(1) Each of the 32,377,940 outstanding shares of Series D Preferred Stock held by Microsoft Corporation ("Microsoft") prior to the closing of the firm commitment initial public offering ("IPO") by Facebook, Inc. ("Facebook") is convertible into 1.012561 shares of Class B Common Stock at any time and this conversion right has no expiration date; the Class B Common Stock is convertible into shares of Class A Common Stock at any time on a one-for-one basis and this conversion right has no expiration date. This filing is made as a result of Microsoft's beneficial ownership of such underlying shares of Class A Common Stock as determined in accordance with the rules of the Securities and Exchange Commission.
 
Remarks:
Following the closing of the IPO, Microsoft will no longer be a 10% beneficial owner of any class of equity security of Facebook registered under Section 12 of the Securities Exchange Act of 1934, as amended, and, therefore, will no longer be subject to Section 16 of such Act. In addition, Microsoft plans to file a Form 4 following the closing of the IPO which reflects, as of such closing, the automatic conversion of Microsoft's Series D Preferred Stock into shares of Class B Common Stock, Microsoft's subsequent conversion of certain of such shares of Class B Common Stock into shares of Class A Common Stock, and Microsoft's subsequent sale of such shares of Class A Common Stock in connection with the IPO.
