Item 1.01. Entry into a Material Definitive Agreement.

On December 21, 2018, BGSL Breckenridge Funding LLC (“SPV”), a wholly-owned subsidiary of Blackstone / GSO Secured Lending Fund (the “Company”), entered into a senior secured revolving credit facility (the “Revolving Credit Facility”) with BNP Paribas (“BNP”). BNP serves as administrative agent, Wells Fargo Bank, National Association serves as collateral agent, and the Company serves as servicer under the Revolving Credit Facility.

Advances under the Revolving Credit Facility bear interest at a per annum rate equal to the three-month London Interbank Offered Rate in effect, plus an applicable margin of 1.50% (or 1.25% prior to the first payment date) to 2.15% per annum depending on the nature of the advances being requested under the facility. SPV will also pay a commitment fee of 0.70% per annum if the unused facility amount is greater than 50% or 0.35% per annum if the unused facility amount is less than or equal to 50% and greater than 25%, commencing six months after the closing date of the Revolving Credit Facility, on the average daily unused amount of the financing commitments until the third anniversary of the Revolving Credit Facility.

The maximum amount of the Revolving Credit Facility is $400 million. Proceeds from borrowings under the Revolving Credit Facility may be used to fund portfolio investments by SPV and to make advances under delayed draw and revolving loans where SPV is a lender. All amounts outstanding under the Revolving Credit Facility must be repaid by the date that is five years after the date of the Revolving Credit Facility.

SPV’s obligations to the lenders under the Revolving Credit Facility are secured by a first priority security interest in all of SPV’s portfolio of investments and cash. The obligations of SPV under the Revolving Credit Facility are non-recourse to the Company, and the Company’s exposure under the Revolving Credit Facility is limited to the value of the Company’s investment in SPV.

In connection with the Revolving Credit Facility, SPV has made certain customary representations and warranties and is required to comply with various covenants, reporting requirements and other customary requirements for similar facilities. The Revolving Credit Facility contains customary events of default for similar financing transactions, including if a change of control of SPV occurs or if the Company is no longer the servicer of SPV. Upon the occurrence and during the continuation of an event of default, BNP may declare the outstanding advances and all other obligations under the Revolving Credit Facility immediately due and payable. The occurrence of an event of default (as described above) suspends the ability of the SPV to acquire or sell additional assets.

The foregoing description is only a summary of the material provisions of the Revolving Credit Facility and is qualified in its entirety by reference to a copy of the Revolving Credit Facility, which is filed as Exhibit 10.1 to this Current Report on Form 8-K and incorporated by reference herein.

Item 2.03. Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant
