Take note too that the $6.4mil is for a specified maximum number of scans per month. Having a look at their business model in the prospectus they appear to contract a minimum fixed price per month based on a maximum number of scans. If the business of the client grows over time and they start increasing their scans per month above the contracted maximum then IME's revenue from the contract will also increase.

So this contract may ultimately bring in more that $6.4mil if the number of scans increases over the years.
