In addition, Company representatives may from time to time make oral forward-looking statements. All statements, other than statements of historical facts, are forward-looking statements. Forward-looking statements may be identified by the words “anticipate,” believe,” “estimate,” “expect,” “intend,” “plan,” “project,” “may,” “will,” “could,” “should,” “seek” and similar expressions.

While management believes the Company’s assumptions are reasonable, the Company cautions against

relying on any forward-looking statements as it is very difficult to predict the impact of known factors, and it is impossible for management to anticipate all factors that could affect the Company’s actual results. Important factors that could cause actual results to differ materially from those in the forward-looking statements include, but are not limited to, the Debtors’ ability to obtain the approval of the Bankruptcy Court with respect to motions filed in the Chapter 11 Cases and the outcomes of Bankruptcy Court rulings and the Chapter 11 Cases in general, the effectiveness of the overall restructuring activities pursuant to the Chapter 11 Cases and any additional strategies that the Debtors may employ to address their liquidity and capital resources, the actions and decisions of creditors, regulators and other third parties that have an interest in the Chapter 11 Cases, restrictions on the Debtors due to the terms of anydebtor-in-possession credit facility that the Debtors may enter into in connection with the Chapter 11 Cases and restrictions imposed by the Bankruptcy Court, increased legal and other professional costs necessary to execute the Debtors’ restructuring, the trading price and volatility of the Company’s common stock and the effects of the Chapter 11 Cases on the Company’s continued listing on the New York Stock Exchange, the effects and the length of the 2019 novel coronavirus(COVID-19) pandemic and the other factors listed in the Company’s SEC filings.
