LOCK-UP AGREEMENT

 

THIS LOCK-UP AGREEMENT (this “Agreement”)
is made and entered into as of August 26, 2021 between (i) Nexters Inc., a British Virgin Islands business company (“Pubco”)
and (ii) the undersigned (the “Holder”). Pubco and the Holder are sometimes referred to herein individually as
a “Party” and, collectively, as the “Parties”. Any capitalized term used but not defined in this
Agreement will have the meaning ascribed to such term in the Business Combination Agreement (as defined below).

 

WHEREAS, Kismet Acquisition One Corp,
Pubco, Nexters Global Ltd. and the Holder, among others, entered into a business combination agreement, dated as of January 31,
2021, as amended on July 17, 2021 and August 11, 2021 (the “Business Combination Agreement”), pursuant to which
the parties thereto shall consummate a series of transactions, including the exchange of all of the Purchaser Ordinary Shares owned
by the Holder into a corresponding number of Pubco Ordinary Shares determined in accordance with the Business Combination
Agreement.

 

WHEREAS, pursuant to the Business Combination
Agreement, and in view of the valuable consideration to be received by the Holder thereunder, Pubco and the Holder desire to enter into
this Agreement, pursuant to which the Pubco Ordinary Shares to be received by the Holder pursuant to the Business Combination Agreement
(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.   Lock-Up Provisions.

 

(a)   The Holder agrees that it shall
not effectuate a Transfer of the Pubco Ordinary Shares that are held by the Holder during the period commencing from the Share Acquisition
Closing until the earlier to occur of (i) one (1) year after the Share Acquisition Closing, (ii) one-hundred and fifty
(150) days after the Share Acquisition Closing, if the closing price of the Pubco Ordinary Shares during such period equals or exceeds
Twelve Dollars ($12.00) per share (as adjusted for share splits, share dividends, reorganizations and recapitalizations) for any twenty
(20) trading days within any thirty (30) trading day period and (iii) a date after the Share Acquisition Closing on which Pubco consummates
a subsequent liquidation, merger, share exchange or other similar transaction which results in all of the Pubco’s shareholders having
the right to exchange their Pubco Ordinary Shares for cash, securities or other property (the “Lock-up Period”).

 

(b)   Notwithstanding the provisions
set forth in Section 1(a), Transfers of the Pubco Ordinary Shares that are held by the Holder (and that have complied with this Section 1(b))
are permitted (i) to Pubco’s officers or directors, any Affiliates or immediate family members of any of Pubco’s officers
or directors, any members of the Holder, or any Affiliates of the Holder, (ii) by gift to a member of the Holder’s immediate
family or to a trust, the beneficiary of which is a member of the Holder’s immediate family, an Affiliate of such person or to a
charitable organization, (iii) by virtue of the laws of descent and distribution upon death, (iv) pursuant to a qualified domestic
relations order or in connection with a divorce settlement, (v) by virtue of the laws of the Holder’s jurisdiction of incorporation
or organization, the Holder’s organizational documents or the rights attaching to the equity interests in the Holder upon dissolution
of the Holder, (vi) the exercise of any options, warrants or other convertible securities to purchase Pubco Ordinary Shares (which
exercises may be effected on a cashless basis to the extent the instruments representing such options or warrants permit exercises on
a cashless basis); provided, that any Pubco Ordinary Shares issued upon such exercise shall be subject to the Lock-Up Period,
(vii) Transfers to the Holder to satisfy tax withholding obligations pursuant to the Holder’s equity incentive plans or arrangements,
and (viii) in connection with any bona fide mortgage, pledge or encumbrance to a financial institution in connection with any bona
fide loan or debt transaction or enforcement thereunder, including foreclosure thereof, provided, that in clauses (i) through
(iv), the transferee must enter into a written agreement in substantially the form of this Agreement, agreeing to be bound by the terms
of the Lock-up Period. If dividends are declared and payable in Pubco Ordinary Shares, such dividends will also be subject to the Lock-up
Period.

 

    

     

    

 

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

 

(d)   During the Lock-Up Period,
each certificate evidencing any Restricted Securities (if any are issued) 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 AUGUST 26, 2021, BY AND AMONG THE ISSUER OF SUCH SECURITIES
(THE “ISSUER”) 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,
the Holder shall retain all of its rights as a shareholder of Pubco with respect to the Restricted Securities during the Lock-Up Period,
including the right to vote any Restricted Securities.

 

(f)   For the purposes of this Section 1,
 “Transfer” shall mean the (a) sale of, offer to sell, contract or agreement to sell, hypothecate, pledge, grant of any
option to purchase or otherwise dispose of or agreement to dispose of, directly or indirectly, or establishment or increase of a put equivalent
position or liquidation with respect to or decrease of a call equivalent position within the meaning of Section 16 of the Securities
Exchange Act of 1934, as amended, and the rules and regulations of the U.S. Securities and Exchange Commission promulgated thereunder
with respect to, any security, (b) entry into any swap or other arrangement that transfers to another, in whole or in part, any of
the economic consequences of ownership of any security, whether any such transaction is to be settled by delivery of such securities,
in cash or otherwise, or (c) public announcement of any intention to effect any transaction specified in clause (a) or (b).

(i)   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 Pubco and the 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.

 

(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.   The
Holder acknowledges that its obligations under this Agreement are unique, recognizes and affirms that in the event of a breach of this
Agreement by the Holder, money damages will be inadequate and Pubco will have no 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 the Holder in accordance with their specific
terms or were otherwise breached. Accordingly, Pubco shall be entitled to an injunction or restraining order to prevent breaches of this
Agreement by the 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)   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 Business Combination
Agreement or any Ancillary Document. Notwithstanding the foregoing, nothing in this Agreement shall limit any of the rights or remedies
of Pubco or any of the obligations of the Holder under any other agreement between the Holder and Pubco or any certificate or instrument
executed by the Holder in favor of Pubco, and nothing in any other agreement, certificate or instrument shall limit any of the rights
or remedies of Pubco or any of the obligations of the Holder under this Agreement.

 

(m)   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.

 

(n)   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.

issuable upon the exercise or conversion of the Pubco Warrants) that are held by the Holder during the period commencing from the Merger
Closing until the earlier to occur of (i) one (1) year after the Share Acquisition Closing, (ii) one-hundred and fifty
(150) days after the Share Acquisition Closing, if the closing price of the Pubco Ordinary Shares during such period equals or exceeds

laws of the Holder’s jurisdiction of incorporation or organization, the Holder’s organizational documents or the rights attaching
to the equity interests in the Holder upon dissolution of the Holder, (vi) the exercise of any options, warrants or other convertible
securities to purchase Pubco Ordinary Shares (which exercises may be effected on a cashless basis to the extent the instruments representing
such options or warrants permit exercises on a cashless basis); provided, that any Pubco Ordinary Shares issued upon such exercise
shall be subject to the applicable Lock-Up Period, (vii) Transfers to the Holder to satisfy tax withholding obligations pursuant

Shares, such dividends will also be subject to the applicable Lock-up Period.

 

(d)            If

this Section 1, Pubco may impose stop-transfer instructions with respect to the Restricted Securities of the Holder (and any
permitted transferees and assigns thereof) until the end of the applicable Lock-Up Period.

(f)            For
the avoidance of any doubt, the Holder shall retain all of its rights as a shareholder of Pubco with respect to the Restricted Securities

hereto and their respective permitted successors and assigns. Except as otherwise provided in this Agreement, this Agreement and all obligations
of the Parties are personal to the Parties and may not be transferred or delegated by the Parties at any time.

 

(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 or entity that is not
a Party hereto or thereto or a successor or permitted assign of such a Party.

Law; Jurisdiction. This Agreement shall be governed by and construed in accordance with the Laws of the State of Delaware, without

masculine, feminine or neuter forms, and the singular form of nouns, pronouns and verbs shall include the plural and vice versa; (ii) “including”

(i)            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 Pubco and the 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.

 

(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. The Holder acknowledges that its obligations under this Agreement are unique, recognizes and affirms that in the event
of a breach of this Agreement by the Holder, money damages will be inadequate and Pubco will have no 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 the Holder in accordance
with their specific terms or were otherwise breached. Accordingly, Pubco shall be entitled to an injunction or restraining order to prevent
breaches of this Agreement by the 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)            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 Business Combination Agreement or any Ancillary Document. Notwithstanding the foregoing, nothing in this Agreement shall limit
any of the rights or remedies of Pubco or any of the obligations of the Holder under any other agreement between the Holder and Pubco
or any certificate or instrument executed by the Holder in favor of Pubco, and nothing in any other agreement, certificate or instrument
shall limit any of the rights or remedies of Pubco or any of the obligations of the Holder under this Agreement.

 

(m)           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.

 

(n)           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.
