, support our
hedging, balancing, optimization and trading activities, and meet our other cash
and liquidity needs.

     Capital  Availability  -- Access to capital for many in the energy  sector,
including us, has been  restricted  since late 2001.  While we have been able to
access the capital and bank credit markets in this new environment,  it has been
on  significantly  different  terms than before 2002. In particular,  our senior
working  capital  facilities  and term loan  financings  entered  into,  and the
majority of our debt securities  offered and sold by us in this period have been
secured by certain of our assets and subsidiary equity  interests.  We have also
provided  security  to  support  our  prepaid  commodity  transactions.  In  the
aggregate, the average interest rate on our new debt instruments,  especially on
debt  incurred  to  refinance  existing  debt,  has been  higher.  The  terms of
financing available to us now and in the future may not be attractive to us. The
timing of the availability of capital is uncertain and is dependent, in part, on
market conditions that are difficult to predict and are outside of our control.

     In addition, satisfying all obligations under our outstanding indebtedness,
and funding  anticipated capital  expenditures and working capital  requirements
for the next twelve months and potentially, thereafter, presents us with several
challenges as our cash requirements (including our refinancing  obligations) are
expected to exceed the sum of our cash on hand  permitted  to be used to satisfy
such  requirements  and cash from  operations.  Accordingly,  we have in place a
strategic  initiative which includes  possible sales or monetizations of certain
of our  assets.  Whether we will have  sufficient  liquidity  will depend on the
success of that  program.  No  assurance  can be given that our program  will be
successful.  If it is not  successful,  additional  asset  sales,  refinancings,
monetizations   and  other  actions  beyond  those  included  in  the  strategic
initiative  would  likely  need  to  be  made  or  taken,  depending  on  market
conditions.  Our  ability  to reduce  debt will also  depend on our  ability  to
repurchase debt securities through open market  transactions,  and the principal
amount of debt able to be repurchased  will be contingent upon market prices and
other factors. Even if the program is successful, there can be no assurance that
we will be able to continue  work on our projects in  development  and suspended
construction  that have not been  successfully  project  financed,  and we could
possibly incur substantial  impairment losses as a result. In addition,  even if
the strategic  initiative is successful,  until there are significant  sustained
improvements  in spark spreads,  we expect that we will not have sufficient cash
flow from operations to repay all of our indebtedness at maturity or to fund our
other liquidity needs. We expect that we will need to extend or refinance all or
a portion of our indebtedness, on or before maturity. While we currently believe
that we will be  successful  in repaying,  extending or  refinancing  all of our
indebtedness on or before maturity, we cannot assure you that we will be able to
do so or that the terms of any such extension or refinancing will be attractive.
For further  discussion  of this see the risk  factors in our 2004 Form 10-K and
our Current Report on Form 8-K filed with the SEC on July 1, 2005.

Transactions Completed in the Three Months Ended June 30, 2005:

     o    Repurchased  in open market  transactions  $479.8 million in principal
          amount of our outstanding debt. The securities,  which were trading at
          a discount to par value,  were  repurchased for  approximately  $337.9
          million in cash plus accrued  interest.  We recorded a $137.5  million
          gain as a result of these  repurchases  after write-off of unamortized
          deferred financing costs and unamortized discounts.  See Note 7 of the
          Notes  to  Consolidated   Condensed  Financial   Statements  for  more
          information.

     o    Received  funding for Metcalf's  $155.0  million  offering of 5.5-Year
          Redeemable Preferred Shares and five-year,  $100.0 million Senior Term
          Loan. A portion of the net  proceeds  was used to repay $50.0  million
          outstanding  on the  original  Metcalf  project  financing,  with  the
          remaining  net  proceeds  to be  used  as  permitted  by our  existing
          indentures.  See  Note  7  of  the  Notes  to  Consolidated  Condensed
          Financial Statements for more information.

     o    Received funding for our $123.1 million,  non-recourse project finance
          facility to complete the  construction of the 79.9-MW  Bethpage Energy
          Center 3.  Approximately  $55.0  million  of the  funding  was used to
          reimburse  us for costs spent to date on the  project.  An  additional
          amount of approximately $11.2 million will be released upon satisfying
          certain conditions.  The balance of funds will be used for transaction
          expenses,  the final  completion  of the project  and to fund  certain
          reserve  accounts.  See Note 7 of the Notes to Consolidated  Condensed
          Financial Statements for more information.

     o    Issued $650.0 million in principal amount of 2015 Convertible Notes in
          June 2005.  In July 2005,  we used a portion  of the net  proceeds  to
          redeem the $517.5 million in principal  amount  outstanding of 5% HIGH
          TIDES III preferred  securities,  of which $115.0  million was held by
          us. We used the  remaining net proceeds to repurchase a portion of the
          outstanding  principal amount of our 8 1/2% Senior Notes due 2011. See
          Notes  7 and 11 of  the  Notes  to  Consolidated  Condensed  Financial
          Statements for more information.

     o    Repurchased  $94.3  million in  principal  amount at  maturity of 2014
          Convertible  Notes in  exchange  for 27.5  million  shares of  Calpine
          common  stock.  We  recorded  a pre-tax  loss of $7.9  million  on the
          exchange,  which includes the write-off of the associated  unamortized
          deferred financing costs and unamortized original issue discount.  See
          Note 7 of the Notes to Consolidated Condensed Financial Statements for
          more information.

     For the three months ended June 30, 2005, we recorded an aggregate  pre-tax
gain  of  $137.5  million  on the  above  repurchases  after  the  write-off  of
unamortized deferred financing costs and unamortized discounts.

