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 on or after the date the Company consummates
the Business Combination, the Holders of at least thirty percent (30%) in interest of the then-outstanding number of
Registrable Securities (the “Demanding Holders”) may make a written demand for Registration under the
Securities Act 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”). 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 “Requesting Holder”) shall so notify the Company, in
writing, within five (5) day 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(s) to the Company, such 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 reasonably 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 Requesting Holders pursuant to such Demand Registration. Under no circumstances shall the Company be obligated to
effect more than an aggregate of three (3) Registrations pursuant to a Demand Registration under this subsection
2.1.1 with respect to any or all Registrable Securities; provided, however, 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 for resale 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 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,
further, 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, 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, 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 is subsequently 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 so 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 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 the majority-in-interest of the Demanding Holders initiating the Demand Registration.

 

2.1.4        Reduction
of Underwritten Offering. If the managing Underwriter(s) in an Underwritten Registration pursuant to a Demand Registration,
in good faith, advises the Company, the Demanding Holders and the Requesting Holders (if any) in writing that the dollar amount
or number of Registrable Securities that the Demanding Holders and the Requesting Holders (if any) desire to sell, taken together
with all other Common Stock or other equity securities that the Company desires to sell for its own account 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 Requesting Holders (if any) (pro rata based on the
respective number of Registrable Securities that each Demanding Holder and Requesting Holder (if any) has requested be included
in such Underwritten Registration and the aggregate number of Registrable Securities that the Demanding Holders and 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), the Common Stock or other equity securities that the Company desires
to sell for its own account, 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), the Common Stock
or other equity securities of other persons or entities that the Company is obligated to register for resale in a Registration
pursuant to separate written contractual arrangements with such persons and that can be sold without exceeding the Maximum Number
of Securities.

 

     

     

    

 

2.1.5        Demand
Registration Withdrawal. A majority-in-interest of the Demanding Holders initiating a Demand Registration or a majority-in-interest
of the Requesting Holders (if any), pursuant to a Registration under subsection 2.1.1 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.
Notwithstanding anything to the contrary in this Agreement, (i) the Company may effect any Underwritten Registration pursuant to
any then effective Registration Statement, including a Form S-3, that is then available for such offering and (ii) the Company
shall be responsible for the Registration Expenses incurred in connection with a Registration pursuant to a Demand Registration
prior to its withdrawal under this subsection 2.1.5.

 

2.2        Piggyback
Registration.

 

2.2.1        Piggyback
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, for its own account or for the account of stockholders
of the Company (or by the Company and by the stockholders of the Company including, without limitation, pursuant to Section 2.1
hereof), other than a Registration Statement (i) filed in connection with any employee stock option or other benefit plan,
(ii) for an exchange offer or offering of securities solely to the Company’s existing stockholders, (iii) for an
offering of debt that is convertible into equity securities of the Company or (iv) for a dividend reinvestment plan, then
the Company shall give written notice of such proposed filing to all of the Holders of Registrable Securities as soon as reasonably
practicable but not less than ten (10) days before the anticipated filing date of such Registration Statement, 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 resale 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 best 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 customary form with the Underwriter(s) selected for such Underwritten Offering by the Company.

 

2.2.2        Reduction
of Piggyback Registration. If the managing Underwriter(s) in an Underwritten Registration that is to be a Piggyback Registration,
in good faith, advises the Company and the Holders of Registrable Securities participating in the Piggyback Registration in writing
that the dollar amount or number of the Common Stock that the Company desires to sell, taken together with (i) the 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 (ii) the Registrable Securities as to which registration
has been requested pursuant Section 2.2 hereof, and (iii) the 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 Maximum Number of Securities, then:

 

(a) If the Registration is undertaken
for the Company’s account, the Company shall include in any such Registration (A) first, the Common Stock or other
equity securities that the Company desires to sell for its own account, which can be sold without exceeding the Maximum
Number of Securities; (B) second, to the extent that the Maximum Number of Securities has not been reached under the
foregoing clause (A), the Registrable Securities of Holders exercising their rights to register the resale of their
Registrable Securities pursuant to subsection 2.2.1 hereof, Pro Rata, which can be sold without exceeding the Maximum
Number of Securities; and (C) third, to the extent that the Maximum Number of Securities has not been reached under the
foregoing clauses (A) and (B), the Common Stock, if any, as to which Registration has been requested pursuant to written
contractual piggy-back registration rights of other stockholders of the Company, which can be sold without exceeding the
Maximum Number of Securities;

 

     

     

    

 

(b) If the Registration is pursuant to a
request by persons or entities other than the Holders of Registrable Securities, then the Company shall include in any such Registration
(A) first, the Common Stock or other equity securities, if any, of such requesting persons or entities, other than the Holders
of Registrable Securities, which can be sold without exceeding the Maximum Number of Securities; (B) second, to the extent
that the Maximum Number of Securities has not been reached under the foregoing clause (A), the Registrable Securities of Holders
exercising their rights to register the resale of their Registrable Securities pursuant to subsection 2.2.1, pro rata based
on the number of Registrable Securities that each Holder has requested be included in such Underwritten Registration and the aggregate
number of Registrable Securities that the Holders have requested to be included in such Underwritten Registration, which can be
sold without exceeding the Maximum Number of Securities; (C) third, to the extent that the Maximum Number of Securities has
not been reached under the foregoing clauses (A) and (B), the Common Stock or other equity securities that the Company desires
to sell for its own account, which can be sold without exceeding the Maximum Number of Securities; and (D) fourth, to the
extent that the Maximum Number of Securities has not been reached under the foregoing clauses (A), (B) and (C), the Common Stock
or other equity securities for the account of other persons or entities that the Company is obligated to register for resale pursuant
to separate written contractual arrangements with such persons or entities, which can be sold without exceeding the Maximum Number
of Securities.

 

2.2.3        Piggyback
Registration Withdrawal. Any Holder of Registrable Securities shall have the right to withdraw from a Piggyback Registration
for any or no reason whatsoever upon written notification to the Company and the Underwriter(s) (if any) of his, her or its intention
to withdraw from such Piggyback Registration prior to the effectiveness of the Registration Statement filed with the Commission
with respect to such Piggyback Registration (or in the case of an Underwritten Registration pursuant to Rule 415 under the Securities
Act, at least two business days prior to the time of pricing of the applicable offering). The Company (whether on its own good
faith determination or as the result of a request for withdrawal by persons pursuant to separate written contractual obligations)
may withdraw a Registration Statement filed with the Commission in connection with a Piggyback Registration at any time prior to
the effectiveness of such Registration Statement. Notwithstanding anything to the contrary in this Agreement, the Company shall
be responsible for the Registration Expenses incurred in connection with the Piggyback Registration prior to its withdrawal under
this subsection 2.2.3.

 

2.2.4        Unlimited Piggyback Registration
Rights. For purposes of clarity, any Registration effected pursuant to Section 2.2 hereof shall not be counted
as a Registration pursuant to a Demand Registration effected under Section 2.1 hereof.

 

2.3
       Registrations on Form S-3. The Holders of Registrable Securities may at any
time, and from time to time, request in writing that the Company, pursuant to Rule 415 under the Securities Act (or any
successor rule promulgated thereafter by the Commission), register the resale of any or all of their Registrable Securities
on Form S-3 or any similar short form registration statement that may be available at such time (“Form
S-3”), or if the Company is ineligible to use Form S-3, on Form S-1; provided, however,
that the Company shall not be obligated to effect such request through an Underwritten Offering. Within five (5) days of
the Company’s receipt of a written request from a Holder or Holders of Registrable Securities for a Registration on
Form S-3, the Company shall promptly give written notice of the proposed Registration on Form S-3 to all other Holders of
Registrable Securities, and each Holder of Registrable Securities who thereafter wishes to include all or a portion of such
Holder’s Registrable Securities in such Registration on Form S-3 shall so notify the Company, in writing, within ten
(10) days after the receipt by the Holder of the notice from the Company. As soon as reasonably practicable thereafter,
but not more than twelve (12) days after the Company’s initial receipt of such written request for a Registration
on Form S-3, the Company shall register the resale of 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 in the written notification given by such Holder or Holders; provided, however,
that the Company shall not be obligated to effect any such Registration pursuant to Section 2.3 hereof if the
Holders of Registrable Securities, together with the Holders of any other equity securities of the Company entitled to
inclusion in such Registration, propose to sell the Registrable Securities and such other equity securities (if any) at any
aggregate price to the public of less than $10,000,000. The Company shall maintain each registration statement pursuant to
this Section 2.3 (a “Shelf”) in accordance with the terms hereof, and shall prepare and file
with the SEC such amendments, including post-effective amendments, and supplements as may be necessary to keep such Shelf
continuously effective, available for use and in compliance with the provisions of the Securities Act until such time as
there are no longer any Registrable Securities included on such Shelf. In the event the Company files a Shelf on
Form S-1, the Company shall use its commercially reasonable efforts to convert the Form S-1 to a Form S-3 as
soon as reasonably practicable after the Company is eligible to use Form S-3. Registrations effected pursuant to this Section 2.3
shall not be counted as Demand Registrations effected pursuant to Section 2.1.

 

     

     

    

 

2.4        Restrictions
on Registration Rights. If (A) during the period starting with the date sixty (60) days prior to the Company’s
good faith estimate of the date of the filing of, and ending on a date one hundred and twenty (120) days after the effective
date of, a Company initiated Registration and provided that the Company has delivered written notice to the Holders prior to receipt
of a Demand Registration pursuant to subsection 2.1.1 and it continues to actively employ, in good faith, all reasonable
efforts to cause the applicable Registration Statement to become effective; (B) the Holders have requested an Underwritten
Registration and the Company and the Holders are unable to obtain the commitment of underwriters to firmly underwrite the offer;
or (C) in the good faith judgment of the Board such Registration would be materially detrimental to the Company and the Board
concludes as a result that it is essential to defer the filing of such Registration Statement at such time, then in each case the
Company shall furnish to such Holders a certificate signed by the Chairman of the Board stating that in the good faith judgment
of the Board it would be materially detrimental to the Company for such Registration Statement to be filed in the near future and
that it is therefore essential to defer the filing of such Registration Statement. In such event, the Company shall have the right
to defer such filing for a period of not more than thirty (30) days; provided, however, that the Company shall
not defer its obligation in this manner more than once in any 12-month period. Notwithstanding anything to the contrary contained
in this Agreement, no Registration shall be effected or permitted and no Registration Statement shall become effective, with respect
to any Registrable Securities held by any Holder, until after the expiration of the Founder Shares Lock-Up Period or the Private
Placement Lock-Up Period, as the case may be.

for resale on such Registration Statement or any Underwriter of Registrable Securities or as may be required by the rules, regulations
or instructions applicable to the registration form used by the Company or by the Securities Act or rules and regulations thereunder
to keep the Registration Statement effective until all Registrable Securities covered by such Registration Statement are sold in
accordance with the intended plan of distribution set forth in such Registration Statement or supplement to the Prospectus;

 

3.1.3       prior
to filing a Registration Statement or Prospectus, or any amendment or supplement thereto, furnish without charge to the Underwriter(s),
if any, and the Holders of Registrable Securities included in such Registration, and such Holders’ legal counsel, copies
of such Registration Statement as proposed to be filed, each amendment and supplement to such Registration Statement (in each case
including all exhibits thereto and documents incorporated by reference therein), the Prospectus included in such Registration Statement
(including each preliminary Prospectus), and such other documents as the Underwriter(s) and the Holders of Registrable Securities
included in such Registration or the legal counsel for any such Holders may reasonably request in order to facilitate the disposition
of the Registrable Securities owned by such Holders;

 

     

     

    

 

3.1.4        prior
to any public offering of Registrable Securities, use its best efforts to (i) register or qualify the Registrable Securities
covered by the Registration Statement under such securities or “blue sky” laws of such jurisdictions in the United
States as the Holders of Registrable Securities included in such Registration Statement (in light of their intended plan of distribution)
may request and (ii) take such action necessary to cause such Registrable Securities covered by the Registration Statement
to be registered with or approved by such other governmental authorities as may be necessary by virtue of the business and operations
of the Company and do any and all other acts and things that may be necessary or advisable to enable the Holders of Registrable
Securities included in such Registration Statement to consummate the disposition of such Registrable Securities in such jurisdictions;
provided, however, that the Company shall not be required to qualify generally to do business in any jurisdiction where it would
not otherwise be required to qualify or take any action to which it would be subject to general service of process or taxation
in any such jurisdiction where it is not then otherwise so subject;

 

3.1.5        cause
all such Registrable Securities to be listed on each securities exchange or automated quotation system on which similar securities
issued by the Company are then listed;

 

3.1.6        provide

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, 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, the Underwriter(s), if any, and any attorney or accountant retained by such Holders or Underwriter(s)
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, however, that such representatives or Underwriter(s) 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(s) may reasonably request, and 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 Underwriter(s), if any, covering such legal matters with respect to the Registration in respect of which
such opinion is being given as the participating Holders, placement agent, sales agent, or Underwriter may reasonably request and
as are customarily included in such opinions and negative assurance letters, and 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(s) 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 the resale of the 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(s) 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 participating 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 reasonably 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 a reporting
company 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.

 

     

     

    

 

ARTICLE IV 

INDEMNIFICATION AND CONTRIBUTION

 

4.1       Indemnification.

 

4.1.1        The
Company agrees to indemnify, to the extent permitted by law, each Holder of Registrable Securities, its officers, directors, agents
and each person who controls such Holder (within the meaning of the Securities Act) against all losses, claims, damages, liabilities
and out-of-pocket expenses (including, without limitation, reasonable attorneys’ fees) resulting from 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 such Underwriter(s) (within the meaning of the Securities Act) 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 the Company (within the meaning of the Securities Act) against any losses, claims, damages,
liabilities and out-of-pocket 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 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 such Underwriter(s) (within the meaning of the Securities Act) to the same extent as provided
in the foregoing with respect to indemnification of the Company.

 

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 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). 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 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 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.

5.2.1       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.

 

5.2.2        Prior
to the expiration of the Founder Shares Lock-up Period or the Private Placement Lock-up Period, as the case may be, 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.

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 5.2 shall be null and void.

 

     

     

    

 

5.3        Counterparts.

Securities at the time in question, compliance with any of the provisions, covenants and conditions set forth in this Agreement
may be waived, or any of such provisions, covenants or conditions may be amended or modified; provided, however,
that notwithstanding the foregoing, any amendment hereto or waiver hereof that adversely affects one Holder, 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.

 

5.6        Other
Registration Rights. The Company represents and warrants that no person, other than a Holder of Registrable Securities, has
any right to require the Company to register the offer, sale or resale of any securities of the Company for sale or to include
such securities of the Company in any Registration filed by the Company for the sale of securities for its own account or for the
account of any other person. Further, the Company represents and warrants that this Agreement supersedes any other registration
rights agreement or agreement with similar terms and conditions and in the event of a conflict between any such agreement or agreements
and this Agreement, the terms of this Agreement shall prevail.

Re: Administrative Services Agreement

 

Ladies and Gentlemen:

 

This letter agreement by and between Science Strategic Acquisition
Corp. Alpha, a Delaware corporation (the “Company”) and Science Partners Management, LLC, a Delaware
limited liability company (the “Services Provider”), dated as of the date hereof, will confirm our agreement
that, commencing on the date that securities of the Company are first listed on the Nasdaq Capital Market (the “Listing
Date”) and continuing until the earlier of the consummation by the Company of an initial business combination or
the Company’s liquidation (in each case as described in the Registration Statement on Form S-1 (File No. 333-251987) filed
with the Securities and Exchange Commission) (such earlier date hereinafter referred to as the “Termination Date”):

 

		1.	The Services Provider (and/or any of its affiliates designated by the Services Provider) shall make available to the Company,
at the address of the Services Provider referred to above (or any successor location or other existing office locations of the
Services Provider or any of its affiliates), office space and administrative and support services as may be reasonably requested
by the Company. In exchange therefor, the Company shall pay to the Services Provider, on the first day of each month, the sum of
$10,000 per month commencing on the Listing Date and continuing monthly thereafter until the Termination Date; and

 

		2.	The Services Provider hereby irrevocably waives any and all right, title, interest, causes of action and claims of any kind
or nature whatsoever (each, a “Claim”) in or to, and any and all right to seek payment of any amounts
due to it out of, the trust account established for the benefit of the public stockholders of the Company and into which substantially
all of the proceeds of the Company’s initial public offering will be deposited (the “Trust Account”),
and hereby irrevocably waives any Claim it presently has or may have in the future as a result of, or arising out of, this letter
agreement, which Claim would reduce, encumber or otherwise adversely affect the Trust Account or any monies or other assets in
the Trust Account, and further agrees not to seek recourse, reimbursement, payment or satisfaction of any Claim against the Trust
Account or any monies or other assets in the Trust Account for any reason whatsoever.

 

This letter agreement constitutes the entire agreement and
understanding of the parties hereto in respect of its subject matter and supersedes all prior understandings, agreements, or
representations by or among the parties hereto, written or oral, to the extent they relate in any way to the subject matter
hereof or the transactions contemplated hereby.

 

    1 

     

    

 

This letter agreement may not be amended, modified or waived
as to any particular provision, except by a written instrument executed by the parties hereto.

 

No party hereto may assign either this letter agreement or any
of its rights, interests, or obligations hereunder without the prior written approval of the other party, provided that the Services
Provider may assign this letter agreement or any of its rights, interests, or obligations hereunder to an affiliate without the
prior written approval of the Company. Any purported assignment in violation of this paragraph shall be void and ineffectual and
shall not operate to transfer or assign any interest or title to the purported assignee.

 

This letter agreement constitutes the entire relationship of
the parties hereto with respect to the subject matter described herein and any litigation between the parties (whether grounded
in contract, tort, statute, law or equity) shall be governed by and construed in accordance with the laws of the State of New York.

 

This letter agreement may be executed in one or more counterparts,
each of which shall for all purposes be deemed to be an original but all of which together shall constitute one and the same letter
agreement.
