        <ExplanationTxt>Breakthrough Energy maintains records including grant proposals and other information used to evaluate grantees, grant agreements, reports from grantees on their use of funds and project status, and follow-up information obtained while investigating any at-risk grants. Breakthrough Energy's selection process may vary, but in any event the organization will only make a grant upon a written determination that the recipient is a suitable grantee and the grant will further the organization's charitable purposes. If Breakthrough Energy receives information indicating that a diversion of grant funds has taken place, Breakthrough Energy will withhold any further funds and will investigate. If Breakthrough Energy determines that a diversion occurred, it will take appropriate steps to secure repayment and withhold future payments until it is satisfied future diversions won't occur and the grantee is taking appropriate precautions.</ExplanationTxt>

BREAKTHROUGH ENERGY'S SELECTION PROCESS MAY VARY, BUT IN ANY EVENT THE ORGANIZATION WILL ONLY MAKE A GRANT UPON A WRITTEN DETERMINATION THAT THE RECIPIENT IS A SUITABLE GRANTEE AND THE GRANT WILL FURTHER THE ORGANIZATION'S CHARITABLE PURPOSES. IF BREAKTHROUGH ENERGY RECEIVES INFORMATION INDICATING THAT A DIVERSION OF GRANT FUNDS HAS TAKEN PLACE, BREAKTHROUGH ENERGY WILL WITHHOLD ANY FURTHER FUNDS AND WILL INVESTIGATE. IF BREAKTHROUGH ENERGY DETERMINES THAT A DIVERSION OCCURRED, IT WILL TAKE APPROPRIATE STEPS TO SECURE REPAYMENT AND WITHHOLD FUTURE PAYMENTS UNTIL IT IS SATISFIED FUTURE DIVERSIONS WON'T OCCUR AND THE GRANTEE IS TAKING APPROPRIATE PRECAUTIONS.</ExplanationTxt>
