INVESTOR PRESENTATION 06. 2017 1 UPDATED 6.1.2017

FORWARD-LOOKING STATEMENTS Certain statements contained in this presentation other than historical facts may be considered forward-looking statements. Such statements include, in particular, statements about our plans, strategies, and prospects, and are subject to certain risks and uncertainties, including known and unknown risks, which could cause actual results to differ materially from those projected or anticipated. Therefore, such statements are not intended to be a guarantee of our performance in future periods. Such forward-looking statements can generally be identified by our use of forward-looking terminology such as "may," "will," "expect," "intend," "anticipate," "estimate," "believe," "continue," or other similar words. Readers are cautioned not to place undue reliance on these forward-looking statements. We make no representations or warranties (express or implied) about the accuracy of any such forward-looking statements contained in this presentation, and we do not intend to publicly update or revise any forward-looking statements, whether as a result of new information, future events, or otherwise. Any such forward-looking statements are subject to risks, uncertainties, and other factors and are based on a number of assumptions involving judgments with respect to, among other things, future economic, competitive, and market conditions, all of which are difficult or impossible to predict accurately. To the extent that our assumptions differ from actual conditions, our ability to accurately anticipate results expressed in such forward-looking statements, including our ability to generate positive cash flow from operations, make distributions to stockholders, and maintain the value of our real estate properties, may be significantly hindered. See Item 1A in the Company's most recently filed Annual Report on Form 10-K for the year ended December 31, 2016, for a discussion of some of the risks and uncertainties that could cause actual results to differ materially from those presented in our forward-looking statements. The risk factors described in our Annual Report are not the only ones we face but do represent those risks and uncertainties that we believe are material to us. Additional risks and uncertainties not currently known to us or that we currently deem immaterial may also harm our business. For additional information, please reference the supplemental report furnished by the Company as Exhibit 99.2 to the Company Form 8-K furnished with the Securities and Exchange Commission in April, 2017.

When evaluating the Company’s performance and capital resources, management considers the financial impact of investments held directly and through unconsolidated joint ventures. This presentation includes financial and operational information for our wholly-owned investments and our proportional interest in unconsolidated investments. We do not control the Market Square Joint Venture and recognize that proportional financial data may not accurately depict all of the legal and economic implications of our interest in this joint venture. Unless otherwise noted, all data herein is as of March 31, 2017, and pro forma for the planned return of 263 Shuman Boulevard to the lender. 2
