        5

        
          


      

      2.1.1 Initial Registration. The Company shall use its commercially reasonable efforts to file a Registration Statement under the Securities
          Act promptly, but in any event within forty-five (45) days following the Closing, to permit the public resale of all the Registrable Securities held by the Holders from time to time as permitted by Rule 415 under the Securities Act (or any
          successor or similar provision adopted by the Commission then in effect) (“Rule 415”) on the terms and conditions specified in this subsection 2.1.1 and shall use its commercially reasonable efforts to cause such Registration
          Statement to be declared effective as soon as practicable after the filing thereof, but in no event later than sixty (60) days following the filing deadline (the “Effectiveness Deadline”); provided, that the Effectiveness Deadline
          shall be extended to ninety (90) days after the filing deadline if the Registration Statement is reviewed by, and receives comments from, the Commission. The Registration Statement filed with the Commission pursuant to this subsection 2.1.1
          shall be a shelf registration statement on Form S-1 (a “Form S-1”) or such other form of registration statement as is then available to effect a registration for resale of such Registrable Securities, covering such Registrable Securities,
          and shall contain a Prospectus in such form as to permit any Holder to sell such Registrable Securities pursuant to Rule 415 at any time beginning on the effective date for such Registration Statement. A Registration Statement filed pursuant to
          this subsection 2.1.1 shall provide for the resale pursuant to any method or combination of methods legally available to, and requested by, the Holders. The Company shall use its commercially reasonable efforts to cause a Registration
          Statement filed pursuant to this subsection 2.1.1 to remain effective, and to be supplemented and amended to the extent necessary to ensure that such Registration Statement is available or, if not available, that another Registration
          Statement is available, for the resale of all the Registrable Securities held by the Holders until all such Registrable Securities have ceased to be Registrable Securities. As soon as practicable following the effective date of a Registration
          Statement filed pursuant to this subsection 2.1.1, but in any event within two (2) business days of such date, the Company shall notify the Holders of the effectiveness of such Registration Statement. When effective, a Registration
          Statement filed pursuant to this subsection 2.1.1 (including documents incorporated therein by reference) will comply as to form in all material respects with all applicable requirements of the Securities Act and the Exchange Act and will
          not contain a Misstatement.

       

      2.1.2 Form S-3. The Company shall use its commercially reasonable efforts to file a shelf registration statement on Form S-3 (“Form S-3”)
          as soon as practicable after the Company is eligible to use Form S-3.

       

      2.1.3 Shelf Takedown. At any time and from time to time following the effectiveness of the shelf registration statement required by subsection
            2.1.1 or 2.1.2, any Holder(s) may request to sell all or a portion of their Registrable Securities in an Underwritten Offering that is registered pursuant to such shelf registration statement (a “Shelf Underwritten Offering”)
          provided that such Holder(s) (a) reasonably expect aggregate gross proceeds in excess of $10,000,000 from such Shelf Underwritten Offering or (b) reasonably expects to sell all of the Registrable Securities held by such Holder in such Shelf
          Underwritten Offering but in no event for less than $5,000,000 in gross proceeds. All requests for a Shelf Underwritten Offering shall be made by giving written notice to the Company (the “Shelf Takedown Notice”). Each Shelf Takedown
          Notice shall specify the approximate number of Registrable Securities proposed to be sold in the Shelf Underwritten Offering and the expected price range (net of underwriting discounts and commissions) of such Shelf Underwritten Offering. Within
          five (5) business days after receipt of any Shelf Takedown Notice, the Company shall give written notice of such requested Shelf Underwritten Offering to all other Holders of Registrable Securities (the “Company Shelf Takedown Notice”)
          and, subject to reductions consistent with the pro rata calculations in subsection 2.2.4, shall include in such Shelf Underwritten Offering all Registrable Securities with respect to which the Company has received written requests for
          inclusion therein, within five (5) days after sending the Company Shelf Takedown Notice. The Company shall enter into an underwriting agreement in a form as is customary in Underwritten Offerings of securities by the Company with the managing
          Underwriter or Underwriters selected by the initiating Holder(s) after consultation with the Company and shall take all such other reasonable actions as are requested by the managing Underwriter or Underwriters in order to expedite or facilitate
          the disposition of such Registrable Securities. In connection with any Shelf Underwritten Offering contemplated by this subsection 2.1.3, subject to Section 3.4 and Article IV, the underwriting agreement into which each
          Holder and the Company shall enter shall contain such representations, covenants, indemnities and other rights and obligations of the Company and the selling stockholders as are customary in Underwritten Offerings of securities by the Company.

      2.2 Demand Registration.

       

      2.2.1 Request for Registration. Subject to the provisions of subsection 2.2.4 hereof and provided that the Company does not have an
          effective Registration Statement pursuant to subsection 2.1 outstanding covering the Registrable Securities, the Holders of at least a majority-in-interest of the then outstanding number of Registrable Securities held by the Accelus
          Holders or the Sponsor Group Holders (the “Demanding Holders”), in each case, may make a written demand for Registration of all or part of their Registrable Securities, which written demand shall describe the amount and type of securities
          to be included in such Registration and the intended method(s) of distribution thereof (such written demand a “Demand Registration”). The Company shall, within ten (10) days of the Company’s receipt of the Demand Registration, notify, in
          writing, all other Holders of Registrable Securities of such demand, and each Holder of Registrable Securities who thereafter wishes to include all or a portion of such Holder’s Registrable Securities in a Registration pursuant to a Demand
          Registration (each such Holder that includes all or a portion of such Holder’s Registrable Securities in such Registration, a “Requesting Holder”) shall so notify the Company, in writing, within five (5) days after the receipt by the
          Holder of the notice from the Company. Upon receipt by the Company of any such written notification from a Requesting Holder(s) to the Company, such Requesting Holder(s) shall be entitled to have their Registrable Securities included in a
          Registration pursuant to a Demand Registration and the Company shall effect, as soon thereafter as practicable, the Registration of all Registrable Securities requested by the Demanding Holders and Requesting Holders pursuant to such Demand
          Registration, including by filing a Registration Statement relating thereto as soon as practicable, but not more than forty-five (45) days immediately after the Company’s receipt of the Demand Registration. Under no circumstances shall the
          Company be obligated to effect more than an aggregate of three (3) Registrations pursuant to a Demand Registration under this subsection 2.1.1 with respect to any or all Registrable Securities; provided, however, that a
          Registration pursuant to a Demand Registration shall not be counted for such purposes unless a Registration Statement with respect to such Demand Registration has become effective and all of the Registrable Securities requested by the Requesting
          Holders and the Demanding Holders to be registered on behalf of the Requesting Holders and the Demanding Holders on such Registration Statement have been sold, in accordance with Section 3.1 of this Agreement.

