ITEM 2.01 -- COMPLETION OF ACQUISITION OR DISPOSITION OF ASSETS

     On July 28, 2005, Calpine Corporation ("Calpine") and its indirect,  wholly
owned  subsidiaries  Calpine UK Holdings  Limited (the  "Seller"),  and Quintana
Canada Holdings, LLC (the "Seller Guarantor",  and, collectively with the Seller
and Calpine,  the "Seller  Parties"),  sold the entire  issued share  capital of
Saltend  Cogeneration Company Limited ("SCCL") and Calpine UK Operations Limited
("UK OpCo",  together  with SCCL,  the "Sale  Group") to  Normantrail  (UK CO 3)
Limited (the  "Purchaser"),  a  partnership  formed by  International  Power PLC
("IPR"), Mitsui & Co., Ltd. ("Mitsui") pursuant to the terms of a share sale and
purchase  agreement (the "Agreement")  among the Seller Parties,  the Purchaser,
IPR and  Mitsui.  SCCL is the  owner of,  and UK OpCo is the  operator  of,  the
Saltend  Energy  Centre,  a 1200 MW  (nominal)  natural  gas-fired  cogeneration
facility located in Hull,  England.  Pursuant to the Agreement,  Calpine and the
Seller have provided  certain  customary  warranties  and  indemnities,  and the
Seller  Guarantor has  guaranteed  the payment by the Seller of  liabilities  in
respect  of all claims  under the  Agreement  other than  claims for breach of a
warranty.  The  obligations of the Purchaser are guaranteed as to 70% by IPR and
30% by Mitsui.  A copy of the  Agreement  was filed as an  exhibit to  Calpine's
Current  Report on Form 8-K dated May 28,  2005,  filed  with the SEC on June 3,
2005.

     The total amount  payable by the  Purchaser  under the Agreement is British
pounds  ("GBP")  498.4 million  comprising an amount  payable for the Sale Group
shares and an amount to repay  intercompany loans made to SCCL by certain of its
affiliates.  The  purchase  price is subject to a GBP for GBP  post-closing  net
working capital adjustment,  subject to an upwards cap determinable on the basis
of completion accounts prepared in accordance with the procedures set out in the
Agreement.  GBP 20 million of the  purchase  price has been placed in escrow and
will be retained for one year following  closing of the sale,  provided that the
Seller will be entitled  to receive  GBP 5 million  from the escrow  every three
months,  subject to the Purchaser  making any claims under the Agreement in such
period,  which claims may be satisfied from amounts in escrow. The net proceeds,
after the  redemption  of two of our  existing  series of  Redeemable  Preferred
Shares  described in Item 2.04 below, and the reasonable  transaction  costs and
adjustments  associated  with this sale,  are being  held  under the  control of
Calpine's  subsidiary  Calpine Canada  Resources  Company pursuant to an Interim
Order issued by the Supreme Court of Nova Scotia,  pending a Final Order, in the
litigation  commenced in May 2005 by Harbert Distressed  Investment Master Fund,
Ltd. Pursuant to an August 2, 2005, decision by the Court in the case, the Court
stated its intention to issue a Final Order which would,  in effect,  adjust the
amount  required to be so held so that it will be  sufficient  to cover the face
amount of certain qualifying Calpine-guaranteed bonds of our subsidiary, Calpine
Canada Energy Finance II ULC. The qualifying  bonds will be those purchased by a
bondholder  (other than certain  Calpine  entities)  prior to September 1, 2004,
that continues to hold those bonds on August 2, 2005.

     As a part of the sale,  we have agreed to reimburse the Purchaser for up to
GBP 2  million  of  carbon  emission  credits  purchased  by  SCCL  in the  year
immediately  following  the  close  of  the  sale.  Under  recently  adopted  EU
legislation,  SCCL  and  other  power  generators  in the  United  Kingdom  were
allocated a certain  number of carbon  emission  credits at the beginning of the
year; to the extent that their carbon  emissions  exceed the amounts  allocated,
companies are required to purchase  additional  carbon  emission  credits in the
open market.  Such  reimbursement  will be deducted from the final GBP 5 million
quarterly  escrow payment.  In  anticipation of this expense,  we will record an
accrued liability in the amount of GBP 2 million, which will reduce our expected
gain on the disposition.

