At any time and from time to time, any of (i) Sponsor Holder or (ii) the holders of at least 20% in interest of the then-outstanding number of Registrable Securities (together with the Sponsor Holder, the “Demanding Holders”) may make a written demand for registration under the Securities Act of all or part of their Registrable Securities, as the case may be (a “Demand Registration”). Any demand for a Demand Registration shall specify the number of shares of Registrable Securities proposed to be sold and the intended method(s) of distribution thereof. The Company will notify all holders of Registrable Securities of the demand within five (5) days after the Company’s receipt of any such demand, and each holder of Registrable Securities who wishes to include all or a portion of such holder’s Registrable Securities in the Demand Registration shall so notify the Company within fifteen (15) days after the receipt by the holder of the notice from the Company. 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 Company shall not be obligated to effect more than one (1) Demand Registration for the Sponsor Holder and two (2) Demand Registrations for other holders of Registrable Securities under this Section 2.1.1.
​
2.1.2        Effective Registration. A registration will not count as a Demand Registration until the Registration Statement filed with the Commission with respect to such Demand Registration has been declared effective and the Company has complied with all of 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 Commission 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will be deemed not to have been declared effective, unless and until (i) such stop order or injunction is removed, rescinded or otherwise terminated, and (ii) a majority-in-interest of the Demanding Holders that have Registrable Securities included in such Demand Registration thereafter elect to continue the offering; provided, further, that the Company 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 such holders so advise the Company 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 holder to include its Registrable Securities in such registration shall be conditioned
​

US-DOCS\123786340.7

​

upon such holder’s participation in such underwriting and the inclusion of such holder’s Registrable Securities in the underwriting to the extent provided herein. All Demanding Holders proposing to distribute their Registrable Securities through such underwriting shall enter into an underwriting agreement in customary form with the Underwriter or Underwriters selected for such underwriting by a majority-in-interest of the holders 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 advises the Company and the Demanding Holders in writing that the dollar amount or number of shares of Registrable Securities which the Demanding Holders desire to sell, taken together with all other shares of Common Stock or other securities which the Company desires to sell and the shares of Common Stock, if any, as to which registration has been requested pursuant to written contractual piggy-back registration rights held by other shareholders of the Company 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 shares, as applicable, the “Maximum Number of Shares”), then the Company shall include in such registration: (i) first, the Registrable Securities as to which Demand Registration has been requested by the applicable Demanding Holders (pro rata in accordance with the number of shares that each such Person has requested be included in such registration, regardless of the number of shares held by each such Person (such proportion is referred to herein as “Pro Rata”)) that can be sold without exceeding the Maximum Number of Shares; (ii) second, to the extent that the Maximum Number of Shares has not been reached under the foregoing clause (i), the shares of Common Stock or other securities that the Company desires to sell that can be sold without exceeding the Maximum Number of Shares; and (iii) third, to the extent that the Maximum Number of Shares has not been reached under the foregoing clauses (i) and (ii), the shares of Common Stock or other securities for the account of other Persons that the Company is obligated to register pursuant to written contractual arrangements with such Persons and that can be sold without exceeding the Maximum Number of Shares.
​
2.1.5        Withdrawal. If a majority-in-interest of the Demanding Holders that have Registrable Securities included in the Demand Registration disapprove of the terms of any underwriting 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 Company and the Underwriter or Underwriters of their request to withdraw prior to the effectiveness of the Registration Statement filed with the Commission with respect to such Demand Registration. If the majority-in-interest of the Demanding Holders that have Registrable Securities included in a Demand Registration withdraws from a proposed offering relating to such Demand Registration, then such registration shall not count as a Demand Registration provided for in Section 2.1.
​
2.1.6       Shelf Registration. The Company shall file within 45 days of the closing of the Business Combination, and use commercially reasonable efforts to cause to be declared effective as soon as practicable thereafter, a Registration Statement for a shelf registration on Form S-1 (the “Form S-1 Shelf”) or, if the Company is eligible to use a Registration Statement on Form S-3, a shelf registration on Form S-3 (the “Form S-3 Shelf” and together with the Form S-1 Shelf, each a “Shelf”), in each case, covering the resale of all the Registrable Securities (determined as of two business days prior to such filing) on a delayed or continuous basis. Such Shelf shall provide for the resale of the Registrable Securities included therein pursuant to any method or combination of methods legally available to, and requested by, any holder named therein. The Company shall maintain a Shelf in accordance with the terms hereof, and shall prepare and file with the Commission such amendments, including post-effective amendments, and supplements as may be necessary to keep a Shelf continuously effective, available for use and in compliance with the provisions of the Securities Act until such time as there are no longer any Registrable Securities. In the event the Company files a Form S-1 Shelf, the Company shall use its commercially reasonable efforts to convert the Form S-1 Shelf (and any subsequent Shelf) to a Form S-3 Shelf as soon as practicable after the Company is eligible to use Form S-3. Notwithstanding anything to the contrary herein, to the extent there is an active Shelf under this Section 2.1.6 covering an Investor’s or Investors’ Registrable Securities, and such Investor or Investors qualify as Demanding Holders pursuant to Section 2.1.1 and wish to request an underwritten offering from such Shelf, such underwritten offering shall follow the procedures of Section 2.1 (including Section 2.1.3 and Section 2.1.4) but such underwritten offering shall be made from the Shelf and shall count against the number of long form Demand Registrations that may be made pursuant to Section 2.1.1. The Company shall have the right to remove any persons no longer holding Registrable Securities from the Shelf or any other shelf registration statement by means of a post-effective amendment.

If at any time 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, by the Company for its own account or for shareholders of the Company for their account (or by the Company and by shareholders of the Company including, without limitation, pursuant to Section 2.1), other than a Registration Statement (i) filed in connection with any employee stock option or other benefit plan, (ii) for an exchange offer or offering of securities solely to the Company’s existing shareholders, (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 (x) give written notice of such proposed filing to the holders of Registrable Securities as soon as practicable but in no event less than ten (10) days before the anticipated filing date, which notice shall 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, of the offering, and (y) offer to the holders of Registrable Securities in such notice the opportunity to register the sale of such number of shares of Registrable Securities as such holders may request in writing within five (5) days following receipt of such notice (a “Piggy-Back Registration”). The Company shall cause such Registrable Securities to be included in such registration and shall use its best efforts to cause 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 Company and to permit the sale or other disposition of such Registrable Securities in accordance with the intended method(s) of distribution thereof.

​

​
2.2.3        Withdrawal. Any holder of Registrable Securities may elect to withdraw such holder’s request for inclusion of Registrable Securities in any Piggy-Back Registration by giving written notice to the Company of such request to withdraw prior to the effectiveness of the Registration Statement. The Company (whether on its own determination or as the result of a withdrawal by persons making a demand pursuant to written contractual obligations) may withdraw a Registration Statement at any time prior to the effectiveness of such Registration Statement. Notwithstanding any such withdrawal, the Company shall pay all expenses incurred by the holders of Registrable Securities in connection with such Piggy-Back Registration as provided in Section 3.3.

Upon receipt of any notice from the Company of the happening of any event of the kind described in Section 3.1.4(iv), or, in the case of a resale registration on Form S-3 pursuant to Section 2.3 hereof, upon any suspension by the Company, pursuant to a written insider trading compliance program adopted by the Company’s Board of Directors, of the ability of all “insiders” covered by such program to transact in the Company’s securities because of the existence of material non-public information, each holder of 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 holder receives the supplemented or amended prospectus contemplated by Section 3.1.4(iv) or the restriction on the ability of “insiders” to transact in the Company’s securities is removed, as applicable, and, if so directed by the Company, each such holder will deliver to the Company all copies, other than permanent file copies then in such holder’s possession, of the most recent prospectus covering such Registrable Securities at the time of receipt of such notice.

​
3.3              Registration Expenses. The Company shall bear all costs and expenses incurred in connection with any Demand Registration pursuant to Section 2.1, any Piggy-Back Registration pursuant to Section 2.2, and any registration on Form S-3 effected pursuant to Section 2.3, and all expenses incurred in performing or complying with its other obligations under this Agreement, whether or not the Registration Statement becomes effective, including, without limitation: (i) all registration and filing fees; (ii) fees and expenses of compliance with securities or “blue sky” laws (including fees and disbursements of counsel in connection with blue sky qualifications of the Registrable Securities); (iii) printing expenses; (iv) the Company’s internal expenses (including, without limitation, all salaries and expenses of its officers and employees); (v) the fees and expenses incurred in connection with the listing of the Registrable Securities as required by Section 3.1.11; (vi) Financial Industry Regulatory Authority fees; (vii) fees and disbursements of counsel for the Company and fees and expenses for independent certified public accountants retained by the Company (including the expenses or costs associated with the delivery of any opinions or comfort letters requested pursuant to Section 3.1.9); (viii) the reasonable fees and expenses of any special experts retained by the Company in connection with such registration and (ix) the reasonable fees and expenses of one legal counsel selected by the holders of a majority-in-interest of the Registrable Securities included in such registration. The Company shall have no obligation to pay any underwriting discounts or selling commissions attributable to the Registrable Securities being sold by the holders thereof, which underwriting discounts or selling commissions shall be borne by such holders. Additionally, in an underwritten offering, all selling shareholders and the Company shall bear the expenses of the Underwriter pro rata in proportion to the respective amount of shares each is selling in such offering.
​
3.4              Information. The holders of Registrable Securities shall provide such information as may reasonably be requested by the Company, or the managing Underwriter, if any, in connection with the preparation of any Registration Statement, including amendments and supplements thereto, in order to effect the registration of any Registrable Securities under the Securities Act pursuant to Section 2 and in connection with the Company’s obligation to comply with Federal and applicable state securities laws.
​
3.5              Market Stand-off. In connection with any underwritten offering pursuant to a Demand Registration, if requested by the managing Underwriter or Underwriters of such underwritten offering, each participating holder will agree that it shall not transfer any shares of Common Stock or other equity securities of the Company held as of the date of pricing of such underwritten offering (other than those included in such offering pursuant to this Agreement), without the prior written consent of the managing Underwriter or Underwriters, during the ninety (90)-day period beginning on the date of pricing of such underwritten offering or such shorter period during which the Company agrees not to conduct an underwritten primary offering of Common Stock, except in the event the managing Underwriter or Underwriters of such underwritten offering otherwise agree in writing. For the avoidance of doubt, this restriction shall not apply to any shares of Common Stock acquired in open market transactions following the date of pricing of such underwritten offering.
​
4.                  INDEMNIFICATION AND CONTRIBUTION.
​
4.1              Indemnification by the Company. The Company agrees to indemnify and hold harmless each Investor and each other holder of Registrable Securities, and each of their respective officers and directors and each Person, if any, who controls an Investor and each other holder of Registrable Securities (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 statement (or allegedly 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 Company of the Securities Act or any rule or regulation promulgated thereunder applicable to the Company and relating to action or inaction required of the Company in connection with any such registration; and the Company 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 Company 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 statement or allegedly untrue statement or omission or alleged omission made in such Registration Statement,
​

US-DOCS\123786340.7

​

preliminary prospectus, final prospectus, or summary prospectus, or any such amendment or supplement, in reliance upon and in conformity with information furnished to the Company, in writing, by such selling holder expressly for use therein. The Company also shall indemnify any Underwriter of the Registrable Securities and such Underwriter’s respective officers and directors and each Person who controls such Underwriter on substantially the same basis as that of the indemnification provided above in this Section 4.1.
​
4.2Indemnification by Holders of Registrable Securities. Each selling holder of 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 holder, indemnify and hold harmless the Company, 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 or allegedly 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 the 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 Company by such selling holder expressly for use therein, and shall reimburse the Company, its directors and officers, 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 holder’s indemnification obligations hereunder shall be several and not joint and shall be in proportion to and limited to the amount of any net proceeds actually received by such selling holder from the sale of the applicable Registrable Securities pursuant to the Registration Statement.
​
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. 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, 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
​

US-DOCS\123786340.7

​

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 or alleged untrue statement of a material fact or the omission or alleged 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 holder of 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 holder from the sale of Registrable Securities which gave rise to such contribution obligation. 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.
​
5.1              Rule 144. The Company covenants that it shall (i) make and keep public information available, as those terms are understood and defined in Rule 144, and (ii) 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 Investor holding Registrable Securities may reasonably request, all to the extent required from time to time to enable such Investor to sell Registrable Securities without registration under the Securities Act within the limitation of the exemptions provided by Rule 144 (or any similar or successor rule thereto). Upon the request of any Investor, the Company shall deliver to such Investor (i) a copy of the most recent periodic report of the Company and such other reports and documents so filed by the Company with the Commission (it being understood that the availability of such report on the Commission’s EDGAR system shall satisfy this requirement) and (ii) such other information as may be reasonably necessary to permit the Investor to sell its Registrable Securities pursuant to Rule 144 (or any similar or successor rule thereto) without registration.
​
6.                  MISCELLANEOUS.
​
6.1              Other Registration Rights. The Company represents and warrants that no person, other than the holders of the Registrable Securities and the holders of the PIPE Shares pursuant to the Subscription Agreements, has any right to require the Company to register any shares of the Company’s capital stock for sale or to include shares of the Company’s capital stock in any registration filed by the Company for the sale of shares of capital stock 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 (excluding the Subscription Agreements) and in the event of a conflict between any such agreement or agreements and this Agreement, the terms of this Agreement shall prevail.
​
6.2              Assignment; No Third Party Beneficiaries. This Agreement and the rights, duties and obligations of the Company hereunder may not be assigned or delegated by the Company in whole or in part. This Agreement and the rights, duties and obligations of the holders of Registrable Securities hereunder may be freely assigned or delegated by such holder of Registrable Securities in conjunction with and to the extent of any transfer of Registrable Securities by any such holder. This Agreement and the provisions hereof shall be binding upon and shall inure to the benefit of each of the parties hereto, to the permitted assigns of the Investors or holder of Registrable Securities or of any assignee of the Investors or holder of Registrable Securities. This Agreement is not intended to
​

