Item 1.01 Entry into a Material Definitive Agreement

On May 27, 2016, Western Refining, Inc. (the “Company”) and certain of its subsidiaries entered into the third amendment (the “Term Loan Amendment”) to the term loan credit agreement (the “Term Loan Credit Agreement”) among the Company, the lenders signatory thereto and Bank of America, N.A., as Administrative Agent and acknowledged by the Guarantors named therein.

The Term Loan Amendment amended the Term Loan Credit Agreement by, among other things, (i) permitting additional dividend, stock buyback and other “Restricted Payment” capacity in an amount of up to $200 million, (ii) establishing a new basket for making additional dividends, stock buybacks and other “Restricted Payments” in an amount equal to 50% of the net cash proceeds of certain asset sales to affiliates so long as the other 50% of net cash proceeds are offered to the lenders under the Term Loan Credit Agreement to prepay the term loans, (iii) providing that equity interests in any subsidiary that is a master limited partnership qualify as “replacement assets” for purposes of the asset sale mandatory prepayment, (iv) providing that the $200 million of incremental term loan capacity may be used to incur additional term loans or bonds secured on a pari passu basis and (v) increasing, immediately upon consummation of the purchase by the Company, directly or indirectly, of 100% of the equity of Northern Tier Energy LP (the “NTI Acquisition Trigger”), the incremental term loan capacity from $200 million to $700 million. In addition, (a) the applicable interest rate on the loans under the Term Loan Credit Agreement was increased from (x) the LIBOR Rate plus 3.50% or the Base Rate plus 2.50%, as applicable, to (y) the LIBOR Rate plus 4.25% or the Base Rate plus 3.25%, as applicable, (b) following the NTI Acquisition Trigger, the Company will be required to pledge as security 100% of the equity interests it owns in NT InterHoldCo LLC (“NTI Holdco”) and (c) following the NTI Acquisition Trigger, the ability of NTI Holdco and its subsidiaries to incur indebtedness will be limited as more fully set forth in the Term Loan Amendment.

On May 27, 2016, the Company and certain of its subsidiaries also entered into the second amendment (the “Revolving Credit Amendment”) to the third amended and restated revolving credit agreement (the “Existing Revolving Credit Agreement”) among the Company, the other persons party thereto as Guarantors, the lenders signatory thereto and Bank of America, N.A., as Administrative Agent.

The Revolving Credit Amendment amended the Existing Revolving Credit Agreement by, among other things, (i) permitting the Company to incur up to $500 million of additional secured indebtedness secured on a pari passu basis with the loans under the Term Loan Credit Agreement (in the form of incremental term loans or bonds secured on a pari passu basis with the term loans) beyond what was permitted under the Existing Revolving Credit Agreement and (ii) modifying several triggers and thresholds based on borrowing availability under the Revolving Credit Agreement.

The above descriptions do not purport to be a complete statement of the parties’ rights and obligations under the Revolving Credit Amendment and Term Loan Amendment.

The Revolving Credit Amendment and Term Loan Amendment are filed as Exhibit 10.1 and 10.2, respectively, to this Form 8-K. This description of the terms of the Revolving Credit Amendment and Term Loan Amendment are each qualified in their entirety by reference to such exhibits.

Certain of the lenders under the Revolving Credit Amendment and Term Loan Amendment and their respective affiliates have pre-existing relationships with the Company, including the performance of investment banking, commercial banking and advisory services for the Company, from time to time, for which such lenders have received customary fees and expenses.
