 17.5. Governing Law; Jurisdiction; Specific Performance. 

(a) This Agreement shall be construed, performed and enforced in accordance with, and governed by, the Laws of the State of Delaware, without
giving effect to any choice or conflict of law provision or rule that would cause the application of the laws of any jurisdiction other than the State of Delaware. Each of the parties hereto irrevocably agrees that any legal action or proceeding
with respect to this Agreement and the rights and obligations arising hereunder, or for recognition and enforcement of any judgment in respect of this Agreement and the rights and obligations arising hereunder brought by the other party(ies) hereto
or its successors or assigns shall be brought and determined exclusively in the Delaware Court of Chancery and any state appellate court therefrom within the State of Delaware, or in the event (but only in the event) that such court does not have
subject matter jurisdiction over such action or proceeding, any state or federal court within the State of Delaware. Each of the parties hereto hereby irrevocably submits with regard to any such action or proceeding for itself and in respect of its
property, generally and unconditionally, to the personal jurisdiction of the courts set forth in this paragraph and agrees that it will not bring any action relating to this Agreement or any of the transactions contemplated by this Agreement in any
court other than such courts. Each of the parties hereto hereby irrevocably waives, and agrees not to assert, by way of motion, as a defense, counterclaim or otherwise, in any action or proceeding with respect to this Agreement, (i) any claim
that it is not personally subject to the jurisdiction of the above named courts, (ii) any claim that it or its property is exempt or immune from jurisdiction of any such court or from any legal process commenced in such courts and (iii) to
the fullest extent permitted by applicable Law, any claim that (A) the suit, action or proceeding in such court is brought in an inconvenient forum, (B) the venue of such suit, action or proceeding is improper or (C) this Agreement,
or the subject matter hereof, may not be enforced in or by such courts. Each of the parties hereto agrees that a final judgment in any action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in
any other manner provided by Law. To the fullest extent permitted by applicable Law, each of the parties hereto hereby consents to the service of process in accordance with Section 17.4; provided, that nothing herein
shall affect the right of any party to serve legal process in any other matter permitted by Law. 
 (b) EACH PARTY HERETO HEREBY ON BEHALF OF
ITSELF AND ITS SUBSIDIARIES IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION OR PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT AND ANY OF THE AGREEMENTS
DELIVERED IN CONNECTION HEREWITH OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY. EACH PARTY HERETO CERTIFIES AND ACKNOWLEDGES THAT (I) NO REPRESENTATIVE, AGENT OR 

  
 16 













 
ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE ANY OF SUCH WAIVERS, (II) IT UNDERSTANDS AND
HAS CONSIDERED THE IMPLICATIONS OF SUCH WAIVERS, (III) IT MAKES SUCH WAIVERS VOLUNTARILY, AND (IV) IT HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 17.5.

 (c) The parties agree that irreparable damage would occur and that the parties would not have any adequate remedy at law in the event that
any of the provisions of this Agreement were not performed, or were threatened not to be performed, in accordance with their specific terms or were otherwise breached and that any defense in any action for specific performance that a remedy at law
would be adequate is hereby waived. It is accordingly agreed that the parties shall be entitled to an injunction or injunctions to prevent breaches or threatened breaches of this Agreement and to enforce specifically the terms and provisions of this
Agreement (in addition to any and all other rights and remedies at law or in equity, and all such rights and remedies shall be cumulative, except, in each case, as may be limited by Section 9.02 of the Merger Agreement). Any requirements for
the securing or posting of any bond in connection with or as a condition to obtaining any such remedy are waived. Each of the parties agrees that it will not oppose the granting of an injunction, specific performance or other equitable relief on the
basis that any other party has an adequate remedy at law or that any award of specific performance is not an appropriate remedy for any person at law or in equity. 

17.6. Interpretation. The section and paragraph headings in this Agreement are for reference purposes only and shall not affect the
meaning or interpretation of this Agreement. The parties have participated jointly in the negotiation and drafting of this Agreement. If any ambiguity or question of intent arises, this Agreement will be construed as if drafted jointly by the
parties and no presumption or burden of proof will arise favoring or disfavoring any party because of the authorship of any provision of this Agreement. 

17.7. Entire Agreement; No Other Representations. This Agreement, the Merger Agreement, the Governance Agreement, the Settlement and
Release Agreement, dated September 9, 2018, by and among CBS, NAI and certain other Persons (as amended by that certain Amendment No. 1 to Settlement and Release Agreement, dated as of the date hereof, the “Settlement
Agreement”) and the Confidentiality Agreement and the exhibits and schedules hereto and thereto contain the entire understanding among the parties hereto with respect to the matters contemplated hereby and supersede and replace all prior
and contemporaneous agreements and understandings, oral or written, with regard to such matters. For the avoidance of doubt, this Agreement does not amend, modify or supersede in any way the Settlement Agreement, which shall remain in full force and
effect. 
 17.8. No Third-Party Beneficiaries. Nothing in this Agreement is intended to confer, or does confer, any rights or remedies
under or by reason of this Agreement on any Persons other than the parties hereto and their respective successors and permitted assigns. 

17.9. Expenses. All fees and expenses incurred in connection with this Agreement and the obligations hereunder, including all legal,
accounting, financial advisory, consulting and all other fees and expenses of third parties incurred by a party in connection with the negotiation and effectuation of the terms and conditions of this Agreement and the transactions contemplated
hereby, shall be the obligation of the respective party incurring such fees and expenses. 

  
 17 













 17.10. Severability. In the event that any part of this Agreement is declared by any
court or other judicial or administrative body to be null, void or unenforceable, all of the other provisions of this Agreement shall remain in full force and effect, with no effect on the validity or enforceability of such other provisions. If any
provision of this Agreement, or the application of such provision to any Person or any circumstance, is invalid or unenforceable, (a) a suitable and equitable provision shall be substituted therefor in order to carry out, so far as may be valid
and enforceable, the intent and purpose of such invalid or unenforceable provision and (b) the remainder of this Agreement and the application of such provision to other Persons or circumstances shall not be affected by such invalidity or
unenforceability, nor shall such invalidity or unenforceability affect the validity or enforceability of such provision, or the application of such provision, in any other jurisdiction. 

17.11. Counterparts. This Agreement may be executed in counterparts, (including by facsimile, “.pdf” files or other electronic
transmission) each of which shall be deemed an original, but all of which when taken together shall constitute the same instrument. 
 17.12.
Affiliated Entities. To the extent that any Controlled Affiliate of any NAI Party is a stockholder of CBS or Viacom, such NAI Party shall cause such Controlled Affiliate to comply with all obligations under this Agreement applicable to the
NAI Parties and the NAI Parties, and in furtherance of the foregoing, if any Controlled Affiliate of an NAI Party becomes a Beneficial Owner of Shares on or after the date hereof, (i) such NAI Party shall give each of CBS and Viacom written
notice thereof in advance of such Controlled Affiliate becoming a Beneficial Owner and (ii) such Controlled Affiliate shall, and the applicable NAI Party shall cause such Controlled Affiliate to, promptly (and in advance of such Controlled
Affiliate becoming a Beneficial Owner, if reasonably practicable) execute a joinder to this Agreement substantially in the form of Annex I, and to execute any and all documents or instruments and take such other actions required, or otherwise
reasonably requested by CBS or Viacom, to ensure that such Controlled Affiliate is subject to the obligations under this Agreement applicable to the NAI Parties and the NAI Parties and that such Shares are subject to this Agreement (provided,
that any failure to execute such documents or instruments or take such other actions shall not affect such obligations hereunder).
