Section 2 Registration Rights 

2.1 Demand Registration. 

(a) Request by Holders. If the Company shall receive at any time after the earlier of (i) three (3) years from the date of this
Agreement or (ii) six (6) months after the effective date of the first registration statement for a public offering of securities of the Company (other than a 

  
 3 








 
registration statement relating to the sale of securities to employees of the Company pursuant to a stock option, stock purchase or similar plan or an SEC Rule 145 transaction), or the subsequent
date on which all market stand-off agreements applicable to the offering have terminated, a written request from the Holders of at least 50% of the Registrable Securities then outstanding (“Initiating
Holders”) that the Company file a registration statement under the Securities Act covering the registration of fifty percent (50%) of the Registrable Securities then outstanding or such lesser amount as would have an anticipated aggregate
public offering price (after deduction for underwriter’s discounts and expenses related to the issuance) of not less than $25,000,000 and a per-share offering price of not less than $20.00 (as adjusted
for any stock dividends, combinations or splits with respect to such shares), then the Company shall, within ten (10) business days of the receipt of such written request, give written notice of such request (“Demand Notice”)
to all Holders and, as use commercially reasonable efforts to file as soon as practicable, and in any event within ninety (90) days after the date such request is given by the Initiating Holders, a registration statement under the Securities
Act covering all Registrable Securities that the Initiating Holders requested to be registered and any additional Registrable Securities requested to be included in such registration by any other Holders, as specified by notice given by each such
Holder to the Company within twenty (20) days of the date the Demand Notice is given, and in each case, subject to the limitations of this Section 2. 

(b) Underwriting. If the Initiating Holders intend to distribute the Registrable Securities covered by their request by means of an
underwriting, then they shall so advise the Company as a part of their request made pursuant to Section 2(a) and the Company shall include such information in the Demand Notice. In such event, the right of any Holder to
include such Holder’s Registrable Securities in such registration shall be conditioned upon such Holder’s participation in such underwriting and the inclusion of such Holder’s Registrable Securities in the underwriting (unless
otherwise mutually agreed by a majority in interest of the Initiating Holders and such Holder) to the extent provided herein. The underwriters will be selected by the Initiating Holders. Any Holders proposing to distribute their Registrable
Securities through such underwriting shall enter into an underwriting agreement in customary form with the managing underwriter or underwriters selected for such underwriting. Notwithstanding any other provision of this
Section 2.1, if the managing underwriters advise the Company in writing that marketing factors require a limitation of the number of securities to be underwritten, then the Company shall so advise all Holders of Registrable
Securities that would otherwise be registered and underwritten pursuant hereto, and the number of Registrable Securities that may be included in the underwriting shall be reduced as required by the underwriters and allocated among the Holders on a
pro rata basis according to the number of Registrable Securities held by each Holder requesting registration (including the Initiating Holders); provided, however, that the number of shares of Registrable Securities to be included in such
underwriting and registration shall not be reduced unless all other securities of the Company are first entirely excluded from the underwriting and registration. Any Registrable Securities excluded and withdrawn from such underwriting shall be
withdrawn from the registration. 
 (c) Exceptions to Registration Obligations. The Company shall not be obligated to effect, or to
take any action to effect, any registration pursuant to this Section2.1: (i) during the period starting with the date ninety (90) days prior to the Company’s good faith estimate of the date of filing of, and ending on the date that
is one hundred eighty (180) days after the effective date of, a Company-initiated registration, provided that the Company is actively employing in good faith commercially reasonable efforts to cause such registration statement to become
effective; (ii) 

  
 4 








 
after the Company has effected one (1) such registration; or (iii) if the Initiating Holders propose to dispose of shares of Registrable Securities that may be immediately registered on
Form S-3 pursuant to a request made pursuant to Section 2.3; or (iv) 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. A registration shall not be counted as
“effected” for purposes of this Section 2.1 until such time as the applicable registration statement has been declared effective by the Securities Exchange Commission, unless the Initiating Holders withdraw their
request for such registration. 
 (d) Deferral of Registration. Notwithstanding the foregoing, if the Company shall furnish to
Holders requesting registration pursuant to this Section 2.1 a certificate signed by the President or Chief Executive Officer of the Company stating that, in the good faith judgment of the Board of Directors of the Company,
it would be materially detrimental to the Company and its stockholders for such registration statement to be filed and it is therefore essential to defer the filing of such registration statement, then the Company shall have the right to defer such
filing for a period of not more than 120 days following receipt of the request of the Initiating Holders; provided, however, that the Company may not utilize this right more than once in any 12-month period.

 (e) Other Company Shares. If the managing underwriters have not limited the Registrable Securities to be underwritten, the Company
may include securities for its own account or for the account of others in such registration if the managing underwriters so agree and if the number of Registrable Securities which would otherwise have been included in such registration and
underwriting will not thereby be limited. 
 2.2 Company Registration. 

(a) Company Registration. If the Company shall determine to register any of its securities either for its own account or the account of
a security holder or holders, other than a registration pursuant to Section 2.1 or 2.3, a registration relating solely to employee benefit plans, a registration relating to the offer and sale of debt securities, a
registration relating to a corporate reorganization or other Rule 145 transaction, a registration on any registration form that does not permit secondary sales, or a registration for its Initial Public Offering, the Company will: 

(i) promptly give written notice of the proposed registration to all Holders; and 

(ii) use its commercially reasonable efforts to include in such registration (and any related qualification under blue sky laws or other
compliance), except as set forth in Section 2.2(b) below, and in any underwriting involved therein, all of such Registrable Securities as are specified in a written request or requests made by any Holder or Holders received
by the Company within ten (10) days after such written notice from the Company is mailed or delivered. Such written request may specify all or a part of a Holder’s Registrable Securities. 

  
 5 








 (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 as a part of the written notice given pursuant to Section 2.2(a)(i). In such event, the right of any Holder to registration
pursuant to this Section 2.2 shall be conditioned upon such Holder’s participation in such underwriting and the inclusion of such Holder’s Registrable Securities in the underwriting to the extent provided herein.
All Holders proposing to distribute their securities through such underwriting shall (together with the Company and the other holders of securities of the Company with registration rights to participate therein distributing their securities through
such underwriting) enter into an underwriting agreement in customary form with the representative of the underwriter or underwriters selected by the Company. 

Notwithstanding any either provision of this Section 2.2, if the underwriters advise the Company in writing that
marketing factors require a limitation on the number of shares to be underwritten, the underwriters may (subject to the limitations set forth below) exclude all Registrable Securities from, or limit the number of Registrable Securities to be
included in, the registration and underwriting. The Company shall so advise all holders of securities requesting registration, and the number of shares of securities that are entitled to be included in the registration and underwriting shall be
allocated, as follows: (i) first, to the Company for securities being sold for its own account, (ii) second, to the Holders requesting to include Registrable Securities in such registration statement based on the pro rata percentage of
Registrable Securities held by such Holders, and (iii) third, to any stockholders of the Company (other than a Holder) based on the pro rata percentage of capital stock held by such stockholders. 

If a person who has requested inclusion in such registration as provided above does not agree to the terms of any such underwriting, such
person shall also be excluded therefrom by written notice from the Company or the underwriter. The Registrable Securities or other securities so excluded hall also be withdrawn from such registration. Any Registrable Securities or other securities
excluded or withdrawn from such underwriting shall be withdrawn from such registration. 
 (c) Right to Terminate Registration. The
Company shall have the right to terminate or withdraw any registration initiated by it under this Section 2.2 prior to the effectiveness of such registration whether or not any Holder has elected to include securities in
such registration. 
 2.3 Registration on Form S-3. 

