Explanation of Responses:	
(1) 	Pursuant to the Issuer's Certificate of Incorporation, the shares of Class F Common Stock, par value $0.0001 per share (the "Class F Shares"), of Mosaic Acquisition Corp. (the "Issuer") automatically converted into shares of Class A Common Stock ("Class A Shares") of the Issuer at the time of the Issuer's initial business combination as provided in the Issuer's Certificate of Incorporation. The Class F Shares have no expiration date.	
(2) 	On January 17, 2020, the Issuer consummated its initial business combination (the "Business Combination") with Vivint Smart Home, Inc., a Delaware corporation ("Vivint"). In connection with the Business Combination, each Class F Share converted to approximately 1.20 Class A Shares.	
(3) 	In connection with the Business Combination, Mosaic Sponsor, LLC forfeited 1,074,375 Class F Shares to the Issuer pursuant to the Subscription Agreement, dated as of December 18, 2019, among Fayerweather Fund Eiger L.P., the Issuer, Mosaic Sponsor, LLC and Vivint.	
(4) 	Represents Class A Shares owned directly by David M. Maura.	
(5) 	The Private Placement Warrants were purchased by Mosaic Sponsor, LLC on October 23, 2017. Each Private Placement Warrant is exercisable for one Class A Share at an exercise price of $11.50 per Class A Share, subject to certain adjustments. The Private Placement Warrants are subject to certain vesting provisions and may be exercised only during the period commencing 30 days after the first date on which the Company completes a business combination and expiring five years after the completion of the Company's business combination or earlier upon redemption or liquidation.	
(6) 	The securities reported herein are held of record by Mosaic Sponsor, LLC. David M. Maura is the sole member of Mosaic Strategic Capital LLC, which is the sole member of Mosaic Sponsor, LLC. As such, David M. Maura and Mosaic Strategic Capital LLC may be deemed to have beneficial ownership of the securities beneficially owned by Mosaic Sponsor, LLC.

(cont'd on FN 7)	
(7) 	(cont'd from FN 6) Each reporting person disclaims beneficial ownership of the securities reported herein, except to the extent of such reporting person's pecuniary interest therein, if any. Pursuant to Rule 16a-1(a)(4) under the Exchange Act, this filing shall not be deemed an admission that the reporting persons are, for purposes of Section 16 of the Exchange Act or otherwise, the beneficial owners of any equity securities in excess of their respective pecuniary interests.	

Remarks:
Mosaic Sponsor, LLC may be deemed a directory by deputization as a result of David M. Maura, the sole member of Mosaic Strategic Capital LLC, which is the sole member of Mosaic Sponsor, LLC, serving on the board of directors of the Issuer. As a result of the Business Combination, the reporting persons have ceased to beneficially own more than 10% of the outstanding common stock of the Issuer and David M.
