Based on the foregoing, we are of the opinion that the Notes have been duly authorized and, when duly executed by the Company, authenticated in accordance with the provisions of the Indenture, and delivered to and paid for by the Agents pursuant to the applicable Terms Agreement, the Notes will constitute valid and legally binding obligations of the Company, enforceable against the Company in accordance with their terms subject to applicable bankruptcy, reorganization, insolvency, moratorium, fraudulent conveyance, receivership or other laws affecting creditors’ rights generally from time to time in effect and subject to general equity principles including, without limitation, concepts of materiality, reasonableness, good faith, fair
