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reported in the Original Filing, as amended, remains in effect except to the extent that it is amended, restated or superseded by information contained in this Amendment No. 9.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.

Item 4 is hereby incorporated by reference.

Capitalized Terms not defined herein shall have the meanings ascribed to them in the Joinder Agreement.

RECITALS

WHEREAS, the Parties entered into the Joinder Agreement; and

WHEREAS, the Parties now wish to remove Dr. Michael Otto and Ms. Janina Otto (the “Terminating Parties”) as parties to the Joinder Agreement;

NOW, THEREFORE, the Parties agree as follows:

1. Agreement To Be Bound. The Parties hereby agree that upon execution of this Termination Agreement, Mr. Alexander Otto and Ms. Katharina Otto-Bernstein will continue to be bound by, and subject to, all of the covenants, terms and conditions of the Joinder Agreement, the Stock Purchase Agreement, dated as of February 23, 2009 by and between DDR Corp. (f/k/a Developers Diversified Realty Corporation) (“DDR”) and Mr. Alexander Otto (the “Stock Purchase Agreement”), and each of the Ancillary Agreements, as applicable.

2. Removal of Certain Parties. The Parties hereby agree that upon execution of this Termination Agreement, the Terminating Parties will no longer be bound by, and subject to, any of the covenants, terms and conditions of the Joinder Agreement, the Stock Purchase Agreement, or any Ancillary Agreement; provided, however, that such termination shall not relieve any Party from liability for any breach of the Joinder Agreement prior to the effective time of this Termination Agreement.

3. Representative. The Parties agree and acknowledge that KG CURA shall act as their agent and is entitled to act on their behalf with regard to any matters relating to the Stock Purchase Agreement, the Joinder Agreement, this Termination Agreement and the Ancillary Agreements, which shall include the power (i) to give and receive notices and communications on behalf of the Terminating Parties, (ii) to waive provisions of the Stock Purchase Agreement, the Joinder Agreement and the Ancillary Agreements, (iii) to take all actions necessary or appropriate in the judgment of KG CURA for the accomplishment of the foregoing and to otherwise act on behalf of the Terminating Parties with respect to the Stock Purchase Agreement, the Joinder Agreement, this Termination Agreement and the Ancillary Agreements. A decision, act, consent or instruction of KG CURA shall constitute a decision of the Terminating Parties and shall be final, binding and conclusive upon each such Terminating Party, and DDR may rely upon any decision, act, consent or instruction of KG CURA as being the decision, act, consent or instruction of each and every such Terminating Party. KG CURA shall not be liable to the Terminating Parties for any act done or omitted while acting in good faith and in the exercise of reasonable judgment, and any act done or omitted pursuant to the written advice of counsel shall be conclusive evidence of such good faith.

4. Governing Law. Regardless of any conflict of law or choice of law principles that might otherwise apply, the Parties agree that this Termination Agreement shall be governed by and construed in all respects in accordance with the laws of the State of New York. The Parties agree and acknowledge that the State of New York has a reasonable relationship to the Parties and/or this Termination Agreement. As to any dispute or litigation arising out of or relating in any way to this Termination Agreement or the transactions at issue in the Stock Purchase Agreement, Joinder Agreement and Ancillary Agreements, the Parties agree and consent to be subject to the jurisdiction of the United States District Court for the Southern District of New York. If jurisdiction is not present in federal court, then the Parties agree and consent to the jurisdiction of the state courts of New York County, New York. Each Party irrevocably waives, to the fullest extent permitted by law, (a) any objection that it may now or hereafter have to laying venue of any litigation brought in such court, (b) any claim that any litigation brought in such court has been brought in an inconvenient forum, and (c) any defense that it may now or hereafter have based on lack of personal jurisdiction in such forum.

5. Counterparts. This Termination Agreement may be executed in several counterparts, each of which shall be deemed an original and all of which shall constitute one and the same instrument, and shall become effective when counterparts have been signed by each of the parties and delivered to the other parties; it being understood that all parties need not sign the same counterpart.

6. Descriptive Headings. The descriptive headings of this Termination Agreement are inserted for convenience only and do not constitute a part of this Termination Agreement.

7. Entire Agreement. This Termination Agreement constitutes the entire agreement among the Parties and supersedes all other prior agreements and understandings, both written and oral, between the parties with respect to the subject matter hereof.

8. Third-Party Beneficiary. The Parties acknowledge and agree that DDR shall be deemed a beneficiary of this Termination Agreement, and shall be entitled to enforce it as a third-party beneficiary of this Termination Agreement.
