Dear David,


 


It is our pleasure to offer you the position of Senior Vice President, Global Commercial Operations with Affymetrix.  We are excited about the experience and potential you bring to our company. You will report directly to Frank Witney, and be based in the Santa Clara, CA office.

You will be eligible to participate in the Affymetrix Annual Bonus Program with an award level targeted at 50 percent of annual base salary.  The Board of Directors determines each year whether to fund the Bonus Program and the extent to which it will be funded.

For employees with a start date on or after October 1st, you will be ineligible to participate in this program for this calendar year.  However, your full participation will begin January 1st of next year.


 


Additionally, we will recommend to the Compensation Committee of the Board of Directors of Affymetrix that you be granted two equity awards.

These shares will vest 25% per year over a four (4) year period beginning on the grant date, provided that you continue to be an employee of Affymetrix on such anniversary dates.







 


The terms of these equity awards will be governed in all respects by the terms of the applicable Affymetrix equity incentive plans and the equity award agreements that will be provided to you after commencement of your employment.
