On July 11, 2015, Jarden Corporation (the “Company”) entered into an Agreement and Plan of Merger (the “Merger Agreement”) by and among TWG Merger Sub, Inc., a wholly-owned subsidiary of the Company (“Merger Sub”), Waddington Group, Inc.

Pursuant to the terms of the Merger Agreement, the Company will acquire Waddington for approximately $1.35 billion in cash, subject to working capital and other adjustments.

The Merger Agreement includes customary representations, warranties and covenants by the parties. Subject to the satisfaction of certain customary closing conditions and regulatory approvals, the closing of the transactions contemplated by the Merger Agreement (the “Closing”) is expected to occur in the third quarter of 2015. The Merger Agreement contains certain termination rights for both the Company and Waddington.

The Merger Agreement has been included to provide stockholders with information regarding its terms.

The Merger Agreement contains representations and warranties that the parties to the Merger Agreement made to and solely for the benefit of each other. Moreover, information concerning the subject matter of such representations and warranties may change after the date of the Merger Agreement, which subsequent information may or may not be reflected in the Company’s public disclosures.
