of the Offer and the Merger, was 90 Swiss Francs per share) on either of (i) the
date of the execution of the purchase agreement for the JOMED Equity Offering
(the "Purchase Agreement") or (ii) on the first trading day
   2

immediately prior to the closing date of the Purchase Agreement, as such date is
defined in the Purchase Agreement. See Sections 11 and 15.

     Please furnish copies of the enclosed materials to those of your clients
for whose accounts you hold Shares registered in your name or in the name of
your nominee.

          2.  Letter of Transmittal for your use in accepting the Offer and
     tendering Shares and for the information of your clients (manually signed

     Shares);

          3.  Notice of Guaranteed Delivery to be used to accept the Offer if
     Share Certificates are not immediately available or if such certificates

     basis;

          4.  A printed form of letter that may be sent to your clients for
     whose accounts you hold Shares registered in your name or in the name of
     your nominee, with space provided for obtaining such clients' instructions
     with regard to the Offer;

          5.  The letter to stockholders of the Company from Reinhard J.
     Warnking, Chairman and Chief Executive Officer of the Company, accompanied
     by the Company's Solicitation/Recommendation Statement on Schedule 14D-9
     filed with the Securities and Exchange Commission by the Company, which
     includes the recommendation of the Board of Directors of the Company (the
     "Board of Directors") that stockholders accept the Offer and tender their
     Shares to the Purchaser pursuant to the Offer; and

          6. Guidelines of the Internal Revenue Service for Certification of
     Taxpayer Identification Number on Substitute Form W-9.

     The Company's Board of Directors, at a special meeting held on August 5,
2000, unanimously (1) determined that the Merger Agreement (as defined below)
and the transactions contemplated thereby, including the Offer and the Merger
(as defined below), are fair to and in the best interests of the Company's
stockholders; (2) approved and declared advisable the Merger Agreement and the
transactions contemplated thereby, including the Offer and the Merger; and (3)
recommended that the Company's stockholders accept the Offer and tender their
Shares thereunder.

     The Offer is being made pursuant to an Agreement and Plan of Merger, dated
as of August 5, 2000 (the "Merger Agreement"), among JOMED, the Purchaser and
the Company. The Merger Agreement provides for, among other things, the making
of the Offer by the Purchaser, and further provides that the Purchaser will be
merged with and into the Company (the "Merger") as soon as practicable following
the satisfaction or waiver of each of the conditions to the Merger set forth in
the Merger Agreement. Following the Merger, the Company will continue as the
surviving corporation, wholly owned by JOMED, and the separate corporate
existence of the Purchaser will cease.

     In order to take advantage of the Offer, (i) a duly executed and properly
completed Letter of Transmittal and any required signature guarantees, or an
Agent's Message (as defined in the Offer to Purchase) in connection with a
book-entry delivery of Shares, and other required documents should be sent to
the Depositary and (ii) Share Certificates representing the tendered Shares
should be delivered to the Depositary, or such Shares should be tendered by
book-entry transfer into the Depositary's account maintained at the Book-Entry
Transfer Facility (as described in the Offer to Purchase), all in accordance
with the instructions set forth in the Letter of Transmittal and the Offer to
Purchase.

     If holders of Shares wish to tender, but it is impracticable for them to
forward their Share Certificates or other required documents prior to the
Expiration Date or to comply with the book-entry transfer procedures on a timely
basis, a tender may be effected by following the guaranteed delivery procedures
specified in Section 3 of the Offer to Purchase.

                                        2

     The Purchaser will not pay any fees or commissions to any broker or dealer
or other person (other than the Depositary as described in the Offer to
Purchase) for soliciting tenders of Shares pursuant to the Offer. The Purchaser
will, however, upon request, reimburse you for customary mailing and handling
costs incurred by you in forwarding the enclosed materials to your customers.

     The Purchaser will pay or cause to be paid all stock transfer taxes
applicable to its purchase of Shares pursuant to the Offer, except as otherwise
provided in Instruction 6 of the Letter of Transmittal.
