	1.	 Actions With Respect to the Surviving Corporation Board. 

(a) Unless the Surviving Corporation Board determines otherwise with the Requisite Approval, each of the Surviving Corporation and the NAI
Entities shall take such actions as may be necessary to ensure that (A) subject to Section 1(a)(B), the Post-Merger Directors shall constitute the only members of the Surviving Corporation Board until the second
anniversary of the Closing Date, including by taking all actions necessary to recommend such persons for election to the Surviving Corporation Board and to cause such persons to be elected and/or appointed to the Surviving Corporation Board, and
(B) if, at any time prior to the second anniversary of the Closing Date, any member of the Surviving Corporation Board’s service as a director ceases as a result of such director’s removal, death, retirement or resignation or a
vacancy exists by virtue of there being fewer than 13 members of the Surviving Corporation Board at the Effective Time, such vacancy shall be filled as follows: 

(i) if such individual is an NAI Affiliated Director, by an individual designated by the NAI Entities; 

(ii) if such individual is the Chief Executive Officer, such vacancy shall be filled by the new Chief Executive Officer upon
appointment by the Surviving Corporation Board; and 
 (iii) any other vacancy shall be filled by an Unaffiliated Independent
Director approved with the Requisite Approval upon the recommendation of the Surviving Corporation’s nominating and governance committee (acting by a majority vote) following customary public company practices. 

  
 3 

 (b) Each of the NAI Entities agrees that it will not take action that would result in
(i) the Surviving Corporation Board being comprised of less than a majority of Unaffiliated Independent Directors, (ii) the Surviving Corporation’s compensation committee or nominating and governance committee not being comprised of
all Unaffiliated Independent Directors, or (iii) the Surviving Corporation availing itself of the controlled companies exception under the NYSE listing standards or, if the Surviving Corporation is listed on the Nasdaq Global Select Market,
under the Nasdaq Global Select Market listing standards. 
 (c) Each of the NAI Entities agrees that, unless the Surviving Corporation Board
determines otherwise with the Requisite Approval, it will not take any action that would result in the modification, amendment or repeal of, or take any action in contravention of or that conflicts with, (i) from and after the Closing Date
until the second anniversary of the Closing Date, (A) Article XI (other than Section 4(d) thereof) or Section 4 of Article IX of the Bylaws, including by adopting or approving (by vote, written consent or otherwise) any amendment to
the Charter having such effect or (B) Article V or the last sentence of Section 3 of Article IV of the Charter or (ii) from and after the Closing Date until the fifteen month anniversary of the Closing Date, Section 4(d) of
Article XI or Section 14 of Article V of the Bylaws. 
 The Parties acknowledge that Section 5(g) of this
Agreement applies to this Section 1. For the avoidance of doubt, with respect to each action specified above in this Section 1, the NAI Parties shall be obligated to take all lawful steps within
their power and authority (including voting and directing the voting of shares of the Surviving Corporation voting stock under their control) to ensure that such action (including the election as directors of the Surviving Corporation Board of
persons to be nominated for election as directors of the Surviving Corporation Board) occurs as contemplated by this Section 1. The NAI Parties shall not take any action, by written consent or otherwise, to (i) remove
any of the Post-Merger Directors (other than any of the NAI Affiliated Directors) or (ii) increase the size of, or create any additional vacancies on, the Surviving Corporation Board, in the case of each of clauses (i) and (ii), if doing
so would be inconsistent with the terms of this Agreement, the Merger Agreement, the Charter or the Bylaws, until the second anniversary of the Closing Date, except with the Requisite Approval. 

 

	2.	 Extraordinary Transactions. 

The NAI Entities acknowledge and affirm they are open to exploring expressions of interest by third parties in potential business combinations
or other strategic alternatives. As such, until the second anniversary of the Closing Date, the NAI Entities hereby agree to give good faith consideration to any business combination transaction or other strategic alternative involving the Surviving
Corporation that the Unaffiliated Directors determine may be in the best interests of the Surviving Corporation and its stockholders.

