In the event of a Change in Control, each outstanding purchase right shall be assumed or an equivalent purchase right substituted by the successor corporation or a Parent or Subsidiary of the successor corporation. In the event that the successor corporation refuses to assume or substitute for the purchase right, the Offering Period then in progress shall be shortened by setting a New Purchase Date and shall end on the New Purchase Date. The New Purchase Date shall be before the date of the Company’s proposed merger or Change in Control. The Company shall notify each Participant in writing, at least ten (10) U.S. business days prior to the New Purchase Date, that the Purchase Date for the Participant’s purchase right has been changed to the New Purchase Date and that Shares shall be purchased automatically for the Participant on the New Purchase Date, unless prior to such date the Participant has withdrawn from the Offering Period as provided in Section 10.
