ITEM 4. PURPOSE OF TRANSACTION

Item 4 of the Original Schedule 13D is hereby amended and supplemented by the addition of the following:

On February 28, 2014, the Issuer completed the previously announced Merger in accordance with the Merger Agreement. At the Effective Time of the Merger, Merger Sub merged with and into the Issuer, with the Issuer continuing as the Surviving Corporation. At the Effective Time, each share of the Issuer’s common stock held by Mr. Rumy was converted into the right to receive $16.75 per share in cash, without interest. In addition, each option to purchase common stock of the Issuer was terminated and the Issuer paid an amount equal to $16.75 less the exercise price of such option. As a result of the consummation of the Merger, Mr. Rumy is no longer the beneficial owner of any shares of the Issuer’s common stock.

ITEM 5. INTEREST IN SECURITIES OF THE ISSUER

Paragraphs (a), (b), (c) and (e) of Item 5 of the Original Schedule 13D are hereby amended and restated in their entirety as follows:
