@ NOTJUSTYET - Look at No.6 in the "contract."
What is the vow of poverty
Partly on topic was a question I had asked about this matter here, just a few weeks ago:
Yes if you made money from a side job you are supposed to give it to them but they would usually gift it back to you.
I never saw anyone actually turn the money over. I guess it was an unwritten rule that no one cared about your money as long as you took a vacation day.
