As an inducement for Insight to consummate the Merger, the Founders and Insight have entered into a support agreement (the “Support Agreement). Pursuant to the Support Agreement, each Founder and each such Founder’s affiliated entity as party thereto has agreed, among other things, to vote all of the Ordinary Shares beneficially owned by him in favor of the authorization and approval of the Merger Agreement and the transactions contemplated thereunder.
