1. The subscription terms set forth herein (the “Subscription”) are made as of the date set forth below between Capstone Turbine Corporation, a Delaware corporation (the “Company”), and the Investor.

2. As of the Closing (as defined below) and subject to the terms and conditions hereof, the Company and the Investor agree that the Investor will purchase from the Company and the Company will issue and sell to the Investor (i) such number of shares (the “Shares”) of common stock, par value $0.001 per share, of the Company (the “Common Stock”), and (ii) such number of Warrants to purchase Common Stock (the “Warrants” in the form attached hereto as Exhibit B, and together with the Shares, the “Securities”) as is set forth on the signature page hereto (the “Signature Page”) for a purchase price of $1.14 per unit. The Investor acknowledges that the offering is not a firm commitment underwriting and that there is no minimum offering amount.

3. The completion of the purchase and sale of the Securities shall occur at a closing (the “Closing”) that, in accordance with Rule 15c6-1 promulgated under the Securities Exchange Act of 1934, as amended, is expected to occur on or about January 24, 2007. At the Closing, (a) the Company shall cause its transfer agent to release to the Investor the number of Securities being purchased by the Investor and (b) the aggregate purchase price for the Securities being purchased by the Investor will be delivered by or on behalf of the Investor to the Company. The Investor shall settle the Shares via Deposit/Withdrawal At Custodian (“DWAC”) and the provisions set forth in Exhibit A hereto shall be incorporated herein by reference as if set forth fully herein.

4. The offering and sale of the Securities are being made pursuant to the Registration Statement and the Prospectus (as such terms are defined below). The Investor acknowledges that the Company intends to enter into subscriptions in substantially the same form as this Subscription with certain other investors and intends to offer and sell (the “Offering”) up to an aggregate of 40,000,000 shares of Common Stock and Warrants to purchase 20,000,000 shares of Common Stock pursuant to the Registration Statement and Prospectus. The Investor acknowledges and agrees that there is no minimum offering amount.

5. The Company has filed with the Securities and Exchange Commission (the “Commission”) a prospectus (the “Base Prospectus”) and will promptly file a final prospectus supplement (collectively, the “Prospectus”) with respect to the registration statement (File No. 333-128164) reflecting the Offering, including all amendments thereto, the exhibits and any schedules thereto, the documents otherwise deemed to be a part thereof or included therein by the rules and regulations of the Commission (the “Rules and Regulations”) and any registration statement relating to the Offering and filed pursuant to Rule 462(b) under the Rules and Regulations (collectively, the “Registration Statement”), in conformity with the Securities Act of 1933, as amended (the “Securities Act”), including Rule 424(b) thereunder. The Investor hereby confirms that it has had full access to the Base Prospectus and the Company’s periodic reports and other information incorporated by reference therein, and was able to read, review, download and print such materials.

(the “Placement Agent”), which will act as the Company’s placement agent with respect to the Offering and receive a fee in connection with the sale of the Securities. The Placement Agreement contains certain representations and warranties of the Company. The Company acknowledges and agrees that the Investor may rely on the representations and warranties made by it to the Placement Agent in Section 3 of the Placement Agreement, to the same extent as if such representations and warranties had been incorporated in full herein and made directly to the Investor. Capitalized terms used, but not otherwise defined, herein shall have the meanings ascribed to such terms in the Placement Agreement.
