On July 30, 2015, Jarden Corporation (the “Company”) entered into Amendment No. 1 to its Amended and Restated Credit Agreement (as defined below) (the “Amended and Restated Credit Agreement Amendment”) which amended certain provisions of the Amended and Restated Credit Agreement, dated as of December 19, 2014 (as amended, supplemented, restated or otherwise modified from time to time, the “Amended and Restated Credit Agreement”), among the Company, as the US Borrower, Jarden Lux Holdings S.à r.l. and Jarden Lux Finco S.à r.l., Barclays Bank PLC, as administrative agent and collateral agent (the “Administrative Agent”), and the several lenders (the “Lenders”) and letter of credit issuers from time to time party thereto. Jarden Lux Holdings S.à r.l. and Jarden Lux Finco S.à r.l. are wholly-owned direct or indirect subsidiaries of the Company.

The Amended and Restated Credit Agreement Amendment was entered into in order to implement a facilities increase under the Amended and Restated Credit Agreement in an aggregate principal amount of $900,000,000 comprising (a) a $300,000,000 increase in the Company’s Tranche B-1 Term Loan Facility maturing on September 30, 2020, and (b) a $600,000,000 new Tranche B-2 Term Loan Facility maturing on July 30, 2022.

In connection with the execution of the Amended and Restated Credit Agreement Amendment, the Company and each existing guarantor under the Amended and Restated Credit Agreement executed a Consent, Agreement and Affirmation of Guaranty and Pledge and Security Agreement (the “Consent”) whereby they consented to the terms of the Amended and Restated Credit Agreement Amendment and agreed that the terms of the Amended and Restated Credit Agreement Amendment will not affect in any way their respective obligations and liabilities under any loan document.

The foregoing summary description of the Amended and Restated Credit Agreement Amendment, the Consent and the transactions contemplated thereby are not intended to be complete, and are qualified in their entirety by the complete texts of the Amended and Restated Credit Agreement Amendment and the Consent, copies of which are filed with this Current Report on Form 8-K as Exhibits 10.1 and 10.2, respectively, and are incorporated herein by reference as though they were fully set forth herein.

On July 31, 2015, the Company completed the previously announced acquisition (the “Acquisition”) of Waddington Group, Inc., a Delaware corporation (“Waddington”), pursuant to an Agreement and Plan of Merger, dated as of July 11, 2015 (the “Merger Agreement”) by and among TWG Merger Sub, Inc., a wholly-owned subsidiary of the Company (“Merger Sub”), Waddington, and Olympus Growth Fund V, L.P., solely in its capacity as the representative of the equityholders of Waddington. Pursuant to the terms of the Merger Agreement, the Company acquired 100% of the equity interests of Waddington for approximately $1.35 billion in cash, subject to working capital and other adjustments. The Company financed the Acquisition with the proceeds from its recently completed common stock offering and the facilities increase described in Item 1.01 of this Current Report on Form 8-K.
