Explanation of Responses:
1. On April 16, 2009, Tyson Foods, Inc. ("Tyson") exercised the Warrants granted on October 21, 2008 to purchase 8,000,000 shares of the issuer's common stock at the purchase price of $0.01 per share. The Warrants are owned directly by Tyson and may be deemed to be beneficially owned (i) by the Tyson Limited Partnership ("TLP") which has 69.76% of the voting rights in Tyson and (ii) by Donald J. Tyson who has approximately 54% combined interest as a general and limited partner in the TLP and therefore the TLP and Donald J. Tyson have an indirect beneficial ownership in the common stock held by Tyson. The TLP and Donald J. Tyson disclaim any beneficial ownership in the common stock held by Tyson.
