W W W . K B S . C O M The information contained herein should be read in conjunction with, and is qualified by, the information in KBS Real Estate Investment Trust II’s (the “Company” or “KBS REIT II”) Annual Report on Form 10-K for the year ended December 31, 2020 (the “Annual Report”), and in the Company’s Quarterly Report on Form 10-Q for the period ended June 30, 2021 (the “Quarterly Report”), including the “Risk Factors” contained therein. Certain statements contained herein may be deemed to be forward-looking statements within the meaning of the Federal Private Securities Litigation Reform Act of 1995. The Company intends that such forward-looking statements be subject to the safe harbors created by Section 21E of the Securities Exchange Act of 1934, as amended. These statements include statements regarding the intent, belief or current expectations of the Company and members of its management team, as well as the assumptions on which such statements are based, and generally are identified by the use of words such as “may,” “will,” “seeks,” “anticipates,” “believes,” “estimates,” “expects,” “plans,” “intends,” “should” or similar expressions. Readers are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date they are made. The Company undertakes no obligation to update or revise forward-looking statements to reflect changed assumptions, the occurrence of unanticipated events or changes to future operating results over time, unless required by law. Such statements are subject to known and unknown risks and uncertainties which could cause actual results to differ materially from those contemplated by such forward-looking statements. The Company makes no representation or warranty (express or implied) about the accuracy of any such forward-looking statements. These statements are based on a number of assumptions involving the judgment of management. You should interpret many of the risks identified in this presentation and in our Annual Report and Quarterly Report as being heightened as a result of the ongoing and numerous adverse impacts of the COVID-19 pandemic. On March 5, 2020, KBS REIT II’s stockholders approved the sale of all of KBS REIT II’s assets and its dissolution pursuant to the terms of KBS REIT II’s plan of complete liquidation and dissolution (the “Plan of Liquidation”). There are many factors that may affect the amount of liquidating distributions ultimately paid to KBS REIT II’s stockholders, including the ultimate sale price of each asset and the actual liquidation timing, changes in market demand for office properties, the amount of taxes, fees and expenses relating to the liquidation, and unanticipated or contingent liabilities that could arise. No assurance can be given as to the amount or timing of liquidating distributions. Forward-Looking Statements 2 Important Disclosures

W W W . K B S . C O M The COVID-19 pandemic, together with the resulting measures imposed to help control the spread of the virus, has had a negative impact on the economy and business activity globally. The COVID-19 pandemic is negatively impacting almost every industry, including the U.S. office real estate industry and the industries of KBS REIT II’s tenants, directly or indirectly. The extent to which the COVID-19 pandemic impacts the Company’s operations and those of its tenants and the Company’s implementation of the Plan of Liquidation, depends on future developments, which are highly uncertain and cannot be predicted with confidence, including the scope, severity and duration of the pandemic, the actions taken to contain the pandemic or mitigate its impact, and the direct and indirect economic effects of the pandemic and containment measures, among others. Given the uncertainty and current business disruptions as a result of the outbreak of COVID-19, the Company’s implementation of the Plan of Liquidation may be materially and adversely impacted. Actual events may cause the value and returns on the Company’s investments to be less than that used for purposes of the Company’s estimated range of liquidating distributions as of March 11, 2021 and estimated net assets in liquidation as of June 30, 2021. For a full description of the methodologies, limitations and assumptions used in the calculation of the estimated liquidation value of the Company’s assets and liabilities, see the Company’s Annual Report and Quarterly Report. As with any valuation methodology, the methodologies used are based upon a number of estimates and assumptions that may not be accurate or complete. Moreover, the Company did not obtain appraisals in connection with the valuations. Even small changes to these assumptions could result in significant differences in the estimated range of liquidating distributions as of March 11, 2021. The statements herein also depend on factors such as: future economic, competitive and market conditions; the Company’s ability to maintain and/or improve occupancy levels and rental rates at its real estate properties; the Company’s ability to sell its real estate properties at the times and at the prices it expects; the Company’s ability to successfully negotiate modifications, extensions or any needed refinancing of its debt obligations; the Company’s ability to successfully implement the Plan of Liquidation; and other risks identified in the Annual Report and the Quarterly Report.

W W W . K B S . C O M Since April 1, 2020, a number of tenants have requested rent relief, most in the form of rent deferrals or abatement. Depending upon the duration of the pandemic, the various measures imposed to help control the spread of the virus and the corresponding economic slowdown, these tenants or additional tenants may seek rent deferrals or abatements in future periods or become unable to pay their rent. Through August 18, 2021, rent collections are as follows: Over the course of the COVID-19 crisis, the Company has received short-term rent relief requests from tenants who have been directly impacted by the COVID-19 pandemic. As of June 30, 2021, the Company had granted a total of $0.4 million in rent relief to eight tenants structured as temporary deferral arrangements of base rent or rent abatement. In most cases, it is in the Company’s best interest to help its tenants remain in business and reopen when restrictions are lifted. Current collections and rent relief requests to date may not be indicative of collections or requests in any future period. 5 Period of Rent Collected % of Rent Collected Q2 2020 98% Q3 2020 99% Q4 2020 99% Q1 2021 99% Q2 2021 99% July 2021 99% COVID-19: Rent Collections
