Explanation of Responses:	
(1) 	Pursuant to an Agreement and Plan of Merger, dated effective as of September 15, 2019, as amended by that certain Amendment No. 1 and as otherwise amended from time to time (the "Merger Agreement"), by and among Legacy Vivint Smart Home, Inc. (f/k/a Vivint Smart Home, Inc.) ("Legacy Vivint Smart Home"), Mosaic Acquisition Corp. ("Mosaic") and Maiden Merger Sub, Inc. ("Merger Sub"), Merger Sub merged (the "Merger") with and into Legacy Vivint Smart Home, with Legacy Vivint Smart Home surviving the merger as a wholly owned subsidiary of Mosaic (which subsequently changed its name to "Vivint Smart Home, Inc.", the "Issuer"). The transactions contemplated by the Merger Agreement closed on January 17, 2020.	
(2) 	Pursuant to the terms of the Merger Agreement, the stockholders and holders of equity awards of Legacy Vivint Smart Home at the effective time of the Merger received, among other consideration, certain rights to additional shares of Class A common stock of the Issuer ("Class A Common Stock") or to have the terms and conditions of their equity awards equitably adjusted, in each case, upon the achievement of certain milestones as described in the Merger Agreement (the "Earnout Rights"). Pursuant to earnout provisions in the Merger Agreement, the Reporting Person is entitled to receive such shares of Class A Common Stock and/or have the terms and conditions of their equity award equitably adjusted if, from the closing of the Merger until the fifth anniversary thereof, the volume-weighted average price of the Class A Common Stock exceeds certain thresholds as discussed below, subject to the terms of the Merger Agreement.	
(3) 	Of these Earnout Rights, one-third are earned if the volume-weighted average price of the Class A Common Stock exceeds $12.50 for any 20 trading days within any 30 trading day period (the "$12.50 Condition"), one-third are earned if the volume-weighted average price of the Class A Common Stock exceeds $15.00 for any 20 trading days within any 30 trading day period (the "$15.00 Condition"), and one-third are earned if the volume-weighted average price of the Class A Common Stock exceeds $17.50 for any 20 trading days within any 30 trading day period (the "$17.50 Condition"). The Earnout Rights are subject to certain adjustments, including pro rata adjustments, set forth in the Merger Agreement. The $12.50 Condition was satisfied on February 26, 2020.	
(4) 	Reflects, upon satisfaction of the $12.50 Condition, the issuance of the following: (a) 991 shares of Class A Common Stock, (b) 3,297 additional shares of restricted Class A Common Stock, which vest upon the vesting of the restricted Class A Common Stock held by the Reporting Person to which they relate, and (c) the right to receive 2,474 shares of Class A Common Stock, which vest upon the settlement of the restricted stock units to which they relate.