     The sale closed on July 28, 2005.  For further  information  on the sale of
the Saltend  Energy  Centre,  see the Form 8-K dated May 28, 2005,  and filed on
June 3, 2005.  A copy of the  Agreement  was filed as an exhibit to our Form 8-K
dated June 17, 2005, and filed on June 23, 2005.


ITEM 2.04 -- TRIGGERING EVENTS THAT ACCELERATE A DIRECT FINANCIAL  OBLIGATION OR
             AN OBLIGATION UNDER AN OFF-BALANCE SHEET ARRANGEMENT

     The  information  in Item 2.01 above is  incorporated  by reference in this
Item 2.04. In  connection  with the sale of SCCL, we were required to redeem two
of our existing series of Redeemable Preferred Shares totaling $620 million. The
redemption  of each series of Redeemable  Preferred  Shares was effected on July
28,  2005,  with a  portion  of the  proceeds  of the sale of SCCL.  The  series
redeemed  comprise $360 million of Redeemable  Preferred  Shares due October 15,
2006,  which were  redeemed  at a price of 103% of par plus  accrued  and unpaid
interest to and including the date of redemption, and $260 million of Redeemable
Preferred  Shares due July 30, 2005,  which were  redeemed at a price of 100% of
par plus accrued and unpaid  interest to and including  the date of  redemption.
The information in Item 2.03 of our Current Report on Form 8-K dated October 26,
2004,  filed with the SEC on November 5, 2004,  which  contains a description of
the  Redeemable  Preferred  Shares due October 15, 2006, and in Item 2.03 of our
Current  Report  on Form 8-K  dated  February  1,  2005,  filed  with the SEC on
February 3, 2005,  which  contains a  description  of the  Redeemable  Preferred
Shares due July 30, 2005, are incorporated by reference herein.


ITEM 8.01 -- OTHER EVENTS

     On July 7, 2005, the Registrant issued the press release attached hereto as
Exhibit 99.1.


ITEM 9.01 -- FINANCIAL STATEMENTS AND EXHIBITS

     (a) Financial Statements of Businesses Acquired.

     Not Applicable

     (b) Pro Forma Financial Information.

     As  disclosed  in Item 2.01 of this 8-K,  on July 28,  2005,  we closed the
disposition  of Saltend  Cogeneration  Company  Limited  ("SCCL") and Calpine UK
Operations  Limited ("UK OpCo" or "Saltend").  In addition,  as disclosed in our
Form 8-K dated July 7, 2005 and filed on July 13, 2005,  on July 7, 2005, we and
the  counterparty  entered  into and closed a Purchase and Sale  Agreement  with
Rosetta,  the  buyer,  pursuant  to  which  we sold  our  remaining  oil and gas
properties  ("oil and gas").  Upon  closing of the sale,  the  Company no longer
holds  any oil and gas  reserves,  with the  exception  of  certain  oil and gas
properties  valued at $75 million for which we were unable to obtain consents to
assignment  prior to  closing  but expect to do so in the near  future.  The pro
forma financial  information  below gives effect to the oil and gas sale and the
disposition of SCCL and UK OpCo,  both of which will be accounted for as of June
30, 2005, as  discontinued  operations in accordance  with Financial  Accounting
Standards Board ("FASB")  Statement of Financial  Accounting  Standards ("SFAS")
No. 144, "Accounting for the Impairment or Disposal of Long-Lived Assets" ("SFAS
No. 144").

     The unaudited Pro Forma Consolidated Condensed Statements of Operations are
presented for the three months ended March 31, 2005 and the years ended December
31, 2004, 2003 and 2002 and present Calpine's  operations as if the transactions
described  above had  occurred  at January 1, 2002.  Basic  earnings  (loss) per
common share were computed by dividing net income (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.   An  unaudited  Pro  Forma
Consolidated  Condensed  Balance Sheet as of March 31, 2005, is also  presented.
The  unaudited  Pro Forma  Consolidated  Condensed  Balance  Sheet  presents the
property sales described above, as if they had occurred at March 31, 2005.

     The unaudited Pro Forma Consolidated  Condensed Financial Statements should
be read in  conjunction  with Calpine's  Financial  Statements and related Notes
included in Calpine's  Report on Form 10-Q for the quarter  ended March 31, 2005
and the Report on Form 10-K for the year ended  December 31, 2004 filed with the
Securities and Exchange Commission.