       

      2.2.2 Effective Registration. Notwithstanding the provisions of subsection 2.2.1 above or any other part of this Agreement, a
          Registration pursuant to a Demand Registration shall not count as a Registration unless and until (i) the Registration Statement filed with the Commission with respect to a Registration pursuant to a Demand Registration has been declared
          effective by the Commission and (ii) the Company has complied with all of its material obligations under this Agreement with respect thereto; provided, further, that if, after such Registration Statement has been declared
          effective, an offering of Registrable Securities in a Registration pursuant to a Demand Registration is subsequently interfered with by any stop order or injunction of the Commission, federal or state court or any other governmental agency, the
          Registration Statement with respect to such Registration shall 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 initiating such Demand Registration thereafter affirmatively elect to continue with such Registration and accordingly notify the Company in writing, but in no event later than five (5) days, of such election; provided,
          further, that the Company shall not be obligated or required to file another Registration Statement until the Registration Statement that has been previously filed with respect to a Registration pursuant to a Demand Registration becomes
          effective or is subsequently terminated.

      2.2.3 Underwritten Offering. Subject to the provisions of subsection 2.2.4 hereof, if a majority-in-interest of the Demanding Holders
          so advise the Company as part of their Demand Registration that the offering of the Registrable Securities pursuant to such Demand Registration shall be in the form of an Underwritten Offering, then the right of such Demanding Holder or
          Requesting Holder (if any) to include its Registrable Securities in such Registration shall be conditioned upon such Holder’s participation in such Underwritten Offering and the inclusion of such Holder’s Registrable Securities in such
          Underwritten Offering to the extent provided herein. All such Holders proposing to distribute their Registrable Securities through an Underwritten Offering under this subsection 2.2.3 shall enter into an underwriting agreement in
          customary form with the Underwriter(s) selected for such Underwritten Offering by the majority-in-interest of the Demanding Holders initiating the Demand Registration, which Underwriter(s) shall be reasonably satisfactory to the Company.

       

      2.2.4 Reduction of Underwritten Offering. If the managing Underwriter or Underwriters in an Underwritten Registration pursuant to a Demand
          Registration, in good faith, advises the Company, the Demanding Holders and the Requesting Holders (if any) in writing that the dollar amount or number of Registrable Securities that the Demanding Holders and the Requesting Holders (if any)
          desire to sell, taken together with all other Common Stock or other equity securities that the Company desires to sell and the Common Stock, if any, as to which a Registration has been requested pursuant to separate written contractual piggy-back
          registration rights held by any other stockholders who desire to sell, exceeds the maximum dollar amount or maximum number of equity securities that can be sold in the Underwritten 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 such securities, as applicable, the “Maximum Number of Securities”), then the Company shall include in
          such Underwritten Offering, as follows: (i) first, the Registrable Securities of the Demanding Holders and the Requesting Holders (if any) (pro rata based on the respective number of Registrable Securities that each Demanding Holder and

          Registration) 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 Holders (pro
          rata, based on the respective number of Registrable Securities that each Holder has so requested) exercising their rights to register their Registrable Securities pursuant to subsection 2.3.1 hereof, 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 Common Stock or other equity securities that the Company desires to sell, which can be sold

      2.2.5 Demand Registration Withdrawal. A majority-in-interest of the Demanding Holders initiating a Demand Registration or a
          majority-in-interest of the Requesting Holders (if any), pursuant to a Registration under subsection 2.2.1 shall have the right to withdraw from a Registration pursuant to such Demand Registration or a Shelf Underwritten Offering pursuant
          to subsection 2.1.3 for any or no reason whatsoever upon written notification to the Company and the Underwriter or Underwriters (if any) of their intention to withdraw from such Registration at least two (2) business days prior to the
          effectiveness of the Registration Statement filed with the Commission with respect to the Registration of their Registrable Securities pursuant to such Demand Registration (or in the case of an Underwritten Registration pursuant to Section
            2.1.1 or 2.2.4 at least five (5) business days prior to the time of pricing of the applicable offering). Notwithstanding anything to the contrary in this Agreement, the Company shall be responsible for the Registration Expenses
          incurred in connection with a Registration pursuant to a Demand Registration prior to its withdrawal under this subsection 2.2.5.

       

      2.3 Piggyback Registration.

       

      2.3.1 Piggyback Rights. If the Company proposes to file a Registration Statement under the Securities Act with respect to an offering of
          equity securities, or securities or other obligations exercisable or exchangeable for, or convertible into equity securities, for its own account or for the account of stockholders of the Company (or by the Company and by the stockholders of the
          Company including, without limitation, pursuant to Sections 2.1 and 2.2 hereof), other than a Registration Statement (i) filed in connection with any employee stock option or other benefit plan, (ii) for a rights offering or an
          exchange offer or offering of securities solely to the Company’s then existing stockholders, (iii) for an offering of debt that is convertible into equity securities of the Company or (iv) for a dividend reinvestment plan, then the Company shall
          give written notice of such proposed filing to all of the Holders of Registrable Securities as soon as practicable but not less than ten (10) days before the anticipated filing date of such Registration Statement, which notice shall (A) describe
          the amount and type of securities to be included in such offering, the intended method(s) of distribution, and the name of the proposed managing Underwriter or Underwriters, if any, in such offering, and (B) offer to all of the Holders of
          Registrable Securities the opportunity to register the sale of such number of Registrable Securities as such Holders may request in writing within five (5) days after receipt of such written notice (such Registration a “Piggyback Registration”).
          The Company shall, in good faith, cause such Registrable Securities to be included in such Piggyback Registration and shall use its commercially reasonable efforts to cause the managing Underwriter or Underwriters of a proposed Underwritten
          Offering to permit the Registrable Securities requested by the Holders pursuant to this subsection 2.3.1 to be included in a Piggyback Registration on the same terms and conditions as any similar securities of the Company included in such
          Registration and to permit the sale or other disposition of such Registrable Securities in accordance with the intended method(s) of distribution thereof. All such Holders proposing to distribute their Registrable Securities through an
          Underwritten Offering under this subsection 2.3.1 shall enter into an underwriting agreement in customary form with the Underwriter(s) selected for such Underwritten Offering by the Company. Holders agree that, except as required by
          applicable law, the Holders shall treat as confidential any notice or other communication in connection with any Piggyback Registration and shall not disclose or use the information contained in such notice without the prior written consent of
          the Company until such time as the information contained therein is or becomes public, other than as a result of disclosure by a Holder of Registrable Shares in breach of the terms of this Agreement.

      2.3.2 Reduction of Piggyback Registration. If the managing Underwriter or Underwriters in an Underwritten Registration that is to be a
        Piggyback Registration, in good faith, advises the Company and the Holders of Registrable Securities participating in the Piggyback Registration in writing that the dollar amount or number of the Common Stock that the Company desires to sell, taken
        together with (i) the Common Stock, if any, as to which Registration has been demanded pursuant to separate written contractual arrangements with persons or entities other than the Holders of Registrable Securities hereunder, (ii) the Registrable
        Securities as to which registration has been requested pursuant to Section 2.3 hereof, and (iii) the Common Stock, if any, as to which Registration has been requested pursuant to separate written contractual piggy-back registration rights
        of other stockholders of the Company, exceeds the Maximum Number of Securities, then:

       

      (a) If the Registration is undertaken for the Company’s account, the Company shall include in any such Registration (A) first, the Common Stock or other equity securities that the Company desires to sell, which can be sold
          without exceeding the Maximum Number of Securities; (B) second, to the extent that the Maximum Number of Securities has not been reached under the foregoing clause (A), the Registrable Securities of Holders exercising their rights to register
          their Registrable Securities pursuant to subsection 2.3.1 hereof, pro rata, based on the respective number of Registrable Securities that each Holder has so requested, which can be sold without exceeding the Maximum Number of Securities;
          and (C) third, to the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (A) and (B), the Common Stock, if any, as to which Registration has been requested pursuant to written contractual piggy-back
          registration rights of other stockholders of the Company, which can be sold without exceeding the Maximum Number of Securities;

       

      (b) If the Registration is pursuant to a request by persons or entities other than the Holders of Registrable Securities, then the Company shall
        include in any such Registration (A) first, the Common Stock or other equity securities, if any, of such requesting persons or entities, other than the Holders of Registrable Securities, which can be sold without exceeding the Maximum Number of
        Securities; (B) second, to the extent that the Maximum Number of Securities has not been reached under the foregoing clause (A), the Registrable Securities of Holders exercising their rights to register their Registrable Securities pursuant to subsection
          2.3.1, pro rata, based on the respective number of Registrable Securities that each Holder has requested be included in such Underwritten Registration and the aggregate number of Registrable Securities that the Holders have requested to be
        included in such Underwritten Registration, which can be sold without exceeding the Maximum Number of Securities; (C) third, to the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (A) and (B), the
        Common Stock or other equity securities that the Company desires to sell, which can be sold without exceeding the Maximum Number of Securities; and (D) fourth, to the extent that the Maximum Number of Securities has not been reached under the
        foregoing clauses (A), (B) and (C), the Common Stock or other equity securities for the account of other persons or entities that the Company is obligated to register pursuant to separate written contractual arrangements with such persons or
        entities, which can be sold without exceeding the Maximum Number of Securities.

      2.3.3 Piggyback Registration Withdrawal. Any Holder of Registrable Securities shall have the right to withdraw from a Piggyback Registration
          for any or no reason whatsoever upon written notification to the Company and the Underwriter or Underwriters (if any) of his, her or its intention to withdraw from such Piggyback Registration at least two (2) business days prior to the
          effectiveness of the Registration Statement filed with the Commission with respect to such Piggyback Registration (or in the case of an Underwritten Registration pursuant to Rule 415, at least five (5) business days prior to the time of pricing
          of the applicable offering). The Company (whether on its own good faith determination or as the result of a request for withdrawal by persons pursuant to separate written contractual obligations) may withdraw a Registration Statement filed with
          the Commission in connection with a Piggyback Registration at any time prior to the effectiveness of such Registration Statement. Notwithstanding anything to the contrary in this Agreement, the Company shall be responsible for the Registration
          Expenses incurred in connection with the Piggyback Registration prior to its withdrawal under this subsection 2.3.3.

       

      2.3.4 Unlimited Piggyback Registration Rights. For purposes of clarity, any Registration effected pursuant to Section 2.3 hereof shall
          not be counted as a Registration pursuant to a Demand Registration effected under Section 2.2 hereof.

       

      2.4 Restrictions on Registration Rights. If (A) during the period starting with the date sixty (60) days prior to the Company’s good faith
        estimate of the date of the filing of, and ending on a date one hundred and twenty (120) days after the effective date of, a Company initiated Registration and provided that the Company has delivered written notice to the Holders prior to receipt
        of a Demand Registration pursuant to subsection 2.2.1 and it continues to actively employ, in good faith, all reasonable efforts to cause the applicable Registration Statement to become effective; (B) the Holders have requested an
        Underwritten Registration and the Company and the Holders are unable to obtain the commitment of underwriters to firmly underwrite the offer; or (C) in the good faith judgment of the Board such Registration would be seriously detrimental to the
        Company and the Board concludes as a result that it is essential to defer the filing of such Registration Statement at such time, then in each case the Company shall furnish to such Holders a certificate signed by the Chairman of the Board, the
        Chief Executive Officer, the President, the Chief Financial Officer or the Secretary of the Company stating that in the good faith judgment of the Board it would be seriously detrimental to the Company for such Registration Statement to be filed in
        the near future and that it is therefore essential to defer the filing of such Registration Statement. In such event, the Company shall have the right to defer such filing for a period of not more than ninety (90) days; provided, however,
        that the Company shall not defer its obligation in this manner more than once in any 12-month period.

      3.1 General Procedures. If at any time on or after the Closing, the Company is required to effect the Registration of Registrable
          Securities, the Company shall use its commercially reasonable efforts to effect such Registration to permit the sale of such Registrable Securities in accordance with the intended plan of distribution thereof, and pursuant thereto the Company
          shall, as soon as reasonably practicable:

       

      3.1.1 prepare and file with the Commission as soon as practicable a Registration Statement with respect to such Registrable Securities and use its commercially reasonable efforts to cause such Registration Statement to become
          effective and remain effective until all Registrable Securities covered by such Registration Statement have been sold or otherwise cease to be Registrable Securities;

       

      3.1.2 prepare and file with the Commission such
          amendments and post-effective amendments to the Registration Statement, and such supplements to the Prospectus, as may be reasonably requested by a majority-in-interest of the Holders with Registrable Securities registered on such Registration
          Statement or any Underwriter of Registrable Securities or as may be required by the rules, regulations or instructions applicable to the registration form used by the Company or by the Securities Act or rules and regulations thereunder to keep
          the Registration Statement effective until all Registrable Securities covered by such Registration Statement are sold in accordance with the intended plan of distribution set forth in such Registration Statement or supplement to the Prospectus or otherwise cease to be Registrable Securities;

       

      3.1.3 prior to filing a Registration Statement or Prospectus, or any amendment or supplement thereto (except for supplements containing Exchange Act
        reports of the Company filed with respect to a Registration Statement or Prospectus for which forward incorporation by reference is unavailable), furnish without charge to the Underwriters, if any, and the Holders of Registrable Securities included
        in such Registration, and such Holders’ 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 the Underwriters and the Holders of Registrable Securities included in such Registration
        or the legal counsel for any such Holders may request in order to facilitate the disposition of the Registrable Securities owned by such Holders;

       

      3.1.4 prior to any public offering of Registrable Securities, use its best 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 the Holders of Registrable Securities included in such Registration Statement (in light of their intended plan of distribution) may
        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 Company and do any and all other acts and things that may be necessary or advisable to enable the Holders of Registrable Securities included in such Registration Statement to consummate the disposition of such Registrable
        Securities in such jurisdictions; provided, however, that the Company shall not be required to qualify generally to do business in any jurisdiction where it would not otherwise be required to qualify or take any action to which it
        would be subject to general service of process or taxation in any such jurisdiction where it is not then otherwise so subject;

       

      3.1.5 cause all such Registrable Securities to be listed on each securities exchange or automated quotation system on which similar securities
        issued by the Company are then listed;

       

      
        12

        
          


      

      3.1.6 provide a transfer agent or warrant agent, as applicable, and registrar for all such Registrable Securities no later than the effective date
        of such Registration Statement;

       

      3.1.7 advise each seller of such Registrable Securities, promptly after it shall receive notice or obtain knowledge thereof, of the issuance of any
        stop order by the Commission suspending the effectiveness of such Registration Statement or the initiation or threatening of any proceeding for such purpose and promptly use its reasonable best efforts to prevent the issuance of any stop order or
        to obtain its withdrawal if such stop order should be issued;

       

      3.1.8 at least five (5) days prior to the filing of any Registration Statement or Prospectus or any amendment or supplement to such Registration
        Statement or Prospectus (except for supplements containing Exchange Act reports of the Company filed with respect to a Registration Statement or Prospectus for which forward incorporation by reference is unavailable), furnish a copy thereof to each
        seller of such Registrable Securities or its counsel;

       

      3.1.9 notify the Holders at any time when a Prospectus relating to such Registration Statement is required to be delivered under the Securities Act, of the happening of any event as a result of which the Prospectus included in
          such Registration Statement, as then in effect, includes a Misstatement, and then to correct such Misstatement as set forth in Section 3.5 hereof;

       

      3.1.10 permit a representative of the Holders (such representative to be selected by a majority-in-interest of the Holders with Registrable Securities to be registered on the Registration
            Statement), the Underwriters, if any, and any attorney or accountant retained by such Holders or Underwriter to participate, at each such person’s own expense, in the preparation of the Registration Statement, and cause the Company’s
          officers, directors and employees to supply all information reasonably requested by any such representative, Underwriter, attorney or accountant in connection with the Registration; provided, however, that such representative or
          Underwriter enter into a confidentiality agreement, in form and substance reasonably satisfactory to the Company, prior to the release or disclosure of any such information;

       

      3.1.11 obtain a “comfort” letter from the Company’s independent registered public accountants in the event of an Underwritten Registration, in customary form and covering such matters of the type customarily covered by
          “comfort” letters as the managing Underwriter may reasonably request, and reasonably satisfactory to a majority-in-interest of the participating Holders;

       

      3.1.12 on the date the Registrable Securities are delivered for sale pursuant to such Registration, obtain an opinion, dated such date, of counsel representing the Company for the purposes of such Registration, addressed to
          the Holders, the placement agent or sales agent, if any, and the Underwriters, if any, covering such legal matters with respect to the Registration in respect of which such opinion is being given as the Holders, placement agent, sales agent, or
          Underwriter may reasonably request and as are customarily included in such opinions and negative assurance letters, and reasonably satisfactory to a majority-in-interest of the participating Holders;

       

      3.1.13 in the event of any Underwritten Offering, enter into and perform its obligations under an underwriting agreement, in usual and customary form, with the managing Underwriter of such offering;

       

      3.1.14 make available to its security holders, as soon as reasonably practicable, an earnings statement covering the period of at least twelve (12) months beginning with the first day of the Company’s first full calendar
          quarter after the effective date of the Registration Statement which satisfies the provisions of Section 11(a) of the Securities Act and Rule 158 thereunder (or any successor rule promulgated thereafter by the Commission); provided that the
          Company will be deemed to have satisfied such requirement to the extent such information is filed on EDGAR or any successor system;

       

      
        13

        
          


      

      3.1.15 in connection with any Shelf Underwritten Offering pursuant to Section 2.1.3 or any Underwritten Offering pursuant to Section 2.2.3, if such Shelf Underwritten Offering or Underwritten Offering involves the sale of
          Registrable Securities for gross proceeds in excess of $10,000,000, use its reasonable efforts to make available senior executives of the Company to participate in customary “road show” presentations that may be reasonably requested by the
          Underwriter in such Shelf Underwritten Offering or Underwritten Offering, as the case may be; and

       

      3.1.16 otherwise, in good faith, cooperate reasonably with, and take such customary actions as may reasonably be requested by the Holders, in connection with such Registration.

