NOW, THEREFORE, the Parties, intending to be legally bound, hereby agree as follows:

SECTION 1. VOTING PROVISIONS

Section 1.1 Voting of Subject Securities. Each Party agrees that, at each annual, extraordinary or other general meeting of shareholders of FINV (or at any adjournment or postponement thereof or pursuant to any consent in lieu of a meeting or otherwise) at which members of the supervisory board or management board are to be elected, it will vote (or cause to be voted) all Subject Securities Beneficially Owned by it for the election of members of FINV’s supervisory board or management board in accordance with the instructions of the Shareholder Representative.

Section 1.2 Transfer of Voting Restrictions. The Parties agree that they will not Transfer any Subject Securities to any Affiliate unless and until such transferee has agreed in writing to be bound by this Agreement by execution of a Joinder Agreement (which such execution shall be deemed, for all purposes, to be the execution of this Agreement). Notwithstanding anything to the contrary in this Agreement other than Section 3.8, this Agreement does not restrict the ability of any Party to Transfer any Subject Securities to any non-Affiliate at any time or from time to time, and no such non-Affiliate transferee (and no Subject Securities Transferred to any non-Affiliate provided that following such Transfer no Party Beneficially Owns such Subject Securities) will be bound by this Agreement.

Section 1.3 Legends. The Parties agree that stop transfer instructions reflecting the terms of this Agreement will be given to FINV’s transfer agent with respect to the Subject Securities and that there may be placed on the certificates, if any, representing all Subject Securities an appropriate legend to ensure compliance with the terms of this Agreement. Any such instructions and legends will be removed with respect to any Subject Securities as soon as reasonably practicable after the later of (a) the time this Agreement no longer applies to such Subject Securities and (b) the date that the relevant Party requests such removal by notice pursuant to this Agreement.

SECTION 2. REPRESENTATIONS AND WARRANTIES

Section 2.1 Due Organization. Each Party that is not a natural person represents and warrants that it is an entity duly organized, validly existing and in good standing, as applicable, under the laws of its jurisdiction of formation and has the power and authority to enter into this Agreement and to carry out its obligations hereunder.

Section 2.2 Due Authorization. Each Party represents and warrants that the execution and delivery of this Agreement by such Party have been duly authorized by all necessary action on its part and no other proceedings on its part are necessary to authorize this Agreement or any of the transactions contemplated hereby.

Section 2.3 Due Execution. Each Party represents and warrants that this Agreement has been duly executed and delivered by such Party and constitutes a valid and binding obligation of each of them, and is enforceable against each of them in accordance with its terms.

SECTION 3. MISCELLANEOUS

Section 3.1 Effectiveness. To the extent the Offering is not consummated by January 1, 2014, the provisions of Section 1 of this Agreement shall be void and of no effect.

Section 3.2 Term. This Agreement shall terminate on the date following the Offering on which no Party Beneficially Owns any Subject Securities; provided that this Agreement shall automatically terminate if the Offering is not consummated by January 1, 2014.

2

Section 3.3 Notices. Any notice, communication, request, instruction or other document required or permitted hereunder shall be given in writing and delivered in person or sent by mail (postage prepaid, return receipt requested) or facsimile to the applicable addresses set forth on the signature page to this Agreement. Any such notice shall be effective upon receipt only if received during normal business hours or, if not received during normal business hours, on the next Business Day.

Each Party may, by written notice so delivered, change its address for notice purposes hereunder.

Section 3.4 Amendments; No Waivers.

(a) Any provision of this Agreement may be amended or waived if, and only if, such amendment or waiver is in writing and signed, in the case of an amendment, by all Parties, or in the case of a waiver, by the Party against whom the waiver is to be effective.

(b) No failure or delay by any Party hereto in the exercise of any right hereunder shall impair such right or be construed as 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 other or further exercise thereof or of any other right. All rights and remedies existing under this Agreement are cumulative to, and not exclusive of, any rights or remedies otherwise available.

Section 3.5 Successors. All covenants and other agreements contained in this Agreement by or on behalf of any of the Parties bind and inure to the benefit of their respective successors whether so expressed or not.

Section 3.6 Severability. Any provision of this Agreement that is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall (to the full extent permitted by law) not invalidate or render unenforceable such provision in any other jurisdiction.

Section 3.7 Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be an original but all of which together shall constitute one instrument. Each counterpart may consist of a number of copies hereof, each signed by less than all, but together signed by all, of the Parties hereto.

Section 3.8 Specific Performance. The Parties each acknowledge and agree, and agree not to assert otherwise in any proceeding, that a breach or threatened breach of any of the provisions of this Agreement by a Party will cause irreparable injury to the other Parties to this Agreement for which remedies at law would be inadequate and, in recognition of that fact, agree that, in the event of a breach or threatened breach by any of them of the provisions of this Agreement, in addition to any remedies at law, the aggrieved Party, without posting any bond and without any showing of irreparable injury, shall be entitled to obtain equitable relief in the form of specific performance, a temporary restraining order, a temporary or permanent injunction or any other equitable remedy which may then be available. The provisions of this Section 3.7 are without prejudice to any other rights that the Parties hereto may have for any breach of this Agreement. The Parties further agree not to assert in any proceeding that grounds for any equitable relief are not satisfied.

Section 3.9 Protections and Benefits of Agreement. None of the Parties shall take any knowing or intentional action to deprive the other Parties of the benefits and protections afforded by this Agreement, including without limitation selling any of the Subject Securities to a Person that is not an Affiliate of such Party with an agreement or understanding that such Subject Securities will be re-purchased by such Party or any of its Affiliates free and clear of any restrictions contained in this Agreement or with an agreement or understanding to vote such Subject Securities in a manner directed by such party.

Section 3.10 Governing Law. This Agreement shall be construed and enforced in accordance with, and the rights of the Parties shall be governed by, the laws of the State of Texas, without regard to the conflict of law principles thereof. Any suit, action or proceeding arising out of or relating to this Agreement may be brought in any state or federal court of competent jurisdiction in Harris County, Texas, and each of the Parties hereby consents to the jurisdiction of such courts (and of the appropriate appellate courts therefrom). Each Party waives any objection which it may have now or hereafter to the laying of the venue of such action or proceeding and irrevocably submits to the jurisdiction of any such court in any such suit, action or proceeding. The Parties unconditionally waive any right to trial by jury in any such suit, action or proceeding.

Section 3.11 Additional Shares. In the event (i) of any stock dividend, stock split, recapitalization, reclassification, combination or exchange of shares of capital stock of FINV on, of or affecting a Party’s Subject Shares or (ii) a Party becomes the beneficial owner of any additional shares of Common Stock, Preferred Stock or other securities of FINV entitling the holder thereof to vote or give consent with respect to the matters set forth in Section 1.1 hereof, then the terms of this Agreement shall apply to the shares of capital stock or other securities of FINV held by such Party immediately following the effectiveness of the events described in clause (i) or such Party becoming the beneficial owner thereof, as described in clause (ii). Each Party hereby agrees, while this Agreement is in effect, to notify FINV of the number of any new shares of Common Stock or Preferred Stock acquired by such party, if any, after the date hereof.
