On August 16, 2017, Wabash National Corporation (the “Company”) entered into the Third Amendment (“ABL Third Amendment”) to the Amended and Restated Credit Agreement, dated as of May 8, 2012, among the Company, certain of its subsidiaries from time to time party thereto, Wells Fargo Capital Finance, LLC, as administrative agent, and the several lenders from time to time party thereto. The ABL Credit Agreement provides for, among other things, (x) a $175 million senior secured revolving credit facility that matures on June 4, 2020, subject to certain springing maturity events and (y) an uncommitted accordion feature allowing for an increase to the availability under the revolving credit facility of up to $50 million, subject to certain conditions.

On August 18, 2017, the Company entered into Amendment No. 4 (“Term Loan Amendment No. 4,” and collectively with the ABL Third Amendment, the “Amendments”) to the Credit Agreement, dated as of May 8, 2012, among the Company, Morgan Stanley Senior Funding, Inc., as administrative agent, and the several lenders from time to time party thereto. The Term Loan Credit Agreement provides for, among other things, (x) a $189.5 million senior secured term loan that matures on March 19, 2022, subject to certain springing maturity events, and (y) an uncommitted accordion feature allowing for additional senior secured term loans of up to $75 million, subject to certain conditions.

The Amendments permit the Company to proceed with the previously announced acquisition of Supreme Industries, Inc. (the “Acquisition”) and (x) issue equity-linked or debt securities (the “Securities Offering”) or (y) incur term loans or undertake other similar credit facilities or debt financings (the “Acquisition Loans”), in an aggregate principal amount not to exceed $325 million, the proceeds of which are to be used, among other things, to consummate the Acquisition. In addition, the Amendments permit the Company to enter into a senior unsecured bridge credit facility of up to $300 million (the “Acquisition Bridge Facility”) to be used to consummate the Acquisition in the event that the proceeds from either the Securities Offering or the Acquisition Loans are not available to the Company at the time of the consummation of the Acquisition. The Amendments also permit the Company to incur certain liens and debt to be acquired by the Company in connection with the Acquisition.
