EXHIBIT 4.5

First Supplemental Indenture (this “Supplemental Indenture”), dated as of April 26, 2011, among each of New Development Holdings, LLC, Calpine Mid-Atlantic Energy, LLC, Calpine Mid-Atlantic Operating, LLC, Calpine Bethlehem, LLC, Calpine New Jersey Generation, LLC, Calpine Mid-Atlantic Generation, LLC, Calpine Solar, LLC, Calpine Vineland Solar, LLC and Calpine Mid-Atlantic Marketing, LLC (collectively, the “Guaranteeing Subsidiaries”), each a subsidiary of Calpine Corporation, a Delaware corporation (the “Company”), the Company, each of the guarantors party to the Indenture (as defined below) (the “Existing Guarantors”) and Wilmington Trust Company, as trustee under the Indenture referred to below (the “Trustee”).
W I T N E S S E T H
WHEREAS, the Company and each of the Existing Guarantors have heretofore executed and delivered to the Trustee an indenture (the “Indenture”), dated as of October 22, 2010, providing for the issuance of 7.50% Senior Secured Notes due 2021 (the “Notes”);
WHEREAS, the Indenture provides that under certain circumstances the Guaranteeing Subsidiaries shall execute and deliver to the Trustee a supplemental indenture pursuant to which each of the Guaranteeing Subsidiaries shall agree to guarantee all of the Company’s Obligations under the Notes and the Indenture on the terms and conditions set forth herein (the “Note Guarantee”); and
WHEREAS, pursuant to Section 9.01 of the Indenture, the Trustee is authorized to execute and deliver this Supplemental Indenture.
NOW, THEREFORE, in consideration of the foregoing and for other good and valuable consideration, the receipt of which is hereby acknowledged, each of the Guaranteeing Subsidiaries and the Trustee mutually covenant and agree for the equal and ratable benefit of the Holders as follows:
1. Capitalized Terms. Capitalized terms used herein without definition shall have the meanings assigned to them in the Indenture.
2. Agreement to Guarantee. Each of the Guaranteeing Subsidiaries hereby agrees to become subject to the Guarantee and Collateral Agreement pursuant to Section 4.13 of the Indenture.
3. No Recourse Against Others. No past, present or future director, officer, employee, incorporator, stockholder or agent of any of the Guaranteeing Subsidiaries, as such, shall have any liability for any obligations of the Company, any of the Existing Guarantors or any of the Guaranteeing Subsidiaries under the Notes, any Note Guarantees, the Indenture or this Supplemental Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes. Such waiver may not be effective to waive liabilities under the federal securities laws and it is the view of the Commission that such a waiver is against public policy.

5. Counterparts. The parties may sign any number of copies of this Supplemental Indenture. Each signed copy shall be an original, but all of them together represent the same agreement.
6. Effect of Headings. The Section headings herein are for convenience only and shall not affect the construction hereof.
7. The Trustee. The Trustee shall not be responsible in any manner whatsoever for or in respect of the validity or sufficiency of this Supplemental Indenture or for or in respect of the recitals contained herein, all of which recitals are made solely by each of the Guaranteeing Subsidiaries, the Company and the Existing Guarantors.
