REGISTRATION RIGHTS 

Section 2.01 Mandatory Registration. 

(a) No later than 15 days following the closing under the Common Stock Subscription Agreement (the “Filing Deadline”), the
Company shall prepare and file a registration statement with the Commission providing for registration and resale from time to time, on a continuous or delayed basis pursuant to Rule 415, of all of the Registrable Securities then outstanding; such
registration statement shall be on Form S-1 (or any equivalent or successor form) under the Securities Act (or if the Company is eligible to use Form S-3 or any
equivalent or successor form or forms, on Form S-3 or any comparable or successor form, and, if the Company is a “well-known seasoned issuer” as of the filing date, an “automatic shelf
registration statement” (as those terms are defined under Rule 405 promulgated under the Securities Act)); provided, however, that if the Company has filed the registration statement on Form S-1
and subsequently becomes eligible to use Form S-3 or any equivalent or successor form or forms, the Company may elect, in its sole discretion, to (i) file a post-effective amendment to the registration
statement converting such registration statement on Form S-1 to a registration statement on Form S-3 or any equivalent or successor form or forms or (ii) withdraw
the registration statement on Form S-1 and file a registration statement on Form S-3 or any equivalent or successor form or forms (the registration statement on such
form, as amended or supplemented, or any subsequent registration statement, the “Registration Statement”). The Company shall use its commercially reasonable efforts to cause the Registration Statement to be


  
 3 








 
declared effective under the Securities Act by the Commission as soon as reasonably practicable after the Filing Deadline and no later than 60 days following the filing of the Registration
Statement (or, if earlier, five Business Days after being advised by the staff of the Commission that it will not review, or will not further review, the Registration Statement) (the “Effectiveness Deadline”). Subject to
Section 2.03, the Company shall use its commercially reasonable efforts to keep the Registration Statement continuously effective under the Securities Act from the time the Commission declares it effective until the earlier
of the date on which (A) all of the Registrable Securities covered by such Registration Statement have been sold and (B) all of the shares of Common Stock purchased pursuant to the Common Stock Subscription Agreement cease to be
Registrable Securities hereunder (such period, the “Effectiveness Period”). The Registration Statement when effective (including the documents incorporated therein by reference) will comply as to form in all material respects with
all applicable requirements of the Securities Act and the Exchange Act and will not contain 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 (in the case of any prospectus contained in such Registration Statement, in the light of the circumstances under which a statement is made). As soon as practicable following the date that the Registration Statement becomes effective, but
in any event within one Business Day of such date, the Company shall provide the Holders with written notice of the effectiveness of such Registration Statement. 

(b) Each Holder (other than any initial Purchaser of Common Stock under the Common Stock Subscription Agreement) that provides a completed
Notice and Questionnaire to the Company agrees that, if such Holder wishes to sell Registrable Securities pursuant to the Registration Statement and related prospectus, it will do so only in accordance with this
Section 2.01(b). Each such Holder wishing to sell Registrable Securities pursuant to the Registration Statement and related prospectus agrees to deliver a Notice and Questionnaire to the Company at least 15 Business Days
prior to any intended distribution of Registrable Securities under the Registration Statement. From and after the date the Registration Statement is declared effective, the Company shall, as promptly as practicable after the date a Notice and
Questionnaire is delivered to it, and in any event by the later of (x) 15 Business Days after such date, (y) ten Business Days after effectiveness or (z) if a Blackout and Delay Event is in effect when, or is put into effect within five
Business Days after, the Notice and Questionnaire is delivered, 15 Business Days after the expiration of such Blackout and Delay Event: 

(i) if required by applicable law, file with the Commission a post-effective amendment to the Registration Statement or prepare
and, if required by applicable law, file a prospectus or a supplement to the related prospectus or a supplement or amendment to any document incorporated therein by reference or file any other required document so that the Holder delivering such
Notice and Questionnaire is named as a selling security holder in the Registration Statement and the related prospectus in such a manner as to permit such Holder to deliver such prospectus to purchasers of Registrable Securities in accordance with
applicable law and, if the Company shall file a post-effective amendment to the Registration Statement, use its commercially reasonable efforts to cause such post-effective amendment to be declared effective under the Securities Act as promptly as
is practicable, but in any event by the date that is 90 days after the date such post-effective amendment is required by this clause to be filed; 

