Gene Editing Notes: Shipping means that traits are being transferred to customers in a customer’s elite germplasm

Breeding is How Seed Co’s Develop Traits The Seed Industry: Productivity Traits are the Primary Basis for Competition. Seed Co’s Charge Productivity Trait Fees for Productivity Gains from Traits. Conventional Trait Development (Breeding!) has Severe Scale & Speed Limitations 4

Cibus’ Trait Machine Changes the Scale & Speed High Throughput Gene Editing System. - Operates as an Extension of Conventional Breeding Trait Development in a Fraction of the Time and Cost of Conventional Breeding “Nature Identical” Traits Non-GMO Traits that are Cibus conventional breeding like. Bio-Mfg. Standards Pharma Standard Quality Control & Assurance. High Throughput Gene Editing System Timebound, Predictable & Reproducible Breeding System. RTDS 5

Trait Machine is a Step Change in Trait Development Transforms the Steps Involved in- 1) Trait Development, and 2) Commercialization! 1– Prototyping Runs: Accelerates Development & Proof of Concept 2– Production Runs: Accelerates Speed to Market. Trait Machine Once a trait is developed, Trait Machine directly Trait Machine accelerates accelerates prototyping or edits a customer’s time to commercialization. testing of different traits. elite germplasm. 6

Addresses the Pressing Need From Climate Change Billions of Acres being hit by Changing Diseases, Pests & Resources Desperate Need for Scale & Time Change in Trait Development Gene Editing is Virtually the Only Tool that Can Address Climate Challenges at Scale 7

Climate Need is Driving Regulatory Change Global Push: Regulate Gene Editing Like Conventional Breeding New Gene Editing Regulations in Place Positive Policy Processes Underway Positive Policy Discussions Note: Cibus traits are developed without integrating foreign DNA in the process or product. in key target markets including the United States, the new gene editing regulations are specifically separating Cibus traits from GMO (Genetically Modified Organisms) and regulating Cibus Traits similarly to traits from conventional breeding. 8

The Market Opportunity The Business, Product and Economic Opportunity of Plant Traits

Trait Products are a Royalty Business Traits are Genetic Characteristics that Enable Plants to Manage Environmental Challenges Royalties are Paid for: Improved Yields, Increased Productivity, and/or Lower Costs (Chemicals!) Trait Royalty Market - $$$ “Traits by Acres by Trait Fees”

Example: The “Bt” Trait Trait: A “Bt” Protein that is Engineered into a Plant to make it Toxic to Plant Specific Pests. Bt Trait Economics: kills pests, decreases pesticide use/cost, increases yields. Crop Pest Note: Slide 22 for term definitions, data sources & assumptions.. Annual Trait Fees $2.6 B $0.5 B $0.7 B (by Crop 2020 est.)

Business Model: Traditional Trait Distribution Model: Traits Distributed in Seeds by Seed Co’s Seed Co’s Pay Trait Royalties based on Trait Fees Paid by Farmer TURN TO WHO TURN TO Farmers Seed Companies Trait Developers Challenged by the impacts of Environment & Climate change Seed Co’s sell Farmer seeds with Develop Productivity Traits traits to address productivity needs. - License Trait IP to Seed Co’s. Farmers pay Seed Co’s trait fees Collect Royalties: (in total cost charged for seed) - Seed Co’s pay Trait Royalties for Trait IP based on Trait Fees. 12 12
