The annual quantitative goals to be achieved will be set either by the Bruker CEO or the Bruker Board of Directors Compensation Committee, based upon the annual business plan for the BBIO Group.  Individual goals shall be discussed between the Employee and the CEO and then will be set by the Bruker CEO or the Bruker Board of Directors Compensation Committee, typically early in the first quarter of each calendar year.

Should such a LTEI grant not be made, total annual compensation will be reviewed.

The LTEI grants will typically be awarded in August of each calendar year and be legally governed by individual Bruker Stock Option and/or Restricted Stock Award Agreements.
