                      CALPINE CORPORATION AND SUBSIDIARIES

              NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS
                                 March 31, 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 in the United States of America, Canada, and the United Kingdom. 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,  gas fields,  gathering systems and gas pipelines,  geothermal steam
fields and  geothermal  power  generation  facilities  in the  United  States of
America.  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.  In the
United  Kingdom,  the Company owns and operates a gas-fired  power  cogeneration
facility.  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.
Gas produced,  and not physically  delivered to the Company's generating plants,
is  sold  to  third  parties.   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
operations and maintenance ("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 7 for more information.

     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,  primary beneficiary determination for the Company's
investments  in  variable  interest  entities  ("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.

     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 March
31, 2005 and December 31, 2004, $254.0 million and $191.0 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 March 31,
2005 and 2004,  $115.6 million and $192.3 million of the Company's cash and cash
equivalents  was held in bank  accounts  outside the United  States for the same
periods, respectively.

     Accounting for Commodity  Contracts -- Commodity contracts are evaluated to
determine  whether the contract is: (1) accounted for as a lease,  (2) accounted
for  as a  derivative  or  (3)  accounted  for  as  an  executory  contract  and
additionally whether the financial statement presentation is gross or net.

     Leases  --  Commodity  contracts  are  evaluated  for lease  accounting  in
accordance  with SFAS No. 13,  "Accounting  for  Leases,"  ("SFAS  No.  13") and
Emerging  Issues Task Force  ("EITF") Issue No. 01-08,  "Determining  Whether an
Arrangement  Contains a Lease," ("EITF Issue No.  01-08").  EITF Issue No. 01-08
clarifies the  requirements  of  identifying  whether an  arrangement  should be
accounted  for as a lease at its  inception.  The  guidance in the  consensus is
designed to broaden the scope of arrangements, such as power purchase agreements
("PPA"),  accounted for as leases. EITF Issue No. 01-08 requires both parties to
an arrangement to determine  whether a service  contract or similar  arrangement
is, or includes, a lease within the scope of SFAS No. 13. The consensus is being
applied  prospectively  to  arrangements  agreed to,  modified,  or  acquired in
business combinations on or after July 1, 2003. Prior to adopting EITF Issue No.
01-08, the Company had accounted for certain contractual  arrangements as leases
under existing industry practices,  and the adoption of EITF Issue No. 01-08 did
not materially change the Company's accounting for leases. Under the guidance of
SFAS No. 13,  operating  leases with minimum  lease rentals which vary over time
must be levelized over the term of the contract. The Company currently levelizes
these contracts on a straight-line  basis.  Prepaid lease expense (the excess of
lease  payments  made over the  levelized  expense  recognized)  totaled  $433.7
million  and  $426.7   million  at  March  31,  2005  and   December  31,  2004,
respectively,  which is recorded in the Company's Consolidated Condensed Balance
Sheets  within  "Other  current  assets" and as "Prepaid  Lease,  net of current
portion." For income statement presentation purposes, income from PPAs accounted
for as leases is  classified  within  "Electricity  and  steam  revenue"  in the
Company's Consolidated Condensed Statements of Operations.

     Effective  Tax Rate -- For the  three  months  ended  March 31,  2005,  the
effective  rate  decreased  to 33% as compared to 41% for the three months ended
March 31, 2004.  The tax rate on  continuing  operations  for the quarter  ended
March  31,  2004,  has  been  restated  to  reflect  the   reclassification   to
discontinued  operations of certain tax expense (benefit) related to the sale of
oil  and  gas  reserves.  See  Note 7 of the  Notes  to  Consolidated  Condensed
Financial Statements.  This effective rate variance is due to 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,"
("SFAS  No.  150")  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.

     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 months ended March 31, 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"  ("SFAS  No.  123") and  supersedes
Accounting Principles Board ("APB") Opinion No. 25, "Accounting for Stock Issued
to Employees" ("APB Opinion No. 25"), 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,"  ("SFAS
No.  148") 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"  ("SFAS No.
128") 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
Senior Notes and 2014  Convertible  Notes contain  provisions that would require
share  settlement in the event of conversion  under  certain  limited  events of
default, including bankruptcy.  Additionally,  the 2023 Convertible Senior Notes
include a  provision  allowing  the  Company to meet a put with  either  cash or
shares of stock.  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 2023 Convertible  Senior 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" ("SFAS No. 151").  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, this Statement 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," ("SFAS No. 153"). This standard eliminates the exception in APB Opinion
No. 29,  "Accounting  for Nonmonetary  Transactions"  ("APB Opinion No. 29") 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"  ("SFAS No. 66"),  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.

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" ("EITF Issue No.
03-13"). 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 considered 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  (see Note 7 for more  information).  The final  consensus  did not
change  the   Company's   original   conclusions   reached  under  the  existing
discontinued operations guidance in SFAS No. 144, "Accounting for the Impairment

     On September 30, 2004, the Company  repurchased par value of $115.0 million
HIGH TIDES III for cash of $111.6  million.  Due to the  deconsolidation  of the
Trusts upon the adoption of FIN 46 as of December 31, 2003, and the terms of the
underlying  debentures,  the  repurchased  HIGH  TIDES  III  could not be offset
against  the  convertible  subordinated  debentures  and  are  accounted  for as
available-for-sale securities and recorded in the Consolidated Condensed Balance
Sheets  within "Other  assets" at fair market value at March 31, 2005,  with the
difference from their repurchase price recorded in OCI (in thousands):

- ----------
<FN>
(1)  There are a total of eight projects in active  construction.  This includes
     the seven  projects  that are  recorded  in CIP in the table  above and one
     project that is recorded in unconsolidated investments.
</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   --  The  seven   projects  in  active
construction are projected to come on line from May 2005 to November 2007. These
projects will bring on line approximately  2,878 MW of base load capacity (3,210
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 March 31, 2005,  the total  projected  costs to complete  these
projects is $843.7 million and the estimated  funding  requirements  to complete
these projects,  net of expected project  financing  proceeds,  is approximately
$48.3 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  will  bring  on  line
approximately  1,769 MW of base load capacity (2,035 MW with peaking  capacity).
The Company expects to finance the remaining  $340.8 million  projected costs to
complete these projects.

     Projects in Advanced  Development -- There are eleven  projects in advanced
development.  These projects will bring on line  approximately  5,072 MW of base
load capacity (6,150 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.  The estimated  cost to complete the eleven  projects in
advanced  development is approximately $3.1 billion.  The Company's current plan
is to finance these project costs as PPAs are arranged.

     Suspended   Development   Projects  --  Due  to  current   electric  market
conditions,  we have ceased  capitalization of additional  development costs and
interest  expense on six 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.  These projects would bring on line  approximately  2,956 MW of base load
capacity (3,409 MW with peaking capacity).  The estimated cost to complete these
projects is approximately $1.8 billion.

     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, oil and gas and geothermal  resource and
facilities development, as well as software developed for internal use.

     Unassigned Equipment -- As of March 31, 2005, the Company had made progress
payments on four turbines and other  equipment with an aggregate  carrying value
of $66.2 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,"  ("SFAS No. 34") 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  oil  and  gas  properties   under   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 March 31, 2005
and 2004, the total amount of interest capitalized was $70.4 million, and $108.5
million,  including $10.7 million and $18.5 million,  respectively,  of interest
incurred on funds borrowed for specific  construction projects and $59.7 million
and $90.0 million, respectively, of interest incurred on general corporate funds
used for the advanced stages of development and 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  months  ended
March 31, 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 quarter ended March 31, 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.

5.   Unconsolidated Investments

     The Company's  unconsolidated  investments  are integral to its operations.
The  Company's  joint  venture  investments  were  evaluated  under  FASB-issued
Interpretation  No.  46  "Consolidation  of  Variable  Interest  Entities  -  An
Interpretation  of ARB 51" ("FIN 46") to determine which, if any,  entities were
VIEs.  Based on this  evaluation,  the Company  determined that the Acadia Power
Partners,   LLC,   Valladolid  III  Energy  Center,   Grays  Ferry  Cogeneration
Partnership, Whitby Cogeneration Limited Partnership and Androscoggin Energy LLC
were VIEs, in which the Company held a significant  variable interest.  However,
all of the entities except for Acadia Power Partners,  LLC 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  Power  Partners,  LLC, 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 the Androscoggin Energy Center as discussed below.

     Acadia Power Partners,  LLC ("Acadia PP") is the owner of a  1,210-megawatt
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 March 31, 2005, is limited to the book value of its  investment of
approximately  $216.5  million,  plus any loss  that may  accrue  from a tolling
agreement between Acadia and Calpine Energy Services, L.P. ("CES").

     Valladolid  III  Energy  Center  is the  owner of a  525-megawatt,  natural
gas-fired  energy center currently under  construction at Valladolid,  Mexico in
the Yucatan Peninsula. The facility will deliver electricity to Comision Federal
de Electricidad ("CFE") under a 25-year power sales agreement.  The project is a
joint venture  between the Company,  Mitsui & Co.,  Ltd.,  ("Mitsui")  and Chubu
Electric  ("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 March 31, 2005, is limited
to the book value of its investment of approximately $82.2 million.

     Grays  Ferry  Cogeneration  Partnership  ("Grays  Ferry") is the owner of a
175-megawatt gas-fired  cogeneration facility,  Grays Ferry Power Plant, 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,  Cogeneration  Corporation of
America, Inc. ("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.  The Company's  maximum  potential  exposure to loss at March 31,
2005,  is limited to the book value of its  investment  of  approximately  $49.4
million.

     Whitby  Cogeneration  Limited  Partnership  ("Whitby")  is the  owner  of a
50-megawatt gas-fired  cogeneration  facility,  Whitby Cogeneration,  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  Energy Inc.  ("Westcoast")  in September
2001,  which included the Whitby joint venture  project.  The Company's  maximum
potential  exposure to loss at March 31,  2005,  is limited to the book value of
its investment of approximately $38.4 million.

     Androscoggin Energy LLC ("AELLC") is the owner of a 136-megawatt  gas-fired
cogeneration  facility,  Androscoggin  Energy Center,  located in Maine and is a
joint venture  between the Company,  and affiliates of Wisvest  Corporation  and
International Paper Company ("IP"). The Company's  involvement in this VIE began
with its  acquisition  of the  independent  power  producer,  SkyGen  Energy LLC
("SkyGen")  in October  2000.  The AELLC  project was part of the  portfolio  of
assets owned by SkyGen.  The facility had construction debt of $59.6 million and
$60.3  million  outstanding  as of  March  31,  2005,  and  December  31,  2004,
respectively.  The debt is non- recourse to Calpine Corporation.  On November 3,
2004, a jury verdict was rendered  against AELLC in a breach of contract dispute
with IP.  See Note 11 for more  information  about  the  legal  proceeding.  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. See Note 14 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 Calpine
     Power, LP ("CPLP")  through a loan from CPLP to the Company's  entity which
     holds the investment interest in Whitby.

(2)  Excludes certain Notes Receivable.

     On  September  2,  2004,  the  Company  completed  the  sale of its  equity
investment in the Calpine  Natural Gas Trust  ("CNGT").  In accordance with SFAS
No.  144 the  Company's  25 percent  equity  method  investment  in the CNGT was
considered  part of the  larger  disposal  group  and  therefore  evaluated  and
accounted  for  as a  discontinued  operation.  Accordingly,  the  Company  made
reclassifications  to current and prior period  financial  statements to reflect
the sale or designation as "held for sale" of the CNGT investment balance and to
separately classify the income from the unconsolidated investment as well as the
gain on sale of the investment from operating  results of continuing  operations
to discontinued operations.  The tables below for distributions from investments
and related party  transactions  with  unconsolidated  investments  include CNGT
through the date of sale,  September 2, 2004. See Note 7 for more information on
the sale of the Canadian natural gas reserves and petroleum assets.

     The third party debt on the books of the unconsolidated  investments is not
reflected on the Company's  balance  sheet.  At March 31, 2005, and December 31,
2004,  third party  investee debt was  approximately  $220.3  million and $130.8
million,  respectively.  Of these  amounts,  $59.6  million  and $60.3  million,
respectively,  relates to the Company's  investment in AELLC, for which the cost
method of  accounting  was used as of December 31, 2004.  Based on the Company's
pro rata ownership share of each of the  investments,  the Company's share would
be  approximately  $86.2 million and $45.6 million for the  respective  periods.
These amounts  include the Company's  share for AELLC of $19.2 million and $19.5
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 March 31, 2005 and  December  31,  2004,
reflected in the accompanying  Consolidated  Condensed  Balance Sheets,  and the
related party  transactions for the three months ended March 31, 2005, and 2004,
reflected in the accompanying  Consolidated  Condensed  Statements of Operations

6.   Debt

     On January 28, 2005,  the  Company's  indirect  subsidiary  Metcalf  Energy
Center, LLC ("Metcalf") obtained a $100.0 million,  non-recourse credit facility
for the Metcalf  Energy Center in San Jose,  CA. Loans extended to Metcalf under
the  facility  will  fund  the  balance  of  construction   activities  for  the
602-megawatt,  natural  gas-fired power plant. The project finance facility will
mature in July  2008.  As of March  31,  2005,  the  Company  had $15.5  million
outstanding under this credit facility.

     On January 31, 2005, the Company's  indirect  subsidiary,  Calpine European
Funding  (Jersey) Limited  ("Calpine  Jersey II"),  received funding on a $260.0
million  offering of  Redeemable  Preferred  Shares,  due on July 30, 2005.  The
shares were offered in a private placement in the United States under Regulation
D under the Securities Act of 1933 and outside of the United States  pursuant to
Regulation S under the Securities Act of 1933. The Redeemable  Preferred  Shares
priced at U.S.  LIBOR plus 850 basis  points,  were  offered at 99% of par.  The
proceeds  from the  offering of the shares must be used in  accordance  with the
provisions of the Company's existing bond indentures. See "Indenture Compliance"
below for a further discussion.

     On March 1, 2005, our indirect subsidiary, Calpine Steamboat Holdings, LLC,
closed on a $503.0  million  non-recourse  project  finance  facility  that will
provide $466.5 million to complete the construction of the Mankato Energy Center
("Mankato")  in Blue Earth  County,  Minnesota,  and the Freeport  Energy Center
("Freeport")  in Freeport,  Texas.  The remaining  $36.5 million of the facility
provides a letter of credit for Mankato that is required to serve as  collateral
available  to  Northern  States  Power  Company  if  Mankato  does  not meet its
obligations  under the PPA.  The project  finance  facility  will  initially  be
structured as a  construction  loan,  converting to a term loan upon  commercial
operations of the plants,  and will mature in December  2011.  The facility will
initially be priced at LIBOR plus 1.75%.  As of March 31, 2005,  the Company had
$48.0  million  and  $54.7  million   outstanding   for  Mankato  and  Freeport,
respectively, under this project finance facility.

     During the three months ended March 31, 2005, the Company repurchased $31.8
million in principal  amount of its  outstanding 8 1/2% Senior Notes Due 2011 in
exchange  for $23.0  million in cash plus  accrued  interest.  The Company  also
repurchased  $48.7 million in principal  amount of its outstanding 8 5/8% Senior
Notes Due 2010 in exchange for $35.0 million in cash plus accrued interest.  The
Company  recorded a pre-tax  gain on these  transactions  in the amount of $21.8
million  after  write-offs  of  unamortized  deferred  financing  costs  and the
unamortized discounts.

     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
financing,  convertible  senior  notes,  and senior notes and term loans,  as of
March 31, 2005, are as follows (in thousands):

          April through December 2005......  $    1,199,063
          2006.............................       1,122,490

          Thereafter.......................      10,302,845

          Total debt.......................      18,372,946
          (Discount) / Premium.............        (228,988)
                                             --------------
            Total..........................  $   18,143,958
                                             ==============

     The total  current  debt  obligation  as of March 31,  2005,  was  $1,510.7
million,  which  consisted of $1,199.1  million of April  through  December 2005
repayments  or  maturities  and $311.6  million  of the  $1,122.5  million  2006
repayments or maturities.

     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  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.  As of March 31, 2005,  the
Company's  interest  coverage ratio (as so defined) has fallen below 1.75:1 and,
until the ratio is greater than 1.75:1, certain of the Company's indentures will
prohibit any further investments in non-subsidiary affiliates.

     Certain of the Company's  indebtedness  issued in the last half of 2004 was
permitted under the Company's indentures on the basis that the proceeds would be
used to repurchase or redeem existing indebtedness.  While the Company completed
a portion of such  repurchases  during the fourth  quarter of 2004 and the first
quarter of 2005,  the Company is still in the process of completing the required
amount of  repurchases.  While the  amount of  indebtedness  that must  still be
repurchased  will  ultimately  depend  on the  market  price  of  the  Company's
outstanding  indebtedness at the time the indebtedness is repurchased,  based on
current market conditions,  the Company estimates that, as of March 31, 2005, as
adjusted for market conditions and financial covenant calculations,  the Company
would  be  required  to spend  approximately  $294.0  million  in order to fully
satisfy  this  requirement.  This amount has been  classified  as Senior  Notes,
current  portion,  on  the  Company's   Consolidated  Condensed  Balance  Sheet.
Subsequent  to March 31,  2005,  the  Company  has  satisfied  a portion of such
requirement. See Note 14.

     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  subsidiary  indebtedness,  in each case
within  365  days of the  closing  date of the  transaction.  In  light  of this
requirement,  and  taking  into  account  the  amount  of  capital  expenditures
currently  budgeted for 2005, the Company  anticipates  that subsequent to March
31, 2005,  it will need to use  approximately  $250.0 of the net proceeds of the
$360.0  million  Two-Year  Redeemable  Preferred  Shares  issued by its  Calpine
(Jersey)  Limited  ("Calpine  Jersey I")  subsidiary  on October 26,  2004,  and
approximately  $180.0  million  of  the  net  proceeds  of  the  $260.0  million
Redeemable Preferred Shares issued by its Calpine Jersey II on January 31, 2005,
to repurchase  or repay certain  subsidiary  indebtedness.  Accordingly,  $430.0
million  of  long-term  debt has been  reclassified  as  Senior  Notes,  current
portion,  on the Company's  Consolidated  Condensed  Balance  Sheet.  The actual
amount of the net  proceeds  that will be required to be used to  repurchase  or
repay  subsidiary  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.

     As noted  above,  the  Company  has  significant  debt  maturities  or bond
purchase requirements in 2005 as well as significant debt maturities in 2006 and
beyond.  During  the  first  quarter  of 2005,  the  Company's  cash  flow  from
operations  used $114.6  million and at March 31, 2005, the Company had negative
working  capital of $299.1  million.  In addition,  as noted in Note 11, certain
bond holders have raised issues  concerning  the use of proceeds from certain of
the planned or recently executed transactions.

     In addition,  satisfying all  obligations  under the Company's  outstanding
indebtedness,  and funding anticipated capital  expenditures and working capital
requirements  for the next  twelve  months  presents  the Company  with  several
challenges over the near term as the Company's cash requirements  (including the
Company's  refinancing   obligations)  are  expected  to  exceed  the  Company's
unrestricted cash on hand and cash from operations. Accordingly, the Company has
in  place  a  liquidity-enhancing  program  which  includes  possible  sales  or
monetizations of certain of the Company's  assets,  and whether the Company will
have  sufficient  liquidity  will  depend on the  success  of that  program.  No
assurance  can be given that the Company's  liquidity-enhancing  program will be
successful.  Even if the Company's  liquidity-enhancing  program is  successful,
there can be no  assurance  that the  Company  will  continue  its  construction
program without  suspending  further  construction or development work on one or
more projects and possibly incurring substantial  impairment losses as a result.
For further  discussion of this see the risk factors in our 2004 Form 10-K.  See
below for progress achieved in the Company's  liquidity program during the three
months ended March 31,  2005.  On March 31, 2005,  the  Company's  cash and cash
equivalents  on hand totaled $0.8 billion (see Note 2), and the current  portion
of restricted cash totaled approximately $0.5 billion.

     Calpine has  guaranteed the payment of a portion of the rents due under the
lease of the  Greenleaf  generating  facilities  in  California.  This  lease is
between  an owner  trustee  acting  on behalf of Union  Bank of  California,  as
lessor, and a Calpine subsidiary,  Calpine Greenleaf,  Inc., as lessee.  Calpine
does not currently meet the  requirements of a financial  covenant  contained in
the guarantee agreement.  The lessor has waived this non-compliance  through May
15, 2005, and Calpine is currently in discussions  with the lessor to modify the
lease,  Calpine's  guarantee  thereof,  and  other  related  documents  so as to
eliminate  the  covenant in question.  In the event the lessor's  waiver were to
expire  prior to  completion  of this  amendment,  the lessor could at that time
elect to  accelerate  the  payment of  certain  amounts  owing  under the lease,
totaling  approximately  $16.0 million. In the event the lessor were to elect to
require  Calpine to make this payment,  the lessor's  remedy under the guarantee
and the lease would be limited to taking steps to collect  damages from Calpine;
the lessor would not be entitled to terminate or exercise  other  remedies under
the Greenleaf lease.

     In  connection   with  several  of  our   subsidiaries'   lease   financing
transactions (Agnews,  Geysers,  Greenleaf,  Pasadena,  Rumford/Tiverton,  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 the Company's  waiver request so long as the required  insurance  coverage is
not reasonably  available or commercially  feasible and we deliver a report 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.

     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  indebtedness
(collectively,  the "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.

7.   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.

Oil and Gas Production and Marketing

     On September 1, 2004,  the Company  along 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 billion cubic feet equivalent  ("Bcfe") of proved
gas reserves,  producing  approximately  16.3 million net cubic feet  equivalent
("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 the CNGT.  In  accordance  with SFAS No. 144 the  Company's  25% equity
method  investment in the 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.

Electric Generation and Marketing

     On January 15,  2004,  the  Company  completed  the sale of its  50-percent
undivided  interest  in the 545  megawatt  Lost Pines 1 Power  Project to GenTex
Power  Corporation,  an affiliate of the Lower Colorado River Authority  (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 megawatts 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."

Summary

     The Company made  reclassifications  to current and prior period  financial
statements  to reflect the sale of these oil and gas and power plant  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  significant  components of the Company's  income
from  discontinued  operations  for the three months  ended March 31, 2004,  (in
thousands). The Company had no corresponding income from discontinued operations
for the three  months  ended March 31,  2005,  and no assets held for sale as of
March 31, 20005.

     Of the  Company's  net  derivative  liabilities,  $257.7  million and $50.4
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 records the
derivative assets of PCF in its balance sheet.

     On March 31, 2005,  Deer Park Energy  Center,  Limited  Partnership  ("Deer
Park"), an indirect, wholly owned subsidiary of Calpine, entered into agreements
to sell power to and buy gas from Merrill Lynch Commodities,  Inc. ("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  a cash  payment  of  $195.8  million,  net of $17.3  million  in
transaction   costs,  and  expects  to  receive   additional  cash  payments  of
approximately  $70 million as additional  power  transactions  are executed with
discounts  to  prevailing  market  prices.  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.  The
discounted pricing under the agreements  resulted in the recognition of a $213.1
million  derivative  liability.  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.

     At any  point in time,  it is highly  unlikely  that  total net  derivative
liabilities and liabilities will equal  accumulated Other  Comprehensive  Income
("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 March 31, 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"  ("EITF
Issue No.  03-11") -- 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 $303.8 million and $370.5  million  against sales in the
quarters ended March 31, 2005, and March 31, 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
March 31, 2005.

     As of March 31, 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 $192.0
million would be  reclassified  from AOCI into earnings during the twelve months
ended  March 31,  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

9.   Comprehensive Income (Loss)

     Comprehensive  income is the total of net  income  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 three months ended March 31, 2005 and 2004 in the  Company's
AOCI  balance  and the  components  of the  Company's  comprehensive  income (in

10.  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).


                                                                               Periods Ended March 31,

     The Company incurred losses before  discontinued  operations and cumulative
effect of a change in accounting principle for the quarters ended March 31, 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 11.4 million and 72.6 million  shares of the  Company's  common stock
were not included in the  computation of diluted shares  outstanding  during the
quarters  ended March 31, 2005 and 2004,  respectively,  because such  inclusion
would be antidilutive.

     For the quarters ended March 31, 2005 and 2004,  approximately  0.1 million
and  23.8  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 March 31, 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.

     For the quarters  ended March 31, 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
Senior Notes issued in November 2003,  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 $6.50 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 2023  Convertible  Senior Notes and included (if dilutive) in
the diluted EPS calculation is  approximately  97.5 million  shares;  the actual
number of potential shares depends on the closing stock price at conversion.

     Similarly,  for the quarter ended March 31, 2005, 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  outstanding  2014
Convertible  Notes as the inclusion of such shares would have been  antidilutive
because of the Company's net loss. However, in future reporting periods when the
Company has income before  discontinued  operations and  cumulative  effect of a
change in accounting  principle and the closing stock price is above $3.85,  the
maximum  potential  shares issuable under the conversion  provisions of the 2014
Convertible  Notes and included in the diluted EPS calculation is  approximately
191.2  million  shares;  the actual  number of potential  shares  depends on the
closing stock price at conversion.

     For the quarter  ended March 31,  2005,  318,787  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.

     In  conjunction  with the 2014  Convertible  Notes  offering,  the  Company
entered into a ten-year  Share  Lending  Agreement  with Deutsche Bank AG London
("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.
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 of 1933  ("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,  plaintiffs  filed  their  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. The
TAC defines the potential  class to include all purchasers of the Notes pursuant
to the  registration  statement and  prospectuses on or before January 27, 2003.
The Court has not yet certified the class.  The class  certification  hearing is
set for May 10, 2005.

     The Court has set a November 7, 2005 trial date.  Fact discovery will close
on July 1,  2005.  Lead  plaintiff  has  moved for a 120 day  extension  of fact
discovery and other deadlines, which necessarily would affect the trial date. 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,  Cartwright,  Curtis,
John Wilson,  Kenneth Derr, George Stathakis,  CSFB, Banc of America Securities,
Deutsche  Bank  Securities,  and  Goldman,  Sachs & Co.  Plaintiff is the Hawaii
Structural Ironworkers Pension Trust 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 discovery  cut off date or trial date in this action.  The next
scheduled court hearing will be a case management conference on July 5, 2005, at
which time the court may set a discovery  deadline  and 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 Employee Retirement Income Security Act ("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 Calpine  Corporation  Retirement Savings Plan (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
fourth claim was  dismissed  with leave to amend.  We expect the second  amended
consolidated  complaint to be filed on May 9, 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,
International Paper Company ("IP") filed a complaint against Androscoggin Energy
LLC ("AELLC") alleging that AELLC breached certain  contractual  representations
and warranties  arising out of an Amended Energy Services  Agreement  ("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 Section  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.

     Panda Energy International,  Inc., et al. v. Calpine Corporation, et al. On
November 5, 2003, Panda Energy International,  Inc. and certain related parties,
including PLC II, LLC,  (collectively  "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  Energy  Center  ("Oneta"),  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  and past due. The note is  collateralized  by Panda's
carried  interest  in the income  generated  from  Oneta,  which  achieved  full
commercial  operations in June 2003. Calpine filed a counterclaim  against Panda
Energy International, Inc. (and PLC II, LLC) 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.

     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 Calpine Energy Services, L.P., ("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.

     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 California Department of Water Resources. Millar was removed to federal
court, but has now been remanded back to State Superior Court for handling.  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, Nevada Power Company ("NPC") and Sierra Pacific
Power  Company  ("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.  ("Reliant")  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).  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 (a) Calpine  would take service under the TSA if NPC proceeds to
execute a PPA with MEC based on MEC's  winning bid in the Request for  Proposals
that NPC conducted in 2003;  (b) if NPC did not execute a PPA with MEC,  Calpine
would  terminate  the TSA and any  payment by Calpine  would be limited to a pro
rata  allocation of certain costs incurred by NPC in connection  with the second
phase of the  project  (approximately  $4.5  million in total to date) among the
three customers to be served.

     On November  18,  2004,  FERC  issued a decision in Docket No.  EL04-90-000
which 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 of the November 18,
2004 decision,  alleging that FERC had erred in holding that a determination  of
damages  for breach of either  Calpine or Reliant  was  premature  and that both
Calpine and Reliant had breached their respective TSAs.  Calpine filed an answer
on January 4, 2005  requesting  that FERC deny NPC's request for  rehearing.  On
April 20, 2005,  FERC issued its Order  Denying  Request for  Rehearing.  In the
Order, the Commission  denies Nevada Power's request for rehearing  stating that
it finds that the dispute  between  Calpine and Nevada Power 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,  that NPC  should
exercise its duty to mitigate its damages, if any, and that NPC should not incur
any additional costs or expenses in reliance upon the TSA for Calpine's account.
Calpine  introduced  the November 22, 2004 Letter into  evidence in  proceedings
before the Public Utilities  Commission of Nevada ("PUCN") regarding NPC's third
amendment to its integrated  resource plan  ("Resource  Plan").  In the Resource
Plan, NPC sought  approval to proceed with the  construction of the second phase
of the  Centennial  Project  (the  transmission  project  intended  to serve the
Calpine and Reliant  TSAs) (the "HAM  Line").  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 of
the  December  28,  2004 order.  On  February 9, 2005,  the PUCN issued an order
denying Calpine's 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 (discussed below) or any possible
action by NPC before FERC  regarding  Calpine's  notice that it will not perform
its obligations under the Calpine TSA.

