OFFICE SPACE AND RELATED SERVICES AGREEMENT

This OFFICE SPACE AND RELATED SERVICES AGREEMENT (this “AGREEMENT”) is made as of October [    ], 2017 by and between [Mosaic Strategic Capital LLC], a Delaware limited liability company (“MSC”), and Mosaic Acquisition Corp., a Cayman Islands exempted company (the “Company”) (collectively referred to herein as the “Parties”, and each a “Party”).

WHEREAS, the Company and MSC desire to enter into this Agreement to set forth the terms and conditions upon which MSC will provide certain ongoing services to the Company as described herein.

NOW, THEREFORE, and in consideration of the mutual covenants, rights, and obligations set forth in this Agreement, the benefits to be derived therefrom, and other good and valuable consideration, the receipt and the sufficiency of which are hereby acknowledged, the Parties agree as follows:

1. TERM. The term of this Agreement shall commence on [●], 2017 and shall continue in effect until terminated by either Party to this Agreement following ten (10) days advance written notice to the other Party (the “Term”) or such other amount of days as agreed to by the Parties in writing.

2. OFFICE SPACE AND SERVICES TO BE PROVIDED.

(a) During the Term, MSC shall (i) provide the Company with unrestricted access to and use of its offices located at Suite 2607, 375 Park Avenue, New York, New York 10152, or such other location as the Parties may from time to time agree in writing (the “Office Space”), and the equipment located in the Office Space (the “Equipment), including, without limitation, any Bloomberg terminal, (ii) provide, or cause to be provided, those services to the Company that are reasonably requested by the Company from time to time in connection with the Company’s use of the Office Space and the Equipment and (iii) make available to the Company those employees of MSC requested by the Company from time to time to perform such services (each, an “MSC Service Provider”), as reasonably requested by the Company and subject to any limitations on the provision of Services (as defined below) contained in any employment agreement between an MSC Service Provider and MSC or any other agreement (such services listed in clause (ii) and (iii) of this Section 2(a), the “Services”). MSC shall use commercially reasonable efforts to cause the Office Space, the Equipment and the Services to be provided to the Company; provided that, MSC shall be under no obligation to (A) provide access to any MSC Service Provider if such person’s employment with MSC has been terminated or such person refuses or is unable to perform Services; (B) provide any Service if MSC determines in good faith that any applicable law or regulation prevents or prohibits MSC from providing such Service or MSC is unable to obtain the requisite consents, approvals or authorizations to provide such Service; (C) provide any Service if a third party contractor ceases to provide Services to MSC

such that MSC can no longer provide such Service, (D) provide any Service if MSC ceases to provide such Service to itself or its affiliated funds or (E) provide access to any Office Space or Equipment if such access would violate applicable law or regulation, a confidentiality or similar obligation of MSC or the terms of MSC’s lease with respect to such Office Space or Equipment; provided, that in each such circumstance described in clauses (A) through (E) of this Section 2(a), each Party shall cooperate in good faith and use commercially reasonable efforts to determine the best alternative approach. The Office Space, the Equipment and the Services shall be provided on an as-needed, non-exclusive basis within a reasonable time after the Company requests such Office Space, Equipment and Services. At any time during the Term, the Company may in its sole discretion reduce or increase the level of use of the Services or terminate or add one or more Services on a prospective basis, including reducing or increasing the number of MSC Service Providers.

(b) The Parties mutually acknowledge and agree that the execution of this Agreement and the performance of Services hereunder shall not constitute a breach of, or otherwise contravene the terms of any employment agreement or other agreement or policy to which the Company or MSC is a party or otherwise bound. Notwithstanding the above, except as expressly set forth herein, the Parties acknowledge and agree that the Office Space, the Equipment and the Services are provided as-is, that the Company assumes all risks and liabilities arising from or relating to its use of and reliance upon the Office Space, the Equipment and the Services, and neither MSC nor any individual providing the Office Space, the Equipment or the Services, as applicable, makes any representation or warranty with respect thereto. Except as expressly set forth herein, MSC and the individuals providing the Office Space, the Equipment and the Services, as applicable, hereby expressly disclaim all representations and warranties regarding the Office Space, the Equipment and the Services, whether express or implied, including any representation or warranty in regard to quality, performance, noninfringement, compliance with laws or regulations (domestic and foreign), commercial utility, merchantability or fitness of the Office Space, the Equipment or the Services for a particular purpose.

3. FEES. In consideration of the provision of the Office Space, the Equipment and the Services and unless terminated sooner under the terms of this Agreement, the Company shall pay to MSC a fee of $16,875 per month (including $1,875 per month for use of the Equipment), which shall be subject to proration for any partial month during the Term.

4. EMPLOYEES DEEMED TO BE CONSULTANTS. Employees of MSC engaged in performing the Services shall be considered to be providing such Services to the Company as its consultants. Under no circumstances (including federal, state and local law) shall such employees be considered to be employees of the Company.
