On December 17, 2012, Vitamin Shoppe, Inc. (the “Company”) and Vitamin Shoppe Mariner, Inc., a Delaware corporation and wholly-owned subsidiary of the Company (“VS-Mariner”), entered into an Asset Purchase Agreement (the “Agreement”) with Super Supplements, Inc. (“Super Supplements”) and its sole shareholder, John Wurts (“Shareholder”), pursuant to which VS-Mariner agreed to purchase assets, and assume certain liabilities, comprising the Super Supplements’dietary and supplement retail business, including 31 retail store locations, distribution center in Seattle, Washington and e-commerce business (the “Acquisition”). The purchase price for the Acquisition is $50 million, subject to a post-closing working capital adjustment, and will be funded with cash on hand.

The Agreement contains customary representations, warranties and covenants, as well as indemnification provisions by Super Supplements and Shareholder in favor of VS-Mariner, which are secured, in part, by a third party escrow. The completion of the Acquisition is subject to certain customary closing conditions and is expected to close on December 31, 2012. Prior to signing, Super Supplements obtained the consents of all landlords whose consent is required for Super Supplements to transfer leases to VS-Mariner at closing.

The Agreement contains representations, warranties and disclosures that were made by the parties to each other as of specific dates and to evidence their agreement on various matters. These representations, warranties and disclosures were made solely for purposes of the Agreement and may be subject to exceptions and qualifications contained in separate disclosure schedules; may represent the parties’ risk allocation in the Acquisition; or may be qualified by materiality standards that differ from what may be viewed as material for securities law purposes.

The foregoing description of the Agreement is a summary and is qualified in its entirety by reference to the Agreement, a copy of which is filed as Exhibit 10.01 to this Current Report on Form 8-K and is incorporated herein by reference.
