The parties hereto desire to amend certain provisions of the Arrangement Agreement, as permitted by Section 8.1 of the Arrangement Agreement, in order to provide for mutual covenants in connection with the defeasance of the Company Debentures, to clarify the mechanics surrounding the payment of the amounts required to effect such defeasance, and to effect a waiver of certain condition precedents in the Arrangement Agreement relating to the approval of the Company Debenture Transaction (as defined in the Arrangement Agreement); and
