(2) The lessor is willing to perform the proposed alterations at a fair and reasonable price.

(3) It is in the Government’s interest to acquire the alterations from the lessor.

(b) If proposed alterations are outside the scope of the existing lease, decide whether to acquire the alterations through either:
