**AGREEMENT **

1. Company Stockholder Consent and Related Matters.

(a) As promptly as reasonably practicable (and in any event within two (2) Business Days) following the time at which the Registration Statement / Proxy Statement is declared effective under the Securities Act, the Stockholder shall duly execute and deliver to the Company and TCGX (i) the Company Stockholder Written Consent, in the form attached hereto as Exhibit*** A*, under which it shall irrevocably and unconditionally consent to the matters, actions and proposals contemplated by Section 5.13(b) (Transaction Support Agreements; Company Stockholder Approval) of the Business Combination Agreement; and (ii) execute and deliver all additional agreements, documents and instruments and take, or cause to be taken, all actions necessary or reasonably advisable in order to amend or otherwise modify the Governing Documents of the Company, the Company Stockholder Agreements and each other applicable Contract in the manner required by Section 5.13(b) (Transaction Support Agreements; Company Stockholder Approval) of the Business Combination Agreement. Without limiting the generality of the first sentence of this Section*** 1(a)*, prior to the Closing, the Stockholder shall appear (in person or by proxy) at any meeting (whether annual or special and whether or not an adjourned or postponed meeting) of the stockholders of the Company, however called, or otherwise cause the Subject Company Shares to be counted as present thereat for purposes of establishing a quorum, and shall vote (or cause to be voted), at any such meeting, and in any action by written resolution of the stockholders of the Company, at which the Business Combination Agreement and other related agreements (or any amended version thereof) or such other related actions, are submitted for the consideration of the stockholders of the Company, the Subject Company Shares:

(i) in favor of: (A) the approval and adoption of the Business Combination Agreement; and (B) the Merger, the Company Preferred Share Conversion and the other transactions contemplated by the Business Combination Agreement, including the Ancillary Documents and all other agreements related to the Merger to which the Company or any other Group Company is a party or to which TCGX or Merger Sub is a party; provided that, for the avoidance of doubt, nothing in this Agreement shall require the Stockholder to vote or cause to be voted in any manner with respect to any amendment to the Business Combination Agreement in a manner that (x) decreases the Aggregate Transaction Share Consideration or the Stockholder’s Pro Rata Share thereof, (y) changes the form of the Aggregate Transaction Share Consideration or the Stockholder’s Pro Rata Share thereof, or (z) extends the Termination Date or imposes new obligations or liabilities on the Stockholder; provided, further, that the foregoing shall apply only to an amendment that the Stockholder has not consented to in writing; and

(ii) against and withhold consent, including by written consent or written resolution, with respect to (A) any Company Acquisition Proposal or (B) any other matter, action, transaction, agreement or proposal that is intended or that would reasonably be expected to (x) result in a breach of any of the Company’s covenants, agreements or obligations under the Business Combination Agreement, (y) result in a breach of any of the conditions to the Closing set forth in Sections 6.1 (Conditions to the Obligations of the Parties), or 6.2 (Other Conditions to the Obligations of the TCGX Parties) of the Business Combination Agreement not being satisfied, or (z) frustrate the purposes of, impede, hinder, interfere with, prevent or delay the consummation of, or otherwise adversely affect, the Merger, or any of the other transactions contemplated by the Business Combination Agreement or any of the other agreements related to the Merger (including the Ancillary Documents to which the Company or any other Group Company is a party or to which TCGX or Merger Sub is a party) including: (aa) any extraordinary corporate transaction, such as a merger, consolidation or other business combination involving any Group Company, TCGX or Merger Sub, in each case other than the Merger and the other transactions contemplated by the Business Combination Agreement; (bb) a reorganization, recapitalization or liquidation of any Group Company, TCGX or Merger Sub, in each case other than the Merger and the other transactions contemplated by the Business Combination Agreement; or (cc) any amendment or other change to the Governing Documents of any Group Company, TCGX or Merger Sub (other than as expressly contemplated in or permitted by the Business Combination Agreement or the Ancillary Documents), except if approved in writing by TCGX.

2

(b) The Stockholder shall not, and shall cause such Stockholder’s Affiliates not to, directly or indirectly, (1) initiate, seek, solicit, knowingly facilitate or knowingly encourage (including by way of furnishing any nonpublic information), whether publicly or otherwise, any inquiries with respect to, or the making or submission of, a Company Acquisition Proposal, (2) enter into or engage in any negotiations or discussions with, or provide any nonpublic information to, or afford access to the business, properties, assets, books or records of any Group Company, TCGX or Merger Sub to, any Person (other than TCGX or any of its Representatives) relating to or for the purpose of encouraging or facilitating any Company Acquisition Proposal (other than to state that the terms of this Agreement prohibit such discussions), (3) amend or grant any waiver or release under any standstill or similar agreement with respect to any class of equity interests of any Group Company, TCGX or Merger Sub, (4) approve, endorse, recommend, execute or enter into any agreement in principle, letter of intent, memorandum of understanding, term sheet, acquisition agreement, merger agreement, option agreement, joint venture agreement, partnership agreement or other Contract relating to any Company Acquisition Proposal, or any proposal or offer that could reasonably be expected to lead to a Company Acquisition Proposal, or (5) resolve or agree to do any of the foregoing or otherwise authorize or permit any of its Representatives to take any such action.

(c) For the avoidance of doubt, in the event that (i) any Subject Company Shares are issued to any Stockholder after the date of this Agreement pursuant to any share dividend, share split, recapitalization, reclassification, combination or exchange of Subject Company Shares of, on or affecting the Subject Company Shares owned by such Stockholder or otherwise, (ii) such Stockholder purchases or otherwise acquires beneficial ownership of any Subject Company Shares after the date of this Agreement, or (iii) such Stockholder acquires the right to vote or share in the voting of any Subject Company Shares after the date of this Agreement (such Subject Company Shares or other equity securities of the Company, collectively the “New Securities”), then such New Securities acquired or purchased by such Stockholder shall constitute Subject Company Shares and shall be subject to the terms of this Agreement (including with respect to the voting and proxy requirements set forth in this Section*** 1*) to the same extent as if they constituted Subject Company Shares owned by such Stockholder as of the date of this Agreement.

(d) Without limiting any other rights or remedies of TCGX, the Stockholder hereby irrevocably appoints TCGX or any individual designated by TCGX as the Stockholder’s agent, attorney-in-fact and proxy (with full power of substitution and resubstitution), for the purposes of complying with obligations hereunder in accordance with the laws of the State of Delaware and on such Stockholder’s behalf, for and in the name, place and stead of the Stockholder, to attend on behalf of the Stockholder any meeting of the Company Stockholders with respect to the matters described in Section*** 1(a), to include the Subject Company Shares in any computation for purposes of establishing a quorum at any such meeting of the Company Stockholders, to vote (or cause to be voted) the Subject Company Shares or consent (or withhold consent) with respect to any of the matters described in Section** 1(a)* in connection with any meeting of the Company Stockholders or any action by written consent by the Company Stockholders (including the Company Stockholder Written Consent), in each case, in the event that the Stockholder fails to provide its consent or vote its Subject Company Shares in accordance with Section*** 1(a)* or perform or otherwise comply with the covenants, agreements or obligations set forth in Section*** 1(a)*.

3

(e) The proxy granted by the Stockholder pursuant to Section*** 1(d)* is coupled with an interest sufficient in law to support an irrevocable proxy and is granted in consideration for TCGX entering into the Business Combination Agreement and agreeing to consummate the transactions contemplated thereby. The Stockholder authorizes such attorney-in-fact and proxy to substitute any other Person to act hereunder, to revoke any substitution and to file this proxy and any substitution or revocation with the Secretary of the Company. The proxy granted by the Stockholder pursuant to Section*** 1(d)* is also a durable proxy and shall survive the bankruptcy, dissolution, death, incapacity or other inability to act by the Stockholder and the Stockholder hereby revokes any and all prior proxies granted by the Stockholder with respect to the Subject Company Shares. The vote or consent of the proxyholder in accordance with Section*** 1(d)* and with respect to the matters in Section*** 1(a)* shall control in the event of any conflict between such vote or consent by the proxyholder of the Subject Company Shares and a vote or consent by the Stockholder of the Subject Company Shares (or any other Person with the power to vote the Subject Company Shares) with respect to the matters in Section*** 1(a). The proxyholder may not exercise the proxy granted pursuant to Section** 1(d)* on any matter except those provided in Section*** 1(a)*. For the avoidance of doubt, the Stockholder may vote the Subject Company Shares on all other matters, subject to, for the avoidance of doubt, the other applicable covenants, agreements and obligations set forth in this Agreement. The Stockholder hereby affirms that the irrevocable proxy is coupled with an interest and may under no circumstances be revoked and that such irrevocable proxy is executed and intended to be irrevocable. Notwithstanding any other provision of this Agreement, the irrevocable proxy granted hereunder shall automatically terminate upon the termination of this Agreement. The Stockholder agrees not to grant any proxy that conflicts or is inconsistent with the proxy granted to TCGX in this Agreement.

2. Other Covenants and Agreements.

(a) The Stockholder hereby agrees that, notwithstanding anything to the contrary in any such agreement, (i) without the prior written consent of TCGX (not to be unreasonably withheld, delayed or conditioned), such Stockholder shall not modify or amend any Contract between or among such Stockholder, anyone related by blood, marriage or adoption to such Stockholder or any Affiliate of such Stockholder (other than the Company or any other Group Company), in each case in his or her capacity as a stockholder of the Company, on the one hand, and the Company or any other Group Company, on the other hand, including, for the avoidance of doubt, each of the agreements set forth on Schedule*** B*, (ii) each of the agreements set forth on Schedule*** B* hereto shall be automatically terminated and of no further force and effect (including any provisions of any such agreement that, by its terms, survive such termination) effective as of, and subject to and conditioned upon the occurrence of, the Closing and (iii) upon such termination neither the Company nor any of its Affiliates (including the other Group Companies and, from and after the Effective Time, TCGX and its Affiliates) shall have any further obligations or liabilities under each such agreement; provided, however, that the indemnification provisions that are contemplated to survive the agreement marked with an asterisk (*) on Schedule*** B* shall survive such termination in accordance with their terms. Without limiting the generality of the foregoing, the Stockholder hereby agrees to promptly execute and deliver all additional agreements, documents and instruments and take, or cause to be taken, all actions necessary or reasonably advisable in order to achieve the purpose of the preceding sentence.

4

(b) The Stockholder shall be bound by and subject to (i) Sections 5.3(a) (Confidentiality and Access to Information) and 5.4(a) (Public Announcements) of the Business Combination Agreement to the same extent as such provisions apply to the parties to the Business Combination Agreement, as if the Stockholder is directly party thereto, and (ii) Sections 5.6(a) (Exclusive Dealing) and 8.18 (Trust Account Waiver) of the Business Combination Agreement to the same extent as such provisions apply to the Company, as if the Stockholder is directly party thereto.

(c) The Stockholder acknowledges and agrees that TCGX and the other TCGX Parties are entering into the Business Combination Agreement in reliance upon the Stockholder entering into this Agreement and agreeing to be bound by, and perform, or otherwise comply with, as applicable, the agreements, covenants and obligations contained in this Agreement and but for the Stockholder entering into this Agreement and agreeing to be bound by, and perform, or otherwise comply with, as applicable, the agreements, covenants and obligations contained in this Agreement, TCGX and the other TCGX Parties would not have entered into or agreed to consummate the transactions contemplated by the Business Combination Agreement.

3. Stockholder Representations and Warranties. The Stockholder represents and warrants to TCGX as follows:

(a) The Stockholder is a corporation, limited liability company or other applicable business entity duly organized or formed, as applicable, validly existing and in good standing (or the equivalent thereof, if applicable, in each case, with respect to the jurisdictions that recognize the concept of good standing or any equivalent thereof) under the Laws of its jurisdiction of formation or organization (as applicable) or, if the Stockholder is a natural person, the Stockholder has the legal capacity to execute and deliver this Agreement and to perform his or her covenants, agreements and obligations hereunder.

(b) The Stockholder has the requisite corporate, limited liability company or other similar power and authority to execute and deliver this Agreement, to perform its covenants, agreements and obligations hereunder (including, for the avoidance of doubt, those covenants, agreements and obligations hereunder that relate to the provisions of the Business Combination Agreement), and to consummate the transactions contemplated hereby. The execution and delivery of this Agreement has been duly authorized by all necessary corporate (or other similar) action on the part of the Stockholder. This Agreement has been duly and validly executed and delivered by the Stockholder and constitutes a valid, legal and binding agreement of the Stockholder (assuming that this Agreement is duly authorized, executed and delivered by TCGX), enforceable against the Stockholder in accordance with its terms (subject to applicable bankruptcy, insolvency, reorganization, moratorium or other Laws affecting generally the enforcement of creditors’ rights and subject to general principles of equity).

5

(c) No consent, approval or authorization of, or designation, declaration or filing with, any Governmental Entity is required on the part of the Stockholder with respect to the Stockholder’s execution, delivery or performance of its covenants, agreements or obligations under this Agreement (including, for the avoidance of doubt, those covenants, agreements and obligations under this Agreement that relate to the provisions of the Business Combination Agreement) or the consummation of the transactions contemplated hereby, except for any consents, approvals, authorizations, designations, declarations, waivers or filings, the absence of which would not adversely affect the ability of the Stockholder to perform, or otherwise comply with, any of its covenants, agreements or obligations hereunder in any material respect.

(d) None of the execution or delivery of this Agreement by the Stockholder, the performance by the Stockholder of any of its covenants, agreements or obligations under this Agreement (including, for the avoidance of doubt, those covenants, agreements and obligations under this Agreement that relate to the provisions of the Business Combination Agreement) or the consummation of the transactions contemplated hereby will, directly or indirectly (with or without due notice or lapse of time or both) (i) result in any breach of any provision of the Stockholder’s Governing Documents, (ii) result in a violation or breach of, or constitute a default or give rise to any right of termination, Consent, cancellation, amendment, modification, suspension, revocation or acceleration under, any of the terms, conditions or provisions of any Contract to which the Stockholder is a party, (iii) violate, or constitute a breach under, any Order or applicable Law to which the Stockholder or any of its properties or assets are bound or (iv) result in the creation of any Lien upon the Subject Company Shares, except, in the case of any of clauses (ii) and (iii) above, as would not adversely affect the ability of the Stockholder to perform, or otherwise comply with, any of its covenants, agreements or obligations hereunder in any material respect.

(e) The Stockholder is the record and beneficial owner of the Subject Company Shares and has valid, good and marketable title to the Subject Company Shares, free and clear of all Liens (other than transfer restrictions under applicable Securities Law or under the Company Stockholder Agreements). Except for the Equity Securities of the Company set forth on Schedule*** A* hereto, together with any other Equity Securities of the Company that the Stockholder acquires record or beneficial ownership of after the date hereof that is either permitted pursuant to, or acquired in accordance with, Section 5.1(b)(v) (Conduct of Business of the Company) of the Business Combination Agreement, the Stockholder does not own, beneficially or of record, any Equity Securities of any Group Company. Except as otherwise expressly contemplated by the agreements listed on Schedule*** B* and any related acknowledgement agreement existing on the date hereof and made available to TCGX or any agreement that is entered into in accordance with the Business Combination Agreement, the Stockholder does not have the right to acquire any Equity Securities of any Group Company. The Stockholder has the sole right to vote (and provide consent in respect of, as applicable) the Subject Company Shares and, except for this Agreement, the Business Combination Agreement and the Company Stockholder Agreements, the Stockholder is not party to or bound by (i) any option, warrant, purchase right, or other Contract that would (either alone or in connection with one or more events, developments or circumstances (including the satisfaction or waiver of any conditions precedent)) require the Stockholder to Transfer any of the Subject Company Shares or (ii) any voting trust, proxy or other Contract with respect to the voting or Transfer of any of the Subject Company Shares.

6

(f) There is no Proceeding pending or, to the Stockholder’s knowledge, threatened against the Stockholder that, if adversely decided or resolved, would reasonably be expected to adversely affect the ability of the Stockholder to perform, or otherwise comply with, any of its covenants, agreements or obligations under this Agreement in any material respect.

(g) The Stockholder, on his, her or its own behalf and on behalf of his, her or its Representatives, acknowledges, represents, warrants and agrees that (i) he, she or it has conducted his, her or its own independent review and analysis of, and, based thereon, has formed an independent judgment concerning, the business, assets, condition, operations and prospects of, the TCGX Parties and (ii) he, she or it has been furnished with or given access to such documents and information about the TCGX Parties and their respective businesses and operations as he, she or it and his, her or its Representatives have deemed necessary to enable him, her or it to make an informed decision with respect to the execution, delivery and performance of this Agreement, the other Ancillary Documents to which he, she or it is or will be a party and the transactions contemplated hereby and thereby.

(h) In entering into this Agreement and the other Ancillary Documents to which he, she or it is or will be a party, the Stockholder has relied solely on his, her or its own investigation and analysis and the representations and warranties expressly set forth in the Ancillary Documents to which he, she or it is or will be a party and no other representations or warranties of any TCGX Party (including, for the avoidance of doubt, none of the representations or warranties of any TCGX Party set forth in the Business Combination Agreement or any other Ancillary Document), any TCGX Non-Party Affiliate or any other Person, either express or implied, and the Stockholder, on his, her or its own behalf and on behalf of his, her or its Representatives, acknowledges, represents, warrants and agrees that, except for the representations and warranties expressly set forth in the Ancillary Documents to which he, she or it is or will be a party, none of the TCGX Parties, any TCGX Non-Party Affiliate or any other Person makes or has made any representation or warranty, either express or implied, in connection with or related to this Agreement, the Ancillary Documents to which he, she or it is or will be a party or the transactions contemplated hereby or thereby.

4. Transfer of Subject Securities. Except as expressly contemplated by the Business Combination Agreement or with the prior written consent of TCGX (such consent to be given or withheld in its sole discretion), from and after the date hereof, the Stockholder agrees not to (a) Transfer any of the Subject Company Shares, (b) enter into (i) any option, warrant, purchase right, or other Contract that would (either alone or in connection with one or more events, developments or circumstances (including the satisfaction or waiver of any conditions precedent)) require the Stockholder to Transfer the Subject Company Shares or (ii) any voting trust, proxy or other Contract with respect to the voting or Transfer of the Subject Company Shares, or (c) take any actions in furtherance of any of the matters described in the foregoing clauses (a) or (b). For purposes of this Agreement, “Transfer” means any direct or indirect sale, transfer, assignment, pledge, mortgage, exchange, hypothecation, grant of a security interest in or disposition or encumbrance of an interest (whether with or without consideration, whether voluntarily or involuntarily or by operation of law or otherwise); provided, however, that the foregoing restrictions shall not apply to any Transfer (a “Permitted Transfer”): (i) to any Affiliate of such Stockholder, including to any member, partner, stockholder, or other equity holder of such Holder, or to any family member or trust for the benefit of such Holder or such Holder’s family members, (ii) by will or intestate succession upon the death of such Holder, or (iii) pursuant to a court order or settlement agreement related to the distribution of assets in connection with the dissolution of marriage or civil union; provided, further, that any Permitted Transfer shall be permitted only if, as a precondition to such Transfer, the transferee agrees in a writing, reasonably satisfactory in form and substance to TCGX, to assume all of the obligations of such Stockholder under, and be bound by all of the terms of, this Agreement.

7

5. Termination. This Agreement shall automatically terminate, without any notice or other action by any Party, and be void ab initio upon the earlier of (a) the mutual written consent of the Stockholder and TCGX, (b) the Effective Time, and (c) the termination of the Business Combination Agreement in accordance with its terms. Upon termination of this Agreement as provided in the immediately preceding sentence, none of the Parties shall have any further obligations or Liabilities under, or with respect to, this Agreement. Notwithstanding the foregoing or anything to the contrary in this Agreement, (i) the termination of this Agreement shall not affect any Liability on the part of any Party for a Willful Breach of any covenant or agreement set forth in this Agreement prior to such termination or Fraud, (ii)* Section**** 2(b)(i)* (solely to the extent that it relates to Section 5.3(a) (Confidentiality and Access to Information) of the Business Combination Agreement) and the representations and warranties set forth in Sections*** 3(g)* and (h) shall each survive any termination of this Agreement, (iii)* Section**** 2(b)(i)* (solely to the extent that it relates to Section 5.4(a) (Public Announcements) of the Business Combination Agreement) shall survive the termination of this Agreement pursuant to Section*** 5(a)* and (iv)* Section**** 2(b)(ii)* (solely to the extent that it relates to Section 8.18 (Trust Account Waiver) of the Business Combination Agreement) shall survive any termination of this Agreement. For purposes of this Section*** 5*, (x) “Willful Breach” means a material breach that is a consequence of an act undertaken or a failure to act by the breaching Party with the knowledge that the taking of such act or such failure to act would, or would reasonably be expected to, constitute or result in a breach of this Agreement and (y) “Fraud” means an act or omission committed by a Party, and requires: (A) a false or incorrect representation or warranty expressly set forth in this Agreement, (B) with actual knowledge (as opposed to constructive, imputed or implied knowledge) by the Party making such representation or warranty that such representation or warranty expressly set forth in this Agreement is false or incorrect, (C) an intention to deceive another Party, to induce him, her or it to enter into this Agreement, (D) another Party, in justifiable or reasonable reliance upon such false or incorrect representation or warranty expressly set forth in this Agreement, causing such Party to enter into this Agreement, and (E) another Party to suffer damage by reason of such reliance. For the avoidance of doubt, “Fraud” does not include any claim for equitable fraud, promissory fraud, unfair dealings fraud or any torts (including a claim for fraud or alleged fraud) based on negligence or recklessness.

6. Fiduciary Duties. Notwithstanding anything in this Agreement to the contrary, (a) the Stockholder makes no agreement or understanding herein in any capacity other than in such Stockholder’s capacity as a record holder and beneficial owner of the Subject Company Shares and (b) nothing in this Agreement shall limit or affect any actions or omissions taken by any representative of such Stockholder serving as a member of the board of directors of any Group Company or as an officer, employee or fiduciary of any Group Company, in each case, acting solely in such person’s capacity as a director, officer, employee or fiduciary of such Group Company.

7. No Recourse. Except for claims pursuant to the Business Combination Agreement or any other Ancillary Document by any party(ies) thereto against any other party(ies) thereto, each Party agrees that (a) this Agreement may only be enforced against, and any action for breach of this Agreement may only be made against, the Parties, and no claims of any nature whatsoever (whether in tort, contract or otherwise) arising under or relating to this Agreement, the negotiation

8

hereof or its subject matter, or the transactions contemplated hereby shall be asserted against the Company or any Company Non-Party Affiliate (other than the Stockholder named as a party hereto, on the terms and subject to the conditions set forth herein) or any TCGX Non-Party Affiliate, and (b) none of the Company, any Company Non-Party Affiliates (other than the Stockholder named as a party hereto, on the terms and subject to the conditions set forth herein) or any TCGX Non-Party Affiliate shall have any Liability arising out of or relating to this Agreement, the negotiation hereof or its subject matter, or the transactions contemplated hereby, including with respect to any claim (whether in tort, contract or otherwise) for breach of this Agreement or in respect of any written or oral representations made or alleged to be made in connection herewith, as expressly provided herein, or for any actual or alleged inaccuracies, misstatements or omissions with respect to any information or materials of any kind furnished in connection with this Agreement, the negotiation hereof or the transactions contemplated hereby.

9. Entire Agreement. This Agreement, the Business Combination Agreement and documents referred to herein and therein constitute the entire agreement of the Parties with respect to the subject matter of this Agreement, and supersede all prior agreements and undertakings, both written and oral, among the Parties with respect to the subject matter of this Agreement, except as otherwise expressly provided in this Agreement.

10. Amendments and Waivers; Assignment. Any provision of this Agreement may be amended or waived if, and only if, such amendment or waiver is in writing and signed by the Stockholder and TCGX. Notwithstanding the foregoing, no failure or delay by any Party in exercising any right hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise of any other right hereunder.

12. Remedies.

The Parties agree that irreparable damage for which monetary damages, even if available, would not be an adequate remedy, would occur in the event that either Party does not perform its respective obligations under the provisions of this Agreement in accordance with their specific terms or otherwise breaches such provisions. It is accordingly agreed that each Party shall be entitled to an injunction or injunctions, specific performance and other equitable relief to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement, in each case, without posting a bond or undertaking and without proof of damages and this being in addition to any other remedy to which they are entitled at law or in equity. Each Party agrees that it will not oppose the granting of an injunction, specific performance and other equitable relief when expressly available pursuant to the terms of this Agreement on the basis that the other Party has an adequate remedy at law or an award of specific performance is not an appropriate remedy for any reason at law or equity.

10

13. No Third Party Beneficiaries. This Agreement shall be for the sole benefit of the Parties and their respective successors and permitted assigns and is not intended, nor shall be construed, to give any Person, other than the Parties and their respective successors and permitted assigns, any legal or equitable right, benefit or remedy of any nature whatsoever by reason of this Agreement. Nothing in this Agreement, expressed or implied, is intended to or shall constitute the Parties partners or participants in a joint venture.

14. No Partnership, Agency or Joint Venture. This Agreement is intended to create a contractual relationship between the Stockholder and TCGX, and is not intended to create, and does not create, any agency, partnership, joint venture or any like relationship among any other Stockholders entering into voting agreements with the Company or TCGX. The Stockholder represents that it is not affiliated with any other holder of Subject Company Shares entering into a voting or support agreement with the Company or TCGX in connection with the Business Combination Agreement and acknowledges that it has acted independently regarding its decision to enter into this Agreement. Nothing contained in this Agreement shall be deemed to vest in TCGX any direct or indirect ownership or incidence of ownership of or with respect to any Subject Company Shares.
