(OTC: RNER) (BULLETIN BOARD: RNER) ("the Company"), which recently changed its name from Gold Rock Resources Inc. has released their Letter to the shareholders to summarize the recent changes. "To our shareholders: I would like to update you with the latest development of the Company. On March 25, 2009, the Company and China RainEarth Technology Co. Ltd., a company organized and existing under the laws of the People's Republic of China ("China RainEarth"), entered into a Business Cooperation Agreement (the "Agreement") for a term of twenty years. The purpose of the Agreement is to jointly conduct Hollow Fiber Membrane Materials' application and manufacturing business in China. According to the Agreement, the Company will provide Advice and assistance relating to development of marketing and provision of consultancy services, particularly as related to the Business to China RainEarth. China RainEarth will retain the services and give 60% of its revenue after deduction of direct operating costs, expenses and taxes to the Company in consideration of the Company's services. The Company has changed name to RainEarth Inc. to better reflect its current business. The following questions and answers address briefly some questions you may have regarding these changes. Q: What does China RainEarth do for business? When did they establish? What are their services/products? A: China RainEarth was established in October, 2005 in Beijing, China. China RainEarth is a hi-tech enterprise which is dedicated to the research & development and application of fiber membrane technologies. Developed independently by China RainEarth, the techniques for manufacturing hollow fiber membranes and fiber drawing equipment broke through foreign (mainly German) technical monopoly, and gained supports from the Beijing Innovation Fund for Small and Medium Enterprises in 2007, along with the Beijing Municipal Science & Technology Commission and the Innovation Fund for the 1st Batch of Small and Medium Technical Enterprises in 2008, the fund was released from the Ministry of Science and Technology in China. Q: What is hollow fiber membrane technology? What is the application of such technology? A: Together with nanotechnology, superconductivity and among others, separation membrane technology is regarded as one of the top six industrial high technologies in the 21st century. Over 70% of the chemical industry is related to the separation membrane technology, which is also fundamental to biological technologies. Hollow fiber membranes, as a core component of special filtration absorbers, are widely used in blood purification, ascites reinfusion and water treatment, etc. Q: What is China RainEarth's product? What is the market for this product? A: China RainEarth initially chose the benchmark product blood dialyzer, which can best certify their product research & development and manufacturing advantages, as the market entry point, and then further entered ascites concentrator and water purification markets. Blood dialysis is an effective measure for patients with acute and chronic renal failure (uremia) to sustain their lives. In 2007, 7-8 million pieces of blood dialyzers were consumed in China. With the rapid social and economic development as well as improvement of healthcare services, 15 million pieces of blood dialyzers will be consumed in China by 2012 and the market size will hit around US$200 million. 70 million pieces of dialyzers are consumed each year in developing countries including Turkey, India, South Africa and Pakistan. Q: What is China RainEarth's advantage? What are China RainEarth's qualifications? A: With 8 years of research and development by the founders of China RainEarth, they have become the only company in China that has mastered chemical formula and technique of hollow fiber separation membranes as well as the design and development capabilities for production equipment of hollow fiber separation membranes. Currently their hollow fiber separation membrane has passed China Compulsory Certification and tests by the State Food and Drug Administration in China. Since China RainEarth has proprietary fiber membrane manufacturing techniques (only German Company: Fresenius can independently manufacture fiber membrane production equipment) and the capabilities to design and develop assembly and production lines, no need to import expensive equipment, therefore, the products will have strong cost advantage. Also, dialyzers manufactured by China RainEarth have undergone clinical experiments and CCC certification, and obtained registration certificates. China RainEarth has also completed all tests and clinical experiments necessary for CE certification, and is qualified to export its products. Q: What is China RainEarth's current production capacity? A: Currently China RainEarth can produce about 150,000 pieces of blood dialyzers annually from their own facility. China RainEarth may lease other facilities to expand the production capacity. Q: What is China RainEarth's development objective? Long term and Short term? A: Long-term Development Objective: China RainEarth will follow the success model of Fresenius in Germany, to become a one stop shop producer and service provider which include the entire industrial chain, and will enter the extensive market of various filtering absorbers through manufacturing hollow fibrous membrane products based on patented hollow fibrous membrane technology and the design and manufacturing technology of the membrane equipment. Short-term Development Objective: It will begin with the manufacturing technology of blood dialyzer and ascites concentrator, which is to the best of China RainEarth's power and there are sufficient profit margin and market capacity for these two products.
