Shinn has been in negotiations to sell the team to minority owner and Louisiana native Gary Chouest since last spring, but talks have been stalled for months.
Chouest, who owns 35 percent of the team, runs a business that supplies vessels to the gulf oil industry. Recently, he has become concerned about his ability to run his family business while taking over the Hornets, said the person who confirmed the NBA's planned purchase of the club.
