(c, e)  On June 30, 2008, the Board of Directors of Calpine Corporation (the “Company”) approved the terms of certain compensation arrangements with Zamir Rauf in connection with his services as Interim Chief Financial Officer.  Mr. Rauf was appointed Interim Chief Financial Officer effective June 4, 2008, as reported in the Company’s Current Report on Form 8-K filed on June 5, 2008.

The compensation arrangements, as set forth in a letter agreement and related addendum, each dated June 30, 2008 (collectively, “the Letter Agreement”), are effective from June 4, 2008, through December 7, 2008. Pursuant to the terms of the Letter Agreement, Mr. Rauf will receive a base salary to be paid bi-weekly of $10,653.85 (annualized to $277,000) and a supplemental salary to be paid bi-weekly of $5,692.31 (annualized to $148,000). Mr. Rauf will remain eligible to participate in the Calpine Corporation 2007 Calpine Incentive Plan (the “CIP”), which provides for an annual discretionary bonus based on corporate, departmental and individual performance, with Mr. Rauf’s target bonus under the CIP to be 90% of his base pay and supplemental wages actually earned in 2008. The amount of the bonus, if any, awarded to Mr. Rauf under the CIP is subject to the Company’s discretion.  In addition, during the term of the Letter Agreement, Mr. Rauf will be a “Tier 3 Participant” under the Calpine Corporation Change in Control and Severance Benefits Plan, which provides for certain benefits in the event of a change in control or termination of the employee’s services under certain circumstances.

A copy of the Letter Agreement is filed herewith as Exhibit 10.1.
