SECURITIES AND EXCHANGE COMMISSION Washington, D.C. 20549 SCHEDULE 13D/A Statement of LIBERTY MEDIA CORPORATION, BARRY DILLER, UNIVERSAL STUDIOS, INC., VIVENDI UNIVERSAL CANADA INC.

Capitalized terms not defined herein have the meanings given to such terms in the prior Reports on Schedule 13D referred to in this paragraph. Information contained herein with respect to each Reporting Person and its executive officers, directors and controlling persons is given solely by such Reporting Person, and no other Reporting Person has responsibility for the accuracy or completeness of information supplied by such other Reporting Person. 11 of 17

ITEM 2. Identity and Background On July 3, 2002, Jean-Rene Fourtou replaced Jean-Marie Messier as Chairman and CEO of Vivendi Universal. Schedules 1 and 5 are incorporated herein by reference and amend and restate Schedules 1 and 5 to the Schedule 13D, respectively, in their entirety. ITEM 3. Source and Amount of Funds or Other Consideration The information contained in Items 5 and 6 of this Schedule 13D is hereby incorporated by reference herein. ITEM 4. Purpose of the Transaction The information contained in Items 5 and 6 of this Schedule 13D is hereby incorporated by reference herein. Depending on market conditions and other factors, and subject to any restrictions described in Items 5 and 6 or contained in the agreements attached as Exhibits hereto or as previously filed as exhibits to this Schedule 13D, the Reporting Persons or their respective subsidiaries may purchase additional shares of Common Stock in the open market or in private transactions. Alternatively, depending on market conditions and other factors, and subject to any restrictions described in Items 5 or 6 or contained in the agreements attached as Exhibits hereto or previously filed as exhibits to this Schedule 13D, the Reporting Persons or their respective subsidiaries may sell all or some of their shares of Common Stock. Except as described in Items 5 and 6 or contained in the agreements attached as Exhibits hereto or previously filed as exhibits to this Schedule 13D, neither any Reporting Person nor, to the best of their knowledge, any of their respective directors or officers has plans or proposals that relate to or would result in any of the actions set forth in clauses (a) through (j) of Item 4. ITEM 5. Interest in Securities of the Issuer The information contained in Item 6 of this Schedule 13D is hereby incorporated by reference herein. The information contained in Item 5 of this Schedule 13D is hereby amended and supplemented by adding the following information: As previously disclosed, the Company and Liberty HSN, Inc., an indirect wholly owned subsidiary of Liberty ("Liberty HSN"), are parties to that certain Exchange Agreement (the "Exchange Agreement"), dated as of December 20, 1996, relating to the exchange, subject to certain restrictions, by Liberty HSN, or its transferee, of shares of common stock of Home Shopping Network, Inc. ("HSN") and shares of Class B common stock of HSN for shares of Common Stock or Class B Common Stock, respectively. Liberty HSN transferred to its wholly owned subsidiary, Liberty HSN II, Inc. ("Liberty HSN II"), 702.66808 shares of common stock of HSN (the "Liberty HSN Common Shares") and 29.56564 shares of Class B common stock of HSN (the "Liberty HSN Class B Shares"), which shares constituted all of the shares of common stock of HSN and Class B common stock of HSN owned by Liberty. Following the sale on August 21, 2001 of its television broadcast stations and associated broadcast licenses (the "Station Sale"), the Company informed Liberty that as a result of the Station Sale, Liberty is permitted under FCC regulations to own shares of Common Stock issuable upon exchange of its HSN shares. On June 27, 2002, the Company and Liberty completed the exchange (the "Exchange") contemplated by the Exchange Agreement. In order to consummate the Exchange, the Company, Liberty, Liberty HSN and Liberty HSN II entered into a separate exchange agreement and Liberty HSN II delivered the Liberty HSN Common Shares and the Liberty HSN Class B Shares to the Company in exchange for an aggregate of 31,620,063 shares of Common Stock and 1,596,544 shares of Class B Common Stock, respectively. 12 of 17

The effect of the Exchange is that Liberty's interest in the Company is now comprised solely of shares of USA, and each of USANi LLC and HSN are direct and indirect wholly owned subsidiaries of USA, thereby simplifying the Company's corporate structure. Because Liberty's HSN shares were exchangeable for USA shares, the transaction described herein did not affect Liberty's ultimate equity ownership interests in the Company. As a result of the consummation of the Exchange, the members of the Reporting Group beneficially own 131,085,373 (assuming the exercise of options to purchase 47,120,888 shares of Common Stock which are currently exercisable by Mr. Diller) shares of Common Stock and 64,629,996 shares of Class B Common Stock. These shares constitute 30.4% of the outstanding Common Stock and 100% of the outstanding Class B Common Stock. Assuming the conversion of all of the Reporting Group's Class B shares into Common Stock, the Reporting Group would beneficially own 39.5% of the outstanding Common Stock (calculated in accordance with Rule 13d-3). Because each share of Class B Common Stock generally is entitled to ten votes per share and each share of Common Stock is entitled to one vote per share, the Reporting Persons may be deemed to beneficially own equity securities of the Company representing approximately 70.5% of the voting power of the Company (or, assuming Mr. Diller does not exercise options to purchase 47,120,888 shares of Common Stock, approximately 69.1% of the voting power of the Company). The foregoing beneficial ownership figures exclude shares of Common Stock beneficially owned by Diane Von Furstenberg, Mr. Diller's spouse, as to which Mr. Diller disclaims beneficial ownership. Mr. Diller continues to hold an irrevocable proxy granted by each of Universal and Liberty, pursuant to which Mr. Diller has the right to vote the Company's securities held by Universal, Liberty and their respective affiliates. The shares of Common Stock and Class B Common Stock received by Liberty pursuant to the Exchange are subject to the irrevocable proxy held by Mr. Diller. Jerome H. Kern, a Director of Liberty, owns 11,000 shares of Common Stock. David J.A. Flowers, Senior Vice President and Treasurer of Liberty, owns 1,020 shares of Common Stock. On May 20, 2002, the Diller-Von Furstenberg Family Foundation, a private foundation as to which Mr. Diller disclaims beneficial ownership, sold in the open market 42,000 shares of Common Stock at $28.784 per share. Except as set forth or incorporated by reference herein, no Reporting Person or, to the best knowledge of each Reporting Person, any executive officer or director of such Reporting Person has effected any transaction in the Common Stock during the past 60 days. ITEM 6. Contracts, Arrangements, Understandings, or Relationships with Respect to the Securities of the Issuer. The information contained in Item 5 of this Schedule 13D is hereby incorporated by reference herein. ITEM 7. Materials to be Filed as Exhibits The information contained in Item 7 of the Schedule 13D is hereby amended and supplemented by adding the following information: The following document is filed as an exhibit to this statement: 50. Exchange Agreement by and among the Company, Liberty Media Corporation, Liberty HSN II, Inc. and Liberty HSN, Inc., dated as of June 27, 2002. 13 of 17

(i) USAi hereby covenants and agrees that so long as Liberty (A) does not increase its percentage ownership of USAi's combined equity and debt (calculated in accordance with the Communications Act and the FCC Regulations) (other than any such increase which occurs pursuant to the terms of the Shareholder Arrangements or any other arrangements to which USAi and Liberty are parties or as a result of actions taken by USAi or its subsidiaries), and (B) Beneficially Owns (as defined in the Governance Agreement) at least two-thirds of the number of Equity Securities (as defined in the Governance Agreement) Beneficially Owned by it immediately prior to February 12, 1998 (appropriately adjusted to reflect any stock splits and the like), it will not (and will not cause or permit any of its subsidiaries to) take any action in connection with or relating to the Esperanza Transaction that would reasonably be expected to, or fail to take any action in connection with or relating to the Esperanza Transaction which failure would reasonably be expected to, make the ownership by Liberty, Liberty HSN or Liberty HSN II of the Exchange Shares or any other material assets of such persons (including specifically (but without limiting the foregoing) Liberty's ownership interest in certain cable television systems and related businesses located in the Commonwealth of Puerto Rico) unlawful or result in a violation of any law, rule, regulation, order or decree (including, but not limited to, the Communications Act and the FCC Regulations) or impose material additional restrictions or limitations on such person's full rights of ownership of the Exchange Shares or the ownership of its other material assets or the operation of its businesses (provided, that for purposes of this Section 5a(i), to the extent that a condition, restriction or limitation upon USAi or its subsidiaries, in each case in connection with or relating to the Esperanza Transaction, relates to or is based upon or would arise as a result of, any action or the consummation of a transaction by the Liberty Group, such condition, restriction or limitation shall be deemed to be such a condition, restriction or limitation on the Liberty Group (regardless of whether a member of the Liberty Group (as defined herein) is a party to or otherwise would be legally obligated thereby) to the extent that the taking of an action or the consummation of a transaction by the Liberty Group would result in USAi, any BDTV Entity or any of their respective subsidiaries being in breach or violation of any law, rule, regulation, order or decree or otherwise causing such rule, regulation, order or decree to terminate or expire or would otherwise result in Liberty's beneficial ownership of the Exchange Shares or any other material assets being illegal or in violation of any law, rule, regulation, order or decree); provided, however, that neither USAi nor any of its subsidiaries shall be required to take any action (or fail to act) pursuant to this Section 5a(i) if such action (or failure to act) would not reasonably be expected to have the effects described in this Section 5a(i) (except as a result of the single majority shareholder exception to the FCC's broadcast attribution rules (47 C.F.R. Section 73.3555 note 2(b)) if such actions (or failure to act) had been taken (or failed to be taken) on the date hereof. (ii) USAi hereby covenants and agrees that, so long as Liberty (A) does not increase its percentage ownership of USAi's combined equity and debt (calculated in accordance with the Communications Act and the FCC Regulations) (other than any such increase which occurs pursuant to the terms of the Shareholder Arrangements or any -8-

