SECTION 2.01 Board of Directors.

(b) Upon the closing of the Merger, the Board shall consist of four directors designated and nominated by ▇▇▇▇▇▇▇▇ and three directors designated and nominated by ▇▇▇▇, and ▇▇▇▇ and ▇▇▇▇▇▇▇▇ shall each designate half of the Independent Directors that are required for compliance under applicable laws and rules and regulations of the Approved Stock Exchange on which the Company’s shares will be listed; provided, that if an odd number of Independent Directors is required for compliance under applicable laws and rules and regulations of the Approved Stock Exchange on which the Company’s shares will be listed then one Independent Director shall be added to the required number of total Independent Directors for purposes of calculating the number to be appointed by each of the Shareholders. The directors designated and nominated by each of ▇▇▇▇▇▇▇▇ and ▇▇▇▇ will be distributed as evenly as possible among any classes of directors established pursuant to the Articles of Incorporation.

(c) In connection with any annual or special meeting of shareholders of the Company at which Directors are to be elected, unless both Shareholders otherwise agree, (i) until the Expiration Date with respect to ▇▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇ shall have the right to designate and nominate a majority of the nominees for appointment or election to the Board, at least a majority of whom shall be Non-U.S. Persons to the extent determined necessary by the Board in order to preserve the Company’s status as a Foreign Private Issuer, and (ii)

Notwithstanding the foregoing, the Nominating Committee may reject any proposed Director Nominee if it determines that such Director Nominee would not be qualified under any applicable law, rule or regulation to serve as a director or that the election or appointment of such Director Nominee would result in the loss of the Company’s status as a Foreign Private Issuer (which determination must set forth reasonable grounds for such determination and shall be notified to the relevant Shareholder in accordance with Section 6.01 below and by email), and in such event the relevant Shareholder may propose alternative Director Nominee(s) in furtherance of its Director Nomination Right.

(e) In the event that, any time following consummation of the Merger, the size of the Board is increased, in each case in accordance with the Articles of Incorporation and Bylaws and this Agreement, then the Board (or any committee thereof) shall, subject to this Section 2.01, have the right to nominate for election the remaining Directors (after any nominations made in accordance with this Section 2.01), in accordance with the Articles of Incorporation and Bylaws.

(f) The Shareholders shall notify the Company of any Director Nominee designated or recommended for appointment or election to the Board (including any Director Nominee so designated or recommended pursuant to the Director Nomination Right) in writing no later than 60 days prior to the first anniversary of the immediately preceding annual meeting of shareholders of the Company, or as otherwise approved by the Company in writing, together with all information concerning such Director Nominee required to be delivered to the Company by the Articles of Incorporation and Bylaws and such other information reasonably requested by the Company; provided, that if a Shareholder fails to give such notice in a timely manner, then such Shareholder shall be deemed to have nominated the incumbent Shareholder-Designated Director or Shareholder-Designated Directors, as applicable, in a timely manner. The Board shall, in its sole discretion and in accordance with the Articles of Incorporation and Bylaws, determine the classification assignment of any such Shareholder-Designated Director so appointed or elected.

(g) Until the Expiration Date with respect to a particular Shareholder, upon the death, resignation, retirement, disqualification or removal from office of any Shareholder-Designated Director, the Shareholder that nominated such Shareholder-Designated Director shall have the right to designate and nominate any replacement for such Shareholder-Designated Director, subject to, and in accordance with, the Governance Rights.

(h) In the event that the Board (or a committee thereof) relies on Section 2.05 to exclude a Director Nominee selected by the Shareholders pursuant to the Director Nomination Right from management’s slate of nominees (or otherwise take adverse action with respect to any such Director Nominee), the Company shall afford the Shareholders a reasonable opportunity to select a replacement Director Nominee.

(i) Without limiting the generality of Section 2.01(c), if the number of Shareholder-Designated Directors is less than the number that a Shareholder has the right to nominate pursuant to this Section 2.01, at the request of such Shareholder, the Secretary of the Company shall call a special meeting of the shareholders of the Company for the purpose of (i) removing Directors to create such vacancies as are necessary to permit such Shareholder to nominate and have elected the full number of Shareholder-Designated Directors that it is entitled (and wishes) to designate and nominate pursuant to this Section 2.01 or (ii) filling a vacancy on the Board. Upon the creation of any vacancy pursuant to the preceding sentence, such Shareholder shall designate and nominate the Person to fill such vacancy in accordance with this Section 2.01. Any Shareholder may call or demand that the Secretary of the Company call, a special meeting of the shareholders of the Company for the purpose of removing (with or without cause) any one or more Shareholder-Designated Directors that were nominated by such Shareholder.

(j) Each Shareholder-Designated Director shall be entitled to compensation and expense reimbursement in accordance with the Company’s policies and practices applicable to all Directors generally. The Company will also provide and hereby agrees to enter into indemnification agreements with the Shareholder-Designated Directors on terms not less favorable to the Shareholder-Designated Directors than any indemnification agreement entered into with any other Director.

As promptly as practicable following the nomination of the Shareholder-Designated Directors in accordance with Section 2.01(b) above, each Shareholder shall, and shall cause its Affiliates to, provide the other Shareholder a proxy for purposes of effecting clauses (i) and (ii) of the first sentence of this Section 2.02. In any matter submitted to a vote of shareholders not subject to this Section 2.02, a Shareholder may attend (or not attend or establish quorum) and vote (or not vote, or abstain) any or all of its Voting Stock in its sole discretion, subject to applicable Law.

In the event that a director or officer of the Company who is also a director, officer or employee of any Shareholder or its Affiliates acquires knowledge of a potential transaction or matter that may be an opportunity for the Company or any Affiliate thereof or any Shareholder or its Affiliates, such director or officer shall, to the fullest extent permitted by Law have fully satisfied and fulfilled his or her duty with respect to such opportunity, and the Company to the fullest extent permitted by Law acknowledges that it does not have any claim that such opportunity constituted an opportunity that should have been presented to the Company or any Affiliate thereof, if such director or officer acts in a manner consistent with the following policy: such an opportunity offered to any person who is an officer or director of the Company, and who is also an officer, director or employee of any Shareholder or its Affiliates, shall belong to such Shareholder or its Affiliates, unless such opportunity was offered to such person in his or her capacity as a director, officer or employee of the Company.

(e) This Section 2.03 is also intended to apply to any subsidiaries of the Company. In addition, references to a director or officer of a Shareholder in this Section 2.03 shall include any Person performing a similar function. The Company represents, warrants and agrees that it and its subsidiaries and their respective boards of directors (or equivalent) have not adopted and will not adopt any codes of conduct or ethics or other policies inconsistent with this Section 2.03.

SECTION 2.04 Articles of Incorporation and Bylaws. The Board and the Company shall take or cause to be taken all lawful action necessary to ensure at all times that the Articles of Incorporation and Bylaws are not at any time inconsistent in any material respect with the provisions of this Agreement. If and to the extent any provision in this Agreement is held unenforceable or void or in violation of public policy, the Company shall take best efforts to replicate such provisions in its Articles of Incorporation and Bylaws to make such provision valid and enforceable, including by way of issuing a preferred share containing the rights contained herein.

SECTION 2.05 Fiduciary Duties.

(a) Nothing in Article II shall be deemed to require the Board or any committee or member thereof to take any action or refrain from taking any action, or result in a breach of Article II by reason of such action or failure to act, if the Board, such committee or Director determines in good faith (after consideration of advice to such effect of outside legal counsel) that taking such action or refraining from taking such action, as the case may be, would cause a violation of his or her fiduciary duties to other shareholders of the Company, including the Shareholder Parties, under applicable Law.

(b) The Board shall owe the same fiduciary duties to each Shareholder, to the extent such Shareholder is a holder of Common Shares, as it owes to the other holders of Common Shares.

SECTION 2.06 Change in Law. In the event any Law comes into force or effect (including by amendment) which conflicts with the terms and conditions of this Agreement, the parties shall negotiate in good faith to revise this Agreement to achieve the parties’ intention set forth herein to the greatest extent possible.

SECTION 2.07 No Side Agreements. None of the Company and the Shareholders, including their Affiliates, shall enter, directly or indirectly, into any agreement or grant any proxy or power of attorney or become party to any voting trust or other agreement, relating to the Equity Securities of the Company or its subsidiaries or to the governance of the Company or any of its subsidiaries, which is inconsistent with or conflicts with the provisions of this Agreement.

SECTION 2.08 Affiliate Transactions. For so long as a Shareholder has a right to nominate any directors pursuant to this Agreement, all transactions involving such Shareholder or its Affiliates, on the one hand, and the Company or its subsidiaries, on the other hand, shall require the approval of a majority of the Independent Directors that are disinterested (or approved by a committee of the Board that is formed for this purpose and comprised solely of Independent Directors) and if such directors are two or fewer, the approval shall be unanimous; provided, that such approval by the Independent Directors that are disinterested shall not be required for (a) pro rata participation in primary offerings of Equity Securities of the Company based on number of outstanding Voting Stock held, (b) any amendments to or waivers of this Agreement, or (c) any other transactions expressly required or expressly permitted under this Agreement, the Merger or the other documents entered into in connection herewith and therewith without reference to such approval. A waiver of this Section 2.08 may be provided by all of the Shareholders (and not the Company).

SECTION 2.09 Subsequent Acquisitions. Each of the Shareholders and their Affiliates agrees that any other Equity Securities of the Company which it hereafter acquires, including by means of a share split, share dividend, distribution, conversion, exercise of options or warrants, or otherwise, shall be subject to the provisions of this Agreement to the same extent as if held on the date hereof.

SECTION 5.01 Notifications. Each Shareholder hereby undertakes to inform the other Shareholder by notice in writing as soon as it becomes aware of the occurrence or likely occurrence of an Insolvency Event affecting it or any of its Shareholder Parties except that in case the Shareholder is a publicly traded company, such disclosure shall not be required until so required by any applicable securities Laws or other securities exchange rules. A public filing with the SEC or an announcement of an Insolvency Event or a filing with a bankruptcy or insolvency court shall be deemed notice.

SECTION 5.02 Legend. (a) The Company may place appropriate legends and/or stop transfer orders on the shares of the Company held by the Shareholders setting forth the restrictions appropriate for compliance with U.S. federal securities laws, if applicable. The Shareholders agree with the Company that the shares of the Company held by the Shareholders may be marked with a legend substantially in the form set forth below, as well as any additional legend or restricted notation imposed or required by applicable securities Laws:

THESE SECURITIES AND THE SECURITIES ISSUABLE UPON THE EXCHANGE THEREOF HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”) OR THE SECURITIES LAWS OF ANY STATE OR OTHER JURISDICTION. THE SECURITIES MAY NOT BE OFFERED, SOLD, PLEDGED, TRANSFERRED OR OTHERWISE DISPOSED OF EXCEPT (1)

PURSUANT TO AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT (WHICH TRANSACTION SHALL BE ACCOMPANIED BY, IF REASONABLY REQUESTED BY THE COMPANY, AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE COMPANY THAT SUCH TRANSACTION DOES NOT REQUIRE REGISTRATION UNDER THE SECURITIES ACT AND OTHER APPLICABLE LAWS) OR (2) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT RELATING TO SUCH SECURITIES UNDER THE SECURITIES ACT, IN EACH CASE IN ACCORDANCE WITH ALL APPLICABLE STATE SECURITIES LAWS AND THE SECURITIES LAWS OF OTHER JURISDICTIONS.

THESE SECURITIES ARE SUBJECT TO RESTRICTIONS SET FORTH IN THE SHAREHOLDERS AGREEMENT DATED [•], 2025 AND EACH OF THE SHAREHOLDERS LISTED ON SCHEDULE A THERETO, AS AMENDED FROM TIME TO TIME.

(b) The parties hereto agree that, unless the relevant transfer agent of the Company requests an opinion of counsel for a transfer of shares of the Company, it shall not be reasonable for the Company to request an opinion relating to the transfer of shares pursuant to Rule 144 or an effective registration statement.

(c) The Company will promptly cause the transfer agent to remove the restrictive legend with respect to applicable shares of the Company, upon request, in order to permit the Shareholders to engage in sales, Transfers and other dispositions that are not restricted hereunder or under U.S. federal securities Laws, or are transferred in compliance with applicable U.S. federal securities Laws (and are no longer restricted securities or subject to this Agreement), or if the shares of the Company are no longer restricted under U.S. federal securities Laws (and are no longer restricted securities or subject to this Agreement).

(d) Purported transfers of shares of Equity Securities that are not in compliance with this Article V shall be void.

SECTION 5.03 Tag-Along Rights.

(a) Participation. At any time that any Shareholder or its Affiliate (the “Selling Shareholder”) proposes to sell or otherwise Transfer (a “Proposed Transferee”) a number of its Common Shares that equals or exceeds 3% of the outstanding Common Shares of the Company (whether in one Transfer or a series of related Transfers) to an Unaffiliated Third Party, each other Shareholder that, together with such other Shareholder’s Affiliates, owns more than 10% of the outstanding Common Shares of the Company (each, a “Tag-Along Shareholder”) shall be permitted to participate in such sale or Transfer (a “Tag-Along Sale”) on the terms and conditions set forth in this Section 5.03; provided, that this Section 5.03 shall not apply if the proposed Transfer is any one or more of (i) a Transfer from a Shareholder to one or more Affiliates of such Shareholder, (ii) a Transfer to an anonymous purchaser(s) through an Approved Stock Exchange or (iii) a Transfer to Underwriter(s) in an Underwritten Offering, as defined in and subject to the provisions of the Registration Rights Agreement entered into by the parties hereto on or about the date hereof (or any amendment thereto).

(b) Sale Notice. Prior to the consummation of any Tag-Along Sale, the Selling Shareholder shall deliver to the Company and each other Shareholder a written notice (a “Sale Notice”) of such Tag-Along Sale, together with fully-executed copies of any sale, merger, acquisition, or comparable transaction agreement pursuant to which such Tag-Along Sale is proposed to take place and all material ancillary agreements related thereto, no later than 10 Business Days after the execution and delivery by all the parties thereto of the definitive agreement entered into with respect to such Tag-Along Sale and, in any event, no later than 20 Business Days prior to the closing of such Tag-Along Sale. The Sale Notice shall make reference to the Tag-Along Shareholders’ rights and obligations hereunder and shall describe in reasonable detail:

(i) the number of Common Shares that the Selling Shareholder proposes to Transfer in such Tag-Along Sale, and the total number of outstanding Common Shares then held by the Selling Shareholder;

(ii) the identity of the Proposed Transferee;

(iii) the per share amount and form of consideration proposed to be paid or delivered to the Selling Shareholder in such Tag-Along Sale, including (x) any elections to be given to the Selling Shareholder with respect to such consideration, and (y) a description of any non-cash consideration in sufficient detail to permit the valuation thereof;

(iv) the terms of the Proposed Transferee’s financing;

(v) any other proposed material terms and conditions of such Tag-Along Sale; and

(vi) the proposed date, time, and location of the closing of such Tag-Along Sale.

(i) Each Tag-Along Shareholder that desires to participate in the Tag-Along Sale (a “Participating Tag-Along Shareholder”) shall exercise its rights under this Section 5.03 by delivering to the Selling Shareholder a written notice (a “Tag-Along Notice”), within 10 Business Days after its receipt of the Sale Notice (the “Tag-Along Period”), stating (A) its election to participate in the Tag-Along Sale on the terms and conditions set forth in the Sale Notice and in accordance with this Section 5.03 and (B) the number of Common Shares it is offering to Transfer in such Tag-Along Sale. The offer of each Participating Tag-Along Shareholder set forth in its Tag-Along Notice shall be irrevocable and, to the extent such offer is accepted, shall be binding on such Participating Tag-Along Shareholder. Subject to Section 5.03(c)(ii), each Participating Tag-Along Shareholder shall have the right to Transfer in the Tag-Along Sale up to that number of Common Shares equal to the product of (1) the number of outstanding Common Shares then held by such Participating Tag-Along Shareholder, multiplied by (2) a fraction (x) the numerator of which is equal to the number of Common Shares the Selling Shareholder proposes to Transfer in such Tag-Along Sale and (y) the denominator of which is equal to the number of outstanding Common Shares then owned by the Selling Shareholder.

(ii) The Selling Shareholder shall use commercially reasonable efforts to include in the Tag-Along Sale all of the Common Shares that the Participating Tag-Along Shareholders have offered to Transfer pursuant to their Tag-Along Notices, it being understood that the Proposed Transferee shall not be required to purchase any Common Shares in excess of the number of shares set forth in the Sale Notice. In the event the Proposed Transferee elects to purchase less than all of the Common Shares sought to be sold by the Shareholders in the Tag-Along Sale, the number of shares to be sold to the Proposed Transferee by the Selling Shareholder and the Participating Tag-Along Shareholders shall be reduced pro rata in proportion to the number of Common Shares that each such Shareholder proposed to Transfer in such Tag-Along Sale so that the aggregate number of Common Shares to be sold by the Selling Shareholder and the Participating Tag-Along Shareholders collectively equals the aggregate number of Common Shares that the Proposed Transferee is willing to purchase (which in no event may be less than the number of Common Shares set forth in the Sale Notice, unless otherwise agreed by all Shareholders).

(iii) Each Tag-Along Shareholder that does not deliver a Tag-Along Notice in compliance with Section 5.03(c)(i) shall be deemed to have waived all of such Tag-Along Shareholder’s rights to participate in the Tag-Along Sale, and the Selling Shareholder shall (subject to the rights of any Participating Tag-Along Shareholders) thereafter be free to Transfer to the Proposed Transferee, without any further obligation to the Tag-Along Shareholders who are not Participating Tag-Along Shareholders under this Section 5.03, the number of Common Shares set forth in the Sale Notice for the same or lesser consideration per share, and on terms and conditions which are not materially more favorable to the Selling Shareholder, than the terms and conditions set forth in the Sale Notice without any further obligation to the non-accepting Tag-Along Shareholders.

(d) Consideration. The Selling Shareholder and each Participating Tag-Along Shareholder shall receive the same form and amount of consideration per share (or election regarding the form and amount of consideration) in the Tag-Along Sale; provided, that each such Shareholder’s proportionate share of related expenses will be deducted from such consideration in accordance with Section 5.03(f) below.

(e) Conditions of Sale. Each Participating Tag-Along Shareholder shall make or provide the same representations, warranties, covenants, and indemnities as the Selling Shareholder makes or provides in connection with the Tag-Along Sale (except that in the case of representations, warranties, covenants, and indemnities pertaining specifically to the Selling Shareholder, each Participating Tag-Along Shareholder shall make comparable representations, warranties, covenants, and indemnities pertaining specifically to itself); provided, that all representations, warranties, covenants, and indemnities shall be made by the Selling Shareholder and each Participating Tag-Along Shareholder severally and not jointly, and any indemnification obligations shall be limited to the aggregate amount of proceeds received by such Participating Tag-Along Shareholder in the Tag-Along Sale; and provided, further, that no Participating Tag-Along Shareholder shall be required to agree to any non-competition, non-solicitation, or similar restrictive covenant.

(f) Expenses. The fees and expenses of the Selling Shareholder incurred in connection with the Tag-Along Sale for the benefit of all Participating Tag-Along Shareholders (it being understood that costs incurred by or on behalf of the Selling Shareholder for its sole benefit will not be considered to be for the benefit of all Participating Tag-Along Shareholders), to the extent not paid or reimbursed by the Company or the Proposed Transferee, shall be shared by the Selling Shareholder and each Participating Tag-Along Shareholder on a pro rata basis, based on the amount of consideration received by each such Shareholder in the Tag-Along Sale; provided, that no Participating Tag-Along Shareholder shall be obligated to make any out-of-pocket expenditure prior to the consummation of the Tag-Along Sale.

(g) Cooperation. Each Participating Tag-Along Shareholder shall take all actions as may be reasonably necessary to consummate the Tag-Along Sale, including entering into agreements and delivering certificates and instruments, in each case consistent with the agreements being entered into and the certificates being delivered by the Selling Shareholder, subject to the limitations set forth in Section 5.03(e).

(h) Consummation of the Sale. The Selling Shareholder shall have 90 Business Days following the expiration of the Tag-Along Period to Transfer the Common Shares described in the Sale Notice, on terms not materially more favorable to the Selling Shareholder than those set forth in the Sale Notice and subject to the rights of the Tag-Along Shareholders set forth in this Section 5.03 (which 90-Business Day period may be extended by up to 120 Business Days to the extent reasonably necessary to obtain any required Government Approvals). If at the end of such period the Selling Shareholder has not completed the Tag-Along Sale, the Selling Shareholder may not then effect a sale of Common Shares subject to this Section 5.03 without again fully complying with the provisions of this Section 5.03.

(i) Sales in Violation of Tag-Along Rights. If the Selling Shareholder consummates any sale of Common Shares subject to this Section 5.03 in violation of this Section 5.03, then each Tag-Along Shareholder shall have the right to Transfer to the Selling Shareholder, and the Selling Shareholder shall be obligated to purchase from each Tag-Along Shareholder that exercises such right, up to that number of Common Shares that such Tag-Along Shareholder would have had the right to Transfer to the Proposed Transferee in such Tag-Along Sale if conducted in accordance with this Section 5.03, and on the same terms and conditions (including the same amount and form of consideration per share) under which the Proposed Transferee purchased the Common Shares from the Selling Shareholder, except that no Tag-Along Shareholder shall be required to indemnify the Selling Shareholder in connection with any Tag-Along Sale consummated pursuant to this Section 5.03(i), except for breach of representations or warranties regarding due authorization, ownership of the Common Shares, no liens, and enforceability. The Selling Shareholder shall reimburse each Tag-Along Shareholder for any and all reasonable and documented out-of-pocket fees and expenses, including reasonable legal fees and expenses, incurred pursuant to the exercise or the attempted exercise of the Tag-Along Shareholder’s rights under this Section 5.03(i).

The rights and remedies herein provided shall be cumulative and not exclusive of any rights or remedies provided by Law or otherwise.

SECTION 6.05 Further Assurances. Each party hereto shall do and perform or cause to be done and performed all further acts and shall execute and deliver all other agreements, certificates, instruments and documents as any other party hereto reasonably may request in order to carry out the intent and accomplish the purposes of this Agreement and the consummation of the transactions contemplated hereby.

SECTION 6.06 Assignment. Neither this Agreement nor any of the rights, interests or obligations under this Agreement shall be assigned, in whole or in part, by operation of Law or otherwise, by any of the parties without the prior written consent of the other parties hereto. Any purported assignment without such prior written consent shall be void.

SECTION 6.07 Governing Law. This Agreement and any claim, counterclaim or dispute of any kind or nature whatsoever arising out of or in any way relating to this Agreement, directly or indirectly, shall be governed by and construed in accordance with the laws of New York, regardless of the laws that might otherwise govern under applicable principles of conflicts of laws thereof. The parties declare that it is their intention that this Agreement shall be regarded as made under the laws of New York and that the laws of New York shall be applied in interpreting its provisions in all cases where legal interpretation shall be required except to the extent the ▇▇▇▇▇▇▇▇ Islands Business Corporations Act is specifically required by such act to govern the interpretation of this Agreement.

SECTION 6.09 Consent to Jurisdiction; Enforcement. The parties agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that the parties shall be entitled to an injunction or injunctions (without the proof of actual damages) to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement and that no party nor any of their respective Representatives shall oppose the granting of such relief, this being in addition to any other remedy to which they are entitled at law or in equity. Each party also agrees that it and its Representatives shall waive any requirement for the security or posting of any bond in connection with any such equitable relief. In addition, each of the parties irrevocably submits to the jurisdiction of the Federal and State courts of New York, which jurisdiction shall be exclusive, for the purposes of any suit, action or other proceeding arising out of this Agreement. Each party irrevocably and

unconditionally waives (and agrees not to plead or claim) any objection to the laying of venue of any action, suit or proceeding arising out of this Agreement in any court of New York or that any such action, suit or proceeding brought in any such court has been brought in an inconvenient forum. Each of the parties hereto agrees that a final judgment in any such action or proceeding will be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by ▇▇▇.

SECTION 6.10 Effectiveness. This Agreement shall become effective upon the closing of the Merger (the “Effective Date”).

SECTION 6.11 Confidentiality.

(a) The Shareholders agree to maintain, and shall cause their respective subsidiaries and Affiliates, and its and their directors, officers, partners, employees, agents, counsel, advisors, consultants and other Representatives (including any Shareholder-Designated Director appointed pursuant to Section 2.01(a)) to maintain, the confidentiality of all information obtained by the Shareholders and their Representatives from the Company or any of its subsidiaries or Representatives, and not to use such information for any purpose other than (i) the evaluation and protection of the investment by the Shareholders in the Company, (ii) the exercise by the Shareholder of any of its rights under this Agreement (including the right to acquire more Voting Stock or Transfer securities of the Company) and (iii) the exercise by the Shareholder-Designated Directors of their fiduciary duties as Directors of the Company.

(b) Notwithstanding anything to the contrary in the foregoing, the confidentiality obligations of Section 6.11(a) will not apply to information obtained other than in violation of this Agreement that:

(i) a Shareholder or any of its Affiliates is required to disclose by judicial or administrative process, or by other requirements of applicable Law or regulation or any governmental authority (including any applicable rule, regulation or order of a self-governing authority, such as an Approved Stock Exchange); provided, that where and to the extent practicable, the disclosing party (A) gives the other party reasonable notice of any such requirement and, to the extent protective measures consistent with such requirement are available, the opportunity to seek appropriate protective measures and (B) cooperates with such party in attempting to obtain such protective measures;

(ii) was or becomes generally available to the public other than as a result of a breach of Section 6.11(a); or

(iii) was or becomes available to the Shareholders or their subsidiaries or Representatives on a non-confidential basis by a third-party source who obtained such information other than from any such Person; provided, that such source is reasonably believed by each such Person not to be subject to an obligation of confidentiality (whether by agreement or otherwise) to the Company or any of its subsidiaries.

SECTION 6.12 Entire Agreement; No Third-Party Beneficiaries. This Agreement, together with any other agreement expressly contemplated herein or therein, constitutes the entire agreement between the parties with respect to the subject matter of this Agreement, and supersedes all prior agreements and understandings, both written and oral, between the parties or their Affiliates with respect to the subject matter hereof. No provision of this Agreement shall confer upon any Person other than the parties hereto any rights or remedies hereunder.

SECTION 6.13 Severability. If one or more provisions of this Agreement are held to be unenforceable under applicable Law, such provision shall be deemed to be excluded from this Agreement and the balance of this Agreement shall be interpreted as if such provision were so excluded and shall be enforced in accordance with its terms to the maximum extent permitted by Law, so long as the economic or legal substance of the transactions contemplated hereby 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 shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in an acceptable manner to the end that the transactions contemplated hereby are fulfilled to the extent possible.

SECTION 6.14 Counterparts. This Agreement may be executed in one or more counterparts, all of which shall be considered one and the same agreement and shall become effective when one or more such counterparts have been signed by each of the parties and delivered to the other parties, with the same effect as if the signatures were upon the same instrument. This Agreement may be signed electronically or by PDF.

SECTION 6.15 Acknowledgment of Securities Laws. Each Shareholder hereby acknowledges that it is aware, and that it will advise its Affiliates and representatives who are provided the material non-public information that is the subject of Section 6.11, that the United States securities laws prohibit any Person who has received from an issuer material, non-public information from purchasing or selling securities of such issuer or from communication of such information to any other Person under circumstances in which it is reasonably foreseeable that such Person is likely to purchase or Transfer such securities.

SECTION 6.16 Termination of Original Agreement. Effective as of the Effective Date, the Shareholders agree that the Original Shareholders Agreement is terminated and rendered null and void by this Agreement.

SECTION 6.17 No Joint and Several Liability. Notwithstanding anything to the contrary in this Agreement, all representations, warranties, covenants, liabilities and obligations under this Agreement are several, and not joint, to each Shareholder, and no Shareholder will be liable for any breach, default, liability or other obligation of the other Shareholder party to this Agreement.

SECTION 6.18 Rule 144 Information. The Company covenants that it will use its reasonable best efforts to timely file all reports and other documents required to be filed by it under the Securities Act and the Exchange Act and the rules and regulations promulgated by the SEC thereunder (or, if the Company is not required to file such reports, it will, upon the request of any Shareholder, make publicly available such information as necessary to permit sales pursuant to Rule 144 or Regulation S under the Securities Act), and it will use reasonable best efforts to take such further action as any Shareholder may reasonably request, in each case to the extent required from time to time to enable such holder to sell the securities of the Company without registration under the Securities Act within the limitation of the exemptions provided by (i) Rule144 or Regulation S under the Securities Act, as such rules may be amended from time to time, or (ii) any successor rule or regulation hereafter adopted by the SEC. Upon the written request of any Shareholder, the Company will deliver to such Shareholder a written statement that it has complied with such requirements.