<FN>
(1)  The Pro Forma  Consolidated  Condensed  Balance Sheet  reflects the Oil and Gas  disposition as if it had occurred on March 31,
     2005.

(2)  The Pro Forma  Consolidated  Condensed Balance Sheet also reflects the disposition of SCCL and UK OpCo as if it had occurred on
     March 31, 2005.

(3)  Represents  the  proceeds  from the sale that are  expected  to be $1.05  billion  before (a)  approximately  $11.5  million of
     additional  holdbacks and adjustments for operations from the transaction  date, (b)  approximately  $60.6 million of estimated
     transaction  fees and  expenses,  (c) certain oil and gas  properties  valued at $75 million for which we were unable to obtain
     consents to  assignment  prior to closing but expect to do so in the near future and (d) accrued  interest of $6.8  million and
     after the $138.9 million in repayment of Senior Notes.

(4)  Represents $75 million of the purchase price that was withheld for non-consent properties.

(5)  Adjustment  represents  the asset and  liability  balances  of SCCL and UK OpCo or Oil and Gas which will  reduce our asset and
     liability  positions upon completion of the  dispositions as well as the addition of certain  accruals for adjustments and exit
     costs necessitated by the respective structures of these transactions.

(6)  Adjustment represents the write-off of unamortized financing costs associated with the repayment of Senior Notes as part of the
     use of proceeds.

(7)  Adjustment represents the repayment of Senior notes as part of the use of the proceeds, as well as associated accrued interest.

(8)  Represents  taxes at the statutory rate of 38% on the estimated  non-recurring  pre-tax gain of $359.4 million.  See Note 9 for
     further information.

(9)  Represents  the  anticipated  non-recurring  gain of $222.8 million (net of taxes of $136.6 million at a statutory rate of 38%)
     after consideration of fees,  contingencies and excess office space write-off.  This non-recurring gain is an estimate based on
     our Consolidated  Condensed Balance Sheet at March 31, 2005. This estimate does not take into  consideration our actual results
     of operations and certain other changes to the  Consolidated  Condensed  Balance Sheet that occurred after March 31, 2005 until
     the closing date of the transaction. We estimate that these changes will increase the final pre-tax gain to $350.0 million.

(10) Adjustment  represents the anticipated cash proceeds of the sale of SCCL and UK OpCo of $828.2 million, less the cost to redeem
     the  principal,  interest and  termination  fees of $647.0  million  associated  with two of our existing  series of Redeemable
     Preferred Shares and direct costs associated with the sale of $8.3 million.

(11) Adjustment represents the write-off of unamortized financing costs of $12.9 million and $7.2 million, respectively,  associated
     with two of our existing series of Redeemable  Preferred  Shares which will be redeemed with the proceeds from the sale of SCCL
     and UK OpCo.

(12) Adjustment  represents the redemption of two of our existing series of Redeemable  Preferred  Shares totaling $620 million,  as
     well as associated accrued interest of $11.9 million and early termination fees of $10.8 million.

(13) Adjustment  represents an estimated  non-recurring  gain  associated with the transaction of $3.8 million (net of taxes of $1.6
     million at a statutory rate of 30%) after consideration of fees,  contingencies and costs associated with the redemption of two
     of our existing  series of Redeemable  Preferred  Shares.  This non- recurring  gain is an estimate  based on our  Consolidated
     condensed Balance Sheet at March 31, 2005. This estimate does not take into  consideration our actual results of operations and
     certain other changes to the Consolidated  Condensed Balance Sheet that occurred after March 31, 2005 until the closing date of
     the transaction. We estimate that these changes will increase the final pre-tax gain to $6.0 million.

(14) Adjustment  represents the cumulative balance of "out of the money" cash flow hedges held by SCCL of $39.4 million that will be
     written  off as a result  of the sale of SCCL and UK OpCo and the  realization  into  earnings  of the  Cumulative  Translation
     Adjustment ("CTA") of $257.6 million associated with the Company's GBP-denominated entities as a result of the sale of SCCL and
     UK OpCo.

