MVA beneficially owns 1,506,854* Common Shares, consisting of 4,187 Common Shares and 1,502,677 Common Shares underlying 7.052 shares of Series C-1’’ Preferred Stock that can be converted into Common Shares to the extent that, after such conversion, the Reporting Persons would beneficially own no more than the Ownership Limitation.

(c)

Number of shares as to which such person has:

(i)

Sole power to vote or direct the vote:

MVA has the sole power to vote the 1,506,854 * Common Shares it beneficially owns. Boxer Capital, Boxer Management and Joseph Lewis do not have the sole power to vote or direct the vote of any Common Shares.

(ii)

Shared power to vote or to direct the vote:

Boxer Capital, Boxer Management and Joseph Lewis have shared voting power with respect to the 1,494,018* Common Shares they beneficially own. MVA does not have shared power to vote or direct the vote of any Common Shares.

(iii)

MVA has the sole power to dispose of the 1,506,854 * Common Shares it beneficially owns. Boxer Capital, Boxer Management and Joseph Lewis do not have the sole power to dispose or direct the disposition of any Common Shares.

(iv)

Shared power to dispose or to direct the disposition of:

Boxer Capital has shared voting and dispositive power with regard to the 1,494,018* Common Shares it owns directly. Boxer Management and Joseph Lewis each have shared voting and dispositive power with regard to the Common Shares owned directly by Boxer Capital.

Neither Boxer Capital, Boxer Management nor Mr. Lewis has any voting or dispositive power with regard to the Common Shares held by MVA.

As of February 12, 2013, the Reporting Persons may be deemed to beneficially own 1,392,714 Common Shares, consisting of 1,031,557 Common Shares and 361,157 Common Shares underlying shares of Series C-1’’ Preferred Stock which are convertible to Common Shares). As of January 28, 2013, the Reporting Persons owned approximately 1,312.928 shares of Series C-1’’ Preferred Stock (the “Preferred Stock”), and 1019.727 of Series D-1’’ Preferred Stock, 2,391 Series C-2’’ warrants, and 2,391 Series D-2’’ warrants (collectively, with the Series D-1’’ warrants and C-2’’ warrants, the “Warrants”). The Warrants are exercisable into additional shares of Preferred Stock, and the conversion price of the Preferred Stock to Common Shares is $.004692. The Preferred Stock can only be converted to the extent that, after such conversion, the Reporting Persons would beneficially own no more than 9.999% of the Issuer’s Common Shares. Because Boxer Capital, Boxer Management, Joseph Lewis and MVA may be deemed to be a group pursuant to Rule 13d, their aggregate beneficial ownership of Common Shares underlying the Preferred Stock cannot exceed 9.999% of the Issuer’s Common Shares.
