FOURTH AMENDED AND RESTATED DIVIDEND REINVESTMENT PLAN Adopted August 11, 2015

KBS Real Estate Investment Trust III, Inc., a Maryland corporation (the “Company”), has adopted a Fourth Amended and Restated Dividend Reinvestment Plan (the “DRP”), the terms and conditions of which are set forth below. Capitalized terms shall have the same meaning as set forth in the Company’s charter unless otherwise defined herein.

1.Number of Shares Issuable. The number of shares of Common Stock authorized for issuance under the DRP is the lesser of 80,000,000 shares and $760,000,000 of shares of Common Stock.

2.Participants. “Participants” are holders of the Company’s shares of Common Stock who elect to participate in the DRP.

3.Dividend Reinvestment. Exclusive of dividends and other distributions that the Company’s board of directors designates as ineligible for reinvestment through this DRP, the Company will apply that portion (as designated by a Participant) of the dividends and other distributions (“Distributions”) declared and paid in respect of a Participant’s shares of Common Stock to the purchase of additional shares of Common Stock for such Participant. The Company will not pay selling commissions on shares of Common Stock purchased in the DRP.

4.Procedures for Participation. Qualifying stockholders may elect to become Participants or to increase participation in the DRP by completing and executing the Subscription Agreement, an enrollment form or any other Company-approved authorization form as may be available from the Company, the dealer manager or participating broker-dealers. Participation in the DRP will begin with the next Distribution payable after receipt of a Participant’s subscription agreement, enrollment form or other Company approved authorization form. Shares will be purchased under the DRP on the date that the Company makes a Distribution. Distributions will be paid upon the terms as authorized and declared by the Company’s board of directors.

5.Purchase of Shares. Until the Company establishes an estimated value per share of Common Stock for a purpose other than to set the price to acquire a share of Common Stock in the Company’s primary public offering, Participants will acquire Common Stock at a price per share equal to 95% of the price to acquire a share of Common Stock in the Company’s then-effective or most recently effective primary public offering (ignoring any discounts that may be available to certain categories of investors). Once the Company establishes an estimated value per share of Common Stock for a purpose other than to set the price to acquire a share in the Company’s primary public offering, Participants will acquire Common Stock at a price equal to 95% of the estimated value of the Company’s Common Stock, as estimated by the Company’s advisor or other firm chosen by the board of directors for that purpose. Participants in the DRP may purchase fractional shares so that 100% of the Distributions will be used to acquire shares. However, a Participant will not be able to acquire shares under the DRP to the extent such purchase would cause it to exceed limits set forth in the Company’s charter, as amended.

6.Taxation of Distributions. The reinvestment of Distributions in the DRP does not relieve Participants of any taxes that may be payable as a result of those Distributions and their reinvestment pursuant to the terms of this DRP.

7.Share Certificates. The shares issuable under the DRP shall be uncertificated until the board of directors determines otherwise.

8.Voting of DRP Shares. In connection with any matter requiring the vote of the Company’s stockholders, each Participant will be entitled to vote all shares acquired by the Participant through the DRP.

9.Reports. Within 90 days after the end of the calendar year, the Company shall provide each Participant with (i) an individualized report on the Participant’s investment, including the purchase date(s), purchase price and number of shares owned, as well as the amount of Distributions received during the prior year; and (ii) all material information regarding the DRP and the effect of reinvesting dividends, including the tax consequences thereof. The Company shall provide such information reasonably requested by the dealer manager or a participating broker-dealer, in order for the dealer manager or participating broker-dealer to meet its obligations to deliver written notification to Participants of the information required by Rule 10b-10(b) promulgated under the Securities Exchange Act of 1934.

10.Termination by Participant. A Participant may terminate participation in the DRP at any time by delivering to the Company a written notice. To be effective for any Distribution, such notice must be received by the Company at least four business days prior to the last business day of the month to which the Distribution relates. Notwithstanding the preceding sentence, if the Company publicly announces in a filing with the Securities and Exchange Commission a new offering price of its Common Stock under the DRP, then a Participant shall have no less than two business days after the date of such announcement to notify the Company in writing of Participant’s termination of participation in the DRP and Participant’s termination will be effective for the next date shares are purchased under the DRP. Any transfer of shares by a Participant will terminate participation in the DRP with respect to the transferred shares. Upon termination of DRP participation, Distributions will be distributed to the stockholder in cash.

11.Amendment or Termination of DRP by the Company. The Company may amend or terminate the DRP for any reason upon ten days’ notice to the Participants. The Company may provide notice by including such information (a) in a Current Report on Form 8-K or in its annual or quarterly reports, all publicly filed with the Securities and Exchange Commission or (b) in a separate mailing to Participants.

12.Liability of the Company. The Company shall not be liable for any act done in good faith, or for any good faith omission to act.

13.Governing Law. The DRP shall be governed by the laws of the State of Maryland.