     Calpine had previously  provided security to NPC for Calpine's share of the
HAM Line costs,  in the form of a surety bond issued by Fireman's Fund Insurance
Company ("FFIC"). 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.

     FFIC's  complaint sought an order declaring that (a) FFIC has no obligation
to make payment under the bond; and (b) if the court were to determine that FFIC
has an obligation to make payment, then (i) Calpine has an obligation to replace
it with funds  equal to the  amount of NPC's  demand  against  the bond and (ii)
Calpine is obligated to indemnify and hold FFIC harmless for all loss, costs and
fees  incurred as a result of the issuance of the bond.  Calpine filed an answer
denying the  allegations  of the complaint and asserting  affirmative  defenses,
including that it has fully performed its  obligations  under the TSA and surety
bond. 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.  On  November 4, 2004,  the case was  removed to Federal  District
Court.  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  Natural  Gas  Partnership  ("Calpine  Canada")  filed  a
complaint in the Alberta Court of Queens Branch alleging that Enron Canada Corp.
("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. Discovery is currently in progress, and 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 Darrell Jones of National Energy Systems Company  ("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 Power Partners, LLC ("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 power purchase  agreements ("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  executed  a tolling  agreement  to extend  the time for
binding  arbitration  (up to and  including  until  July 23,  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,  and that  Acadia PP could be liable to CES for an
amount up to $3.1 million.

     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  have  agreed  to  discuss  possible
resolution alternatives 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 has 30 days to file an objection
and request a hearing before a Administrative  Law Judge.  Otherwise,  the DOL's
findings become final.  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 Power Partners ("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 believes
that  Cutrale's  position is not  supported  by the  language of the contract in
place between Auburndale PP and Cutrale and that it will prevail in arbitration.
Nevertheless,  to preserve its positive relationship with Cutrale, Auburndale PP
will continue 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 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 the
owner  of  the  Saltend   Energy  Centre  (the  "Saltend   Facility"),   Saltend
Cogeneration  Company  Limited.  The Bonds have been guaranteed by Calpine.  The
Application alleges that Calpine and the named subsidiaries violated the Harbert
Fund's rights under  certain Nova Scotia and Canadian  laws in  connection  with
certain  financing  transactions  completed by subsidiaries of CCR that are also
named in the  Application  and may violate the Harbert  Fund's rights under such
laws in connection with the proposed sale of the Saltend  Facility.  The Harbert
Fund seeks relief under such laws  including  interim and  permanent  injunctive
relief  freezing at, or tracing and  returning  to, CCR,  assets  including  the
proceeds of the financing  transactions  and proceeds of any sale of the Saltend
Facility. The return date on the Application is August 31 and September 1, 2005.
Calpine  believes that it and its  subsidiaries  named in the  Application  have
strong  defenses under Nova Scotia law to the requests for final relief advanced
by the Harbert Fund and that the Harbert  Fund,  on a balance of  probabilities,
will not likely prevail in its application  before the Nova Scotia Supreme Court
for final relief.  Calpine and the subsidiaries  named in the Application intend
to defend vigorously against the allegations.

     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.

12.  Operating Segments

     The  Company is first and  foremost  an  electric  generating  company.  In
pursuing this business strategy,  it has been the Company's objective to produce
a portion of its fuel consumption requirements from its own natural gas reserves
("equity gas"). The Company's oil and gas production and marketing  activity has
reached the  quantitative  criteria to be considered a reportable  segment under
SFAS No. 131. The  Company's  segments are  therefore  electric  generation  and
marketing;  oil and gas  production  and  marketing;  and  corporate  and  other
activities.   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.  Oil and gas  production  includes the
ownership and operation of gas fields,  gathering  systems and gas pipelines for
internal   gas   consumption,   third  party  sales  and   hedging,   balancing,
optimization, and trading activity transacted on behalf of the Company's oil and
gas operations.  Corporate  activities and other consists primarily of financing
transactions,  activities of the Company's  parts and services  businesses,  and
general  and  administrative   costs.  Certain  costs  related  to  company-wide
functions are allocated to each segment, such as interest expense, distributions
on HIGH TIDES prior to October 1, 2003, and interest income, which are allocated
based on a ratio of segment assets to total assets.

     The Company  evaluates  performance  based upon several criteria  including
profits  before tax. The accounting  policies of the operating  segments are the
same as those  described  in Note 2. The  financial  results  for the  Company's
operating  segments have been prepared on a basis  consistent with the manner in
which the Company's management  internally  disaggregates  financial information
for the purposes of assisting in making internal operating decisions.

     Due to the  integrated  nature  of the  business  segments,  estimates  and
judgments have been made in allocating  certain  revenue and expense items,  and
reclassifications  have been made to 2004  periods  to  present  the  allocation
consistently.

     Intersegment  revenues  primarily relate to the use of internally  procured
gas by the  Company's  power  plants.  These  intersegment  revenues  have  been
included in Segment  profit (loss) before  provision for income taxes in the oil
and gas  production  and  marketing  reporting  segment  and  eliminated  in the
corporate and other reporting segment.

13.  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  California  Independent  System  Operator
("CAISO") and the California Power Exchange ("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,  The  Williams  Companies,  Inc.  ("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 megawatt  hour 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
Qualifying  Facilities  ("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 who  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 "reliability must
run" contracts  ("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. To date,  FERC has not  established a
Section 206  proceeding.  The outcome of this  litigation  and the impact on the
Company's business cannot be determined at the present time.

14.  Subsequent Events

     On April 12, 2005, the Company's unconsolidated investment AELLC sold three
fixed price gas contracts  for gross cash proceeds of $116.0  million to Merrill
Lynch Commodities Canada, ULC. On April 13, 2005, a portion of the proceeds from
the sale were used to pay down the remaining  construction  debt  outstanding of
$58.1 million as well as costs  associated  with the  termination of an interest
rate swap agreement.

     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.  The ratings
for the following debt issues remained unchanged: the BBB- SPUR rating on Gilroy
Energy Center bonds,  the BB- rating on the Rocky Mountain Energy Center and the
Riverside Energy Center loans, the CCC+ rating on the third lien CalGen debt and
the BBB rating on the Power Contract  Financing LLC bonds.  Such downgrade could
increase the cost of future borrowings and other costs of doing business.

     During the second  quarter of 2005  (through May 9, 2005),  the Company has
repurchased in open market  transactions  $116.3 million of the principal amount
of its outstanding debt as listed below:

         10 1/2% Senior Notes Due 2006                      $3,485,000
         7 5/8% Senior Notes Due 2006                       $1,335,000
         8 3/4% Senior Notes Due 2007                       $3,000,000
         7 3/4% Senior Notes Due 2009                      $35,000,000
         8 5/8% Senior Notes Due 2010                      $37,468,000
         8 1/2% Senior Notes Due 2011                      $36,000,000

     The  securities,  which  were  trading at a  discount  to par  value,  were
repurchased in exchange for approximately $69.6 million in cash.

     On May 10, 2005, Metcalf,  the Company's indirect  subsidiary,  commenced a
$155 million offering of 5.5-Year Redeemable  Preferred Shares.  Concurrent with
the issuance of the Preferred  Shares,  Metcalf intends to refinance,  through a
five-year,  $100 Million Senior Term Loan, an existing $100 million non-recourse
construction  credit facility.  The proceeds from the offering of the Redeemable
Preferred  Shares  will  be  used  as  permitted  by  Calpine's   existing  bond
indentures.  Proceeds  from the offering of the Senior Term Loan will be used to
refinance all outstanding  indebtedness under the existing  construction  credit
facility,  to complete  construction of the Metcalf power plant, to pay fees and
expenses related to the transaction, and as permitted by Calpine's existing bond
indentures.

Item 2. Management's Discussion and Analysis ("MD&A") of Financial Condition and
        Results of Operations.

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.

</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 Calpine  Energy  Services,  L.P.  ("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
Staff  Accounting  Bulletin ("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 U.K.
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 own and  produce  natural  gas  and to a  lesser  extent  oil,  which  we use
primarily to lower our costs of power  production and provide a natural hedge of
fuel costs for a portion of our electric power plants, but also to generate some
revenue through sales to third parties.  We protect and enhance the value of our
electric and gas 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 near-term 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.

     Electricity and steam revenue  increased as average megawatts in operations
of our  consolidated  plants  increased  by 20.7% to 26,368 MW while  generation
increased  by 6.2%.  In addition,  average  realized  electric  price before the
effects of hedging,  balancing and optimization,  increased from $59.19 / MWh in
2004 to $62.78 / 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. Because we increased utilization of our generating assets
during the three months  ending March 31, 2005, as compared to the quarter ended
March 31, 2004, our revenues from the resale of transmission capacity declined.

     Sales of  purchased  power for hedging and  optimization  decreased  in the
three months ended March 31, 2005,  due  primarily to lower  volumes  which were
partially offset by higher prices, as compared to the same period in 2004.

     Oil and gas sales are net of internal  consumption,  which is eliminated in
consolidation.  Internal  consumption  decreased  from $53.1 in 2004 to $43.0 in
2005   primarily  as  a  result  of  lower   production.   Before   intercompany
eliminations,  oil and gas sales  decreased from $67.2 in 2004 to $53.8 in 2005,
primarily  as a result of a 25%  decrease  in  production,  which was  partially
offset by a 10% average increase in gas prices.

