completion of the proposed business combination. These statements are based on various assumptions, whether or not identified in this press release, and on the current expectations of the respective management of Altitude and Picard and are not predictions of actual performance. These forward-looking statements are provided for illustrative purposes only and are not intended to serve as, and must not be relied on by an investor as, a guarantee, an assurance, a prediction or a definitive statement of fact or probability. Actual events and circumstances are difficult or impossible to predict and will differ from assumptions. Many actual events and circumstances are beyond the control of Altitude and Picard. These forward-looking statements are subject to a number of risks and uncertainties, including changes in domestic business, market, financial, political, and legal conditions; the inability of the parties to successfully or timely consummate the proposed business combination, including the risk that any regulatory approvals are not obtained, are delayed or are subject to unanticipated conditions that could adversely affect the combined company or the expected benefits of the proposed business combination or that the approval of the stockholders of Altitude or Picard is not obtained; failure to realize the anticipated benefits of the proposed business combination; risks relating to the uncertainty of the projected financial information with respect to Picard; risks related to the performance of Picard’s business; the development, effects and enforcement of laws and regulations; Picard’s ability to manage future growth; Picard’s ability to develop new products and solutions, bring them to market in a timely manner, and make enhancements to its platform; the effects of competition on Picard’s business; the amount of redemption requests made by Altitude’s stockholders; the ability of Altitude or Picard to obtain financing in connection with the proposed business combination or in the future; the outcome of any potential litigation, government and regulatory proceedings, investigations and inquiries; and those factors discussed in the preliminary proxy statement under the heading “Risk Factors,” and other documents Altitude has filed, or will file, with the SEC. If any of these risks materialize or our assumptions prove incorrect, actual results could differ materially from the results implied by these forward-looking statements. There may be additional risks that neither Altitude nor Picard presently know, or that Altitude or Picard currently believe are immaterial, that could also cause actual results to differ from those contained in the forward-looking statements. In addition, forward-looking statements reflect Altitude’s and Picard’s expectations, plans, or forecasts of future events and views as of the date of this press release. Altitude and Picard anticipate that subsequent events and developments will cause Altitude’s and Picard’s assessments to change. However, while Altitude and Picard may elect to update these forward-looking statements at some point in the future, Altitude and Picard specifically disclaim any obligation to do so.

Accordingly, undue reliance should not be placed upon the forward-looking statements.
