Re.   Employment Separation

Dear Calpine Employee:

Your employment with Calpine will end effective February 27, 2007 as a result of a reduction in workforce or restructuring activities (“Qualifying Event”). This letter agreement (the “Agreement”) confirms the terms of your separation from employment with Calpine Corporation, a Delaware corporation or one or more of its subsidiaries (collectively, “Calpine”) and offers you the following benefits in exchange for a release of all claims.

1. Separation Date. Your employment with Calpine will be terminated effective February 27, 2007 (the “Separation Date”).

2. Additional Payment and Benefits. In exchange for the waiver and release described in Paragraphs 7 and 8 below, Calpine agrees to provide you with an additional payment and benefits as described in the Calpine Corporation U.S. Severance Program and the Severance Benefit Summary Sheet provided to you with this letter. By signing this Agreement, you also warrant that you understand and have read the terms of the Calpine Corporation U.S. Severance Program.

3. Participation in Stock/401(k) and Life and Disability Insurance Plans. As you will no longer be a Calpine employee after the Separation Date, you will not participate in Calpine’s Employee Stock Purchase Plan and life and disability insurance plans after the Separation Date. Distribution options under Calpine’s 401(k) plan will be pursuant to the plan rules, and you will be provided with notice of such options by separate letter.

4. Return of Company Property. You warrant that, by the Separation Date, you will return to your manager or human resources representative all Calpine property or data of any type, including computer and e-mail passwords, that are in your possession or control, without retaining any copies, notes or extracts thereof.

5. References. You should direct all requests for employment references to Xxxxx Xxxxxxxx in Calpine’s Human Resources Department, xxxxxx@xxxxxxx.xxx, or her successor. Human Resources will respond to all such inquiries by stating that, as a matter of company policy, Calpine declines to provide any information regarding former employees other than the former employee’s dates of employment and job title, and with written authorization from the employee, the former employee’s salary.

6. Confidential Information; Use of Confidential Information to Compete. By signing below, you acknowledge that as a result of your employment with Calpine you have had access to Confidential Information of Calpine (for the purposes of this

February 27, 2007 Page 2

Agreement, Confidential Information includes but is not limited to trade secrets, inventions, marketing plans, product plans, business strategies, financial information, forecasts, personnel information, customer lists, customer information, and any other information which gives Calpine an opportunity to obtain advantage over competitors who do not know or use it) and that you will hold all such Confidential Information in strictest confidence and will not disclose to any person or entity or make use, directly or indirectly, of such Confidential Information. You confirm that you will deliver to your manager or human resources representative, within ten (10) days of the Separation Date, all diskettes, documents and data of any nature pertaining to any such Confidential Information and that you have not taken or retained any such diskettes, documents or data or any reproductions. Nor shall you directly or indirectly use Confidential Information of Calpine to compete with Calpine, or disclose Confidential Information to a competitor of Calpine or to any other person or entity.

7. Release of Claims. You acknowledge that you have no claims against Calpine based on your employment with Calpine or the separation of that employment, except for claims asserted as of February 1, 2006 in Xxxxxx X. Xxxxxx, Xx., et al. v. Calpine Corporation, et al., Case No. 1-04-CV-032103 (CA Superior Court, Santa Xxxxx County), if you are a class member identified in that lawsuit, and except for other claims that are specifically excluded from this release by Paragraph 8, below. By signing below, you release Calpine and forever discharge Calpine from all claims, demands, causes of action, damages and liabilities, known or unknown, that you have ever had, now have or may claim to have had relating to or arising from your employment with or separation from Calpine, except for claims that are specifically excluded from this release by Paragraph 8, below.

You expressly waive the benefits of Section 1542 of the Civil Code of the State of California (and under other state and federal provisions of similar effect) which provides:

A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE CREDITOR DOES NOT KNOW OR SUSPECT TO EXIST IN HIS OR HER FAVOR AT THE TIME OF EXECUTING THE RELEASE, WHICH IF KNOWN BY HIM OR HER MUST HAVE MATERIALLY AFFECTED HIS OR HER SETTLEMENT WITH THE DEBTOR.

8. Waiver of Claims Including Employment-Related Claims. You understand that the release you are providing releases and waives any and all claims you may have against Calpine and its owners, agents, officers, shareholders, employees, directors, attorneys, subscribers, subsidiaries, affiliates, insurers, successors and assigns, whether known or not known, including, without limitation, claims under any employment laws, including, but not limited to, claims of unlawful discharge, breach of contract, breach of the covenant of good faith and fair dealing, retaliation, harassment, fraud, violation of public policy, defamation, physical injury, emotional distress, claims for compensation or benefits arising out of your employment or your separation of employment, claims
