The following constitutes Amendment No. 19 to the Schedule 13D filed by the undersigned (“Amendment No. 19”). This Amendment No. 19 amends the Schedule 13D as specifically set forth herein.

Item 4.

Purpose of Transaction.

Item 4 is hereby amended to add the following:

On July 2, 2017, the Issuer entered into an Agreement and Plan of Merger (the “Merger Agreement”) with ADVA NA Holdings, Inc. (“Parent”), and Golden Acquisition Corporation, a wholly-owned subsidiary of Parent (“Merger Sub”). Pursuant to the terms and subject to the conditions set forth in the Merger Agreement, Merger Sub commenced a tender offer (the “Offer”) to acquire all of the issued and outstanding Shares of the Issuer, including all associated rights under that certain rights agreement, as amended, between the Issuer and American Stock Transfer & Trust Company, LLC, as rights agent, dated as of January 26, 2016, on the terms and subject to the conditions set forth in the Merger Agreement at a price per Share of $10.00 in cash, without interest thereon and subject to any required tax withholding (the “Merger Consideration”).

Raging Capital tendered into the Offer 2,136,864 Shares pursuant to and in accordance with the terms of the Offer. Mr. Traub tendered into the Offer 5,182 Shares in accordance with the terms of the Offer. The Offer expired at 12:00 midnight Eastern Time at the end of August 11, 2017. On August 14, 2017, the Issuer announced that Merger Sub successfully completed the Offer and that Merger Sub merged with and into the Issuer (the “Merger”), with the Issuer continuing as the surviving corporation and as a wholly owned subsidiary of Parent. All remaining restricted stock of the Issuer (both vested and unvested) owned by Messrs. Traub and Bellinger were converted into the right to receive the Merger Consideration in accordance with the terms of the Merger Agreement. All stock options of the Issuer owned by Messrs. Traub and Bellinger were cancelled and converted into the right to receive the Merger Consideration (less the applicable exercise price) in accordance with the terms of the Merger Agreement; provided, however, that if the applicable exercise price per Share under any such options was equal to or greater than the Merger Consideration, such options were cancelled without any payment or other consideration being made or owed in respect thereof. Accordingly, the Reporting Persons no longer beneficially own any securities of the Issuer.

Item 5.

Interest in Securities of the Issuer.

Item 5 is hereby amended and restated to read as follows:

The Reporting Persons no longer beneficially own any securities of the Issuer. There were no transactions in the securities of the Issuer by the Reporting Persons during the past 60 days except as set forth in Item 4.

The Reporting Persons have ceased to be beneficial owners of more than 5% of the Shares.
