We have entered into a credit facility with Royal Bank of Canada, as administrative agent and collateral agent, and the lenders party thereto, as amended through the date of the Twelfth Amendment to Third Amended and Restated Credit Agreement, dated as of August 20, 2021 (the “Credit Agreement”). The Credit Agreement provides a quarterly amortizing term loan of $65.0 million (the “Term Loan”) and a maximum revolving credit amount of $5.0 million (the “Revolving Loan”). The Credit Agreement matures on September 30, 2023. Borrowings under the Credit Agreement are secured by various mortgages of midstream properties that we own as well as various security and pledge agreements among us, certain of our subsidiaries and the administrative agent.

Borrowings under the Credit Agreement are available for limited direct investment in midstream properties, acquisitions, and working capital and general business purposes. The Credit Agreement has a sub-limit of up to $2.5 million which may be used for the issuance of letters of credit. As of March 31, 2022, we had approximately $47.7 million of debt outstanding, consisting of approximately $46.2 million under the Term Loan and approximately $1.5 million under the Revolving Loan. We are required to make mandatory amortizing payments of outstanding principal on the Term Loan of (i) $3.0 million per fiscal quarter commencing with the quarter

ending December 31, 2021, and (ii) $2.0 million per fiscal quarter commencing with the quarter ending March 31, 2023. As of March 31, 2022, we have met our mandatory amortizing payments of outstanding principal on the Term Loan through June 30, 2022. The maximum revolving credit amount is $5.0 million, leaving us with approximately $3.5 million in unused borrowing capacity. There were no letters of credit outstanding under our Credit Agreement as of March 31, 2022.

At our election, interest for borrowings under the Credit Agreement are determined by reference to (i) the London Interbank Offered Rate (“LIBOR”) plus an applicable margin between 2.75% and 3.50% per annum based on net debt to EBITDA or (ii) a domestic bank rate (“ABR”) plus an applicable margin between 1.75% and 2.50% per annum based on net debt to EBITDA plus (iii) a commitment fee of 0.50% per annum based on the unutilized portion of the Revolving Loan. Interest on the borrowings for ABR loans and the commitment fee are generally payable quarterly. Interest on the borrowings for LIBOR loans are generally payable at the applicable maturity date.

The Credit Agreement contains various covenants that limit, among other things, our ability to incur certain indebtedness, grant certain liens, merge or consolidate, sell all or substantially all of our assets, make certain loans, acquisitions, capital expenditures and investments, and pay distributions to unitholders.

The Credit Agreement also includes customary events of default, including events of default relating to non-payment of principal, interest or fees, inaccuracy of representations and warranties when made or when deemed made, violation of covenants, cross-defaults, bankruptcy and insolvency events, certain unsatisfied judgments, loan documents not being valid and a change in control. A change in control is generally defined as the occurrence of one of the following events: (i) our existing general partner ceases to be our sole general partner or (ii) certain specified persons shall cease to own more than 50% of the equity interests of our general partner or shall cease to control our general partner. If an event of default occurs, the lenders will be able to accelerate the maturity of the Credit Agreement and exercise other rights and remedies.

At March 31, 2022, we were in compliance with the financial covenants contained in the Credit Agreement. We monitor compliance on an ongoing basis. If we are unable to remain in compliance with the financial covenants contained in our Credit Agreement or maintain the required ratios discussed above, the lenders could call an event of default and accelerate the outstanding debt under the terms of the Credit Agreement, such that our outstanding debt could become then due and payable. We may request waivers of compliance from the violated financial covenants from the lenders, but there is no assurance that such waivers would be granted.

We are required to make mandatory amortizing payments of the outstanding principal on the Term Loan and we expect these quarterly amortizing payments will be made from our operating cash flows and other capital resources. However, there can be no assurance that operations and other capital resources will provide cash in sufficient amounts to make these mandatory amortizing payments.

Debt Issuance Costs

As of March 31, 2022 and December 31, 2021, our unamortized debt issuance costs were approximately $0.7 million and $0.6 million, respectively. These costs are amortized to interest expense in our consolidated statements of operations over the life of our Credit Agreement. Amortization of debt issuance costs recorded during the three months ended March 31, 2022 and 2021 was approximately $0.1 million and $0.2 million, respectively.
