11.6 Assignment; Successors; Subcontractors; Third-Party Beneficiaries.

(a) Neither Party may assign or otherwise transfer any of its rights or obligations under this Agreement without the prior written consent of the other Party, which will not be unreasonably withheld, except that subject to compliance with Section 2.6 regarding process and/or facility change(s), either Party may assign, in whole or in part, without such consent any of its rights or obligations under this Agreement (i) to any Affiliate of such Party, provided that any such assignment to an Affiliate shall not relieve such Party as the primary obligor hereunder, or (ii) in connection with the merger, consolidation or sale of the stock or substantially all of the assets of the such Party's business responsible for the performance of this Agreement.
