the date of hire, with an option term of five years.

As a mutually agreed condition of employment, you agree that you will waive, to
the maximum extent permitted by law, any and all non-salary benefits you would
normally enjoy as a 3D Systems employee, including without limitation group
insurance, (including group health, dental, vision, life insurance, and long
term disability insurance), a 401(k) plan, employee stock purchase plan, and
flexible spending accounts. You will, however, be entitled to paid sick leave,

month term of this agreement, either party may provide 90 days advance written
notice to the other party terminating this agreement. In addition, your
employment may be terminated at any time by 3D Systems for cause, which shall be
defined as conduct





involving moral turpitude or gross or habitual neglect of your duties. Any other
agreement regarding your employment or any other matter between you and 3D
Systems must be in writing signed by the Chairman of the Board, and approved by
the Compensation Committee of the Board of Directors.
