Company, blue sky fees and expenses, accounting fees and the expense of any special audits incident to or required by any such registration (but excluding the compensation of regular employees of the Company which shall be paid in any event by the
Company). 
 2 







 “Registrable Securities” means any shares of Common Stock which are
Eligible Securities, any shares of Common Stock issuable upon the exercise or conversion, as applicable, of Eligible Securities; provided, however, that shares of Common Stock shall be treated as Registrable Securities only if and so
long as they have not been (A) sold to or through a broker or dealer or underwriter in a public distribution or a public securities transaction, (B) sold in a transaction exempt from the registration and prospectus delivery requirements of
the Securities Act under Section 4(1) thereof so that all transfer restrictions and restrictive legends with respect thereto are removed upon the consummation of such sale or (C) sold in transactions in which the rights granted under this
Section 1 are not assigned in accordance with this Agreement. 
 “Restricted Securities” shall mean the

this Agreement. Each Investor will cause any proposed purchaser, assignee, transferee or pledgee of its Eligible Securities to agree to take and hold such securities subject to the provisions and upon the conditions specified in this Agreement.

 1.3 Restrictive Legend. Each certificate representing Eligible Securities shall (unless otherwise permitted by the
provisions of Section 1.4 below) be stamped or otherwise imprinted with a legend in the following form (in addition to any legend required under applicable state securities laws): 

“THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED FOR INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT
OF 1933, AS AMENDED (THE “SECURITIES ACT”). SUCH SHARES MAY NOT BE SOLD, TRANSFERRED OR PLEDGED IN THE ABSENCE OF SUCH REGISTRATION OR UNLESS THE COMPANY RECEIVES AN OPINION OF COUNSEL (WHICH MAY BE COUNSEL FOR THE COMPANY) OR OTHER
EVIDENCE REASONABLY ACCEPTABLE TO IT STATING THAT SUCH SALE OR TRANSFER IS EXEMPT FROM THE REGISTRATION AND PROSPECTUS DELIVERY REQUIREMENTS OF THE SECURITIES ACT.” 
 3 







 “THE SHARES REPRESENTED BY THIS CERTIFICATE MAY BE TRANSFERRED ONLY IN ACCORDANCE WITH
THE TERMS OF AN AGREEMENT BETWEEN THE COMPANY AND THE STOCKHOLDER, A COPY OF WHICH IS ON FILE WITH THE SECRETARY OF THE COMPANY.” 
 “THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO A MARKET STAND-OFF AGREEMENT IN THE EVENT OF A PUBLIC OFFERING, A COPY OF WHICH IS ON FILE WITH THE SECRETARY OF THE COMPANY.”

 Each Investor consents to the Company making a notation on its records and giving instructions to any transfer agent of the
Restricted Securities in order to implement the restrictions on transfer established in this Section 1. 
 1.4 Notice of
Proposed Transfers. Each Holder of each certificate representing Restricted Securities, by acceptance thereof, agrees to comply in all respects with the restrictions on transfer contained in Sections 1.2, 1.3, 1.4, 1.13 and 1.14 of this Agreement.
Prior to any proposed sale, assignment, transfer or pledge of any Restricted Securities (other than any transfer not involving a change in beneficial ownership), unless there is in effect a registration statement under the Securities Act covering
the proposed transfer, the Holder thereof shall give written notice to the Company of such Holder’s intention to effect such transfer, sale, assignment or pledge. Each such notice shall describe the manner and circumstances of the proposed
transfer, sale, assignment or pledge in sufficient detail, and shall be accompanied at such Holder’s expense by either (i) a written opinion of legal counsel who shall, and whose legal opinion shall be, reasonably satisfactory to the
Company, addressed to the Company, to the effect that the proposed transfer of the Restricted Securities may be effected without registration under the Securities Act, or (ii) a “no action” letter from the Commission to the effect
that the transfer of such securities without registration will not result in a recommendation by the staff of the Commission that action be taken with respect thereto, or (iii) any other evidence reasonably satisfactory to counsel to the
Company, whereupon the Holder of such Restricted Securities shall be entitled to transfer such Restricted Securities in accordance with the terms of the notice delivered by the Holder to the Company. Each certificate evidencing the Restricted
Securities transferred as above provided shall bear, except if such transfer is made pursuant to Rule 144, the appropriate restrictive legend set forth in Section 1.3 above, except that such certificate shall not bear such restrictive legend
if, in the opinion of counsel for such Holder and the Company, such legend is not required in order to establish compliance with any provisions of the Securities Act or this Agreement. 

Notwithstanding the foregoing, no such registration statement, opinion of counsel or “no action” letter shall be necessary for
a transfer by a Holder which is (A) a partnership to its partners or former partners in accordance with partnership interests, (B) a corporation to its stockholders in accordance with their interest in the corporation, (C) a limited
liability company to its members or former members in accordance with their interest in the limited liability company, or (D) to the Holder’s family member or trust for the benefit of an individual Holder; 

4 







 
provided that in each case the transferee will be subject to the terms of this Agreement to the same extent as if he were an original Holder hereunder. 

1.5 Requested Registration. 
 (a) Request for Registration. In case the Company shall receive from Initiating Holders a written request that the Company effect any registration with respect to a public offering, the reasonably
anticipated aggregate price to the public of which would exceed $7,500,000, the Company will: 
 (i) promptly give written
notice of the proposed registration to all other Holders; and 
 (ii) use its best efforts to effect as soon as practicable
such registration (including, without limitation, the execution of an undertaking to file post-effective amendments, appropriate qualification under applicable blue sky or other state securities laws and appropriate compliance with applicable
regulations issued under the Securities Act and any other governmental requirements or regulations) as may be so requested and as would permit or facilitate the sale and distribution of all or such portion of such Registrable Securities as are
specified in such request, together with all or such portion of the Registrable Securities of any Holder or Holders joining in such request as are specified in a written request received by the Company within 15 days after receipt of the written
notice from the Company; provided, however, that the Company shall not be obligated to take any action to effect any such registration pursuant to this Section 1.5: 

(1) In any particular jurisdiction in which the Company would be required to execute a general consent to service of process in
effecting such registration unless the Company is already subject to service in such jurisdiction and except as may be required by the Securities Act; 
 (2) Prior to 6 months following the closing of the Company’s Initial Public Offering; 
 (3) If the Company has already effected a registration pursuant to Section 1.7 or this Section 1.5 within the last 6 months; 

(4) During the period starting with the date 60 days prior to the Company’s estimated date of filing of, and ending on the date
three months immediately following the effective date of, any registration statement (other than a registration of Securities in a Rule 145 transaction or with respect to an employee benefit plan) pertaining to Securities of the Company (subject to
Section 1.6(a) hereof), provided that the Company is actively employing in good faith all reasonable efforts to cause such registration statement to be filed and become effective and that the Company provides the Initiating Holders written
notice of its intent to file such registration statement within 30 days of receiving the request for registration from the Initiating Holders; 
 5 







 (5) After the Company has effected two registrations pursuant to this Section 1.5; or

 (6) If the Company shall furnish to such Holders a certificate, signed by the President of the Company, stating that in the
good faith judgment of the Board of Directors it would be seriously detrimental to the Company or its stockholders for a registration statement to be filed in the near future, in which case the Company’s obligation to use its best efforts to
register under this Section 1.5 shall be deferred for a period not to exceed 90 days from the date of receipt of written request from the Initiating Holders; provided, however, that the Company may not utilize this right more than once in any
12-month period. 
 Subject to the foregoing clauses (1) through (6), the Company shall file a registration statement
covering the Registrable Securities so requested to be registered as soon as practicable after receipt of the request of the Initiating Holders. 
 (b) Underwriting. If the Initiating Holders intend to distribute the Registrable Securities covered by their request by means of an underwriting, they shall so advise the Company as part of their
request made under Section 1.5(a), and the Company shall so advise the Holders as part of the notice given pursuant to Section 1.5(a)(i). The right of any Holder to registration pursuant to Section 1.5 shall be conditioned upon such
Holder’s participation in the underwriting arrangements required by this Section 1.5 and the inclusion of such Holder’s Registrable Securities in the underwriting, to the extent requested and provided herein. 

The Company shall (together with all Holders proposing to distribute their securities through such underwriting) enter into an
underwriting agreement in customary form with the managing underwriter selected for such underwriting by the Initiating Holders and reasonably acceptable to the Company. Notwithstanding any other provision of this Section 1.5, if the managing
underwriter advises the Company in writing that marketing factors require a limitation of the number of shares to be underwritten, then the Company shall so advise all Holders of Registrable Securities who indicated their intent to participate in
the registration in a timely manner, and the number of shares of Registrable Securities that may be included in the registration and underwriting shall be allocated among such Holders in proportion, as nearly as practicable, to the respective
amounts of Registrable Securities held by such Holders at the time of filing the registration statement, provided, however, that the number of shares of Registrable Securities to be included in such underwriting shall not be reduced
unless all other Securities are first entirely excluded from the underwriting. No Registrable Securities excluded from the underwriting by reason of the underwriter’s marketing limitation shall be included in such registration. To facilitate
the allocation of shares in accordance with the above provisions, the Company or the underwriters may round the number of shares allocated to any Holder to the nearest 100 shares. 

If any Holder of Registrable Securities disapproves of the terms of the underwriting, such person may elect to withdraw therefrom by
written notice to the Company, the managing underwriter and the Initiating Holders. The Registrable Securities so withdrawn shall also be withdrawn from registration and shall be subject to the provisions of Section 1.14 hereof. 

6 







 1.6 Company Registration. 

(a) Notice of Registration. If at any time or from time to time, the Company shall determine to register any Common Stock, either
for its own account or the account of a security holder or holders other than (i) a registration relating to employee benefit plans, (ii) a registration relating to the offer and sale of debt securities; (iii) a registration relating
to a Commission Rule 145 transaction, or (iv) a registration pursuant to Sections 1.5 or 1.7 hereof, the Company will: 

(i) promptly give to each Holder written notice thereof; and 
 (ii) include in such registration (and any related qualification under blue sky laws or other compliance), and in any underwriting involved therein, all the Registrable Securities specified in a written
request or requests made within 15 days after receipt of such written notice from the Company by any Holder. 
 (b)
Underwriting. If the registration of which the Company gives notice is for a registered public offering involving an underwriting, the Company shall so advise the Holders in a written notice given pursuant to this Section 1.6. In such
event, the right of any Holder to registration pursuant to this Section 1.6 shall be conditioned upon such Holder’s participation in such underwriting and the inclusion of Registrable Securities in the underwriting to the extent provided
herein. 
 All Holders proposing to distribute their securities through such underwriting shall (together with the Company and
the other holders distributing their securities through such underwriting) enter into an underwriting agreement in customary form with the managing underwriter selected for such underwriting by the Company. Notwithstanding any other provision of
this Section 1.6, if the managing underwriter advises the Company in writing that marketing factors require a limitation of the number of shares to be underwritten, then the Company shall so advise all Holders of Registrable Securities and the
number of shares of Registrable Securities that may be included in the registration and underwriting shall be allocated among all Holders thereof in proportion, as nearly as practicable, to the respective amounts of Registrable Securities held by
such Holders at the time of filing the registration statement, provided, however, that shares of Registrable Securities of Holders shall not be excluded from the underwriting unless all other securities (other than securities being
sold by the Company) are first entirely excluded from the underwriting; provided further that, unless such registration is in connection with the Company’s initial public offering, the number of Registrable Securities permitted to be included
therein shall in any event be at least 30% of the number of shares of Common Stock included therein. Subject to the foregoing sentence, no Registrable Securities excluded from the underwriting by reason of the underwriter’s marketing limitation
shall be included in such registration. To facilitate the allocation of shares in accordance with the above provisions, the Company or the underwriters may round the number of shares allocated to any Holder to the nearest 100 shares. The Company may
include shares of Common Stock held by stockholders other than Holders in a registration statement pursuant to this Section 1.6 to the extent that the amount of Registrable Securities otherwise includible in such registration 

7 







 
statement would not thereby be diminished and including such other shares will not, in the judgment of the underwriter, have a detrimental effect on the offering. 

If any Holder or other holder disapproves of the terms of any such underwriting, he or she may elect to withdraw therefrom by written
notice to the Company and the managing underwriter. The Registrable Securities so withdrawn shall also be withdrawn from such registration, and shall be subject to the provisions of Section 1.14 hereof. 

(c) Right to Terminate Registration. The Company shall have the right to terminate or withdraw any registration initiated by it
under this Section 1.6 prior to the effectiveness of such registration, whether or not any Holder has elected to include securities in such registration. 
 1.7 Registration on Form S-3. 
 (a) If any Holder or Holders request that
the Company file a registration statement on Form S-3 (or any successor form to Form S-3) for a public offering of Registrable Securities, the reasonably anticipated aggregate price to the public of which, net of underwriting discounts and
commissions, would exceed (i) $1,000,000, or (ii) the maximum amount of Registrable Securities subject to sale under Rule 144 with the then current volume restrictions, whichever is greater, and the Company is then entitled to use Form S-3
under applicable Commission rules to register the Registrable Securities for such an offering, the Company will: 
 (i)
promptly give written notice of the proposed registration to all other Holders; and 
 (ii) use its best efforts to effect as
soon as practicable such registration (including, without limitation, the execution of an undertaking to file post-effective amendments, appropriate qualification under applicable blue sky or other state securities laws and appropriate compliance
with applicable regulations issued under the Securities Act and any other governmental requirements or regulations) as may be so requested and as would permit or facilitate the sale and distribution of all or such portion of such Registrable
Securities as are specified in such request, together with all or such portion of the Registrable Securities of any Holder or Holders joining in such request as are specified in a written request received by the Company within 15 days after receipt
of the written notice from the Company; provided, however, that the Company shall not be obligated to take any action to effect any such registration pursuant to this Section 1.7: 

(1) in any particular jurisdiction in which the Company would be required to execute a general consent to service of process in
effecting such registration, qualification or compliance unless the Company is already subject to service in such jurisdiction and except as may be required by the Securities Act; 

(2) if the Company, within ten (10) days of the receipt of the request for registration pursuant to this Section 1.7, gives
notice of its bona fide intention to effect the filing of a registration statement with the Commission within ninety (90) days of receipt of such 
 8 







 
request (other than with respect to a registration statement relating to a Rule 145 transaction or an employee benefit plan or any other registration which is not appropriate for the registration
of Registrable Securities); 
 (3) during the period starting with the date sixty (60) days prior to the Company’s
estimated date of filing of, and ending on the date three months immediately following, the effective date of any registration statement pertaining to Securities of the Company (other than with respect to a registration statement relating to a Rule
145 transaction or an employee benefit plan), provided that the Company is actively employing in good faith all reasonable efforts to cause such registration statement to be filed and become effective; 

(4) if the Company has already effected a registration pursuant to Section 1.5 or this Section 1.7 within the last six months;
or 
 (5) if the Company shall furnish to such Holder or Holders a certificate signed by the President of the Company stating
that in the good faith judgment of the Board of Directors it would be seriously detrimental to the Company or its stockholders for registration statements to be filed in the near future, then the Company’s obligation to use its best efforts to
file a registration statement shall be deferred for a period not to exceed 90 days from the receipt of the request to file such registration by such Holder or Holders. 
 Subject to the foregoing clauses (1) through (5), the Company shall file a registration statement covering the Registrable Securities so requested to be registered as soon as practicable after
receipt of the request from the Holders. 
 (b) Underwriting. If the Holders requesting registration intend to distribute
the Registrable Securities covered by their request by means of an underwriting, they shall so advise the Company as part of their request made under Section 1.7(a), and the Company shall so advise the Holders as part of the notice given
pursuant to Section 1.7(a)(i). The substantive provisions of Section 1.5(b) shall otherwise apply to such registration. 
 1.8 Expenses of Registration. All Registration Expenses incurred in connection with any registration pursuant to Sections 1.5, 1.6 and 1.7 shall be borne by the Company. If a registration
proceeding is begun upon the request of Holders pursuant to Section 1.5 or 1.7, but such request is subsequently withdrawn at the request of the Holders, then the Holders of Registrable Securities to have been registered may either:
(i) bear all Registration Expenses of such proceeding, pro rata on the basis of the number of shares to have been registered, in which case the Company shall be deemed not to have effected a registration pursuant to Section 1.5(a) or
1.7(a) of this Agreement as applicable; or (ii) require the Company to bear all Registration Expenses of such proceeding, in which case the Company shall be deemed to have effected a registration pursuant to Section 1.5(a) or
Section 1.7(a) of this Agreement as applicable; provided, however, that if the withdrawal is based upon material adverse information concerning the Company of which the Initiating Holders were not aware at the time of such
request, no such registration under Sections 1.5(a) or 1.7(a) shall be deemed to have been effected. Unless otherwise stated, all other Selling Expenses relating to securities registered on behalf of the 

9 







 
Holders shall be borne by the Holders of the registered securities included in such registration pro rata on the basis of the number of shares so registered. 

1.9 Registration Procedures. In the case of each registration, qualification or compliance effected by the Company pursuant to
this Section 1, the Company will keep each Holder advised in writing as to the initiation of each registration, qualification and compliance and as to the completion thereof. At its expense the Company will: 

(a) Prepare and file with the Commission a registration statement with respect to such securities and use its best efforts to cause such
registration statement to become and remain effective for at least sixty (60) days or until the distribution described in the registration statement has been completed. 
 (b) Prepare and file with the Commission such amendments and supplements to such registration statement and the prospectus used in connection with such registration statement as may be necessary to comply
with the provisions of the Act with respect to the disposition of all securities covered by such registration statement. 
 (c)
Furnish to the Holders participating in such registration and to the underwriters of the securities being registered such reasonable number of copies of the registration statement, preliminary prospectus, final prospectus and such other documents as
such underwriters may reasonably request in order to facilitate the public offering of such securities. 
 (d) Use its best
efforts to register and qualify the securities covered by such registration statement under such other securities or Blue Sky laws of such jurisdictions as shall be reasonably requested by the Holders; provided that the Company shall not be required
in connection therewith or as a condition thereto to qualify to do business or to file a general consent to service of process in any such states or jurisdictions, unless the Company is already subject to service in such jurisdiction and except as
may be required by the Securities Act. 
 (e) In the event of any underwritten public offering, enter into and perform its
obligations under an underwriting agreement, in usual and customary form, with the managing underwriter of such offering. Each Holder participating in such underwriting shall also enter into and perform its obligations under such an agreement.

 (f) Notify each Holder of Registrable Securities covered by such registration statement 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, as then in effect, includes an untrue statement of a material fact or
omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances then existing. 
 (g) Cause all such Registrable Securities registered pursuant hereunder to be listed on each securities exchange, or quoted in a U.S. automated inter-dealer quotation system, as the case may be, on which
similar securities issued by the Company are then listed, or quoted. 
 10 







 (h) Provide a transfer agent and registrar for all Registrable Securities registered
pursuant hereunder and a CUSIP number for all such Registrable Securities, in each case not later than the effective date of such registration. 
 1.10 Indemnification. 
 (a) The Company will indemnify and defend each
Holder, each of its officers, directors and partners, and each person controlling such Holder within the meaning of Section 15 of the Securities Act, with respect to which registration, qualification or compliance has been effected pursuant to
this Section 1, and each underwriter, if any, and each person who controls any underwriter within the meaning of Section 15 of the Securities Act, against all expenses, claims, losses, damages or liabilities (or actions in respect
thereof), including any of the foregoing incurred in settlement of any litigation, commenced or threatened, arising out of or based on any untrue statement (or alleged untrue statement) of a material fact contained in any registration statement,
prospectus, preliminary prospectus, free writing prospectus, offering circular or other document, or any amendment or supplement thereto, incident to any such registration, qualification or compliance, or based on any omission (or alleged omission)
to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances in which they were made, not misleading, or any violation or any alleged violation by the Company of the
Securities Act or the Exchange Act or any state securities law, or any rule or regulation promulgated thereunder, applicable to the Company in connection with any such registration, qualification or compliance, and the Company will reimburse each
such Holder, each of its officers and directors, and each person controlling such Holder, each such underwriter and each person who controls any such underwriter, for any legal and any other expenses reasonably incurred in connection with
investigating, preparing or defending any such claim, loss, damage, liability or action, as such expenses are incurred, provided that the Company will not be liable in any such case to the extent that any such claim, loss, damage, liability or
expense arises out of or is based on any untrue statement or omission or alleged untrue statement or omission, made in reliance upon and in conformity with written information furnished to the Company by an instrument duly executed by such Holder,
controlling person or underwriter and stated to be specifically for use therein. 
 (b) Each Holder, severally, and not jointly,
will, if Registrable Securities held by such Holder are included in the securities as to which such registration, qualification or compliance is being effected, indemnify the Company, each of its directors and officers, each underwriter, if any, of
the Company’s securities covered by such a registration statement, each person who controls the Company or such underwriter within the meaning of Section 15 of the Securities Act, and each other such Holder, each of its officers, directors
and partners and each person controlling such Holder within the meaning of Section 15 of the Securities Act, against all claims, losses, damages and liabilities (or actions in respect thereof) arising out of or based on any untrue statement (or
alleged untrue statement) of a material fact contained in any such registration statement, prospectus, offering circular or other document, or any omission (or alleged omission) to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, and will reimburse the Company, such Holders, such directors, officers, partners, persons, underwriters or control persons for any legal or any other expenses reasonably incurred in connection
with investigating or defending any such claim, loss, 
 11 







