At least fifteen (15) days prior to the Transfer of Common Stock pursuant to this Section 4(c), the transferee(s) will deliver a written notice to the Corporation, which notice shall disclose in reasonable detail the identity of such transferee(s).

Section 11. Assignment.

Except as otherwise provided herein, all of the terms and provisions of this Agreement shall be binding upon, shall inure to the benefit of and shall be enforceable by the respective successors and permitted assigns of the parties hereto. This Agreement may not be assigned (by operation of law or otherwise) without the express prior written consent of the other parties hereto, and any attempted assignment, without such consents, will be null and void; provided, however, that each of the Stockholders is permitted to assign this Agreement to its respective Permitted Transferees in connection with a permitted transfer thereto of Common Units, Class A Common Stock or Class B Common Stock,

Section 13. Severability.

Section 14. Counterparts.

This Agreement may be executed in any number of counterparts and signatures may be delivered by facsimile, each of which may be executed by less than all parties, each of which shall be enforceable against the parties actually executing such counterparts, and all of which together shall constitute one instrument.

Section 15. Further Assurances.

At any time or from time to time after the date hereof, the parties hereto agree to cooperate with each other, and at the request of any other party, to execute and deliver any further instruments or documents and to take all such further action as any other party may reasonably request in order to evidence or effectuate the provisions of this Agreement and to otherwise carry out the intent of the parties hereunder.

Section 16. Titles and Subtitles.

The descriptive headings of this Agreement are inserted for convenience only and do not constitute a part of this Agreement.

Section 17. Representations and Warranties.

securities of Holdings, Blocker, or the Aggregator, as applicable, set forth on Schedule III hereto as of the date hereof.

(b) The Corporation represents and warrants to each other party hereto that (i) the Corporation is duly authorized to execute, deliver and perform this Agreement; (ii) this Agreement has been duly authorized, executed and delivered by the Corporation and is a valid and binding agreement of the Corporation, enforceable against the Corporation in accordance with its terms; and (iii) the execution, delivery and performance by the Corporation of this Agreement does not violate or conflict with or result in a breach by the Corporation of or constitute (or with notice or lapse of time or both constitute) a default by the Corporation under the Charter or Bylaws, any existing applicable law, rule, regulation, judgment, order, or decree of any governmental authority exercising any statutory or regulatory authority of any of the foregoing, domestic or foreign, having jurisdiction over the Corporation or any of its Subsidiaries or any of their respective properties or assets, or any agreement or instrument to which the Corporation or any of its Subsidiaries is a party or by which the Corporation or any of its Subsidiaries or any of their respective properties or assets may be bound.

Section 18. No Strict Construction.

This Agreement shall be deemed to be collectively prepared by the parties hereto, and no ambiguity herein shall be construed for or against any party based upon the identity of the author of this Agreement or any provision hereof.

Section 19. Entire Agreement.

Except as otherwise expressly set forth herein, this Agreement and the Registration Rights Agreement embody the complete agreement and understanding among the parties hereto with respect to the subject matter hereof and supersede and preempt any prior understandings, agreements or representations by or among the parties, written or oral, which may have related to the subject matter hereof in any way, including the LLC Agreement, the Blocker LLC Agreement, and the Aggregator LLC Agreement, which agreements will terminate following and conditioned upon the closing of the IPO. For the avoidance of doubt, this Agreement shall not supersede or preempt any obligations of any Stockholder under any “lock up” agreement executed by any Stockholder in connection with any registered offering of Common Stock from time to time during the term of this Agreement.
