ITEM 1.01 — ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT

On May 25, 2010, as further discussed in Item 2.03 below, Calpine Corporation (“Calpine”) closed on its offering of $400 million in aggregate principal amount of its 8% Senior Secured Notes due 2019 (the “Notes”) in a private placement. The Notes were issued under an amended and restated indenture, dated as of May 25, 2010 (the “Indenture”), among Calpine, the guarantors party thereto and Wilmington Trust Company, as trustee. The Notes, and related guarantees, are secured equally and ratably with the indebtedness incurred under Calpine’s First Lien Credit Facility by a first-priority lien on substantially all of Calpine’s and certain of the guarantors’ existing and future assets, subject to certain exceptions and permitted liens. The net proceeds from the offering of the Notes were used to repay a portion of the term loan borrowings under Calpine’s First Lien Credit Facility. Such term loans were extinguished and may not be reborrowed. The information in Item 2.03 below is hereby incorporated by reference in this Item 1.01.

ITEM 2.03 — CREATION OF A DIRECT FINANCIAL OBLIGATION OR AN OBLIGATION UNDER AN OFF-BALANCE SHEET ARRANGEMENT OF A REGISTRANT

On May 25, 2010, Calpine issued $400 million in aggregate principal amount of its 8% senior secured notes due 2019 in a private placement. This summary of the terms of the Indenture and the Notes is qualified in its entirety by reference to the Indenture, a copy of which (including the form of the Notes) is attached as Exhibit 4.1 to this Current Report on Form 8-K and is incorporated by reference herein.

The Notes bear interest at 8% payable on February 15 and August 15 of each year beginning on August 15, 2010. Calpine will make each interest payment to the holders of record on the February 1 and August 1 immediately preceding the applicable interest payment date. The Notes will mature on August 15, 2019. The Notes are guaranteed by each of Calpine’s current and future domestic subsidiaries that are a borrower or guarantor under the First Lien Credit Facility and rank equally in right of payment with all of Calpine’s and the guarantors’ other existing and future senior indebtedness, and will be effectively subordinated in right of payment to all existing and future liabilities of Calpine's subsidiaries that do not guarantee the Notes. The Notes are secured equally and ratably with indebtedness under Calpine’s First Lien Credit Facility by a first-priority lien, subject to certain exceptions and permitted liens, on substantially all of Calpine’s and certain of the guarantors’ existing and future assets.

Subject to certain qualifications and exceptions, the Indenture will, among other things, limit Calpine’s ability and the ability of the guarantors to:

          •  incur or guarantee additional first lien indebtedness;

          •  enter into commodity hedge agreements;

          •  enter into sale and leaseback transactions;

          •  create liens; and

          •  consolidate, merge or transfer all or substantially all of Calpine’s assets and the assets of Calpine’s restricted subsidiaries on a combined basis.

On or after August 15, 2015, Calpine may on any one or more occasions redeem all or a part of the Notes, upon not less than 30 nor more than 60 days’ notice, at the redemption prices set forth in the Indenture, plus any accrued and unpaid

interest. Calpine may also redeem any of the Notes at any time prior to August 15, 2015, at a price equal to 100% of the aggregate principal amount thereof, plus a “make-whole” premium and accrued and unpaid interest. Prior to August 15, 2013, Calpine may redeem up to 35% of the aggregate principal amount of the Notes with the net cash proceeds of certain equity offerings, at a price equal to 108% of the aggregate principal amount thereof, plus accrued and unpaid interest. In addition, prior to August 15, 2015, but not more than once in any 12-month period, Calpine may redeem up to 10% of the original aggregate principal amount of the Notes at a redemption price of 103% of the aggregate principal amount thereof, plus accrued and unpaid interest.

If a Change of Control Triggering Event (as defined in the Indenture) occurs, each holder of the Notes will have the right to require Calpine to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of that holder’s Notes pursuant to a Change of Control Offer (as defined in the Indenture) on the terms set forth in the Indenture in cash equal to 101% of the aggregate principal amount, plus accrued and unpaid interest.

If an event of default arises from certain events of bankruptcy or insolvency, all outstanding Notes will become due and payable immediately without further action or notice. If other events of default arise, including failure to pay principal or interest on a timely basis, failure to comply with the agreements under the Indenture or related security documents, default under or acceleration of certain other indebtedness, failure to pay certain judgments, and repudiation or unenforceability of obligations under the security documents or the guarantees, subject to certain limitations including, if applicable, the giving of notice or the expiration of any grace or cure period, or both, the trustee or holders of at least 25% of the aggregate principal amount of the outstanding Notes may declare the Notes to be due and payable immediately.
