WNRL issued 628,224 common units to SPPR, representing $15 million of common units, based upon the volume-weighted average price per unit for the 20-day trading period ended September 6, 2016.

In addition, WNRL has agreed, subject to certain exceptions, to assume the liabilities arising from the ownership and operation of the Contributed Assets and has agreed to indemnify Western with respect to such assumed liabilities.

The consummation of the Transaction is subject to the satisfaction of certain closing conditions, including, among other things, the absence of legal impediments prohibiting the Transaction, the absence of a material adverse effect on the Contributed Assets or the financial condition, liabilities or results of operations of the business relating to the Contributed Assets and the receipt by Western from an independent appraiser of a written certificate stating that the release of the Contributed Assets under the NTI Indenture (as defined in the Contribution Agreement) will not impair the security under the NTI Indenture. There is no assurance that all of the conditions to the consummation of the Transaction will be satisfied. The Partnership currently expects the Transaction to close on or about September 15, 2016.
