Item 4.   Description of Securities.

     I.   Shares

          The Shares are registered pursuant to Section 12(b) of the Exchange
Act, and, therefore, the description with respect thereto is omitted.

     II.  Convertible Bonds

          On May 21, 2003, and on June 11, 2002, respectively, the Registrant's
shareholders approved the implementation of the 2003 Convertible Bond Program
and the 2002 Convertible Bond Program. Under these programs, members of the
Registrant's management board (Vorstand) (the "Management Board"), members of
the management bodies and other employees with management functions of the
Registrant's affiliates and consultants are eligible to acquire the Registrant's
Shares pursuant to convertible bonds, with a nominal value (euro) 1.00 per
convertible bond ("Convertible Bonds"). The May 21, 2003 annual general meeting
of the Registrant approved the creation of conditional capitals in the amount of
up to (euro) 200,000, to cover the Convertible Bonds to be issued pursuant to
the 2003 Convertible Bond Program, and the June 11, 2002 annual general meeting
of the Registrant approved the creation of a conditional capital in the amount
of up to (euro) 500,000 to cover the Convertible Bonds to be issued pursuant to
the 2002 Convertible Bond Program, in each case subject to adjustment upon
changes to the Registrant's capitalization. The Management Board, together with
the Registrant's supervisory board (Aufsichtsrat) (the "Supervisory Board"),
and, to the extent that the Management Board is concerned, the Supervisory Board
alone, determines whether the Shares underlying the Convertible Bonds will be
made available from these conditional capitals or from a program to repurchase
the Registrant's Shares.

          The Management Board, and to the extent that the Management Board is
concerned, the Supervisory Board, selects the eligible persons to whom
Convertible Bonds will be offered and determines the amounts, vesting periods
and other relevant terms (including acceleration provisions) of the Convertible
Bonds.

          Convertible Bonds issued pursuant to the 2003 Convertible Bond Program
and the 2002 Convertible Bond Program may be exercised by the bondholder, after
expiry of the two-year waiting period from the date of issuance, to obtain one
Share for each Convertible Bond upon payment of the conversion price and bear
interest at 3.5 percent per annum starting from the date of issuance. The
Convertible Bonds may be offered to the eligible persons for subscription within
the last 15 working days of each calendar month. The time to maturity of the
Convertible Bonds is ten years from the date of issuance, after which the
Convertible Bonds lapse without compensation to the bondholder (other than
repayment of the nominal amount of the Convertible Bond plus accrued interest).
Convertible Bonds are generally not transferable during the life of the
bondholder, except to a credit institution specified by the Registrant following
the expiration of the two-year waiting period or of the cancellation period
described below.

          Under the 2003 Convertible Bond Program and the 2002 Convertible Bond
Program, Shares issued upon exercise of a Convertible Bond --provided that they
are issued before the beginning of the Registrant's annual general meeting that
resolves on the allocation of retained earnings --are entitled to dividends from
the beginning of the previous fiscal year. In

                                       6



the event that the Shares are issued after the Registrant's general meeting,
such Shares are entitled to dividends in the fiscal year in which they were
issued.

          Convertible Bonds issued under the 2003 Convertible Bond Program and
the 2002 Convertible Bond Program generally vest and become uncancellable in
one-quarter installments on each of the first four anniversaries of the date of
issuance. A Convertible Bond may not be exercised until the occurrence of each
of the following events: (i) satisfaction of a two-year waiting requirement
(measured from the date of issuance); (ii) vesting; and (iii) the achievement of
a share price performance goal on the date of exercise. With respect to
Convertible Bonds issued pursuant to the 2003 Convertible Bond Program, the
price of the Registrant's Shares on the Frankfurt Stock Exchange on the date of
exercise must exceed the share price on May 21, 2003 by 100 percent. With
respect to Convertible Bonds issued pursuant to the 2002 Convertible Bond
Program, the price of the Registrant's Shares on the Frankfurt Stock Exchange
must exceed the exercise price of the Convertible Bonds on five successive
trading days within one month prior to exercise by a certain percentage (which
percentage is ten percent for the first year after the expiration of the
two-year waiting period and is increased by five percent for each year
thereafter). In addition, pursuant to the 2003 Convertible Bond Program and the
2002 Convertible Bond Program, a Convertible Bond may only be exercised within a
period of six weeks after publication of the Registrant's quarterly reports or
annual financial statement, and may not be exercised during a subscription
rights offering by the Registrant and during the period from December 24 to
December 31 of each calendar year. Notwithstanding the foregoing, Convertible
Bonds may not be exercised following the expiration of their respective terms,
which under the plans cannot exceed ten years from the date of grant. The
Convertible Bonds are generally not transferable during the life of the
bondholder, but are inheritable upon the death of the bondholder.

          In the event of the termination of service of a bondholder, the
unvested portion of a Convertible Bond may be cancelled without compensation
(other than repayment of the nominal amount of the Convertible Bond plus accrued
interest), and the vested portion is generally cancelled 12 months after the
termination of service. In addition, the Registrant has the right to cancel a
bondholder's Convertible Bonds in the event insolvency proceedings are
instituted against the assets of such bondholder or the Convertible Bonds are
attached by a creditor of such bondholder for more than six months. A bondholder
may cancel his or her Convertible Bonds with three months' notice at the end of
a quarter.

          In the event of the Registrant's merger with and into another company,
the Registrant's reorganization, a change in the nominal value of the Shares or
similar changes to the Registrant's capitalization or corporate structure, the
Convertible Bonds will be replaced by the right to purchase, at the base price,
an equivalent number, respectively, of Shares, equity interests or other
interests in the Registrant or the successor corporation, the value of which
corresponds to the market value of the Shares on the date on which such event
occurred.

Item 5.   Interests of Named Experts and Counsel.

          Not applicable.

Item 6.   Indemnification of Directors and Officers.

                                       7



          We provide customary liability insurance for our directors and
officers. Our Articles of Association do not provide for any indemnification of
members of our Supervisory Board and our Management Board for any liabilities
they may incur.


Item 7.   Exemption from Registration Claimed.

          Not applicable.

Item 8.   Exhibits.

          See Exhibit Index.

Item 9.   Undertakings.

          (a)  The undersigned Registrant hereby undertakes:

               (1)  To file, during any period in which offers or sales are
          being made of securities registered hereby, a post-effective amendment
          to this Registration Statement to include any material information
          with respect to the plan of distribution not previously disclosed in
          the Registration Statement or any material change to such information
          in the Registration Statement;

               (2)  That, for the purpose of determining any liability under
          the Securities Act, each such post-effective amendment shall be deemed
          to be a new registration statement relating to the securities offered
          therein, and the offering of such securities at that time shall be
          deemed to be the initial bona fide offering thereof; and

               (3)  To remove from registration by means of a post-effective
          amendment any of the securities being registered which remain unsold
          at the termination of the offering.

          (b)  The undersigned Registrant hereby further undertakes that, for
purposes of determining any liability under the Securities Act, each filing of
the Registrant's annual report pursuant to Section 13(a) or 15(d) of the
Exchange Act that is incorporated by reference in the Registration Statement
shall be deemed to be a new registration statement relating to the securities
offered therein, and the offering of such securities at that time shall be
deemed to be the initial bona fide offering thereof.

          (c)  Insofar as indemnification for liabilities arising under the
Securities Act may be permitted to directors, officers and controlling persons
of the Registrant pursuant to the foregoing provisions, or otherwise, the
Registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
Securities Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of

                                       8



appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Securities Act and will be governed by
the final adjudication of such issue.

                                       9



                                    Part III



                                   SIGNATURES

          Pursuant to the requirements of the Securities Act, the Registrant
certifies that it has reasonable grounds to believe that it meets all of the
requirements for filing on Form S-8 and has duly caused this Registration
Statement to be signed on its behalf by the undersigned, thereunto duly
authorized, in Munich, Germany on July 2, 2004.
