VOTING AGREEMENT

 

This Voting Agreement
(this “Agreement”) is made as of July 20, 2020 by and among (i) Tenzing Acquisition Corp.,
a British Virgin Islands corporation (together with its successors, including the Successor after the Conversion (as such terms
are defined in the Merger Agreement, defined below), the “Purchaser”), (ii) Reviva Pharmaceuticals,
Inc., a Delaware corporation (the “Company”), and (iii) the undersigned stockholder (“Holder”)
of the Company. Any capitalized term used but not defined in this Agreement will have the meaning ascribed to such term in the
Merger Agreement.

 

WHEREAS, on
or about the date hereof, the Purchaser, the Company, Tenzing Merger Subsidiary Inc., a Delaware corporation and a wholly-owned
subsidiary of the Purchaser (“Merger Sub”), and the other parties named therein, have entered into that
certain Agreement and Plan of Merger (as amended from time to time in accordance with the terms thereof, the “Merger
Agreement”), pursuant to which Merger Sub will merge with and into the Company, with the Company continuing as the
surviving entity (the “Merger”), and as a result of which, among other matters, all of the issued and
outstanding capital stock of the Company as of the Effective Time shall no longer be outstanding and shall automatically be cancelled
and shall cease to exist, in exchange for the right to receive Stockholder Merger Consideration as set forth in the Merger Agreement,
all upon the terms and subject to the conditions set forth in the Merger Agreement and in accordance with the applicable provisions
of the DGCL;

 

WHEREAS, the
Board of Directors of the Company has (a) approved and declared advisable the Merger Agreement, the Ancillary Documents, the Merger
and the other transactions contemplated by any such documents (collectively, the “Transactions”), (b)
determined that the Transactions are fair to and in the best interests of the Company and its stockholders (the “Company
Stockholders”) and (c) recommended the approval and the adoption by each of the Company Stockholders of the Merger
Agreement, the Ancillary Documents, the Merger and the other Transactions; and

 

WHEREAS, as
a condition to the willingness of the Purchaser to enter into the Merger Agreement, and as an inducement and in consideration
therefor, and in view of the valuable consideration to be received by Holder thereunder, and the expenses and efforts to be undertaken
by the Purchaser and the Company to consummate the Transactions, the Purchaser, the Company and Holder desire to enter into this
Agreement in order for Holder to provide certain assurances to the Purchaser regarding the manner in which Holder is bound hereunder
to vote any shares of capital stock of the Company which Holder beneficially owns, holds or otherwise has voting power (the “Shares”)
during the period from and including the date hereof through and including the date on which this Agreement is terminated in accordance
with its terms (the “Voting Period”) with respect to the Merger Agreement, the Merger, the Ancillary
Documents and the Transactions.

 

NOW, THEREFORE,
in consideration of the premises set forth above, which are incorporated in this Agreement as if fully set forth below, and intending
to be legally bound hereby, the parties hereby agree as follows:

 

    

    

    

 

1.                  
Covenant to Vote in Favor of Transactions. Holder agrees, with respect to all of the Shares:

 

(a)                  
during the Voting Period, at each meeting of the Company Stockholders or any class or series thereof, and in each written
consent or resolutions of any of the Company Stockholders in which Holder is entitled to vote or consent, Holder hereby unconditionally
and irrevocably agrees to participate in such meeting and vote (in person or by proxy), or consent to any action by written consent
or resolution with respect to, as applicable, the Shares (i) in favor of, and adopt, the Merger, the Merger Agreement, the Ancillary
Documents, any amendments to the Company’s Organizational Documents contemplated by the Merger Agreement, and all of the
other Transactions (and any actions required in furtherance thereof), (ii) in favor of the other
matters set forth in the Merger Agreement, and (iii) to vote the Shares in opposition to: (A) any Acquisition Proposal and any
and all other proposals (x) for the acquisition of the Company, (y) that could reasonably be expected to delay or impair the ability
of the Company to consummate the Merger, the Merger Agreement or any of the Transactions, or (z) which are in competition with
or materially inconsistent with the Merger Agreement or the Ancillary Documents; (B) other than as contemplated by the Merger
Agreement, any material change in (x) the present capitalization of the Company or any amendment of the Company’s Organizational
Documents or (y) the Company’s corporate structure or business; or (C) any other action or proposal involving any Target
Company that is intended, or would reasonably be expected, to prevent, impede, interfere with, delay, postpone or adversely affect
in any material respect the Transactions or would reasonably be expected to result in any of the conditions to the Closing under
the Merger Agreement not being fulfilled;

 

(b)                  
not to deposit, and to cause their Affiliates not to deposit, except as provided in this Agreement, any Shares owned by
Holder or his/her/its Affiliates in a voting trust or subject any Shares to any arrangement or agreement with respect to the voting
of such Shares, unless specifically requested to do so by the Company and the Purchaser in connection with the Merger Agreement,
the Ancillary Documents and any of the Transactions;

 

(c)                  
except as contemplated by the Merger Agreement or the Ancillary Documents, make, or in any manner participate in, directly
or indirectly, a “solicitation” of “proxies” or consents (as such terms are used in the rules of the SEC)
or powers of attorney or similar rights to vote, or seek to advise or influence any Person with respect to the voting of, any
shares of the Company capital stock in connection with any vote or other action with respect to the Transactions, other than to
recommend that stockholders of the Company vote in favor of adoption of the Merger Agreement and the Transactions and any other
proposal the approval of which is a condition to the obligations of the parties under the Merger Agreement (and any actions required
in furtherance thereof and otherwise as expressly provided by Section 1 of this Agreement); and

 

(d)                  
to refrain from exercising any dissenters’ rights or rights of appraisal under applicable law at any time with respect
to the Merger, the Merger Agreement, the Ancillary Documents and any of the Transactions, including pursuant to the DGCL.

 

2.                  
 Grant of Proxy. Holder, with respect to all of the Shares, hereby irrevocably grants to, and appoints, the Purchaser
and any designee of the Purchaser (determined in the Purchaser’s sole discretion) as Holder’s attorney-in-fact and
proxy, with full power of substitution and resubstitution, for and in Holder’s name, to vote, or cause to be voted (including
by proxy or written consent, if applicable) any Shares owned (whether beneficially or of record) by Holder. The proxy granted
by Holder pursuant to this Section 2 is irrevocable and is granted in consideration of the Purchaser entering into this
Agreement and the Merger Agreement and incurring certain related fees and expenses. Holder hereby affirms that such irrevocable
proxy is coupled with an interest by reason of the Merger Agreement and, except upon the termination of this Agreement in accordance
with Section 5(a), is intended to be irrevocable. Holder agrees, until this Agreement is terminated in accordance with
Section 5(a), to vote its Shares in accordance with Section 1 above.

3.                  
Other Covenants. 

 

(a)               
No Transfers. Holder agrees that during the Voting Period it shall not, and shall cause its Affiliates not to, without
the Purchaser’s prior written consent, (A) offer for sale, sell (including short sales), transfer, tender, pledge, encumber,
assign or otherwise dispose of (including by gift) (collectively, a “Transfer”), or enter into any contract,
option, derivative, hedging or other agreement or arrangement or understanding (including any profit-sharing arrangement) with
respect to, or consent to, a Transfer of, any or all of the Shares; (B) grant any proxies or powers of attorney with respect to
any or all of the Shares; (C) permit to exist any lien of any nature whatsoever (other than those imposed by this Agreement, applicable
securities Laws or the Company’s Organizational Documents, as in effect on the date hereof) with respect to any or all of
the Shares; or (D) take any action that would have the effect of preventing, impeding, interfering with or adversely affecting
Holder’s ability to perform its obligations under this Agreement. The Company hereby agrees that it shall not permit any
Transfer of the Shares in violation of this Agreement. Holder agrees with, and covenants to, the Purchaser that Holder shall not
request that the Company register the Transfer (book-entry or otherwise) of any certificate or uncertificated interest representing
any Shares during the term of this Agreement without the prior written consent of the Purchaser, and the Company hereby agrees
that it shall not effect any such Transfer.

 

(b)               
Permitted Transfers. Section 3(a) shall not prohibit a Transfer of Shares by Holder (i) to any family member
or trust for the benefit of any family member, (ii) to any stockholder, member or partner of Holder, if an entity, (iii) to any
Affiliate of Holder, or (iv) to any person or entity if and to the extent required by any non-consensual Order, by divorce decree
or by will, intestacy or other similar Applicable Law, so long as, in the case of the foregoing clauses (i), (ii) and (iii), the
assignee or transferee agrees to be bound by the terms of this Agreement and executes and delivers to the parties hereto a written
consent and joinder memorializing such agreement. During the term of this Agreement, the Company will not register or otherwise
recognize the transfer (book-entry or otherwise) of any Shares or any certificate or uncertificated interest representing any
of Holder’s Shares, except as permitted by, and in accordance with, this Section 3(b).

 

(c)                  
Changes to Shares. In the event of a stock dividend or distribution, or any change in the shares of capital stock
of the Company by reason of any stock dividend or distribution, stock split, recapitalization, combination, conversion, exchange
of shares or the like, the term “Shares” shall be deemed to refer to and include the Shares as well as all such stock
dividends and distributions and any securities into which or for which any or all of the Shares may be changed or exchanged or
which are received in such transaction. Holder agrees during the Voting Period to notify the Purchaser and the Company promptly
in writing of the number and type of any additional Shares acquired by Holder, if any, after the date hereof.

 

(d)                  
Compliance with Merger Agreement. Holder agrees to not during the Voting Period take or agree or commit to take
any action that would make any representation and warranty of Holder contained in this Agreement inaccurate in any material respect.
Holder further agrees that it shall use its commercially reasonable efforts to cooperate with the Purchaser to effect the Merger,
the other Transactions, the Merger Agreement, the Ancillary Documents and the provisions of this Agreement.

 

(e)                  
Registration Statement. During the Voting Period, Holder agrees to provide to the Purchaser, the Company and their

or their respective Representatives for inclusion in the Registration Statement.

 

    3

    

    

 

(f)                   
Publicity. Holder shall not issue any press release or otherwise make any public statements with respect to the
Transactions or the transactions contemplated herein without the prior written approval of the Company and the Purchaser. Holder
hereby authorizes the Company and the Purchaser to publish and disclose in any announcement or disclosure required by the SEC,
Nasdaq or the Registration Statement (including all documents and schedules filed with the SEC in connection with the foregoing),
Holder’s identity and ownership of the Shares and the nature of Holder’s commitments and agreements under this Agreement,
the Merger Agreement and any other Ancillary Documents.

 

(g)                 
 No Inconsistent Agreements. Holder hereby covenants and agrees that, except for this
Agreement, Holder (i) has not entered into, nor will enter into at any time while this Agreement remains in effect, any voting
agreement or voting trust with respect to the Shares inconsistent with Holder’s obligations pursuant to this Agreement,
(ii) has not granted, nor will grant at any time while this Agreement remains in effect, a proxy, a consent or power of attorney
with respect to the Shares and (iii) has not entered into any agreement or knowingly taken any action (nor will enter into any
agreement or knowingly take any action) that would make any representation or warranty of Holder contained herein untrue or incorrect
in any material respect or have the effect of preventing Holder from performing any of its material obligations under this Agreement.

 

4.                  
Representations and Warranties of Holder. Holder hereby represents and warrants to the Purchaser and the Company
that: (i) Holder is the beneficial owner of the Shares set forth under Holder’s name on the signature page hereto, which,
at the date of this Agreement and at all times up until the earlier to occur of (x) the Effective Time and (y) the date of termination
of this Agreement, (A) will be free and clear of all Liens of any nature whatsoever (other than those imposed by this Agreement,
applicable securities Laws or the Company’s Organizational Documents), and (B) Holder has and will have sole power to vote
or cause to be voted such Shares; (ii) as of the date hereof, Holder does not own of record or beneficially any shares of outstanding
capital stock of the Company other than the Shares set forth under Holder’s name on the signature page hereto (excluding
shares as to which Holder currently disclaims beneficial ownership in accordance with applicable Law); (iii) Holder has the legal
capacity, power and authority to enter into and perform all of Holder’s obligations under this Agreement; (iv) this Agreement
has been duly and validly executed and delivered by Holder and constitutes a valid and binding agreement of Holder, enforceable
against Holder in accordance with its terms, subject to (x) laws of general application relating to bankruptcy, insolvency and
the relief of debtors and (y) rules of law governing specific performance, injunctive relief and other equitable remedies; and
(v) none of the execution and delivery of this Agreement by Holder, the performance of its obligations hereunder or the consummation
by it of the transactions contemplated hereby shall (A) result in, or give rise to, a violation or breach of or a default under
any of the terms of any Contract or obligation to which Holder is a party or by which Holder or any of the Shares may be bound,
or (B) violate any applicable Law or Order, except in each case of clauses (A) and (B) as would not reasonably be expected to
impair Holder’s ability to perform its obligations under this Agreement in any material respect.

 

5.                  
Miscellaneous.

 

(a)                  
Termination. Notwithstanding anything to the contrary contained herein, this Agreement shall automatically terminate,
and none of the Purchaser, the Company or Holder shall have any rights or obligations hereunder, upon the earliest to occur of
(i) the mutual written consent of the Purchaser, the Company and Holder, (ii) the Effective Time (following the performance of
the obligations of the parties hereunder required to be performed at or prior to the Effective Time), and (iii) the date of termination
of the Merger Agreement in accordance with its terms. The termination of this Agreement shall not prevent any party hereunder
from seeking any remedies (at law or in equity) against another party hereto or relieve such party from liability for such party’s
breach of any terms of this Agreement. Notwithstanding anything to the contrary herein, the provisions of this Section 5(a)
shall survive the termination of this Agreement. 

 

(b)               
Fiduciary Duties. Notwithstanding anything in this Agreement to the contrary: (i) Holder makes no agreement or understanding
herein in any capacity other than solely in Holder’s capacity as a beneficial owner of the Shares; and (ii) nothing in this
Agreement shall be construed to limit or affect Holder, or any Affiliate or designee of Holder, in any other capacity (including
as an officer of the Company or as a member of the Company’s board of directors in acting in his or her capacity as an officer
or director of the Company) or in exercising his or her fiduciary duties and responsibilities as an officer of the Company or
as a member of the Company’s board of directors.

(c)                  
 Binding Effect; Assignment. This Agreement and all of the provisions hereof shall be binding upon and inure to the
benefit of the parties hereto and their respective permitted successors and assigns. This Agreement and all obligations of Holder
are personal to Holder and may not be assigned, transferred or delegated by Holder at any time without the prior written consent
of the Purchaser and the Company, and any purported assignment, transfer or delegation without such consent shall be null and
void ab initio. Each of the Company and the Purchaser may freely assign any or all of its rights under this Agreement, in whole
or in part, to any successor entity (whether by merger, consolidation, equity sale, asset sale or otherwise) without obtaining
the consent or approval of Holder.

 

(d)                  
Third Parties. Nothing contained in this Agreement or in any instrument or document executed by any party in connection
with the transactions contemplated hereby shall create any rights in, or be deemed to have been executed for the benefit of, any
person that is not a party hereto or thereto or a successor or permitted assign of such a party.

 

(e)

principles thereof. All Actions arising out of or relating to this Agreement shall be heard and determined exclusively in any
state or federal court located in New York, New York (or in any appellate courts thereof) (the “Specified Courts”).
Each party hereto hereby (i) submits to the exclusive jurisdiction of any Specified Court for the purpose of any Action arising
out of or relating to this Agreement brought by any party hereto and (ii) irrevocably waives, and agrees not to assert by
way of motion, defense or otherwise, in any such Action, any claim that it is not subject personally to the jurisdiction of the
above-named courts, that its property is exempt or immune from attachment or execution, that the Action is brought in an inconvenient
forum, that the venue of the Action is improper, or that this Agreement or the transactions contemplated hereby may not be enforced
in or by any Specified Court. Each party agrees that a final judgment in any Action shall be conclusive and may be enforced in
other jurisdictions by suit on the judgment or in any other manner provided by Law. Each party irrevocably consents to the service

by this Agreement, on behalf of itself, or its property, by personal delivery of copies of such process to such party at the applicable
address set forth or referred to in Section 5(g). Nothing in this Section 5(d) shall affect the right
of any party to serve legal process in any other manner permitted by applicable law.

 

(f)                   
WAIVER OF JURY TRIAL. EACH OF THE PARTIES HERETO HEREBY WAIVES TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW

Amendments and Waivers. Any term of this Agreement may be amended and the observance of any term of this Agreement
may be waived (either generally or in a particular instance, and either retroactively or prospectively) only with the written
consent of the Purchaser, the Company and the Holder. No failure or delay by a party in exercising any right hereunder shall operate

    6

    

    

 

(j)                   
 Severability. In case any provision in this Agreement shall be held invalid, illegal or unenforceable in a jurisdiction,
such provision shall be modified or deleted, as to the jurisdiction involved, only to the extent necessary to render the same
valid, legal and enforceable, and the validity, legality and enforceability of the remaining provisions hereof shall not in any
way be affected or impaired thereby nor shall the validity, legality or enforceability of such provision be affected thereby in
any other jurisdiction. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced,
the parties will substitute for any invalid, illegal or unenforceable provision a suitable and equitable provision that carries
out, so far as may be valid, legal and enforceable, the intent and purpose of such invalid, illegal or unenforceable provision.

 

(k)                  
Specific Performance. Holder acknowledges that its obligations under this Agreement are unique, recognizes and affirms
that in the event of a breach of this Agreement by Holder, money damages will be inadequate and the Company and the Purchaser
will have not adequate remedy at law, and agree that irreparable damage would occur in the event that any of the provisions of
this Agreement were not performed by Holder in accordance with their specific terms or were otherwise breached. Accordingly, the
Company and the Purchaser shall be entitled to an injunction or restraining order to prevent breaches of this Agreement by Holder
and to enforce specifically the terms and provisions hereof, without the requirement to post any bond or other security or to
prove that money damages would be inadequate, this being in addition to any other right or remedy to which such party may be entitled
under this Agreement, at law or in equity.

 

(l)                
Expenses. Each party shall be responsible for its own fees and expenses (including the fees and expenses of investment
bankers, accountants and counsel) in connection with the entering into of this Agreement, the performance of its obligations hereunder
and the consummation of the transactions contemplated hereby; provided, that in the event of any Action arising out of or relating
to this Agreement, the non-prevailing party in any such Action will pay its own expenses and the reasonable documented out-of-pocket
expenses, including reasonable attorneys’ fees and costs, reasonably incurred by the prevailing party.

 

(m)             
No Partnership, Agency or Joint Venture. This Agreement is intended to create a contractual relationship among Holder,
the Company and the Purchaser, and is not intended to create, and does not create, any agency, partnership, joint venture or any
like relationship among the parties hereto or among any other Company shareholders entering into voting agreements with the Company
or the Purchaser. Holder is not affiliated with any other holder of securities of the Company entering into a voting agreement
with the Company or the Purchaser in connection with the Merger Agreement and has acted independently regarding its decision to
enter into this Agreement. Nothing contained in this Agreement shall be deemed to vest in the Company or the Purchaser any direct
or indirect ownership or incidence of ownership of or with respect to any Shares.

 

(n)                  
Further Assurances. From time to time, at another party’s request and without further consideration, each
party shall execute and deliver such additional documents and take all such further action as may be reasonably necessary or desirable
to consummate the transactions contemplated by this Agreement.

 

    7

    

    

 

(o)                  
Entire Agreement. This Agreement (together with the Merger Agreement to the extent referred to herein) constitutes
the full and entire understanding and agreement among the parties with respect to the subject matter hereof, and any other written
or oral agreement relating to the subject matter hereof existing between the parties is expressly canceled; provided,
that, for the avoidance of doubt, the foregoing shall not affect the rights and obligations of the parties under the Merger Agreement
or any Ancillary Document. Notwithstanding the foregoing, nothing in this Agreement shall limit any of the rights or remedies
of the Purchaser or any of the obligations of Holder under any other agreement between Holder and the Purchaser or any certificate
or instrument executed by Holder in favor of the Purchaser, and nothing in any other agreement, certificate or instrument shall
limit any of the rights or remedies of the Purchaser or any of the obligations of Holder under this Agreement.

 

(p)                  
Counterparts; Facsimile. This Agreement may also be executed and delivered by facsimile or electronic signature
or by email in portable document format in two or more counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

THIS LOCK-UP AGREEMENT

Corp. a British Virgin Islands corporation, which will be known after the consummation of the transactions contemplated by
the Merger Agreement (as defined below) as “Reviva Pharmaceuticals Holdings, Inc.” (including any successor entity
thereto, including the Successor after the Conversion (as such terms are defined in the Merger Agreement), the “Purchaser”),
(ii) Tenzing LLC, in the capacity under the Merger Agreement as the Purchaser Representative (including any successor Purchaser
Representative appointed in accordance therewith, the “Purchaser Representative”), and (iii) the undersigned
(“Holder”). Any capitalized term used but not defined in this Agreement will have the meaning ascribed
to such term in the Merger Agreement.

 

WHEREAS, on
or about the date hereof, (i) the Purchaser, (ii) Tenzing Merger Subsidiary Inc., a Delaware corporation and a wholly-owned subsidiary
of the Purchaser (“Merger Sub”), (iii) the Purchaser Representative, (iv) Laxminarayan Bhat in the capacity
as the Seller Representative under the Merger Agreement, and (v) Reviva Pharmaceuticals, Inc., a Delaware corporation (the “Company”),
entered into that certain Agreement and Plan of Merger (as amended from time to time in accordance with the terms thereof, the
“Merger Agreement”), pursuant to which Merger Sub will merge with and into the Company, with the Company
continuing as the surviving entity (the “Merger”), and as a result of which, (a) all of the issued and
outstanding capital stock of the Company, immediately prior to the consummation of the Merger (the “Closing”),
shall no longer be outstanding and shall automatically be cancelled and shall cease to exist, in exchange for the right to receive
Stockholder Merger Consideration, subject to the withholding of the Escrow Shares being deposited in the Escrow Account in accordance
with the terms and conditions of the Merger Agreement and the Escrow Agreement and (b) the Company Options and Company Warrants
shall be assumed by Purchaser with the result that such assumed Company Options and Company Warrants shall be replaced with Assumed
Options and Assumed Warrants, respectively, exercisable into shares of Purchaser Common Stock (as equitably adjusted), all upon
the terms and subject to the conditions set forth in the Merger Agreement and in accordance with the applicable provisions of
the of the DGCL;

 

WHEREAS, as
of the date hereof, Holder is a holder of the Company Stock, Company Options and/or Company Warrants in such amounts as set forth
underneath Holder’s name on the signature page hereto; and

 

WHEREAS, pursuant
to the Merger Agreement, and in view of the valuable consideration to be received by Holder thereunder, the parties desire to
enter into this Agreement, pursuant to which the Stockholder Merger Consideration, the Assumed Options and/or the Assumed Warrants
and all Purchaser Common Stock underlying the Assumed Options and the Assumed Warrants, received by Holder in the Merger in exchange
for the Company Stock, Company Options, and/or Company Warrants set forth underneath Holder’s name on the signature page
hereto, including its right to any Escrow Shares and any Earnout Shares that may be issued after the Closing with respect to the
Company Stock, Company Options, and/or Company Warrants set forth underneath Holder’s name on the signature page hereto
in accordance with the Merger Agreement (all such securities, together with any securities paid as dividends or distributions
with respect to such securities or into which such securities are exchanged or converted, the “Restricted Securities”)
shall become subject to limitations on disposition as set forth herein.

 

 NOW, THEREFORE,
in consideration of the premises set forth above, which are incorporated in this Agreement as if fully set forth below, and intending
to be legally bound hereby, the parties hereby agree as follows:

 

    
    1 

     

    

 

1.            
Lock-Up Provisions.

 

(a)               
Holder hereby agrees not to, during the period (the “Lock-Up Period”) commencing from the Closing
and ending on the earlier of (x) the one (1) year anniversary of the date of the Closing, (y) the date on which the closing price
of the Purchaser Common Stock equals or exceeds $12.00 per share (as adjusted for stock splits, stock dividends, reorganizations,
recapitalizations and the like) for any twenty (20) trading days within any thirty (30) trading day period commencing at least
one-hundred fifty (150) days after the Closing, and (z) the date after the Closing on which Purchaser consummates a liquidation,
merger, share exchange or other similar transaction with an unaffiliated third party that results in all of Purchaser’s
stockholders having the right to exchange their equity holdings in Purchaser for cash, securities or other property: (i) lend,
offer, pledge, hypothecate, encumber, donate, assign, sell, contract to sell, sell any option or contract to purchase, purchase
any option or contract to sell, grant any option, right or warrant to purchase, or otherwise transfer or dispose of, directly
or indirectly, any Restricted Securities, (ii) enter into any swap or other arrangement that transfers to another, in whole
or in part, any of the economic consequences of ownership of the Restricted Securities, or (iii) publicly disclose the intention
to do any of the foregoing, whether any such transaction described in clauses (i), (ii) or (iii) above is to be settled by delivery
of Restricted Securities or other securities, in cash or otherwise (any of the foregoing described in clauses (i), (ii) or (iii),
a “Prohibited Transfer”). The foregoing sentence shall not apply to the transfer of any or all of the
Restricted Securities owned by Holder (other than any Escrow Shares until such Escrow Shares are disbursed to Holder from the
Escrow Account in accordance with the terms and conditions of the Merger Agreement and the Escrow Agreement) (I) by gift, will
or intestate succession upon the death of Holder, (II) to any Permitted Transferee (as defined below) or (III) pursuant to a court
order or settlement agreement related to the distribution of assets in connection with the dissolution of marriage or civil union;
provided, however, that in any of cases (I), (II) or (III) it shall be a condition to such transfer that the transferee executes
and delivers to the Purchaser and the Purchaser Representative an agreement stating that the transferee is receiving and holding
the Restricted Securities subject to the provisions of this Agreement applicable to Holder, and there shall be no further transfer
of such Restricted Securities except in accordance with this Agreement. As used in this Agreement, the term “Permitted
Transferee” shall mean: (A) the members of Holder’s immediate family (for purposes of this Agreement, “immediate
family” shall mean with respect to any natural person, any of the following: such person’s spouse, the siblings of
such person and his or her spouse, and the direct descendants and ascendants (including adopted and step children and parents)
of such person and his or her spouses and siblings), (B) any trust for the direct or indirect benefit of Holder or the immediate
family of Holder, (C) if Holder is a trust, the trustor or beneficiary of such trust or to the estate of a beneficiary of such
trust, (D) if Holder is an entity, as a distribution to limited partners, shareholders, members of, or owners of similar equity
interests in Holder upon the liquidation and dissolution of Holder, and (E) any affiliate of Holder. Holder further agrees to
execute such agreements as may be reasonably requested by Purchaser or the Purchaser Representative that are consistent with the
foregoing or that are necessary to give further effect thereto.

 

(b)               
Holder further acknowledges and agrees that it shall not be permitted to engage in any Prohibited Transfer with respect
to any Escrow Shares until both the Lock-Up Period has expired and such Escrow Shares have been disbursed to Holder from the Escrow
Account in accordance with the terms and conditions of the Merger Agreement and the Escrow Agreement.

 

(c)               
If any Prohibited Transfer is made or attempted contrary to the provisions of this Agreement, such purported Prohibited
Transfer shall be null and void ab initio, and Purchaser shall refuse to recognize any such purported transferee of the Restricted
Securities as one of its equity holders for any purpose. In order to enforce this Section 1, Purchaser may impose
stop-transfer instructions with respect to the Restricted Securities of Holder (and Permitted Transferees and assigns thereof)
until the end of the Lock-Up Period.

 

    2 

     

    

 

(d)               
 During the Lock-Up Period (and with respect to any Escrow Shares, if longer, during the period when such Escrow Shares
are held in the Escrow Account), each certificate evidencing any Restricted Securities shall be stamped or otherwise imprinted
with a legend in substantially the following form, in addition to any other applicable legends:

 

“THE SECURITIES REPRESENTED
BY THIS CERTIFICATE ARE SUBJECT TO RESTRICTIONS ON TRANSFER SET FORTH IN A LOCK-UP AGREEMENT, DATED AS OF [●], 2020, BY
AND AMONG THE ISSUER OF SUCH SECURITIES (THE “ISSUER”), A CERTAIN REPRESENTATIVE OF THE ISSUER NAMED THEREIN AND THE
ISSUER’S SECURITY HOLDER NAMED THEREIN, AS AMENDED. A COPY OF SUCH LOCK-UP AGREEMENT WILL BE FURNISHED WITHOUT CHARGE BY
THE ISSUER TO THE HOLDER HEREOF UPON WRITTEN REQUEST.”

 

(e)               
For the avoidance of any doubt, Holder shall retain all of its rights as a stockholder of the Purchaser during the Lock-Up
Period, including the right to vote any Restricted Securities, subject to the terms of the Merger Agreement and the Escrow Agreement
with respect to Escrow Shares.

 

(f)                
Promptly upon the expiration of the Lock-up Period (and with respect to any Escrow Shares, if released to Holder after
the expiration of the Lock-Up Period, promptly upon release from the Escrow Account), the Purchaser agrees to take all commercially
reasonable steps necessary to promptly effect the removal of the legend described in Section 1(d) above, and reissue to
Holder, at the Purchaser’s sole expense, a new certificate without the legend.

 

2.            
Miscellaneous.

 

(a)               
Termination of Merger Agreement. This Agreement shall be binding upon Holder upon Holder’s execution and delivery
of this Agreement, but this Agreement shall only become effective upon the Closing. Notwithstanding anything to the contrary contained
herein, in the event that the Merger Agreement is terminated in accordance with its terms prior to the Closing, this Agreement
and all rights and obligations of the parties hereunder shall automatically terminate and be of no further force or effect.

 

(b)               
Binding Effect; Assignment. This Agreement and all of the provisions hereof shall be binding upon and inure to the
benefit of the parties hereto and their respective permitted successors and assigns. This Agreement and all obligations of Holder
are personal to Holder and may not be transferred or delegated by Holder at any time. The Purchaser may freely assign any or all
of its rights under this Agreement, in whole or in part, to any successor entity (whether by merger, consolidation, equity sale,
asset sale or otherwise) without obtaining the consent or approval of Holder. If the Purchaser Representative is replaced in accordance
with the terms of the Merger Agreement, the replacement Purchaser Representative shall automatically become a party to this Agreement
as if it were the original Purchaser Representative hereunder.

 

(c)               
Third Parties. Nothing contained in this Agreement or in any instrument or document executed by any party in connection
with the transactions contemplated hereby shall create any rights in, or be deemed to have been executed for the benefit of, any
person or entity that is not a party hereto or thereto or a successor or permitted assign of such a party.

 

    3 

     

    

 

(d)               
Governing Law; Jurisdiction. This Agreement and any dispute or controversy arising out of or relating to this Agreement
shall be governed by and construed in accordance with the laws of the State of New York, without regard to the conflict of law
principles thereof. All Actions arising out of or relating to this Agreement shall be heard and determined exclusively in any
state or federal court located in New York, New York (or in any appellate courts thereof) (the “Specified Courts”).
Each party hereto hereby (i) submits to the exclusive jurisdiction of any Specified Court for the purpose of any Action arising
out of or relating to this Agreement brought by any party hereto and (ii) irrevocably waives, and agrees not to assert by
way of motion, defense or otherwise, in any such Action, any claim that it is not subject personally to the jurisdiction of the
above-named courts, that its property is exempt or immune from attachment or execution, that the Action is brought in an inconvenient
forum, that the venue of the Action is improper, or that this Agreement or the transactions contemplated hereby may not be enforced
in or by any Specified Court. Each party agrees that a final judgment in any Action shall be conclusive and may be enforced in
other jurisdictions by suit on the judgment or in any other manner provided by Law. Each party irrevocably consents to the service
of the summons and complaint and any other process in any other action or proceeding relating to the transactions contemplated
by this Agreement, on behalf of itself, or its property, by personal delivery of copies of such process to such party at the applicable
address set forth in Section 2(g).
Nothing in this Section 2(d) shall affect the right of any party to serve legal process in any other manner permitted
by applicable law.

 

(e)               
WAIVER OF JURY TRIAL. EACH OF THE PARTIES HERETO HEREBY WAIVES TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW
ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY WITH RESPECT TO ANY ACTION DIRECTLY OR INDIRECTLY ARISING OUT OF, UNDER OR IN CONNECTION
WITH THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY. EACH PARTY HERETO (i) CERTIFIES THAT NO REPRESENTATIVE OF ANY OTHER
PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF ANY ACTION, SEEK TO ENFORCE THAT
FOREGOING WAIVER AND (ii) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY,
AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 2(e).

(h)               
Amendments and Waivers. Any term of this Agreement may be amended and the observance of any term of this Agreement
may be waived (either generally or in a particular instance, and either retroactively or prospectively) only with the written
consent of the Purchaser, the Purchaser Representative and Holder. No failure or delay by a party in exercising any right hereunder
shall operate as a waiver thereof. No waivers of or exceptions to any term, condition, or provision of this Agreement, in any
one or more instances, shall be deemed to be or construed as a further or continuing waiver of any such term, condition, or provision.

 

    5 

     

    

 

(i)                
Severability. In case any provision in this Agreement shall be held invalid, illegal or unenforceable in a jurisdiction,
such provision shall be modified or deleted, as to the jurisdiction involved, only to the extent necessary to render the same
valid, legal and enforceable, and the validity, legality and enforceability of the remaining provisions hereof shall not in any
way be affected or impaired thereby nor shall the validity, legality or enforceability of such provision be affected thereby in
any other jurisdiction. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced,
the parties will substitute for any invalid, illegal or unenforceable provision a suitable and equitable provision that carries
out, so far as may be valid, legal and enforceable, the intent and purpose of such invalid, illegal or unenforceable provision.

 

(j)                
Specific Performance. Each party acknowledges that its obligations under this Agreement are unique, recognizes and
affirms that in the event of a breach of this Agreement by such party, money damages will be inadequate and the other parties
will have no adequate remedy at law, and agrees that irreparable damage would occur in the event that any of the provisions of
this Agreement were not performed by such party in accordance with their specific terms or were otherwise breached. Accordingly,
each party shall be entitled to an injunction or restraining order to prevent breaches of this Agreement by the other parties
and to enforce specifically the terms and provisions hereof, without the requirement to post any bond or other security or to
prove that money damages would be inadequate, this being in addition to any other right or remedy to which such party may be entitled
under this Agreement, at law or in equity.

 

(k)               
Entire Agreement. This Agreement constitutes the full and entire understanding and agreement among the parties with
respect to the subject matter hereof, and any other written or oral agreement relating to the subject matter hereof existing between
the parties is expressly canceled; provided, that, for the avoidance of doubt, the foregoing shall not affect the
rights and obligations of the parties under the Merger Agreement or any Ancillary Document. Notwithstanding the foregoing, nothing
in this Agreement shall limit any of the rights or remedies of the Purchaser and the Purchaser Representative or any of the obligations
of Holder under any other agreement between Holder and the Purchaser or the Purchaser Representative or any certificate or instrument
executed by Holder in favor of the Purchaser or the Purchaser Representative, and nothing in any other agreement, certificate
or instrument shall limit any of the rights or remedies of the Purchaser or the Purchaser Representative or any of the obligations
of Holder under this Agreement.

 

(l)                
Further Assurances. From time to time, at another party’s request and without further consideration (but at
the requesting party’s reasonable cost and expense), each party shall execute and deliver such additional documents and
take all such further action as may be reasonably necessary to consummate the transactions contemplated by this Agreement.

 

(m)             
Counterparts; Facsimile.  This Agreement may also be executed and delivered by facsimile signature or by email
in portable document format in two or more counterparts, each of which shall be deemed an original, but all of which together
shall constitute one and the same instrument.
