Even though the minimum participation amount had been satisfied, the early tender deadline was previously extended to 5:00 p.m., New York City time, on October 4, 2016 (the “Early Tender Date”).

The Exchange Offers are scheduled to expire at 11:59 p.m., New York City time, on October 12, 2016, unless extended (the “Expiration Date”). No tenders will be valid if submitted after the Expiration Date.

Withdrawal rights for the Exchange Offers expired as of 5:00 p.m., New York City time, on September 27, 2016 (the “Withdrawal Deadline”). Because the Withdrawal Deadline was not extended, holders of Old Notes who have previously tendered and not withdrawn their Old Notes or who tender their Old Notes after the Withdrawal Deadline, but prior to the Expiration Date, may not withdraw their tendered Old Notes.

As of 5:00 p.m., New York City time, on the Early Tender Date, the following principal amounts of the Old Notes have been validly tendered and not validly withdrawn:

As previously announced, the Exchange Offer for the 2019 Notes is conditioned upon a minimum of $200,000,000 aggregate principal amount outstanding of 2019 Notes being tendered (the “2019 Notes Minimum Amount”), and the 2019 Notes Minimum Amount has been satisfied. The Exchange Offer for the 2024 Notes is not conditioned upon any minimum amount of 2024 Notes being tendered. The Exchange Offers are subject to the satisfaction of certain customary conditions, in addition to the Aggregate Maximum Amount.

Subject to applicable law, the Issuers may (i) extend or otherwise amend the Expiration Date or (ii) increase the Aggregate Maximum Amount without reinstating withdrawal rights. Any additional extension or termination of the Exchange Offers will be followed as promptly as practicable by a public announcement thereof.

The original complete terms and conditions of the Exchange Offers are described in the Offer to Exchange, a copy of which is filed as an exhibit to the Form T-3 filed by the Issuers with the Securities and Exchange Commission (the “SEC”) on September 12, 2016.

None of the Issuers, the exchange agent, the information agent, the trustee or the administrative agent for the Old Notes or the New Secured Notes or their respective affiliates is making any recommendation as to whether or not holders should tender all or any portion of their Old Notes in the Exchange Offers.

The Exchange Offers are being made solely pursuant to the Offer to Exchange. The Issuers are relying on Section 3(a)(9) of the Securities Act of 1933, as amended (the “Securities Act”), to exempt the Exchange Offers from the registration requirements of the Securities Act. The Issuers have not and will not file a registration statement with the SEC under the Securities Act or any other federal or state securities laws with respect to the New Secured Notes, nor has the SEC or any state or foreign securities commission passed upon the fairness or merits of the Exchange Offers or upon the accuracy or adequacy of the information contained in, or incorporated by reference into, the Offer to Exchange or any related documents. This announcement is not an offer to purchase nor a solicitation of an offer to sell with respect to any securities. The Exchange Offers are not being made to holders of Old Notes in any jurisdiction in which the making or acceptance thereof would not be in compliance with the securities, blue sky or other laws of such jurisdiction.
