The qualitative portion of the cash bonus to be awarded under the Plan will be determined based on non-financial measures relating to Mr. Wagner’s contributions to the achievement of certain compliance and organizational development objectives. Mr. Wagner’s minimum cash bonus under the Plan for 2012 will be equal to 80% of his pro-rated target level.

The Wagner Letter Agreement further provides that Mr. Wagner will receive an annual equity award with a value of $1,000,000 pursuant to the Company’s 2010 Incentive Compensation Plan. Upon and subject to approval of the Compensation Committee of the Board, the first such equity award is to be made in 2012 in the form of restricted stock units valued at $1,000,000 as of the date of grant.  The restricted stock units will be subject to time-based vesting and such other customary terms and conditions as may be determined by the Compensation Committee.  Mr. Wagner will be eligible to participate in all customary employee benefit plans or programs of the Company generally available to the Company’s employees and/or executive officers.

Additionally, the Wagner Letter Agreement provides that Mr. Wagner’s employment with the Company is at will and may be terminated by either party at any time with or without notice and for any or no reason or cause. Mr. Wagner will be entitled to a lump sum severance payment equal to six months of his then current base salary under certain conditions, including (i) in the event there is a change in the voting control of the Company and his employment is terminated, voluntarily or involuntarily, within six months after such change of control or (ii) in the event Mr. Wagner’s employment is terminated at any time without cause.  Under the terms of the Wagner Letter Agreement, Mr. Wagner may not agree to work for any company that designs, makes or sells non-clinical magnetic resonance instrumentation or mass spectrometry instrumentation for a period of six months following resignation or termination of his employment by the Company.
