Retirement (ln)security* Amid an uncerta in political and economic climate, planning for ret irement is a challenge for individuals across mult iple generations. Many are legitimately concerned that they will outlive their savings as Social Security benefits may be discontinued and healthcare costs continue to rise.1 justified Concerns The U.S. population is growing older and living longer, and will li kely face increased expenses with fewer traditional sources of fixed income.

Investment Mix One of the most widely referenced financial rules of thumb asserts that to successfully fund a 30-year retirement, individuals should adhere to an annual withdrawal rate of four percent.1 Achieving a stable 4% return rate with traditional investments today is more difficult than in past periods. Traditional income-oriented investments like treasuries and COs are historically low and offer a limited income stream. Equities are near all-time highs but susceptible to market fluctuations. Treasury yields are near historic lows.2 U.S. Government 10-Year Treasury Yields (12/30/94- 12/31/18) 1% -- 0% -- 1994 1996 1998 2000 2002 2004 2006 Savings instruments are near all-time lows.2 Bloomberg CD 12-Month Rate (11/29/96- 12/31/18) 8% 7% 6% 5% 0%-- 1996 1998 2000 2002 2004 2006 2008 2008 2010 2010 2012 2014 2016 2018 2012 2014 2016 2018 1) CNN Money, Three Things You Need To Know About the 4% Rule, February 2018. 2) Bloomberg.

What Is Preferred Stock? Preferred stock is a class of ownership in a corporation that generally has a higher priority claim on the company's assets and/or earnings than does common stock. It is often considered a fixed income alternative because it typically pays a fixed dividend to shareholders. Preferred Stock May Provide: Greater Capital Preservation than Common Stock1 » Strategy aims to conserve and return the value of shareholders' capital » Common stock provides a buffer for possible impairments to the value of preferred stock » Unit price of preferred stock does not fluctuate with market movements Current lncome2 » Dividend payments are typically paid quarterly Dividend Priority » Generally preferred shareholders are entitled to receive dividends before common shareholders and have priority rights with regard to payments in the event of a liquidation of the company CMCT CIM Commercial Trust (NASDAQ: CMCT) is operated by CIM Group,® a community-focused real estate and infrastructure owner, operator and lender.

Attractive Capital Structure We believe an appropriately balanced capital structure helps to preserve the preferred shareholders' position. Prudent, lower levels of debt can support a company's efforts to cover preferred dividends, which are distributed after debt payments have been made. Common equity can help protect preferred shareholders by acting as a "loss cushion." If a company's value decreases, common equity must be depleted before the value of preferred stock is impaired. How CMCT Preferred Equity Stacks Up The way companies are capitalized may impact the risk associated with owning preferred stock. We believe CMCT has an attractive capital structure, that supports the preservation of principal value and the availability of funds to provide stable income for preferred shareholders. Capital Stack1 (common stock as% of capitalization) 3% Preferred Stock When making payments. the company prioritizes preferred shareholders after debt obligations. 61% Common Stock Average listed REIT t 45% Common Stock CMCT Target2 Principal "Loss Cushion" 26% Common Stock If a loss in company value occurs. common stock will be affected first Average of the 10% of REITs with the most indebtedness 1) As a percentage of total capitalization. CMCT target is based on preferred stock and debt as a percentage of the fair value of assets. The "Median Listed REIT" and the "Average of the 1 Oo/o of REITs with the most indebtedness" charts are constructed using publicly available information of all companies in the SNL US Equity REIT index (the "Index") as of September 30, 2018. The companies in the Index are not all office REITs and therefore comparing their capital structure to that of CMCTs target structure may not be appropriate. Not all the companies in the Index contain preferred stock in their capital structure. 2) As of March 31, 2019, the capital structure of CMCT was: 32% debt and preferred stock (including Series A Preferred Stock and Series L Preferred Stock) and 68% common stock.