  
 4 








 (ii) provide such Holder copies of any documents filed pursuant to
Section 2.01(b)(i); and 
 (iii) notify such Holder as promptly as practicable after the
effectiveness under the Securities Act of any post-effective amendment filed pursuant to Section 2.01(b)(i); 
 provided
that if such Notice and Questionnaire is delivered during a Blackout and Delay Event, the Company shall so inform the Holder delivering such Notice and Questionnaire and shall not be obligated to take the actions set forth in clauses (i), (ii) and
(iii) until the expiration of the Blackout and Delay Event in accordance with Section 2.03. 

Section 2.02 Failure to Obtain and Maintain Effectiveness; Liquidated Damages. 

(a) If (i) the Company has not filed the Registration Statement with the Commission on or prior to the Filing Deadline or the Registration
Statement is not declared effective by the Commission on or prior to the Effectiveness Deadline (in each case, other than due to the inaccuracy or omission of any information relating to any Holder provided in writing or required to be provided by
or on behalf of a Holder to the Company for inclusion in the Registration Statement), (ii) during the Effectiveness Period, the Registration Statement ceases to be effective or the Holders are otherwise not permitted to resell Registrable
Securities pursuant to the Registration Statement for more than an aggregate of 45 days (which need not be consecutive days) in any 90-day period or more than an aggregate of 105 days (which need not be
consecutive days) in any 365-day period (other than (A) due to the inaccuracy or omission of any information relating to any Holder provided in writing or required to be provided by or on behalf of a
Holder to the Company for inclusion in the Registration Statement or (B) for a period of up to 90 days following the filing of a post-effective amendment or in connection with conversion from
Form S-1 to Form S-3), or (iii) the Company fails to satisfy the current public information requirement pursuant to Rule 144(c)(1) as a result of which the
Holders are unable to sell Registrable Securities without restriction under Rule 144 (any such failure or breach, an “Event” and the date of any Event, an “Event Date”), then each Holder shall be entitled to a
payment, as liquidated damages and not as a penalty, in an amount equal to 0.25% of such Holder’s Liquidated Damages Base per 30-day period, which amount shall accrue daily, for the first 30 days
following the applicable Event Date, increasing by an additional 0.25% of such Holder’s Liquidated Damages Base for each subsequent 30-day period, up to a maximum of 1.0% of such Holder’s Liquidated
Damages Base per 30-day period (i.e. 0.50% for the period of 31-60 days following the applicable Event Date, 0.75% for the period of
61-90 days following the applicable Event Date and 1.0% for each 30-day period thereafter) (the “Liquidated Damages”), subject to the maximum aggregate
limitations in Section 2.02(b). Liquidated Damages payable to a Holder shall cease to accrue when the Event is cured or the Holder no longer owns Registrable Securities, whichever is earlier, and shall be prorated in the
event Liquidated Damages cease to accrue prior to the end of the applicable 30-day calculation period. 

(b) The parties agree that the maximum aggregate Liquidated Damages payable to a Holder shall be 5% of such Holder’s Liquidated Damages
Base, regardless of the number of Events that occur, provided that the maximum aggregate Liquidated Damages payable to a Holder shall be 10% of such Holder’s Liquidated Damages Base to the extent the excess over 5% of the Holder’s
Liquidated Damages Base is due to an Event or Events under clause (iii) of Section 2.02(a). 

  
 5 








 (c) Liquidated Damages shall be paid to each Holder in immediately available funds within ten
Business Days of the end of each applicable 30-day calculation period following an Event Date, or such shorter period of time if the applicable Event is cured before the end of any 30-day calculation period. Any Liquidated Damages due under this Section 2.02 shall constitute the Holders’ exclusive remedy for such events. 

Section 2.03 Blackout and Delay Events. Notwithstanding anything to the contrary contained herein: 

(a) the Company shall not be required to file a Registration Statement (or any amendment thereto) or, if a Registration Statement has been
filed but not declared effective by the Commission, request effectiveness of such Registration Statement, for a period of up to 45 days, if (A) the Company determines in good faith that a postponement is in the best interest of the Company and
its stockholders generally due to a pending transaction involving the Company (including a pending securities offering by the Company, or any proposed financing, acquisition, merger, tender offer, business combination, corporate reorganization,
consolidation or other significant transaction involving the Company), (B) the Company determines such registration would render the Company unable to comply with applicable securities laws, (C) the Company determines such registration
would require disclosure of material information that the Company has a bona fide business purpose for preserving as confidential, or (D) audited financial statements as of a date other than the fiscal year end of the Company would be required
to be prepared; provided, however, that in no event shall any such period exceed an aggregate of 90 days in any 365-day period; and 

(b) the Company may, upon written notice to any Selling Holder whose Registrable Securities are included in the Registration Statement (which
notice shall not contain any material, non-public information regarding the Company), suspend such Selling Holder’s use of any prospectus which is a part of the Registration Statement (in which event the
Selling Holder shall discontinue sales of the Registrable Securities pursuant to the Registration Statement but may settle any previously made sales of Registrable Securities) if (i) the Company determines that it would be required to make
disclosure of material information in the Registration Statement that the Company has a bona fide business purpose for preserving as confidential or (ii) the Company has experienced some other material
non-public event the disclosure of which at such time, in the good faith judgment of the Company, would adversely affect the Company; provided, however, in no event shall the Selling Holders be
suspended from selling Registrable Securities pursuant to the Registration Statement for a period that exceeds an aggregate of 60 days (which need not be consecutive days) in any 180-day period or 105 days
(which need not be consecutive days) in any 365-day period. Upon disclosure of such information or the termination of the condition described above, the Company shall provide prompt notice to the Selling
Holders whose Registrable Securities are included in the Registration Statement, and shall promptly terminate any suspension of sales it has put into effect and shall take such other reasonable actions to permit registered sales of Registrable
Securities as contemplated in this Agreement.

 Section 2.04 Sale Procedures. 

(a) In connection with its obligations under this Article II, the Company will, as expeditiously as possible: 

(i) prepare and file with the Commission such amendments and supplements to the Registration Statement and the prospectus used
in connection therewith as may be necessary to keep the Registration Statement effective for the Effectiveness Period and as may be necessary to comply with the provisions of the Securities Act with respect to the disposition of all Registrable
Securities covered by the Registration Statement; 
 (ii) make available to each Selling Holder (x) as far in advance as
reasonably practicable before filing the Registration Statement or any supplement or amendment thereto, upon request, copies of reasonably complete drafts of all such documents proposed to be filed (including exhibits and each document incorporated

is contained therein and make the corrections reasonably requested by such Selling Holder with respect to such information prior to filing the Registration Statement or supplement or amendment thereto, and (y) such number of copies of the
Registration Statement and the prospectus included therein and any supplements and amendments thereto as such Selling Holder may reasonably request in order to facilitate the public sale or other disposition of the Registrable Securities covered by
such Registration Statement; 
 (iii) if applicable, use its commercially reasonable efforts to register or qualify the
Registrable Securities covered by the Registration Statement under the securities or blue sky laws of such jurisdictions as the Selling Holders shall reasonably request in writing by the time the Registration Statement is declared effective by the
Commission; provided, however, that the Company will not be required to qualify generally to transact business in any jurisdiction where it is not then required to so qualify or to take any action that would subject it to general service of
process in any such jurisdiction where it is not then so subject; 
 (iv) promptly notify each Selling Holder, at any time
when a prospectus relating thereto is required to be delivered by any of them under the Securities Act (which notice shall not contain any material, non-public information regarding the Company), of
(x) the filing of the Registration Statement or any prospectus or prospectus supplement to be used in connection therewith, or any amendment or supplement thereto, and, with respect to such Registration Statement or any post-effective amendment
thereto, when the same has become effective; and (y) the receipt of any written comments from the Commission with respect to any filing referred to in clause (x) and any written request by the Commission for amendments or supplements to
the Registration Statement or any prospectus or prospectus supplement thereto; 

