Dear SB,

Further to our recent discussions, I am pleased to confirm your secondment to CDT in Japan on an expatriate assignment.

This letter defines the terms and conditions applying to your assignment in Tokyo, Japan asVP,Commercial. During this assignment you will continue to report to the Chief Executive Officer of CDT.

It is currently expected that your assignment will be approximately 14 months (beginning approximately 6 February 2006 and ending approximately 31 March 2007) ("Employment Term"). The Employment Term may be extended and you will receive notice of any such extension. You agree that you will continue to remain employed at CDT through the Employment Term or any extension of the Employment Term. You also agree that if you intend to resign at the end of the Employment Term or any extension of the Employment Term, as the case may be, you will give the Company at least six months' prior written notice. Likewise, if the Company intends to terminate your employment at the end of the Employment Term, or any extension of the Employment Term other than a termination for cause, it will give you at least six months' prior written notice. At the end of the Employment Term or any extension thereof, we will pay reasonable costs of repatriating you to the United States.

Your compensation and benefits package outlined in this memo is designed to provide you with a level of income and benefits that are comparable to those that you would receive in the United States. We have taken into consideration the additional costs that you can reasonably anticipate as a result of living in Tokyo, Japan.

At the time that your foreign assignment ends, you will stop receiving any premiums, allowances and/or differentials provided under CDT's Temporary Foreign Assignment. The terms and conditions outlined in this letter will be in effect only for the period of this assignment.

This offer and your start date are contingent upon approval of the appropriate visa within a reasonable period of time, as determined by CDT at its sole discretion.

1. Total Compensation

To establish your total compensation, the intent of our approach is that on an overall basis, after all allowances and reimbursements, changes to your standard of living are minimised.

2. Base Salary and Benefit Programs

Your base salary will remain unchanged at $280,000 per annum. Your salary will be administered according to US salary and payroll guidelines. Your next salary review date will be 1 January 2007.

You and your eligible family will continue to be covered under appropriate benefit plans providing you continue to meet all requirements of eligibility. Cover for you and your family will be extended to ensure that private medical and dental coverage is provided in Japan.

You will continue to participate in the US benefit plans, subject to the rules of such plans. You may elect to participate in the 401K Plan and contribute a maximum of 5% of your base salary, subject to the rules of the plan. Upon completion of your assignment the Company will contribute a backdated lump sum equivalent to 5% of your base salary over the duration of the assignment, subject to the rules of the plan.

You will be eligible to take vacation in line with the vacation policy of CDT Inc. However, during the course of the overseas assignment you will be eligible for Japanese public holidays rather than US public holidays.

3. Currency fluctuations

The Company hereby agrees, for the duration of your assignment, to protect you from any excessive adverse currency fluctuations when converting salary and other US paid remuneration from US dollars (USD) to Japanese Yen (JPY).  For this purpose the rate of exchange accepted as the benchmark for protection is USD1/JPY114. If the exchange rate decreases by more than 5% the Company will reimburse any difference over and above 5%.  Reimbursement will be via the normal company expense procedure. Supporting documents will be required showing the amounts converted with proof of the exchange rate used by the banking institution.

4. Special Bonus Plan

Subject to approval by the Compensation Committee, and subject to the Rules of the Plan, the final tranche of shares that you currently hold under the Special Bonus Plan will vest immediately upon successful completion of your overseas assignment (the Employment Term), (as opposed to the final vesting date of 22 December 2007).

If you do not complete the full assignment in Japan, then all shares due to you under the Special Bonus Plan will vest in accordance with the schedule outlined in our letter to you of 16 December 2004.

5. Tax Policy relating to assignments

The company will reimburse usual and customary charges up to $7,500 per full yearfor the cost of preparing all necessary income tax returns at the end of each tax year in which there is foreign service compensation.

Please contact Sarah Read in Finance to discuss any questions you may have with respect to taxation issues.

6. Cost of Living Differential

Normally, a cost of living differential is paid to cover the differences between the home country and host country in the cost of goods and services. This differential is based on the typical buying patterns and is derived from standardized tables for persons at the same salary level and family size.

This differential is subject to increase or decrease at the discretion of the company depending on changes in the factors from which it is derived. This differential will be reviewed formally on an annual basis. The amount of this allowance for a staff member going to Japan from the US is $2,890 per month for the duration of the assignment.