(15) Represents  the impact of sales  proceeds from SCCL and UK OpCo to be held in escrow and amounts  anticipated  to reimburse the
     Seller for anticipated carbon emission credits as described in Item 2.01 and other indemnification and exit liabilities.  Total
     proceeds to be held in escrow will be approximately $34.6 million;  these proceeds are presented on the Consolidated  Condensed
     Balance Sheet as restricted  cash. The total amount we expect to accrue for the carbon emission  credits is $3.5 million (based
     on current exchange rates),  and the total estimated  liability for other  indemnification  and exit liabilities is $3 million.
     These estimated accruals are presented on the Consolidated Condensed Balance Sheet within other current liabilities.

(16) Represents an additional liability of 1% of the gross sales proceeds, or $10.5 million, as an allowance for indemnification and
     exit liabilities, and also other miscellaneous transaction fees of $2.2 million.

(17) Represents taxes of $1.6 million at the statutory rate of 30% associated with the estimated  non-recurring pre-tax gain of $5.4
     million. See Note 13 for further information.

(1)  The Pro Forma Consolidated  Condensed  Statement of Operations assumes that Oil and Gas was sold by Calpine on January 1, 2002.
     The results of these assets have been removed from the Pro Forma Consolidated Condensed Statement of Operations.  The estimated
     non-recurring gain associated with the sales transaction is not included within the Pro Forma Consolidated  Condensed Statement
     of Operations. See Note 9 to the Unaudited Pro Forma Consolidated Condensed Balance Sheet for further information.

(2)  The Pro Forma Consolidated  Condensed  Statement of Operations assumes that SCCL and UK OpCo were sold by Calpine on January 1,
     2002. The results of SCCL and UK OpCo have been removed from the Pro Forma Consolidated Condensed Statement of Operations.  The
     estimated  non-recurring gain associated with the sales transaction is not included within the Pro Forma Consolidated Condensed
     Statement of Operations. See Note 13 to the Unaudited Pro Forma Consolidated Condensed Balance Sheet for further information.

(3)  Adjustment represents activity that was reclassified to discontinued operations as a result of the sale of the Domestic Oil and
     Gas Properties or SCCL and UK OpCo.

(4)  The Pro Forma  adjustments in the Unaudited Pro Forma  Consolidated  Condensed  Statement of Operations  include certain sales,
     general and  administrative  expenses  allocated  to Oil and Gas and to SCCL and UK OpCo based on a  proportion  of base wages.
     Accordingly,  these expenses have been included within the Oil and Gas and the SCCL and UK OpCo income figures to determine the
     Pro Forma totals.  For the year ended December 31, 2004,  these expenses  totaled $0.7 million and $0.6 million for Oil and Gas
     and for SCCL and UK OpCo, respectively.

(5)  The Pro Forma  adjustments also include  interest  expense that we expect to allocate to discontinued  operations in accordance
     with Emerging Issues Task Force ("EITF") Issue No. 87-24,  "Allocation of Interest to Discontinued Operations" ("EITF Issue No.
     87-24").  We  include  interest  expense  on debt  which is  required  to be repaid as a result of a  disposal  transaction  in
     discontinued  operations.  Additionally,  other  interest  expense that cannot be attributed to other  operations of Calpine is
     allocated  based on the  ratio of net  assets to be sold less  debt  that is  required  to be paid as a result of the  disposal
     transaction  to the sum of total net  assets of  Calpine  plus the  consolidated  debt of  Calpine,  excluding  (a) debt of the
     discontinued  operation  that  will be  assumed  by the  buyer,  (b) known  debt that will be paid as a result of the  disposal
     transaction and (c) debt that can be directly  attributed to other operations of Calpine.  For the three months ended March 31,
     2005, the interest expense  allocated  within the Unaudited Pro Forma  Consolidated  Condensed  Statement of Operations is $4.9
     million and $12.5 million for Oil and Gas and for SCCL and UK OpCo, respectively.

(6)  The Oil and Gas Pro Forma  adjustments in the Pro Forma  Consolidated  Condensed  Statement of Operations are tax effected at a
     rate of 38%,  which  represents  Calpine's  statutory  tax rate in the United States for those assets.  Actual  adjustments  to
     Calpine's Consolidated Financial Statements to reflect this disposition may reflect a different effective tax rate.

