Sumitomo Mitsui Banking Corporation and The Toronto-Dominion Bank, New York Branch, as documentation agents, and the

other lenders and issuing banks that are parties thereto (the “New MPC Credit Agreement”).

The New MPC Credit Agreement replaces the previously effective 2022 MPC Credit Agreement (as defined below) and is

intended to be used for general corporate purposes. There were no borrowings outstanding under the 2022 MPC Credit

Agreement at the time of its termination, and as of the date hereof, there are no borrowings outstanding under the New MPC

Credit Agreement. As of March 31, 2026, MPC had $2.2 billion of cash and cash equivalents, including $1.5 billion of cash and

cash equivalents held by MPLX.

The New MPC Credit Agreement provides for a $5.0 billion unsecured revolving credit facility that matures on April 7, 2031. MPC

has an option to increase the aggregate commitments by up to an additional $1.0 billion, subject to, among other conditions, the

consent of the lenders whose commitments would be increased. In addition, MPC may request up to two one-year extensions of

the maturity date of the New MPC Credit Agreement subject to, among other conditions, the consent of lenders holding a

majority of the commitments, provided that the commitments of any non-consenting lenders will terminate on the then-effective

maturity date. The New MPC Credit Agreement includes sub-facilities for swing-line loans of up to $300.0 million and letters of

credit of up to $2.0 billion (which may be increased to up to $3.0 billion upon receipt of additional letter of credit issuing

commitments).

Commitment fees ranging from 10.0 basis points to 25.0 basis points per annum, depending on MPC’s credit ratings, accrue on

the unused commitments under the New MPC Credit Agreement. Borrowings under the New MPC Credit Agreement bear

interest, at MPC’s election, at either (i) the Term SOFR (as defined in the New MPC Credit Agreement) plus the applicable

margin, depending on MPC’s credit ratings, or (ii) the Alternate Base Rate (as defined in the New MPC Credit Agreement) plus

the applicable margin ranging from 0.0 basis points to 75.0 basis points per annum, depending on MPC’s credit ratings.

The New MPC Credit Agreement contains representations and warranties, affirmative and negative covenants and events of

default that MPC considers customary for an agreement of its nature and type, including a covenant that requires MPC to

maintain a ratio (expressed as a percentage) of Consolidated Net Debt (as defined in the New MPC Credit Agreement) to Total

Capitalization (as defined in the New MPC Credit Agreement) not to exceed 65% as of the last day of each fiscal quarter. If an

event of default exists under the New MPC Credit Agreement, the lenders may terminate the commitments thereunder and

require the immediate repayment of all outstanding borrowings and the cash collateralization of all outstanding letters of credit. In

addition to commitment fees and interest charges, MPC agreed to pay administrative fees, letter of credit fronting fees and other

customary fees and to reimburse certain expenses of the lenders and agents incurred in connection with the New MPC Credit

Agreement.

On April 7, 2026, MPLX LP, a Delaware master limited partnership sponsored by MPC (“MPLX”), entered into a $2.5 billion, five-

year Revolving Credit Agreement with Wells Fargo Bank, National Association, as administrative agent, each of Wells Fargo

Securities, LLC, JPMorgan Chase Bank, N.A., Barclays Bank PLC, BofA Securities, Inc., Citibank, N.A., Goldman Sachs Bank

Bank of Canada, Sumitomo Mitsui Banking Corporation and The Toronto-Dominion Bank, New York Branch, as documentation

agents, and the other lenders and issuing banks that are parties thereto (the “New MPLX Credit Agreement”).

The New MPLX Credit Agreement replaces the previously effective 2022 MPLX Credit Agreement (as defined below) and is

intended to be used for general partnership purposes. There were no borrowings outstanding under the 2022 MPLX Credit

Agreement at the time of its termination, and as of the date hereof, there are no borrowings outstanding under the New MPLX

Credit Agreement. As of March 31, 2026, MPLX had $1.5 billion of cash and cash equivalents.

The New MPLX Credit Agreement provides for a $2.5 billion unsecured revolving credit facility that matures on April 7, 2031.

MPLX has an option to increase the aggregate commitments by up to an additional $1.0 billion, subject to, among other

conditions, the consent of the lenders whose commitments would be increased. In addition, MPLX may request up to two one-

year extensions of the maturity date of the New MPLX Credit Agreement subject to, among other conditions, the consent of

lenders holding a majority of the commitments, provided that the commitments of any non-consenting lenders will terminate on

the then-effective maturity date. The New MPLX Credit Agreement includes sub-facilities for swing-line loans of up to $150.0

million and letters of credit of up to $150.0 million (which may be increased to up to $200.0 million upon receipt of additional letter

of credit issuing commitments).

Commitment fees ranging from 10.0 basis points to 25.0 basis points per annum, depending on MPLX’s credit ratings, accrue on

the unused commitments under the New MPLX Credit Agreement. Borrowings under the New MPLX Credit Agreement bear

interest, at MPLX’s election, at either (i) the Adjusted Term SOFR (as defined in the New MPLX Credit Agreement) plus the

applicable margin ranging from 100.0 basis points to 175.0 basis points per annum, depending on MPLX’s credit ratings, or (ii)

the Alternate Base Rate (as defined in the New MPLX Credit Agreement) plus the applicable margin ranging from 0.0 basis

points to 75.0 basis points per annum, depending on MPLX’s credit ratings.

The New MPLX Credit Agreement contains representations and warranties, affirmative and negative covenants and events of

default that MPLX considers customary for an agreement of its nature and type, including a covenant that requires MPLX’s ratio

of Consolidated Total Debt (as defined in the New MPLX Credit Agreement) to Consolidated EBITDA (as defined in the New

MPLX Credit Agreement) for the four prior fiscal quarters not to exceed 5.0 to 1.0 as of the last day of each fiscal quarter (or 5.5

to 1.0 during an Acquisition Period (as defined in the New MPLX Credit Agreement)). Consolidated EBITDA is subject to

adjustments for certain acquisitions completed and capital projects undertaken during the relevant period. In addition to

commitment fees and interest charges, MPLX agreed to pay administrative fees, letter of credit fronting fees and other customary

fees and to reimburse certain expenses of the lenders and agents incurred in connection with the New MPLX Credit Agreement.

Certain parties to the New MPC Credit Agreement and the New MPLX Credit Agreement have in the past performed, and may in

the future from time to time perform, investment banking, financial advisory, lending or commercial banking services for MPC or

MPLX and their subsidiaries and affiliates, for which they have received, and may in the future receive, customary compensation

and reimbursement of expenses.
