Harvest Operations Announces Extension of Early Tender Time for Exchange Offer and Consent Solicitation

CALGARY, ALBERTA--(Marketwired - May 30, 2016) - Harvest Operations Corp. ("Harvest") today announced an amendment to its previously announced offer to exchange (the "Exchange Offer") any and all of its outstanding 6⁷/₈% Senior Notes due 2017 (the "Old Notes") for new 2.33% Guaranteed Notes due 2021 (the "New Notes") issued by Harvest and unconditionally and irrevocably guaranteed (such guarantee, the "Guarantee") by Korea National Oil Corporation ("KNOC") and related consent solicitation (the "Consent Solicitation") to adopt amendments to the indenture governing the Old Notes, which include eliminating certain of the covenants therein

The Exchange Offer and Consent Solicitation are being made pursuant to the terms and subject to the conditions set forth in the offering memorandum and consent solicitation statement dated May 16, 2016 (as amended or supplemented from time to time, the "Offering Memorandum") and the related letter of transmittal, and where applicable, the Canadian Private Placement Memorandum.

To encourage additional Eligible Holders (defined below) to tender their Old Notes, Harvest is extending the previously announced "Early Tender Time" of 5:00 p.m., New York City time on May 27, 2016 to 11:59 p.m., New York City time, on June 13, 2016, which is also the previously announced "Expiration Time." Accordingly, Eligible Holders who validly tender their Old Notes prior to the Expiration Time will be eligible to receive the previously announced "Total Exchange Consideration" of $900 principal amount of New Notes for each $1,000 principal amount of Old Notes accepted for exchange.

All other terms and conditions of the Exchange Offer and Consent Solicitation remain unchanged.

The previously announced withdrawal deadline for the Exchange Offer and Consent Solicitation has now passed and all Old Notes tendered pursuant to the Exchange Offer and Consent Solicitation may not be withdrawn.

The settlement date for the Exchange Offer and Consent Solicitation will be promptly following the Expiration Time and is expected to be within three business days after the Expiration Time.

The Exchange Offer and Consent Solicitation are subject to conditions, including a requirement, unless waived by Harvest, that it receives consents to the Proposed Amendments from holders of a majority of the outstanding principal amount of the Old Notes. Currently, the conditions to the Exchange Offer and Consent Solicitation have not been satisfied. Accordingly, unless additional Old Notes are tendered prior to the Expiration Time, Harvest will have no obligation to consummate the Exchange Offer. Harvest does not intend to waive the conditions to the Exchange Offer, although it reserves the right to do so.