	3.	 Ratification. 

(a) To the extent necessary, P. Redstone, SER, Jankowski, Krutick, T. Korff, Andelman, Jacobs and Lewin, in their capacities as current and/or
future Trustees of the Trust, hereby agree that entering into this Agreement is consistent with the terms of the Trust and in the best interests of the Trust and its current, contingent and remainder beneficiaries and on that basis enter into this
Agreement and ratify the decision of SMR to enter into this Agreement as if it were their own. 
 (b) SER, T. Korff, Andelman, Krutick,
Ostheimer and B. Korff, in their capacities as current and/or future directors of NAI and managers of NAIEH, hereby agree that entering into this Agreement is in the best interests of the NAI Entities.

This Agreement shall become effective at the Effective Time. In the event that the Merger Agreement is terminated prior to the Effective Time
in accordance with Section 9.01 thereof, this Agreement shall automatically terminate and be of no further force or effect.

Agreement may not be modified or amended, except (i) for any modification or amendment prior to the Closing, by an instrument in writing signed by all of the Parties adversely affected thereby and (ii) for any modification or amendment
following the Closing, by an instrument in writing signed by all of the Parties and third party beneficiaries adversely affected thereby (provided that if more than one third party beneficiary is adversely affected in the same manner, then
consent of a majority of such third party beneficiaries so affected shall be deemed sufficient to satisfy such requirement); provided that any modification or amendment prior to the second anniversary of the Closing also requires the
Requisite Approval; provided, further, that prompt notice of any modification or amendment shall be given to all Parties; provided, further, that this Agreement may be modified or amended, without a need for an instrument
in writing signed by any Additional Party (and otherwise without the consent thereof or notice thereto), unless such amendment or modification is to an Additional Parties Section in which case an instrument in writing signed by any Additional Party
adversely affected thereby shall be required. 
 (d) Each Party hereby represents and warrants with respect to itself, himself or herself,
that (i) the execution and performance of this Agreement is fully authorized, (ii) with respect to any Party that is a corporation or other entity, the person or persons executing this Agreement have the necessary and appropriate authority

made or obtained by a Party that has not been obtained in order to execute and perform its obligations under this Agreement and (iv) upon the due execution by the other Parties hereto, this
Agreement is a valid, legal, binding and enforceable obligation of such Party. Each Party shall indemnify, defend and hold harmless each other Party from any and all Claims brought against such other Parties arising out of or relating to a breach by
such first Party of any representations, warranties or covenants contained in this Agreement. Each of NAI, NAIEH, the Trust, SMR, SER and the Additional Parties hereby represents and warrants with respect to itself, himself or herself that, since
September 9, 2018, there have been no amendments or modifications to the beneficial ownership, organizational structure or organizational documents of, or appointments, removals or resignations of any of the managers or trustees, as applicable,
of, NAI, NAIEH or the Trust that would, or would reasonably be expected to, impact the ability of such Party to comply with its obligations under the NAI Settlement Agreement or this Agreement or accurately make the representations and warranties
set forth herein. 
 (e) The Parties agree that each Party is entering into this Agreement by its, his or her own free will and not as the
result of any undue influence or other unlawful acts by any other Party or any other person or entity. 
 (f) This Agreement is being entered
into between sophisticated parties, each of which or whom has reviewed the Agreement, had the opportunity to discuss it with its, his or her counsel, and is fully knowledgeable about its terms and conditions. The Parties therefore agree that this
Agreement shall be construed without regard to the authorship of the language and without any presumption or rule of construction in favor of any of them. 

