If, on or within eighteen (18) months after a Change in Control, Optionholder's employment with the Issuer terminates either by the Issuer (or its successor) other than for Cause, or by Optionholder due to a resignation for Good Reason, all then-unvested outstanding shares subject to the Option shall vest in full effective as of the termination or resignation date.
