Under the auspices of His Excellency Ahmed Al Khatib, Chief Development & Delivery Officer Expo 2020 Dubai, and Trade and Investment Queensland Commissioner Middle East Ms. Donna Massie, OPENIA Chairman Mohammed Fadel Al Mazrooei and GMG CEO & Managing Director Craig Nicol signed the Letter of Intent - taking place simultaneously in the Australian Pavilion at EXPO 2020 DUBAI and the Trade and Investment Queensland office in Brisbane.

THERMAL-XR®~ powered by GMG Graphene is a coating system for restoring and improving energy efficiency to corroded or poorly performing refrigeration and air conditioning coils. The process coats, protects and rebuilds lost thermal conductivity by leveraging GMG's Graphene to increase the heat transfer rate, resulting in efficiency improvement, and reductions in both energy and Co2 emission for customers.

GMG CEO and Managing Director Craig Nicol stated, "The growing demand for cooling is impacting power generation and distribution capacity and is often one of the highest costs of a company's operation. GMG's THERMAL-XR® coating system is a high-tech but easy to apply solution to improve efficiency and save energy. The technology is a clear example of GMG's Graphene's ability to transfer heat, providing measurable efficiency gains for air conditioning asset owners. The Letter of Intent between GMG and OPENIA builds on the introduction by the Queensland Government's global business agency, Trade and Investment Queensland (TIQ), which has been very helpful. I am very pleased about reaching this milestone and very excited to see THERMAL-XR® penetrating the strategic Middle-East market".

OPENIA Chairman Mohammed Fadel Al Mazrooei said, "We are very pleased to progress our relationship with GMG in the UAE. The potential of this innovative product to bring both emission and energy savings to customers throughout the region aligns with our country's strategy for environment and sustainability. The importance of THERMAL-XR® and Clean-tech Graphene products in general to this part of the world is recognised today with the attendance of His Excellency Ahmed Al Khatib, and the Honorable Ms. Donna Massie here at the Australian Pavilion of EXPO 2020 DUBAI."

Trade and Investment Queensland Commissioner Middle East Ms. Donna Massie said, "GMG is an exceptional Queensland company with excellent values providing sustainable, innovative world-class energy saving and storage solutions. Trade and Investment Queensland are very pleased to support this LOI and to continue to assist and support GMG's growth and development in all Middle East markets."

GMG's Middle East and North Africa Representative Mounir Bouaziz added "This region has a big challenge when it comes to the energy costs to cool buildings. A simple solution such as Thermal-XR that can reduce energy costs has great potential here. The Letter of Intent provides a rapid pathway for mobilisation, operations, and future growth between GMG and OPENIA for the distribution of THERMAL-XR® within the United Arab Emirates".
