I still believe the original Agreement remains because of one line in the Amended Agreement as follows (bolded)

From the Amended Alliacense Services Agreement

d. On or about July 7, 2012, PDS, TPL, Patriot and Alliacense entered into new agreements under which Alliacense took on a direct contractual relationship with PDS to pursue commercialization of the MMP and to provide litigation support to Agility IP law (“Agility”), hired to conduct MMP patent infringement litigation. The agreements executed at that time include the Alliacense Services Agreement dated July 7, 2012 ("Services Agreement"). Except as the Services Agreement is affected herein, those agreements are not changed by this Agreement.

Hope you are well. Been a long time my friend!
