ITEM 1.01 ENTRY INTO A MATERIAL  DEFINITIVE  AGREEMENT



Chairman, President and Chief Executive Officer Employment Agreement


     On March  9,  2005,  the  Board  of  Directors  (the  "Board")  of  Calpine
Corporation  (the  "Issuer")   approved  an  employment   agreement  with  Peter
Cartwright  to serve as the Issuer's  Chairman,  President  and Chief  Executive
Officer. The agreement, attached as Exhibit 10.1 hereto, is made effective as of
January 1, 2005, and includes the following provisions:

1.   The term of the  agreement  is two years  (until  December 31, 2006) and is
     renewable for three successive  one-year terms upon the mutual agreement of
     the Board and Mr. Cartwright.

2.   Mr.  Cartwright  will  receive a minimum  base  salary  of  $1,000,000,  as
     adjusted  annually  by  the  Compensation   Committee  and  Nominating  and
     Governance  Committee of the Board, acting jointly (the "Joint Committee"),
     and shall be eligible to receive an annual  performance bonus as determined
     by the Joint Committee.  Mr.  Cartwright's target bonus is 180% of his base
     salary.

3.   Upon signing the  agreement,  Mr.  Cartwright  will be granted an option to
     purchase  1,250,000  shares of common stock  pursuant to the  Discretionary
     Option Grant Program of the Issuer's 1996 Stock Incentive Plan, as amended.
     Such option was granted on March 9, 2005 at an exercise  price of $3.80 per
     share (representing the closing price of Calpine common stock on January 3,
     2005). The option has a six-year term and will vest upon the earlier of (i)
     the Company's common stock closing price equaling at least $10.00 per share
     for four consecutive  trading days and (ii) December 31, 2009. A filing for
     such equity award was made with the Securities  and Exchange  Commission on
     Form 4 on March 10, 2005.

4.   Mr. Cartwright shall continue to serve as Chairman of the Board for as long
     as he continues to be nominated and elected.

5.   Mr.  Cartwright is entitled to certain  severance  benefits as set forth in
     the agreement in the event that (i) Mr. Cartwright  resigns for good cause,
     (ii) the Company  terminates his  employment  other than for cause or (iii)
     the agreement is not renewed for any of the three  one-year  renewal terms.
     The  severance  benefits  include an annual  amount equal to the sum of Mr.
     Cartwright's base salary and target bonus at the time of the termination of
     his  employment,  paid for the shorter of (i) two years and (ii) the period
     from his termination date to December 31, 2009.

6.   Disputes under the agreement will be resolved by arbitration.
