Explanation of Responses:

* If the form is filed by more than one reporting person, see Instruction 4(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) The reporting persons are: (i) Steelhead Partners, LLC ("Steelhead"), a registered investment advisor within the meaning of Rule 16a-1(a)(1)(v) under the Securities Exchange Act of 1934; and (ii) each of James Michael Johnston and Brian Katz Klein, Steelhead's member-managers.
(2) 4,018,140 shares of common stock reported in Table I on this Form 4 are beneficially held by Steelhead Navigator Master, L.P. ("Steelhead Navigator"). The balance of the shares reported on this Form 4 is beneficially held by certain client accounts, none of which, other than Steelhead Navigator, is itself the beneficial owner of more than 10% of the issuer's common stock (collectively with Steelhead Navigator, the "Funds").
(3) Steelhead serves as the general partner and/or investment manager of the Funds. As a greater than 10% beneficial owner, Steelhead Navigator is separately reporting its holdings in the issuer's securities on a Form 4 filed concurrently herewith. Each of Steelhead, Mr. Johnston, Mr. Klein and the Funds expressly disclaims beneficial ownership in these securities, except to the extent of their respective pecuniary interests therein.
(4) Steelhead and the other reporting persons may be deemed to beneficially own the securities owned by the Funds insofar as they may be deemed to have the power to direct the voting or disposition of such securities. The reporting persons have elected therefore to file this Form 4 voluntarily to report the Funds' holdings on an aggregate basis, notwithstanding the reporting exemption applicable to registered investment advisors under Rule 16a-1(a)(1)(v) and to control persons under Rule 16a-1(a)(1)(vii). The filing of this Form 4 should not, however, be deemed an admission by any of the reporting persons that such person falls outside the scope of the foregoing exemptions, or that the reporting persons and/or the Funds form a group within the meaning of Rule 16a-1(a)(1).

Note: File three copies of this Form, one of which must be manually signed. If space is insufficient, see Instruction 6 for procedure.

Potential persons who are to respond to the collection of information contained in this form are not required to respond unless the form displays a currently valid OMB number.