  
 7 








 (v) immediately notify each Selling Holder (which notice shall not contain any
material, non-public information regarding the Company), at any time when a prospectus relating thereto is required to be delivered under the Securities Act, of (x) the happening of any event as a result
of which the prospectus or prospectus supplement contained in the Registration Statement, as then in effect, includes an untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to make the
statements therein not misleading (in the case of any prospectus contained therein, in the light of the circumstances under which a statement is made); (y) the issuance or express threat of issuance by the Commission of any stop order suspending the
effectiveness of the Registration Statement or the initiation of any proceedings for that purpose; or (z) the receipt by the Company of any notification with respect to the suspension of the qualification of any Registrable Securities for sale
under the applicable securities or blue sky laws of any jurisdiction. Following the occurrence of any of the events set forth in clauses (x) through (z) above, the Company agrees to as promptly as practicable amend or supplement the prospectus
or prospectus supplement or take other appropriate action so that the prospectus or prospectus supplement does 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 in the light of the circumstances then existing and to take such other commercially reasonable action as is necessary to remove a stop order, suspension, threat thereof or proceedings related thereto; 

(vi) upon request and subject to appropriate confidentiality obligations, furnish to each Selling Holder copies of any and all
transmittal letters or other correspondence with the Commission or any other governmental agency or self-regulatory body or other body having jurisdiction (including any domestic or foreign securities exchange) relating to the Registration
Statement; 
 (vii) otherwise use its commercially reasonable efforts to comply with all applicable rules and regulations of
the Commission, and make available to its security Holders, as soon as reasonably practicable, an earnings statement, which earnings statement shall satisfy the provisions of Section 11(a) of the Securities Act and Rule 158 promulgated
thereunder; 
 (viii) cause all such Registrable Securities registered pursuant to this Agreement to be listed on the NYSE;

 8 








 (x) if requested by a Selling Holder, (x) incorporate in a prospectus
supplement or post-effective amendment such information as such Selling Holder reasonably requests to be included therein relating to the sale and distribution of Registrable Securities, including information with respect to the number of
Registrable Securities being offered or sold, the purchase price being paid therefor and any other terms of the offering of the Registrable Securities to be sold in such offering and (y) make all required filings of such prospectus supplement

Statement without such Holder’s consent. If the staff of the Commission requires the Company to name any Holder as an underwriter as defined in Section 2(a)(11) of the Securities Act, and such Holder does not consent thereto, then such
Holder’s Registrable Securities shall not be included on the Registration Statement and the Company shall have no further obligations hereunder with respect to Registrable Securities held by such Holder. 

(c) Each Selling Holder, upon receipt of notice from the Company of the happening of any event of the kind described in subsection

Registrable Securities by means of a prospectus or prospectus supplement until such Selling Holder’s receipt of the copies of the supplemented or amended prospectus contemplated by subsection (v) of
Section 2.04(a) or until it is advised in writing by the Company that the use of the prospectus may be resumed and has received copies of any additional or supplemental filings incorporated by reference in the prospectus,
and, if so directed by the Company, such Selling Holder will deliver to the Company (at the Company’s expense) all copies in their possession or control, other than permanent file copies then in such Selling Holder’s possession, of the
prospectus covering such Registrable Securities current at the time of receipt of such notice. 
 Section 2.05 Cooperation by
Holders. The Company shall have no obligation to include in the Registration Statement Registrable Securities of a Holder who has failed to timely furnish such information that the Company determines, after consultation with its counsel, is
reasonably required in order for the registration statement or prospectus supplement, as applicable, to comply with the Securities Act. 

Section 2.06 Expenses. The Company will pay all reasonable Registration Expenses as determined in good faith. Except as otherwise
provided in this Section 2.06 or in Section 2.07, the Company shall not be responsible for legal fees incurred by Holders in connection with the exercise of such Holders’ rights hereunder.

