$1.4 Billion Available Under Unsecured Working Capital Facilities

SAN JOSE, Calif., Jan. 10 /PRNewswire-FirstCall/ -- San Jose, Calif.-based Calpine Corporation (NYSE: CPN) today announced that it has received commitment letters from its lenders for an additional $1 billion unsecured working capital credit facility. This new one-year facility will enable Calpine to borrow up to $350 million and will provide Calpine with up to $1 billion of letter of credit capacity. Calpine expects to close the new facility by the end of January.

Added to the company's existing $400 million unsecured working capital credit facility, which expires on May 24, 2003, Calpine will have access to up to $750 million in borrowing capacity and up to $1.4 billion of letter of credit capacity.

Bob Kelly, president of Calpine Finance Company, said, "This additional $1 billion unsecured working capital credit facility is a strong vote of confidence from our commercial bank lenders. Including our revolving construction credit facilities, we now have $4.9 billion of bank financing in place."
