7. | Long-Term Debt
On November 1, 2021 Midstream entered into an unsecured promissory note in the principal amount of $8 million with an interest rate based on 30-day LIBOR plus 115 basis points maturing January 1, 2028. Related to this note, Midstream also entered into an interest rate swap agreement that effectively converts the variable rate note into a fixed rate instrument with an effective annual interest rate of 2.443%. The loan will convert into an installment loan with principal pay-down beginning in fiscal 2023. In addition, this note reduces the borrowing capacity defined by the Third Amendment to Credit Agreement and related Promissory Notes. The total borrowing capacity declined from $41 million to $33 million effective with the new promissory note. All other terms of the Third Amendment to Credit Agreement remain unchanged. On September 24, 2021, Roanoke Gas entered into a Loan Agreement ("Agreement") and an unsecured Delayed Draw Promissory Note in the principal amount of $10 million ("Promissory Note"). Under the provisions of the Agreement, Roanoke Gas will receive a first advance of $5 million on or about April 1, 2022 with the remaining $5 million to be received on or about October 1, 2022. The Promissory Note has an interest rate of 30-day LIBOR plus 100 basis points and a maturity date of October 1, 2028. The proceeds from this Promissory Note will be used to finance Roanoke Gas' infrastructure enhancement and replacement projects. Also, on September 24, 2021, Roanoke Gas entered into an interest rate swap agreement for $10 million corresponding to the term and draw provisions of the Agreement, which effectively converts the variable rate Promissory Note to a fixed instrument with an effective annual interest rate of 2.49%. On August 20, 2021, Roanoke Gas entered into an unsecured Delayed Draw Term Note in the principal amount of $15 million ("Term Note") with an interest rate of 1.20% above 30-day SOFR Average per annum maturing on August 20, 2026. In connection with the Term Note, Roanoke Gas also entered into the Sixth Amendment to its Credit Agreement ("Amendment"), which amends the original Credit Agreement with the corresponding bank dated March 31, 2016 and all subsequent amendments. The Amendment aligns the termination date and the maximum principal amount available under the Term Note and retains all other terms and requirements of prior credit agreements. The proceeds from this Term Note will be used to finance Roanoke Gas' infrastructure enhancement and replacement projects, as well as to refinance a portion of its existing debt. Also, on August 20, 2021, Roanoke Gas entered into an interest rate swap agreement for $15 million corresponding to the duration of the Term Note, which effectively converts the variable rate note to a fixed rate instrument with an effective annual interest rate of 2.00%. The Term Note funded in full on October 1, 2021. Long-term debt consists of the following:
