CYRX.......re: warrants.
Warrants are usually issued to officers or directors as incentives.....they can also be issued to a lender as a "sweetener" to supplement interest payments. Generally, a warrant allows the purchase of a share of the company's common at a specific price during some future time range.
So, in our case, the warrants.....for SPNG shares..... might be issued to Pike by SPNG in return for some kind of investment/loan. And yes, such an arrangement would normally require SPNG to file an 8-K providing the basic terms of the agreement, with the agreement itself as an exhibit. As Risicare has already noted, "If they filed they would."
Obviously this is just an example of something that could happen and not necessarily something that I expect to happen.
