AGREEMENT

 

		1.	Agreement to Retain Shares.

Transfer; No Inconsistent Arrangements. From the date of this Agreement until 6:00 a.m. Eastern Time on the day following
the record date set by the Company’s Board to determine the shares entitled to vote at the Company Stockholder Meeting, other than

of, or enter into any derivative arrangement with respect to, any Shares, or any right or interest therein (or consent to any of the foregoing)
(each, a “Transfer”), other than Permitted Transfers;

 

     

     

    

 

(ii)         create
any lien, claim, pledge, grant, hypothecation, obligation, option, charge, proxy, voting trust or other encumbrance or restriction on
title, transfer or exercise of any rights of a Holder in respect of such Shares (“Lien”) on the Shares, except Liens
arising under or pursuant to, or imposed by, applicable Law, this Agreement, the Merger Agreement, the Transactions, any Company Compensatory
Awards, any employee benefit plan of the Company, any restrictions under applicable federal or state securities laws, or security interests
or other encumbrances incurred in connection with standard margin account arrangements) (“Permitted Liens”);

 

(iii)        deposit

of attorney or other authorization or consent in, or with respect to, the Shares; or

 

(iv)        enter
into any Contract with respect to any Transfer or Lien prohibited by this Section 1.

 

Notwithstanding
the foregoing, a Holder may: Transfer Shares (w) in connection with the exercise, vesting or settlement of Company Compensatory Awards
(including the net settlement of such equity or sale of underlying shares of Company Common Stock in order to pay any exercise price and
any tax withholding obligations in connection therewith), (x) to any Affiliate, Subsidiary, partner or member of the Holder or to
a trust established for the benefit of the Holder or any of its Affiliates, (y) if such Holder is an individual, (i) to any
member of such Holder’s immediate family or any member of such Holder’s immediate family or (ii) to any person or entity
if and to the extent required by any non-consensual legal order, by divorce decree or by will, intestacy or other similar law (provided,
however, that in case of the foregoing clauses (x) and (y)(i), as a condition to such Transfer, the recipient agrees in writing to
be bound by this Agreement and delivers a copy of such executed written agreement to Parent prior to the consummation of such Transfer);
or (z) with Parent’s prior written consent (such exceptions set forth in clauses (w) through (z), a “Permitted
Transfer”). Nothing in this Agreement shall prohibit direct or indirect Transfers of equity or other interests in a Holder.

the Termination Time, whether pursuant to purchase, exercise, exchange or conversion of, or other transaction involving, any and all warrants,
options, rights or other securities (“New Shares”), shall be subject to the terms and conditions of this Agreement
to the same extent as if they comprised the Shares as of the date hereof.

 

(c)           Adjustments.
In the event of any stock split, stock dividend, merger, reorganization, recapitalization, reclassification, combination, exchange of
shares or similar transaction with respect to the capital stock of the Company that affects the Shares, the terms of this Agreement shall
apply to the resulting securities and such resulting securities shall constitute “Shares” for all purposes hereunder.

2.            Agreement
to Vote Shares. Subject to the terms of this Agreement, each Holder irrevocably and unconditionally agrees that, from the date of
this Agreement and until the Termination Time, at every meeting of the stockholders of the Company, however called, with respect to any
of the following, and at every adjournment or postponement thereof, or in any other circumstances upon which a vote, consent or other
approval of all or some of the stockholders of the Company is sought, and on every action or approval proposed to be taken by written
consent of the stockholders of the Company with respect to any of the following, each Holder shall appear at such meeting (in person or
by proxy) or otherwise cause the Shares to be counted as present for purposes of calculating a quorum and shall vote (or cause to be voted)
or deliver a written consent (or cause a written consent to be delivered) covering all of the Shares that such Holder is entitled to so
vote, in each case to the fullest extent that such Holder’s Shares are entitled to vote: (1) in favor of the Merger and the
other Transactions contemplated by the Merger Agreement and in favor of adopting the Merger Agreement and (2) against (a) any
action that would (or would be reasonably expected to) directly result in a breach of any covenant, representation or warranty or any
other obligation or agreement of the Company contained in the Merger Agreement or of any Holder contained in this Agreement, or (b) that
would result in any condition to the consummation of the Merger set forth in the Merger Agreement not being satisfied, (c) any other
action, transaction, proposal, or agreement relating to the Company that would (or would reasonably be expected to) prevent, nullify or
materially impede, interfere with, frustrate, delay, postpone or adversely affect the Transactions, (d) any change in the present
capitalization of the Company or any amendment of the certificate of incorporation of the Company prohibited by the Merger Agreement,
or (e) subject to the right to terminate this Agreement pursuant to Section 8(f), any Acquisition Proposal. Each
Holder shall retain at all times the right to vote the Shares in such Holder’s sole discretion, and without any other limitation,
on any matters other than those set forth in this Section 2 that are at any time or from time to time presented for consideration
to the Company’s stockholders. For the avoidance of doubt, nothing in this Agreement shall require any Holder to vote, cause to
be voted or otherwise consent to any amendment to the Merger Agreement (including any schedule or exhibit thereto) or the taking of any
action that could result in the amendment, modification or a waiver of a provision therein, in any such case, in a manner that (i) decreases
the amount or changes the form of the Merger Consideration, (ii) imposes any material restrictions or additional conditions on the
consummation of the Merger or the other Transactions, or the payment of the Merger Consideration to stockholders, (iii) extends the
Termination Date (as defined below) or (iv) amends any other term or condition of the Merger Agreement that is adverse in any material
respect to any Holder’s rights under the Merger Agreement.

 

		3.	Grant of Irrevocable Proxy; Appointment of Proxy.

 

(a)           Without
in any way limiting any Holder’s right to vote the Shares in its sole discretion on any other matters that may be submitted to a
Holder vote, consent or other approval, each Holder hereby irrevocably grants to, and appoints, Parent and any duly appointed designee
thereof, such Holder’s proxy and attorney-in-fact (with full power of substitution), for and in the name, place and stead of such
Holder, to attend any meeting of the stockholders of the Company on behalf of such Holder, to include such Shares in any computation for
purposes of establishing a quorum at any meeting of Holders of the Company, and to vote all Shares beneficially owned or controlled by
such Holder (the “Vote Shares”), or to grant a consent or approval in respect of the Vote Shares, in connection with
any meeting of the Holders of the Company or any action by written consent in lieu of a meeting of Holders of the Company, in accordance
with the provisions of Section 2.

 

(b)           Each
Holder hereby represents that any proxies heretofore given in respect of the Shares with respect to any of the matters set forth in Section 2,
if any, are revocable, and hereby revokes such proxies.

 

(c)           Each
Holder hereby affirms that the irrevocable proxy set forth in this Section 3 is given in connection with the execution of
the Merger Agreement, and that such irrevocable proxy is given to secure the performance of the duties of such Holder under this Agreement.
Each Holder hereby further affirms that the irrevocable proxy is coupled with an interest and is intended to be irrevocable in accordance
with the provisions of Section 212 of the DGCL during the term of this Agreement. If during the term of this Agreement for any reason
the proxy granted herein is not irrevocable, then such Holder agrees that it shall vote its Shares in accordance with Section 2
above as instructed by Parent in writing. The parties agree that the foregoing shall be a voting agreement created under Section 218
of the DGCL.

		9.	Miscellaneous.

 

(a)           Entire
Agreement; Amendments and Waivers. This Agreement, together with Schedule 1 and the other documents and certificates contemplated
hereby, constitutes the entire agreement and supersedes all contemporaneous and prior agreements and understandings, both written and
oral, among or between any of the parties with respect to the subject matter hereof. This Agreement may not be amended except by an instrument
in writing signed on behalf of each of the parties. No failure on the part of any party to exercise any power, right, privilege or remedy
under this Agreement, and no delay on the part of any party in exercising any power, right, privilege or remedy under this Agreement,
shall operate as a waiver of such power, right, privilege or remedy; and no single or partial exercise of any such power, right, privilege
or remedy shall preclude any other or further exercise thereof or of any other power, right, privilege or remedy. No party shall be deemed
to have waived any claim arising out of this Agreement, or any power, right, privilege or remedy under this Agreement, unless the waiver
of such claim, power, right, privilege or remedy is expressly set forth in a written instrument duly executed and delivered on behalf
of such party; and any such waiver shall not be applicable or have any effect except in the specific instance in which it is given.

 

(b)           Governing

govern under applicable principles of conflicts of Laws of the State of Delaware. In any action or proceeding arising out of or relating
to this Agreement: (i) each of the parties irrevocably and unconditionally consents and submits to the exclusive jurisdiction and
venue of the Court of Chancery of the State of Delaware and any state appellate court therefrom or, if such court lacks subject matter
jurisdiction, the United States District Court sitting in New Castle County in the State of Delaware (it being agreed that the consents
to jurisdiction and venue set forth in this Section 9(b) shall not constitute general consents to service of process
in the State of Delaware and shall have no effect for any purpose except as provided in this paragraph and shall not be deemed to confer
rights on any Person other than the parties); and (ii) each of the parties irrevocably consents to service of process by first class
certified mail, return receipt requested, postage prepaid, to the address at which such party is to receive notice in accordance with
Section 9(f). Each of the parties hereby irrevocably and unconditionally waives any objection to the laying of venue of any
action, suit or proceeding arising out of this Agreement in the Court of Chancery of the State of Delaware and any state appellate court
therefrom or, if such court lacks subject matter jurisdiction, the United States District Court sitting in New Castle County in the State
of Delaware, and hereby further irrevocably and unconditionally waives and agrees not to plead or claim in any such court that any such
action, suit or proceeding brought in any such court has been brought in an inconvenient forum (including, any claim based on the doctrine
of forum non conveniens or any similar doctrine). The parties agree that a final judgment in any such action or proceeding shall
be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by applicable Laws; provided,
however, that nothing in the foregoing shall restrict any party’s rights to seek any post-judgment relief regarding, or any
appeal from, such final trial court judgment.

THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER, (II) EACH PARTY UNDERSTANDS AND HAS CONSIDERED THE IMPLICATION OF
THIS WAIVER, (III) EACH PARTY MAKES THIS WAIVER VOLUNTARILY AND (IV) EACH OTHER PARTY HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT

in any other situation or in any other jurisdiction. If a final judgment of a court of competent jurisdiction declares that any term or
other provision of this Agreement is invalid, illegal, or incapable of being enforced by any rule of law or public policy, the remaining

(h)           Binding
Effect, Assignment and Transfer. Each Holder agrees with, and covenants to, Parent and Merger Sub that (i) this Agreement and
the obligations hereunder shall attach to the Holder’s Shares and shall be binding upon any person or entity to which legal or beneficial

or assigns and (ii) it shall not request that the Company register the Transfer (book-entry or otherwise) of any Company Stock Certificate
or Book Entry Share representing any or all of the Holder’s Shares, unless such Transfer is made in compliance with this Agreement.
This Agreement shall be binding upon, and shall be enforceable by and inure solely to the benefit of, the parties and their respective
successors and permitted assigns; provided, however, that neither this Agreement nor any of the rights, interests, covenants or
agreements hereunder may be assigned, in whole or in part, without the prior written consent of the other parties, and any attempted assignment
of this Agreement or any of such rights without such consent shall be void ab initio and of no effect. Notwithstanding the foregoing,

Third Party Beneficiaries. Except as set forth in Section 9(n), nothing in this Agreement, express or implied, is intended

this Agreement.

 

(j)            Specific
Performance. The parties to this Agreement agree that irreparable damage for which monetary damages, even if available, would not
be an adequate remedy, would occur in the event that the parties do not perform their obligations under the provisions of this Agreement
in accordance with its specified terms or otherwise breach such provisions. Subject to the terms and conditions of this Section 9(j),
the parties acknowledge and agree that (i) each party shall be entitled to an injunction or injunctions, specific performance, or
other equitable relief, to prevent breaches or threatened breaches of this Agreement by another party and to enforce specifically the
performance of the terms and provisions hereof in the courts described in Section 9(b) without proof of actual damages
or otherwise, this being in addition to any other remedy to which they are entitled under this Agreement at Law or in equity and (ii) the
right of specific performance is an integral part of the Transactions contemplated hereby and without that right, neither the Holder,
Company, Parent, nor Merger Sub would have entered into this Agreement. Each of the parties agrees that it will not oppose the granting
of an injunction, specific performance and other equitable relief on the basis that the other parties have an adequate remedy at law or
an award of specific performance is not an appropriate remedy for any reason at law or equity. The parties acknowledge and agree that
any party seeking an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions
of this Agreement in accordance with this Section 9(j) shall not be required to provide any bond or other security in
connection with the seeking of any such injunction or specific performance.

 

(k)            Disclosure.
Subject to the terms of this paragraph, each Holder consents to and shall permit the Company, Parent and Merger Sub to publish and disclose
in all documents and schedules filed with the SEC or other Governmental Entity, and any press release or other disclosure document, or
any other disclosure document in connection with the Merger or any of the other transactions contemplated by the Merger Agreement or this
Agreement that, in each case, Parent or Merger Sub reasonably determines to be necessary in connection with the Merger and any other Transactions
contemplated by the Merger Agreement, relating solely to such Holder’s identity and ownership of Shares and the nature of such Holder’s
commitments, arrangements, and understandings under this Agreement. The Company, Parent or Merger Sub, as applicable, shall give the Holder
notice prior to any such disclosure and the Holder shall use reasonable best efforts to reasonably promptly provide the Company, Parent
or Merger Sub, as applicable, any information that is legally required to be disclosed in such disclosure or publication. Each of Parent
and Merger Sub shall consider all reasonable comments provided by the Holder with respect to any such disclosure or publication. Each
Holder acknowledges that, subject to the terms of this Section 9(k), Parent and Merger Sub may, in Parent’s sole discretion,
file this Agreement or a form hereof with the SEC. Each Holder agrees to promptly notify Parent if it becomes aware of any required corrections
with respect to any written information regarding this Agreement supplied by it specifically for use in any such disclosure document,
if and to the extent that the Holder shall become aware that any such information shall have become false or misleading in any material
respect. Parent hereby consents to and authorizes the publication and disclosure of this Agreement by any Holder in any disclosure document
required by applicable Law (including any Schedule 13D).

(l)            No
Agreement Until Executed. Irrespective of negotiations among the parties or the exchanging of drafts of this Agreement, this
Agreement shall not constitute or be deemed to evidence a contract, agreement, arrangement or understanding between the parties to this
Agreement unless and until: (i) the Merger Agreement is executed by all parties to the Merger Agreement; and (ii) this Agreement
is executed by all parties to this Agreement.

 

(m)          Directors
and Officers. Each Holder signs this Agreement solely in such Holder’s capacity as a stockholder of the Company, and not, if
applicable, in such Holder’s capacity as a director, officer, employee or agent of the Company. Notwithstanding any provision of
this Agreement to the contrary, nothing in this Agreement shall in any way limit or restrict a Holder, or any Affiliate, director, officer,
partner, employee or designee of a Holder, who is a director or officer of the Company or any of its Subsidiaries in the taking of any
actions (or failure to act) in his or her capacity or fulfilling the obligations of such office, in the exercise of his or her fiduciary
duties or prevent or be construed to create any obligation on the part of any director or officer of the Company from taking any action
in his or her capacity as such, including by voting, in his or her capacity as a director, officer, employee or agent of the Company or
any of its Subsidiaries’, in a Holder’s, or its Affiliates’, employee’s or designee’s, sole discretion on
any matter, and no action taken in any such capacity as an officer or director of the Company shall constitute a breach of this Agreement.

 

(n)           Non-Recourse.
All Legal Proceedings (whether in Contract or in tort, in law or in equity) that may be based upon, arise out of or relate to this Agreement
or the negotiation, execution, performance or non-performance of this Agreement (including any representation or warranty made in or in
connection with this Agreement or as an inducement to enter into this Agreement) may be made by any party hereto only against the Persons
that are expressly identified as parties hereto or thereto. No Person who is not a named party to this Agreement, including any director,
officer, employee, incorporator, member, partner, stockholder, Affiliate, agent, attorney or Representative of any named party to this
Agreement that is not itself a named party to this Agreement (“Non-Party Affiliates”), shall have any liability (whether
in Contract or in tort, in law or in equity, or based upon any theory that seeks to impose liability of an entity party against its owners
or Affiliates) to any party to this Agreement for any obligations or liabilities arising under, in connection with or related to this
Agreement or for any claim based on, in respect of, or by reason of this Agreement or its negotiation or execution; and each party hereto
or thereto waives and releases all such liabilities, claims and obligations against any such Non-Party Affiliates. The parties acknowledge
and agree that the Non-Party Affiliates are intended third-party beneficiaries of this Section 9(n). Nothing in this Agreement
precludes the parties or any Non-Party Affiliates from exercising any rights, and nothing in this Agreement shall limit the liability
or obligations of any Non-Party Affiliates, in each case under the Merger Agreement or any other agreement to which they are specifically
a party or an express third party beneficiary thereof. This Section 9(n) is subject to, and does not alter the scope
or application of, Section 9(j).

 

(o)           Expenses.
All fees and expenses incurred in connection with this Agreement and the Transactions shall be paid by the party incurring such
expenses, whether or not the Merger is consummated.

 

(p)           No
Ownership Interest. Nothing contained in this Agreement shall be deemed to vest in Parent or Merger Sub any direct or indirect ownership
or incidence of ownership of or with respect to the Shares. All rights, ownership and economic benefits of and relating to the
Shares shall remain vested in and belong to each applicable Holder. Neither Parent nor Merger Sub shall have any authority to manage,
direct, restrict, regulate, govern, or administer any of the policies or operations of the Company or exercise any power or authority
to direct such Holder in the voting of any of the Shares, except as otherwise provided in this Agreement.

 

(q)           Holder
Obligations Several and Not Joint. The obligations of each Holder hereunder shall be several and not joint, and no Holder shall
be liable for any breach of the terms of this Agreement by any other Holder.

(r)            Mutual
Drafting. Each party has participated in the drafting of this Agreement, which each party acknowledges is the result of extensive
negotiations between the parties. Accordingly, this Agreement will be construed without regard to any presumption or rule requiring
construction or interpretation against the party drafting or causing any instrument to be drafted.

Assurances. Parent, Merger Sub and each Holder will execute and deliver, or cause to be executed and delivered, all further documents
and instruments necessary under applicable Law, to perform their respective obligations under this Agreement.

PROMISSORY NOTE

 

	$250,000.00	As of August 29, 2022

 

Gesher I Acquisition Corp.
(“Maker”) promises to pay to the order of Gesher I Sponsor, LLC or its successors or assigns (“Holder”)
the principal sum of Two Hundred Fifty Thousand Dollars and No Cents ($250,000.00) in lawful money of the United States of America, on
the terms and conditions described below.

 

1. Principal.
The principal balance of this Note shall be repayable on the consummation of the Maker’s initial merger, share exchange, asset acquisition,
stock purchase, recapitalization, reorganization or other similar business combination with one or more businesses or entities (a “Business
Combination”). Holder understands that if a Business Combination is not consummated, this Note will not be repaid and all amounts
owed hereunder will be forgiven except to the extent that the Maker has funds available to it outside of its trust account established
in connection with its initial public offering.

 

2. Interest.
No interest shall accrue on the unpaid principal balance of this Note.

 

3. Application
of Payments. All payments shall be applied first to payment in full of any costs incurred in the collection of any sum due under this
Note, including (without limitation) reasonable attorneys’ fees, then to the payment in full of any late charges and finally to
the reduction of the unpaid principal balance of this Note.

 

4. Events
of Default. The following shall constitute Events of Default:

 

(a) Failure
to Make Required Payments. Failure by Maker to pay the principal of this Note within five (5) business days following the date when
due.

 

(b) Voluntary
Bankruptcy, Etc. The commencement by Maker of a voluntary case under the Federal Bankruptcy Code, as now constituted or hereafter
amended, or any other applicable federal or state bankruptcy, insolvency, reorganization, rehabilitation or other similar law, or the
consent by it to the appointment of or taking possession by a receiver, liquidator, assignee, trustee, custodian, sequestrator (or other
similar official) of Maker or for any substantial part of its property, or the making by it of any assignment for the benefit of creditors,
or the failure of Maker generally to pay its debts as such debts become due, or the taking of corporate action by Maker in furtherance
of any of the foregoing.

 

(c) Involuntary
Bankruptcy, Etc. The entry of a decree or order for relief by a court having jurisdiction in the premises in respect of maker in an
involuntary case under the Federal Bankruptcy Code, as now or hereafter constituted, or any other applicable federal or state bankruptcy,
insolvency or other similar law, or appointing a receiver, liquidator, assignee, custodian, trustee, sequestrator (or similar official)
of Maker or for any substantial part of its property, or ordering the winding-up or liquidation of its affairs, and the continuance of
any such decree or order unstayed and in effect for a period of 60 consecutive days.

 

     

     

    

 

5. Remedies.

 

(a) Upon
the occurrence of an Event of Default specified in Section 4(a), Holder may, by written notice to Maker, declare this Note to be due and
payable, whereupon the principal amount of this Note, and all other amounts payable thereunder, shall become immediately due and payable
without presentment, demand, protest or other notice of any kind, all of which are hereby expressly waived, anything contained herein
or in the documents evidencing the same to the contrary notwithstanding.

 

(b) Upon
the occurrence of an Event of Default specified in Sections 4(b) and 4(c), the unpaid principal balance of, and all other sums payable
with regard to, this Note shall automatically and immediately become due and payable, in all cases without any action on the part of Holder.

 

6. Conversion.
Upon consummation of a Business Combination, the Holder shall have the option, but not the obligation, to convert the principal balance
of this Note, in whole or in part at the option of the Holder, into warrants (“Warrants”) of the Maker at a price of
$1.00 per Warrant; provided, however, that the Holder shall be permitted to convert this Note only if the shareholders of the Maker or
the target business in any such Business Combination, whichever may be required in connection with such Business Combination, have approved
the issuance of the Warrants to the Holder if such approval is necessary under applicable law. The Warrants will be identical to the “private
warrants” (as such term is defined in the Maker’s final prospectus for its initial public offering, dated October 12, 2021).
As promptly as reasonably practicable after notice by Holder to Maker to convert the principal balance of this Note, which must be made
at least 24 hours prior to the consummation of the Business Combination, and after Holder’s surrender of this Note, Maker shall
have issued and delivered to Holder, without any charge to Holder, a certificate or certificates (issued in the name(s) requested by Holder)
for the number of Warrants of Maker issuable upon the conversion of this Note.

 

7. Waivers.
Maker and all endorsers and guarantors of, and sureties for, this Note waive presentment for payment, demand, notice of dishonor, protest,
and notice of protest with regard to the Note, all errors, defects and imperfections in any proceedings instituted by Holder under the
terms of this Note, and all benefits that might accrue to Maker by virtue of any present or future laws exempting any property, real or
personal, or any part of the proceeds arising from any sale of any such property, from attachment, levy or sale under execution, or providing
for any stay of execution, exemption from civil process, or extension of time for payment; and Maker agrees that any real estate that
may be levied upon pursuant to a judgment obtained by virtue hereof, on any writ of execution issued hereon, may be sold upon any such
writ in whole or in part in any order desired by Holder.

 

8. Unconditional
Liability. Maker hereby waives all notices in connection with the delivery, acceptance, performance, default, or enforcement of the
payment of this Note, and agrees that its liability shall be unconditional, without regard to the liability of any other party, and shall
not be affected in any manner by any indulgence, extension of time, renewal, waiver or modification granted or consented to by Holder,
and consents to any and all extensions of time, renewals, waivers, or modifications that may be granted by Holder with respect to the
payment or other provisions of this Note, and agree that additional makers, endorsers, guarantors, or sureties may become parties hereto
without notice to them or affecting their liability hereunder.
