Examples of forward-looking statements include, but are not limited to, the approach we are taking to discover and develop novel therapeutics using synthetic biology; statements regarding the potential of our platform to develop therapeutics to address a wide range of diseases, including: metabolic diseases, inflammatory and immune disorders, and cancer; the future clinical development of Synthetic Biotic medicines; the potential of our technology to treat phenylketonuria and cancer; the expected timing of our anticipated clinical trial initiations and availability of clinical data; the benefit of orphan drug and fast track status; the adequacy of our capital to support our future operations and our ability to successfully initiate and complete clinical trials; the results of our collaborations; and the difficulty in predicting the time and cost of development of our product candidates. Actual results could differ materially from those contained in any forward-looking statement as a result of various factors, including, without limitation: the uncertainties inherent in the preclinical development process; our ability to protect our intellectual property rights; and legislative, regulatory, political and economic developments, as well as those risks identified under the heading "Risk Factors" in our filings with the SEC. The foregoing review of important factors that could cause actual events to differ from expectations should not be construed as exhaustive and should be read in conjunction with statements that are included herein and elsewhere, including the risk factors included in our quarterly report on Form 10-Q filed with the SEC on May 8, 2020, and in any subsequent filings we make with the SEC.

Why Diseases of Immune System Regulation
For Synthetic Biotic Medicines?
Cross-talk Between Bacteria and Immune System
Immune system has evolved to recognize bacteria
Bacteria have evolved mechanisms to control the immune response
Unmet Medical Need
Growing need for novel treatments for immunological diseases and cancer
Platform
Preclinical POC for both immune stimulation and immunoregulation
Can produce immune mediators (small molecules, peptides, human cytokines)
Unique Advantage of SYNB
Targeted efficacy and improved safety
Multiple effectors from single Tx strain delivered to site of disease
