expended certain expenses, in providing administrative services to AHI (including accounting, legal and other services) which AWI has not yet quantified but is entitled to seek reimbursement on from AHI and has not yet sought reimbursement on but
reserves the right to do so, which may, accordingly, produce additional intercompany accounts; and



WHEREAS, AWIs Plan of Reorganization is the product of extensive negotiations among the parties in interest in AWIs Chapter 11 proceeding,
reflecting the compromise of various claims and arguments such parties have asserted or could assert in such proceeding; and



WHEREAS, AWIs Plan of Reorganization provides that the existing equity interest in AWI shall be cancelled in its entirety on the Effective Date but

such approval is obtained, the costs of completing the winding up of AHI; and



WHEREAS, in connection with AWIs Reorganization Plan and AHIs dissolution and winding up, AHI plans to cause AWWD to be merged with and into AHI on or about the Effective Date, with the result that AWWDs
separate corporate existence shall cease and AHI shall come to own all of the then assets of AWWD and shall come to be liable for all the then obligations of AWWD; and



WHEREAS, in order for AHI or AWWD to have any recovery on the AHI Intercompany Account Claims AHI and AWWD would be required
to file the AHI Intercompany Account Claims with the Court and AWI and other parties in interest in AWIs Chapter 11 proceeding would have the opportunity to contest those claims and any recovery on such claims that might otherwise be accorded
to AHI or AWWD, as the case may be, under AWIs Plan of Reorganization; and



WHEREAS, AWI has advised AWWD and AHI that it has been advised by representatives of certain of the parties in interest in AWIs Chapter 11 proceeding that they will object to AHIs Claims if they are
presented to the Court and that other parties in interest may object as well; and



WHEREAS, if AWI were to pursue the AWI Intercompany Account Claims and AWWD and AHI were not able to offset against the AWI Intercompany Account Claims the AHI Intercompany Account Claims, AHI may not be able to
distribute to its shareholders all the Warrants; and



WHEREAS,
