Use of Forward-Looking Statements

This document includes certain “forward-looking statements” within the meaning of, and subject to the safe harbor created by, the federal securities laws, including statements related to the proposed acquisition of the Company by affiliates of Chatham Asset Management, LLC (the “Transaction”). These forward-looking statements are based on the Company’s current expectations, estimates and projections regarding, among other things, the expected date of closing of the Transaction and the potential benefits thereof, its business and industry, management’s beliefs and certain assumptions made by the Company, all of which are subject to change. Forward-looking statements often contain words such as “expect,” “anticipate,” “intend,” “aims,” “plan,” “believe,” “could,” “seek,” “see,” “will,” “may,” “would,” “might,” “considered,” “potential,” “estimate,” “continue,” “likely,” “target” or similar expressions or the negatives of these words or other comparable terminology that convey uncertainty of future events or outcomes. By their nature, forward-looking statements address matters that involve risks and uncertainties because they relate to events and depend upon future circumstances that may or may not occur, such as the consummation of the Transaction and the anticipated benefits thereof. These and other forward-looking statements are not guarantees of future results and are subject to risks, uncertainties and assumptions that could cause actual results to differ materially from those expressed in any forward-looking statements. Important risk factors that may cause such a difference include (i) impediments to the completion of the Transaction on anticipated terms and timing, including obtaining required stockholder and regulatory approvals and the satisfaction of other conditions to the completion of the Transaction; (ii) significant transaction costs associated with the Transaction; (iii) potential litigation relating to the Transaction, including the effects of any outcomes related thereto; (iv) the risk that disruptions from the Transaction will harm the Company’s business, including current plans and operations; (v) the ability of the Company to retain and hire key personnel; (vi) potential adverse reactions or changes to business relationships resulting from the announcement or completion of the Transaction; (vii) legislative, regulatory and economic developments affecting the Company’s business; (viii) general economic and market developments and conditions; (ix) the evolving legal, regulatory and tax regimes under which the Company operates; (x) potential business uncertainty, including changes to existing business relationships, during the pendency of the Transaction that could affect the Company’s financial performance; (xi) certain restrictions during the pendency of the Transaction that may impact the Company’s ability to pursue certain business opportunities or strategic transactions; (xii) continued availability of capital and financing and rating agency actions; (xiii) the ability of affiliates of Chatham Asset Management, LLC to obtain the necessary financing arrangements set forth in the commitment letters received in connection with the Transaction; (xiv) the occurrence of any event, change or other circumstance that could give rise to the termination of the Transaction, including in circumstances requiring the Company to pay expense reimbursements to affiliates of Chatham Asset Management, LLC under the Merger Agreement; (xv) unpredictability and severity of catastrophic events, including acts of terrorism, outbreak of war or hostilities, civil unrest, adverse climate or weather events or the COVID-19 pandemic or other public health emergencies, as well as the Company’s response to any of the aforementioned factors; (xvi) competitive responses to the Transaction;

(xvii) the risks and uncertainties pertaining to the Company’s business, including those detailed under the heading “Risk Factors” and elsewhere in the Company’s public filings with the U.S. Securities and Exchange Commission (the “SEC”); and (xviii) the risks and uncertainties described in the proxy statement filed in connection with the Transaction and available from the sources indicated below (the “Proxy Statement”).

While the list of factors presented here is, and the list of factors presented in the Proxy Statement are, considered representative, no such list should be considered to be a complete statement of all risks and uncertainties.
