Cautionary Note Regarding Forward-Looking Statements
This communication contains forward-looking statements related to the Buyer and LAVA and the acquisition by the Buyer of LAVA, including
express or implied forward-looking statements about the future operations and performance of LAVA and Buyer. These forward-looking statements are within the meaning of U.S. federal securities laws, including, without limitation, statements regarding
the anticipated timing of and closing of the proposed Offer and related transactions contemplated by the Purchase Agreement (collectively referred to as the “transactions”). The words “anticipate,” “approximately,”
“look to,” “plan,” “expect,” “may,” “will,” “could” or “should,” the negative of these terms or similar expressions are intended to identify forward-looking statements, although
not all forward-looking statements contain these identifying words. These statements are based on current plans, estimates and projections. By their very nature, forward-looking statements involve inherent risks and uncertainties, both general and
specific. The Buyer cautions that a number of important factors, including those described in this communication, could cause actual results to differ materially from those contemplated in any forward-looking statements. Any forward-looking
statements in this communication are based on management’s current expectations and beliefs and are subject to a number of risks, uncertainties and important factors that may cause actual events or results to differ materially from those
expressed or implied by any forward-looking statements contained in this communication, including, without limitation, the impact of actions of other parties with respect to the transactions; the possibility that competing offers will be made; the
outcome of any legal proceedings that have been or could be instituted against the Buyer , LAVA or their respective directors; the risk that the transactions may not be completed in a timely manner, or at all, which may adversely affect LAVA’s
or Buyer’s respective businesses and the price of their respective shares of capital stock; the failure to satisfy all of the closing conditions of the transactions contemplated by the Purchase Agreement; the occurrence of the events giving
rise to payments under the Contingent Value Rights (“CVR”) Agreement; the occurrence of any event, change or other circumstance that could give rise to the termination of the Purchase Agreement; the effect of the announcement or
pendency of the transactions on LAVA’s and Buyer’s respective businesses and operating results; risks that the transactions may disrupt LAVA’s or Buyer’s respective current plans and business operations; risks related to the
diverting of management’s attention from LAVA’s and Buyer’s respective ongoing business operations; general economic and market conditions and the other risks identified in LAVA’s and Buyer’s respective filings with the SEC
and subsequent filings with the SEC. Should any risks and uncertainties develop into actual events, these developments could have a material adverse effect on the transactions and/or LAVA and the Buyer’s ability to successfully complete the
transactions and, with respect to any CVR payment amounts, the consideration ultimately paid to LAVA shareholders (including whether any payments will be payable at all). In addition, unlisted factors may present significant additional obstacles to
the realization of forward-looking statements. The Buyer cautions investors not to place undue reliance on any forward-looking statements. Any forward-looking statements contained in this communication represent the Buyer’s views only as of the
date hereof and should not be relied upon as representing its views as of any subsequent date. The Buyer disclaims any obligation to publicly update or revise any such statements to reflect any change in expectations or in events, conditions or
circumstances on which any such statements may be based, or that may affect the likelihood that actual results will differ from those set forth in the forward-looking statements.
