6 Our Mission Develop, validate and deliver innovative diagnostic services that enable better patient - care decisions

7 What is Multiple Myeloma? Multiple Myeloma (MM) is a cancer of the patient’s plasma cells Plasma cells (PC) are found in the bone marrow PC normally make antibodies that help fight infections Symptoms include fatigue, hypercalcemia, renal failure, bone damage and fractures S econd most prevalent blood cancer 22,350 new diagnoses in 2013 in U.S. 77,600 patients in the U.S. living with MM T umors are molecularly highly heterogeneous making the disease difficult to treat C onsidered incurable – 5 - year survival from diagnosis is 43% Deadliest blood cancer, responsible for 2% of all annual cancer deaths in the U.S. More people die from MM than from melanoma; the deadliest form of skin cancer 2013 NCI Statistics: http:// seer.cancer.gov/statfacts/html/mulmy.html 2003 - 2009 NCI Statistics: http://seer.cancer.gov/faststats

8 MM Pre - cursor Condition - AMG Figure recreated from Dispenzieri, Blood. 2014; 123(1) pg. 4 MM is preceded by a more common, clinically asymptomatic precursor phase Asymptomatic monoclonal gammopathy (AMG) Definition based upon degree of bone marrow infiltration by malignant plasma cells Patients with AMG lack MM related end - organ/tissue injury Classified as monoclonal gammopathy of unknown significance (MGUS) or asymptomatic MM (AMM ) There are more than 3 million people in the U.S. >50 yrs. of age with MGUS Current techniques do not enable accurate identification of AMG patients that will convert to full - blown MM Risk of progression ranges from 1% to 10% per year Unmet clinical need for better models to predict progression Kyle et al, NEJM. 2006; 354(13) pg. 1362 - 1369 Dhodapkar et al, Blood. 2014; 123(1) pg. 78 - 85

9 MM – The Clinical Dilemma H ighly heterogeneous & deadly cancer ; prediction of a particular patient’s outcome is difficult for physicians Current treatment modalities vary from “watchful waiting” – to multi - drug regimens, stem - cell transplants and experimental protocols The selection of the best treatment is highly dependent on the risk assessment of each patient’s particular form of MM The classic staging tests include clinical factors, cell morphology, chemical markers, imaging studies and genetic abnormalities Experts agree that current prognostic methodologies lack ability to adequately predict the level of risk associated with each patient’s MM – low risk patients receive excessive treatment and high risk patients receive too little treatment Selection of the best course of therapy is challenging given status of conventional prognostic tests Fonseca et al, Sem. In Oncology. 2013; 40(5) pg.554 - 566

Proprietary Assay for Prognosis of Multiple Myeloma Patients 10 MyPRS ®

11 MyPRS ® Highlights A ccurately stratifies patients into more predictable risk categories and molecular disease subtypes Can prevent a low - risk patient from unnecessary , potentially toxic treatment and helps a high - risk patient consider an experimental protocol Precipitates a conversation with patients regarding prognosis Based upon 30 years of patient management and outcome experience from greater than 10,000 patients at University of Arkansas for Medical Sciences ( UAMS ) Analytical & clinical validity and clinical utility demonstrated in over 4,500 patients documented in peer - reviewed publications from 17 unique patient data sets from 4 countries Protected by 10 issued patents and 26 pending patent applications MyPRS® enables a more personalized risk - adapted therapeutic strategy for MM patients

12 MyPRS ® Enables Personalized Treatment for MM Patients Interrogates the expression levels of 70 important genes which stratify high - risk patients Predicts outcome in newly diagnosed patients and is a significant prognostic factor in predicting post - relapse survival Provides MM subtype classification via 700 gene signature to further stratify risk and aid in treatment selection Identifies common cytogenetic abnormalities by examining the expression of 816 genes – Virtual Karyotype Potential to take cost out of the system by minimizing unnecessary therapy and enabling truly personalized treatment options Probability of 5 - year event free survival: 77% Probability of 5 - year overall survival: 83% Probability of 3 - year overall survival: 62% LOW RISK HIGH RISK Probability of 5 - year event free survival: 34% Probability of 5 - year overall survival: 38% Probability of 3 - year overall survival: 17% Newly Diagnosed Patient: Post Relapse Patient: Shaughnessy et al, Blood. 2007; 109(6) pg. 2276 - 2284 Zhan et al, Blood. 2006; (108(6) pg. 2020 - 2028 Zhou et al, Blood. 2012; 119(21) pg. e148 - e150 Based on data accumulated at the University of Arkansas for Medical Sciences