     Transactions  Completed  Subsequent  to June 30,  2005  (See Note 15 of the
Notes to Consolidated Condensed Financial Statements for more information):

     o    Sold  all of our  remaining  domestic  oil  and  gas  exploration  and
          production  properties and assets for $1.05 billion, less adjustments,
          transaction fees and expenses,  and less  approximately $75 million to
          reflect the value of certain oil and gas  properties for which we were
          unable to obtain consents to assignment prior to closing. We expect to
          receive the remaining consents in the near future.

     o    Completed  the  sale of  Saltend,  a  1,200-MW  power  plant  in Hull,
          England,  generating  total gross proceeds of $862.5 million.  Of this
          amount,  approximately  $647.1  million  was used to redeem the $360.0
          million  Two-Year  Redeemable  Preferred  Shares issued by our Calpine
          Jersey I  subsidiary  on October  26,  2004,  and the  $260.0  million
          Redeemable Preferred Shares issued by our Calpine Jersey II subsidiary
          on January 31, 2005,  including interest and termination fees of $16.3
          million and $10.8 million,  respectively. As described further in Note
          12,  certain  bondholders  filed a lawsuit  concerning  the use of the
          proceeds remaining from the sale of Saltend.

     o    Sold our 50%  interest  in the 175-MW  Grays  Ferry  power plant to an
          affiliate of TNAI for $37.4 million.  Previously,  in the three months
          ended June 30, 2005, we recorded an impairment charge of $18.5 million
          related to our interest.

     o    Completed the sale of our 156-MW Morris power plant for  approximately
          $84.5 million. Previously, in the three months ended June 30, 2005, we
          recorded a $106.2 million impairment charge related to this facility.

     o    Purchased  approximately  $138.9  million of our First  Priority Notes
          under the terms of a tender offer.

     o    Announced a 15-year  Master  Products and Services  Agreement with GE,
          which is expected to lower operating costs in the future.  As a result
          of 9 GE LTSA  cancellations  during the  quarter,  we  recorded  $33.1
          million in charges.

     o    Signed an  agreement  with Siemens  Westinghouse  to  restructure  the
          long-term  relationship,  which we expect  will  afford us  additional
          flexibility to self-perform maintenance work in the future.

     As a result of  transactions  subsequent  to June 30, 2005, we have lowered
our total debt by approximately $1.3 billion to $17.4 billion.

     We are considering the sale of additional  assets  including the Ontelaunee
Energy Center and the  Philadelphia  Water Works Plant.  These  additional sales
could lead to additional material impairment charges or losses upon sale.

     See Note 15 of the Notes to Consolidated Condensed Financial Statements for
more information.

     The sale of assets  to  reduce  debt and  lower  annual  interest  costs is
expected to materially lower our revenues,  spark spread and gross profit (loss)
and the final mix of assets actually sold will determine the degree of impact on
operating  results.  While lowering debt,  the  accomplishment  of the strategic
initiative  program,  in and of itself,  will likely not lead to  improvement in
certain  measures  of  interest  and  principal  coverage  without   significant
improvement  in market  conditions.  The amount of  offsetting  future  interest
savings  will be a function of the  principal  amount of debt  retired,  and the
amount that we will spend to reduce debt will depend on the market price of such
debt and other factors.  The final net future earnings impact of the initiatives
is still uncertain.

     Cash  Flow  Activities  -- The  following  table  summarizes  our cash flow

     Operating  activities for the six months ended June 30, 2005, used net cash
of $239.3 million, as compared to providing $12.0 million for the same period in
2004.  In the first six  months of 2005 there was a $51.3  million  use of funds
from net changes in operating assets and liabilities  comprised of a decrease in
accounts payable and accrued  liabilities of $103.2 million,  and an increase in
net margin deposits posted to support CES contracting activity of $36.9 million.
This was  offset by  decreases  in  accounts  receivable  of $57.7  million  and
inventory of $37.6 million.

     In the first six months of 2004,  operating  cash flows  benefited from the
receipt of $100.6 million from the termination of power purchase  agreements for
two of our New Jersey power plants and $16.4 million from the restructuring of a
long-term  gas supply  contract.  We had a $51.2  million  use of funds from net
changes in  operating  assets and  liabilities,  including  an increase of $39.9
million in net margin deposits posted to support CES contracting activity.

     Investing  activities for the six months ended June 30, 2005,  consumed net
cash of $958.6  million,  as  compared  to $167.4  million in the same period of
2004. Capital expenditures,  including capitalized interest,  for the completion
of our power facilities  decreased from $795.4 million in 2004 to $539.6 million
in 2005 as there were fewer projects under construction. Investing activities in
2005 also reflected a $433.2 million increase in restricted cash, $402.5 million
of which  resulted  from the  proceeds of the  convertible  offering in June set
aside to redeem HIGH TIDES III  preferred  securities.  Investing  activities in
2004 included the receipt of $172.2  million from the disposal of the Lost Pines
power plant and certain oil and gas assets, together with $85.4 million from the
sale of a subsidiary holding power purchase agreements for two of our New Jersey
power plants and a decrease in restricted cash of $452.4 million,  offset by the
purchase of the Brazos  Valley power plant,  the  remaining  50% interest in the
Aries power plant, and the remaining 20% interest in Calpine Cogen.

     Financing  activities  for the six  months  ended June 30,  2005,  provided
$1,124.7  million,  as  compared  to $20.8  million in 2004.  We  continued  our
refinancing  program in the first six months of 2005 by raising  $260.0  million
from a preferred  security  offering by Calpine Jersey II, $155.0 million from a
preferred  security offering by Metcalf $650.0 million from the 2015 Convertible
Notes  offering,  $524.9  million from  various  project  financings  and $265.7
million from a prepaid commodity  derivative contract at our Deer Park facility.
We repaid  $236.7  million of notes  payable  and  project  financing  debt,  in
addition  to  using  $402.2  million  to  repay  or  repurchase   Senior  Notes.
Additionally, we incurred $80.3 million in financing and transaction costs.

     Working  Capital -- At June 30,  2005,  we had a negative  working  capital
balance of approximately  $555.1 million due primarily to (1) the classification
as current  liabilities  of the projected use of proceeds of $611.0  million for
bond purchase  requirements  (see Note 6 of the Notes to Consolidated  Condensed
Financial Statements for a discussion), (2) an increase of $136.5 million in net
current derivative liabilities from December 31, 2004, to June 30, 2005, and (3)
negative operating cash flow for the six months ended June 30, 2005.

     Counterparties   and  Customers  --  Our  customer  and  supplier  base  is
concentrated  within the energy  industry.  Additionally,  we have  exposure  to
trends within the energy industry, including declines in the creditworthiness of
our marketing counterparties.

     Currently,  multiple companies within the energy industry are in bankruptcy
or have below investment grade credit ratings. However, we do not currently have
any  significant  exposures to  counterparties  that are not paying on a current
basis.

     Letter of Credit  Facilities  -- At June 30, 2005 and December 31, 2004, we
had approximately $604.1 million and $596.1 million, respectively, in letters of
credit   outstanding  under  various  credit  facilities  to  support  our  risk
management  and other  operational  and  construction  activities.  Of the total
letters of credit outstanding,  $225.8 million and $233.3 million, respectively,
were issued under the cash collateralized  letter of credit facility at June 30,
2005 and December 31, 2004, respectively.

     Commodity  Margin  Deposits and Other Credit Support -- As of June 30, 2005
and December 31, 2004, to support  commodity  transactions  we had deposited net
amounts of $285.8 million and $248.9  million,  respectively,  in cash as margin
deposits  with third  parties,  and we made gas and power  prepayments  of $86.3
million, and $78.0 million,  respectively, and had letters of credit outstanding
of $127.4  million and $115.9  million,  respectively.  Since December 31, 2004,
such  amounts  have  increased  as  commodity  prices have risen.  We use margin
deposits,  prepayments  and letters of credit as credit  support  for  commodity
procurement and risk management activities.  Future cash collateral requirements
may  increase or  decrease  based on the extent of our  involvement  in standard
contracts and movements in commodity prices and also based on our credit ratings
and general perception of creditworthiness in this market.

     Unrestricted  Subsidiaries -- The information in this paragraph is required
to be provided under the terms of the Second Priority Secured Debt  Instruments.
We have designated  certain of our subsidiaries as  "unrestricted  subsidiaries"
under  the  Second  Priority  Secured  Debt   Instruments.   A  subsidiary  with
"unrestricted"  status  thereunder  generally is not required to comply with the
covenants contained therein that are applicable to "restricted subsidiaries." We
have  designated  Calpine  Gilroy 1, Inc.,  Calpine  Gilroy 2, Inc.  and Calpine
Gilroy Cogen,  L.P. as  "unrestricted  subsidiaries"  for purposes of the Second
Priority  Secured Debt  Instruments.  The  following  table sets forth  selected

     Bankruptcy-Remote   Subsidiaries  --  Pursuant  to  applicable  transaction
agreements,  we have established  certain of our entities  separate from Calpine
and its other subsidiaries.  At June 30, 2005 these entities included:  Metcalf,
Rocky Mountain  Energy  Center,  LLC,  Riverside  Energy  Center,  LLC,  Calpine
Riverside Holdings, LLC, Calpine Energy Management,  L.P., CES GP, LLC, PCF, PCF
III, CNEM Holdings, CNEM, Gilroy Energy Center, LLC, Calpine Gilroy Cogen, L.P.,
Calpine Gilroy I, Inc., Calpine King City Cogen LLC, Calpine Securities Company,
L.P.,  a parent  company of Calpine  King City Cogen LLC, and Calpine King City,
LLC, an indirect parent company of Calpine  Securities  Company,  L.P.,  Calpine
Deer Park Partner LLC, Calpine Deer Park LLC and Deer Park.

     Indenture  and  Debt  and  Lease  Covenant  Compliance  --  Certain  of our
indentures place conditions on our ability to issue indebtedness if our interest
coverage  ratio (as defined in those  indentures) is below 2:1.  Currently,  our
interest  coverage  ratio (as so  defined)  is below 2:1 and,  consequently,  we
generally  would not be allowed to issue new debt,  except for (i) certain types
of new indebtedness that refinances or replaces existing indebtedness,  and (ii)
non-recourse  debt and preferred equity interests issued by our subsidiaries for
purposes of financing  certain types of capital  expenditures,  including  plant
development,  construction and acquisition expenses. In addition, if and so long
as our  interest  coverage  ratio  is  below  2:1,  our  ability  to  invest  in
unrestricted  subsidiaries and non-subsidiary  affiliates and make certain other
types  of  restricted  payments  will  be  limited.  Moreover,  certain  of  our
indentures will prohibit any further investments in non-subsidiary affiliates if
and for so long as our  interest  coverage  ratio (as defined  therein) is below
1.75:1 and, as of June 30, 2005, such interest  coverage ratio was below 1.75:1.
We currently do not expect this limitation on our ability to make investments in
non-subsidiary affiliates to have a material impact on our business.

     Certain of our indebtedness issued in the last half of 2004 was incurred in
reliance on provisions in certain of our existing  indentures  pursuant to which
we are able to incur  indebtedness if, after giving effect to the incurrence and
the repayment of other  indebtedness  with the proceeds there from, our interest
coverage ratio (as defined in those indentures) is greater than 2:1. In order to
satisfy the interest  coverage  ratio  requirement  in  connection  with certain
securities  issued in 2004,  the proceeds of such  issuances  are required to be
used  to  repurchase  or  redeem  other  existing  indebtedness.  While  we have
completed a substantial portion of such repurchases during the fourth quarter of
2004 and the first six months of 2005, we are still in the process of completing
the required  amount of repurchases  and expect to do so as soon as practicable.
While the amount that we will be required to spend to repurchase  the applicable
remaining  principal amount of such  indebtedness  will ultimately depend on the
market prices of our outstanding  indebtedness  at the time the  indebtedness is
repurchased,  we estimate  that,  as of June 30,  2005,  as adjusted  for market
conditions and financial  covenant  calculations,  we would be required to spend
approximately $184.0 million on additional repurchases in order to fully satisfy
this requirement.  If the market price of our outstanding principal indebtedness
were to change  substantially  from current  market  prices,  the amount that we
would be  required  to spend to  repurchase  the same  principal  amount of such
indebtedness  could  be  significantly  different  from  the  amounts  currently
estimated.  The principal amount of the indebtedness  required to be repurchased
has been  classified  as Senior  Notes,  current  portion,  on our  Consolidated
Condensed  Balance  Sheet as of June 30, 2005.  Subsequent  to June 30, 2005, we
satisfied a portion of such  requirement  such that,  as of July 31,  2005,  our
estimate,  adjusted as  described  above,  is that we would be required to spend
approximately $182.0 million on additional repurchases.  See Note 7 of the Notes
to Consolidated Condensed Financial Statements.

