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 24, 2006, June 8, 2005, and August 31, 2004,
respectively, the Registrant's shareholders approved the implementation of the
2006 Convertible Bond Program, 2005 Convertible Bond Program, and 2004
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 of the Registrant and its affiliated subsidiary
companies and, with the exception of the 2006 and the 2004 Convertible Bond
Program, consultants are eligible to acquire Shares when converting Convertible
Bonds, with a nominal value of (euro)1.00 per Convertible Bond. When converting
Convertible Bonds into Shares, holders are required to pay for each Share an
amount equal to 100% of the relevant conversion price minus EUR 1.

                  The Management Board, together with the Registrant's
supervisory board (Aufsichtsrat) (the "Supervisory Board"), and, to the extent
that the Registrant's Management Board is concerned, the Supervisory Board
alone, determines whether the Shares underlying the Convertible Bonds will be
made available from concurrently approved 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 2006 Convertible Bond
Program, 2005 Convertible Bond Program, and 2004 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% 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).

                  Under the 2006 Convertible Bond Program, 2005 Convertible Bond
Program, and 2004 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 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 2006 Convertible Bond
Program, 2005 Convertible Bond Program, and 2004 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. Convertible Bonds issued pursuant to the 2006

                                                                               6

<PAGE>


Convertible Bond Program, the 2005 Convertible Bond Program, and the 2004
Convertible Bond Program may not be exercised unless the price of the
Registrant's shares develops better than a reference index during the four weeks
prior to the date of exercise. For the 2006 Convertible Bond Program such
reference index is the TecDax index of the Frankfurt Stock Exchange and for the
2005 Convertible Bond Program and the 2004 Convertible Bond Program it is the
Prime IG Biotechnology Index of the Frankfurt Stock Exchange. Pursuant to the
2006 Convertible Bond Program, the 2005 Convertible Bond Program, and the 2004
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 statements (or, in the case of the 2006 Convertible Bond
Program, six weeks after the second day after such publication), 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. 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. In addition, the Convertible Bonds 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

Item 8.           Exhibits.

                  See attached 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 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.


                                                                               8

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 24, 2006, June 8, 2005, and August 31, 2004,
respectively, the Registrant's shareholders approved the implementation of the
2006 Convertible Bond Program, 2005 Convertible Bond Program, and 2004
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 of the Registrant and its affiliated subsidiary
companies and, with the exception of the 2006 and the 2004 Convertible Bond
Program, consultants are eligible to acquire Shares when converting Convertible
Bonds, with a nominal value of (euro)1.00 per Convertible Bond. When converting
Convertible Bonds into Shares, holders are required to pay for each Share an
amount equal to 100% of the relevant conversion price minus EUR 1.

                  The Management Board, together with the Registrant's
supervisory board (Aufsichtsrat) (the "Supervisory Board"), and, to the extent
that the Registrant's Management Board is concerned, the Supervisory Board
alone, determines whether the Shares underlying the Convertible Bonds will be
made available from concurrently approved 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 2006 Convertible Bond
Program, 2005 Convertible Bond Program, and 2004 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% 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).

                  Under the 2006 Convertible Bond Program, 2005 Convertible Bond
Program, and 2004 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 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 2006 Convertible Bond
Program, 2005 Convertible Bond Program, and 2004 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. Convertible Bonds issued pursuant to the 2006

                                                                               6
Convertible Bond Program, the 2005 Convertible Bond Program, and the 2004
Convertible Bond Program may not be exercised unless the price of the
Registrant's shares develops better than a reference index during the four weeks
prior to the date of exercise. For the 2006 Convertible Bond Program such
reference index is the TecDax index of the Frankfurt Stock Exchange and for the
2005 Convertible Bond Program and the 2004 Convertible Bond Program it is the
Prime IG Biotechnology Index of the Frankfurt Stock Exchange. Pursuant to the
2006 Convertible Bond Program, the 2005 Convertible Bond Program, and the 2004
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 statements (or, in the case of the 2006 Convertible Bond
Program, six weeks after the second day after such publication), 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. 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. In addition, the Convertible Bonds 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.

                  The Registrant provides customary liability insurance for its
directors and officers. The Registrant's Articles of Association do not provide
for any indemnification of members of the Registrant's Supervisory Board and the
Registrant's Management Board for any liabilities they may incur.

Item 7.           Exemption from Registration Claimed.

                  Not applicable.

                                                                               7
Item 8.           Exhibits.

                  See attached 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 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.

                                                                               8
