(c) Subscriber has had an opportunity to fully evaluate an investment in the New Topco Units, is in a financial position to hold the New Topco Units for an indefinite period of time and is able to bear the economic risk and withstand a complete loss of Subscriber’s investment in the New Topco Units.

(e) Subscriber understands that the offer and sale of the New Topco Units have not been registered under the Securities Act or any applicable U.S. state or foreign securities Laws, and that the New Topco Units are being issued in reliance on an exemption from registration, which exemption depends upon, among other things, the bona fide nature of the investment intent and the accuracy of Subscriber’s representations as expressed herein.

(f) Subscriber understands that there will be substantial restrictions on the transferability of the New Topco Units and that on the date of the Subscription Closing and for an indefinite period thereafter there will be no public market for the New Topco Units and, accordingly, Subscriber will not be able to transfer the New Topco Units in case of emergency, if at all (except as permitted by the Topco LP Agreement). In addition, Subscriber understands that the Topco LP Agreement will contain restrictions on the transferability of the New Topco Units and will provide that, in the event that the conditions relating to the transfer of any New Topco Units in such document have not been satisfied, Subscriber will not be able to transfer any such New Topco Units, and unless otherwise specified, Topco LP will not recognize the transfer of any such New Topco Units on its books and records or issue any certificates representing any such New Topco Units, and any purported transfer not in accordance with the terms of the Topco LP Agreement shall be void. As such, Subscriber understands that: (A) if the New Topco Units are certificated, a restrictive legend or legends will be placed on the certificates representing the New Topco Units; (B) a notation will be made in the appropriate records of Topco LP indicating that the New Topco Units are subject to restrictions on transfer and, if Topco LP should at some time in the future engage the services of a securities transfer agent, appropriate stop-transfer instructions will be issued to such transfer agent with respect to the New Topco Units; and (C) Subscriber will sell, transfer or otherwise dispose of the New Topco Units only in a manner consistent with its representations and warranties set forth herein and then only in accordance with the Topco LP Agreement and applicable Laws.

(d) Counterparts; Effectiveness. This Agreement may be signed in any number of counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument.

The exchange of a fully executed Agreement (in counterparts or otherwise) by electronic transmission in . PDF format or by facsimile shall be sufficient to bind the parties to the terms and conditions of this Agreement.

(e) Entire Agreement. This Agreement, the Merger Agreement, the Support Agreements and each of the documents, instruments and agreements delivered in connection with the Contemplated Transactions, including the Company Disclosure Letter, constitute the entire agreement of the parties and supersede all prior agreements and undertakings, both written and oral, among the parties, or any of them, with respect to the subject matter hereof and, except as otherwise expressly provided herein, are not intended to confer upon any other Person any rights or remedies hereunder.

(f) Further Assurances. Each party hereto shall execute and deliver all such further and additional instruments and agreements and shall take such further and additional actions, as may be reasonably necessary or desirable and as reasonably requested by any other party hereto to evidence or carry out the provisions of this Agreement or to consummate the transactions contemplated hereby.

(g) Governing Law; Jurisdiction; Waiver of Jury Trial. Sections 8.7 and 8.10 of the Merger Agreement are hereby incorporated herein by reference, mutatis mutandis.

(h) Notices. All notices and other communications provided for or permitted under this Agreement shall be in writing and deemed to have been duly given and received when delivered by overnight courier or hand delivery, when sent by email (if transmission is confirmed, and each party hereto agrees to promptly confirm if such confirmation is requested) or five days after mailing if sent by registered or certified mail (return receipt requested) postage prepaid, to the parties at the following addresses (or at such other address for any party as specified by like notices).

If to the Company, to the General Counsel and Deputy General Counsel of the Company at the Company’s headquarters.

If to Subscriber, to the last address that the Company has in its personnel records for Subscriber.

(i) Severability. If any term or other provision of this Agreement is held by a court of competent jurisdiction or other authority to be invalid, illegal or incapable of being enforced by any rule of law or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the Contemplated Transactions is not affected in any manner materially adverse to any party. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in a mutually acceptable manner to the end that the Contemplated Transactions are consummated as originally contemplated to the fullest extent possible.

Therefore, the obligations of the parties hereto under this Agreement shall be enforceable by a decree of specific performance if issued by the courts specified in Section 5(g) above, and appropriate injunctive relief may be applied for and granted in connection therewith. Any party seeking an injunction, a decree or order of specific performance or other equitable remedy shall not be required to provide any bond or other security in connection therewith and any such remedy shall be in addition to and not in substitution for any other remedy to which such party is entitled at law or in equity.
