Explanation of Responses:

* If the form is filed by more than one reporting person, see Instruction 5(b)(v).
** Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1) Solely for purposes of determining whether a person is a beneficial owner of more than ten percent (a "ten percent owner") of any class of equity securities registered pursuant to section 12 of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), Rule 16a-1 under the Exchange Act ("Rule 16a-1") provides that the term "beneficial owner" shall mean any person who is deemed a beneficial owner pursuant to Section 13(d) of the Exchange Act and the rules thereunder. Rule 13d-3 under the Exchange Act ("Rule 13d-3"), in turn, provides that a person will be deemed to beneficially own all securities over which such person (i) has voting or investment control or (ii) may acquire voting or investment control within 60 days of the date of determination. (Continued in Footnote 2)
(2) For reporting purposes, however, Rule 16a-2 under the Exchange Act ("Rule 16a-2") provides that a person is only deemed to be the beneficial owner of securities if that person has or shares the opportunity, directly or indirectly, to profit or share in any profit derived from a transaction in such securities (a "pecuniary interest"). However, none of the Forest Entities have any pecuniary interest in the Subject Securities (as defined below) and therefore, in accordance with Rule 16a-2, they are not deemed to beneficially own any of the Subject Securities.
(3) The 2017 Convertible Notes may be repaid at any time upon 90 days prior notice.
(4) The final maturity date of the 2017 Convertible Notes is February 25, 2017.