     When we or one of our  subsidiaries  sells a  significant  asset or  issues
preferred equity, our indentures  generally require that the net proceeds of the
transaction  be used to make  capital  expenditures  or to  repurchase  or repay
certain types of indebtedness,  in each case within 365 days of the closing date
of  the  transaction.   This  general  requirement  contains  certain  customary
exceptions and, in the case of certain assets,  including the gas portion of our
oil and gas assets sold in July 2005,  that are defined as  "designated  assets"
under some of our indentures,  there are additional provisions that apply to the
sale of these assets as discussed further below. In light of these requirements,
and taking into account the amount of capital  expenditures  currently  budgeted
for the  remainder  of  2005,  and  forecasted  for  2006,  we  anticipate  that
subsequent to June 30, 2005, we will need to use a total of approximately $427.0
million of the net proceeds from the three series of preferred  equity issued by
our subsidiaries, to repurchase or repay indebtedness.  Accordingly, this amount
of long-term debt has been reclassified as Senior Notes, current portion, on our
Consolidated  Condensed  Balance Sheet as of June 30, 2005. The actual amount of
the net proceeds  that will be required to be used to  repurchase  or repay debt
will  depend  upon the actual  amount of the net  proceeds  that is used to make
capital  expenditures,  which  may be more or less  than  the  amount  currently
budgeted and/or forecasted.

     In addition, the net proceeds from the asset sales completed after June 30,
2005,  will similarly be subject to the asset sale provisions of our indentures,
and we anticipate  that, on the basis  described  above,  in connection with the
asset sales that have been completed after June 30, 2005, (including the sale of
Saltend),  an additional  $343.1 million will need to be used to make qualifying
capital  expenditures  and/or  repurchase  or repay  indebtedness.  As described
further in Note 12, however, certain bondholders filed a lawsuit concerning the
use of the proceeds from the sale of Saltend.  In connection  with that lawsuit,
the net  proceeds  from  that  sale,  after  the  redemption  of two  series  of
redeemable preferred securities,  are currently subject to an order of the Court
in that matter  requiring such proceeds to be held at or in the control of CCRC.

     As noted above,  our oil and gas assets were sold on July 7, 2005, with the
gas component of such sale constituting "designated assets" under certain of our
indentures.  These indentures  require us to make an offer to purchase our First
Priority  Notes  with  the net  proceeds  of a sale  of  designated  assets  not
otherwise  applied  in  accordance  with the other  permitted  uses  under  such
indentures.  Accordingly,  we made an offer to purchase the First Priority Notes
in June 2005.  The offer to purchase  expired on July 8, 2005, and we purchased,
with  proceeds of the sale of the gas assets,  all of the  approximately  $138.9
million in principal  amount of the First  Priority Notes tendered in connection
with the offer to  purchase.  We may use the  remaining  net  proceeds of $708.5
million  arising  from the sale of our gas assets to  acquire  new  natural  gas
and/or  geothermal energy assets permitted to be acquired under such indentures,
and a portion of such  remaining  net  proceeds  have been so applied.  However,
there  can be no  assurance  that we  would  be  successful  in  identifying  or
acquiring any additional new assets on acceptable terms or at all. If we do not,
within 180 days of receipt of the net proceeds  from the sale of our gas assets,
use all of the  remaining  net  proceeds to acquire  such new assets,  and/or to
repurchase or repay (through open market or  privately-negotiated  transactions,
tender  offers or  otherwise)  any or all of the  approximately  $646.1  million
aggregate  principal amount of First Priority Notes remaining  outstanding after
consummation  of the offer to purchase  (either of which actions we may, but are
not  required,  to take),  then we will,  to the extent that the  remaining  net
proceeds  from the sale exceed $50 million,  be required  under the terms of our
Second  Priority  Secured  Financing  Documents to make an offer to purchase our
outstanding second priority senior secured  indebtedness up to the amount of the
remaining net proceeds.

     In  connection   with  several  of  our   subsidiaries'   lease   financing
transactions (Agnews,  Geysers,  Pasadena, Broad River, RockGen and South Point)
the insurance  policies we have in place do not comply in every respect with the
insurance  requirements set forth in the financing documents.  We have requested
from the relevant  financing parties,  and are expecting to receive,  waivers of
this  noncompliance.  While  failure to have the required  insurance in place is
listed in the financing documents as an event of default,  the financing parties
may not  unreasonably  withhold  their approval of our waiver request so long as
the required  insurance  coverage is not  reasonably  available or  commercially
feasible and we deliver a report from our  insurance  consultant to that effect.
We have  delivered  the required  insurance  consultant  reports to the relevant
financing  parties and therefore  anticipate that the necessary  waivers will be
executed shortly.

     In connection with the  sale/leaseback  transaction of Agnews,  we have not
fully  complied with  covenants  pertaining to the  operations  and  maintenance
agreement, which noncompliance is technically an event of default. We are in the
process of addressing this by seeking the lessor's  approval to renew and extend
the operations and maintenance agreement for the Agnews facility.

     In  connection  with the  sale/leaseback  transaction  of Calpine  Monterey
Cogeneration,  Inc.,  we have not fully  complied with  covenants  pertaining to
amendments  to  gas  and  power  purchase  agreements,  which  noncompliance  is
technically  an event of default.  We are in the process of  addressing  this by
seeking a consent and waiver.

     Almost all of our operations  are conducted  through our  subsidiaries  and
other affiliates. As a result, we depend almost entirely upon their cash flow to
service  our  indebtedness,  including  our  ability to pay the  interest on and
principal of our Senior Notes. However, as also described in our 2004 Form 10-K,
first quarter 10-Q, and current report on Form 8-K filed with the SEC on July 1,
2005,  cash flow from  operations is currently  insufficient to meet in full our
cash,  liquidity and refinancing  obligations for the year, so we presently also
depend in part upon the success of our Strategic  Initiative program in order to
fully service our debt. In addition, financing agreements covering a substantial
portion of the indebtedness of our  subsidiaries  and other affiliates  restrict
their ability to pay dividends,  make  distributions or otherwise transfer funds
to us prior to the payment of their  obligations,  including  their  outstanding
debt, operating expenses, lease payments and reserves.

