Re: DuPont/Nanosys Collaboration Agreement
Dear Xxx:
The following represents our understanding of the status of our agreement with

Pursuant to section 10.2, of the Agreement, the Agreement is scheduled to
terminate three months after the Commencement Date of the Agreement, which, as
amended in Amendment A to the Agreement, is May 17th, 2004, unless the Parties
have agreed in writing to continue the collaboration under the Agreement.
At present, both Parties hereby agree to continue the Collaboration under the
Agreement. As a next step, the Parties will work expeditiously together to
formulate mutually acceptable Statements of Work, based on the learnings to
date. These Statements of Work will provide the sole basis for determining the
appropriate timing and level of ongoing funding for future tasks.
Please indicate XxXxxx'x agreement by signing and returning this letter to my
