Each New Subsidiary hereby agree as follows:

1. Each New Subsidiary hereby acknowledges, agrees and confirms that, by its execution of this Supplement, such New Subsidiary will be deemed to be a Guarantor for all purposes of the Bridge Note and shall have all of the rights, benefits, duties and obligations of a Guarantor thereunder as if it had executed the Bridge Note as a Guarantor. Each New Subsidiary hereby ratifies, as of the date hereof, and agrees to be bound by, all of the terms, provisions and conditions contained in the Bridge Note, including, without limitation, (a) all of the covenants set forth in Section 11 of the Bridge Note and (b) all of the guaranty obligations set forth in Section 9 of the Bridge Note. Without limiting the generality of the foregoing terms of this paragraph 1, each New Subsidiary, hereby agrees that it is, jointly and severally with the other Guarantors, liable for, and as primary obligor and not merely as surety, and absolutely and unconditionally and irrevocably guarantees to the Payee the full and prompt payment upon the failure of the Obligor to do so, when and as the same shall become due, whether at stated maturity, upon acceleration or otherwise, and at all times thereafter, of the Guarantied Obligations in accordance with Section 9 of the Bridge Note. Each reference to a “Guarantor” in the Bridge Note shall be deemed to include each New Subsidiary.

Each New Subsidiary (a) is a duly organized or formed and validly existing corporation or other registered entity in good standing under the laws of the jurisdiction of its organization and has the corporate or other organizational power and authority to own its property and assets and to transact the business in which it is engaged and (b) has duly qualified and is authorized to do business and is in good standing in all jurisdictions where it does business or owns assets, except where the failure to be so qualified could not reasonably be expected to result in a Material Adverse Effect.

b.Power and Authority; Enforceability. Each New Subsidiary has the corporate or other organizational power and authority to execute, deliver and carry out the terms and provisions of this Supplement and each other Bridge Loan Document to which it is a party and has taken all necessary corporate or other organizational action to authorize the execution, delivery and performance of this Supplement and each other Bridge Loan Document. Each New Subsidiary has duly executed and delivered this Supplement and each other Bridge Loan Document to which it is a party and this Supplement constitutes, and each other Bridge Loan Document to which it is a party, constitutes the legal, valid and binding obligation of each New Subsidiary enforceable against such New Subsidiary in accordance with its terms, subject to the effects of bankruptcy, insolvency, fraudulent conveyance, moratorium, reorganization and other similar laws relating to or affecting creditors’ rights generally and general principles of equity (whether considered in a proceeding in equity or law).

c.No Violation. None of the execution, delivery and performance by each New Subsidiary of this Supplement and each other Bridge Loan Document to which it is a party and compliance with the terms and provisions thereof or the consummation of the other transactions contemplated hereby or thereby on the relevant dates therefor will (i) contravene any applicable provision of any material applicable law of any governmental authority, (ii) violate any provision of the organization documents of any New Subsidiary or (iii) conflict with the Indenture or the ABL Credit Agreement.

4. The security interest created hereby secures the payment and performance of the Bridge Note. Without limiting the generality of the foregoing, this Supplement secures the payment of all obligations owed under the Bridge Note and would be owed by the Obligor to the Payee but for the fact that they are unenforceable or not allowable (in whole or in part) as a claim in an Insolvency Proceeding involving the Obligor due to the existence of such Insolvency Proceeding.

5.
