On October 27, 2021, Option Care Health, Inc. issued $500 million in aggregate principal amount of 4% senior notes due 2029 at an issue price of 100.000% (the Offering), under an indenture dated as of October 27, 2021 (the Indenture), among the company, the guarantors party thereto and Ankura Trust Company, LLC, as trustee, registrar and paying agent. On October 27, 2021, the company also entered into (i) an agreement to amend and restate its existing first lien term loan B facility to, among other things, provide for $600 million aggregate principal amount of refinancing term loans and extend its maturity to 2028 (the New First Lien Term Loan Facility), and (ii) an agreement to amend its existing asset-based lending revolving credit facility to, among other things, extend its maturity to 2026, decrease the applicable margin and align with the changes to the New First Lien Term Loan Facility. The company used the proceeds from the Offering, together with the New First Lien Term Loan Facility and cash on hand, to refinance borrowings outstanding under its existing first lien term loan B facility, and to pay fees and expenses in connection therewith and with the Offering. The Notes bear interest at a rate of 4.375% per annum payable semi-annually in arrears on October 31 and April 30 of each year, commencing April 30, 2022. The Notes are general senior unsecured obligations of the company and rank equally in right of payment with any of the company's existing and future senior indebtedness, including obligations under the company's Senior Secured Facilities, and senior in right of payment to any future subordinated indebtedness of the company. The Notes are effectively subordinated to any existing and future secured indebtedness of the company, to the extent of the value of the assets securing such indebtedness (including borrowings under the Senior Secured Facilities). The Notes are guaranteed on a senior unsecured basis by each of existing and future wholly-owned domestic restricted subsidiaries (the Guarantors) that incurs or guarantees debt under the New First Lien Term Loan Facility (the Guarantees), subject to certain exceptions. The Notes and the related Guarantees are structurally subordinated to any existing and future indebtedness and other liabilities, including preferred stock, of the company's non-guarantor subsidiaries.
