His last four positions at BMS were Vice President, Finance roles over the following geographic operating units: United States from 2012 to 2013, Europe from 2008 to 2011, Asia Pacific from 2005 to 2007 and Japan from 2003 to 2005. Prior to that, Mr. Binder served in three senior leadership roles for Oncology Therapeutics Network (“OTN”), a U.S.-based independent subsidiary of BMS: Vice President, Strategic Development from 2001 to 2003, Vice President, Customer Operations from 2000 to 2001 and Chief Financial Officer from 1997 to 2000. Before OTN, Mr. Binder completed three finance and accounting roles for BMS Worldwide Medicines Group after joining BMS in 1992.

In accordance with the Plan, the stock option shall have an exercise price equal to the closing price of our common stock on the date of grant. The foregoing stock option will be evidenced by a Stock Option Grant Notice and Option Agreement (collectively, the “Grant Documents”), which, together with the Plan, will set forth the terms and conditions of the stock option.
