RE:Air tight agreementAs of June 30, Ucore had not fulfilled it's obligations as specified by that press release.
"The completion of License Fee payments under the Company’s previously announced Licensing Agreement with IBC (see Ucore Press Release dated March 3, 2015) in the amount of USD$2.9 million is a condition precedent to the execution of the Option Agreement. As of the current date, Ucore has already completed payments totaling USD$1.9 million against that total, with USD$1 million remaining outstanding."
In a few days when Ucore files its financials, we'll find out whether that payment was made by Sept 30. If they haven't, perhaps they've made the payment in Oct or Nov.