       

      3.2 Registration Expenses. The Registration Expenses of all Registrations shall be borne by the Company. It is acknowledged by the Holders
          that the Holders shall bear all incremental selling expenses relating to the sale of Registrable Securities, such as Underwriters’ commissions and discounts, brokerage fees, Underwriter marketing costs and, other than as set forth in the
          definition of “Registration Expenses,” all fees and expenses of any legal counsel representing the Holders.

       

      3.3 Holder Information Required for Participation in Registrations. At least ten (10) business days prior to the first anticipated filing
          date of a Registration Statement, the Company shall use its commercially reasonable efforts to notify each Holder in writing (which may be by email) of the information reasonably necessary about the Holder to include such Holder’s Registrable
          Securities in such Registration Statement. At least three (3) business days prior to the anticipated filing date of any post-effective amendment of a Registration Statement (including pursuant to subsection 2.1.2), the Company shall use
          its commercially reasonable efforts to notify each Holder of Registrable Securities included in such Registration Statement in writing (which may be by email) of the information reasonably necessary about the Holder to keep such Holder’s
          Registrable Securities in such Registration Statement. Notwithstanding anything else in this Agreement, the Company shall not be obligated to include or keep a Holder’s Registrable Securities in a Registration Statement to the extent the Company
          has not received such information, and received any other reasonably requested agreements or certificates, on or prior to the fifth (5th) business day prior to the first anticipated filing date of a Registration Statement or the second
          (2nd) business day prior to the anticipated filing date of any post-effective amendment of a Registration Statement, as applicable.

       

      3.4 Requirements for Participation in Underwritten Offerings. No person may participate in any Underwritten Offering for equity securities
          of the Company pursuant to a Registration initiated by the Company hereunder unless such person (i) agrees to sell such person’s securities on the basis provided in any underwriting arrangements approved by the Company and (ii) completes and
          executes all customary questionnaires, powers of attorney, indemnities, lock-up agreements, underwriting agreements and other customary documents as may be reasonably required under the terms of such underwriting arrangements.

       

      
        14

        
          


      

      3.5 Suspension of Sales; Adverse Disclosure. Upon receipt of written notice from the Company that a Registration Statement or Prospectus
        contains a Misstatement, each of the Holders shall forthwith discontinue disposition of Registrable Securities until such Holder has received copies of a supplemented or amended Prospectus correcting the Misstatement (it being understood that the
        Company hereby covenants to prepare and file such supplement or amendment as soon as practicable after the time of such notice), or until it is advised in writing by the Company that the use of the Prospectus may be resumed. If the filing, initial effectiveness or continued use of a Registration Statement in respect of any Registration at any time would require the Company to make an Adverse Disclosure or would require the inclusion in such
          Registration Statement of financial statements that are unavailable to the Company for reasons beyond the Company’s control, the Company may, upon giving prompt written notice of such action to the Holders, delay the filing or initial
          effectiveness of, or suspend use of, such Registration Statement for the shortest period of time, but in no event more than forty-five (45) days, determined in good faith by the Company to be necessary for such purpose. In the event the Company
          exercises its rights under the preceding sentence, the Holders agree to suspend, immediately upon their receipt of the notice referred to above, their use of the Prospectus relating to any Registration in connection with any sale or offer to sell
          Registrable Securities. The Company shall immediately notify the Holders of the expiration of any period during which it exercised its rights under this Section 3.5.

       

      3.6 Reporting Obligations. As long as any Holder shall own Registrable Securities, the Company, 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 Company after the date hereof pursuant to Sections 13(a) or 15(d)
        of the Exchange Act. The Company further covenants that it shall take such further action as any Holder may reasonably request, all to the extent required from time to time to enable such Holder to sell shares of the Common Stock held by such
        Holder without registration under the Securities Act within the limitation of the exemptions provided by Rule 144 promulgated under the Securities Act (or any successor rule promulgated thereafter by the Commission), including providing any legal
        opinions, it being acknowledged by the Holders that the securities of the Company will not be eligible for resale pursuant to Rule 144 promulgated under the Securities Act, until, among other requirements, at least one year has elapsed from the
        time that the Company has filed current Form 10 information with the Commission reflecting its status as an entity that is not a shell company. Upon the request of any Holder, the Company shall deliver to such Holder a written certification of a
        duly authorized officer as to whether it has complied with such requirements.

       

      3.7 Lock-up Restrictions.

       

      
        15

        
          


      

      3.7.1 During the Sponsor Shares Lock-up Period, none of the Sponsor Group Holders shall, and during the Accelus Shares Lock-up Period, none of the
        Accelus Holders shall without the prior written consent of the Company: offer, sell, contract to sell, pledge, grant any option to purchase, make any short sale or otherwise dispose of or distribute any shares of Common Stock or CHP Class B Common
        Stock that are subject to the applicable Lock-up Period or any securities convertible into, exercisable for, exchangeable for or that represent the right to receive Accelus Shares that are subject to the applicable Lock-up Period, whether now owned
        or hereinafter acquired, that is owned directly by such Holder (including securities held as a custodian) or with respect to which such Holder has beneficial ownership within the rules and regulations of the Commission (such securities that are
        subject to an applicable Lock-up Period, the “Restricted Securities”), other than any transfer to an affiliate of a Holder or to a Permitted Transferee, as applicable. The foregoing restriction is expressly agreed to preclude each Holder, as
        applicable, from engaging in any hedging or other transaction with respect to Restricted Securities which is designed to or which reasonably could be expected to lead to or result in a sale or disposition of the Restricted Securities even if such
        Restricted Securities would be disposed of by someone other than such Holder. Such prohibited hedging or other transactions include any short sale or any purchase, sale or grant of any right (including any put or call option) with respect to any of
        the Restricted Securities of the applicable Holder, or with respect to any security that includes, relates to, or derives any significant part of its value from such Restricted Securities. For the avoidance of doubt, the foregoing restriction shall
        not apply to transfers: (i) as a bona fide gift or charitable contribution, (ii) by will or intestate succession to a legal representative, heir, beneficiary or a member of the immediate family (as defined below) of any such Holder; (iii) to
        partners, members, beneficiaries (or the estates thereof) or stockholders of any such Holder, (iv) to any immediate family of any such Holder (“immediate family” shall mean any relationship by blood, marriage or adoption, not more remote than first
        cousin), (v) to any trust for the direct or indirect benefit of any such Holder or the immediate family of any such Holder, (vi) to any corporation, partnership, limited liability company, trust or other entity that controls, or is controlled by or
        is under common control with, any such Holder or the immediate family of any such Holder or is otherwise a direct or indirect affiliate, (vii) by operation of law, such as pursuant to a qualified domestic order, divorce settlement, divorce decree
        or separation agreement; or (viii) pursuant to a bona fide third party tender offer, merger, consolidation, equity purchase or other similar transaction or series of related transactions involving a change of control of the Company (including,
        without limitation, entering into any lock-up, voting or similar agreement pursuant to which any such Holder may agree to Restricted Shares in connection with such transaction or series of related transactions, or vote any Restricted Shares in
        favor of such transaction or series of related transactions); provided, that in the event such transaction or series of related transactions is not completed, the Restricted Shares shall remain subject to the restrictions contained in this
        Agreement; provided, that any such transfer pursuant to clauses (iii) through (vii) above shall not involve a disposition for value; provided, further, with respect to any such transfer pursuant to clauses (iii) through (viii)
        above, (1) each donee, trustee, distributee, or transferee, as the case may be, shall execute a joinder to this Agreement evidencing such donee’s, trustee’s, distributee’s, or transferee’s agreement to become a party hereto and be bound by and
        subject to the terms and provisions of this Agreement to the same effect, and (2) no filing by any party under the Exchange Act or other public announcement shall be made (including voluntarily) in connection with such transfer.

