*On September 14, 1999, Visio Corporation (the "Issuer"), Microsoft Corporation (the "Reporting Person") and MovieSub, Inc. ("Merger Sub"), a wholly owned subsidiary of the Reporting Person, entered into an Agreement and Plan of Reorganization (the "Reorganization Agreement") providing for, among other things, the merger of Merger Sub with and into the Issuer, with the Issuer being the surviving corporation in such merger and becoming a wholly owned subsidiary of the Reporting Person. In connection with the Reorganization Agreement, the Issuer and the Reporting Person entered into a Stock Option Agreement (the "Option Agreement"), dated as of September 14, 1999, pursuant to which the Issuer granted the Reporting Person an option (the "Option") to purchase up to 6,012,500 shares of Common Stock of the Issuer (the "Option Shares"). The Option may only be exercised if a Reorganization Agreement is terminated under certain circumstances set forth in the Reorganization Agreement and the Option Agreement. By reason of its execution of the Option Agreement, the Reporting Person may be deemed to have beneficial ownership of the Option Shares and, accordingly, may be deemed to beneficially own 6,012,500 (or approximately 16.6% of the outstanding Common Stock of the Issuer (based upon the 30,213,572 shares of Visio Common Stock outstanding on September 10, 1999), as represented to Reporting Person by Issuer in the Reorganization Agreement, plus an additional 6,012,500 that Issuer will issue to Reporting Person in the event that the Option is exercised) following the exercise in whole of the Option for 6,012,500 shares of Issuer Common Stock. The Reporting Person expressly disclaims any beneficial ownership of the shares of Issuer Common Stock which are purchasable by the Reporting Person upon exercise of the Option, on the grounds that the Option is not presently exercisable and only becomes exercisable upon the occurrence of the events referred to above. If the Option were exercised, Reporting Person would have the sole right to vote and to dispose of the shares of Issuer issued as a result of such exercise. Neither the filing of this Form 3 nor any of its contents shall be deemed to constitute an admission that the Reporting Person is the beneficial owner of the Option Shares for purposes of Sections 13(d) or 16 of the Securities Exchange Act of 1934, as amended, or for any other purpose and such beneficial ownership is expressly disclaimed. The foregoing summary of the Option Agreement is qualified in its entirely by reference to such agreement, which has been filed as Exhibit 2.2 to the Issuer's Form 8-K dated as of September 15, 1999.
