                              EMPLOYMENT AGREEMENT



          This Employment  Agreement (the "Agreement") is entered into effective
as of January 1, 2005, between CALPINE CORPORATION,  a Delaware Corporation (the
"Company"),  and PETER  CARTWRIGHT  ("Mr.  Cartwright") to provide the terms and
conditions for Mr. Cartwright's employment.

          Mr. Cartwright has served as the President and Chief Executive Officer
of the Company since its inception in 1984 and has served as the Chairman of the
Board of  Directors of the Company  (the  "Board")  since  September  1996.  Mr.
Cartwright's current employment agreement expires on December 31, 2004.

          The Company and Mr.  Cartwright  have agreed that Mr.  Cartwright will
remain  employed  by the Company  and will  continue  to serve as the  Company's
President and Chief Executive Officer,  under the terms and conditions set forth
below.

          Accordingly,  and in consideration of the mutual obligations set forth
in this  Agreement,  which Mr.  Cartwright and the Company agree are sufficient,
Mr. Cartwright and the Company agree as follows:

     1.   Term of Employment.  Mr. Cartwright's  Term of  Employment consists of
the initial term  and any  subsequent  term for which the  Agreement is renewed.
The  initial  term of  this  Agreement  begins  on January 1, 2005,  and ends on
December 31, 2006.  Mr.  Cartwright  and  the  Company  may  agree  to renew the
Agreement for one or more of three successive one-year terms, as follows:

          a. On or before  June 30,  2006,  Mr.  Cartwright  and the Board shall
     decide  whether to renew the Agreement  for the first  renewal term,  which
     would begin on January 1, 2007, and end on December 31, 2007.

          b. If the  Agreement  is  renewed  for the  first  renewal  term,  Mr.
     Cartwright  and the Board shall decide on or before June 30, 2007,  whether
     to renew the  Agreement  for a second  renewal  term,  which would begin on
     January 1, 2008, and end on December 31, 2008.

          c. If the  Agreement  is renewed  for the  second  renewal  term,  Mr.
     Cartwright  and the Board shall decide on or before June 30, 2008,  whether
     to renew the  Agreement  for a third  renewal  term,  which  would begin on
     January 1, 2009, and end on December 31, 2009.

          d. If the  Agreement  is  renewed  for the  third  renewal  term,  Mr.
     Cartwright's  Term of Employment shall end on December 31, 2009, unless the
     Board  and  Mr.  Cartwright  agree  to an  extension  of  Mr.  Cartwright's
     employment with the Company.

          If Mr.  Cartwright  and the Board  decide on or before  June 30 of the
year  preceding  any renewal  term not to renew the  Agreement  for such renewal
term,  Mr.  Cartwright's  Term of  Employment  shall end when the  current  term
expires.

          If Mr. Cartwright's Agreement is not renewed for the first, second, or
third renewal term,  Mr.  Cartwright  shall continue to be available to serve as
Chairman of the Board if he continues to be nominated  and elected as such,  and
shall provide  consulting and advisory  services to the Company and to the Board
to the  extent  requested  by the  Company or the  Board,  in each case  through
December 31, 2009. Mr.  Cartwright shall be entitled to reasonable  compensation
for such services,  as shall be mutually  agreed between Mr.  Cartwright and the
Board. Mr.  Cartwright's  undertaking to provide continued services to the Board
or the  Company  under this  paragraph  shall  apply only to the extent that the
undertaking  does not make it  necessary  to delay the payment of any  severance
benefit to which he is entitled  under  paragraph 4, in order to comply with the
distribution  restrictions imposed by Section 409A of the Internal Revenue Code.
During any period in which Mr.  Cartwright  is  obligated  to provide  continued
services to the Company or the Board, Mr.  Cartwright shall not provide services
to any competitor of the Company.

          The Board may terminate Mr.  Cartwright's  employment for Cause at any
time  after  providing  Mr.  Cartwright  with 10 days'  advance  written  notice
explaining the circumstances that justify the termination.  "Cause" means any of
the following:  (1) material  breach of any material term of this Agreement that
is not  corrected  within  10 days  after  the  Board's  written  notice  to Mr.
Cartwright of the breach; (2) conviction of a felony;  (3) repeated  unexplained
or  unjustified  absence;  (4)  willful  breach of  fiduciary  duty  under  this
Agreement;  or (5)  gross  negligence  or  willful  misconduct,  where the gross
negligence  or willful  misconduct  has  resulted,  or is likely to  result,  in
substantial and material damage to the Company or any of its subsidiaries.

