( 2 )Under the merger agreement governing the Mergers (the "Merger Agreement"), Seller will receive additional shares of the Issuer if certain targets are met with respect to the adjusted EBITDA of the Issuer as calculated pursuant to the terms of the Merger Agreement for the 2018 fiscal year and/or 2019 fiscal year ("EBITDA Earn-Out Shares"). Seller's right to receive up to an additional 9,000,000 shares of Common Stock (which are not included in the number of shares reflected in the table) pursuant to this earn-out right became fixed and irrevocable on March 26, 2018, the effective date of the Mergers.

Seller's right to receive up to an additional 525,000 shares of Common Stock (which are not included in the number of shares reflected in the table) became fixed and irrevocable on March 26, 2018, the effective date of the Mergers. ( 4 )The controlling equityholder of Seller is Oaktree Power Opportunities Fund III Delaware, L.P. The general partner of Oaktree Power Opportunities Fund III Delaware, L.P. is Oaktree Fund GP, LLC. The managing member of Oaktree Fund GP, LLC is Oaktree Fund GP I, L.P. The general partner of Oaktree Fund GP I, L.P. is Oaktree Capital I, L.P. The general partner of Oaktree Capital I, L.P. is OCM Holdings I, LLC. The managing member of OCM Holdings I, LLC is Oaktree Holdings, LLC.

( 6 )Oaktree Capital Group Holdings GP, LLC is managed by an executive committee consisting of Howard S. Marks, Bruce A. Karsh, Sheldon M. Stone, John B. Frank and Jay S. Wintrob (the "OCGH GP Members"). Each OCGH GP Member expressly disclaims beneficial ownership of the equity securities reported herein, except to the extent of his respective pecuniary interests therein, and the filing of this Form 3 shall not be construed as an admission that any such person is the beneficial owner of any equity securities covered by this Form 3.

( 8 )In connection the Mergers, Seller acquired 34,965 shares of the Issuer's Series A Preferred Stock (the "Preferred Stock"). Holders of Preferred Stock may elect to cause the Issuer to convert the Preferred Stock into Common Stock (x) at any time on or after March 26, 2021 or (y) at any time on or after an event of default until such event of default is cured by the Issuer. The conversion price will equal the volume-weighted average price per share of Common Stock for the 30 consecutive trading days ended on the trading day immediately prior to the date of conversion (multiplied by 90% if an event of default has occurred and has not been cured). Because the Preferred Stock is not yet convertible and because the conversion price thereunder has not been fixed, the Reporting Persons have no beneficial ownership of any shares of Common Stock that would be received upon such conversion.
