Item 1.01 Entry into a Material Definitive Agreement.

As previously disclosed on March 10, 2014, DDR Corp. (“DDR”) signed a letter of intent to sell its 50% ownership interest in Sonae Sierra Brazil B.V., S.à r.l. (“SSB”), a company having its corporate seat at Amsterdam, the Netherlands, to Alexander Otto and his affiliates. On April 28, 2014, affiliates of DDR (the “Sellers”) entered into a Share Purchase Agreement (the “Agreement”) with Mr. Otto and certain of his affiliates (the “Purchasers”). Pursuant to the Agreement, the Sellers agreed to sell their 50% ownership interest in SSB to the Purchasers for approximately $343.6 million, which interest represents DDR’s entire investment in Brazil. SSB’s primary assets include an approximately 66% indirect ownership interest in Sonae Sierra Brasil, S.A., a publicly traded company in Brazil, and an indirect interest in the Parque Dom Pedro shopping center. The Agreement contains terms and conditions that are customary for transactions of this type. The sale transaction contemplated in the Agreement was consummated on April 28, 2014.

DDR and Mr. Otto are parties to an Investor Rights Agreement, dated May 11, 2009 (the “Investor Rights Agreement”), pursuant to which Mr. Otto has a right to nominate up to two individuals for election to DDR’s Board of Directors depending on his family’s level of ownership of DDR. In accordance with the Investor Rights Agreement, Dr. Volker Kraft and Dr. Thomas Finne have been proposed by Mr. Otto and subsequently nominated and elected to DDR’s Board of Directors annually since 2009. Furthermore, Dr. Finne is a Managing Director of the entities affiliated with Mr. Otto that agreed to purchase a portion of the Company’s ownership interest in SSB.
