Royal Bank of Scotland, Fortis and Banco Santander ( STD ) still want ABN Amro ( ABN ). On Monday, the consortium sweetened its $98 billion proposed offer for the Dutch bank, saying ABN shareholders can get 93% of the deal's value in cash -- up from 70% before. ABN Amro agreed in April to a $91 billion merger with U.K. bank Barclays ( BCS ). As part of that agreement, ABN agreed to sell LaSalle to Bank of America for $21 billion. RBS said on Monday that instead of acquiring LaSalle, it will acquire the cash from the sale of the bank to BofA. The consortium plans to break up ABN Amro. The group said it intends to continue with its offer to acquire the Dutch bank's global wholesale businesses and international retail businesses. The move comes just days after the Dutch supreme court ruled ABN Amro was free to sell its Chicago-based retail bank LaSalle to Bank of America ( BAC ) without first getting shareholder approval.
