The Asset Purchase Agreement is intended to constitute a “stalking horse” bid that is subject to higher and better bids by third parties in accordance with bidding procedures to be approved by the Bankruptcy Court. The Asset Purchase Agreement requires the Debtors to obtain Bankruptcy Court approval of the bidding procedures by April 1, 2019 and the Sale Order on or before 45 days after the Bankruptcy Court’s entry of the bidding procedures. In connection with the Chapter 11 Cases, the Company and certain of its U.S. subsidiaries (collectively, the “DIP Borrowers”) will enter into a Senior Secured, Priming and Superprioity Debtor-in-Possession Credit Agreement (the “DIP Credit Agreement”) with the lenders party thereto from time to time (the “DIP Lenders”) and Wells Fargo Bank, National Association, as administrative agent for the DIP Lenders (the “DIP Administrative Agent”),. The DIP Credit Agreement is subject to approval of the Bankruptcy Court and will become effective upon, in addition to other customary closing conditions, the entry of the Interim Order (as defined in the DIP Credit Agreement). The DIP Credit Agreement provides for a $60,000 debtor-in-possession revolving credit facility (the “DIP Facility”). Pursuant to the terms of the DIP Credit Agreement, interest will accrue on the principal balance of the DIP Loans (as defined in the DIP Credit Agreement) at a rate per annum equal to (a) LIBOR for such interest period plus 7.00% in respect of Eurodollar Loans (as defined in the DIP Credit Agreement) and (b) the alternate base rate plus 6.00% in respect of ABR Borrowings (as defined in the DIP Credit Agreement).
