Except as specifically amended hereby, all other provisions of Mr. Wrigley, Jr.’s Schedule 13D filed on April 8, 1999, as amended by Amendment Nos. 1-8, remain in full force and effect. Capitalized terms used herein and not otherwise defined shall have the same meanings ascribed to them in such Schedule 13D.

Item 3. Source and Amount of Funds or Other Consideration.

See response to Item 4 below.

Item 4. Purpose of Transaction.

On May 1, 2006, the Company distributed to all stockholders of record a one-time 5-for-4 stock dividend in which one share of Class B Common Stock was issued for every four shares of Common Stock and one share of Class B Common Stock was issued for every four shares of Class B Common Stock, in each case, held as of the close of business on April 17, 2006. As a result of the stock dividend, Mr. Wrigley, Jr. became the beneficial owner (prior to the disclaimer of beneficial interest as described herein) of an additional 8,504,173 shares of Class B Common Stock.

Item 5. Interest in Securities of the Issuer.

(a) Mr. Wrigley, Jr. is the beneficial owner (prior to the disclaimer of beneficial interest as described herein) of 14,252,502 shares of Common Stock, representing 7.5% of the issued and outstanding shares of Common Stock, and 28,268,405 shares of Class B Common Stock, representing 31.9% of the issued and outstanding shares of Class B Common Stock. Of these Shares, Mr. Wrigley, Jr. disclaims any beneficial interest in 13,365,831 shares of Common Stock and 12,627,679 shares of Class B Common Stock. Shares of Class B Common Stock are entitled to ten votes per share, are subject to restrictions on transfer and are convertible at any time at the option of the holder into shares of Common Stock on a share-for-share basis. Pursuant to Rule 13d-3(d)(1)(i)(B) under the Securities Exchange Act of 1934, Mr. Wrigley, Jr. is deemed to beneficially own 42,520,907 shares of Common Stock, representing 19.6% of the issued and outstanding shares of Common Stock, after giving effect to the assumed conversion by Mr. Wrigley, Jr. of the shares of Class B Common Stock (but not giving effect to the assumed conversion of the other outstanding shares of Class B Common Stock). Assuming conversion of all outstanding shares of Class B Common Stock (including those beneficially owned by Mr. Wrigley, Jr.) the 42,520,907 shares of Common Stock deemed beneficially owned by Mr. Wrigley, Jr. would represent 15.3% of the deemed issued and outstanding shares of Common Stock. The ownership percentages set forth herein are based upon 188,937,249 shares of Common Stock and 88,562,539 shares of Class B Common Stock outstanding as of May 1, 2006, as disclosed by the Company.
