                               CONSULTING CONTRACT

         THIS CONSULTING CONTRACT ("Contract") is made and entered into
effective as January 1, 2004 (the "Effective Date") between Calpine Corporation,
a Delaware corporation, of 50 West San Fernando Street, San Jose, California
95113 ("CALPINE") and GEORGE J. STATHAKIS, 120 Montgomery Street, 13th Floor,
San Francisco, California 94104 ("CONSULTANT"), with reference to the following:

         In consideration of the mutual agreements herein contained, it is
agreed as follows:

1.       SCOPE OF SERVICES

         CONSULTANT agrees to provide advice and guidance on various management
         issues to the President and members of his senior staff.

2.       TERM

         2.0      This Contract shall be for a term lasting from the Effective
                  Date until December 31, 2004, unless earlier terminated
                  pursuant to this Contract or extended by mutual agreement of
                  the parties.

         2.1      Notwithstanding the above, either party may terminate this
                  Contract at any time by giving thirty (30) days written notice
                  to the other party, provided, however, that any payments due
                  and payable upon termination shall be paid.

3.       COMPENSATION

         Compensation to CONSULTANT for services rendered shall be as follows:

         (a)  CALPINE will pay CONSULTANT a monthly retainer (the "Retainer") of
              Five Thousand Dollars ($5,000.00), commencing January 1, 2004,
              which amount will be payable at the beginning of each month under
              the term hereof.

         (b)  In addition to the cash compensation stated in (a) above, CALPINE
              will grant to CONSULTANT stock options under the Discretionary
              Option Grant Program of the Calpine Corporation 1996 Stock
              Incentive Plan to purchase 10,000 shares. The grant will be
              effective January 1, 2004; the option price for this grant will be
              the fair market value of Calpine Corporation stock at the close of
              business on the effective date of the grant. The options will be
              vest in twelve monthly installments and have a ten year term.

         (c)  In addition to the above, CALPINE agrees to reimburse CONSULTANT
              for all travel and other actual out-of-pocket expenses incurred in
              support of this Contract. Such expenses will not be incurred by
              CONSULTANT without prior approval of CALPINE. CONSULTANT shall
              furnish copies of all receipts with invoices for expenses incurred
              in support of this Contract.

4.       WARRANTY

         CONSULTANT assumes professional and technical responsibility for
         performance of Services to be provided hereunder in accordance with
         recognized professional standards. If within one year following
         completion of the Services, the Services fail to meet the aforesaid
         standards, and CALPINE promptly advises CONSULTANT in writing,
         CONSULTANT agrees to re-perform deficient Services without charge to
         CALPINE up to a maximum amount equivalent to the compensation received
         for the deficient Services rendered.

5.       INDEPENDENT CONTRACTOR

         5.1      CONSULTANT acknowledges and agrees that it enters into this
                  Contract as an independent contractor. Under no circumstances
                  shall CONSULTANT look to CALPINE as its employer, nor as a
                  partner, agent or principal. CONSULTANT shall not be entitled
                  to any benefits accorded to CALPINE's employees including,
                  without limitation, workers compensation, disability
                  insurance, and vacation or sick pay. CONSULTANT shall be
                  responsible for providing, at its expense and in its name,
                  disability, workers' compensation or other insurance as well
                  as licenses and permits usual or necessary for conducting the
                  Services hereunder.

         5.2      CONSULTANT shall pay, when and as due, any and all taxes
                  incurred as a result of CONSULTANT's compensation hereunder,
                  including estimated taxes. CONSULTANT hereby indemnifies
                  CALPINE for any claims, lost costs, fees, liabilities, damages
                  or injuries suffered by CALPINE arising out of CONSULTANT's
                  breach of this section.

         5.3      CONSULTANT represents that he or she has the qualifications
                  and ability to perform the Services in a professional manner,
                  without the advice, control or supervision of CALPINE.
                  CONSULTANT shall be solely responsible for the professional
                  performance of the Services, and shall receive no assistance,
                  direction or control from CALPINE. CONSULTANT shall have sole
                  discretion and control of its work and the manner in which it
                  is performed.

6.       INSURANCE

         6.1      CONSULTANT shall maintain in full force and effect during the
                  term of this Contract, the insurance described below, as well
                  as such other insurance as deemed reasonably necessary by
                  CALPINE to insure the services performed hereunder.

                  6.1.1    Automobile liability insurance covering owned,
                           non-owned and hired automobiles for a combined single
                           limit of $100,000/$300,000 for bodily injury and
                           property damage.

         6.2      CONSULTANT shall, upon request, furnish certificates showing
                  that the above insurance will be in effect during the term of
                  this Contract and shall specify that CALPINE must be given, in
                  writing, thirty (30) days notice of cancellation, termination,
                  or alternation of the policies evidenced by certificates. It
                  is acknowledged, understood and agreed that no payment shall
                  be due from CALPINE under this Contract at any time when
                  CONSULTANT is not in full compliance with this provision
                  dealing with insurance.

7.       INDEMNITY

         7.1      CALPINE agrees to indemnify CONSULTANT and hold him harmless
                  against any claim by any person that CONSULTANT's performance
                  arising from or in connection with CONSULTANT's relationship
                  with CALPINE renders CONSULTANT liable to such person, and
                  against any losses or damages suffered by CALPINE and its
                  affiliates as a result of any such claim (including legal fees
                  and expenses); provided, however, that such indemnity will not
                  extend to any action taken or omitted by CONSULTANT as a
                  result of gross negligence or willful misconduct.

         7.2      CONSULTANT shall not be liable for any consequential or
                  indirect damages occurring as a result of any recommendation,
                  opinion or advice given by CONSULTANT, or from any
                  implementation of CONSULTANT's recommendations by CALPINE, or
                  from any other services performed hereunder by CONSULTANT for
                  CALPINE.

         subcontract any of the work without the prior written consent of
         CALPINE. CONSULTANT shall supervise all work subcontracted by
         CONSULTANT in performing the Services and shall be responsible for all
         work performed by a subcontractor as if CONSULTANT itself had performed
         such work. The assignment or subcontracting of any work to
         subcontractors shall not relieve CONSULTANT from any of its obligations
         under this Contract with respect to the Services.

9.       CONFIDENTIALITY

         All data, information, work papers, technology and reports furnished or
         disclosed by CALPINE to CONSULTANT or its personnel in the course of
         performing the Services ("Information") are and shall remain the sole
         property of CALPINE and shall be kept confidential by CONSULTANT, and
         shall be delivered over to CALPINE at CALPINE's request. CONSULTANT
         agrees not to divulge all or any part of the Information to third
         parties, without the prior written consent of CALPINE, unless:

         (a)      The Information is known to CONSULTANT prior to obtaining the
                  same from CALPINE;

         (b)      The Information is, at the time of disclosure by CONSULTANT,
                  then in the public domain; or

         (c)      The Information is obtained by CONSULTANT from a third party
                  who did not receive same, directly or indirectly, from CALPINE
                  and who has no obligation of secrecy with respect thereto.

         CONSULTANT further agrees that it will not, without the prior written
         consent of CALPINE, disclose to any third party any of such Information
         developed or obtained by CONSULTANT in the performance of this
         Contract. If so requested by CALPINE, CONSULTANT further agrees to
         require its employees to execute a nondisclosure agreement prior to
         performing Services under this Contract.

         public forum without obtaining prior written approval from CALPINE.

12.      SURVIVAL

         The rights and obligations of the parties, which, by their nature, are
         normally intended to survive the termination or completion of this
         Contract shall remain in full force and effect following termination of
         this Contract for any reason.
