If the deal doesn't renew in 2015, then there is a five year wind down period where Veeva can sell a limited number new licenses but still use the platform. Presumably if this happens, they'll have to rebuild it. It's addressed in the S1.
I saw the wind-down language but it lacks specifics. I figure there's a slim chance of non-renewal anyway but sometimes these things get awkward.
Interesting thing about Veeva is that unlike every other saas company on earth, they actually have a healthy operating margin despite being in hyper-growth mode. This will close on the first day of trading with a $4.5 billion enterprise value.
