2. REGISTRATION RIGHTS.

2.1 Demand Registration.

2.1.1 Request for Registration. Subject to this Section 2.1.1 and Section 2.4, at any time within one year after the Closing, Investors holding a majority-in-interest of the Registrable Securities then issued and outstanding may make a written demand for registration under the Securities Act of all or part of their Registrable Securities (a “Demand Registration”). Any demand for a Demand Registration shall specify the number of Registrable Securities proposed to be sold and the intended method(s) of distribution thereof. Within ten (10) days following receipt of any request for a Demand Registration, the PubCo will notify all other Investors holding Registrable Securities of the demand, and each Investor holding Registrable Securities who wishes to include all or a portion of such Investor’s Registrable Securities in the Demand Registration (each such Investor including shares of Registrable Securities in such registration, a “Demanding Holder”) shall so notify the PubCo within fifteen (15) days after the receipt by the Investor of the notice from the PubCo. Upon any such request, the Demanding Holders shall be entitled to have their Registrable Securities included in the Demand Registration, subject to Section 2.1.4 and the provisos set forth in Section 3.1.1. The PubCo shall not be obligated to effect more than an aggregate of two (2) Demand Registrations under this Section 2.1.1 in respect of all Registrable Securities.

2.1.2 Effective Registration. A Registration will not count as a Demand Registration until the Registration Statement filed with the SEC with respect to such Demand Registration has been declared effective and the PubCo has complied in all material respects with its obligations under this Agreement with respect thereto; provided, however, that if, after such Registration Statement has been declared effective, the offering of Registrable Securities pursuant to a Demand Registration is interfered with by any stop order or injunction of the SEC or any other governmental agency or court, the Registration Statement with respect to such Demand Registration will be deemed not to have been declared effective, unless and until, (i) such stop order or injunction is removed, rescinded or otherwise terminated, and (ii) a majority-in-interest of the Demanding Holders thereafter elect to continue with such Registration; provided, further, that the PubCo shall not be obligated to file a second Registration Statement until a Registration Statement that has been filed is counted as a Demand Registration or is terminated.

2.1.3 Underwritten Offering. If a majority-in-interest of the Demanding Holders so elect and advise PubCo as part of their written demand for a Demand Registration, the offering of such Registrable Securities pursuant to such Demand Registration shall be in the form of an underwritten offering. In such event, the right of any Demanding Holder to include its Registrable Securities in such registration shall be conditioned upon such Demanding Holder’s participation in such underwritten offering and the inclusion of such Demanding Holder’s Registrable Securities in the underwritten offering to the extent provided herein. All Demanding Holders proposing to distribute their Registrable Securities through such underwritten offering shall enter into an underwriting agreement in customary form with the Underwriter or Underwriters selected for such underwritten offering by a majority-in-interest of the Investors initiating the Demand Registration.

2.1.4 Reduction of Offering. If the managing Underwriter or Underwriters for a Demand Registration that is to be an underwritten offering, in good faith, advises the PubCo and the Demanding Holders in writing that the dollar amount or number of Registrable Securities which the Demanding Holders desire to sell, taken together with all other shares of Purchaser Common Stock or other securities which the PubCo desires to sell and the shares of Purchaser Common Stock or other securities, if any, as to which Registration by the PubCo has been requested pursuant to written contractual piggy-back registration rights held by other security holders of the PubCo who desire to sell, exceeds the maximum dollar amount or maximum number of shares that can be sold in such offering without adversely affecting the proposed offering price, the timing, the distribution method, or the probability of success of such offering (such maximum dollar amount or maximum number of securities, as applicable, the “Maximum Number of Securities” ), then the PubCo shall include in such Registration: (i) first, the Registrable Securities as to which Demand Registration has been requested by the Demanding Holders and the Founder Securities for the account of any Persons who have exercised demand registration rights pursuant to the Founder Registration Rights Agreement during the period under which the Demand Registration hereunder is ongoing (all pro rata in accordance with the number of securities that each applicable Person has requested be included in such registration, regardless of the number of securities held by each such Person, as long as they do not request to include more securities than they own (such proportion is referred to herein as “Pro Rata”)) that can be sold without exceeding the Maximum Number of Securities; (ii) second, to the extent that the Maximum Number of Securities has not been reached under the foregoing clause (i) the Registrable Securities of Investors as to which registration has been requested pursuant to Section 2.2 and the Founder Securities as to which registration has been requested pursuant to the applicable written contractual piggy-back registration rights of the Founder Registration Rights Agreement, Pro Rata among the holders thereof based on the number of securities requested by such holders to be included in such registration, that can be sold without exceeding the Maximum Number of Securities; and (iii) third, to the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (i) and (ii), the shares of Purchaser Common Stock or other securities that the PubCo desires to sell that can be sold without exceeding the Maximum Number of Securities. In the event that the PubCo securities that are convertible into shares of Purchaser Common Stock are included in the offering, the calculations under this Section 2.1.4 shall include such PubCo securities on an as-converted to Purchaser Common Stock basis.

2.1.5 Withdrawal. A Demanding Holder may withdraw all or any portion of their Registrable Securities included in a Demand Registration from such Demand Registration at any time prior to the effectiveness of the Demand Registration Statement. If a majority-in-interest of the Demanding Holders disapprove of the terms of any underwritten offering or are not entitled to include all of their Registrable Securities in any offering, such majority- in-interest of the Demanding Holders may elect to withdraw from such offering by giving written notice to the PubCo and the Underwriter or Underwriters of their request to withdraw prior to the effectiveness of the Registration Statement filed with the SEC with respect to such Demand Registration. If the majority-in-interest of the Demanding Holders withdraws from a proposed offering relating to a Demand Registration in such event, then such registration shall not count as a Demand Registration provided for in Section 2.1. Notwithstanding any such withdrawal, the PubCo shall pay all expenses incurred by the holders of Registrable Securities in connection with such Demand Registration as provided in Section 3.3.

2.2 Piggy-Back Registration.

2.2.1 Piggy-Back Rights. Subject to Section 2.4, if at any time after the Closing the PubCo proposes to file a Registration Statement under the Securities Act with respect to the Registration of or an offering of equity securities, or securities or other obligations exercisable or exchangeable for, or convertible into, equity securities, by the PubCo for its own account or for security holders of the PubCo for their account (or by the PubCo and by security holders of the PubCo including pursuant to Section 2.1), other than a Registration Statement (i) filed in connection with any employee share option or other benefit plan, (ii) for an exchange offer or offering of securities solely to the PubCo’s existing security holders, (iii) for an offering of debt that is convertible into equity securities of the PubCo, or (iv) for a dividend reinvestment plan, then the PubCo shall (x) give written notice of such proposed filing to Investors holding Registrable Securities as soon as practicable but in no event less than ten (10) days before the anticipated filing date or confidential submission date, which notice shall describe the amount and type of securities to be included in such Registration or offering, the intended method(s) of distribution, and the name of the proposed managing Underwriter or Underwriters, if any, of the offering, and (y) offer to Investors holding Registrable Securities in such notice the opportunity to register the sale of such number of Registrable Securities as such Investors may request in writing within five (5) days following receipt of such notice (a “Piggy-Back Registration”). To the extent permitted by applicable securities laws with respect to such registration by the PubCo or another demanding security holder, the PubCo shall use its best efforts to cause (i) such Registrable Securities to be included in such registration and (ii) the managing Underwriter or Underwriters of a proposed underwritten offering to permit the Registrable Securities requested to be included in a Piggy-Back Registration on the same terms and conditions as any similar securities of the PubCo and to permit the sale or other disposition of such Registrable Securities in accordance with the intended method(s) of distribution thereof. All Investors holding Registrable Securities proposing to distribute their securities through a Piggy-Back Registration that involves an Underwriter or Underwriters shall enter into an underwriting agreement in customary form with the Underwriter or Underwriters selected for such Piggy-Back Registration.

