equal to Employees Base Salary plus one-twelfth of the full years target Annual Bonus for the year in which the termination occurred. In addition, immediately upon an Involuntary Termination, all restrictions on shares described in
Section 4(b) shall lapse causing full vesting of all such shares, and all options to purchase Company stock, that are either held by Employee on the date of this Agreement or are otherwise described in Section 4(c), shall become fully exercisable
through the 1-year anniversary of the Involuntary Termination. If employee elects to continue to receive health insurance benefits following termination, the Company shall pay the full cost of such continuation of coverage during the Severance
Period. A Constructive Termination (as defined below) will be treated as an Involuntary Termination.
