Tendering stockholders who have Shares registered in their names and who tender directly to Computershare Trust Company, N.A., as depositary for the Offer (the “Depositary”), will not be charged brokerage fees or commissions or, subject to Instruction 6 of the Letter of Transmittal, transfer taxes on the purchase of Shares pursuant to the Offer. Stockholders who hold their Shares through a broker or bank should consult such institution as to whether it charges any such fees or commissions.

THE OFFER AND WITHDRAWAL RIGHTS WILL EXPIRE AT 12:00 MIDNIGHT, NEW

YORK CITY TIME, AT THE END OF WEDNESDAY, JUNE 20, 2007, UNLESS THE OFFER IS

EXTENDED.

The Offer is conditioned upon, among other things, (1) there being validly tendered and not properly withdrawn prior to the expiration of the Offer a number of Shares that represents at least a majority of the total number of outstanding Shares on a fully diluted basis (the “Minimum Condition”), and (2) any applicable waiting period (and any extension thereof) under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, or any applicable required approvals of the

competent competition authority of any member state of the European Union having been obtained or terminated, or having expired, as the case may be. The Offer also is subject to other conditions set forth in the Offer to Purchase. See Section 14—“Conditions of the Offer” of the Offer to Purchase.

The Offer is being made pursuant to the Agreement and Plan of Merger, dated as of May 11, 2007, among Cardinal Health, Offeror and VIASYS (the “Merger Agreement”). The Merger Agreement provides, among other things, for the making of the Offer by Offeror, and further provides that, following the completion of the Offer, upon the terms and subject to the conditions of the Merger Agreement and in accordance with the Delaware General Corporation Law (the “DGCL”), Offeror will be merged with and into VIASYS (the “Merger”). Following the effective time of the Merger (the “Effective Time”), VIASYS will continue as the surviving corporation (the “Surviving Corporation”) and become a wholly owned subsidiary of Cardinal Health, and the separate corporate existence of Offeror will cease. At the Effective Time, each Share issued and outstanding immediately prior to the Effective Time (other than (1) any Shares directly owned by VIASYS, Cardinal Health or Offeror, and (2) Shares, if any, held by stockholders who have properly exercised appraisal rights under Section 262 of the DGCL) will, by virtue of the Merger and without any action on the part of the holders of the Shares, be canceled and cease to exist, and will be converted into the right to receive in cash the Offer Price, payable to the holder thereof, without interest, upon surrender of the certificate or certificates formerly representing such Shares, less any required withholding taxes.

The Board of Directors of VIASYS has unanimously (1) approved the Merger Agreement, and deemed the Merger Agreement, the Offer, the Merger and the transactions contemplated by the Merger Agreement advisable, fair to and in the best interests of VIASYS and the VIASYS stockholders, (2) approved and adopted the Merger Agreement and the transactions contemplated by the Merger Agreement, including the Offer and the Merger, and (3) recommended that the VIASYS stockholders accept the Offer and tender their VIASYS shares under the Offer to Offeror.

For purposes of the Offer, Offeror will be deemed to have accepted for payment (and thereby purchased) Shares validly tendered and not properly withdrawn as, if and when Offeror gives oral or written notice to the Depositary of Offeror’s acceptance for payment of such Shares pursuant to the Offer. Upon the terms and subject to the conditions of the Offer, payment for Shares accepted for payment pursuant to the Offer will be made by deposit of the purchase price therefor with the Depositary, which will act as agent for tendering stockholders for the purpose of receiving payments from Offeror and transmitting such payments to stockholders whose Shares have been accepted for payment. In all cases, payment for Shares tendered and accepted for payment pursuant to the Offer will be made only after timely receipt by the Depositary of (1) certificates representing such Shares, or timely confirmation of a book-entry transfer of such Shares into the Depositary’s account at the Book-Entry Transfer Facility (as defined in the Offer to Purchase) pursuant to the procedures set forth in Section 3 of the Offer to Purchase, (2) the Letter of Transmittal (or a facsimile thereof), properly completed and duly executed, with any required signature guarantees, or an Agent’s Message (as defined in the Offer to Purchase) in connection with a book-entry transfer, and (3) any other documents required by the Letter of Transmittal.

Subject to the provisions of the Merger Agreement and the applicable rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”), Offeror may, without the consent of VIASYS, (1) extend the Offer for one or more periods of not more than five business days if, at the scheduled Expiration Date (as defined below), any of the conditions of the Offer (see Section 14 of the Offer to Purchase) will not have been satisfied or waived, (2) extend the Offer for any period required by any rule, regulation, interpretation or position of the SEC or the staff of the SEC applicable to the Offer or (3) if all of the conditions of the Offer are satisfied but the number of Shares validly tendered and not withdrawn in the Offer, together with any shares of VIASYS common stock then owned by Cardinal Health, is less than 90% of the outstanding shares of VIASYS common stock, commence a subsequent offering period for three to 20 business days for the remaining outstanding Shares.

Any extension, delay, termination, waiver or amendment will be followed as promptly as practicable by public announcement thereof to be made no later than 9:00 A.M., New York City time, on the next business day after the previously scheduled Expiration Date. During any such extension, all Shares previously tendered and not properly withdrawn will remain subject to the Offer, subject to the rights of a tendering stockholder to withdraw such stockholder’s Shares. “Expiration Date” means 12:00 midnight, New York City time, at the end of Wednesday, June 20, 2007, unless and until Offeror has extended the period during which the Offer is open, subject to the terms and conditions of the Merger Agreement, in which event the term “Expiration Date” means the latest time and date at which the Offer, as so extended by Offeror, will expire.

Tenders of Shares made pursuant to the Offer are irrevocable, except that Shares tendered pursuant to the Offer may be withdrawn at any time on or prior to the Expiration Date, and, unless previously accepted for payment by Offeror pursuant to the Offer, may also be withdrawn at any time after July 21, 2007. For a withdrawal to be effective, a written or facsimile transmission notice of withdrawal must be timely received by the Depositary at one of its addresses set forth on the back cover of the Offer to Purchase. Any notice of withdrawal must specify the name of the person who tendered the Shares to be withdrawn, the number of Shares to be withdrawn and the name of the registered holder, if different from that of the person who tendered such Shares. All questions as to the form and validity (including time of receipt) of any notice of withdrawal will be determined by Offeror, in its sole discretion, whose determination will be final and binding. None of Offeror, Cardinal Health, any of their affiliates or assigns, the Depositary, the Information Agent or any other person will be under any duty to give notification of any defects or irregularities in any notice of withdrawal or incur any liability for failure to give such notification. Withdrawals of Shares may not be rescinded. Any Shares properly withdrawn will thereafter be deemed not to have been validly tendered for purposes of the Offer. However, withdrawn Shares may be re-tendered at any time prior to the Expiration Date by following one of the procedures described in Section 3 of the Offer to Purchase.

The information required to be disclosed by Rule 14d-6(d)(1) of the General Rules and Regulations under the U.S. Securities Exchange Act of 1934, as amended, is contained in the Offer to Purchase and is incorporated herein by reference.

VIASYS has provided Offeror with VIASYS’ stockholder list and security position listing for the purpose of disseminating the Offer to holders of Shares. The Offer to Purchase and the related Letter of Transmittal and, if required, other relevant materials will be mailed by Offeror to record holders of Shares and furnished to brokers, dealers, commercial banks, trust companies and similar persons whose names, or the names of whose nominees, appear on the stockholder list or, if applicable, who are listed as participants in a clearing agency’s security position listing, for subsequent transmittal to beneficial owners of Shares.

The Offer to Purchase and the related Letter of Transmittal contain important information which should be read carefully before any decision is made with respect to the Offer.

Any questions and requests for assistance may be directed to the Information Agent as set forth below. Requests for copies of the Offer to Purchase and the related Letter of Transmittal and all other tender offer materials may be directed to the Information Agent, and copies will be furnished promptly at Offeror’s expense. Offeror will not pay any fees or commissions to any broker or dealer or any other person (other than the Information Agent) for soliciting tenders of Shares pursuant to the Offer.
