Pursuant to the merger agreement, dated as of April 10, 2016, among Annaly, Hatteras and Ridgeback Merger Sub Corporation, a wholly owned subsidiary of Annaly (“Merger Sub”), Annaly intends to complete the acquisition of Hatteras through a second-step merger of Hatteras with and into Merger Sub without a vote of Hatteras’ stockholders, pursuant to Section 3-106.1 of the Maryland General Corporation Law (the “Merger”). In accordance with Maryland law, the Merger is expected to be consummated on July 12, 2016. Upon consummation of the Merger, Hatteras will become a wholly owned subsidiary of Annaly. In connection with the Merger, all shares of Hatteras common stock not validly tendered into the exchange offer will be cancelled and converted into the right to receive merger consideration in the same amounts offered in the exchange offer. Holders of these shares will have the opportunity to elect among the mixed consideration, the all-cash consideration and the all-stock consideration, subject to proration, as described in the prospectus/offer to exchange, dated July 8, 2016, filed by Annaly with the Securities and Exchange Commission in connection with the transaction. In addition, upon consummation of the Merger, all of the outstanding shares of Hatteras 7.625% Series A Cumulative Redeemable Preferred Stock (the “Hatteras Series A Preferred Stock”) will be cancelled and converted into the right to receive one newly issued share of Annaly’s 7.625% Series E Cumulative Redeemable Preferred Stock, which will have substantially the same terms as the existing terms of the Hatteras Series A Preferred Stock.

As a result of the acquisition, shares of Hatteras common stock and Hatteras Series A Preferred Stock will cease to be traded on the NYSE.
