DIEBOLD ELECTION SYSTEMS MOVING FORWARD AFTER CALIFORNIA SECRETARY OF STATE
ACTION

      McKINNEY, Texas -- Diebold Election Systems (DES) reaffirms its commitment
to support its customer counties in the state of California in their efforts to
conduct a safe, secure and accurate election, in response to the Secretary of
State's action to revoke the conditional certification on the AccuVote-TSX. That
action allows all DES AccuVote-TS units, and other manufacturers' touchscreen
voting machines, upon recertification, to be used in California by voters in the
November election.

      "We are committed to supporting our 19 California customer counties,
including the four affected TSX counties, in their efforts to run an efficient
election in November," said Mark G. Radke, director of marketing for Diebold
Election Systems, Inc. "We have confidence in our technology and its benefits,
and we look forward to helping administer successful elections in California and
elsewhere in the country in November."

      Also, as outlined in the company's response to the recommendation of the
Voting Systems and Procedures Panel (VSPP), submitted April 26, Diebold Election
Systems has been open and forthcoming in its dealings with the Office of the
Secretary of State, as well as with local California elections officials, and
disputes the Secretary of State's accusations. "We plan to continue working in
California in a significant capacity in the future," Radke said. Diebold
Election Systems' full response to the VSPP can be found at

STATE ACTION

      The action by the Secretary of State, as it relates to the TSX, is limited
only to firmware and hardware deployed during the March 2004 primary elections
in Kern, San Diego, San Joaquin and Solano counties. Also, this action has no
effect on the certification status of DES hardware, software and firmware in
other states or jurisdictions throughout the country.

      DES anticipates that its TSX system, which was submitted to the
independent testing authorities nine months ago and successfully completed
federal testing on April 21, 2004, will be the first touchscreen voting system
to be qualified under the new 2002 federal standards. The new TSX system has,
among other improvements, incorporated enhanced security measures. Once
federally qualified, DES plans to work with the state to provide this enhanced
system to the voters of California.
