In your work for the Company, you are expected not to make unauthorized use or disclosure of or bring onto Company property any confidential or proprietary information or materials, including trade secrets, of any former employer or other third party to whom you have an obligation of confidentiality.

6.Background Checks. The Company reserves the right to conduct background checks, which may include background investigations and reference checks, on all of its potential employees. This Offer, therefore, is contingent upon a satisfactory clearance of such a background check, background investigation and/or reference check, if any.

This Offer is contingent upon: (i) your execution of this Offer and the PIIA; (ii) your consent to a background check with results satisfactory to the Company in its sole discretion; and (iii) your presentation of satisfactory documentary evidence of your identity and authorization to work in the U.S. within three (3) business days of your Start Date.