     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"  ("EITF  Issue  No.  02-3")  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 mark-to-market activities revenue in the three months ended
March 31,  2005,  as  compared to the same  period in 2004 is due  primarily  to
increases   in  liquidity   reserves  on  our   mark-to-market   positions   and
mark-to-market  losses  on our  Calpine  Generating  Company,  LLC's  ("CalGen")
option.

     Plant operating  expense and  transmission  purchase expense both increased
due to additional  power plants  achieving  commercial  operation  subsequent to
March 31, 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  decrease during the
three months  ended March 31,  2005,  as compared to the same period in 2004 due
primarily to a reduction in volumes as compared to the same period in 2004.

     Purchased  gas expense for hedging and  optimization  increased  during the

     Cost of oil and gas  burned  by power  plants  increased  during  the three
months  ended March 31,  2005,  as compared to the same period in 2004 due to an
increase in gas  consumption as we increased our megawatt  production and higher
prices for gas excluding the effects of hedging, balancing and optimization.

     Recognized  (gain)  loss on gas hedges  decreased  during the three  months
ended March 31, 2005, as compared to the same period in 2004 due to  unfavorable
gas price movements against our gas financial instrument hedging positions.

Depreciation, depletion and amortization expense.............  $     143.2  $     129.4  $     (13.8)    (10.7)%


     Depreciation, depletion and amortization expense increased primarily due to
the additional power facilities in consolidated  operations  subsequent to March
31, 2004.

Operating lease expense......................................  $      24.8  $      27.8  $       3.0      10.8%


     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........................................  $      38.2  $      26.4  $     (11.8)    (44.7)%


     Other cost of revenue  increased  during the three  months  ended March 31,
2005,  as compared to the same period in 2004 due  primarily to $17.3 of expense
for  transaction  costs incurred on the closing of an agreement to sell power to
and  buy gas from Merrill Lynch  Commodities,  Inc. ("MLCI").  See Note 8 of the

     The increase in income was  primarily  due to unplanned  outages in 2004 at
our Grays Ferry power  project  combined with the fact that (a) in March 2004 we
purchased  the  remaining  50%  interest in the Aries Power Plant (at which time
this plant was  consolidated)  and (b)  effective  December  2004,  we ceased to
recognize our share of the operating  results of Androscoggin  Energy Center LLC
("AELLC") as we determined  that our  investment  was impaired  following a jury
verdict against AELLC in a breach of contract dispute with  International  Paper
Company ("IP").  See Notes 5 and 11 of the Notes to the Consolidated  Financial
Statements for further information.

     Equipment  cancellation  and impairment  costs  decreased  during the three
months ended March 31, 2005,  as compared to the same period in 2004 as a result
of a $2.3 termination fee recorded in 2004 in connection with the termination of

Research and development expense.............................  $       7.0  $       3.8  $      (3.2)    (84.2)%


     Research and development  expense  increased  during the three months ended
March  31,  2005,  as  compared  to the same  period  in 2004  primarily  due to
increased personnel expenses related to new research and development programs at
our Power Systems Mfg., LLC ("PSM") subsidiary.

     Sales, general and administrative expense increased during the three months
ended March 31, 2005,  primarily due to an increase in Sarbanes-Oxley  (SOX) and
tax consulting and legal fees.

Interest expense.............................................  $     348.9  $     248.5  $    (100.4)    (40.4)%


     Interest  expense  increased as a result of higher  average debt  balances,
higher average  interest  rates and lower  capitalization  of interest  expense.
Interest capitalized  decreased from $108.5 for the three months ended March 31,
2004, to $70.4 for the three months ended March 31, 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.  Additionally,  during the three  months  ended March 31,  2005,  (i)
interest  expense  related to our senior notes and term loans increased by $9.6;
(ii) interest expense related to our CalGen  subsidiary  increased $13.3;  (iii)
interest  expense  related to our  construction/project  financing  increased by
$16.7; (iv) interest expense related to our Calpine Construction Finance Company
L.P ("CCFC I") subsidiary increased by $2.2; and (v) interest expense related to
preferred interests increased by $13.6 primarily due to the October 2004 closing
of  the  $360  million  offering  associated  with  the  Saltend  Energy  Centre
("Saltend"),  and  the  $260  offering  on  January  31,  2005  by our  indirect
subsidiary, Calpine European Funding (Jersey) Limited ("Calpine Jersey II").

     Interest  (income)  increased during the three months ended March 31, 2005,
due primarily to higher interest rates compared to the same period in 2004.

Minority interest expense....................................  $      10.6  $       8.4  $      (2.2)    (26.2)%


     Minority interest expense increased during the three months ended March 31,
2005,  as compared to the same  period in 2004  primarily  due to an increase of
$2.0 of minority interest expense  associated with the Calpine Power Income Fund
("CPIF's") 70% interest in Calpine Power Limited Partnership (CPLP").

     Other expense was $4.0 for the three months ended March 31, 2005,  compared
to other income of $18.4 for the three months ended March 31, 2004. The variance
includes a $4.8  decrease  in the  foreign  currency  transaction  gain  between
periods. In addition, in 2004 we recorded a gain on the sale of a variety of oil
and gas  properties  to the  Calpine  Natural  Gas Trust  ("CNGT") of $6.2 and a
favorable warranty settlement in the amount of $5.1.

Benefit for income taxes.....................................  $     (84.8) $     (73.2) $      11.6      15.8%


     During the three months ended March 31, 2005, our tax benefit  increased by
$11.6 as compared to the three  months  ended March 31, 2004 as our pre-tax loss
increased in 2005. The effective tax rate decreased to 33.4% in 2005 compared to
40.6%  in  the  same  period  in  2004  primarily  due to  additional  valuation
allowances against deferred tax assets in 2005, thus lowering the tax benefit.

     During  2004,  our  discontinued   operations   activities  were  comprised
primarily of a gain,  net of tax of $22.9,  from the sale of our 50% interest in
the Lost Pines 1 Power Project and operating activities associated with the sale
of our Canadian natural gas reserves and petroleum  assets,  and the sale of our
oil and gas  reserves  in the  Colorado  Piceance  Basin and New Mexico San Juan
Basin.

Net loss.....................................................  $    (168.7) $     (71.2) $     (97.5)   (136.9)%


     For the three  months  ended March 31,  2005,  we reported  revenue of $2.2
billion,  representing an increase of 9% over the same period in the prior year,
and a net loss per share of $0.38, or a net loss of $168.7 million,  compared to
a net  loss per  share of  $0.17,  or a net loss of $71.2  million  for the same
quarter in the prior year.

     For the three months ended March 31,  2005,  average  capacity in operation
increased by 21% to 26,368 megawatts.  We generated  approximately  22.4 million
megawatt-hours, which equated to a baseload capacity factor of 44%, and realized
an average  spark  spread of $24.10 per  megawatt-hour.  For the same  period in
2004,  we generated  21.1 million  megawatt-hours,  which  equated to a capacity
factor of 50%, and realized an average spark spread of $20.65 per megawatt-hour.

     Gross profit  increased by $28.5 million,  or 25%, to $140.6 million in the
three  months  ended  March 31,  2005,  over the same  period in the prior year.
Despite improvements in market fundamentals, total spark spread, which increased
by $104.2  million,  or 24%, in the first  quarter of 2005  compared to the same
period in 2004,  did not  increase  commensurately  with the  increases in plant
operating  expense,  transmission  purchase  expense,  depreciation and interest
expense associated with new power plants coming on-line. In the first quarter of
2005 gross profit was reduced by  transaction  fees of $17.3 million  associated
with  prepaid  commodity  transactions  at  Deer  Park  Energy  Center,  Limited
Partnership ("Deer Park"), our indirect, wholly owned subsidiary.

     During the three  months  ended  March 31,  2005,  financial  results  were
affected by a $100.5 million  increase in interest  expense,  as compared to the
same period in 2004.  This occurred as a result of higher debt balances,  higher
average  interest  rates and lower  capitalization  of  interest  expense as new
plants entered commercial operation and capitalization of interest was suspended
on three  partially  constructed  power  plants.  However,  we  recorded a $21.8
million gain from the repurchase of debt.

     Other  expense was $4.0  million for the three months ended March 31, 2005,
compared to other  income of $18.4  million for the three months ended March 31,
2004. The difference  included a $4.7 million  decrease in the foreign  currency
transaction gain between periods. In addition, in 2004 we recorded a gain on the
sale of a variety of oil and gas  properties  to the CNGT of $6.2  million and a
favorable warranty settlement in the amount of $5.1 million.

     Income from discontinued operations,  net of tax for the three months ended
March 31,  2004 was as a result  of the gain  from the sale of the Lost  Pines 1
Power  Project and  represents  the  operations  of the  Company's  Canadian and
certain U.S. oil and gas assets that were sold during the third quarter of 2004.
There were no assets held for sale as of March 31, 2005.

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 or prepay 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.  We also reinvest our cash from  operations  into our business
development and  construction  program or use it to reduce debt,  rather than to
pay cash dividends.

     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 in the past. In particular,  our senior
working  capital  facility and term loan financings and the majority of our debt
securities  offered and sold in this period have been  secured by certain of our
assets and equity  interests.  We have also  provided  security  to support  our
prepaid commodity financing transactions. The terms of financing available to us
now  and in the  future  may  not be  attractive  to us and  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  presents us with several  challenges  over the near
term as our  cash  requirements  (including  our  refinancing  obligations)  are
expected  to exceed  our  unrestricted  cash on hand and cash  from  operations.
Accordingly,  we have in  place a  liquidity-enhancing  program  which  includes
possible sales or  monetizations  of certain of our assets,  and whether we will
have  sufficient  liquidity  will  depend on the  success  of that  program.  No
assurance can be given that our liquidity-enhancing  program will be successful.
Even if our liquidity-enhancing program is successful, there can be no assurance
that we will  continue  our  construction  program  without  suspending  further
construction or development work on one or more projects and possibly  incurring
substantial  impairment losses as a result.  For further  discussion of this see
the risk factors in our 2004 Form 10-K.  See below for progress  achieved in our
liquidity  program  during the three months  ended March 31, 2005.  On March 31,
2005, our cash and cash  equivalents on hand totaled $0.8 billion (see Note 2 of
the Notes to  Consolidated  Condensed  Financial  Statements),  and the  current
portion of restricted cash totaled approximately $0.5 billion.

