There are various warrants that are available to purchase and the 1.85 represents a particular class of warrants of which you can buy the stock at a price of 1.85 up until expiration date (if excercised).
Important Note: - There are several hoops to jump through upon warrant exercise for US residents. Please see specific details on Titan's website. It can be done, but it will take quite awhile to do and you will have to go through the transfer agent AND eventually have to remove what is referred to as a US legend in order to trade the actual stock. Easier to exercise the warrants if you are a Canadian resident, though.
* Chicken - you knew this was eventually coming...should have taken that loan out or borrowed funds from your neighbor. You really had plenty of time
