 IT IS AGREED AS FOLLOWS: 

Article 1: Axisparc 
  

	 	1.1.	 Axisparc is a business center open to businesses. It consists of 4 zones. 

 

	 	•	 	 Zone 1: Axisparc Offices: 9 buildings totaling more than 30,000 m2 of offices. 

 

	 	•	 	 Zone 2: Axisparc Service Center: 1 building that contains a restaurant + fitness center + conference rooms.

	 	1.2.	 The building concerned by this lease is located in zone 3. 

This zone as well as zone 4 are the subject of a co-ownership arrangement and the co-ownership regulations titled Axisparc High Tech specifications (see Appendix 1), which form an integral part of the obligations for the users and occupants of the premises. 

The percentages of the lease concerned in the building rue Edouard Belin 12 are:

 Article 2: Allocated space 

a) The Lessor leases to the Lessee, which accepts, in the current state and perfectly known to the Lessee: 

 

	•	 	 An office space located on the first floor, as indicated on the plan in Appendix 2; 

 

	•	 	 22 uncovered parking spaces, bearing Nos. 1 through 12 and 18 through 27, located on the first floor, as
indicated on the plan in Appendix 3. 

 Hereinafter referred to as the “Leased Premises,” 

 

	b)	 The lease also includes the right for the Lessee, its staff, the third parties with whom it deals, to
use, at the same time as the Lessor and any others authorized by it, the roads, pathways, serving for access to the business center that serve the leased premises so as to enter it and to allow access to all vehicles necessary for the operation of
its business. 

 Article 3: Intended use 

The premises are leased for production, laboratory and office use. 

Throughout the term of the lease, the Lessee undertakes to comply with this purpose. 

No modification to this purpose may be made by the Lessee, without the prior written consent of the Lessor, which may always refuse it for just cause. It is
expressly agreed that the intended use of the premises is an essential condition of this lease, without which the Lessor would not have entered into the contract. 

Under no circumstances may the leased premises be allocated to the exercise of a retail business or the activity of a craftsman directly in contact with the
public, even if they are used as demonstration rooms, so that this lease is not and may never be governed by the Law of April 30, 1951, on commercial leases. 

The Lessee is prohibited from exercising any activity in the leased premises that could disturb the tranquility and peaceful enjoyment of its neighbors and
undertakes to comply with the specifications of Axisparc High Tech. 
 Each parking space is reserved exclusively for parking vehicles. It is strictly
forbidden to store goods, wash or maintain vehicles there. The Lessee is not authorized to organize public sales there. 
 The Lessor reserves the right to
modify or swap the designated parking spaces, if work or changes among the tenants, the security or internal organization of the building so require, and as such, after the Lessor has notified the tenant of the change or swap at least one
(1) week in advance. 
 Article 4: Term 

This lease will take effect on July 1st 2020. 

  
 2 

 It is concluded for a term of nine consecutive years and will expire on June 30, 2029 without notice, by the
simple expiry of the term. At the end of the lease, the continuation of occupancy of the leased premises may not under any circumstances be interpreted as constituting tacit renewal. 

The lessor shall have the option of waiving this lease agreement at the end of the first three-year period and at the end of the second three-year period, by
giving notice by registered letter sent to the other party, at least six months before the end of the term.

 Article 6: Adjustment of the rent 

 

	6.1.	 The indexing will be done in accordance with the following: 

 

	6.1.1.	 The amount of the rent is linked to the Kingdom’s health index as provided for in the R.D. of 12/24/1993.

  

	6.1.2.	 Without ever being permitted to be lower than the last indexed rent, the rent will be automatically and ipso
jure reviewed each year on the anniversary date of taking on the lease based on the index of the month preceding the revision according to the formula below, the base index being that of the month preceding the signature hereof, according to Article
1728 bis of the Civil Code (base index = May 2020 = 110.10). 

 New rent = Base rent × Index of the month
preceding the month of the review 

                        
                                         
   Base index 
  

	6.1.3.	 In the event that the basis for calculating the official health index is modified or removed, the parties
expressly agree that the amount of the rent will be attached to the conversion rate published by the “Moniteur Belge” or any other system that would replace this index. 

 

	6.2.	 It is expressly agreed that any waiver on the Lessor’s part relating to the increases resulting from this
Article may not be established other than by a written acknowledgement signed by it.

Article 9: Use of the premises 
 The Lessee
undertakes to enjoy the premises in a “prudent and responsible manner” and in particular to comply with the requirements of Article 10 below with regard to the use of the leased premises and other parts of the building. 

The maximum loads allowed on the floors, including the weight of the partitions, may not exceed 350 kg/m2, unless stipulated otherwise in the technical
documents. 
 The placement, installation and use of telephone installations, radio and television devices, teletype machines and other technical devices
within the leased premises will be at the exclusive risk and expense of the Lessee and under its full and exclusive responsibility. 
 If the placement of
the aforementioned devices is likely to result in work outside the building, or in the communal areas, the Lessee must request prior written authorization from the Lessor. The Lessee shall ensure in its use of said devices that it does not disrupt
the enjoyment of the other occupants. These works will be carried out at the exclusive expense of the Lessee. 
 In accordance with safety regulations, fire
doors can never be kept blocked in the open position. 
 If the Lessee does not comply with the obligations for the maintenance and repair of the leased
premises, the Lessor, without prejudice to its other rights, shall have the right to enter the leased premises and to perform there, at the expense of the Lessee, all the work that the latter has failed to do. 

Article 10: Specifications for Axisparc High Tech 

The Lessee undertakes to comply with the requirements of the specifications, of which it acknowledges having been informed and declares that it accepts them.

 These may be supplemented, modified or amended by the joint owners of Axisparc High Tech in particular in order to safeguard the standing of the
buildings, improve the conditions of their operation or to provide for a better distribution of clauses between the internal regulations and the other documents to be drawn up as part of a new possible
co-ownership arrangement (basic deed, internal regulations). 
 Article 11: Entry premises inventory

 An entry premises inventory definitively committing the parties will be drawn up before taking possession and at the latest when the keys are
handed over to the Lessee or before the refurbishment of the premises on behalf of the Lessee. 

  
 6 

 This premises inventory will be prepared either by an expert appointed by mutual agreement by the parties, or by
two experts, each party appointing and honoring its own. The fees of the expert(s) will be covered equally by both parties. 
 It is expressly agreed that
the premises will be leased and described in landscape form (i.e. without partitioning, cabling or private equipment). It is expressly agreed between the parties that the partitioning, wiring and private equipment will be, for the drawing up of the
exit premises inventory, considered as transformations having been carried out by the Lessee during the lease, within the meaning given to this expression by Article 13 below. 

Article 12: Restoration 
 An exit premises
inventory will be drawn up, following the same procedure as described in the previous provision, in order to have the amount of the rental damage and any unavailability compensation prepared by the expert(s). The decision(s) of the expert(s) both
upon entry and exit will definitively bind the parties. 
 At the end of the lease, the Lessee must restore the leased premises as it received them
according to the entry premises inventory except for normal wear and tear, but without prejudice to the provisions of Article 13 below. 
 It is expressly
stipulated that the damage that would be caused by the installation, modifications and removal of partitions do not constitute normal use and are the responsibility of the Lessee, notwithstanding normal wear and tear and use. 

The necessary restoration work will be carried out before the expiry of the lease by the Lessee. Failing this, the Lessee shall be liable, without prejudice
to its other obligations, for compensation equivalent to the rent in force at the end of the lease and for the charges and taxes, for the time frame estimated by the expert(s) for the restoration of the leased premises. This compensation will not be
due if the delay in the restoration is attributable, in whole or in part, to the Lessor. 
 It is, as far as necessary, specified that if, for one reason or
another, this lease should be renewed and/or should continue after the expiry of the term referred to in Article 3 and that no new premises inventory should be drawn up on this occasion, the premises inventory drawn up at the time of taking effect
hereof, as well as any amendments thereto, will be used as a basis for the determination of rental damage upon exit. 
 Article 13: Refurbishment,
transformation and modification 
 All works, refurbishments, embellishments, transformations, placement of advertising panels and/or satellite
antennas, new layouts of the premises are subject to the prior, express and written authorization of the Lessor, which may not withhold its consent without reasonable cause. 

With its request, the Lessee shall submit to the Lessor the plans of the works that it is prepared to carry out or have carried out in the leased premises, as
well as a detailed description of them, the specifications and the complete list of materials that it intends to implement. It is in any event prohibited for the Lessee to use materials that, although meeting safety standards, are considered
potentially dangerous. 

  
 7 

 The Lessor must communicate its point of view to the lessee within 30 days. 

If, during and/or subsequent execution, one of the materials used no longer meets national or European safety standards and/or is downgraded, the Lessee shall
be required to provide for its replacement as soon as possible after the downgrading or risk has been brought to its attention. The removal work will be carried out by a firm specially approved for this purpose. 

It should be noted that the removal work may affect parts of the building other than those rented herein (e.g. the ventilation of the building in the event of
removal of materials declared dangerous). If the Lessee fails to satisfy it 15 days after a formal notice sent by the Lessor has remained without effect, the Lessor will be authorized to commission the replacement itself at the Lessee’s
expense, which will be required to reimburse it upon simple presentation of a paid invoice. 
 The Lessor shall have the right to have the necessary work
carried out urgently and to legally demand the reimbursement of its disbursements in this regard, insofar as this work is incumbent on the Lessee according to Article 1720, paragraph 2, of the Belgian Civil Code and that the Lessor has sent a
request for reimbursement, containing details of the costs incurred, by registered letter to the Lessee and that this request has remained unanswered by the Lessee for fifteen (15) calendar days. The Lessor undertakes to notify the Lessee of
the works before their execution. 
 The Lessor reserves the right to monitor, at its own expense, the work that it would have authorized and may require
that the Lessee provide proof of sufficient insurance. 
 In addition, for the completion of all work for which it would have been authorized, the Lessee
must comply with the regulations in force, in particular the town planning, operating or environmental permit and the safety regulations that may apply to the building, including the safety standards required by the insurer, the Lessor and the fire
services. 
 In the event that significant changes would be made to the leased premises by the Lessee during the lease and if the Lessor agrees that the
leased premises are to be returned in their condition as amended as a result of these modification works, the Lessor reserves the right to have a rider to the entry premises inventory drawn up at the exclusive expense of the Lessee. 

At the end of the lease, for all changes, embellishments and modifications of any kind, the Lessor shall have the option of keeping them, without
compensation, in their current state, or to require their removal and the restoration of the premises, partially or fully, to their initial condition, at the Lessee’s expense, where these works were carried out with the express agreement of the
Lessor, unless the parties agree otherwise in writing and by means of a rider to the premises inventory in accordance with the terms described in the previous paragraph. The same shall apply for all lighting, entry doorbells, computer wiring,
partitions, acoustic barriers, etc. installed by the Lessee. 
 If the Lessor authorizes the maintenance of a technical, electrical or electronic
installation, it reserves the right at the end of the lease to have a compliance check of said installation carried out by a control company at the Lessee’s expense, provided that the Lessee has not communicated a copy of such a compliance
check to the Lessor.

 Article 14: Work, repairs and maintenance 

Only major repairs as listed in the Belgian Civil Code are the responsibility of the Lessor, provided that they are not attributable to the Lessee, all other
repairs are the responsibility of the Lessee. 
 The Lessee is required to maintain the leased premises, at its own expense, in a good state of repair. In
particular, it has the premises and the interior surfaces of the windows cleaned, so that they are in a constant state of cleanliness. 
 If abnormal damage
should occur, and if the Lessor demonstrates that the responsibility for this abnormal damage is attributable to the Lessee, the latter may require the Lessee, by registered letter, to carry out all repair work and to complete this within two months
of this registered letter being sent. Failing this, the Lessor is then authorized to have all work performed at the expense, risk and peril of the defaulting Lessee. 

The Lessee shall tolerate access to the leased premises to the Lessor, its staff, and the professionals designated by the Lessor, after it has been notified,
for the purpose of verifying the condition of the leased premises and the building in general and carrying out the necessary inspections and repairs even when these repairs concern a neighboring tenant, it being understood that these works will be
carried out with normal care. 
 The Lessee shall immediately notify the Lessor by registered letter of the need for any repairs incumbent upon it, under
penalty of being held liable for any damage resulting therefrom and for any harmful consequences, for which the Lessor cannot be held liable in the absence of such notice. 

The Lessor undertakes, on the other hand, to take the necessary measures no later than two months after the registered letter referred to in the previous
paragraph. 
 In the event that the repairs would be covered by the insurers of the building, the Lessee shall intervene up to the amount of the excess,
provided that the loss is incumbent upon it or is attributable to it, and the difference between the insurance compensation and the price actually paid. 

The Lessee shall immediately replace, at its own expense, all broken, cracked or damaged windows, except in the event of fault or omission or negligence
attributable to the Lessor or its agents and agents or, in accordance with Article 1754 of the Civil Code, as a result of hailstones, or other extraordinary accidents and force majeure. 

Article 15: Change of requirements 
 The Axisparc
complex complies with the legal and regulatory requirements in force on the date of the town planning permit. 
 The works imposed by administrative
provisions resulting from the Lessee’s activity will be at its own expense, without it being able to claim reimbursement from the Lessor upon its departure, or claim the dissolution of the lease for any reason whatsoever. They fall under the
application of Article 13 of this lease. 

  
 9 

 Article 16: Guarantee 

To guarantee the performance of all the obligations incumbent upon it under this lease, the Lessee shall take out for the benefit of the Lessor an irrevocable
guarantee which will be callable upon at the first request from a bank approved by the Lessor and of a value equal to one semester of rent, i.e. €46,100. The Lessor will call upon this guarantee insofar that it can demonstrate a serious breach
by the Lessee of the obligations arising from this lease and provide evidence demonstrating the reality of the amount claimed. The Lessor will be given the text of the guarantee 15 days before the start of the lease in order to make its comments.
The guarantee shall take effect at the beginning of this lease. 
 The establishment of the rental guarantee constitutes an essential condition without
which the Lessor would not have entered into the contract. Any breach of such an obligation shall be deemed serious, which fact the Lessee expressly declares to accept. 

In the event of readjustment of the rent, the amount of the guarantee will be adjusted at the same time so as to always represent a sum corresponding to one
half-year of the rent. 
 The bank guarantee will be issued before occupancy of the leased premises. 

In any event, said text must stipulate that the guarantee is constituted for a period expiring no earlier than three months after the expiry of the lease.

 This guarantee will be returned to the Lessee three months after the end of the lease, unless the Lessor demonstrates that the Lessee has not fully
fulfilled its obligations under this lease agreement. During the term of the lease, the guarantee may in no case be offered or allocated, in whole or in part, by the Lessee as payment of the rent or other contractual debts. 

In the event of bankruptcy of the Lessee, the guarantee may be used by the Lessor to offset the arrears of payment and other breaches by the Lessee of its
obligations, including rents and communal charges. 
 In the absence of this guarantee, and in accordance with Article 1752 of the Belgian Civil Code, the
Lessee shall remain obliged to keep the leased premises furnished with furniture of sufficient value to guarantee a minimum of 6 months’ rent. 

Article 17: Assignment and subletting 
 The Lessee
may not assign this lease or sublet the premises, in whole or in part, without the express, prior written consent of the Lessor, it being understood that the latter may refuse the assignment of the lease or the planned sublease for just cause. 

In the event that the Lessor authorizes the assignment or sublease of the premises, in whole or in part, the Lessee, the
sub-lessee, the assignor and the assignee will be bound jointly and severally with regard to the Lessor, to all the obligations arising from this lease and the
co-ownership regulations, the Lessee undertakes to obtain from the sub-lessee or the assignee that which it expressly subscribes in terms of obligations to the Lessor.
Failing this, the assignment or subletting may not take place, even if the Lessor had given its prior written consent, unless at that time it had expressly waived the requirement of such commitment. 

The term of the sublease may not in any case exceed the term of this lease. 

As soon as the transfer or sublease is concluded, and as long as it is authorized, the Lessee shall send the Lessor a registered copy of the agreement
reached.

 Article 18: Waiver of recourse - Insurance 

 

	A.	 Waiver of recourse 

 

	1.	 The Lessee declares that it waives all recourse against the Lessor due to inconveniences and material and
immaterial damage, the occurrence of which is related to its express occupation of the building, provided that these are not related to repairs that would have been made by the Lessor in accordance with Article 1720, paragraph 2, of the Belgian
Civil Code. This includes accidental deterioration and interruptions that may occur in the water, gas, electricity, heating, doorbell system or any other technical installations serving the building. 

This waiver of recourse benefits both the Lessor and the companies of its group, and their employees. 

 

	2.	 The Lessee undertakes to have its sub-tenants, plus their occupants and
staff, make the same declaration in writing to the Lessor. In all cases, it is held personally liable for any recourse that these persons may bring against the Lessor or the other persons whom the waiver of recourse should have benefited.

  

	3.	 In return, the Lessor waives any recourse that it may exercise during the lease against the Lessee, the sub-tenants, occupants and staff thereof, on the grounds of the damage covered by the fire policy described in point B 1 below. 

This waiver of recourse benefits both the Lessee and the companies of its group, and their employees. 

 

	4.	 However, the aforementioned waivers of recourse remain of no effect when the persons called upon to benefit
from them under normal conditions have intentionally caused the damage. 

  

	B.	 Insurance policies 

 

	1.	 The Lessor shall take out a policy covering the leased property, through the
co-ownership of the building, and shall maintain this in force throughout the term of the lease. This policy will provide for the waiver of recourse referred to in point A.3. of this Article; it will at all
times provide the most extensive coverage that the Lessor will deem prudent to take, and in all cases, damage due to strikes and riots: it will also provide that the Lessee is covered as insured party for bodily damage other than caused to third
parties by fire, explosion and water damage, when the incident is primarily due to the leased property. 

  

	2.	 The Lessee shall take out an insurance policy covering the contents located in the leased property, within one
month of receiving the keys, provided for in Article 26 of this lease and shall maintain this in force throughout the term of the lease. This policy will lead to the waiver of recourse referred to in point A.1. of this article.

  

	3.	 The Lessor and the Lessee may at any time request proof of the existence of the policies in question in points
1 and 2 above and the coverage they grant. 

  

	4.	 The Lessee will contribute to the insurance costs according to the indications in Article 7 of this lease. If a
claim is attributable to it, the deductible will be personally charged to it at the time of the next quarterly statement of charges. 

  
 11 

	5.	 In the event that the Lessee’s activities and those for which it is responsible should result in an
increase in the insurance premiums owed by the Lessor and by other tenants of the building, this increase will exclusively be the Lessee’s responsibility. 

Article 19: Exemption from liability of the Lessor and its beneficiaries 

The Lessee must assume the security and effective protection of the premises it leases; it expressly exempts the Lessor and its beneficiaries from any
liability in the event of theft occurring in the leased premises. 
 In the event that administrative or judicial proceedings are initiated against the
Lessor, due to the activity or presence of the Lessee in the leased premises, the Lessee undertakes to take up the cause for the Lessor, and to bear any resulting conviction. 

Article 20: Collective liquidation procedure 
 In
the event of winding up, bankruptcy or liquidation of the Lessee, the Lessor has the right, if it so wishes, to terminate the lease agreement, without notice. The Lessee is obliged to inform the Lessor of any winding up or bankruptcy, or
liquidation. The Lessor shall notify its decision by registered letter sent by mail within three months of the event justifying the termination being reported. 

Article 21: Judicial termination 
 In the event of
a judicial termination of this lease due to the fault of the Lessee, the latter shall be liable for a relocation indemnity left to the discretion of the judge, without prejudice to the application of all the Articles of this lease, in addition to
all other costs that the Lessor would be entitled to claim from the Lessee, without prejudice to the application of Article 12 above. 
 This provision may
not under any circumstances be invoked by the Lessee to release itself from the obligations resulting for it from this lease. 
 The Lessee acknowledges
having been notified and having accepted that any breach of the obligations contained in Articles 3, 5, 7, 8, 13, 16, 17 and 18 is considered sufficiently serious only to justify that the Lessor can initiate proceedings to decide on the termination
of the lease due to its fault. 
 Article 22: Expropriation 

In the event of expropriation due to public utility cause, the lease will end on the date on which the expropriating public, private or general interest
authority becomes the owner of the premises. 
 Under no circumstances may the compensation to which the Lessee would be entitled to require from the
expropriating authority reduce the amount of the compensation due to the Lessor. The Lessee may not claim any compensation from the Lessor and must assert its rights with the expropriating authority in separate proceedings. 

  
 12 

 The Lessor shall inform the Lessee as soon as possible of any expropriation procedure and its evolution. In the
event of expropriation, the Lessee is not required to restore the leased premises to their rental condition, as stipulated in Article 12. 
 Article
23: Visit to the premises 
 The Lessee shall at all times be required to give access to the leased premises to the Lessor and its staff, after it

Article
1

DESCRIPTION OF TRANSACTION

 

Section 1.1
Structure of the Merger. Upon the terms and subject to the conditions set forth in this Agreement and in accordance
with the DGCL, at the Effective Time, (a) Merger Sub shall be merged with and into Quoin, and (b) the separate existence of Merger
Sub shall cease and Quoin will continue its corporate existence under the DGCL as the surviving corporation in the Merger (the

and subject to the satisfaction or waiver of the conditions set forth in Article 6, Article 7 and Article 8,
the closing of the Merger (the “Closing”) shall take place remotely by electronic transfer of documentation
as promptly as practicable (but in no event later than the second Business Day following the satisfaction or waiver of the last
to be satisfied or waived of the conditions set forth in Article 6, Article 7 and Article 8, other than those
conditions that by their nature are to be satisfied at the Closing, but subject to the satisfaction or waiver of each of such conditions),

    2

     

    

 

Section 1.4
Certificate of Incorporation and Bylaws; Directors and Officers. At the Effective Time:

 

(a)
the certificate of incorporation of the Surviving Corporation shall be amended and restated in its entirety to read identically
to the certificate of incorporation of Merger Sub as in effect immediately prior to the Effective Time, until thereafter amended
in accordance with the terms of such certificate of incorporation, the certificate of incorporation of the Surviving Corporation
and the DGCL;

 

(b)
the Articles of Association of Cellect shall be the Articles of Association of Cellect immediately prior to the Effective
Time, until thereafter amended as provided by the Companies Law and such Articles of Association; provided, however,
that immediately prior to the Effective Time, Cellect shall effect one or more amendments to its Articles of Association, to the
extent approved by the holders of Cellect Ordinary Shares as contemplated by Section 5.3, to (i) change the name of Cellect
to “QUOIN PHARMACEUTICALS, LTD.” or a similar name agreed between the Parties and approved by the Israeli Companies
Registrar (ii) increase the authorized Cellect Ordinary Shares, to the extent requested by Quoin prior to the filing with the SEC
of the Proxy Statement, and (iii) make such other changes as are mutually agreeable to Cellect and Quoin;

 

(c)
the bylaws of the Surviving Corporation shall be amended and restated in their entirety to read identically to the bylaws
of Merger Sub as in effect immediately prior to the Effective Time, until thereafter amended in accordance with the terms of such
bylaws, the certificate of incorporation of the Surviving Corporation and the DGCL; and

 

(d)
the directors and officers of the Surviving Corporation and the directors and officers of Cellect shall be the directors
and officers set forth in Schedule 5.11 or as otherwise determined by Quoin with respect to the directors and officers of
the Surviving Corporation or as otherwise determined by Quoin and Cellect in accordance with Schedule 5.11 with respect
to the directors and officers of Cellect.

 

Section 1.5
Conversion of Quoin Securities.

 

(a)
At the Effective Time, by virtue of the Merger and without any further action on the part of Cellect, Merger Sub, Quoin
or any Quoin Stockholder:

 

(i)
each share of Quoin Common Stock held as treasury stock or held or owned by Quoin, Cellect, any Cellect Subsidiary or Merger
Sub, immediately prior to the Effective Time shall be canceled and retired and shall cease to exist, and no consideration shall
be delivered in exchange therefor; and

 

    3

     

    

 

(ii)
Subject to Section 1.5(a)(iii), each share of Quoin Common Stock outstanding immediately prior to the Effective Time
(including any shares of Quoin Common Stock issued pursuant to the Quoin Financing and including, for the avoidance of doubt, the
Additional Quoin Shares outstanding immediately prior to the Effective Time, but excluding shares to be canceled pursuant to Section
1.5(a)(i) and Dissenting Shares) shall be converted solely into the right to receive a number of Cellect Ordinary Shares equal
to the Exchange Ratio which will trade in the United States in the form of American Depositary Shares (“ADSs,”
each ADS currently representing 100 Ordinary Share), evidenced by American Depositary Receipts (“ADRs”)
(such ADSs, together with any cash in lieu of fractional ADSs, the “Merger Consideration”).

 

(iii)
No fractional ADRs will be issued and any holder of shares of Quoin Common Stock entitled to receive a fractional ADRs but
for this Section 1.5(a)(iii) shall be entitled to receive a cash payment in lieu thereof, which payment shall represent
such holder’s proportionate interest in the net proceeds for the sale by the Exchange Agent on behalf of such holder of the
aggregate fractional ADRs that such holder otherwise would be entitled to receive. Any such sale shall be made by the Exchange
Agent within five (5) Business Days after the date upon which the certificate (or affidavit(s) of loss in lieu thereof) that would
otherwise result in the issuance of such fractional ADSs has been received by the Exchange Agent.

 

(iv)
Each share of common stock, $0.01 par value per share, of Merger Sub issued and outstanding immediately prior to the Effective
Time shall be converted into and exchanged for one validly issued, fully paid and nonassessable share of common stock, $0.01 par
value per share, of the Surviving Corporation. Each stock certificate of Merger Sub evidencing ownership of any such shares shall,
as of the Effective Time, evidence ownership of such shares of common stock of the Surviving Corporation.

 

(b)
If, between the time of calculating the Exchange Ratio and the Effective Time, the outstanding (i) shares of Quoin Common
Stock or (ii) Cellect Ordinary Shares have been changed into, or exchanged for, a different number of shares or a different class,
by reason of any stock dividend, subdivision, reclassification, recapitalization, split (including the ADR Ratio Adjustment to
the extent such split has not been previously taken into account in calculating the Exchange Ratio), combination or exchange of
shares, the Exchange Ratio shall be correspondingly adjusted to provide the holders of Quoin Common Stock the same economic effect
as contemplated by this Agreement prior to such event.

 

Section 1.6
Closing of Quoin’s Transfer Books. At the Effective Time: (a) all shares of Quoin Common Stock outstanding
immediately prior to the Effective Time shall be treated in accordance with Section 1.5, and (i) all holders of certificates
representing shares of Quoin Capital Stock that were outstanding or (ii) holders of shares of Quoin Capital Stock that were deemed
issued immediately prior to the Effective Time shall cease to have any rights as stockholders of Quoin; and (b) the stock transfer
books of Quoin shall be closed with respect to all shares of Quoin Capital Stock outstanding immediately prior to the Effective
Time. No further transfer of any such shares of Quoin Capital Stock shall be made on such stock transfer books after the Effective
Time. If, after the Effective Time, a valid certificate previously representing any shares of Quoin Capital Stock outstanding immediately
prior to the Effective Time (a “Quoin Stock Certificate”) is presented to the Exchange Agent or to the
Surviving Corporation, such Quoin Stock Certificate shall be canceled and shall be exchanged as provided in Section 1.5
and Section 1.7.

 

    4

     

    

 

Section 1.7
Exchange of Securities.

 

(a)
Prior to the Effective Time, Cellect shall designate Bank of New York Mellon, which currently acts as the depository for
the ADSs, or another U.S. bank or trust company reasonably acceptable to Quoin (in such capacity, the “Depository”),
to act as agent in the Merger (the “Exchange Agent”). At or prior to the Effective Time, Cellect shall
deposit or cause the Depository to deposit with the Exchange Agent, (i) that number of ADRs and (ii) cash, in each case as are
issuable or payable, respectively, pursuant to this Article 1 in respect of Quoin Capital Stock. The deposit made by Cellect
or Merger Sub, as the case may be, pursuant to this Section 1.7 is hereinafter referred to as the “Exchange
Fund.”

 

(b)
Promptly after the Effective Time, the Parties shall cause the Exchange Agent to mail to the Persons who were record holders
of Quoin Capital Stock immediately prior to the Effective Time: (i) a letter of transmittal in customary form; and (ii) instructions
for effecting the surrender of Quoin Stock Certificates in exchange for book-entry ADRs. Upon surrender of the Quoin Capital Stock
to the Exchange Agent for exchange, together with a duly executed letter of transmittal and such other documents as may be reasonably
required by the Exchange Agent: (A) the holder of such Quoin Capital Stock shall be entitled to receive in exchange therefor one
or more restricted book-entry ADRs representing the portion of the Merger Consideration (in a number of whole ADRs) that such holder
has the right to receive pursuant to the provisions of Section 1.5 (and cash in lieu of any fractional share of ADRs pursuant
to the provisions of Section 1.5(a)(iii)); and (B) if applicable, upon delivery of such consideration to the applicable
holder in accordance with Section 1.5, the Quoin Stock Certificate so surrendered shall be canceled. Until surrendered as
contemplated by this Section 1.7(b), each share of Quoin Capital Stock shall be deemed, from and after the Effective Time,
to represent only the right to receive ADRs (and cash in lieu of any fractional share of ADRs). If any Quoin Stock Certificate
has been lost, stolen or destroyed, Cellect may, in its discretion and as a condition precedent to the delivery of any restricted
ADRs, require the owner of such lost, stolen or destroyed Quoin Stock Certificate to provide an applicable affidavit with respect
to such Quoin Stock Certificate and post a bond indemnifying Cellect against any claim suffered by Cellect related to the lost,
stolen or destroyed Quoin Stock Certificate or any restricted ADRs issued in exchange therefor as Cellect may reasonably request.
Promptly after the Effective Time, the Parties shall cause the Exchange Agent to mail to the Persons who were holders of the Bridge
Warrants immediately prior to the Effective Time instructions for exchanging the Bridge Warrants for Exchange Warrants.

 

(c)
No dividends or other distributions declared or made with respect to Cellect Ordinary Shares with a record date after the
Effective Time shall be paid to the holder of any unsurrendered Quoin Stock Certificate with respect to the ADRs that such holder
has the right to receive in the Merger until such holder surrenders such Quoin Stock Certificate or an affidavit of loss or destruction
in lieu thereof in accordance with this Section 1.7 (at which time such holder shall be entitled, subject to the effect
of applicable abandoned property, escheat or similar laws, to receive all such dividends and distributions, without interest).

 

    5

     

    

 

(d)
Any portion of the Exchange Fund that remains undistributed to holders of Quoin Capital Stock six months after the Closing
Date shall be delivered to Cellect upon demand, and any holders of Quoin Capital Stock who have not theretofore surrendered their
Quoin Stock Certificates (if applicable) and/or delivered a letter of transmittal in accordance with this Section 1.7 shall
thereafter look only to Cellect for satisfaction of their claims for ADRs, cash in lieu of fractional ADRs and any dividends or
distributions with respect to ADRs.

 

(e)
Each of the Exchange Agent, Cellect, Merger Sub, the Surviving Corporation and their respective agents shall be entitled
to deduct and withhold from any consideration deliverable pursuant to this Agreement to any holder of any Quoin Stock Certificate
such amounts as are required to be deducted or withheld from such consideration if such withholding is required under any applicable
Israeli or U.S. Tax laws. To the extent such amounts are so deducted or withheld, and remitted to the appropriate Tax authority,
such amounts shall be treated for all purposes under this Agreement as having been paid to the Person to whom such amounts would
otherwise have been paid; notwithstanding the foregoing, the Exchange Agent, Cellect, Merger Sub, the Surviving Corporation and
their respective agents shall not withhold any such Tax (or shall withhold at a reduced rate) with respect to any holder of Quoin
Capital Stock or Quoin Warrants if such holder delivers to the Exchange Agent, Cellect, Merger Sub, the Surviving Corporation or
their applicable agents, together with the exchanged Quoin Stock Certificate or Quoin Warrants a validly executed IRS Form W-9
or appropriate IRS Form W-8, as applicable, including supporting documentation to the extent required, indicating a valid exemption
from or qualification for a reduced rate of U.S. Tax withholding, and a validly executed declaration of non-Israeli residence in
the form attached hereto as Exhibit D.

 

Section 1.8
Appraisal Rights.

 

(a)
Notwithstanding any other provision of this Agreement to the contrary, shares of Quoin Capital Stock held by a holder who
has made a demand for appraisal of such shares in accordance with Section 262 of the DGCL (any such shares being referred to as
“Dissenting Shares” until such time as such holder fails to perfect or otherwise loses such holder’s
appraisal rights under Section 262 of the DGCL with respect to such shares), will not be converted into or represent the right
to receive ADRs in accordance with Section 1.5, but will be converted into the right to receive such consideration as may
be determined to be due with respect to such Dissenting Shares pursuant to the DGCL (and at the Effective Time, such Dissenting
Shares shall no longer be outstanding and shall automatically be cancelled and shall cease to exist), and such holder shall cease
to have any rights with respect thereto, except the rights set forth in Section 262 of the DGCL; provided, however, that
if a holder of Dissenting Shares (a “Dissenting Stockholder”) withdraws, has failed to perfect or otherwise
loses such holder’s demand for such payment and appraisal or becomes ineligible for such payment and appraisal then, as of

filed and no current or former principal executive officer or principal financial officer of Cellect has failed to make the Certifications
required of him or her. As used in this Article 3, the term “file” and variations thereof shall be broadly construed
to include any manner in which a document or information is furnished, supplied or otherwise made available to the SEC. Cellect
has made available to Quoin true and complete copies of all correspondence, other than transmittal correspondence, between the
SEC, on the one hand, and Cellect, on the other, since January 1, 2015, including all SEC comment letter and responses to such
comment letters and responses to such comment letters by or on behalf of Cellect other than such documents that can be obtained
on the SEC’s website at www.sec.gov. As of the date of this Agreement, there are no outstanding or unresolved comments in
comment letters received from the SEC or NASDAQ with respect to Cellect SEC Documents. To the Knowledge of Cellect, none of Cellect
SEC Documents are the subject of ongoing SEC review and there are no inquiries or investigations by the SEC or any internal investigations
pending or threatened, including with regards to any accounting practices of Cellect.

 

(b)
The financial statements (including any related notes) contained or incorporated by reference in the Cellect SEC Documents:
(i) complied as to form in all material respects with the published rules and regulations of the SEC applicable thereto; (ii)
were prepared in accordance with IFRS (except as may be indicated in the notes to such financial statements or, in the case of
unaudited financial statements, as permitted by Item 8.A.5 of Form 20-F of the SEC, and except that the unaudited financial statements
may not contain footnotes and are subject to normal and recurring year-end adjustments that are not reasonably expected to be
material in amount) applied on a consistent basis unless otherwise noted therein throughout the periods indicated; and (iii) fairly
present the consolidated financial position of Cellect and any Cellect Subsidiary as of the respective dates thereof and the results
of operations and cash flows of Cellect for the periods covered thereby, subject to any exemptions or reliefs afforded to a reporting
company that qualifies as a foreign private issuer or an emerging growth company. Other than as expressly disclosed in the Cellect
SEC Documents filed prior to the date hereof, there has been no material change in Cellect’s accounting methods or principles
that would be required to be disclosed in Cellect’s financial statements in accordance with GAAP. The books of account and
other financial records of Cellect and any Cellect Subsidiary are true and complete in all material respects.

(c)
Cellect’s auditor has at all times since its retention by Cellect been: (i) to the Knowledge of Cellect, a registered
public accounting firm (as defined in Section 2(a)(12) of the Sarbanes-Oxley Act); (ii) to the Knowledge of Cellect, “independent”
with respect to Cellect within the meaning of Regulation S-X under the Exchange Act; and (iii) to the Knowledge of Cellect, in
compliance with subsections (g) through (l) of Section 10A of the Exchange Act and the rules and regulations promulgated by the
SEC and the Public Company Accounting Oversight Board thereunder with respect to services provided to Cellect.

 

(d)
Except as set forth in Section 3.5(d) of the Cellect Disclosure Schedule, from January 1, 2016 through the date hereof,
Cellect has not received any correspondence from NASDAQ or the staff thereof relating to the delisting or maintenance of listing
of the Cellect Ordinary Shares on The NASDAQ Capital Market.

 

(e)
Since January 1, 2016, there have been no formal internal investigations regarding financial reporting or accounting policies
and practices discussed with, reviewed by or initiated at the direction of the chief executive officer or chief financial officer
of Cellect, the Cellect Board of Directors or any committee thereof, other than ordinary course audits or reviews of accounting
policies and practices or internal controls required by the Sarbanes-Oxley Act.

 

(f)
Cellect is in compliance in all material respects with the applicable provisions of the Sarbanes-Oxley Act and the applicable
listing and governance rules and regulations of The NASDAQ Capital Market and the Companies Law.

 

(g)
Cellect maintains a system of internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) of
the Exchange Act) that is sufficient to provide reasonable assurance regarding the reliability of financial reporting and the preparation
of financial statements for external purposes in accordance with GAAP, including policies and procedures sufficient to provide
reasonable assurance (i) that Cellect maintains records that in reasonable detail accurately and fairly reflect Cellect’s
transactions and dispositions of assets, (ii) that transactions are recorded as necessary to permit preparation of financial statements
in accordance with GAAP, (iii) that receipts and expenditures are made only in accordance with authorizations of management and
the Cellect Board of Directors, and (iv) regarding prevention or timely detection of the unauthorized acquisition, use or disposition
of Cellect’s assets that could have a material effect on Cellect’s financial statements. Cellect has evaluated the
effectiveness of Cellect’s internal control over financial reporting and, to the extent required by applicable Legal Requirements,
presented in any applicable Cellect SEC Document that is a report on Form 20-F (or any amendment thereto) its conclusions about
the effectiveness of the internal control over financial reporting as of the end of the period covered by such report or amendment
based on such evaluation. Cellect has disclosed to Cellect’s auditors and the audit committee of the Cellect Board of Directors
(and made available to Quoin a summary of the significant aspects of such disclosure) (A) all significant deficiencies and material
weaknesses in the design or operation of internal control over financial reporting that are reasonably likely to adversely affect
Cellect’s ability to record, process, summarize and report financial information and (B) any fraud, whether or not material,
that involves management or other employees who have a significant role in Cellect’s internal control over financial reporting.
Except as disclosed in the Cellect SEC Documents filed prior to the date hereof, Cellect has not identified any material weaknesses
in the design or operation of Cellect’s internal control over financial reporting. Since January 1, 2016, there have been
no material changes in Cellect’s internal control over financial reporting.

 

    36

     

    

 

(h)
Cellect’s “disclosure controls and procedures” (as defined in Rules 13a-15(e) and 15d-15(e) of the Exchange
Act) are reasonably designed to ensure that all information (both financial and non-financial) required to be disclosed by Cellect
in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time
periods specified in the rules and forms of the SEC, and that all such information is accumulated and communicated to Cellect’s
management as appropriate to allow timely decisions regarding required disclosure and to make the Certifications.

 

Section 3.6
Absence of Changes. Except as set forth in Section 3.6 of the Cellect Disclosure Schedule, between September
30, 2020 and the date of this Agreement, each of Cellect and any Cellect Subsidiary have conducted its business in the Ordinary
Course of Business and there has not been (a) any event that has had a Cellect Material Adverse Effect or (b) or any action, event
or occurrence that would have required consent of Quoin pursuant to Section 4.2(b) of this Agreement had such action, event
or occurrence taken place after the execution and delivery of this Agreement.

 

Section 3.7
Title to Assets. Except with respect to material Cellect IP Rights, which are covered in Section 3.9, each
of Cellect and any Cellect Subsidiary owns, and has good and valid title to, or, in the case of leased properties and assets, valid
leasehold interests in, all tangible properties or assets and equipment used or held for use in its business or operations or purported
to be owned by it, in each case, free and clear of any Encumbrances, except for: (i) any lien for current Taxes not yet due and
payable or for Taxes that are being contested in good faith and for which adequate reserves have been made on the Cellect Unaudited
Interim Balance Sheet; (ii) minor liens that have arisen in the Ordinary Course of Business and that do not (in any case or in
the aggregate) materially detract from the value of the assets subject thereto or materially impair the operations of Cellect or
any Cellect Subsidiary; and (iii) liens listed in Section 3.7 of the Cellect Disclosure Schedule.

 

Section 3.8
Real Property; Leaseholds. Neither Cellect nor any Cellect Subsidiary currently owns or has ever owned any real property
or any interest in real property, except for the leaseholds created under the real property leases (including any amendments thereto)
identified in Section 3.8 of the Cellect Disclosure Schedule (the “Cellect Leases”), which are
each in full force and effective, with no existing material default thereunder.

 

    37

     

    

 

Section 3.9
Intellectual Property.

 

(a)
Cellect, directly or through any of its Subsidiaries, owns, or has the right to use all Cellect IP Rights, except for any
failure to own or have the right to use that would not constitute a Cellect Material Adverse Effect. The foregoing representation
and warranty is not intended to be a representation regarding the absence of infringement or misappropriation, which is addressed
in Section 3.9(g) below.

 

(b)
Section 3.9(b) of the Cellect Disclosure Schedule is an accurate, true and complete listing of (i) all patents within
the Cellect Registered IP that are owned by Cellect and (ii) all other Cellect Registered IP.

 

(c)
Section 3.9(c) of the Cellect Disclosure Schedule accurately identifies (i) all Cellect IP Rights licensed to Cellect
or any Cellect Subsidiary (other than (A) any non-customized software that (1) is so licensed solely in executable or object code
form pursuant to a non-exclusive, internal use software license and other Intellectual Property associated with such software and
(2) is not incorporated into, or material to the development, manufacturing, or distribution of, any of Cellect’s or any
of its Subsidiaries’ products or services, (B) any Intellectual Property licensed ancillary to the purchase or use of equipment,
reagents or other materials, (C) non-disclosure agreements, materials transfer agreements and template agreements entered into
in the Ordinary Course of Business and (D) agreements between Cellect and its employees and consultants); (ii) the corresponding
Cellect Contracts pursuant to which such Cellect IP Rights are licensed to Cellect or any Cellect Subsidiary; (iii) whether the
license or licenses granted to Cellect or any Cellect Subsidiary are exclusive or non-exclusive; and (iv) whether, to the Knowledge
of Cellect or its Subsidiaries, any funding, facilities or personnel of any Governmental Body were used, directly or indirectly,
to develop or create, in whole or in part, such Cellect IP Rights.

 

(d)
Section 3.9(d) of the Cellect Disclosure Schedule accurately identifies each Cellect Contract pursuant to which any
Person (other than Cellect or any Cellect Subsidiary) has been granted any license or option to obtain a license under, or otherwise
has received or acquired any right (whether or not currently exercisable) or interest in, any Cellect IP Rights (in each case,
other than non-disclosure agreements, materials transfer agreements or non-exclusive licenses entered into in the Ordinary Course
of Business). Cellect is not bound by, and no Cellect IP Rights (and to the Knowledge of Cellect, no licensed Cellect IP Rights)
are subject to, any Contract containing any covenant or other contractual obligation that in any way limits or restricts the ability
of Cellect or any Cellect Subsidiary to use, exploit, assert or enforce any Cellect IP Rights anywhere in the world, in each case
as would materially limit the business of Cellect as currently conducted or planned to be conducted.

 

(e)
Except as identified on Section 3.9(e) of the Cellect Disclosure Schedule, Cellect or one of its Subsidiaries solely
owns all right, title, and interest to and in the Cellect Registered IP listed on (or required to be listed on) Section 3.9(b)
of the Cellect Disclosure Schedule free and clear of any Encumbrances. Without limiting the generality of the foregoing:

 

(i)
All documents and instruments necessary to register or apply for or renew registration of all Cellect Registered IP that
is solely owned by Cellect or one of its Subsidiaries have been validly executed, delivered and filed in a timely manner with the
appropriate Governmental Body except for any such failure, individually or collectively, that would not constitute a Cellect Material
Adverse Effect.

 

    38

     

    

 

(ii)
Each Person who is or was an employee or contractor of Cellect or any Cellect Subsidiary and who is or was involved in the
creation or development of any Cellect IP Rights has signed a written agreement containing an assignment of such Intellectual Property
to Cellect or such Subsidiary and confidentiality provisions protecting trade secrets and confidential information of Cellect and
its Subsidiaries; provided, that any such agreement with a third party contractor for research, development or manufacturing
services on behalf of Cellect or any Cellect Subsidiary may provide that such third party contractor reserves its rights in improvements
to such third party contractor’s Intellectual Property or generally applicable research, development or manufacturing technology,
in either case that is not specific to any product or service of Cellect or any Cellect Subsidiary. To the Knowledge of Cellect
and its Subsidiaries, no current or former stockholder, officer, director, employee or contractor of Cellect or any Cellect Subsidiary
has any claim, right (whether or not currently exercisable), or interest to or in any Cellect IP Rights. To the Knowledge of Cellect
and its Subsidiaries, no employee or contractor of Cellect or any or any of its Subsidiaries is (a) bound by or otherwise subject
to any Contract restricting him or her from performing his or her duties for Cellect or such Subsidiary or (b) in breach of any
Contract with any current or former employer or other Person concerning Cellect IP Rights or confidentiality provisions protecting
trade secrets and confidential information comprising Cellect IP Rights.

 

(iii)
No funding, facilities or personnel of any Governmental Body were used, directly or indirectly, to develop or create, in
whole or in part, any Cellect IP Rights in which Cellect or any Cellect Subsidiary has an ownership interest.

 

(iv)
Cellect and each of its Subsidiaries has taken reasonable steps to maintain the confidentiality of and otherwise protect
and enforce its rights in all proprietary information that Cellect or such Subsidiary holds, or purports to hold, as a trade secret.

 

(v)
Except for the contemplated sale of Cellect Biotherapeutics or as set forth on Section 3.9(e)(v) of the Cellect Disclosure
Schedule, neither Cellect nor any Cellect Subsidiary has assigned or otherwise transferred ownership of, or agreed to assign or
otherwise transfer ownership of, any Cellect IP Rights to any other Person.

 

(vi)
The Cellect IP Rights constitute all Intellectual Property necessary for Cellect and its Subsidiaries to conduct its business
as currently conducted or planned to be conducted.

 

(f)
The manufacture, marketing, license, sale or intended use of any product or service currently approved or sold or under
preclinical or clinical development by Cellect or any Cellect Subsidiary (i) does not violate or constitute a breach of any license
or agreement between Cellect or its Subsidiaries and any third party, and, (ii) to the Knowledge of Cellect and its Subsidiaries,
does not infringe or misappropriate any Intellectual Property right of any third party. To the Knowledge of Cellect and its Subsidiaries,
no third party is infringing upon or misappropriating, or violating any license or agreement with Cellect or its Subsidiaries relating
to, any Cellect IP Rights. There is no current or, to the Knowledge of Cellect, pending challenge, claim or Legal Proceeding (including
opposition, interference or other proceeding in any patent or other government office) contesting the validity, enforceability,
ownership or right to use, sell, license or dispose of any Cellect IP Rights, nor has Cellect or any Cellect Subsidiary received
any written notice asserting that the manufacture, marketing, license, sale or intended use of any product or service currently
approved or sold or under preclinical or clinical development by Cellect or any Cellect Subsidiary infringes or misappropriates
or will infringe or misappropriate the rights of any other Person.

 

    39

     

    

 

(g)
Each item of Cellect IP Rights that is Cellect Registered IP that is solely owned by Cellect or one of its Subsidiaries
is and at all times has been filed and maintained in compliance with all applicable Legal Requirements and all filings, payments
and other actions required to be made or taken to maintain such item of Cellect Registered IP in full force and effect have been
made by the applicable deadline, except for any failure to perform any of the foregoing, individually or collectively, that would
not constitute a Cellect Material Adverse Effect.

 

(h)
No trademark (whether registered or unregistered) or trade name owned, used, or applied for by Cellect or any Cellect Subsidiary
conflicts or interferes with any trademark (whether registered or unregistered) or trade name owned, used, or applied for by any
other Person. None of the goodwill associated with or inherent in any trademark (whether registered or unregistered) in which Cellect
or any Cellect Subsidiary has or purports to have an ownership interest has been impaired as determined by Cellect or any Cellect
Subsidiary in accordance with GAAP.

 

(i)
Cellect and all Cellect Subsidiaries have complied in all material respects with (i) all of their respective stated privacy
policies, programs and other similar notices and (ii) all data protection, privacy and other applicable Legal Requirements (including
Israel’s Protection of Privacy Law (1981) and related regulations) that concern the collection, retention, storage, recording,
processing, transfer, sharing or other disposition or use of any personally identifiable information and “information,”
as defined by Israeli laws and applicable Israeli judicial precedent (“Israeli Personal Information”),
and there have not been any incidents of data security breaches, including any breaches of software, hardware, databases, computer
equipment or other information technology. To the Knowledge of Cellect, there is no complaint to, or any audit, proceeding, investigation
(formal or informal) or claim currently pending against Cellect or a Cellect Subsidiary by any private party or any Governmental
Body, foreign or domestic, with respect to Israeli Personal Information. With respect to all Israeli Personal Information collected,
stored, used, or maintained by or for Cellect or any Cellect Subsidiary, Cellect and any Cellect Subsidiary have at all times implemented
reasonable security measures to ensure that such Israeli Personal Information is protected against loss and against unauthorized
access, use, modification, and disclosure.

 

(j)
All databases, data compilations, and any collection deemed a database or regulated collection of data under applicable
laws that are owned, controlled, held or used by Cellect and by any Cellect Subsidiary and that are required to be registered have
been properly registered, and the data therein has been used by Cellect or any Cellect Subsidiary solely as permitted pursuant
to such registrations.

 

    40

     

    

 

(k)
All amounts payable by Cellect and any Cellect Subsidiary to all Persons involved in the research, development, conception
or reduction to practice of any Cellect IP Rights have been paid in full. All Cellect Employees, contractors and consultants who
were or are engaged in the development or invention of any Cellect IP Rights have entered into written agreements with Cellect
or with a Cellect Subsidiary by which they validly and irrevocably assigned to Cellect or its Subsidiaries all rights, title and
interests in and to such Cellect IP Rights (or all such rights, title and interests vested in Cellect or its Subsidiaries as a
matter of law), and, with respect to employees, have explicitly waived all rights to receive royalties or compensation in connection
therewith (including, without limitation, under Section 134 of the Israeli Patent Law (1967)) and any applicable non-transferable
rights, including moral rights.

Corporation immediately after the Effective Time on terms substantially identical to those enjoyed by Cellect and the Cellect Subsidiaries
immediately prior to the Effective Time except where the unavailability of such Cellect Permit would not constitute a Cellect Material

and scientific research procedures and in compliance with applicable regulations of the Drug Regulatory Agencies and other applicable
Legal Requirements, including 21 C.F.R. Parts 50, 54, 56, 58 and 312. Since January 1, 2012, neither Cellect nor any Cellect Subsidiary

at any time before or after the date of this Agreement, except for invoices or other communications related to agreements or dealings
in the Ordinary Course of Business or payments or obligations identified in this Agreement; and

 

(ii)  
promptly notify Cellect in writing, of: (i) the discovery by Quoin of any event, condition, fact or circumstance that occurred
or existed on or prior to the date of this Agreement and that caused or constitutes an inaccuracy in any representation or warranty
made by Quoin in this Agreement in a manner that causes the condition set forth in Section 7.1 not to be satisfied; (ii)
any event, condition, fact or circumstance that occurs, arises or exists after the date of this Agreement and that would cause
or constitute an inaccuracy in any representation or warranty made by Quoin in this Agreement in a manner that causes the condition
set forth in Section 7.1 not to be satisfied if: (A) such representation or warranty had been made as of the time of the
occurrence, existence or discovery of such event, condition, fact or circumstance; or (B) such event, condition, fact or circumstance
had occurred, arisen or existed on or prior to the date of this Agreement; (iii) any breach of any covenant or obligation of Quoin
in a manner that causes the condition set forth in Section 7.2 not to be satisfied; and (iv) any event, condition, fact
or circumstance that would reasonably be expected to make the timely satisfaction of any of the conditions set forth in Article
6, Article 7, or Article 8 impossible or materially less likely. No notification given to Cellect pursuant to
this Section 4.4(b) shall change, limit or otherwise affect any of the representations, warranties, covenants or obligations
of Quoin contained in this Agreement or the Quoin Disclosure Schedule for purposes of Section 7.1.

Section 4.5
No Solicitation.

 

(a)   
Each Party agrees that neither it nor any of its Subsidiaries shall, nor shall it nor any of its Subsidiaries authorize
or permit any of the Representatives retained by it or any of its Subsidiaries to directly or indirectly: (i) solicit, initiate,
respond to or take any action to facilitate or encourage any inquiries or the communication, making, submission or announcement
of any Acquisition Proposal or Acquisition Inquiry or take any action that could reasonably be expected to lead to an Acquisition
Proposal or Acquisition Inquiry; (ii) enter into or participate in any discussions or negotiations with any Person with respect

or enter into any letter of intent or similar document or any Contract contemplating or otherwise relating to any Acquisition Transaction
(an “Acquisition Agreement”); or (vi) grant any waiver or release under any confidentiality, standstill
or similar agreement (other than to the other Party).

 

(b)   
Notwithstanding anything contained in Section 4.5(a), prior to receipt of the Required Quoin Stockholder Vote, in
the case of Quoin, or the Required Cellect Shareholder Vote, in the case of Cellect, such Party, (i) may enter into discussions
or negotiations with, any Person that has made (and not withdrawn) a bona fide, unsolicited, Acquisition Proposal, which
such Party’s Board of Directors determines in good faith, after consultation with its independent financial advisor, if any,
and its outside legal counsel, constitutes, or would reasonably be expected to result in, a Superior Offer, and (ii) thereafter
furnish to such Person non-public information regarding such Party pursuant to an executed confidentiality agreement containing
provisions (including nondisclosure provisions, use restrictions, non-solicitation provisions, no hire provisions and “standstill”
provisions) at least as favorable to such Party as those contained in the Confidentiality Agreement, but in each case of the foregoing
clauses (i) and (ii), only if: (A) neither such Party nor any Representative of such Party has breached this Section 4.5;
(B) the Board of Directors of such Party determines in good faith based on the advice of outside legal counsel, that the failure
to take such action would constitute a breach of the fiduciary duties of the Board of Directors of such Party under applicable
Legal Requirements; (C) at least three (3) Business Days prior to furnishing any such non-public information to, or entering into
discussions with, such Person, such Party gives the other Party written notice of the identity of such Person and of such Party’s
intention to furnish nonpublic information to, or enter into discussions with, such Person; and (D) at least three (3) Business
Days prior to furnishing any such non-public information to such Person, such Party furnishes such non-public information to Quoin
or Cellect, as applicable (to the extent such non-public information has not been previously furnished by such Party to Quoin or
Cellect, as applicable). Without limiting the generality of the foregoing, each Party acknowledges and agrees that, in the event
any Representative of such Party (whether or not such Representative is purporting to act on behalf of such Party) takes any action
that, if taken by such Party, would constitute a breach of this Section 4.5 by such Party, the taking of such action by
such Representative shall be deemed to constitute a breach of this Section 4.5 by such Party for purposes of this Agreement.

 

    65

     

    

 

(c)   
If any Party or any Representative of such Party receives an Acquisition Proposal or Acquisition Inquiry at any time during
the Pre-Closing Period, then such Party shall promptly (and in no event later than 24 hours after such Party becomes aware of such
Acquisition Proposal or Acquisition Inquiry) advise the other Party orally and in writing of such Acquisition Proposal or Acquisition
Inquiry (including the identity of the Person making or submitting such Acquisition Proposal or Acquisition Inquiry, and the terms
thereof). Such Party shall keep the other Party fully informed, on a current basis, in all material respects with respect to the
status and terms of any such Acquisition Proposal or Acquisition Inquiry and any modification or proposed modification thereto.
In addition to the foregoing, each Party shall provide the other Party with at least five (5) Business Days’ written notice
of a meeting of its board of directors (or any committee thereof) at which its board of directors (or any committee thereof) is
reasonably expected to consider an Acquisition Proposal or Acquisition Inquiry it has received.

 

(d)   
Each Party shall and shall cause its respective Representatives to, cease immediately and cause to be terminated, and shall
not authorize or knowingly permit any of its or their Representatives to continue, any and all existing activities, discussions
or negotiations, if any, with any third party conducted prior to the date hereof with respect to any Acquisition Proposal. The
Parties shall promptly (and in any event within three (3) Business Days following the date hereof) request in writing each Person
which as heretofore executed a confidentiality agreement in connection with its consideration of an Acquisition Proposal to return
all confidential information heretofore furnished to such Person by or on behalf of the respective Party, and such Party shall
use commercially reasonable efforts to have such information returned or destroyed (to the extent destruction of such information
is permitted by such confidentiality agreement).

 

Section 4.6

ADDITIONAL AGREEMENTS OF THE PARTIES

 

Section 5.1       
Registration Statement.

 

(a)   
As promptly as practicable after the execution and delivery of this Agreement, Cellect and Quoin shall cooperate in preparing
and shall cause to be filed with the SEC mutually acceptable proxy materials relating to the Cellect Shareholders Meeting (together
with all amendments thereof or supplements thereto, the “Proxy Statement”), and Cellect shall prepare
and file with the SEC registration statement on Form F-4 (the “F-4 Registration Statement” and together
with the prospectus contained in the F-4 Registration Statement and the Proxy Statement, the “Proxy Statement/Prospectus”),
in which the Proxy Statement/Prospectus shall be included, covering the ADRs to be issued in the Merger. Each of Cellect and Quoin
shall use all reasonable efforts to cause the Proxy Statement to be cleared by the SEC, and the F-4 Registration Statement to become
effective under the Securities Act, as soon as practicable after the date of such filing and to keep the F-4 Registration Statement
effective as long as is necessary to consummate the Merger. Prior to the effective date of the F-4 Registration Statement, Cellect
shall take all actions reasonably required under any applicable federal securities laws or applicable laws of any state in connection
with the issuance of ADSs in the Merger. The Proxy Statement/Prospectus shall include, among other things, (i) the recommendation
of the board of directors of Cellect that Cellect’s stockholders vote in favor of approval and adoption of this Agreement
and the transactions contemplated hereby (including, without limitation, the Merger), and (ii) the opinion of Cassel Salpeter &
Co., LLC referred to in Section 3.26. Each of Cellect and Quoin shall use all commercially reasonable efforts to cause the
Proxy Statement/Prospectus to be mailed to the holders of Cellect Shareholders and Quoin Stockholders as promptly as practicable
after the F-4 Registration Statement becomes effective and, after the Proxy Statement/Prospectus shall have been so mailed, promptly
circulate amended, supplemental or supplemented proxy materials and, if required in connection therewith, resolicit proxies.

 

(b)   
Cellect shall make, and Quoin shall cooperate in, all necessary filings with respect to the Merger and the transactions
contemplated thereby under the Securities Act and all applicable Israeli securities laws and regulation and United States state
securities and “blue sky” laws. Each party shall advise the other, promptly after receipt of notice thereof, of the
time of the effectiveness of the F-4 Registration Statement, the filing of any supplement or amendment thereto, the issuance of
any stop order relating thereto, the suspension of the qualification of ADSs issuable in connection with the Merger for offering
or sale in any jurisdiction, or of any SEC request for an amendment to the Proxy Statement/Prospectus or the F-4 Registration Statement,
SEC comments thereon and each party’s responses thereto or SEC requests for additional information. No amendment or supplement
to the Proxy Statement/Prospectus or the F-4 Registration Statement shall be filed by Cellect without providing Quoin a reasonable
opportunity to review and comment thereon. If, at any time prior to the Effective Time, Cellect or Quoin should discover any information
relating to either party, or any of their respective Affiliates, directors or officers, that should be set forth in an amendment
or supplement to the F-4 Registration Statement or the Proxy Statement/Prospectus, so that the documents would not include any
misstatement of a material fact or omit to state any material fact necessary to make the statements therein, in light of the circumstances
under which they were made, not misleading, the party that discovers such information shall promptly notify the other party hereto
and an appropriate amendment or supplement describing such information shall be promptly filed with the SEC and, to the extent
required by Legal Requirements, disseminated to the stockholders of Cellect and Quoin.

 

    67

     

    

 

(c)   
Cellect shall notify Quoin promptly of the receipt of any comments from the SEC or the staff of the SEC, if any, and of
any request by the SEC or the staff of the SEC, if any, for amendments or supplements to the Proxy Statement/Prospectus or the
F-4 Registration Statement or for additional information and shall supply Quoin with copies of all correspondence between Cellect
or any of its Representatives, on the one hand, and the SEC or the staff of the SEC, on the other hand, with respect to the Proxy
Statement/Prospectus or the F-4 Registration Statement or the Contemplated Transactions. Cellect shall use its commercially reasonable
efforts to respond as promptly as reasonably practicable to any comments of the SEC or the staff of the SEC with respect to the
Proxy Statement/Prospectus or the F-4 Registration Statement, and shall give Quoin and its counsel a reasonable opportunity to
participate in the formulation of any response to any such comments of the SEC or its staff.

 

(d)   
Cellect covenants and agrees that the Proxy Statement/Prospectus or the F-4 Registration Statement will not, at the time
that the Proxy Statement/Prospectus or the F-4 Registration Statement or any amendment or supplement thereto is filed with or submitted
to the SEC or is first mailed to the Cellect Shareholders, at the time of the Cellect Shareholders’ Meeting and at the Effective
Time, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary
in order to make the statements made therein, in light of the circumstances under which they were made, not misleading. Notwithstanding
the foregoing, Cellect makes no covenant, representation or warranty with respect to statements made in the Proxy Statement/Prospectus
or the F-4 Registration Statement (and the letter to stockholders, notice of meeting and form of proxy included therewith), if
any, based on information furnished in writing by Quoin specifically for inclusion therein. Each of the Parties shall use commercially
reasonable efforts to cause the Proxy Statement/Prospectus or the F-4 Registration Statement to comply with the applicable rules
and regulations promulgated by the SEC in all material respects. Quoin covenants and agrees that information furnished in writing
by Quoin specifically for inclusion in the Proxy Statement/Prospectus or the F-4 Registration Statement will not, at the time that
the Proxy Statement/Prospectus or the F-4 Registration Statement or any amendment or supplement thereto is filed with or submitted
to the SEC or is first mailed to the Cellect Shareholders, at the time of the Cellect Shareholders’ Meeting and at the Effective
Time, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary
in order to make the statements made therein, in light of the circumstances under which they were made, not misleading.

 

    68

     

    

 

(e)   
Each of the Parties shall use commercially reasonable efforts to cause the Proxy Statement/Prospectus or the F-4 Registration
Statement to comply with the applicable rules and regulations promulgated by the SEC and the Companies Law, to respond promptly
to any comments of the SEC or its staff. Each of the Parties shall use commercially reasonable efforts to cause the Proxy Statement/Prospectus
or the F-4 Registration Statement to be submitted to the SEC and then mailed to the Cellect Shareholders as soon as reasonably
possible after the date hereof. Each Party shall promptly furnish to the other Party all information concerning such Party and
such Party’s subsidiaries and such Party’s stockholders that may be required or reasonably requested in connection
with any action contemplated by this Section 5.1. If any event relating to Quoin occurs, or if Quoin becomes aware of any
information, that should be disclosed in an amendment or supplement to the Proxy Statement/Prospectus or the F-4 Registration Statement,
then Quoin shall promptly inform Cellect thereof and shall cooperate fully with Cellect in filing such amendment or supplement
with the SEC and, if appropriate, in mailing such amendment or supplement to the shareholders of Cellect. No filing of, or amendment
or supplement to the Proxy Statement/Prospectus or the F-4 Registration Statement will be made by Cellect without providing Quoin
a reasonable opportunity to review and comment thereon.

 

(f)    
Each of Quoin and Cellect agree to provide promptly to the other such information concerning its business and audited financial
statements and affairs as, in the reasonable judgment of the providing party or its counsel, may be required or appropriate for
inclusion in the Proxy Statement/Prospectus or the F-4 Registration Statement, or in any amendments or supplements thereto, and
to cause its counsel and auditors to cooperate with the other’s counsel and auditors in the preparation of the Proxy Statement/Prospectus
or the F-4 Registration Statement. Cellect shall not include in the Proxy Statement/Prospectus or the F-4 Registration Statement
any information with respect to Quoin or its Affiliates, the form and content of which information shall not have been approved
by Quoin prior to such inclusion.

 

Section 5.2       
Quoin Stockholder Written Consent. Quoin shall obtain the Quoin Stockholder Written Consent for purposes of (i) adopting
this Agreement, and approving the Merger and the other actions contemplated by this Agreement (the “Quoin Stockholder
Matters”); (ii) acknowledging that the approval given thereby is irrevocable and that such stockholder is aware of
its rights to demand appraisal for its shares pursuant to Section 262 of the DGCL, a copy of which was attached thereto, and that
such stockholder has received and read a copy of Section 262 of the DGCL; and (iii) acknowledging that by its approval of the Merger
it is not entitled to appraisal rights with respect to its shares in connection with the Merger and thereby waives any rights to
receive payment of the fair value of its capital stock under the DGCL.

 

Section 5.3
Cellect Shareholders’ Meeting.

 

(a)   
As promptly as practicable after the date hereof, Cellect shall take all action necessary under applicable Legal Requirements
to call, give notice of (pursuant to publication of the Cellect Shareholders’ Meeting Notice in the F-4 Registration Statement)
and hold a meeting of the holders of Cellect Ordinary Shares for the purpose of seeking approval of the following items, (A) the
amendment of Cellect’s Articles of Association to increase the authorized Cellect Ordinary Shares, (B) the amendment of Cellect’s
Articles of Association to effect the name change of Cellect (subject to consent of the Israeli Companies Registrar), (C) to approve
the purchase by Cellect of a “Runoff” directors’ and officers’ liability insurance policy for a period
of seven years following the Closing, and (D) any other matter required, at the reasonable discretion of the Board of Directors
of Cellect and agreed to by Quoin, in order to give effect to the transactions contemplated under this Agreement (the matters contemplated
by the foregoing clauses (A)–(D), collectively, the “Cellect Shareholder Matters”) and (ii) mail
to the Cellect Shareholders as of the record date established for stockholders’ meeting of Cellect, the Proxy Statement (such
meeting, the “Cellect Shareholders’ Meeting”).

 

    69

     

    

 

(b)   
Cellect agrees that, subject to Section 5.3(c): (i) the Cellect Board of Directors shall recommend that the holders
of Cellect Ordinary Shares vote to approve the Cellect Shareholder Matters; (ii) the Proxy Statement shall include a statement
to the effect that the Cellect Board of Directors recommends that Cellect Shareholders vote to approve the Cellect Shareholder
Matters (the “Cellect Board Recommendation”); and (iii) (A) the Cellect Board Recommendation shall not
be withdrawn or modified in a manner adverse to Quoin, and no resolution by the Cellect Board of Directors or any committee thereof
to withdraw or modify the Cellect Board Recommendation in a manner adverse to Quoin shall be adopted or proposed and (B) the Cellect
Board of Directors shall not recommend any Acquisition Transaction (collectively with any failure to make or include the recommendation
as set forth in sub-sections (i) and (ii) above, an “Cellect Board Adverse Recommendation Change”).

 

(c)   
Notwithstanding the foregoing, at any time prior to the receipt of the Required Cellect Shareholder Vote, the Cellect Board
of Directors may make a Cellect Board Adverse Recommendation Change, if the Cellect Board of Directors has received an Acquisition
Proposal that the Cellect Board of Directors has determined in its reasonable, good faith judgment, after consultation with Cellect’s
outside legal counsel, constitutes a Superior Offer, the Cellect Board of Directors determines in its good faith judgment, after
consultation with Cellect’s outside legal counsel, that not making a Cellect Board Adverse Recommendation Change would reasonably
constitute a breach of its fiduciary obligations under applicable Legal Requirements; provided, however, that prior to Cellect
taking any action permitted under this Section 5.3(c), Cellect must promptly notify Quoin, in writing, before making a Cellect
Board Adverse Recommendation Change, of its intention to take such action with respect to a Superior Offer, which notice shall
state expressly that Cellect has received an Acquisition Proposal that the Cellect Board of Directors intends to declare a Superior
Offer and that the Cellect Board of Directors intends to make a Cellect Board Adverse Recommendation Change.

 

(d)   
Nothing contained in this Agreement shall prohibit Cellect or its Board of Directors from making any disclosure to the Cellect
Shareholders if the Cellect Board of Directors determines in good faith, after consultation with its outside legal counsel, that
such disclosure is required for the Cellect Board of Directors to comply with its fiduciary duties to the Cellect Shareholders
under applicable Legal Requirements; provided, however, that in the case of any such disclosure or public statement shall
be deemed to be a Cellect Board Adverse Recommendation Change, Cellect has complied with the terms of Section 5.3(c).

 

Section 5.4    
Regulatory Approvals.

 

(a)   
Each Party shall use commercially reasonable efforts to take, or cause to be taken, all actions necessary to comply promptly
with all Legal Requirements that may be imposed on such Party with respect to the Contemplated Transactions and, subject to the
conditions set forth in Article 6 hereof, to consummate the Contemplated Transactions, as promptly as practicable. In furtherance
and not in limitation of the foregoing, each Party hereto agrees to file or otherwise submit, as soon as practicable after the
date of this Agreement, but in any event no later than 10 (ten) Business Days of the date hereof, all applications, notices, reports,
undertakings and other documents reasonably required to be filed by such Party with or otherwise submitted by such Party to any
Governmental Body with respect to the Contemplated Transactions, and to submit promptly any additional information requested by
any such Governmental Body.

 

    70

     

    

 

(b)   
Each of the Parties shall use its commercially reasonable efforts to (i) cooperate in all respects with each other in connection
with timely making all required filings and submissions and timely obtaining all related consents, permits, authorizations or approvals
pursuant to Section 5.4(a); and (ii) keep Quoin or Cellect, as applicable, informed in all material respects and on a reasonably
timely basis of any communication received by such Party from, or given by such Party to, any Governmental Body relating to the
Contemplated Transactions. Subject to applicable Legal Requirements relating to the exchange of information, each Party shall,
to the extent practicable, give the other party reasonable advance notice of all material communications with any Governmental
Body relating to the Contemplated Transactions and each Party shall have the right to attend or participate in material conferences,
meetings and telephone or other communications between the other Parties and regulators concerning the Contemplated Transactions.

 

Section 5.5
Cellect Employee and Benefits Matters.

 

(a)   
All of the employees of Cellect will be employed by Cellect Biotherapeutics which will be sold at Closing pursuant to the
Specified Assets Agreement. Cellect Biotherapeutics shall be responsible for all accrued and unpaid compensation and benefits that
may be required to be paid to any current or former employees of Cellect or Cellect Biotherapeutics.

 

(b)   
In order to allow holders of Cellect Options granted under the 2014 Plan to exercise such Cellect Options following the
Closing, it is hereby agreed that the 2014 shall not be cancelled or amended following the Closing in a manner that adversely affects
the ability of holders of Cellect Options granted thereunder, to exercise such Cellect Options in accordance with their terms.

 

(c)   
This Section 5.5 shall be binding upon and inure solely to the benefit of each of the Parties to this Agreement.
Nothing in this Section 5.5, express or implied, will (i) constitute or be treated as an amendment of any Cellect Employee
Plan or Quoin Employee Plan (or an undertaking to amend any such plan), or (ii) confer any rights or benefits on any Person other
than Cellect and Quoin.

 

Section 5.6
Indemnification of Officers and Directors.

 

(a)   
From the Effective Time through the seventh anniversary of the date on which the Effective Time occurs, each of Cellect
and the Surviving Corporation shall, jointly and severally, indemnify and hold harmless each person who is now, or has been at
any time prior to the date hereof, or who becomes prior to the Effective Time, a director or officer of Cellect (the “D&O
Indemnified Parties”), against all claims, losses, liabilities, damages, judgments, fines and reasonable fees, costs
and expenses, including attorneys’ fees and disbursements, incurred in connection with any claim, action, suit, proceeding
or investigation, whether civil, criminal, administrative or investigative, arising out of or pertaining to the fact that the D&O
Indemnified Party is or was a director or officer of Cellect, whether asserted or claimed prior to, at or after the Effective Time,
to the fullest extent permitted under the Companies Law and in the case of the Surviving Corporation to the fullest extent permitted
under the DGCL.

 

    71

     

    

 

(b)   
The Articles of Association of Cellect and the certificate of incorporation and bylaws of the Surviving Corporation shall
contain, and Cellect shall cause the certificate of incorporation and bylaws of the Surviving Corporation to so contain, provisions
no less favorable with respect to indemnification, advancement of expenses and exculpation of present and former directors and
officers of each of Cellect than are presently set forth in the Articles of Association of Cellect and the certificate of incorporation
and bylaws of Quoin, as applicable, which provisions shall not be amended, modified or repealed for a period of seven years’
time from the Effective Time in a manner that would adversely affect the rights thereunder of individuals who, at or prior to the
Effective Time, were officers or directors of Cellect.

 

(c)   
Cellect shall purchase a “tail” insurance policy for Cellect’s officers and directors with an effective
date as of the Closing Date, which shall remain effective for seven years following the Closing Date, with at least the same coverage
and amounts and containing the same terms and conditions that are not less favorable to the Cellect officers and directors than
the Existing Cellect D&O Policies.

referred to in this Section 5.6 in connection with their enforcement of their rights provided in this Section 5.6

 

(e)   
The provisions of this Section 5.6 are intended to be in addition to the rights otherwise available to the D&O
Indemnified Parties by law, charter, statute, bylaw, Articles of Association or agreement. The obligations of Cellect under this
Section 5.6 shall survive the consummation of the Merger and shall not be terminated or modified in such a manner as to
adversely affect any D&O Indemnified Party to whom this Section 5.6 applies without the consent of such affected D&O
Indemnified Party (it being expressly agreed that the D&O Indemnified Parties to whom this Section 5.6 applies, as well
as their heirs and representatives, shall be third party beneficiaries of this Section 5.6, each of whom may enforce the
provisions of this Section 5.6).

 

(f)    
In the event Cellect or the Surviving Corporation or any of their respective successors or assigns (i) consolidates with
or merges into any other Person and shall not be the continuing or surviving corporation or Entity of such consolidation or merger,
or (ii) transfers all or substantially all of its properties and assets to any Person, then, and in each such case, proper provision
shall be made so that the successors and assigns of Cellect or the Surviving Corporation, as the case may be, shall succeed to
the obligations set forth in this Section 5.6. Cellect shall cause the Surviving Corporation to perform all of the obligations
of the Surviving Corporation under this Section 5.6.

 

Section 5.7
Additional Agreements. The Parties shall (a) use commercially reasonable efforts to cause to be taken all actions
necessary to consummate the Contemplated Transactions and (b) reasonably cooperate with the other Parties and provide the other
Parties with such assistance as may be reasonably requested for the purpose of facilitating the performance by each Party of its
respective obligations under this Agreement and to enable the Surviving Corporation to continue to meet its obligations under this
Agreement following the Closing. Without limiting the generality of the foregoing, each Party to this Agreement: (i) shall make
all filings and other submissions (if any) and give all notices (if any) required to be made and given by such Party in connection
with the Contemplated Transactions; (ii) shall use commercially reasonable efforts to lift any injunction prohibiting, or any other
legal bar to, the Contemplated Transactions; and (iii) shall use commercially reasonable efforts to satisfy the conditions precedent
to the consummation of this Agreement. Quoin shall use reasonable best efforts to cause to be taken all actions necessary to consummate
the Quoin Financing prior to the Closing.

Party shall not, and shall not permit any of its Subsidiaries or any Representative of such Party to, issue any press release or
make any disclosure (to any customers or employees of such Party, to the public or otherwise) regarding the Contemplated Transactions
unless: (a) the other Party has approved such press release or disclosure in writing; (b) such Party has determined in good faith,
upon the advice of outside legal counsel, that such disclosure is required by applicable Legal Requirements and, to the extent
practicable, before such press release or disclosure is issued or made, such Party advises the other Party of, and consults with
the other Party regarding, the text of such press release or disclosure; (c) such press release or disclosure is consistent with
previous press releases, public disclosures or public statements made jointly by the Parties (or individually, if approved by the
other Party); or (d) such press release or disclosure is to be issued or made in accordance with the provisions of Section 5.3(d).

 

Section 5.9
Listing. Cellect shall use its commercially reasonable efforts to: (a) maintain its existing listing on the NASDAQ
Capital Market and to obtain approval of the listing of the combined company on the NASDAQ Capital Market; (b) to effect the ADR
Ratio Adjustment, (c) without derogating from the generality of the requirements of clause “(a)” and to the extent
required by the rules and regulations of NASDAQ, to (i) prepare and submit a notification form for the listing of the ADRs to be
issued in the Merger, and (ii) to cause such ADRs to be approved for listing (subject to notice of issuance); and (d) to file an
initial listing for the ADRs on the NASDAQ Capital Market (the “Nasdaq Listing
Application”) and to cause such Nasdaq Listing Application to be approved
for listing (subject to official notice of issuance). Quoin will cooperate with Cellect as reasonably requested by Cellect with
respect to the Nasdaq Listing Application and promptly furnish to Cellect all information concerning Quoin and Quoin Stockholders
that may be required or reasonably requested in connection with any action contemplated by this Section 5.9.

 

Section 5.10
Tax Matters.

 

(a)   
Cellect, Merger Sub and Quoin shall use their respective commercially reasonable efforts to cause the Merger to qualify,
and agree not to, and not to permit or cause any Affiliate or any Subsidiary to, take any actions or cause any action to be taken
which would reasonably be expected to prevent the Merger from qualifying, as a “reorganization” under Section 368(a)
of the Code.

 

(b)   
This Agreement is intended to constitute, and the Parties hereby adopt this Agreement as, a “plan of reorganization”
within the meaning of Treasury Regulations Section 1.368-2(g). The Parties shall treat and shall not take any tax reporting position
inconsistent with the treatment of the Merger as a reorganization within the meaning of Section 368(a) of the Code for U.S. federal,
