Explanation of Responses:

* If the form is filed by more than one reporting person, see Instruction 4(b)(v).
** Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1) Held through "contrats de capitalization," a form of life insurance program for the benefit of the reporting person's three minor children, where the reporting person maintains investment control over the Microsoft shares held in the program. The reporting person disclaims beneficial ownership of these securities, and this report shall not be deemed an admission that the reporting person is the beneficial owner of the securiteis for purposes of Section 16 or any other purpose.
(2) The reporting person is the Settlor of the Trust and not a Trustee or beneficiary of the Trust. The reporting person therefore disclaims beneficial ownership of all securities held by the Trust, and this report should not be deemed an admission that the reporting person is the beneficial owner of such securities for purposes of Section 16 or for any other purpose.
(3) On November 10, 2004, the Trust entered into an equity swap agreement with a securities broker covering 722,912 Microsoft shares (the "Shares") under which, on the expiration date of the agreement (May 16, 2005), one of the following will occur: (i) if the market price of Microsoft stock on the expiration date is above $29.72, the broker will pay the Trust an amount equal to the difference between the market price and $29.72 multiplied by the number of Shares; (ii) if the market price of Microsoft stock on the expiration date is below $29.72, the Trust will pay the broker an amount equal to the difference between $29.72 and the market price multiplied by the number of Shares; or (iii) if the market price on the expiration date equals $29.72, no payment will be made by either party. An amount equal to any dividends payable on the Shares during the term of the agreement will be paid in cash by the broker to the Trust, less applicable withholding taxes.
(4) During the term of the agreement, the Trust will pay the broker a fee equal to the 3-month USD LIBOR rate plus 10 basis points multiplied by the value of the Shares.
