The following constitutes Amendment No. 5 to the Schedule 13D filed by the undersigned ("Amendment No. 5").  This Amendment No. 5 amends the Schedule 13D as specifically set forth herein.
Item 5.                          Interest in Securities of the Issuer.
Item 5(a) is hereby amended and restated to read as follows:
(a)            The aggregate percentage of Shares reported owned by each person named herein is based upon 85,339,007 Shares outstanding, which is the total number of Shares outstanding as of November 6, 2015, as reported in the Issuer's Quarterly Report on Form 10-Q filed with the Securities and Exchange Commission on November 12, 2015.
As of the close of business on February 3, 2016, Long Alpha LLC owned directly 160,795 Shares, constituting less than 1% of the Shares outstanding, Long Alpha Ltd owned directly 587,779 Shares, constituting less than 1% of the Shares outstanding and Global Master Fund owned directly 7,701,426 Shares, constituting approximately 9.0% of the Shares outstanding. By virtue of their respective relationships with the Funds discussed in further detail in Item 2, each of Tourbillon and Mr. Karp may be deemed to beneficially own the Shares owned directly by the Funds.
Each Reporting Person, as a member of a "group" with the other Reporting Persons for the purposes of Section 13(d)(3) of the Securities Exchange Act of 1934, as amended, may be deemed the beneficial owner of the Shares directly owned by the other Reporting Persons. Each Reporting Person disclaims beneficial ownership of such Shares except to the extent of his or its pecuniary interest therein.
Item 6. Contracts, Arrangements, Understandings or Relationships With Respect to Securities of the Issuer.
The first paragraph of Item 6 is hereby amended and restated to read as follows:
Each of Long Alpha LLC, Long Alpha Ltd and Global Master Fund have entered into notional principal amount derivative agreements (the "Derivative Agreements") in the form of cash settled swaps with respect to 842,710, 4,633,321 and 6,538,748 Shares, respectively (representing economic exposure comparable to approximately 1.0%, 5.4% and 7.7% of the Shares, respectively). Collectively, the Derivative Agreements held by the Reporting Persons represent economic exposure comparable to an interest in approximately 14.1% of the Shares outstanding. The Derivative Agreements provide each of Long Alpha LLC, Long Alpha Ltd and Global Master Fund with economic results that are comparable to the economic results of ownership. The Derivative Agreements do not provide the Reporting Persons with the power to vote or direct the voting or dispose of or direct the disposition of the shares that are referenced in the Derivative Agreements (such shares, the "Subject Shares"). The Reporting Persons disclaim beneficial ownership in the Subject Shares. The counterparties to the Derivative Agreements are unaffiliated third party financial institutions.
