Item 1.01. Entry into a Material Definitive Agreement.

On November 16, 2018, BGSL Jackson Hole 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 JPMorgan Chase Bank, National Association (“JPM”). JPM serves as administrative agent, Citibank, N.A., serves as collateral agent and securities intermediary, Virtus Group, LP, serves as collateral administrator, and the Company serves as portfolio manager 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 the applicable margin of 2.50% per annum. SPV will also pay a commitment fee of 0.60% per annum (or 0.375% per annum until the date that is nine months from the date the Revolving Credit Facility was entered into), commencing 60 days 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 initial principal amount of the Revolving Credit Facility is $300 million. The Revolving Credit Facility has an accordion feature, subject to the satisfaction of various conditions, which could bring total commitments under the Revolving Credit Facility to up to $600 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 term loans where SPV is a lender. All amounts outstanding under the Revolving Credit Facility must be repaid by the date that is four years and six months 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 portfolio manager of SPV. Upon the occurrence and during the continuation of an event of default, JPM 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) or a market value event (as defined in the Revolving Credit Facility) triggers a requirement that SPV obtain the consent of JPM prior to entering into any sale or disposition with respect to portfolio assets, and the occurrence of a market value event triggers the right of JPM to direct SPV to enter into sales or dispositions with respect to any portfolio assets, in each case in JPM’s sole discretion.

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.
