DIVIDEND CAPITAL DIVERSIFIED PROPERTY FUND INC.

(Exact Name of Registrant as Specified in its Charter)

Registrant’s telephone number, including area code (303) 228-2200

Check the appropriate box below if the Form 8-K filing is intended to simultaneously satisfy the filing obligation of the registrant under any of the following provisions (see General Instruction A.2. below):

On April 7, 2014 (the “Effective Date”), Dividend Capital Diversified Property Fund Inc. (referred to herein as the “Company,” “we,” “our,” or “us”), entered into a Restricted Stock Unit Agreement (the “Agreement”) with its external advisor, Dividend Capital Total Advisors LLC (our “Advisor”). Pursuant to the terms of the Agreement, we have granted our Advisor 493,575 restricted stock units (“RSUs”), in return for offsets of future advisory fees and expenses as described further below. Each RSU will, upon vesting, entitle the Advisor to one Class I share of our common stock. The Advisor is expected to redistribute a significant portion of the RSUs and/or shares to senior level employees of the Advisor and its affiliates that provide services to us, although the terms of such redistributions (including the timing, amount and recipients) remain solely in the discretion of the Advisor. The purpose of the Agreement is intended to further promote an alignment of interests among our stockholders, the Advisor and the personnel of our Advisor and its affiliates, and is intended to promote retention of the personnel of our Advisor and its affiliates.

Vesting and Payment Offset

Except as otherwise described below, 25% of the RSUs will vest on each of April 15, 2014, April 15, 2015, April 15, 2016 and April 14, 2017, respectively (each a “Vesting Date”). On each Vesting Date, an offset amount (each, an “Offset Amount”) will be calculated and deducted on a pro rata basis over the next 12 months from the cash payments otherwise due and payable to the Advisor under our then-current advisory agreement (the “Advisory Agreement”) for any fees or expense reimbursements. Each Offset Amount will equal the number of RSUs vesting on such date multiplied by $6.96, which was the net asset value per Class I share publicly disclosed by us (the “Class I NAV”) as of the end of the Effective Date (the “Effective Date Class I NAV”). Each Offset Amount will always be calculated based on the Effective Date Class I NAV, even beyond the initial Vesting Date. At the end of each 12-month period following each Vesting Date, if the Offset Amount has not been fully realized by offsets from the cash payments otherwise due and payable to the Advisor under the Advisory Agreement, the Advisor shall promptly pay any shortfall to us.

Termination

The Agreement will automatically terminate upon termination or non-renewal of the Advisory Agreement, by any party for any reason. In addition, upon a change in control of us, then either the Advisor or we may immediately terminate the Agreement. Further, the Advisor may immediately terminate the Agreement if we exercise certain rights under the Agreement to replace the RSUs with another form of compensation.

Upon termination of the Agreement, the Advisor will promptly pay any unused Offset Amounts to us or, at the Advisor’s election, return Class I shares in equal value based on the Class I NAV as of the date of termination of the Agreement. In addition, upon termination of the Agreement, all unvested RSUs will be forfeited except that, unless the Agreement was terminated at the election of the Advisor following a change in control of us or as a result of a premature termination of the Advisory Agreement at our election for cause (as defined in the Advisory Agreement) or upon the bankruptcy of the Advisor, then following such forfeiture of RSUs, the Advisor will have the right to acquire from us the number of Class I shares equal to the number of RSUs forfeited, in return for a purchase price equal to such number of Class I shares multiplied by the Effective Date Class I NAV. The Advisor must notify us of its election to exercise the foregoing acquisition right within 30 days following the termination of the Agreement, and the parties will close the transaction within 60 days following the termination of the Agreement.

Dividend Equivalent Payments

If our board of directors declares and we pay a cash dividend on Class I shares for any period in which the RSUs are unpaid and outstanding (regardless of whether such RSUs are then vested), the Advisor will be entitled to dividend equivalents (“Dividend Equivalents”) with respect to that cash dividend equal to the cash dividends that would have been payable on the same number of Class I shares as the number of RSUs subject to the Agreement had such Class I shares been outstanding during the same portion of such period as the RSUs were unpaid and outstanding. Any such Dividend Equivalents may be paid in cash or Class I shares, at the Advisor’s election.