     Effective  Tax  Rate -- For the  three  months  ended  June 30,  2005,  our
effective tax rate on continuing  operations  decreased to 32.7%, as compared to
39.5% for the three months  ended June 30,  2004.  For the six months ended June
30, 2005 and 2004, the effective tax rate was 33.8% and 39.0%, respectively. The
tax rate on continuing  operations for the quarter and six months ended June 30,
2004,  have been  restated  to  reflect  the  reclassification  to  discontinued
operations  of  certain  tax  expense  related  to the  sale  of our oil and gas
reserves.   See  Note  8  of  the  Notes  to  Consolidated  Condensed  Financial
Statements.  This  effective tax rate on  continuing  operations is based on the
consideration  of  estimated  year-end  earnings  in  estimating  the  quarterly
effective rate, the effect of permanent  non-taxable  items and establishment of
valuation allowances on certain deferred tax assets.

     Off-Balance  Sheet  Commitments -- In accordance  with SFAS No. 13 and SFAS
No. 98,  "Accounting for Leases" our facility  operating  leases,  which include
certain sale/leaseback transactions, are not reflected on our balance sheet. All
lessors in these  contracts  are third  parties  that are  unrelated  to us. The
sale/leaseback transactions utilize SPEs formed by the equity investors with the
sole purpose of owning a power generation facility. 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. We have no ownership or other interest in any of these SPEs.

     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 third party debt on the books of our
unconsolidated  investments  is  not  reflected  on our  Consolidated  Condensed
Balance Sheet.  At June 30, 2005,  third party  investee debt was  approximately
$200.2 million. Of this amount, $3.1 million relates to our investment in AELLC,
for which the cost method of  accounting  was used as of December 31, 2004,  and
$45.2 million relates to our investment in Grays Ferry, which we sold subsequent
to  June  30,  2005.  Based  on our  pro  rata  ownership  share  of each of the
investments,  our  share  would be  approximately  $84.8  million.  This  amount
includes  our  share  for AELLC of $1.0  million  and for  Grays  Ferry of $22.6
million.  All such debt is  non-recourse  to us. The  increase in investee  debt
between  periods is primarily due to borrowings  for the  Valladolid  III Energy
Center  currently  under  construction.  The  July  2005  sale  of  Grays  Ferry
eliminates  our share of that  facility's  debt,  representing  a  reduction  of
approximately $22.6 million of our unconsolidated,  non-recourse project debt as
of June 30, 2005. See Note 6 of the Notes to  Consolidated  Condensed  Financial
Statements for additional information on our equity and cost method investments.

     We own a 32.3% interest in AELLC. AELLC owns the 136-MW Androscoggin Energy
Center  located in Maine.  On November  3, 2004,  a jury  verdict  was  rendered
against AELLC in a breach of contract  dispute with IP. See Note 12 of the Notes
to Consolidated  Condensed Financial  Statements for more information about this
legal proceeding. We recorded our $11.6 million share of the award amount in the
third  quarter of 2004. On November 26, 2004,  AELLC filed a voluntary  petition
for relief  under  Chapter 11 of the U.S.  Bankruptcy  Code.  As a result of the
bankruptcy,  we lost  significant  influence and control of the project and have
adopted the cost method of  accounting  for our  investment  in AELLC.  Also, in
December  2004,  we  determined  that our  investment  in AELLC was impaired and
recorded a $5.0 million impairment  reserve. On April 12, 2005, AELLC sold three
fixed-price gas contracts to Merrill Lynch Commodities  Canada,  ULC, and used a
portion of the proceeds to pay down its remaining  construction debt. As of June
30, 2005, the facility had  third-party  debt  outstanding of $3.1 million.  See
Note 12 of the  Notes to  Consolidated  Condensed  Financial  Statements  for an
update on this investment.

     Credit  Considerations  -- On May 9, 2005,  Standard & Poor's  lowered  its
corporate  credit rating on Calpine  Corporation to single B- from single B. The
outlook  remains  negative.  In addition,  the ratings on Calpine's debt and the
ratings on the debt of its subsidiaries  were also lowered by one notch,  with a
few exceptions.

     On May 12, 2005, Moody's Investor Service lowered its senior implied issuer
rating on Calpine  Corporation to B3 from B2. The outlook remains  negative.  In
addition,  the  ratings  on  Calpine's  debt and the  ratings on the debt of its
subsidiaries were also lowered by two notches, with a few exceptions.

     On May 25,  2005,  following  the  announcement  of  Calpine  Corporation's
strategic  program  to  accelerate  the $3  billion  debt  reduction  target  to
year-end,  Fitch Ratings  placed the credit  ratings of Calpine  Corporation  on
rating watch evolving, meaning Fitch may lower, maintain, or raise their ratings
on the Company's debt securities in the near-term.

     Credit  rating  downgrades  have had a negative  impact on our liquidity by
reducing  attractive  financing  opportunities  and  increasing  the  amount  of
collateral  required  by  trading  counterparties.   Any  future  credit  rating
downgrades could have similar effects on our liquidity.

     Capital  Spending  -- See  Note 5 of the  Notes to  Consolidated  Condensed
Financial  Statements  for a  discussion  of our  development  and  construction
projects at June 30, 2005

Performance Metrics

     In understanding our business,  we believe that certain non-GAAP  operating
performance metrics are particularly important. These are described below:

     o    Total  deliveries  of power.  We both  generate  power that we sell to
          third  parties  and  purchase  power for sale to third  parties in HBO
          transactions.  The former sales are recorded as electricity  and steam
          revenue and the latter sales are recorded as sales of purchased  power
          for  hedging  and  optimization.  The  volumes in MWh for each are key
          indicators of our respective levels of generation and HBO activity and
          the sum of the two, our total deliveries of power, is relevant because
          there are occasions  where we can either generate or purchase power to
          fulfill contractual sales commitments. Prospectively beginning October
          1, 2003, in accordance with EITF 03-11,  "Reporting Realized Gains and
          Losses on Derivative  Instruments That Are Subject to SFAS No. 133 and
          Not `Held for  Trading  Purposes'  As Defined in EITF Issue No.  02-3:
          "Issues  Involved in  Accounting  for  Derivative  Contracts  Held for
          Trading  Purposes and  Contracts  Involved in Energy  Trading and Risk
          Management  Activities,"  certain sales of purchased power for hedging
          and  optimization are shown net of purchased power expense for hedging
          and  optimization  in  our   consolidated   statement  of  operations.
          Accordingly,  we have also  netted HBO volumes on the same basis as of
          October 1, 2003, in the table below.