(7)  Represents income before discontinued operations and cumulative effect of a change in accounting principle.

(8)  The Saltend Pro Forma adjustments in the Pro Forma Consolidated Condensed Statement of Operations are tax effected at a rate of
     30%,  which  represents  Calpine's  statutory tax rate in the United  Kingdom.  Actual  adjustments  to Calpine's  Consolidated
     Financial Statements to reflect this disposition may reflect a different effective tax rate.

(1)  The Pro Forma Consolidated  Condensed  Statement of Operations assumes that Oil and Gas was sold by Calpine on January 1, 2002.
     The results of these assets have been removed from the Pro Forma Consolidated Condensed Statement of Operations.  The estimated
     non-recurring gain associated with the sales transaction is not included within the Pro Forma Consolidated  Condensed Statement
     of Operations. See Note 9 to the Unaudited Pro Forma Consolidated Condensed Balance Sheet for further information.

(2)  The Pro Forma Consolidated  Condensed  Statement of Operations assumes that SCCL and UK OpCo were sold by Calpine on January 1,
     2002. The results of SCCL and UK OpCo have been removed from the Pro Forma Consolidated Condensed Statement of Operations.  The
     estimated  non-recurring gain associated with the sales transaction is not included within the Pro Forma Consolidated Condensed
     Statement of Operations. See Note 13 to the Unaudited Pro Forma Consolidated Condensed Balance Sheet for further information.

(3)  Adjustment represents activity that was reclassified to discontinued operations as a result of the sale of the Domestic Oil and
     Gas Properties or SCCL and UK OpCo.

(4)  The Pro Forma  adjustments in the Unaudited Pro Forma  Consolidated  Condensed  Statement of Operations  include certain sales,
     general and  administrative  expenses  allocated  to Oil and Gas and to SCCL and UK OpCo based on a  proportion  of base wages.
     Accordingly,  these expenses have been included within the Oil and Gas and the SCCL and UK OpCo income figures to determine the
     Pro Forma totals.  For the year ended December 31, 2004,  these expenses  totaled $2.9 million and $1.7 million for Oil and Gas
     and for SCCL and UK OpCo, respectively.

(5)  The Pro Forma  adjustments also include  interest  expense that we expect to allocate to discontinued  operations in accordance
     with Emerging Issues Task Force ("EITF") Issue No. 87-24,  "Allocation of Interest to Discontinued Operations" ("EITF Issue No.
     87-24").  We  include  interest  expense  on debt  which is  required  to be repaid as a result of a  disposal  transaction  in
     discontinued  operations.  Additionally,  other  interest  expense that cannot be attributed to other  operations of Calpine is
     allocated  based on the  ratio of net  assets to be sold less  debt  that is  required  to be paid as a result of the  disposal
     transaction  to the sum of total net  assets of  Calpine  plus the  consolidated  debt of  Calpine,  excluding  (a) debt of the
     discontinued  operation  that  will be  assumed  by the  buyer,  (b) known  debt that will be paid as a result of the  disposal
     transaction and (c) debt that can be directly attributed to other operations of Calpine.  For the year ended December 31, 2004,
     the interest expense allocated within the Unaudited Pro Forma Consolidated  Condensed  Statement of Operations is $12.4 million
     and $14.6 million for Oil and Gas and for SCCL and UK OpCo, respectively.

(6)  The Oil and Gas Pro Forma  adjustments in the Pro Forma  Consolidated  Condensed  Statement of Operations are tax effected at a
     rate of 38%,  which  represents  Calpine's  statutory  tax rate in the United States for those assets.  Actual  adjustments  to
     Calpine's Consolidated Financial Statements to reflect this disposition may reflect a different effective tax rate.

(7)  Represents income before discontinued operations and cumulative effect of a change in accounting principle.

(8)  The Saltend Pro Forma adjustments in the Pro Forma Consolidated Condensed Statement of Operations are tax effected at a rate of
     30%,  which  represents  Calpine's  statutory tax rate in the United  Kingdom.  Actual  adjustments  to Calpine's  Consolidated
     Financial Statements to reflect this disposition may reflect a different effective tax rate.

(1)  The Pro Forma Consolidated  Condensed  Statement of Operations assumes that Oil and Gas was sold by Calpine on January 1, 2002.
     The results of these assets have been removed from the Pro Forma Consolidated Condensed Statement of Operations.  The estimated
     non-recurring gain associated with the sales transaction is not included within the Pro Forma Consolidated  Condensed Statement
     of Operations. See Note 9 to the Unaudited Pro Forma Consolidated Condensed Balance Sheet for further information.

(2)  The Pro Forma Consolidated  Condensed  Statement of Operations assumes that SCCL and UK OpCo were sold by Calpine on January 1,
     2002. The results of SCCL and UK OpCo have been removed from the Pro Forma Consolidated Condensed Statement of Operations.  The
     estimated  non-recurring gain associated with the sales transaction is not included within the Pro Forma Consolidated Condensed
     Statement of Operations. See Note 13 to the Unaudited Pro Forma Consolidated Condensed Balance Sheet for further information.

(3)  Adjustment represents activity that was reclassified to discontinued operations as a result of the sale of the Domestic Oil and
     Gas Properties or SCCL and UK OpCo.

(4)  The Pro Forma  adjustments in the Unaudited Pro Forma  Consolidated  Condensed  Statement of Operations  include certain sales,
     general and  administrative  expenses  allocated  to Oil and Gas and to SCCL and UK OpCo based on a  proportion  of base wages.
     Accordingly,  these expenses have been included within Oil and Gas and the SCCL and UK OpCo income figures to determine the Pro
     Forma totals.  For the year ended December 31, 2003,  these expenses  totaled $3.3 million and $2.1 million for Oil and Gas and
     for SCCL and UK OpCo, respectively.

(5)  The Pro Forma  adjustments also include  interest  expense that we expect to allocate to discontinued  operations in accordance
     with Emerging Issues Task Force ("EITF") Issue No. 87-24,  "Allocation of Interest to Discontinued Operations" ("EITF Issue No.
     87-24").  We  include  interest  expense  on debt  which is  required  to be repaid as a result of a  disposal  transaction  in
     discontinued  operations.  Additionally,  other  interest  expense that cannot be attributed to other  operations of Calpine is
     allocated  based on the  ratio of net  assets to be sold less  debt  that is  required  to be paid as a result of the  disposal
     transaction  to the sum of total net  assets of  Calpine  plus the  consolidated  debt of  Calpine,  excluding  (a) debt of the
     discontinued  operation  that  will be  assumed  by the  buyer,  (b) known  debt that will be paid as a result of the  disposal
     transaction and (c) debt that can be directly attributed to other operations of Calpine.  For the year ended December 31, 2003,
     the interest expense allocated within the Unaudited Pro Forma  Consolidated  Condensed  Statement of Operations is $7.3 million
     and $7.2 million for Oil and Gas and for SCCL and UK OpCo, respectively.

(6)  The Oil and Gas Pro Forma  adjustments in the Pro Forma  Consolidated  Condensed  Statement of Operations are tax effected at a
     rate of 38%,  which  represents  Calpine's  statutory  tax rate in the United States for those assets.  Actual  adjustments  to
     Calpine's Consolidated Financial Statements to reflect this disposition may reflect a different effective tax rate.

(7)  Represents income before discontinued operations and cumulative effect of a change in accounting principle.

(8)  The Saltend Pro Forma adjustments in the Pro Forma Consolidated Condensed Statement of Operations are tax effected at a rate of
     30%,  which  represents  Calpine's  statutory tax rate in the United  Kingdom.  Actual  adjustments  to Calpine's  Consolidated
     Financial Statements to reflect this disposition may reflect a different effective tax rate.

(1)  The Pro Forma Consolidated  Condensed  Statement of Operations assumes that Oil and Gas was sold by Calpine on January 1, 2002.
     The results of these assets have been removed from the Pro Forma Consolidated Condensed Statement of Operations.  The estimated
     non-recurring gain associated with the sales transaction is not included within the Pro Forma Consolidated  Condensed Statement
     of Operations. See Note 9 to the Unaudited Pro Forma Consolidated Condensed Balance Sheet for further information.

(2)  The Pro Forma Consolidated  Condensed  Statement of Operations assumes that SCCL and UK OpCo were sold by Calpine on January 1,
     2002. The results of SCCL and UK OpCo have been removed from the Pro Forma Consolidated Condensed Statement of Operations.  The
     estimated  non-recurring gain associated with the sales transaction is not included within the Pro Forma Consolidated Condensed
     Statement of Operations. See Note 13 to the Unaudited Pro Forma Consolidated Condensed Balance Sheet for further information.

