("AT&T") split off its wholly owned subsidiary Liberty Media Corporation and redeemed, on a one-for-one basis, all of its Liberty Media Group tracking stock, a class of AT&T common stock designed to reflect the performance of AT&T's Liberty Media Group, in exchange for shares of Liberty Media Corporation ("Split Off"). As a result of the Split Off, each holder of a share of AT&T's Class A Liberty Media Group tracking stock received one share Series A Common Stock, and each holder of AT&T's Class B Liberty Media Group tracking stock received one share of Series B Common Stock. The filing person held shares of both AT&T's Class A Liberty Media Group tracking stock and AT&T's Class B Liberty Media Group tracking stock. The number of shares of Series A Common Stock and Series B Common Stock received by the filing person in the Split Off is set forth in more detail in Item 5 hereto. ITEM 4. PURPOSE OF TRANSACTION AT&T SPLIT OFF On August 10, 2001, AT&T completed the Split Off of Liberty Media Corporation pursuant to 3 which AT&T redeemed all of its outstanding shares of Liberty Media Group tracking stock in exchange for shares of Liberty Media Corporation common stock. As a result of the Split Off, holders of AT&T's Liberty Media Group tracking stock received shares of Liberty Media Corporation common stock on the basis of a one-for-one exchange ratio. In addition, Liberty Media Corporation became an independent public company. The reporting person held shares of both AT&T's Class A and Class B Liberty Media Group tracking stocks, and pursuant to the Split Off, received shares of Series A Common Stock and Series B Common Stock, respectively, on the basis of a one-for-one exchange ratio. The approval of the Split Off by the stockholders of AT&T Liberty Media Group tracking stock was not required and was not sought by AT&T. The holders of Series A Common Stock are entitled to one vote for each share held, and the holders of Series B Common Stock are entitled to 10 votes for each share held on all matters voted on by Liberty stockholders, including the election of directors. AGREEMENTS REGARDING COMPANY SECURITIES In 1998, the filing person entered into three agreements with Tele-Communications, Inc. ("TCI") and various other parties which govern the voting and disposition of Company Securities held by the parties to such agreements. The first such agreement (the "Malone Call Agreement") was entered into among TCI, Malone and Malone's wife (together with Malone, the "Malones"), under which the Malones granted to TCI the right to acquire the Malones' high-voting shares, then consisting of an aggregate of approximately 60 million shares of Series B TCI Group Common Stock, TCI Series B Liberty Media Group Common Stock and TCI Series B Ventures Group Common Stock (collectively, the "TCI Series B Shares"), upon Malone's death or upon a contemplated sale of the TCI Series B Shares (other than a minimal amount) to third persons. In either such event, TCI had the right to acquire the shares at a maximum price equal to the then relevant market price of shares of "low-voting" Series A TCI Group Common Stock, TCI Series A Liberty Media Group Common Stock and TCI Series A Ventures Group Common Stock (the "TCI Series A Stock") plus a ten percent premium in the case of the death of Malone or, in the case of a sale of such shares, at the lesser of the price offered for the shares or the market price of the TCI Series A Stock plus a ten percent premium. The Malones also agreed that if TCI were ever to be sold to another entity, then the maximum premium that the Malones would receive on their TCI Series B Shares would be no greater than a ten percent premium over the price paid for the relevant shares of TCI Series A Stock. TCI paid approximately $150 million to the Malones for agreeing to the terms of the Malone Call Agreement. Under the second agreement, the Estate of Betsy Magness Estate and the Bob Magness Estate, Kim Magness, Gary Magness and certain others (collectively, the "Magness Group") entered into a call agreement with TCI (on substantially the same terms as the Malone Call Agreement, including a call on the shares owned by the Magness Group upon Malone's death (the "Magness Call Agreement")), on the Magness Group's aggregate of approximately 49 million TCI Series B Shares. The Magness Group was paid $123,579,980 by TCI for entering into the Magness Call Agreement. The Magness Group entered into a third agreement, the Stockholders' Agreement (the "Stockholders' Agreement"), with the Malones and TCI under which (i) the Magness Group and the Malones agree to consult with each other in connection with matters to be brought to the vote of TCI's shareholders, subject to the proviso that if they cannot mutually agree on how to vote the shares, Malone would have an irrevocable proxy to vote the TCI Series B Shares owned by the Magness Group, (ii) the Magness Group could designate a nominee for the Board and Malone agreed to vote his TCI Series B Shares for such nominee and (iii) certain "tag-along rights" were created in favor of the Magness Group with respect to any sale by the Malones of TCI Series B Shares and certain "drag-along rights" were created in favor of the Malones with respect to the sale of all or substantially all of the TCI Series B Shares beneficially owned by Malone or of the business or assets of TCI, pursuant to which the Magness Group would consent to such sale and, if the sale is of the TCI Series B Shares, the Magness Group would either convert their TCI Series B Shares to the respective TCI Series A Shares of TCI or sell their TCI Series B Shares pursuant to the terms of such sale. 4 In March 1999 in connection with the acquisition of TCI by AT&T, the Magness Group (including FT LLC, Magness LLC, The Kim Magness Family Foundation and The Gary Magness Family Foundation), the Malones, TCI, Liberty Ventures Group LLC and Liberty Media Corporation entered into letter agreements to amend the terms of the Malone Call Agreement ("The Malone Letter Agreement"), the Magness Call Agreement (the "Magness Letter Agreement") and the Stockholders' Agreement (the "Stockholders' Letter Agreement"). Pursuant to the Stockholders' Letter Agreement, the parties thereto agreed to assign TCI's rights and obligations under the Stockholders' Agreement first to Liberty Ventures Group LLC and then to Liberty. In addition, the Stockholders' Letter Agreement amends the Stockholders' Agreement so that the irrevocable proxy to vote shares held by the Magness Group would relate to AT&T's Class B Liberty Media Group tracking stock or any super voting class of equity securities issued by Liberty held by the Magness Group. The "tag-along rights" and "drag-along rights" of the Stockholders' Agreement would relate to the Malones' and the Magness Group's AT&T Class B Liberty Media Group tracking stock or any super voting class of equity securities issued by Liberty and held by the Malones and the Magness Group. As a result of the Split Off, the aforementioned irrevocable proxy and the "tag along" and "drag along" rights now relate to the Series B Common Stock. In addition, since Liberty is now a publicly traded company, the agreement in the Stockholders' Agreement concerning voting of Malone's shares for the Magness Group Representative (as defined in the Stockholders' Agreement) for the Board of Directors will relate to the Board of Directors of Liberty. Pursuant to the Magness Letter Agreement and the Malone Letter Agreement, the parties agreed to assign TCI's rights and obligations under both agreements to Liberty. As a result of the Split Off, the call right under both agreements is now a right on the part of Liberty to purchase the Series B Common Stock upon the following events: (i) a proposed sale by the holder of the Series B Common Stock (other than a minimal amount) or (ii) the death of Malone. This right may be exercised for a maximum price equal to the then relevant market price of "low-voting" Series A Common Stock plus a ten percent premium in the case of the death of Malone or, in the case of a sale of such shares, at the lesser of the price offered for the shares or the market price of the Series A Common Stock plus a ten percent premium. Upon a change in control of Liberty, the maximum premium that the Magness Group or Malones could agree to receive on their Series B Common Stock would be no greater than a ten percent premium over the price paid for the Series A Common Stock. The filing person has no present plan or proposal that relates to or would result in: (a) the acquisition by any person of additional securities of the Company, or the disposition of securities of the Company; except that, although there is no present plan or proposal to dispose of the Company Securities, the personal representative intends to sell or otherwise dispose of the Company Securities (i) as may be required to pay the expenses of administration and other liabilities of the Bob Magness Estate, including the Bob Magness Estate tax liabilities, (ii) as may be required of the personal representative in fulfillment of his fiduciary duties to the Bob Magness Estate, and (iii) as may be required to effect the distribution of the assets of the Bob Magness Estate to the beneficiaries of the Bob Magness Estate; (b) an extraordinary corporate transaction, such as a merger, reorganization, or liquidation, involving the Company or any of its subsidiaries; (c) a sale or transfer of a material amount of assets of the Company or any of its subsidiaries; (d) any change in the present board of directors of the Company or management of the Company, including any plans or proposals to change the number or term of directors or to fill any existing vacancies on the board; (e) any material change in the present capitalization or dividend policy of the Company; (f) any other material change in the Company's business or corporate structure; 5 (g) changes in the Company's certificate of incorporation or bylaws or other actions which may impede the acquisition of control of the Company by any person; (h) causing a class of securities of the Company to be delisted from a national securities exchange or to cease to be authorized to be quoted in an inter-dealer quotation system of a registered national securities association; (i) a class of equity securities of the Company becoming eligible for termination of registration pursuant to Section 12(g)(4) of the Act; or (j) any action similar to any of those enumerated above.
