REGISTRATION


 


Section 2.1.       
Demand Registration.


 


2.1.1      
Request for Registration. Subject to the provisions of subsection 2.1.4 and Section 2.4 hereof,
at any time and from time to time (but subject to Article V), (i) Amber GT or (ii) the Perceptive Holders holding at least a majority
in interest of the then-outstanding number of Registrable Securities held by all Perceptive Holders (as the case may be, the “Demanding
Holders”), may make a written demand for Registration of all or part of their Registrable Securities on Form S-3 (or, if Form
S-3 is not available to be used by the Company at such time, on Form S-1 or another appropriate form permitting Registration of such Registrable
Securities for resale by such Demanding Holders), 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”).
The Company shall, within ten (10) days of the Company’s receipt of the Demand Registration, notify, in writing, all other Holders
of Registrable Securities of such demand, and each Holder of Registrable Securities who thereafter wishes to include all or a portion
of such Holder’s Registrable Securities in a Registration pursuant to a Demand Registration (each such Holder that includes all
or a portion of such Holder’s Registrable Securities in such Registration, a “Demand 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 Demand Requesting Holder(s) to the Company, such Demand Requesting Holder(s) shall
be entitled to have their 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 thirty (30) days immediately after the Company’s receipt of the Demand Registration,
the Registration of all Registrable Securities requested by the Demanding Holders and Demand Requesting Holders pursuant to such Demand
Registration; provided, that the Company shall not be obligated to effect any Registration under this subsection
2.1.1 if the Demanding Holders and Demand Requesting Holders propose to sell Registrable Securities with aggregate proceeds of
less than $25,000,000.


 






    6 


     


    

 


2.1.2      
Effective Registration. Notwithstanding the provisions of subsection 2.1.1 above or any other part of this
Agreement, a Registration pursuant to a Demand Registration shall not count as a Registration unless and until (i) the Registration Statement
filed with the Commission with respect to a Registration pursuant to a Demand 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, however,
that if, after such Registration Statement has been declared effective, an offering of Registrable Securities in a Registration pursuant
to a Demand Registration is subsequently interfered with by any stop order or injunction of the Commission, federal or state court or
any other governmental agency, the Registration Statement with respect to such Registration shall be deemed not to have been declared
effective for purposes of counting Registrations under subsection 2.1.1 above 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, but in no
event later than five (5) days, of such election; provided, further, however, that the Company shall
not be obligated or required to file another Registration Statement until the Registration Statement that has been previously filed with
respect to a Registration pursuant to a Demand Registration becomes effective or has been terminated.


 


2.1.3      
Underwritten Offering. Subject to the provisions of subsection 2.1.4 and Section 2.4 hereof,
if a majority-in-interest of the Demanding Holders advise the Company as part of their Demand Registration that the offering of the Registrable
Securities pursuant to such Demand Registration shall be in the form of an Underwritten Offering, then the right of such Demanding Holder
or Demand Requesting Holder (if any) to include its Registrable Securities in such Registration shall be conditioned upon such Holder’s
participation in 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 subsection 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, such Underwriter(s) to be reasonably acceptable to
the Company.


 


2.1.4      
Reduction of Underwritten Offering. If the managing Underwriter or Underwriters in an Underwritten Registration pursuant
to a Demand Registration, in good faith, advises the Company, the Demanding Holders and the Demand Requesting Holders (if any) in writing
that the dollar amount or number of Registrable Securities that the Demanding Holders and the Demand Requesting Holders (if any) desire
to sell, taken together with all other Common Stock or other equity securities that the Company desires to sell and the Common Stock,
if any, as to which a Registration has been requested pursuant to separate written contractual piggy-back registration rights held by
any other stockholders who desire to sell, exceeds the maximum dollar amount or maximum number of equity securities that can be sold in
the Underwritten 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 such 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 Demand Requesting Holders (if any) (pro rata based on the respective number of Registrable Securities
that each Demanding Holder and Demand Requesting Holder (if any) has requested be included in such Underwritten Registration and the aggregate
number of Registrable Securities that the Demanding Holders and Demand Requesting Holders have requested be included in such Underwritten
Registration (such proportion is referred to herein as “Pro Rata”)) that can be sold without exceeding the Maximum
Number of Securities; (ii) second, to the extent that the Maximum Number of Securities has not been reached under the foregoing clause
(i), Common Stock or other equity securities that the Company desires to sell, which can be sold without exceeding the Maximum Number
of Securities; and (iii) third, to the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (i)
and (ii), Common Stock or other equity securities of other persons or entities that the Company is obligated to register in a Registration
pursuant to separate written contractual arrangements with such persons and that can be sold without exceeding the Maximum Number of Securities.

case of a Registration under subsection 2.1.1 initiated by Amber GT or the Perceptive Holders, as the case may be, or
any Demand Requesting Holders (if any) shall have the right to withdraw from a Registration pursuant to such Demand Registration for any
or no reason whatsoever upon written notification to the Company and the Underwriter(s) (if any) of their intention to withdraw from such
Registration prior to the effectiveness of the Registration Statement filed with the Commission with respect to the Registration of their
Registrable Securities pursuant to such Demand Registration (or after such Registration Statement has been declared effective and is subsequently
interfered with by any stop order or injunction of the Commission, federal or state court or any other governmental agency).


 


Section 2.2.       
Piggyback Registration.


 


2.2.1      
Piggyback Rights. If 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, for its
own account or for the account of stockholders of the Company (other than pursuant to Sections 2.1 and 2.3 of
this Agreement), 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, (iv) filed on Form S-4 related to any merger, acquisition or business combination,
or (v) for a dividend reinvestment plan, then the Company shall give written notice of such proposed filing to all of the Holders of Registrable
Securities as soon as practicable but not less than ten (10) days before the anticipated filing date of such Registration Statement or
applicable Prospectus, which notice shall (A) 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(s), if any, in such offering, and (B) offer to all of the
Holders of Registrable Securities the opportunity to register the sale of such number of Registrable Securities as such Holders may request
in writing within five (5) days after receipt of such written notice (such Registration a “Piggyback Registration”).
The Company shall, in good faith, cause such Registrable Securities to be included in such Piggyback Registration and shall use its commercially
reasonable efforts to cause the managing Underwriter(s) of a proposed Underwritten Offering to permit the Registrable Securities requested
by the Holders pursuant to this subsection 2.2.1 to be included in a Piggyback Registration on the same terms and conditions
as any similar securities of the Company included in such Registration and to permit the sale or other disposition of such Registrable
Securities in accordance with the intended method(s) of distribution thereof. All such Holders proposing to distribute their Registrable
Securities through an Underwritten Offering under this subsection 2.2.1 shall enter into an underwriting agreement in

requested pursuant to Section 2.2.1 hereof, and (iii) the shares of Common Stock, if any, as to which Registration has
been requested pursuant to separate written contractual piggy-back registration rights of other stockholders of the Company, exceeds the

shall not include an offering of securities by the Company for the purpose of delivering cash to Amber GT or its transferee in connection
with an exchange of Amber GT Units pursuant to the LLC Agreement, such a Registration being considered to be a Registration by Amber GT
or its transferee, such Registration to be subject to the reduction procedures set forth in subsection 2.1.4 or subsection 2.3.6, as applicable),

to sell, which can be sold without exceeding the Maximum Number of Securities; (B) second, to the extent that the Maximum Number of Securities

Section 2.3.       
Resale Shelf Registration Rights.


 


2.3.1      
Registration Statement Covering Resale of Registrable Securities. The Company shall prepare and file or cause to be prepared
and filed with the Commission, no later than fifteen (15) days following the Closing Date (the “Filing Deadline”),
a Registration Statement for an offering to be made on a continuous basis pursuant to Rule 415 of the Securities Act or any successor
thereto registering the resale from time to time by Holders of all of the Registrable Securities held by the Holders (the “Resale
Shelf Registration Statement”). The Resale Shelf Registration Statement shall be on Form S-3 (or, if Form S-3 is not available
to be used by the Company at such time, on Form S-1 or another appropriate form permitting Registration of such Registrable Securities
for resale). If the Resale Shelf Registration Statement is initially filed on Form S-1 and thereafter the Company becomes eligible to
use Form S-3 for secondary sales, the Company shall, as promptly as practicable, cause such Resale Shelf Registration Statement to be
amended, or shall file a new replacement Resale Shelf Registration Statement, such that the Resale Shelf Registration Statement is on
Form S-3. The Company shall use commercially reasonable efforts to cause the Resale Shelf Registration Statement to be declared effective
as soon as possible after filing; provided, however, that the Company’s obligations to include the Registrable
Securities held by a Holder in the Resale Shelf Registration Statement are contingent upon such Holder furnishing in writing to the Company
such information regarding the Holder, the securities of the Company held by the Holder and the intended method of disposition of the
Registrable Securities as shall be reasonably requested by the Company to effect the registration of the Registrable Securities, and the
Holder shall execute such documents in connection with such registration as the Company may reasonably request that are customary of a
selling stockholder in similar situations. Once effective, the Company shall use commercially reasonable efforts to keep the Resale Shelf
Registration Statement and Prospectus included therein continuously effective and to be supplemented and amended to the extent necessary
to ensure that such Registration Statement is available or, if not available, to ensure that another Registration Statement is available,
under the Securities Act at all times until the earliest of (i) the date on which all Registrable Securities and other securities covered
by such Registration Statement have been disposed of in accordance with the intended method(s) of distribution set forth in such Registration
Statement and (ii) the date on which all Registrable Securities and other securities covered by such Registration Statement have ceased
to be Registrable Securities. The Registration Statement filed with the Commission pursuant to this subsection 2.3.1 shall
contain a prospectus in such form as to permit any Holder to sell such Registrable Securities pursuant to Rule 415 under the Securities
Act (or any successor or similar provision adopted by the Commission then in effect) at any time beginning on the effective date for such
Registration Statement (subject to lock-up restrictions provided in Section 5.1 of this Agreement), and shall provide
that such Registrable Securities may be sold pursuant to any method or combination of methods legally available to, and requested by,
Holders.


 


2.3.2      
Notification and Distribution of Materials. The Company shall notify the Holders in writing of the effectiveness of the
Resale Shelf Registration Statement as soon as practicable, and in any event within one (1) Business Day after the Resale Shelf Registration
Statement becomes effective, and shall furnish to them, without charge, such number of copies of the Resale Shelf Registration Statement
(including any amendments, supplements and exhibits), the Prospectus contained therein (including each preliminary prospectus and all
related amendments and supplements) and any documents incorporated by reference in the Resale Shelf Registration Statement or such other
documents as the Holders may reasonably request in order to facilitate the sale of the Registrable Securities in the manner described
in the Resale Shelf Registration Statement.


 






    11 


     


    

 


2.3.3      
Amendments and Supplements. Subject to the provisions of Section 2.3.1 above, the Company shall promptly
prepare and file with the Commission from time to time such amendments and supplements to the Resale Shelf Registration Statement and
Prospectus used in connection therewith as may be necessary to keep the Resale Shelf Registration Statement effective and to comply with
the provisions of the Securities Act with respect to the disposition of all the Registrable Securities. If any Resale Shelf Registration
Statement filed pursuant to Section 2.3.1 is filed on Form S-3 and thereafter the Company becomes ineligible to use Form
S-3 for secondary sales, the Company shall promptly notify the Holders of such ineligibility and use its commercially reasonable efforts
to file a shelf registration on an appropriate form as promptly as practicable to replace the shelf registration statement on Form S-3
and have such replacement Resale Shelf Registration Statement declared effective as promptly as practicable and to cause such replacement
Resale Shelf Registration Statement to remain effective, and to be supplemented and amended to the extent necessary to ensure that such
Resale Shelf Registration Statement is available or, if not available, that another Resale Shelf Registration Statement is available,
for the resale of all the Registrable Securities held by the Holders until all such Registrable Securities have ceased to be Registrable
Securities; provided, however, that at any time the Company once again becomes eligible to use Form S-3, the Company
shall cause such replacement Resale Shelf Registration Statement to be amended, or shall file a new replacement Resale Shelf Registration
Statement, such that the Resale Shelf Registration Statement is once again on Form S-3.


 


2.3.4      
SEC Cutback. Notwithstanding the registration obligations set forth in this Section 2.3, in the event the Commission
informs the Company that all of the Registrable Securities cannot, as a result of the application of Rule 415, be registered for resale
as a secondary offering on a single registration statement, the Company agrees to promptly (i) inform each of the Holders thereof and
use its commercially reasonable efforts to file amendments to the Resale Shelf Registration Statement as required by the Commission and/or
(ii) withdraw the Resale Shelf Registration Statement and file a new registration statement (a “New Registration Statement”)
on Form S-3, or if Form S-3 is not then available to the Company for such registration statement, on such other form available to register
for resale the Registrable Securities as a secondary offering; provided, however, that prior to filing such amendment
or New Registration Statement, the Company shall use its commercially reasonable efforts to advocate with the Commission for the registration
of all of the Registrable Securities in accordance with any publicly -available written or oral guidance, comments, requirements or requests
of the Commission staff (the “SEC Guidance”). Notwithstanding any other provision of this Agreement, if any SEC Guidance
sets forth a limitation on the number of Registrable Securities permitted to be registered on a particular Registration Statement as a
secondary offering (and notwithstanding that the Company used diligent efforts to advocate with the Commission for the registration of
all or a greater number of Registrable Securities), unless otherwise directed in writing by a Holder as to further limit its Registrable
Securities to be included on the Registration Statement, the number of Registrable Securities to be registered on such Registration Statement
will be reduced on a Pro Rata basis based on the total number of Registrable Securities held by the Holders, subject to a determination
by the Commission that certain Holders must be reduced first based on the number of Registrable Securities held by such Holders. In the
event the Company amends the Resale Shelf Registration Statement or files a New Registration Statement, as the case may be, under clauses
(i) or (ii) above, the Company will use its commercially reasonable efforts to file with the Commission, as promptly as allowed by Commission
or SEC Guidance provided to the Company or to registrants of securities in general, one or more registration statements on Form S-3 or
such other form available to register for resale those Registrable Securities that were not registered for resale on the Resale Shelf
Registration Statement, as amended, or the New Registration Statement.


 


2.3.5      
Underwritten Shelf Takedown. At any time and from time to time after a Resale Shelf Registration Statement has been declared
effective by the Commission, the Holders may request to sell all or any portion of the Registrable Securities in an underwritten offering
that is registered pursuant to the Resale Shelf Registration Statement (each, an “Underwritten Shelf Takedown”); provided, however,
that the Company shall only be obligated to effect an Underwritten Shelf Takedown if such offering shall include securities with a total
offering price (including piggyback securities and before deduction of underwriting discounts or commissions) reasonably expected to exceed,
in the aggregate, $15,000,000. All requests for Underwritten Shelf Takedowns shall be made by giving written notice to the Company at
least seven (7) days prior to the public announcement of such Underwritten Shelf Takedown, which shall specify the approximate number
of Registrable Securities proposed to be sold in the Underwritten Shelf Takedown and the expected price range (net of underwriting discounts
and commissions) of such Underwritten Shelf Takedown. Except in the case of a requested Underwritten Shelf Takedown in the form of a Block
Trade, following receipt of a request for an Underwritten Shelf Takedown, the Company shall promptly notify the other Holders of the request
and of their right to participate in the Underwritten Shelf Takedown, which shall specify the anticipated public announcement date. The
Company shall include in any Underwritten Shelf Takedown the securities requested to be included by any Holder (each a “Takedown
Requesting Holder”) at least 48 hours prior to the anticipated public announcement date of such Underwritten Shelf Takedown
set forth in the Company notice pursuant to written contractual piggyback registration rights of such Holder (including those set forth
herein). All such Holders proposing to distribute their Registrable Securities through an Underwritten Shelf Takedown under this subsection
2.3.5 shall enter into an underwriting agreement in customary form with the Underwriter(s) selected for such Underwritten Offering
by the majority-in-interest of the Takedown Requesting Holders initiating the Underwritten Shelf Takedown.


 






    12 


     


    

 


2.3.6      
Reduction of Underwritten Shelf Takedown. If the managing Underwriter(s) in an Underwritten Shelf Takedown, in good faith,
advise(s) the Company and the Takedown Requesting Holders in writing that the dollar amount or number of Registrable Securities that the
Takedown Requesting Holders desire to sell, taken together with all other shares of the Common Stock or other equity securities that the
Company desires to sell, exceeds the Maximum Number of Securities, then the Company shall include in such Underwritten Shelf Takedown,
as follows: (i) first, the Registrable Securities of the Takedown Requesting Holders, on a Pro Rata basis, that can be sold without exceeding
the Maximum Number of Securities; (ii) second, to the extent that the Maximum Number of Securities has not been reached under the foregoing
clause (i), the Common Stock or other equity securities, if any, that the Company desires to sell, which can be sold without exceeding
the Maximum Number of Securities; and (iii) third, to the extent that the Maximum Number of Securities has not been reached under the
foregoing clause (ii) and (iii) the Common Stock or other equity securities, if any, for the account of other persons or entities that
the Company is obligated to register pursuant to separate written contractual arrangements with such persons or entities, which can be
sold without exceeding the Maximum Number of Securities.


 


2.3.7      
Block Trades. If the Company shall receive a request from a Holder or Holders of Registrable Securities with an estimated
market value of at least $15,000,000 that the Company effect the sale of all or any portion of such Registrable Securities in an Underwritten
Shelf Takedown in the form of a Block Trade, then the Company shall, as expeditiously as possible, cooperate and effect the offering in
such Block Trade of the Registrable Securities for which such requesting Holder has requested such offering, without giving any effect
to any required notice periods or delivery of notices to any other Holders.

Underwritten Registration, in customary form and covering such matters of the type customarily covered by “cold comfort” letters

if any, obtain an opinion and negative assurance letter, dated such date, of counsel representing the Company for the purposes of such

Section 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 he, she or it has

Company that the use of the Prospectus may be resumed, provided that the Company hereby covenants to prepare and file any required supplement
or amendment correcting any Misstatement promptly after the time of such notice and, if necessary, to request the immediate effectiveness
thereof. If the filing, initial effectiveness or continued use of a Registration Statement or Prospectus included in any Registration
Statement at any time (a) would require the Company to make an Adverse Disclosure, (b) would require the inclusion in such Registration
Statement of financial statements that are unavailable to the Company for reasons beyond the Company’s control, or (c) in the good
faith judgment of the Board, would be materially detrimental to the Company, the Company shall have the right to defer the filing, initial
effectiveness or continued use of any Registration Statement pursuant to (a), (b) or (c) for a period of not more than ninety (90) consecutive
days or more than one hundred and twenty (120) total calendar days in any 12-month period. In the event the Company exercises its rights

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 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 customary legal opinions as reasonably requested. 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.


 


Section 3.6.       
Limitations on Registration Rights. Other than the registration rights granted to the purchasers under the Subscription Agreements
to be entered into on about the date hereof with certain investors relating to the private placement of shares of Common Stock as provided
for in the Business Combination Agreement, the Company represents and warrants that no person or entity, other than a Holder of Registrable
Securities, has any right to require the Company to register any securities of the Company for sale or to include such securities of the
Company in any Registration Statement filed by the Company for the sale of securities for its own account or for the account of any other
person or entity. The Company hereby agrees and covenants that it will not grant rights to register any Common Stock (or securities convertible
into or exchangeable for Common Stock) pursuant to the Securities Act that are more favorable, pari passu or senior to those granted to
the Holders hereunder without (a) the prior written consent of (i) Perceptive Holders holding at least a majority in interest of the then-outstanding
number of Registrable Securities held by all Perceptive Holders in their capacity as Perceptive Holders (provided the Perceptive Holders
or their Permitted Transferees hold Registrable Securities at such time) and (ii) Amber GT (provided Amber GT or its Permitted Transferees
hold Registrable Securities at such time); or (b) granting economically and legally equivalent rights to the Holders hereunder such that
the Holders shall receive the benefit of such more favorable or senior terms and/or conditions. 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 any conflict between any such agreement or agreements and this Agreement, the terms of this Agreement shall prevail.

INDEMNIFICATION AND CONTRIBUTION


 


Section 4.1.       
Indemnification.


 


4.1.1      
The Company agrees to indemnify, to the extent permitted by law, each Holder of Registrable Securities, its officers and directors
and agents and each person who controls such Holder (within the meaning of the Securities Act) against all losses, claims, damages, liabilities
and expenses (including attorneys’ fees) caused by any untrue or alleged untrue statement of material fact contained in any Registration
Statement, Prospectus or preliminary Prospectus or any amendment thereof or supplement thereto 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 such Holder expressly for use therein. The Company shall
indemnify the Underwriter(s), their officers and directors and each person who controls (within the meaning of the Securities Act) such
Underwriter(s) to the same extent as provided in the foregoing with respect to the indemnification of the Holder.


 


4.1.2      
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 (within the meaning of the Securities Act) the Company 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, however,
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 actually received by such Holder
from the sale of Registrable Securities pursuant to such Registration Statement. The Holders of Registrable Securities shall indemnify
the Underwriter(s), their officers, directors and each person who controls (within the meaning of the Securities Act) such Underwriter(s)
to the same extent as provided in the foregoing with respect to indemnification of the Company.


 






     18


     


    

 


4.1.3      
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, however, 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 (but such consent shall not be unreasonably withheld, conditioned or delayed).
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.


 


4.1.4      
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 (pursuant to subsection 4.1.5) to such party in the
event the Company’s or such Holder’s indemnification is unavailable for any reason.


 


4.1.5      
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, however,
that the liability of any Holder under this subsection 4.1.5 shall be limited to the amount of the net proceeds actually
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 subsections 4.1.1, 4.1.2 and 4.1.3 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 subsection 4.1.5 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 subsection 4.1.5. 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 subsection 4.1.5 from any person who was not guilty
of such fraudulent misrepresentation.


 






     19


     


    

 


4.1.6      
Notwithstanding the foregoing, to the extent that the provisions on indemnification and contribution contained in any underwriting
agreement entered into in connection with an underwritten public offering are in conflict with the foregoing provisions, the provisions
in the underwriting agreement shall control.

5 of the Sponsor Letter Agreement and Section 1.C.(i) of the Private Placement Shares Purchase Agreement, which provisions shall be of
no further force or effect as of the Closing Date.


 


Section 5.4.        Release
of Lock-Up Restrictions. Notwithstanding the other provisions set forth herein, the Board may, in its sole discretion, determine
to waive, amend, or repeal the restrictions set forth in Section 5.1 above, whether in whole or in part; provided,
that any such waiver, amendment or repeal shall (i) not make such restrictions more restrictive or apply for a longer period of time,
(ii) apply to each Holder equally, and (iii) require the unanimous approval of the directors present at any duly called meeting at which
a quorum is present. Notwithstanding anything to the contrary herein or in the LLC Agreement, any amendment, modification or waiver of,
or consent, approval or agreement under, the LLC Agreement (whether by the Board of Managers (as defined in the LLC Agreement), the Company
or otherwise) or any agreement with a Non-Corporation Member (as defined in the LLC Agreement) that (A) shortens, or has the effect of
shortening, the “Lock-up Period” (as defined in the LLC Agreement (as in effect following the consummation of the transactions
contemplated by the Business Combination Agreement)) (the “LLC Lock-Up Period”) with respect to a Non-Corporation
Member or (B) prior to the end of the LLC Lock-up Period, that allows, or has the effect of allowing, a Non-Corporation Member to transfer
its Common Units to any Person other than to a Permitted Transferee (as defined in the LLC Agreement (as in effect following the consummation
of the transactions contemplated by the Business Combination Agreement), and on the terms and subject to the conditions set forth therein)
shall, in each case, automatically have the effect of shortening the Lock-up Period hereunder for an equivalent amount of time, with
respect to clause (A), or immediately releasing all Holders from the transfer restrictions set forth in Section 5.1 hereunder,
with respect to clause (B).

Section 7.2.       
Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any rule
of law or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long
as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any party.
Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall
negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in a mutually
acceptable manner in order that the transactions contemplated hereby be consummated as originally contemplated to the fullest extent possible.


 


Section 7.3.       
Entire Agreement; Assignment.


 


7.3.1      
This Agreement constitutes the entire agreement among the parties with respect to the subject matter hereof and supersedes all
prior agreements and undertakings, both written and oral, among the parties, or any of them, with respect to the subject matter hereof.


 


7.3.2      
 This Agreement shall not be assigned (whether pursuant to a merger, by operation of law or otherwise), by any Holder without the
prior express written consent of the Company, except that (i) any Holder may, without consent, assign such Holder’s rights under
this Agreement to any transferee of Common Stock permitted under Section 5.2 and (ii) after the expiration of the Lock-Up
Period, any Holder may, without consent, assign its rights, in whole and not in part, to any transferee of its Registrable Securities
provided that such transferee continues to hold Registrable Securities following such Transfer (any such transferees in each of clause
(i) and (ii), a “Permitted Transferee”). 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. Any assignment made other than as provided in this Section 7.3 shall
be null and void.


 


Section 7.4.       
Parties in Interest. This Agreement shall be binding upon and inure solely to the benefit of each party hereto (and its respective
successors and permitted assigns), and nothing in this Agreement, express or implied, is intended to or shall confer upon any other person
any right, benefit or remedy of any nature whatsoever under or by reason of this Agreement.

Section 7.5.       
Governing Law. This Agreement shall be governed by, and construed in accordance with, the laws of the State of Delaware applicable
to contracts executed in and to be performed in that State. All legal actions and proceedings arising out of or relating to this Agreement
shall be heard and determined exclusively in any Delaware Chancery Court; provided, however, that if jurisdiction
is not then available in the Delaware Chancery Court, then any such legal action may be brought in any federal court located in the State
of Delaware or any other Delaware state court. The parties hereto hereby (a) irrevocably submit to the exclusive jurisdiction of the aforesaid
courts for themselves and with respect to their respective properties for the purpose of any action arising out of or relating to this
Agreement brought by any party hereto, and (b) agree not to commence any action relating thereto except in the courts described above
in Delaware, other than actions in any court of competent jurisdiction to enforce any judgment, decree or award rendered by any such court
in Delaware as described herein. Each of the parties further agrees that notice as provided herein shall constitute sufficient service
of process and the parties further waive any argument that such service is insufficient. Each of the parties hereby irrevocably and unconditionally
waives, and agrees not to assert, by way of motion or as a defense, counterclaim or otherwise, in any action arising out of or relating
to this Agreement or the transactions contemplated hereby, (x) any claim that it is not personally subject to the jurisdiction of the
courts in Delaware as described herein for any reason, (y) that it or its property is exempt or immune from jurisdiction of any such court
or from any legal process commenced in such courts (whether through service of notice, attachment prior to judgment, attachment in aid
of execution of judgment, execution of judgment or otherwise) and (z) that (i) the action in any such court is brought in an inconvenient
forum, (ii) the venue of such action is improper or (iii) this Agreement, or the subject matter hereof, may not be enforced in or by such
courts.


 


Section 7.6.       
Waiver of Jury Trial. EACH OF THE PARTIES HERETO HEREBY WAIVES TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW ANY RIGHT
IT MAY HAVE TO A TRIAL BY JURY WITH RESPECT TO ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS
AGREEMENT. EACH OF THE PARTIES HERETO (I) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY
OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THAT FOREGOING WAIVER AND (II) ACKNOWLEDGES
THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT AND THE TRANSACTIONS CONTEMPLATED HEREBY, AS APPLICABLE,
BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 7.6.


 


Section 7.7.       
Headings; Interpretation. The descriptive headings contained in this Agreement are included for convenience of reference only
and shall not affect in any way the meaning or interpretation of this Agreement. The parties have participated jointly in the negotiation
and drafting of this Agreement. If any ambiguity or question of intent arises, this Agreement will be construed as if drafted jointly
by the parties and no presumption or burden of proof will arise favoring or disfavoring any party because of the authorship of any provision
of this Agreement. Unless the context of this Agreement clearly requires otherwise, use of the masculine gender shall include the feminine
and neutral genders and vice versa, and the definitions of terms contained in this Agreement are applicable to the singular as well as
the plural forms of such terms. The words “includes” or “including” shall mean “including without limitation.”
The words “hereof,” “hereby,” “herein,” “hereunder” and similar terms in this Agreement
shall refer to this Agreement as a whole and not any particular section or article in which such words appear, the word “extent”
in the phrase “to the extent” shall mean the degree to which a subject or other thing extends and such phrase shall not mean
simply “if.” Any reference to a law shall include any rules and regulations promulgated thereunder, and shall mean such law
as from time to time amended, modified or supplemented. References herein to any contract (including this Agreement) mean such contract
as amended, supplemented or modified from time to time in accordance with the terms thereof.

Section 7.8.       
Counterparts. This Agreement may be executed and delivered (including by facsimile or portable document format (pdf) transmission)
in counterparts, and by the different parties hereto in separate counterparts, each of which when executed shall be deemed to be an original
but all of which taken together shall constitute one and the same agreement.


 


Section 7.9.       
Specific Performance. The parties hereto agree that irreparable damage would occur in the event any provision of this Agreement
was not performed in accordance with the terms hereof and that the parties shall be entitled to specific performance of the terms hereof,
in addition to any other remedy at law or in equity. Each of the parties hereby further waives (a) any defense in any action for specific
performance that a remedy at law would be adequate and (b) any requirement under any law to post security or a bond as a prerequisite
to obtaining equitable relief.


 


Section 7.10.    
Amendment. This Agreement may not be amended except by an instrument in writing signed by (i) the Company, (ii) Perceptive
Holders holding at least a majority in interest of the then-outstanding number of Registrable Securities held by all Perceptive Holders
in their capacity as Perceptive Holders (provided the Perceptive Holders or their Permitted Transferees hold Registrable Securities at
the time of such amendment), and (iii) Amber GT (provided Amber GT or its Permitted Transferees hold Registrable Securities at the time
of such amendment); provided, however, that notwithstanding the foregoing, any amendment hereto or waiver hereof that adversely
affects one Holder, solely in its capacity as a holder of Registrable Securities, in a manner that is materially different from the other
Holders (in such capacity) shall require the consent of the Holder so affected.


 


Section 7.11.   
Waiver. At any time, (i) the Company may (a) extend the time for the performance of any obligation or other act of any Holder,
(b) waive any inaccuracy in the representations and warranties of any Holder contained herein or in any document delivered by such Holder
pursuant hereto and (c) waive compliance with any agreement of such Holder or any condition to its own obligations contained herein. At
any time, (i) the Holders may (a) extend the time for the performance of any obligation or other act of the Company, (b) waive any inaccuracy
in the representations and warranties of the Company contained herein or in any document delivered by the Company pursuant hereto and
(c) waive compliance with any agreement of the Company or any condition to their own obligations contained herein. Any such extension
or waiver shall be valid if set forth in an instrument in writing signed by the party or parties to be bound thereby.


 






     25


     


    

 


Section 7.12.   
Further Assurances. At the request of the Company, in the case of any Holder, or at the request of any Holder, in the case
of the Company, and without further consideration, each party shall execute and deliver or cause to be executed and delivered such additional
documents and instruments and take such further action as may be reasonably necessary to consummate the transactions contemplated by this
Agreement.


 


Section 7.13.   
Prior Agreement Superseded. Pursuant to Section 5.6 of the Prior Agreement, the undersigned parties who are parties to such
Prior Agreement hereby terminate the Prior Agreement upon the consummation of the transactions set forth in the Business Combination Agreement,
with the intent and effect that the Prior Agreement shall hereby be replaced and superseded in its entirety by this Agreement.


 


Section 7.14.   
No Strict Construction. The language used in this Agreement shall be deemed to be the language chosen by the parties to express
their mutual intent and no rule of strict construction shall be applied against any party.
