SCHEDULE 13D

This Amendment (the “Amendment”) relates to the Statement of Beneficial Ownership on Schedule 13D filed jointly by Magnetar Financial LLC, a Delaware limited liability company (“Magnetar Financial”), Magnetar Capital Partners LP, a Delaware limited partnership (“Magnetar Capital Partners”), Supernova Management LLC, a Delaware limited liability company (“Supernova Management”), and Alec N. Litowitz (“Mr. Litowitz”) (collectively, the “Reporting Persons”) with the SEC on September 19, 2016 (as amended by this Amendment, the “Schedule 13D”).

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

ITEM 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION

Item 3 Of Schedule 13D is hereby amended to add the following information for updating:

The aggregate amount of funds used by the Reporting Persons in purchasing the 121,475 Shares reported herein on behalf of PRA Master Fund have come directly from the assets of PRA Master Fund controlled by such Reporting Persons and their affiliates, which may, at any given time, have included margin loans made by brokerage firms in the ordinary course of business. The aggregate amount of funds used by the Reporting Persons in purchasing the Shares reported herein on behalf of PRA Master Fund was $11,572,982 (excluding commissions and other execution-related costs).

The aggregate amount of funds used by the Reporting Persons in purchasing the 69,767 Shares reported herein on Schedule A on behalf of the Funds (other than PRA Master Fund) and the Managed Accounts that were bought to cover the short position described in the Schedule 13D that was established on behalf of the Funds (other than PRA Master Fund) and the Managed Accounts have come directly from the assets of the Funds (other than PRA Master Fund) and the Managed Accounts controlled by such Reporting Persons and their affiliates, which may, at any given time, have included margin loans made by brokerage firms in the ordinary course of business and proceeds from the short sale of Shares. The aggregate amount of funds used by the Reporting Persons in purchasing such 69,767 Shares reported herein on Schedule A on behalf of the Funds (other than PRA Master Fund) and the Managed Accounts was $6,684,870 (excluding commissions and other execution-related costs).

ITEM 4. PURPOSE OF TRANSACTION

Item 4 of the Schedule 13D is hereby amended to add the following information for updating:

Since the filing of the 13D with the SEC on September 19, 2016, the Reporting Persons acquired the additional 121,475 Shares reported herein on behalf of PRA Master Fund for the purpose of receiving the merger consideration described in the Schedule 13D upon consummation

of the Merger. The Reporting Persons voted all the Shares reported on behalf of PRA Master Fund in favor of the Merger.

The Reporting Persons previously reported a 108,800 Share short position that was established after the public announcement of the Merger Agreement on behalf of the Funds (other than PRA Master Fund) and the Managed Accounts as a hedge against the call options contracts described in the Schedule 13D purchased on behalf of the Funds (other than PRA Master Fund) and the Managed Accounts. Since the filing of the 13D on September 19, 2016, the Reporting Persons had short sales of 141,142 Shares and purchased 69,767 Shares on behalf of the Funds (other than PRA Master Fund) and the Managed Accounts to close out 69,767 Shares of such short position as of the close of business on December 19, 2016. The Reporting Persons intend to close out the remaining short position on behalf of the Funds (other than PRA Master Fund) and the Managed Accounts subject to prevailing market conditions.

Each of the Reporting Persons reserves the right to acquire additional securities of the Company in the open market, in privately negotiated transactions, or otherwise, to dispose of all or a portion of the Shares and/or other securities reported in this Statement, or to change their intention with respect to any or all of the matters referred to in this Item 4.

Other than as described above in this Item 4, the Reporting Persons do not have 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.

ITEM 5. INTEREST IN SECURITIES OF THE ISSUER

Item 5 of the Schedule 13D is hereby amended to add the following information for updating:

The Company reported in its Schedule 13Q filed with the SEC on November 1, 2016, that 19,722,051 Shares were issued and outstanding as of October 27, 2016.

(a) As of the close of business on December 19, 2016, each of the Reporting Persons may have been deemed to have beneficial ownership of 941,266 Shares, which consists of 941,266 Shares held by Magnetar PRA Fund, and all such Shares represent 4.77% of the Shares.

(b) As of the close of business on December 19, 2016, each of the Reporting Persons may have been deemed to share the power to vote and direct the disposition of 941,266 Shares, which consists of 941,266 Shares held by Magnetar PRA Fund, and all such Shares represented beneficial ownership of approximately 4.77% of the Shares.

(c) Except as set forth on Schedule A attached hereto, the Reporting Persons had no transactions since the filing of the Schedule 13D on September 19, 2016 through the close of business on December 19, 2016. All of the transactions set forth on Schedule A attached hereto were effected in the ordinary course of business of Magnetar Financial for the accounts of each of the Fund and each of the Managed Accounts. The transactions in the Shares set forth on Schedule A were effected in open market transactions on the NASDAQ Global Select Market and various other trading markets. The transactions in the call options contracts described below were effected

in open market transactions on the Chicago Board of Options Exchange and various other trading markets.

(e) Each of the Reporting Persons ceased to have beneficial ownership of greater than 5% of the Shares on December 16, 2016, immediately following expiration of the call options contracts described in the Schedule 13D.

ITEM 6. CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT TO THE SECURITIES OF THE ISSUER

Item 6 of the Schedule 13D is hereby amended to add the following information for updating:

As described in the Schedule 13D, the Reporting Persons previously reported that they purchased exchange-traded call options contracts on behalf of the Funds (other than PRA Master Fund) and the Managed Accounts, which entitled the Funds (other than PRA Master Fund) and the Managed Accounts to purchase 2,176,000 Shares in the aggregate from the sellers of such call options contracts for $100 per Share. The call options contracts held on behalf of the Funds (other than PRA Master Fund) and the Managed Accounts expired on December 16, 2016 without being exercised.

From September 29, 2016 to October 11, 2016, the Reporting Persons purchased exchange-traded call options contracts for $3,590 (excluding commissions and other execution-related costs) in the aggregate on behalf of the Funds (other than PRA Master Fund) and the Managed Accounts, which entitled the Funds (other than PRA Master Fund) and the Managed Accounts to purchase 200,000 Shares in the aggregate from the sellers of such call options contracts for $100 per Share. Such call options contracts expired on November 16, 2016 without being exercised.

The funds used by the Reporting Persons in purchasing all such November call options contracts on behalf of the Funds (other than PRA Master Fund) have come directly from the assets of the Funds (other than PRA Master Fund) controlled by such Reporting Persons and their affiliates, which may, at any given time, have included margin loans made by brokerage firms in the ordinary course of business. The funds used by the Reporting Persons in purchasing all such November call options contracts on behalf of the Managed Accounts have come directly from the assets of the Managed Accounts controlled by such Reporting Persons and their affiliates, which may, at any given time, have included margin loans made by brokerage firms in the ordinary course of business. As described above, the aggregate amount of funds used by the Reporting Persons in purchasing the November call options contracts on behalf of the Funds (other than PRA Master Fund) and the Managed Accounts was $3,590 (excluding commissions and other execution-related costs).

The 141,142 Shares described herein that were sold short on behalf of the Funds (other than PRA Master Fund) and the Managed Accounts were obtained by the Funds (other than PRA Master Fund) and the Managed Accounts from prime brokers pursuant to customary securities lending agreements.

Except as otherwise described herein, no contracts, arrangements, understandings or similar relationships exist with respect to the securities of the Company among or between the Reporting Persons or any other person or entity.
