Case response : Take the $!

The clear answer here is that Eberhart should take the deal to sell the company. His goals are to spend more time in Palo Alto and to leave the winery in good hands. Taking the deal achieves both. The Current CEO Koo is supportive of the deal which will ensure the latter. Selling the company will also ensure the former. Furthermore, if he doesn't sell he will either have to invest in the business or raise more money. These are not consistent with his stated goals. Take the money and run!
