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.