 Section 2.07 Indemnification. 

(a) Indemnification by the Company. In the event of any registration of any securities of the Company under the Securities Act pursuant
to this Agreement, the Company will, and hereby does, indemnify and hold harmless the seller of any Registrable Securities covered by such registration statement, its directors, officers, partners, members, employees, investment advisers and agents,
each other Person who participates in the offering or sale of such securities, each other Person, if any, who controls such seller, within the meaning of the Securities Act, and the directors, officers, partners, members, employees, investment
advisers and agents of such controlling person against any losses, claims, damages or liabilities, joint or several, to which such seller or any such director or officer or controlling person may become subject, under the Securities Act or
otherwise, insofar as such losses, claims, damages or liabilities (or actions or proceedings, whether commenced or threatened, in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact
contained in any registration statement under which such securities were registered under the Securities Act, any preliminary prospectus, final prospectus or summary prospectus contained therein, or any amendment or supplement thereto, 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 the Company will reimburse such seller and each such director, officer and controlling person
for any legal or any other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, liability, action or proceeding; provided that the Company shall not be liable in any such case to the extent
that any such loss, claim, damage, liability (or action or proceeding in respect thereof) or expense arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in such registration statement,
any such preliminary prospectus, final prospectus, summary prospectus, amendment or supplement in reliance upon and in conformity with information furnished by such seller to the Company in writing or electronically for use in the preparation
thereof. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of such seller or any such director, officer or controlling person and shall survive the transfer of such securities by such seller.

 (b) Indemnification by the Sellers. The Company may require, as a condition to including any Registrable Securities in any
registration statement filed pursuant to Section 2.01, that the Company shall have received an undertaking satisfactory to it from the prospective seller of such securities to indemnify and hold harmless (in the same manner
and to the same extent as set forth in Section 2.07(a)) the Company, each director of the Company, each officer of the Company and each other Person, if any, who controls the Company within the meaning of the Securities
Act, with respect to any statement or alleged statement in or omission or alleged omission from such registration statement, any preliminary prospectus, final prospectus or summary prospectus contained therein, or any amendment or supplement
thereto, if such statement or alleged statement or omission or alleged omission was made in reliance upon and in conformity with information furnished by such seller to the Company in writing or electronically for use in the preparation of such
registration statement, preliminary prospectus, final prospectus, 

  
 10 








 
summary prospectus, amendment or supplement. The maximum liability of each seller for any such indemnification shall not exceed the amount of net proceeds received by such seller from the sale of
such seller’s Registrable Securities. Such indemnity shall remain in full force and effect, regardless of any investigation made by or on behalf of the Company or any such director, officer or controlling Person and shall survive the transfer
of such securities by such seller. 
 (c) Notices of Claims, etc. Promptly after receipt by an indemnified party of notice of the
commencement of any action or proceeding involving a claim referred to in Section 2.07(a) or (b), such indemnified party will, if a claim in respect thereof is to be made against an indemnifying party, give written
notice to the latter of the commencement of such action; provided that the failure of any indemnified party to give notice as provided herein shall not relieve the indemnifying party of its obligations under
Section 2.07(a) or (b), except to the extent that the indemnifying party is actually prejudiced by such failure to give notice. In case any such action is brought against an indemnified party, unless in such
indemnified party’s reasonable judgment a conflict of interest between such indemnified and indemnifying parties may exist in respect of such claim, the indemnifying party shall be entitled to participate in and to assume the defense thereof,
jointly with any other indemnifying party similarly notified to the extent that it may wish, with counsel reasonably satisfactory to such indemnified party, and after notice from the indemnifying party to such indemnified party of its election so to
assume the defense thereof, the indemnifying party shall not be liable to such indemnified party for any legal or other expenses subsequently incurred by the latter in connection with the defense thereof other than reasonable costs of investigation.
No indemnifying party shall, without the consent of the 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) Other Indemnification.
Indemnification similar to that specified in Sections 2.07(a), (b) and (c) (with appropriate modifications) shall be given by the Company and each seller of Registrable Securities with respect to any required registration or
other qualification of securities under any federal or state law or regulation of any governmental authority other than the Securities Act. 

