Except as otherwise provided herein, neither this Agreement nor any interest hereunder   shall be assignable by any Party without the prior written   consent of the other (which consent shall not be unreasonably withheld, conditioned or delayed); provided,   however, that either Party may   assign this Agreement   to any   wholly   owned subsidiary or to any successor by merger or sale of substantially all of its business unit to which this Agreement relates. This Agreement shall be binding upon the successors and permitted assignees of the Parties. Any purported assignment in violation of this paragraph shall be void and ineffectual and shall not operate to transfer or assign any interest or title to the purported assignee.
