On March 21, 2013, DJO Finance LLC (the “Company”), an indirect wholly owned subsidiary of DJO Global, Inc., DJO Holdings LLC (“Holdings”) and certain other subsidiaries of the Company amended its senior secured credit facilities by entering into the Amendment No. 1 and Refinancing Term Loan Amendment No. 2 (the “Amendment”) relating to its Credit Agreement dated as of November 20, 2007 and amended and restated as of March 20, 2012 among the Company, Holdings, Credit Suisse AG (formerly known as Credit Suisse), as Administrative Agent, Collateral Agent, Swing Line Lender and L/C Issuer, and each lender party thereto (collectively, the “Lenders”). Among other things, the Amendment provides: (1) for the issuance of approximately $421.4 million of additional term loans to refinance certain of the existing term loans; (2) for the extension of the maturity of certain term loans to September 15, 2017; (3) for the combination of the term loan tranches under the Credit Agreement into a single new term loan tranche (the “New Term Loans”); (4) for the reduction of the interest rate margin applicable to all borrowings under the senior secured credit facilities; and (5) for the setting of the senior secured first lien leverage ratio covenant level at 4.25x for the duration of the agreement. The Company used the net proceeds from the New Term Loans to repay approximately $421.4 million aggregate principal amount of existing term loans outstanding under its senior secured credit facilities and to pay related premiums, fees and expenses.

Effective March 21, 2013, the interest rate margins applicable to borrowings under the senior secured revolving credit facilities are, at our option, either (a) the Eurodollar rate, plus 375 basis points or (b) a base rate determined by reference to the highest of (1) the prime rate, (2) the federal funds rate, plus 0.50% and (3) the Eurodollar rate for a one-month interest period, plus 375 basis points. The interest rate margins applicable to the tranche B term loans are, at our option, either (a) the Eurodollar rate plus 375 basis points or (b) a base rate plus 375 basis points. There is a minimum LIBOR rate applicable to the Eurodollar component of interest rates on tranche B term loan borrowings of 1.00%. The applicable margin for borrowings under the senior secured revolving credit facilities may be reduced, subject to our attaining certain leverage ratios.

Subject to certain exceptions, voluntary prepayments of the New Term Loans within one year of the effective date of the Amendment are subject to a 1.00% “soft call” premium, while other voluntarily prepayments of outstanding loans under the senior secured credit facilities may be made at any time without premium or penalty, provided that voluntary prepayments of Eurodollar loans made on a date other than the last day of an interest period applicable thereto shall be subject to customary breakage costs.

The foregoing description of the Amendment is included to provide you with information regarding its terms. It does not purport to be a complete description and is qualified in its entirety by reference to the full text of the Amendment, which is filed as Exhibit 10.1 hereto and is incorporated herein by reference.
