Statement or Prospectus or any amendment or supplement to such Registration Statement or Prospectus or any document that is to be incorporated by reference into such Registration Statement or Prospectus, 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 3.4 hereof; 
 3.1.10 permit a representative of the Holders (such representative to be selected by
a majority of the participating Holders), 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, that such
representatives or Underwriters 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 may be found 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 may be found 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 Underwriters 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); 

3.1.15 if the Registration involves the Registration of Registrable Securities involving gross proceeds in excess of $25,000,000, 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 any Underwritten Offering; 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 reasonable fees and expenses of any legal counsel representing the Holders. 

3.3 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. 
 3.4 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 it 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 supplemented or amended Prospectus 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 thirty (30) 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 3.4, and upon the expiration of such period the
Holders shall be entitled to resume the use of any such Prospectus in connection with any sale or offer to sell Registrable Securities. 

3.5 Reporting Obligations. As long as any Holder shall own Registrable Securities, the Company, at all times while it shall
be reporting 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 and to promptly furnish the Holders with true and complete copies of all such filings. 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 Registrable Securities 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. 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. 
 3.6 Limitations on Registration Rights. Notwithstanding anything herein to the
contrary, (i) none of the IPO Underwriters may exercise its rights under Sections 2.1 and 2.2 hereunder after five (5) and seven (7) years, respectively, after the effective date of the registration
statement relating to the Company’s initial public offering and (ii) the Representatives may not exercise their rights under Section 2.1 more than once. 

4. INDEMNIFICATION AND CONTRIBUTION. 

4.1 Indemnification by the Company. The Company agrees to indemnify, to the extent permitted by law, and hold harmless each
Holder of Registrable Securities, its officers and directors, and each person who controls such Holder (within the meaning of the Securities Act), from and against any expenses, losses, judgments, claims, damages or liabilities (including reasonable
attorney’s fees), whether joint or several, arising out of or based upon any untrue or alleged untrue statement of material fact contained in any Registration Statement, Prospectus or preliminary Prospectus, or any amendment or supplement to
any of them, 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 is contained in any information furnished in writing to the
Company by the Holder expressly for use therein. The Company also shall indemnify any Underwriter of the Registrable Securities, their officers and directors, and each person who controls such Underwriter (within the meaning of the Securities Act)
on substantially the same basis as that of the indemnification provided above in this Section 4.1. 

  
 10 













 4.2 Indemnification by Holders of Registrable Securities. 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 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 any losses,
claims, damages, liabilities and expenses (including without limitation reasonable attorneys’ fees) resulting from any untrue statement of material fact contained in the Registration Statement, Prospectus or preliminary Prospectus or any
amendment thereof or supplement thereto or any 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, 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. Each Holder shall indemnify
any Underwriter of Registrable Securities sold by such Holder, 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. 
 4.3 Conduct of Indemnification Proceedings. 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. 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. 
 4.4 Contribution. 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; provided, that the liability of any Holder under this Section
4.4 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 Sections 4.1-4.3 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 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 this Section 4.4. 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 Section 4.4 from any person who was not guilty of such fraudulent misrepresentation. 

  
 11 













 4.4 Survival. 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.

 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; Electronic Signatures. This Agreement may be executed in counterparts, each of which when so executed
shall be deemed to be an original, and all of which when 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 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 Modifications and Amendments. 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, 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, that notwithstanding the foregoing, any amendment hereto or waiver hereof that adversely affects one Holder, 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 (in such capacity) shall require the consent of the Holder 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. 

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 Investors 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. 

  
 13 













 6.11 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. 

6.12 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 otherwise) arising out of, connected with or relating to this Agreement, the transactions contemplated hereby, or the actions of the Investors in the negotiation,
administration, performance or enforcement hereof. 
 6.13 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 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. The provisions of Section 3.5 and Article IV shall
survive any termination.
