Item 1.01. Entry into a Material Definitive Agreement

Kinetic Concepts, Inc. and KCI USA, Inc. (together, the “Borrowers”) are operating subsidiaries of Acelity L.P. Inc.

On June 16, 2016, the Borrowers and certain of Acelity L.P. Inc.’s other subsidiaries entered into an Amendment No. 9 to the credit agreement (“Credit Agreement Extension Amendment”) governing their senior secured credit facilities, pursuant to which certain lenders agreed to amend and extend the maturity date for a portion of the existing Term E-1 Loans outstanding under such senior secured credit facilities. Such extended term loans (the “Term F Loans”) will mature on November 4, 2020, with an earlier springing maturity tied to (i) the maturity date of the Borrowers’ 12.5% senior unsecured notes due 2019 and (ii) the maturity date of the Borrowers’ 10.5% second lien senior secured notes due 2018, in each case, if more than $250 million of such notes remain outstanding 90 days prior to their respective maturity dates. In addition, certain lenders agreed to provide incremental Term F Loans, the proceeds of which were used in full to repay a portion of the remaining non-extended Term E-1 Loans.

Pursuant the Credit Agreement Extension Amendment, Term F Loans denominated in dollars will bear interest at a rate equal to, at the Borrowers’ election, a Eurocurrency rate plus 4.00% or an adjusted base rate plus 3.00% and (ii) Term F Loans denominated in euros will bear interest at a rate equal to, at the Borrowers’ election, a Eurocurrency rate plus 4.00% or an adjusted base rate plus 3.00%. The Eurocurrency rate is subject to a floor of 1.00%, and the adjusted base rate is subject to a floor of 2.00%. In addition, certain other covenants were amended in connection with the Credit Agreement Extension Amendment, including with respect to the incurrence of incremental facilities and the making of restricted payments. After giving effect to the Credit Agreement Extension Amendment, the Borrowers will have an aggregate principal amount of $1,707.0 million of Term F Loans denominated in dollars and €239.5 million ($272.8 million) of Term F Loans denominated in euros outstanding, with $195.9 million of non-extended Term E-1 Loans denominated in dollars outstanding.

The foregoing summary does not purport to be complete and is qualified in its entirety by reference to the complete terms of Amendment No. 9, a copy of which is filed as Exhibit 10.1 hereto and incorporated herein by reference.
