WHEREAS, as a condition to the willingness of the Company and Parent to enter into the Merger Agreement and as an inducement and in consideration therefor, the Company and Parent have required that the Stockholder, and the Stockholder has agreed to, enter into this Agreement.

NOW, THEREFORE, in consideration of the foregoing and the mutual covenants and agreements herein contained, and intending to be legally bound hereby, the Stockholders, the Company and Parent hereby agree as follows:

1. Agreement to Tender.

1.1 The Stockholder agrees to validly tender or cause to be validly tendered in the Offer all of the Owned Shares (less and excluding the Rollover Shares) and any additional shares of Common Stock or other voting securities of the Company acquired by the Stockholder or its respective controlled Affiliates after the date hereof and prior to the Termination Date (as adjusted pursuant to Section 13, collectively, the “Covered Shares”), pursuant to and in accordance with the terms of the Offer. Without limiting the generality of the foregoing, as promptly as practicable after, but in no event later than ten (10) Business Days after, the commencement of the Offer, the Stockholder shall (a) deliver pursuant to the terms of the Offer (i) a letter of transmittal with respect to all of the Covered Shares complying with the terms of the Offer, (ii) one or more certificate(s) representing all of the Covered Shares or an “agent’s message” (or such other evidence, if any, of transfer as the depository may reasonably request) in the case of any Covered Shares in the form of book-entry shares, and (iii) all other documents or instruments required to be delivered by the Stockholder pursuant to the terms of the Offer, and (b) instruct the Stockholder’s broker or such other Person that is the holder of record of any Covered Shares to tender all such Covered Shares pursuant to and in accordance with this Section 1.1 and the terms of the Offer. The Stockholder agrees that once the Covered Shares are tendered, the Stockholder will not withdraw any of the Covered Shares from the Offer until the Termination Date.

1.2 If (i) the Offer is terminated or withdrawn by Parent or Merger Sub, or (ii) the Termination Date occurs prior to the Offer Acceptance Time, Parent and Merger Sub shall promptly return, or cause any depository acting on behalf of Parent and Merger Sub to return, all of the Covered Shares tendered by the Stockholder in the Offer to the Stockholder.

2. Agreement to Vote the Voting Shares; Proxy.

2.1 Beginning on the date hereof until the Termination Date (as defined below), at every meeting of the Company’s stockholders, including any postponement, recess or adjournment thereof, or in any other circumstance, however called, the Stockholder agrees to, and if applicable, to cause its controlled Affiliates to, affirmatively vote (including via proxy) or execute consents, with respect to (or cause to be voted (including via proxy) or consents to be executed with respect to) all of the Owned Shares and any additional shares of Common Stock or other voting securities of the Company acquired by the Stockholder or its respective controlled Affiliates after the date hereof and prior to the Termination Date (as adjusted pursuant to Section 13, collectively, the “Voting Shares”) against (a) any proposal, action or agreement that would reasonably be expected to result in a breach of any covenant, representation or warranty or other obligation or agreement of the Company contained in the Merger Agreement or that would reasonably be expected to result in any condition set forth in the Merger Agreement not being satisfied or not being fulfilled prior to the Termination Date, (b) any Acquisition Proposal, (c) any reorganization, dissolution, liquidation, winding up or similar extraordinary transaction involving the Company (except as contemplated by the Merger Agreement) and (d) any other action, agreement or proposal which would reasonably be expected to prevent, materially impede or materially delay the consummation of the Transactions or any of the other transactions contemplated by the Merger Agreement (collectively, the “Supported Matters”). The Stockholder agrees to, and agrees to cause its applicable controlled Affiliates to, be present, in person or by proxy, at every meeting of the Company’s stockholders, including any postponement, recess or adjournment thereof, or in any other circumstance, however called, to vote on the Supported Matters (in the manner described in this Section 2.1) so that all of the Voting Shares will be counted for purposes of determining the presence of a quorum at each such meeting, or otherwise cause the Voting Shares to be counted as present thereat for purposes of establishing a quorum at each such meeting. For the avoidance of doubt, except with respect to the obligations hereunder with respect to the Supported Matters, the Stockholder shall be entitled to vote the Voting Shares in its sole discretion. The Stockholder shall not take any action that would reasonably be expected to prevent, materially impair or materially delay the consummation of the transactions contemplated by this Agreement or the Merger Agreement.

2.2 Proxy. In the event, but only in the event, that any Stockholder fails to comply with any of its obligations set forth in Section 2.1, then the Stockholder hereby irrevocably appoints, as its proxy and attorney-in-fact, any duly elected officer of Parent, and each of them individually, with full power of substitution and resubstitution, to vote the Stockholder’s Voting Shares (to the extent such Voting Shares are entitled to so vote) in accordance with Section 2.1 at any Company stockholder meeting (including any postponement, recess or adjournment thereof) at which any Supported Matters are to be considered; provided, however, for the avoidance of doubt, that the Stockholder shall at all times retain the right to vote the Stockholder’s Voting Shares (or to direct how such Voting Shares shall be voted) in the Stockholder’s sole discretion on matters other than Supported Matters. This proxy is coupled with an interest, is (or will be, as applicable) given as an additional inducement to Parent to enter into this Agreement and the Merger Agreement and shall be irrevocable prior to the Termination Date, at which time any such proxy shall terminate. Parent may terminate or waive its rights to enforce this proxy with respect to any Stockholder at any time at its sole election by written notice provided to the applicable Stockholder. For purposes of this Section 2.2, a Stockholder will be deemed to have failed to comply with any of its obligations set forth in Section 2.1 if it has not submitted a proxy to the proxyholder appointed by the Company in connection with any Company stockholder meeting called to vote on any of the Supported Matters to vote consistent with such obligations by the day that is one (1) Business Day prior to the applicable Company stockholder meeting. Notwithstanding anything to the contrary in this Section 2.2, nothing herein shall prevent the Stockholder from making any Transfers permitted under Section 5.1 or as set forth elsewhere in this Agreement to its Affiliates, provided that such Affiliates agree to be bound by the terms of this Agreement, including Section 1.1 and this Section 2.2, with respect to the Transferred Voting Shares pursuant to a Joinder (as defined below).

3. Rollover.

3.1 Contribution and Exchange. On the terms set forth herein and subject to Section 3.2, Section 3.3, Section 3.4 and Section 3.5:

(a) The Stockholder agrees and covenants to Parent that it will, at the Exchange Time, contribute, assign, transfer, convey and deliver (or cause to be contributed, assigned, transferred, conveyed and delivered) to Topco all of the Rollover Shares, free and clear of any and all Liens (including any restriction on the right to vote, sell or otherwise dispose of the Rollover Shares), except as may exist by reason of this Agreement, the Merger Agreement and applicable securities laws, and each of Sponsor and Parent agrees and covenants to the Stockholder to cause Topco to exchange such Rollover Shares for the issuance by Topco to the Stockholder of, at the Exchange Time, the Exchange Interests (the “Exchange”), provided that nothing herein shall affect any Stockholder’s right to receive the Offer Price for any Owned Shares that are not Rollover Shares. No Sponsor Topco Interests issued prior to or in connection with the Transactions shall be issued at a lower price per share than the Sponsor Topco Interests issued hereunder.

(b) The Stockholder shall have the right, in its sole discretion, to designate in writing to Parent at any time prior to the Exchange Time, the specific Owned Shares held by the Stockholder that are the Rollover Shares hereunder.

(d) Notwithstanding anything to the contrary set forth herein or in the Interim Investors Agreement, the Stockholder may elect prior to the Offer Acceptance Time by written notice to the other Investors (as defined in the Interim Investors Agreement) that it elects to replace all or a portion of its Rollover Shares with an equity investment indirectly in Parent on the same terms as the Investors providing an Equity Commitment (as defined in the Interim Investors Agreements), in which case the parties shall enter into documentation (including amendments to this Agreement and the Interim Investors Agreement and entry into an equity commitment letter) to effect the foregoing prior to the Offer Acceptance Time.