other arrangements to which USAi and Liberty are parties or as a result of actions taken by USAi or its subsidiaries), and (B) Beneficially Owns at least two-thirds of the number of Equity Securities Beneficially Owned by it immediately prior to February 12, 1998 (appropriately adjusted to reflect any stock splits and the like), it will not (and will not cause or permit any of its subsidiaries to) take any action that would reasonably be expected to make the ownership by Liberty, Liberty HSN or Liberty HSN II of the Exchange Shares or any other material assets of such persons result, at the time such action is taken by USAi, in a violation of the FCC's broadcast-cable cross ownership rule. Without limiting the generality of the foregoing, the closing by USAi of a transaction (other than the Esperanza Transaction) otherwise prohibited by this Section 5a(ii) shall be deemed permissible under this Section if at the time USAi entered into a binding agreement relating to such transaction, such transaction would have been permissible under (x) this Section 5a(ii) (except for the single majority shareholder exception to the FCC's broadcast attribution rules (47 C.F.R. Section 73.3555 note 2(b)) and (y), if applicable, any revision to the attribution and/or cable-broadcast cross ownership rule(s) which has been proposed in a formal notice of proposed rule making that is pending at such time and publicly released by the FCC prior to such time. (iii) USAi hereby agrees to reimburse Liberty and the members of the Liberty Group for their reasonable expenses, including attorneys fees, incurred in connection with any relevant FCC inquiry or proceeding to the extent relating to the Exchange or the matters set forth in Section 5a(i). Any such reimbursement obligation shall be satisfied by USAi by the delivery to Liberty of shares of USAi Common Stock having an aggregate value equal to the amount of such reimbursement obligation. b. (i) Excluding actions specifically contemplated by the Exchange Agreement and the Merger Agreement (as defined in the Exchange Agreement), without the prior written consent of Liberty following the date of this Agreement (which consent will not be unreasonably withheld, provided that the notice soliciting such consent includes (A) a specific statement that such consent is given pursuant to this Section 5b(i) and (B) a reasonably detailed description of each material aspect of the action, or failure to act, to be consented to), USAi will not (and will not permit any of its subsidiaries to) take any action that would or could reasonably be expected to, or fail to take any action which failure would or could reasonably be expected to, cause the Exchange to be a taxable transaction to any Liberty Party; provided, however, that if the Exchange is taxable to any Liberty Party as a result of (1) any action or failure to act by any Liberty Party (other than due to an action or inaction by the Liberty Group or such Liberty Party specifically contemplated or required by the Exchange Agreement, the Merger Agreement or the Shareholder Arrangements), (2) the laws and regulations in effect at the effective time of the merger of House Acquisition Corp. and HSN or (3) any difference in the tax position of Liberty HSN II relative to the tax position of Liberty HSN, compliance with the covenant set forth in this Section 5b(i) shall be deemed waived by the Liberty Parties with respect to the Exchange and provided, further, that if the taxes applicable to the Exchange would have been accrued or been payable by Liberty HSN had all the Exchange Shares been issued to Liberty HSN at the effective time of the merger of House Acquisition Corp. and HSN, then compliance with the covenant set forth in this Section 5b(i) shall be deemed waived by the Liberty Parties. The term "Liberty Group" shall mean Liberty and its controlled Affiliates, including Liberty HSN and Liberty HSN II. -9-

