The purchase price of the non-qualified options will be the closing NASDAQ market price of Quidel’s stock on your date of hire.

In addition to the above, as a Quidel employee, you will be eligible to participate in our benefits programs, which will take effect on your first day of employment. The specific details of these benefit plans will be provided to you upon your employment.

This offer of employment is contingent upon successfully passing a pre-employment drug screen, background and reference check. We will be in contact with you to set up your drug screen appointment, which must be completed as soon as reasonably possible.

Quidel Corporation is an at-will employer. This means that you have the right to terminate your employment with Quidel at any time, for any reason, with or without notice.
