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

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-

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.

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.

If:

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)

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.

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.

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:

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

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

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 ▇▇▇▇▇▇▇▇ Chance or another mutually acceptable independent international law firm (the “Expert”) reasonably agreed between CDT and Opsys to:

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;

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

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:

(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

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.

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.

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:

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;

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

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:

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

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.

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.

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.

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

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

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 ▇▇▇▇▇▇▇ ▇▇▇▇▇ 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 ▇▇▇▇▇▇▇ 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.

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.

17.4	(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.

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 such claims shall be wholly barred and unenforceable unless and to the extent that written notice of such claims (specifying in reasonable detail the circumstances which give rise to the claim, the breach that results and the amount claimed) has been given to CDT before the expiration of a period ending three months after the issuance of the audited accounts of CDT for the current accounting period of CDT ending after Completion. CDT at its sole discretion shall have the right to satisfy any claims under this agreement, including but not limited to indemnification, loss, breach, costs, expenses payable by it to Opsys by cash payment or by increasing the Option Exercise Price by such whole number of shares in CDT as most nearly equal but do not exceed the value of such claims and for such purposes the CDT Shares shall be deemed to have a value of $16.15 (or such other value as is appropriate after operation of clause 10 (Dilution and Reorganisation).

(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.
