Production of the First Cryo-Vacc™ Commence for DPD Laser RENERGEN LIMITED Incorporated in the Republic of South Africa (Registration number: 2014/195093/06) JSE Share Code: REN A2X Share Code: REN ISIN: ZAE000202610 LEI: 378900B1512179F35A69 Australian Business Number (ABN): 93 998 352 675 ASX Share code: RLT ("Renergen" or "the Company") PRODUCTION OF THE FIRST CRYO-VACC™ COMMENCE FOR DPD LASER Domestic natural gas and helium producer Renergen Limited ("Renergen” or the "Company") and DPD Laser (Limited) ("DPD Laser") have entered into an agreement for the manufacture and purchase of the first 110 Cryo-Vacc™ cases, following the launch of Renergen's Cryo- Vacc™ storage solution (see ASX announcement dated 15 February 2021). DPD Laser is one of South Africa's leading express courier companies that has been proudly serving South Africa for over 30 years. The key terms of the agreement with DPD Laser are: • The agreement relates to a fixed purchase of 110 Cryo-Vacc™ cases in a combination of all three sizes; and • The Cryo-Vacc™ cases will be delivered in May. There are no other material conditions to the agreement. Whilst the agreement with DPD Laser is not considered material to the Company from a revenue perspective, it represents a significant milestone for the Company regarding the commencement of manufacturing of the Cryo-Vacc™ to its customers. The agreement has been completed ahead of the launch of Phase 2 vaccination program for SA. Renergen has commenced construction of the 110 Cryo-Vacc™ cases for delivery to DPD Laser, which is expected to be completed by the end of May 2021. DPD Laser will offer the Cryo-Vacc™ cases to the market on a monthly rental arrangement, including the maintenance, delivery, and collection of the Cryo-Vacc™ cases from respective maintenance points. The three sizes offered currently include a large case (up to 2,400 vials), a medium case (up to 1,200 vials and a smaller case (up to 240 vials) which is ideal for smaller vaccination points such as pharmacies and medical practices. "This is an exciting time and another milestone for Renergen, and we look forward to working with DDP Laser in rolling out the Cryo-Vacc™. "The prototype was put through its paces in a first validation phase and was purely focused on temperature distribution and stability. Notably, the Cryo-Vacc™ passed successfully. We saw areas where we could improve the design during this process and resubmitted it for another round of validation yesterday. Many of the original components were replaced or improved upon. We do not anticipate updating the market with this validation, as it is merely a repeat of the previous validation using different components. "We believe the technology works, and as time progresses, we will continue to enhance and improve the Cryo-Vacc™ as we gain valuable data from people in the field using the product. The analogy we see here is that version 12 of a smartphone was not the first version released; they got there over time. Cryo-Vacc™ will continue to evolve, and this is the exciting part as it becomes more flexible and useful in the field, which is the goal," said Renergen CEO Stefano Marani. DPD Laser CEO Anton Visagie said, "We have the ideal solution, storage and distribution, given the current uncertainty on which vaccines will be used at various vaccination points across South Africa. Our technology can handle all three required temperatures of 2-8 degrees, -20 degrees and -70 degrees Celsius without being dependent on an external power supply for periods between 7 and 35 days."
