The Stockholder agrees that it will not, directly or indirectly, sell, transfer, assign, pledge, encumber or otherwise dispose of any of the Shares, or any interest therein, or any other securities convertible into or exchangeable for King Common Stock (including the Derivative Securities), or any voting rights with respect thereto or enter into any contract, option or other arrangement or understanding with respect thereto (including any voting trust or agreement and the granting of any proxy), other than: (a) as expressly required by the Loan Documents, as in effect on the date hereof, or (b) with the prior written consent of Crown. The Stockholder hereby agrees to, subject to the terms of the Loan Documents, authorize and request King to notify its transfer agent that there is a stop transfer order with respect to all of the Shares and that this Agreement places limits on the voting of the Shares.

Unless and until the termination of this Agreement pursuant to paragraph 14, at every meeting of the stockholders of King called (whether annual or special), and at every postponement or adjournment thereof, the Stockholder irrevocably and unconditionally agrees to (a) appear at such meeting or otherwise cause all of the Shares to be counted as present thereat for purposes of calculating a quorum and (b) vote all of the Shares entitled to be voted thereat or to cause all of the Shares to be voted thereat (unless otherwise subject to any enforcement action in respect of the Shares held as collateral under the Loan Documents): (i) in favor of the Share Issuance and (ii) against (A) any proposal made in opposition to the Share Issuance, the adoption of the Merger Agreement or that is intended, that could reasonably be expected, or the effect of which could reasonably be expected, to impede, interfere with, delay, postpone, discourage, adversely affect, compete or be inconsistent with the Merger, the Share Issuance or any other transaction contemplated by the Merger Agreement, (B) any Acquisition Proposal and (C) any action or agreement that would result in a breach of any representation, warranty, covenant or agreement or any other obligation of King or King Sub under the Merger Agreement or of the Stockholder under this Agreement.

Notwithstanding paragraph 3, if the King Board (at the recommendation of the Special Committee) effects a Change of Recommendation in compliance with the terms and conditions of Section 7.2 of the Merger Agreement in connection with a Superior Proposal, the obligation of the Stockholder to vote the Shares in the manner set forth in paragraph 3(b) shall apply only with respect to the lesser of (a) all of the Shares of which the Stockholder is the record or beneficial owner and (b) such portion of the Shares equal to 35% of the shares of King Common Stock in the aggregate.

In furtherance of the agreements contained in paragraph 3 of this Agreement and as security for this Agreement, the Stockholder hereby irrevocably and unconditionally appoints Danielle Hunter and Jan Kees van Gaalen (the “Grantees”), and each of them individually, as the sole and exclusive attorneys-in-fact and proxies of the Stockholder, for and in the name, place and stead of the Stockholder, with full power of substitution and resubstitution, to vote, grant a consent or approval in respect of, or execute and deliver a proxy to vote, the Shares, subject to (a) the terms and conditions of paragraph 4, (b) the termination of this Agreement pursuant to paragraph 14 or (c) the lender commencing an enforcement action in respect of the Shares held as collateral under the Loan Documents, (i) in favor of the Share Issuance, (ii) against any matter referred to in paragraph 3(b)(ii) of this Agreement and (iii) in the discretion of the Grantees, with respect to any proposed postponements or adjournments of any annual or special meeting of the stockholders of King held in connection with any of the foregoing. The Stockholder hereby affirms that the irrevocable proxy set forth in this paragraph 5 is given in connection with, and in consideration of, the execution of the Merger Agreement by Crown, King and King Sub, and that such irrevocable proxy is given to secure the performance of the duties of the Stockholder under this Agreement. The Stockholder hereby further affirms that the proxy granted in this paragraph 5 is coupled with an interest and may under no circumstances be revoked. The Stockholder hereby ratifies and confirms all that the Grantees may lawfully do or cause to be done by virtue hereof. The proxy contained herein with respect to shares of King Common Stock is intended to be irrevocable in accordance with the provisions of Section 212(e) of the DGCL and is limited to the Shares owned by the Stockholder at the time the vote is to occur, pursuant to the terms and conditions set forth in any proxy statement.

Each of the Stockholder and Cerberus agrees that it shall comply in all respects with, and take no action inconsistent with, the terms, conditions, restrictions and obligations set forth in Section 7.2 of the Merger Agreement applicable to Representatives, and Stockholder acknowledges and agrees that it is a “Representative” of King for the purpose of Section 7.2 of the Merger Agreement.

Prior to the Effective Time, to the extent that any Crown stockholders have registration rights under that certain Registration Rights Agreement, dated as of January 6, 2017, by and among Crown and certain Crown stockholders named therein (the “Crown Registration Rights Agreement”), Crown, Cerberus and the Stockholder shall use reasonable best efforts (which efforts shall include negotiating in good faith with each other and with King) to enter into an agreement among King, the Crown stockholders party to the Crown Registration Rights Agreement, Cerberus and the Stockholder resolving any inconsistencies between the registration rights granted pursuant to the Crown Registration Rights Agreement and the King Stockholders Agreement.

The parties acknowledge and agree that nothing contained in this Agreement shall restrict, limit or prohibit any Affiliate of the Stockholder or Cerberus from exercising (in his or her capacity as a member of the King Board (or the New Board, as applicable)) his or her rights or fiduciary duties as such a director.

Each of the Stockholder and Cerberus represents and warrants that it has all necessary power and authority to enter into this Agreement, and that this Agreement is the legal, valid and binding agreement of the Stockholder and Cerberus (as applicable) and is enforceable against the Stockholder and Cerberus (as applicable) in accordance with its terms.

Each of the Stockholder and Cerberus represent and warrants that as of the date of this Agreement, no Affiliate of the Stockholder or Cerberus (as applicable) owns beneficially or of record any Shares or Derivative Securities. In the event that any Affiliate of the Stockholder or Cerberus acquires record or beneficial ownership of any Shares or Derivative Securities after the execution of this Agreement, the Stockholder or Cerberus (as applicable) shall cause such Affiliate to enter into a joinder to this Agreement, in a form and substance satisfactory to Crown, requiring such Shares or Derivative Securities to be subject to this Agreement to the same extent that such Shares or Derivative Securities would have been had they been owned by the Stockholder or Cerberus.

This Agreement shall terminate on the earlier of (a) termination of the Merger Agreement in accordance with its terms or (b) the day following the Effective Time; provided, however, that unless the Merger Agreement is terminated in accordance with its terms, paragraph 6 shall terminate upon the expiration of the Standstill Period and paragraph 7 shall terminate forty-five days after the Effective Time.
