Exhibit 10.15

September 4, 2003

William Britts

11431 Willows RD NE

Redmond, WA 98052

Dear Bill:

Thank you for your patience while we cleared up certain matters with regard to your relocation to Paris. This letter is to confirm arrangements with you as Executive Vice President of Sales & Marketing as detailed in this letter. You continue to report to Peter van Oppen, Chairman of the Board and CEO. The original effective date will be July 1, 2002. While nothing in this letter or in your relocation to Paris, France alters your status as an at-will employee of ADIC, you acknowledge that this assignment is currently expected to continue through fiscal year 2004. Any change will be by mutual agreement or as determined by governmental laws, rules or regulations. All references to currency in this letter are in US dollars unless otherwise noted.

COMPENSATION:

Your base rate of pay will be $100,000 annually, subject to federal income tax and other normal withholding. Additionally, you will receive $157,500 gross in a Travel Hardship Allowance that will be subject to French social taxes but not French income taxes. Your base salary will be further supplemented by the payment of a housing allowance, U.S. Hypothetical Housing Deduction and cost of living differential. These allowances are described in more detail in following sections.

TAXES:

Tax equalization is designed to assure that you do not incur additional tax liability as a result of the assignment in excess of the tax liability you would have incurred had you remained in the United States. During the course of your assignment, a hypothetical tax will be computed and withheld from your salary which is an approximation of your annual tax liability on your base income had you remained in the U.S.

If you receive any bonuses, or incentives in addition to salary, they are also subject to hypothetical tax. The final hypothetical tax will be calculated as your tax return is finalized each year, which determines your final actual income tax obligation for the year.

ADIC will be responsible for U.S. and/or foreign taxes greater than the final hypothetical tax, which were incurred as a result of your expatriate assignment. The settlement of taxes is subject to final review of any taxes paid on behalf of an expatriate or advances provided to an expatriate or advances provided to an expatriate as part of a tax settlement. However, because the Company is undertaking the obligation to pay your taxes in excess of your U.S. obligation, the amount of any refund of taxes received by you from the U.S. Internal Revenue Service must paid to ADIC. We will make available to you, for both foreign and domestic taxes, consultation, and preparation services provided by a source that ADIC chooses. This work will be done by Chris Rieke who is an International Tax Accountant with Miller, Rieke, Whitsell and Co.

HOME LEAVE:

ADIC will provide you and each member of your family with two (2) round trip airfares per year. These airfares may be used by you to return home or to bring family members to Europe.

VISA:

Because your VISA may not be ready as needed, ADIC will pay for a round trip visit to San Francisco, CA for you to obtain the required VISAs.

REPATRIATION:
