Ball Aerospace & Technologies
Corp. has been awarded one of three risk-reduction study contracts from
Goddard Space Flight Center for the Global Precipitation Measurement —
Microwave Imager (GMI). GMI is an international effort managed by NASA to
improve climate, weather, and hydrological predictions through more accurate
and frequent precipitation measurements.

“GMI represents a great opportunity for Ball Aerospace to enhance our
microwave sensor capability,” said Gary Salisbury, manager of Microwave Sensor
Activities for Civil Space Systems.

GMI will be used to make calibrated, radiometric measurements from space
at multiple microwave frequencies and polarizations. GMI will be placed on the
Global Precipitation Measurement (GPM) Core spacecraft together with the Dual-
frequency Precipitation Radar provided by the National Space Development
Agency of Japan. The Core spacecraft will make radiometric and radar
measurements of clouds and precipitation and will be the central element of
GPM’s space segment.

A second GMI will be placed on the NASA-provided GPM Constellation
spacecraft in order to provide more frequent sampling of precipitation events.
The measurements made by the Core and NASA-provided Constellation spacecraft
will be supplemented with measurements from other microwave radiometers
located on satellites launched and operated by other U.S. agencies and GPM
international partners.

Ball Aerospace & Technologies Corp. provides remote sensing systems and
solutions to the aerospace and defense markets. It is a subsidiary of Ball
Corporation which in addition to owning Ball Aerospace is one of
the leading suppliers of metal and plastic packaging to the beverage and food
industries. With the addition of Ball Packaging Europe, acquired in December
2002, Ball expects sales in 2003 of approximately $5.1 billion, $4.6 billion
from its packaging segment and $500 million from its aerospace and
technologies segment.

Forward-Looking Statements: Forward-Looking Statements:

The information in this news release contains “forward-looking”
statements. Actual results or outcomes may differ materially from those
expressed or implied. As time passes, the relevance and accuracy of
forward-looking statements contained in this release may change. The Company

Please refer to the Form 10-K filed by Ball Corporation on March 27, 2003, for
a summary of key risk factors that could affect actual results or outcomes.
Factors that might affect the Packaging segments or business of the Company
are: fluctuation in consumer and customer demand; competitive packaging
material availability, pricing and substitution; the weather; fruit, vegetable
and fishing yields; company and industry productive capacity and competitive
activity; lack of productivity improvement or production cost reductions;
regulatory action or laws, the German mandatory deposit or other restrictive
packaging legislation, such as recycling laws; availability and cost of raw
materials, energy and transportation; the ability or inability to pass on to
customers changes in these costs, particularly resin, steel and aluminum;
pricing and ability or inability to sell scrap; and international business
risks (including foreign exchange rates) particularly in the United States,
Europe and in developing countries such as China and Brazil. Factors that may
affect the Aerospace segment or business are: funding, authorization and
availability of government contracts and the nature and continuation of those
contracts; and technical uncertainty associated with Aerospace segment
contracts. Factors that could affect the Company as a whole include those
listed plus: successful and unsuccessful acquisitions, joint ventures or
divestitures and the integration activities associated therewith including the
integration and operation of the business of Schmalbach-Lubeca AG, now known
as Ball Packaging Europe; the inability to purchase the Company’s common
stock; regulatory action or laws including those related to corporate
governance and financial reporting, regulations and standards, business
consolidation investment costs and the net realizable value of assets
associated with the Company’s activities; goodwill impairment; changes in
generally accepted accounting principles or their interpretation; litigation;
antitrust, intellectual property, consumer and other issues; strikes;
boycotts; increases in various employee benefits and labor costs, specifically
pension, medical and health care costs incurred in the countries in which Ball
has operations; rates of return projected and earned on assets of the
company’s defined benefit retirement plans; interest rates and level of
company debt; terrorist activities, war or catastrophic events; and U.S. and
foreign economic conditions.
