Not a terrible push but I would have rather folded this. Ok there is a chance that he could have an underpair but you also need to consider that someone has already called your EP raise and so (theoretically) he must be holding a fairly premium hand also.
TT is the sort of hand I'd rather be getting my chips in first with rather than being 2nd in. I also agree with loz, I would have limped and called a small raise. You would have DEFINITELY got away from that flop!
