                                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 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.

                                      -3-

 
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.

Microsoft by Preston Gates & Ellis LLP, 5000 Columbia Center, 701 Fifth Avenue,