     Liquidity Transactions in the Three Months Ended March 31, 2005:

     On January 28, 2005, our indirect  subsidiary  Metcalf  Energy Center,  LLC
("Metcalf")  obtained a $100.0  million,  non-recourse  credit  facility for the
Metcalf  Energy  Center in San Jose,  CA.  Loans  extended to Metcalf  under the
facility  will fund  remaining  construction  activities  for the  602-megawatt,
natural  gas-fired power plant. The project finance facility will mature in July
2008.

     On January 31, 2005, our subsidiary, Calpine Jersey, II, completed a $260.0
million  offering  of  Redeemable  Preferred  Shares  due  July  30,  2005.  The
Redeemable  Preferred Shares,  priced at U.S. LIBOR plus 850 basis points,  were
offered at 99% of par. The proceeds from the offering of the shares were used in
accordance with the provisions of our existing bond indentures.

     On March 1, 2005, our indirect subsidiary, Calpine Steamboat Holdings, LLC,
closed on a $503.0  million  non-recourse  project  finance  facility  that will
provide $466.5 million to complete the construction of the Mankato Energy Center
("Mankato")  in Blue Earth  County,  Minnesota,  and the Freeport  Energy Center
("Freeport")  in Freeport,  Texas.  The remaining  $36.5 million of the facility
provides a letter of credit for Mankato that is required to serve as  collateral
available  to  Northern  States  Power  Company  if  Mankato  does  not meet its
obligations  under the power purchase  agreement  ("PPA").  The project  finance
facility will  initially be structured as a construction  loan,  converting to a
term loan upon commercial  operations of the plant,  and will mature in December
2011. The facility will initially be priced at LIBOR plus 1.75%.

     On March 31,  2005,  Deer Park,  our  indirect,  wholly  owned  subsidiary,
entered  into an  agreement  to sell power to and buy gas from  MLCI.  To assure
performance under the agreements,  Deer Park granted MLCI a collateral  interest
in the Deer Park  Energy  Center.  The  agreements  cover 650 MW of Deer  Park's
capacity  and  deliveries  under the  agreement  will begin on April 1, 2005 and
continue through December 31, 2010. Under the terms of the agreements, Deer Park
will sell power to MLCI at a discount to  prevailing  market  prices at the time
the agreements were executed.  In exchange for the discounted pricing, Deer Park
received a cash payment of approximately $195.8 million, net of $17.3 million in
transaction   costs,  and  expects  to  receive   additional  cash  payments  of
approximately  $70 million as  additional  power  transactions  are  executed at
discounts to prevailing market prices.

     Debt Repurchases and Redemptions:

     During the three months ended March 31, 2005, we repurchased, at a discount
in  open  market  transactions,   $31.8  million  in  principal  amount  of  our
outstanding  8 1/2% Senior Notes Due 2011 in exchange for $23.0  million in cash
plus accrued interest.  We also repurchased $48.7 million in principal amount of
our  outstanding  8 5/8% Senior Notes Due 2010 in exchange for $35.0  million in
cash plus accrued interest.  After the write-off of deferred financing costs and
unamortized discounts on the notes, we recorded a pre-tax gain on the repurchase
of debt totaling approximately $21.8 million.

     During the second  quarter  of 2005  (through  May 9,  2005),  Calpine  has
repurchased in open market  transactions  $116.3 million of the principal amount
of its outstanding debt as listed below:

         10 1/2% Senior Notes Due 2006                      $3,485,000
         7 5/8% Senior Notes Due 2006                       $1,335,000
         8 3/4% Senior Notes Due 2007                       $3,000,000
         7 3/4% Senior Notes Due 2009                      $35,000,000
         8 5/8% Senior Notes Due 2010                      $37,468,000
         8 1/2% Senior Notes Due 2011                      $36,000,000

     The  securities,  which  were  trading at a  discount  to par  value,  were
repurchased in exchange for approximately $69.6 million in cash.

     In  2004,  all of our  outstanding  HIGH  TIDES I and  HIGH  TIDES  II were
redeemed.  At March 31, 2005,  $517.5 million of principal  amount of HIGH TIDES
III remained  outstanding,  including  $115.0 million held by Calpine.  The HIGH
TIDES III are  scheduled to be  remarketed  no later than August 1, 2005. In the
event  of a  failed  remarketing,  the  relevant  HIGH  TIDES  III  will  remain
outstanding as convertible  securities at a term rate equal to the treasury rate
plus 6% per annum and with a term conversion  price equal to 105% of the average
closing  price of our common stock for the five  consecutive  trading days after
the  applicable  final  failed  remarketing  termination  date.  While a  failed
remarketing  of our HIGH  TIDES  III  would  not have a  material  effect on our
liquidity  position,  it would impact our  calculation  of diluted  earnings per
share  ("EPS")  and  increase  our  interest  expense.  Even  with a  successful
remarketing,  we would  expect to have an increased  dilutive  impact on our EPS
based on a revised conversion ratio.

     See Note 6 of the Notes to the Consolidated  Condensed Financial Statements
for more  information  related to other  financings  and  repurchases of various
issuances of debt in the first quarter of 2005.

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

     Operating  activities  for the three months ended March 31, 2005,  used net
cash of $114.6  million,  as compared  to $173.2  million for the same period in
2004. In the first quarter of 2005, there was an $82.8 million use of funds from
net changes in  operating  assets and  liabilities,  comprised  of  decreases in
accounts payable of $72.9 million, accrued payroll and related expenses of $23.1
million and $18.4 million in accrued  property taxes,  together with an increase
in net margin  deposits  posted to support  CES  contracting  activity  of $42.3
million. Offset against these, accounts receivable decreased by $61.1 million.

     In the first quarter of 2004, we had a $137.7 million use of funds from net
changes in  operating  assets and  liabilities,  comprised of an increase of $61
million  in net  margin  deposits,  an  increase  of  $23  million  in  accounts
receivable,  a use of  funds of $35  million  related  to  higher  payments  and
pre-payments of property tax and $19 million in higher prepaid long-term service
agreement payments.

     Investing  activities  for the three months ended March 31, 2005,  consumed
net cash of $ 220.8 million,  as compared to $71.4 million in the same period of
2004. Capital expenditures,  including capitalized interest,  for the completion
of our power facilities  decreased from $414.9 million in 2004 to $257.3 million
in 2005 as there were fewer projects under construction. Investing activities in
2005 also  reflected a $42.9  million  decrease in  restricted  cash.  Investing
activities in 2004  included the receipt of $176.9  million from the disposal of
the Lost Pines Power Plant and certain oil and gas  properties,  together with a
decrease in restricted cash of $346.3 million, offset by the purchase of the Los
Brazos Power Plant, the remaining 50% interest in the Aries Power Plant, and the
remaining 20% interest in Calpine Cogeneration Company's fleet of plants.

     Financing  activities  for the three months ended March 31, 2005,  provided
$368.7 million, as compared to a $160.1 million use of funds for the same period
in 2004.  We continued our  refinancing  program in the first quarter of 2005 by
raising $260.0 million from a preferred  security offering by Calpine Jersey II,
$144.7 million from various project financings and $213.1 million from a prepaid
commodity derivative contract at our Deer Park facility.  Also, we repaid $130.7
million of notes payable and project  financing debt, in addition to using $61.2
million to repay Senior Notes and to repurchase  Senior Notes due 2010 and 2011.
Additionally we incurred $47.9 million in financing and transaction costs.

     Working  Capital -- At March 31, 2005,  we had a negative  working  capital
balance of approximately  $299.1 million due primarily to (1) the classification
as current  liabilities  of the projected use of proceeds of $724.0  million for
bond purchase  requirements  (see Note 6 of the Notes to Consolidated  Financial
Statements  for a  discussion),  (2)  an  increase  of  $112.7  in  net  current
derivative  liabilities  from  December  31, 2004,  to March 31,  2005,  and (3)
negative operating cash flow for the three months ended March 31, 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 March 31, 2005 and December 31, 2004, we
had approximately $636.6 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,  $231.2 million and $233.3 million, respectively,
were in aggregate issued under the cash collateralized letter of credit facility
and the corporate  revolving  credit facility at March 31, 2005 and December 31,
2004, respectively.

     Commodity  Margin Deposits and Other Credit Support -- As of March 31, 2005
and December 31, 2004, to support  commodity  transactions  we had deposited net
amounts of $291.2 million and $248.9  million,  respectively,  in cash as margin
deposits  with third  parties,  and we made gas and power  prepayments  of $82.7
million, and $78.0 million,  respectively, and had letters of credit outstanding
of $109.0  million and $115.9  million,  respectively.  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 indentures and credit agreement  governing
the various tranches of our second-priority secured indebtedness  (collectively,
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." 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.  The following table sets forth selected balance sheet  information

subsidiaries  at March 31, 2005, and selected income  statement  information for

     Bankruptcy-Remote   Subsidiaries  --  Pursuant  to  applicable  transaction
agreements,  we have established  certain of our entities  separate from Calpine
and our other  subsidiaries.  At March 31, 2005 these entities  included:  Rocky
Mountain Energy Center,  LLC,  Riverside Energy Center,  LLC, Calpine  Riverside
Holdings,  LLC,  Calpine  Energy  Management,  L.P., CES GP, LLC, Power Contract
Financing,  LLC ("PCF"),  Power Contract Financing III, LLC ("PCF III"), Calpine
Northbrook Energy Marketing,  LLC, Calpine Northbrook Energy Marketing Holdings,
LLC ("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 -- Our various indentures
place  conditions  on our  ability  to  issue  indebtedness,  including  further
limitations  on the issuance of additional  debt if our interest  coverage ratio
(as defined in the various  indentures)  is below 2:1.  Currently,  our interest
coverage  ratio (as so defined) is below 2:1 and,  consequently,  our indentures
generally would not allow us 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  indentures  will limit our
ability to invest in unrestricted subsidiaries and non-subsidiary affiliates and
make certain  other types of  restricted  payments.  As of March 31,  2005,  our
interest coverage ratio (as so defined) was below 1.75:1. Furthermore, until the
ratio is greater than 1.75:1,  certain of the Company's indentures will prohibit
any further investments in non-subsidiary affiliates.

