Unknowns The total price of the deal is 13.5 million
Initial installment is 1.5 million cash and 7 million in cash or shares, if shares ( at what value)
The remaining 5 million in two installments of cash or shares (again at what value and what is the time frame for the final two installments)
Looks like they didn't overpay, just don't know all of details yet, so real cost is unknown
