Use of Forward-Looking Statements

This document includes certain "forward-looking statements" within the meaning of, and subject to the safe harbor created by, Section 21E of the Securities Exchange Act of 1934, as amended, with respect to the business, strategy and plans of the Company. Statements that are not historical facts are forward-looking statements. Words such as "believes," "anticipates," "estimates," "expects," "intends," "aims," "potential," "will," "would," "could," "considered," "likely," "estimate" and variations of these words and similar future or conditional expressions are intended to identify forward-looking statements but are not the exclusive means of identifying such statements. While the Company believes these forward-looking statements are reasonable, such forward-looking statements are only predictions and involve known and unknown risks and uncertainties, many of which are beyond the Company's control. By their nature, forward-looking statements involve risk and uncertainty because they relate to events and depend upon future circumstances that may or may not occur. Actual results may differ materially from the Company's current expectations depending upon a number of factors affecting the business and risks associated with the performance of the business. These factors include such risks and uncertainties, including and in addition to any assumptions set forth therein, but not limited to, the ongoing assessment of the security event, material legal, financial and reputational risks resulting from a breach of the Company's information systems, operational disruptions due to a security event, and any other risks detailed in the Company's periodic public filings with the Securities and Exchange Commission (the "SEC"), including but not limited to those discussed under the "Risk Factors" section in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2020 and Quarterly Reports on Form 10-Q for the quarters ended March 31, 2021, June 30, 2021 and September 30, 2021 and other filings with the SEC and in other investor communications of the Company from time to time. The Company does not undertake to and specifically disclaims any obligation to publicly release the results of any revisions to these forward-looking statements that may be made to reflect future events or circumstances after the date of such statement or to reflect the occurrence of anticipated or unanticipated events.
