Communications Guidance

Understanding WHAT’S ON THE Mind of an Associate The first step to being an effective manager of associates during the integration is understanding what is on your associates’ mind. Throughout this section of the Tool Kit, we provide guidance on communicating with your associates and resources to help you share information effectively.

Manager Responsibilities Mangers are responsible for ensuring associates understand the integration and feel part of the new MVW. Managers should help associates understand: The role they will play in the new company The new MVW’s shared ambition statement How the integration will benefit key stakeholders Managers should make sure that associates feel: They have been provided with a clear direction Aligned with organizational goals and ambitions That communications have been open, honest, and timely Motivated and inspired to continue working to high standards and delivering outstanding service to all customers

Guidance for Communicating with Associates DO: Provide presence and visibility to engage with all associates and create an atmosphere of dialogue and support, especially during staff meetings Keep an open-door policy to encourage associates to approach you Host a team meeting to discuss the integration with your associates If you don’t know the answer to an associate question, let them know that you will look into it and follow up with a response Encourage associates to review available resources to guide them through the integration. Be aware that your attitude, behavior, and language will impact how your team feels about the integration DO NOT: Speculate about the future with associates Guess if you don’t know the answer to a question (do tell associates you will follow up with them once you have the necessary information)

Guidance on Communicating Organizational Changes We have been working hard to create an organization that will give you and your teams the best opportunities in the future. We know that you will be getting questions from your associates on the new organizational structure and wanted to give you visibility to the timeline and resources to answer these questions. Timeline: End of November 2018 is our target date for selecting and communicating our senior leadership team End of First Quarter 2019 is when senior leadership will target to have a decision around the future design of the organization and related key roles and responsibilities. Plans will continue to evolve in the coming year as we continue to refine our strategic direction Resources: Review the Integration FAQs on the Integration Hub that address questions we anticipate you may have about the new operating model and leadership structure, the talent selection process, and equally as important, how organizational changes may affect you and/or your teams.

These forward-looking statements include, among other things, statements of plans, objectives, expectations (financial or otherwise) or intentions. Forward-looking statements are any statements other than statements of historical fact, including statements regarding MVW and ILG, Inc.’s (“ILG”) expectations, beliefs, hopes, intentions or strategies regarding the future.

Forward-looking statements are subject to risks and uncertainties that could cause actual results to differ materially from those discussed in, or implied by, the forward-looking statements. Factors that might cause such a difference include, but are not limited to, general economic conditions, our financial and business prospects, our capital requirements, our financing prospects, our relationships with associates and labor unions, our ability to consummate potential acquisitions or dispositions, our relationships with the holders of licensed marks, and those additional factors disclosed as risks in other reports filed by us with the SEC, including those described in Part I of the MVW’s most recently filed Annual Report on Form 10-K and subsequent reports on Forms 10-Q and 8-K as well as in ILG’s most recently filed Annual Report on Form 10-K and subsequent reports on Forms 10-Q and 8-K and in the joint proxy statement/prospectus included in the registration statement on Form S-4 filed by MVW with the SEC, and any amendments thereto. Other risks and uncertainties include the timing and likelihood of completion of the proposed transactions between MVW and ILG; the possibility that the expected synergies and value creation from the proposed transactions will not be realized or will not be realized within the expected time period; the risk that the businesses of MVW and ILG will not be integrated successfully; the potential impact of disruption from the proposed transactions making it more difficult to maintain business and operational relationships; the risk that unexpected costs will be incurred; the ability to retain key personnel; the availability of financing; the possibility that the proposed transactions do not close; as well as more specific risks and uncertainties. You should carefully consider these and other relevant factors, including those risk factors in this communication and other risks and uncertainties that affect the businesses of MVW and ILG described in their respective filings with the SEC, when reviewing any forward-looking statement. These factors are noted for investors as permitted under the Private Securities Litigation Reform Act of 1995. We caution readers that any such statements are based on currently available operational, financial and competitive information, and they should not place undue reliance on these forward-looking statements, which reflect management’s opinion only as of the date on which they were made.
