CUSIP No. 251591103 SCHEDULE 13D/A

This Amendment No. 9 (“Amendment No. 9”) amends and supplements the statement on Schedule 13D initially filed on May 15, 2009 (the “Original Filing”), as amended by Amendment No. 1 filed on August 20, 2009, Amendment No. 2 filed on September 14, 2009, Amendment No. 3 filed on September 18, 2009, Amendment No. 4 filed on February 16, 2010, Amendment No. 5 filed on March 21, 2011, Amendment No. 6 filed on April 26, 2011, Amendment No. 7 filed on March 30, 2012, and Amendment No. 8 filed on October 5, 2012. Information reported in the Original Filing, as amended, remains in effect except to the extent that it is amended, restated or superseded by information contained in this Amendment No. 9. Capitalized terms used and not defined in this Amendment No. 9 have the meanings set forth in the Original Filing, as amended.

Item 2. Identity and Background

Item 4 is hereby incorporated by reference.

Item 4. Purpose of the Transaction

On November 12, 2012, the Joinder Agreement, as defined in the Original Filing, was amended to terminate the obligations of Dr. Michael Otto (“Dr. Otto”) and Janina Otto under the Joinder Agreement. This amendment was effectuated by the execution of the Termination Agreement, dated November 12, 2012, by and among Mr. Otto, Katharina Otto-Bernstein, Dr. Otto, Janina Otto and KG CURA Vermögensverwaltung G.m.b.H. & Co. (“KG CURA”). Consequently, Dr. Otto and Janina Otto are no longer parties to the Investors’ Rights Agreement, as defined in the Original Filing. Additionally, Dr. Otto and Janina Otto do not have any agreement or understanding with other persons to acquire, hold, vote or dispose of Common Shares. Mr. Otto and Katharina Otto-Bernstein are still parties to the Joinder Agreement and the Investors’ Rights Agreement. For the purposes of determining Mr. Otto’s right to nominate two directors to the Issuer’s board of directors, the Investors’ Rights Agreement continues to aggregate the collective shares beneficially owned by the descendants of Professor Werner Otto, which includes those owned by Dr. Otto and Janina Otto.

A copy of the Termination Agreement is filed herewith as an exhibit and incorporated herein by reference.

Item 5. Interest in Securities of the Issuer.

Item 5 is hereby amended to add the following:

(a) Mr. Otto and Katharina Otto-Bernstein may be deemed to beneficially own, in the aggregate, 55,429,990 Common Shares, representing 17.9% of the Issuer’s outstanding Common Shares (based on 309,765,482 shares reported to be outstanding as of November 1, 2012 by the Issuer on its Form 10-Q filed on November 9, 2012).

CUSIP No. 251591103 SCHEDULE 13D/A

(b) With respect to any rights or powers to vote, or to direct the vote of, or to dispose of, or direct the disposition of, the Common Shares referenced in paragraph 5(a), Mr. Otto has sole voting power and sole dispositive power with regard to 39,674,485 Common Shares. Katharina Otto-Bernstein has sole voting power and sole dispositive power with regard to 15,755,505 Common Shares. Dr. Otto has sole voting power and sole dispositive power with regard to 2,375,916 Common Shares owned by him, and shared voting power and shared dispositive power with regard to 594,965 Common Shares owned by his daughter Janina Otto pursuant to a power of attorney. Janina Otto has shared voting power and shared dispositive power with regard to 594,965 Common Shares.

(c) The Reporting Persons have not effected any transactions in the Common Shares since the most recent filing on Schedule 13D on October 5, 2012.

(e) On November 12, 2012, upon the execution of the Termination Agreement, Dr. Otto and Janina Otto each ceased to be part of the group formed by the Reporting Persons.

Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer.
