 Ladies and Gentlemen: 
  
 Cambridge Display Technology Limited (the “Company”) hereby agrees to retain you, Kelso & Company, L.P.
(“Kelso”), to provide consulting and advisory services to the Company commencing on the date hereof for a term ending on the date on which Kelso and its affiliates cease to own any shares of common stock of the Company. Such services may
include such consulting and advisory services in the ordinary course of business as the Company may reasonably request. 
  
 If Kelso or any of its affiliates or designees (the “Kelso Group”) provides consulting or advisory services specifically requested by the
Company out of the ordinary course of business to the Company or any of its affiliates on one or more occasions after the date hereof, then, in each such case, the Company and Kelso will negotiate in good faith to effect a mutually acceptable
advisory fee. The Company will also reimburse Kelso promptly for the Kelso Group’s out-of-pocket costs and expenses incurred in connection with the investment by the Kelso Group in CDT Acquisition Corp. (“CDT Acquisition”) and the
performance of Kelso’s duties hereunder, but excluding in any case the fees, costs or expenses of any consultants to the Kelso Group. Any arrangements for the payment of such fees, costs or expenses of consultants will be handled under separate
agreements between the Company and Kelso. 
  
 The Company will
indemnify Kelso and its affiliates, and their respective officers, directors, employees, agents and control persons (as such term is used in the Securities Act of 1933, as amended, and the rules and regulations thereunder) to the full extent lawful
against any and all claims, losses and expenses as incurred (including all reasonable fees and disbursements of any such indemnitee’s counsel and other out-of-pocket expenses incurred in connection with the investigation of and preparation for
any such pending or threatened claims and any litigation or other proceedings arising therefrom) arising in connection with such indemnitee’s investment in CDT Acquisition or 

 out of any services rendered by Kelso hereunder or any such indemnitee being a controlling person of the Company or any
of its subsidiaries, provided, however, there shall be excluded from such indemnification any such claim, loss or expense that is based upon any action or failure to act by such indemnitee that is found in a final judicial
determination to constitute gross negligence or intentional misconduct on such indemnitee’s part. The Company will advance costs and expenses, including attorney’s fees, incurred by any such indemnitee in defending any such claim in
advance of the final disposition of such claim upon receipt of an undertaking by or on behalf of such indemnitee to repay amounts so advanced if it shall ultimately be determined that such indemnitee is not entitled to be indemnified by the Company
pursuant to this Agreement. 
  
 The Company’s obligations set
forth in this Agreement shall survive the termination of Kelso’s services pursuant to the first paragraph of this Agreement. 
  
 This agreement shall be governed by the laws of the State of New York. 
  
 If you are in agreement with the foregoing, kindly so indicate by signing a counterpart of this letter, whereupon it will

(either the Opsys UK Call Option or the Opsys UK Put Option) (the “Opsys UK Option”) on the exercise of which CDT shall purchase and Opsys shall sell all the issued shares of Opsys UK other than the Opsys UK Subscription Shares
acquired by CDT hereunder and referred to in sub-clause 2.1. In further consideration for the grant of the Opsys UK Call Option, CDT shall pay an option grant price of $500,000 in cash to Opsys on the date of this agreement.

  

 13 

	3.2	The Opsys UK Put Option may be exercised by Opsys by 60 days prior written notice to CDT at any time following Completion subject to and conditional upon Opsys filing jointly with
Opsys UK the election referred to in sub-clause 3.4 and conditional on the Completion of the subscription referred to in sub-clause 2.1 above. 

  

	3.3	At any time following Completion, the Opsys UK Call Option shall be automatically exercised immediately prior to an Insolvency Event of Opsys and otherwise the Opsys UK Call Option
may be exercised by CDT by giving 90 days prior written notice to Opsys on any of the following circumstances: 

  

	 	A.	if there is an Initial Public Offering of CDT; 

  

	 	B.	if there is a Sale of CDT, where the consideration on sale payable to Opsys thereunder will be liquid or a sufficient proportion will be liquid to allow Opsys to pay the 179 Charge
payable (if any) ; 

  

	 	C.	at any time on or after the sixth anniversary of the effective date of the Hive Down Reorganisation; or 

  

	 	D.	if the 179 Charge becomes payable by Opsys UK, 

  
 where in (A) and (B) above such notice shall expire no earlier than the first anniversary of the date of this agreement. 
  

	3.4	If any 179 Charge becomes payable by Opsys UK or the Opsys UK Option is exercised, Opsys and Opsys UK shall and CDT and Opsys shall procure that Opsys UK shall enter into and submit
to the Inland Revenue a joint tax election under Section 179A TCGA 1992 with the intention of ensuring that any 179 Charge is assumed by and falls upon Opsys and not on Opsys UK (the “179 Election”). 

  

	3.5	Subject to sub-clause 3.6 the exercise price payable by CDT on exercise of the Opsys UK Option, or an exercise of the Opsys Option referred to in sub-clause 9.1 shall
be 1,326,837 as adjusted in accordance with sub-clause 10 (Dilution and Reorganisation), sub-clauses 16.7 and 16.8 and sub-clauses 16.15 and 16.16 (Warranties and Covenants) (the “Option Exercise Price”).

  

	3.6	If the 179 Charge falls upon Opsys UK, the Option Exercise Price payable to Opsys on exercise of the Opsys UK Option shall be 464,396 CDT Shares as adjusted in accordance with
sub-clause 10 (Dilution and Reorganisation) and sub clauses 16.7, 16.8, 16.15 and 16.16 (Warranties and Covenants). 

  

	3.7	Subject to sub-clauses 3.9 and 3.10 on the Option Exercise Date CDT shall issue such number of CDT Shares and shall deliver to Opsys certificates 

  

 14 

 representing the Option Exercise Price registered in the name of Opsys and Opsys shall deliver to CDT
duly executed stock transfer forms relating to the Opsys UK Option Shares in the name of CDT (or as it may direct) together with Opsys UK share certificates relating to such shares. Opsys acknowledges that from the Option Exercise Date until such
time as the Opsys UK Option Shares have been registered in the register of members of Opsys UK in the name of CDT (or as it may direct), Opsys will hold such shares registered in its name as nominee for CDT and its nominees and shall exercise all
voting rights available in respect of such shares in accordance with the directions of CDT or its nominees. If Opsys is in breach of the undertakings contained in this sub-clause, it irrevocably authorizes CDT to appoint a representative of CDT to
execute all documents which CDT or its nominees may reasonably require and which may be necessary to enable CDT to attend and vote at general meetings of Opsys UK and to do anything necessary to give effect to the rights contained in this
sub-clause. 
  

	3.8	CDT shall not be obliged to complete the purchase of any of the Opsys UK Option Shares pursuant to an Opsys UK Option unless Opsys completes the sale of all of such shares
simultaneously, but completion of the purchase of some such shares shall not effect the rights of CDT with respect to its rights to the other shares. 

  

	3.9	If the Opsys UK Option is exercised within twelve months of the Completion Date, (i) CDT will make the payment of the Option Exercise Price less such number of CDT Shares at a
deemed value of $16.15 per share as most nearly equals but does not exceed the amount by which the maximum liability cap of $5 million exceeds the aggregate amount of any claims made by CDT or CDT UK hereunder which have resulted in a reduction in
the Option Exercise Price in accordance with this agreement (the “Retained Shares”) and (ii) upon the first anniversary of the Completion Date CDT shall issue such number of Retained Shares to Opsys less that number of CDT Shares at
a deemed value of $16.15 per share as most nearly equals but does not exceed the amount of any outstanding claim by CDT or CDT UK hereunder pending the resolution of such claim and shall deliver to Opsys certificates representing the number of
Retained Shares so issued and registered in the name of Opsys. To the extent that any such claim is not eventually substantiated in favor of CDT, CDT will issue CDT Shares at the value of $16.15 as most equals but does not exceed the unsubstantiated
amount of such claim and shall deliver to Opsys certificates representing the number of Retained Shares so issued and registered in the name of Opsys. At any time, Opsys may at its discretion replace the Retained Shares with cash at a replacement
value of $16.15 per CDT Share. 

  

	3.10	If the Opsys UK Option is exercised then subject to sub-clauses 3.6 and 3.9 CDT shall initially issue to Opsys such number of CDT Shares referred to in sub-clause 3.6
as adjusted therein, and until such time as (A)(i) the Inland Revenue have accepted the joint election submitted in accordance with sub- 

  

 15 

 clause 3.4; and (ii) the 179 Charge has been discharged in full by Opsys, or (B) (i) the Inland
Revenue have accepted the joint election submitted in accordance with sub-clause 3.4; and (ii) the 179 Charge has not been discharged in full by the due date, CDT shall withhold the balance of the Option Exercise Price otherwise payable under
sub-clause 3.5 (“Withheld Shares”). In the case of (A) above, on the date on which the Inland Revenue confirms that: (i) it has accepted the joint election; and (ii) the 179 Charge has been discharged in full by Opsys, the
Withheld Shares shall be issued to Opsys and CDT shall deliver to Opsys certificates representing such Withheld Shares, registered in the name of Opsys. In the case of (B) above, CDT shall use its reasonable efforts to sell on behalf of Opsys such
number of the Withheld Shares (at a price per share to be agreed with Opsys in its sole discretion) for an aggregate cash consideration as is most nearly equal to but is not less than the amount of 179 Charge and on receipt of such sale
consideration (after tax) to discharge the 179 Charge on behalf of Opsys and issue the balance of such Withheld Shares to Opsys at such time together with corresponding certificates representing such Shares registered in the name of Opsys. If the
Inland Revenue does not accept the election or the election is otherwise invalid or ineffective or the 179 Charge is not discharged in full by Opsys or by CDT on behalf of Opsys pursuant to this sub-clause 3.10, the Withheld Shares shall not
be issued to Opsys and the Option Exercise Price shall be as set out in sub-clause 3.6. At any time, Opsys may at its discretion replace the Withheld Shares with cash at a replacement value of $16.15 per CDT Share. 
  

	3.11	Once given, the notice of exercise of the Opsys UK Option is irrevocable provided that the Opsys UK Option shall automatically lapse and have no further force or effect in the
circumstances of CDT suffering an Insolvency Event. 

  

	3.12	On completion of a sale of Opsys UK Option Shares pursuant to this Opsys UK Option, the option in clause 9 (Opsys Limited Option) shall lapse and have no further force and
effect. 

  

	3.13	Subject to sub-clause 3.14, if a receiver (including an administrative receiver), liquidator, trustee, administrator, custodian or similar official is appointed in any
jurisdiction in respect of the whole or any material part of the business or assets of Opsys UK, CDT shall pay the Option Exercise Price to Opsys (and shall indemnify Opsys in respect of any tax payable by Opsys thereon) provided that such payment
shall not be subject to sub-clauses 3.6 and 3.10 nor shall there be any indemnity from the Opsys Shareholders or the Warrantors in respect of the 179 Charge. 

  

	3.14	CDT shall not be obliged to perform its obligations under sub-clause 3.13 if the appointment of such receiver, liquidator, trustee, administrator, custodian or similar
official was caused by circumstances constituting a breach by the Warrantors or Opsys of any Warranty or agreement referred to herein. 

  

 16 

	3.15	Any Retained Shares which relate to a claim of CDT which has been withdrawn or represent an excess of the amount of a settlement of any claim by CDT shall be issued to Opsys and CDT
shall deliver to Opsys certificates representing the number of such Retained Shares so issued and registered in the name of Opsys. 

  

	3.16	If Opsys receives any payments in the form of return on capital or otherwise from any such insolvency practitioner or official referred to in clause 3.13, such payment shall
be paid by the Opsys Shareholders to CDT. 

  

	4.	Conditions to Subscription 

  

	4.1	The subscription obligations of CDT hereunder are in all respects conditional upon those matters (the “Conditions”) listed in Schedule 1 (Conditions to

	4.3	CDT may waive in whole or in part all or any of the Conditions or extend the period in which the Conditions are to be satisfied.

	4.6	If: 

  

	 	(a)	any fact which would prevent any of the Conditions from being satisfied on the Completion Date (whether it does so because of any disclosure made under sub-clause 4.4 or not)
comes to the knowledge of CDT where such fact is not reasonably capable of remedy prior to the Completion Date to the effect that such conditions would then be satisfied before Completion; or 

  

	 	(b)	any of the conditions is not fulfilled (notwithstanding the required reasonable endeavours in sub-clause 4.2) or waived by CDT by the Long Stop Date,

  
 the Opsys UK Option and the Opsys Option shall
lapse and CDT may terminate this agreement by notice in writing to Opsys. 
  

 17 

	4.7	If the agreement is terminated in accordance with sub-clause 4.6, all obligations of the parties under this agreement shall end except those expressly stated to continue

	 	(b)	make any alteration to the memorandum and articles of association of Opsys UK (other than in respect of a change of name) or pass any resolution for winding-up;

  

	 	(c)	allot, issue, redeem or purchase any shares or securities or grant to any person any option or right to call for the issue of any shares or securities in Opsys UK or increase or
reduce the authorized share capital or reorganize the share capital of Opsys UK in any way; 

  

 21 

	 	(d)	make or declare any dividend or other distribution in respect of the issued share capital of Opsys UK; 

  

	 	(e)	create or acquire any unincorporated business or enter into partnership or joint venture with any other person; 

  

	 	(f)	subscribe for or otherwise acquire any interest (whether on its own behalf or as nominee) in the share capital or instruments convertible into the share capital of any other company
or other body corporate or entity or make any other investment in the same; or 

  

	 	(g)	create or allow to come into being any security interest upon any part of its property or assets or uncalled capital or create or issue any credit or issue any debenture or
debenture stock or obtain any advance or credit in any form other than normal trade credit. 

  

	8.4	Opsys shall not transfer, sell, assign, renounce or otherwise create or dispose of any interest (including a security interest) in or over any of its shares in Opsys UK except in
accordance with the provisions of this agreement. 

  

	8.5	Each of CDT and Opsys shall exercise its powers in relation to Opsys UK to procure so far as by the exercise of such power they can so procure and Opsys UK undertakes to each of CDT
and Opsys that (subject to any requirement of law) unless CDT and Opsys otherwise agree in writing insofar as Opsys UK has profits available for distribution, all dividends in respect of the issued share capital of Opsys UK shall be paid strictly in
accordance with the articles of association of Opsys UK and this agreement. 

  

	8.6	The rights and obligations of the parties under this clause 8 shall terminate with immediate effect on completion of the Opsys UK Option. 

  

	8.7	Each of CDT and Opsys shall exercise its powers in relation to Opsys UK to procure so far as by the exercise of such power they can procure that on request by CDT they shall vote
their shares in Opsys UK to change the name of Opsys UK to such name as CDT requests (subject to any requirement of law). 

  

	9.	Opsys Limited Option. 

  

	9.1	CDT hereby grants a put option (the “Opsys Option”) to the Opsys Shareholders on the exercise of which CDT undertakes to Opsys (for the benefit of the Opsys
Shareholders) to purchase the whole of the Opsys Shares. 

  

	9.2	The Opsys Option shall be exercised by Opsys (on behalf of the Opsys Shareholders), by giving notice (the “Notice Date”) in writing to CDT at any time following the
Completion Date. Once exercised by Opsys, the Opsys Option shall be irrevocable by Opsys or the Opsys Shareholders provided that the Opsys Option shall automatically lapse and have no further force or effect in the event that CDT suffers an
Insolvency Event. 

  

 22 

	9.3	The exercise of the Opsys Option shall be conditional on Completion. 

  

	9.4	CDT’s obligation to purchase the Opsys Shares pursuant to sub-clause 9.1 shall be conditional on the matters listed in sub-clauses 9.15 and 9.17 and further
conditional on either CDT (acting reasonably) being satisfied that; or the Expert Report (as defined below in sub-clause 9.7(C)) or Expert’s Second Report (as defined below in sub-clause 9.11(B)) concluding that:

  

	 	A.	the issued share capital of Opsys UK comprises the only material asset of Opsys; and 

  

	 	B.	no criminal liability has been identified which arises from the past actions or omissions of the directors or employees of Opsys and which results or may result in future directors
or employees of Opsys incurring criminal liability; and 

  

	 	C.	the aggregate liabilities (including the maximum contingent liability under any contingent liabilities and including for the avoidance of doubt the maximum contingent liability for
past breaches of pensions law and regulations but excluding liabilities to CDT, CDT UK or Opsys UK arising under this agreement) of the Opsys Group (other than Opsys UK and its subsidiaries from time to time) do not exceed $1.25 million and such
liabilities can be adequately covered by the Opsys Shareholders on the Opsys Share Completion Date by means of offering CDT compensation or warranty or indemnity cover to be satisfied at the discretion of the Opsys Shareholders in cash or by means
of a reduction to the Option Exercise Price at a deemed value of $16.15 per CDT Share to the satisfaction of CDT acting reasonably. 

  

	9.5	If CDT (acting reasonably) is not satisfied that all of the conditions in sub-clause 9.4 have been met, CDT shall so notify Opsys in writing within twenty Business Days of
the Notice Date. 

  

	9.6	On receipt of such notice Opsys shall have ten Business Days in which to give written notice to CDT that an independent review of the liabilities and assets of Opsys should be
undertaken pursuant to and in accordance with sub-clauses 9.7 to 9.10. Failure to make such a request within this period shall cause the Opsys Option to lapse and have no further force or effect. 

  

	9.7	If Opsys requests such an independent review under sub-clause 9.6, as soon as reasonably practicable thereafter, Opsys and CDT undertake to jointly appoint the law firm
Clifford Chance or another mutually acceptable independent international law firm (the “Expert”) reasonably agreed between CDT and Opsys to: 

  

	 	A.	review the Opsys Disclosure Letter and the documents referred to therein together with the Warranties in part 2 of Schedule 3 which are relevant to the disclosures;

  

 23 

	 	B.	make further enquiries of the Warrantors and any continuing directors of Opsys at that time concerning (i) the circumstances identified in the Opsys Disclosure Letter; (ii) any
changes in such circumstances or any changes to Opsys or the business and affairs of Opsys since the Hive Down Date; (iii) the liabilities (including contingent liabilities) in the Opsys Group (other than in Opsys UK and its subsidiaries from time
to time) since the Hive Down Date; and (iv) the assets in Opsys; and review the documentation referred to in responses to such enquiries; and 

  

	 	C.	produce a written report (the “Expert Report”) identifying in reasonable detail the investigation it has carried out; the documents it has reviewed and the
enquiries it made in the review. The Expert Report shall list the assets and liabilities identified as a result of the review and shall contain an assessment of the nature of each liability and the maximum financial costs related to each. The Expert
Report shall also either confirm that the conditions in sub-clause 9.4 have been fulfilled or it shall identify the circumstances accounting for non fulfillment of such conditions. Except as set out in sub-clause 9.11 B., the Expert
Report shall be final and binding on CDT, Opsys and the Opsys Shareholders (in the absence of manifest error). Any challenge to the Expert Report on the basis of manifest error shall be made within 20 Business Days of the date of publication of the
Expert Report. 

  

	9.8	The Expert shall address and deliver the Expert Report to and allow it to be relied on by both CDT and Opsys (on behalf of the Opsys Shareholders). 

  

	9.9	The Expert shall have the right to request the assistance of an independent accounting firm reasonably acceptable to both CDT and Opsys in order to assist it in classifying and
quantifying existing liabilities (current and contingent). 

  

	9.10	Both CDT and Opsys shall have the right to make at least one oral and written submission to the Expert. 

  

	9.11	If: 

  

	 	A.	(i) the Expert confirms that; or (ii) CDT confirms in writing that the conditions in sub-clause 9.4 are satisfied then CDT shall proceed with the acquisition of the Opsys
Shares in accordance with this clause 9 provided that CDT shall reduce from the Option Exercise Price: such number of CDT Shares at a value of $16.15 per share as most nearly 

  

 24 

 equals but does not exceed the value of the aggregate current liabilities (which for the avoidance of
doubt shall not include contingent liabilities) so agreed by CDT and Opsys or identified by the Expert in the Expert Report, and shall withhold CDT Shares from the Option Exercise Price in accordance with sub-clause 9.12. 
  

	 	B.	the Expert Report states that the conditions referred to in sub-clause 9.4 have not been fulfilled or otherwise identifies circumstances accounting for the non fulfillment of
such conditions Opsys may attempt to satisfy the conditions and demonstrate to CDT that they have been satisfied. Thereafter, if CDT (acting reasonably) is not satisfied that the conditions have been satisfied, CDT shall promptly provide Opsys with
reasonable details of why it believes that the conditions in sub-clause 9.4 remain to be satisfied. Opsys shall have the right prior to the expiry of a period of six calendar months from the date of the Experts Report to request a second
independent review, after which a second written report (the “Expert’s Second Report”) will be produced, in accordance with sub-clauses 9.6 to 9.13 inclusive (mutatis mutandis) provided that this sub-clause 9.11 B
shall not apply to any such second review. 

  

	9.12	CDT shall withhold from the Option Exercise Price, until the earlier of the date on which any contingent liability shall crystalise or the expiry of the applicable statute of
limitations, such number of CDT Shares as most nearly equals but does not exceed the amount of all contingent liabilities so identified by the Expert or agreed by Opsys and CDT at a value of $16.15 per CDT Share. If the contingent liability ceases
to exist or fails to crystalize before the expiry of the relevant statute of limitations CDT shall stop withholding such CDT Shares from the Opsys Shareholders and shall issue them in accordance with sub-clause 9.15 mutatis mutandis. If the
contingent liability crystalizes before the expiry of the relevant statute of limitations, CDT shall reduce the number of withheld shares payable on expiry of the statute of limitations by such number of CDT Shares at a value of $16.15 per share as
most nearly equals but does not exceed the amount of such contingent liability. At any time, Opsys may at its discretion replace such withheld shares with cash at a replacement value of $16.15 per CDT Share. If CDT shall have withheld CDT Shares
under this sub-clause 9.12 for a period of two years, CDT and the Warrantors shall meet and discuss a possible reasonable earlier release date for such CDT Shares. If the parties fail to reach a reasonable agreement on the appropriate release
date they agree to seek mediation of such dispute. 

  

	9.13	Opsys agrees to pay the full costs of the Expert’s reviews referred to in sub-clauses 9.7 and 9.11 (B), unless the Expert confirms in the relevant Expert report that the
conditions in sub-clause 9.4 are satisfied in which case CDT will pay the costs of such review on which the relevant Expert report was based. 

  

 25 

	9.14	Subject to sub-clauses 9.11, 9.12 and 9.16, the exercise price payable to the Opsys Shareholders on exercise of the Opsys Option shall be the price referred to in
sub-clause 3.5 (Opsys UK Options) as adjusted therein provided that in this circumstance the payment of such price shall not be subject to sub-clause 3.6 (Opsys UK Options) nor shall Opsys be required to file an election as required in
sub-clause 3.4. 

  

	9.15	Subject to sub-clause 9.16 and conditional on the matters listed in A and B below: 

  

	 	A.	Opsys shall deliver to CDT (i) stock transfer forms duly executed by the Opsys Shareholders relating to the whole of the Opsys Shares in the name of CDT (or as it may direct); (ii)
the Opsys Share certificates relating to such shares; (iii) the Joinder Agreement and the Investor Rights Agreement in each case duly executed by the Opsys Shareholders; (iv) a duly executed power of attorney and acknowledgement that from the date
of completion of the sale of the Opsys Shares to CDT pursuant to the Opsys Option (the “Opsys Share Completion Date “) until such time as the Opsys Shares have been registered in the register of members of Opsys in the name of CDT,
the Opsys Shareholders will hold such shares registered in their names on trust for and as nominees for CDT and its nominees and shall exercise all voting rights available in respect of such shares in accordance with the directions of CDT or its
nominees; 

  

	 	B.	Subject to sub-clause 17.9 if the Warrantors warrant, and in respect of (w) and (x) only, Opsys Shareholders also warrant in each case, on the Opsys Share Completion Date (w)
that they have the full capacity and authority to sell the whole of the Opsys Shares and that all such shares are sold with full title guarantee, (x) in the terms of the side letter required for US security law purposes and containing the warranties
set out in Schedule 11 (Opsys Shareholder warranties) in agreed form, (y) Opsys has fewer than fifty shareholders in total who together hold the whole of Opsys Shares, and (z) that the Expert Report (and the Expert’s Second Report, as
the case may be) materially is accurate and there are no other facts which having been omitted, make any statement or conclusion in the Expert Report (and the Expert’s Second Report, as the case may be) misleading; 

  
 then subject to the terms of this clause 9, CDT shall deliver to
Opsys, certificates representing the Option Exercise Price registered in the names of the Opsys Shareholders and procure that the parties other than the Opsys Shareholders enter into the Joinder Agreement and the Investor Rights Agreement..

  

	9.16	If the Opsys Option is exercised and CDT acquires the Opsys Shares within twelve months of the Completion Date, CDT shall make the payment of the 

  

 26 

 Option Exercise Price referred to in sub-clause 9.14 less such number of CDT Shares at a deemed
value of $16.15 per share as most nearly equals but does not exceed the amount by which $5 million exceeds the amount of any warranty claims made by CDT hereunder which have resulted in a reduction in the Option Exercise Price in accordance with
this agreement (“Retained Shares”). At the expiry of the twelve month period referred to above, CDT shall issue such number of Retained Shares to the Opsys Shareholders less that number of CDT Shares at a deemed value of $16.15 per
share as most nearly equals but does not exceed the amount of any outstanding claim by CDT hereunder pending resolution of such claim, together with certificates representing such CDT Shares issued and registered in the names of the Opsys
Shareholders. To the extent that such claim is not eventually substantiated in favor of CDT, CDT will issue CDT Shares at the value of $16.15 as most equals but does not exceed the unsubstantiated amount of such claim. At any time, Opsys may at its
discretion replace the Retained Shares with cash at a replacement value of $16.15 per CDT Share. 
  

	9.17	CDT shall not be obliged to complete the purchase of the Opsys Shares unless the Opsys Shareholders complete the sale of all the Opsys Shares simultaneously. If CDT elects to
purchase some of Opsys Shares, CDT shall purchase the remaining Opsys Shares, within two Business Days of such shares becoming available, provided the: 

  

	 	A.	Opsys Shareholders who have not sold their Opsys Shares to CDT make their shares available for sale within six months of CDT’s initial purchase; and 

 

	 	B.	conditions set out in sub-clauses 9.2, 9.3, 9.4, 9.15 and 9.17 are satisfied. 

  

	9.18	If any of Opsys Shareholders are in breach of the undertakings contained in sub-clause 9.15 A(v), it irrevocably authorizes CDT to appoint a representative of CDT to execute
all documents which CDT or its nominees may reasonably require and which may be necessary to enable CDT to attend and vote at general meetings of Opsys and to take any measures necessary to give effect to the rights contained in sub-clause
9.16. 

  

	9.19	For the avoidance of doubt, on the completion of a sale of Opsys Shares pursuant to this clause 9, the options in clause 3 (Opsys UK Options) shall lapse and have no
further force and effect. 

  

	9.20	If the Expert’s Second Report is unable to make the confirmation that the conditions in sub-clause 9.4 are satisfied, CDT shall not be required to purchase the Opsys
Shares hereunder and the Opsys Option shall lapse and have no further force and effect. 

  

	9.21	For the avoidance of doubt, the Opsys Option shall be exercised only once. 

  

 27 

	10.	Dilution and Reorganisation 

  

	10.1	At any time during the period commencing on the date of this agreement and terminating on the Business Day next following the date on which CDT has issued equity or recorded
revenues from sale of licences, intellectual property rights bringing in new funds aggregating $25 million since the Completion Date (excluding the $5 million investment by Toppan referred to in paragraph 3 of Schedule 1 (Conditions to
Completion)), if CDT issues new CDT Shares at a price lower than $16.15, then: 

  

	 	(a)	the number of CDT Shares comprising the Option Exercise Price in sub-clauses 3.5 and 3.6 (Opsys UK Options); 

  

	 	(b)	the number of CDT Shares held in sub-clause 3.10 (Opsys UK Options); and 

  

	 	(c)	the number of CDT Shares held in sub-clause 9.16 (Opsys Options) 

  
 shall be multiplied by a ratio equal to $16.15 divided by the new share price. 
  

	10.2	The number of CDT Shares issued in satisfaction of the exercise price referred to in sub-clauses 3.5 and 3.6 (Opsys UK Options) and the deemed value of CDT Shares hereunder
shall be adjusted by the parties hereto as appropriate and necessary to reflect any bonus issue, share split share combination or recapitalization, merger, consolidation exchange of shares, dissolution or liquidation of CDT which takes place after
the Completion Date to the extent that such adjustment would have been reflected in this agreement in the event that such capital adjustment had taken place prior to the date hereof. 

  

	10.3	Any dispute or difference among the parties hereto as to the effect of any capital adjustment on this agreement including the number of CDT Shares to be paid on satisfaction of the
exercise price, which is not settled within ten Business Days of notice from one party to the other, shall be referred for final settlement to an independent firm of accountants reasonably acceptable to the parties or if the parties fail to agree on
an accountant, then to a firm of accountants chosen by the President from time to time of the Institute of Chartered Accountants (the “Accountant”). The Accountant shall be entitled to call for and inspect such documents as they may
consider necessary. In making their determination, the Accountant shall act as experts and not arbitrators. Their determination (in the absence of manifest error appearing within 14 days of such determination being served on the parties) shall be
final and binding on the parties and their fees shall be borne equally by the parties. 

  

 28 

	11.	Hive Down 

  

	11.1	On the first Business Day immediately following the date of this agreement Opsys and Opsys UK will execute the Hive Down Documentation and complete the Hive Down Reorganisation.

  

	12.	NewCo and NewCo IP Licence 

  

	12.1	Within six months of Completion, Opsys or such Opsys Shareholders or vehicle controlled by such Opsys Shareholders as nominated by Opsys (“Opsys Vehicle”) shall
incorporate a new limited liability company registered in England and Wales (“NewCo”), which shall have the NewCo Articles as its articles of association. 

  

	12.2	As soon as reasonably practicable after the incorporation of NewCo, CDT and Opsys or the Opsys Vehicle shall execute the NewCo Shareholders’ Agreement in the agreed form such
that CDT shall hold 40% of the issued share capital and Opsys or Opsys Vehicle shall hold 60% of the issued share capital of NewCo, and CDT shall procure that Opsys UK grant the NewCo IP Licence to NewCo. 

  

	13.	Opsys IP Licence 

  

	13.1	As soon as practicable after Completion, Opsys UK will grant the Opsys IP Licence to USCO 1 Corporation. 

  

	14.	CDT UK IP Licences and Licence Agreements 

  

	14.1	As soon as practicable after Completion CDT UK and USCO 1 Corporation shall enter into the CDT-USCO IP Licence Agreement and CDT UK and Opsys shall enter into the CDT-NewCo IP
Licence Agreement. 

  

	14.2	On the date hereof Opsys shall grant to CDT UK the Opsys CDT Licence. 

  

	15.	Board Observer 

  

	15.1	Commencing on the date of this agreement, the board of directors of Opsys have the right to nominate an observer to attend all board meetings of CDT provided that such observer is
approved as suitable by CDT, such approval not to be unreasonably withheld or delayed. After the exercise of the Opsys UK Option such right shall continue until Opsys ceases to hold an aggregate Shareholding in CDT of at least 4% of the whole of the
issued share capital of CDT. CDT shall provide the observer with reasonable prior written notice of all meetings (both formal and informal) of the board of directors of CDT and such observer shall be entitled to all information, papers and accounts
presented to such directors in their capacity as directors. The expenses incurred by the observer in attending the meetings shall be for the account of Opsys until the date on which the Opsys UK Option or the Opsys Option is exercised and completed
after which time such expenses are payable by and for the account of CDT. 

  

 29 

	

	15.2	If the Opsys Option is exercised, the shareholders of Opsys on the date of such exercise shall have the right to appoint an observer subject to the terms referred to in
sub-clause 15.1 above where such right shall continue for such time as such shareholders hold an aggregate shareholding in CDT of at least 4% of the whole of the issued share capital of CDT. 

  

	15.3	Where the Chairman of CDT, acting reasonably, considers that the observer has a direct commercial conflict relating to any matter to be discussed at meetings of the board of
directors of CDT, or the information to which he is entitled under sub-clause 15.1, then on request by CDT (to be made one week in advance of such meeting or the date on which the observer would otherwise have been entitled to such information), the
observer (at its discretion) shall either (a) absent itself from such meetings and part of such meetings and or forgo his entitlement to information as the case may be, or (b) appoint an alternative observer to the meeting, or to receive such
information as the case may be, such observer to be approved as suitable by CDT, such approval not to be unreasonably withheld or delayed. 

  

	16.	Warranties and Covenants 

  

	16.1	The Warrantors severally warrant to CDT in the terms of the Warranties in Part 1 of Schedule 3 (Warranties) on the date hereof and on Completion, in terms of the
Warranties in Part 2 of Schedule 3 on the date hereof only and in terms of the Warranties in Part 3 of Schedule 3, on the Hive Down Date. 

  

	16.2	Opsys and Opsys UK shall procure or ensure (as the case may be) that other than in the ordinary and usual course of their businesses, no act shall be performed or omission allowed
in such interval which would result in any of the Warranties being breached or misleading at any time up to and including the time of Completion other than as contemplated by this agreement. 

  

	16.3	The Warrantors accept that CDT is entering into this agreement in reliance upon each of the Warranties. 

  

	16.4	The Warrantors undertake to disclose in writing to CDT anything which is or is likely to constitute a breach of any of the Warranties within two Business Days of it coming to the
notice of any of them both before, at the time of or after Completion. 

  

	16.5	Save in the event of fraud including fraudulent concealment, the Warrantors and Opsys undertake (if any claim is made against any of them in connection with the sale of either the
Opsys UK Option Shares or the Opsys Shares as applicable to CDT) not to make any claim against Opsys UK or its subsidiaries from time to time or any director, employee or adviser of Opsys 

  

 30 

 UK from time to time on whom any of them may have relied before agreeing to any terms of this agreement
or authorising any statement in the Disclosure Letter. 
  

	16.6	Each of the Warranties shall be construed as a separate and independent warranty and (except where expressly provided to the contrary) shall not be limited or restricted by
reference to or inference from the terms of any other Warranty or any other term of this agreement. 

  

	16.7	In the event that any of the Warranties is breached and such breach is incapable of remedy or, if capable of remedy, is not remedied by Opsys by the Completion Date or is untrue or
misleading, Opsys and CDT agree that the sole remedy of CDT in such circumstances will be a reduction in the Option Exercise Price in an amount agreed between the Warrantors and CDT, or in default of such agreement, as determined by order of a court
of competent jurisdiction which is equal to the amount by which the value of the Opsys UK Business is or becomes less than its value would have been if the Warranties had not been breached or would not have been untrue or misleading, subject always
to the proviso that the maximum amount by which the Option Exercise Price will be reduced is $5,000,000. 

  

	16.8	The Option Exercise Price shall be increased by such number of CDT Shares at a value of $16.15 per share as most nearly equals but does not exceed an amount equal to the lesser of:

  

	 	(A)	$1,000,000; and 

  

	 	(B)	the aggregate sum of any monies paid by Dupont to CDT or any member of the CDT Group pursuant to any agreement relating to the licensing of Opsys IP and entered into within twelve
months of the date of this agreement. 

  

	16.9	Opsys undertakes to indemnify CDT against all costs (including legal costs on an indemnity basis as defined in rule 44.4(3) of the Civil Procedure Rules), expenses or other
liabilities which CDT may reasonably incur in connection with the enforcement of any settlement of any claim that any of the Warranties have been breached or the enforcement of any judgment in favour of CDT in respect of such claim under this
agreement. 

  

	16.10	Each of Opsys and CDT agrees to treat any payments in respect of indemnification hereunder or a successful claim for breach of Warranties as an adjustment to the Option Exercise
Price for all purposes (including all Tax purposes). 

  

	16.11	The only Warranties given by the Warrantors in respect of or relating to Intellectual Property are contained in paragraph 25 of Parts 2 and 3 Schedule 3 (Warranties)
and the only Warranties in respect of or relating to 

  

 31 

 Environmental Matters are contained in paragraph 32 of Part 2 of Schedule 3
(Warranties) and no claim or proceedings which could be brought within such paragraphs shall be brought and no liability which arises under such paragraphs shall also arise under any other Warranty. 
  

	16.12	CDT warrants to Opsys in the terms of CDT’s Warranties and CDT’s Warranties shall be deemed to have been repeated immediately before Completion by reference to the facts
and circumstances subsisting at that date on the basis that any reference in such Warranties, whether express or implied, to the date of this agreement is substituted by a reference to the Completion Date. 

  

	16.13	Subject always to sub-clause 16.16, any liability or obligation of any of Opsys or the Warrantors to make a payment to CDT under the terms of this agreement shall first be
determined in the relevant currency and then be translated into U.S. dollars using the prevailing spot rate of exchange as stated in the Financial Times newspaper on the date of such payment. 

  

	16.14	Where a Warranty given by the Warrantors is qualified by the knowledge of the Warrantors, then each Warrantor undertakes in such circumstances that it has made such enquiry into the
subject of the Warranty as is reasonable in the context of a sale of the Company and assets to which it relates including reasonable enquiry of Damoder Reddy and it shall not be a defence that the Warrantors did not appreciate the relevance of any
particular matter. 

  

	16.15	Other than in respect of claims by CDT for breach of warranties given in sub-clause 9.15B (limitation of which shall be governed by sub-clause 17.9), CDT’s sole
remedy in respect to indemnity claims or claims for damages for breach of contract hereunder shall be a corresponding reduction in the Option Exercise Price by such number of CDT Shares as most nearly equals but does not exceed the value of such
claim at a deemed value of $16.15 per share. For the avoidance of doubt CDT shall not be prohibited from seeking the remedy of specific performance for any breach of contract. 

  

	16.16	The Option Exercise Price shall be reduced by such number of CDT Shares at a value of $16.15 per share as most nearly equals but does not exceed an amount equal to three times the
sum of: (i) the amount of money payable to the Universities of Oxford and St Andrews with respect to the provision of research services; (ii) the amount payable to the University of Oxford with respect to leases in Begbroke Business and Science Park
premises (together (i) and (ii) comprise the “University Payables”); (iii) the net current liabilities of Opsys UK at the Hive Down Date. 

  

	16.17	No warranty is given in respect of the recitals and such recitals shall not constitute a representation, warranty or guarantee to the accuracy thereof. 

  

 32 

	16.18	The Warrantors shall not be personally liable (in cash or otherwise) under this agreement or otherwise to CDT, Opsys or Opsys UK for breach of Warranties. 

 

	17.	CDT’s remedies and Opsys’ and CDT’s limitations on liability 

  

	17.1	Subject to sub-clauses 17.2 and 17.4(a) and to the limitations set out in Schedule 4 (Limitations on liability), CDT shall be entitled to claim after Completion that
any of the Warranties has been breached. In accordance with clause 25 (Effect of Completion), Completion shall not in any way constitute a waiver of any of CDT’s rights. 

  

	17.2	CDT shall not be entitled to claim that any fact causes any of the Warranties to be breached if it has been fairly disclosed to CDT in the Disclosure Letter in the absence of any
fraud or fraudulent concealment on the part of any of the Warrantors. 

  

	17.3	CDT shall not be entitled to bring a claim under this agreement nor shall the Option Exercise Price be reduced, if and to the extent that the limitations set out in Schedule
4 (Limitations on liability) apply, in the absence of any fraud or fraudulent concealment on the part of any of the Warrantors. 

  

						
	 17.4
	  	   (a)	 	 	If, between the date of this agreement and Completion, CDT becomes aware (whether it does so by reason of any disclosure made under sub-clause 16.4 (Warranties and covenants) or
otherwise) that there has been any material breach of the Warranties set out in paragraphs 1, 2 and 4 of Part 1 of Schedule 3, and paragraphs 9, 19, 20 and 26 of Part 3 of Schedule 3 (Warranties) except as fairly
disclosed in the Disclosure Letter, CDT may terminate this agreement by notice in writing to Opsys.
			
	 	  	   (b	)	 	If this agreement is terminated in accordance with sub-clause 17.4(a) subject to sub-clause 17.6, all obligations of the parties under this agreement shall end except for those
expressly stated to continue without limit in time but (for the avoidance of doubt) all rights and liabilities of the parties which have accrued before termination shall continue to exist.

  

	17.5	If, following Completion, CDT becomes aware (whether it does so by reason of any disclosure made pursuant to sub-clause 16.4 (Warranties and covenants) or otherwise) that

such number of CDT Shares at a deemed value of $16.15 per share as most nearly equals but does not exceed $5,000,000 or the number of the CDT Shares held by the Warrantors on the date of notification of claim and such claim shall be wholly barred
and unenforceable unless written notice of such claim shall have been served by no later than 5.00 pm on the first anniversary of the Opsys Share Completion Date and any such claim shall be deemed to have been withdrawn (if it has not been
previously satisfied, settled or withdrawn) on the expiry of a period of 18 months from the date of the Opsys Share Completion Date, unless proceedings in respect of it have commenced by being issued and served on the Warrantors.

  

	17.10	Save in the event of fraud or fraudulent concealment by CDT, CDT shall be under no liability under CDT’s Warranties or any indemnities given by CDT in this agreement and any of

	 	(a)	where the liability of CDT in respect of that claim would (but for this paragraph) have been less than £5,000; or 

  

	 	(b)	unless and until the liability in respect of that claim when aggregated with the liability of CDT in respect of all the claims shall exceed £200,000 in which case CDT shall be
liable for the full amount of such claims and not merely the excess. 

  

	18.	Conduct of business before Completion 

  
 Except as part of the Hive Down Reorganisation referred to in sub-clause 11 (Hive Down) or as otherwise expressly provided in this agreement, Opsys
will procure that, between the date of this agreement and Completion, Opsys will carry on business in the ordinary and usual course and not do anything which is not of a routine nature and shall not take any action (including but not limited to, any
action related to personnel, capital expenditure and material contracts) that could reasonably be expected to be material to the business of Opsys UK after Completion without having in each case the consent in writing of CDT, such consent not to be
unreasonably withheld. In particular, the matters listed in Schedule 5 (Conduct of business before Completion) shall require CDT consent. 
  

	19.	Covenants and Undertakings 

  

	19.1	Opsys shall use its reasonable endeavours to procure that all options or rights of the Acquired Employees over or to the issue or allotment of Opsys Shares, under share option

in tort or otherwise, whether arising under UK or European law) suffered or incurred by Opsys relating to an Acquired Employee and arising from:

 35 

	 	(b)	any variation to the terms and conditions of employment of the Acquired Employees (save in respect of any incremental pay increases and pay awards or as a result of any change in
the law) including any failure to receive new share options on equivalent terms to those enjoyed by the Acquired Employees as at the date of this agreement. 

  

	19.4	Opsys undertakes to CDT that on the Completion Date it shall pay the sum of $2,500,000 (the “Account Balance”) to the client account of the Opsys Solicitors in the
name of Opsys (the “Opsys Account”) pending satisfaction of the following conditions, after which the balance of such sum remaining in credit in the Opsys Account may be dealt with by Opsys at Opsys’ sole discretion:

  

	 	(i)	the use of the Account Balance to repay to Dupont the sum of $1.5 million in respect of the cancellation of the Dupont Agreement;

UK by or in respect of any of the Excluded Individuals because of their resignation from office or of their employment being terminated or otherwise and an amount equal to all costs, charges and expenses incurred by Opsys UK which are incidental to
any such claim. For the avoidance of doubt, any liabilities arising because of the resignation from office of any other employee of Opsys UK after Completion shall be for the account of CDT. 

  

	19.6	On the Completion Date, Opsys undertakes to deliver to CDT’s Solicitors undated stock transfer forms relating to the Opsys UK Option Shares in the name of CDT duly executed as
deeds by Opsys and delivered in escrow pending satisfaction of the escrow condition or termination of the escrow referred to in sub-clause 19.7. 

  

	19.7	The escrow condition referred to in sub-clause 19.6 shall be deemed satisfied immediately prior to an Insolvency Event in respect of Opsys, or on completion of the sale and
purchase of the Opsys UK Shares pursuant to the Opsys UK Option whereupon the stock transfer forms shall be released from escrow to CDT, the Option Exercise Price inserted as the consideration therein and the form dated. The escrow shall terminate
and CDT shall or shall instruct its Solicitors to return the stock transfer forms to Opsys on completion of the sale and purchase of the Opsys Shares pursuant to the Opsys Option or in the case of an Insolvency Event of CDT or if a receiver
(including an administrative receiver), liquidator, trustee, administrator, custodian or similar official is appointed in any jurisdiction in respect of the whole or any material part of the business or assets of Opsys UK.

and 

  

 37

in respect of any Excluded Individual. 

  

	20.4	In the event that any of the Redundant Individuals are made redundant (as defined in section 139 of the Employment Rights Act 1996) or otherwise dismissed by Opsys (or any
Associated Company) directly or indirectly as a result of the Hive Down Reorganisation or for an economic, technical or organizational reason, CDT and Opsys UK will jointly and severally indemnify Opsys for any loss, cost, damage or expenses
suffered or incurred by Opsys (or any Associated Company) in terminating their employment, including for the avoidance of doubt, compensation for unfair dismissal paid to such Redundant Individuals (save only in respect of the redundancy costs borne
by Opsys pursuant to sub-clause 19.8 of this Agreement). 

  

	20.5	Opsys UK shall offer consultancy agreements to each of the Acquired Consultants on financial terms which do not differ in any material way from the terms and conditions of
consultancy of each such Acquired Consultant immediately before the Hive down Date. Opsys will indemnify CDT (for itself and as trustee for Opsys UK) for any pensions contributions payable by Opsys UK under such terms and conditions in excess of 5%
of such consultants consultancy fee. In addition, Opsys will indemnify CDT (for itself and as trustee for Opsys UK) against any cost, loss, damage, expense, order or award suffered or incurred by reason of any proceeding claim or demand by any

 38

doubt, any liability incurred by Opsys UK in dismissing any Excluded Individual; and 

  

	 	(d)	arising out of Opsys’s failure to discharge its duty to consult with its Employees in accordance with Regulation 10 of the TUPE Regulations (save insofar as such failure arises
from Opsys UK’s failure to comply with Regulation 10(3) of the TUPE Regulations).

than with Excluded Individuals or the Redundant Individuals. 

  

	21.3	Each undertaking contained in this clause 21 shall be construed as a separate undertaking and to the extent that one or more of the undertakings is held to be against the

	 	(a)	carry on any business other than USCO that competes materially and directly with any business being carried on by Opsys UK on the date of Completion;

than with Excluded Individuals or the Redundant Individuals. 

  

	21.5	The restrictions imposed on Michael Holmes and Alexis Zervoglos by sub-clause 21.4 extend to any actions on his own account and on behalf of any firm, company or other person

	 	(b)	operate as a waiver thereof. 

  

	26.2	The single or partial exercise of any right, power or remedy provided by law or under this agreement shall not preclude any other or further exercise of it or the exercise of any

CDT’s Group provided that in the event of any such assignment the liability of Opsys under this agreement shall be no greater than if such assignment had not taken place.

CDT’s Group including, without prejudice to the generality of the foregoing, any amount of any tax relief obtained by CDT’s Group and any amount by which any taxation for which CDT’s Group is liable is reduced or extinguished, arising
directly or indirectly in consequence of the matter which gives rise to such claim. 

  

	6.	Paragraph 7 shall apply in circumstances where: 

  

	 	(a)	any claim is made against CDT’s Group which is expected to give rise to a claim by CDT against any of the Warrantors under the Warranties; or 

  

	 	(b)	CDT’s Group is expected to make recovery from some other person any sum in respect of any facts or circumstances by reference to which CDT has or is expected to have a claim
against any of the Warrantors under the Warranties; or

	 	(a)	subject to CDT being indemnified and secured to the reasonable satisfaction of CDT by the Warrantors against all costs and expenses incurred which may properly be incurred by reason
of such action, promptly and diligently take all such action as the Warrantors or Opsys may reasonably request (including the institution of proceedings and the instruction of professional advisers approved by the Warrantors or Opsys to act on
behalf of CDT, such approval not to be unreasonably withheld) to avoid, dispute, resist, compromise, defend or appeal against any such claim against CDT’s Group as is referred to in paragraph 6(a) or to make such recovery by CDT’s Group as
is referred to in paragraph 6(b) in accordance with the instructions of the Warrantors to the intent that such action shall be delegated entirely to the Warrantors; and 

  

	 	(b)	subject to CDT being indemnified and secured to the reasonable satisfaction of CDT by the Warrantors against all costs and expenses incurred which may properly and reasonably be
incurred by reason of such action, not settle or compromise any liability or claim to which such action is referable without the prior written consent of the Warrantors which consent shall not be unreasonably withheld or delayed; and

  

	 	(c)	in the case of paragraph 6(c) only, promptly repay to the Warrantors (for the benefit of Opsys or the Opsys Shareholders as applicable) an amount equal to the amount so recovered
or, if lower, the amount by which the Exercise Price was reduced. 

  

	8.	CDT shall promptly: 

  

	 	(a)	inform the Warrantors in writing of any fact, matter, event or circumstance which comes to its notice or to the notice of CDT’s Group whereby it appears that the Warrantors are
or may be liable to make any payment in respect of any claim under the Warranties or whereby it appears CDT’s Group shall become or may become entitled to recover from some other person a sum which is referable to a payment already made by the
Warrantors in respect of such a claim provided that failure to provide such notice shall not release the Warrantors from their obligations hereunder; and 

  

	 	(b)	thereafter keep the Warrantors and Opsys fully informed of all developments in relation thereto provided that failure to provide such notice shall not release the Warrantors from
their obligations hereunder; and 

  

 92

with any proceedings instituted by or against CDT’s Group under paragraphs 6 and 7. 

  

	9.	Nothing in this agreement shall or shall be deemed to relieve CDT of any common law or other duty to mitigate any loss or damage incurred by it. 

  

	10.	In the even of an exercise of the Opsys Option within one year of the Closing Date the references in this Schedule 4 to Opsys shall be deemed to be references to the
shareholders of Opsys at such time. 

  

	11.	No act, action, omission, transaction, claim, election, surrender or disclaimer, or notice or consent of or, recovery, benefit or relief received or obtained by Opsys before
the date on which it forms part of the CDT Group (after the acquisition of the issued share capital of Opsys on exercise of the Opsys Option) shall limit the liability of the Warrantors hereunder. 

  

	12.	Subject to paragraph 8(a) if Opsys remedies a breach of warranty to the reasonable satisfaction of CDT within a period of 30 days from the date on which it became aware of
such breach, CDT shall not bring a claim for such breach hereunder and any such claim made shall be deemed to have been withdrawn.

 Schedule 9 
 (CDT’s Warranties) 
  

	1.1	Authorisations 

  
 CDT has obtained all requisite corporate authorisations and all other applicable governmental, statutory, regulatory or other consents, licences, waivers
or exemptions required to empower it to enter into and to perform its obligations under this agreement and each document to be executed by it at or before Completion. 
  

	1.2	Proper Execution 

  
 This agreement and each document contemplated hereby to be executed at or before Completion, or when the relevant document is executed will constitute
binding obligations on CDT in accordance with their terms. 
  

	1.3	Incorporation and Existence 

  
 CDT is a corporation duly incorporated under the laws of the State of Delaware and has been in continuous existence since incorporation. 
  

	1.4	Share Capital 

  
 As of the date hereof, the authorized capital stock of CDT consists of (i) 21,450,000 shares of Class A Common Stock, of which 15,890,029.75 shares
are issued and outstanding, and (ii) 850,000 shares of Class B Common Stock, par value $.01 per share, of which 311,692 shares are issued and outstanding as of the date hereof. As at Completion, the authorized capital stock of CDT shall
consist of (i) 21,450,000 shares of Class A Common Stock, of which 15,890,029.75 shares will be issued and outstanding, and (ii) 850,000 shares of Class B Common Stock, par value $.01 per share, of which 311,692 shares will be issued
and outstanding. Except for (i) 1,503,950 outstanding options issued pursuant to CDT’s stock incentive plans (including options that CDT is contractually bound to issue pursuant to employment letters, letters of commitment and consultant

of the Company’s Class A Common Stock at $16.15 a share, but these shares have not yet been issued, and the Company has engaged in 
  

 103 

 discussions with an affiliate of Hillman CDT and Hillman CDT 2000 concerning a $10 million investment for
shares of the Company’s Class A Common Stock, but this investment has not yet been funded. In the event that this investment is not funded and assuming that the Company has a need for financing, the Company expects to make alternative
arrangements for the financing with KIA VI and/or KEP VI on terms to be agreed. Except as set forth in Article VIII of the By-Laws and except with respect to 928,793 shares of CDT’s Class A Common Stock that have been issued to certain
strategic investors, there are no preemptive or similar rights on the part of any holders of capital stock of CDT. The CDT Shares issued in satisfaction of the Option Exercise Price hereunder, when issued and delivered in accordance with the terms

	 	(d)	Other than this agreement and except as set out in CDT’s Disclosure Letter, there is no agreement, arrangement or obligation, to which CDT is a party which requires the
creation, allotment, issue, sale, transfer, redemption or repayment of, or the grant to a person of the right (conditional or not) to require the allotment, issue, sale, transfer, redemption or repayment of, a share in the capital of CDT (including
an option or right of pre-emption or conversion).

Price Shares”) solely for such shareholder’s own account and not with a view to, or for sale in connection with, any distribution thereof, including, but not limited to, its limited partners. Each Opsys Shareholder agrees that neither
it nor any of its limited partners if applicable will, directly or indirectly, offer, transfer, sell, pledge, hypothecate or otherwise dispose of any of the Exercise Price Shares (or solicit any offers to buy, purchase or otherwise acquire or take a
pledge of any of the Exercise Price Shares or any interest therein or any rights relating thereto, except in compliance with the Securities Act, all applicable U.S. state securities or “blue sky” laws as they may be amended from time to
time, this Agreement as it may be amended from time to time, the Investor Rights Agreement as it may be amended from time to time, the By-Laws and the Registration Rights Agreement. Each Opsys Shareholder acknowledges that any attempt by any Opsys
Shareholder, directly or indirectly, to offer, transfer, sell, pledge, hypothecate or otherwise dispose of any Exercise Price Shares or any interest therein or any rights relating thereto without complying with the provisions of the Securities Act,
all applicable U.S. state securities or “blue sky” laws as they may be amended from time to time, this Agreement as it may be amended from time to time, the Investor Rights Agreement as it may be amended from time to time, the By-Laws and

(the “By-Law Restrictions”), (ii) understands and consents that as a “Minority Investor” under the By-Laws, the By-Law Restrictions apply to the Exercise Price Shares, (iii) certifies that such Opsys Shareholder has read and
understands the restrictions on the transfer of the Exercise Price Shares set forth in the Registration Rights Agreement, including, but not limited to, the holdback provisions set forth in Section 5 of such agreement (the “Registration Rights
Restrictions”), (iv) understands and consents that as “Registrable Securities” under the Registration Rights Agreement, the Registration Rights Restrictions apply to the Exercise Price Shares, and (v) covenants that such Opsys

or qualified under any U.S. state securities or “blue sky” laws, (ii) it is not anticipated that there will be any public market for the Exercise Price Shares, (iii) the Exercise Price Shares must be held indefinitely and such Opsys

Securities Act and such U.S. state laws or an exemption from registration is available, (iv) Rule 144 promulgated under the Securities Act (“Rule 144”) is not presently available with respect to sales of any securities of CDT and CDT has
made no covenant to make Rule 144 available and Rule 144 is not anticipated to be available in the foreseeable future, (v) when and if the Exercise Price Shares may be disposed of without registration in reliance upon Rule 144, such disposition can
be made only in limited amounts and in accordance with the terms and conditions of such Rule, (vi) if the exemption afforded by Rule 144 is not available, sale of the Exercise Price Shares without registration will require the availability of an
exemption under the Securities Act, (vii) applicable restrictive legends in the forms set forth in Section 6.07 of the By-Laws shall be placed on the certificate representing the Exercise Price Shares and (viii) a notation shall be made in the
appropriate records of CDT indicating that the Exercise Price Shares are subject to restrictions on transfer and, if CDT should in the future engage the services of a stock transfer agent, appropriate stock-transfer instructions will be issued to
such transfer agent with respect to the Exercise Price Shares. 
  

	1.3	Ability to Bear Risk. Each Opsys Shareholder represents and warrants that (i) the financial situation of such Opsys Shareholder is such that it can afford to bear the
economic risk of holding the Exercise Price Shares for an indefinite period and (ii) such Opsys Shareholder can afford to suffer the complete loss of value in the Exercise Price Shares. 

  

	1.4	Access to Information; Sophistication; Lack of Reliance. Each Opsys Shareholder represents and warrants that (i) such Opsys Shareholder has been granted the opportunity to
ask questions of, and receive answers from, representatives of CDT concerning CDT and the terms and conditions of investing in the Exercise Price Shares and to obtain any additional information that such Opsys Shareholder deems necessary, (ii) such
Opsys Shareholder’s knowledge and experience in financial and business matters is such that such Opsys Shareholder is capable of evaluating the merits and risks of investing in the Exercise Price Shares and (iii) such Opsys Shareholder has
carefully reviewed the terms and provisions of the By-Laws and the Registration Rights Agreement and has evaluated the restrictions and obligations contained therein. In furtherance of the foregoing, each Opsys Shareholder represents and warrants
that (i) no representation or warranty, express or implied, whether written or oral, as to the financial condition, results of operations, prospects, properties or business of CDT or as to the desirability or value of holding Exercise Price Shares
has been made to Opsys by or on behalf of CDT, except for those representations and warranties contained in Schedule 11, (ii) such Opsys Shareholder has relied upon its own independent appraisal and investigation, and the advice of such Opsys
Shareholder’s own counsel, tax advisors and other advisors, regarding the risks of holding 

  

 111 

 Exercise Price Shares and (iii) such Opsys Shareholder will continue to bear sole responsibility for
making its own independent evaluation and monitoring of the risks of holding Exercise Price Shares. 
  

	1.5	Accredited Investors/Non-U.S. Persons. Each Opsys Shareholder represents and warrants that it and its limited partners (if any) are either “accredited investors” as
such term is defined in Rule 501(a) promulgated under the Securities Act or that it and its limited partners are not “U.S. persons” and are not acquiring the Exercise Price Shares for the account or benefit of any “U.S. persons”
as such term is defined in Regulation S promulgated under the Securities Act.
