Item 3.

Source and Amount of Funds or Other Consideration.

Item 3 is hereby amended and restated to read as follows:

The Shares purchased by Series One were purchased with working capital (which may, at any given time, include margin loans made by brokerage firms in the ordinary course of business) in open market purchases, except as otherwise noted, as set forth in Schedule A, which is incorporated by reference herein. The aggregate purchase price of the 257,304 Shares beneficially owned by Series One is approximately $1,734,081, including brokerage commissions.

The Shares purchased by VSO II were purchased with working capital (which may, at any given time, include margin loans made by brokerage firms in the ordinary course of business) in open market purchases, except as otherwise noted, as set forth in Schedule A, which is incorporated by reference herein.

Item 4.

Purpose of Transaction.

Item 4 is hereby amended to add the following:

On December 27, 2016, Series One delivered a letter (the “Letter”) to the Issuer nominating Michael Bartholomeusz, Anurag Gupta and Daniel P. McCurdy (the “Nominees”) for election to the Board of Directors of the Issuer (the “Board”) at the 2017 annual meeting of stockholders (the “Annual Meeting”). The Letter also included a stockholder proposal requesting that the Board take the necessary steps to declassify the Board so that all directors are elected on an annual basis. Series One submitted the Letter because it has serious concerns with the Company’s sub optimal performance, weak corporate governance and the Board’s lack of alignment of interests with stockholders. Series One believes the appointment of the Nominees as stockholder representatives to the Board, together with a de-staggering of the Board, will ensure greater accountability to stockholders and help to protect and maximize stockholder value. Representatives of Series One have engaged, and intend to continue to engage, in discussions with the Board regarding matters relating to the composition of the Board.