       

      3.7.2 The restrictions of subsection 3.7.1 shall not apply to: (i) the exercise (including by net or cashless exercise) of stock options
        granted pursuant to the Company’s equity incentive plans or warrants or any other securities existing as of the date hereof, which securities are convertible into or exchangeable or exercisable for Accelus Shares; provided, that such restrictions
        shall apply to any shares of Accelus Shares issued upon such exercise, exchange or conversion; (ii) the transfer or surrender to the Company of any Accelus Shares to cover tax withholdings upon a vesting event or settlement, as applicable, of any
        equity award under any of the Company’s equity incentive plans; provided, that the underlying shares of Accelus Shares shall continue to be subject to the restrictions set forth in subsection 3.7.1; (iii) the transfer of any Accelus Shares
        purchased by any such Holder on the open market following the date hereof; (iv) transfer of Accelus Shares to the Company pursuant to any contractual arrangement that provides the Company with an option to repurchase such Accelus Shares in
        connection with the termination of any such Holder’s employment with the Company, as applicable; and (v) the establishment of any contract, instruction or plan (a “Plan”), if permitted by the Company (such permission not to be unreasonably
        withheld, conditioned, delayed or applied asymmetrically to the undersigned as compared to any other employee of the Company), that satisfies all of the applicable requirements of Rule 10b5-1(c)(1)(i)(B) under the Exchange Act; provided that
        the securities subject to the Plan may not be sold until the end of the applicable Lock-Up Period (except to the extent otherwise allowed hereunder).

      3.7.3 Each Holder hereby represents and warrants that it now has and, except as contemplated by this subsection 3.7.2 for the duration of the applicable Lock-up Period, will have good and marketable title to its
          Restricted Securities, free and clear of all liens, encumbrances, and claims that could impact the ability of such Holder to comply with the foregoing restrictions. Each Holder agrees and consents to the entry of stop transfer instructions with
          the Company’s transfer agent and registrar against the transfer of any Restricted Securities during the applicable Lock-up Period.

       

      ARTICLE IV

      INDEMNIFICATION AND CONTRIBUTION

       

      4.1 Indemnification.

       

      4.1.1 The Company agrees to indemnify, to the extent permitted by law, each Holder of Registrable Securities, its officers and directors and agents and each person who controls such Holder (within the meaning of the Securities
          Act) against all losses, claims, damages, liabilities and expenses (including, without limitation, reasonable attorneys’ fees) resulting from any untrue or alleged untrue statement of material fact contained in any Registration Statement,
          Prospectus or preliminary Prospectus or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as
          the same are caused by or contained in any information or affidavit so furnished in writing to the Company by such Holder expressly for use therein.

       

      4.1.2 In connection with any Registration Statement in which a Holder of Registrable Securities is participating, such Holder shall furnish to the Company in writing such information and affidavits, with respect to such
          Holder, as the Company reasonably requests for use in connection with any such Registration Statement or Prospectus and, to the extent permitted by law, shall indemnify the Company, its directors and officers and agents and each person who
          controls the Company (within the meaning of the Securities Act) against all losses, claims, damages, liabilities and expenses (including, without limitation’ reasonable attorneys’ fees) resulting from any untrue or alleged untrue statement of
          material fact contained in any Registration Statement, Prospectus or preliminary Prospectus or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated therein or necessary to make
          the statements therein not misleading, but only to the extent that such untrue statement or omission is contained in any information or affidavit so furnished in writing by such Holder expressly for use therein; provided, however,
          that the obligation to indemnify shall be several, not joint and several, among such Holders of Registrable Securities, and the liability of each such Holder of Registrable Securities shall be in proportion to and limited to the net proceeds
          received by such Holder from the sale of Registrable Securities pursuant to such Registration Statement. The Holders of Registrable Securities shall indemnify the Underwriters, their officers, directors and each person who controls such
          Underwriters (within the meaning of the Securities Act) to the same extent as provided in the foregoing with respect to indemnification of the Company.

       

      
        17

        
          


      

      4.1.3 Any person entitled to indemnification herein shall (i) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification (provided that the failure to give prompt notice
          shall not impair any person’s right to indemnification hereunder to the extent such failure has not materially prejudiced the indemnifying party) and (ii) unless in such indemnified party’s reasonable judgment a conflict of interest between such
          indemnified and indemnifying parties may exist with respect to such claim, permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party. If such defense is assumed, the
          indemnifying party shall not be subject to any liability for any settlement made by the indemnified party without its consent (but such consent shall not be unreasonably withheld). An indemnifying party who is not entitled to, or elects not to,
          assume the defense of a claim shall not be obligated to pay the fees and expenses of more than one counsel for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of any indemnified
          party a conflict of interest may exist between such indemnified party and any other of such indemnified parties with respect to such claim. No indemnifying party shall, without the consent of the indemnified party, consent to the entry of any
          judgment or enter into any settlement which cannot be settled in all respects by the payment of money (and such money is so paid by the indemnifying party pursuant to the terms of such settlement) or which settlement does not include as an
          unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect to such claim or litigation.

