(c)

The principal business of Tesoro Refining and Tesoro Alaska is the refining and marketing of refined petroleum products.

Accordingly, MPLX GP is an indirect wholly owned subsidiary of MPC.
Item 3.
Source and Amount of Funds or Other Consideration
Item 3 of the Schedule 13D is hereby amended and supplemented as follows:
The information provided or incorporated by reference in Item 4 below is hereby incorporated by reference into this Item 3:
On July 30, 2019, MPLX MAX LLC, a wholly-owned subsidiary of MPLX, merged with and into ANDX (the “ANDX Merger”) with ANDX surviving the merger as a wholly owned subsidiary of MPLX. In connection with the ANDX Merger, each common unit representing limited partner interests in ANDX (“ANDX Common Units”) was converted into the right to receive MPLX Common Units. Following the ANDX Merger, WRSW is the record holder of 69,763,859 MPLX Common Units, representing approximately 6.6% of outstanding MPLX Common Units, and TLGP is the record holder of 91,531,747 MPLX Common Units, representing approximately 8.7% of outstanding MPLX Common Units. Tesoro Refining, Tesoro Alaska and WRSW together own 100% of TLGP and may be deemed to beneficially own MPLX Common Units held by TLGP. WRSW is a wholly owned subsidiary of Giant, which is a wholly owned subsidiary of Western Refining, which is a wholly owned subsidiary of Andeavor, which is a wholly owned subsidiary of MPC. As a result, MPC, Andeavor, Western Refining and Giant may be deemed to beneficially own MPLX Common Units through their ownership in WRSW.
Item 4.
Purpose of the Transaction
Item 4 of the Schedule 13D is hereby amended and supplemented as follows:
The information previously provided in response to Item 4 is hereby amended and supplemented by adding the following:
On July 30, 2019, the ANDX Merger was completed. Subject to the terms and conditions set forth in the Merger Agreement, at the effective time of the ANDX Merger, each outstanding ANDX Common Unit, other than any ANDX Common Unit held by TLGP and WRSW, was converted into the right to receive 1.135 MPLX Common Units such exchange ratio, the “Exchange Ratio”), and each ANDX Common Unit held by TLGP and WRSW was converted into the right to receive 1.0328 MPLX Common Units, in each case, in consideration for each ANDX Common Unit that such holder owned immediately prior to the effective time of the ANDX Merger. Additionally, each 6.875% Series A Fixed-to-Floating Rate Cumulative Redeemable Perpetual Preferred Unit, liquidation preference $1,000 per unit, representing a limited partner interest in ANDX (each, an “ANDX Series A Preferred Unit”) issued and outstanding immediately prior to the effective time of the ANDX Merger was converted into the right to receive a new Series B Preferred Unit representing substantially equivalent limited partnership interests in MPLX (the “MPLX Series B Preferred Units”). The MPLX Series B Preferred Units are a new class of units in MPLX that are pari passu with MPLX’s existing Series A Convertible Preferred Units with respect to distribution rights and rights upon liquidation and have substantially equivalent preferences, rights, powers, duties and obligations that the ANDX Series A Preferred Units had immediately prior to the closing of the ANDX Merger.
At the effective time of the ANDX Merger, each phantom unit issued under ANDX’s 2011 Long-Term Incentive Plan, as amended and restated, and the Western Refining Logistics, LP 2013 Long-Term Incentive Plan (the “ANDX Phantom Units”), whether vested or unvested, other than any ANDX Phantom Unit that was held by a non-employee director of ANDX GP (each, an “ANDX Director Phantom Unit”), were automatically converted into a phantom unit denominated in MPLX Common Units (each, a “Converted MPLX Phantom Unit”). The number of ANDX Common Units subject to the ANDX Phantom Units immediately prior to the effective time of the ANDX Merger were converted into a number of MPLX Common Units subject to the Converted MPLX Phantom Units based on the Exchange Ratio (rounded down to the nearest whole number). ANDX Director Phantom Units were generally converted into the right to receive a cash payment equal to the number of ANDX Common Units subject to such ANDX Director Phantom Unit multiplied by the product of the Exchange Ratio and the average





of the volume weighted average price per unit of MPLX Common Units on the New York Stock Exchange on each of the ten consecutive trading days ending with the complete trading day immediately prior to the closing of the ANDX Merger.

Additionally, as a result of the ANDX Merger, each ANDX TexNew Mex Unit issued and outstanding immediately prior to the effective time of the ANDX Merger was converted into a right for WRSW, as the holder of all such units, to receive a unit representing a substantially equivalent special limited partner interest in MPLX (the “MPLX TexNew Mex Units”). By virtue of the conversion, all ANDX TexNew Mex Units were cancelled and ceased to exist as of the effective time of the ANDX Merger. The MPLX TexNew Mex Units are a new class of units in MPLX substantially equivalent to the ANDX TexNew Mex Units, including substantially equivalent powers, preferences, rights to distributions and relative participating, optional or other special rights and the qualifications, limitations or restrictions thereon, that the ANDX TexNew Mex Units had immediately prior to the closing of the ANDX Merger. As a result of the ANDX Merger, the ANDX Special Limited Partner Interest outstanding immediately prior to the effective time of the ANDX Merger was converted into a right for WRSW, as the holder of all such interest, to receive a substantially equivalent special limited partner interest in MPLX (the “MPLX Special Limited Partner Interest”). By virtue of the conversion, the ANDX Special Limited Partner Interest was cancelled and ceased to exist as of the effective time of the ANDX Merger.

Item 5.