     Certain of our  indebtedness  issued in the last half of 2004 was permitted
under our  indentures on the basis that the proceeds would be used to repurchase
or  redeem  existing  indebtedness.   While  we  completed  a  portion  of  such
repurchases  during the fourth quarter of 2004 and the first quarter of 2005, we
are still in the process of completing the required amount of repurchases. While
the amount of indebtedness that must still be repurchased will ultimately depend
on the market price of our outstanding indebtedness at the time the indebtedness
is  repurchased,  based on current  market  conditions,  we estimate that, as of
March 31,  2005,  as  adjusted  for market  conditions  and  financial  covenant
calculations,  we would be required  to spend  approximately  $294.0  million in
order to fully  satisfy this  requirement.  This amount has been  classified  as
Senior Notes,  current  portion,  on our Consolidated  Condensed  Balance Sheet.
Subsequent to March 31, 2005, we have  satisfied a portion of such  requirement.
See Note 14 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 subsidiary  indebtedness,  in each case within 365 days of the
closing date of the transaction.  In light of this requirement,  and taking into
account  the amount of capital  expenditures  currently  budgeted  for 2005,  we
anticipate that subsequent to March 31, 2005, we will need to use  approximately
$250.0 of the net proceeds of the $360.0 million Two-Year  Redeemable  Preferred
Shares issued by our Calpine (Jersey) Limited ("Calpine Jersey I") subsidiary on
October 26, 2004,  and  approximately  $180.0 million of the net proceeds of the
$260.0 million  Redeemable  Preferred  Shares issued by our Calpine Jersey II on
January 31,  2005,  to  repurchase  or repay  certain  subsidiary  indebtedness.
Accordingly,  $430.0 million of long-term debt has been  reclassified  as Senior
Notes, current portion, on our Consolidated  Condensed Balance Sheet. The actual
amount of the net  proceeds  that will be required to be used to  repurchase  or
repay  subsidiary  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.

     The total  current  debt  obligation  as of March 31,  2005,  was  $1,510.7
million,  which  consisted of $1,199.1  million of April  through  December 2005
repayments  or  maturities  and $311.6  million  of the  $1,122.5  million  2006
repayments or maturities.

     As noted  above,  we have  significant  debt  maturities  or bond  purchase
requirements in 2005 as well as significant  debt maturities in 2006 and beyond.
During the first  quarter of 2005,  our cash flow from  operations  used  $114.6
million  and at March  31,  2005,  we had  negative  working  capital  of $299.1
million. In addition, as noted in Note 11 of the Notes to Consolidated Condensed
Financial Statements, certain bond holders have raised issues concerning the use
of proceeds from certain of the planned or recently executed transactions.

     We have  guaranteed  the  payment  of a portion  of the rents due under the
lease of the  Greenleaf  generating  facilities  in  California.  This  lease is
between  an owner  trustee  acting  on behalf of Union  Bank of  California,  as
lessor, and a Calpine subsidiary,  Calpine Greenleaf, Inc., as lessee. We do not
currently  meet  the  requirements  of a  financial  covenant  contained  in the
guarantee agreement.  The lessor has waived this non-compliance  through May 15,
2005, and we are currently in  discussions  with the lessor to modify the lease,
Our  guarantee  thereof,  and other  related  documents so as to  eliminate  the
covenant in question.  In the event the lessor's  waiver were to expire prior to
completion of this amendment,  the lessor could at that time elect to accelerate
the payment of certain  amounts  owing under the lease,  totaling  approximately
$16.0 million.  In the event the lessor were to elect to require us to make this
payment,  the lessor's remedy under the guarantee and the lease would be limited
to taking steps to collect  damages from us. The lessor would not be entitled to
terminate or exercise other remedies under the Greenleaf lease.

     In  connection   with  several  of  our   subsidiaries'   lease   financing
transactions (Agnews,  Geysers,  Greenleaf,  Pasadena,  Rumford/Tiverton,  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.

     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 the Company's 2004
Form 10-K, cash flow from  operations is currently  insufficient to meet in full
the Company's cash,  liquidity and refinancing  obligations for the year, so the
Company presently also depends in part upon its liquidity  enhancing program and
refinancing  program in order to fully service its debt. In addition,  financing
agreements  covering a  substantial  portion of the Company's  subsidiaries  and
other  affiliates  indebtedness,  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  March 31,  2005,  our
effective tax rate on continuing  operations decreased to 33% as compared to 41%
for the three months ended March 31, 2004. Our tax rate on continuing operations
for the  quarter  ended  March  31,  2004,  has been  restated  to  reflect  the
reclassification  to  discontinued  operations of certain tax expense  (benefit)
related  to the sale of our oil and gas  reserves  (see  Note 7 of the  Notes to
Consolidated  Condensed  Financial  Statements).   Our  effective  tax  rate  on
continuing  operations is based on the  consideration  of estimated  full fiscal
year earnings and the effect of significant  permanent differences in estimating
the quarterly effective rate, as well as establishing  valuation  allowances for
certain deferred tax assets.

     Asset  Sales  --  As  a  result  of  the  significant  contraction  in  the
availability  of  capital  for  participants  in  the  energy  sector,   we  are
considering  disposing of certain assets,  which serves  primarily to strengthen
our balance sheet through repayment of debt.

     Accordingly,  we are  evaluating  the potential  sale of our Saltend Energy
Centre.  We acquired the  1,200-MW  power plant,  located in Hull,  England,  in
August 2001 for  approximately  $800 million.  Net proceeds from any sale of the
facility would be used to redeem the existing $360 million  Two-Year  Redeemable
Preferred Shares and then to redeem the $260 million Redeemable Preferred Shares
due July 30, 2005. Any remaining  proceeds would be used in accordance  with the
asset sale provisions of our existing bond indentures.

     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 Special-Purpose Entities ("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 Accounting Principles Board ("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 March 31, 2005,  third party
investee debt was approximately  $220.3 million.  Of this amount,  $59.6 million
relates to our investment in AELLC,  for which the cost method of accounting was
used as of December 31, 2004. See following paragraph for a discussion of AELLC.
Based on our pro rata  ownership  share of each of the  investments,  our  share
would be approximately  $86.2 million.  This amount includes the Company's share
for AELLC of $19.2 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.  See Note 5 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 and has construction  debt of $59.6 million  outstanding
as of March 31,  2005.  The debt is  non-recourse  to Calpine  Corporation  (the
"AELLC  Non-Recourse  Financing").  On  November  3, 2004,  a jury  verdict  was
rendered  against AELLC in a breach of contract  dispute with IP. See Note 11 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.  See Note 14 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.  The ratings for the following debt issues  remained  unchanged:
the BBB- SPUR rating on Gilroy Energy Center bonds,  the BB- rating on the Rocky
Mountain Energy Center and the Riverside Energy Center loans, the CCC+ rating on
the third lien  CalGen debt and the BBB rating on the Power  Contract  Financing
LLC bonds. Such downgrade could increase the cost of future borrowings and other
costs of doing business.

     On October 4, 2004,  Fitch, Inc. assigned our first priority senior secured
debt a rating of BB-. At that time,  Fitch also  downgraded our second  priority
senior secured debt from BB- to B+,  downgraded our senior unsecured debt rating
from B- to CCC+,  and  reconfirmed  our preferred  stock rating at CCC.  Fitch's
rating outlook for the Company is stable.

     Moody's  Investors  Service  currently has a senior  implied  rating on the
Company of B2 (with a stable  outlook),  and they rate our senior unsecured debt
at Caa1, and our preferred stock at Caa3.

     Many other issuers in the power generation sector have also been downgraded
by one or more of the ratings  agencies during this period.  Such downgrades can
have a  negative  impact  on our  liquidity  by  reducing  attractive  financing
opportunities  and  increasing  the  amount of  collateral  required  by trading
counterparties.

<FN>
(1)  Construction in Progress ("CIP")

(2)  There are a total of eight projects in active  construction.  This includes
     the seven  projects  that are  recorded  in CIP in the table  above and one
     project that is recorded in unconsolidated investments.
</FN>


     Projects  in  Active   Construction   --  The  seven   projects  in  active
construction are projected to come on line from May 2005 to November 2007. These
projects will bring on line approximately  2,878 MW of base load capacity (3,210
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 March 31, 2005,  the total  projected  costs to complete  these
projects is $843.7 million and the estimated  funding  requirements  to complete
these projects,  net of expected project  financing  proceeds,  is approximately
$48.3 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  will  bring  on  line
approximately  1,769 MW of base load capacity (2,035 MW with peaking  capacity).
We expect to finance the remaining  $340.8 million  projected  costs to complete
these projects.

     Projects in Advanced  Development -- There are eleven  projects in advanced
development.  These projects will bring on line  approximately  5,072 MW of base
load capacity (6,150 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.  The estimated  cost to complete the eleven  projects in
advanced  development  is  approximately  $3.1  billion.  Our current plan is to
project finance these costs as PPAs are arranged.

     Suspended   Development   Projects  --  Due  to  current   electric  market
conditions,  we have ceased  capitalization of additional  development costs and
interest  expense on six 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 the  recoverable
value.  These projects would bring on line  approximately  2,956 MW of base load
capacity (3,409 MW with peaking capacity).  The estimated cost to complete these
projects is approximately $1.8 billion.

     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, oil and gas and geothermal  resource and
facilities development as well as software developed for internal use.

     Unassigned Equipment -- As of March 31, 2005, we had made progress payments
on four turbines and other  equipment with an aggregate  carrying value of $66.2
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.  We are  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  our
engineering and construction services.

     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  "Accounting  for  Impairment or Disposal of Long-Lived  Assets"
("SFAS No. 144").  We review our unassigned  equipment for potential  impairment
based on  probability-weighted  alternatives of utilizing it for future projects
versus  selling it.  Utilizing  this  methodology,  we do not  believe  that the
equipment not committed to sale is impaired.  However,  during the quarter ended
March 31, 2004, we recorded to the "Equipment  cancellation and impairment cost"
line of the  Consolidated  Condensed  Statement  of  Operations  $2.4 million in
losses in  connection  with  equipment  cancellations,  and we may incur further
losses should we decide to cancel more  equipment  contracts or sell  unassigned
equipment  in the future.  In the event we were unable to obtain PPAs or project
financing  and  suspension  or  abandonment  were to  result,  we  could  suffer
substantial impairment losses on such projects.

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 hedging,  balancing
     and  optimization  ("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" ("EITF
     Issue  No.  03-11"),  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 British
     Thermal Units ("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's 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 "equity" gas from Calpine Natural
     Gas,  which is  eliminated  in  consolidation),  and the spread on sales of
     purchased gas for hedging,  balancing, and optimization activity by (b) the
     heat  content in  millions  of Btu's of the fuel we  consumed  in our power
     plants for the period.

o    Average  spark  spread  expressed  in dollars per MWh  generated.  Our risk
     management  activities focus on managing the spark spread for our portfolio
     of power  plants,  the  spread  between  the sales  price  for  electricity
     generated  and the cost of fuel.  We  calculate  the spark  spread  per MWh
     generated by  subtracting  (a) adjusted  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 plant  operating  expense  ("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's. 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

California Power Market

     The  volatility  in the  California  power  market  from  mid-2000  through
mid-2001 has produced significant unanticipated results, and as described in the
following risk factors,  the unresolved issues arising in that market,  where 42
of our 103 power plants are located, could adversely affect our performance.

     We may be required to make refund payments to the California Power Exchange
("CalPX") and California  Independent  System Operator  ("CAISO") as a result of
the California  Refund  Proceeding.  On August 2, 2000,  the  California  Refund
Proceeding  was initiated by a complaint made at FERC by SDG&E under Section 206
of the FPA 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.  We believe,
based  on the  information  that we have  analyzed  to  date,  that  any  refund
liability that may be attributable to us 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.  We believe we
have  appropriately  reserved  for the  refund  liability  that  by our  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,  we are unable to predict the
timing of the  completion of these  proceedings  or the final refund  liability.
Thus, the impact on our 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,  The  Williams  Companies,  Inc.  ("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.

     We have been  mentioned in a show cause order in  connection  with the FERC
investigation into western markets regarding the CalPX and CAISO tariffs and may
be found liable for payments thereunder. 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 hour 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.  We believe  that we did not violate the CAISO and CalPX tariff
prohibitions  referred  to by FERC in this  order;  however,  we are  unable  to
predict  at this time the final  outcome  of this  proceeding  or its  impact on
Calpine.

     The  energy  payments  made to us  during a  certain  period  under  our QF
contracts with PG&E may be retroactively adjusted downward as a result of a CPUC
proceeding.  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,  our 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 who  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. We believe that the CalPX Price was
the appropriate  price for energy  payments for our QFs during this period,  but
there can be no assurance that this will be the outcome of the CPUC proceedings.

     The  availability  payments made to us under our Geysers'  Reliability Must
Run contracts have been challenged by certain buyers as having been not just and
reasonable.  CAISO,  California  Electricity  Oversight Board,  Public Utilities
Commission of the State of  California,  PG&E,  SDG&E,  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 FPA
Section  206  proceeding  to  challenge  one  component  of a number of separate
settlements  previously reached on the terms and conditions of "reliability must
run" contracts  ("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. To date,  FERC has not  established a
Section 206  proceeding.  The outcome of this  litigation  and the impact on our
business cannot be determined at the present time.

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.

   Total....................................  $  (328,743)  $   (628,140)

     Derivative  commodity  instruments included in the table are those included
in Note 8 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  ten percent
adverse price change regardless of term or historical  relationship  between the
contract price of an instrument and the underlying commodity price. In the event
of an actual  ten  percent  change in prices,  the fair value of our  derivative
portfolio  would  typically  change by more than ten percent for earlier forward
months and less than ten percent for later forward  months because of the higher
volatilities  in the near term and the effects of  discounting  expected  future
cash flows.

     The primary  factors  affecting  the fair value of our  derivatives  at any
point in time are (1) the volume of open derivative  positions  (MMBtu and MWh),
and (2) changing  commodity  market  prices,  principally  for  electricity  and
natural gas. The total volume of open gas derivative  positions increased by 76%
from  December 31, 2004,  to March 31, 2005,  and the total volume of open power
derivative  positions  increased by 125% 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"  ("SFAS No. 133"),  the change since the last balance sheet
date in the total value of the  derivatives  (both  assets and  liabilities)  is
reflected  either in OCI, net of tax, or in the  statement of  operations  as an
item (gain or loss) of current  earnings.  As of March 31, 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 months ended March 31,
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

     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 March 31, 2005, the impact
to our pre-tax  earnings  that would be expected  after a 10% adverse  change in
exchange rates is shown in the table below (in thousands):

     Significant  changes  in  exchange  rates will also  impact our  Cumulative
Translation Adjustment ("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.

Foreign Currency Transaction Gain (Loss)

     The  major  components  of our  foreign  currency  transaction  gains  from
continuing operations of $5.2 million and $10.0 million,  respectively,  for the
three  months  ended  March 31,  2005 and  2004,  respectively,  are as  follows
(amounts in millions):

                                                      2005       2004

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

     The  $Cdn-$US  gain for the three  months  ended  March 31,  2005,  was due
primarily to a  strengthening  of the U.S.  dollar  against the Canadian  dollar
during the first 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 first
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 March 31, 2004 was moderate
despite  the fact that the U.S.  dollar  strengthened  considerably  against the
Canadian  dollar during the first 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
March 31, 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 $0.7 million loss was
due to  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.

     During  the  three  months  ended  March  31,  2005  and  March  31,  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 GBP-$US  loss for the three  months  ended  March 31,  2005  relates to
re-measurement  gains  associated  with our US$360 million  Two-Year  Redeemable
Preferred  Shares  issued  in  October  2004  by  our  indirect,   wholly  owned
subsidiary,  Calpine (Jersey) Limited.  The remeasurement losses recognized were
driven by a significant  weakening of the GBP against the U.S. dollar during the
first quarter of 2005. There is no comparable  amount for the three months ended
March  31,  2004  as no such  exposure  existed  prior  to the  closing  of this
offering.

     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 March 31, 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 March 31, 2005.  All fair market values are
shown net of applicable premium or discount, if any (dollars in thousands):

New Accounting Pronouncements

     See Note 2 of the Notes to Consolidated  Condensed Financial Statements for
a discussion of new accounting pronouncements.

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.

     Calpine  Corporation  (the  "Company")  maintains  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 Securities and Exchange  Commission  rules and forms, and that such
information  is  accumulated  and  communicated  to  the  Company's  management,
including  its  Chief  Executive  Officer  and  Chief  Financial   Officer,   as
appropriate, to allow timely decisions regarding required disclosure.

     As of December 31, 2004,  management  of the Company  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
quarter of 2005,  the Company  began  taking the steps  necessary to improve its
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 be able to complete  the
required   testing  and  to  conclude  that  they  are  designed  and  operating
effectively.

     The Company's  senior  management,  including the Company's Chief Executive
Officer  and  Chief  Financial  Officer,  evaluated  the  effectiveness  of  the
Company's 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  discussed below, the Company's Chief Executive  Officer along with the
Company's  Chief  Financial  Officer  concluded  that the  Company's  disclosure
controls and  procedures are not  effective.  In light of the material  weakness
identified  as of December  31, 2004,  and that  continues to exist at March 31,
2005,  the Company  continued to perform  additional  analysis and  post-closing
procedures  to ensure its  consolidated  financial  statements  are  prepared in
accordance with generally accepted accounting principles ("GAAP").  Accordingly,
management believes that the financial statements included in this report fairly
present in all material respects the Company's financial  condition,  results of
operations and cash flows for the periods presented.  The certificates  required
by this item are filed as Exhibits 31.1 and 31.2 to this Form 10-Q.

Status of Remediation of the Material Weakness

     During  the first  quarter  of 2005,  the  Company  began  taking the steps
necessary  to improve its  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. The
Company has hired  additional  resources and has engaged third party tax experts
to improve the  effectiveness  of the controls over  management's  review of the
details  of the income tax  calculations.  The  Company  has also  improved  the
process of preparing  and reviewing the  workpapers  supporting  its tax related
calculations and conclusions.

    The Company will continue to do the following:

o    Complete the implementation of the CorpTax computer application 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.

     While  certain  elements  of the  program  to  remediate  the tax  material
weakness  are  still  underway.   The  Company  will  continue  to  monitor  the
effectiveness  of  these  procedures  and  continue  to make  any  changes  that
management deems appropriate.

Changes in Internal Control Over Financial Reporting

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