Explanatory Note: This Amendment No. 7 (this “Amendment”) filed by Marathon Petroleum Corporation (“MPC”), MPC Investment LLC (“MPC Investment”), MPLX Logistics Holdings LLC (“MPLX Logistics”), MPLX Holdings Inc. (“MPLX Holdings”) and MPLX GP LLC (“MPLX GP”) amends and supplements the statement on Schedule 13D concerning the common units representing limited partner interests (“MPLX Common Units”) in MPLX LP (the “Issuer”) filed on December 3, 2014 and as amended on December 12, 2014, August 19, 2015, December 7, 2015, April 4, 2016, March 6, 2017 and September 1, 2017 (the “Schedule 13D”). The Schedule 13D is not modified except as specifically provided herein. Any terms capitalized but not defined herein shall have the same meaning as defined in the Schedule 13D.
Item 1.
Security and Issuer
No changes to this Item.
Item 2.
Identity and Background
Item 2 of the Schedule 13D is hereby supplemented as follows:
The information required by subparagraphs (a), (b), (c) and (f) of this Item with respect to the directors and executive officers of the Reporting Persons is set forth on Schedule I attached hereto and is incorporated herein by reference.
Item 3.
Source and Amount of Funds or Other Consideration
No changes to this Item.

Item 4.
Purpose of Transaction
No changes to this Item.

Item 5.
Interest in Securities of the Issuer
Item 5 of the Schedule 13D is hereby amended and supplemented as follows:
(a) Items 11 and 13 of each Cover Page state the aggregate number and percentage of MPLX Common Units beneficially owned by the applicable Reporting Persons. Without giving effect to the MPLX Common Units to be issued in connection with the GP/IDR Restructuring (defined in Item 6), MPLX Logistics beneficially owns 66,546,319 MPLX Common Units, MPLX Holdings beneficially owns 28,627,587 MPLX Common Units and MPLX GP beneficially owns 22,916,917 MPLX Common Units, representing in the aggregate, approximately 29.0% of the MPLX Common Units issued and outstanding, based upon 407,068,878 MPLX Common Units issued and outstanding as of December 15, 2017, as reported by the Issuer to the Reporting Persons. MPC Investment owns all of the membership interests in MPLX Logistics and MPLX GP and all of the shares of stock of MPLX Holdings. MPC owns all of the membership interests in MPC Investment. Accordingly, MPC and MPC Investment both may be deemed to indirectly beneficially own the MPLX Common Units directly held by MPLX Logistics, MPLX Holdings and MPLX GP. The members of the board of directors of MPC are listed on Schedule I to this Amendment. No individual member of the board of directors of MPC is deemed to hold any beneficial ownership in the MPLX Common Units held by MPLX Logistics, MPLX Holdings or MPLX GP.
(b) The information provided in Item 5(a) of this Amendment and in Items 7 through 11 of the cover pages is incorporated herein by reference.
(c) Except as set forth herein, MPLX Logistics, MPLX Holdings and MPLX GP have not effected any transactions in the MPLX Common Units within the past 60 days. None of MPC, MPC Investment nor any person listed on Schedule I has effected any transactions in the MPLX Common Units within the past 60 days except as set forth in Schedule I.





(d) None of MPC, MPC Investment, MPLX GP, MPLX Holdings nor MPLX Logistics has any knowledge of any other person having the right to receive or the power to direct the receipt of distributions from, or the proceeds from the sale of, the MPLX Common Units held in the name of MPLX Logistics, MPLX Holdings or MPLX GP and reported herein.
(e) Not applicable.
Item 6.
Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer.
Item 6 of the Schedule 13D is hereby supplemented as follows:
On December 15, 2017, the Issuer entered into a Partnership Interests Restructuring Agreement  (the “Partnership Interests Restructuring Agreement”) with MPLX GP, the general partner of the Issuer, pursuant to which the MPLX incentive distribution rights (“IDRs”) held by MPLX GP will be cancelled and the two percent general partner interest in the Issuer held by MPLX GP will be converted into a non-economic general partner interest in the Issuer in exchange for 275,000,000 MPLX Common Units to be issued to MPLX GP (together, the “GP/IDR Restructuring”).

Subject to the terms and conditions of the Partnership Interests Restructuring Agreement, simultaneously with the closing of the GP/IDR Restructuring, MPLX GP will amend and restate the Third Amended and Restated Agreement of Limited Partnership of MPLX, dated as of October 31, 2016, as amended, to reflect the GP/IDR Restructuring. Pursuant to the Partnership Interests Restructuring Agreement, MPLX GP has agreed to waive a portion of the fourth quarter 2017 distributions that would otherwise be payable on the MPLX Common Units issued to MPLX GP as part of the GP/IDR Restructuring to the extent such distributions are in excess of the amount of fourth quarter 2017 distributions MPLX GP would have received with respect to its two percent general partner interest and IDRs absent the GP/IDR Restructuring.

The Partnership Interests Restructuring Agreement contains representations, warranties and covenants considered customary for an agreement of this type. The closing of the GP/IDR Restructuring is expected to occur on February 1, 2018 subject to customary closing conditions and the closing of the contribution to the Issuer of MPLX Refining Logistics LLC and MPLX Fuels Distribution LLC pursuant to the Membership Interests Contribution Agreement previously reported on a Current Report on Form 8-K filed by the Issuer on November 13, 2017.

The foregoing description of the Partnership Interests Restructuring Agreement is not complete and is qualified in its entirety by reference to the full text of the Partnership Interests Restructuring Agreement, which is filed as Exhibit 99.1 hereto, and incorporated herein by reference.
