Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer.

“Controlling Interest in the Issuer” of Item 6 of this Schedule 13D is hereby amended and restated in its entirety as follows:

Controlling Interest in the Issuer

As of the filing of this Amendment No. 4, entities affiliated with the Reporting Persons owned 88.1% of the Issuer’s Class B common stock, which, together with the Class A common stock held by them, represent 82.3% of the combined voting power of the Issuer’s outstanding Class A common stock and Class B common stock, assuming that 53,755,940 shares of Class A common stock and 52,508,834 shares of Class B common stock are outstanding as reported in the Issuer’s Quarterly Report. Under the Issuer’s amended and restated certificate of incorporation that became effective as part of the Issuer’s initial public offering, holders of shares of Class B common stock may generally transfer those shares to affiliated entities, without having the shares automatically convert into shares of Class A common stock. Therefore, the Reporting Persons will, for the foreseeable future, be able to control the outcome of the voting on virtually all matters requiring stockholder approval, including the election of directors and significant corporate transactions such as an acquisition of the Issuer, even if the Reporting Persons come to own, in the aggregate, as little as 10% of the economic interest of the outstanding shares of the Issuer’s Class A common stock and Class B common stock. Moreover, the Reporting Persons may take actions in their own interests that the Issuer’s other stockholders do not view as beneficial.

“Warrants in Connection with the Loan and Security Agreement” of Item 6 of this Schedule 13D is hereby amended to add the following:

On June 17, 2013, the Issuer issued to KFT (i) a Subsequent Drawdown Warrant for 406,923 shares of Class A common stock of the Issuer, (ii) an ATM Warrant for 91,303 shares of Class A common stock of the Issuer and (iii) a Subsequent PIK Warrant for 73,028 shares of of Class A common stock of the Issuer (collectively, the “June 2013 Warrants”), each of which are exercisable for an exercise price of $4.42 per share.

On July 26, 2013, the Issuer issued to KFT (i) a Subsequent Drawdown Warrant for 355,751 shares of Class A common stock of the Issuer, (ii) an ATM Warrant for 79,813 shares of Class A common stock of the Issuer and (iii) a Subsequent PIK Warrant for 62,382 shares of of Class A common stock of the Issuer (collectively, the “July 2013 Warrants”), each of which are exercisable for an exercise price of $5.06 per share.

The foregoing descriptions of the June 2013 Warrants and the July 2013 Warrants do not purport to be complete and are qualified in their entirety by reference to the warrants filed as Exhibits 99.12 through 99.17, respectively, to this Schedule 13D and incorporated herein by reference.

SCHEDULE 13D

CUSIP No. 497219109 Page12 of 15 Pages

Other than as described in this Schedule 13D, to the best of the Reporting Persons’ knowledge, there are no other contracts, arrangements, understandings or relationships (legal or otherwise) among the persons named in Item 2 and between such persons and any person with respect to any securities of the Issuer.

ATTACHMENT A

Mr. Khosla is the managing member of VK Services, which is the manager of KVA II and KVA III. KVA II and KVA III are the general partners of KV II and KV III, respectively. Each of KVA II, KVA III, VK Services and Khosla may be deemed to possess voting and investment control over the shares held by KV II and KV III, and each of KVA II, KVA III, VK Services and Khosla may be deemed to have indirect beneficial ownership of such shares.

Certain securities were originally purchased by KV II and then distributed to KVA II, which in turn distributed such securities to members and affiliates of members of KVA II (the “Distributed Securities”). KVA II continues to possess voting and investment control over the Distributed Securities. Each of KVA II, VK Services and Khosla may be deemed to possess voting and investment control over the Distributed Securities, and each of KVA II, VK Services and Khosla may be deemed to have indirect beneficial ownership of such shares.

Certain securities were purchased in connection with the Issuer’s IPO by KFT. Warrants to purchase Class A common stock have been issued to KFT in connection with a loan and security agreement between the issuer and KFT. Khosla, as a trustee and beneficiary, may be deemed to have indirect beneficial ownership of such shares.

Certain securities were issued by the Issuer to Samir Kaul, who is a director of the Issuer and a member of KVA II and KVA III as compensation for his role as a director of the Issuer. Such shares will vest upon the completion of Mr. Kaul’s term as a director at the Issuer’s next annual meeting. Mr. Kaul holds such securities for the benefit of KV III and KVA III, and, accordingly, KV III, KVA III, VK Services and Khosla may be deemed to have indirect beneficial ownership of such shares.

Each Reporting Person disclaims beneficial ownership of the shares described above except to the extent of his or its pecuniary interest therein.
