This Amendment No. 2 to the original Schedule 13D filed on October 7, 1996, by SBC Communications Inc. ("SBC") is being filed to reflect a decrease in its indirect holdings in @Track Communications, Inc. (the "Issuer") as described below. Item 1. Security and Issuer This statement relates to the common stock, $0.01 par value (the "Common Stock"), of @Track Communications, Inc. (formerly HighwayMaster Communications, Inc.), a Delaware corporation with its principal executive offices at 1155 Kas Drive, Suite 100, Richardson, Texas 75081. Item 4. Purpose of Transaction On June 4, 2001, SBCW converted 1,000 shares of Series D Preferred Stock into 1,600,000 shares of Common Stock. On June 5, 2001, the Issuer effected a 1-for-5 reverse stock split of its Common Stock, changing SBC's beneficial ownership to 320,000 shares of Common Stock and 1,000,000 Warrants. In addition, the following transactions by the Issuer resulted in further changes to its Common Stock: (i) on June 19, 2001, 12,700,000 shares of Common Stock were issued to holders of the Issuer's 13-3/4% Senior Notes in exchange for the cancellation of such notes, and (ii) on June 21, 2001, the Issuer closed a previously announced transaction and issued 30,000,000 shares of Common Stock to Minorplanet Systems PLC in exchange for $10,000,000. Information regarding these transactions was obtained from press releases and other public filings by the Issuer, and based upon the such information, SBC currently holds less than 5% of the outstanding shares of Common Stock. Item 5. Interest in Securities of the Issuer (a) SBC beneficially owns 320,000 shares of Common Stock and an additional 1,000,000 shares of Common Stock upon the exercise of 1,000,000 Warrants. Assuming the exercise of the Warrants, the total number of shares of outstanding Common Stock that SBC would beneficially own would be 1,320,000, representing 2.7% of the outstanding shares of Common Stock. The Common Stock and Warrants beneficially owned by SBC are owned by and registered in the name of SBC Wireless LLC ("SBCW"). Page 4 of 6 Pages The foregoing percentage is based on the following: Outstanding shares of Common Stock (according to Form 10-Q filed for the period ending March 31, 2001) 25,326,829 Conversion of Series D Preferred Stock 1,600,000 ----------- Total 26,926,829 ---------- Adjusted to reflect 1-for-5 stock split on 6/5/01 5,385,365 Assumption that Warrants are exercised 1,000,000 Common Stock issued to Minorplanet Systems PLC 30,000,000 Common Stock issued to reduce debt 12,700,000 ---------- Outstanding Common Stock as of June 21, 2001 49,085,365 ---------- (b) SBC and SBCW share the power to vote and to dispose of the 320,000 shares of Common Stock and the power to dispose of the 1,000,000 Warrants. The shares of Common Stock and the Warrants, and the shares of Common Stock issuable upon the exercise thereof, beneficially owned by SBCW are subject to certain transfer restrictions described more fully in Items 4 and 6 of the original Schedule 13D filed by SBC on October 7, 1996, and are incorporated herein by reference. (c) On June 4, 2001, SBCW converted 1,000 of Series D Preferred Stock into 320,000 shares of Common Stock (adjusted to reflect a 1-for-5 reverse stock split on June 5, 2001). (d) None. (e) The reporting person ceased to be the beneficial owner of more than 5% of the Issuer's Common Stock on June 21, 2001. Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer On October 2, 2000, SBC and BellSouth Corporation ("BellSouth") formed and contributed to their joint venture called Cingular substantially all of their respective domestic wireless voice and wireless data businesses (including SBC's ownership of SBCW). SBC owns approximately 60% of the outstanding economic interests in Page 5 of 6 Pages Cingular and BellSouth owns approximately 40% of the outstanding economic interests in Cingular, with the remainder of the interest held by the manager of Cingular, Cingular Wireless Management Corp., a Delaware corporation ("Manager"), which is owned equally by SBC and BellSouth. Cingular is managed by Manager, and it is expected that all of the material business decisions for Cingular will be made by the Strategic Review Committee of the Board of Directors of Manager.
