On September 20, 2017, the Borrowers and Lender entered into Amendment Number Seven to Credit Agreement, Waiver and Reaffirmation (the “Seventh Amendment”). Under the terms of the Seventh Amendment, among other things, (i) the maturity date for the revolving and term loan credit facilities was amended to be the earlier of (a) the Global Debenture Maturity (as such term is defined in the Credit Agreement) or (b) March 31, 2018, and (ii) in the event of a failure by the Company to comply with certain covenants and milestones set forth in the Seventh Amendment, all amounts under the Credit Agreement may be accelerated and become immediately payable.
