Item 5.03 Amendments to Articles of Incorporation or Bylaws; Change in Fiscal Year.

On January 23, 2014 (the “Effective Date”), Par Petroleum Corporation (the “Company”) filed a Certificate of Amendment (the “Charter Amendment”) to its Amended and Restated Certificate of Incorporation to implement a one-for-ten (1:10) reverse stock split (the “Reverse Stock Split”) of its issued and outstanding common stock, par value $0.01 per share (the “Common Stock”). The Company filed a definitive information statement on Schedule 14C on December 31, 2013, and the Charter Amendment was approved by the requisite stockholders of the Company by written consent effective December 26, 2013.

As a result of the Reverse Stock Split, every ten pre-split shares of Common Stock issued prior to the Effective Date will be exchanged for one post-split share of Common Stock, with fractional shares paid in cash at an amount equal to the product obtained by multiplying (a) the closing price of the Common Stock as reported on the OTCQB Marketplace on the Effective Date, by (b) the fraction of one share owned by the stockholder (the “Fractional Share Cash Payments”). Further, the number of shares of Common Stock issued and outstanding will be reduced from approximately 301,141,520 on the Effective Date to approximately 30,114,352. The number of authorized shares of Common Stock will remain at 500,000,000 and the par value of the Common Stock will remain at $0.01 per share.

The foregoing summary is qualified in its entirety by reference to the full text of the Charter Amendment, which is filed with this Current Report on Form 8-K as Exhibit 3.1 and is incorporated herein by reference.

Item 7.01 Regulation FD Disclosure.

On the Effective Date, the Company issued a press release announcing the completion of the Reverse Stock Split. The press release is attached hereto as Exhibit 99.1 and is incorporated herein by reference.

In accordance with General Instructions B.2 and B.6 of Form 8-K, the foregoing information, including Exhibit 99.1, shall not be deemed “filed” for the purposes of Section 18 of the Securities Exchange Act of 1934 or otherwise subject to the liabilities of that section, nor shall such information and Exhibit 99.1 be deemed incorporated by reference in any filing under the Securities Act of 1933 or the Exchange Act, except as shall be expressly set forth by specific reference in such a filing.

Item 8.01 Other Events

On the Effective Date and in connection with the consummation of the Reverse Stock Split, the Company and certain of its subsidiaries (the “Guarantors”) entered into an Eleventh Amendment (the “Eleventh Amendment”) to Delayed Draw Term Loan Credit Agreement (as amended from time to time, including the Eleventh Amendment, the “Credit Agreement”) with Jefferies Finance LLC, as administrative agent for ZCOF Par Petroleum Holdings, L.L.C (the “Lender”), pursuant to which the Lender consented to the Fractional Share Cash Payments.

The foregoing summary is qualified in its entirety by reference to the full text of the Eleventh Amendment, which is filed with this Current Report on Form 8-K as Exhibit 10.1 and is incorporated herein by reference.
