 2. REGISTRATION RIGHTS. 

2.1 Demand Registration.

Combination with respect to the Founders’ Warrants (or underlying shares of Common Stock) and Working Capital Warrants (or underlying shares of Common Stock) or (ii) three months prior to the Release Date with respect to all other Registrable
Securities, the holders of a majority-in-interest of such Founders’ Warrants (or underlying shares of Common Stock), Working Capital Warrants (or underlying shares of Common Stock) or other Registrable Securities, as the case may be, held by
the Investors, officers or directors of the Company or their affiliates, or the transferees of the Investors, may make a written demand for registration under the Securities Act of all or part of their Founders’ Warrants (or underlying shares
of Common Stock), Working Capital Warrants (or underlying shares of Common Stock) or other Registrable Securities, as the case may be (a “Demand Registration”). Any demand for a Demand Registration shall specify the number of
shares of Registrable Securities proposed to be sold and the intended method(s) of distribution thereof. The Company will within 10 days of the Company’s receipt of the Demand Registration 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 shares of Registrable Securities in such registration, a
“Demanding Holder”) shall so notify the Company within ten (10) days after the 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 Section 2.1.4 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 all 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 

  
 3 








 
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, (i) such stop order or injunction is removed, rescinded or otherwise terminated, and (ii) a majority-in-interest of the Demanding Holders thereafter affirmatively elect to continue the offering and notify the Company in
writing, but in no event later than five (5) days of such election; 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 of the Demanding Holders so elect 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 of the holders initiating the Demand Registration. 
 2.1.4. Reduction of Offering. If the managing Underwriter
or Underwriters for a Demand Registration that is to be an underwritten offering, in good faith, advises the Company and the Demanding Holders in writing that the dollar amount or number of shares 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, 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 shares 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 shares, as applicable, the “Maximum Number of Shares”), then the Company shall include in such
registration: (i) 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 Demanding Holder has requested be included in such
registration, regardless of the number of shares held by each such Demanding Holder (such proportion is referred to herein as “Pro Rata”)) that can be sold without exceeding the Maximum Number of Shares; (ii) to the extent
that the Maximum Number of Shares has not been reached under the foregoing clause (i), the Registrable Securities of holders exercising their rights to register their Registrable Securities pursuant to Section 2.2; (iii) to the extent that the
Maximum Number of Shares has not been reached under the foregoing clauses (i) and (ii), the shares of Common Stock or other securities that the Company desires to sell that can be sold without exceeding the Maximum Number of Shares; and (iv) to the
extent that the Maximum Number of Shares have not been reached under the foregoing clauses (i), (ii) and (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 and that can be sold without exceeding the Maximum Number of Shares. 
 2.1.5.
Withdrawal. If a majority-in-interest of the Demanding Holders disapprove 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. If the majority-in-interest of the Demanding Holders withdraws from a proposed offering relating to a Demand Registration, then such registration shall not count as a Demand Registration provided for in this Section 2.1. 

  
 4 








 2.2 Piggy-Back Registration. 

2.2.1. Piggy-Back Rights. If at any time on or after the date the Company consummates a Business Combination 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
or for stockholders of the Company for their account (or by the Company and by stockholders of the Company including, without limitation, pursuant to Section 2.1), other than a Registration Statement (i) filed in connection with any employee stock
option or other benefit plan, (ii) for an exchange offer or offering of securities solely to the Company’s existing stockholders, (iii) for an offering of debt that is convertible into equity securities of the Company or (iv) for a dividend
reinvestment plan, then the Company shall (x) give written notice of such proposed filing to the holders of Registrable Securities as soon as practicable but in no event less than ten (10) days before the anticipated filing date, 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 shares 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, in good faith, cause such Registrable Securities to be included in such registration and shall use its best 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 which the Company desires to sell, taken together with shares of Common Stock, if any, as to which registration has been demanded pursuant to separate written 

  
 5 








 
contractual arrangements with persons or entities 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, 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 Shares, then the
Company shall include in any such registration: 
 a) If the registration is undertaken for the Company’s account: (A)
the shares of Common Stock or other securities that the Company desires to sell that can be sold without exceeding the Maximum Number of Shares; (B) to the extent that the Maximum Number of Shares has not been reached under the foregoing clause (A),
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 Shares; and (C) to the extent that the Maximum Number of Shares has not been reached under the foregoing clauses (A) and (B), 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 Shares; and 

b) If the registration is a “demand” registration undertaken at the demand of persons or entities other than the holders of
Registrable Securities, (A) 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 Shares; (B) to the extent that the Maximum Number of Shares has not been
reached under the foregoing clause (A), collectively the shares of Common Stock or other securities comprised of Registrable Securities, Pro Rata, as to which registration has been requested pursuant to the terms hereof, as applicable, that can be
sold without exceeding the Maximum Number of Shares; (C) to the extent that the Maximum Number of Shares has not been reached under the foregoing clauses (A) and (B), the shares of Common Stock or other securities that the Company desires to sell
that can be sold without exceeding the Maximum Number of Shares; and (D) to the extent that the Maximum Number of Shares has not been reached under the foregoing clauses (A), (B) and (C), 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 Shares. 

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


  
 6 








 
withdrawal by persons making a demand pursuant to written contractual obligations) may withdraw 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. 

2.2.4. Unlimited Piggy-Back Registration Rights. For purposes of clarity, any registration effected pursuant to Section 2.2
hereof shall not be counted as a registration pursuant to a Demand Registration effected under Section 2.1 hereof. 
 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
promptly give written notice of the proposed registration to all other holders of Registrable Securities, and each holder of Registrable Securities who thereafter wishes to include all or a portion of such holder’s Registrable Securities in
such registration shall so notify the Company, in writing, within ten (10) days after the receipt by the holder of the notice from the Company, and, as soon as practicable thereafter but not more than twelve (12) days after the Company’s
initial receipt of such written request for a registration, 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 other holder or holders joining in such request; provided, however, that the Company shall not be obligated to effect any such registration pursuant to this Section 2.3 if:
(i) Form S-3 is not available for such offering; or (ii) the holders of the Registrable Securities, 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) at any aggregate price to the public of less than $500,000. Registrations effected pursuant to this Section 2.3 shall not be counted as Demand Registrations effected pursuant to Section 2.1. 

3. REGISTRATION PROCEDURES. 

3.1 Filings; Information. Whenever the Company is required to effect the registration of any Registrable Securities pursuant to Section
2, the Company shall use its best efforts to effect the registration and sale of such Registrable Securities in accordance with the intended method(s) of distribution thereof as expeditiously as practicable, and in connection with any such request:

 3.1.1. Filing Registration Statement. The Company shall, as expeditiously as possible and in any event within sixty (60) days
after receipt of a request for a Demand Registration pursuant to Section 2.1, prepare and file with the Commission a Registration Statement on any form for which the Company then qualifies or which counsel for the Company shall deem appropriate and
which form shall be available for the sale of all Registrable Securities to be registered thereunder in accordance with the intended method(s) of distribution thereof, and shall use its best efforts to cause such Registration Statement to become and
remain effective for the period required by Section 3.1.3; provided, however, that the Company shall have the right to 

  
 7 








 
defer any Demand Registration for up to thirty (30) days, and any Piggy-Back Registration for such period as may be applicable to deferment of any demand registration to which such Piggy-Back
Registration relates, in each case if the Company shall furnish to the holders a certificate signed by the Chairman of the Board of Directors or President 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 effected at such time; provided further, however, that the Company shall not have the right to exercise the right set forth in the
immediately preceding proviso more than once in any 365-day period in respect of a Demand Registration hereunder. 
 3.1.2. Copies.
The Company shall, prior to filing a Registration Statement or prospectus, or any amendment or supplement thereto, furnish without charge to the holders of Registrable Securities included in such registration, and such holders’ legal counsel,

file with the Commission such amendments, including post-effective amendments, and supplements to such Registration Statement and the prospectus used in connection therewith as may be necessary to keep such Registration Statement effective and in

Registration Statement (which period shall not exceed the sum of one hundred eighty (180) days plus any period during which any such disposition is interfered with by any stop order or injunction of the Commission or any governmental agency or
court) or such securities have been withdrawn.

(iii) the issuance or threatened issuance by the Commission of any stop order (and the Company shall take all actions required to prevent the entry of such stop order or to remove it if entered); and (iv) any request by the Commission for any
amendment or supplement to such Registration Statement or any prospectus relating thereto or for additional information or of the occurrence of an event requiring the preparation of a supplement or amendment to such prospectus so that, as thereafter
delivered to the purchasers of the securities covered by such Registration Statement, such prospectus will not contain an untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the
statements therein not misleading, and promptly make available to the holders of Registrable Securities included in such Registration Statement any such supplement or amendment; except that before 

  
 8 








 
filing with the Commission a Registration Statement or prospectus or any amendment or supplement thereto, including documents incorporated by reference, the Company shall furnish to the holders
of Registrable Securities included in such Registration Statement and to the legal counsel for any such holders, copies of all such documents proposed to be filed sufficiently in advance of filing to provide such holders and legal counsel with a
reasonable opportunity to review such documents and comment thereon, and the Company shall not file any Registration Statement or prospectus or amendment or supplement thereto, including documents incorporated by reference, to which such holders or
their legal counsel shall reasonably object. 
 3.1.5. Securities Laws Compliance. The Company shall use its best efforts to (i)
register or qualify the Registrable Securities covered by the Registration Statement under such securities or “blue sky” laws of such jurisdictions in the United States as the holders of Registrable Securities included in such Registration
Statement (in light of their intended plan of distribution) may request and (ii) take such action necessary to cause such Registrable Securities covered by the Registration Statement to be registered with or approved by such other governmental
authorities or securities exchanges, including the Nasdaq Capital Market, as may be necessary by virtue of the business and operations of the Company and do any and all other acts and things that may be necessary or advisable to enable the holders
of Registrable Securities included in such Registration Statement to consummate the disposition of such Registrable Securities in such jurisdictions; provided, however, that the Company shall not be required to qualify generally to do business in
any jurisdiction where it would not otherwise be required to qualify but for this paragraph or subject itself to taxation in any such jurisdiction.

agreement which are made to or for the benefit of any Underwriters, to the extent applicable, shall also be made to and for the benefit of the holders of Registrable Securities included in such registration statement. No holder of Registrable
Securities included in such registration statement shall be required to make any representations or warranties in the underwriting agreement except as reasonably requested by the Underwriters and, if applicable, with respect to such holder’s
organization, good standing, authority, title to Registrable Securities, lack of conflict of such sale with such holder’s material agreements and organizational documents, and with respect to written information relating to such holder that
such holder has furnished in writing expressly for inclusion in such Registration Statement. 
 3.1.7. Cooperation. The principal
executive officer of the Company, the principal financial officer of the Company, the principal accounting officer of the Company and all other officers and members of the management of the Company shall cooperate fully in any offering of

with Underwriters, attorneys, accountants and potential investors. 
 3.1.8. Records. The Company shall make available for inspection
by the holders of Registrable Securities included in such Registration Statement, any Underwriter participating

Statement or any Underwriter, all financial and other records, pertinent corporate documents and properties of the Company, as shall be necessary to enable them to exercise their due diligence responsibility, and cause the Company’s officers,
directors and employees to supply all information requested by any of them in connection with such Registration Statement.

and that no stop order is in effect.

3.1.11. Listing. The Company shall use its best efforts to cause all Registrable Securities included in any registration to be listed

holders of a majority of the Registrable Securities included in such registration. 
 3.1.12. Transfer Agent. The Company shall
provide a transfer agent or warrant agent, as applicable, and registrar for all such Registrable Securities no later than the effective date of the registration statement. 

3.1.13. Misstatements. The Company shall notify the holders at any time when a prospectus relating to such registration statement 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 an omission to state
a material fact required to be stated in a registration statement or prospectus, or necessary to make the statements therein in the light of the circumstances under which they were made not misleading (a “Misstatement”), and then to
correct such Misstatement. 
 3.2 Obligation to Suspend Distribution. Upon receipt of any notice from the Company of the happening of
any event of the kind described in Section 3.1.4(iv), or, in the case of a resale registration on Form S-3 pursuant to Section 2.3 hereof, upon any suspension by the Company, pursuant to a written insider trading compliance program adopted by the
Company’s Board of Directors, of the ability of all “insiders” covered by such program to transact in the Company’s 

  
 10 








 
securities because of the existence of material non-public information, each holder of Registrable Securities included in any registration shall immediately discontinue disposition of such
Registrable Securities pursuant to the Registration Statement covering such Registrable Securities until such holder receives the supplemented or amended prospectus contemplated by Section 3.1.4(iv) or the restriction on the ability of
“insiders” to transact in the Company’s securities is removed, as applicable, and, if so directed by the Company, each such holder will deliver to the Company all copies, other than permanent file copies then in such holder’s
possession, of the most recent prospectus covering such Registrable Securities at the time of receipt of such notice.

Additionally, in an underwritten offering, all selling stockholders and the Company shall bear the expenses of the underwriter pro rata in proportion to the respective amount of shares each is selling in such offering. 

3.4 Information. The holders of Registrable Securities shall provide such information as may reasonably be requested by the Company, or
the managing Underwriter, if any, in connection with the preparation of any Registration Statement, including amendments and supplements thereto, in order to effect the registration of any Registrable Securities under the Securities Act pursuant to

 3.5
Requirements for Participation in Underwritten Offerings. No person may participate in any underwritten offering for equity securities of the Company pursuant to a registration initiated by the Company hereunder unless such person (i) agrees

agreements and other customary documents as may be reasonably required under the terms of such underwriting arrangements. 

  
 11 








 3.6 Suspension of Sales; Adverse Disclosure. Upon receipt of written notice from the
Company that a registration statement or prospectus contains a Misstatement, each of the Holders shall forthwith discontinue disposition of Registrable Securities until it has received copies of a supplemented or amended prospectus correcting the
Misstatement (it being understood that the Company hereby covenants to prepare and file such supplement or amendment as soon as practicable after the time of such notice), or until it is advised in writing by the Company that the use of the
prospectus may be resumed. If the filing, initial effectiveness or continued use of a registration statement in respect of any registration at any time would require the Company to make an Adverse Disclosure (as defined below) or would require the
inclusion in such registration statement of financial statements that are unavailable to the Company for reasons beyond the Company’s control, the Company may, upon giving prompt written notice of such action to the holders, delay the filing or
initial effectiveness of, or suspend use of, such registration statement for the shortest period of time, but in no event more than thirty (30) days, determined in good faith by the Company to be necessary for such purpose. In the event the Company
exercises its rights under the preceding sentence, the holders agree to suspend, immediately upon their receipt of the notice referred to above, their use of the prospectus relating to any registration in connection with any sale or offer to sell
Registrable Securities. The Company shall immediately notify the Holders of the expiration of any period during which it exercised its rights under this Section 3.6. “Adverse Disclosure” shall mean any public disclosure of material
non-public information, which disclosure, in the good faith judgment of the principal executive officer or principal financial officer of the Company, after consultation with counsel to the Company, (i) would be required to be made in any
registration statement or prospectus in order for the applicable registration statement or prospectus not to contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements contained therein (in the
case of any prospectus and any preliminary prospectus, in the light of the circumstances under which they were made) not misleading, (ii) would not be required to be made at such time if the registration statement were not being filed, and (iii) the
Company has a bona fide business purpose for not making such information public. 
 3.7 Reporting Obligations. As long as any holder
shall own Registrable Securities, the Company, at all times while it shall be reporting under the Exchange Act, covenants to file timely (or obtain extensions in respect thereof and file within the applicable grace period) all reports required to be
filed by the Company after the date hereof pursuant to Sections 13(a) or 15(d) of the Exchange Act and to promptly furnish the holders with true and complete copies of all such filings. The Company further covenants that it shall take such further
action as any holder may reasonably request, all to the extent required from time to time to enable such holder to sell shares of the Common Stock held by such holder without registration under the Securities Act within the limitation of the
exemptions provided by Rule 144 promulgated under the Securities Act, including providing any legal opinions. Upon the request of any holder, the Company shall deliver to such holder a written certification of a duly authorized officer as to whether
it has complied with such requirements.

 4. INDEMNIFICATION AND CONTRIBUTION. 

4.1 Indemnification by the Company. The Company agrees to indemnify and hold harmless each Investor and each other holder of
Registrable Securities, and each of their respective officers, employees, affiliates, directors, partners, members, attorneys and agents, and each person, if any, who controls an Investor and each other holder of Registrable Securities (within the
meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) (each, an “Investor Indemnified Party”), from and against any expenses, losses, judgments, claims, damages or liabilities, whether joint or
several, arising out of or 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 such Registration Statement, or arising out of or based upon any omission (or alleged omission) to state a
material fact required to be stated therein or necessary to make the statements therein not misleading, or any violation by the Company of the Securities Act or any rule or regulation promulgated thereunder applicable to the Company and relating to
action or inaction required of the Company in connection with any such registration; and the Company shall promptly reimburse the Investor Indemnified Party for any legal and any other expenses reasonably incurred by such Investor Indemnified Party
in connection with investigating and defending any such expense, loss, judgment, claim, damage, liability or action; provided, however, that the Company will not be liable in any such case to the extent that any such expense, loss, claim, damage or
liability arises out of or is based upon any untrue statement or allegedly untrue statement or omission or alleged omission made in such Registration Statement, preliminary prospectus, final prospectus, or summary prospectus, or any such amendment
or supplement, in reliance upon and in conformity with information furnished to the Company, in writing, by such selling holder expressly for use therein. The Company also shall indemnify any Underwriter of the Registrable Securities, their
officers, affiliates, directors, partners, members and agents and each person who controls such Underwriter on substantially the same basis as that of the indemnification provided above in this Section 4.1. 

4.2 Indemnification by Holders of Registrable Securities. Each selling holder of Registrable Securities will, in the event that any
registration is being effected under the Securities Act pursuant to this Agreement of any Registrable Securities held by such selling holder, indemnify and hold harmless the Company, each of its directors and officers and each underwriter (if any),
and each other selling holder and each other person, if any, who controls another selling holder or such underwriter within the meaning of the Securities Act, against any losses, claims, judgments, damages or liabilities, whether joint or several,
insofar as such losses, claims, judgments, 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 shall reimburse the Company, its directors and officers, and each other selling holder or controlling person for any
legal or other expenses reasonably incurred by any of them in 

  
 13 








 
connection with investigation or defending any such loss, 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. Each selling holder of Registrable Securities shall indemnify any Underwriter of the Registrable Securities, their officers, affiliates, directors,
partners, members and agents and each person who controls such Underwriter to the same extent as provided in the foregoing with respect to indemnification of the Company. 

4.3 Conduct of Indemnification Proceedings. Promptly after receipt by any person of any notice of any loss, 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 loss, claim, judgment, 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 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 fees and
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, 4.2 and 4.3 is unavailable to any Indemnified Party in respect of
any loss, claim, damage, liability 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 loss,
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 

  
 14 








 
with the actions or omissions which resulted in such loss, 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. The amount paid or payable by an Indemnified Party as a result of any loss,
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. 

4.5 Survival. The indemnification provided for under this Agreement shall remain in full force and effect regardless of any
investigation made by or on behalf of the Indemnified Party or any officer, director or controlling person of such Indemnified Party and shall survive the transfer of securities. 

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 rules 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. Further, the Company represents and warrants that this
Agreement supersedes any other registration rights agreement or agreement with similar terms and conditions and in the event of a conflict between any such agreement or agreements and this Agreement, the terms of this Agreement shall prevail. 

  
 15 








 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 Registrable Securities by any such holder. This Agreement and the provisions hereof shall be binding upon and shall inure to the benefit of each of the
parties 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. No assignment by any party hereto of such party’s rights, duties and obligations hereunder shall be binding upon or obligate the Company unless and until the
Company shall have received (i) written notice of such assignment and (ii) the written agreement of the assignee, in a form reasonably satisfactory to the Company, to be bound by the terms and provisions of this Agreement (which may be accomplished
by an addendum or certificate of joinder to this Agreement). 
 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 air
courier service with charges prepaid, or transmitted by hand delivery, telegram, telex 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 telegram, telex or 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 air courier service with an order for next-day delivery.

 6.4 Severability. This Agreement shall be deemed severable, and the invalidity or unenforceability of any term or
provision hereof shall not affect the validity or enforceability of this Agreement or of any other term or provision hereof. Furthermore, in lieu of any such invalid or unenforceable term or provision, the parties hereto intend that there shall be
added as a part of this Agreement a provision as similar in terms to such invalid or unenforceable provision as may be possible that is valid and enforceable. 

6.5 Counterparts. This Agreement may be executed in multiple counterparts, each of which shall be deemed an original, and all of which
taken together shall constitute one and the same instrument. 
 6.6 Entire Agreement. This Agreement (including all agreements
entered into pursuant hereto and all certificates and instruments delivered pursuant hereto and thereto) constitute the entire agreement of the parties with respect to the subject matter hereof and supersede all prior and contemporaneous agreements,
representations, understandings, negotiations and discussions between the parties, whether oral or written. 
 6.7 Modifications and
Amendments. Upon the written consent of the Company and the holders of at least sixty-six and two-thirds percent (66-2/3%) of the Registrable Securities at the time in question, compliance with any of the provisions, covenants and conditions set
forth in this Agreement may be waived, or any of such provisions, covenants or conditions may be amended or modified; provided, however, that notwithstanding the foregoing, any amendment hereto or waiver hereof that adversely affects one holder of
Registrable Securities, solely in its capacity as a holder of the shares of Common Stock of the Company, in a manner that is materially different from the other holders of Registrable Securities (in such capacity) shall require the consent of the
holder so affected. No course of dealing between any holders of Registrable Securities or the Company and any other party hereto or any failure or delay on the part of a holder of Registrable Securities or the Company in exercising any rights or
remedies under this Agreement shall operate as a waiver of any rights or remedies of any holder of Registrable Securities or the Company. No single or partial exercise of any rights or remedies under this Agreement by a party shall operate as a
waiver or preclude the exercise of any other rights or remedies hereunder or thereunder by such party. 
 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 

  
 17 








 
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, interpreted under, and construed in accordance with the internal laws of the State of New York applicable to agreements made and to be performed within the State of New York, without giving effect to any choice-of-law provisions thereof
that would compel the application of the substantive laws of any other jurisdiction. 
 6.12 Waiver of Trial by Jury. Each party
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.