(e) Indemnification Payments. The indemnification required by this Section 2.07 shall be made by periodic
payments of the amount thereof during the course of the investigation or defense, as and when bills are received or expense, loss, damage or liability is incurred. 

Section 2.08 Rule 144 Reporting. With a view to making available the benefits of certain rules and regulations of the Commission
that may permit the sale of the Registrable Securities to the public without registration, the Company agrees to use its commercially reasonable efforts to:

at all times from and after the date hereof; 

  
 11 








 (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 all times from and after the date hereof; and 
 (c) so long as a Holder owns any

reasonably request in availing itself of any rule or regulation of the Commission allowing such Holder to sell any such securities without registration. 

Section 2.09 Transfer or Assignment of Registration Rights. The rights to cause the Company to register Registrable Securities
granted to the Purchasers by the Company under this Article II may be transferred or assigned by any Purchaser to one or more transferees or assignees of Registrable Securities; provided, however, that (a) unless the transferee or
assignee is an Affiliate of, and after such transfer or assignment continues to be an Affiliate of, such Purchaser, the amount of Registrable Securities transferred or assigned to such transferee or assignee shall represent at least $25 million
of Registrable Securities (based on the Common Stock Price) or, if less, 100% of the Registrable Securities then held by such Purchaser, (b) the Company is given written notice prior to any said transfer or assignment, stating the name and
address of each such transferee or assignee and identifying the securities with respect to which such registration rights are being transferred or assigned, and (c) each such transferee or assignee assumes in writing responsibility for its
portion of the obligations of such Purchaser under this Agreement.

 Section 3.03
Assignment of Rights. All or any portion of the rights and obligations of any Purchaser under this Agreement may be transferred or assigned by such Purchaser only in accordance with Section 2.09. 

Section 3.04 Recapitalization, Exchanges, Etc. Affecting the Shares. The provisions of this Agreement shall apply to the
full extent set forth herein with respect to any and all shares of the Company or any successor or assign of the Company (whether by merger, consolidation, sale of assets or otherwise) that may be issued in respect of, in exchange for or in

REPRESENTATION OR WARRANTY MADE IN OR IN CONNECTION WITH THIS AGREEMENT), WILL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF DELAWARE WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF LAWS. ANY ACTION AGAINST ANY PARTY RELATING

JURISDICTION OF ANY FEDERAL OR STATE COURT LOCATED WITHIN THE STATE OF DELAWARE OVER ANY SUCH ACTION. THE PARTIES HEREBY IRREVOCABLY WAIVE, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY OBJECTION THAT THEY MAY NOW OR HEREAFTER HAVE TO THE
LAYING OF VENUE OF ANY SUCH DISPUTE BROUGHT IN SUCH COURT OR ANY DEFENSE OF INCONVENIENT FORUM FOR THE MAINTENANCE OF SUCH DISPUTE. EACH OF THE PARTIES HERETO AGREES THAT A JUDGMENT IN ANY SUCH DISPUTE MAY BE ENFORCED IN OTHER JURISDICTIONS BY SUIT

 Section 3.10 Severability of Provisions. Any provision of this
Agreement which is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof or affecting or impairing

 Section 3.11 Entire Agreement. This Agreement and
the Common Stock Subscription Agreement are intended by the parties as a final expression of their agreement and intended to be a complete and exclusive statement of the agreement and understanding of the parties hereto in respect of the subject

