On May 24, 2021, the Partnership and our wholly owned subsidiary Delek Logistics Finance Corp. ("Finance Corp." and together with the Partnership, the "Issuers") issued $400.0 million in aggregate principal amount of 7.125% senior notes due 2028 (the "2028 Notes") at par, pursuant to an indenture with U.S. Bank, National Association as trustee. The 2028 Notes are general unsecured senior obligations of the Issuers and are unconditionally guaranteed jointly and severally on a senior unsecured basis by the Partnership's subsidiaries other than Finance Corp., and will be unconditionally guaranteed on the same basis by certain of the Partnership’s future subsidiaries. The 2028 Notes rank equal in right of payment with all existing and future senior indebtedness of the Issuers, and senior in right payment to any future subordinated indebtedness of the Issuers. The 2028 Notes will mature on June 1, 2028, and interest on the 2028 Notes is payable semi-annually in arrears on each June 1 and December 1, commencing December 1, 2021.

At any time prior to June 1, 2024, the Issuers may redeem up to 35% of the aggregate principal amount of the 2028 Notes with the net cash proceeds of one or more equity offerings by the Partnership at a redemption price of 107.125% of the redeemed principal amount, plus accrued and unpaid interest, if any, subject to certain conditions and limitations. Prior to June 1, 2024, the Issuers may also redeem all or part of the 2028 Notes at a redemption price of the principal amount plus accrued and unpaid interest, if any, plus a "make whole" premium, subject to certain conditions and limitations. In addition, beginning on June 1, 2024, the Issuers may, subject to certain conditions and limitations, redeem all or part of the 2028 Notes, at a redemption price of 103.563% of the redeemed principal for the twelve-month period beginning on June 1, 2024, 101.781% for the twelve-month period beginning on June 1, 2025, and 100.00% beginning on June 1, 2026 and thereafter, plus accrued and unpaid interest, if any.

In the event of a change of control, accompanied or followed by a ratings downgrade within a certain period of time, subject to certain conditions and limitations, the Issuers will be obligated to make an offer for the purchase of the 2028 Notes from holders at a price equal to 101% of the principal amount thereof, plus accrued and unpaid interest.

On September 28, 2018, the Partnership entered into a third amended and restated senior secured revolving credit agreement (hereafter, the "DKL Credit Facility") with Fifth Third Bank ("Fifth Third"), as administrative agent, and a syndicate of lenders with total lender commitments of $850.0 million. The DKL Credit Facility contains a dual currency borrowing tranche that permits draw downs in U.S. or Canadian dollars. The DKL Credit Facility also contains an accordion feature whereby the Partnership can increase the size of the credit facility to an aggregate of $1.0 billion, subject to receiving increased or new commitments from lenders and the satisfaction of certain other conditions precedent. The obligations under the DKL Credit Facility remain secured by first priority liens on substantially all of the Partnership's and its subsidiaries' tangible and intangible assets.

The DKL Credit Facility has a maturity date of September 28, 2023. Borrowings denominated in U.S. dollars bear interest at either a U.S. dollar prime rate, plus an applicable margin, or Secured Overnight Financing Rate ("SOFR"), plus an applicable margin, at the election of the borrowers. Borrowings denominated in Canadian dollars bear interest at either a Canadian dollar prime rate, plus an applicable margin, or the Canadian Dealer Offered Rate, plus an applicable margin, at the election of the borrowers.

The applicable margin in each case and the fee payable for any unused revolving commitments vary based upon the Partnership's most recent total leverage ratio calculation delivered to the lenders, as called for and defined under the terms of the DKL Credit Facility. At June 30, 2022, the weighted average interest rate for our borrowings under the facility was approximately 3.35%. Additionally, the DKL Credit Facility requires us to pay a leverage ratio dependent quarterly fee on the average unused revolving commitment. As of June 30, 2022, this fee was 0.30% per year.

In August 2020, the Partnership entered into a First Amendment to the DKL Credit Facility which, among other things, permitted the transfer of cash and equity consideration for the elimination of incentive distribution rights held by Delek Logistics GP, LLC, our general partner. It also modified the total leverage ratio and the senior leverage ratio (each as defined in the DKL Credit Facility) calculations to reduce the total funded debt (as defined in the DKL Credit Facility) component thereof by the total amount of unrestricted consolidated cash and cash equivalents on the balance sheet of the Partnership and its subsidiaries up to $20.0 million.

In May 2022, the Partnership entered into Second and Third Amendments to the DKL Credit Facility which, among other things, provided for the transition from a LIBOR benchmark to a term Secured Overnight Financing Rate benchmark (“Term SOFR”) with credit spread adjustments for 1-month and 3-month Term SOFR loans, and provided consent and flexibility related to the previously announced 3 Bear Acquisition with respect to certain covenants in the DKL Credit Facility. We believe we were in compliance with all covenant requirements as of June 30, 2022.

Further, on May 26, 2022, the Partnership entered into a Fourth Amendment (the “Fourth Amendment”) to the DKL Credit Facility. Among other things, the Fourth Amendment: (i) increased the U.S. Revolving Credit Commitments (as defined in the DKL Credit Facility) by an amount equal to $150.0 million, for an aggregate amount of $1,000.0 million, (ii) increased the U.S. L/C Sublimit (as defined in the DKL

As of June 30, 2022, the Partnership had $880.9 million of outstanding borrowings under the DKL Credit Facility, with no letters of credit in place. Unused credit commitments under the DKL Credit Facility as of June 30, 2022 were $119.1 million.

On May 23, 2017, the Partnership and Delek Logistics Finance Corp., a Delaware corporation and a wholly-owned subsidiary of the Partnership (“Finance Corp.” and together with the Partnership, the “Issuers”), issued $250.0 million in aggregate principal amount of 6.75% senior notes due 2025 (the “2025 Notes”) at a discount. The 2025 Notes are general unsecured senior obligations of the Issuers. The 2025 Notes are unconditionally guaranteed jointly and severally on a senior unsecured basis by the Partnership's existing subsidiaries (other than Finance Corp., the "Guarantors") and will be unconditionally guaranteed on the same basis by certain of the Partnership’s future subsidiaries. The 2025 Notes rank equal in right of payment with all existing and future senior indebtedness of the Issuers, and senior in right of payment to any future subordinated indebtedness of the Issuers. Interest on the 2025 Notes is payable semi-annually in arrears on each May 15 and November 15.

The Issuers may, subject to certain conditions and limitations, redeem all or part of the 2025 Notes at a redemption price of 101.688% of the redeemed principal during the twelve-month period beginning on May 15, 2022 and 100.00% beginning on May 15, 2023 and thereafter, plus accrued and unpaid interest, if any. In the event of a change of control, accompanied or followed by a ratings downgrade within a certain period of time, subject to certain conditions and limitations, the Issuers will be obligated to make an offer for the purchase of the 2025 Notes from holders at a price equal to 101% of the principal amount thereof, plus accrued and unpaid interest.

On April 25, 2018, we made an offer to exchange the 2025 Notes and the related guarantees that were validly tendered and not validly withdrawn for an equal principal amount of exchange notes that are freely tradeable, as required under the terms of the original indenture. The terms of the exchange notes that were issued in May 2018 as a result of the exchange (also referred to as the "2025 Notes") are substantially identical to the terms of the original 2025 Notes.
