It's a really punitive T&C, especially over that term, which AIB would do well to look at.
Life and circumstances can change hugely over 2 years, with an "expanding funnel of doubt"... the risk of being left high and dry must be weighed against a reward of 3.5% in two years before price inflation (net, assuming PRSI liable).
If you're committed to deposits you could even go for a 3 year State Savings Bond paying 4% net in 3 years, with the option to withdraw on demand at any point (albeit foregoing interest).
I find it hard to sign up for the 2 year fixed term except for balances which I know I'll want to be holding as an absolute minimum in 2 years, come what may.
