announced

DUBLIN, Ohio, June 21, 2007 — Cardinal Health, a global provider of products and services that improve the safety and productivity of health care, today announced that more than 80 percent of the outstanding shares of VIASYS Healthcare have been tendered, making VIASYS a majority owned subsidiary of Cardinal Health.

The initial offering period for the tender offer expired at midnight EDT on June 20, with approximately 27.4 million shares of VIASYS common stock being tendered, including approximately 3.2 million shares tendered under guaranteed delivery procedures, for $42.75 per share. All shares that were validly tendered and not withdrawn have been accepted for purchase. Cardinal Health expects to acquire the remaining shares and complete the acquisition by June 30.

“Now that VIASYS is part of Cardinal Health, we are ready to move forward and bring our combined offerings to global customers,” said R. Kerry Clark, chief executive officer of Cardinal Health. “VIASYS is a great strategic fit with Cardinal Health that expands our global presence and provides a new channel to accelerate growth from our other core businesses.”

Subsequent offering and merger
Cardinal Health and its wholly owned subsidiary, Eagle Merger Corp., will commence today a subsequent offering period that will expire at 6 p.m., EDT, on June 27, unless further extended. During this subsequent offering period, VIASYS stockholders who did not previously tender their shares into the offer may do so and will promptly receive the same $42.75 per share cash consideration, without interest, paid during the initial offering period. No shares tendered in the tender offer may be withdrawn during the subsequent offering period.

After expiration of the subsequent offering period, Cardinal Health intends to acquire all of the remaining VIASYS shares by means of a merger at the same price paid in the tender. Upon completion of the merger, VIASYS will become a wholly owned subsidiary of Cardinal Health.
