(b)    Notification of Planned Sale Transactions. In the event that a Summit Investor plans to sell Common Stock in a Sale Transaction, such Summit Investor will notify the Corporation in writing as promptly as practicable in advance of such Sale Transaction, and the Corporation will, within three (3) days after receiving such notice from such Summit Investor, notify each Other Holder in writing of the

proposed Sale Transaction, which written notice shall set forth (i) such Other Holder’s Transfer Amount as a result of such Sale Transaction and (ii) the number of shares of Common Stock, if any, that are already transferable by such Other Holder as a result of one or more Transfer Amounts available to such Other Holder as a result of the application of the proviso in the first sentence of Section 4(a).

(c)    Permitted Transfers. The restrictions on transfer set forth in Section 4(a) shall not apply to any Transfer of Common Stock to a Permitted Transferee; provided that the restrictions contained in this Agreement will continue to be applicable to such Common Stock after any Transfer pursuant to this Section 4(c) and such Permitted Transferee shall agree to be a party to this Agreement on the same terms as the transferor and shall sign a joinder to this Agreement in form and substance reasonably acceptable to the Corporation and the Majority Summit Investors. 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).

(d)    Applicability of Restrictions on Transfer. Notwithstanding anything in this Agreement to the contrary, the restrictions on transfer set forth in this Section 4 shall not apply to any shares of Common Stock acquired or received by a Stockholder after the closing of the IPO (other than pursuant to the LLC Agreement), except as a result of a stock split, dividend, or similar transaction on shares of Common Stock held as of the IPO.

(c)    If to any Other Holder, the address then on record with the Company.

or, in each case, to such other address or email address as such party may designate in writing to each party by written notice given in the manner specified herein. All such communications shall be deemed to have been given, delivered or made when so delivered by hand, on the next business day if sent by overnight courier service (with confirmed delivery) or when received if sent by first class mail, or in the case of notice by electronic mail, when the relevant email enters the recipient’s server.

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,

as applicable. Furthermore, each of the Stockholders shall cause any such Permitted Transferee to become a party to this Agreement upon completion of any such permitted transfer.

Section 12.    Amendment and Modification; Waiver.

This Agreement may be amended, modified or waived with the written consent of the Company and the Majority Summit Investors; provided that the definitions of “Permitted Transferees” and “Affiliates” may not be narrowed as it relates to the Other Holders, in each case without the prior written consent of the Other Holders holding a majority of the shares of Common Stock held by all Other Holders. If the terms of any such amendment, modification or waiver requiring the consent of the Summit Investors in accordance with the first sentence of this Section 12 would adversely affect in any material respect the rights and obligations of any Other Holder or group of Other Holders in an adverse manner materially different than the Summit Investors, then such amendment, modification or waiver shall also require the written consent of the holders of a majority of the Common Stock held by all Other Holders so adversely affected.

Section 13.    Severability.

If any provision of this Agreement, or the application of such provision to any Person or circumstance or in any jurisdiction, shall be held to be invalid or unenforceable to any extent, (a) the remainder of this Agreement shall not be affected thereby, and each other provision hereof shall be valid and enforceable to the fullest extent permitted by law, (b) as to such Person or circumstance or in such jurisdiction such provision shall be reformed to be valid and enforceable to the fullest extent permitted by law and (c) the application of such provision to other Persons or circumstances or in other jurisdictions shall not be affected thereby.

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 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.