3.2 Conditions to Exchange. The obligations of the Stockholder, Topco and Parent to consummate the Exchange at the Exchange Time are subject to the satisfaction (or waiver by the Stockholder or such other party set forth below in writing) of the following conditions:

(a) (i) The satisfaction, or written waiver (to the extent permitted) by Parent, of all conditions to the obligations of the Buyer Parties to consummate the Offer and the transactions contemplated by the Merger Agreement that are to occur on the Closing Date as set forth in Annex A of the Merger Agreement (other than those conditions that by their terms are to be satisfied at the Offer Acceptance Time, but subject to the satisfaction or written waiver by Parent (to the extent permitted thereunder) of such conditions), (ii) the substantially contemporaneous or prior funding of the Equity Financing and, if applicable, the Debt Financing and (iii) the substantially contemporaneous consummation of the Merger at the Effective Time and (iv) the substantially contemporaneous consummation of the contribution of Rollover Shares in exchange for Exchange Interests pursuant to and in accordance with the terms and conditions (and defined terms) of the Other Support/Investment Agreements (as defined below).

(b) Solely for the benefit of Parent, the representations and warranties made by the Stockholder in Section 7.1 through Section 7.8 of this Agreement shall be true and correct as of the Exchange Time as if made at and as of the Exchange Time, except for such failures to be true and correct as would not reasonably be expected, individually or in the aggregate, to (i) prevent or materially impair or materially delay the consummation of the Exchange on the terms set forth herein or (ii) be materially adverse to Parent.

(d) Solely for the benefit of the Stockholder, the representations and warranties made by Parent in Section 9.1 through Section 9.7 of this Agreement shall be true and correct as of the Exchange Time as if made at and as of the Exchange Time, except for such failures to be true and correct as would not reasonably be expected, individually or in the aggregate, to (i) prevent or materially impair or materially delay the consummation of the Exchange on the terms set forth herein or (ii) be materially adverse to the Stockholder;

(h) No law enacted, entered, promulgated, enforced or issued by any Governmental Authority shall be in effect preventing the consummation of, or otherwise making illegal, the Exchange.

3.3 Failure to Consummate the Offer. In the event that after the Exchange the Offer fails to be consummated for any reason whatsoever and the Merger Agreement is terminated in accordance with its terms, the parties hereto agree that, concurrently with such termination of the Merger Agreement, automatically and without any further action of the parties hereto, each of Sponsor and Parent shall cause Topco to assign, transfer, convey and deliver to the Stockholder the Rollover Shares, free and clear of any and all Liens (including any restriction on the right to vote, sell or otherwise dispose of the Rollover Shares), except as may exist by reason of this Agreement and applicable securities laws, and the Stockholder shall assign, transfer, convey and deliver to Topco the Exchange Interests issued to the Stockholder, free and clear of any and all Liens (including any restrictions on the right to vote, sell or otherwise dispose of the Exchange Interests) except as may exist by reason of this Agreement and applicable securities laws. In such event, each party hereto shall, as promptly as practicable, provide all such cooperation as the other parties hereto may reasonably request in order to ensure that such assignments, transfers, conveyances and deliveries have occurred and been made effective. It is intended that the consummation of the transactions described in this Section 3.3 shall constitute a rescission of the Exchange to the extent permitted under applicable law for U.S. federal and applicable state and local income tax purposes.

3.4 Tax Treatment.

(a) Each of Topco, Parent, the Sponsor and the Stockholder intends that, for U.S. federal (and applicable state and local) income tax purposes, each Exchange qualify as a contribution of property to a partnership in exchange for an equity interest in such partnership in which no gain or loss is recognized under Section 721(a) of the Code and the Parent Contribution qualify as an exchange in which no gain or loss is recognized under Section 351(a) of the Code (the “Intended Tax Treatment”). Each of the Stockholders, Parent, the Sponsor and Topco, as applicable, shall prepare and file (and shall cooperate in the preparation and filing of, as reasonably requested) all Tax Returns in a manner consistent with the Intended Tax Treatment and shall not take any position inconsistent with the Intended Tax Treatment in connection with any tax matters, in each case, unless otherwise required by a “determination” within the meaning of Section 1313(a) of the Code.

(b) As of the Effective Time, for U.S. federal income tax purposes, Parent shall be classified as a domestic corporation and Topco shall be classified as a domestic partnership.

3.5 Structure. References to Parent in the foregoing provisions of this Section 3 shall be deemed to refer to Topco, which receives the Rollover Shares and in turn contributes them, directly or indirectly, to Parent, as the context requires based on the holding company structure of Parent and the Sponsor.

3.6 Termination. Neither Parent nor the Stockholder shall be permitted to terminate its obligations under this Section 3 without the prior written consent of the Parent, in the case of any termination by the Stockholder, or the Stockholder, in the case of any termination by Xxxxxx (it being understood that this Section 3 shall also be terminated upon any termination of this Agreement pursuant to Section 4).

4. Termination. This Agreement shall terminate automatically and without further action of the parties hereto upon the earliest to occur of: (i) the valid termination of the Merger Agreement in accordance with its terms, (ii) the Effective Time, (iii) any modification, waiver or amendment to any term or provision of the Offer or the Merger Agreement that is effected without the Stockholder’s prior written consent and that (x) reduces the Offer Price or changes the form of consideration being offered to Company Stockholders under the Offer, imposes any non-immaterial conditions, requirements or restrictions on any Stockholder’s right to receive the cash consideration payable to the Stockholder with respect to shares of Company Common Stock owned by the Stockholder (other than the Rollover Shares) pursuant to the Offer or that materially delays the timing of any such payment after the Offer Acceptance Time or (y) would require the consent of the Stockholder under the Interim Investors Agreement without having received such consent (the earliest such date set forth in clauses (i) through (iii), the “Termination Date”); provided, that the termination of this Agreement shall not prevent any party hereto from seeking any remedies (at law or in equity) against any other party hereto for that party’s Willful and Material Breach of this Agreement that may have occurred on or before such termination (it being acknowledged and agreed that, for the avoidance of doubt, that for purpose of this Agreement references in the definition of Willful and Material Breach to “this Agreement” shall refer to this Agreement and not to the Merger Agreement).

5. Certain Covenants.

5.1 Transfers. Beginning on the date hereof until the Termination Date, the Stockholder hereby covenants and agrees that, except as expressly contemplated by this Agreement, the Stockholder shall not, shall cause its controlled Affiliates not to, and shall direct its other Affiliates and its and its Affiliates’ Representatives not to, directly or indirectly, (a) tender any Voting Shares into any tender or exchange offer (other than the Offer), (b) offer, sell, transfer, assign, exchange, pledge, hypothecate, hedge, gift, loan, encumber or otherwise dispose of (collectively, “Transfer”) or enter into any Contract, option, agreement, understanding or other arrangement with respect to the Transfer of, any Voting Shares or beneficial ownership, voting power or any other interest thereof or therein (including by operation of law), (c) grant any proxies or powers of attorney, deposit any Voting Shares into a voting trust or enter into a voting or other agreement with respect to any Voting Shares that is inconsistent with this Agreement, (d) take an action that would reasonably be expected to prevent or materially impair or materially delay the consummation of the transactions contemplated by this Agreement or the Merger Agreement or (e) commit or agree to take any of the foregoing actions.

Notwithstanding anything to the contrary in this Agreement, but subject to the final sentence of this Section 5.1, any Stockholder may transfer any or all of the Voting Shares, in accordance with applicable law, to the Stockholder’s Affiliates (provided, that, prior to and as a condition to the effectiveness of such Transfer, each Person to whom any of such Voting Shares or any interest in any of such Voting Shares is or may be transferred shall have executed and delivered to Parent a counterpart of this Agreement in a form reasonably acceptable to Parent pursuant to which such Affiliate shall be bound by all of the terms and provisions hereof and deliver an irrevocable proxy in the form of Section 2.2 in which case such Affiliate shall be deemed a Stockholder hereunder, the “Joinder”). From the date hereof until the Exchange Time, the Stockholder shall retain a sufficient number of Rollover Shares to effect the Exchange in accordance with Section 3.1. Notwithstanding anything to the contrary in this Agreement, no Transfer shall be permitted if it results in the conversion of shares of Class B Common Stock to shares of Class A Common Stock under the Charter.

5.2 Other Stockholder Arrangements. Each of the Company and Parent covenants and agrees that it will not, and will cause each of its respective Affiliates not to, amend, modify, waive or terminate any provision of any Support Agreement entered into by and between Parent and the Company, on the one hand, and any Co-Investor (as defined in the Interim Investors Agreement) other than the Stockholder, on the other hand (each, an “Other Support/Investment Agreement”), or enter into any other arrangements, agreement (including side letters) or understandings, whether written or oral, with any Co-Investor other than the Stockholder (“Side Arrangements”) without the prior written consent of the Stockholder, excluding the Interim Investors Agreement.

9.3 Consents. No consent, approval, order or authorization of, or registration, declaration or, (except as required by the rules and regulations promulgated under the Exchange Act, the Securities Act, or state securities, takeover and “blue sky” laws) filing with, or notification to any Governmental Authority or any other Person, is required by or with respect to Parent in connection with (a) the execution and delivery of this Agreement, (b) the performance of Parent of its covenants and obligations under this Agreement, or (c) the consummation by Parent of the transactions contemplated hereby, except as would not, individually or in the aggregate, reasonably be expected to restrict in any material respect, or prohibit or impair in any material respect, the consummation of the Transactions or the performance by Parent of its obligations under this Agreement.

9.4 Absence of Litigation; Orders.

Parent is not subject to any order of any kind or nature that would prevent or materially delay the ability of Parent to perform in all material respects its covenants and obligations pursuant to this Agreement.

12. Waiver of Appraisal and Dissenter Rights and Certain Other Actions. The Stockholder hereby irrevocably and unconditionally waives, to the fullest extent of applicable law, and agrees to cause to be waived and not to assert any appraisal rights, any dissenter’s rights and any similar rights under Section 262 of the DGCL or otherwise with respect to the Voting Shares with respect to the Transactions, the other transactions contemplated by the Merger Agreement and the Offer.

16. Interpretation. Where a reference in this Agreement is made to a section or exhibit, such reference shall be to a section of or exhibit to this Agreement unless otherwise indicated. If a term is defined as one part of speech (such as a noun), it shall have a corresponding meaning when used as another part of speech (such as a verb). Unless the context of this Agreement clearly requires otherwise, words importing the masculine gender shall include the feminine and neutral genders and vice versa, and the definitions of terms contained in this Agreement are applicable to the singular as well as the plural forms of such terms. The words “includes” or “including” shall mean “including without limitation,” the words “hereof,” “hereby,” “herein,” “hereunder” and similar terms in this Agreement shall refer to this Agreement as a whole and not any particular section or article in which such words appear, the word “extent” in the phrase “to the extent” shall mean the degree to which a subject or other thing extends and such phrase shall not mean simply “if,” any reference to a law shall include any rules and regulations promulgated thereunder, in the case of such law or regulation as from time to time amended, modified or supplemented. Each reference to a “wholly owned Subsidiary” or “wholly owned Subsidiaries” of a Person shall be deemed to include any Subsidiary of such Person where all of the equity interests of such Subsidiary are directly or indirectly owned by such Person (other than directors qualifying shares, nominee shares or other equity interests that are required by law or regulation to be held by a director or nominee).

17. Entire Agreement. This Agreement and the documents and instruments and other agreements entered into in connection herewith by any of the parties hereto and the Merger Agreement collectively constitute the entire agreement with respect to the subject matter hereof, and supersede all other prior agreements, understandings, representations and warranties both written and oral, among the parties hereto with respect to the subject matter hereof, including the Original Support Agreement (which Original Support Agreement is hereby terminated in its entirety, effective as of the date hereof, pursuant to Section 2.6 of the Original Support Agreement).

18. No Third-Party Beneficiaries. This Agreement shall be binding upon and inure solely to the benefit of the parties hereto and their respective successors and permitted assigns, and nothing in this Agreement, express or implied, is intended to or shall confer upon any other Person any right, benefit or remedy of any nature whatsoever under or by reason of this Agreement.

19. Governing Law; Waiver of Jury Trial. This Agreement is governed by, interpreted, construed and enforced in accordance with the laws of the State of Delaware. Any and all claims, controversies and causes of action arising out of or relating to this Agreement, whether sounding in contract, tort or statute, shall be governed by the internal laws of the State of Delaware, including its statutes of limitations, without giving effect to any conflict-of-laws or other rules that would result in the application of the laws or statutes of limitations of a different jurisdiction. Each of the parties (i) irrevocably consents to the service of the summons and complaint and any other process (whether inside or outside the territorial jurisdiction of the Chosen Courts) in any Legal Proceeding arising out of or relating to this Agreement, for and on behalf of itself or any of its properties or assets, in accordance with Section 15 or in such other manner as may be permitted by applicable law, but nothing in this Section 19 will affect the right of any party to serve legal process in any other manner permitted by applicable law; (ii) irrevocably and unconditionally consents and submits itself and its properties and assets in any Legal Proceeding to the exclusive general jurisdiction of the Chosen Courts in the event that any dispute or controversy arises out of or relates to this Agreement; (iii) irrevocably and unconditionally agrees that it will not attempt to deny or defeat such personal jurisdiction by motion or other request for leave from any Chosen Court; (iv) agrees that any Legal Proceeding arising out of or relating to this Agreement will be brought, tried and determined only in the Chosen Courts; (v) irrevocably and unconditionally waives any objection that it may now or hereafter have to the venue of any such Legal Proceeding in the Chosen Courts or that such Legal Proceeding was brought in an inconvenient court and agrees not to plead or claim the same; and (vi) agrees that it will not bring any Legal Proceeding arising out of or relating to this Agreement in any court other than the Chosen Courts. Each of the parties agrees that a final judgment in any Legal Proceeding in the Chosen Courts will be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by applicable law. EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY THAT MAY ARISE PURSUANT TO THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE EACH PARTY IRREVOCABLY AND UNCONDITIONALLY WAIVES TO THE FULLEST EXTENT PERMITTED BY LAW ANY RIGHT THAT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LEGAL PROCEEDING (WHETHER FOR BREACH OF CONTRACT, TORTIOUS CONDUCT OR OTHERWISE) DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT, AND THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT. EACH PARTY CERTIFIES AND AGREES THAT (a) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER; (b) IT UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER; (c) IT MAKES THIS WAIVER VOLUNTARILY; AND (d) IT HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 19.

20. Assignment; Successors. Other than as provided herein, neither this Agreement nor any of the rights, interests or obligations under this Agreement (including those set forth in Section 3.1(a)) may be assigned, delegated or transferred, in whole or in part, by operation of law or otherwise, by any party hereto without the prior written consent of the other parties hereto, and any such assignment without such prior written consent shall be null and void. Subject to the preceding sentence, this Agreement will be binding upon, inure to the benefit of, and be enforceable by, the parties hereto and their respective successors and assigns.

21. Enforcement. The parties hereto agree that irreparable damage for which monetary damages, even if available, would not be an adequate remedy would occur in the event that the parties hereto do not perform the provisions of this Agreement (including any party hereto failing to take such actions that are required of it hereunder in order to consummate this Agreement) in accordance with its specified terms or otherwise breach such provisions. For the avoidance of doubt, the parties hereto acknowledge and agree that (a) the parties hereto will be entitled, in addition to any other remedy to which they are entitled at law or in equity, to an injunction, specific performance and other equitable relief to prevent breaches (or threatened breaches) of this Agreement or to enforce specifically the terms and provisions hereof and without bond or other security being required, (b) if any party hereto is seeking injunctive relief, specific performance or other equitable relief pursuant hereto, the other parties hereto will not assert that a remedy of monetary damages would provide an adequate remedy for such breach and (c) the right of specific enforcement is an integral part of the transactions contemplated hereby and without that right, none of the Company, Parent or the Stockholder would have entered into this Agreement. Notwithstanding the foregoing, nothing herein shall in any way limit a party’s right to pursue a claim for monetary damages arising out of a breach of this Agreement.

22. Non-Recourse. This Agreement may only be enforced against, and any Action based upon, arising out of, or related to this Agreement, or the negotiation, execution or performance of this Agreement, may only be brought against the entities that are expressly named as parties hereto and then only with respect to the specific obligations set forth herein with respect to such party. No past, present or future director, officer, employee, incorporator, manager, member, general or limited partner, stockholder, equityholder, controlling person, Affiliate, agent, attorney or other Representative of any party hereto or any of their successors or permitted assigns or any direct or indirect director, officer, employee, incorporator, manager, member, general or limited partner, stockholder, equityholder, controlling person, Affiliate, agent, attorney, Representative, successor or permitted assign of any of the foregoing (each, a “Non-Recourse Party”), shall have any liability to any Stockholder, Parent or the Company for any obligations or liabilities of any party under this Agreement or for any Legal Proceeding (whether in tort, contract or otherwise) based on, in respect of or by reason of the transactions contemplated hereby or in respect of any written or oral representations made or alleged to be made in connection herewith.

23. Severability. In the event that any term, provision, covenant or restriction of this Agreement, or the application thereof, becomes or is declared by a court of competent jurisdiction or other Governmental Authority to be illegal, void or unenforceable, the remainder of this Agreement will continue in full force and effect and the application of such provision to other Persons or circumstances will be interpreted so as reasonably to effect the intent of the parties hereto. The parties hereto further agree to replace such void or unenforceable provision of this Agreement with a valid and enforceable provision that will achieve, to the extent possible, the economic, business and other purposes of such void or unenforceable provision.

24. Counterparts. This Agreement and any amendments hereto may be executed in one or more counterparts, all of which will be considered one and the same agreement and will become effective when one or more counterparts have been signed (including by electronic signature) by each of the parties hereto and delivered to the other parties hereto, it being understood that all parties hereto need not sign the same counterpart. Any such counterpart, to the extent delivered by .pdf, .tif, .gif, .jpg or similar attachment to electronic mail (any such delivery, an “Electronic Delivery”), will be treated in all manners and respects as an original executed counterpart and will be considered to have the same binding legal effect as if it were the original signed version thereof delivered in person. No party hereto may raise the use of an Electronic Delivery to deliver a signature, or the fact that any signature or agreement or instrument was transmitted or communicated through the use of an electronic delivery, as a defense to the formation of a contract, and each party hereto forever waives any such defense, except to the extent such defense relates to lack of authenticity.

25. Amendment; Waiver. Subject to applicable Law and subject to the other provisions of this Agreement, this Agreement may be amended by the parties hereto, and the terms and conditions hereof may be waived, only by an instrument in writing signed on behalf of each of the parties hereto, or, in the case of a waiver, by an instrument signed on behalf of the party waiving compliance. No failure or delay on the part of a party in the exercise of any right or remedy hereunder shall impair such right or power or be construed to be a waiver of, or acquiescence in, any breach of any representation, warranty or agreement herein, nor shall any single or partial exercise of any such right preclude any other or further exercise thereof or of any other right or power.

26. No Presumption Against Drafting Party. The Company, Parent and the Stockholder acknowledge that each party to this Agreement has been represented by counsel in connection with this Agreement and the transactions contemplated by this Agreement. Accordingly, any rule of law or any legal decision that would require interpretation of any claimed ambiguities in this Agreement against the drafting party has no application and is expressly waived.

27. Special Committee Approval. Notwithstanding any provision to the contrary, prior to the Effective Time, no amendment or waiver of any provision of this Agreement shall be made by the Company or the Company Board without first obtaining the approval of the Special Committee. Prior to the Effective Time, the Special Committee shall direct enforcement by the Company of any provisions of this Agreement against the Stockholder.

28. No Agreement until Executed. This Agreement shall not be effective unless and until (i) the Company Board and the Special Committee have approved, for purposes of any applicable anti-takeover laws and regulations, and any applicable provision of the DGCL, the Charter, the Bylaws or any similar organization document of the Company, the Merger Agreement, the Support Agreements and the transactions contemplated by the Merger Agreement, including the Transactions, (ii) the Merger Agreement is executed by all parties thereto and (iii) this Agreement is executed and delivered by all parties hereto.

29. No Ownership Interest. Except as expressly provided in Section 3 with respect to the Rollover Shares following the consummation of the Exchange at the Exchange Time and as expressly provided in Section 1 with respect to the tender of the Covered Shares, nothing contained in this Agreement shall be deemed to vest in Parent any direct or indirect ownership or incidence of ownership of or with respect to any Voting Shares. All ownership and economic benefits of and relating to the Voting Shares shall remain vested in and belong to the applicable Stockholder.

30. No Other Representations and Warranties. The Company, Parent and the Stockholder acknowledge and agree that, except for the representations and warranties expressly set forth in Section 7, Section 8 and Section 9 of this Agreement, none of the Company, Parent or the Stockholder makes, has made, or shall be deemed to have made, any representation or warranty in connection with this Agreement. The Company, Parent and the Stockholder acknowledge and agree that each is not entering into this Agreement in reliance on any representation or warranty, express or implied, except for the representations and warranties expressly set forth in Section 7, Section 8 or Section 9, as applicable.
