 2.1
Demand Registration.

Release Date, and from time to time thereafter, the holders of a majority-in-interest of the Registrable Securities, on an as-converted to Common Stock basis, held by the Investors or the permitted transferees of the Investors, may make a written
demand for registration under the Securities Act of all or part of their Registrable Securities (a “Demand Registration”); provided, that any Registration Statement filed with the Commission with respect to a Demand Registration shall not
be declared effective before the applicable Release Date. Any demand for a Demand Registration shall specify the number of Registrable Securities proposed to be sold and the intended method(s) of distribution thereof. The Company will notify all
holders of Registrable Securities of the demand, and each holder of Registrable Securities who wishes to include all or a portion of such holder’s Registrable Securities in the Demand Registration (each such holder including Registrable
Securities in such registration, a “Demanding Holder”) shall so notify the Company in writing within ten (10) days after the 

  

 3 








 
receipt by the holder of the notice from the Company. Upon any such request, the Demanding Holders shall be entitled to have their Registrable Securities
included in the Demand Registration, subject to Sections 2.1.3, 2.1.4, 3.4 and the provisos set forth in Section 3.1.1. The Company shall not be obligated to effect more than an aggregate of two (2) Demand Registrations under this
Section 2.1.1 in respect of Registrable Securities. 
 2.1.2 Effective Registration. A registration will not count as a Demand
Registration until the Registration Statement filed with the Commission with respect to such Demand Registration has been declared effective and the Company has complied with all of its material obligations under this Agreement with respect thereto;
provided, however, that if, after such Registration Statement has been declared effective, the offering of Registrable Securities pursuant to a Demand Registration is interfered with by any stop order or injunction of the Commission or any other
governmental agency or court, the Registration Statement with respect to such Demand Registration will be deemed not to have been declared effective unless and until such stop order or injunction is removed, rescinded or otherwise terminated;
provided, further, that the Company shall not be obligated to file a second Registration Statement until a Registration Statement that has been filed is counted as a Demand Registration or is terminated. 
 2.1.3 Underwritten Offering. If a majority-in-interest, on an as-converted to Common Stock basis, of the Demanding Holders so elects and such
holders so advise the Company as part of their written demand for a Demand Registration, the offering of such Registrable Securities pursuant to such Demand Registration shall be in the form of an underwritten offering. In such event, the right of
any holder to include its 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 to the extent
provided herein. All Demanding Holders proposing to distribute their securities through such underwriting shall enter into an underwriting agreement in customary form with the Underwriter or Underwriters selected for such underwriting by a
majority-in-interest, on an as-converted to Common Stock basis, of the Demanding Holders, which Underwriter or Underwriters shall be reasonably acceptable to the Company. 
 2.1.4 Reduction of Offering. If the managing Underwriter or Underwriters for a Demand Registration that is to be an underwritten offering advises
the Company and the Demanding Holders in writing that the dollar amount or amount of Registrable Securities which the Demanding Holders desire to sell, taken together with all other shares of Common Stock or other securities which the Company
desires to sell and the shares of Common Stock or other securities, if any, as to which registration has been requested pursuant to written contractual piggy-back registration rights held by other stockholders of the Company who desire to sell,
exceeds the maximum dollar amount or maximum number of securities that can be sold in such offering without adversely affecting the proposed offering price, the timing, the distribution method, or the probability of success of such offering (such
maximum dollar amount or maximum number of securities, as applicable, the “Maximum Number of Securities”), then the Company shall include in such registration: (i) first, the Registrable Securities as to which Demand Registration has
been requested by the Demanding Holders (pro rata in accordance with the number of shares that each such Person has requested be included in such registration, regardless of the number of shares held by each such Person (such proportion is referred
to herein as “Pro Rata”)) that can be sold without exceeding the Maximum Number of Securities; (ii) second, to the extent that the Maximum Number of Securities has not been reached under the foregoing clause (i), the shares of Common
Stock or other securities that the Company desires to sell that can be sold without exceeding the Maximum Number of Securities; and (iii) third, to the extent that the Maximum Number of Securities has not been reached under the foregoing
clauses (i) and (ii), the shares of Common Stock or other securities for the account of other Persons that the Company is obligated to register pursuant to written contractual arrangements with such Persons and that can be sold without
exceeding the Maximum Number of Securities. 
  

 4 








 2.1.5 Withdrawal. If a majority-in-interest, on an as-converted to Common Stock basis, of the
Demanding Holders disapproves of the terms of any underwriting or are not entitled to include all of their Registrable Securities in any offering, such majority-in-interest of the Demanding Holders may elect to withdraw from such offering by giving
written notice to the Company and the Underwriter or Underwriters of their request to withdraw prior to the effectiveness of the Registration Statement filed with the Commission with respect to such Demand Registration. 
 2.1.6 Permitted Delays. The Company shall be entitled to postpone the filing of any Registration Statement under this Section 2.1 if
(a) at any time prior to the filing of such Registration Statement the Board determines, in its good faith business judgment, that such registration and offering would materially and adversely affect any financing, acquisition, corporate
reorganization, or other material transaction involving the Company, and (b) the Company delivers to the Demanding Holders written notice thereof within ten (10) business days of the date of receipt of such request for Demand Registration;
provided that all such periods of postponement may not exceed 45 days during any 365-day period. 
 2.2 Piggy-Back Registration.

 2.2.1 Piggy-Back Rights. If at any time after the applicable Release Date, the Company proposes to file a Registration Statement
under the Securities Act with respect to an offering of equity securities, or securities or other obligations exercisable or exchangeable for, or convertible into, equity securities, by the Company for its own account and/or for stockholders of the
Company for their account, then the Company shall (x) give written notice of such filing to the holders of Registrable Securities, which notice shall describe the amount and type of securities to be included in such offering, the intended
method(s) of distribution, and the name of the proposed managing Underwriter or Underwriters, if any, of the offering, and (y) offer to the holders of Registrable Securities in such notice the opportunity to register the sale of such number of
Registrable Securities as such holders may request in writing within five (5) days following receipt of such notice (a “Piggy-Back Registration”). The Company shall cause such Registrable Securities to be included in such registration
and shall use reasonable efforts to cause the managing Underwriter or Underwriters of a proposed underwritten offering to permit the Registrable Securities requested to be included in a Piggy-Back Registration on the same terms and conditions as any
similar securities of the Company and to permit the sale or other disposition of such Registrable Securities in accordance with the intended method(s) of distribution thereof. All holders of Registrable Securities proposing to distribute their
securities through a Piggy-Back Registration that involves an Underwriter or Underwriters shall enter into an underwriting agreement in customary form with the Underwriter or Underwriters selected for such Piggy-Back Registration. 
 2.2.2 Reduction of Offering. If the managing Underwriter or Underwriters for a Piggy-Back Registration that is to be an underwritten offering
advises the Company and the holders of Registrable Securities in writing that the dollar amount or number of shares of Common Stock or other securities which the Company desires to sell, taken together with shares of Common Stock or other
securities, if any, as to which registration has been demanded pursuant to written contractual arrangements with Persons other than the holders of Registrable Securities hereunder, the Registrable Securities as to which registration has been
requested under this Section 2.2, and the shares of Common Stock or other securities, if any, as to which registration has been requested pursuant to the written contractual piggy-back registration rights of other stockholders of the Company,
exceeds the Maximum Number of Securities, then the Company shall include in any such registration: 
  

 5 








 (a) If the registration is undertaken for the Company’s account: (i) first, the shares of
Common Stock or other securities that the Company desires to sell that can be sold without exceeding the Maximum Number of Securities; (ii) second, to the extent that the Maximum Number of Securities has not been reached under the foregoing
clause (i), the shares of Common Stock or other securities, if any, comprised of Registrable Securities as to which registration has been requested pursuant to the applicable written contractual piggy-back registration rights of such security
holders, Pro Rata, that can be sold without exceeding the Maximum Number of Securities; and (iii) third, to the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (i) and (ii), the shares of
Common Stock or other securities for the account of other Persons that the Company is obligated to register pursuant to written contractual piggy-back registration rights with such Persons and that can be sold without exceeding the Maximum Number of
Securities; and 
 (b) If the registration is a “demand” registration undertaken at the demand of Persons other than the holders
of Registrable Securities, (i) first, the shares of Common Stock or other securities for the account of the demanding Persons that can be sold without exceeding the Maximum Number of Securities; (ii) second, to the extent that the Maximum
Number of Securities has not been reached under the foregoing clause (i), the shares of Common Stock or other securities that the Company desires to sell that can be sold without exceeding the Maximum Number of Securities; (iii) third, to the

(iii), the shares of Common Stock or other securities for the account of other Persons that the Company is obligated to register pursuant to written contractual arrangements with such Persons, that can be sold without exceeding the Maximum Number of
Securities. 
 2.2.3 Withdrawal. Any holder of Registrable Securities may elect to withdraw such holder’s request for inclusion
of Registrable Securities in any Piggy-Back Registration by giving written notice to the Company of such request to withdraw prior to the effectiveness of the Registration Statement. The Company (whether on its own determination or as the result of
a withdrawal by Persons making a demand pursuant to written contractual obligations) may withdraw (or postpone the filing of) a registration statement at any time prior to the effectiveness of the Registration Statement. Notwithstanding any such
withdrawal, the Company shall pay all expenses incurred by the holders of Registrable Securities in connection with such Piggy-Back Registration as provided in Section 3.3. 
 2.3 Registrations on Form S-3. The holders of Registrable Securities may at any time and from time to time, request in writing that the Company
register the resale of any or all of such Registrable Securities on Form S-3 or any similar short-form registration which may be available at such time (“Form S-3”); provided, however, that the Company shall not be obligated to effect such
request through an underwritten offering. Upon receipt of such written request, the Company will give written notice of the proposed registration to all other holders of Registrable Securities, and, as soon as practicable thereafter, effect the
registration of all or such portion of such holder’s or holders’ Registrable Securities as are specified in such request, together with all or such portion of the Registrable Securities or other securities of the Company, if any, of any

expenses, losses, judgments, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or allegedly untrue statement of a material fact contained in any Registration Statement under which the
sale of such Registrable Securities was registered under the Securities Act, any preliminary prospectus, final prospectus or summary prospectus contained in the Registration Statement, or any amendment or supplement to the Registration Statement, or
arise out of or are based upon any omission or the alleged omission to state a material fact required to be stated therein or necessary to make the statement therein not misleading, if the statement or omission was made in reliance upon and in
conformity with information furnished in writing to the Company by such selling holder expressly for use therein, and each selling holder of Registrable Securities shall reimburse the Company, its directors, officers and each Underwriter (if any),
and each other selling holder or controlling Person for any legal or other expenses reasonably incurred by any of them in connection with investigating or defending any such loss, judgment, claim, damage, liability or action. Each selling
holder’s indemnification obligations hereunder shall be several and not joint and shall be limited to the amount of any net proceeds actually received by such selling holder. 
 4.3 Conduct of Indemnification Proceedings. Promptly after receipt by any Person of any notice of any expense, loss, judgment, claim, damage or
liability or any action in respect of which indemnity may be sought pursuant to Section 4.1 or 4.2, such Person (the “Indemnified Party”) shall, if a claim in respect thereof is to be made against any other Person for indemnification
hereunder, notify such other Person (the “Indemnifying Party”) in writing of the expense, loss, judgment, claim, damage, liability or action; provided, however, that the failure by the Indemnified Party to notify the Indemnifying Party
shall not relieve the Indemnifying Party from any liability which the Indemnifying Party may have to such Indemnified Party hereunder, except and solely to the extent the Indemnifying Party is actually prejudiced by such failure. If the Indemnified
Party is seeking indemnification with respect to any claim or action brought against the Indemnified Party, then the Indemnifying Party shall be entitled to participate in such claim or action, and, to the extent that it wishes, jointly with all
other Indemnifying Parties, to assume control of the defense thereof with counsel reasonably satisfactory to the Indemnified Party. After notice from the Indemnifying Party to the Indemnified Party of its election to assume control of the defense of
such claim or action, the Indemnifying Party shall not be liable to the Indemnified Party for any legal or other expenses subsequently incurred by the Indemnified Party in connection with the defense thereof other than reasonable costs of
investigation; provided, however, that in any action in which both the Indemnified Party and the Indemnifying Party are named as defendants, the Indemnified Party shall have the right to employ separate counsel (but no more than one such separate
counsel) to represent the Indemnified Party and its controlling Persons who may be subject to liability arising out of any claim in respect of which indemnity may be sought by the Indemnified Party against the Indemnifying Party, with the reasonable
fees and reasonable expenses of such counsel to be paid by such Indemnifying Party if, based upon the written opinion of counsel of such Indemnified Party, representation of both parties by the same counsel would be inappropriate due to actual or
potential differing interests between them. No Indemnifying Party shall, without the prior written consent of the Indemnified Party, consent to entry of judgment or effect any settlement of any claim or pending or threatened proceeding in respect of
which the Indemnified Party is or could have been a party and indemnity could have been sought hereunder by such Indemnified Party, unless such judgment or settlement includes an unconditional release of such Indemnified Party from all liability
arising out of such claim or proceeding. 
 4.4 Contribution. 
 4.4.1 If the indemnification provided for in the foregoing Sections 4.1 and 4.2 is unavailable to any Indemnified Party in respect of any expense, loss,
judgment, claim, damage, liability 

  

 11 








 
or action referred to herein, then each such Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall contribute to the amount paid or
payable by such Indemnified Party as a result of such expense, loss, judgment, claim, damage, liability or action in such proportion as is appropriate to reflect the relative fault of the Indemnified Parties and the Indemnifying Parties in
connection with the actions or omissions which resulted in such expense, loss, judgment, claim, damage, liability or action, as well as any other relevant equitable considerations. The relative fault of any Indemnified Party and any Indemnifying
Party shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by such Indemnified Party
or such Indemnifying Party and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. 
 4.4.2 The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 4.4 were determined by pro rata allocation or by any other method of allocation which does not take
account of the equitable considerations referred to in the immediately preceding Section 4.4.1. 
 4.4.3 The amount paid or payable by
an Indemnified Party as a result of any expense, loss, judgment, claim, damage, liability or action referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, any legal or other
expenses incurred by such Indemnified Party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 4.4, no holder of Registrable Securities shall be required to contribute any
amount in excess of the dollar amount of the net proceeds (after payment of any underwriting fees, discounts, commissions or taxes) actually received by such holder from the sale of Registrable Securities which gave rise to such contribution
obligation. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. 
 5. Underwriting and Distribution. 
 5.1 Rule 144. The Company covenants that it shall file any reports required to be filed by it under the Securities Act and the Exchange Act and shall take such further action as the holders of Registrable Securities may reasonably
request, all to the extent required from time to time to enable such holders to sell Registrable Securities without registration under the Securities Act within the limitation of the exemptions provided by Rule 144 under the Securities Act, as such
Rule may be amended from time to time, or any similar Rule or regulation hereafter adopted by the Commission. 
 6. Miscellaneous.

 6.1 Other Registration Rights. The Company represents and warrants that no Person, other than a holder of the Registrable
Securities, has any right to require the Company to register any shares of the Company’s capital stock for sale or to include shares of the Company’s capital stock in any registration filed by the Company for the sale of shares of capital
stock for its own account or for the account of any other Person. 
 6.2 Assignment; No Third Party Beneficiaries. This Agreement and
the rights, duties and obligations of the Company hereunder may not be assigned or delegated by the Company in whole or in part. This Agreement and the rights, duties and obligations of the holders of Registrable Securities hereunder may be freely
assigned or delegated by such holder of Registrable Securities in conjunction with and to the extent of any transfer of at least twenty percent (20%) of the Registrable Securities held by any such holder. This Agreement and the provisions
hereof shall be binding upon and 

  

 12 








 
shall inure to the benefit of each of the parties hereto and the permitted assigns of the Investor or holder of Registrable Securities or of any assignee of
the Investor or holder of Registrable Securities. This Agreement is not intended to confer any rights or benefits on any Persons that are not party hereto other than as expressly set forth in Article 4 and this Section 6.2. 
 6.3 Notices. All notices, demands, requests, consents, approvals or other communications (collectively, “Notices”) required or permitted
to be given hereunder or which are given with respect to this Agreement shall be in writing and shall be personally served, delivered by reputable overnight courier service with charges prepaid, or transmitted by hand delivery or facsimile,
addressed as set forth below, or to such other address as such party shall have specified most recently by written notice. Notice shall be deemed given on the date of service or transmission if personally served or transmitted by facsimile;
provided, that if such service or transmission is not on a business day or is after normal business hours, then such notice shall be deemed given on the next business day. Notice otherwise sent as provided herein shall be deemed given on the next
business day following timely delivery of such notice to a reputable overnight courier service with an order for next-day delivery.

 6.7 Modifications and Amendments. The Company may from time to time supplement or amend this
Agreement without the approval of any of the Investors in order to cure any ambiguity, to correct or supplement any provision contained herein that may be defective or inconsistent with any other provisions herein, or to make any other provisions in
regard to matters or questions arising hereunder that the Company may deem necessary or desirable and that the Company, in the exercise of reasonable judgment, determines will not materially adversely affect the interest of the Investors. All other

 6.8
Titles and Headings. Titles and headings of sections of this Agreement are for convenience only and shall not affect the construction of any provision of this Agreement. 
 6.9 Waivers and Extensions. Any party to this Agreement may waive any right, breach or default which such party has the right to waive, provided
that such waiver will not be effective against the waiving party unless it is in writing, is signed by such party, and specifically refers to this Agreement. Waivers may be made in advance or after the right waived has arisen or the breach or
default waived has occurred. Any waiver may be conditional. No waiver of any breach of any agreement or provision herein contained shall be deemed a waiver of any preceding or succeeding breach thereof nor of any other agreement or provision herein
contained. No waiver or extension of time for performance of any obligations or acts shall be deemed a waiver or extension of the time for performance of any other obligations or acts. 
 6.10 Remedies Cumulative. In the event that the Company fails to observe or perform any covenant or agreement to be observed or performed under
this Agreement, the Investor or any other holder of Registrable Securities may proceed to protect and enforce its rights by suit in equity or action at law, whether for specific performance of any term contained in this Agreement or for an
injunction against the breach of any such term or in aid of the exercise of any power granted in this Agreement or to enforce any other legal or equitable right, or to take any one or more of such actions, without being required to post a bond. None
of the rights, powers or remedies conferred under this Agreement shall be mutually exclusive, and each such right, power or remedy shall be cumulative and in addition to any other right, power or remedy, whether conferred by this Agreement or now or
hereafter available at law, in equity, by statute or otherwise. 
 6.11 Governing Law. This Agreement shall be governed by, and
construed in accordance with, the laws of the State of New York applicable to contracts executed in and to be performed in that State, including, without limitation, Sections 5-1401 and 5-1402 of the New York General Obligations Law and the New York
Civil Practice Laws and Rules 327(b). The parties hereto agree that any action, proceeding or claim against it arising out of or relating in any way to this Agreement shall be brought and enforced in the courts of the State of New York or the United
States District Court for the Southern District of New York, and the parties hereto irrevocably submit to such jurisdiction, which jurisdiction shall be exclusive. The parties hereto hereby waive any objection to such exclusive jurisdiction and that
such courts represent an inconvenient forum. 
 6.12 Waiver of Trial by Jury. Each party hereto hereby irrevocably and unconditionally
waives the right to a trial by jury in any action, suit, counterclaim or other proceeding (whether based on contract, tort or otherwise) arising out of, connected with or relating to this Agreement, the transactions contemplated hereby, or the
actions of the Investor in the negotiation, administration, performance or enforcement hereof.