US-DOCS\123786340.7

​

confer any rights or benefits on any Persons that are not party hereto other than as expressly set forth in Article 4 and this Section 6.2.
​
6.3              Notices. All notices, demands, requests, consents, approvals or other communications (collectively, “Notices”) required or permitted to be given hereunder or which are given with respect to this Agreement shall be in writing and shall be personally served, delivered by reputable air courier service with charges prepaid, or transmitted by hand delivery, facsimile or e-mail, addressed as set forth below, or to such other address as such party shall have specified most recently by written notice. Notice shall be deemed given on the date of service or transmission if personally served or transmitted by facsimile or e-mail; provided, that if such service or transmission is not on a business day or is after normal business hours, then such notice shall be deemed given on the next business day. Notice otherwise sent as provided herein shall be deemed given on the next business day following timely delivery of such notice to a reputable air courier service with an order for next-day delivery.

​
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.
​
6.5              Counterparts. This Agreement may be executed in multiple counterparts, each of which shall be deemed an original, and all of which taken together shall constitute one and the same instrument. The words “execution,” signed,” “signature,” and words of like import in this Agreement or in any other certificate, agreement or document related to this Agreement shall include images of manually executed signatures transmitted by facsimile or other electronic format (including, without limitation, “pdf”, “tif” or “jpg”) and other electronic signatures (including, without limitation, DocuSign and AdobeSign).  The use of electronic signatures and electronic records (including, without limitation, any contract or other record created, generated, sent, communicated, received, or stored by electronic means) shall be of the same legal effect, validity and enforceability as a manually executed signature or use of a paper-based record-keeping system to the fullest extent permitted by applicable law, including the Federal Electronic Signatures in Global and National Commerce Act, the New York State Electronic Signatures and Records Act and any other applicable law, including, without limitation, any state law based on the Uniform Electronic Transactions Act or the Uniform Commercial Code.
​
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
​

US-DOCS\123786340.7

​

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              Term. This Agreement shall terminate on the earlier of (i) with respect to any Investor, the date on which such Investor no longer holds any Registrable Securities and (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 any successor rule promulgated thereafter by the Commission)) or (B) the holders of all Registrable Securities are permitted to sell the Registrable Securities under Rule 144 (or any similar provision) under the Securities Act without limitation on the amount of securities sold or the manner of sale and without compliance with the current public reporting requirements set forth under Rule 144(i)(2). The provisions of Article IV and Article V shall survive any termination.
​
6.8             Modifications and Amendments. No amendment, modification or termination of this Agreement shall be binding upon the holders of the Registrable Securities unless executed in writing by the holders of a majority in interest of the Registrable Securities at the time in question.  Upon the written consent of the Company and the holders of a majority in interest of the Registrable Securities at the time in question, 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 one holder of Registrable Securities, solely in its capacity as a holder of the shares of capital stock of the Company, in a manner that is materially different from the other holders of Registrable Securities (in such capacity) shall require the consent of the holder so affected. No course of dealing between any holder of Registrable Securities or the Company and any other party hereto or any failure or delay on the part of a holder of Registrable Securities 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 of Registrable Securities 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.
​
6.9              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.
​
6.10          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.
​
6.11          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 Investor or any other holder of Registrable Securities 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.
​
6.12          Governing Law. This Agreement shall be governed by, interpreted under, and construed in accordance with the internal laws of the State of New York applicable to agreements made and to be performed within the State of New York, without giving effect to any choice-of-law provisions thereof that would compel the application of the substantive laws of any other jurisdiction.
​
6.13          Waiver of Trial by Jury. Each party hereby irrevocably and unconditionally waives the right to a trial by jury in any action, suit, counterclaim or other proceeding (whether based on contract, tort or
​

US-DOCS\123786340.7

​

otherwise) arising out of, connected with or relating to this Agreement, the transactions contemplated hereby, or the actions of the Investor in the negotiation, administration, performance or enforcement hereof.
​
6.14Holder Information. Each holder of Registrable Securities agrees, if requested in writing, to represent to the Company the total number of Registrable Securities held by such holder in order for the Company to make determinations hereunder.