(a) Request for Form S-3 Registration. After its initial public offering, the Company shall use
its commercially reasonable efforts to qualify for registration on Form S-3 or any comparable or successor form or forms. After the Company has qualified for the use of Form
S-3, in addition to the rights contained in the foregoing provisions of this Section 2 and subject to the conditions set forth in this Section 2.3, if the
Company shall receive from a Holder or Holders of Registrable Securities a written request that the Company effect any registration on Form S-3 or any similar short form registration statement with respect to
all or part of the Registrable Securities (such request shall state the number of shares of Registrable Securities to be disposed of and the intended methods of disposition of such shares by such Holder or Holders), the Company will:
(i) promptly give written notice of the proposed registration to all other Holders; and (ii) as soon as practicable, file and use its best efforts to effect such registration (including, without limitation, filing post-effective
amendments, appropriate qualifications under applicable blue sky or other state securities laws, and appropriate compliance with the Securities Act) and to permit or 

  
 6 








 
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 twenty (20) days after such written notice from the Company is mailed or delivered. 

(b) Limitations on Form S-3 Registration. The Company shall not be obligated to effect, or take
any action to effect, any such registration pursuant to this Section 2.3: 
 (i) Prior to one hundred eighty
(180) days following the effective date of the first registration statement filed by the Company covering an underwritten offering of any of its securities to the general public (or the subsequent date on which all the market stand-off agreements applicable to the offering have terminated); 
 (ii) 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; 
 (iii) During the period starting with the date ninety (90) days prior to the Company’s good
faith estimate of the date of filing of, and ending on a date one hundred eighty (180) days after the effective date of, a Company-initiated registration (or ending on the subsequent date on which all market
stand-off agreements applicable to the offering have terminated); provided that the Company is actively employing in good faith commercially reasonable efforts to cause such registration statement to
become effective. 
 (iv) If the Holders, together with the holders of any other securities of the Company entitled to inclusion in such
registration, propose to sell Registrable Securities and such other securities (if any) on Form S-3 at an aggregate price to the public of less than $1,000,000; or registration in such period. 

(c) Deferral. If (i) in the good faith judgment of the Board of Directors of the Company, the filing of a registration statement
covering the Registrable Securities would be seriously detrimental to the Company and the Board of Directors of the Company concludes, as a result, that it is in the best interests of the Company to defer the filing of such registration statement at
such time, and (ii) 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 of the Company, it would be seriously detrimental to the
Company for such registration statement to be filed in the near future and that it is, therefore, in the best interests of the Company to defer the filing of such registration statement, then (in addition to the limitations set forth in
Section 2.3(b)(iii) above) the Company shall have the right to defer such filing for a period of not more than one hundred eighty (180) days after receipt of the initial request of a Holder, and, provided further, that
the Company shall not defer its obligation in this manner more than once in any twelve-month period. 
 (d) Underwriting. If the
Holders of Registrable Securities requesting registration under this Section 2.3 intend to distribute the Registrable Securities covered by their request by means of an underwriting, they shall so advise the Company as a
part of their request made 

  
 7 








 
pursuant to this Section 2.3 and the Company shall include such information in’ the written notice given pursuant to Section 2.3(a). In
such event, the right of any Holder to include all or any portion of its Registrable Securities in such registration pursuant to this Section 2.3 shall be conditioned upon such Holder’s participation in such
underwriting and the inclusion of such Holder’s Registrable Securities to the extent provided herein. If the Company shall request inclusion in any registration pursuant to Section 2.3 of securities being sold for its
own account, or if other persons shall request inclusion in any registration pursuant to Section 2.3, the Holders requesting such registration shall, on behalf of all Holders, offer to include such securities in the
underwriting and such offer shall be conditioned upon the participation of the Company or such other persons in such underwriting and the inclusion of the Company’s and such person’s other securities of the Company and their acceptance of
the further applicable provisions of this Section 2 (including Section 2.10). The Company shall (together with all Holders and other persons proposing to distribute their securities through such
underwriting) enter into an underwriting agreement in customary form with the representative of the underwriter or underwriters selected for such underwriting by the Company, which underwriters are reasonably acceptable to a majority in interest of
the Initiating Holders. 
 2.4 Expenses of Registration. All Registration Expenses incurred in connection with registrations
pursuant to Sections 2.2 and 2.3 hereof shall be borne by the Company; provided, however, that the Company shall not be required to pay for any expenses of any registration proceeding begun pursuant to Section 2.3 if
the registration request is subsequently withdrawn at the request of the Holders of a majority of the Registrable Securities to be registered or because a sufficient number of Holders shall have withdrawn so that the minimum offering conditions set
forth in Section 2.3 are no longer satisfied (in which case all participating Holders shall bear such expenses pro rata among each other based on the number of Registrable Securities requested to be so registered). All
Selling Expenses relating to securities registered on behalf of the Holders shall be borne by the holders of securities included in such registration pro rata among each other on the basis of the number of Registrable Securities so registered,
provided, however, that the Company shall pay the reasonable expenses of a single legal counsel to the Holders in an amount not to exceed $15,000 per registration. 

2.5 Registration Procedures. In the case of each registration effected by the Company pursuant to Section 2,
the Company will keep each Holder advised in writing as to the initiation of each registration and as to the completion thereof. At its expense, the Company will use its commercially reasonable efforts to: 

(a) Keep such registration effective for a period of ending on the earlier of the date which is ninety (90) days from the effective date
of the registration statement or such time as the Holder or Holders have completed the distribution described in the registration statement relating thereto; 

(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 Securities Act with respect to the disposition of all securities covered by such registration statement for the period set forth in subsection (a) above;


  
 8 








 (c) Furnish such number of prospectuses, including any preliminary prospectuses, and other
documents incident thereto, including any amendment of or supplement to the prospectus, as a Holder from time to time may reasonably request; 

(d) Use its commercially reasonable efforts to register and qualify the securities covered by such registration statement under such other
securities or Blue Sky laws of such jurisdiction 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; 
 (e) Notify each seller 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 or incomplete in light of the circumstances then existing, and
following such notification promptly prepare and furnish to such seller a reasonable number of copies of a supplement to or an amendment of such prospectus as may be necessary so that, as thereafter delivered to the purchasers of such shares, such
prospectus shall not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading or incomplete in light of the circumstances then existing;

 (f) Provide a transfer agent and registrar for all Registrable Securities registered pursuant to such registration statement and a CUSIP
number for all such Registrable Securities, in each case not later than the effective date of such registration; and 
 (g) Cause all such
Registrable Securities registered pursuant hereunder to be listed on each securities exchange on which similar securities issued by the Company are then listed. 

2.6 Indemnification. 
 (a)
To the extent permitted by law, the Company will indemnify and hold harmless each Holder, each of its officers, directors and partners, legal counsel and accountants 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 2, and each underwriter, if any, and each person who controls within the meaning of
Section 15 of the Securities Act any underwriter, against all expenses, claims, losses, damages and liabilities (or actions, proceedings or settlements in respect thereof) arising out of or based on: (i) any untrue statement (or alleged
untrue statement) of a material fact contained or incorporated by reference in any prospectus, offering circular or other document (including any related registration statement, notification or the like) incident to any such registration,
qualification or compliance, (ii) 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, or (iii) any violation (or alleged violation)
by the Company of the Securities Act, any state securities laws or any rule or regulation thereunder applicable to the Company and relating to action or inaction required of the Company in connection with any offering covered by such registration,
qualification or compliance, and the Company will reimburse each such Holder, each of its officers, directors, partners, legal counsel and accountants 

  
 9 








 
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 and defending or settling any such claim, loss, damage, liability or action; provided that the Company will not be liable in any such case to the extent that any such claim, loss, damage, liability, or action arises out of or is
based on any untrue statement or omission based upon written information furnished to the Company by such Holder, any of such Holder’s officers, directors, partners, legal counsel or accountants, any person controlling such Holder, such
underwriter or any person who controls any such underwriter, and stated to be specifically for use therein; and provided, further that, the indemnity agreement contained in this Section 2.6(a) shall not apply to
amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without the consent of the Company (which consent shall not be unreasonably withheld). 

(b) To the extent permitted by law, each Holder 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 and hold harmless the Company, each of its directors, officers, partners, legal counsel and accountants and 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, each other such Holder, and each of their officers, directors and partners, and each
person controlling each other such Holder, against all claims, losses, damages and liabilities (or actions in respect thereof) arising out of or based on: (i) any untrue statement (or alleged untrue statement) of a material fact contained or
incorporated by reference in any prospectus, offering circular or other document (including any related registration statement, notification, or the like) incident to any such registration, qualification or compliance, or (ii) 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 and such Holders, directors, officers, partners, legal counsel and
accountants, persons, underwriters, or control persons for any legal or any other expenses reasonably incurred in connection with investigating or defending any such claim, loss, damage, liability or action, in each case to the extent, but only 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 such Holder and stated to be specifically for use therein; provided, however, that the obligations of such Holder hereunder shall not apply to amounts paid in settlement of any such claims,
losses, damages or liabilities (or actions in respect thereof) if such settlement is effected without the consent of such Holder (which consent shall not be unreasonably withheld); and provided that in no event shall any indemnity under this
Section 2.6 exceed the gross proceeds from the offering received by such Holder, except in the case of fraud or willful misconduct by such Holder. 

(c) Each party entitled to indemnification under this Section 2.6 (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 such claim or any litigation resulting therefrom; provided that counsel for the Indemnifying Party, who shall conduct the defense of such claim or any litigation resulting therefrom, shall be approved by the
Indemnified Party (whose approval shall not be unreasonably withheld), and the Indemnified Party may participate in such defense at such party’s expense; and provided further that the failure


  
 10 








 
of any Indemnified Party to give notice as provided herein shall not relieve the Indemnifying Party of its obligations under is Section 2.6, to the extent such failure
is not prejudicial. 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 that 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. Each Indemnified Party shall furnish such information regarding itself or the claim
in question as an Indemnifying Party may reasonably request in writing and as shall be reasonably required in connection with defense of such claim and litigation resulting therefrom. 

(d) If the indemnification provided for in this Section 2.6 is held by a court of competent jurisdiction to be
unavailable to an Indemnified Party with respect to any loss, liability, claim, damage, or expense referred to herein, then the Indemnifying Party, in lieu of indemnifying such Indemnified Party hereunder, shall contribute to the amount paid or
payable by such Indemnified Party as a result of such loss, liability, claim, damage, or expense 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
in connection with the statements or omissions that resulted in such loss, liability, claim, damage, or expense as well as any other relevant equitable considerations. 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. No person or entity guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) will be entitled to contribution from any person or entity who was not guilty of such fraudulent misrepresentation. 
 (e)
Notwithstanding the foregoing, to the extent that the provisions on indemnification and contribution contained in the underwriting agreement entered into in connection with the underwritten public offering are in conflict with the foregoing
provisions, the provisions in the underwriting agreement shall control. 
 2.7 Information by Holder. Each Holder of
Registrable Securities shall furnish to the Company such information regarding such Holder and the distribution proposed by such Holder as the Company may reasonably request in writing and as shall be reasonably required in connection with any
registration, qualification, or compliance referred to in this Section 2. 
 2.8 Restrictions on Transfer.

 (a) The holder of each certificate representing Registrable Securities by acceptance thereof agrees to comply in all respects with the
provisions of this Section 2.8. Each Holder agrees not to make any sale, assignment, transfer, pledge or other disposition of all or any portion of the Restricted Securities, or any beneficial interest therein,
unless and until (x) the transferee thereof has agreed in writing for the benefit of the Company to take and hold such Restricted Securities subject to, and to be bound by, the terms and conditions set forth in this Agreement, including,
without limitation, this Section 2.8 and Section 2.10, except for transfers permitted under Section 2.8(b), and (y): 

(i) There is then in effect a registration statement under the Securities Act covering such proposed disposition and such disposition is made
