 About OncoCyte Corporation
 
 OncoCyte is primarily focused on the development and commercialization       of novel, non-invasive liquid biopsy diagnostic tests for the early       detection of cancer to improve health outcomes through early diagnoses,       to reduce the cost of care through the avoidance of more costly       diagnostic procedures, including invasive biopsy and cystoscopic       procedures, and to improve the quality of life for cancer patients.
 
 While current biopsy tests use invasive surgical procedures to provide       tissue samples in order to determine if a tumor is benign or malignant,       OncoCyte is developing a next generation of diagnostic tests that will       be liquid biopsies using blood or urine samples. OncoCyte’s initial       liquid biopsy tests under development are intended to be confirmatory       diagnostics for detecting lung, bladder and breast cancer. OncoCyte’s       diagnostic tests are being developed using proprietary sets of genetic       and protein markers broadly expressed in numerous types of cancer.