2.2.2 Reduction of Offering. If the managing Underwriter or Underwriters for a Piggy-Back Registration that is to be an underwritten offering, in good faith, advises the PubCo and Investors holding Registrable Securities proposing to distribute their Registrable Securities through such Piggy-Back Registration in writing that the dollar amount or number of shares of Purchaser Common Stock or other PubCo securities which the PubCo desires to sell, taken together with the shares of Purchaser Common Stock or other PubCo securities, if any, as to which registration has been demanded pursuant to written contractual arrangements with Persons other than the Investors holding Registrable Securities hereunder, the Registrable Securities as to which registration has been requested under this Section 2.2, and the shares of Purchaser Common Stock or other PubCo securities, if any, as to which registration has been requested pursuant to the written contractual piggy-back registration rights of other security holders of the PubCo, exceeds the Maximum Number of Securities, then the PubCo shall include in any such registration:

(a) If the registration is undertaken for the PubCo’s account: (i) first, the shares of Purchaser Common Stock or other securities that the PubCo desires to sell that can be sold without exceeding the Maximum Number of Securities; (ii) second, to the extent that the Maximum Number of Securities has not been reached under the foregoing clause (i), the Registrable Securities of Investors as to which registration has been requested pursuant to this Section 2.2 and the Founder Securities as to which registration has been requested pursuant to the applicable written contractual piggy-back registration rights under the Founder Registration Rights Agreement, Pro Rata among the holders thereof based on the number of securities requested by such holders to be included in such registration, that can be sold without exceeding the Maximum Number of Securities; and (iii) third, to the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (i) and (ii), the shares of Purchaser Common Stock or other equity securities for the account of other Persons that the PubCo is obligated to register pursuant to separate written contractual arrangements with such Persons that can be sold without exceeding the Maximum Number of Securities;

3.1.1 Filing Registration Statement. The PubCo shall use its best efforts to, as expeditiously as possible after receipt of a request for a Demand Registration pursuant to Section 2.1, prepare and file with the SEC a Registration Statement on any form for which the PubCo then qualifies or which counsel for the PubCo shall deem appropriate and which form shall be available for the sale of all Registrable Securities to be registered thereunder in accordance with the intended method(s) of distribution thereof, and shall use its reasonable efforts to cause such Registration Statement to become effective and use its reasonable efforts to keep it effective for the period required by Section 3.1.3; provided, however, that the PubCo shall have the right to defer any Demand Registration for up to thirty (30) days, and any Piggy-Back Registration for such period as may be applicable to deferment of any demand registration to which such Piggy-Back Registration relates, in each case if the PubCo shall furnish to Investors requesting to include their Registrable Securities in such registration a certificate signed by the Chief Executive Officer, Chief Financial Officer or Chairman of the PubCo stating that, in the good faith judgment of the Board of Directors of the PubCo, it would be materially detrimental to the PubCo and its shareholders for such Registration Statement to be effected at such time or the filing would require premature disclosure of material information which is not in the interests of the PubCo to disclose at such time; provided further, however, that the PubCo shall not have the right to exercise the right set forth in the immediately preceding proviso more than once in any 365-day period in respect of a Demand Registration hereunder.

3.1.2 Copies. The PubCo shall, prior to filing a Registration Statement or prospectus, or any amendment or supplement thereto, furnish without charge to Investors holding Registrable Securities included in such registration, and such Investors’ legal counsel, copies of such Registration Statement as proposed to be filed, each amendment and supplement to such Registration Statement (in each case including all exhibits thereto and documents incorporated by reference therein), the prospectus included in such Registration Statement (including each preliminary prospectus), and such other documents as Investors holding Registrable Securities included in such registration or legal counsel for any such Investors may request in order to facilitate the disposition of the Registrable Securities owned by such Investors.

The PubCo shall prepare and file with the SEC such amendments, including post-effective amendments, and supplements to such Registration Statement and the prospectus used in connection therewith as may be necessary to keep such Registration Statement effective and in compliance with the provisions of the Securities Act until all Registrable Securities and other securities covered by such Registration Statement have been disposed of in accordance with the intended method(s) of distribution set forth in such Registration Statement or such securities have been withdrawn or until such time as the Registrable Securities cease to be Registrable Securities as defined by this Agreement.

3.1.4 Reporting Obligations. As long as any Investors shall own Registrable Securities, the PubCo, at all times while it shall be a reporting company under the Exchange Act, covenants to file timely (or obtain extensions in respect thereof and file within the applicable grace period) all reports required to be filed by the PubCo after the date hereof pursuant to Sections 13(a) or 15(d) of the Exchange Act and to promptly furnish the Holders with true and complete copies of all such filings; provided that any documents publicly filed or furnished with the SEC pursuant to the Electronic Data Gathering, Analysis and Retrieval System shall be deemed to have been furnished or delivered to the Holders pursuant to this Section 3.1.4.

3.1.5 Other Obligations. In connection with a sale or transfer of Registrable Securities exempt from Section 5 of the Securities Act or through any broker-dealer transactions described in the plan of distribution set forth within the prospectus included in the Registration Statement, the PubCo shall, subject to the receipt of the any customary documentation reasonably required from the applicable Investors in connection therewith, (a) promptly instruct its transfer agent to remove any restrictive legends applicable to the Registrable Securities being sold or transferred and (b) cause its legal counsel to deliver the necessary legal opinions, if any, to the transfer agent in connection with the instruction under subclause (a).

3.1.5 State Securities Laws Compliance. The PubCo shall use its reasonable efforts to (i) register or qualify the Registrable Securities covered by the Registration Statement under such securities or “blue sky” laws of such jurisdictions in the United States as Investors holding Registrable Securities included in such Registration Statement (in light of their intended plan of distribution) may reasonably request and (ii) take such action necessary to cause such Registrable Securities covered by the Registration Statement to be registered with or approved by such other governmental authorities as may be necessary by virtue of the business and operations of the PubCo and do any and all other acts and things that may be necessary or advisable to enable Investors holding Registrable Securities included in such Registration Statement to consummate the disposition of such Registrable Securities in such jurisdictions; provided, however, that the PubCo shall not be required to qualify generally to do business in any jurisdiction where it would not otherwise be required to qualify but for this paragraph or take any action to which it would be subject to general service of process or to taxation in any such jurisdiction where it is not then otherwise subject.

3.1.6 Agreements for Disposition. To the extent required by the underwriting agreement or similar agreements, the PubCo shall enter into reasonable customary agreements (including, if applicable, an underwriting agreement in customary form) and take such other actions as are reasonably required in order to expedite or facilitate the disposition of such Registrable Securities. The representations, warranties and covenants of the PubCo in any underwriting agreement which are made to or for the benefit of any Underwriters, to the extent applicable, shall also be made to and for the benefit of Investors holding Registrable Securities included in such Registration Statement.

3.1.11 Listing. The PubCo shall use its best efforts to cause all Registrable Securities that are shares of Purchaser Common Stock included in any registration to be listed on such national security exchange as similar securities issued by the PubCo are then listed or, if no such similar securities are then listed, in a manner satisfactory to Investors holding a majority-in-interest of the Registrable Securities included in such registration.

3.2 Obligation to Suspend Distribution. Upon receipt of any notice from the PubCo of the happening of any event of the kind described in Section 3.1.4(iv), or in the event that the financial statements contained in the Registration Statement become stale, or in the event that the Registration Statement or prospectus included therein contains a misstatement of material fact or omits to state a material fact due to a bona fide business purpose, or, in the case of a resale registration on Short Form Registration pursuant to Section 2.3 hereof, upon any suspension by the PubCo, pursuant to a written insider trading compliance program adopted by the PubCo’s Board of Directors, of the ability of all “insiders” covered by such program to transact in the PubCo’s securities because of the existence of material non-public information, each Investor holding Registrable Securities included in any registration shall immediately discontinue disposition of such Registrable Securities pursuant to the Registration Statement covering such Registrable Securities until such Investor receives the supplemented or amended prospectus contemplated by Section 3.1.4(iv) or the Registration Statement is updated so that the financial statements are no longer stale, or the restriction on the ability of “insiders” to transact in the PubCo’s securities is removed, as applicable, and, if so directed by the PubCo, each such Investor will deliver to the PubCo all copies, other than permanent file copies then in such Investor’s possession, of the most recent prospectus covering such Registrable Securities at the time of receipt of such notice.

Investors selling Registrable Securities in any offering must provide all questionnaires, powers of attorney, custody agreements, stock powers, and other documentation reasonably requested by the PubCo or the managing Underwriter.

4. INDEMNIFICATION AND CONTRIBUTION.

4.1 Indemnification by PubCo. Subject to the provisions of this Section 4.1 below, the PubCo agrees to indemnify and hold harmless each Investor, and each Investor’s officers, employees, affiliates, directors, partners, members, attorneys and agents, and each Person, if any, who controls an Investor (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) (each, an “Investor Indemnified Party”), from and against any expenses, losses, judgments, claims, damages or liabilities, whether joint or several, arising out of or based upon any untrue or alleged untrue statement of a material fact contained in any Registration Statement under which the sale of such Registrable Securities was registered under the Securities Act, any preliminary prospectus, final prospectus or summary prospectus contained in the Registration Statement, or any amendment or supplement to such Registration Statement, or arising out of or based upon any omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading, or any violation by the PubCo of the Securities Act or any rule or regulation promulgated thereunder applicable to the PubCo and relating to action or inaction required of the PubCo in connection with any such registration (provided, however, that the indemnity agreement contained in this Section 4.1 shall not apply to amounts paid in settlement of any such claim, loss, damage, liability or action if such settlement is effected without the consent of the PubCo, such consent not to be unreasonably withheld, delayed or conditioned); and the PubCo shall promptly reimburse the Investor Indemnified Party for any legal and any other expenses reasonably incurred by such Investor Indemnified Party in connection with investigating and defending any such expense, loss, judgment, claim, damage, liability or action; provided, however, that the PubCo will not be liable in any such case to the extent that any such expense, loss, claim, damage or liability arises out of or is based upon any untrue or alleged untrue statement or omission or alleged omission made in such Registration Statement, preliminary prospectus, final prospectus, or summary prospectus, or any such amendment or supplement, in reliance upon and in conformity with information furnished to the PubCo, in writing, by such selling holder or Investor Indemnified Party expressly for use therein. The PubCo also shall indemnify any Underwriter of the Registrable Securities, their officers, affiliates, directors, partners, members and agents and each Person who controls such Underwriter on substantially the same basis as that of the indemnification provided above in this Section 4.1.

4.2 Indemnification by Holders of Registrable Securities. Subject to the provisions of this Section 4.2 below, each Investor selling Registrable Securities will, in the event that any registration is being effected under the Securities Act pursuant to this Agreement of any Registrable Securities held by such selling Investor, indemnify and hold harmless the PubCo, each of its directors and officers and each Underwriter (if any), and each other selling holder and each other Person, if any, who controls another selling holder or such Underwriter within the meaning of the Securities Act, against any losses, claims, judgments, damages or liabilities, whether joint or several, insofar as such losses, claims, judgments, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement of a material fact contained in any Registration Statement under which the sale of such Registrable Securities was registered under the Securities Act, any preliminary prospectus, final prospectus or summary prospectus contained in the Registration Statement, or any amendment or supplement to the Registration Statement, or arise out of or are based upon any omission or alleged omission to state a material fact required to be stated therein or necessary to make the statement therein not misleading, if the statement or omission was made in reliance upon and in conformity with information furnished in writing to the PubCo by such selling Investor expressly for use therein (provided, however, that the indemnity agreement contained in this Section 4.2 shall not apply to amounts paid in settlement of any such claim, loss, damage, liability or action if such settlement is effected without the consent of the indemnifying Investor, such consent not to be unreasonably withheld, delayed or conditioned), and shall reimburse the PubCo, its directors and officers, each Underwriter and each other selling holder or controlling Person for any legal or other expenses reasonably incurred by any of them in connection with investigation or defending any such loss, claim, damage, liability or action. Each selling Investor’s indemnification obligations hereunder shall be several and not joint and shall be limited to the amount of any net proceeds actually received by such selling Investor in the applicable offering.

4.3 Conduct of Indemnification Proceedings. Promptly after receipt by any Person of any notice of any loss, claim, damage or liability or any action in respect of which indemnity may be sought pursuant to Section 4.1 or 4.2, such Person (the “Indemnified Party”) shall, if a claim in respect thereof is to be made against any other Person for indemnification hereunder, notify such other Person (the “Indemnifying Party”) in writing of the loss, claim, judgment, damage, liability or action; provided, however, that the failure by the Indemnified Party to notify the Indemnifying Party shall not relieve the Indemnifying Party from any liability which the Indemnifying Party may have to such Indemnified Party hereunder, except and solely to the extent the Indemnifying Party is actually prejudiced by such failure. If the Indemnified Party is seeking indemnification with respect to any claim or action brought against the Indemnified Party, then the Indemnifying Party shall be entitled to participate in such claim or action, and, to the extent that it wishes, jointly with all other Indemnifying Parties, to assume control of the defense thereof with counsel satisfactory to the Indemnified Party if the Indemnifying Party provides notice of such to the Indemnified Party within thirty (30) days of the Indemnifying Party’s receipt of notice of such claim. After notice from the Indemnifying Party to the Indemnified Party of its election to assume control of the defense of such claim or action, the Indemnifying Party shall not be liable to the Indemnified Party for any legal or other expenses subsequently incurred by the Indemnified Party in connection with the defense thereof other than reasonable costs of investigation; provided, however, that in any action in which both the Indemnified Party and the Indemnifying Party are named as defendants, the Indemnified Party shall have the right to employ separate counsel (but no more than one such separate counsel) to represent the Indemnified Party and its controlling Persons who may be subject to liability arising out of any claim in respect of which indemnity may be sought by the Indemnified Party against the Indemnifying Party, with the fees and expenses of such counsel to be paid by such Indemnifying Party if, based upon the written opinion of counsel of such Indemnified Party, representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. No Indemnifying Party shall, without the prior written consent of the Indemnified Party (acting reasonably), consent to entry of judgment or effect any settlement of any claim or pending or threatened proceeding in respect of which the Indemnified Party is or could have been a party and indemnity could have been sought hereunder by such Indemnified Party, unless such judgment or settlement includes an unconditional release of such Indemnified Party from all liability arising out of such claim or proceeding.

4.4 Contribution.

4.4.1 If the indemnification provided for in the foregoing Sections 4.1, 4.2 and 4.3 is unavailable to any Indemnified Party in respect of any loss, claim, damage, liability or action referred to herein, then each such Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall contribute to the amount paid or payable by such Indemnified Party as a result of such loss, claim, damage, liability or action in such proportion as is appropriate to reflect the relative fault of the Indemnified Parties and the Indemnifying Parties in connection with the actions or omissions which resulted in such loss, claim, damage, liability or action, as well as any other relevant equitable considerations. The relative fault of any Indemnified Party and any Indemnifying Party shall be determined by reference to, among other things, whether the untrue statement of a material fact or the omission to state a material fact relates to information supplied by such Indemnified Party or such Indemnifying Party and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

4.4.2 The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 4.4 were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to in the immediately preceding Section 4.4.1.

4.4.3 The amount paid or payable by an Indemnified Party as a result of any loss, claim, damage, liability or action referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, any legal or other expenses incurred by such Indemnified Party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 4.4, no Investor holding Registrable Securities shall be required to contribute any amount in excess of the dollar amount of the net proceeds (after payment of any underwriting fees, discounts, commissions or taxes) actually received by such Investor from the sale of Registrable Securities which gave rise to such contribution obligation. Any contributions obligation of the Investors shall be several and not joint. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation.

5. RULE 144 AND 145.

5.1 Rule 144 and 145. The PubCo covenants that it shall file any reports required to be filed by it under the Securities Act and the Exchange Act and shall take such further action as Investors holding Registrable Securities may reasonably request, all to the extent required from time to time to enable such Investors to sell Registrable Securities without registration under the Securities Act within the limitation of the exemptions provided by Rule 144 and 145 under the Securities Act, as such Rule 144 and 145 may be amended from time to time, or any similar rule or regulation hereafter adopted by the SEC. Upon the request of any holder of Registrable Securities, the PubCo shall deliver to such Holder a written certification of a duly authorized officer as to (A) whether the PubCo has filed (i) all reports and other materials required to be filed pursuant to Sections 13(a) or 15(d) of the Exchange Act, as applicable, during the preceding 12 months (or for such shorter period that the PubCo was required to file such reports and materials), other than Current Reports on Form 8-K and (ii) current “Form 10 information” (within the meaning of Rule 144 under the Securities Act) with the Commission reflecting the PubCo’s status as an entity that is no longer an issuer described in paragraph (i)(1)(i) of Rule 144 under the Securities Act and (B) the first date that the PubCo filed “Form 10 information” (within the meaning of Rule 144 under the Securities Act) with the Commission.

6. MISCELLANEOUS.

6.1 Other Registration Rights. The PubCo represents and warrants that as of the date of this Agreement, no Person, other than the holders of (i) Registrable Securities, and (ii) Founder Securities, has any right to require the PubCo to register any of the PubCo’s share capital for sale or to include the PubCo’s share capital in any registration filed by the PubCo for the sale of share capital for its own account or for the account of any other Person.

6.2 Assignment; No Third Party Beneficiaries. This Agreement and the rights, duties and obligations of the PubCo hereunder may not be assigned or delegated by the PubCo in whole or in part, unless the PubCo first provides Investors holding Registrable Securities at least ten (10) Business Days prior written notice; provided that no assignment or delegation by the PubCo will relieve the PubCo of its obligations under this Agreement unless Investors holding a majority-in-interest of the Registrable Securities provide their prior written consent, which consent must not be unreasonably withheld, delayed or conditioned. This Agreement and the rights, duties and obligations of Investors holding Registrable Securities hereunder may be freely assigned or delegated by such Investor in conjunction with and to the extent of any transfer of Registrable Securities by such Investor which is permitted by the Lock-Up Agreement; provided that no assignment by any Investor of its rights, duties and obligations hereunder shall be binding upon or obligate the PubCo unless and until the PubCo shall have received (i) written notice of such assignment and (ii) the written agreement of the assignee, in a form reasonably satisfactory to the PubCo, to be bound by the terms and provisions of this Agreement (which may be accomplished by an addendum or certificate of joinder to this Agreement). This Agreement and the provisions hereof shall be binding upon and shall inure to the benefit of each of the parties, to the permitted assigns of the Investors or of any assignee of the Investors. This Agreement is not intended to confer any rights or benefits on any Persons that are not party hereto other than as expressly set forth in Section 4 and this Section 6.2.

6.3 Notices. All notices, consents, waivers and other communications hereunder shall be in writing and shall be deemed to have been duly given when delivered (i) in person, (ii) by facsimile or other electronic means, with affirmative confirmation of receipt, (iii) one Business Day after being sent, if sent by reputable, nationally recognized overnight courier service or (iv) three (3) Business Days after being mailed, if sent by registered or certified mail, pre- paid and return receipt requested, in each case to the applicable party at the following addresses (or at such other address for a party as shall be specified by like notice):

6.4 Severability. This Agreement shall be deemed severable, and the invalidity or unenforceability of any term or provision hereof shall not affect the validity or enforceability of this Agreement or of any other term or provision hereof. Furthermore, in lieu of any such invalid or unenforceable term or provision, the parties hereto intend that there shall be added as a part of this Agreement a provision as similar in terms to such invalid or unenforceable provision as may be possible that is valid and enforceable. Notwithstanding anything to the contrary contained in this Agreement, in the event that a duly executed copy of this Agreement is not delivered to PubCo by a Person receiving Merger Consideration Shares in connection with the Closing, such Person failing to provide such signature shall not be a party to this Agreement or have any rights or obligations hereunder, but such failure shall not affect the rights and obligations of the other parties to this Agreement as amongst such other parties.

6.5 Entire Agreement. This Agreement (together with the Business Combination Agreement, and the Lock-Up Agreement to the extent incorporated herein, and including all agreements entered into pursuant hereto or thereto or referenced herein or therein and all certificates and instruments delivered pursuant hereto and thereto) constitutes the entire agreement of the parties with respect to the subject matter hereof and supersedes all prior and contemporaneous agreements, representations, understandings, negotiations and discussions between the parties, whether oral or written, relating to the subject matter hereof; provided, that, for the avoidance of doubt, the foregoing shall not affect the rights and obligations of the parties under the Business Combination Agreement or any other Ancillary Document or the rights or obligations of the parties under the Founder Registration Rights Agreement.

6.6 Interpretation. Titles and headings of sections of this Agreement are for convenience only and shall not affect the construction of any provision of this Agreement. In this Agreement, unless the context otherwise requires: (i) any pronoun used in this Agreement shall include the corresponding masculine, feminine or neuter forms, and the singular form of nouns, pronouns and verbs shall include the plural and vice versa; (ii) “including” (and with correlative meaning “include”) means including without limiting the generality of any description preceding or succeeding such term and shall be deemed in each case to be followed by the words “without limitation”; (iii) the words “herein,” “hereto,” and “hereby” and other words of similar import in this Agreement shall be deemed in each case to refer to this Agreement as a whole and not to any particular section or other subdivision of this Agreement; and (iv) the term “or” means “and/or”. The parties have participated jointly in the negotiation and drafting of this Agreement. Consequently, in the event an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the parties hereto, and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of any provision of this Agreement.

6.7 Amendments; Waivers. Any term of this Agreement may be amended and the observance of any term of this Agreement may be waived (either generally or in a particular instance, and either retroactively or prospectively) only with the written agreement or consent of the PubCo (after the Closing by a majority of the Disinterested Independent Directors) and Investors holding a majority-in-interest of the Registrable Securities; provided, that any amendment or waiver of this Agreement which affects an Investor in a manner materially and adversely disproportionate to other Investors will also require the consent of such Investor. No failure or delay by a party in exercising any right hereunder shall operate as a waiver thereof. No waivers of or exceptions to any term, condition, or provision of this Agreement, in any one or more instances, shall be deemed to be or construed as a further or continuing waiver of any such term, condition, or provision.

6.8 Remedies Cumulative. In the event a party fails to observe or perform any covenant or agreement to be observed or performed under this Agreement, the other parties may proceed to protect and enforce its rights by suit in equity or action at law, whether for specific performance of any term contained in this Agreement or for an injunction against the breach of any such term or in aid of the exercise of any power granted in this Agreement or to enforce any other legal or equitable right, or to take any one or more of such actions, without being required to post a bond. None of the rights, powers or remedies conferred under this Agreement shall be mutually exclusive, and each such right, power or remedy shall be cumulative and in addition to any other right, power or remedy, whether conferred by this Agreement or now or hereafter available at law, in equity, by statute or otherwise.

6.9 Governing Law; Jurisdiction. Sections 10.6 and 10.7 of the Business Combination Agreement shall apply to this Agreement mutatis mutandis.

6.10 Termination of Business Combination Agreement. This Agreement shall be binding upon each party upon such party’s execution and delivery of this Agreement, but this Agreement shall only become effective upon the Closing. In the event that the Business Combination Agreement is validly terminated in accordance with its terms prior to the Closing, this Agreement shall automatically terminate and become null and void and be of no further force or effect, and the parties shall have no obligations hereunder.

6.11 Counterparts. This Agreement may be executed in multiple counterparts (including by facsimile or pdf or other electronic document transmission), each of which shall be deemed an original, and all of which taken together shall constitute one and the same instrument. Copies of executed counterparts of this Agreement transmitted by electronic transmission (including by email or in .pdf format) or facsimile as well as electronically or digitally executed counterparts (such as DocuSign) shall have the same legal effect as original signatures and shall be considered original executed counterparts of this Agreement.
