From my reading it looks like Ceglia was supposed to pay the hosting fees. I wonder how much the hosting fees are and what his bill would look like going back 6 years to now.
Actually, it says that the "Seller [Zuckerberg] agrees to maintain and act as the sites webmaster and to pay for all domain and hosting expenses from the funds received."
It still seems to be a weak point in the contract. Expenses grew beyond what the investor was putting in.
