In conjunction with the Exchange Offers, the Grace Issuer is soliciting consents (each, a “Consent Solicitation” and, collectively, the “Consent Solicitations”) to adopt certain proposed amendments to each of the indentures governing the Existing Grace Notes to eliminate certain of the covenants, restrictive provisions, events of default and guarantee provisions from such indentures.

The Exchange Offers and Consent Solicitations are being made pursuant to the terms and subject to the conditions set forth in the offering memorandum and consent solicitation statement dated August 3, 2021 (the “Offering Memorandum and Consent Solicitation Statement”).

Each Exchange Offer and Consent Solicitation is conditioned upon the completion of the other Exchange Offers and Consent Solicitations, although Holdings may waive such condition at any time with respect to an Exchange Offer. Any waiver of a condition by Holdings with respect to an Exchange Offer will automatically waive such condition with respect to the corresponding Consent Solicitation, as applicable.

In addition, the Exchange Offers and Consent Solicitations are conditioned upon the consummation of the transactions contemplated by the Agreement and Plan of Merger, dated as of April 26, 2021 (as it may be amended from time to time, the “Merger Agreement”), by and among Holdings, Grace, and Gibraltar Merger Sub Inc., a wholly-owned subsidiary of Holdings (“Merger Sub”), pursuant to which Merger Sub will be merged with and into Grace with Grace surviving the merger as a wholly-owned subsidiary of Holdings (the “Merger”).

Holdings, in its sole discretion, may modify or terminate the Exchange Offers and may extend the Early Tender Date (as defined herein), Expiration Date (as defined herein) or any payment date with respect to the Exchange Offers, subject to applicable law. Any such modification, termination or extension by Holdings will automatically modify, terminate or extend the corresponding Consent Solicitation, as applicable.

Holders who validly tender their Existing Grace Notes at or prior to 5:00 p.m., New York City time, on August 16, 2021, unless extended (the “Early Tender Date”), will be eligible to receive, on the settlement date, the applicable Total Exchange Consideration as set forth in the table above, which includes the applicable Early Tender Premium as set forth in the table above, for all such Existing Grace Notes that are accepted. Holders who validly tender their Existing Grace Notes after the Early Tender Date but prior to 12:01 a.m., New York City time, on August 31, 2021, unless extended (the “Expiration Date”), will not be eligible to receive the applicable Early Tender Premium and, accordingly, will be eligible to receive, on the settlement date, only the applicable Exchange Consideration as set forth in the table above, for all such Existing Grace Notes that are accepted. The settlement date will be promptly after the Expiration Date and is expected to be within three business days after the Expiration Date. The Settlement Date is expected to occur concurrently with the consummation of the Merger; as such, the Expiration Date is expected to be extended to correspond to the timing of the consummation of the Merger.

Morgan and Citigroup to act as Solicitation Agents in connection with the Consent Solicitations.
