                                IRREVOCABLE PROXY

         The undersigned stockholder of WM. WRIGLEY, JR. COMPANY, a Delaware
corporation (the "Company"), hereby irrevocably appoints WILLIAM WRIGLEY, JR.,
the attorney and proxy of the undersigned, with full power of substitution, to
the full extent of the undersigned's rights, within the limitations of this
proxy, with respect to shares of the Company's Common Stock and Class B Common
Stock owned of record or beneficially by the undersigned, and any and all other
shares of Wrigley Co. stock issued in respect thereof on or after the date
hereof other than in connection with a Change of Control, as defined in that
certain Proxy and Right of First Offer Agreement dated as of December 14, 2001
by and between the undersigned and William Wrigley, Jr. (the "Agreement")
(collectively, the "Shares"), until such time as the Agreement shall be
terminated in accordance with its terms. Upon the execution hereof, all prior
proxies given by the undersigned with respect to any of the Shares are hereby
revoked and no subsequent proxies will be given. This proxy is irrevocable (to
the extent permitted under Delaware law), is given pursuant to the Agreement and

annual, special or adjourned meeting of the Company's stockholders, or any
written consent in lieu of such a meeting or otherwise.

         The undersigned will, upon request, execute and deliver any additional
documents deemed by the above named attorney and proxy to be necessary or
desirable to effect the irrevocable proxy created hereby.

         Any obligations of the undersigned hereunder shall be binding upon the
successors and assigns of the undersigned. Notwithstanding the foregoing, this
proxy shall not apply to any Shares held by any transferee of the undersigned.
