determining royalty payments shall be determined by multiplying the Net Sales of the Combination Product in that country by the fraction (A/A+B) where A is the average sale price in the relevant Quarter (as hereinafter defined) of the Product in
that country when sold separately in finished form and B is the average sale price in the relevant Quarter of the Other Element in that country sold separately in finished form. 
  
 In the event that the average sale price of the Product in that country can be determined but the average sale price of the
Other Element in that country cannot be determined, Net Sales of the Product in that country for the purposes of determining royalty payments shall be calculated by multiplying the Net Sales of the Combination Product in that country by the fraction
(C/D) where C is the selling Party’s average sales price in the relevant Quarter of the Product and D is the average selling price in the relevant Quarter of the Combination Product in that country. 
  
 If the average sale price of the Other Element in that Quarter can be
determined but the average price of the Product in that country cannot be determined, Net Sales of the Combination Product in that country for the purposes of determining royalty payments shall be calculated by multiplying 

  

 14 

 
the Net Sales of the Combination Product in that country by the following formula: one (1) minus E/D where E is the average selling price in the relevant
Quarter of the Other Element in that country and D is the average selling price of the Combination Product in that country in the relevant Quarter. 
  
 If the average sale price of both the Product and the Other Element cannot be determined the calculation method for the royalty payments for the
Combination Product shall be negotiated and determined by both Parties in good faith and if the Parties fail to agree a calculation method within thirty (30) days of commencing such negotiations the matter shall be referred to the Expert’s
Decision procedure set out in Schedule 6.

	11.1	Promptly following the grant of each Product Licence granted by CAT pursuant to Clause 9.1.1 or 9.3.1, Chugai will prepare and deliver to CAT a Development Plan for the relevant
Development Antibody in the Territory and Chugai will thereafter use reasonable commercial efforts to: 

  

	 	11.1.1	meet the Milestones set out in such Development Plan and to develop and commercialise Diagnostic Antibody Products and/or Therapeutic Antibody Products as the case may be derived
from such Development Antibody; and 

  

	 	11.1.2	develop such Diagnostic Antibody Products and/or Therapeutic Antibody Products in a Major Market and to bring those Diagnostic Antibody Products and/or Therapeutic Antibody Products
to market in at least one clinical indication in a Major Market within the time frames set out in the Development Plan; and 

  

	 	11.1.3	satisfy market demand for such Diagnostic Antibody Products and/or Therapeutic Antibody Products. 

  

	11.2	The activities described in Clause 11.1 may be carried out by Chugai, its Affiliates or its sub-licensees provided always in such case nothing shall relieve Chugai of its
obligations under Clause 11.1 and a breach of those obligations by its Affiliates or sublicensees shall be deemed to be a breach by Chugai. 

  

	11.3	For the purposes of this Clause 11 “reasonable commercial efforts” shall mean efforts which are similar to the efforts used by Chugai in relation to other products under
similar commercial circumstances that have similar commercial value, status and potential to the Diagnostic Antibody Product or Therapeutic Antibody Product in question. Notwithstanding the foregoing, and for the avoidance of doubt, Chugai shall not
be required by this Clause 11 or otherwise to continue with its development or commercialisation of a particular Diagnostic Antibody Product, Therapeutic Antibody Product or Product in any country if for safety, efficacy, technical or business
reasons it decides in good faith to abandon the same and Chugai so notifies CAT in writing. 

  

 30 

	11.4	Chugai shall provide to CAT an annual report of its progress with each Development Plan together with any updates of such Development Plan where applicable.

  

	12	CAT ANTIBODY PRODUCTS 

  

	12.1	If Chugai has begun to develop a Therapeutic Antibody Product but has not filed an IND for such Therapeutic Antibody Product in a Major Market within [***] years of the grant of a
Product Licence by CAT in respect thereof then Chugai shall provide to CAT all relevant scientific, regulatory and technical information relating to such Therapeutic Antibody Product so that CAT can determine in its sole discretion whether to enter
into a licence agreement (a “CAT Antibody Product Licence Agreement”) with Chugai in respect of such Therapeutic Antibody Product pursuant to which CAT shall research, develop and commercialise such Therapeutic Antibody Product in
any country outside Japan under any applicable Chugai IP. Upon execution of such CAT Antibody Product Licence Agreement such Therapeutic Antibody Product shall, outside Japan, be a “CAT Antibody Product”. The [***] year period
specified in this Clause 12.1 may be extended by [***] year only upon written notice from Chugai to CAT and the payment of a non-refundable, non-creditable extension fee of [***] prior to the end of such [***] year period. 

 

	12.2	CAT shall within [***] days of receipt of a notice from Chugai under Clause 12.1, notify Chugai whether it wishes to enter into a CAT Antibody Product Licence Agreement. If CAT so
notifies Chugai, the Parties or their nominated Affiliates shall enter into a CAT Antibody Product Licence Agreement comprising the terms set out in Clauses 12.3, 12.4 and 12.5 and other terms typically found in agreements of like nature for similar
products, to be negotiated in good faith, and CAT shall be granted, to the extent Chugai is able, an exclusive, sub-licensable, royalty bearing license under the Chugai IP to enable it to research, develop and commercialise such CAT Antibody
Products in respect of the relevant Target in any country outside Japan. The licence to be granted to CAT by Chugai under this Clause shall only be in respect of the relevant CAT Antibody Product and shall only be to the extent needed by CAT to
research, develop and commercialise that CAT Antibody Product in respect of the 

  

 31 

	 	 
relevant Target. For the avoidance of doubt, any licence which may be granted by Chugai hereunder shall not prevent Chugai from researching, developing and
commercialising Other Products to the same Target in any country of the Territory. If CAT does not notify Chugai within the [***] days mentioned above, it shall no longer have the option to enter into a CAT Antibody Product Licence Agreement with
Chugai and Chugai’s rights under the relevant Product Licence shall continue in full force and effect, subject always to the terms of this Agreement. 

  

	12.3	CAT shall pay to Chugai in partial consideration for any CAT Antibody Product Licence Agreement entered into under Clause 12.2 and the licences contained therein:

  

	 	12.3.1	the milestone payments set out in Clauses 12.4 and 12.5 below; 

  

	 	12.3.2	a royalty of [***] on Net Sales of each CAT Antibody Product in each country outside Japan where the CAT Antibody Product falls within the scope of any Valid Claims of Patent Rights
comprised in the Chugai IP in that country; and 

  

	 	12.3.3	a royalty of [***] on Net Sales of each CAT Antibody Product in each country outside Japan where the CAT Antibody Product does not fall within the scope of any Valid Claims of
Patent Rights comprised in the Chugai IP in that country. 

  

	12.4	In partial consideration for any CAT Antibody Product Licence Agreement and the licences contained therein CAT shall, if the Chugai IP contains Valid Claims of Patent Rights which
cover or claim the Target to which a CAT Antibody Product is directed in a Major Market outside Japan, make to Chugai the following milestone payments for each CAT Antibody Product: 

  

	 12.4.1      
	 	Initiation of the first Phase I Clinical Trial or Phase I/IIa Clinical Trial in respect of the CAT Antibody Product anywhere in the Territory:	 	[***]
			
	 12.4.2  
	 	Initiation of the first Phase III Clinical Trial in respect of the CAT Antibody Product anywhere in the Territory:	 	[***]

  
  

 32 

	12.4.3      	 	Filing of the first BLA in respect of the CAT Antibody Product anywhere in the Territory:	 	[***]
			
	12.4.4	 	(i) First FDA approval anywhere in the Territory for first indication of the CAT Antibody Product:	 	[***]
			
	 	 	(ii) First FDA approval anywhere in the Territory for second indication of the CAT Antibody Product:	 	[***]

  

	12.5	In partial consideration for any CAT Antibody Product Licence Agreement and the licences contained therein CAT shall, if the Chugai IP does not contain Valid Claims of Patent Rights
which cover or claim Target to which a CAT Antibody Product is directed in a Major Market outside Japan, make to Chugai the following milestone payments for each CAT Antibody Product: 

  

	12.5.1      	 	Initiation of the first Phase I Clinical Trial or Phase I/IIa Clinical Trial in respect of the CAT Antibody Product anywhere in the Territory:	 	[***]
			
	12.5.2	 	Initiation of the first Phase III Clinical Trial in respect of the CAT Antibody Product anywhere in the Territory:	 	[***]
			
	12.5.3	 	Filing of the first BLA in respect of the CAT Antibody Product anywhere in the Territory:	 	[***]
			
	12.5.4	 	(i) First FDA approval anywhere in the Territory for first indication of the CAT Antibody Product:	 	[***]
			
	 	 	(ii) First FDA approval anywhere in the Territory for second indication of the CAT Antibody Product:	 	[***]

  

	12.6	For the avoidance of doubt the milestones set out in Clauses 12.4 and 12.5 above shall be payable in respect of each CAT Antibody Product directed against each Target.

  

 33 

	12.7	If Chugai and CAT enter into a CAT Antibody Product Licence Agreement as provided in Clause 12.2, then: 

  

	 	12.7.1	the term of such CAT Antibody Licence Agreement shall continue, unless earlier terminated, on a country by country basis until the later of the last to expire Valid Claim of any
Patent Rights comprised in the Chugai IP or for ten (10) years from First Commercial Sale of any such CAT Antibody Product in such country by CAT, its Affiliates, sub-licensees or nominees (provided that in the case of a country within the European
Union such ten (10) year period shall run from the date of First Commercial Sale of such CAT Antibody Product anywhere in the European Union); and 

  

	 	12.7.2	as applicable and commensurate with legislative and regulatory requirements, Chugai shall transfer to CAT or its nominee all BLAs and other regulatory filings and approvals for the
relevant CAT Antibody Product outside Japan. In the event that such a transfer is not possible, Chugai shall use reasonable endeavours to ensure that CAT has the benefit of the relevant BLAs and other regulatory filings and approvals and, to this
end, shall consent to any Regulatory Authority cross-referencing to the data and information on file with the Regulatory Authority in Japan as may be necessary to facilitate the transfer of such BLAs, regulatory filings and approvals to CAT and
Chugai agrees to complete whatever other procedures are reasonably necessary in relation to the same to enable CAT (either itself or in conjunction with a Third Party) freely to develop and sell the relevant CAT Antibody Product outside Japan at
CAT’s expense; 

  

	 	12.7.3	Chugai shall, as appropriate, provide CAT with all reasonable technical and other assistance in relation to CAT’s appointment of a Third Party manufacturer of the relevant CAT
Antibody Product; 

  

	 	12.7.4	 the CAT Antibody Licence Agreement shall contain terms providing that neither Party will do any act or thing or fail to do any act or thing which could delay or
jeopardise the grant of Marketing Approval for any Therapeutic Antibody Product to a Target in Japan or any CAT Antibody Product to the same Target in any other country and that each Party will provide to the other 

  

 34 

	 	    	all data, materials and other information (including but not limited to information relating to adverse events) which the other Party may require to comply with Regulatory
Requirements in Japan or any other country; and 

  

	 	12.7.5	Chugai shall have the sole right and responsibility at its sole discretion and with all reasonable assistance from CAT to file, prosecute and maintain the Patent Rights and any
other rights related to or contained in the Chugai IP which claim or cover the relevant CAT Antibody Product and or for the conduct of any lawsuits, claims or proceedings relating to them in all countries, including, without limitation any
interference or opposition proceedings. All applicable costs, including those of CAT in providing reasonable assistance and of the patent attorneys retained by Chugai, shall be the responsibility of Chugai. If, following execution of any CAT
Antibody Product Licence Agreement, Chugai determines not to prosecute and/or maintain any Patent Rights, or part thereof, comprised in the Chugai IP which claim or cover the CAT Antibody Product which is the subject of such CAT Antibody Product
Licence Agreement (whether by totally abandoning the same or otherwise), Chugai shall give written notice thereof to CAT not later than [***] days prior to any relevant filing or prosecution deadline and if CAT wishes to do so CAT shall be entitled
to prosecute and maintain such Patent Rights or part thereof at its own cost and expense and Chugai shall transfer to CAT all relevant files and provide all reasonable assistance to CAT, at Chugai’s cost and expense, in respect thereof.

  

	12.8	Nothing in this Clause 12 is intended to prevent Chugai from continuing to research, develop and commercialise in Japan any Therapeutic Antibody Product from which a CAT Antibody
Product is derived after the relevant CAT Antibody Product Licence Agreement is executed by the Parties. 

  

	13	DUE DILIGENCE BY CAT 

  

	13.1	Promptly following the execution of each CAT Antibody Product Licence Agreement entered into by Chugai and CAT, CAT will prepare and deliver to Chugai a Development Plan for such
CAT Antibody Product in the Territory (excluding Japan) and CAT will thereafter use reasonable commercial efforts to: 

  

	 	(a)	meet the Milestones set out in such Development Plan and to develop and commercialise CAT Antibody Products; 

  

 35 

	 	(b)	develop and commercialise CAT Antibody Products in at least one clinical indication within the time frames set out in the Development Plan; and 

  

	 	(c)	satisfy market demand for those CAT Antibody Products. 

  

	13.2	The activities described in Clause 13.1 may be carried out by CAT, its Affiliates or its sub-licensees provided always in such case nothing shall relieve CAT of its obligations
under Clause 13.1 and a breach of those obligations by its Affiliates or sublicensees shall be deemed to be a breach by CAT. 

  

	13.3	For the purposes of this Clause 13 “reasonable commercial efforts” shall mean efforts which are similar to the efforts used by CAT in relation to other products under
similar commercial circumstances that have similar commercial value, status and potential to the CAT Antibody Products in question. Notwithstanding the foregoing, and for the avoidance of doubt, CAT shall not be required by this Clause 13 or
otherwise to continue with its commercialisation or development efforts of a particular CAT Antibody Product in any country if for safety, efficacy, technical or business reasons it decides in good faith to abandon the same and so notifies Chugai in
writing. 

  

	13.4	CAT shall provide to Chugai an annual report of its progress with each Development Plan together with any updates of such Development Plan where applicable.

  

	13.5	If CAT has not filed an IND for a CAT Antibody Product in a Major Market within [***] years of the date of the relevant CAT Antibody Product Licence Agreement then CAT shall provide
to Chugai all relevant scientific, regulatory and technical information relating to such CAT Antibody Product so that Chugai can determine in its sole discretion whether to terminate the CAT Antibody Product Licence Agreement granted to CAT in
respect of the CAT Antibody Product. The [***] year period specified in this Clause may be extended by [***] only upon written notice from CAT to Chugai and the payment of a non-refundable, non-creditable extension fee of [***] prior to the end of
such [***] period. 

  

 36 

	13.6	Chugai shall within [***] days of receipt of a notice from CAT under Clause 13.5, notify CAT whether it wishes to terminate the CAT Antibody Product Licence Agreement. If Chugai so
notifies CAT, the CAT Antibody Product Licence Agreement shall terminate and CAT shall have no further rights in respect of that CAT Antibody Product. 

  

	14	PAYMENTS 

  

	14.1	CAT shall have the sole responsibility for the payment of all of CAT’s Third Party Royalty Obligations. 

  

	14.2	With respect to each Therapeutic Antibody Product, Chugai shall pay to CAT the following milestones for the events set out below. For the avoidance of doubt the milestones set out
in 14.2.1, 14.2.2, and 14.2.3 below shall be payable in respect of each Therapeutic Antibody Product directed against each Target. The milestone set out in 14.2.4 below shall be payable no more than twice: firstly on FDA approval for the first
indication of such Therapeutic Antibody Product and again (if applicable) on FDA approval for the second indication for such Therapeutic Antibody Product directed against each Target. No further milestone payments will be due or payable for such
Therapeutic Antibody Product: 

  

	 14.2.1      
	 	Initiation of the first Phase I Clinical Trial or Phase I/IIa Clinical Trial in respect of the Therapeutic Antibody Product anywhere in the Territory:	 	[***]
			
	 14.2.2
	 	Initiation of the first Phase III Clinical Trial in respect of the Therapeutic Antibody Product anywhere in the Territory:	 	[***]
			
	 14.2.3
	 	Filing of the first BLA in respect of the Therapeutic Antibody Product anywhere in the Territory:	 	[***]
			
	 14.2.4
	 	(i) First FDA approval anywhere in the Territory for first indication of the Therapeutic Antibody Product:	 	[***]

  
  
  
  

 37 

	 	 	(ii) First FDA approval anywhere in the Territory for second indication of the Therapeutic Antibody Product:	 	[***]

  

	14.3	Chugai shall pay to CAT the following royalties on Net Sales of Therapeutic Antibody Product: 

  

	 14.3.1      
	 	 AnnualNet Sales of less than [***]
	 	[***]
			
	 14.3.2
	 	 AnnualNet Sales of between [***] and [***]
	 	[***]
			
	 14.3.3
	 	 AnnualNet Sales of over [***]
	 	[***]

  

	14.4	With respect to Diagnostic Antibody Products, Chugai shall pay to CAT the following milestone payments for the events set out below. For the avoidance of doubt the milestones set
out below shall be payable in respect of each Diagnostic Antibody Product to meet the identified milestone: 

  

	 14.4.1      
	 	Filing of the first BLA in respect of the Diagnostic Antibody Product anywhere in the Territory	 	[***]
			
	 14.4.2
	 	First FDA approval in respect of the Diagnostic Antibody Product anywhere in the Territory	 	[***]

  

	14.5	Chugai shall pay to CAT a royalty of [***] of Net Sales of Diagnostic Antibody Products. 

  

	14.6	If any royalty payments due to Third Parties in respect of any Therapeutic Antibody Product exceed [***] of Net Sales of such Therapeutic Antibody Product (excluding CAT’s
Third Party Royalty obligations and any royalties payable in respect of the manufacture of such Therapeutic Antibody Product) then the royalties payable to CAT under Clause 14.3 shall be reduced according to the following formula:

  

	  	[***] 

  

 38 

	14.7	If it is determined by (i) an independent Third Party expert (appointed in accordance with the Expert’s Decision procedure set out in Schedule 6) or (ii) a judicial order by a
Court of competent jurisdiction as a result of an action between CAT and the Medical Research Council (“MRC”) that royalties are due on the sale of Other Products in a particular country under the agreement between CAT and the MRC
set out in Paragraph 1 of Schedule 3 as such agreement exists on the Commencement Date (the “Current MRC Agreement”), then Chugai shall pay to CAT a royalty of [***] of the Net Sales of such Other Product in that particular country.
For the avoidance of doubt nothing in this Clause 14.7 is intended to prevent or limit CAT’s freedom to amend or vary the Current MRC Agreement as CAT in its sole discretion sees fit. 

  

	14.8	The sums payable under Clauses 14.2 and 14.4 shall be paid by Chugai within [***] of the applicable milestone being achieved and no sums payable under Clauses 14.2 and 14.4 shall be
refundable or creditable against any other sum payable by Chugai hereunder for any reason. 

  

	14.9	All royalties due to CAT pursuant to any Product Licence or, if applicable, Other Product Licence shall be payable on a country by country basis until the later of ten (10) years
from the date of the First Commercial Sale of the relevant Product or until the expiry of the last to expire Valid Claim of Patent Rights comprised in the CAT Background Patent Rights or the CAT Foreground Patent Rights which Valid Claim would be
infringed by the sale of such Product in that country. In the case of a country within the European Union such ten (10) year period shall run from the date of First Commercial Sale of such Product anywhere in the European Union.

  

	14.10	Chugai shall make the payments due to CAT under Clauses 14.3, 14.5 or 14.7 in pounds sterling (or Euros if applicable at the time of payment) at Quarterly intervals. CAT shall make
any payments due to Chugai under Clause 12.3 in Japanese Yen at Quarterly intervals. Within [***] of the end of each Quarter after the First Commercial Sale of each Product in any country the payor Party shall prepare a statement which shall show on
a country by country basis for the previous Quarter all monies due to the payee Party. That statement shall include details of Net Sales broken down to show the country of the sales and the total Net Sales in such country and shall be submitted to
the payee Party within such [***] day period together with remittance of the monies due. 

  

 39 

	14.11	All payments shall be made free and clear of and without deduction or deferment in respect of any disputes or claims whatsoever and/or as far as is legally possible in respect of
any taxes imposed by or under the authority of any government or public authority. Any tax (other than VAT) which the payor Party is required to pay or withhold with respect of the payments to be made to the payee Party hereunder shall be deducted
from the amount otherwise due provided that, in regard to any such deduction, the payor Party shall give the payee Party such assistance, which shall include the provision of such documentation as may be required by any revenue authority and other
revenue services, as may reasonably be necessary to enable the payee Party to claim exemption therefrom or obtain a repayment thereof or a reduction thereof and shall upon request provide such additional documentation from time to time as is needed
to confirm the payment of tax. If by law, regulation or fiscal policy of a particular country, remittance of royalties in pounds sterling (or Euros if applicable) or Japanese Yen, as the case may be, is restricted or forbidden, notice thereof will
be promptly given to the payee Party, and payment of the royalty shall be made by the deposit thereof in local currency to the credit of such payee Party in a recognized banking institution designated by such payee Party, its Affiliates or
sublicensees, as applicable. When in any country a law or regulation that prohibits both the transmittal and deposit of such payments ceases to be in effect, all royalties that such payee Party would have been under obligation to transmit or deposit
but for the prohibition, shall forthwith be deposited or transmitted promptly to the extent allowable. 

  

	14.12	For converting any payments from Chugai to CAT on Net Sales of a Diagnostic Antibody Product, Therapeutic Antibody Product or Other Product made in any country, Net Sales shall
first be determined in Japanese Yen and shall be converted each Quarter interval into pounds sterling (or Euros if applicable) at the average of the bid and ask prices prevailing in Tokyo as of the close of the last Business Day of such Quarter in
which such royalty is due. If the last day of such Quarter is not a Business Day, then the closest preceding Business Day shall be used for such calculation. All such converted Net Sales shall be used to calculate the applicable royalty payable

  

 40 

	 	 
determined therefrom. For converting any payments from CAT to Chugai on Net Sales of a CAT Antibody Product made in any currency, Net Sales shall first be
determined in pounds sterling (or Euros if applicable) and shall be converted each Quarter into Japanese Yen at the average of the bid and ask prices reported in the Financial Times as of the close of the last Business Day of such Quarter in which
such royalty is due. If the last day of such Quarter is not a Business Day, then the closest preceding Business Day shall be used for such calculation. All such converted Net Sales shall be used to calculate the applicable royalty payable determined
therefrom. 

  

	14.13	The payor Party shall keep and shall procure that its Affiliates and sub-licensees keep true and accurate records and books of account containing all data necessary for the
calculation of the amounts payable by it to the payee Party pursuant to this Agreement. Those records and books of account shall be kept for [***] years following the end of the Year to which they relate. Upon the payee Party’s written request,
a firm of accountants appointed by agreement between the Parties or, failing such agreement within ten (10) Business Days of the initiation of discussions between them on this point and at the request of the payee Party a firm of accountants
appointed by the then current President of the Institute of Chartered Accountants of England and Wales in London: 

  

	 	14.13.1	shall be given access to and shall be permitted to examine and copy such books and records of the payor Party and its Affiliates upon twenty (20) Business Days notice having been
given by the payee Party and at all reasonable times on Business Days for the purpose of certifying that the Net Sales calculated by the payor Party, its Affiliates and its sub-licensees during any Year were reasonably calculated, true and accurate
or, if this is not their opinion, certify the Net Sales figure for such period which in their judgment are true and correct; 

  

	 	14.13.2	Prior to any such examination taking place, such firm of accountants shall undertake to the payor Party in a deed that they shall keep all information and data contained in such
books and records, strictly confidential and shall not disclose such information or copies of such books and records to any third person including the payee Party, but shall only use the same for the purpose of the calculations which they need to
perform in order to issue the certificate to which this Clause 14.13 envisages; 

  

 41 

	 	14.13.3	any such access examination and certification shall occur no more than once per year and will not go back over records more than two (2) years old; 

  

	 	14.13.4	The payor Party and its Affiliates shall make available personnel to answer queries on all books and records required for the purpose of that certification; and

  

	 	14.13.5	the cost of the accountant shall be the responsibility of the payor Party if the certification shows it to have underpaid monies to the payee Party by more than [***] and the
responsibility of the payee Party otherwise. 

  

	14.14	All payments due to the payee Party under the terms of this Agreement are expressed to be exclusive of value added tax howsoever arising and the payor Party shall pay to the payee
Party in addition to those payments all value added tax for which the payor Party is liable to account to H M Customs & Excise in relation to any supply made or deemed to be made for value added tax purposes on receipt of a tax invoice or
invoices from the payee Party. 

  

	14.15	All payments made to the payee Party under this Agreement shall be made to the bank account of the payee Party as notified by the payee Party to the payor Party from time to time.

  

	14.16	If the payor Party fails to make any payment to the payee Party hereunder on the due date for payment, without prejudice to any other right or remedy available to the payee Party it
shall be entitled to charge the payor Party interest (both before and after judgment) of the amount unpaid at the annual rate of LIBOR (London Interbank Offering Rate) plus two percent (2%) calculated on a daily basis until payment in full is made
without prejudice to the payee Party’s right to receive payment on the due date. 

  

 42 

	15	PATENT PROSECUTION AND INFRINGEMENT 

  

	15.1	CAT shall have the sole right and responsibility, at its sole discretion and cost and with reasonable assistance from Chugai to file, prosecute and maintain the CAT Background
Patent Rights and any CAT Foreground Patent Rights and for the conduct of any lawsuits, claims or proceedings including, without limitation, any interference or opposition proceeding relating thereto in all countries. All applicable costs, including
those of Chugai in providing reasonable assistance and of the patent attorneys retained by CAT, shall be the responsibility of CAT. 

  

	15.2	Subject to Clause 15.3 Chugai shall have the sole right and responsibility, at its sole discretion and with reasonable assistance from CAT to file, prosecute and maintain the Patent
Rights and any other rights related to or contained in the Chugai IP and for the conduct of any lawsuits, claims or proceedings relating to them in all countries, including, without limitation, any interference or opposition proceedings. All
applicable costs, including those of CAT in providing reasonable assistance and of the patent attorneys retained by Chugai, shall be the responsibility of Chugai. 

  

	15.3	Nothing in this Agreement is intended to restrict, or to be construed as restricting, Chugai’s right to file, obtain, maintain and/or enforce such Patent Rights in respect of
Targets and their utility as it sees fit provided always that Chugai shall have no right, subject to Clause 15.4, [***] For the avoidance of doubt, [***] 

  

	15.4	Notwithstanding the provisions of Clause 15.3, the Parties acknowledge and agree that it may, from time to time during the term of this Agreement, be necessary for Chugai [***].
Where Chugai reasonably considers it necessary to do so it shall [***]. CAT shall, [***]. 

  

	15.5	[***] 

  

	15.6	For the avoidance of doubt, the Parties hereby agree that [***]. 

  

	15.7	If CAT reasonably determines that [***]. 

  

	15.8	Each Party shall promptly report in writing to the other during the term of this Agreement any (i) known infringement or suspected infringement of any of the CAT IP or the Chugai IP
or (ii) unauthorised use or misappropriation of any Confidential Information by a Third Party of which it becomes aware, and shall provide the other Party with all available evidence supporting said infringement, suspected infringement or
unauthorised use or misappropriation. 

  

 43 

	15.9	If during the term of this Agreement a Third Party in any country where any Product is being imported, manufactured, used, or sold, notifies any of the Parties, their Affiliates or
licensees that such activity infringes or is alleged to infringe any issued patent either assigned to or licensed to such Third Party, then the Party so notified shall promptly notify the other Party in writing. 

  

	15.10	Each Party shall co-operate with the other Party, to the extent reasonably requested, in any legal action brought by or against the other Party or both of them or against their
Affiliates or sublicensees, in each case by a Third Party, in connection with the making, using or selling of any Product (“Action”). 

  

	15.11	Chugai shall have the sole responsibility at its sole discretion and expense to defend or prosecute any Action (other than Actions relating to the CAT IP which shall be CAT’s
sole responsibility) with respect to a Diagnostic Antibody Product, Therapeutic Antibody Product or Other Product. CAT shall provide all reasonable assistance in connection with any Action at Chugai’s expense (including CAT’s reasonable
attorneys’ fees). If Chugai finds it necessary to join CAT in such Action, CAT shall execute all papers and perform such other acts as may be reasonably required. Unless Chugai and CAT otherwise agree any amount recovered in any such Action
whether by judgment or settlement shall be retained by Chugai. In the event Chugai fails to defend or prosecute any Action within [***] days of learning of such Action, CAT shall have the sole right, but not obligation, to do so at its own cost and
expense. If CAT wishes to join Chugai in such suit or action, Chugai shall at its own cost and expense execute all papers and perform such other acts as may be reasonably required. Chugai may, at its option, join as a party in such suit and, at its
expense, be represented by counsel of its choice. Unless Chugai and CAT otherwise agree, any amount recovered in any such action or suit, whether by judgement or settlement, after payment to Chugai of its reasonable expenses (including
attorney’s fees), shall be paid to or retained by CAT. 

  

	15.12	 CAT shall have the sole responsibility at its sole discretion and expense to defend or prosecute any Action with respect to a CAT Antibody Product. Chugai shall
provide 

  

 44 

	 	 
all reasonable assistance in connection with any Action at CAT’s expense (including Chugai’s reasonable attorneys’ fees). If CAT finds it
necessary to join Chugai in such Action, Chugai shall execute all papers and perform such other acts as may be reasonably required. Unless Chugai and CAT otherwise agree any amount recovered in any such Action whether by judgment or settlement shall
be retained by CAT. In the event CAT fails to defend or prosecute within [***] days of learning of such Action, Chugai shall have the sole right, but not obligation, to do so at its own cost and expense. If Chugai finds it necessary to join CAT in
such suit or action, CAT shall at its own cost and expense execute all papers and perform such other acts as may be reasonably required. CAT may, at its option, join as a party in such suit and, at its expense, be represented by counsel of its

	16	CONFIDENTIALITY 

  

	16.1	Each Party undertakes and agrees to: 

  

	 	16.1.1	only use the Confidential Information for the purposes envisaged under this Agreement and not to use the same for any other purpose whatsoever; 

  

	 	16.1.2	ensure that only those of its officers and employees who are directly concerned with the carrying out of this Agreement have access to the Confidential Information on a strictly
applied “need to know” basis and are informed of the secret and confidential nature of it; 

  

	 	16.1.3	keep the Confidential Information secret and confidential and not directly or indirectly disclose or permit to be disclosed, make available or permit to be made available the same
to any Third Party for any reason without the prior written consent of the Disclosing Party; 

  

 45 

	 	16.1.4	ensure that the Confidential Information is not covered by any fixed or floating charge entered into at any time by it and not otherwise to establish a lien over or in any other way
encumber the same; and 

  

	 	16.1.5	not copy, reproduce or otherwise replicate for any purpose or in any manner whatsoever any Documents containing the Confidential Information, except that each party may retain one
copy of the Confidential Information for purposes of ensuring its compliance with this Agreement. 

  

	16.2	The obligations of confidence referred to in Clause 16.1 shall not extend to any Confidential Information which: 

  

	 	16.2.1	is or becomes generally available to the public otherwise than by reason of breach by a Recipient Party of the provisions of this Clause; 

  

	 	16.2.2	is known to the Recipient Party and is at its free disposal (having been generated independently by the Recipient Party or a Third Party in circumstances where it has not been
derived directly or indirectly from the Disclosing Party’s Confidential Information) prior to its receipt from the Disclosing Party provided that evidence of such knowledge is proven by competent written records; or 

  

	 	16.2.3	is subsequently disclosed to the Recipient Party without obligations of confidence by a Third Party owing no such obligations to the Disclosing Party in respect of that Confidential
Information; 

  

	 	16.2.4	is required by law to be disclosed (including, without limitation, as part of any regulatory submission or approval process); however, the Party seeking such disclosure shall
provide prompt written notice of this requirement to the Disclosing Party so that it may, if so advised, seek appropriate relief to prevent such disclosure provided always that in such circumstances such disclosure shall be only to the extent so
required and shall be subject to prior consultation with the Disclosing Party with a view to agreeing timing and content of such disclosure; 

  

 46

disclosure is required as part of any regulatory submission or approval process. 

  

	16.4	All Confidential Information owned by and disclosed by the Disclosing Party to the Recipient Party shall remain the property of the Disclosing Party. In the event that a court or
Competent Authority assumes partial or complete control over the assets of a Recipient Party based on the insolvency or bankruptcy of that Party, the Recipient Party shall: 

  

	 	16.4.1	promptly notify such court or Competent Authority: 

  

	 	16.4.2	(a) that Confidential Information received from the Disclosing Party under this Agreement remains the property of the Disclosing Party; and 

  

	 	16.4.3	(b) of the confidential obligations under this Agreement; and

	16.5	The obligations of the Parties under Clause 16.1 and 16.3 shall last for a period of seven (7) years from the disclosure of the Confidential Information or until the Confidential
Information is no longer secret and confidential, whichever is the earlier. 

  

	16.6	The Parties understand and agree that remedies in damages may be inadequate to protect against any breach of any of the provisions of this Clause 16 by either Party or their
employees, officers or any other person acting in concert with it or on its behalf. Accordingly, each Party shall be entitled to the granting of interim and final injunctive relief by a court of competent jurisdiction in the discretion of that court
against any action that constitutes any breach of this Clause 16. 

  

 47 

	16.7	Chugai shall be entitled to publish data and information obtained by it in the course of the development of Products or Other Products provided that (i) any such publication may not

	 	(a)	be set out in the relevant Award Agreement; 

  

	 	(b)	commence no earlier than the third anniversary of the relevant Date of Grant; and 

  

	 	(c)	expire no later than three years thereafter. 

  

	3.3	A Matching Share Award is a right to acquire Shares, granted under this Plan and having the following characteristics: 

  

 8

which may not in any event exceed 15% of his Annual Salary; 

  

	 	(b)	If a Matching Share Award is then granted to that Eligible Employee, the Award Holder will have the right to acquire a number of Shares at the Award Price which will be calculated
by applying a multiple to the aggregate number of his Committed Shares held by him when the Award is exercised; 

  

	 	(c)	A Matching Share Award shall lapse if and to the extent that the Award Holder ceases to hold his Committed Shares before he exercises that Award; 

  

	 	(d)	The number of Shares to be issued or transferred to an Award Holder on a valid exercise of his Matching Share Award will be calculated by applying a multiple to the number of
Committed Shares held by the Award Holder at the date of exercise of that Award. That multiple shall be: 

  

	 	(i)	set out in the relevant Award Agreement; 

  

	 	(ii)	calculated by reference to the applicable Exercise Condition; and 

  

	 	(iii)	may vary subject to performance and the length of time for which the Committed Shares are held, but subject to the following restrictions (and subject always to Rules 7.3, 7.5,
10.2, 10.3, 10.5, 10.6 and 10.8): 

  

	 	(A)	if the Retention Period is less than three years, the Matching Share Award shall lapse and there shall be no multiple; 

  

	 	(B)	if the Retention Period is at least three years but less than four years, the multiple shall be not more than 2; 

  

	 	(C)	if the Retention Period is at least four years but less than five years, the multiple in sub-Rule (B) above may be increased by 

  

 9 

 not more than 25% (ie, it could increase to a maximum of 2.5), but may not be decreased; 
  

	 	(D)	if the Retention Period is five years or more, the combined multiple arising from the application of sub-Rules (B) and (C) above may be increased by not more than 20% (ie, it could
increase to a maximum of 3), but may not be decreased. 

  

	 	(e)	The Exercise Period applicable to Matching Share Awards will (subject always to Rules 7 and 10): 

  

	 	(i)	be set out in the relevant Award Agreement; 

  

	 	(ii)	commence no earlier than the third anniversary of the relevant Date of Grant; and 

  

	 	(iii)	expire no later than three years thereafter.

	4.2	Each Invitation shall be made by letter (accompanied by the relevant Award Agreement) and shall confirm: 

  

	 	(a)	whether the Award is a Matching Share Award or a Restricted Share Award; 

  

	 	(b)	the Award Price at which the Award will be granted if the Application made in response to that Invitation is accepted; 

  

	 	(c)	in the case of a Matching Share Award, the maximum percentage of Annual Salary, or maximum monetary sum, that may be applied by the Award Holder in the purchase of Committed Shares;

  

	 	(d)	in the case of a Matching Share Award, the maximum multiples applicable to the Award pursuant to sub-paragraphs (B), (C) and (D) of Rule 3.3 (d) (iii); 

  

	 	(e)	the number of Shares in respect of which an Award may be granted; 

  

 10 

	 	(f)	the Exercise Conditions applicable to that Award; 

  

	 	(g)	the Proposed Date of Grant; 

  

	 	(h)	the Acceptance Date; and 

  

	 	(i)	the proposed Grantor of the Award. 

  

	4.3	Each Invitation shall be personal to the Eligible Employee to whom it is made. 

  

	4.4	In respect of any Award, the Invitation Date and the Proposed Date of Grant must fall within the same Financial Year. 

  

	5	Grant of Awards 

  

	5.1	If any Eligible Employee to whom an Invitation is made wishes to accept that Invitation he shall execute an Application and the relevant Award Agreement (undated) in relation to
that Invitation and deliver them to the Company on or before the Acceptance Date. For this purpose an Application and Award Agreement delivered by post shall be treated as having been delivered on the date of posting. 

  

	5.2	As soon as reasonably practicable after the Acceptance Date the Remuneration Committee shall consider the Applications and, if it so decides, may: 

  

	 	(a)	accept the Application and grant an Award pursuant thereto on the Proposed Date of Grant; or 

  

	 	(b)	invite a Trustee to consider the Application and, if that Trustee so decides, to accept the Application and grant an Award pursuant thereto on the Proposed Date of Grant

  
 Provided that no Award shall be granted if the
applicant therefore has ceased to be an Eligible Employee on or before the Proposed Date of Grant. 
  

	5.3	The Directors or (as the case may be) a Trustee may in its absolute discretion treat an Application delivered late as valid unless delivered after the Proposed Date of Grant.

  

	5.4	Following the acceptance of an Application, an Award shall be granted by the Grantor: 

  

	 	(a)	executing the Award Agreement under seal or otherwise in such manner as to 

  

 11 

 take effect in law as a deed; and 
  

	 	(b)	dating that Award Agreement on the Proposed Date of Grant. 

  

	5.5	Within twenty eight days after the grant of an Award by execution of an Award Agreement the Grantor shall deliver a copy, or counterpart, of it to the relevant Award Holder. For the
avoidance of doubt, Award Agreements may be executed in counterpart, in circumstances where one counterpart is executed by each party. 

  

	5.6	Every Award shall be subject to the condition that no Shares shall be issued to an Award Holder pursuant to the exercise of that Award if such issue would be contrary to any
enactment or regulation for the time being in force in the United Kingdom. 

  

	5.7	Invitations may only be issued, and Awards may only be granted, within the period of 42 days commencing: 

  

	 	(a)	on the Date of Adoption; 

  

	 	(b)	on the fourth Dealing Day next following a Date of Announcement; or 

  

	 	(c)	the date on which any statute or any regulation or order made thereunder or any governmental directive for the time being to prevent the grant of Awards shall cease to have effect.

  

	5.8	Notwithstanding Rule 5.7 above the Directors may grant Awards outside the periods specified in Rule 5.7 in circumstances which the Directors in their absolute discretion deem
sufficiently exceptional to justify the grant of Awards at that time. 

  

	5.9	Notwithstanding Rule 4, and the above provisions of this Rule 5, a Grantor may grant an Award unilaterally by issuing an Award Agreement to an Eligible Employee. Provided the
Eligible Employee executes, and returns to the Company, a copy of that Award Agreement within twenty one days of the date on which the Award Agreement is executed by the Grantor, the Invitation Date and Date of Grant of such Award Shares be treated
(for the purposes of these Rules) as the date on which the Award Agreement is executed by the Grantor. An Award may only be granted in this manner if the Remuneration Committee so consents. 

  

	5.10	Each Award shall be personal to the Award Holder to whom it is granted and other 

  

 12 

 than a transfer to the Award Holder’s personal representatives on death shall not be transferable,
assignable or chargeable. Any other purported transfer, assignment, charge, disposal or dealing with the rights and interests of the Award Holder under this Plan shall cause the Award to lapse immediately. 
  

	5.11	For the purpose of Rule 5.10 Awards shall be treated as lapsing in the order in which they were originally granted. 

  

	5.12	In the event of an Award lapsing under Rule 5.10 in part only, the balance of the Award shall continue to be exercisable in accordance with this Plan. 

  

	6	Restrictions on the granting of Awards 

  

	6.1	The aggregate number of Shares which may be issued on the exercise of Awards granted on any day shall not, when added to the aggregate of: 

  

	 	(a)	the total number of Shares issued or remaining issuable in respect of Awards granted under this Plan in the 10 years preceding that day; and 

  

	 	(b)	the total number of Shares issued or remaining issuable in respect of any other Employee Share Scheme adopted by the Company or any Subsidiary or in respect of an Exchange in the 10
years preceding that day, 

  
 exceed such number as
represents 10% of the issued ordinary share capital of the Company immediately prior to that day. 
  

	6.2	On any Invitation Date the aggregate Market Value of Shares which may be acquired on the exercise of any Restricted Share Award in respect of which an Invitation is issued to an
Eligible Employee shall not, when aggregated with the Market Value of any Shares which remain to be acquired on the exercise of Restricted Share Awards granted to the Eligible Employee in question during the Financial Year in which such Invitation
Date falls, exceed 100% of his Annual Salary at such Invitation Date 

  

	6.3	On any Invitation Date the aggregate Market Value of Shares which may be acquired on the exercise of any Restricted Share Award in respect of which an Invitation is issued to an
Eligible Employee shall not, when aggregated with the Market Value of any Shares which remain to be acquired on the exercise of Restricted Share Awards or 

  

 13 

 any other right to acquire Shares granted to the Award Holder in question, during the Financial Year in
which such Invitation Date falls, under: 
  

	 	(a)	this Plan; and 

  

	 	(b)	any other discretionary share option scheme established by the Company or any associated company of the Company (as defined in section 416 of the Taxes Act) before or after this
Plan, 

  
 exceed 200% of his Annual Salary at such
Invitation Date provided that for the purposes of this Rule 6.3 no account shall be taken of Shares acquired, or to be acquired, pursuant to Matching Share Awards. 
  

	6.4	On any Invitation Date the aggregate Market Value of Shares which may be acquired on the exercise of any Matching Share Award in respect of which an Invitation is issued to an
Eligible Employee shall not, when aggregated with the Market Value of any Shares which remain to be acquired on the exercise of Matching Share Awards granted to the Eligible Employee in question during the Financial Year in which such Invitation
Date falls, exceed 45% of his Annual Salary at such Invitation Date. 

  

	6.5	For the purposes of Rules 3.3(a), 6.2, 6.3 and 6.4 on any day (the “relevant date”): 

  

	 	(a)	the Market Value of a Share in relation to which an Award is to be, granted under this Plan shall be such value per share as: 

  

	 	(i)	the Company may consider to be the market value thereof on the day preceding the relevant date and determined in accordance with Part VIII of the Taxation of Chargeable Gains Act
1992; or 

  

	 	(ii)	if such Shares are at that time listed on the London Stock Exchange the average of the middle market quotations of a Share as derived from the London Stock Exchange Daily Official
List on the 3 Dealing Days preceding the relevant date; and 

  

	 	(b)	the Annual Salary of an Award Holder shall be his Relevant Emoluments for the current or preceding Financial Year (whichever of those years gives the greater amount) or, in the case
of an Award Holder who received no Relevant 

  

 14 

 Emoluments throughout the preceding Financial Year, his Relevant Emoluments for the period of 12 months
beginning with the first day during the current Financial Year for which there are Relevant Emoluments. 
  
 BUT PROVIDED THAT if in any Financial Year more than one Award is made to an Award Holder, the Market Value and Annual Salary prevailing as at the
Invitation Date of the first of those Awards shall then apply for all subsequent Awards made to that Award Holder in the same Financial Year. 
  

	6.6	For the purposes of Rule 6.3(b) the Market Value of a Share in relation to which a right to acquire Shares has been granted under this Plan or under any other discretionary share
option scheme established by the Company or any associated Company of the Company shall be the market value of a Share at the date of grant of such right or Award as calculated in accordance with the rules of the scheme under which it was granted.

  

	6.7	If an Award Holder’s Annual Salary comprises either wholly or in part payments in a currency other than pounds sterling (“foreign currency”), for the purpose of
calculating the maximum number of Shares which may be acquired pursuant to the exercise of Awards under this Plan, that foreign currency shall be converted into pounds sterling at the mid-market spot rate for that currency at the close of business
published by the Financial Times for the relevant date, or if this is not a Business Day, the mid-market spot rate for that currency at the close of business published in the Financial Times for the next preceding Business Day.

  

	6.8	In applying the limits contained in Rules 6.1, 6.2, 6.3 and 6.4 no account will be taken of Shares subject to any right, option or Award which, as regards any rights to subscribe
for or acquire such Shares, has lapsed or been released, surrendered or cancelled. 

  

	6.9	No Awards shall in any event be granted more than 10 years after the Date of Adoption. 

  

	6.10	All options and rights to acquire shares granted prior to 26 February 1997 shall be disregarded for the purposes of the limit contained in Rule 6.1. 

  

 15 

	7	Rights to exercise Awards 

  

	7.1	Subject to the provisions of this Rule 7 and Rules 9 and 10 an Award shall be capable of being exercised in accordance with the provisions of Rule 8: 

  

	 	(a)	during its Exercise Period, and 

  

	 	(b)	provided that any relevant Exercise Condition has been satisfied (unless the Award Agreement provides otherwise). 

  

	7.2	No Award may be granted, exercised, released or surrendered at a time when such grant, exercise, release or surrender would either: 

  

	 	(a)	not be in accordance with the “Model Code for Securities Transactions by Directors of Listed Companies” issued by the London Stock Exchange as amended from time to time;
or 

  

	 	(b)	be prevented by any statute or any regulation or order made thereunder or any governmental directive. 

  

	7.3	If an Award Holder ceases to be a director or employee of a Group Member (including by reason of his death), any Awards granted to him under this Plan shall lapse upon such
cessation unless and to the extent that the Grantor, acting on the recommendation of the Remuneration Committee, resolves otherwise (either before or within 30 days after such cessation, or 90 days in the case of death), in which event such Awards
may (and must, if at all) be exercised to the extent permitted by the Grantor within 6 months (or, in the case of cessation by reason of death, 12 months) after his so ceasing. Exercise of an Award pursuant to this Rule 7.3 shall not, if and to the
extent that the Remuneration Committee so resolve, be subject to the satisfaction of any Exercise Conditions. 

  

	7.4	An Award Holder shall not be treated for the purposes of Rule 7.3 above as ceasing to be a director or employee of a Group Member until such time as he is no longer a director or
employee of any Group Member, and a female Award Holder who ceases to be such a director or employee by reason of pregnancy or confinement and who returns to work at the end of the maternity leave period conferred on her by Part VIII of the
Employment Rights Act 1996 or who exercises her right to return to work 

  

 16 

 following maternity absence in the circumstances described in Part VIII of the Employment Rights Act 1996
(or otherwise returns to work if the Directors so determine) before exercising an Award under this Plan shall be treated for those purposes as not having ceased to be such a director or employee. 
  

	7.5	If an Award Holder dies before exercising an Award granted to him under this Plan and at a time when he is either a director or employee of a Group Member or entitled to exercise
the Award by virtue of Rule 7.3 above, the Award may, to the extent permitted under Rule 7.3 (and must, if at all) be exercised by his personal representatives within 12 months after the date of his death. 

  

	7.6	Notwithstanding any other provision of this Plan, an Award granted under this Plan may not be exercised after the expiration of the period of 10 years (or such shorter period as
shall be specified in the Award Agreement) beginning with the Date of Grant. 

  

	8	Exercise of Awards 

  

	8.1	Awards may be exercised in whole or in part. 

  

	8.2	The exercise of any Award granted under this Plan shall be effected by giving notice to the Company (in its own right or as agent for and on behalf of the Grantor) in writing in
such form and manner as the Directors may from time to time prescribe accompanied by the Award Agreement and payment for the total Award Price (if any) for the Shares in respect of which the Award is exercised. The Directors may in their absolute
discretion agree such arrangements as are, in form and substance, satisfactory to them for payment to the Company of the Award Price for the Shares in respect of which the Award is exercised. The date of receipt by the Company of the notice and
payment shall constitute for all purposes the date on which the Award is exercised. 

  

	8.3	Subject to Rules 8.5 and 9, within 30 days after an Award under this Plan has been exercised by any person, the Directors on behalf of the Company shall allot to him (or his
nominee) or, as appropriate, procure the transfer to him (or his nominee) of the number of Shares in respect of which the Award has been validly exercised, provided that, for the avoidance of doubt, where Shares are so allotted or transferred to a
nominee, the beneficial interest in them must vest in the person who exercised the 

  

 17 

 Award. 
  

	8.4	All shares allotted under this Plan shall rank pari passu in all respects with the shares of the same class for the time being in issue save as regards any rights attaching to such
shares by reference to a record date prior to the date of the allotment, and in the case of the transfer of existing shares, the transferee shall not acquire any rights attaching to such shares by reference to a record date prior to the date of the
transfer. 

  

	8.5	The allotment or transfer of any shares under this Plan shall be subject to obtaining any approval or consent mentioned in Rule 14.5 below. 

  

	8.6	In the event of a partial exercise of an Award, the Company shall, within 30 days of the partial exercise: 

  

	 	(a)	Endorse, or procure the endorsement of, onto the Award Agreement a memorandum reflecting the partial exercise of that Award; and 

  

	 	(b)	Deliver, or procure the delivery of, that Award Agreement (as endorsed) to the Award Holder. 

  

	9	Award Tax Liabilities 

  

	9.1	In this Rule 9 “Award Tax Liabilities” means, in relation to an Award, liabilities of the Company or a Group Member or, as the case may be, a Grantor to pay or
account: 

  

	 	(a)	to the Revenue for any amount of income tax or other tax of the United Kingdom or national insurance contributions (including, unless the Company decides otherwise, employer’s
national insurance contributions) of the United Kingdom; and/or 

  

	 	(b)	to any other taxation authority for any other amount of taxation (whether of the United Kingdom or elsewhere) 

  
 arising as a consequence of exercise of the Award or otherwise in relation
to the Award (but to the extent only that payment or reimbursement of any such amount by the Award Holder is permitted by law). 
  

	9.2	The exercise of an Award by an Award Holder shall constitute the agreement and 

  

 18 

 undertaking of the Award Holder with the Company (in its own right and as agent for all Group Members
and, where relevant, the Grantor) that he will forthwith upon written demand from the Company pay to the Company or as the Company may direct an amount equal to all Award Tax Liabilities in relation to that Award and shall also constitute authority
to the Company and each Group Member and, where relevant, the Grantor to deduct any amount so demanded which remains unpaid from payments otherwise payable to the Award Holder, including but not limited to authority to deduct from wages or salary
for the purposes of Part II of the Employment Rights Act 1996. 
  

	9.3	Without prejudice to the generality of Rule 9.2 the Company may as soon as practicable following receipt of the documents and payment referred to in Rule 8.2, notify the Award
Holder in writing of the amount (if any) (“the Notified Sum”) which in its reasonable opinion it estimates the Company or any Group Member or the Grantor will be required to pay to the Revenue and/or the relevant tax authority in
respect of Award Tax Liabilities. Subject as hereafter provided, upon the giving of such a notice the Award Holder shall thereupon be bound and obliged to pay to the Company within seven days thereafter the Notified Sum and any obligation of the
Company to allot or procure the transfer of Shares to the Award Holder pursuant to Rule 8.3 shall be conditional upon receipt by the Company of the Notified Sum. In the event that the Notified Sum proves to be an over-estimate of the sum due the
Company shall repay to the Award Holder, on the date on which there is paid to the Revenue or the relevant tax authority the sum actually so due, that part of the Notified Sum which is not so paid. In the event that the Notified Sum is less than the
aggregate amount which is required to be so paid to the Revenue and/or the relevant tax authority, the Award Holder shall forthwith on demand pay to the Company the balance of the amount so paid. The Directors may in their absolute discretion agree
such arrangements as are, in form and substance, satisfactory to them for payment to the Company of the Notified Sum and any further sum which may become due from the Award Holder as aforesaid in lieu of payment of the Notified Sum.

  

	10	Take-overs, reconstructions and winding-up 

  

	10.1	Rule 10.2 applies if: 

  

 19 

	 	(a)	an Acquiring Company: 

  

	 	(i)	obtains Control of the Company as a result of making: 

  

	 	(A)	a general offer to acquire the whole of the issued ordinary share capital of the Company which is made on a condition such that if it is satisfied the person making the offer will
have Control of the Company, or 

  

	 	(B)	a general offer to acquire all the shares in the Company which are of the same class as the shares which may be acquired by the exercise of Awards granted under this Plan, or

  

	 	(ii)	obtains Control of the Company in pursuance of a compromise or arrangement sanctioned by the court under section 425 of the Companies Act 1985, or 

  

	 	(iii)	becomes bound or entitled to acquire shares in the Company under sections 428 to 430F of that Act; AND 

  

	 	(b)	the Acquiring Company indicates that it shall offer, and does so offer, to release any Award granted under this Plan which has not lapsed (“the Old Award”) in
consideration of the grant to the Award Holder of an award (“the New Award”) which is, in the reasonable opinion of the Remuneration Committee, broadly equivalent to the Old Award but relates to shares in a different company (whether the
Acquiring Company itself or some other company) (an “Exchange Offer”). 

  

	10.2	If this Rule 10.2 applies, each Award shall lapse upon the expiry of the period during which the Exchange Offer is open for acceptance unless and to the extent that, on or before
the expiry of that period, the Award Holder exercises that Award or irrevocably accepts the Exchange Offer in respect of it. 

  

	10.3	If: 

  

	 	(a)	any person obtains Control of the Company (within the meaning of section 840 of the Taxes Act) as a result of making a general offer to acquire shares in the

  

 20 

 Company, or having obtained such Control makes such an offer, and 
  

	 	(b)	Rule 10.2 does not apply 

  
 the Directors shall within 7 days of becoming aware thereof notify every Award Holder (or as the case may be his personal representative) thereof and,
subject to compliance with Rules 7.3, 7.5 and 7.8, all Awards granted under this Plan shall, to the extent they are not exercised, lapse on the expiry of six months (or such longer period as the Grantor, acting solely on the recommendation of the
Remuneration Committee, may permit) of such notification. The Grantor of any Award may (acting on the recommendation of the Remuneration Committee) allow that Award to be exercised during this period notwithstanding that such Award would not
otherwise be capable of exercise (in whole or in part) under these Rules, in which event the exercise of such Award shall not (if and to the extent that the Remuneration Committee so resolves) be subject to the satisfaction of any Exercise
Conditions. 
  

	10.4	For the purposes of Rules 10.1 and 10.3 above, a person shall be deemed to have obtained Control of the Company if he and others acting in concert (as defined by the City Code on
Takeovers and Mergers) with him have together obtained Control of it. 

  

	10.5	If: 

  

	 	(a)	any application is made to the Court under section 425(1) of the Companies Act 1985 to order a meeting in relation to a proposed compromise or arrangement for the purposes of or in
connection with a scheme for the reconstruction of the Company or its amalgamation with any other company or companies; and 

  

	 	(b)	Rule 10.2 does not apply 

  
 the Grantor of an Award, acting on the recommendation of the Remuneration Committee, may permit any Award granted under this Plan, subject to Rules 7.3,
7.5 and 7.8, to be exercised (notwithstanding that it would not otherwise be capable of exercise) until the time of the meeting, such exercise being conditional upon the Court sanctioning such compromise or arrangement, and in which event the
exercise of such Awards shall not (if and to the extent that the Remuneration Committee so resolves) be subject to the satisfaction of any Exercise Conditions. 
  

 21 

	10.6	If: 

  

	 	(a)	any person becomes bound or entitled to acquire shares in the Company under sections 428 to 430F of the Companies Act 1985; and 

  

	 	(b)	Rule 10.2 does not apply 

  
 the Directors shall forthwith notify every Award Holder (or as the case may be his personal representatives) thereof and all Awards granted under this
Plan shall to the extent they are not exercised, lapse on the expiry of one month of such notification. The Grantor of any Award may (acting on the recommendation of the Remuneration Committee) allow that Award to be exercised during this one month
period notwithstanding that such Award would not otherwise be capable of exercise (in whole or in part) under these Rules, in which event the exercise of such Award shall not (if and to the extent that the Remuneration Committee so resolves) be
subject to the satisfaction of any Exercise Conditions. 
  

	10.7	If the Company passes a resolution for voluntary winding up, or if an order is made for the compulsory winding up of the Company, the Directors shall forthwith notify every Award
Holder (or as the case may be his personal representatives) thereof and any Awards granted under this Plan shall, subject to Rules 7.3, 7.5,7.8, 10.8, 10.9 and 10.10, be capable of exercise within one month of such notification, but to the extent
that it is not exercised within that period shall (notwithstanding any other provision of this Plan lapse on the expiration thereof. Exercise of an Award pursuant to this Rule 10.7 shall not be subject to the satisfaction of any Exercise Conditions.

  

	10.8	If an Award Holder exercises an Award before the third anniversary of the Date of Grant of that Award, then he may exercise that Award pursuant to Rule 10.7 only in respect of such
number of Shares as is calculated by reference to the following formula: 

  
 A x B 
  
 156 
  
 where: 
  

 22 

 “A” is the number of complete weeks since the Date of Grant of the Award up to the date of
such resolution or order; and 
  
 “B” is: 

 

	 	(i)	in the case of a Restricted Share Award, the number of Shares comprised in the Award; and 

  

	 	(ii)	in the case of a Matching Share Award, the number of Committed Shares held by the Award Holder at the date of such resolution or order multiplied by the highest multiple stipulated,
on the grant of that Award, under Rule 3.3 (d) (iii) (B) 

  
 The Award shall lapse in respect of the balance of the Shares comprised in it. 
  

	10.9	If a Matching Share Award is exercised pursuant to Rule 10.7 on or after the third anniversary, but before the fourth anniversary, of the Date of Grant, the number of Shares in
respect of which that Award may be exercised shall be increased by a number of Shares equal to the number of Committed Shares held by the Award Holder at the date of such resolution or order multiplied by a multiple calculated in accordance with the
following formula: 

  
 C x D 
  
 52 
  
 where: 
  
 “C” is the number of complete weeks since the third anniversary of the Date of Grant of the Award up to the date of such resolution or order;
and 
  
 “D” is the highest multiple stipulated, on the
grant of that Award, under Rule 3.3 (d) (iii) (C) 
  
 The Award
shall lapse in respect of the balance of the Shares comprised in it. 
  

	10.10	If a Matching Share Award is exercised pursuant to Rule 10.7 on or after the fourth anniversary, but before the fifth anniversary, of the Date of Grant, the number of Shares in
respect of which that Award may be exercised shall be increased by a 

  

 23 

 number of Shares equal to the number of Committed Shares held by the Award Holder at the date of such
resolution or order multiplied by a multiple calculated in accordance with the following formula: 
  
 Y x Z 
  
 52 
  
 where: 
  
 “Y” is the number of complete weeks since the fourth anniversary of the Date of Grant of the Award up to the date of such resolution or order;
and 
  
 “Z” is the highest multiple stipulated, on the
grant of that Award, under Rule 3.3 (d) (iii) (D) 
  
 The Award
shall lapse in respect of the balance of the Shares comprised in it. 
  

	11	Adjustment of Awards for variation of share capital 

  

	11.1	Subject to Rules 11.3 and 11.4 below, on the occurrence of an Issue or Re-organisation the Grantor of an Award, with the approval of the Remuneration Committee, may make such
adjustment to that Award as it considers appropriate under Rule 11.2. 

  

	11.2	An adjustment made under this sub-rule may be to one or more of the following: 

  

	 	(a)	the number of Shares in respect of which any Award granted under this Plan may be exercised; 

  

	 	(b)	the Award Price; and 

  

	 	(c)	where any such Award has been exercised but no Shares have been allotted or transferred pursuant to such exercise, the number of Shares which may be so allotted or transferred and
the price at which they may be acquired. 

  

	11.3	Except in the case of a capitalisation issue, no adjustment under Rule 11.2 above shall be made without the prior confirmation in writing by the Auditors that it is in their opinion
fair and reasonable. 

  

 24 

	11.4	An adjustment under Rule 11.2 above may not have the effect of reducing the price at which Shares may be acquired by the exercise of an Award to less than their nominal value.

  

	11.5	As soon as reasonably practicable after making any adjustment under Rule 11.2 above, the Company (in its own right or as agent for the Grantor) shall give notice thereof in writing
or in electronic form to any Award Holders affected thereby. 

  

	12	Expenses 

  

	12.1	Any expenses of the Company involved in any issue or transfer of Shares in the name of any Award Holder or his personal representative(s) or nominee(s) shall be payable by the
Company.
