Ball Corporation’s
(NYSE: BLL) board of directors announced today a two-for-one split of the
company’s common stock and increased the quarterly dividend by 33 percent.
The dividend increase reflects management’s expectations of continued strong
free cash flow generation and earnings performance.

The board also authorized the repurchase by the company of up to a total
of 12 million post-split shares of its common stock. This repurchase
authorization replaces all previous authorizations.

“Since 1999, Ball Corporation’s common stock has returned an average of
25 percent annually and our company has grown diluted earnings per share by
more than 275 percent,” said R. David Hoover, chairman, president and chief
executive officer. “We have generated significant free cash flow, which has
enabled us to make strategic acquisitions, pay down debt, buy back our shares
and increase the dividend we pay to our shareholders. Splitting the stock is
an acknowledgement of that performance.”

The distribution date for the stock split will be Aug. 23, 2004, for
shareholders of record on Aug. 4, 2004. The split is the fourth since Ball
became a public company in 1972, the most recent being in 2002.

The post-split dividend of 10 cents per share is payable Sept. 15, 2004,
to shareholders of record on Sept. 1, 2004, which represents a 33 percent
increase over the previous dividend paid. Ball also increased the dividend in
2002 and in 2003.

Ball Corporation is a supplier of high-quality metal and plastic packaging
products and innovative packaging solutions to the beverage and food

develops sensors, spacecraft, systems and components for government and
commercial markets. Ball employs 12,600 people worldwide and reported 2003
