PIONEER: Proprietary AI Platform for the Rapid Discovery and Design of
Patient-Specific Neoepitopes used to Derive Immuno-Oncology Therapies

           T-cell                  Neoepitopes are ideal cancer immunotherapy targets that:

                                   •   arise from patient-specific tumor mutations;
                                   •   play a critical role in T-cell mediated antitumor immune response;
                                   •   are absent from normal tissues and;
                                   •   are recognized as non-self by the immune system.

                                   Our proprietary AI-platform PIONEER is trained to efficiently
                                   identify and select the best neoepitopes for de novo T cell

Key Advantages of Our PIONEER Platform

●   Identification of Therapeutic Neoepitopes: Better anti-tumor effect correlating with de
    novo T-cell activation

●   Identification of Therapeutic Patient-Specific Neoepitopes: Unique to each patient’s
    cancer based on HLA subtype

●   Identification of Multiple Neoepitopes: Increase therapeutic effect and overcome clonal
    heterogeneity and tumor immune escape issues

●   Speed: Identifies neoepitopes within 24 hours from receipt of patient biopsy sequencing
    data

●   World Wide Clinical Applicability: In accordance with GAMP5 and compliant with cGMP

●   Potential for Repeat Use of PIONEER Over the Lifetime of a Patient’s Cancer
    Treatment: Multiple, PIONEER-designed therapies targeting emerging cancer clones

●   Safety Profile: Deselects potentially harmful neoepitopes, limiting off target effects

●   Continuous Improvement: Incorporates ongoing data and new features to increase
    predictive power

Key Strengths of our EDEN Platform Enabling AI-Based Vaccine
Discovery and Design

●   Ability to Predict Protective Vaccine Antigens: Predicts protective vaccine antigens with great
    precision, potentially improving on the attrition rates for new vaccine product candidates

●   Identification of Novel and Unbiased Targets: Identifies underlying feature patterns enabling discovery
    of novel vaccine targets

●   Data Driven Precision: AI-based identification of novel targets and filters irrelevant proteins reducing
    burden on pre-clinical development

●   Ability to Provide Broad Protection: Leverages genomic sequencing data to identify targets or
    domains present in clinical strains

●   Extraordinary Sensitivity: EDEN is capable of identifying antigens included in marketed vaccines as
    well as novel, protective antigens

●   Speed: Completes antigen discovery in as little as 48 hours and identifies vaccine candidates in weeks

●   Scalability: Can be applied in the discovery of vaccine candidates in almost any bacterial infectious
    disease
