ITEM 4.

OWNERSHIP.

Provide the following information regarding the aggregate number and percentage of the class of securities of the issuer identified in Item 1.

(a)

Amount beneficially owned:

As of the date of this filing, due to the Ownership Limitation (as defined below), each of the Reporting Persons may be deemed the beneficial owner of 2,033,723 shares of Common Stock through securities held by Castlerigg Master Investments. The 2,033,723 shares of Common Stock beneficially owned by the Reporting Persons consist of: (i) 1,565,358 shares of Common Stock, and (ii) 468,365 shares of Common Stock into which the convertible notes and/or the warrants held by Castlerigg Master Investments are convertible or exercisable, as applicable.

Notwithstanding the above, as of the date of this filing, Castlerigg Master Investments holds (x) a senior secured convertible note convertible into an aggregate of 1,720,000 shares of Common Stock, (y) a convertible note convertible into an aggregate of 4,225,796 shares of Common Stock, and (z) warrants held by Castlerigg Master Investments exercisable for an aggregate of 8,912,961 shares of Common Stock (the notes and warrants described above shall collectively be referred to herein as the “Convertible Securities”). Due to the Ownership Limitation, the Reporting Persons disclaim beneficial ownership of the remaining 14,390,392 shares of Common Stock into which the Convertible Securities would otherwise be convertible or exercisable, as applicable.

In accordance with Rule 13d-4 under the Securities Exchange Act of 1934, as amended, the number of shares of Common Stock into which the Convertible Securities are convertible or exercisable, as applicable, are limited pursuant to the terms of the Convertible Securities to that number of shares of Common Stock which would result in Castlerigg Master Investments (and its affiliates) having aggregate beneficial ownership of 9.99% of the total issued and outstanding shares of Common Stock (the “Ownership Limitation”). The Reporting Persons disclaim beneficial ownership of any and all shares of Common Stock issuable upon any conversion or exercise of the Convertible Securities if such conversion or exercise would cause the aggregate beneficial ownership of Castlerigg Master Investments (and its affiliates) to exceed or remain above the Ownership Limitation (as is currently the case).

(b)

Percent of Class:

The Reporting Persons beneficially own 2,033,723 shares of Common Stock representing 9.99% of all the outstanding shares of Common Stock.

The calculation of the Reporting Persons’ beneficial ownership is based on the 18,323,872 shares of Common Stock issued and outstanding as of February 29, 2008 as reported in an Exhibit to the Issuer’s 8-K filed on March 3, 2008 (plus the 1,250,000 shares of Common Stock issued to Castlerigg Master Investments on February 29, 2008 and other shares issued to the Reporting Persons upon conversion of Convertible Securities).

(c)

Number of shares as to which such person has:

(i)

Sole power to vote or to direct the vote

Not applicable.

(ii)

Shared power to vote or to direct the vote of shares of Common Stock:

Castlerigg Master Investments, Castlerigg International, Castlerigg Holdings, SAMC and Mr. Sandell have the shared power to vote or direct the vote of 2,033,723 shares of Common Stock held by Castlerigg Master Investments.

(iii)

ITEM 6.
