if such adjournment or postponement is proposed in compliance with the provisions of Section 8.5 of the Merger Agreement; 

(e)    against any RMT Partner Acquisition Proposal or any RMT Partner Superior Proposal (without regard to the terms of

 (f)    against any
amendment of the Organizational Documents of RMT Partner (other than the RMT Partner Charter Amendment) or other action or agreement of RMT Partner, in each case for which the vote or consent of the applicable class of capital stock of RMT Partner
is required to authorize such action or agreement, that would reasonably be expected to (i) result in a breach of any covenant, representation or warranty or any other obligation or agreement of RMT Partner under the Merger Agreement,

itself not be a sale, transfer or disposition of any Subject Shares prohibited by this Section 2 (and in any such event, the proxy granted pursuant to the Zaslav Agreement shall not become operative) as long as JCM’s
spouse, estate or any trust to which assets of JCM may be transferred upon his death or incapacity continues to own such Subject Shares and agrees to perform his obligations hereunder. Any Transfer in violation of this provision shall be void ab
initio. RMT Partner agrees not to register the Transfer of any certificate or book-entry representing any Subject Shares on the books of RMT Partner unless such Transfer is made in compliance with this Agreement. The foregoing restrictions on
Transfers of Subject Shares shall not prohibit any such Transfers by any Stockholder in connection with the Transactions. 

3.    Non-Solicitation. Each Stockholder hereby agrees, and agrees to cause
his, her or its controlled Affiliates (which, for the avoidance of doubt, does not include RMT Partner) and its and their Representatives not to, take any action which, were it taken by RMT Partner or its Representatives, would violate

shares of capital stock of RMT Partner by reason of any split-up, reverse stock split, recapitalization, combination, reclassification, reincorporation, exchange of shares or the like, the terms “shares
of capital stock of RMT Partner” and “Subject Shares” shall be deemed to refer to and include such shares as well as all such stock dividends and distributions and any securities into which or for which any or all of such shares may
be changed or exchanged or which are received in such transaction.

Stockholder hereby agrees to notify RMT Partner, Remainco and Spinco in writing as promptly as practicable of the number of any additional shares of Pre-Closing RMT Partner Voting Capital Stock of which such


  
 4 













 
Stockholder acquires Beneficial Ownership on or after the date hereof; provided, that any timely filing with the SEC by a Stockholder pursuant to Section 13 or Section 16 of the

permit of, action by, filing with or notification to any Governmental Entity, other than any consent, approval, authorization, permit, action, filing or notification the failure of which to make or obtain would not, individually or in the aggregate,
be reasonably expected to prevent or materially delay the consummation of the Transactions and other than pursuant to the Exchange Act, the Securities Act, the HSR Act or any other Regulatory Approvals required in connection with the Transactions.

 (b)    No Conflicts. Neither the execution and delivery of this Agreement, nor the performance by the

 8