(ii) In the event that the Exchange is taxable to Liberty, Liberty HSN II or any of their respective Affiliates as a result of a change in law or regulation after the effective time of the merger of House Acquisition Corp. and HSN, a breach of any of the representations and warranties set forth in Section 3e or any of the covenants of USAi set forth in Section 5b(i) and the last sentence of Section 1 or any action taken by USAi after the effective time of the merger of House Acquisition Corp. and HSN (other than any tax liability that results from (x) any breach by Liberty of the covenants set forth in the last sentence of Section 1 or (y) an action or unreasonable inaction by the Liberty Group (other than due to an action or inaction specifically contemplated or required by the Exchange Agreement, the Merger Agreement or the Shareholder Arrangements)), USAi shall be obligated to issue to Liberty HSN II a number of additional shares of USAi Common Stock sufficient on an after-tax basis, to pay any resulting taxes; provided, however, that USAi shall have no obligation under this -------- ------- Section 5b(ii) to the extent that the Exchange is taxable to Liberty, Liberty HSN II or any of their respective Affiliates solely as a result of any difference in the tax position of Liberty HSN II relative to the tax position of Liberty HSN. (iii) Any shares of USAi Common Stock deliverable by USAi pursuant to Section 5a(iii) or 5b shall be valued based on the average of the daily closing prices (as of 4:00 p.m. eastern time) per share of USAi Common Stock as reported on the Nasdaq Stock Market (as published in The Wall Street Journal or, if not published therein or incorrectly published therein, in another authoritative source mutually selected by USAi and Liberty) for the ten consecutive trading days ending on the second trading day prior to the date of the Closing. All such shares of USAi Common Stock issued pursuant to this Section 5b shall be duly authorized, fully paid, and non-assessable and shall be deemed for all purposes hereunder to be Exchange Shares. Whenever it is necessary for purposes of this Agreement to determine whether the Exchange is taxable or tax-free, such determination shall be made with respect to the Code, without regard to any interest imputed under Section 483 of the Code. For purposes of this Agreement, a Person's "tax position" shall not include or take into account any offsets against any tax which are peculiar to such Person (such as tax credits, loss carry-overs, and current losses). c. The parties hereto agree that irreparable damage would occur in the event that the covenants or agreements in this Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that, in addition to any other remedy to which they are entitled at law or in equity, the parties hereto shall be entitled to an injunction, temporary restraining order or other equitable relief enjoining such breach and enforcing specifically the terms and provisions hereof; provided, however, that neither any member of the Liberty Group nor USAi shall seek a remedy that would cause the Exchange to be a taxable transaction. 6. Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of Delaware, without regard to the conflict of laws principles thereof. Each party hereto irrevocably submits to the jurisdiction of any Delaware state court or any federal court sitting in the State of Delaware in any action arising out of or relating to this Agreement, and hereby irrevocably agrees that all claims in respect of such action may be heard and determined in such Delaware state or federal court. Each party hereto hereby irrevocably waives, to the fullest extent it may effectively do so, the defense of an inconvenient forum to the maintenance of such action or proceeding. The parties hereto further agree, to the -10-

extent permitted by law, that final and unappealable judgment against any of them in any action or proceeding contemplated above shall be conclusive and may be enforced in any other jurisdiction within or outside the United States by suit on the judgment, a certified copy of which shall be conclusive evidence of the fact and amount of such judgment. Each party hereto waives, to the fullest extent permitted by applicable laws, any right it may have to a trial by jury in respect of any action, suit or proceeding arising out of or relating to this Agreement. Each party hereto certifies that it has been induced to enter into this Agreement by, among other things, the mutual waivers and certifications set forth above in this Section 6. 7. Counterparts. This Agreement may be executed simultaneously in two or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. 8. Assignment; Binding Effect; Benefit. Neither this Agreement nor any of the rights, benefits or obligations hereunder may be assigned by a party without the prior written consent of the other parties hereto. For purposes of this Agreement, the written consent of Liberty shall constitute the written consent of each of Liberty, Liberty HSN and Liberty HSN II. This Agreement will be binding upon, inure to the benefit of and be enforceable by the parties and their respective successors and assigns. Nothing in this Agreement, expressed or implied, is intended to confer on any person other than the parties or their respective successors and assigns, any rights, remedies, obligations or liabilities under or by reason of this Agreement. 9. Survival. The representations and warranties set forth in Section 3c(i), 3e, 3f and 4b shall survive the Closing. All other representations and warranties shall terminate upon the Closing. All of the covenants and agreements set forth in this Agreement shall survive the Closing in accordance with their terms. 10. Notices. All notices, requests, demands, waivers and other communications required or permitted to be made hereunder shall be made in the manner set forth in the Exchange Agreement. 11. Definitions. Capitalized terms used but not defined herein shall have the meanings attributed to such terms in the Exchange Agreement. -11-

EXHIBIT A DETAILS FOR EXCHANGE Since the Pre-Merger Exchange in December 1996, the only events affecting USAi or HSN which require adjustments to the Common Exchange Ratio and the Class B Exchange Ratio are those listed in this Exhibit A. The change in the number of HSN shares held by Liberty and the change in the Common Exchange Ratio and the Class B Exchange Ratio since the Pre-Merger Exchange are the result of the March 1998 USAi 2 for 1 stock split, the June 1998 HSN 25,000 to 1 reverse stock split and the February 2000 USAi 2 for 1 stock split. No other adjustments were made (or required to be made) to the share numbers or exchange ratios.
