7.	Long-Term Debt

On March 6, 2024, Midstream entered into the Sixth Amendment to Credit Agreement and related Promissory Notes on the non-revolving credit facility. The Sixth Amendment revised the interest rate from Term SOFR plus 2.00% to Term SOFR plus 2.00% subject to adjustment to Term SOFR plus 1.75% and Term SOFR plus 1.55% upon meeting certain milestones. The Sixth Amendment also consolidated the Promissory Notes to one Promissory Note with one lender, increased the available non-revolving credit facility to $25 million, and extended the maturity date to December 31, 2025. All other terms and requirements remained unchanged.

On May 2, 2024, Midstream established a new $9 million revolving credit facility. The interest rate on the borrowings under the facility is Daily Simple SOFR plus 2.215%; the arrangement included a 0.40% upfront fee and 0.125% unused line fee. The facility matures on May 2, 2026.

On May 29, 2024, Midstream paid in full the $9 million note payable that was set to mature June 1, 2024 with proceeds from the new credit facility.

On March 6, 2024, Midstream amended and restated its $8 million Term Note. The amendment suspended quarterly principal payments beginning April 1, 2024 through January 1, 2025. Principal payments began again on April 1, 2025. All other terms and requirements of the Term Note were retained. The interest rate swap related to the $8 million Term Note was not amended on March 6, 2024.
