From the T&C's you quoted it looks like you will need at least 0.01 ETH in the wallet (which is about $5 worth at the time of writing).
This is pretty standard for airdrops. You should probably grab some ETH into a wallet to make sure you can take part in this and future airdrops. Some of them are pretty epic.
The Polymath one was worth several hundred bucks as I recall!
