Developments Relating to Our Fourth Quarter Redemptions

Under the Class E share redemption program (the “Class E SRP”) of Dividend Capital Diversified Property Fund, Inc. (the “Company,” “we,” “our” or “us”) that is currently in effect, funds for redemptions made at the end of each quarter are generally limited to an amount equal to (i) funds received from the sale of Class E shares under our distribution reinvestment plan during such calendar quarter, plus (ii) 50% of the difference between (a) the proceeds (net of sales commissions) received by us from the sale of Class A, Class W and Class I shares in our public primary offering and under our distribution reinvestment plan during the most recently completed calendar quarter, and (b) the dollar amount used to redeem Class A, Class W and Class I shares during the most recently completed calendar quarter pursuant to the Class A, W and I share redemption program, less (iii) funds used for redemptions of Class E shares in the most recently completed quarter in excess of such quarter’s applicable redemption cap due to qualifying death or disability requests of stockholders during such calendar quarter. However, our board of directors may from time to time, but is not obligated to, authorize funds for redemptions of Class E shares in greater or lower amounts. The foregoing limitation is referred to as the “Quarterly Redemption Cap.” Notwithstanding the Class E liquidity level desired by our board of directors, pursuant to the Class E SRP, we will not redeem during any consecutive 12-month period more than five percent of the number of Class E shares of common stock outstanding at the beginning of such 12-month period (excluding certain redemptions made in connection with a stockholder’s death or disability) (referred to herein as the “Aggregate Redemption Cap”).

We expect the number of Class E shares to be redeemed in the fourth quarter of 2014 to be limited to the Aggregate Redemption Cap. Under the Aggregate Redemption Cap, we expect to redeem approximately $9.7 million (the “Fourth Quarter Redemption Cap”). In addition, we expect to redeem 100% of the qualifying redemption requests made in connection with a stockholder’s death or disability. Through December 16, 2014 (the “Deadline”), the last day for fourth quarter 2014 redemption requests to be submitted under the Class E SRP, we had received requests to redeem approximately 18.8 million shares of common stock (the “Total Fourth Quarter Redemption Requests”), approximately 571,000 of which are for qualifying death and disability redemption requests. Based on application of the Fourth Quarter Redemption Cap, we expect that requesting stockholders whose requests were received on or before the Deadline will be redeemed pro rata.

Based on the December 23, 2014 NAV of $7.16 per Class E share, we expect to redeem, for the fourth quarter of 2014, approximately 10% of the Class E shares requested to be redeemed on or before the Deadline, including all shares requested pursuant to qualifying death and disability requests. We expect that Class E shares requested to be redeemed on or before the Deadline pursuant to requests other than qualifying death and disability requests will be satisfied on a pro rata basis and that approximately 7% of such shares (the “Pro Rata Percentage”) will be redeemed. The actual Pro Rata Percentage of redemptions will be determined, in part, based on the NAV per share on December 31, 2014 pursuant to the terms of the Class E SRP. A copy of the Class E SRP was mailed to stockholders, was included as an exhibit to our Current Report on Form 8-K filed with the Securities and Exchange Commission on July 12, 2012, and is also available on our web site at www.dividendcapitaldiversified.com. In accordance with the Class E SRP, any portion of a redemption request of a stockholder that is not honored will be deemed automatically withdrawn, and any such stockholder may resubmit a request in a subsequent quarter (subject to the applicable Quarterly Redemption Cap and all other terms and conditions of the Class E SRP). We will not retain redemption requests that are not honored.

The Fourth Quarter Redemption Cap, Total Fourth Quarter Redemption Requests and Pro Rata Percentage are preliminary figures that are subject to change. Pursuant to the terms of the Class E SRP, stockholders who submitted timely redemption requests may withdraw their requests, in whole or in part, by submitting a written request that we receive on or before December 31, 2014. In addition, any stockholder who has requested redemption and is a participant in our distribution reinvestment plan will remain a participant in the distribution reinvestment plan unless we receive written notice terminating the stockholder’s participation in accordance with the distribution reinvestment plan. Any stockholder that wishes to withdraw a redemption request or terminate their participation in the distribution reinvestment plan should submit the same in writing to:

Forward-Looking Statements

This current report includes “forward-looking statements” regarding redemptions under the Company’s Class E SRP. These statements are based on certain assumptions and analyses made by the Company in light of the Company’s experience and the Company’s perception of current conditions, expected future developments and other factors the Company believes are appropriate. Such statements are subject to a number of assumptions, risks and uncertainties. Readers are cautioned not to place undue reliance on these forward-looking statements. Among the factors that may cause the Fourth Quarter Redemption Cap, Total Fourth Quarter Redemption Requests and Pro Rata Percentage to vary are future sales and redemptions of the Company’s shares of common stock and whether the Company’s board of directors authorizes funds for redemptions of Class E shares in greater or lower amounts than the standard Quarterly Redemption Cap. Except as required by applicable securities laws, the Company undertakes no obligation to publicly update or revise any forward-looking statements, whether as a result of future events, new information or otherwise.