(g) The Parties agree to cooperate in good faith to effect all of the terms of this Agreement. The Parties further agree to execute all papers
and documents and to take such other actions as may be necessary and proper to fulfill the terms and conditions of this Agreement. For the avoidance of doubt, the NAI Parties each hereby agrees, to the extent applicable, to (i) vote all shares
of stock of NAI held by the Trust to fulfill their respective obligations under this Agreement and against any other action, proposal, agreement or transaction that would cause a breach of their respective obligations under this Agreement and
(ii) not commit or agree to take any action or proposal, or take any action (including, without limitation, taking any action by written consent with respect to any shares of the Surviving Corporation voting stock or entering into any
transaction or agreement) (A) to amend or otherwise modify the Charter or Bylaws in any manner that contravenes or conflicts with the terms of this Agreement or the Merger Agreement or (B) that would result in a breach of, or otherwise
violate, any covenant, representation or warranty or any other obligation or agreement of any NAI Party under this Agreement. NAI shall vote (or cause to be voted) all shares of the Surviving Corporation voting stock held by NAI, NAIEH, any
controlled corporate subsidiary or controlled corporate affiliate thereof, or any entity controlled, directly or indirectly, by NAI (excluding any such shares held by the Surviving Corporation and its subsidiaries), to fulfill its respective
obligations under this Agreement and against any other action, proposal, agreement or transaction that would breach its obligations under this Agreement. In the event that any NAI Party transfers, directly or indirectly, any securities of NAI or the
Surviving Corporation to any affiliate (excluding the Surviving Corporation and its subsidiaries) thereof, such NAI Party, as a condition to any such transfer, shall require such affiliate (excluding the Surviving Corporation and its subsidiaries)
to agree in writing to be bound by all of the terms of this Agreement as a NAI Party as such apply to holders of securities of NAI or the Surviving Corporation. The Surviving Corporation hereby agrees to cause all of its subsidiaries to comply with
the terms of this Agreement as if such subsidiaries were parties hereto.

2.1. Each NAI Party agrees that, promptly (and in any event within one Business Day) after the registration statement on Form S-4 pursuant to which the issuance of shares of CBS Common Stock in the Merger will be registered with the SEC (the “Registration Statement”) (in which a joint consent solicitation statement with
respect to the solicitation of written consents from the stockholders of CBS and Viacom in connection with the CBS Stockholder Approval and the Viacom Stockholder Approval, respectively, is included) is declared effective by the SEC, unless a CBS
Adverse Recommendation Change or Viacom Adverse Recommendation Change has occurred prior to such time and has not been rescinded, the NAI Parties shall execute and deliver, or shall cause to be executed and delivered, (i) a written consent
approving the adoption of the Merger Agreement and approving the transactions contemplated thereby, including the Merger, the issuance of the shares of CBS Common Stock contemplated to be issued thereunder and the amendment of CBS’s certificate

Acquisition Proposal (and shall not vote or cause to be voted any other Viacom Shares in favor of any Viacom Acquisition Proposal), (c) the Necessary CBS Shares against any amendment of the CBS Organizational Documents (other than the amendments of
the CBS Organizational Documents contemplated in connection with the Merger as set forth in the Merger Agreement), which amendment would in any manner impede, interfere with, delay, postpone, adversely affect or prevent the consummation of the
Merger or the other transactions contemplated by the Merger Agreement or change in any manner the voting rights of CBS Voting Common Stock (and shall not vote or cause to be voted any other CBS Shares in favor of any such amendment), (d) the
Necessary Viacom Shares against any amendment of the Viacom Organizational Documents (other than the amendments of the Viacom Organizational Documents contemplated in connection with the Merger as set forth in the Merger Agreement), which amendment
would in any manner impede, interfere with, delay, postpone, adversely affect or prevent the consummation of the Merger or the other transactions contemplated by the Merger Agreement or change in any manner the voting rights of Viacom Voting Common
Stock (and shall not vote or cause to be voted any other Viacom Shares in favor of any such amendment), (e) the Necessary CBS Shares against any other action, agreement or transaction involving CBS that is intended, or would reasonably be expected,
to impede, interfere with, delay, postpone, adversely affect or prevent the consummation of the Merger or the other transactions contemplated by the Merger Agreement (and shall not vote or cause to be voted any other CBS Shares in favor of any such
action, agreement or transaction) and (f) the Necessary Viacom Shares against any other action, agreement or transaction involving Viacom that is intended, or would reasonably be expected, to impede, interfere with, delay, postpone, adversely
affect or prevent the consummation of the Merger or the other transactions contemplated by the Merger Agreement (and shall not vote or cause to be voted any other Viacom Shares in favor of any such action, agreement or transaction); provided,
however, that the foregoing clauses (a)–(f) shall not apply to any transaction, proposal or action that is the subject of a CBS Adverse Recommendation Change or a Viacom Adverse Recommendation Change made in accordance with

