Basically, you email them and then you will get more details like cost, etc. There is no commitment until you sign an agreement. If you don't like the terms of the contract then don't sign and nothing is lost.
BTW, so far I haven't seen any agreement so I really can't say what it contains or doesn't contain yet. I did participate in the original Eyetech A1-XE program when it came out so I figure I'll look into this one as well.
