The Wildcat Oil Company is trying to decide whether to lease or buy a new computerassisted drilling system for its oil exploration business. Management has decided that it must use the system to stay competitive; it will provide $$4\mathrm{.}1$ million in annual pretax cost savings. The system costs $$9\mathrm{.}1$ million and will be depreciated straight$-$line to zero over $5$ years. Wildcat's tax rate is $22$ percent, and the firm can borrow at $8$ percent. Lambert Leasing Company has offered to lease the drilling equipment to Wildcat for payments of $$2\mathrm{.}12$ million per year. Lambert's policy is to require its lessees to make payments at the start of the year.
