| Price Reduction    | The Price is based on the assumption that assets and liabilities shown in the SPV trial balance updated as at September 30, 2012 and attached to the Framework Agreement, remain not varied and that all proceeds of the SPVs accruing after September 30, 2012 (the “Reference Date”) remain within the SPVs, except for ordinary course of business costs. Without prejudice to indemnification claims, any amount disbursed in breach of the above assumption (the “Disbursements”), to be assessed in accordance with the procedure described in the Framework Agreement, shall be offset against the Price, reducing it accordingly (the “Net Price”). |
