The company may also request up to two one-year extensions of the maturity date with majority lender approval.

The agreement includes sub-facilities for swing-line loans up to $300 million and letters of credit up to $2 billion, which may be increased to $3 billion upon receipt of additional commitments.

Commitment fees range from 10 to 25 basis points annually on unused commitments, depending on Marathon Petroleum's credit ratings. Interest rates are based on either Term SOFR plus applicable margin or an Alternate Base Rate plus margin ranging from 0 to 75 basis points annually.
