On October 11, 2016, Surgical Care Affiliates, Inc. (the “Company”) issued a press release announcing its intention to initiate a syndication process with respect to a new term loan facility to refinance its existing term loan facility (the “Refinancing Loan”) and obtain an incremental term loan of $150,000,000 in aggregate principal amount (the “Incremental Term Loan” and, together with the Refinancing Loan, the “New Loans”), pursuant to an incremental amendment to its Credit Agreement, dated as of March 17, 2015, by and among the Company, JPMorgan Chase Bank, N.A., as Administrative Agent, Swing Line Lender and L/C Issuer, and the other lenders from time to time party thereto and other financial institutions party thereto.
