TERMINATION OF REGISTRATION

     This Post-Effective Amendment No. 1 (this “Post-Effective Amendment”), filed by Perot Systems Corporation, a Delaware corporation (“Perot Systems”), relates to the Registration Statement on Form S-4 (File No. 333-30068) filed by Perot Systems on February 10, 2000 (the “Registration Statement”) with the Securities and Exchange Commission, pertaining to the registration of up to 5,000,000 shares of Perot Systems’ Class A Common Stock, par value $0.01 per share (the “Common Stock”) to be offered and sold in connection with potential future business combinations. As of the date hereof, Perot Systems has issued and sold 3,483,736 shares of Common Stock registered under the Registration Statement.

     On September 20, 2009, Perot Systems entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Dell Inc., a Delaware corporation (“Dell”), and DII – Holdings Inc. (the “Purchaser”), a Delaware corporation and an indirect, wholly-owned subsidiary of Dell, providing for, among other things, the merger of the Purchaser with and into Perot Systems (the “Merger”), with Perot Systems continuing as the surviving corporation and an indirect, wholly-owned subsidiary of Dell. Pursuant to the Merger Agreement, and upon the terms and subject to the conditions thereof, the Purchaser commenced a tender offer (the “Offer”) to purchase all of the shares of Common Stock issued and outstanding (the “Shares”) for $30.00 per Share (the “Offer Price”) without interest thereon and less any applicable withholding or stock transfer taxes. The Offer commenced on October 2, 2009 and expired on November 2, 2009.

     On November 3, 2009, the Merger became effective as a result of the filing of a Certificate of Ownership and Merger with the Secretary of State of the State of Delaware. As a result of the Merger, each Share outstanding immediately prior to the Merger (other than Shares held in the treasury of or reserved for issuance by Perot Systems and Shares owned by Dell or the Purchaser, or direct or indirect wholly-owned subsidiaries of Dell or Perot Systems, all of which were cancelled and extinguished, and any Shares held by stockholders who validly exercise appraisal rights under Delaware law) was automatically converted into the right to receive the Offer Price without interest thereon and less any applicable withholding or stock transfer taxes.

     As a result of the Merger, Perot Systems has terminated all offerings of its securities pursuant to its existing registration statements, including the Registration Statement. In accordance with an undertaking made by Perot Systems to remove from registration, by means of a post-effective amendment, any of the securities registered under the Registration Statement that remain unsold at the termination of the offering, Perot Systems hereby removes from registration all shares of Common Stock registered under the Registration Statement that remain unsold as of the date of this Post-Effective Amendment, consisting of 1,516,264 shares of Common Stock.
