(“Parent”) pursuant to the terms of the previously announced Agreement and Plan of Merger (the “Merger Agreement”) entered into on December 14, 2021 by and among the Company, Parent and Chatham Delta Acquisition Sub, Inc. (“Acquisition Sub”). Under the terms of the Merger Agreement, Acquisition Sub will merge with and into the Company (the “Merger”), with the Company surviving the Merger as a wholly owned subsidiary of Parent.

The Company is offering a cash payment (the “Consent Consideration”) for certain series of Debt Securities to Holders (as defined below) of such Debt Securities who validly deliver consents (“Consents”) to the Proposed Amendments. The following table sets forth the Consent Consideration for each series of Debt Securities in the Consent Solicitations:

(1) Parent and its affiliates collectively own over 50% of the outstanding Debt Securities of the specified series as of the record date for the Consent Solicitations. The Company has been informed that Parent and its affiliates intend to consent to the Proposed Amendments. As such, no Consent Consideration will be paid for such series of Debt Securities.

The Consent Solicitations are subject to the terms and conditions set forth in the consent solicitation statement, dated January 20, 2022 (the “Consent Solicitation Statement”), which is being distributed to Holders of the Debt Securities.

The expiration date (such time and date in respect of one or more series of Debt Securities as set forth below, the “Expiration Date”) for the Consent Solicitation with respect to the 2027 Notes and the 2029 Notes will be 5:00 p.m., New York City time, on January 27, 2022 and with respect to the 2023 Notes, the 2024 Notes, the 2026 Notes, the 2029 Debentures and the 2031 Debentures will be 5:00 p.m., New York City time, on February 1, 2022, in each case, unless extended or earlier terminated by the Company in its sole discretion with respect to one or more series of Debt Securities. The applicable Expiration Date may be amended with respect to any series of Debt Securities; however, there is no requirement to also amend the applicable Expiration Date for any other series of Debt Securities or for all series of Debt Securities.

In order to receive the Consent Consideration (if applicable), registered holders of the Debt Securities of record (each a “Holder” and, collectively, the “Holders”) at 5:00 p.m., New York City time, on January 18, 2022, need to validly deliver their Consents prior to 5:00 p.m., New York City time, on the applicable Expiration Date. Payment of the Consent Consideration (if applicable) for the Debt Securities is conditioned upon the receipt by the Company of the Consents of a majority in aggregate principal amount of the outstanding Debt Securities, other than Debt Securities beneficially owned by the Company or any of its affiliates (the “Requisite Consents”). The Consent Consideration (if applicable) for the Debt Securities will be paid as promptly as practicable after the time at which all the conditions with respect to the Consent Solicitations, including the consummation of the Merger, have been satisfied or waived. Holders of Debt Securities for which no Consent is validly delivered prior to the applicable Expiration Date (or for which a Consent is validly delivered and later validly revoked) will not receive the Consent

Consideration (if applicable), even though the Proposed Amendments, if they become operative, will bind all Holders and any subsequent holders of the Debt Securities. Pursuant to the terms of the Merger Agreement, Parent will be responsible for paying or reimbursing the Company for the Consent Consideration to the Holders who validly deliver (and not validly revoke) Consents prior to the applicable Expiration Date. No Consent Consideration will be paid for the 2026 Notes, 2027 Notes and 2029 Notes.

Each Holder who delivers a Consent to the Proposed Amendments in accordance with the procedures set forth in the Consent Solicitation Statement will be deemed to have consented to all of the Proposed Amendments applicable to such series of Debt Securities.

The Company expects to execute a supplemental indenture with respect to each series of Debt Securities after the Requisite Consents have been obtained to adopt the Proposed Amendments. Upon its execution, each supplemental indenture will be effective and constitute binding agreements among the Company, the guarantors party thereto (where applicable) and the applicable trustee. However, the Proposed Amendments will not become operative until immediately prior to the consummation of the Merger and will cease to be operative if the Merger is not consummated or the Consent Consideration is not paid to the Holders.

The effectiveness of the Proposed Amendments is not a condition to the consummation of the Merger or other transactions contemplated by the Merger Agreement, but the consummation of the Merger is a condition to the effectiveness of the Supplemental Indentures and the payment of the Consent Consideration. Based on the information currently available to the Company, it is expected that the Merger will be consummated during the first quarter of 2022; however, there is no assurance that the Merger will be consummated in the first quarter of 2022 or at any time prior to the Termination Date (as defined in the Merger Agreement) (which is subject to extension under certain limited circumstances as described herein).

The Company may, in its sole discretion, terminate, extend or amend the Consent Solicitation with respect to one or more series of Debt Securities at any time as described in the Consent Solicitation Statement. The Company reserves the right to amend the Consent Solicitation with respect to one or more series of Debt Securities, including the Consent Consideration and the applicable Expiration Date, and not the other series of Debt Securities. If the Consent Solicitation with respect to one or more series of Debt Securities is terminated or the Company does not receive the Requisite Consent for one or more series of Debt Securities, the Proposed Amendments will have no effect on the applicable Indenture, such series of Debt Securities or the Holders of such Debt Securities.

The Company, at the request of Parent, has engaged Jefferies LLC to act as solicitation agent (“Solicitation Agent”) in connection with the Consent Solicitations. Questions regarding the Consent Solicitation may be directed to the Solicitation Agent at the following address or telephone number: Jefferies LLC, 520 Madison Avenue, New York, NY 10022, Attn: Scott Peloso, (212) 284-3426.

This news release does not constitute a solicitation of consents with respect to any Debt Securities, and the Consent Solicitations are only being made pursuant to the terms of the Consent Solicitation Statement. The Consent Solicitations are not being made to, and Consents are not being solicited from, Holders of Debt Securities in any jurisdiction in which it is unlawful to make such Consent Solicitations or grant such consent. None of the Company, the trustees, the Solicitation Agent or the Information and Tabulation Agent makes any recommendation as to whether or not Holders should deliver Consents. Each Holder must make its own decision as to whether or not to deliver Consents.

Use of Forward-Looking Statements

This news release 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 Merger. 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 Merger 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 Merger 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 Merger on anticipated terms and timing, including obtaining required stockholder and regulatory approvals and the satisfaction of other conditions to the completion of the Merger; (ii) significant transaction costs associated with the Merger; (iii) potential litigation relating to the Merger, including the effects of any outcomes related thereto; (iv) the risk that disruptions from the Merger 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 Merger; (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 Merger that could affect the Company’s financial performance; (xi) certain restrictions during the pendency of the Merger 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 Merger; (xiv) the occurrence of any event, change or other circumstance that could give rise to the termination of the Merger, 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 Merger; (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 Merger and available from the sources indicated below (the “Proxy Statement”). These risks, as well as other risks associated with the Merger are more fully discussed in 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. Unlisted factors may present significant additional obstacles to the realization of forward-looking statements. Consequences of material differences in results as compared with those anticipated in the forward-looking statements could include, among other things, business disruption, operational problems, financial loss, legal liability to third parties and similar risks, any of which could have a material impact on the Company’s financial condition, results of operations, credit rating or liquidity or ability to consummate the Merger. These forward-looking statements speak only as of the date they are made, and the Company does not undertake to and disclaims any obligation to publicly release the results of any updates or revisions to these forward-looking statements that may be made to reflect future events or circumstances after the date of such statements or to reflect the occurrence of anticipated or unanticipated events.
