At IMPs, I would barely think about it and bid 5C.
At MPs, this is close but after thinking about it... well I might bid because I've transmitted UI, and then if they bid 4H, partner might tank also and then I have UI... but I think pass is better.
This isn't just because the risk/reward calculation for this bid is different at MP - it's also because partner's calculation for their 4C bid is different at MP - they might have been bidding 4C hoping for -100 rather than -140, and that's not an IMP consideration.
