                                  THE COMPANY
                                        
     Microsoft was founded as a partnership in 1975 and incorporated in 1981.
Microsoft develops, manufactures, licenses, sells, and supports a wide range of
software products, including operating systems for personal computers ("PCs")
and servers; server applications for client/server environments; business and
consumer productivity applications; software development tools; and Internet and
intranet software and technologies. Microsoft has recently expanded its
interactive content efforts, including MSN(TM), The Microsoft Network online
service, various Internet-based services, and entertainment and information
software programs. Microsoft also sells personal computer books and input
devices and researches and develops advanced technologies for future software
products. Microsoft's business strategy emphasizes the development of a broad
line of PC and server software products for business and personal use, marketed

                                USE OF PROCEEDS
                                        
     Microsoft will not receive any proceeds from the sale of the Common Shares
offered hereby; nor will such proceeds be available for Microsoft's use or
benefit.

                             SELLING SHAREHOLDERS
                                        
     All of the Common Shares described in this Prospectus will be owned
immediately after registration by the Selling Shareholders. All of the shares
offered by the Selling Shareholders were acquired in connection with the Merger.
Such shares do not exceed one percent (1%) of Microsoft's outstanding
capitalization. None of the Selling Shareholders has a material relationship
with Microsoft, except that certain Selling Shareholders are or will be non-
officer employees of Valence or Microsoft.

                             PLAN OF DISTRIBUTION
                                        
     Microsoft has been advised by each Selling Shareholder that, subject to the
terms of the Investment Agreement, each Selling Shareholder expects to offer
his, her, or its Common Shares to or through brokers and dealers and
underwriters to be selected by the Selling Shareholder from time to time. In
addition, the Common Shares may be offered for sale through the Nasdaq Stock
Market, in the over-the-counter market, through a market maker, in one or more
private transactions, or a combination of such methods of sale, at prices and on
terms then prevailing, at prices related to such prices, or at negotiated
prices. Each Selling Shareholder may pledge all or a portion of the Common
Shares owned by him, her or it as collateral in loan transactions. Upon default
by any such Selling Shareholder, the pledgee in such loan transaction would have
the same rights of sale as such Selling Shareholder under this Prospectus. Each
Selling Shareholder also may enter into exchange traded listed option
transactions that require the delivery of the Common Shares listed hereunder.
Subject to the terms of the Investment Agreement, each Selling Shareholder may
also transfer Common Shares owned by him, her or it in other ways not involving
market makers or established trading markets, including directly by gift,
distribution, or other transfer without consideration, and upon any such
transfer the transferee would have the same rights of sale as such

                                      -3-

 
Selling Shareholder under this Prospectus. In addition, any securities covered
by this Prospectus that qualify for sale pursuant to Rule 144 of the 1933 Act,
and may be sold under Rule 144 rather than pursuant to this Prospectus. Finally,
each Selling Shareholder and any brokers and dealers through whom sales of the
Common Shares are made may be deemed to be "underwriters" within the meaning of
the 1933 Act, and the commissions or discounts and other compensation paid to
such persons may be regarded as underwriters' compensation.

                                 LEGAL MATTERS

     The validity of the Common Shares offered hereby will be passed upon for
Microsoft by Preston Gates & Ellis LLP, 5000 Columbia Center, 701 Fifth Avenue,
Seattle, Washington 98104. As of the date hereof, attorneys in Preston Gates &
Ellis LLP who have worked on substantive matters for Microsoft own less than
500,000 Common Shares.

                 Total                              $18,977.05
     

Item 15.  Indemnification of Directors and Officers.
- --------------------------------------------------- 

     Article XII of the Restated Articles of Incorporation of Microsoft
authorizes Microsoft to indemnify any present or former director or officer to
the fullest extent not prohibited by the WBCA, public policy or other applicable
law. Chapter 23B.8.510 and .570 of the WBCA 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.

     The directors and officers of Microsoft are entitled to indemnification by
each of the Selling Shareholders against any cause of action, loss, claim,
damage, or liability to the extent it arises out of or is based upon the failure
of any Selling Shareholder (or his donees, legatees, or pledgees) and each
underwriter to comply with the Prospectus delivery requirements under the
federal securities laws or any applicable state securities laws or upon any
untrue statement or alleged untrue statement or omission or alleged omission
made in this Registration Statement and the Prospectus contained herein, as the
same shall be amended or supplemented, made in reliance upon or in conformity
with written information furnished to Microsoft by such Selling Shareholder or
such underwriter.

     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 16.  List of Exhibits.
- -------------------------- 

     The Exhibits to this registration statement are listed in the Index to
Exhibits on page II-4.

Item 17.  Undertakings.
- ---------------------- 

     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:

          (i) To include any prospectus required by section 10(a)(3) of the
     1933 Act;

          (ii) To reflect in the prospectus any facts or events arising after
     the effective date of this registration statement (or the most recent post-
     effective amendment thereof) that, individually or in the

                                      II-1

 
     aggregate, represent a fundamental change in the information set forth in
     this registration statement. Notwithstanding the foregoing, any increase or
     decrease in volume of securities offered (if the total dollar value of
     securities offered would not exceed that which was registered) and any
     deviation from the low or high end of the estimated maximum offering range
     may be reflected in the form of prospectus filed with the Commission
     pursuant to Rule 424(b) if, in the aggregate, the changes in volume and
     price represent no more than a 20% change in the maximum aggregate offering
     price set forth in the "Calculation of Registration Fee" table in the
     effective registration statement;

          (iii)  To include any material information with respect to the plan
     of distribution not previously disclosed in this registration statement or
     any material change to such information in this registration statement;

provided, however, that paragraphs (1)(i) and (1)(ii) do not apply if the
information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed by Microsoft pursuant to
Section 13 or Section 15(d) of the Exchange Act that are incorporated by
reference in this registration statement.

     (2)  That, for the purpose of determining any liability under the 1933 Act,
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 that remain unsold at the termination of the
offering.

     (4)  For purposes of determining any liability under the 1933 Act, each
filing of the registrant's annual report pursuant to Section 13(a) or Section
15(d) of the Exchange Act (and, where applicable, each filing of an employee
benefit plan's annual report pursuant to Section 15(d) of the Exchange Act) that
is incorporated by reference in the registration statement 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.

     (5)  Insofar as indemnification for liabilities arising under the
Securities Act of 1933 Act 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 1933 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
