Item 5. Other Events.

      On April 27, 1999, the stockholders of the company approved amendments to
the Certificate of Incorporation to increase the number of authorized shares of
common stock from 1,875 million to 4,687.5 million and to effect a two-for-one
stock split approved by the company's Board of Directors on January 26, 1999. In
addition, the amendments served to reduce the par value of the common shares
from $.50 per share to $.20 per share.

      Common stockholders of record at the close of business on May 10, 1999
will receive one additional share for each share held. Distribution of the
additional shares is expected to occur on May 26, 1999, and will be effected in
book-entry form, through the mailing of an account statement to each stockholder
of record as of the stock split record date, thereby crediting the additional
shares of common stock due as a result of the stock split stock split.

Stock options to purchase 4,124,730* shares in 1998, 331,666* shares in 1997 and
1,568,282* shares in 1996 were outstanding, but were not included in the
calculation of diluted earnings per share because the options' exercise price
was greater than the average market price of the common shares, and therefore,
the effect would be anti-dilutive. In addition, 5,131,038* restricted stock
units in 1998 relating to the company's Long-Term Performance Plan were not
included in the computation of diluted earnings as their effect would be
anti-dilutive.