     o    Average availability and average baseload 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 baseload  capacity  factor,  sometimes  called  operating rate, is
          calculated by dividing (a) total megawatt hours generated by our power
          plants  (excluding  peakers)  by the  product of  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  baseload
          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
          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.

     o    Average all-in  realized  electric price  expressed in dollars per MWh
          generated.   Our  risk  management  and  optimization  activities  are
          integral to our power  generation  business  and  directly  impact our
          total realized revenues from generation. Accordingly, we calculate the
          all-in  realized  electric  price per MWh  generated  by dividing  (a)
          adjusted  electricity  and  steam  revenue,  which  includes  capacity
          revenues, energy revenues, thermal revenues and the spread on sales of
          purchased power for hedging,  balancing, and optimization activity, by
          (b) total generated MWh in the period.

     o    Average cost of natural gas expressed in dollars per millions of Btu's
          of fuel  consumed.  Our risk  management and  optimization  activities
          related to fuel  procurement  directly  impact our total fuel expense.
          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  fuel expense
          which  includes the cost of fuel  consumed by our plants  (adding back
          cost of  inter-company  gas pipeline  charges,  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 fuel expense from
          (b)  adjusted E&S revenue and  dividing  the  difference  by (c) total
          generated MWh in the period.

     o    Average plant  operating  expense per normalized MWh. To assess trends
          in electric power POX per MWh, we normalize the results from period to
          period by assuming a constant 70% total  company-wide  capacity factor
          (including both base load and peaker capacity) in deriving  normalized
          MWh. By normalizing the cost per MWh with a constant  capacity factor,
          we can better analyze trends and the results of our program to realize
          economies of scale,  cost reductions and  efficiencies at our electric
          generating  plants.  For  comparison  purposes we also include POX per
          actual MWh.

     The table below  presents,  the  operating  performance  metrics  discussed
above.


                                                                          Three Months Ended June 30,    Six Months Ended June 30,

California Power Market

     The  volatility  in the  California  power  market  from  mid-2000  through
mid-2001 has produced significant  unanticipated  results. The unresolved issues
arising  in that  market,  where 41 of our 95 power  plants are  located,  could
adversely  affect  our  performance.  See Note 14 of the  Notes to  Consolidated
Condensed Financial Statements for a further discussion.

Financial Market Risks

     As we are 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.

     The change in fair value of outstanding  commodity  derivative  instruments
from January 1, 2005 through June 30, 2005, is summarized in the table below (in
thousands):

     Derivative  commodity  instruments included in the table are those included
in Note 9 of the Notes to 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 fair
value of electricity  derivative commodity instruments after a 10% adverse price
change  includes the effect of  increased  power  prices  versus our  derivative
forward commitments.  Conversely,  the fair value of the natural gas derivatives
after a 10% adverse price change reflects a general decline in gas prices versus
our derivative forward commitments.  Derivative commodity instruments offset the
price risk  exposure of our physical  assets.  None of the  offsetting  physical
positions are included in the table above.

     Price changes were calculated by assuming an  across-the-board  10% 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 10% change in prices,  the fair value of our derivative  portfolio  would
typically  change by more than 10% for earlier  forward months and less than 10%
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 increased by 81%
from  December  31, 2004,  to June 30, 2005,  and the total volume of open power
derivative  positions  increased by 158% 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,  "Accounting  for Derivative  Instruments and
Hedging  Activities,"  the change since the last balance sheet date in the total
value of the derivatives  (both assets and  liabilities) is reflected  either in
OCI, net of tax, or in the  statement of operations as an item (gain or loss) of
current earnings. As of June 30, 2005, a significant component 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 three and six months ended June 30, 2005,  have reflected
this.  See  Notes  8 and 9 of the  Notes  to  Consolidated  Condensed  Financial
Statements for additional information on derivative activity.

     Interest  Rate  Swaps  -- From  time to time,  we use  interest  rate  swap
agreements  to mitigate our exposure to interest  rate  fluctuations  associated
with  certain of our debt  instruments  and to adjust the mix between  fixed and
floating  rate debt in our capital  structure to desired  levels.  We do not use
interest rate swap agreements for speculative or trading purposes. The following
tables  summarize  the fair market  values of our  existing  interest  rate swap
agreements as of June 30, 2005 (dollars in thousands):

     Currency Exposure -- We own subsidiary entities in several countries. These
entities  generally have functional  currencies other than the U.S.  dollar.  In
most cases, the functional currency is consistent with the local currency of the
host country where the particular  entity is located.  In certain cases,  we and
our foreign subsidiary entities hold monetary assets and/or liabilities that are
not  denominated  in the  functional  currencies  referred  to  above.  In  such
instances,   we  apply  the  provisions  of  SFAS  No.  52,  "Foreign   Currency
Translation,"  ("SFAS No. 52") to account for the monthly  re-measurement  gains
and losses of these assets and  liabilities  into the functional  currencies for
each entity.  In some cases we can reduce our potential  exposures to net income
by designating liabilities denominated in non-functional currencies as hedges of
our net  investment  in a foreign  subsidiary  or by  entering  into  derivative
instruments  and  designating  them in hedging  relationships  against a foreign
exchange exposure.  Based on our unhedged exposures at June 30, 2005, the impact
to our pre-tax  earnings  that would be expected  after a 10% adverse  change in

$Cdn-$US........................................              (119,120)
Other...........................................                (2,598)

     In  prior  periods,   we  reported   significant   unhedged  positions  and
corresponding  foreign currency transaction gains and losses due to our exposure
to changes in the GBP-$US exchange rate. As a result of the sale of Saltend (see
Notes 8 and 15 of the Notes to Consolidated  Condensed Financial  Statements for
more information),  effectively all of our GBP-$US exposure has been eliminated.
We expect that currency  movements will continue  create  volatility  within our
pre-tax  earnings in future  periods,  but such  volatility will not result from
movements in the GBP-$US exchange rate.

     Significant changes in exchange rates will also impact our CTA balance when
translating  the  financial  statements  of our  foreign  operations  from their
respective functional  currencies into our reporting currency,  the U.S. dollar.
An example of the impact that  significant  exchange rate  movements can have on
our Balance Sheet position  occurred in 2004.  During 2004, our CTA increased by
approximately  $62 million  primarily  due to a  strengthening  of the  Canadian
dollar and GBP against the U.S. dollar by approximately 7% each.

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

     The  $Cdn-$US  gain for the  three  months  ended  June 30,  2005,  was due
primarily to a  strengthening  of the U.S.  dollar  against the Canadian  dollar
during the second quarter of 2005. In September 2004, we sold  substantially all
of our oil and gas assets in Canada,  which significantly  reduced the degree to
which we could designate our $Cdn-denominated  liabilities as hedges against our
investment in Canadian dollar denominated subsidiaries.  As a result, we are now
considerably  more exposed to fluctuations  in the $Cdn-$US  exchange rate as we
hold  several  significant  $Cdn-denominated  liabilities  that can no longer be
hedged under SFAS No. 52. When the U.S.  dollar  strengthened  during the second
quarter of 2005, significant  remeasurement gains were triggered on these loans.
This  gain was  partially  offset  by  remeasurement  losses  recognized  on the
translation of the interest  receivable  associated with our large  intercompany
loan that has been deemed a permanent investment under SFAS No. 52.

     The $Cdn-$US  loss for the three  months ended June 30, 2004,  was moderate
despite  the fact that the U.S.  dollar  strengthened  considerably  against the
Canadian  dollar during the second  quarter of 2004. The primary reason for this
was because the majority of our existing  $Cdn-$US  exposures  were  effectively
designated as hedges of our net investment in Canadian  dollar  subsidiaries  at
June 30, 2004. As a result,  remeasurement  gains that otherwise would have been
recognized  within our  Consolidated  Condensed  Statements of  Operations  were
recorded  within CTA in  accordance  with SFAS No. 52. The primary  exception to
this was the remeasurement of the interest receivable  associated with our large
intercompany loan that has been deemed a permanent investment under SFAS No. 52.
Because the interest is physically  settled on a recurring  basis, all gains and
losses  associated with this  remeasurement are recorded within our Consolidated
Condensed  Statements  of Operations as opposed to within CTA. The $Cdn-$US loss
of $4.0 million for the three months ended June 30, 2004,  was due  primarily to
such remeasurement losses as a result of the strengthening of the U.S. dollar.

     During the three months ended June 30, 2005, the Euro weakened  against the
GBP, triggering re-measurement gains associated with our Euro-denominated 8 3/8%
Senior Notes Due 2008. Conversely,  during the three months ended June 30, 2004,
the Euro  strengthened  slightly  against the GBP,  resulting in  re-measurement
losses associated with these Senior Notes.

     The primary  driver  behind our loss of $1.9  million  from other  currency
fluctuations  for the  three  months  ended  June 30,  2005,  was a  significant
strengthening  of the U.S.  dollar  against the Euro,  and its impact on certain
U.S. dollar-denominated  intercompany trade payables owed by our TTS subsidiary.
For the three months  ended June 30,  2004,  our loss of $0.5 million from other
currency  fluctuations  was primarily the result of a  strengthening  of the GBP
against the Canadian  dollar,  which  increased the  $Cdn-equivalent  of several
GBP-denominated  intercompany  interest payables held by one of our subsidiaries
in Canada.

Six Months Ended June 30, 2005, Compared to Six Months Ended June 30, 2004:

     The major  components of our foreign  currency  transaction  gains of $25.5

and 2004, respectively, are as follows (amounts in millions):

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

     The $Cdn-$US gain for the six months ended June 30, 2005, was due primarily
to a  strengthening  of the U.S.  dollar against the Canadian  dollar during the
first half of 2005. In September 2004, we sold  substantially all of our oil and
gas assets in Canada,  which significantly  reduced the degree to which we could
designate our  $Cdn-denominated  liabilities as hedges against our investment in
Canadian dollar denominated  subsidiaries.  As a result, we are now considerably
more exposed to  fluctuations  in the $Cdn-$US  exchange rate as we hold several
significant $Cdn-denominated liabilities that can no longer be hedged under SFAS
No.  52.  When the U.S.  dollar  strengthened  during  the  first  half of 2005,
significant  remeasurement  gains were  triggered on these loans.  This gain was
partially  offset by remeasurement  losses  recognized on the translation of the
interest  receivable  associated with our large  intercompany loan that has been
deemed a permanent investment under SFAS No. 52.

     The  $Cdn-$US  loss for the six months  ended June 30,  2004,  was moderate
despite  the fact that the U.S.  dollar  strengthened  considerably  against the
Canadian  dollar during the first half of 2004.  The primary reason for this was

intercompany loan that has been deemed a permanent investment under SFAS No. 52.
Because the interest is physically  settled on a recurring  basis, all gains and
losses  associated with this  remeasurement are recorded within our Consolidated
Condensed  Statements  of Operations as opposed to within CTA. The $Cdn-$US loss
of $4.7  million for the six months ended June 30,  2004,  was due  primarily to
such  remeasurement  losses as a result of the  strengthening of the U.S. dollar
during the first half of 2004.

     During the six months ended June 30, 2005 and 2004, respectively,  the Euro
weakened against the GBP,  triggering  re-measurement  gains associated with our
Euro-denominated 8 3/8% Senior Notes Due 2008.

     The primary  driver behind our losses of $3.0 million and $1.1 million from
other  currency  fluctuations  for the six months  ended June 30, 2005 and 2004,
respectively,  was a  combination  of a  significant  strengthening  of the U.S.
dollar  against  the Euro,  and its  impact on certain  U.S.  dollar-denominated
intercompany   trade   payables  owed  by  our  TTS  subsidiary  as  well  as  a
strengthening  of the GBP against  the  Canadian  dollar,  which  increased  the
$Cdn-equivalent of several  GBP-denominated  intercompany interest payables held
by one of our subsidiaries in Canada.