hereby agrees that, from the date hereof until the record date for the stockholder vote, it shall not allot or issue shares of CBS Voting Common Stock or Viacom Voting Common Stock, as applicable, and shall not grant rights to subscribe for, or
convert any security into, CBS Voting Common Stock or Viacom Voting Common Stock, as applicable. 
 3. Agreement Not to Transfer or
Encumber. Each NAI Party hereby agrees that, from the date hereof until the Expiration Time, it shall not (a) Transfer any Shares if, after completion of such Transfer, the NAI Parties would, at any time, be unable to comply with
Section 2 or (b) deposit any Necessary Shares into a voting trust or enter into a voting agreement or arrangement with respect to any Necessary Shares or grant a proxy or power of attorney with respect thereto (other

otherwise participate in any discussions or negotiations regarding, or furnish to any other Person any non-public information in connection with, or for the purpose of, encouraging or facilitating a CBS
Acquisition Proposal or a Viacom Acquisition Proposal or (c) enter into any letter of intent, memorandum of understanding, agreement in principle, merger agreement, acquisition agreement or other similar agreement constituting a CBS Acquisition
Proposal or a Viacom Acquisition Proposal; provided, however, if CBS, Viacom or any of their respective Representatives receives a CBS Acquisition Proposal or Viacom Acquisition Proposal, as applicable, which CBS Acquisition Proposal
or Viacom Acquisition Proposal, as applicable, did not result from any breach of this Section 4 or the Merger Agreement, and the Board of Directors of CBS or the CBS Transaction Committee, or the Board of Directors of
Viacom or the Viacom Transaction Committee, as applicable, determines in good faith, after consultation with its financial advisor and outside legal counsel, that such CBS Acquisition Proposal or Viacom Acquisition Proposal, as applicable,
constitutes or is reasonably likely to lead to a CBS Superior Proposal or Viacom Superior Proposal, as applicable, then the NAI Parties and their Representatives may engage in or otherwise participate in discussions or negotiations with the Person
or group of Persons making such CBS Acquisition Proposal or Viacom Acquisition Proposal, as applicable, solely to the extent that CBS or Viacom, as applicable, and such NAI Parties and their Representatives, are permitted under the terms of the
Merger Agreement to engage in or otherwise participate in discussions or negotiations with such Person or group of Persons; provided that in such case the initial discussions or negotiations between the NAI Parties or their Representatives
and such Person or group of Persons shall be subject to the consent of CBS or Viacom, whichever made such determination relating to a CBS Superior Proposal or a Viacom Superior Proposal (such consent not to be unreasonably withheld, conditioned or
delayed), the NAI Parties and such Representatives shall coordinate in advance of such discussions with CBS or Viacom, as applicable, with respect to what will be communicated in such discussions or negotiations, and the NAI Parties and such
Representatives shall thereafter keep CBS or Viacom, as applicable, reasonably apprised with respect to any such discussions or negotiations. Each NAI Party agrees that, from the date hereof until the Expiration Time, it shall, and shall cause its
Affiliates and its and their respective Representatives to, immediately cease any solicitation, encouragement, discussions or negotiations with any Persons that may be ongoing with respect to a CBS Acquisition Proposal or a Viacom Acquisition
Proposal, or any inquiry or proposal that would reasonably be expected to lead to a CBS Acquisition Proposal or a Viacom Acquisition Proposal.

copies to NAI of any written comments received from the SEC with respect to the Consent Solicitation Statement and the Registration Statement and promptly advise NAI of any oral comments received from the SEC. Prior to mailing the Consent
Solicitation Statement (or any amendment or supplement thereto) or responding to any comments of the SEC with respect thereto, each of the Merger Agreement Parties shall provide NAI with a reasonable opportunity to review and comment on such
document or response in advance (including the proposed final version of such document or response) and consider in good faith any comments provided by NAI or its representatives with respect to any of the disclosures proposed to be included in such

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, 

  
 17 

 
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. 
 17.10.
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).
