 Section 2. Demand
Registrations. 
 (a) Requests for Registration. Subject to the terms and conditions of this Agreement, at any time after
the earlier of [***] or the [***] anniversary of the date on which the Company has completed a Qualified Public Offering, the holders of at least [***] of the Registrable Securities may request registration under the Securities Act of at least [***]
of their aggregate Registrable Securities or such lesser number of shares resulting in aggregate offering proceeds of at least [***] on Form S-1 or any similar long-form registration (“Long-Form
Registrations”), and the holders of at least [***] of the Registrable Securities may request registration under the Securities Act of all or any portion of their Registrable Securities on Form S-2 or S-3 or any similar short-form registration (“Short-Form Registrations”) if available. All registrations requested pursuant to this Section 2(a) are referred to herein as
“Demand Registrations.” Each request for a Demand Registration shall specify the approximate number of Registrable Securities requested to be registered and the anticipated per share price range for such offering. Within [***] after
receipt of any such request, the Company shall give written notice of such requested registration to all other holders of Registrable Securities and, subject to the terms of Section 2(d) hereof, shall include in such
registration (and in all related registrations and qualifications under state blue sky laws or in compliance with other registration requirements and in any related underwriting) all Registrable Securities with respect to which the Company has
received written requests for inclusion therein within [***] after the receipt of the Company’s notice. 
 (b) Long-Form
Registrations. The holders of Registrable Securities shall be entitled to request not more than [***] Long-Form Registrations in the aggregate, and the Company shall pay all Registration Expenses. A registration shall not count as one of the
permitted Long-Form Registrations until it has become effective (unless such Long-Form Registration has not become effective due solely to the fault of the holders requesting such registration). 

(c) Short-Form Registrations. In addition to the Long-Form Registrations provided pursuant to Section 2(b),
the holders of Registrable Securities shall be entitled to request an unlimited number of Short-Form Registrations and the Company shall pay all Registration Expenses; provided that the aggregate offering value of the Registrable Securities
requested to be registered in any Short-Form Registration must equal at least [***] and; provided, further that the Company shall not be obligated to effect more than [***] Short-Form Registrations in any
12-month period. Demand Registrations shall be Short-Form Registrations whenever the Company is permitted to use any applicable short form and if the managing underwriters (if any) agree to the use of a
Short-Form Registration. After the Company has become subject to the reporting requirements of the Securities Exchange Act of 1934, as amended, and the rules and regulations promulgated thereunder (the “Exchange Act”), the Company
shall use its best efforts to make Short-Form Registrations available for the sale of Registrable Securities. 

  
 3 













 (d) Priority on Demand Registrations. The Company shall not include in any Demand
Registration any securities which are not Registrable Securities without the prior written consent of the holders of at least [***] of the Registrable Securities included in such registration. If a Demand Registration is an underwritten offering and
the managing underwriters advise the Company in writing that in their opinion the number of Registrable Securities and, if permitted hereunder, other securities requested to be included in such offering exceeds the number of Registrable Securities
and other securities, if any, which can be sold the Company shall include in such registration (i) first, the Registrable Securities requested to be included in such registration, pro rata among the holders thereof on the basis of the number of
Registrable Securities owned by each such holder and (ii) second, if permitted hereunder, other securities requested to be included in the registration. 

(e) Restrictions on Demand Registrations. The Company shall not be obligated to effect any Demand Registration within 12 months after
the effective date of a previous Long-Form Registration or a previous registration in which the holders of Registrable Securities were given piggyback rights pursuant to Section 3 and in which there was no reduction in the
number of Registrable Securities requested to be included. The Company may postpone for up to [***] the filing or the effectiveness of a registration statement for a Demand Registration if the Company’s board of directors determines in its
reasonable good faith judgment that such Demand Registration would reasonably be expected to have a material adverse effect on the Company or any of its subsidiaries; provided that in such event, the holders of Registrable Securities
initially requesting such Demand Registration shall be entitled to withdraw such request and, if such request is withdrawn, such Demand Registration shall not count as one of the permitted Demand Registrations hereunder and the Company shall pay all
Registration Expenses in connection with such registration. The Company may delay a Demand Registration hereunder only once in any twelve-month period. 

(f) Selection of Underwriters. The holders of [***] of the Registrable Securities included in any Demand Registration shall have the
right to select the investment banker(s) and manager(s) to administer the offering, subject to the Company’s approval which shall not be unreasonably withheld or delayed. 

(g) Other Registration Rights. The Company represents and warrants that it is not a party to, or otherwise subject to, any other
agreement granting registration rights to any other Person with respect to any securities of the Company. Except as provided in this Agreement, the Company shall not grant to any Persons the right to request the Company to register any equity
securities of the Company, or any securities convertible or exchangeable into or exercisable for such securities, without the prior written consent of the holders of at least [***] of the Registrable Securities; provided that the
Company may grant rights to other Persons (i) to participate in Piggyback Registrations so long as such rights are subordinate to the rights of the holders of Registrable Securities with respect to such Piggyback Registrations as set forth in
Sections 3(c) and 3(d) hereof, (ii) to request registrations so long as the holders of Registrable Securities are entitled to participate in any such registrations with such Persons pro rata on the basis of the number of shares
owned by each such holder or (iii) who become a party to this Agreement in accordance with Subsection 9(m) hereof.

 Section 3. Piggyback Registrations. 

(a) Right to Piggyback. Whenever the Company proposes to register any of its securities under the Securities Act (other than pursuant
to a Demand Registration or the Company’s initial Public Offering) and the registration form to be used may be used for the registration of Registrable Securities (a “Piggyback Registration”), the Company shall give prompt
written notice (in any event within [***] after its receipt of notice of any exercise of demand registration rights other than under this Agreement) to all holders of at least [***] of the Registrable Securities of its intention to effect such a
registration and, subject to the terms of Sections 3(c) and 3(d) hereof, shall include in such registration (and in all related registrations or qualifications under blue sky laws or in compliance with other registration requirements
and in any related underwriting) all Registrable Securities with respect to which the Company has received written requests for inclusion therein within [***] after the receipt of the Company’s notice. Notwithstanding the foregoing, the Company
shall not be required to include any Registrable Securities in a Piggyback Registration Statement if such Registrable Securities can then be sold pursuant to Rule 144(k) under the Securities Act and the holder of such Registrable Securities is
not deemed an Affiliate under the Securities Act. 
 (b) Piggyback Expenses. The Registration Expenses of the holders of Registrable
Securities shall be paid by the Company in all Piggyback Registrations. 
 (c) Priority on Primary Registrations. If a Piggyback
Registration is an underwritten primary registration on behalf of the Company, and the managing underwriters advise the Company in writing that in their opinion the number of securities requested to be included in such registration exceeds the
number which can be sold in an orderly manner in such offering within a price range acceptable to the Company, the Company shall include in such registration (i) first, the securities the Company proposes to sell, (ii) second, the
Registrable Securities requested to be included in such registration, pro rata among the holders of such Registrable Securities on the basis of the number of Registrable Securities owned by each such holder, and (iii) third, other securities
requested to be included in such registration. 
 (d) Priority on Secondary Registrations. If a Piggyback Registration is an
underwritten secondary registration on behalf of holders of the Company’s securities, and the managing underwriters advise the Company in writing that in their opinion the number of securities requested to be included in such registration
exceeds the number which can be sold in such offering without adversely affecting the marketability of the offering, the Company shall include in such registration (i) first, the securities requested to be included therein by the holders
requesting such registration, (ii) second, the Registrable Securities requested to be included in such registration, pro rata among the holders of such Registrable Shares on the basis of the number of Registrable Shares owned by each such
holder, and (iii) third, other securities requested to be included in such registration; provided that in any event the holders of Registrable Securities shall not be cut back to less than [***] of the total offering, and only after all
other holders are first cut back in total. 
 (e) Other Registrations. If the Company has previously filed a registration statement
with respect to Registrable Securities pursuant to Section 2 or pursuant to this Section 3, and if such previous registration has not been withdrawn or abandoned, the Company shall not file or
cause to be effected any other registration of any of its equity securities or securities convertible or exchangeable into or exercisable for its equity securities under the Securities Act (except on Form S-8
or any successor form), whether on its own behalf or at the request of any holder or holders of such securities, until a period of at least [***] has elapsed from the effective date of such previous registration. 

  
 5 













 Section 4. Holdback Agreements. The Company shall not effect any public sale or
distribution of its equity securities, or any securities convertible into or exchangeable or exercisable for such securities, during the [***] prior to and during the [***] period beginning on the effective date of any underwritten Demand
Registration or any underwritten Piggyback Registration (except as part of such underwritten registration or pursuant to registrations on Form S-8 or any successor form), unless the underwriters managing the
registered public offering otherwise agree. 
 Section 5. Registration Procedures.  

(a) Whenever the holders of Registrable Securities have requested that any Registrable Securities be registered pursuant to this Agreement,
the Company shall use its reasonable best efforts to effect the registration and the sale of such Registrable Securities in accordance with the intended method of disposition thereof, and pursuant thereto the Company shall as expeditiously as
possible: 
 (i) prepare and file with the Securities and Exchange Commission a registration statement, and all amendments
and supplements thereto and related prospectuses as may be necessary to comply with applicable securities laws with respect to such Registrable Securities and use its best efforts to cause such registration statement to become effective;
provided that before filing a registration statement or prospectus or any amendments or supplements thereto, the Company shall furnish to the counsel selected by the holders of [***] of the Registrable Securities covered by such registration
statement copies of all such documents proposed to be filed, which documents shall be subject to the review and reasonable comment of such counsel); 

(ii) notify each holder of such Registrable Securities of the effectiveness of each registration statement filed hereunder and
prepare and file with the Securities and Exchange Commission such amendments and supplements to such registration statement and the prospectus used in connection therewith as may be necessary to keep such registration statement effective for a
period of not less than [***] (or such lesser period until all such Registrable Securities have been sold) and comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such registration statement
during such period in accordance with the intended methods of disposition by the sellers thereof set forth in such registration statement; 

(iii) furnish to each seller of Registrable Securities such number of copies of such registration statement, each amendment and
supplement thereto, the prospectus included in such registration statement (including each preliminary prospectus) and such other documents as such seller may reasonably request in order to facilitate the disposition of the Registrable Securities
owned by such seller; 
 (iv) use its best efforts to register or qualify such Registrable Securities under such other
securities or blue sky laws of such jurisdictions as any seller reasonably requests and do any and all other acts and things which may be reasonably necessary or advisable to enable such seller to consummate the disposition in such jurisdictions of
the Registrable Securities owned by such seller; provided that the Company shall not be required to (i) qualify generally to do business in any jurisdiction where it would not otherwise be required to qualify but for this subsection,
(ii) subject itself to taxation in any such jurisdiction or (iii) consent to general service of process in any such jurisdiction); 

  
 6 













 (v) notify each seller of such Registrable Securities, at any time when a
prospectus relating thereto 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 contains an untrue statement of a material fact or omits any
fact necessary to make the statements therein not misleading, and, at the request of any such seller, the Company shall prepare a supplement or amendment to such prospectus so that, as thereafter delivered to the purchasers of such Registrable
Securities, such prospectus shall not contain an untrue statement of a material fact or omit to state any fact necessary to make the statements therein not misleading; 

(vi) cause all such Registrable Securities to be listed on each securities exchange on which similar securities issued by the
Company are then listed; 
 (vii) provide a transfer agent and registrar for all such Registrable Securities not later than
the effective date of such registration statement; 
 (viii) enter into such customary agreements (including underwriting
agreements in customary form) as the holders of [***] of the Registrable Securities being sold or the underwriters, if any, reasonably request in order to expedite or facilitate the disposition of such Registrable Securities; 

(ix) make available for inspection by any seller of Registrable Securities, any underwriter participating in any disposition
pursuant to such registration statement and any attorney, accountant or other agent retained by any such seller or underwriter, all financial and other records, pertinent corporate documents and properties of the Company, and cause the
Company’s officers, directors, employees and independent accountants to supply all information reasonably requested by any such seller, underwriter, attorney, accountant or agent in connection with such registration statement; 

(x) otherwise use its best efforts to comply with all applicable rules and regulations of the Securities and Exchange
Commission, and make available to its security holders, as soon as reasonably practicable, an earnings statement covering the period of at least [***] beginning with the first day of the Company’s first full calendar quarter after the effective
date of the registration statement, which earnings statement shall satisfy the provisions of Section 11(a) of the Securities Act and Rule 158 thereunder; 

(xi) permit any holder of Registrable Securities which holder, in its sole and exclusive judgment, might be deemed to be an
underwriter or a controlling person of the Company, to participate in the preparation of such registration or comparable statement and to require the insertion therein of material, furnished to the Company in writing, which in the reasonable
judgment of such holder and its counsel should be included; 

  
 7 













 (xii) in the event of the issuance of any stop order suspending the
effectiveness of a registration statement, or of any order suspending or preventing the use of any related prospectus or suspending the qualification of any common stock included in such registration statement for sale in any jurisdiction, the
Company shall use its best efforts promptly to obtain the withdrawal of such order. 
 (xiii) use its reasonable best efforts
to cause such Registrable Securities covered by such registration statement to be registered with or approved by such other governmental agencies or authorities as may be necessary to enable the sellers thereof to consummate the disposition of such
Registrable Securities; and 
 (xiv) in the event the Registrable Securities are sold pursuant to an underwritten public
offering, use its reasonable best efforts to obtain a cold comfort letter from the Company’s independent public accountants and a legal opinion from the Company’s counsel, in customary form and covering such matters of the type customarily
covered by cold comfort letters and legal opinions, as the case may be; provided that such Registrable Securities constitute at least [***] of the securities covered by such registration statement. 

(b) If the Company has delivered a prospectus to the Registrable Securities and after having done so the prospectus is amended to comply with
the requirements of the Securities Act, the Company shall promptly notify the holders of Registrable Securities and, if requested, the holders of Registrable Securities shall immediately cease making offers of Registrable Securities and return all
prospectuses to the Company. The Company shall promptly provide the holders of Registrable Securities with revised prospectuses and, following receipt of the revised prospectuses, the holder of Registrable Securities shall be free to resume making
offers of Registrable Securities. 
 (c) In the event that, in the judgment of the Company, it is advisable to suspend use of a prospectus
included in a registration statement due to pending material developments or other events that have not yet been publicly disclosed and as to which the Company believes public disclosure would be detrimental to the Company, the Company shall notify
all holders of Registrable Securities to such effect, and, upon receipt of such notice, each such holder of Registrable Securities shall immediately discontinue any sales of Registrable Shares pursuant to such registration statement until such
holder of Registrable Securities has received copies of a supplemented or amended prospectus or until such holder of Registrable Securities is advised in writing by the Company that the then current prospectus may be used and has received copies of
any additional or supplemental filings that are incorporated or deemed incorporated by reference in such prospectus.

 (a) All expenses incurred by the Company in connection with the performance of or compliance with
this Agreement, including without limitation all registration, qualification and filing fees, fees and expenses of compliance with securities or blue sky laws, printing expenses, messenger and delivery expenses, fees and disbursements of custodians,
and fees and disbursements of counsel for the Company and all independent certified public accountants, underwriters (excluding underwriting discounts and commissions) and other Persons retained by the Company (all such expenses being herein called
“Registration Expenses”), shall be borne by the Company, and the Company shall pay its internal expenses (including, without limitation, all 

  
 8 













 
salaries and expenses of its officers and employees performing legal or accounting duties), the expense of any annual audit or quarterly review, the expense of any liability insurance and the
expenses and fees for listing the securities to be registered on each securities exchange on which similar securities issued by the Company are then listed. Each Person that sells securities pursuant to a Demand Registration or Piggyback
Registration hereunder shall bear and pay all underwriting discounts and commissions applicable to the securities sold for such Person’s account. 

(b) The Company shall reimburse the holders of Registrable Securities included in any registration for the reasonable fees and disbursements
of one counsel chosen by the holders of [***] of the Registrable Securities requesting inclusion in such registration. 
 (c) To the extent
Registration Expenses are not required to be paid by the Company, each holder of securities included in any registration hereunder shall pay those Registration Expenses allocable to the registration of such holder’s securities so included, and
any Registration Expenses not so allocable shall be borne by all sellers of securities included in such registration in proportion to the aggregate selling price of the securities to be so registered. 

Section 7. Indemnification. 

(a) The Company agrees to indemnify, to the extent permitted by law, each holder of Registrable Securities, its officers and directors and
each Person who controls such holder (within the meaning of the Securities Act) against all losses, claims, actions, damages, liabilities and expenses caused by (i) 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, or (ii) any violation by the Company of any rule or regulation promulgated under the Securities Act applicable to the Company and relating to action or inaction required of the Company in connection with any such registration,
qualification or compliance, and to pay to each holder of Registrable Securities, its officers and directors and each Person who controls such holder (within the meaning of the Securities Act), as incurred, any legal and any other expenses
reasonably incurred in connection with investigating, preparing or defending any such claim, loss, damage, liability or action, except insofar as the same are caused by untrue or alleged untrue statements of material fact or contained in any
information furnished in writing to the Company by or on behalf of such holder expressly for use therein or by such holder’s failure to deliver a copy of the registration statement or prospectus or any amendments or supplements thereto after
the Company has furnished such holder with a sufficient number of copies of the same. In connection with an underwritten offering, the Company shall indemnify such underwriters, their officers and directors and each Person who controls such
underwriters (within the meaning of the Securities Act) to the same extent as provided above with respect to the indemnification of the holders of Registrable Securities. 

(b) In connection with any registration statement in which a holder of Registrable Securities is participating, each 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 each Person who controls the Company (within the meaning of the Securities Act) against any losses, claims, damages, liabilities and expenses 

  
 9 













 
resulting from any untrue or alleged untrue statement of material fact contained in the 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; provided that the obligation to indemnify shall be individual, not joint and several, for each holder and shall be limited to the net amount of proceeds received by such holder from the sale
of Registrable Securities pursuant to such registration statement. 
 (c) Any Person entitled to indemnification hereunder 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 except
to the extent such failure has adversely affected the indemnifying party and (ii) 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 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. 
 (d) If the indemnification
provided for in this Section 7 is held by a court of competent jurisdiction to be unavailable to an indemnified party or is otherwise unenforceable with respect to any loss, claim, damage, liability or action referred to
herein, then the indemnifying party, in lieu of indemnifying such indemnified party hereunder, shall contribute to the amounts paid or payable by such indemnified party as a result of such loss, claim, damage, liability or action in such proportion
as is appropriate to reflect the relative fault of the indemnifying party on the one hand and of the indemnified party on the other hand in connection with the statements or omissions which resulted in such loss, claim, damage, liability or action
as well as any other relevant equitable considerations; provided that the maximum amount of liability in respect of such contribution shall be limited, in the case of each seller of Registrable Securities, to an amount equal to the net
proceeds actually received by such seller from the sale of Registrable Securities effected pursuant to such registration. The relative fault of the indemnifying party and of the indemnified party shall be determined by reference to, among other
things, whether the untrue or alleged untrue statement of a material fact or the omission to state a material fact relates to information supplied by the indemnifying party or by the indemnified party and the parties’ relative intent,
knowledge, access to information and opportunity to correct or prevent such statement or omission. The parties hereto agree that it would not be just or equitable if the contribution pursuant to this Section 7(d) were to be
determined by pro rata allocation or by any other method of allocation that does not take into account such equitable considerations. The amount paid or payable by an indemnified party as a result of the losses, claims, damages, liabilities or
expenses referred to herein shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending against any action or claim which is the subject hereof. 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 is not guilty of such fraudulent misrepresentation. No party shall be liable for contribution with
respect to any action, suit, proceeding or claim settled without its prior written consent, which consent shall not be unreasonably withheld, conditioned or delayed. 

  
 10 













 (e) The indemnification and contribution 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. 

(f) No indemnifying party shall, except with the consent of the indemnified party, consent to the entry of any judgment or enter into any
settlement that does not include as an unconditional term thereof giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect to such claim or litigation. 

Section 8. Participation in Underwritten Registrations. No Person may participate in any registration hereunder which is
underwritten unless such Person (i) agrees to sell such Person’s securities on the basis provided in any underwriting arrangements approved by the Person or Persons entitled hereunder to approve such arrangements and (ii) completes
and executes all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents required under the terms of such underwriting arrangements; provided that no holder of Registrable Securities included in any underwritten
registration shall be required to make any representations or warranties to the Company or the underwriters (other than representations and warranties regarding such holder and such holder’s intended method of distribution) or to undertake any
indemnification obligations to the Company or the underwriters with respect thereto, except as otherwise provided in Section 7 hereof. 

Section 9. Miscellaneous. 

(a) No Inconsistent Agreements. The Company shall not hereafter enter into any agreement with respect to its securities which is
inconsistent with or violates the rights granted to the holders of Registrable Securities in this Agreement. 
 (b) Remedies. Any
Person having rights under any provision of this Agreement shall be entitled to enforce such rights specifically (without posting a bond or other security), to recover damages caused by reason of any breach of any provision of this Agreement and to
exercise all other rights granted by law. The parties hereto agree and acknowledge that money damages would not be an adequate remedy for any breach of the provisions of this Agreement and that, in addition to any other rights and remedies existing
in its favor, any party shall be entitled to specific performance and/or other injunctive relief from any court of law or equity of competent jurisdiction (without posting any bond or other security) in order to enforce or prevent violation of the
provisions of this Agreement. 
 (c) Amendments and Waivers. Except as otherwise provided herein, the provisions of this Agreement
may be amended or waived only with the prior written consent of the Company and the Required Investors. Notwithstanding the foregoing, this Agreement may not be amended or terminated and the observance of any term hereof may not be waived with
respect to any Stockholder without the written consent of such Stockholder, unless such amendment, termination, or waiver applies to all Stockholders in the same fashion. The failure of any party to enforce any of the provisions of this Agreement
shall in no way be construed as a waiver of such provisions and shall not affect the right of such party thereafter to enforce each and every provision of this Agreement in accordance with its terms. 

  
 11 













 (d) Successors and Assigns. All covenants and agreements in this Agreement by or on
behalf of any of the parties hereto shall bind and inure to the benefit of the respective successors and assigns of the parties hereto whether so expressed or not. In addition, whether or not any express assignment has been made, the provisions of
this Agreement which are for the benefit of purchasers or holders of Registrable Securities are also for the benefit of (i) a transferee or assignee of all of a holder’s Registrable Securities; (ii) another holder of Registrable
Securities that already possesses registration rights; (iii) a transferee or assignee of a portion of a holder’s Registrable Securities so long as such transferee or assignee is acquiring at least [***] of the Company’s outstanding
Common Stock on a fully-diluted basis; provided the Company is given written notice thereof; or (iv) to an affiliated limited partnership, a limited partner, general partner, member or other Affiliate of any holder of Registrable