 
damage, liability or action, as such expenses are incurred, in each case to the extent, but only if and to the extent, that such untrue statement (or alleged untrue statement) or omission (or
alleged omission) is made in such registration statement, prospectus, offering circular or other document in reliance upon and in conformity with written information furnished to the Company by an instrument duly executed by such Holder and stated
to be specifically for use therein; provided, however, that the liability of a Holder pursuant to this Section 1.10(b) shall be limited to the proceeds (net of underwriting commissions and discounts and any contribution payments
made by such Holder pursuant to Section 1.10(d)) received by the Holder from the sale of securities of the Company pursuant to such Registration Statement. 
 (c) Each party entitled to indemnification under this Section 1.10 (the “Indemnified Party”) shall give notice to the party required to provide indemnification (the
“Indemnifying Party”) promptly after such Indemnified Party has actual knowledge of any claim as to which indemnity may be sought, and shall permit the Indemnifying Party to assume the defense of any such claim or any litigation
resulting therefrom, provided that counsel for the Indemnifying Party, who shall conduct the defense of such claim or litigation, shall be approved by the Indemnified Party (whose approval shall not unreasonably be withheld), and the Indemnified
Party may participate in such defense at such party’s expense; provided, however, that an Indemnified Party (together with all other Indemnified Parties which may be represented without conflict by one counsel) shall have the right to retain
one separate counsel, with the fees and expenses to be paid by the Indemnifying Party, if representation of such Indemnified Party by the counsel retained by the Indemnifying Party would be inappropriate due to actual or potential differing
interests between such Indemnified Party and any other party represented by such counsel in such proceeding. The failure of any Indemnified Party to give notice as provided herein shall not relieve the Indemnifying Party of its obligations under
this Section 1 unless the failure to give such notice is materially prejudicial to an Indemnifying Party’s ability to defend such action. No Indemnifying Party, in the defense of any such claim or litigation, shall, except with the consent
of each Indemnified Party, consent to entry of any judgment or enter into any settlement which 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. 
 (d) If recovery is not available under the foregoing indemnification provisions of this
Section 1.10, for any reason other than as specified therein, the parties entitled to indemnification by the terms thereof shall be entitled to contribution for liabilities and expenses from the parties liable for indemnification, except to the
extent that contribution is not permitted under Section 11(f) of the Securities Act. In determining the amount of contribution to which the respective parties are entitled, there shall be considered the relative benefits received by each party
from the offering of the securities (taking into account the portion of the proceeds of the offering realized by each), the parties’ relative knowledge and access to information concerning the matter with respect to which the claim was
asserted, the opportunity to correct and prevent any statement of omission, and any other equivalent considerations appropriate under the circumstances; provided, however, that the liability of a Holder pursuant to this Section 1.10(b) shall be
limited to the proceeds (net of underwriting commissions and discounts and any indemnification payments made by such Holder pursuant to Section 1.10(b)) received by the Holder from the sale of securities of the Company pursuant to such
Registration Statement. 
 12 







 1.11 Information by Holder. The Holder or Holders of Registrable Securities included
in any registration shall furnish to the Company such information regarding such Holder or Holders, the Securities held by them and the distribution proposed by such Holder or Holders as the Company may reasonably request in writing and as shall be
required in connection with any registration referred to in this Section 1. 
 1.12 Rule 144 Reporting. With a view
to making available the benefits of certain rules and regulations of the Commission which may at any time permit the sale of the Restricted Securities to the public without registration, after such time as a public market exists for the Common Stock
of the Company, the Company agrees to use its best efforts to: 
 (a) Make and keep public information available, as those terms

 (b) File with the Commission in a timely manner all reports and other documents required of
the Company under the Securities Act and the Exchange Act (at any time after it has become subject to such reporting requirements); and 
 (c) So long as an Investor owns any Restricted Securities, furnish to the Investor forthwith upon request a written statement by the Company as to its compliance with the reporting requirements of said
Rule 144 (at any time after ninety (90) days after the effective date of the first registration statement filed by the Company for an offering of its securities to the general public), and of the Securities Act and the Exchange Act (at any time
after it has become subject to such reporting requirements), a copy of the most recent annual or quarterly report of the Company, and such other reports and documents of the Company and other information in the possession of or reasonably obtainable
by the Company as an Investor may reasonably request in availing itself of any rule or regulation of the Commission allowing an Investor to sell any such securities without registration. 

1.13 Transfer of Registration Rights. The rights to cause the Company to register Registrable Securities granted the Investors
under Sections 1.5, 1.6 and 1.7 may be assigned to a transferee or assignee in connection with any transfer or assignment of Eligible Securities by an Investor; provided that (a) such transfer may otherwise be effected in accordance with
applicable securities laws, (b) notice of such assignment is given to the Company, (c) such transferee is a Permitted Transferee and (d) such transfer is pursuant to a written agreement acknowledged by the Company which acknowledgment
shall not be withheld if the transfer provisions of this Agreement are met. 
 1.14 Standoff Agreement. Each Holder
agrees in connection with any registration of the Company’s securities (other than a registration of debt securities, securities in a Rule 145 transaction or with respect to an employee benefit plan), upon notice by the Company or the
underwriters managing any underwritten public offering of the Company’s securities, not to sell, make any short sale of, loan, pledge (or otherwise encumber or hypothecate), grant any option for the purchase of, or otherwise directly or
indirectly dispose of any Securities (other than those 

  
 13 









 
(i) included in the registration or (ii) transferred to a Permitted Transferee who agrees to be similarly bound under this Section 1.14) without the prior written consent of the Company
and such managing underwriters for such period of time as the Board of Directors establishes pursuant to its good faith negotiations with such managing underwriters, which period shall not exceed 180 days in the case of the Initial Public Offering
or 90 days otherwise, provided that (i) such 180 day or 90 day period, as applicable, may be extended to the extent necessary to permit the underwriters to comply with NASD Rule 2711(f)(4), (ii) each officer and director of the Company and
each holder of at least 1% of the outstanding Common Stock (on a fully-diluted basis) shall enter into similar agreements or otherwise shall be bound by similar provisions, (iii) such restrictions shall not apply to equity securities purchased
in the Initial Public Offering or in the open market following the offering and (iv) any Investor may transfer any such shares to a Permitted Transferee, provided such Permitted Transferee is bound by comparable restrictions on transfer of such
shares. Each Holder hereby consents to the placement of stop transfer orders with the Company’s transfer agent in order to enforce the foregoing provision and agrees to execute a market standoff agreement with said underwriters in customary
form consistent with the provisions of this Section 1.14. 
 1.15 No Right to Delay Registration. No Holder shall
restrain, enjoin, or otherwise delay any registration hereunder, notwithstanding any controversy that might arise with respect to the interpretation or implementation of this Agreement. 

1.16 Termination of Rights. The rights of any particular Holder to cause the Company to register securities
under Sections 1.5, 1.6 and 1.7 shall terminate with respect to such Holder on the earlier of (i) the fifth
(5th) anniversary of the effective date of the
Company’s Initial Public Offering or (ii) such time as such Holder may sell all eligible securities held by such Holder in one day to the public without any restrictions imposed by the Company or pursuant to the Securities Act and without
registration under Section 5 of the Securities Act whether pursuant to Rule 144 or another applicable exemption. All other provisions hereof relating to registration rights shall continue to be effective despite any termination of such
registration rights pursuant to this section. 
 1.17 Limitations on Subsequent Registration Rights. From and after the
date of this Agreement, the Company shall not enter into any agreement granting any holder or prospective holder of any securities of the Company registration rights with respect to such securities unless (i) such new registration rights are
subordinate to the registration rights granted Holders hereunder and include similar market stand-off obligations or (ii) such new registration rights are approved by the Holders of a majority of the shares of Series C1 Preferred Stock and
Series D1 Preferred Stock then held by Holders, voting together as a single class.

accounts of the Company, at such reasonable times as such Investor may desire without disruption of the Company’s normal business and affairs for any reasonable purpose relating to its investment in the Company. The Company will provide each
Investor with such information regarding the Company as it shall reasonably request for purposes relating to its investment in the Company. The foregoing rights shall be limited by the Company’s reasonable need to keep sensitive business and
technical information confidential. 
 2.3 Confidentiality. Each Investor agrees that any information obtained by such
Investor pursuant to this Section 2 which is identified by the Company as being proprietary to the Company or otherwise confidential will not be disclosed without the prior written consent of the Company. Each Investor further acknowledges and
understands that any information so obtained which is identified by the Company as being “inside” non-public information will not be utilized by such Investor in connection with purchases and/or sales of the Company’s


  
 15 









 
securities except in compliance with applicable state and federal anti-fraud statutes. The provisions of this Section 2 shall not be in limitation of any rights which Investor may have with
respect to the books and records of the Company, or to inspect its properties or discuss its affairs, finances and accounts, under the laws of the jurisdictions in which it is incorporated. 

2.4 Directors and Officers Insurance. The Company shall maintain at all times directors and officers liability insurance in the
minimum amount of $5 million. Immediately prior to the Company’s Initial Public Offering, the Company shall increase the amount of directors and officers liability coverage to $10 million.

 SECTION 3 
 Right of First Offer For Company Securities 

3.1 Right of First Offer. Subject to the terms and conditions specified in this Section 3, the Company hereby grants to each
holder of Series C1 Preferred Stock and Series D1 Preferred Stock (“Senior Preferred Holders”) the right to purchase its Pro Rata Portion of New Securities (as defined below) in any future sales by the Company of its New Securities. Each
time the Company proposes to offer any New Securities, the Company shall first make an offering of such New Securities to each Senior Preferred Holder in accordance with the following provisions: 

(a) The Company shall deliver a notice (“Notice”) to each Senior Preferred Holder stating (i) its intention to
offer such New Securities for sale, (ii) the total number of New Securities to be offered by the Company (the “Offered Securities”), (iii) the price at which it proposes to offer the New Securities, (iv) the terms of
such offer, (v) such Senior Preferred Holder’s Pro Rata Portion of the Offered Securities, and (vi) identify the persons or entities (if known) to which or with which the Offered Securities are to be offered. 

(b) Each Senior Preferred Holder may elect in a written notice delivered to the Company within fifteen (15) business days after
receipt of the Notice (the “Acceptance Notice”), to purchase, at the price and on the terms specified in the Notice, New Securities in an amount up to such Senior Preferred Holder’s Pro Rata Portion by providing the Company with
written notice of its election. If a Senior Preferred Holder wishes to purchase an amount of New Securities greater than its Pro Rata Portion, it shall state in its Acceptance Notice the maximum number of New Securities it will purchase (the
“Oversubscription Amount”). In the event that any Senior Preferred Holder does not elect to purchase its entire Pro Rata Portion, each of the 
 16 







 
participating Senior Preferred Holders shall have the right to subscribe for and purchase such portion of such New Securities equal to such Senior Preferred Holder’s Oversubscription Amount
divided by the Oversubscription Amounts of all Senior Preferred Holders as set forth in the aforementioned reply notices. 
 (c)
An election by a Senior Preferred Holder an Investor pursuant to Section 3.1(b) to purchase Offered Securities shall not be considered a binding commitment unless and until the Company receives binding commitments to purchase on the terms and
conditions contained in the Notice substantially all of the Offered Securities which the Senior Preferred Holders have not elected to purchase. 
 3.2 Sale of Securities by Company. Within 60 days of the expiration of the period described in Section 3.1(b), any Offered Securities which the Senior Preferred Holders have not elected to
purchase may be sold by the Company to any person or persons at a price not less than, and upon terms no more favorable to the offeree than, those specified in the Notice. If the Company does not complete the sale of all such Offered Securities
within said 60 day period, the rights of the Senior Preferred Holders with respect to any such unsold Offered Securities shall be deemed to be revived. 
 3.3 Pro Rata Portion. A Senior Preferred Holder’s “Pro Rata Portion” of New Securities shall equal that percentage of the Offered Securities equal to the number of shares of Eligible
Securities held by such Senior Preferred Holder which are Registrable Securities divided by the total number of outstanding shares of Common Stock of the Company. For the purposes of the foregoing calculations, all outstanding options and warrants
to purchase Preferred Stock shall be deemed to be exercised and all Preferred Stock shall be deemed to have been converted into Common Stock at the prevailing conversion rate. 
 3.4 New Securities. The term “New Securities” shall mean an offering or series of related offerings of securities by the Company for purpose of raising capital in a minimum amount of
$100,000; provided that New Securities shall not include securities of the Company sold in any of the following transactions: (i) the issuance or sale of shares of Common Stock or options to purchase Common Stock to employees, officers,
directors or consultants for the primary purpose of soliciting or retaining their services or such other amount as shall have been approved by the Board of Directors, (ii) the issuance of Securities to banks, equipment lessors or other
financial institutions in connection with commercial leasing or debt financing transactions relating to the acquisition or lease of assets by the Company approved by the Board of Directors, (iii) any issuances of Securities in connection with
any stock split, stock dividend or recapitalization by the Company, (iv) the issuance of Securities to suppliers or third party service providers in connection with the provision of goods or services in the ordinary course of business pursuant
to transactions approved by the Board of Directors, (v) the issuance of Securities in connection with (A) the acquisition of another corporation by the Company by merger, purchase or other reorganization as a result of which the Company
owns not less than a majority of the voting securities of such entity or (B) the purchase of substantially all of the assets of another entity, provided, that in either case such issuances are approved by the Board of Directors, (vi) the
issuance of Preferred Stock or Common Stock issuable upon conversion of notes or conversion or exercise of any warrant to purchase Preferred Stock or Common Stock outstanding 
 17 







 
on the date of this Agreement, or (vii) the issuance and sale of Series D1 Preferred Stock pursuant to the Purchase Agreement. 

3.5 Termination of Right of First Offer. The right of first offer contained in this section shall not apply to and shall terminate
upon the closing of an Initial Public Offering. The rights granted pursuant to this Section 3 may be transferred only to a Permitted Transferee in connection with the transfer of 50% or more of its Eligible Securities.

act or omission of the manager or any other person. 
 (v) No attorney, agent, receiver or manager appointed in accordance with
this Agreement has authority to act on behalf of any Trustee in a way which exposes such
