3. Rcrane is passionate about the positive impact ExoCores can have on the town of Washington Introduction Executive Summary Agenda Targeted presentation to discuss the mission of Rcrane and ExoCores: Intro to Rcrane – RCXX1 Railroad Apps Review of new RCXX3 – Building Apps Introduction to ExoCores Modular home discussion Benefits of Precast concrete Assembly plant partner • Rcrane is pleased to introduce you to our company and our ExoCore concrete building modules (“ExoCore”) • ExoCores are concrete building modules that will absolutely inspire the communities confidence providing maximum life safety to protect Washington’s citizens while also maximizing energy efficiencies • Rcrane, a leading provider of bridge renewal services to class 1 railroads, was the result of our 15 year history building concrete bridge spans and recognizing a need in the market for a superior crane technology to build longer, stronger precast concrete bridges • In parallel to our rail business, we have spent the last 4 years developing Rcrane ExoCores: • Leveraging our knowledge of precast concrete • Building RCXX3 – the enabling crane for erection of ExoCores • Building relationships with partners that share our passion for a home that delivers maximum life safety and energy efficiency while keeps costs of ownership in-line with traditional construction • We are currently working to bring ExoCores to the Washington market and are reviewing assembly locations within the town of Washington

4. RCXX1 is the safest, fastest, easiest way to replace bridge and track panels. Our class 1 railroad customers require highly technical and trusted competency Rcrane & RCXX1 - Serving Class 1 Railroads Patented Rail-Mounted Dual Gantry Crane – RCXX1 One Trip Renewal Description View Brief Video Link Rcrane Introduction Rcrane is a series of 10 rail cars that operate together seamlessly to complete bridge span change outs in one trip The center component, Rcrane, with dual 40 ton hoists, operates directly over the bridge being placed Rflats, 8 in total, each 89 feet in length with 75 ton capacity are used for material staging, transport, installation and removal Rmules,2 sets in total, traverse on Rflats in guide rails to transfer materials car to car and into and out of Rcrane Final car, C Deck, houses spare parts and components as well as an 80 kilowatt, 480 volt generator that powers the entire system

5. RCXX3 was designed to meet the needs of ExoCores – heavy lifting with extreme precision and stability Introducing RCXX3 Patented Dual Gantry Crane for ExoCore Construction

6. ExoCore will combine the efficiencies of modular construction with the life safety, sustainability, and reduced energy consumption of precast concrete Introducing “ExoCore” Aspiring to Construct Superior Buildings The ExoCore Story • ExoCore concrete building modules will combine the benefits of modular construction in an indoor environment together with the life safety and energy efficiency of precast concrete • ExoCore homes and commercial buildings will be highly customizable • Assembly of the home will take place right in Washington with hometown skilled labor

7. Building under controlled plant conditions shortens project construction time. Generally less costly than traditional stick construction Overview of Modular “Stick” Construction Modular Construction in Practice Modular Construction Review Strengths of Modular Construction • Materials are safely and securely stored indoors to prevent damage or deterioration from moisture • Construction of modular buildings can occur simultaneously with the site and foundation work, so projects can be completed 30% to 50% sooner • 60 - 90% of the construction is completed inside a factory, which mitigates the risk of weather delays • Generally cost less than traditional construction • The indoor construction environment reduces the risks of accidents and related liabilities for workers 60 - 90% of home finished in manufacturing plant Home is staged and prepared for shipment to construction site Shortcomings of Modular Construction • More limited design and customization abilities versus traditional stick housing • Perceived lack of strength and durability, albeit likely in disagreement with modular contractors • No meaningful improvement in energy efficiency or air tightness Assembly and any final/minimal finish work done on-site Cranes used to lift pieces from flatbed truck onto foundation for assembly

8. Significant benefits of precast concrete construction – but slightly more expensive than traditional stick construction Overview of Precast Concrete Wall and Floor Panels Precast Concrete in Practice Precast Concrete Results in Additional Benefits Energy Efficiency • Double wall, compromised of 2 layers of pre stressed concrete that surround factory installed insulation • Air tight with high R-value insulation (R-21 to R-49) • May incorporate radiant floor heating, high velocity cooling, geothermal systems and Low-E glass windows and doors Life Safety College dormitory and rec center Multifamily housing in Chicago • Protection from the forces of nature best achieved with concrete based systems • Precast concrete wall panels give highest degree of safety from fire, hurricane and tornado force winds • Select precast rated at up to F5 tornado (200 mph) Sustainability • Homes will last for centuries, not just decades and will require minimal maintenance • Recycled content within precast can reach as high as 40% • Higher R-values with lower lumber costs Custom home – precast outer walls. Interior construction done on site – more expensive than traditional home Custom home – precast outer walls. Interior construction done on site – more expensive than traditional home

9. Washington is the ideal location to introduce ExoCores to America Assembly Plant Partner Seeking a Washington Assembly Plant Select Washington Progress to Date • After 4 years development, Rcrane is moving swiftly to provide Washington its highly engineered ExoCore concrete building cores • Reception to ExoCores has been extremely positive in the Washington community thus far • Washington represents the ideal location for ExoCores • Extreme weather patterns increasing • Hometown pride and sense of community – people don’t want to relocate but desire safety for their families • Hot summers and cold winters will maximize the energy efficiency opportunities of ExoCores • Will help to rebuild the community with homes that will withstand nature and inspire confidence from the safety ExoCores provide • Currently speaking to potential partners to locate our assembly plant • Our mission in Washington is not to maximize profit • Provide life safety and energy efficiency, introduce ExoCores, provide skilled jobs to local community, inspire confidence to rebuild • Seeking a partner with vacant space to donate or provide at lowest possible cost • Flexible pay structure to allow for payments once cash flow positive, a humanitarian effort in which once breakeven will be profitable together
