Item 4. Purpose of the Transaction.

     Item 4 of the Schedule 13D is hereby amended and supplemented by adding the following paragraphs at the end thereof:

     The Supplemental Marketing Agreement and Waiver, dated June 23, 2004. On June 23, 2004, Diageo, DAHBV (as successor in interest to Gramet Holdings Corp.) and General Mills entered into a Supplemental Marketing Agreement and Waiver (“SMA”).

     Under the terms of the SMA, we and General Mills have agreed, until the first anniversary of the effectiveness of the registration statement filed by General Mills on June 23, 2004 registering 49,907,680 of our shares of General Mills stock (the “Registration Statement”), to work in good faith toward the implementation of a transaction to sell 49,907,680 shares of General Mills common stock, or any smaller number agreed to by General Mills and Diageo, currently owned by us. The agreement further contemplates that:

     However, Diageo has the right to sell all 49,907,680 shares, or any smaller number agreed to by us and General Mills, directly through a block trade to an underwriter or syndicate of underwriters for resale to the public, subject to the right of General Mills to match the price offered by that underwriter and purchase those shares itself. The SMA provides that Diageo will not sell shares under the Registration Statement except in the transactions outlined above. Any other transaction under the Registration Statement would require the consent of General Mills.

     Under the SMA, General Mills agreed to file the Registration Statement, and to include in the Registration Statement 49,907,680 General Mills common shares held by Diageo. The inclusion of these shares was in lieu of any “piggyback” registration rights that Diageo might otherwise have had with respect to the Registration Statement. The SMA does not affect any of Diageo’s other registration rights under the Stockholders Agreement or otherwise affect its ability to sell the Shares in accordance with that agreement. Until the transaction described above is completed, or until Diageo otherwise sells the identified 49,907,680 shares, General Mills has agreed not to sell any equity securities under the Registration Statement without Diageo’s consent.

     Following the first anniversary of the effective date of the Registration Statement, General Mills has the right to deregister the offering of shares by Diageo. This right is subject to the agreement of General Mills not to offer or sell any shares of common stock under the Registration Statement until Diageo has otherwise disposed of at least 49,907,680 General Mills common shares. General Mills will also deregister the shares at Diageo’s request.

     The descriptions of the SMA in this item and throughout this Amendment No. 3 are qualified in their entirety by reference to the SMA, a copy of which is attached hereto as Exhibit (i).

     In connection with the execution of the SMA and the filing of the Registration Statement, Diageo’s representatives on the Board of Directors of General Mills resigned on June 23, 2004, and on that same day Diageo, DAHBV and General Mills executed an amendment to the Stockholders Agreement permanently eliminating Diageo’s right thereunder to representation on the Board

of Directors of General Mills. The descriptions of this amendment to the Stockholders Agreement throughout this Amendment No. 3 are qualified in their entirety by reference to the amendment, a copy of which is attached hereto as Exhibit (j).

Item 5. Interest in Securities of the Issuer.

     Item 5 of the Schedule 13D is hereby amended by replacing the second sentence of the first paragraph of Item 5 with the following:

     Following completion of the sale to the Company of the Put Shares, as discussed below, the Reporting Persons own the Shares which represent approximately 20.8% of the Common Stock outstanding, based on 379,543,998 shares of Common Stock outstanding as of May 30, 2004 (as reported by General Mills in the Registration Statement).

     Item 6 of the Schedule 13D is hereby amended and supplemented by adding the following at the end thereof:

     As more fully described in Item 4 above, Diageo, DAHBV and General Mills are parties to a Supplemental Marketing Agreement and Waiver. A copy of the Supplemental Marketing Agreement and Waiver is attached hereto as Exhibit (i).

     As more fully described in Item 4 above, Diageo, DAHBV and General Mills have executed an amendment to the Stockholders Agreement permanently eliminating Diageo’s right thereunder to representation on the Board of Directors of General Mills. A copy of this amendment to the Stockholders Agreement is attached hereto as Exhibit (j).

Item 7. Material to be filed as Exhibits.
