(“PPS”, together with Avicola, the “Borrowers”), certain subsidiaries of the Borrowers (the “Subsidiary Guarantors”), the banks and other financial institutions parties thereto constituting all of the lenders, and ING Capital LLC, as administrative agent and lead arranger entered into a Third Amendment to Amended and Restated Credit Agreement (the “ING Amendment”) to that certain Amended and Restated MXN$557,415,000 Credit Agreement dated as of October 19, 2011 (the “ING Credit Agreement”) by and among the Borrowers, the Subsidiary Guarantors, the banks and other financial institutions party thereto and ING Capital LLC, as administrative agent and lead arranger.

The ING Amendment, among other things, amends the ING Credit Agreement to require that (i) each of the Borrowers and the Subsidiary Guarantors deliver, on an annual basis, audited, non-consolidated financial statements instead of delivering annual audited, consolidated financial statements of the Borrowers and Subsidiary Guarantors and (ii) Avicola deliver, on an annual basis, its unaudited consolidated financial statements. The ING Amendment also amends the ING Credit Agreement to make conforming changes to certain definitions relating to the financial covenant calculations.

The foregoing description of the ING Amendment and the transactions contemplated by the ING Amendment does not purport to be complete and is qualified in its entirety by reference to the text of the ING Amendment, which is attached to this Current Report on Form 8-K as Exhibit 10.1 and incorporated herein by reference.