          Mr.  Cartwright  may terminate his  employment  for Good Reason at any
time.  "Good Reason" means the material  breach by the Company of one or more of
its material  obligations  under this Agreement that is not corrected  within 10
days after Mr. Cartwright's written notice to the Company of the breach.

Cartwright  shall  have the  position  and  responsibilities  described  in this
paragraph  2. Mr.  Cartwright  shall  serve  as the  Company's  Chief  Executive

     date the option is granted, and shall vest upon the earlier of:

               1) the stock price  closing at or above  $10.00 per share (or the

               reverse stock split, stock dividend, recapitalization, or similar
               change  affecting  the  Company's  outstanding  common stock as a
               class without the Company's  receipt of  consideration)  for four
               consecutive trading days, or

               2) December 31, 2009.

               Except as  provided  below in the case of  Disability  (paragraph
     3.h), death (paragraph 3.i), or severance  (paragraph 4.c), Mr.  Cartwright
     shall forfeit the option if he ceases to be employed as the Company's Chief
     Executive Officer before the option vests.

          h. Disability Benefits. If Mr. Cartwright becomes Disabled (as defined
     below)  while he is an active  employee of the Company,  the Company  shall
     continue to pay his Base Salary until his employment terminates as provided
     in the next sentence;  and the Company shall also pay Mr.  Cartwright a pro
     rata  portion of his annual  Target  Bonus for the portion of the  calendar
     year  before his  Disability.  If Mr.  Cartwright  remains  Disabled  for a
     continuous period exceeding six calendar months,  the Company may terminate
     his employment at any time after the end of the six-month  period, in which
     case Mr. Cartwright shall be eligible for any long-term disability benefits
     provided under the Company's  employee  benefit plans;  for full vesting of
     any  unvested  option  described  in  paragraph  3.g,  above;  and  for the
     severance benefits described in paragraph 4, below.

               For  purposes  of  this  Agreement,   Mr.   Cartwright  shall  be
     "Disabled"  if he is  unable  to  perform  all the  material  duties of his
     position, as determined by an independent physician approved by the Company
     and Mr.  Cartwright;  and "Disability" shall mean a period during which Mr.
     Cartwright remains Disabled.

          i.  Death  Benefits.  Subject to its terms,  Mr.  Cartwright  shall be

     Mr.  Cartwright  dies while he is employed  by the  Company,  any  unvested
     option described in paragraph 3.g, above,  shall become fully vested at the
     time of his death,  and the option may be exercised by his  beneficiary  or
     personal  representative  at any time during its remaining term. Unless Mr.
     Cartwright   has  executed  a  valid  written   instrument   designating  a
     beneficiary  or  beneficiaries  to receive any benefit  payable  under this
     Agreement in the event of his death,  his beneficiary  under this Agreement
     shall be deemed to be the same as his beneficiary under the Company's group
     life insurance program.


                                     Page 4


     4.   Severance. Mr.Cartwright shall receive the severance benefit described
in this paragraph 4 if the Company terminates Mr. Cartwright's employment at any
time during the Term of Employment  or if this  Agreement is not renewed for the
first, second, or third renewal term (and the termination or failure to renew is
not for Cause), or if Mr. Cartwright resigns for Good Reason.

          a. Amount and Payment  Schedule.  Mr.  Cartwright's  severance benefit
     shall be an annual  amount  equal to the sum of his annual  Base Salary and
     Target Bonus as of the date his employment terminates, paid for the shorter
     of (i) two years or (ii) the period from his  termination  date to December
     31, 2009. For purposes of this paragraph, Mr. Cartwright's employment shall
     be deemed to have  terminated at the end of his Term of Employment  even if
     he remains obligated to provide continued services as Chairman of the Board
     or continued  consulting and advisory  services as provided in paragraph 1.
     Subject to the timing rule  described  in  paragraph  4.b,  below,  and the
     special  rule in case of death  described  in  paragraph  4.d,  below,  the
     severance  benefit shall be paid ratably on the same payment  schedule that
     applied to Mr. Cartwright's salary at the time of his termination.

          b. Timing.  To the extent  necessary to comply with the restriction in
     Section  409A(a)(2)(B) of the Internal Revenue Code concerning  payments to
     specified employees, the first severance payment to Mr. Cartwright shall be
     made on the first  installment date (determined under paragraph 4.a, above)
     that is at least six months after Mr.  Cartwright's  termination  date. The
     first  payment  shall  include any  installments  that would have been paid
     previously  under  paragraph 4.a were it not for this special  timing rule,
     plus  interest on the delayed  installments  at an annual rate  (compounded
     monthly) equal to the federal  short-term  rate (as in effect under Section
     1274(d) of the Internal Revenue Code on his termination date).

          c. Other Severance Benefits.  If Mr. Cartwright is entitled to receive
     a severance benefit under paragraph 4.a as a result of his termination,  he
     shall also receive the following benefits:

               1.   All stock options,  restricted stock, warrants,  rights, and
                    other equity awards  granted by the Company  (including  the
                    option  described  in  paragraph  3.g) shall vest and remain
                    exercisable through their initial terms.

               2.   Until  December 31, 2009, the Company shall at its sole cost
                    and expense (but  disregarding  any individual tax liability
                    of Mr.  Cartwright)  provide Mr.  Cartwright (and his spouse
                    and eligible  dependents)  with life  insurance,  disability
                    insurance,  group health  benefits,  and accidental death or
                    dismemberment   benefits   substantially  similar  to  those
                    benefits  that Mr.  Cartwright  (and his spouse and eligible
                    dependents)   were   receiving    immediately   before   his
                    termination.  If Mr. Cartwright (or his spouse or dependent)
                    elects to receive  health care  continuation  coverage under
                    Section 4980B of the Internal  Revenue  Code,  that coverage
                    shall be in lieu  of,  and not in  addition  to,  the  group
                    health coverage described in this subparagraph.


                                     Page 5


               3.   If  all  or  any  portion  of  the  amounts  payable  to Mr.
                    Cartwright  under this Agreement or otherwise are subject to
                    the golden  parachute  excise tax imposed by Section 4999 of
                    the Internal Revenue Code (or any similar tax under state or
                    local law),  the Company shall pay Mr.  Cartwright an amount
                    necessary  to place  Mr.  Cartwright  in the same  after-tax
                    position  that  Mr.  Cartwright  would  have  been in if the
                    excise  tax  had  not  been  imposed.   The  amount  of  the
                    additional  payment  shall be  determined  by the  Company's
                    independent accountants.

          d.  No  Severance  After  Death.  If Mr.  Cartwright  qualifies  for a
     severance benefit under paragraph 4.a but he dies before the last severance
     payment is made, any remaining severance payments under paragraph 4.a shall
     be  canceled  and his  beneficiary  (or  beneficiaries)  shall  receive any
     benefit payable under paragraph 3.i.

          e. No  Severance  Benefit  for  Termination  for  Cause  or  Voluntary
     Termination.  If the Company  terminates  Mr.  Cartwright's  employment for
     Cause,  or if Mr.  Cartwright  resigns (and his resignation is not for Good
     Reason),  Mr.  Cartwright  shall not be eligible  to receive any  severance
     benefit under this paragraph 4. Mr.  Cartwright's  eligibility  (if any) to
     receive a severance  or  retirement  benefit  under any other  severance or
     retirement plan or program maintained by the Company shall be determined by
     the terms of that plan or program as in effect on his termination date.

     5.   Employment  Taxes.  All payments  and other  compensation  under  this
Agreement  shall  be  subject  to  withholding  of  the  applicable  income  and
employment  taxes.  At  the  same  time,  however,   Mr.  Cartwright  is  solely
responsible for paying all required taxes on any payments or other  compensation
provided under this Agreement  (including imputed  compensation),  regardless of
whether taxes are withheld.

     6.   Nonduplication  of Benefits.  No  term  or  other  provision  of  this
Agreement may be interpreted to require the Company to duplicate  any payment or
other compensation that Mr. Cartwright is already entitled  to  receive  under a
compensation or benefit plan,  program,  or other arrangement  maintained by the
Company.

     7.   Indemnification.  To  the  extent  permitted  by  applicable  law, the
Companyshall provide indemnification for Mr. Cartwright under  its  Articles  of
Incorporation  and  Bylaws.  Mr.  Cartwright  shall be covered by the  Company's
standard indemnification agreement and by any director's and officer's liability
insurance policy maintained by the Company.

     8.   Successors.  Any  successor  to the Company or to all or substantially
all  of  the Company's  business  and/or  assets  (whether  a direct or indirect
successor, and whether by purchase, lease, merger,  consolidation,  liquidation,
or otherwise) shall assume the obligations under this Agreement.  In case of any
succession,  the term "Company" shall refer to the successor.  The terms of this
Agreement  and all of Mr.  Cartwright's  rights  hereunder  shall  inureto the
benefit  of,  and  be  enforceable  by,  Mr.  Cartwright's   personal  or  legal
representatives,  executors,  administrators,  successors,  heirs, distributees,
devisees, and legatees.

above,  nothing  in  this  Agreement  may confer upon any person or entity not a
party  to this Agreement any rights or remedies of any nature or kind whatsoever
under or by reason of this Agreement.

     10.  No Duty to Mitigate.  Mr. Cartwright shall not be required to seek new

          a.  Notices  and  other  communications  to Mr.  Cartwright  shall  be
     addressed  to Mr.  Cartwright,  at the most  recent  home  address  that he
     provided in writing to the Company.

          b. Notices and other  communications to the Company shall be addressed
     to the Company's corporate headquarters,  to the attention of the Company's

waived, or discharged,  unless the modification,  waiver, or discharge is agreed
to in writing signed by Mr.  Cartwright and by an authorized  representative  of
the Company (other than Mr. Cartwright).  Unless specifically characterized as a
continuing  waiver, no waiver of a condition or provision at any one time may be
considered  a waiver  of the  same  provision  or  condition  (or any  different
provision or condition) at any other time.

     13.  Agreement to Arbitrate. Any dispute arising out of or relating to this
Agreement,  or  otherwise  arising  out  of  or  relating  to  Mr.  Cartwright's
employment  with the  Company,  may be settled by  arbitration  in the County of

then in effect. Any arbitration proceedings shall be non-binding: any claim with
respect to this Agreement,  whether or not previously arbitrated, may be brought
in any court of competent jurisdiction.

     14.  Choice of Law. This Agreement (including its validity, interpretation,
construction,  and  performance)  shall be  governed by the laws of the State of
California,  without  regard to any rule or  principle  concerning  conflicts or
choice of law that might otherwise refer  construction or  interpretation to the
substantive law of another jurisdiction.

     16.  Severability  and  Reformation.  Each  substantive  provision  of this

consideration, and is severable from the other provisions of the Agreement. If a
court of competent  jurisdiction  determines  that any term or provision of this
Agreement  is  unenforceable,  then  the  other  terms  and  provisions  of this

provisions  shall be equitably  modified to the extent  necessary to achieve the
underlying purpose in an enforceable way.

     17.  Whole Agreement. This Agreement reflects the entire  understanding and
agreement  between the Company and Mr.  Cartwright  regarding  Mr.  Cartwright's
employment.  This  Agreement  supersedes  all prior  negotiations,  discussions,
correspondence,   communications,   understandings,  and  agreements  (including
without  limitation  the  employment  agreement  between  the  Company  and  Mr.
Cartwright that was entered into effective as of January 1, 2000),  whether oral
or written,  relating  to Mr.  Cartwright's  employment  with the  Company.  The
respective rights and obligations of the parties to this Agreement shall survive
the termination of Mr.  Cartwright's  employment to the extent necessary to give
such rights and obligations their intended effect.

     18.  Counterparts. This Agreement may be executed in counterparts,  each of
which shall be deemed an original,  but all of which together shall constitute a
single instrument.

                                      * * *


          IN WITNESS  WHEREOF,  the parties to this Agreement have executed this
Agreement on March 9, 2005.