Section 2.02Nomination Rights of Stockholders.  Notwithstanding anything to the contrary contained herein or in any other Transaction Document, each of the Stockholders and the Company agree (it being understood that such agreement is solely between the Company and each Stockholder, and not any other Stockholder) that, with respect to each subsequent election of Directors and subject to the rules and regulations of NASDAQ, from and after the Closing and until the first date on which a Stockholder (together with its Affiliates) Beneficially Owns less than 10.0% of the issued and outstanding Common Stock:
(a)such Stockholder shall be entitled to nominate one (1) Person for election as a Director (each such Director, a “Legacy Director”) at the applicable Company Stockholders Meeting by written notice to the Company given (i) in the case of an annual meeting of the stockholders of the Company, not less than ninety (90) days nor more than one hundred twenty (120) days prior to the one-year anniversary of the preceding year’s annual meeting (provided, however, that, if no annual meeting of the Company’s stockholders was held in the preceding year, not earlier than the close of business on the one hundred twentieth (120th) day prior to such annual meeting and not later than the close of business on the later of the ninetieth (90th) day prior to such annual meeting or, if later, the tenth (10th) day following the day on which public disclosure (as defined in the Bylaws) was first made by the Company; provided, further, that if the date of the annual meeting of the stockholders of the Company is more than thirty (30) days before or more than sixty (60) days after such anniversary date, not later than the ninetieth (90th) day prior to such annual meeting or, if later, the tenth (10th) day following the day on which public disclosure of the date of such annual meeting was first made by the Company) and (ii) in the case of a special meeting of the stockholders of the Company, not earlier than the one hundred twentieth (120th) day prior to such special meeting and not less than the later of ninety (90) days prior to such special

5

meeting or the tenth (10th) day following the day on which public disclosure of the date of such special meeting was first made by the Company, which such notice shall include all information relating to such Stockholder that is required to be disclosed in a proxy statement or other filings required to be made in connection with solicitations of proxies for election of directors in a contested election pursuant to Section 14(a) of the Exchange Act (including such Stockholder’s written consent to being named in the proxy statement and such nominee’s written consent to being named as a nominee and to serving as a director if elected); and
(b)The Company shall (i) include each Legacy Director as a nominee for election as a Director at the applicable Company Stockholders Meeting in its proxy solicitation materials (including any form of proxy it distributes), and (ii) unless the Board (or a committee thereof) reasonably determines in good faith, after receiving an opinion of the Company’s outside counsel, that doing so would cause it to violate its fiduciary duties to stockholders under Law, (A) recommend to the Company’s stockholders that such Legacy Director be elected as a Director at such Company Stockholders Meeting and (B) use reasonable best efforts to provide the highest level of support (including as to recommendation) as is used and/or provided for the election of the other Director nominees of the Company at such Company Stockholders Meeting.
For the avoidance of doubt, (i) each Stockholder’s right to nominate a Legacy Director under this Section 2.02 (A) shall not be transferable and (B) shall not be subject to any requirement that stockholders provide advance notice of, or comply with any other procedures governing, the nomination of individuals for election to the Board as provided in the Bylaws, (ii) such Stockholder shall no longer have a right to nominate a Legacy Director under this Section 2.02 from and after the first date on which such Stockholder (together with its Affiliates) Beneficially Owns less than 10.0% of the issued and outstanding Common Stock; and (iii) no Stockholder shall be required to comply with the provisions of Section 2.02(a) with respect to an election of Directors at any Company Stockholders Meeting if the Board or any committee thereof shall have nominated such Director for election as a Director without regard to the provisions of this Section 2.02.
Section 2.03Resignation of Designated Directors. On or promptly (but no later than three (3) Business Days) following the date that a Stockholder becomes actually aware that such Stockholder (together with its Affiliates) no longer Beneficially Owns at least 10.0% of the issued and outstanding Common Stock or has elected to withdraw from this Agreement pursuant to Section 4.04(d), the Nominating and Corporate Governance Committee of the Board may request that any Director designated or nominated by such Stockholder who is a member of the Board on such date tender such individual’s resignation as a Director, which resignation may be accepted or declined by the Board in its sole discretion.
Section 2.04Vacancy. Subject to Section 2.01(a) hereof with regard to LSAQ’s right to designate the LSAQ Director, in the event that a vacancy on the Board exists or is created at any time by the death, resignation, disqualification or removal of a member of the Initial Board prior to the due election and qualification of such member’s successor, such vacancy shall be filled pursuant to the Certificate of Incorporation; provided, however, that if such vacancy relates to a Legacy Director, the applicable Stockholder shall (until such time as such Stockholder and its Affiliates Beneficially Own less than 10.0% of the issued and outstanding Common Stock) be entitled to designate such Legacy Director’s successor.
Section 2.05Chairperson of the Board. Mr. Faulkner shall serve as the initial Chairperson of the Board, and any successor Chairperson of the Board shall be designated as provided in the Bylaws.
Section 2.06Classified Board. The Company represents and warrants that immediately prior to the execution and delivery hereof the Board is divided into three classes, with the Directors serving staggered three-year terms. The individual Directors comprising each class will be as determined by the Board.  Each Legacy 

6

Director nominated for election at the applicable Company Stockholders Meeting shall be nominated for, and, subject to Section 2.03, shall be entitled to serve, a three-year term or until such Legacy Director’s earlier death, resignation, disqualification or removal.
Section 2.07Insider Trading Policy. Immediately after the Closing, the Board shall adopt an insider trading policy containing terms and conditions typical for a public company similarly situated to the Company.
Section 2.08Indemnification and D&O Insurance. As promptly as reasonably practicable following the Closing, the Company shall enter into an indemnification agreement with each Director, each on substantially the same terms entered into with, and based on the same customary and reasonable form provided to, the other Directors. To the fullest extent permitted by applicable Law, the Company shall not amend, alter or repeal any right to indemnification, advancement of expenses or exculpation benefiting any Director nominated pursuant to this Agreement, as and to the extent consistent with applicable Law, contained in the Company’s Certificate of Incorporation or Bylaws (except to the extent such amendment or alteration permits the Company to provide broader rights to indemnification, advancement of expenses or exculpation). The Company shall (a) purchase directors’ and officers’ liability insurance in an amount determined by the Board to be reasonable and customary and (b) for so long as a Director nominated pursuant to this Article II serves as a Director of the Company, maintain such coverage with respect to such Director and shall take all actions necessary to extend such coverage for a period of not less than six years from any removal or resignation of such Director, in respect of any act or omission occurring at or prior to such event.
Section 2.09Reimbursement of Expenses. The Company shall reimburse the Directors for all reasonable and documented out-of-pocket expenses incurred in connection with their attendance at meetings of the Board and any committees thereof, including travel, lodging and meal expenses.
Section 2.10Restrictions on Other Agreements. No Party shall grant any proxy or enter into or agree to be bound by any voting trust, agreement or arrangement of any kind with any Person if and to the extent the terms thereof conflict with the provisions of this Agreement.

Neither the execution and delivery of this Agreement, nor the consummation of the transactions contemplated hereby, nor compliance with the terms hereof, will, (a) conflict with or violate any provision of the organizational documents of such Party or (b) violate, conflict with or result in a breach of, or constitute a default (with or without notice or lapse of time or both) under any provision of, any trust agreement, loan or credit agreement, note, bond, mortgage, indenture, lease or other agreement, instrument, permit, concession, franchise, license, judgment, order, notice, decree, statute, law, ordinance, rule or regulation applicable to such Party or to such Party’s property or assets, except, in the case of this clause (b), that would not reasonably be expected to impair, individually or in the aggregate, such Party’s ability to fulfill its obligations under this Agreement.

Section 4.04Amendment; Waiver.
(a)The terms and provisions of this Agreement may be modified or amended only with the written approval of the Company, LifeSci and each of the Stockholders entitled to designate a Director as of such time; provided, that any modification or amendment of (x) the last two sentences of Section 2.08 and (y) Section 4.01 to the extent that it relates to Section 2.08 shall, in each case, require the written approval of each Stockholder irrespective of whether it is entitled to designate a Director; provided further, that written approval of LifeSci shall only be required if the modification or amendment to this Agreement limits LifeSci’s right to designate the LSAQ Director.
(b)Except as expressly set forth in this Agreement, neither the failure nor delay on the part of any Party to exercise any right, remedy, power or privilege under this Agreement shall

10

operate as a waiver thereof, nor shall any single or partial exercise of any right, remedy, power or privilege preclude any other or further exercise of the same or of any other right, remedy, power or privilege, nor shall any waiver of any right, remedy, power or privilege with respect to any occurrence be construed as a waiver of such right, remedy, power or privilege with respect to any other occurrence.
(c)No Party shall be deemed to have waived any claim arising out of this Agreement, or any right, remedy, power or privilege under this Agreement, unless the waiver of such claim, right, remedy, power or privilege is expressly set forth in a written instrument duly executed and delivered on behalf of such Party, and any such waiver shall not be applicable or have any effect except in the specific instance in which it is given.

Section 4.05Further Assurances. To the fullest extent permitted by Law, the Stockholders agree to sign such further documents, cause such meetings to be held, resolutions passed and do and perform and cause to be done such further acts and things reasonably necessary in order to give full effect to this Agreement and every provision hereof. To the fullest extent permitted by Law, the Company shall not directly or indirectly take any action that is intended to, or would reasonably be expected to result in, the Stockholders being deprived of the rights contemplated by this Agreement.
Section 4.06Third Party Beneficiaries. The Parties hereby agree that their respective representations, warranties, covenants and agreements set forth in this Agreement are solely for the benefit of the other Parties on the terms and subject to the conditions set forth in this Agreement and are not for the benefit of any other Person who is not a party to this Agreement.

11

in this Agreement as characterizations of actual facts or circumstances as of the date of this Agreement or as of any other date.
Section 4.07Governing Law; Forum.
(a)This Agreement, and any claims or Proceedings arising out of this Agreement or the subject matter hereof (whether at law or equity, in contract or in tort or otherwise), shall be governed by and construed in accordance with the laws of the State of Delaware without regard to the conflict of law principles thereof (or any other jurisdiction) to the extent that such principles would direct a matter to another jurisdiction.
(b)Each of the Parties agrees that: (i) it shall bring any Proceeding in connection with, arising out of or otherwise relating to this Agreement, any agreement, certificate, instrument or other document delivered pursuant to this Agreement or the Transactions exclusively in the courts of the State of Delaware in the Court of Chancery of the State of Delaware, or (and only if) such court finds it lacks subject matter jurisdiction, the Superior Court of the State of Delaware (Complex Commercial Division); provided that if subject matter jurisdiction over the Proceeding is vested exclusively in the United States federal courts, then such Proceeding shall be heard in the United States District Court for the District of Delaware (the “Chosen Courts”); and (ii) solely in connection with such Proceedings, (A) it irrevocably and unconditionally submits to the exclusive jurisdiction of the Chosen Courts, (B) it waives any objection to the laying of venue in any Proceeding in the Chosen Courts, (C) it waives any objection that the Chosen Courts are an inconvenient forum or do not have jurisdiction over any Party, (D) mailing of process or other papers in connection with any such Proceeding in the manner provided in Section 4.03 or in such other manner as may be permitted by applicable Law shall be valid and sufficient service thereof and (E) it shall not assert as a defense, any matter or claim waived by the foregoing clauses (A) through (D) of this Section 4.07 or that any Governmental Order issued by the Chosen Courts may not be enforced in or by the Chosen Courts.
Section 4.08Waiver of Jury Trial. EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY BE IN CONNECTION WITH, ARISE OUT OF OR OTHERWISE RELATE TO THIS AGREEMENT OR OTHER DOCUMENT DELIVERED PURSUANT TO THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE EACH PARTY IRREVOCABLY AND UNCONDITIONALLY WAIVES TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY WITH RESPECT TO ANY PROCEEDING DIRECTLY OR INDIRECTLY, IN CONNECTION WITH, ARISING OUT OF OR OTHERWISE RELATING TO THIS AGREEMENT OR OTHER DOCUMENT DELIVERED PURSUANT TO THIS AGREEMENT. EACH PARTY HEREBY ACKNOWLEDGES AND CERTIFIES (a) THAT NO REPRESENTATIVE OF THE OTHER PARTIES HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTIES WOULD NOT, IN THE EVENT OF ANY ACTION OR PROCEEDING, SEEK TO ENFORCE THE FOREGOING WAIVER, (b) IT UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER, (c) IT MAKES THIS WAIVER VOLUNTARILY AND (iv) IT HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT AND THE TRANSACTIONS, BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS, ACKNOWLEDGMENTS AND CERTIFICATIONS CONTAINED IN THIS SECTION 4.08.
Section 4.09Equitable Remedies. Each of the Parties acknowledges and agrees that the rights and obligations of each Party to consummate the Transactions are special, unique and of extraordinary character and that if for any reason any of the provisions of this Agreement are not performed or complied with in accordance with their terms or are otherwise breached, immediate and irreparable harm or damage would be caused for which money damages would not be an adequate remedy.  Accordingly, each Party agrees that, in addition to any other 

12

available remedies a Party may have in equity or at law, each Party shall be entitled to equitable remedies against another Party for its breach or threatened breach of this Agreement, including to enforce specifically the terms and provisions of this Agreement or to obtain an injunction restraining any such breach or threatened breach of the provisions of this Agreement in the Chosen Courts, in each case, (a) without necessity of posting a bond or other form of security and (b) without proving the inadequacy of money damages or another any remedy at law. In the event that a Party seeks equitable remedies in any Proceeding (including to enforce the provisions of this Agreement or prevent breaches or threatened breaches of this Agreement), no Party shall raise any defense or objection, and each Party hereby waives any and all defenses and objections, to such equitable remedies on grounds that (i) money damages would be adequate or there is another adequate remedy at law or (ii) the Party seeking equitable remedies must either post a bond or other form of security and prove the inadequacy of money damages or another any remedy at law.
Section 4.10Entire Agreement; Successors and Assigns. This Agreement constitutes the entire agreement among the Parties and their Affiliates with respect to the subject matter hereof and thereof and supersede all prior and contemporaneous agreements, negotiations, understandings, and representations and warranties, whether oral or written, with respect to such matters.  This Agreement shall be binding upon and inure to the benefit of the Parties (and any of their respective successors and permitted assigns).  No Party shall be permitted to assign any of its rights or delegate any of its obligations under this Agreement, in whole or in part, by operation of Law or otherwise, without the prior written consent of the other Parties, and any attempted or purported assignment or delegation in violation of this Section 4.10 shall be null and void.
Section 4.11Severability. The provisions of this Agreement shall be deemed severable and the illegality, invalidity or unenforceability of any provision shall not affect the legality, validity or enforceability of the other provisions of this Agreement. If any provision of this Agreement, or the application of such provision to any Person or any circumstance, is illegal, invalid or unenforceable, (a) a suitable and equitable provision to be negotiated by the Parties, each acting reasonably and in good faith shall be substituted therefor in order to carry out, so far as may be legal, valid and enforceable, the intent and purpose of such legal, invalid or unenforceable provision, and (b) the remainder of this Agreement and the application of such provision to other Persons or circumstances shall not be affected by such illegality, invalidity or unenforceability, nor shall such illegality, invalidity or unenforceability affect the legality, validity or enforceability of such provision, or the application of such provision, in any other jurisdiction.
Section 4.12Headings. The descriptive headings contained in this Agreement are included for convenience of reference only and shall not affect in any way the meaning or interpretation of this Agreement.
Section 4.13Counterparts. This Agreement may be executed in any number of counterparts, each such counterpart being deemed to be an original instrument, and all such counterparts shall together constitute the same agreement. The exchange of copies of this Agreement and signature pages by email in .pdf or .tif format (and including, without limitation, any electronic signature complying with the U.S. ESIGN Act of 2000, e.g., www.docusign.com), or by any other electronic means intended to preserve the original graphic and pictorial appearance of a document, or by combination of such means, shall constitute effective execution and delivery of this Agreement as to the parties hereto and may be used in lieu of the original Agreement for all purposes. Such execution and delivery shall be considered valid, binding and effective for all purposes.

Any and all claims, demands, liabilities, obligations, debts, damages, losses, expenses, costs or Proceedings (whether in contract or in tort, in law or in equity, or granted by statute) that may be based upon, in respect of, arise under, out or by reason of, be connected with, or relate in any manner to this Agreement or the subject matter hereof (including the Transactions), any agreement, certificate, instrument or 

13

other document delivered pursuant to this Agreement or the subject matter thereof, or any negotiation, execution, or performance of any of the foregoing, shall be brought, raised or claimed only against the Persons that are expressly identified as “Parties” in the Preamble to this Agreement (the “Contracting Parties”).  No Nonparty Person shall have any responsibility, obligation or liability for any claims, demands, liabilities, obligations, debts, damages, losses, expenses, costs or Proceedings (whether in contract or in tort, in law or in equity, or granted by statute) arising under, out of, in connection with, or related in any manner to this Agreement or based on, in respect of, or by reason of this Agreement (including the Transactions) or its negotiation, execution, performance, or breach and, to the maximum extent permitted by Laws, each Contracting Party hereby irrevocably, unconditionally, completely and forever releases, discharges, ceases and waives all such claims, demands, liabilities, obligations, debts, damages, losses, expenses, costs or Proceedings (whether in contract or in tort, in law or in equity, or granted by statute) against any such Nonparty Persons.  Without limiting the foregoing, to the maximum extent permitted by Laws, (a) each Contracting Party hereby irrevocably, unconditionally, completely and forever releases, discharges, ceases and waives any and all claims, demands, liabilities, obligations, debts, damages, losses, expenses, costs or Proceedings (whether in contract or in tort, in law or in equity, or granted by statute) that may otherwise be available at law or in equity, or granted by statute, to avoid or disregard the entity form of a Contracting Party or otherwise impose liability of a Contracting Party on any Nonparty Person, whether granted by statute or based on theories of equity, agency, control, instrumentality, alter ego, domination, sham, single business enterprise, piercing the veil, unfairness, undercapitalization, or otherwise; and (b) each Contracting Party disclaims any reliance upon any Nonparty Person with respect to the performance of this Agreement or any representation or warranty made in, in connection with, or as an inducement to this Agreement. The “Nonparty Persons” means the Persons who are not Contracting Parties, and the term “Nonparty Persons” shall include, but not be limited to, all past, present or future stockholders, members, partners, other securityholders, controlling Persons, directors, managers, officers, employees, incorporator, Affiliates, agents, attorneys, advisors, other Representatives, lenders, capital providers, successors or permitted assigns of all Contracting Parties, all Affiliates of any Contracting Party or of all past, present or future stockholders, members, partners, other securityholders, controlling Persons, directors, managers, officers, employees, incorporator, Affiliates, agents, attorneys, advisors, other Representatives, lenders, capital providers, successors or permitted assigns of all of the foregoing.