     Available-for-Sale  Debt  Securities  --  Through  June  30,  2005,  we had
repurchased $115.0 million par value of HIGH TIDES III preferred securities.  At
June 30,  2005,  the  repurchased  HIGH  TIDES  III  preferred  securities  were
classified  as  available-for-sale  and  recorded at fair market  value in Other
current  assets.  See  Notes 4 and 15 of the  Notes  to  Consolidated  Condensed
Financial Statements for further information.

     Debt Financing -- Because of the significant  capital  requirements  within
our industry,  debt  financing is often needed to fund our growth.  Certain debt
instruments may affect us adversely because of changes in market conditions.  We
have used two  primary  forms of debt  which are  subject  to market  risk:  (1)
Variable  rate  construction/project   financing  and  (2)  other  variable-rate
instruments.  Significant  LIBOR  increases  could have a negative impact on our
future interest expense.

     Our variable-rate  construction/project  financing is primarily through the
CalGen  floating  rate  notes,  institutional  term loans and  revolving  credit
facility.  Borrowings  under our $200 million CalGen  revolving credit agreement
are used  primarily  for  letters of credit in support of gas  purchases,  power
contracts and  transmission,  and include funding for the construction  costs of
CalGen  power  plants (of which  only the  Pastoria  Energy  Center was still in
active construction at June 30, 2005). Other  variable-rate  instruments consist
primarily of our revolving credit and term loan  facilities,  which are used for
general  corporate   purposes.   Both  our  variable-rate   construction/project
financing  and  other  variable-rate  instruments  are  indexed  to base  rates,
generally LIBOR, as shown below.

     The following  table  summarizes by maturity  date our  variable-rate  debt
exposed to interest  rate risk as of June 30, 2005.  All fair market  values are
shown net of applicable premium or discount, if any (dollars in thousands):

     Summary of Dilution  Potential of Our Contingent  Convertible  Notes:  2023
Convertible  Notes,  2015 Convertible  Notes and 2014  Convertible  Notes -- The
table below assumes  normal  conversion  for the 2014  Convertible  Notes,  2015
Convertible  Notes and 2023  Convertible  Notes in which the principal amount is
paid in cash,  and the  excess up to the  conversion  value is paid in shares of
Calpine  common stock.  The table shows only the  potential  impact of our three
contingent  convertible  notes  issuances  and does not  include  the  potential
dilutive  effect of the now fully redeemed HIGH TIDES III preferred  securities,
the remaining 4%  Convertible  Senior Notes due 2006 or employee  stock options.
Additionally,  we are still assessing the potential impact of the SFAS No. 128-R
exposure draft on our contingent convertible  securities.  See Notes 2 and 11 of
the Notes to Consolidated Condensed Financial Statements for more information.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

     See "Financial Market Risks" in Item 2.


Item 4. Controls and Procedures.

Disclosure Controls and Procedures

     We maintain  disclosure controls and procedures that are designed to ensure
that  information  we are required to disclose in reports that we file or submit
under the Securities Exchange Act of 1934 is recorded, processed, summarized and
reported within the time periods specified in SEC rules and forms, and that such
information is accumulated and  communicated  to our  management,  including our
Chief Executive Officer and Chief Financial  Officer,  as appropriate,  to allow
timely decisions regarding required disclosure.

     As of December 31, 2004,  management identified a material weakness related
to our tax accounting  processes,  procedures and controls that was discussed in
Item 9A of the Company's 2004 Form 10-K.  During the first two quarters of 2005,
we have taken the steps necessary to improve our internal  controls  relating to
the  preparation  and review of interim and annual income tax  provisions and to
remediate this material  weakness.  While significant  progress has been made in
the  remediation  of these  controls,  the controls  have not yet operated for a
sufficient  period of time to allow us to complete the  required  testing and to
conclude that they are designed and operating effectively.

     Our senior  management,  including  our Chief  Executive  Officer and Chief
Financial  Officer,  evaluated the effectiveness of our disclosure  controls and
procedures as of the end of the period covered by this quarterly  report.  Based
on the status of the remediation of the material  weakness,  our Chief Executive
Officer and our Chief Financial Officer  concluded that our disclosure  controls
and procedures are not effective. We continue to perform additional analysis and
post-closing  procedures to ensure our  consolidated  financial  statements  are
prepared in  accordance  with GAAP.  Accordingly,  management  believes that the
financial  statements  included in this report  fairly  present in all  material
respects our financial  condition,  results of operations and cash flows for the
periods presented.  The certificates required by this item are filed as Exhibits
31.1, 31.2 and 32.1 to this Form 10-Q.

Status of Remediation of the Material Weakness

     During the first two quarters of 2005, we have taken the steps necessary to
improve our internal  controls relating to the preparation and review of interim
and annual income tax  provisions,  including the  accounting for current income
taxes  payable and  deferred  income tax assets and  liabilities.  We have hired
additional  resources  and have  engaged  third party tax experts to improve the
effectiveness  of the controls  over  management's  review of the details of the
income tax  calculations.  We have also  improved the process of  preparing  and
reviewing  the   workpapers   supporting  our  tax  related   calculations   and
conclusions.

     We will continue to do the following:

     o    Complete the  implementation  of the CorpTax computer  application and
          enhance  other  financial  applications  to  automate  more of the tax
          analysis and  provision  processes and continue to improve the clarity
          of supporting documentation and reports, and

     o    Add additional  resources in the tax department as well as provide tax
          accounting training for key personnel.

     We continue to monitor the effectiveness of the tax controls and procedures
and will make any additional changes that management deems appropriate.

Changes in Internal Control Over Financial Reporting

     We  continuously  seek to improve the efficiency and  effectiveness  of our
internal  controls.  This results in  refinements  to processes  throughout  the
Company.  During  the first two  quarters  of 2005,  there  were no  significant
changes in our internal control over financial reporting, other than the changes
related to the tax  accounting  processes,  procedures  and  controls  discussed
above, that materially affected,  or are reasonably likely to materially affect,
our internal control over financial reporting.
