“I have long admired Dr. Kim as a global luminary and thought leader on the intersection of climate and public health, and we are incredibly fortunate to have him join Rainwater Tech’s post-combination Board,” said Mike Nefkens, Co-Founder and CEO of Rainwater Tech. “In addition to his exceptional experience and in-depth knowledge of global economic development and public health, he is a tremendously respected leader. With the addition of Dr. Kim to our Board, we are strengthening the work we have done to build a team with a keen understanding of the implications of public policy, macro-economic, regulatory and technology trends globally as we expeditiously advance commercialization of our rainfall generation technology.”

Jim Yong Kim, M.D., Ph.D., was the 12th President of the World Bank Group. Prior to being named World Bank Group President, Dr. Kim's career focused on health, education, and improving the lives of the poor. A physician and anthropologist, Dr. Kim previously served as the President of Dartmouth College and held professorships at Harvard Medical School and the Harvard School of Public Health. From 2003 to 2005, as director of the World Health Organization's HIV/AIDS department, he led the "3 by 5" initiative, the first-ever global goal for AIDS treatment, which helped to expand access to antiretroviral medication in developing countries. In 1987, Dr. Kim co-founded Partners In Health, a non-profit medical organization that now works in poor communities on four continents.

“I am honored to join the Rainwater Tech Board of Directors to help the company fulfill its mission of providing the world with reliable access to water,” said Dr. Kim. “Water sits at the intersection of social justice, public health, climate change, and economic development, and I am proud to leverage my experience and expertise in support of Rainwater Tech’s vision to solve one of humanity’s greatest challenges. I look forward to working alongside Mike and his team to enhance rainfall and mitigate drought conditions where it is needed most.”

Dr. Kim became World Bank Group President in July 2012. Soon after he assumed the position, the organization established two goals to guide its work: to end extreme poverty by 2030; and to boost shared prosperity, focusing on the bottom 40% of the population in developing countries. In September 2016, the World Bank Group Board unanimously reappointed Dr. Kim to a second five-year term as President.

During his first term, the World Bank Group supported the development priorities of countries at levels never seen outside a financial crisis and, with its partners, achieved two successive, record replenishments of the World Bank Group's fund for the poorest. The institution also launched several innovative financial instruments including facilities to address infrastructure needs, prevent pandemics, and help the millions of people forcibly displaced from their homes by climate shocks, conflict, and violence.

Dr. Kim has received a MacArthur "Genius" Fellowship, was recognized as one of America's "25 Best Leaders" by U.S. News & World Report, and was named one of TIME magazine's "100 Most Influential People in the World."

Additional risks related to dMY VI and Rainwater Tech include, among others:

• Rainwater Tech can provide no assurance of the effectiveness and success of ionization rainfall generation technology in increasing precipitation;
• Rainwater Tech has no operating history or revenues, which makes it difficult to forecast its future results of operations;
• The execution of Rainwater Tech’s business model, including technology or profitability of its products and services, is not yet proven;
• The rain generation industry is in its early stages and is volatile, and if it does not develop, if it develops slower than Rainwater Tech expects, if it develops in a manner that does not require use of Rainwater Tech’s services, if it encounters negative publicity or if Rainwater Tech’s solution does not drive commercial engagement, the growth of its business will be harmed;
• Rainwater Tech has not yet proven its ability to develop and implement new technologies, as well as the ability to obtain and maintain intellectual property protections for such technologies;
• A substantial portion of Rainwater Tech’s technology is derived from public-source intellectual property and as a result Rainwater Tech may face increased competition;
• Even if Rainwater Tech is successful in developing rainfall generation systems/technology and executing its strategy, other competitors in the industry may achieve technological breakthroughs which render Rainwater Tech’s technology obsolete or inferior to other products;
• If Rainwater Tech’s platform fails to provide a broad, proven advantage in rainfall generation, its business, financial condition and future prospects may be harmed;

• Rainwater Tech may be unable to successfully manufacture its products or scale up manufacturing of its products in sufficient quantity and quality, in a timely or cost-effective manner, or at all.

• Risks regarding potential changes in legislative and regulatory environments that may limit the scope of Rainwater Tech’s marketplace, including land restriction policies and its ability to obtain and maintain permits;
