Neither Party may assign its rights or delegate its obligations under this Agreement, whether by operation of law or otherwise, in whole or in part without the prior written consent of the other Party, which consent shall not be unreasonably withheld, conditioned or delayed, except that AstraZeneca shall have the right, without such consent, (i) to perform any or all of its obligations and exercise any or all of its rights under this Agreement through any of its Affiliates or its or their (sub)licensees, and (ii) assign any or all of its rights and delegate any or all of its obligations hereunder to any of its Affiliates or its or their (sub)licensees or to any successor in interest (whether by merger, acquisition, asset purchase or otherwise) to all or substantially all of the business to which this Agreement relates; provided that AstraZeneca shall provide written notice to Licensee within [***] ([***]) [***] after such assignment or delegation. Licensee shall have the right, without such consent, (i) to perform any or all of its obligations and exercise any or all of its rights under this Agreement through any of its Affiliates, and (ii) assign any or all of its rights and delegate any or all of its obligations hereunder to any of its Affiliates; provided that Licensee shall provide written notice to AstraZeneca within [***] ([***]) [***] after such assignment or delegation. Any permitted successor of a Party or any permitted assignee of all of a Party’s rights under this Agreement that has also assumed all of such Party’s obligations hereunder in writing shall, upon any such succession or assignment and assumption, be deemed to be a party to this Agreement as though named herein in substitution for the assigning Party, whereupon the assigning Party shall cease to be a party to this Agreement and shall cease to have any rights or obligations under this Agreement. All validly assigned rights of a Party shall inure to the benefit of and be enforceable by, and all validly delegated obligations of such Party shall be binding on and be enforceable against, the permitted successors and assigns of such Party; provided that such Party, if it survives, shall remain jointly and severally liable for the performance of such delegated obligations under this Agreement. Any attempted assignment or delegation in violation of this Section 10.3 shall be void and of no effect.
