Securities who thereafter wishes to include all or a portion of such Holder’s Registrable Securities in the Demand Registration (each such Holder that includes all or a portion of such
Holder’s Registrable Securities in such Registration, a “Requesting Holder”) shall so notify the Company, in writing, within five (5) days after the receipt by the Holder of the notice from the Company. Upon receipt
by the Company of any such written notification from a Requesting Holder, such Requesting Holder shall be entitled to have its Registrable Securities included in a Registration pursuant to a Demand Registration, and the Company shall effect, as soon
thereafter as practicable, but not more than forty-five (45) days immediately after the Company’s receipt of the Demand Registration, the Registration of all Registrable Securities requested by the Demanding Holders and the Requesting
Holders pursuant to such Demand Registration. Under no circumstances shall the Company be obligated to effect more than an aggregate of two (2) Registrations pursuant to a Demand Registration under this Section 2.1.1 (not
counting any Demand Registration initiated solely by Cowen Investments), subject to the limitations set forth in Section 3.6 of this Agreement; provided, that a Registration shall not be counted for such purposes unless a Form S-1 or any similar long-form registration statement that may be available at such time (“Form S-1”) has
become effective and all of the Registrable Securities requested by the Requesting Holders to be registered on behalf of the Requesting Holders in such Form S-1 Registration have been sold, in
accordance with Section 3.1 of this Agreement. 
 2.1.2. Effective Registration. Notwithstanding the provisions of
Section 2.1.1 above or any other part of this Agreement, a Registration pursuant to a Demand Registration will not count as a Registration unless and until (i) a Form S-1 filed
with the Commission in connection with the Registration has been declared effective by the Commission, and (ii) the Company has complied with all of its obligations under this Agreement with respect thereto; provided, 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 initiating such Demand Registration thereafter affirmatively elect to continue with such Registration and
accordingly notify the Company in writing of such election, which notice shall be received by the Company not later than five (5) days after the removal of any such stop order or injunction; provided, further, that the
Company shall not be obligated to file a second Registration Statement until a Registration Statement that has been previously filed pursuant to a Demand Registration becomes effective or is terminated.

such Underwritten Offering and the inclusion of such Holder’s Registrable Securities in such Underwritten Offering to the extent provided herein. All such Holders proposing to distribute their Registrable Securities through an Underwritten
Offering under this Section 2.1.3 shall enter into an underwriting agreement in customary form with the Underwriter(s) selected for such Underwritten Offering by a majority-in-interest of the Demanding Holders initiating the Demand Registration. 

2.1.4. Reduction of Underwritten Offering. If the managing Underwriter(s) for a Demand Registration that is to be an Underwritten
Offering, in good faith, advises the Company, the Demanding Holders and the Requesting Holders in writing that the dollar amount or number of Registrable Securities which the Demanding Holders and Requesting Holders desire to sell, taken together
with all other shares of Common Stock or other equity securities which the Company desires to sell and the shares of Common Stock, if any, as to which a Registration has been requested pursuant to separate 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 equity securities that can be sold in such Underwritten Offering without adversely affecting the proposed offering price, the
timing, the distribution method, or the probability of success of such Underwritten Offering (such maximum dollar amount or maximum number of securities, as applicable, the “Maximum Number of Securities”), then the Company
shall include in such Underwritten Offering, as follows: (i) first, the Registrable Securities of the Demanding Holders and the Requesting Holders (if any) (pro rata based on the respective number of Registrable Securities that each

the Registration Expenses incurred in connection with a Registration pursuant to a Demand Registration prior to its withdrawal under this Section 2.1.5; provided that if the Company pays such expenses related to a Demand Registration
initiated by Cowen Investments, such registration shall count as a Demand Registration for purposes of Section 3.6. 

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

the managing Underwriter(s) of a proposed Underwritten Offering to permit the Registrable Securities requested to be included in a Piggyback 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

register all or such portion of such Holder’s Registrable Securities as are specified in such written request, together with all or such portion of Registrable Securities of any other Holder or Holders joining in such request as are specified

 3.1.6 provide a transfer agent or warrant agent, as applicable, and registrar
for all such Registrable Securities no later than the effective date of such Registration Statement; 
 3.1.7 advise each seller of such
Registrable Securities, promptly after it shall receive notice or obtain knowledge thereof, of the issuance of any stop order by the Commission suspending the effectiveness of such Registration Statement or the initiation or threatening of any
proceeding for such purpose and promptly use its reasonable best efforts to prevent the issuance of any stop order or to obtain its withdrawal if such stop order should be issued; 

3.1.8 at least five (5) days prior to the filing of any Registration Statement or Prospectus or any amendment or supplement to such
Registration Statement or Prospectus or any document that is to be incorporated by reference into such Registration Statement or Prospectus, furnish a copy thereof to each seller of such Registrable Securities or its counsel; 

3.1.9 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 a Misstatement, and then to correct such Misstatement as set forth in Section
3.4 hereof; 
 3.1.10 permit a representative of the Holders (such representative to be selected by a majority of the participating
holders), the Underwriters, if any, and any attorney or accountant retained by such Holders or Underwriter to participate, at each such person’s own expense, in the preparation of the Registration Statement, and cause the Company’s
officers, directors and employees to supply all information reasonably requested by any such representative, Underwriter, attorney or accountant in connection with the Registration; provided, that such representatives or
Underwriters enter into a confidentiality agreement, in form and substance reasonably satisfactory to the Company, prior to the release or disclosure of any such information; 

3.1.11 obtain a “cold comfort” letter from the Company’s independent registered public accountants in the event of an
Underwritten Registration, in customary form and covering such matters of the type customarily covered by “cold comfort” letters as the managing Underwriter may reasonably request, and may be found reasonably satisfactory to a majority-in-interest of the participating Holders; 

3.1.12 on the date the Registrable Securities are delivered for sale pursuant to such Registration, obtain an opinion, dated such date, of
counsel representing the Company for the purposes of such Registration, addressed to the Holders, the placement agent or sales agent, if any, and the Underwriters, if any, covering such legal matters with respect to the Registration in respect of
which such opinion is being given as the Holders, placement agent, sales agent, or Underwriter may reasonably request and as are customarily included in such opinions and negative assurance letters, and may be found reasonably satisfactory to a
majority in interest of the participating Holders; 
 3.1.13 in the event of any Underwritten Offering, enter into and perform its
obligations under an underwriting agreement, in usual and customary form, with the managing Underwriter of such offering; 
 3.1.14 make
available to its security holders, as soon as reasonably practicable, an earnings statement covering the period of at least twelve (12) months beginning with the first day of the Company’s first full calendar quarter after the effective
date of the Registration Statement which satisfies the provisions of Section 11(a) of the Securities Act and Rule 158 thereunder (or any successor rule promulgated thereafter by the Commission); 

3.1.15 if the Registration involves the Registration of Registrable Securities involving gross proceeds in excess of $25,000,000, use its
reasonable efforts to make available senior executives of the Company to participate in customary “road show” presentations that may be reasonably requested by the Underwriter in any Underwritten Offering; and 







 3.1.16 otherwise, in good faith, cooperate reasonably with, and take such customary actions as
may reasonably be requested by the Holders, in connection with such Registration. 
 3.2 Registration Expenses. The Registration
Expenses of all Registrations shall be borne by the Company. It is acknowledged by the Holders that the Holders shall bear all incremental selling expenses relating to the sale of Registrable Securities, such as Underwriters’ commissions and
discounts, brokerage fees, Underwriter marketing costs and, other than as set forth in the definition of “Registration Expenses”, all reasonable fees and expenses of any legal counsel representing the Holders. 

3.3 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 to sell such person’s securities on the basis provided in any underwriting arrangements approved by the Company, and
(ii) completes and executes all customary questionnaires, powers of attorney, indemnities, lock-up agreements, underwriting agreements and other customary documents as may be reasonably required
under the terms of such underwriting arrangements. 
 3.4 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 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 3.4. 

3.5 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 (or any
successor rule promulgated thereafter by the Commission), 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. 
 3.6 Limitations on Registration Rights. Notwithstanding anything herein to the contrary,
each of (i) Cowen Investments, Silverberg and Bernstein may not exercise its or his rights under Sections 2.1 and 2.2 hereunder after five (5) and seven (7) years after the effective date of the
registration statement relating to the Company’s initial public offering, respectively, and (ii) Cowen Investments, Silverberg and Bernstein may not exercise its or his rights under Section 2.1 more than one time. 

4. INDEMNIFICATION AND CONTRIBUTION. 

4.1 Indemnification by the Company. The Company agrees to indemnify, to the extent permitted by law, and hold harmless each Holder
of Registrable Securities, its officers and directors, and each person who controls such Holder (within the meaning of the Securities Act), from and against any expenses, losses, judgments, claims, damages or liabilities (including reasonable
attorney’s fees), whether joint or several, arising out of or based upon any untrue or alleged untrue statement of material fact contained in any Registration Statement, Prospectus or preliminary Prospectus, or any amendment or supplement to
any of them, or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar 







 
as the same are caused by or contained in any information furnished in writing to the Company by the Holder expressly for use therein. The Company also shall indemnify any Underwriter of the
Registrable Securities, their officers and directors, and each person who controls such Underwriter (within the meaning of the Securities Act) 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. In connection with any
Registration Statement in which a Holder of Registrable Securities is participating, such Holder shall furnish to the Company in writing such information and affidavits as the Company reasonably requests for use in connection with any such
Registration Statement or Prospectus and, to the extent permitted by law, shall indemnify the Company, its directors and officers and agents and each person who controls the Company (within the meaning of the Securities Act) against any losses,
claims, damages, liabilities and expenses (including without limitation reasonable attorneys’ fees) resulting from any untrue statement of material fact contained in the Registration Statement, Prospectus or preliminary Prospectus or any
amendment thereof or supplement thereto or any omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, but only to the extent that such untrue statement or omission is contained in any
information or affidavit so furnished in writing by such Holder expressly for use therein; provided, that the obligation to indemnify shall be several, not joint and several, among such Holders of Registrable Securities, and the
liability of each such Holder of Registrable Securities shall be in proportion to and limited to the net proceeds received by such Holder from the sale of Registrable Securities pursuant to such Registration Statement. The Holders of Registrable
Securities shall indemnify the Underwriters, their officers, directors and each person who controls such Underwriters (within the meaning of the Securities Act) to the same extent as provided in the foregoing with respect to indemnification of the
Company. 
 4.3 Conduct of Indemnification Proceedings. Any person entitled to indemnification herein shall (i) give prompt
written notice to the indemnifying party of any claim with respect to which it seeks indemnification (provided that the failure to give prompt notice shall not impair any person’s right to indemnification hereunder to the extent such failure
has not materially prejudiced the indemnifying party), and (ii) unless in such indemnified party’s reasonable judgment a conflict of interest between such indemnified and indemnifying parties may exist with respect to such claim, permit
such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party. If such defense is assumed, the indemnifying party shall not be subject to any liability for any settlement made by the
indemnified party without its consent. An indemnifying party who is not entitled to, or elects not to, assume the defense of a claim shall not be obligated to pay the fees and expenses of more than one counsel for all parties indemnified by such
indemnifying party with respect to such claim, unless in the reasonable judgment of any indemnified party a conflict of interest may exist between such indemnified party and any other of such indemnified parties with respect to such claim. No
indemnifying party shall, without the consent of the indemnified party, consent to the entry of any judgment or enter into any settlement which cannot be settled in all respects by the payment of money (and such money is so paid by the indemnifying
party pursuant to the terms of such settlement) or which settlement 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. 
 4.4 Contribution. If the indemnification provided under Section 4.1 hereof from the indemnifying
party is unavailable or insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities and expenses referred to herein, then the indemnifying party, in lieu of indemnifying the indemnified party, shall
contribute to the amount paid or payable by the indemnified party as a result of such losses, claims, damages, liabilities and expenses in such proportion as is appropriate to reflect the relative fault of the indemnifying party and the indemnified
party, as well as any other relevant equitable considerations. The relative fault of the indemnifying party and indemnified party shall be determined by reference to, among other things, whether any action in question, including any untrue or
alleged untrue statement of a material fact or omission or alleged omission to state a material fact, was made by, or relates to information supplied by, such indemnifying party or indemnified party, and the indemnifying party’s and indemnified
party’s relative intent, knowledge, access to information and opportunity to correct or prevent such action; provided, that the liability of any Holder under this Section 4.4 shall be limited to the amount of
the net proceeds received by such Holder in such offering giving rise to such liability. The amount paid or payable by a party as a result of the losses or other liabilities referred to above shall be deemed to include, subject to the limitations
set forth in Sections 4.1-4.3 above, any legal or other fees, charges or expenses reasonably incurred by such party in connection with any investigation or proceeding. 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 this Section 4.4. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution pursuant to this Section 4.4 from any
person who was not guilty of such fraudulent misrepresentation. 







 4.4 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. The Company and each Holder of
Registrable Securities participating in an offering also agrees to make such provisions as are reasonably requested by any indemnified party for contribution to such party in the event the Company’s or such Holder’s indemnification is
unavailable for any reason. 
 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 Assignment; No Third Party Beneficiaries. 

6.1.1 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. 
 6.1.2 Prior to the expiration of the Lock-up Period, no Holder may assign
or delegate such Holder’s rights, duties or obligations under this Agreement, in whole or in part, except in connection with a transfer of Registrable Securities by such Holder to a Permitted Transferee, but only if such Permitted Transferee
agrees to become bound by the transfer restrictions set forth in this Agreement and other applicable letter agreements. 
 6.1.3 This
Agreement and the provisions hereof shall be binding upon and shall inure to the benefit of each of the parties and its successors and the permitted assigns of the Holders, which shall include Permitted Transferees. 

6.1.4 This Agreement shall not confer any rights or benefits on any persons that are not parties hereto, other than as expressly set forth in
this Agreement. 
 6.1.5 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). Any transfer or assignment made other than as provided in this Section 6.2 shall be null and void. 

6.2 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.

Attn: Jeffrey C. Selman, Esq. 

And to Holder, to the address set forth below such Holder’s name on Exhibit A hereto. 

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 a majority in
interest 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, that notwithstanding the foregoing, any amendment hereto or waiver hereof that adversely affects one Holder, solely in its capacity as a holder of the shares of capital stock of the Company, in a manner
that is materially different from the other Holders (in such capacity) shall require the consent of the Holder so affected. No course of dealing between any Holder or the Company and any other party hereto or any failure or delay on the part of a
Holder 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 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 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 Investors 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 Investors in the negotiation,
administration, performance or enforcement hereof. 
 6.13 Term. This Agreement shall terminate upon the earlier of (i) the

Section 4(a)(3) of the Securities Act and Rule 174 thereunder (or any successor rule promulgated thereafter by the Commission)), or (B) the Holders of all Registrable Securities are permitted to sell the Registrable Securities under Rule
144 (or any similar provision) under the Securities Act without limitation on the amount of securities sold or the manner of sale. The provisions of Section 3.5 and Article IV shall survive any termination.
