Several ways to go with this one, I'll let everyone else decide.
A) Scientology is a dangerous cult.
There I've said it and I have not been arrested. (Yet.)
B) I would sign any contract for that length of time, because a contract that's unenforceable is not valid, therefore no risk.
C) I am already biologically programmed for my "mission": to ensure the survival of human DNA by encouraging sustainable reproduction of it.* I am happy to sign a long contract wherein I encourage the best such conditions, as is possible within my reach.
* I do not personally have to reproduce for my mission to be successful. My mission is to reproduce human DNA, not my own personal DNA, something I have probably failed to do. That said, history shows that there was at least one evil dictator who demanded that he personally deflower all virgins of his nation, once they came of age. Although I'm not an evil dictator, I do believe that humanity would be served well if I provided half the DNA for it. That's ego for ya.
P.S. I know what you're thinking, and no! the lolita tail would actually be a burden, as my preferences don't go that way. At all. But I'm willing to take several hundred thousand for the team.
