The Frost commitment brings to 69 the pledges the group has received. Phillip Frost is frequently listed as a billionaire on America's most wealthy lists by Forbes and other publications. He developed and sold two major pharmaceutical companies, Key Pharmaceuticals and IVAX. He now heads OPKO Health, another drug company, and is major investor in many other enterprises.
