From the Yahoo Board  Bill answered my q

to answer the question about the partnership and when it will be finalized i asked bill if april 4 still was in the plan and not april 30th since PHOT and RXNB extended their date to april 30. and based on my response i believe april 4 will still seal the deal for us.. ill copy and paste my extremely long and thorough FB conversation with bill below..........

ME: ""does the extension to april 30 between PHOT and RXNB have anything to do with our closing date on the deal thats suppose to be april 4? i know we are separate, but to me it seems like a 3 way deal""
