Except as set forth below, all Items of the Schedule 13D remain unchanged.  All capitalized terms not otherwise defined herein shall have the meanings given to such terms in the Schedule 13D.

Item 4 of the Schedule 13D is hereby amended and supplemented as follows:

Pursuant to the Registration Rights Agreement, the Company filed a registration statement (the “Resale Registration Statement”) with the Securities and Exchange Commission (the “SEC”) covering the resale of the shares of Common Stock issued in the Merger and the shares of Common Stock underlying the assumed Row 44 warrants, and the Resale Registration Statement was declared effective by the SEC on August 22, 2013.

Sales of shares of Common Stock may be made by each Reporting Person, at any time and from time to time, in the open market (including, without limitation, pursuant to the Resale Registration Statement and/or under Rule 144), in privately negotiated transactions or otherwise. Subject to compliance with the restrictions on transfer set forth in the letter of transmittal and the terms of the Registration Rights Agreement, each Reporting Person, on behalf of its Clients, expects to evaluate on an ongoing basis the Issuer’s financial condition and prospects and its interest in, and intentions with respect to, the Issuer and its investment in the securities of the Issuer, which review may be based on various factors, including, without limitation, the Issuer’s business and financial condition, results of operations and prospects, general economic and industry conditions, the price and availability of shares of the Issuer’s capital stock, the conditions of the securities markets in general and those for the Issuer’s securities in particular, as well as other developments and other investment opportunities. Each Reporting Person, on behalf of its Clients, also reserves the right to acquire additional securities of the Company in the open market, in privately negotiated transactions or to change its intention with respect to any or all of the matters referred to in this Item 4.

Except as set forth in the Schedule 13D, no Reporting Person has any plans or proposals that relate to, or would result in, any actions or events specified in clauses (a) through (j) of Item 4 to Schedule 13D.
