As of June 30, 2003, there were outstanding 184,014,173 shares of Common Stock, no par value, and the aggregate market value of the Common Stock (based upon the closing price of the stock on the New York Stock Exchange on June 30, 2003) held by non-affiliates was approximately $7,548,219,047. As of June 30, 2003, there were outstanding 41,236,449 shares of Class B Common Stock, no par value. Class B Common Stock carries 10 votes per share, is not traded on the exchanges, is restricted as to transfer or other disposition, and is convertible into Common Stock on a share-for-share basis. Upon such conversion, the resulting shares of Common Stock are freely transferable and publicly traded. Assuming all shares of outstanding Class B Common Stock were converted into Common Stock, the aggregate market value of Common Stock held by non-affiliates on June 30, 2003 (based upon the closing price of the stock on the
New York Stock Exchange on such date) would have been approximately $7,873,292,943. Determination of stock ownership by non-affiliates was made solely for the purpose of this requirement, and the Registrant is not bound by these determinations for any other purpose.

As of January 15, 2004, there were outstanding 185,023,269 shares of Common Stock, no par value, and the aggregate market value of the Common Stock (based upon the closing price of the stock on the New York Stock Exchange on January 15, 2004) held by non-affiliates was approximately $7,779,030,884. As of January 15, 2004, there were outstanding 39,854,909 shares of Class B Common Stock, no par value. Class B Common Stock is not traded on the exchanges, is restricted as to transfer or other disposition, and is convertible into Common Stock on a share-for-share basis. Upon such conversion, the resulting shares of Common Stock are freely transferable and publicly traded. Assuming all shares of outstanding Class B Common Stock were converted into Common Stock, the aggregate market value of Common Stock held by non-affiliates on January 15, 2004 (based upon the closing price of the stock on the New York Stock
Exchange on such date) would have been approximately $8,057,475,550. Determination of stock ownership by non-affiliates was made solely for the purpose of this requirement, and the Registrant is not bound by these determinations for any other purpose.

Part IV

Item 15.  Exhibits, Financial Statement Schedule, and Reports on Form 8-K

We are
amending Item 15(a) of the Companys Annual Report on Form 10-K dated
February 9, 2004, for the fiscal year ended December 31, 2003 (the Original
Form 10-K), for the sole purpose of adding the language of Paragraph 4(d)
of Exhibit 31 of Title 17 C.F.R. 229.601(b) (Item 601(b)(31) of Reg.
S-K) to the Section 302 certification of both the Chief Executive Officer
(CEO) and the Chief Financial Officer (CFO) filed as
Exhibits 31(i) and (ii) respectively to the Original Form 10-K. Paragraph 4(d) was
inadvertently omitted when the said Section 302 certifications were filed with
the Original Form 10-K on February 9, 2004.

Accordingly,
we are filing a new currently dated Section 302 certification for each of the
Companys CEO and CFO attached to this Form 10-K/A as Exhibit 31(i) and
(ii) respectively, revised to contain the said omitted language of paragraph
4(d). These new certifications do not contain the language of Paragraph 3 of
Item 601(b)(31) of Reg. S-K, as no new financial statements are included in this
Form 10-K/A.

No revisions
have been made to the Companys financial statements for the 2003 fiscal
year ended December 31, 2003 or any disclosures contained in the Original Form
10-K, including disclosures under Item 9A. The filing of this Form 10-K/A shall
not be deemed an admission that the Original Form 10-K, when filed, knowingly
included any untrue statement of a material fact or omitted to state a material
fact necessary to make a statement not misleading.
