 WHEREAS, in entering into the SPA and each purchasing their respective Shares for $525,000, the Shareholders relied on the representations regarding the debt free status of Watermark and that Watermark was negotiating an exclusive license agreement for the right to sell proprietary molecular diagnostic tests for the Zika virus and certain other mosquito borne illnesses (“Zika License”) and that the Zika License would remain in effect;  

 WHEREAS, during the month of January 2017, the Shareholders became aware that a Promissory Note dated November 1, 2011, amended and modified on December 11, 2014, July 7, 2015 and December 11, 2015, owned by P&G Holdings LLC (the “Note”) was allegedly still outstanding as of the Effective Date;  

 WHEREAS, the Zika License has been terminated and the licensor has terminated its ownership and involvement with Watermark; 

NOW, THEREFORE, in consideration of the foregoing recitals and the covenants herein, the parties hereto agree to rescind the SPA in its entirety, effective as of inception of such agreement, and further agree as follows:

1. Rescission of the SPA.
