-6-

The securities to which this Schedule relates (the “Securities”) are owned by Navigator and by certain client accounts, for which Steelhead serves as general partner and/or investment manager. Steelhead, as general partner and/or investment manager of Navigator and those certain client accounts and as the sole member of Navigator’s general partner, and J. Michael Johnston and Brian K. Klein, as the member-managers and owners of Steelhead, may therefore be deemed to beneficially own Securities owned by Navigator and those certain client accounts for the purposes of Rule 13d-3 of the Securities Exchange Act of 1934, as amended (the “Act”) insofar as they may be deemed to have the power to direct the voting or disposition of those Securities.

Neither the filing of this Schedule nor any of its contents shall be deemed to constitute an admission that Steelhead, Mr. Johnston or Mr. Klein is, for any other purpose, the beneficial owner of any of the Securities, and each of Steelhead, Mr. Johnston and Mr. Klein disclaims beneficial ownership as to the Securities, except to the extent of his or its pecuniary interests therein.

Under the definition of “beneficial ownership” in Rule 13d-3 under the Act, it is also possible that the individual general partners, executive officers, and members of the foregoing entities might be deemed the “beneficial owners” of some or all of the Securities insofar as they may be deemed to share the power to direct the voting or disposition of the Securities. Neither the filing of this Schedule nor any of its contents shall be deemed to constitute an admission that any of such individuals is, for any purpose, the beneficial owner of any of the Securities, and such beneficial ownership is expressly disclaimed.

The calculation of percentage of beneficial ownership in item 11 of pages 2, 3, 4 and 5 was derived from transaction documents the reporting persons and other purchasers entered into with the Issuer on August 25, 2008, in which the Issuer stated that the number of shares of its common stock, no par value per share, outstanding was approximately 157,650,169.
