Heartland Share Purchase and Subscription Agreement On January 17, 2020 (the “Heartland Closing Date”), Vertex Operating, Tensile-Heartland, and solely for the purposes of the Heartland Guaranty (defined below), the Company, and HPRM LLC, a Delaware limited liability company, which entity was formed as a special purpose vehicle in connection with the transactions, described in greater detail below (“Heartland SPV”), entered into a Share Purchase and Subscription Agreement (the “Heartland Share Purchase”). Prior to entering into the Heartland Share Purchase, the Company transferred 100% of the ownership of Vertex Refining OH, LLC, its indirect wholly-owned subsidiary (“Vertex OH”) to Heartland SPV in consideration for 13,500 Class A Units, 13,500 Class A-1 Preferred Units and 11,300 Class B Units of Heartland SPV and immediately thereafter contributed 248 Class B Units to the Company’s wholly-owned subsidiary, Vertex Splitter Corporation, a Delaware corporation (“Vertex Splitter”), as a contribution to capital. Vertex OH owned the Company’s Columbus, Ohio, Heartland facility, which produces a base oil product that is sold to lubricant packagers and distributors. Pursuant to the Heartland Share Purchase, Vertex Operating sold Tensile-Heartland the 13,500 Class A Units and 13,500 Class A-1 Preferred Units of Heartland SPV in consideration for $13.5 million. Also, on the Heartland Closing Date, Tensile-Heartland purchased 7,500 Class A Units and 7,500 Class A-1 Units in consideration for $7.5 million (less the expenses of Tensile-Heartland in connection with the transaction) directly from Heartland SPV. The approximate $7.5 million purchase amount and future free cash flows from the operation of Heartland SPV are planned to be available for investments at the Heartland facility to increase self-collections, maximize the throughput of the refinery, enhance the quality of the output and complete other projects. Concurrently with the closing of the transactions described above, and pursuant to the terms of the Heartland Share Purchase, the Company, through Vertex Operating, purchased 1,000 newly issued Class A Units from MG SPV at a cost of $1,000 per unit ($1 million in aggregate). The Heartland Share Purchase provides Tensile-Heartland an option, exercisable at its election, any time, subject to the terms of the Heartland Share Purchase, to purchase up to an additional 7,000 Class A-2 Preferred Units at a cost of $1,000 per Class A-2 Preferred Unit from Heartland SPV. The Heartland SPV is currently owned 35% by Vertex Operating and 65% by Tensile-Heartland. Heartland SPV is managed by a five-member Board of Managers, of which three members are appointed by Tensile-Heartland and two are appointed by the Company. The Class A Units held by Tensile-Heartland are convertible into Class B Units as provided in the Limited Liability Company Agreement of Heartland SPV (the “Heartland Company Agreement”), based on a conversion price (initially one-for-one) which may be reduced from time to time if new Units of Heartland SPV are issued and will automatically convert into Series A Units upon certain events described in the Heartland Company Agreement. The Class A-1 and A-2 Preferred Units (“Class A Preferred Units”), which are 100% owned by Tensile-Heartland, accrue a 22.5% per annum preferred return subject to terms of the Heartland Company Agreement (the “Class A Yield”). Additionally, the Class A Unit holders (common and preferred) may force Heartland SPV to redeem the outstanding Class A Units at any time on or after the earlier of (a) the fifth anniversary of the Closing Date and (ii) the occurrence of a Heartland Triggering Event (defined below)(a “Heartland Redemption”). The cash purchase price for such redeemed Class A Unit will be the greater of (y) the fair market value of such units (without discount for illiquidity, minority status or otherwise) as determined by a qualified third party agreed to in writing by a majority of the holders seeking Heartland Redemption and Vertex Operating (provided that Vertex Operating still owns Class B Units on such date) and (z) the original per-unit price for such Class A Units plus fifty percent (50%) of the aggregate capital invested by the Class A Unit holders through such Heartland Redemption date. “Heartland Triggering Events” include (a) any termination of the Administrative Services Agreement pursuant to its terms and/or any material breach by us of the environmental remediation and indemnity agreement, (b) any dissolution, winding up or liquidation of the Company, Vertex Operating or any significant subsidiary of Vertex Operating, (c) any sale, lease, license or disposition of any material assets of the Company, Vertex Operating or any significant subsidiary of Vertex Operating, or (d) any transaction or series of related transactions (whether by merger, exchange, contribution, recapitalization, consolidation, reorganization, combination or otherwise) involving the Company, Vertex Operating or any significant subsidiary of Vertex Operating, the result of which is that the holders of the voting securities of the relevant entity as of the Closing Date are no longer the beneficial owners, in the aggregate, after giving effect to such transaction or series of transactions, directly or indirectly, of more than fifty percent (50%) of the voting power of the outstanding voting securities of the entity, subject to certain other requirements set forth in the Heartland Company Agreement. In the event that Heartland SPV fails to redeem such Class A Units within 180 days after a redemption is triggered, the Class A Yield is increased to 25% until such time as such redemption is completed (with such increase being effective back to the original date of a notice of redemption). In addition, in such event, the Class A Unit holders may cause Heartland SPV to initiate a process intended to result in a sale of Heartland SPV. Distributions of available cash of Heartland SPV pursuant to the Heartland Company Agreement (including pursuant to liquidations of Heartland SPV), subject to certain exceptions set forth therein, are to be made (a) first, to the holders of the Class A Preferred Units, in amount equal to the greater of (A) the aggregate unpaid Class A Yield and (B) an amount equal to fifty percent (50%) of the aggregate capital invested by the Class A Preferred Unit holders (initially Tensile-Heartland)(such aggregate capital invested by the Class A Preferred Unit holders, the “Heartland Invested Capital”, which totaled approximately $21 million as of the Heartland Closing Date, subject to adjustment as provided in the Heartland Share Purchase), less prior distributions (such greater amount of (A) and (B), the “Class A Preferred Priority Distributions”); (b) second, the Class A Preferred Unitholders, together as a separate and distinct class, are entitled to receive an amount equal to the aggregate Heartland Invested Capital; (c) third, the Class B Unitholders (other than Class B Unitholders which received Class B Units upon conversion of Class A Preferred Units), together as a separate and distinct class, are entitled to receive all or a portion of any distribution equal to the sum of all distributions made under sections (a) and (b) above; and (d) fourth, to the holders of Units who are eligible to receive such distributions in proportion to the number of Units held by such holders. Variable interest entity Per ASC 810-10-25-38A and 38B, a reporting entity shall be deemed to have a controlling financial interest in a variable interest entity (VIE) if it has both of the following characteristics: the power to direct the activities of a VIE that most significantly impact the VIE’s economic performance, and the obligation to absorb losses of the VIE that could potentially be significant to the VIE or the right to receive benefits from the VIE that could potentially be significant to the VIE. The Company determined that since substantially all of the activities of Heartland SPV (i.e., the VIE) are conducted on behalf of a single VIE holder, and that the Company is the primary beneficiary of the VIE. Accordingly, Heartland SPV should be consolidated in the Company’s consolidated financial statements. Accordantly, the only impact to the consolidated financial position and results of operations will be to present the 65% owned by Tensile-Heartland in non-controlling interest.
