(1) Pursuant to the Exchange Agreement (defined below), Mr. Pell exchanged 600,000 New Class A Units for 600,000 shares of Class A common stock on April 24, 2012. In connection therewith, on April 24, 2012, Mr. Pell delivered 600,000 shares of Class B common stock for cancellation. The Issuer entered into an exchange agreement (the "Exchange Agreement") with Mr. Pell on September 29, 2009. Pursuant to the Exchange Agreement, as amended, Mr. Pell (and certain of his permitted transferees, including the Pell Family Trust) are permitted to exchange their new class A units (the "New Class A Units") in Artio Global Holdings LLC for shares of the Issuer's Class A common stock on a one-for-one basis (each such exchange, an "Exchange"), subject to customary conversion rate adjustments for stock splits, stock dividends and reclassifications and other similar transactions. (see note 2)
(2) The New Class A Units represent membership interests in Artio Global Holdings LLC, a subsidiary of the Issuer. In connection with each Exchange, Mr. Pell must deliver, for cancellation, a number of shares of Class B common stock equal to the number of New Class A Units being Exchanged.
