The First Sale Stock Consideration

3.1 The First Sale Stock Consideration is the payment by the Purchaser to the Vendor of USD $ 13,880,000 in cleared cash funds by telegraphic transfer to an account nominated by the Vendor for the purpose subject to and in accordance with the terms of this Agreement comprised of the following elements:

(a) a basic amount of US $12,050,000; and

(c) 100% of the loans advanced by the Vendor to the Corporation from 1 June 2003 to 11 August 2003 in respect of the Corporation’s Cash Flow needs (such 100% share amounting to US $ l,300,000).

The amounts set out in (b) and (c) above in respect of the Cash Flow requirements of the Corporation are shown on the bank statements in Part 4 of Schedule 2.

The Negative Net Worth Elimination Condition

3.2 The Vendor and the Purchaser hereby agree and acknowledge that it is a condition of the purchase of the First Sale Stock that prior to the First Closing, all negative Net Worth of the Corporation is completely eliminated. The Vendor hereby undertakes that by capitalisation of all of its outstanding loan balance due from the Corporation as of 11 August 2003, the Vendor shall completely eliminate all negative Net Worth of the Corporation prior to the First Closing. To achieve this prior to the First Closing, the Vendor shall capitalize all of its outstanding loan balance due from the Corporation as of 11 August 2003. This shall be referred to in this Agreement as the (“Negative Net Worth Elimination Condition”). Such capitalization shall take place without the issuance of any stock to the Vendor.

3.3 In order to verify that the negative Net Worth was completely eliminated, the parties hereby further acknowledge and accept that:

(a) the Corporation shall as soon as possible and in any event, within one (1) month following the First Closing prepare and submit to the Purchaser its balance sheet at the time of the First Closing and shall certify that the negative Net Worth was completely eliminated prior to the First Closing. The balance sheet and the certification submitted shall utilize and shall be strictly subject to the definition of negative Net Worth in Schedule 1;

4

(b) the Purchaser shall as soon as possible and in any event, within one (1) month after receipt of all of the documents described above in Clause 3.3(a), investigate whether the negative Net Worth was completely eliminated;

(c) within fifteen (15) days after the Vendor’s receipt of notification regarding the outcome of the investigation referred to in Clause 3.3(b), the Vendor and the Purchaser shall confer to reach a mutual agreement regarding the elimination of all negative Net Worth. If Vendor and Purchaser do not reach a mutual agreement regarding the Negative Net Worth Elimination Condition, the Vendor and the Purchaser shall appoint a neutral accounting firm, of which both parties approve, and such independent accounting firm shall issue an opinion regarding any outstanding or unresolved issued between the parties related to the Negative Net Worth Elimination Condition. The opinion of such neutral accountants shall be final and binding and, accordingly, the Vendor and the Purchaser shall have no further claim under this Agreement in respect of the Negative Net Worth Elimination Condition once such opinion has been issued;

(d) in the event that, through the above described process, it is confirmed that the negative Net Worth was not completely eliminated at the time of the First Closing, then the Purchaser shall be entitled to receive the amount corresponding to the actual negative Net Worth which exists at the time of the First Closing from the First Additional Escrow Amount in the Escrow Account subject to Clauses 4.5 and 4.6;

(e) in the event that negative Net Worth as of the First Closing is more than the First Additional Escrow Amount in the Escrow Account, the Vendor shall reimburse such excess to the Purchaser.

4. Escrow Account

4.1 At First Closing:

(a) Ten percent of the First Sale Stock Consideration (the “First Sale Escrow Amount”) shall be held back from the First Sale Stock Consideration and this shall be placed in an escrow account mutually acceptable to the parties (the “Escrow Account”); and

(b) In addition to the amount set forth in Clause 4.1(a), ten percent of the First Sale Stock Consideration (the “First Additional Escrow Amount”) shall be held back from the First Sale Stock Consideration and this shall be placed in the Escrow Account.

5

4.2 At Second Closing:

(a) An amount equal to 10% of the Second Sale Stock Consideration (the “Second Sale Escrow Amount”) shall be held back from the Second Sale Stock Consideration and this shall be placed in the Escrow Account; and

(b) 50% of the maximum amount of the expense for the Exit Bonus Plan which is projected and agreed by the parties at the Second Closing (the “Second Additional Escrow Amount”) shall be placed in the Escrow Account. The parties shall use their best efforts to determine the maximum amount of the expense for the Exit Bonus Plan prior to the Second Closing, and in the event the parties cannot agree, PricewaterhouseCoopers shall make the final and binding determination of such amount.

4.3 This Clause 4 and the Escrow Instructions shall apply to the Escrow Account. Each of the Vendor and the Purchaser hereby undertakes to give instructions in respect of the Escrow Account promptly and efficiently, and in good faith, to give effect to the spirit and intent of this Agreement.

4.4 Any costs and fees associated with establishing and operating the Escrow Account shall be borne by the Vendor and the Purchaser each bearing 50% and the Vendor and the Purchaser shall indemnify Osborne Clarke and City-Yuwa accordingly. Any interest accruing on the amount held in the Escrow Account shall (unless otherwise expressly stated in this Agreement) belong to the party to which such funds are ultimately released. The parties hereto agree that no Escrow Agent (as defined in Schedule 9) shall be liable for any damages whatsoever to any party.

The First Additional Escrow Amount

4.5 The purpose of holding the First Additional Escrow Amount in the Escrow Account shall only be to provide the Purchaser with security as regards the Negative Net Worth Elimination Condition.

4.6 The Purchaser shall procure that the First Additional Escrow Amount is released to the Vendor within fifteen (15) days after the date on which the Vendor and the Purchaser agree on all aspects of the Negative Net Worth Elimination Condition or the neutral accountants referred to in Clause 3.3(c) have issued their decision regarding any issues not agreed upon by the parties. Provided that when the Purchaser has the right to receive an amount equal to the amount of negative Net Worth pursuant to Clause 3.3(d), such amount shall be deducted and only the remainder shall be released to the Vendor. If the Net Worth of the Corporation as

6

of the First Closing is positive, the Purchaser shall promptly reimburse to the Vendor such positive amount.

The First Sale Escrow Amount

4.7 The purpose of holding the First Sale Escrow Amount in the Escrow Account shall only be to provide security to the Purchaser in respect of the breach of the Vendor Warranties and the CDT UK Warranties.

4.8 Except as provided below, the Purchaser shall procure that the First Sale Escrow Amount is released to the Vendor on Second Closing or if earlier the third anniversary of the date of this Agreement.

4.9 In the event that the Purchaser has a claim in respect of the Vendor Warranties or the CDT UK Warranties which is Finally Resolved by Second Closing then the Purchaser shall be entitled to deduct the Finally Resolved amount of its claim from the First Sale Escrow Amount upon such claim becoming Finally Resolved but always after taking into account the Limitations on Liability of the Vendor and CDT UK at Schedule 7.

4.10 If the Purchaser makes a Claim against the Vendor or CDT UK and such amount as Finally Resolved exceeds the First Sale Escrow Amount, the Purchaser shall deduct such excess from the Second Sale Consideration or, in the event that it is entitled and so decides not to complete the Second Closing due to a Material Occurrence, may bring a claim directly against any property of the Vendor and/or CDT UK.

4.11 In the event that the Purchaser has a claim in respect of the Vendor Warranties or the CDT UK Warranties which is NOT Finally Resolved before the due date for release of the First Sale Escrow Amount then the following provisions shall apply (and the Purchaser shall take all such steps as are reasonably necessary to procure compliance with the same).

(a) The Purchaser, no later than 20 days following the due date for release of the First Sale Escrow Amount, shall apply to the Expert, requesting a determination as to what amount might reasonably represent the value of the damages in respect of the outstanding claim after taking into account the Limitations on liability of the Vendor and CDT UK in Schedule 7 (the “Interim Claim Amount”). For the avoidance of doubt the Interim Claim Amount shall have no effect on the amount determined upon such claim becoming Finally Resolved. All costs and fees of the Expert shall be borne as the Expert directs.

7

(b) Following the Expert’s determination as to the Interim Claim Amount, if and to the extent that the Interim Claim Amount is less than the amount then held in the Escrow Account in respect of the First Sale Escrow Amount then the difference between the amount held in the Escrow Account in respect of the First Sale Escrow Amount and the Interim Claim Amount shall be released to the Vendor.

(c) Following the Expert’s determination as to the Interim Claim Amount, if and to the extent that the Interim Claim Amount exceeds the amount then held in the Escrow Account in respect of the First Sale Escrow Amount then no monies shall be released from the Escrow Account in respect of the First Sale Escrow Amount until the claim is Finally Resolved.

(d) In the event that the Purchaser does not obtain the Expert’s determination specifying the Interim Claim Amount within 90 days after the due date for release of the First Sale Escrow Amount then all amounts standing to the credit of the Escrow Account in respect of the First Sale Escrow Amount shall be released to the Vendor. Provided that if the failure to obtain the Expert’s determination is caused by the failure of the Vendor or any CDT Affiliate to cooperate with the Expert, such time limit stated herein shall not apply.

(e) If the Expert fails to make a determination through no fault or delay of either party, the Escrow Accounts shall be maintained without change and the parties shall use their best efforts to resolve outstanding issues.

The Second Sale Escrow Amount

4.12 The purpose of holding the Second Sale Escrow Amount in the Escrow Account shall only be to provide security to the Purchaser in respect of the breach of the Vendor Warranties or the CDT UK Warranties.

4.13 Except as provided below, the Purchaser shall procure that the Second Sale Escrow Amount is released to the Vendor on the date falling 12 months after Second Closing.

4.14 In the event that the Purchaser has a claim in respect of the breach of the Vendor Warranties or the CDT UK Warranties which is Finally Resolved before the due date for release of the Second Sale Escrow Amount then the Purchaser shall be entitled to deduct the Finally Resolved amount of its claim from the Second Sale Escrow Amount upon such claim becoming Finally Resolved after taking into account the Limitations on Liability of the Vendor and CDT UK at Schedule 7 and any amounts deducted in respect of such claim from the First Sale Escrow Amount.

8

4.15 In the event that the Purchaser has a claim in respect of the Vendor Warranties or the CDT UK Warranties which is NOT Finally Resolved by the due date for release of the Second Sale Escrow Amount then the following provisions shall apply (and the Purchaser shall take all such steps as are necessary to procure compliance with the same).

(a) The Purchaser, no later than 20 days following the due date for release of the Second Sale Escrow Amount, shall apply to the Expert, requesting a determination as to what amount might reasonably represent the value of the damages in respect of the outstanding claim after taking into account the Limitations on liability of the Vendor and CDT UK in Schedule 7 (the “Interim Claim Amount”). All costs and fees of the Expert shall be borne as the Expert directs.

(b) Following the Expert’s determination as to the Interim Claim Amount, if and to the extent that the Interim Claim Amount is less than the amount then held in the Escrow Account then the difference between the amount held in the Escrow Account and the Interim Claim Amount shall be released to the Vendor.

(c) Following the Expert’s determination as to the Interim Claim Amount, if and to the extent that the Interim Claim Amount exceeds the amount then held in the Escrow Account in respect of the Second Sale Escrow Amount then no monies shall be released from the Escrow Account until the claim is Finally Resolved and the Purchaser may withhold any such excess amount from the Second Sale Consideration until such time as the Claim is Finally Resolved.

(d) In the event that the Purchaser does not obtain the Expert’s determination specifying the Interim Claim Amount within 90 days after the due date for release of the Second Sale Escrow Amount then all amounts standing to the credit of the Escrow Account shall be released to the Vendor. Provided that if the failure to obtain the Expert’s determination is caused by delay by the Expert or the failure of the Vendor or any CDT Affiliate to cooperate with the Expert, such time limit stated herein shall not apply.

(e) If the Expert fails to make a determination through no fault or delay of either party, the Escrow Accounts shall be maintained without change and the parties shall use their best efforts to resolve outstanding issues.

The Second Additional Escrow Amount

4.16 The purpose of holding the Second Additional Escrow Amount in the Escrow Account shall only be to cover the funding responsibility of the Vendor for the Exit Bonus Plan (defined in the JVA) for the JV Period (defined in the JVA).

4.17 Pursuant to the Exit Bonus Plan which shall be adopted as of execution of the JVA, the Vendor shall be responsible to the Purchaser for 50% of the payment to the employees of the Corporation under the Exit Bonus Plan, in which actual payment will be made after 6 months from the Second Closing. The Purchaser shall be entitled to receive from the Second Additional Escrow Amount an amount equal to 50% of the actual payment to the employees of the Corporation under the Exit Bonus Plan and the Purchaser shall take all necessary steps to ensure that the remainder, if any, of the Second Additional Escrow Amount is released to the Vendor within fifteen (15) days after the date on which the payment for the Exit Bonus Plan was made by the Corporation.

4.18 In the event that the Purchaser will not proceed with purchase of the Second Sale Stock due to a Material Occurrence, the Vendor shall be responsible for 50% of the payments (if any) made in relation to this Exit Bonus Plan to the Purchaser. In this case, the Purchaser shall be entitled to receive such amount from the First Sales Escrow Amount and in the execution of the Pledged Securities pursuant to Clause 5.

4.19 The parties hereto acknowledge and agree that the release to the Vendor of any escrow amount shall not release any claims against the Vendor or CDT UK.

4.20 Any reference to the appointment or reference to “the Expert” in this Clause 4 shall be dealt with as contemplated by Clause 18.14 below.

5. Pledge Agreement

5.1 At First Closing, the Vendor shall deliver to the Purchaser the Pledge Agreement (duly executed by the Vendor) together with the Pledged Securities.

5.2 The purpose of the Pledge Agreement shall only be to provide security to the Purchaser in respect of any breach of this Agreement, the JVA and the Ancillary Agreements by the Vendor or CDT UK.

5.3 Under the terms of Clause 9 of the Pledge Agreement, the Purchaser shall be entitled to satisfy itself as to the payment of a Qualifying Proven Claim. The following provisions of this Clause 5 set out and specify in detail the circumstances in which Clause 9 of the Pledge Agreement may be invoked.

10

5.4 In order for a claim by the Purchaser to be a (“Qualifying Proven Claim”) then:

(a) such claim must be for a Qualifying Excess; and

(b) such claim must be Finally Resolved; and

(c) a Material Occurrence must have occurred; and

(d) the Purchaser must have made an irrevocable election in writing not to proceed with the purchase of the Second Sale Stock within 60 days of the date of the occurrence of the Material Occurrence or (if later) within 60 days of the Purchaser becoming aware of the occurrence of the Material Occurrence.

5.5 Transfer of the Pledged Securities shall be executed in compliance with related US law.

5.6 On the occasion of any demand by the Purchaser for payment in respect of a Qualifying Proven Claim and these remain unpaid by the Vendor or CDT UK within 90 days of such demand, the valuation of the Common Stock and determination of the number of Pledged Securities to be transferred into the Purchaser’s name as contemplated by Clause 9 of the Pledge Agreement shall be settled in accordance with the following provisions:

(a) first by the Vendor and the Purchaser attempting to agree the valuation of the Common Stock based on the Fair Market Value of the Corporation and the resultant Fair Stock Price, but failing such agreement within 30 days of the commencement of such discussions,

(b) by the Valuation Expert determining the valuation of the Common Stock based on the Fair Market Value of the Corporation and the resultant Fair Stock Price (the “Expert Determination Method”).

5.7 The “Fair Market Value” of the Corporation shall be the fair market value of the entire issued Common Stock of the Corporation taking into account the following assumptions:

(a) the transfer is between a willing seller and a willing purchaser;

(b) the valuation point is the date on which the Valuation Expert makes his determination (the “Determination Date”);

(c) all information regarding the Corporation is fully disclosed;

11

(d) any loan capital provided by the Purchaser up to its USD $6.83 million commitment pursuant to Clause 12 of the JVA shall be deemed equity capital for these purposes; and

(e) the maximum Fair Market Value that the Valuation Expert may determine shall be the Second Sale Stock Consideration calculated on the same basis as if at the Second Closing but with the adjustment to be made in accordance with Clause 10 as at the Determination Date.

5.8 The “Fair Stock Price” shall be such Fair Market Value divided by the number of shares of Common Stock in issue on the Determination Date (assuming that there are only shares of Common Stock in issue). In the event that there are other shares in issue apart from Common Stock then the Fair Stock Price shall be determined by agreement between the parties or by such other method as the Valuation Expert considers to be appropriate in each case considering the capital structure of the Corporation.

5.9 The Corporation hereby undertakes to make available to the Stockholders and the Valuation Expert such information as they each may reasonably require for the purpose of determining the Fair Market Value and the Fair Stock Price.

5.10 Should the determination of the Fair Market Value and the Fair Stock Price fall to be determined by the Expert Determination Method then the following provisions shall apply.

5.11 An independent internationally recognised accounting firm or investment bank with no direct or indirect significant business relationship with either Stockholder or members of their respective Groups (the “Valuation Expert”) shall be appointed to determine the Fair Market Value and the Fair Stock Price having regard to the principles set out in this Agreement by agreement between the Stockholders or failing such agreement after 10 Business Days of the commencement of such discussions, by the head of the San Francisco Office of American Arbitration Association or their designee.

5.12 The Valuation Expert shall act as an expert and not as an arbitrator. The Stockholders shall each have the right to make written representations to the Valuation Expert and shall each ensure that all relevant circumstances concerning the valuation are fully disclosed to the Valuation Expert. The decision of the Valuation Expert shall, in the absence of manifest error, be final and binding on the Stockholders and CDT UK. All costs incurred by the Valuation Expert shall be borne by the Vendor and the Purchaser in equal shares unless the Valuation Expert determines otherwise.

12

5.13 Unless otherwise agreed, the Pledge Agreement shall terminate on the Second Closing or the third anniversary of the First Closing which ever occurs first. Provided that if the third anniversary of the First Closing occurs prior to the Second Closing, the Purchaser shall return to the Vendor the certificates in respect of the Pledged Securities not transferred pursuant to this Clause 5 and the Pledge Agreement.

5.14 If the value of the Pledged Securities as determined by the Valuation Expert is inadequate to fully compensate the Purchaser for the amount of the Qualifying Proven Claim, including any costs incurred with enforcing the Pledge Agreement, the Purchaser may bring a claim directly against the Vendor and/or CDT UK.

6. Vendor’s Put Option

6.1 Subject to the terms of this Agreement and of the Joint Venture Agreement, at any time after two years have elapsed from the date hereof, the Vendor may send notice to the Purchaser that the Vendor is exercising its put option to sell all, but not some, of its shares of Common Stock in the Corporation. Within three months after receipt of such notice, the Purchaser shall be required to purchase all of the outstanding shares of Common Stock of the Corporation held by the Vendor. The price for such purchase of the Second Sale Stock shall be the Second Sale Stock Consideration as set forth in Clause 10.

6.2 Such sale shall take place at a place agreed upon by the Vendor and the Purchaser. Such sale shall be subject to the Title Warranties only and the parties shall deliver the documents and things required to be delivered pursuant to Clause 14.

(f) at least 5 of the 10 Key Employees of which at least 3 are among the top 5 of the Key Employees set forth in Annexure 1 to this Agreement provided the Purchaser has not directly or indirectly taken any action which is calculated to persuade any of these to terminate their association with the Corporation, give notice of the termination of their employment with the Corporation in such circumstances that:

(i) the dates of expiry of all the notices of termination occur within a period of 3 months of each other;

(ii) the end of such 3 month period referred to in (i) above occurs not more than 6 months prior to the second anniversary of First Closing.

7.2 Within three (3) months after receipt of such notice by the Vendor, the Purchaser shall be required to purchase all of the outstanding shares of Common Stock of the Corporation held by the Vendor. The price for such purchase of the Second Sale Stock shall be the Second Sale Stock Consideration as set forth in Clause 10.

14

7.3 Such sale shall take place at a place agreed upon by the Vendor and the Purchaser. Such sale shall be subject to the Title Warranties and the parties shall deliver the documents and things required to be delivered pursuant to Clause 14.

8. Vendor’s Call Option

8.1 If:

(a) the Purchaser suffers an insolvency event (meaning a formal insolvency procedure such as bankruptcy, administration, receivership, liquidation or anything analogous to the same in the relevant jurisdiction other than as part of a solvent and bona fide reconstruction or amalgamation); or

(b) pursuant to sub-clause 6.4, a Material Occurrence has occurred and either

8.2 Within three (3) months after receipt of such notice by the Vendor, the Purchaser shall be required to sell all of the First Sale Stock and the Preferred Stock to the Vendor on terms that the Title Warranties shall be deemed to be given by the Purchaser to the Vendor in connection with the purchase of the First Sale Stock and Preferred Stock by the Vendor.

Such a proposal shall be treated by the Vendor in accordance with the JVA.

9.4 The Second Sale Stock Consideration shall for the purpose of this Clause 9 be calculated on the same basis as if at the Second Closing, but with the adjustment to be made in accordance with Clause 10 being the date on which the Vendor or the Purchaser (as the case may require) offers to sell its Second Sale Stock pursuant to this clause.

10. Second Sale Stock Consideration

17

Corporation Covenant) which is Finally Resolved at Second Closing and in respect of which it has not been satisfied, then the Purchaser shall be entitled to deduct the Finally Resolved amount of such claim from the Second Sale Stock Consideration.

(a) The Purchaser, no later than 20 days following the due date for the payment of the Second Sale Consideration, shall apply to the Expert, requesting a determination as to what amount might reasonably represent the value of the damages in respect of the outstanding claim after taking into account the Limitations on liability of the Vendor and CDT UK in Schedule 7 and the Corporation in Schedule 8 (the “Second Interim Claim Amount”).

18

CDT UK or the Corporation and recovered damages from the Vendor, CDT UK or the Corporation (as appropriate) then the amount of any deduction from the Second Sale Stock Consideration shall be adjusted, if appropriate, to take account of such recovery so that the Purchaser does not receive the windfall benefit of a double recovery. To the extent that the Purchaser is compensated for its loss in respect of a particular matter or thing by way of adjustment to the Second Sale Stock Consideration as contemplated by this Agreement then the Purchaser shall not thereafter be entitled to recover damages in respect of a breach of this Agreement or the Ancillary Agreements by the Vendor, CDT UK or the Corporation.
