The above description is a summary of certain materials terms of the New Warrants and is not complete. This summary is subject to, and is qualified by reference to, the form of warrant certificate evidencing the New Warrants attached as Annex A to the Offer Letter/Prospectus.

Participation in the Offer requires both the tender of a holder’s Original Warrants as set forth in the Offer Letter/Prospectus and such holder’s exercise of the New Warrants, which will happen simultaneously effective as of the Expiration Date if the holder’s Original Warrants are properly tendered in the Offer. Holders may elect to participate in the Offer with respect to some or all of the Original Warrants held. Any Original Warrants that are not tendered in the Offer will remain in full force and effect with no change in the terms of the Original Warrants.

The Offer is conditioned upon the existence of an effective Registration Statement on Form S-4 relating to the registration of the New Warrants and the New Warrant Shares. In addition, if the aggregate number of Original Warrants properly tendered in the Offer by all holders participating in the Offer is greater than 2,000,000, then each of the participating holder’s number of Original Warrants tendered will be reduced on as close to a pro rata basis as is possible as further described in the Offer Letter/Prospectus.

Subject to the potential reduction in the acceptance by the Company of a holder’s tender of Original Warrants as described in the preceding paragraph, in the event that a holder properly tenders Original Warrants in the Offer, the Company will issue such holder an equal number of New Warrants, which will be immediately exercised, and the holder will be issued an equal number of New Warrant Shares.
