This message has been sent to MVW and ILG Managers and above.

Action Requested: Please review the attached Manager Tool Kit and plan to attend one of the Open Chat Sessions scheduled for early September.

We are pleased to announce that the milestone of receiving Shareholder approval has been reached and the Joint Integration Team is now focused on closing the MVW/ILG transaction, which is scheduled to be completed on Saturday, September 1 (effective 12:02 a.m., EDT), provided that all other remaining conditions to closing are satisfied.

As we continue to finalize the last few details related to the completion of the merger, we want to ensure that leaders of both organizations are prepared for the transition. We know you and your associates have questions; therefore, we look forward to speaking with you at one of the Open Chat sessions scheduled for early September.

Manager Tool Kit + Associate Integration Guide

The Communications and Change Management Team has crafted two internal guides for Day 1 of the new organization – 1) a Manager Tool Kit and 2) an Associate Integration Guide. We have provided links to both guides to this email to prepare you for Day 1. The Manager Tool Kit includes an overview of the integration, guidance on how best to communicate with your associates, and a sample team presentation. The Associate Integration Guide includes information on the new company, an overview of what’s changing and what’s not, and key resources for further information. The Associate Integration Guide will be accessible via the Integration Hub on September 1, 2018. Note: the links embedded in both guides will not work until the Integration Hub is launched on September 1, 2018.

Prior to attending one of the Open Chat sessions, please take a moment to review and submit any questions you may have to the Integration mailbox at mvw.integration@mvwc.com. During the session, key parts of the Manager Tool Kit will be highlighted, in addition to answering as many questions as possible.

Cautionary Statement Regarding Forward-Looking Statements

Information included or incorporated by reference in this communication, and information which may be contained in other filings with the Securities and Exchange Commission (the “SEC”) and press releases or other public statements, contains or may contain “forward-looking” statements, as that term is defined in the Private Securities Litigation Reform Act of 1995 or by the SEC in its rules, regulations and releases. 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. Among other things, these forward-looking statements may include statements regarding the proposed combination of MVW and ILG; our beliefs relating to value creation as a result of a potential combination of MVW and ILG; the expected timetable for completing the transactions; benefits and synergies of the transactions; future opportunities for the combined company; and any other statements regarding MVW’s and ILG’s future beliefs, expectations, plans, intentions, financial condition or performance. In some cases, forward-looking statements can be identified by the use of words such as “may,” “will,” “expects,” “should,” “believes,” “plans,” “anticipates,” “estimates,” “predicts,” “potential,” “continue,” or other words of similar meaning.

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. Except as required by law, we disclaim any obligation to review or update these forward-looking statements to reflect events or circumstances as they occur.