 Section 3.14 Obligations Limited to Parties to Agreement. Each of the parties hereto
covenants, agrees and acknowledges that no Person other than the Purchasers (and their permitted transferees and assignees) and the Company shall have any obligation hereunder and that, notwithstanding that one or more of the Purchasers may be a
corporation, partnership or limited liability company, no recourse under this Agreement or under any documents or instruments delivered in connection herewith or therewith shall be had against any former, current or future director, officer,
employee, agent, general or limited partner, manager, member, stockholder or Affiliate of any of the Purchasers or any former, current or future director, officer, employee, agent, general or limited partner, manager, member, stockholder or
Affiliate of any of the foregoing, whether by the enforcement of any assessment or by any legal or equitable proceeding, or by virtue of any applicable law, it being expressly agreed and acknowledged that no personal liability whatsoever shall
attach to, be imposed on or otherwise be incurred by any former, current or future director, officer, employee, agent, general or limited partner, manager, member, stockholder or Affiliate of any of the Purchasers or any former, current or future
director, officer, employee, agent, general or limited partner, manager, member, stockholder or Affiliate of any of the foregoing, as such, for any obligations of the Purchasers under this Agreement or any documents or instruments delivered in
connection herewith or therewith or for any claim based on, in respect of or by reason of such obligation or its creation, except in each case for any transferee or assignee of a Purchaser hereunder. 

Section 3.15 Independent Nature of Purchaser’s Obligations. The obligations of each Purchaser under this
Agreement are several and not joint with the obligations of any other Purchaser, and no Purchaser shall be responsible in any way for the performance of the obligations of any other Purchaser under this Agreement. Nothing contained herein, and no
action taken by any Purchaser pursuant thereto, shall be deemed to constitute the Purchasers as a partnership, an association, a joint venture or any other kind of group or entity, or create a presumption that the Purchasers are in any way acting in
concert or as a group with respect to such obligations or the transactions contemplated by this Agreement. Each Purchaser acknowledges that no other Purchaser has acted as agent for such Purchaser in connection with this Agreement and that no
Purchaser will be acting as agent of such Purchaser in connection with enforcing its rights under this Agreement. Each Purchaser shall be entitled to independently protect and enforce its rights, including without limitation, the rights arising out
of this Agreement, and it shall not be necessary for any other Purchaser to be joined as an additional party in any proceeding for such purpose. The failure or waiver of performance by any Purchaser does not excuse performance by any other
Purchaser. It is expressly understood and agreed that each provision contained in this Agreement is between the Company and a Purchaser, solely, and not between the Company and the Purchasers collectively and not between and among the Purchasers.

 Section 3.16 Interpretation. Unless otherwise specified, references to Articles, Sections and Annexes are to Articles,
Sections and Annexes of this Agreement. All references to instruments, documents, contracts and agreements are references to such instruments, documents, contracts and agreements as the same may be amended, supplemented and otherwise modified from
time to time, unless otherwise specified. The word “including” shall mean “including but not limited to.” Whenever any determination, consent or approval is to be made or given by a Purchaser under this Agreement, such action
shall be in such Purchaser’s sole discretion unless otherwise specified. 

  
 15 








 Section 3.17 Effectiveness; Termination. This Agreement shall not be effective, and
no party hereto shall have any obligations hereunder, unless and until the closing under the Common Stock Subscription Agreement shall have occurred. This Agreement shall automatically terminate upon termination of the Common Stock Subscription
Agreement.

Securities are sold through Underwriters, broker-dealers or agents, the Selling Holder will be responsible for underwriting discounts or commissions or agents’ commissions in accordance with the Registration Rights Agreement. Such Registrable
Securities may be sold in one or more transactions at fixed prices, at prevailing market prices at the time of sale, at varying prices determined at the time of sale or at negotiated prices. Such sales may be effected in transactions (which may
involve block transactions) (i) on any national securities exchange or quotation service on which the Registrable Securities may be listed or quoted at the time of sale, (ii) in the over-the-counter market, (iii) in transactions otherwise than on such exchanges or services or in the over-the-counter
market. The Selling Holder may pledge or grant a security interest in some or all of the Registrable Securities owned by it and, if it defaults in the performance of its security obligations, the pledgees or secured parties may offer and sell the
Registrable Securities from time to time pursuant to the prospectus. The Selling Holder also may transfer and donate the Registrable Securities in other circumstances in which case the transferees, donees, pledgees or other successors in interest
will be the Selling Holder for purposes of this prospectus. 
 State any exceptions here:
