The terms of the dividend, including the ability of stockholders to elect to receive the distribution in the form of cash or shares of Sunstone’s common stock, and a limitation on the aggregate amount of cash to be paid in the distribution, were described in detail in the Notice of Dividend dated January 2, 2015, which was previously disseminated to stockholders. Election cards were required to be submitted prior to 5:00 p.m. (Eastern Time) on January 21, 2015.

Based on stockholder elections, the aggregate dividend will consist of approximately $37.0 million in cash and 2,135,464 shares of Sunstone’s common stock. The number of shares included in the distribution is calculated based on a stock price of $17.49 per share of Sunstone common stock, the average closing price per share of Sunstone’s common stock on the New York Stock Exchange on January 20 and 21, 2015. Summarized results of the dividend elections are as follows:

·      Sunstone will pay the dividend in shares of its common stock to all other stockholders.

·      Sunstone will pay fractional shares in cash.

The dividend (whether received in cash, stock, or a combination thereof) will be treated for Federal income tax purposes as an ordinary dividend attributable to and includable in 2014, allowing Sunstone to satisfy its 2014 real estate investment trust distribution requirements while preserving cash for other corporate purposes.
