Following a lawsuit brought against the warden of the state penitentiary, a judge ordered the state to improve conditions at the $150-$year$-$old facility. The warden works with a state legislator to introduce a bill authorizing funding to build a new penitentiary. If passed and signed by the governor, the state will need to proceed toward buying land for the new facility. This is an example of a B$2$B $\_\_\_\_\_\_\_$ purchase.
