 5.5 The Company acknowledges that Nomura’s responsibilities as sponsor
pursuant to the Listing Rules are owed solely to the UK Listing Authority and that agreeing to act as sponsor does not of itself extend any duties or obligations to anyone else, including the Company.

and in connection with the Open Offer: 
  

	(a)	Nomura may receive and retain for its own benefit any commissions or brokerage or other benefit paid to or lawfully and properly received by it or its respective agents in

 6. THE PLACING
AND THE OPEN OFFER 
  
 6.1 Subject to the conditions set out in clause 2.1 and in reliance on the covenants, indemnities, representations, warranties and undertakings contained in this Agreement: 
  

	(a)	Nomura shall use its reasonable endeavours to seek to procure Placees for the Underwritten Units at the Subscription Price on the basis of the information contained in the Circular,
subject (save in respect of the UK Firm Placed Units) to a right of clawback as a result of Open Offer Placing Units being taken up under the Open Offer; and 

  

	(b)	Nomura shall, as agent for the Company, by means of the Circular and the Application Form, invite Qualifying Shareholders (subject always to clause 4.5) to apply to subscribe for
the Open Offer Placing Units at the Subscription Price and otherwise on the terms and conditions set out therein. 

  

 Page 16 








 6.2 Neither the Open Offer nor any of its terms and conditions shall be varied, extended, amended or withdrawn without
the prior written consent of Nomura. 
  
 6.3 Open Offer Placing Units in respect
of which Application Forms are (or are treated by the Company pursuant to the provisions set out below and of the Circular and of the Application Form as having been) lodged for acceptance by 3.00 p.m. on the Application Date (and which have not by
that time been rejected as a result of the Money Laundering Regulations 1993 and 2001), in each case in accordance with the terms of the Circular and the Application Form and which are accompanied by: 
  

	(a)	cheques which have not, before 3.00 p.m. on the Application Date, been notified to the Receiving Agent as not having been accepted by the drawee on first presentation; or


  

	(b)	other cleared remittances in accordance with the terms of the Circular and the Application Form, 

  
 for the full amount payable in respect of such Placing Units, are referred to in this Agreement as having been taken up,
PROVIDED THAT, at the discretion of the Company, Open Offer Placing Units may for the purpose of this Agreement be deemed to have been taken up by 3.00 p.m. on the Application Date if a cheque or
other remittance for the full amount payable in respect of such Open Offer Placing Units (and whether or not such cheque or other remittance shall be honoured) is received prior to 3.00 p.m. on the Application Date from an authorised person (as
defined in the FSMA) who shall have specified the Open Offer Placing Units concerned and undertaken to lodge in due course the relevant Application Form duly completed. 
  
 6.4 As soon as practicable after 3.00 p.m. on the Application Date and by not later than 8.00 a.m. on the first Dealing Day after the
Application Date, the Company will (or will procure that the Receiving Agent will) notify Nomura in writing of the number of Open Offer Placing Units which have been taken up and the number of Underwritten Units (and, for information only, of any
Committed Units) which have not been taken up. 
  
 6.5 The number of Underwritten
Units which have not been taken up shall be calculated as follows: 
  

											
	 A=
	  	(	  	B	  	)	  	x	  	(D-E)
	  	  	B+C	  	  	  

  
 where 
  
 A = the number of Underwritten Units which have not been taken up 
  
 B = the number of Placing Units which are the subject of the Placing Letters other
than the UK Firm Placed Units 
  
 C = the number of US Clawback Units

  

 Page 17 








 D = the aggregate number of UK Clawback Units and US Clawback Units 
  
 E = the aggregate number of UK Clawback Units and US Clawback Units which have been
taken up 
  
 6.6 Where cheques or bankers’ drafts in relation to an
Application Form have been dishonoured before 8.00 a.m. on the Application Date, the Open Offer Placing Units to which such Application Form relates will be treated as not having been taken up and, where the relevant application has been rejected
before 8.00 a.m. on the Application Date due to a failure to provide satisfactory evidence of identity in order to comply with the Money Laundering Regulations 1993 and 2001 in the manner contemplated in the Circular and the Application Form, the
Open Offer Placing Units to which such application relates will be treated as not having been taken up. 
  
 6.7 Nomura shall not have any obligations under this clause 6 in respect of any Underwritten Units which have not been notified to it in accordance with clause 6.4 as not having been taken up (calculated in accordance
with clause 6.5 above) or in respect of any Committed Units. The number of Underwritten Units notified to Nomura as not having been taken up (and calculated in accordance with clause 6.5 above) together with the UK Firm Placed Units are referred to
in this Agreement as the Final UK Placing Units. 
  
 6.8 Nomura
shall, in its absolute discretion, determine the identity of the proposed Placees (if any) for the Final UK Placing Units, the extent to which each Placee is to subscribe for the Final UK Placing Units and all other matters in respect of the
Placing, including the last time at which Placing Letters may be despatched, allocations pursuant thereto may be made and acceptances pursuant thereto received. 
  

6.9 If by 3.00 p.m. on the first Dealing Day after the Application Date or, if later, by such time on the Dealing Day immediately preceding the date of Admission,
there are Final UK Placing Units for which no Placees have been arranged, Nomura shall itself subscribe (as principal) for such Final UK Placing Units at the Subscription Price on the basis of the information contained in the Circular and the
Application Form (other than as to the time and method of acceptance and payment). 
  
 6.10 Nomura will procure that a schedule is delivered to the Company (or the Receiving Agent on behalf of the Company) of the names and registration details of the Placees allocated Final UK Placing Units together with details of any
subscription for such shares to be made by Nomura pursuant to clause 6.9 (the Placing Schedule), as soon as reasonably practical after it becomes aware of such details, and shall specify whether such Placing Units are to be issued in
certificated or uncertificated form. 
  
 6.11 For the avoidance of doubt, neither
Nomura nor any Placee it procures for the Underwritten Units shall have any obligation to subscribe for any Placing Units which are the subject of the US Subscription Agreement (unless, in the case of any Placee, it is also a party to the US
Subscription Agreement).

 7. COMPLETION 
  
 7.1 The Company: 
  

	(a)	hereby irrevocably and unconditionally authorises Nomura and its agents to procure that, subject to the allotment of the Placing Units by the Company, the Registrar shall take all

subscribers of such Warrants and New Shares in the proportions set out in the Placing Schedule and the Company will instruct the Registrar to register such persons as the holders of such Warrants and New Shares in the books of the Company and,
subject to the prior agreement of Nomura, to issue definitive warrant and share certificates accordingly; 
  

	(b)	as regards the Warrants and the New Shares which are required by Placees to be in uncertificated form, as soon as reasonably practicable following receipt of the Placing Schedule by
the Company and in any event (subject only to such receipt) by not later than the Dealing Day prior to Admission, the Board shall resolve to allot and issue (credited as fully paid) such Warrants and New Shares in uncertificated form, subject to
Nomura complying with its obligations pursuant to clause 7.8 and subject to the terms of the Circular and the Application Form, to Nomura and will procure that such Warrants and New Shares are credited by the Registrar in the proportions set out in

nominee for the subscribers of such Warrants and New Shares, and the Company will instruct the Registrar to register Nomura (or its nominee) as the holders of such Warrants and New Shares in the register of members; and 

  

	(c)	as soon as practicable on the date on which Admission becomes effective and subject only to Nomura complying with its obligations under clause 7.8, the Company shall deliver to
Nomura a duly executed declaration in the form set out in schedule 6 to the Listing Rules. 

  
 7.5 The New Shares and the Warrants shall be allotted and issued pursuant to clauses 7.3 and 7.4 free from all Adverse Interests and the New Shares will, and any new Ordinary Shares to be issued pursuant to any
exercise of the Warrants will, when allotted and issued, rank pari passu in all respects with the Ordinary Shares already in issue. 
  
 7.6 Subject to the Company complying with its obligations under clauses 4.6 and 7.4(c), Nomura hereby undertakes to the Company to procure the delivery on behalf of the

having complied with its obligations under clauses 7.2 to 7.5 inclusive and 7.7, Nomura shall pay or procure payment (including as agent for Placees in respect of the Final UK Placing Units to be subscribed by such Placees) to the Company of an

  

 Page 20 








 amount equal to the aggregate value at the Subscription Price of the Final UK Placing Units subject to deduction in
accordance with clause 8.4 of amounts payable in accordance with clauses 8.1 and 8.3 or incurred by Nomura and payable by the Company under clause 8.5, which payment shall constitute a complete discharge to Nomura of its obligations under clauses 6
and 7. It shall be the Company’s responsibility to procure that the Receiving Agent sends the Company, to an account designated by it, an amount representing the aggregate Subscription Price for the Open Offer Placing Units taken up under the
Open Offer. 
  
 8. COMMISSIONS AND
EXPENSES

	(b)	reimburse (whether or not Nomura’s obligations under this Agreement become unconditional or this Agreement is terminated) Nomura for all travel (including roadshow travel) and
other out-of-pocket expenses properly and reasonably incurred by it in connection with Admission, the Placing, the Open Offer, the US Subscription, the EGM, the allotment and issue of the Placing Units, this Agreement and the US Subscription

	(b)	(except where (c) below applies) such amount as equals any VAT suffered by Nomura in respect of any cost, charge or expense which gives rise to the payment or reimbursement or
deduction and which Nomura certifies is not recoverable by it by repayment or credit, that certificate to be conclusive save in the case of manifest error; and

	(c)	on any payment or reimbursement or deduction in respect of or indemnification for costs, charges or expenses incurred by Nomura as agent for the Company, such amount as equals the
amount included in the costs, charges or expenses in respect of VAT, provided that in such a case Nomura will use reasonable endeavours to procure that the actual supplier of the goods or services which Nomura received as agent issues its own VAT
invoice directly to the Company. 

  
 9.

Agreement, Admission, the Placing, the Open Offer and the US Subscription to be carried out and given full force and effect. 
  
 10. REPRESENTATIONS, WARRANTIES AND UNDERTAKINGS 
  
 10.1 The Company represents, warrants and undertakes to Nomura in the terms set out in
Schedule 2. The Company acknowledges that Nomura is entering into this Agreement in reliance on such representations, warranties and undertakings. Each representation, warranty and undertaking shall be construed separately and shall not be limited
or restricted by reference to or inference from the terms of any other representation, warranty and undertaking or any other term of this Agreement. 
  
 10.2 The Company shall not cause or permit (and shall procure that no other Group company nor any of its or their respective directors, officers, employees or agents nor
ThinkEquity Partners shall cause or, so far as they are able using their reasonable endeavours, permit) any event to occur or omit to do anything between the date of this Agreement and the date that is 30 Dealing Days after, as appropriate, the
Application Date or the date on which Nomura’s obligations under this Agreement cease in accordance with clause 2.3 and/or clause 12.1 which would make any statement in Schedule 2 untrue, inaccurate or misleading if such statement were repeated
at such date by reference to the facts and circumstances then existing. 
  
 10.3
The Company shall immediately notify Nomura (giving reasonable details) if it comes to the knowledge of the Company or any Director that any statement in Schedule 2 was breached or untrue, inaccurate or misleading at the date of this Agreement or
would be breached or untrue, inaccurate or misleading if repeated by reference to the facts and circumstances existing at any time during the period referred to in clause 10.2 or if the Company is in breach of any of its obligations under this
Agreement. 
  
 10.4 The Company undertakes to Nomura that it will not agree to any
alteration, revision or amendment of the terms or conditions of the US Subscription Agreement or waive (in whole or in part) or amend or extend or withdraw any condition thereof or grant any indulgence thereunder or proceed to completion thereof
without full satisfaction of all of the terms and conditions of the US Subscription Agreement without, in any such case, the prior written consent of Nomura. 
  

 Page 24 








 10.5 The Company agrees that Nomura and each Placee shall be entitled (as subscribers for Placing Units) to the same
remedies and rights of action against the Company, and to the same extent, as any person who acquires any Placing Units pursuant to the Open Offer on the basis of the Circular and the Application Form. 
  
 10.6 The representations, warranties and undertakings referred to in clauses 10.1 to 10.5
inclusive shall remain in full force and effect notwithstanding completion of all matters and arrangements referred to in, or contemplated by, this Agreement. 
  

10.7 Where any of the representations, warranties and undertakings are qualified by a reference to awareness and/or knowledge and/or information and/or belief, that
reference shall be deemed to include a statement to the effect that it has been given after making such enquiries (if any) as were reasonable and, for the avoidance of doubt, in the case of TransMIDTM, enquiry of the clinical team managing TransMID would be considered reasonable. 
  
 10.8 The Company undertakes to observe and comply with the provisions in respect of overseas shareholders set out in Part III of the
Circular under the heading “Overseas Shareholders and others”. 
  
 10.9
No action has been or will be taken in any jurisdiction by the Company that is intended to permit a public offering of Placing Units or possession or distribution of the Circular or any other offering material, in any country or jurisdiction where
action for that purpose is required other than the United Kingdom and the United States. 
  
 10.10 References in this Agreement to a representation, warranty or undertaking being (or not being) true and accurate or not being (or being) misleading “in any material respect” shall mean
material in the context of Admission and/or the Placing and/or the Open Offer and/or the US Subscription. 
  
 11. INDEMNITY 
  
 11.1 No
claim shall be made by the Company, or any of its subsidiary undertakings and associates, or the Directors against any Indemnified Person to recover any loss, damage, cost, charge or expense that the Company or any of its subsidiary undertakings or
associates, the Directors or any subscriber for or purchaser of Placing Units pursuant to the Placing, the Open Offer, the US Subscription or the arrangements contemplated by the Circular, the Press Announcement, this Agreement or the US
Subscription Agreement or any subsequent purchaser or transferee of any Placing Units may suffer or incur and which arises out of the carrying out by any Indemnified Person of obligations or services in connection with this Agreement, the US
Subscription Agreement or any other agreement relating to the Placing or the Open Offer or the US Subscription, or in connection with Admission, the Placing, the Open Offer, the US Subscription or the arrangements contemplated by the Circular, the
Press Announcement, this Agreement or the US Subscription Agreement except, in each case, if, and to the extent only that, the loss, damage, cost, charge or expense is finally determined to have arisen (otherwise than as a result of a payment made
or 
  

 Page 25 








 an obligation or liability to make payment arising under clause 11.2) and primarily from any negligence, fraud, bad faith
or wilful default of the relevant Indemnified Person or material breach of any obligations under this Agreement by the Indemnified Person or material breach by that Indemnified Person of duties or obligations imposed on such person by the Financial
Services Authority Handbook or Rules. 
  
 11.2 The Company undertakes to indemnify
each Indemnified Person against all or any claims (whether or not successful, compromised or settled), actions, liabilities, demands, proceedings or judgments (each a Claim) asserted or established against that Indemnified Person in
any jurisdiction by any subscriber for or purchaser of Placing Units pursuant to the Placing, the Open Offer, the US Subscription or the arrangements contemplated by the Circular, the Press Announcement, this Agreement or the US Subscription
Agreement or by any subsequent purchaser or transferee of any Placing Units or governmental agency or regulatory body or any other person whatsoever and against all losses, costs, charges or expenses (including legal fees) and taxes (other than UK
corporation tax incurred by the Indemnified Person on its overall net income) (each an Expense) which that Indemnified Person may reasonably suffer or incur (including, but not limited to, all Expenses suffered or incurred in disputing
any Claim and/or in establishing a right to be indemnified pursuant to this clause 11.2 and/or in seeking advice regarding any Claim or in any way related to or in connection with this indemnity) if the Claim or Expense arises, directly or
indirectly, out of or is connected with anything done or omitted to be done by any person (including that Indemnified Person) in connection with Admission, the Placing, the Open Offer, the US Subscription, or the arrangements contemplated by the
Circular, this Agreement or the US Subscription Agreement, including without limitation: 
  

	 	(i)	the Circular or other documents or materials in connection with Admission, the Placing, the Open Offer or the US Subscription not containing or fairly presenting, or being alleged
not to contain or not to fairly present, all information required to be contained therein or any statement therein being or being alleged to be in any material respect untrue, inaccurate, incomplete, misleading or not based on reasonable grounds
(except, insofar as such statement is based on any information that has been provided by Nomura to the Company expressly for use in the Circular as specified in Schedule 5); and/or 

  

	 	(ii)	the distribution, issue or approval of the Circular or other documents or materials in connection with Admission, the Placing, the Open Offer or the US Subscription (including the
issue or approval for the purpose of Section 21 of the FSMA of any financial promotion); and/or 

  

	 	(iii)	any breach or alleged breach by the Company of any of its obligations in this Agreement, the US Subscription Agreement or any other agreement to be entered into by it in connection
with Admission, the Placing, the Open Offer, the US Subscription or the arrangements contemplated by the Circular, the Press Announcement, this Agreement or the US Subscription Agreement; and/or 

  

 Page 26 









	 	(iv)	any failure or alleged failure by the Company, any of the Directors or any of its or his agents, employees or advisers to comply with the FSMA or the Listing Rules or any other
legal or regulatory requirements in any jurisdiction in relation to Admission, the Placing, the Open Offer, the US Subscription or the arrangements contemplated by the Circular, this Agreement or the US Subscription Agreement; and/or


  

	 	(v)	any failure or alleged failure by ThinkEquity Partners, its affiliates, any of its or their agents or employees to comply with the US Placing Procedures in connection with the offer
and sale of the US Subscription Units, 

  
 provided that:

  

	(a)	an Indemnified Person shall not be entitled to any indemnity from the Company under this clause 11.2 in relation to any Claim or Expense to the extent only that the Claim or Expense
is in respect of an unrealised or realised loss on any Placing Units that the Indemnified Person acquires pursuant to this Agreement or any expenses of sale of such Placing Units unless (but only to the extent that) such Claim or Expense results
from, directly or indirectly, the neglect or default of the Company or any breach by the Company of any of its obligations under this Agreement; 

  

	(b)	an Indemnified Person shall not be entitled to any indemnity under this clause 11.2 in relation to any Claim or Expense if, and to the extent only that, the Claim or Expense
concerned is finally determined to have arisen primarily from the negligence, fraud, bad faith or wilful default of the Indemnified Person, in each case otherwise than in relation to any of the contents of, or any omission from, the Circular or
other documents or materials in connection with Admission and/or the Placing and/or the Open Offer and/or the US Subscription; 

  

	(c)	an Indemnified Person shall not be entitled to recover from the Company under this clause 11.2 in relation to any Claim or Expense to the extent that such indemnification is not
permissible under Part V, Chapter VI of the Companies Act (Financial Assistance by a Company for the Acquisition of its own Shares); and 

  

	(d)	an Indemnified Person shall not be entitled to recover from the Company under this clause 11.2 in relation to any Claim or Expense if, and to the extent only that the Claim or
Expense results solely from a material breach by that Indemnified Person of duties or obligations imposed on the Indemnified Person by virtue of the Financial Services Authority Handbook or Rules. 

  
 11.3 Subject to any requirement of a relevant insurer, each Indemnified Person to whom clause
11.2 applies will promptly notify the Company in writing if it becomes aware of any Claim which may give rise to a liability under clause 11.2, will keep the Company informed (including providing copies of documentation to the extent permitted by
law, regulatory authority or contractual obligation (and provided further 
  

 Page 27 








 that where not so permitted by any contractual obligation, Nomura shall request a waiver thereof from the relevant
counterparty to permit such disclosure)) of the progress of any Claim and will consult with the Company with respect to the handling of any Claim. 
  
 11.4 The Company will (provided it is aware of the same, after due and careful enquiry) promptly notify Nomura of any limitation (whenever arising) on the extent to which
the Company and/or any of its subsidiary undertakings or associates may claim against any third party or parties and/or of any waiver or release of any right of the Company or any of its subsidiary undertakings or associates to so claim (each a
Limitation) in respect of anything which may arise, directly or indirectly, out of or is based upon or is in connection with Admission, the Placing, the Open Offer, the US Subscription or the subject matter of the obligations or
services to be performed under this Agreement, the US Subscription Agreement or in connection with Admission, the Placing, the Open Offer or the US Subscription by Nomura or on its behalf. Where any damage or loss is suffered by the Company for
which any Indemnified Person would otherwise be jointly and severally liable with any third party or third parties to the Company or any of its subsidiary undertakings or associates, the extent to which such loss will be recoverable from the
Indemnified Person shall be limited so as to be in proportion to the contribution of the Indemnified Person to the overall fault for such damage or loss, as agreed between all the parties, or, in the absence of agreement, as finally determined by a
court of competent jurisdiction but, in any event, the Indemnified Person shall have no greater liability than if the Limitation did not apply. 
  
 11.5 The degree to which any Indemnified Person shall be entitled to rely on the work of any adviser to the Company or any other third party will be unaffected by any
Limitation which the Company or any of its subsidiary undertakings or associates or any Director may have agreed with the third party. 
  
 11.6 Insofar as the Company has engaged any adviser on the basis that its liability to the Company arising out of any default by it or otherwise in connection with
Admission, the Placing, the Open Offer, the US Subscription or the arrangements contemplated by the Circular, the Press Announcement, this Agreement or the US Subscription Agreement is subject to any limitation, exclusion or restriction of liability
(a capped adviser), the liability of each Indemnified Person to the Company or any other person in respect of any default by that Indemnified Person under this Agreement, the US Subscription Agreement or otherwise in connection
with Admission, the Placing, the Open Offer, the US Subscription or the arrangements contemplated by the Circular, the Press Announcement, this Agreement or the US Subscription Agreement shall not exceed the amount for which that Indemnified Person
would have been liable after deducting any additional amount which that Indemnified Person would have been entitled to recover from the capped adviser, in the absence of the limitation, exclusion or restriction of the capped adviser’s
liability, by way of contribution to that Indemnified Person, in respect of the matter concerned. 
  
 11.7 If an Indemnified Person is liable for any liability suffered by, or is liable to make any contribution to, any person other than the Company in respect of the performance of its obligations under this Agreement
or the US Subscription 
  

 Page 28 








 Agreement, the Company will indemnify that Indemnified Person on an after tax basis for any amount which it would have
been entitled to recover from any third party or parties by way of contribution in respect of the matter concerned (pursuant to the Civil Liability (Contributions) Act 1978 or otherwise) but for a Limitation. 
  
 11.8 All sums payable to an Indemnified Person pursuant to this clause 11 shall be paid
within 30 days of written demand by such Indemnified Person. 
  
 12.
TERMINATION 
  
 12.1 If at any time on or before Admission:

  

	(a)	there has been a breach by the Company of any of its obligations under this Agreement which is material in the context of Admission and/or the Placing and/or the Open Offer and/or
the US Subscription; or 

  

	(b)	any matter or circumstance arises or pertains as a result of which any of the conditions set out in sub-clauses (a) to (e) inclusive and (g) to (1) inclusive in clause 2.1 will not
be satisfied at the required time(s) (if any) and continue to be satisfied as at Admission; or 

  

	(c)	it shall come to the notice of Nomura that any statement contained in the Circular, the Press Announcement or the Application Form is or has become untrue, incorrect or misleading
in any respect, or any matter has arisen, which would, if the Placing or the Open Offer was made at that time, constitute a material omission from the Circular, the Press Announcement or the Application Form and which, in any such case, is material
in the context of Admission and/or the Placing and/or the Open Offer and/or the US Subscription; or 

  

	(d)	any of the representations, warranties and undertakings contained, or referred to, in this Agreement is not, or has ceased to be, true and accurate by reference to the facts and
circumstances subsisting at that time and which, in any such case, Nomura considers to be material in the context of Admission and/or the Placing and/or the Open Offer and/or the Subscription Agreement or a matter has arisen which might reasonably
be expected to give rise to a claim under clause 11; or 

  

	(e)	in the reasonable opinion of Nomura there shall have occurred a material adverse change in or any development (including any development relating to the Group’s products or
drug candidates or any product or drug candidate reasonably likely to be a competitor of any of the Group’s products or drug candidates but not including any development relating to the pharmaceutical or biotechnology industry generally)
involving a prospective material adverse change in or affecting the condition (financial or otherwise), prospects, earnings, business affairs, properties, management, results of operations or financial condition of the Group taken as a whole,
whether or not arising in the ordinary course of business, as a result of which Nomura reasonably considers it to be impracticable, inappropriate or inadvisable to proceed with Admission, the Placing, the Open Offer, the US Subscription or the
underwriting of the Underwritten Units; or 

  

 Page 29 









	(f)	in the reasonable opinion of Nomura there shall have been such a change in national or international financial, political or economic conditions (including any interruption to
trading generally on the New York Stock Exchange, the NASDAQ, the American Stock Exchange, the Tokyo Stock Exchange, the London Stock Exchange or trading of any securities of the Company) or a declaration of a general moratorium on commercial
banking activities in the United Kingdom or New York by any United Kingdom, New York State or United States federal authorities or any outbreak or escalation of hostilities (including any such change or event which causes a change in financial
markets or any calamity or crisis or any disruption to trading generally) which, in any such case, Nomura reasonably considers would be likely materially to prejudice the implementation and the success of Admission and/or the Placing and/or the Open
Offer and/or the US Subscription and the distribution of the Placing Units, 

  
 Nomura may, in its absolute discretion (as the case may be), by notice in writing given to the Company, terminate this Agreement, in each case except to the extent specified in clause 12.3. 
  
 12.2 Nomura shall have no right to terminate this Agreement on or before Admission except as
provided in clause 12.1. 
  
 12.3 The termination of this Agreement (save to the
extent specified in this clause 12.3) pursuant to clauses 2.3 or 12.1 shall be without prejudice to: 
  

	(a)	any claim in respect of a breach of this Agreement prior to the termination; 

  

	(b)	any obligation of the Company in respect of Placing Units which have already been issued, subscribed and paid for, or sold and paid for, at the time of such termination (in which
case this Agreement shall continue to apply to such Placing Units and, in particular, clauses 1, 8, 9, 10, 11, this clause 12.3, clauses 13, 14 and clauses 16 to 22 inclusive will continue to apply and Nomura shall accordingly be entitled to the
fees and commissions referred to in clause 8.1); and 

  

	(c)	the provisions of clauses 1, 8, 9, 10, 11, this clause 12.3, clauses 13, 14 and 16 to 22 inclusive which will continue to apply except that Nomura shall not be entitled to receive
the fees and commissions referred to in clause 8.1. 

  
 13.
WITHHOLDING AND GROSSING-UP 
  
 13.1 All sums payable to Nomura or any other Indemnified Person (for the purposes of this clause 13 only, each a Recipient) under this Agreement shall be paid in pounds sterling free and clear of all
deductions or withholdings (whatsoever save only as provided in this Agreement or as is required by law). 
  

 Page 30 








 13.2 If any deduction or withholding is required by law from any such payment then the person making such payment shall
be obliged to pay the Recipient such additional sum as will, after such deduction or withholding has been made, leave the Recipient with the same amount as it would have been entitled to receive in the absence of any such requirement to make a
deduction or withholding. 
  
 13.3 If any tax authority brings into charge to tax
(or into any computation of income, profit or gains for the purposes of any charge to tax) any sum payable or paid to a Recipient or any sum deducted from any payment made by a Recipient in accordance with the terms of this Agreement (except, in
either case, the fees and commissions payable under clause 8.1) then the amount so payable or the amount which may be deducted shall be grossed up by such amount as will ensure that the total amount received or retained by the Recipient, less the
tax chargeable thereon taking into account the incurring of the costs by the Recipient which gave rise to the payment, places the Recipient in the same after tax position as if it had incurred no cost and accordingly no payment was required to be
paid by it. 
  
 14. MISCELLANEOUS 
  
 14.1 For the avoidance of doubt, the Company acknowledges and agrees that it is responsible
for any due diligence carried out in relation to the Company in relation to the Placing or the Open Offer and that neither Nomura nor any of its advisers shall be responsible to the Company or any Director for any due diligence in relation thereto
or for verifying the accuracy or fairness of any information published by or on behalf of the Company in connection with the Placing, the Open Offer or the US Subscription unless it or they have agreed in writing to take specific responsibility for
such due diligence or verification or such information has been provided by Nomura to the Company expressly for use in the Circular as specified in Schedule 5. 
  

14.2 The Company agrees that for the purpose of the Placing, the Open Offer and the US Subscription (including for the purposes of seeking to procure any Placees for
the Placing Units) and of obtaining Admission, Nomura shall not be responsible for the provision of or obtaining advice as to the requirements of any applicable laws or regulations of any jurisdiction nor shall any such person be responsible where
it or the Company has acted in the absence of such advice or in reliance on any advice obtained by the Company in respect thereof. 
  
 14.3 Each reference in this Agreement to Nomura by any description or in any capacity includes a reference to it in each other capacity in which it may act pursuant to
this Agreement or otherwise with the agreement of the Company in connection with the Placing and the Open Offer. The Company accordingly acknowledges that the representations, warranties, undertakings contained in this Agreement are given to Nomura
in connection with Admission, the Placing and the Open Offer in each case whether in its capacity as sponsor or otherwise. 
  
 14.4 The respective agreements, representations, warranties, undertakings, indemnities and other statements contained in or made pursuant to this Agreement are to have
effect, irrespective of anything revealed in any investigation made by or on behalf of any person, and will survive the issue, sale, transfer or delivery of and payment for Placing Units or completion of the Placing or the Open Offer. 
  

 Page 31

 16. TIME OF THE ESSENCE 
  
 Any time, date or period mentioned in this Agreement may be extended by agreement between the Company and Nomura but as regards any time,

such right or remedy or operate or be construed as a waiver or variation of the right or remedy or preclude its exercise at any subsequent time. No single or partial exercise of any such right or remedy shall preclude any other or further exercise
of such right or remedy or the exercise of any other right or remedy. The rights, powers and remedies of each party provided in this Agreement are cumulative and not exclusive of any rights, powers and remedies provided by law.
