Who does the modification benefit?

I applied for a Bank of America modification last year and I have just now received the paperwork.  They want to increase my payment by about $ 100 per month and add $ 10,000 to the total.  This means that I would owe $ 10,000 more now on the home than when I bought it 6 years ago.  So I would now owe $ 99,000 on a house that I paid $ 89,000 for and have been told is only worth $ 75,000.  I wonder how BofA thinks those of us who want to keep our homes are going to be able to afford their modification?
