2. REGISTRATION RIGHTS. 

2.1 Demand Registration. 

2.1.1 Request for Registration. At any time and from time to time on or after the date that the Company consummates a Business
Combination, the holders of a majority-in-interest of the then-outstanding number of Registrable Securities may make a written demand for Registration of all or part of
their Registrable Securities, which written demand shall describe the amount and type of securities to be included in such Registration and the intended method(s) of distribution thereof (such written demand 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 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 fifteen (15) 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
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injunction is removed, rescinded or otherwise terminated, and (ii) a majority-in-interest of the Demanding Holders thereafter elect to continue the offering;
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 Registrable 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 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) 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 Shares; (ii) second, to the extent that the Maximum Number of Shares 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 Shares; (iii) third, 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 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. 
 {N0382185 2 }

 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 Section 2.1.
 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 shareholders of the Company for their account (or by the Company and by shareholders 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 shareholders, (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 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 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 

{N0382185 2 } 

  
 4 













 b) If the registration is a “demand” registration undertaken at the demand of
persons other than either the holders of Registrable Securities, (A) 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 Shares;
(B) second, 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 that the Company desires to sell that can be sold without exceeding the Maximum
Number of Shares; (C) third, to the extent that the Maximum Number of Shares has not been reached under the foregoing clauses (A) and (B), 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, that can be sold without exceeding the Maximum Number of Shares; and (D) fourth, 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 withdrawal by persons making a demand pursuant to written contractual obligations) may withdraw a Registration Statement at any time prior to the effectiveness of such 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
promptly 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 other holder or holders joining in such request as are specified in a written request
given within fifteen (15) days after receipt of such written notice from the Company; provided, however, that the Company shall not be obligated to effect any such registration pursuant to this Section 2.3: (i) if Form S-3 is not available for such offering; or (ii) if 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 use its best efforts to, as expeditiously as possible
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

effective and use its best efforts to keep it effective for the period required by Section 3.1.3; provided, however, that the Company shall have the right to 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 President or Chairman 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 shareholders 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.

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 whether or not any such person is a party to any such claim or action and including any and all legal and other expenses incurred in
giving testimony or furnishing documents in response to a subpoena or otherwise; 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. Subject to the limitations set forth in Section 4.4.3 hereof, 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 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.

 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 advice 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 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. 

4.4.3 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) with respect to any action shall be entitled to contribution in such action 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 Rules may be amended from time to time, or any similar rule or regulation hereafter adopted by the Commission.
