Chapter 23B.08.510 and .570 of the Washington Business Corporation Act authorizes a corporation to indemnify its directors, officers, employees, or agents in terms sufficiently broad to permit such indemnification under certain circumstances for liabilities (including provisions permitting advances for expenses incurred) arising under the 1933 Act. In addition, Microsoft maintains directors' and officers' liability insurance under which Microsoft's directors and officers are insured against loss (as defined in the policy) as a result of claims brought against them for their wrongful acts in such capacities. Item 7. Exemption from Registration Claimed. Not Applicable. 3 Item 8. Exhibits. The Exhibits to this registration statement are listed in the Index to Exhibits on page 7. Item 9. Undertakings. (a) The undersigned registrant hereby undertakes: (1) To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement: To include any material information with respect to the plan of distribution not previously disclosed in the Registration Statement or any material change to such information in the Registration Statement; (2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new Registration Statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering. (b) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 that is incorporated by reference in the Registration Statement shall be deemed to be a new Registration Statement relating to the securities offered herein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (c) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer, or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue. 4 SIGNATURES Pursuant to the requirements of the Securities Act of 1933, the registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-8 and has duly caused this Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Redmond, State of Washington, on this 7th day of August, 1998.

Special Stock Award Program                                            July 1998
- --------------------------------------------------------------------------------

SUMMARY

     The Special Stock Award Program (the "Program") is a program by which
     Microsoft will give shares of Microsoft's stock to key employees of the
     Company.

PURPOSE

     The purpose of the Program is to enable Microsoft to recognize and reward
     key employees for significant achievements and contributions to the
     Company's success.

AWARDS

     Awards under the Program have two components:

 . STOCK BONUS.  The Recipient of an Award will receive registered shares of the
  Company's stock, without cost to the Recipient. The shares are given to the
  Recipient outright, without contingency on continued service and without
  restrictions on transfer.

 . TAX PAYMENT.  Microsoft will calculate all of the Recipient's employment taxes
  associated with this award (e.g., income tax, FICA) and will remit this amount
  to the appropriate taxing agencies on the employee's behalf.

     If the Company determines in its sole discretion that it is illegal or
     inadvisable for it to grant, or for the Key Employee to receive, an Award
     or some component thereof, the Company retains the right to modify the
     Award, to grant fractional Awards, to substitute other legal forms of
     compensation of equal or unequal value, in part or in combination, or to
     grant nothing at all, at its sole discretion.

TOTAL SHARES

     The total number of shares granted during the life of Program, for all
     Awards, will not exceed 250,000 shares of Microsoft common stock.

AWARD SIZE

     No Award may be for less than one share. No Award may be for more shares
     than remain to be granted in the Program (i.e., the maximum number of
     shares set forth in the paragraph above on Total Shares, net any shares
     previously Awarded under the Program). Within these limits, the size of the
     award is at the discretion of the Approvers (defined below).

ELIGIBILITY

     Key employees of the Company are eligible to receive Awards under the
     Program. Key Employees are defined loosely as those executives, managers,
     and individual contributors whose achievements or contributions have been
     or are expected to have a significant effect on the Company's success.

     It is expected that most of the employees who receive Awards under the
     program will have been identified as Key People in the annual review
     process. However, being so identified is not a requirement to receive an
     Award.

PARTICIPATION

     It is anticipated that there will be no greater than 100 awards during any
     fiscal year. However, the number of Awards in a year may exceed 100 so long
     as the total number of shares granted under all Awards under the Program
     does not exceed the total number of shares reserved for the Program, as set
     forth above in the paragraph on Total Shares.

- --------------------------------------------------------------------------------

APPROVERS

     All Awards under the program will be subject to Executive Committee
     approval. All Awards will be granted only by action of the Board of
     Directors or by the Compensation Committee of the Board of Directors
     ("Compensation Committee").

     All awards to Section 16b Executives must be approved by the Compensation
     Committee prior to giving the Award. Post facto ratification of an Award
     to a Section 16b Executive is not sufficient.

IMPLEMENTATION DATE

     The Program will be implemented effective as of July 1, 1998.

     Re:  Microsoft Corporation 1998 Special Stock Award Program

Ladies and Gentlemen:

     We have acted as counsel to Microsoft Corporation (the "Company") in
connection with the registration with the Securities and Exchange Commission on
Form S-8 of shares of Microsoft's common stock, par value $.000025 (the
"Shares"), which will be awarded to certain Microsoft employees under the above-
referenced program (the "Program"). In connection with that registration, we
have reviewed the proceedings of the Board of Directors of Microsoft relating to
the registration and proposed issuance of the common stock, the Articles of
Incorporation of Microsoft and all amendments thereto, the Bylaws of Microsoft
and all amendments thereto, and such other documents and matters as we have
deemed necessary to the rendering of the following opinion.

     Based upon that review, it is our opinion that the Shares when issued in
conformance with the terms and conditions of the Program, will be legally
issued, fully paid, and nonassessable under the Washington Business Corporation
Act.

     We do not find it necessary for the purposes of this opinion to cover, and
accordingly we express no opinion as to, the application of the securities or
blue sky laws of the various states as to the issuance and sale of the Shares.

     We consent to the use of this opinion in the registration statement filed
with the Securities and Exchange Commission in connection with the registration
of the Shares and to the reference to our firm under the heading "Interests of
Named Experts and Counsel" in the registration statement.

                                       Very truly yours,

                         INDEPENDENT AUDITORS' CONSENT
