Europe. From January 1, 2011 through August 31, 2011 (and all prior periods), the Company's European sales were derived from independent distributors. From September 1, 2011 through December 31, 2011, the Company's European sales were derived from (i) its direct European sales force serving the markets of Austria, Belgium, the Czech Republic, Denmark, France, Germany, Luxembourg, The Netherlands, Romania, Sweden, Switzerland, and the United Kingdom (excluding Northern Ireland), and (ii) four independent distributors serving the markets in Italy, Greece, Turkey, and Ireland.

directly marketing and selling its products within the above listed European countries. Additionally, upon mutual agreement,
