Pursuant to the policies of Redmile, Mr. Lee holds these securities as a nominee on behalf, and for the sole benefit, of Redmile and has assigned all economic, pecuniary and voting rights in respect of the securities to Redmile. Mr. Lee disclaims beneficial ownership of the securities, and the filing of this Form 4 shall not be deemed an admission that Mr. Lee is the beneficial owner of the securities for purposes of Section 16 of the Securities Exchange Act of 1934, as amended, or for any other purpose.