(3)  Adjustment represents activity that was reclassified to discontinued operations as a result of the sale of the Domestic Oil and
     Gas Properties or SCCL and UK OpCo.

(4)  The Pro Forma  adjustments in the Unaudited Pro Forma  Consolidated  Condensed  Statement of Operations  include certain sales,
     general and  administrative  expenses  allocated  to Oil and Gas and to SCCL and UK OpCo based on a  proportion  of base wages.
     Accordingly,  these expenses have been included within the Oil and Gas and the SCCL and UK OpCo income figures to determine the
     Pro Forma totals.  For the year ended December 31, 2002,  these expenses  totaled $3.8 million and $2.0 million for Oil and Gas
     and for SCCL and UK OpCo, respectively.

(5)  The Pro Forma  adjustments also include  interest  expense that we expect to allocate to discontinued  operations in accordance
     with Emerging Issues Task Force ("EITF") Issue No. 87-24,  "Allocation of Interest to Discontinued Operations" ("EITF Issue No.
     87-24").  We  include  interest  expense  on debt  which is  required  to be repaid as a result of a  disposal  transaction  in
     discontinued  operations.  Additionally,  other  interest  expense that cannot be attributed to other  operations of Calpine is
     allocated  based on the  ratio of net  assets to be sold less  debt  that is  required  to be paid as a result of the  disposal
     transaction  to the sum of total net  assets of  Calpine  plus the  consolidated  debt of  Calpine,  excluding  (a) debt of the
     discontinued  operation  that  will be  assumed  by the  buyer,  (b) known  debt that will be paid as a result of the  disposal
     transaction and (c) debt that can be directly attributed to other operations of Calpine.  For the year ended December 31, 2002,
     the interest expense allocated within the Unaudited Pro Forma  Consolidated  Condensed  Statement of Operations is $3.5 million

               Calpine Completes Sale of Its Saltend Energy Centre

     (SAN JOSE,  Calif.)  /PR  Newswire - First  Call/ July 28, 2005 - A Calpine
Corporation  [NYSE:CPN]  subsidiary has completed the sale of its 1,200-megawatt
Saltend Energy Centre in Hull,  England for a total purchase price of (pound)490
million, or approximately  $US848 million,  plus adjustments for working capital
of $US14.5 million. The transaction, which has generated total gross proceeds to
Calpine of $US862.5 million (subject to post-closing adjustment), is part of the
company's  strategic  program  to  reduce  debt and  optimize  its  power  plant
portfolio.

     Calpine has sold the  natural  gas-fired  Saltend  power plant to a company
indirectly  owned by  International  Power plc and  Mitsui & Co.,  Ltd.  Calpine
acquired the plant in August 2001 for the sterling  equivalent of  approximately
$810 million.  With the completion of this  transaction,  Calpine no longer owns
any interest in Saltend.

     "The sale of Saltend has allowed Calpine to capture  significant  value for
our investment,"  said Calpine Chief Financial  Officer Bob Kelly. "The proceeds
from this sale will allow  Calpine to reduce  debt and focus our  efforts on the
North American power market."

     The two existing  series of  Redeemable  Preferred  Shares  relating to the
Saltend  Energy Centre were redeemed in connection  with the sale. The remaining
net proceeds are being held under the control of  Calpine's  subsidiary  Calpine
Canada Resources Company pursuant to an interim order issued yesterday,  pending
final  decision,  by the Supreme Court of Nova Scotia in the current  litigation
commenced in May by Harbert  Distressed  Investment  Master Fund, Ltd. The final
decision of that Court is expected within the next week.

     Calpine  Corporation  is  a  North  American  power  company  dedicated  to
providing electric power to customers from clean,  efficient,  natural gas-fired
and geothermal  power plants.  The company  generates power at plants it owns or
leases in 21 states in the United  States  and three  provinces  in Canada.  The
company is included in the S&P 500.  Calpine was founded in 1984 and is publicly
traded  on  the  New  York  Stock  Exchange  under  the  symbol  CPN.  For  more
