What would happen if I buy WSC and then Buffet would buy the remaining 20% of the company?

As you know Warren B. owns 80% of WSC and is planning to buy the remaining 20% of the company for $385 per share and remove it from the public markets. What if I buy some shares of WSC today and then Warren makes his move? What happens to my shares? do I get my money back? do I get some shares of BRK-B? what happens?
