Explanation of Responses:
(1)	Support.com, Inc., a Delaware corporation (the "Company"), entered into an Agreement and Plan of Merger (the "Merger Agreement"), dated as of March 19, 2021, by and among the Company, Greenidge Generation Holdings Inc., a Delaware corporation ("Greenidge") and GGH Merger Sub, Inc., a Delaware corporation and wholly owned subsidiary of Greenidge ("Merger Sub"). On September 14, 2021, Merger Sub merged with and into the Company, the separate corporate existence of Merger Sub ceased and the Company survived the merger as a direct wholly owned subsidiary of Greenidge.
