The Company hereby issues to the Warrantholders 400 Warrants and undertakes to enter the Warrantholder in the Register as holder of such
Warrants. 
 Entitlement to all rights attaching to the Warrants shall be evidenced by the issue to the Warrantholder of a Certificate. One
Certificate shall be issued to the Warrantholder for all of the Warrants registered in its name. 
  

	2.2	 Subscription Rights 

Each Warrant confers the right (but not the obligation) (“Subscription Rights”) on the Warrantholder to subscribe in cash at
the Subscription Price for one Warrant Share on the terms set out in this Warrant Instrument. 
  

	2.3	 Adjustment Event 

If an Adjustment Event occurs, the number and nominal value of Warrant Shares which the Warrantholder is entitled to subscribe and (as
appropriate) the Subscription Price payable in respect of such subscription shall be adjusted in accordance with the provisions set out in Schedule 3. If requested by the Warrantholder in writing, the Company will use its commercially

  
 7 

 
reasonable efforts to cause its Auditors to certify the appropriate adjustment in accordance with Schedule 3 (which, for the avoidance of doubt, shall include paying any fee of the Auditors in
connection with such certification). If the Auditors are unwilling or unable to perform any calculation or other task required of them under this Warrant Instrument, the Company and the Warrantholder shall appoint another reputable firm of
accountants agreed between them (or in the absence of agreement nominated by the President of the Institute of Chartered Accountants of England and Wales) to perform the calculation or task. 

 

	3.	 EXERCISING SUBSCRIPTION RIGHTS 

 

	3.1	 Timing 

Subject to Clause 3.5, a Warrantholder may at any time either: (i) on or after Admission or, if Admission does not occur by
31 January 2021, on or after 1 February 2021; or (ii) upon the occurrence of an Event (provided that an exercise of Subscription Rights which is conditional upon the occurrence of an Event shall be deemed to take effect immediately
prior to the occurrence of the relevant Event occurring), exercise its Subscription Rights in whole or part, by delivering to the Company a notice substantially in the form contained in the Certificate (“Notice of Subscription”)
together with: 
  

	 	(a)	 the Certificate for the Warrants in respect of which Subscription Rights are being exercised; and

  

	 	(b)	 a payment by telegraphic transfer to the Company’s Account (or such other mode of payment as the Company
and the Warrantholder shall agree) of the aggregate Subscription Price in respect of the Subscription Rights which are being exercised. 

  

	3.2	 Subject to the provisions of Clause 3.6 below, on any exercise of the Warrantholder’s Subscription Rights,
in lieu of payment of the aggregate Subscription Price in the manner specified in Clause 3.1(b) above, but otherwise in accordance with the requirements of this Clause 3.2, the Warrantholder may elect to authorise the Company to sell such number of
Warrant Shares as it indicates and deduct from such sale proceeds an amount equal to the aggregate Subscription Price payable for the Warrant Shares that have been sold (with the Company retaining such amounts), and with the net sale proceeds after
such deduction being used to fund the aggregate Subscription Price payable for the balance of the Warrant Shares that the Warrantholder wishes to subscribe for. The provisions of this Clause 3.2 shall only apply after Admission and to the extent the
relevant sale is in compliance with applicable securities laws. 

  

	3.3	 For the avoidance of doubt, where part only of the Warrantholder’s total Warrants are exercised, the
Company shall update the Register to record the remaining Warrants of the Warrantholder following the partial exercise of its Subscription Rights and shall issue to the Warrantholder an updated Certificate confirming the remaining Warrants in
respect of which it is recorded in the Register as the holder on the terms set out in this Warrant Instrument. 

  

	3.4	 Irrevocable Election  

Delivery of the items specified in Clause 3.1 to the Company shall, other than with the Company’s written consent, be an irrevocable
election by the Warrantholder to exercise the relevant Subscription Rights. 
  

	3.5	 Lapse 

All Subscription Rights not exercised shall lapse on the date falling ten years from the date of this Warrant Instrument (the
“Termination Date”). 

  
 8 

	3.6	 Restriction on Transfer of Common Shares 

In the event that the Warrantholder elects to exercise its Subscription Rights during the Restricted Period, the Warrantholder hereby
undertakes and agrees (i) not to Transfer any Common Shares it receives as a result of exercising any of the Warrants during the Restricted Period; and (ii) that it will only be able to elect to authorise the Company to sell Common Shares
in accordance with Clause 3.2 if the Board approves such action and the relevant underwriters consent to such action. The Company hereby confirms that the Company’s other Common Shares in issue at such time (other than the new Common Shares
issued pursuant to the Initial Public Offering) will, under the Company’s new Articles to be adopted in connection with the Initial Public Offering, also be subject to restrictions on Transfer during the Restricted Period (except where a
proposed Transfer is approved by the Board due to exceptional circumstances with the prior written consent of the relevant underwriters). 
  

	4.	 ISSUE OF SHARES UPON EXERCISE OF SUBSCRIPTION RIGHTS 

 

	4.1	 Allotment and Issue 

Following receipt of a validly completed and signed and dated Notice of Subscription, the Company shall: 

 

	 	(a)	 as soon as is reasonably practicable but in any event within three (3) Business Days after the Exercise
Date, resolve to allot and issue to the person identified in the relevant Notice of Subscription (“Allottee(s)”) the Warrant Shares specified in the Notice of Subscription and to enter the Allottee(s)’ name in the register of
members of the Company as the holder of the Warrant Shares issued to such Allottee(s); and 

  

	 	(b)	 within ten (10) Business Days of the allotment and issue of the Warrant Shares pursuant to this Clause 4
(“Warrant Share Delivery Date”), at the Company’s cost, send to the address stipulated in the Notice of Subscription share certificate(s) in respect of the Warrant Shares issued (if such Warrant Shares are held in certificated
form) and (in the event of a partial exercise by the Warrantholder) a balancing Certificate in respect of those Warrants which remain unexercised. 

  

	4.2	 Rights attaching to Warrant Shares 

The Warrant Shares allotted pursuant to the exercise of the Subscription Rights shall: 

 

	 	(a)	 be allotted and issued fully paid; 

 

	 	(b)	 rank pari passu with the fully paid Common Shares then in issue and have the rights set out in the Articles
relating to the Common Shares; and 

  

	 	(c)	 subject to the Articles, be entitled to receive any dividend or other distribution which has previously been
announced or declared provided that the record date by which the holder of Warrant Shares must be registered to participate in such dividend or other distribution is after the date on which the Warrant Shares are allotted and issued.

  

	4.3	 Rounding 

If the number of Warrant Shares falling to be allocated to the Warrantholder (or at its direction) on an exercise of Subscription Rights would
otherwise require a fraction of a Warrant Share to be allotted, the number of Warrant Shares to be so allotted will be rounded down to the nearest whole number of Warrant Shares.

covering such securities is effective under the Securities Act and such state law; (ii) an exemption from registration under the Securities Act and such state law is available; (iii) the Subscription Rights are exercised pursuant to the

Company and its subsidiaries which SVB has requested and which was relevant to its decision to acquire the relevant Warrants and to exercise the Warrants at the aggregate Subscription Price. SVB and its attorneys or other representatives have had
the opportunity to ask questions of, and receive answers from, representatives of the Company concerning such information and the Company’s financial condition and prospects. SVB is satisfied that it has received information with respect to all
matters that it considers material to its decision to make this investment; and 

  

	 	(e)	 It (a) is qualified by its knowledge and experience in financial and business matters to evaluate the
merits and risks of an investment in the Warrants and to make an informed decision relating thereto, (b) has the financial capability for making the investment and protecting its interests, and (c) can afford a complete loss of the
investment. The investment is a suitable one for SVB.

provision is made in connection with the Offer such that, upon the consummation thereof, and without any exercise of this Warrant by the Warrantholder or other action, the Warrantholder shall be entitled to receive the consideration under the Offer
to which the Warrantholder would have been entitled if the Warrantholder had exercised its rights pursuant to the Warrants immediately prior thereto net of the aggregate Subscription Price of the Warrants. The Warrantholder agrees that an amount
equal to the aggregate Subscription Price for his Warrants may be deducted from the Offer consideration and paid to the Company.

The Warrantholder shall have the right to: 
  

	 	(a)	 receive notice of all shareholders meetings of the Company and class meetings of the holders of Common Shares
but shall not be entitled to attend, speak or vote at those meetings in its capacity as a Warrantholder; and 

  

	 	(b)	 receive (at the same time as the relevant shareholders) a copy of any proposed written resolution of the
shareholders or any proposed written class consent of the holders of Common Shares but shall not be entitled to vote on those resolutions in its capacity as a Warrantholder. 

  
 12 

	6.5	 Transfer of Warrants  

 

	 	(a)	 The Warrants shall be freely transferable, in whole or in part, in accordance with the transfer provisions set
out in paragraph 2 of Schedule 2 to any of the following persons or entities (together, the “Permitted Transferees”): 

  

	 	(i)	 any Affiliate of the Warrantholder and if such Affiliate is no longer an Affiliate of the Warrantholder, such
Affiliate shall transfer such Warrants back to the Warrantholder or to an Affiliate of the Warrantholder; 

  

	 	(ii)	 an Eligible Assignee to whom all or a portion of the Loans has been transferred by the Warrantholder pursuant
to and in accordance with the Loan and Security Agreement; and 

  

	 	(iii)	 any person or entity approved by the Board. 

 

	 	(b)	 Subject to Clause 6.5(a) above and further subject to compliance with federal and applicable state or foreign
securities laws, and, as applicable, the provisions of the Warrants and the Articles as the same may be in effect from time to time, the registered holder of any warrants may surrender such Warrants at the principal office of the Company for
transfer or exchange. Within a reasonable time after notice to the Company from the registered holder of its intention to make such transfer or exchange and without expense (other than transfer taxes, if any) to such registered holder, the Company
shall issue in exchange therefor another Warrant or Warrants, containing the same provisions and subject to the same terms and conditions as the Warrant so surrendered, and for the same aggregate number of Warrant Shares so surrendered. Subject to
Clause 6.5(a) above, the new Warrant(s) shall be issued in the name of such person or registered assignee, as the registered holder of such surrendered Warrants may designate in writing. 

 

	7.	 REGISTRATION RIGHTS 

If at any time the Company files a registration statement to register the resale of any Common Shares pursuant to any of the Registration
Rights Agreements, the Company shall, subject to applicable securities laws, include the Warrant Shares in such registration as if the Warrantholder had been party to the Registration Rights Agreements. 

 

	8.	 MODIFICATION OF RIGHTS 

This Warrant Instrument may be modified only with the prior sanction of a Special Resolution. 

 

	9.	 LIQUIDATION 

  

	9.1	 Liquidation and Dissolutions 

If an order is made or an effective resolution is passed for the winding-up or dissolution of the
Company or if any other dissolution of the Company by operation of law is to be effected then the provisions of Clause 9.2 or 9.3 shall apply. 
  

	9.2	 Sanctioned Agreement 

If the winding-up or dissolution is for the purpose of a reorganisation or amalgamation pursuant to a
scheme of arrangement sanctioned by a special resolution of the Company, the terms of the scheme of arrangement will be binding on the Warrantholder. 

  
 13 

	9.3	 Non Sanctioned Agreement 

If Clause 9.2 does not apply, the Company shall immediately notify the Warrantholder, in writing, that such an order has been made or
resolution has been passed or other dissolution is to be effected. The Warrantholder shall be entitled at any time within three months after the date such notice is given to elect by notice in writing to the Company to be treated as if they had,
immediately before the date of the making of the order or passing of the resolution or other dissolution, exercised the Subscription Rights and they shall be entitled to receive out of the assets which would otherwise be available in the liquidation
to the holders of Common Shares, such a sum, if any, as they would have received had they been the holders of and paid for the Warrant Shares to which they would have become entitled by virtue of such exercise, after deducting from such sum the
amount which would have been payable by them in respect of the Warrant Shares if they had exercised the Subscription Rights. Nothing contained in this paragraph shall have the effect of requiring the Warrantholder to make any actual payment to the
Company. If no such notice is given by the Warrantholder within the three month period specified above, the Subscription Rights shall lapse without claim if an order is made or an effective resolution is passed for the
winding-up or the dissolution of the Company. 
  

	10.	 CERTIFICATES

	10.2	 Lost Certificates, etc 

If a Certificate is mutilated, defaced, lost, stolen or destroyed the Company will replace it provided that: 

 

	 	(a)	 the Warrantholder seeking the replacement provides the Company with such evidence and indemnity in respect of
the mutilation, defacement, loss, theft or destruction as the Company may reasonably require; 

  

	 	(b)	 the Warrantholder seeking the replacement pays the Company’s reasonable costs in connection with the issue
of the replacement;

 SCHEDULE 2 

THE REGISTER AND TRANSFERS 
  

	1.	 Register 

  

	1.1	 An accurate register of entitlement to the Warrants (the Register) will be kept by the Company at its
registered office in which the Company shall enter: 

  

	 	(a)	 the names and addresses of the persons for the time being entitled to be registered as the holders of the
Warrants; 

  

	 	(b)	 the number of Warrants held by every registered holder; and 

 

	 	(c)	 the date on which the name of every registered holder is entered in the Register in respect of the Warrants in
his name. 

  

	1.2	 Any change in the name or address of the Warrantholder shall be notified as soon as reasonably practicable
following such change to the Company which shall cause the Register to be amended accordingly. The Warrantholder and any person authorised by the Warrantholder may at all reasonable times during office hours inspect the Register and take copies of
or extracts from it or any part of it. 

  

	1.3	 The Company may treat the registered Warrantholder as the absolute owner of a Warrant and accordingly shall
not, except as ordered by a court of competent jurisdiction or as required by law, be bound to recognise any equitable or other claim to or interest in a Warrant on the part of any other person, whether or not it shall have express or other notice
of such a claim. 

  

	1.4	 The Warrantholder will be recognised by the Company as entitled to its Warrants free from any equity, set-off or cross-claim on the part of the Company against the original or any intermediate holder of the Warrants. 

  

	2.	 Transfers 

  

	2.1	 The Warrants may only be transferable in whole or in part by the Warrantholder to any other person or entity
permitted in accordance with Clause 6.5 of the Warrant Instrument. 

  

	2.2	 Every transfer of a Warrant shall be made by an instrument of transfer in the usual or common form or in any
other form which may be approved by the Directors. 

  

	2.3	 The instrument of transfer of a Warrant shall be executed by or on behalf of the transferor but need not be
executed by or on behalf of the transferee. The transferor shall be deemed to remain the holder of the Warrant until the name of the transferee is entered in the Register in respect of the Warrant being transferred. 

 

	2.4	 No fee shall be charged for any registration of a transfer of a Warrant or for the registration of any other
documents which in the opinion of the Directors require registration. 

  

	2.5	 The registration of a transfer shall be conclusive evidence of the approval by the Directors of such a
transfer. 

  

	3.	 Stock Exchange Dealings 

Provided that at the time of issue of Warrant Shares pursuant to the exercise of the Warrants, the Common Shares (or any of them) are quoted on
the Official List of the United Kingdom Listing Authority, admitted to trading on the Alternative Investment Market operated by The London Stock Exchange plc, and/or permission or approval has been granted for dealings therein or listing on any U.S.
National Securities Exchange or any Recognised Investment Exchange in any part of the world, the Company will apply to such exchange or body for 

  
 20 

 
permission to deal in, approval to list or for quotation of and Admission of such Warrant Shares (as the case may be) and shall use its commercially reasonable efforts to secure such permission
or quotation as soon as reasonably practicable after the issue of such Warrant Shares (which, for the avoidance of doubt, shall include paying any fee in connection thereto). 

  
 21 

 SCHEDULE 3 

ADJUSTMENTS TO WARRANT SHARES AND SUBSCRIPTION PRICE 
  

	1.	 If there is an Adjustment Event whilst any of the Warrants are outstanding, the number and nominal value of
Warrant Shares to be, or capable of being, subscribed on any subsequent exercise of the Subscription Rights and the Subscription Price will be adjusted in such manner as Board determines (acting in good faith). If requested by the Warrantholder in
writing within 7 Business Days of such determination by the Company, the Company will use its commercially reasonable efforts to cause its (i) Auditors or (ii) if the Auditors are unwilling (or unable) to so do, such other reputable,
independent and internationally recognised firm of accountants (determined in accordance with clause 2.3) (acting on the joint instructions of the WarranthoIder and the Company, as experts and not as arbitrators) to certify that, after such
adjustment: 

  

	 	(a)	 the total number of Warrant Shares to be, or capable of being, subscribed on any subsequent exercise of the
Subscription Rights conferred by the Warrants: 

  

	 	(i)	 will carry as nearly as possible (and in any event not less than) the same proportion (expressed as a
percentage of the total number of votes exercisable in respect of all the Equity Shares) of the votes available to be cast at a general meeting of the Company; and 

 

	 	(ii)	 will carry the same entitlement (expressed as a percentage of the total entitlement conferred by all the Equity
Shares) to participate in the profits and assets of the Company; 

 as would the total number of Warrant Shares which could
have been subscribed pursuant to the Subscription Rights conferred by the Warrants had there been no such adjustment and no such event giving rise to such adjustment; and 
  

	 	(b)	 the aggregate Subscription Price payable in order to subscribe for all the Warrant Shares will be as nearly as
possible the same as it was prior to such adjustment. 

  

	2.	 In calculating the aggregate entitlement to additional Subscription Rights under paragraph 1 above, any
entitlement to a fraction of a Warrant Share shall be rounded down to the nearest whole Warrant Share. 

  

	3.	 The Company will send the Warrantholder written notice of: 

 

	 	(a)	 any Adjustment Event as soon as reasonably practicable after the relevant resolution of the Board giving effect
to or sanctioning the same; 

  

	 	(b)	 any determination of the Board made in accordance with paragraph 1 of this Schedule 3 as soon as reasonably
practicable after the relevant resolution of the Board giving effect to or sanctioning the same; and 

  

	 	(c)	 any adjustments to the Subscription Rights together with a replacement Warrant Certificate evidencing the
Warrantholder’s adjusted Subscription Rights.

	2.3	 Adjustment Event

respect of such Adjustment Event .

Subscription Price in the manner specified in Clause 3.1(b) above, but otherwise in accordance with the requirements of this Clause 3.2, the Warrantholder may elect to authorise the Company to sell such number of Warrant Shares as it indicates and
deduct from such sale proceeds an amount equal to the aggregate Subscription Price payable for the Warrant Shares that have been sold (with the Company retaining such amounts), and with the net sale proceeds after such deduction being used to fund
the aggregate Subscription Price payable for the balance of the Warrant Shares that the Warrantholder wishes to subscribe for. The provisions of this Clause 3.2 shall only apply after Admission and to the extent the relevant sale is in compliance
with applicable securities laws.

representing such Warrants and without expense (other than transfer taxes, if any) to such Warrantholder, the Company shall issue in exchange therefor another Certificate in respect of such Warrants and the corresponding Warrant Shares. Subject to
Clause 6.5(a) or Clause 6.5(b) above (as applicable), the new Certificate(s) shall be issued in the name of such Person(s) or registered assignee(s), as the transferor Warrantholder of such surrendered Warrants may designate in writing.

  

	7.	 REGISTRATION RIGHTS 

If at any time the Company files a registration statement to register the resale of any Common Shares pursuant to any of the Registration
Rights Agreements, the Company shall, subject to applicable securities laws, include the Warrant Shares in such registration as if each Warrantholder had been party to the Registration Rights Agreements. 

 

	8.	 MODIFICATION OF RIGHTS 

This Warrant Instrument may be modified only with the prior sanction of a Special Resolution. 

 

	9.	 LIQUIDATION 

  

	9.1	 Liquidation and Dissolutions 

If an order is made or an effective resolution is passed for the winding-up or dissolution of the
Company or if any other dissolution of the Company by operation of law is to be effected then the provisions of Clause 9.2 or 9.3 shall apply. 

  
 14 

	9.2	 Sanctioned Agreement 

If the winding-up or dissolution is for the purpose of a solvent reorganisation or amalgamation
pursuant to a scheme of arrangement sanctioned by a special resolution of the Company, the terms of the scheme of arrangement will be binding on the Warrantholder. 
  

	9.3	 Non Sanctioned Agreement 

If Clause 9.2 does not apply, the Company shall immediately notify each Warrantholder, in writing, that such an order has been made or
resolution has been passed or other dissolution is to be effected. Each Warrantholder shall be entitled at any time within three months after the date such notice is given to elect by notice in writing to the Company to be treated as if they had,
immediately before the date of the making of the order or passing of the resolution or other dissolution, exercised their Subscription Rights and they shall be entitled to receive out of the assets which would otherwise be available in the
liquidation to the holders of Common Shares, such a sum, if any, as they would have received had they been the holders of and paid for the Warrant Shares to which they would have become entitled by virtue of such exercise, after deducting from such
sum the amount which would have been payable by them in respect of the Warrant Shares if they had exercised their Subscription Rights. Nothing contained in this paragraph shall have the effect of requiring the Warrantholder to make any actual
payment to the Company. If no such notice is given by a Warrantholder within the three month period specified above, the Subscription Rights held by that Warrantholder shall lapse without claim if an order is made or an effective resolution is
passed for the winding-up or the dissolution of the Company. 
  

	10.	 CERTIFICATES 

  

	10.1	 Issues of Certificates 

Within five Business Days of entering the name of the Warrantholder in the Register of the Company, the Company shall issue to the
Warrantholder a Certificate in respect of the Warrants in respect of which it is recorded in the Register as the holder. 
  

	10.2	 Lost Certificates, etc 

If a Certificate is mutilated, defaced, lost, stolen or destroyed the Company will replace it provided that: 

 

	 	(a)	 the Warrantholder seeking the replacement provides the Company with such evidence and indemnity in respect of
the mutilation, defacement, and in the case of loss, theft or destruction, such indemnity, as the Company may reasonably require; 

  

	 	(b)	 the Warrantholder seeking the replacement pays the Company’s reasonable costs in connection with the issue
of the replacement; 

  

	 	(c)	 mutilated or defaced Certificates in respect of which replacements are being sought are surrendered.

THE REGISTER AND TRANSFERS 
  

	1.	 Register 

  

	1.1	 An accurate register of the holders of the Warrants from time to time (the Register) will be kept by the
Company at its registered office in which the Company shall enter: 

  

	 	(a)	 the names and addresses of the Persons for the time being entitled to be registered as the holders of the
Warrants; 

  

	 	(b)	 the number of Warrants held by every registered holder; and 

 

	 	(c)	 the date on which the name of every registered holder is entered in the Register in respect of the Warrants in
his name. 

  

	1.2	 Any change in the name or address of a Warrantholder shall be notified by that Warrantholder as soon as
reasonably practicable following such change to the Company which shall promptly cause the Register to be amended accordingly. Each Warrantholder and any Person authorised by any Warrantholder may at all reasonable times during office hours inspect
the Register and take copies of or extracts from it or any part of it. 

  

	1.3	 The Company may treat the registered Warrantholder as the absolute owner of a Warrant and accordingly shall
not, except as ordered by a court of competent jurisdiction or as required by law, be bound to recognise any equitable or other claim to or interest in a Warrant on the part of any other Person, whether or not it shall have express or other notice
of such a claim. 

  

	1.4	 Each Warrantholder will be recognised by the Company as entitled to its Warrants free from any equity, set-off or cross-claim on the part of the Company against the original or any intermediate holder of such Warrants. 

  

	2.	 Transfers 

  

	2.1	 The Warrants may only be transferable in whole or in part by any Warrantholder to any other Person permitted in
accordance with Clause 6.5 of the Warrant Instrument. 

  

	2.2	 Every transfer of a Warrant shall be made by an instrument of transfer in the usual or common form or in any
other form which may be approved by the Board. 

  

	2.3	 The instrument of transfer of a Warrant shall be executed by or on behalf of the transferor but need not be
executed by or on behalf of the transferee. The transferor shall be deemed to remain the holder of the Warrant until the name of the transferee is entered in the Register in respect of the Warrant being transferred. 

 

	2.4	 No fee shall be charged for any registration of a transfer of a Warrant or for the registration of any other
documents which in the opinion of the Board require registration. 

  

	2.5	 The registration of a transfer shall be conclusive evidence of the approval by the Board of such a transfer.

  

	3.	 Stock Exchange Dealings

are quoted on the Official List of the United Kingdom Listing Authority, admitted to trading on the Alternative Investment Market operated by The London Stock Exchange plc, and/or permission or approval has been granted for dealings therein or
listing on any U.S. National Securities Exchange or any Recognised Investment Exchange in any part of the world, the Company will apply to such exchange or body for permission to deal in, approval to list or for quotation of and Admission of such
Warrant Shares (as the case may be) and shall use its commercially reasonable efforts to secure such permission or quotation as soon as reasonably practicable after the issue of such Warrant Shares (which, for the avoidance of doubt, shall include
paying any fee in connection thereto). 

  
 21 

 SCHEDULE 3 

ADJUSTMENTS TO WARRANT SHARES AND SUBSCRIPTION PRICE 
  

	1.	 If there is an Adjustment Event whilst any of the Warrants are outstanding, the number and nominal value of
Warrant Shares to be, or capable of being, subscribed on any subsequent exercise of the Subscription Rights and the Subscription Price will be adjusted, with effect from the date and time of the Adjustment Event, in such manner as the Board
determines (acting in good faith) such that, after such adjustment: 

  

	 	(a)	 the total number of Warrant Shares to be, or capable of being, subscribed on any subsequent exercise of the
Subscription Rights conferred by the outstanding Warrants: 

  

	 	(i)	 will carry as nearly as possible (and in any event not less than) the same proportion (expressed as a
percentage of the total number of votes exercisable in respect of all the Fully Diluted Share Capital) of the votes available to be cast at a general meeting of the Company; and 

 

	 	(ii)	 will carry the same entitlement (expressed as a percentage of the total entitlement conferred on the Fully
Diluted Share Capital) to participate in the profits and assets of the Company; 

 as would the total number of Warrant
Shares which could have been subscribed pursuant to the Subscription Rights conferred by the outstanding Warrants had there been no such Adjustment Event giving rise to such adjustment; and 

 

	 	(b)	 the aggregate Subscription Price payable in order to subscribe for all the Warrant Shares subject to
outstanding Subscription Rights will be as nearly as possible the same as it was immediately prior to such adjustment. 

  

	 	(c)	 the Register will be updated accordingly by the Company. 

 

	2.	 In calculating the aggregate entitlement to additional Subscription Rights under paragraph 1 above, any
entitlement to a fraction of a Warrant Share shall be rounded down to the nearest whole Warrant Share. 

  

	3.	 The Company will send each Warrantholder written notice of: 

 

	 	(a)	 as soon as reasonably practicable after (and, in any event within 10 Business Days of) the date on which the
Adjustment Event is effected: 

  

	 	(i)	 the details of the Adjustment Event; 

 

	 	(ii)	 the details of the adjustments to the Subscription Rights and the Subscription Price made and as determined by
the Board in accordance with paragraphs 1 and 2 of this Schedule 3, 

 (an “Adjustment Notice”) together
with: 
  

	 	(b)	 a replacement Certificate evidencing the Warrantholder’s adjusted Subscription Rights.

  

	4.	 If a Warrantholder notifies in writing the Company within 5 Business Days of an Adjustment Notice being
delivered to it the Company that it disagrees (a “disputed matter”) with the calculation of the adjustment to the Subscription Rights and/or the Subscription Price calculated in accordance with paragraphs 1 and 2 of this Schedule 3,
the Company will, as soon as reasonably practicable and in any event within 10 Business Days thereafter, refer the matter for determination to an Expert. The Expert shall be appointed in accordance with Clause 2.3. 

  
 22 

	5.	 In respect of any disputed matter referred to the Expert: 

 

	 	(a)	 the Company and the Warrantholders will each co-operate with the Expert
in resolving the disputed matter as soon as reasonably possible and for that purpose will provide to them all such information and documents as they may reasonably require; 

 

	 	(b)	 the Expert shall act as experts and not as arbitrators and their decision shall (in the absence of manifest
error) be final and binding on the Company and all Warrantholders; and 

  

	 	(c)	 the Expert’s fees shall be borne by the Company.
