exs for dummies

Hi,

I brought Exco over a year ago, stuck it in the bottom draw, and are now looking at my options following it becoming ex-div. As such I haven't really kept up with news etc, and I was wondering if someone could explain what all this means for an investor like myself. When are we likely to receive the dividend, how much will it be, and when do I need to continue to hold the stock till for to be eligible for the payment?

Apologies for my ignorance.
