Greenbriar and Captiva Verde Wellness Corp. ("Captiva") have tentatively agreed on a settlement of the Sage Ranch option and joint venture agreement ("Option and Joint Venture Agreement"). Pursuant to the terms of the Option and Joint Venture Agreement, Captiva would earn a 50% net profits interest in Sage Ranch by:
