Item 4.

Ownership

Provide the following information regarding the aggregate number and percentage of the class of securities of the issuer identified in Item 1.

(a)

Amount beneficially owned:   

See the responses to Item 9 on the attached cover pages.

The number of shares of Class A Common Stock reported in this Schedule 13G includes 8,065,492 shares of Class A Common Stock (the “Option Shares”) that GV has the right to acquire upon exercise of an option right pursuant to the Class A Common Stock Purchase Agreement, dated as of October 18, 2013, between GV and the Issuer (the “Purchase Agreement”) (a copy of which was previously filed as Exhibit 99.4 to the Issuer’s Current Report on Form 8-K, filed with the SEC on October 21, 2013). For purposes of this Schedule 13G, the number of the Option Shares has been calculated assuming that the option right had been exercised on the date hereof at an exercise price per share of $0.93, 75% of the average of the daily volume weighted average price of the Class A Common Stock for the twenty (20) trading days immediately prior to the date hereof. However, the number of shares issuable under the option right and the exercise price for such shares are not fixed. The number of shares that may be purchased under the option right will equal $7.5 million divided by the exercise price per share specified in the Purchase Agreement. As more fully described in the Purchase Agreement, the exercise price will equal 75% of the average of the daily volume weighted average price of the Class A Common Stock for the twenty (20) trading days immediately prior to the date GV provides notice of exercise of the option right, provided that in no event will the exercise price exceed the conversion price applicable to the Senior Secured Mandatorily Convertible Notes due 2020 issued by the Issuer on October 21, 2013, which conversion price is $2.897 (subject to certain anti-dilution adjustments, including to account for dilutive issuances of additional shares of Class A Common Stock). Based on the current maximum exercise price per share of $2.897, GV has the right to acquire 2,588,885 Option Shares under the Purchase Agreement, which is the number of Option Shares reported, in accordance with the applicable rules, by the Reporting Persons in their Initial Statement of Beneficial Ownership of Securities on Form 3 that was filed with the Securities and Exchange Commission on October 31, 2013.

(b)

Percent of class:
