hereto, dated as of the date hereof (as amended, restated, supplemented or otherwise modified from time to time, the “Purchase Agreement”). 

WHEREAS: 
 Pursuant to
that certain Business Combination Agreement by and among the Company, Apexigen, and Project Barolo Merger Sub Inc., a wholly owned subsidiary of the Company (“Merger Sub”) dated as of March 17, 2022, the Company and Apexigen

From and after the Merger, and subject to the terms and conditions set forth in the Purchase Agreement, the Company wishes to sell to the
Investor, and the Investor wishes to buy from the Company, up to Fifty Million Dollars ($50,000,000) of Purchase Shares, and to induce the Buyer to enter into the Purchase Agreement, the Company has agreed to provide certain registration rights
under the Securities Act of 1933, as amended, and the rules and regulations thereunder (collectively, the “Securities Act”), and applicable state securities laws. 

NOW, THEREFORE, in consideration of the promises and the mutual covenants contained herein and other good and valuable consideration,
the receipt and sufficiency of which are hereby acknowledged, the Company and the Buyer hereby agree as follows: 
 1. DEFINITIONS.

 As used in this Agreement, the following terms shall have the following meanings: 

(a) “Investor” means the Buyer, any transferee or assignee thereof to whom a Buyer assigns its rights under this Agreement in
accordance with Section 9 and who agrees to become bound by the provisions of this Agreement, and any transferee or assignee thereof to whom a transferee or assignee assigns its rights under this Agreement in accordance with Section 9 and
who agrees to become bound by the provisions of this Agreement. 
 (b) “Person” means any individual or entity including but
not limited to any corporation, a limited liability company, an association, a partnership, an organization, a business, an individual, a governmental or political subdivision thereof or a governmental agency. 

(c) “Register,” “Registered,” and “Registration” refer to a registration effected by
preparing and filing one or more registration statements of the Company in compliance with the Securities Act and pursuant to Rule 415 under the Securities Act or any successor rule providing for offering securities on a continuous basis
(“Rule 415”), and the declaration or ordering of effectiveness of such registration statement(s) by the United States Securities and Exchange Commission (the “SEC”). 

 (d) “Registrable Securities” means all of the Commitment Shares and all of
the Purchase Shares that may, from time to time, be issued or become issuable to the Investor under the Purchase Agreement (without regard to any limitation or restriction on purchases), and any and all shares of capital stock issued or issuable
with respect to the Purchase Shares or the Commitment Shares or the Purchase Agreement as a result of any stock split, stock dividend, recapitalization, exchange or similar event or otherwise, without regard to any limitation on purchases under the
Purchase Agreement. 
 (e) “Registration Statement” means one or more registration statements of the Company covering only
the sale of the Registrable Securities. 
 2. REGISTRATION. 

(a) Mandatory Registration. The Company shall, within thirty (30) days following the date of consummation of the Merger, file with
the SEC an initial Registration Statement covering the maximum number of Registrable Securities as shall be permitted to be included thereon in accordance with applicable SEC rules, regulations and interpretations so as to permit the resale of such
Registrable Securities by the Investor under Rule 415 under the Securities Act at then prevailing market prices (and not fixed prices), as mutually determined by both the Company and the Investor in consultation with their respective legal counsel,
subject to the aggregate number of authorized shares of the Company’s Common Stock then available for issuance in its Certificate of Incorporation and the Exchange Cap (as defined in the Purchase Agreement), provided, however, that the Company
may delay filing or suspend the use of any Registration Statement if the Company determines, upon advice of legal counsel, that in order for the registration statement to not contain a material misstatement or omission, an amendment thereto would be
needed, or if the Company’s Board of Directors, upon advice of legal counsel, reasonably believes that such filing or use could materially affect a bona fide business or financing transaction of the Company or would require premature disclosure
of information that could materially adversely affect the Company. The initial Registration Statement shall register only the Registrable Securities. The Investor and its counsel shall have a reasonable opportunity to review and comment upon such
Registration Statement and any amendment or supplement to such Registration Statement and any related prospectus prior to its filing with the SEC, and the Company shall give due consideration to all such comments. The Investor shall furnish all
information reasonably requested by the Company for inclusion therein. The Company shall use its commercially reasonable efforts to have the Registration Statement and any amendment declared effective by the SEC at the earliest practicable date. The
Company shall use commercially reasonable efforts to keep the Registration Statement effective pursuant to Rule 415 promulgated under the Securities Act and available for the resale by the Investor of all of the Registrable Securities covered
thereby at all times until the earlier of (i) the date on which the Investor shall have resold all the Registrable Securities covered thereby and no Available Amount (as defined in the Purchase Agreement) remains under the Purchase Agreement,
(ii) such Registrable Securities may be sold without Registration pursuant to Rule 144 without limitation as to volume and manner of sale restrictions and no Available Amount remains under the Purchase Agreement, (iii) six months after the
termination of the Purchase Agreement, and (iv) one year after the date on which no Available Amount remains under the Purchase Agreement (the “Registration Period”). The Registration Statement (including any amendments or
supplements thereto and prospectuses contained therein) shall not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein, or necessary to make the statements therein, in light of the
circumstances in which they were made, not misleading. 
 (b) Rule 424 Prospectus. The Company shall, as required by applicable
securities regulations, from time to time file with the SEC, pursuant to Rule 424 promulgated under the Securities Act, the prospectus and prospectus supplements, if any, to be used in connection with sales of the Registrable Securities under the
Registration Statement. The Investor and its counsel shall have a reasonable opportunity to review and comment upon such prospectus prior to its filing with the SEC, and the Company shall give due consideration to all such comments. The Investor
shall use its commercially reasonable efforts to comment upon such prospectus within one (1) Business Day from the date the Investor receives the substantially final pre-filing version of such prospectus.

  
 2 

 (c) Sufficient Number of Shares Registered. In the event the number of shares
available under the Registration Statement is insufficient to cover all of the Registrable Securities, the Company shall amend the Registration Statement or file a new Registration Statement (a “New Registration Statement”), so as
to cover all of such Registrable Securities (subject to the limitations set forth in Section 2(a)) as soon as practicable, but in any event not later than ten (10) Business Days after the necessity therefor arises, subject to any limits
that may be imposed by the SEC pursuant to Rule 415 under the Securities Act. The Company shall use its commercially reasonable efforts to cause such amendment and/or New Registration Statement to become effective as soon as practicable following
the filing thereof. 
 (d) Offering. If the staff of the SEC (the “Staff”) or the SEC seeks to characterize any
offering pursuant to a Registration Statement filed pursuant to this Agreement as constituting an offering of securities that does not permit such Registration Statement to become effective and be used for resales by the Investor under Rule 415 at
then-prevailing market prices (and not fixed prices), or if after the filing of the initial Registration Statement with the SEC pursuant to Section 2(a), the Company is otherwise required by the Staff or the SEC to reduce the number of
Registrable Securities included in such initial Registration Statement, then the Company shall reduce the number of Registrable Securities to be included in such initial Registration Statement (with the prior consent, which shall not be unreasonably
withheld, of the Investor as to the specific Registrable Securities to be removed therefrom) until such time as the Staff and the SEC shall so permit such Registration Statement to become effective and be used as aforesaid. In the event of any
reduction in Registrable Securities pursuant to this paragraph, the Company shall file one or more New Registration Statements in accordance with Section 2(c) until such time as all Registrable Securities have been included in Registration
Statements that have been declared effective and the prospectus contained therein is available for use by the Investor. Notwithstanding any provision herein or in the Purchase Agreement to the contrary, the Company’s obligations to register
Registrable Securities (and any related conditions to the Investor’s obligations) shall be qualified as necessary to comport with any requirement of the SEC or the Staff as addressed in this Section 2(d). 

3. RELATED OBLIGATIONS. 

With respect to the Registration Statement and whenever any Registrable Securities are to be registered pursuant to Section 2 including
on any New Registration Statement, the Company shall use its reasonable best efforts to effect the registration of the Registrable Securities in accordance with the intended method of disposition thereof and, pursuant thereto, the Company shall have
the following obligations: 
 (a) The Company shall prepare and file with the SEC such amendments (including post-effective amendments) and
supplements to any Registration Statement and the prospectus used in connection with such Registration Statement, which prospectus is to be filed pursuant to Rule 424 promulgated under the Securities Act, as may be necessary to keep the Registration
Statement or any New Registration Statement effective at all times during the Registration Period, and, during such period, comply with the provisions of the Securities Act in connection with the offer, issuance and sale of the Registrable
Securities. 
 (b) The Company shall permit the Investor to review and comment upon the final
pre-filing draft version of the Current Report at least two (2) Business Days prior to its filing with the SEC and, with respect to information regarding the Investor or the transaction contemplated
hereby, the Company shall not file the Current Report or the Registration Statement with the SEC in a form to which the Investor reasonably objects. The Investor shall use its reasonable best efforts to comment upon the Registration Statement or any
New Registration Statement and any amendments or supplements thereto within two (2) Business Days from the date the Investor receives the final version thereof. The Company shall furnish to the Investor, without charge any correspondence from the
SEC or the staff of the SEC to the Company or its representatives relating to the Registration Statement or any New Registration Statement. 

  
 3 

 (c) Upon request of the Investor, the Company shall furnish to the Investor,
(i) promptly after the same is prepared and filed with the SEC, at least one copy of such Registration Statement and any amendment(s) thereto, including financial statements and schedules, all documents incorporated therein by reference and all
exhibits, (ii) upon the effectiveness of any Registration Statement, a copy of the prospectus included in such Registration Statement and all amendments and supplements thereto (or such other number of copies as the Investor may reasonably
request) and (iii) such other documents, including copies of any preliminary or final prospectus, as the Investor may reasonably request from time to time in order to facilitate the disposition of the Registrable Securities owned by the
Investor. For the avoidance of doubt, any filing available to the Investor via the SEC’s live EDGAR system shall be deemed “furnished to the Investor” hereunder. 

(d) Upon the request of the Investor, the Company shall use commercially reasonable efforts to (i) register and qualify the resale by the
Investor of the Registrable Securities covered by a Registration Statement under such other securities or “blue sky” laws of such jurisdictions in the United States as the Investor reasonably requests, (ii) prepare and file in those
jurisdictions, such amendments (including post-effective amendments) and supplements to such registrations and qualifications as may be necessary to maintain the effectiveness thereof during the Registration Period, (iii) take such other
actions as may be necessary to maintain such registrations and qualifications in effect at all times during the Registration Period, and (iv) take all other actions reasonably necessary or advisable to qualify the Registrable Securities for
sale in such jurisdictions; provided, however, that the Company shall not be required in connection therewith or as a condition thereto to (x) qualify to do business in any jurisdiction where it would not otherwise be required to qualify but
for this Section 3(d), (y) subject itself to general taxation in any such jurisdiction, or (z) file a general consent to service of process in any such jurisdiction. The Company shall promptly notify the Investor who holds Registrable
Securities of the receipt by the Company of any notification with respect to the suspension of the registration or qualification of any of the Registrable Securities for sale under the securities or “blue sky” laws of any jurisdiction in
the United States or its receipt of actual notice of the initiation or threatening of any proceeding for such purpose. 
 (e) As promptly as
practicable after becoming aware of such event or facts, the Company shall notify the Investor in writing of the happening of any event or existence of such facts as a result of which the prospectus included in any Registration Statement, as then in
effect, includes an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading (provided
that in no event shall such notice contain any material, non-public information regarding the Company), and promptly prepare a supplement or amendment to such Registration Statement to correct such untrue
statement or omission, and deliver a copy of such supplement or amendment to the Investor (or such other number of copies as the Investor may reasonably request) , provided, however, that the Company may delay filing such supplement or amendment if
the Company’s Board of Directors, upon advice of legal counsel, reasonably believes that such filing or use could materially affect a bona fide business or financing transaction of the Company or would require premature disclosure of
information that could materially adversely affect the Company. The Company shall also promptly notify the Investor in writing (i) when a prospectus or any prospectus supplement or post-effective amendment has been filed, and when a
Registration Statement or any post-effective amendment has become effective (notification of such effectiveness shall be delivered to the Investor by email or facsimile on the same day of such effectiveness and by overnight mail), (ii) of any
request by the SEC for amendments or supplements to any Registration Statement or related prospectus or related information, and (iii) of the Company’s reasonable determination that a post-effective amendment to a Registration Statement
would be appropriate. 

  
 4 

 (f) The Company shall use its commercially reasonable efforts to prevent the issuance of any
stop order or other suspension of effectiveness of any registration statement, or the suspension of the qualification of any Registrable Securities for sale in any jurisdiction and, if such an order or suspension is issued, to obtain the withdrawal
of such order or suspension at the earliest possible moment and to notify the Investor of the issuance of such order and the resolution thereof or its receipt of actual notice of the initiation or threat of any proceeding for such purpose. 

(g) The Company shall (i) cause all the Registrable Securities to be listed on each securities exchange on which securities of the same
class or series issued by the Company are then listed, if any, if the listing of such Registrable Securities is then permitted under the rules of such exchange, or (ii) secure designation and quotation of all the Registrable Securities on the
Principal Market (as defined in the Purchase Agreement). The Company shall pay all fees and expenses in connection with satisfying its obligation under this Section 3. 

(h) The Company shall cooperate with the Investor to facilitate the timely preparation and delivery of certificates (not bearing any
restrictive legend) representing the Registrable Securities to be offered pursuant to any registration statement and enable such certificates to be in such denominations or amounts as the Investor may reasonably request and registered in such names
as the Investor may request. 
 (i) The Company shall at all times provide a transfer agent and registrar with respect to its Common Stock.

 (j) If reasonably requested in writing by the Investor, the Company shall (i) as soon as practicable after receipt of written notice
from the Investor, incorporate in a prospectus supplement or post-effective amendment such information as the Investor reasonably requests be included therein relating to the sale and distribution of Registrable Securities, including, without
limitation, information with respect to the number of Registrable Securities being sold, the purchase price being paid therefor and any other terms of the offering of the Registrable Securities; (ii) make all required filings of such prospectus
supplement or post-effective amendment as soon as practicable upon notification of the matters to be incorporated in such prospectus supplement or post-effective amendment; and (iii) supplement or make amendments to any Registration Statement
or New Registration Statement. 
 (k) The Company shall use its commercially reasonable efforts to cause the Registrable Securities covered
by any Registration Statement to be registered with or approved by such other governmental agencies or authorities as may be necessary to consummate the disposition of such Registrable Securities. 

(l) Within one (1) Business Day after any Registration Statement which includes the Registrable Securities is ordered effective by the
SEC, the Company shall deliver, and shall cause legal counsel for the Company to deliver, to the Transfer Agent for such Registrable Securities (with copies to the Investor) confirmation that such Registration Statement has been declared effective
by the SEC in the form attached hereto as Exhibit A, or such other form acceptable to the Company’s Transfer Agent. Thereafter, if requested by the Investor at any time, the Company shall require its counsel to deliver to the Investor a
written confirmation whether the Registration Statement has been declared effective under the Securities Act and if, to its knowledge, whether a stop order suspending the effectiveness of the Registration Statement has been issued or threatened by
the SEC. 
 (m) The Company shall take all other reasonable actions necessary to expedite and facilitate disposition by the Investor of
Registrable Securities pursuant to any Registration Statement.

 4. OBLIGATIONS OF THE INVESTOR. 

(a) The Company shall notify the Investor in writing of the information the Company reasonably requires from the Investor in connection with
any Registration Statement hereunder. The Investor shall as soon as practicable furnish to the Company such information regarding itself, the Registrable Securities held by it and the intended method of disposition of the Registrable Securities held
by it as shall be reasonably required to effect the registration of such Registrable Securities and shall execute such documents in connection with such registration as the Company may reasonably request. 

(b) The Investor agrees to cooperate with the Company as reasonably requested by the Company in connection with the preparation and filing of
any Registration Statement hereunder and any amendments and supplements thereto. 
 (c) The Investor agrees that, upon receipt of any notice
from the Company of the happening of any event or existence of facts of the kind described in Section 3(f) or the first sentence of Section 3(e), the Investor will immediately discontinue disposition of Registrable Securities pursuant to
any Registration Statement(s) covering such Registrable Securities until the Investor’s receipt of the copies a notice regarding the resolution or withdrawal of the stop order or suspension as contemplated by Section 3(f) or of the
supplemented or amended prospectus contemplated by Section 3(f) or the first sentence of 3(e). Notwithstanding anything to the contrary, the Company shall cause its Transfer Agent to promptly deliver shares of Common Stock without any
restrictive legend in accordance with the terms of the Purchase Agreement in connection with any sale of Registrable Securities with respect to which an Investor has entered into a contract for sale prior to the Investor’s receipt of a notice
from the Company of the happening of any event of the kind described in Section 3(f) or the first sentence of Section 3(e) and for which the Investor has not yet settled. 

5. EXPENSES OF REGISTRATION. 

All reasonable expenses (other than sales or brokerage commissions and fees incurred in connection with its sale of the Registrable Securities,
including the fees and disbursement of counsel for the Investor) incurred in connection with registrations, filings or qualifications pursuant to Sections 2 and 3, including, without limitation, all registration, listing and qualifications fees,
printers and accounting fees, and fees and disbursements of counsel for the Company, shall be paid by the Company. 
 6.
INDEMNIFICATION. 
 (a) To the fullest extent permitted by law, the Company will, and hereby does, indemnify, hold harmless and defend
the Investor, each Person, if any, who controls the Investor, the members, the directors, officers, partners, employees, agents, members, managers representatives of the Investor and each Person, if any, who controls the Investor within the meaning
of the Securities Act or the Securities Exchange Act of 1934, as amended (the “Exchange Act”) (each, an “Indemnified Person”), against any losses, claims, damages, liabilities, judgments, fines, penalties, charges,
costs, attorneys’ fees, amounts paid in settlement or expenses, joint or several, (collectively, “Claims”) incurred in investigating, preparing or defending any action, claim, suit, inquiry, proceeding, investigation or appeal
taken from the foregoing by or before any court or governmental, administrative or other regulatory agency, body or the SEC, whether pending or threatened, whether or not an indemnified party is or may be a party thereto (“Indemnified
Damages”), to which any of them may become subject insofar as such Claims (or actions or proceedings, whether commenced or threatened, in respect thereof) arise out of or are based upon: (i) any untrue statement or alleged untrue
statement of a material fact in the Registration Statement, any New Registration Statement or any post-effective amendment thereto, or the omission or alleged omission to state a material fact required to be stated therein or necessary to make the
statements therein not misleading, 

  
 6 

 
(ii) any untrue statement or alleged untrue statement of a material fact contained in the final prospectus (as amended or supplemented, if the Company files any amendment thereof or supplement
thereto with the SEC) or the omission or alleged omission to state therein any material fact necessary to make the statements made therein, in light of the circumstances under which the statements therein were made, not misleading, (iii) any
violation or alleged violation by the Company of the Securities Act, the Exchange Act, any other law, including, without limitation, any state securities law, or any rule or regulation thereunder relating to the offer or sale of the Registrable
Securities pursuant to the Registration Statement or any New Registration Statement or (iv) any material violation by the Company of this Agreement (the matters in the foregoing clauses (i) through (iv) being, collectively,
“Violations”). The Company shall reimburse each Indemnified Person promptly as such expenses are incurred and are due and payable, for any reasonable documented and
out-of-pocket legal fees or other reasonable expenses incurred by them in connection with investigating or defending any such Claim. Notwithstanding anything to the
contrary contained herein, the indemnification agreement contained in this Section 6(a): (i) shall not apply to a Claim by an Indemnified Person arising out of or based upon a Violation which occurs in reliance upon and in conformity with
information about the Investor furnished in writing to the Company by any Indemnified Person expressly for use in connection with the preparation of the Registration Statement, any New Registration Statement or any such amendment thereof or
supplement thereto or prospectus contained therein, if such Registration Statement, New Registration Statement or amendment thereof or supplement thereto or prospectus contained therein was timely made available by the Company pursuant to
Section 3(c) or Section 3(e); (ii) with respect to any superseded prospectus, shall not inure to the benefit of any Indemnified Person from whom the Indemnified Person asserting any such Claim purchased the Registrable Securities that are
the subject thereof (or to the benefit of any Indemnified Person controlling such Indemnified Person) if the untrue statement or omission of material fact contained in the superseded prospectus was corrected in the revised prospectus, as then
amended or supplemented, if such revised prospectus was timely made available by the Company pursuant to Section 3(c) or Section 3(e), and the Indemnified Person was promptly advised in writing not to use the incorrect prospectus prior to
the use giving rise to a violation and such Indemnified Person, notwithstanding such advice, used it; (iii) shall not be available to the extent such Claim is based on a failure of the Investor to deliver or to cause to be delivered the
prospectus made available by the Company, if such prospectus was timely made available by the Company pursuant to Section 3(c) or Section 3(e); and (iv) shall not apply to amounts paid in settlement of any Claim if such settlement is
effected without the prior written consent of the Company, which consent shall not be unreasonably withheld. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of the Indemnified Person and
shall survive the transfer of the Registrable Securities by the Investor pursuant to Section 9. 
 (b) In connection with the
Registration Statement or any New Registration Statement, the Investor agrees to indemnify, hold harmless and defend, to the same extent and in the same manner as is set forth in Section 6(a), the Company, each of its directors, each of its
officers who signs the Registration Statement or any New Registration Statement, each Person, if any, who controls the Company within the meaning of the Securities Act or the Exchange Act (collectively and together with an Indemnified Person, an
“Indemnified Party”), against any Claim or Indemnified Damages to which any of them may become subject, under the Securities Act, the Exchange Act or otherwise, insofar as such Claim or Indemnified Damages arise out of or are based
upon any Violation (which, in the case of this Section 6(b) shall include the failure on the part of the Investor to deliver a prospectus as required by this Agreement and applicable law), in each case to the extent, and only to the extent,
that such Violation occurs in reliance upon and in conformity with written information about the Investor set forth on Exhibit B attached hereto and furnished to the Company by the Investor expressly for use in connection with such
Registration Statement (it being hereby acknowledged and agreed that such written information, as the same may be updated from time to time in writing by the Investor, is the only written information furnished to the Company by or on behalf of the
Investor expressly for use in any Registration Statement); and, subject to Section 6(d), the Investor will reimburse any reasonable documented and out-of-pocket
legal or other expenses reasonably incurred 

  
 7 

 
by them in connection with investigating or defending any such Claim; provided, however, that the indemnity agreement contained in this Section 6(b) and the agreement with respect to
contribution contained in Section 7 shall not apply to amounts paid in settlement of any Claim if such settlement is effected without the prior written consent of the Investor, which consent shall not be unreasonably withheld; provided,
further, however, that the Investor shall be liable under this Section 6(b) for only that amount of a Claim or Indemnified Damages as does not exceed the net proceeds to the Investor as a result of the sale of Registrable Securities pursuant to
such Registration Statement. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of such Indemnified Party and shall survive the transfer of the Registrable Securities by the Investor pursuant to
Section 9. 
 (c) Promptly after receipt by an Indemnified Person or Indemnified Party under this Section 6 of notice of the
commencement of any action or proceeding (including any governmental action or proceeding) involving a Claim, such Indemnified Person or Indemnified Party shall, if a Claim in respect thereof is to be made against any indemnifying party under this
Section 6, deliver to the indemnifying party a written notice of the commencement thereof, and the indemnifying party shall have the right to participate in, and, to the extent the indemnifying party so desires, jointly with any other
indemnifying party similarly noticed, to assume control of the defense thereof with counsel mutually satisfactory to the indemnifying party and the Indemnified Person or the Indemnified Party, as the case may be; provided, however, that an
Indemnified Person or Indemnified Party shall have the right to retain its own counsel with the fees and expenses to be paid by the indemnifying party, if, in the reasonable opinion of counsel retained by the indemnifying party, the representation
by such counsel of the Indemnified Person or Indemnified Party and the indemnifying party would be inappropriate due to actual or potential differing interests between such Indemnified Person or Indemnified Party and any other party represented by
such counsel in such proceeding. 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, with advice of counsel, 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. The Indemnified Party or Indemnified Person shall cooperate fully with the indemnifying party in connection with any negotiation or defense of any such action or claim by the indemnifying party and shall furnish to the
indemnifying party all information reasonably available to the Indemnified Party or Indemnified Person which relates to such action or claim. The indemnifying party shall keep the Indemnified Party or Indemnified Person fully apprised at all times
as to the status of the defense or any settlement negotiations with respect thereto. No indemnifying party shall be liable for any settlement of any action, claim or proceeding effected without its written consent, provided, however, that the
indemnifying party shall not unreasonably withhold, delay or condition its consent. No indemnifying party shall, without the consent of the Indemnified Party or Indemnified Person, consent to entry of any judgment or enter into any settlement or
other compromise which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party or Indemnified Person of a release from all liability in respect to such claim or litigation. Following
indemnification as provided for hereunder, the indemnifying party shall be subrogated to all rights of the Indemnified Party or Indemnified Person with respect to all third parties, firms or corporations relating to the matter for which
indemnification has been made. The failure to deliver written notice to the indemnifying party within a reasonable time of the commencement of any such action shall not relieve such indemnifying party of any liability to the Indemnified Person or
Indemnified Party under this Section 6, except to the extent that the indemnifying party is prejudiced in its ability to defend such action. 

(d) The indemnification required by this Section 6 shall be made by periodic payments of the amount thereof during the course of the
investigation or defense, as and when bills are received or Indemnified Damages are incurred. 

  
 8 

 (e) The indemnity agreements contained herein shall be in addition to (i) any cause of
action or similar right of the Indemnified Party or Indemnified Person against the indemnifying party or others, and (ii) any liabilities the indemnifying party may be subject to pursuant to law. 

7. CONTRIBUTION. 
 To the
extent any indemnification by an indemnifying party is prohibited or limited by law, the indemnifying party agrees to make the maximum contribution with respect to any amounts for which it would otherwise be liable under Section 6 to the
fullest extent permitted by law; provided, however, that: (i) no seller of Registrable Securities guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any
seller of Registrable Securities who was not guilty of fraudulent misrepresentation; and (ii) contribution by any seller of Registrable Securities shall be limited in amount to the net amount of proceeds received by such seller from the sale of
such Registrable Securities. 
 8. REPORTS AND DISCLOSURE UNDER THE SECURITIES ACTS. 

With a view to making available to the Investor the benefits of Rule 144 promulgated under the Securities Act or any other similar rule or
regulation of the SEC that may at any time permit the Investor to sell securities of the Company to the public without registration (“Rule 144”), the Company agrees, at the Company’s sole expense, to: 

(a) make and keep public information available, as those terms are understood and defined in Rule 144; 

(b) file with the SEC in a timely manner all reports and other documents required of the Company under the Securities Act and the Exchange Act
so long as the Company remains subject to such requirements and the filing of such reports and other documents is required for the applicable provisions of Rule 144; 

(c) furnish to the Investor so long as the Investor owns Registrable Securities, promptly upon reasonable request, (i) a written statement
by the Company that it has complied with the reporting and or disclosure provisions of Rule 144, the Securities Act and the Exchange Act, (ii) a copy of the most recent annual or quarterly report of the Company and such other reports and
documents so filed by the Company, and (iii) such other information as may be reasonably requested to permit the Investor to sell such securities pursuant to Rule 144 without registration; and 

(d) take such additional action as is reasonably requested by the Investor to enable the Investor to sell the Registrable Securities pursuant
to Rule 144, including, without limitation, delivering all such legal opinions, consents, certificates, resolutions and instructions to the Company’s Transfer Agent as may be reasonably requested from time to time by the Investor and otherwise
fully cooperate with Investor and Investor’s broker to effect such sale of securities pursuant to Rule 144; provided, however, the Investor and its broker shall cooperate with the Company and its counsel and provide the necessary certificates,
instructions and other documents reasonably requested by the Company or its counsel in order to enable the Investor to sell the Registrable Securities pursuant to Rule 144. 

The Company agrees that damages may be an inadequate remedy for any breach of the terms and provisions of this Section 8 and that
Investor shall, whether or not it is pursuing any remedies at law, be entitled to seek equitable relief in the form of a preliminary or permanent injunction, without having to post any bond or other security, upon any breach or threatened breach of
any such terms or provisions.

 9. ASSIGNMENT OF REGISTRATION RIGHTS. 

The Company shall not assign this Agreement or any rights or obligations hereunder without the prior written consent of the Investor;
provided, however, that any transaction, whether by merger, reorganization, restructuring, consolidation, financing or otherwise, whereby the Company remains the surviving entity immediately after such transaction shall not be deemed an assignment.
The Investor may not assign its rights under this Agreement without the written consent of the Company, other than to an affiliate of the Investor controlled by Jonathan Cope or Josh Scheinfeld, in which case the assignee must agree in writing to be
bound by the terms and conditions of this Agreement. 
 10. AMENDMENT OF REGISTRATION RIGHTS. 

No provision of this Agreement may be amended or waived by the parties from and after the date that is one (1) Business Day immediately
preceding the initial filing of the Registration Statement with the SEC. Subject to the immediately preceding sentence, no provision of this Agreement may be (i) amended other than by a written instrument signed by both parties hereto or
(ii) waived other than in a written instrument signed by the party against whom enforcement of such waiver is sought. Failure of any party to exercise any right or remedy under this Agreement or otherwise, or delay by a party in exercising such

 Re: [__________] 

Ladies and Gentlemen: 
 We are counsel to
Brookline Capital Acquisition Corp., a Delaware corporation (the “Company”), and have represented the Company in connection with that certain Purchase Agreement, dated as of [___________], 2022 (the “Purchase
Agreement”), entered into by and between the Company and Lincoln Park Capital Fund, LLC (the “Buyer”) pursuant to which, among other things, the Company has agreed to issue to the Buyer shares of the Company’s Common
Stock, par value $0.0001 per share (the “Common Stock”), in an amount up to Fifty Million Dollars ($50,000,000) (the “Purchase Shares”), in accordance with the terms of the Purchase Agreement. In connection with the
transactions contemplated by the Purchase Agreement, the Company has registered with the U.S. Securities and Exchange Commission (the “SEC”) [__________] shares of Common Stock that may be issued and sold by the Company to
the Buyer from time to time (the “Purchase Shares”), 150,000 shares of Common Stock as Commitment Shares (the “Initial Commitment Shares”) and $1,500,000 worth of Common Stock as Additional Commitment Shares
(the “Additional Commitment Shares” and, collectively with the Initial Commitment Shares, the “Commitment Shares”). 

Pursuant to the Purchase Agreement, the Company also has entered into a Registration Rights Agreement, dated as of [____________], 2022 with
the Buyer (the “Registration Rights Agreement”) pursuant to which the Company agreed, among other things, to register the Purchase Shares and the Commitment Shares under the Securities Act of 1933, as amended (the
“Securities Act”). In connection with the Company’s obligations under the Purchase Agreement and the Registration Rights Agreement, on [_____________], 2022, the Company filed a Registration Statement (File No. 333-[_________]) (the “Registration Statement”) with the SEC relating to the resale of the Purchase Shares and the Commitment Shares by the Buyer. 

In connection with the foregoing, we advise you that a member of the SEC’s staff has advised us by telephone that the SEC has entered an
order declaring the Registration Statement effective under the Securities Act at __:__ am/pm on _______ __, 2022, and we have no knowledge, based solely on our review of the SEC’s “Stop Orders” web page
(http://sec.gov/litigation/stoporders.shtml), that any stop order suspending the Registration Statement’s effectiveness has been issued or that any proceedings for that purpose are pending before, or threatened by, the SEC.

DESCRIPTION OF SECURITIES

 

The following descriptions of securities of Pine Island Acquisition
Corporation (the “company,” “Pine Island,” “we” or “us”) is a summary and does not purport
to be complete. It is subject to and qualified in its entirety by reference to the company’s amended and restated certificate of
incorporation, bylaws and the company’s warrant agreement with Continental Stock Transfer & Trust Company, as warrant
agent (the “warrant agreement”), each of which is incorporated by reference as an exhibit to the Annual Report on Form 10-K
of which this Exhibit 4.5 is a part. We encourage you to read such documents for additional information.

 

Pursuant to our amended and restated certificate of incorporation,
our authorized capital stock consists of 200,000,000 shares of Class A common stock, $0.0001 par value, 20,000,000 shares of Class B
common stock, $0.0001 par value, and 1,000,000 shares of undesignated preferred stock, $0.0001 par value.

 

Units

 

Each unit has an offering price of $10.00 and consists of one share
of Class A common stock and one-third of one redeemable warrant. Each whole warrant entitles the holder thereof to purchase one
share of our Class A common stock at a price of $11.50 per share, subject to adjustment. Pursuant to the warrant agreement, a warrant
holder may exercise its warrants only for a whole number of shares of Class A common stock. This means that only a whole warrant
may be exercised at any given time by a warrant holder. No fractional warrants will be issued upon separation of the units and only whole
warrants will trade.

 

Common Stock

 

Common stockholders of record are entitled to one vote for each share
held on all matters to be voted on by stockholders. Other than with regard to our directors prior to our initial business combination
as described below under the heading, “Founder Shares,” holders of the Class A common stock and holders of the Class B
common stock will vote together as a single class on all matters submitted to a vote of our stockholders, including any vote in connection
with our initial business combination, except as required by law. Unless specified in our amended and restated certificate of incorporation
or bylaws, or as required by applicable provisions of the DGCL or applicable stock exchange rules, the affirmative vote of a majority
of our shares of common stock that are voted is required to approve any such matter voted on by our stockholders. Our board of directors
is divided into three classes, each of which will generally serve for a term of three years with only one class of directors being elected
in each year. There is no cumulative voting with respect to the election of directors, with the result that the holders of more than
50% of the shares voted for the election of directors can elect all of the directors. Our stockholders are entitled to receive ratable
dividends when, as and if declared by the board of directors out of funds legally available therefor. Prior to our initial business combination,
only holders of our founder shares will have the right to vote on the election of directors. Holders of our public shares will not be
entitled to vote on the election of directors during such time. In addition, prior to the completion of an initial business combination,
holders of a majority of our founder shares may remove a member of the board of directors for any reason.

 

Because our amended and restated certificate of incorporation authorizes
the issuance of up to only 200,000,000 shares of Class A common stock, if we were to enter into an initial business combination,
we may (depending on the terms of such an initial business combination) be required to increase the number of shares of Class A
common stock which we are authorized to issue at the same time as our stockholder vote on the initial business combination to the extent
we seek stockholder approval in connection with our initial business combination.

 

In accordance with the NYSE corporate governance requirements, we
are not required to hold an annual meeting until no later than one full year after our first fiscal year end following our listing on
the NYSE. Under Section 211(b) of the DGCL, we are, however, required to hold an annual meeting of stockholders for the purposes
of electing directors in accordance with our bylaws, unless such election is made by written consent in lieu of such a meeting. We may
not hold an annual meeting of stockholders to elect new directors prior to the consummation of our initial business combination, and
thus we may not be in compliance with Section 211(b) of the DGCL, which requires an annual meeting. Therefore, if our stockholders
want us to hold an annual meeting prior to the consummation of our initial business combination, they may attempt to force us to hold
one by submitting an application to the Delaware Court of Chancery in accordance with Section 211(c) of the DGCL.

 

    

    

    

 

We will provide our public stockholders with the opportunity to redeem
all or a portion of their public shares upon (i) the completion of our initial business combination or (ii) a stockholder vote
to approve an amendment to our amended and restated certificate of incorporation (A) to modify the substance or timing of our obligation
to allow redemption in connection with our initial business combination or to redeem 100% of our public shares if we do not complete
our initial business combination within 24 months from the closing of our initial public offering or (B) with respect to any other
provision relating to stockholders’ rights or pre-initial business combination activity. Such redemptions, if any, will be made
at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the trust account as of two business days prior
to the event triggering the right to redeem, including interest earned on the funds held in the trust account and not previously released
to us to pay our franchise and income taxes, divided by the number of then outstanding public shares, subject to the limitations described
herein. The per-share amount we will distribute to investors who properly redeem their shares will not be reduced by the deferred underwriting
commissions we will pay to the underwriters. Our initial stockholders, officers and directors have entered into a letter agreement with
us, pursuant to which they have agreed to waive their redemption rights with respect to any founder shares and any public shares held
by them in connection with the completion of our initial business combination, or a stockholder vote to approve an amendment to our amended
and restated certificate of incorporation, as described above. Unlike many blank check companies that hold stockholder votes and conduct
proxy solicitations in conjunction with their initial business combinations and provide for related redemptions of public shares for
cash upon completion of such initial business combinations even when a vote is not required by law, if a stockholder vote is not required
by law and we do not decide to hold a stockholder vote for business or other reasons, we will, pursuant to our amended and restated certificate
of incorporation, conduct the redemptions pursuant to the tender offer rules of the Securities and Exchange Commission (“SEC”),
and file tender offer documents with the SEC prior to completing our initial business combination. Our amended and restated certificate
of incorporation requires these tender offer documents to contain substantially the same financial and other information about the initial
business combination and the redemption rights as is required under the SEC’s proxy rules. If, however, a stockholder approval
of the transaction is required by law, or we decide to obtain stockholder approval for business or other reasons, we will, like many
blank check companies, offer to redeem shares in conjunction with a proxy solicitation pursuant to the proxy rules and not pursuant
to the tender offer rules. If we seek stockholder approval, we will complete our initial business combination only if a majority of the
outstanding shares of common stock voted are voted in favor of the initial business combination. A quorum for such meeting will consist
of the holders present in person or by proxy of shares of outstanding capital stock of the company representing a majority of the voting
power of all outstanding shares of capital stock of the company entitled to vote at such meeting.

 

However, the participation of our sponsor, officers, directors, advisors
or their affiliates in privately-negotiated transactions, if any, could result in the approval of our initial business combination even
if a majority of our public stockholders vote, or indicate their intention to vote, against such business combination. For purposes of
seeking approval of the majority of our outstanding shares of common stock voted, non-votes will have no effect on the approval of our
initial business combination once a quorum is obtained. We intend to give approximately 30 days (but not less than 10 days nor more than
60 days) prior written notice of any such meeting, if required, at which a vote shall be taken to approve our initial business combination.
These quorum and voting thresholds, and the voting agreements of our initial stockholders, may make it more likely that we will consummate
our initial business combination.

 

If we seek stockholder approval of our initial business combination
and we do not conduct redemptions in connection with our initial business combination pursuant to the tender offer rules, our amended
and restated certificate of incorporation provides that a public stockholder, together with any affiliate of such stockholder or any
other person with whom such stockholder is acting in concert or as a “group” (as defined under Section 13 of the Exchange
Act), will be restricted from redeeming its shares with respect to more than an aggregate of 15% of the shares of common stock sold in
our initial public offering, which we refer to as the Excess Shares. However, we would not be restricting our stockholders’ ability
to vote all of their shares (including Excess Shares) for or against our initial business combination. Our stockholders’ inability
to redeem the Excess Shares will reduce their influence over our ability to complete our initial business combination, and such stockholders
could suffer a material loss in their investment if they sell such Excess Shares on the open market. Additionally, such stockholders
will not receive redemption distributions with respect to the Excess Shares if we complete the initial business combination. And, as
a result, such stockholders will continue to hold that number of shares exceeding 15% and, in order to dispose such shares would be required
to sell their stock in open market transactions, potentially at a loss.

 

If we seek stockholder approval in connection with our initial business
combination, pursuant to the letter agreement, our initial stockholders, officers and directors have agreed to vote their founder shares
and any public shares purchased during or after our initial public offering (including in open market and privately negotiated transactions)
in favor of our initial business combination.

 

    

    

    

 

Pursuant to our amended and restated certificate of incorporation,
if we do not complete our initial business combination within 24 months from the closing of our initial public offering or during any
extended time that we have to consummate a business combination beyond 24 months as a result of a stockholder vote to amend our amended
and restated certificate of incorporation (“Extension Period”), we will (i) cease all operations except for the purpose
of winding up, (ii) as promptly as reasonably possible but no more than ten business days thereafter subject to lawfully available
funds therefor, redeem the public shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the
trust account including interest earned on the funds held in the trust account and not previously released to us to pay our franchise
and income taxes (less up to $100,000 of interest to pay dissolution expenses), divided by the number of then outstanding public shares,
which redemption will completely extinguish public stockholders’ rights as stockholders (including the right to receive further
liquidating distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption,
subject to the approval of our remaining stockholders and our board of directors, dissolve and liquidate, subject in each case to our
obligations under Delaware law to provide for claims of creditors and the requirements of other applicable law. Our initial stockholders,
officers and directors have entered into a letter agreement with us, pursuant to which they have agreed to waive their rights to liquidating
distributions from the trust account with respect to any founder shares held by them if we fail to complete our initial business combination
within 24 months from the closing of our initial public offering or during any Extension Period. However, if our initial stockholders
acquire public shares in or after our initial public offering, they will be entitled to liquidating distributions from the trust account
with respect to such public shares if we fail to complete our initial business combination within the prescribed time period.

 

In the event of a liquidation, dissolution or winding up of the company
after an initial business combination, our stockholders are entitled to share ratably in all assets remaining available for distribution
to them after payment of liabilities and after provision is made for each class of stock, if any, having preference over the common stock.
Our stockholders have no preemptive or other subscription rights. There are no sinking fund provisions applicable to the common stock,
except that we will provide our stockholders with the opportunity to redeem their public shares for cash equal to their pro rata share
of the aggregate amount then on deposit in the trust account, upon the completion of our initial business combination, subject to the
limitations described herein.

 

Founder Shares

 

The founder shares are identical to the shares of Class A common
stock, and holders of founder shares have the same stockholder rights as public stockholders, except that (i) the founder shares
are subject to certain transfer restrictions, as described in more detail below, (ii) our initial stockholders, officers and directors
have entered into a letter agreement with us, pursuant to which they have agreed (A) to waive their redemption rights with respect
to any founder shares and any public shares held by them in connection with the completion of our initial business combination, (B) to
waive their redemption rights with respect to their founder shares and public shares in connection with a stockholder vote to approve
an amendment to our amended and restated certificate of incorporation (x) to modify the substance or timing of our obligation to
allow redemption in connection with our initial business combination or to redeem 100% of our public shares if we do not complete our
initial business combination within 24 months from our initial public offering or during any Extension Period or (y) with respect
to any other provision relating to stockholders’ rights or pre-initial business combination activity and (C) to waive their
rights to liquidating distributions from the trust account with respect to any founder shares held by them if we fail to complete our
initial business combination within 24 months from the closing of our initial public offering or during any Extension Period, although
they will be entitled to liquidating distributions from the trust account with respect to any public shares they hold if we fail to complete
our initial business combination within such time period, (iii) the founder shares are shares of our Class B common stock that
will automatically convert into shares of our Class A common stock at the time of our initial business combination, or at any time
prior thereto at the option of the holder, on a one-for-one basis, subject to adjustment as described herein, and (iv) are entitled
to registration rights. If we submit our initial business combination to our public stockholders for a vote, our initial stockholders,
officers and directors have agreed pursuant to the letter agreement to vote any founder shares held by them and any public shares purchased
during or after our initial public offering (including in open market and privately negotiated transactions) in favor of our initial
business combination.

 

    

    

    

 

The shares of Class B common stock will automatically convert
into shares of Class A common stock at the time of our initial business combination on a one-for-one basis (subject to adjustment
for stock splits, stock dividends, reorganizations, recapitalizations and the like), and subject to further adjustment as provided herein.
In the case that additional shares of Class A common stock, or equity-linked securities, are issued or deemed issued in excess of
the amounts offered in connection with our initial public offering and related to the closing of the initial business combination, the
ratio at which shares of Class B common stock shall convert into shares of Class A common stock will be adjusted (unless the
holders of a majority of the outstanding shares of Class B common stock agree to waive such adjustment with respect to any such
issuance or deemed issuance) so that the number of shares of Class A common stock issuable upon conversion of all shares of Class B
common stock will equal, in the aggregate, on an as-converted basis, 20% of the sum of (i) the total number of all shares of common
stock outstanding upon completion of our initial public offering, plus (ii) all shares of Class A common stock and equity-linked
securities issued or deemed issued in connection with the initial business combination (excluding any shares of Class A common stock
or equity-linked securities issued, or to be issued, to any seller in the initial business combination, and any private placement-equivalent
warrants issued to our sponsor or its affiliates upon conversion of loans made to us). We cannot determine at this time whether a majority
of the holders of our Class B common stock at the time of any future issuance would agree to waive such adjustment to the conversion
ratio. They may waive such adjustment due to (but not limited to) the following: (i) closing conditions which are part of the agreement
for our initial business combination; (ii) negotiation with Class A stockholders on structuring an initial business combination;
or (iii) negotiation with parties providing financing which would trigger the anti-dilution provisions of the Class B common
stock If such adjustment is not waived, the issuance would not reduce the percentage ownership of holders of our Class B common
stock, but would reduce the percentage ownership of holders of our Class A common stock. If such adjustment is waived, the issuance
would reduce the percentage ownership of holders of both classes of our common stock. Holders of founder shares may also elect to convert
their shares of Class B common stock into an equal number of shares of Class A common stock, subject to adjustment as provided
above, at any time. Securities could be “deemed issued” for purposes of the conversion rate adjustment if such shares are
issuable upon the conversion or exercise of convertible securities, warrants or similar securities.

 

With certain limited exceptions, the founder shares are not transferable,
assignable or salable (except to our officers and directors and other persons or entities affiliated with our sponsor, each of whom will
be subject to the same transfer restrictions) until the earlier of (A) one year after the completion of our initial business combination
or (B) subsequent to our initial business combination, (x) if the last reported sale price of our Class A common stock
equals or exceeds $12.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for
any 20 trading days within any 30-trading day period commencing at least 150 days after our initial business combination, or (y) the
date on which we complete a liquidation, merger, capital stock exchange, reorganization or other similar transaction that results in
all of our stockholders having the right to exchange their shares of common stock for cash, securities or other property.

 

Prior to our initial business combination, only holders of our founder
shares will have the right to vote on the election of directors. Holders of our public shares will not be entitled to vote on the election
of directors during such time. In addition, prior to the completion of an initial business combination, holders of a majority of our
founder shares may remove a member of the board of directors for any reason. These provisions of our amended and restated certificate
of incorporation may only be amended by a resolution passed by a majority of our Class B common stock. With respect to any other
matter submitted to a vote of our stockholders, including any vote in connection with our initial business combination, except as required
by law, holders of our founder shares and holders of our public shares will vote together as a single class, with each share entitling
the holder to one vote.

 

    

    

    

 

Preferred Stock

 

Our amended and restated certificate of incorporation provides that
shares of preferred stock may be issued from time to time in one or more series. Our board of directors is authorized to fix the voting
rights, if any, designations, powers, preferences, the relative, participating, optional or other special rights and any qualifications,
limitations and restrictions thereof, applicable to the shares of each series. Our board of directors is able to, without stockholder
approval, issue preferred stock with voting and other rights that could adversely affect the voting power and other rights of the holders
of the common stock and could have anti-takeover effects. The ability of our board of directors to issue preferred stock without stockholder
approval could have the effect of delaying, deferring or preventing a change of control of us or the removal of existing management.
We have no preferred stock outstanding at the date hereof. Although we do not currently intend to issue any shares of preferred stock,
we cannot assure you that we will not do so in the future.

 

Redeemable Warrants

 

Public Stockholders’ Warrants

 

Each whole warrant entitles the registered holder to purchase one
share of our Class A common stock at a price of $11.50 per share, subject to adjustment as discussed below, at any time commencing
on the later of 12 months from the closing of our initial public offering or 30 days after the completion of our initial business combination.
Pursuant to the warrant agreement, a warrant holder may exercise its warrants only for a whole number of shares of Class A common
stock. This means that only a whole warrant may be exercised at any given time by a warrant holder. No fractional warrants will be issued
upon separation of the units and only whole warrants will trade. The warrants will expire five years after the completion of our initial
business combination, at 5:00 p.m., New York City time, or earlier upon redemption or liquidation.

 

We will not be obligated to deliver any shares of Class A common
stock pursuant to the exercise of a warrant and will have no obligation to settle such warrant exercise unless a registration statement
under the Securities Act of 1933, as amended (the “Securities Act”) with respect to the shares of Class A common stock
underlying the warrants is then effective and a prospectus relating thereto is current, subject to our satisfying our obligations described
below with respect to registration. No warrant will be exercisable and we will not be obligated to issue shares of Class A common
stock upon exercise of a warrant unless Class A common stock issuable upon such warrant exercise has been registered, qualified
or deemed to be exempt under the securities laws of the state of residence of the registered holder of the warrants. In the event that
the conditions in the two immediately preceding sentences are not satisfied with respect to a warrant, the holder of such warrant will
not be entitled to exercise such warrant and such warrant may have no value and expire worthless. In no event will we be required to
net cash settle any warrant. In the event that a registration statement is not effective for the exercised warrants, the purchaser of
a unit containing such warrant will have paid the full purchase price for the unit solely for the share of Class A common stock
underlying such unit.

 

We have agreed that as soon as practicable, but in no event later
than 15 business days after the closing of our initial business combination, we will use our commercially reasonable efforts to file
with the SEC a registration statement covering the shares of Class A common stock issuable upon exercise of the warrants. We will
use our commercially reasonable efforts to cause such registration statement to become effective within 60 business days after the closing
of our initial business combination and to maintain a current prospectus relating to those shares of Class A common stock until
the warrants expire or are redeemed, as specified in the warrant agreement. If a registration statement covering the shares of Class A
common stock issuable upon exercise of the warrants is not effective by the 60th business day after the closing of our initial business
combination, warrant holders may, until such time as there is an effective registration statement and during any period when we will
have failed to maintain an effective registration statement, exercise warrants on a “cashless basis” in accordance with Section 3(a)(9) of
the Securities Act or another exemption. In such event, each holder would pay the exercise price by surrendering the warrants for that
number of shares of Class A common stock equal to the lesser of (A) the quotient obtained by dividing (x) the product
of the number of shares of Class A common stock underlying the warrants, multiplied by the excess of the “fair market value”
of our Class A common stock over the exercise price of the warrants by (y) the fair market value and (B) 0.361 per whole
warrant. The “fair market value” as used in this paragraph shall mean the average last reported sale price of the Class A
common stock for the ten trading days ending on the third trading day prior to the date on which the notice of exercise is received by
the warrant agent. If that exemption, or another exemption, is not available, holders will not be able to exercise their warrants on
a cashless basis.

 

    

    

    

 

Redemption
of warrants when the price per share of Class A common stock equals or exceeds $18.00. Once the warrants become exercisable,
we may redeem the outstanding warrants (except as described herein with respect to the private placement warrants):

 

	 	•	in whole and not in part;

 

	 	•	at a price of $0.01 per warrant;

 

	 	•	upon a minimum of 30 days’ prior written notice
    of redemption to each warrant holder; and

 

	 	•	if, and only if, the last reported sale price of the
    Class A common stock for any 20 trading days within a 30-trading day period ending three trading days before we send the notice
    of redemption to the warrant holders (which we refer to as the “Reference Value”) equals or exceeds $18.00 per share
    (as adjusted for adjustments to the number of shares issuable upon exercise or the exercise price of a warrant as described under
    the heading “-Redeemable Warrants-Public Stockholders’ Warrants-Anti-Dilution Adjustments”).

 

We will not redeem the warrants as described above unless a registration
statement under the Securities Act covering the issuance of the Class A common stock issuable upon exercise of the warrants is then
effective and a current prospectus relating to those Class A common stock is available throughout the 30-day redemption period.
If and when the warrants become redeemable by us, we may exercise our redemption right even if we are unable to register or qualify the
underlying securities for sale under all applicable state securities laws.

 

We have established the last of the redemption criterion discussed
above to prevent a redemption call unless there is at the time of the call a significant premium to the warrant exercise price. If the
foregoing conditions are satisfied and we issue a notice of redemption of the warrants, each warrant holder will be entitled to exercise
his, her or its warrant prior to the scheduled redemption date. Any such exercise would not be done on a “cashless” basis
and would require the exercising warrant holder to pay the exercise price for each warrant being exercised. However, the price of the
Class A common stock may fall below the $18.00 redemption trigger price (as adjusted for adjustments to the number of shares issuable
upon exercise or the exercise price of a warrant as described under the heading “-Warrants-Public Stockholders’ Warrants-Anti-Dilution
Adjustments”) as well as the $11.50 (for whole shares) warrant exercise price after the redemption notice is issued.

 

Redemption
of warrants when the price per share of Class A common stock equals or exceeds $10.00. Once the warrants become exercisable,
we may redeem the outstanding warrants:

 

	 	•	in whole and not in part;

 

	 	•	at $0.10 per warrant upon a minimum of 30 days’
    prior written notice of redemption provided that holders will be able to exercise their warrants on a cashless basis prior to redemption
    and receive that number of shares determined by reference to the table below, based on the redemption date and the “fair market
    value” of our Class A common stock (as defined below in the immediately following paragraph) except as otherwise described
    below;

 

	 	•	if, and only if, the Reference Value (as defined above
    under the heading “-Redeemable Warrants-Public Stockholders’ Warrants-Redemption of warrants when the price per share
    of Class A common stock equals or exceeds $18.00”) equals or exceeds $10.00 per share (as adjusted for adjustments to
    the number of shares issuable upon exercise or the exercise price of a warrant as described under the heading “-Redeemable
    Warrants-Public Stockholders’ Warrants-Anti-Dilution Adjustments”); and

 

	 	•	if the Reference Value is less than $18.00 per share
    (as adjusted for adjustments to the number of shares issuable upon exercise or the exercise price of a warrant as described under
    the heading “ -Redeemable Warrants-Public Stockholders’ Warrants-Anti-dilution Adjustments”), the private placement
    warrants must also be concurrently called for redemption on the same terms as the outstanding public warrants, as described above.

 

Beginning on the date the notice of redemption is given until the
warrants are redeemed or exercised, holders may elect to exercise their warrants on a cashless basis. The numbers in the table below
represent the number of shares of Class A common stock that a warrant holder will receive upon such cashless exercise in connection
with a redemption by us pursuant to this redemption feature, based on the “fair market value” of our Class A common
stock on the corresponding redemption date (assuming holders elect to exercise their warrants and such warrants are not redeemed for
$0.10 per warrant), determined for these purposes based on the volume-weighted average price of our Class A common stock as reported
during the ten trading days immediately following the date on which the notice of redemption is sent to the holders of warrants, and
the number of months that the corresponding redemption date precedes the expiration date of the warrants, each as set forth in the table
below. We will provide our warrant holders with the final fair market value no later than one business day after the ten-trading day
period described above ends.

 

    

    

    

 

Pursuant to the warrant agreement, references above to Class A
common stock shall include a security other than Class A common stock into which the Class A common stock have been converted
or exchanged for in the event we are not the surviving company in our initial business combination. The numbers in the table below will
not be adjusted when determining the number of Class A common stock to be issued upon exercise of the warrants if we are not the
surviving entity following our initial business combination.

 

The share prices set forth in the column headings of the table below
will be adjusted as of any date on which the number of shares issuable upon exercise of a warrant or the exercise price of a warrant
is adjusted as set forth under the heading “-Anti-dilution Adjustments” below. If the number of shares issuable upon exercise
of a warrant is adjusted, the adjusted share prices in the column headings will equal the share prices immediately prior to such adjustment,
multiplied by a fraction, the numerator of which is the exercise price of the warrant after such adjustment and the denominator of which
is the price of the warrant immediately prior to such adjustment. In such an event, the number of shares in the table below shall be
adjusted by multiplying such share amounts by a fraction, the numerator of which is the number of shares deliverable upon exercise of
a warrant immediately prior to such adjustment and the denominator of which is the number of shares deliverable upon exercise of a warrant
as so adjusted. If the exercise price is adjusted, (a) in the case of an adjustment pursuant to the fifth paragraph under the heading
 “-Anti-dilution Adjustments” below, the adjusted share prices in the column headings will equal the unadjusted share price
multiplied by a fraction, the numerator of which is the higher of the Market Value and the Newly Issued Price as set forth under the
heading “ -Anti-dilution Adjustments” and the denominator of which is $10.00 and (b) in the case of an adjustment pursuant
to the second paragraph under the heading “- Anti-dilution Adjustments” below, the adjusted share prices in the column headings
will equal the unadjusted share price less the decrease in the exercise price of a warrant pursuant to such exercise price adjustment.

The exact fair market value and redemption date may not be set forth
in the table above, in which case, if the fair market value is between two values in the table or the redemption date is between two
redemption dates in the table, the number of shares of Class A common stock to be issued for each warrant exercised will be determined
by a straight-line interpolation between the number of shares set forth for the higher and lower fair market values and the earlier and
later redemption dates, as applicable, based on a 365 or 366-day year, as applicable. For example, if the volume weighted average price
of our Class A common stock as reported during the ten trading days immediately following the date on which the notice of redemption
is sent to the holders of warrants is $11.00 per share, and at such time there are 57 months until the expiration of the warrants, holders
may choose to, in connection with this redemption feature, exercise their warrants for 0.277 shares of Class A common stock for
each whole warrant. For an example where the exact fair market value and redemption date are not as set forth in the table above, if
the volume weighted average price of our Class A common stock as reported during the ten trading days immediately following the
date on which the notice of redemption is sent to the holders of warrants is $13.50 per share, and at such time there are 38 months until
the expiration of the warrants, holders may choose to, in connection with this redemption feature, exercise their warrants for 0.298
shares of Class A common stock for each whole warrant. In no event will the warrants be exercisable on a cashless basis in connection
with this redemption feature for more than 0.361 shares of Class A common stock per whole warrant (subject to adjustment). Finally,
as reflected in the table above, if the warrants are out of the money and about to expire, they cannot be exercised on a cashless basis
in connection with a redemption by us pursuant to this redemption feature, since they will not be exercisable for any Class A common
stock.

 

This redemption feature differs from the typical warrant redemption
features used in many other blank check offerings, which typically only provide for a redemption of warrants for cash (other than the
private placement warrants) when the trading price for the Class A common stock exceeds $18.00 per share for a specified period
of time. This redemption feature is structured to allow for all of the outstanding warrants to be redeemed when the Class A common
stock are trading at or above $10.00 per share, which may be at a time when the trading price of our Class A common stock is below
the exercise price of the warrants. We have established this redemption feature to provide us with the flexibility to redeem the warrants
without the warrants having to reach the $18.00 per share threshold set forth above under “-Redemption of warrants when the price
per share of Class A common stock equals or exceeds $18.00.” Holders choosing to exercise their warrants in connection with
a redemption pursuant to this feature will, in effect, receive a number of shares for their warrants based on an option pricing model
with a fixed volatility input as of November 16, 2020. This redemption right provides us with an additional mechanism by which to
redeem all of the outstanding warrants, and therefore have certainty as to our capital structure as the warrants would no longer be outstanding
and would have been exercised or redeemed. We will be required to pay the applicable redemption price to warrant holders if we choose
to exercise this redemption right and it will allow us to quickly proceed with a redemption of the warrants if we determine it is in
our best interest to do so. As such, we would redeem the warrants in this manner when we believe it is in our best interest to update
our capital structure to remove the warrants and pay the redemption price to the warrant holders.

 

    

    

    

 

As stated above, we can redeem the warrants when the shares of Class A
common stock are trading at a price starting at $10.00, which is below the exercise price of $11.50, because it will provide certainty
with respect to our capital structure and cash position while providing warrant holders with the opportunity to exercise their warrants
on a cashless basis for the applicable number of shares. If we choose to redeem the warrants when the shares of Class A common stock
are trading at a price below the exercise price of the warrants, this could result in the warrant holders receiving fewer shares of Class A
common stock than they would have received if they had chosen to wait to exercise their warrants for shares of Class A common stock
if and when such shares of Class A common stock were trading at a price higher than the exercise price of $11.50.

 

No fractional shares of Class A common stock will be issued upon
exercise. If, upon exercise, a holder would be entitled to receive a fractional interest in a share, we will round down to the nearest
whole number of the number of shares of Class A common stock to be issued to the holder. If, at the time of redemption, the warrants
are exercisable for a security other than Class A common stock pursuant to the warrant agreement (for instance, if we are not the
surviving company in our initial business combination), the warrants may be exercised for such security. At such time as the warrants
become exercisable for a security other than Class A common stock, the Company (or surviving company) will use its commercially
reasonable efforts to register under the Securities Act the security issuable upon the exercise of the warrants.

 

Redemption
Procedures. A holder of a warrant may notify us in writing in the event it elects to be subject to a requirement that such
holder will not have the right to exercise such warrant, to the extent that after giving effect to such exercise, such person (together
with such person’s affiliates), to the warrant agent’s actual knowledge, would beneficially own in excess of 4.9% or 9.8%
(or such other amount as a holder may specify) of the shares of Class A common stock outstanding immediately after giving effect
to such exercise.

 

Anti-dilution
Adjustments. If the number of outstanding shares of Class A common stock is increased by a stock dividend payable in
shares of Class A common stock, or by a split-up of shares of Class A common stock or other similar event, then, on the effective
date of such stock dividend, split-up or similar event, the number of shares of Class A common stock issuable on exercise of each
warrant will be increased in proportion to such increase in the outstanding shares of Class A common stock. A rights offering to
holders of Class A common stock entitling holders to purchase shares of Class A common stock at a price less than the historical
fair market value (as defined below) will be deemed a stock dividend of a number of shares of Class A common stock equal to the
product of (i) the number of shares of Class A common stock actually sold in such rights offering (or issuable under any other
equity securities sold in such rights offering that are convertible into or exercisable for Class A common stock) and (ii) one
minus the quotient of (x) the price per share of Class A common stock paid in such rights offering divided by (y) the
historical fair market value. For these purposes (i) if the rights offering is for securities convertible into or exercisable for
Class A common stock, in determining the price payable for Class A common stock, there will be taken into account any consideration
received for such rights, as well as any additional amount payable upon conversion or exercise and (ii) “historical fair market
value” means the volume weighted average price of Class A common stock as reported during the ten trading day period ending
on the trading day prior to the first date on which the shares of Class A common stock trade on the applicable exchange or in the
applicable market, regular way, without the right to receive such rights.

 

In addition, if we, at any time while the warrants are outstanding
and unexpired, pay a dividend or make a distribution in cash, securities or other assets to the holders of Class A common stock
on account of such shares of Class A common stock (or other shares of our capital stock into which the warrants are convertible),
other than (a) as described above, (b) certain ordinary cash dividends (initially defined as up to $0.50 per share in a 365
day period), (c) to satisfy the redemption rights of the holders of Class A common stock in connection with the completion
of our initial business combination, (d) to satisfy the redemption rights of the holders of Class A common stock in connection
with a stockholder vote to approve an amendment to our amended and restated certificate of incorporation (A) to modify the substance
or timing of our obligation to allow redemption in connection with our initial business combination or to redeem 100% of our public shares
if we do not complete our initial business combination within 24 months from the closing of our initial public offering or (B) with
respect to any other provision relating to stockholders’ rights or pre-initial business combination activity, or (e) in connection
with the redemption of our public shares upon our failure to complete our initial business combination, then the warrant exercise price
will be decreased, effective immediately after the effective date of such event, by the amount of cash and/or the fair market value of
any securities or other assets paid on each share of Class A common stock in respect of such event.

 

    

    

    

 

If the number of outstanding shares of our Class A common stock
is decreased by a consolidation, combination, reverse stock split or reclassification of shares of Class A common stock or other
similar event, then, on the effective date of such consolidation, combination, reverse stock split, reclassification or similar event,
the number of shares of Class A common stock issuable on exercise of each warrant will be decreased in proportion to such decrease
in outstanding shares of Class A common stock.

 

Whenever the number of shares of Class A common stock purchasable
upon the exercise of the warrants is adjusted, as described above, the warrant exercise price will be adjusted by multiplying the warrant
exercise price immediately prior to such adjustment by a fraction (x) the numerator of which will be the number of shares of Class A
common stock purchasable upon the exercise of the warrants immediately prior to such adjustment, and (y) the denominator of which
will be the number of shares of Class A common stock so purchasable immediately thereafter.

 

In addition, if (x) we issue additional shares of Class A
common stock or equity-linked securities for capital raising purposes in connection with the closing of our initial business combination
at a Newly Issued Price of less than $9.20 per share (with such issue price or effective issue price to be determined in good faith by
our board of directors and, in the case of any such issuance to our sponsor or its affiliates, without taking into account any founder
shares held by our sponsor or such affiliates, as applicable, prior to such issuance), (y) the aggregate gross proceeds from such
issuances represent more than 60% of the total equity proceeds, and interest thereon, available for the funding of our initial business
combination on the date of the consummation of our initial business combination (net of redemptions), and (z) the Market Value is
below $9.20 per share, the exercise price of the warrants will be adjusted (to the nearest cent) to be equal to 115% of the higher of
the Market Value and the Newly Issued Price, the $18.00 per share redemption trigger price described above under “-Redemption of
warrants when the price per share of Class A common stock equals or exceeds $18.00” and “-Redemption of warrants when
the price per share of Class A common stock equals or exceeds $10.00” will be adjusted (to the nearest cent) to be equal to
180% of the higher of the Market Value and the Newly Issued Price, and the $10.00 per share redemption trigger price described above
under “-Redemption of warrants when the price per share of Class A common stock equals or exceeds $10.00” will be adjusted
(to the nearest cent) to be equal to the higher of the Market Value and the Newly Issued Price.

 

In case of any reclassification or reorganization of the outstanding
shares of Class A common stock (other than those described above or that solely affects the par value of such shares of Class A
common stock), or in the case of any merger or consolidation of us with or into another corporation (other than a consolidation or merger
in which we are the continuing corporation and that does not result in any reclassification or reorganization of our outstanding shares
of Class A common stock), or in the case of any sale or conveyance to another corporation or entity of the assets or other property
of us as an entirety or substantially as an entirety in connection with which we are dissolved, the holders of the warrants will thereafter
have the right to purchase and receive, upon the basis and upon the terms and conditions specified in the warrants and in lieu of the
shares of our Class A common stock immediately theretofore purchasable and receivable upon the exercise of the rights represented
thereby, the kind and amount of shares of stock or other securities or property (including cash) receivable upon such reclassification,
reorganization, merger or consolidation, or upon a dissolution following any such sale or transfer, that the holder of the warrants would
have received if such holder had exercised their warrants immediately prior to such event. If less than 70% of the consideration receivable
by the holders of Class A common stock in such a transaction is payable in the form of Class A common stock in the successor
entity that is listed for trading on a national securities exchange or is quoted in an established over-the-counter market, or is to
be so listed for trading or quoted immediately following such event, and if the registered holder of the warrant properly exercises the
warrant within thirty days following public disclosure of such transaction, the warrant exercise price will be reduced as specified in
the warrant agreement based on the Black-Scholes value (as defined in the warrant agreement) of the warrant. The purpose of such exercise
price reduction is to provide additional value to holders of the warrants when an extraordinary transaction occurs during the exercise
period of the warrants pursuant to which the holders of the warrants otherwise do not receive the full potential value of the warrants
in order to determine and realize the option value component of the warrant. This formula is to compensate the warrant holder for the
loss of the option value portion of the warrant due to the requirement that the warrant holder exercise the warrant within 30 days of
the event. The Black-Scholes model is an accepted pricing model for estimating fair market value where no quoted market price for an
instrument is available.

 

    

    

    

 

The warrants are issued in registered form under the warrant agreement.
You should review a copy of the warrant agreement, which is incorporated by reference as an exhibit to the Annual Report on Form 10-K
of which this exhibit is a part, for a complete description of the terms and conditions applicable to the warrants. The warrant agreement
provides that the terms of the warrants may be amended without the consent of any holder to cure any ambiguity or correct any defective
provision, but requires the approval by the holders of at least 50% of the then outstanding public warrants to make any change that adversely
affects the interests of the registered holders of public warrants.

 

The warrants may be exercised upon surrender of the warrant certificate
on or prior to the expiration date at the offices of the warrant agent, with the exercise form on the reverse side of the warrant certificate
completed and executed as indicated, accompanied by full payment of the exercise price (or on a cashless basis, if applicable), by certified
or official bank check payable to us, for the number of warrants being exercised. The warrant holders do not have the rights or privileges
of holders of Class A common stock and any voting rights until they exercise their warrants and receive shares of Class A common
stock. After the issuance of shares of Class A common stock upon exercise of the warrants, each holder will be entitled to one (1) vote
for each share held of record on all matters to be voted on by stockholders.

 

No fractional shares will be issued upon exercise of the warrants.
If, upon exercise of the warrants, a holder would be entitled to receive a fractional interest in a share, we will, upon exercise, round
down to the nearest whole number of shares of Class A common stock to be issued to the warrant holder.

 

Private Placement Warrants

 

The private placement warrants (including the Class A common
stock issuable upon exercise of the private placement warrants) will not be transferable, assignable or salable until 30 days after the
completion of our initial business combination (except, among other limited exceptions, to our officers and directors and other persons
or entities affiliated with our sponsor) and they will not be redeemable by us (except as described above under “Description of
Securities-Redeemable Warrants-Public Stockholders’ Warrants-Redemption of warrants when the price per share of Class A common
stock equals or exceeds $10.00”) so long as they are held by our sponsor or its permitted transferees. Our sponsor, or its permitted
transferees, has the option to exercise the private placement warrants on a cashless basis. Except as described below, the private placement
warrants have terms and provisions that are identical to those of the warrants sold as part of the units in our initial public offering,
including as to exercise price, exercisability and exercise period. If the private placement warrants are held by holders other than
the sponsor or its permitted transferees, the private placement warrants will be redeemable by us and exercisable by the holders on the
same basis as the warrants included in the units sold in our initial public offering.

 

Except as described above under “-Public Stockholders’
Warrants-Redemption of warrants when the price per share of Class A common stock equals or exceeds $10.00,” if holders of
the private placement warrants elect to exercise them on a cashless basis, they would pay the exercise price by surrendering the warrants
for that number of shares of Class A common stock equal to the quotient obtained by dividing (x) the product of the number
of shares of Class A common stock underlying the warrants, multiplied by the excess of the “fair market value” of our
Class A common stock over the exercise price of the warrants by (y) the fair market value. The “fair market value”
shall mean the average last reported sale price of the Class A common stock for the ten trading days ending on the third trading
day prior to the date on which the notice of exercise is received by the warrant agent or on which the notice of redemption is sent to
the holders of warrants, as applicable. The reason that we have agreed that these warrants will be exercisable on a cashless basis so
long as they are held by the sponsor or its permitted transferees is because it is not known at this time whether they will be affiliated
with us following an initial business combination. If they remain affiliated with us, their ability to sell our securities in the open
market will be significantly limited. We expect to have policies in place that prohibit insiders from selling our securities except during
specific periods of time. Even during such periods of time when insiders will be permitted to sell our securities, an insider cannot
trade in our securities if he or she is in possession of material non-public information. Accordingly, unlike public stockholders who
could sell the shares of Class A common stock issuable upon exercise of the warrants freely in the open market, the insiders could
be significantly restricted from doing so. As a result, we believe that allowing the holders to exercise such warrants on a cashless
basis is appropriate.

 

    

    

    

 

In order to finance transaction costs in connection with an intended
initial business combination, our sponsor or an affiliate of our sponsor or certain of our officers and directors may, but are not obligated
to, loan us funds as may be required. Up to $1,500,000 of such loans may be converted into warrants at a price of $1.50 per warrant at
the option of the lender. Such warrants would be identical to the private placement warrants, including as to exercise price, exercisability
and exercise period. Except for the foregoing, the terms of such working capital loans by our sponsor or its affiliates, or our officers
and directors, if any, have not been determined and no written agreements exist with respect to such loans.

 

Our sponsor has agreed not to transfer, assign or sell any of the
private placement warrants (including the Class A common stock issuable upon exercise of any of these warrants) until the date that
is 30 days after the date we complete our initial business combination, except, among other limited exceptions, to our officers and directors
and other persons or entities affiliated with our sponsor.

 

Dividends

 

We have not paid any cash dividends on our common stock to date and
do not intend to pay cash dividends prior to the completion of an initial business combination. The payment of cash dividends in the
future will be dependent upon our revenues and earnings, if any, capital requirements and general financial conditions subsequent to
completion of an initial business combination. The payment of any cash dividends subsequent to an initial business combination will be
within the discretion of our board of directors at such time. If we incur any indebtedness, our ability to declare dividends may be limited
by restrictive covenants we may agree to in connection therewith.

 

Our Transfer Agent and Warrant Agent

 

The transfer agent for our common stock and warrant agent for our
warrants is Continental Stock Transfer & Trust Company. We have agreed to indemnify Continental Stock Transfer & Trust
Company in its roles as transfer agent and warrant agent, its agents and each of its stockholders, directors, officers and employees
against all claims and losses that may arise out of acts performed or omitted for its activities in that capacity, except for any liability
due to any gross negligence, willful misconduct or bad faith of the indemnified person or entity.

 

Our Amended and Restated Certificate of Incorporation

 

Our amended and restated certificate of incorporation contains certain
requirements and restrictions that will apply to us until the completion of our initial business combination. These provisions cannot
be amended without the approval of the holders of 65% of our common stock. Our initial stockholders will participate in any vote to amend
our amended and restated certificate of incorporation and will have the discretion to vote in any manner they choose. Specifically, our
amended and restated certificate of incorporation provides, among other things, that:

 

	 	•	If we do not complete our initial business combination
    within 24 months from the closing of our initial public offering or during any Extension Period, we will (i) cease all operations
    except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten business days thereafter
    subject to lawfully available funds therefor, redeem 100% of the public shares, at a per-share price, payable in cash, equal to the
    aggregate amount then on deposit in the trust account including interest earned on the funds held in the trust account and not previously
    released to us to pay our franchise and income taxes (less up to $100,000 of interest to pay dissolution expenses), divided by the
    number of then outstanding public shares, which redemption will completely extinguish public stockholders’ rights as stockholders
    (including the right to receive further liquidating distributions, if any), subject to applicable law, and (iii) as promptly
    as reasonably possible following such redemption, subject to the approval of our remaining stockholders and our board of directors,
    dissolve and liquidate, subject in each case to our obligations under Delaware law to provide for claims of creditors and the requirements
    of other applicable law;

 

    

    

    

 

	 	•	Prior to or in connection with our initial business
    combination, we may not issue additional shares of capital stock that would entitle the holders thereof to (i) receive funds
    from the trust account or (ii) vote on our initial business combination;

 

	 	•	Although we do not intend to enter into an initial
    business combination with a target business that is affiliated with our sponsor, directors or officers, we are not prohibited from
    doing so. In the event we enter into such a transaction, we, or a committee of independent directors, will obtain an opinion from
    an independent investment banking firm or an independent accounting firm that such an initial business combination is fair to our
    company from a financial point of view;

 

	 	•	If a stockholder vote on our initial business combination
    is not required by law and we do not decide to hold a stockholder vote for business or other reasons, we will offer to redeem our
    public shares pursuant to Rule 13e-4 and Regulation 14E of the Exchange Act, and will file tender offer documents with the SEC
    prior to completing our initial business combination which contain substantially the same financial and other information about our
    initial business combination and the redemption rights as is required under Regulation 14A of the Exchange Act; whether or not we
    maintain our registration under the our Exchange Act or our listing on the NYSE, we will provide our public stockholders with the
    opportunity to redeem their public shares by one of the two methods listed above;

 

	 	•	Our initial business combination will be approved by
    a majority of our independent directors;

 

	 	•	So long as we obtain and maintain a listing for our
    securities on the NYSE, the NYSE rules require that we must complete our initial business combination with one or more businesses
    that together have an aggregate fair market value of at least 80% of the net assets held in the trust account (excluding the deferred
    underwriting commissions and taxes payable) at the time of our signing a definitive agreement in connection with our initial business
    combination;

 

	 	•	If our stockholders approve an amendment to our amended
    and restated certificate of incorporation (i) to modify the substance or timing of our obligation to allow redemption in connection
    with our initial business combination or to redeem 100% of our public shares if we do not complete our initial business combination
    within 24 months from the closing of our initial public offering or (ii) with respect to any other provision relating to stockholders’
    rights or pre-business combination activity, we will provide our public stockholders with the opportunity to redeem all or a portion
    of their shares of Class A common stock upon such approval at a per-share price, payable in cash, equal to the aggregate amount
    then on deposit in the trust account, including interest earned on the funds held in the trust account and not previously released
    to us to pay our franchise and income taxes, divided by the number of then outstanding public shares; and

 

	 	•	We will not effectuate our initial business combination
    with another blank check company or a similar company with nominal operations.

 

In addition, our amended and restated certificate of incorporation
provides that under no circumstances will we redeem our public shares in an amount that would cause our net tangible assets to be less
than $5,000,001 upon consummation of our initial business combination and after payment of deferred underwriting commissions.

 

Certain Anti-Takeover Provisions of Delaware Law and our Amended
and Restated Certificate of Incorporation and Bylaws

 

We have opted out of Section 203 of the DGCL. However, our amended
and restated certificate of incorporation contains similar provisions providing that we may not engage in certain “business combinations”
with any “interested stockholder” for a three-year period following the time that the stockholder became an interested stockholder,
unless:

 

	 	•	prior to such time, our board of directors approved
    either the business combination or the transaction which resulted in the stockholder becoming an interested stockholder;

 

	 	•	upon consummation of the transaction that resulted
    in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of our voting stock outstanding
    at the time the transaction commenced, excluding certain shares; or

 

    

    

    

 

	 	•	at or subsequent to that time, the business combination
    is approved by our board of directors and by the affirmative vote of holders of at least 66-2/3% of the outstanding voting stock
    that is not owned by the interested stockholder.

 

Generally, a “business combination” includes a merger,
asset or stock sale or certain other transactions resulting in a financial benefit to the interested stockholder. Subject to certain
exceptions, an “interested stockholder” is a person who, together with that person’s affiliates and associates, owns,
or within the previous three years owned, 15% or more of our voting stock.

 

Under certain circumstances, this provision will make it more difficult
for a person who would be an “interested stockholder” to effect various business combinations with a corporation for a three-year
period. This provision may encourage companies interested in acquiring our company to negotiate in advance with our board of directors
because the stockholder approval requirement would be avoided if our board of directors approves either the business combination or the
transaction which results in the stockholder becoming an interested stockholder. These provisions also may have the effect of preventing
changes in our board of directors and may make it more difficult to accomplish transactions which stockholders may otherwise deem to
be in their best interests.

 

Our amended and restated certificate of incorporation provides that
the sponsor and its affiliates, any of its respective direct or indirect transferees who hold at least 15% of our outstanding common
stock after such transfer and any group as to which such persons are party to, do not constitute “interested stockholders”
for purposes of this provision.

 

Our amended and restated certificate of incorporation provides that
our board of directors is classified into three classes of directors. As a result, in most circumstances, a person can gain control of
our board only by successfully engaging in a proxy contest at two or more annual meetings.

 

Our authorized but unissued common stock and preferred stock are available
for future issuances without stockholder approval and could be utilized for a variety of corporate purposes, including future offerings
to raise additional capital, acquisitions and employee benefit plans. The existence of authorized but unissued and unreserved common
stock and preferred stock could render more difficult or discourage an attempt to obtain control of us by means of a proxy contest, tender
offer, merger or otherwise.

 

Exclusive forum for certain lawsuits

 

Our amended and restated certificate of incorporation requires, to
the fullest extent permitted by law, that derivative actions brought in our name, actions against directors, officers and employees for
breach of fiduciary duty and other similar actions may be brought only in the Court of Chancery in the State of Delaware, except any
action (A) as to which the Court of Chancery in the State of Delaware determines that there is an indispensable party not subject
to the jurisdiction of the Court of Chancery (and the indispensable party does not consent to the personal jurisdiction of the Court
of Chancery within ten days following such determination), (B) which is vested in the exclusive jurisdiction of a court or forum
other than the Court of Chancery, (C) for which the Court of Chancery does not have subject matter jurisdiction, or (D) any
action created by the Exchange Act or any other claim for which the federal courts have exclusive jurisdiction. If an action is brought
outside of Delaware, the stockholder bringing the suit will be deemed to have consented to service of process on such stockholder’s
counsel. Unless we consent in writing to the selection of an alternative forum, the federal district courts of the United States shall
be the exclusive forum for any action arising under the Securities Act. Although we believe this provision benefits us by providing increased
consistency in the application of Delaware law in the types of lawsuits to which it applies, a court may determine that this provision
is unenforceable, and to the extent it is enforceable, the provision may have the effect of discouraging lawsuits against our directors
and officers, although our stockholders will not be deemed to have waived our compliance with federal securities laws and the rules and
regulations thereunder.

 

    

    

    

 

Special meeting of stockholders

 

Our bylaws provide that special meetings of our
stockholders may be called only by a majority vote of our board of directors, by either our Chief Executive Officer or our Chairman.

 

Advance notice requirements for stockholder proposals and director
nominations

 

Our bylaws provide for advance notice procedures
with respect to stockholder proposals and the nomination of candidates for election as directors, other than nominations made by or at
the direction of our board of directors or a committee of our board of directors. In order for any matter to be “properly brought”
before a meeting, a stockholder will have to comply with advance notice requirements and provide us with certain information. Generally,
to be timely, a stockholder’s notice must be received at our principal executive offices not less than 90 days nor more than 120
days prior to the first anniversary date of the immediately preceding annual meeting of stockholders. Our bylaws also specify requirements
as to the form and content of a stockholder’s notice. Our bylaws allow the chairman of the meeting at a meeting of the stockholders
to adopt rules and regulations for the conduct of meetings, which may have the effect of precluding the conduct of certain business
at a meeting if the rules and regulations are not followed. These provisions may also defer, delay or discourage a potential acquirer
from conducting a solicitation of proxies to elect the acquirer’s own slate of directors or otherwise attempting to influence or
obtain control of us.

 

Action by written consent

 

Any action required or permitted to be taken by our common stockholders
must be effected by a duly called annual or special meeting of such stockholders and may not be effected by written consent of the stockholders
other than with respect to our Class B common stock.

 

Classified board of directors

 

Our board of directors is divided into three classes, Class I,
Class II and Class III, with members of each class serving staggered three-year terms. Our amended and restated certificate
of incorporation provides that the authorized number of directors may be changed only by resolution of the board of directors. Subject
to the terms of any preferred stock, any or all of the directors may be removed from office at any time, but only for cause and only
by the affirmative vote of holders of a majority of the voting power of all then outstanding shares of our capital stock entitled to
vote generally in the election of directors, voting together as a single class. Any vacancy on our board of directors, including a vacancy
resulting from an enlargement of our board of directors, may be filled only by vote of a majority of our directors then in office. However,
prior to our initial business combination, only holders of our founder shares will have the right to vote on the election of directors.
Holders of our public shares will not be entitled to vote on the election of directors during such time. In addition, prior to the completion
of an initial business combination, holders of a majority of our founder shares may remove a member of the board of directors for any
reason.

 

Class B common stock consent right

 

For so long as any shares of Class B common stock remain outstanding,
we may not, without the prior vote or written consent of the holders of a majority of the shares of Class B common stock then outstanding,
voting separately as a single class, amend, alter or repeal any provision of our amended and restated certificate of incorporation, whether
by merger, consolidation or otherwise, if such amendment, alteration or repeal would alter or change the powers, preferences or relative,
participating, optional or other or special rights of the Class B common stock. Any action required or permitted to be taken at
any meeting of the holders of Class B common stock may be taken without a meeting, without prior notice and without a vote, if a
consent or consents in writing, setting forth the action so taken, shall be signed by the holders of the outstanding Class B common
stock having not less than the minimum number of votes that would be necessary to authorize or take such action at a meeting at which
all shares of Class B common stock were present and voted.
