On December 20, 2021, Crestwood Midstream Partners LP entered into a Third Amended and Restated Credit Agreement (the “ Midstream Credit Agreement”) by and among Midstream, as borrower, the lenders party thereto, Wells Fargo Bank, National Association, as administrative agent and collateral agent (“ Wells Fargo”), and certain other agents party thereto. The Midstream Credit Agreement provides for a five-year $1.50 billion revolving credit facility (the “ Revolving Credit Facility”) the proceeds of which may be used for general corporate purposes. The Revolving Credit Facility has an automatic upsizing feature from $1.25 billion to $1.50 billion upon closing of the previously announced transactions set forth in the Agreement and Plan of Merger, dated as of October 25, 2021, by and among Oasis Midstream Partners, LP, OMP GP LLC, Crestwood Equity Partners LP, Project Falcon Merger Sub LLC, Project Phantom Merger Sub LLC, and Crestwood Equity GP LLC and the satisfaction of certain other conditions set forth in the Midstream Credit Agreement. The Revolving Credit Facility has an accordion feature that will allow Midstream to increase the available borrowings under the facility by up to $350 million, subject to the lenders agreeing to satisfy the increased commitment amounts under the Revolving Credit Facility and the satisfaction of certain other conditions. In addition, the Revolving Credit Facility includes a sub-limit up to $25 million for same-day swing line advances and a sub-limit of up to $350 million for letters of credit. The Midstream Credit Agreement contains customary covenants and restrictive provisions, including maintenance of (i) a consolidated total leverage ratio of not more than 5.50 to 1.00, (ii) an interest coverage ratio of not less than 2.50 to 1.00 and (iii) a senior secured leverage ratio of not more than 3.50 to 1.00. Borrowings under the Revolving Credit Facility are generally secured by substantially all the assets of Midstream and its subsidiary guarantors, and loans thereunder (other than swing line loans) bear interest at Midscream’s option at either: the Alternate Base Rate, which is defined as the highest of (i) the federal funds rate plus 0.50% per annum; (ii) Wells Fargo’s prime rate; or (iii) the Adjusted Term SOFR for a one-month tenor plus 1% per annum; plus a margin varying from 0.50% to 1.50% per annum depending on Midstream’s most recent consolidated total leverage ratio; or Adjusted Term SOFR (which is Term SOFR plus 0.10% per annum for 1-month interest periods, 0.15% for 3-month interest periods and 0.25% for 6-month interest periods) plus a margin varying from 1.50% to 2.50% per annum depending on Midstream’s most recent consolidated total leverage ratio. Swing line loans bear interest at the Alternate Base Rate as described above. The unused portion of the Revolving Credit Facility is subject to a commitment fee ranging from 0.30% to 0.50% per annum according to Midstream’s most recent consolidated total leverage ratio. Interest on Alternate Base Rate loans is payable quarterly, or if Adjusted Term SOFR applies, at certain intervals as selected by Midstream. The Midstream Credit Agreement also provides for certain representations, warranties and affirmative covenants and negative covenants customary for transactions of this type. The Midstream Credit Agreement provides that all obligations thereunder will, subject to certain terms and exceptions, be jointly and severally guaranteed by Midstream’s subsidiary guarantors described therein and by Crestwood Equity Partners LP (“ CEQP”) under an unsecured parent guaranty. The Midstream Credit Agreement provides that all obligations thereunder and the guarantees (other than CEQP’s guaranty) will be secured by a lien on all assets and a pledge of all of the capital stock of Midstream’s material domestic restricted subsidiaries subject to certain terms and exceptions.
