On October 13, 2015, Jarden Corporation (the “Company”) entered into an Agreement and Plan of Merger (the “Merger Agreement”), by and among VHC Merger Sub, Inc., a wholly-owned subsidiary of the Company (“Merger Sub”), Visant Holding Corp.

The Company will acquire Visant for an enterprise value of approximately $1.5 billion, subject to certain purchase price adjustments.

The Merger Agreement includes customary representations, warranties and covenants by the parties. Subject to the satisfaction of certain customary closing conditions, the closing of the transactions contemplated by the Merger Agreement is expected to occur in the fourth quarter of 2015. The Merger Agreement contains certain termination rights for both the Company and the stockholder representatives named therein.

The Merger Agreement has been included to provide stockholders with information regarding its terms. Except for its status as a contractual document that establishes and governs the legal restrictions among the parties thereto with respect to the transactions described above, the Merger Agreement is not otherwise intended to be a source of factual, business or operational information about the parties. 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.
