Exhibit A.11

November 27, 2002

All Employees:

        On November 1, 2002, we commenced an offer to exchange certain existing stock options for new options and provided each of you with an Offer to Exchange and Option Exchange Election Form (the "offering documents") describing the terms and conditions of the offer.

        The Securities and Exchange Commission (the "SEC") has reviewed and commented on the Company's offering documents and we have amended them to reflect the SEC's comments. The revised offering documents are being provided to you with this memo. Summarized below are some of the changes that we have made to the offering documents. You are encouraged, however, to review the revised offering documents in their entirety.

        Generally all other terms of the offer, including the price and the calculation of the number of options to be granted in exchange for options tendered in the exchange offer, remain unchanged from the offering documents provided to you on November 1, 2002, and subsequently discussed in the question and answer sessions during the week of November 4, 2002. The offer will still expire at 5:00 p.m. on December 9, 2002, unless we extend the offer period.

        The following documents are attached for your information and use.

        Several employees have asked questions regarding the terms and mechanics of the offer. Reprinted below are the questions and our answers.

        If you have any other questions regarding the offering, please contact me at (425) 415-6847.