       

      4.1.4 The indemnification provided for under this Agreement shall remain in full force and effect regardless of any investigation made by or on behalf of the indemnified party or any officer, director or controlling person of
          such indemnified party and shall survive the transfer of securities. The Company and each Holder of Registrable Securities participating in an offering also agrees to make such provisions as are reasonably requested by any indemnified party for
          contribution to such party in the event the Company’s or such Holder’s indemnification is unavailable for any reason.

       

      4.1.5 If the indemnification provided under Section 4.1 hereof from the indemnifying party is unavailable or insufficient to hold harmless
        an indemnified party in respect of any losses, claims, damages, liabilities and expenses referred to herein, then the indemnifying party, in lieu of indemnifying the indemnified party, shall contribute to the amount paid or payable by the
        indemnified party as a result of such losses, claims, damages, liabilities and expenses in such proportion as is appropriate to reflect the relative fault of the indemnifying party and the indemnified party, as well as any other relevant equitable
        considerations. The relative fault of the indemnifying party and indemnified party shall be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or
        omission or alleged omission to state a material fact, was made by, or relates to information supplied by, such indemnifying party or indemnified party, and the indemnifying party’s and indemnified party’s relative intent, knowledge, access to
        information and opportunity to correct or prevent such action and the benefits received by such indemnifying party or indemnified party; provided, however, that the liability of any Holder under this subsection 4.1.5 shall
        be limited to the amount of the net proceeds received by such Holder in such offering giving rise to such liability. The amount paid or payable by a party as a result of the losses or other liabilities referred to above shall be deemed to include,
        subject to the limitations set forth in subsections 4.1.1, 4.1.2 and 4.1.3 above, any legal or other fees, charges or expenses reasonably incurred by such party in connection with any investigation or proceeding. The parties
        hereto agree that it would not be just and equitable if contribution pursuant to this subsection 4.1.5 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 this subsection 4.1.5. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution pursuant to this subsection 4.1.5 from any person
        who was not guilty of such fraudulent misrepresentation.

      ARTICLE V

      NOMINATION RIGHTS

       

      5.1 Board Nomination Right.

       

      5.1.1  From
            the date hereof until the earlier of (i) three years from the Effective Date and (ii) the termination of this Agreement in accordance with Section 6.12, at every meeting of the Board, or a committee thereof, or action by written
            consent, at or by which directors of the Company are appointed by the Board or are nominated to stand for election and elected by stockholders of the Company, the Sponsor shall have the right to appoint or nominate for election to the Board, as
            applicable, one (1) individual, to serve as director of the Company (the individual appointed or nominated by the Sponsor for election to the Board pursuant to this subsection 5.1.1, a “Nominee”). As of the date hereof, the
            Nominee shall be Joe Swedish.

       

      5.1.2  The
            Company shall take all necessary actions within its control, including but not limited to calling a meeting of the Board or executing an action by unanimous written consent of the Board, such that, as of the date hereof, the Nominee shall
            either be elected by the Company’s stockholders at the meeting held to approve the Transactions or appointed to the Board as of the date hereof as a director of the Company.

       

      5.1.3   From
            and after the date hereof, the Company shall take all actions necessary (including, without limitation, calling special meetings of the Board and the stockholders of the Company and recommending, supporting and soliciting proxies) to ensure
            that: (i) the Nominee is included in the Board’s slate of nominees to the stockholders of the Company for the election of directors of the Company and recommended by the Board at any meeting of stockholders called for the purpose of electing
            directors of the Company; and (ii) the Nominee, if up for election, is included in the proxy statement prepared by management of the Company in connection with the Company’s solicitation of proxies or consents in favor of the foregoing for
            every meeting of the stockholders of the Company called with respect to the election of members of the Board, and at every adjournment or postponement thereof, and on every action or approval by written resolution of the stockholders of the
            Company or the Board with respect to the election of directors of the Company.

       

      5.1.4  If
            the Nominee ceases to serve for any reason, the Sponsor shall be entitled to designate and appoint or nominate such person’s successor in accordance with this Agreement and the Board shall promptly fill the vacancy with such successor Nominee;
            provided, that such successor shall be reasonably acceptable to the Company.

       

      
        19

        
          


      

      5.1.5  The
            Company shall indemnify the Nominee on the same basis as all other members of the Board and pursuant to an indemnity agreement with terms that are no less favorable to the Nominee than the indemnity agreements entered into between the Company
            and its other directors.

       

      5.1.6  The
            Nominee shall be entitled to compensation (including equity awards) that is consistent with the compensation received by other non-employee directors of the Company. In addition, the Company shall pay the reasonable, documented, out-of-pocket
            expenses incurred by the Nominee in connection with his or her services provided to or on behalf of the Company and its subsidiaries, including attending Board and committee meetings or events attended on behalf of the Company or at the
            Company’s request.

       

      5.1.7  Notwithstanding
            the provisions of this Section 5.1, the Sponsor shall not be entitled to designate a person as a nominee to the Board upon a written determination by the Board or relevant committee thereof that the person would not be qualified under
            any applicable law, rule or regulation to serve as a director of the Company. In such an event, the Sponsor shall be entitled to select a person as a replacement Nominee and the Company shall take all necessary actions within its control to
            cause that person to be nominated as a Nominee, including, without limitation, taking such necessary actions to cause that person to be nominated as a Nominee at the same meeting (or, if permitted, pursuant to the same action by written consent
            of the stockholders) as the initial person was to be nominated.

       

      ARTICLE VI

        20

        
          


      

      6.2.1 This Agreement and the rights, duties and obligations of the Company and the Holders, as the case may be, hereunder may not be assigned or delegated by the Company or the Holders, as the case may be, in whole or in part,
          except in connection with a transfer of Registrable Securities by such Holder to a Permitted Transferee but only if such Permitted Transferee agrees to become bound by the terms and restrictions set forth in this Agreement.

       

      6.2.2 Prior to the expiration of the Sponsor Shares Lock-up Period or Accelus Shares Lock-up Period, as the case may be, no Holder may assign or delegate such Holder’s rights, duties or obligations under this Agreement, in
          whole or in part, except in connection with a transfer of Registrable Securities by such Holder to a Permitted Transferee but only if such Permitted Transferee agrees to become bound by the transfer restrictions set forth in this Agreement,
          including the lock up restrictions applicable to the transferor, or any other applicable agreements between the Company and such Holder.

       

      6.2.3 This Agreement and the provisions hereof shall be binding upon and shall inure to the benefit of each of the parties and its successors and the permitted assigns of the Holders, which shall include Permitted Transferees.

       

      6.2.4 This Agreement shall not confer any rights or benefits on any persons that are not parties hereto, other than as expressly set forth in this Agreement and Section 6.2 hereof.

       

      6.2.5 No assignment by any party hereto of such party’s rights, duties and obligations hereunder shall be binding upon or obligate the Company unless and until the Company shall have received (i) written notice of such
          assignment as provided in Section 6.1 hereof and (ii) the written agreement of the assignee, in a form reasonably satisfactory to the Company, 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). Any transfer or assignment made other than as provided in this Section 6.2 shall be null and void.

       

      5.3 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.

       

      6.4 Counterparts. This Agreement may be executed in multiple counterparts (including facsimile or PDF counterparts), each of which shall be
          deemed an original, and all of which together shall constitute the same instrument, but only one of which need be produced.

       

      6.5 Governing Law; Venue. NOTWITHSTANDING THE PLACE WHERE THIS AGREEMENT MAY BE EXECUTED BY ANY OF THE PARTIES HERETO, THE PARTIES EXPRESSLY
          AGREE THAT (I) THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED UNDER THE LAWS OF THE STATE OF NEW YORK, INCLUDING, WITHOUT LIMITATION, SECTIONS 5-1401 AND 5-1402 OF THE NEW YORK GENERAL OBLIGATIONS LAW AND NEW YORK CIVIL PRACTICE LAWS AND RULES
          327(B), AS APPLIED TO AGREEMENTS AMONG NEW YORK RESIDENTS ENTERED INTO AND TO BE PERFORMED ENTIRELY WITHIN NEW YORK, WITHOUT REGARD TO THE CONFLICT OF LAW PROVISIONS OF SUCH JURISDICTION, AND (II) THE VENUE FOR ANY ACTION TAKEN WITH RESPECT TO
          THIS AGREEMENT SHALL BE ANY STATE OR FEDERAL COURT IN NEW YORK COUNTY IN THE STATE OF NEW YORK.

       

      
        21

        
          


      

      6.6 Entire Agreement. This Agreement (including all agreements entered into pursuant hereto and all certificates and instruments delivered
          pursuant hereto and thereto) constitute the entire agreement of the parties with respect to the subject matter hereof and supersede all prior and contemporaneous agreements, representations, understandings, negotiations and discussions between
          the parties, whether oral or written.

       

      6.7 Amendments and Modifications. Upon the written consent of the Company and the Holders of at least a majority-in-interest of the
          Registrable Securities at the time in question (including the Holders of a majority-in-interest of the Sponsor Shares and the Holders of a majority-in-interest of the Accelus Shares), compliance with any of the provisions, covenants and
          conditions set forth in this Agreement may be waived, or any of such provisions, covenants or conditions may be amended or modified; provided, however, that notwithstanding the foregoing, any amendment hereto or waiver hereof that
          adversely affects any Holder(s), solely in its capacity as a holder of the shares of capital stock of the Company, in a manner that is materially different from other Holders (in such capacity) shall require the consent of the Holder(s) so
          affected. No course of dealing between any Holder or the Company and any other party hereto or any failure or delay on the part of a Holder or the Company in exercising any rights or remedies under this Agreement shall operate as a waiver of any
          rights or remedies of any Holder or the Company. No single or partial exercise of any rights or remedies under this Agreement by a party shall operate as a waiver or preclude the exercise of any other rights or remedies hereunder or thereunder by
          such party. Any waiver, amendment or modification effected in accordance with this Section 6.7 shall be binding on all parties hereto, regardless of whether any such party has consented thereto.

       

      6.8 Titles and Headings. Titles and headings of sections of this Agreement are for convenience only and shall not affect the construction of
          any provision of this Agreement.

       

      6.9 Waivers and Extensions. Any party to this Agreement may waive any right, breach or default which such party has the right to waive,
          provided that such waiver will not be effective against the waiving party unless it is in writing, is signed by such party, and specifically refers to this Agreement. Waivers may be made in advance or after the right waived has arisen or the
          breach or default waived has occurred. Any waiver may be conditional. No waiver of any breach of any agreement or provision herein contained shall be deemed a waiver of any preceding or succeeding breach thereof nor of any other agreement or
          provision herein contained. No waiver or extension of time for performance of any obligations or acts shall be deemed a waiver or extension of the time for performance of any other obligations or acts.

       

      6.10 Remedies Cumulative. In the event that the Company fails to observe or perform any covenant or agreement to be observed or performed
          under this Agreement, the Holders 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.

       

      
        22

        
          


      

      6.11 Other Registration Rights. The Company represents and warrants that no person, other than the Holders with respect to Registrable
          Securities has any right to require the Company to register any securities of the Company for sale or to include such securities of the Company in any Registration filed by the Company for the sale of securities for its own account or for the
          account of any other person. Further, the Company represents and warrants that this Agreement supersedes any other registration rights agreement or agreement with similar terms and conditions and in the event of a conflict between any such
          agreement or agreements and this Agreement, the terms of this Agreement shall prevail.

       

      6.12 Term. This Agreement shall terminate upon the earlier of (i) the tenth anniversary of the date of this Agreement or (ii) the date as of
          which (A) all of the Registrable Securities have been sold pursuant to a Registration Statement (but in no event prior to the applicable period referred to in Section 4(a)(3) of the Securities Act and Rule 174 thereunder) or (B) the Holders of
          all Registrable Securities are permitted to sell the Registrable Securities without registration pursuant to Rule 144 promulgated under the Securities Act (but with no volume or manner of sale restrictions or limitations). The provisions of Section
            3.6 and Article IV shall survive any termination.
