Those warrants would disappear if the loan is paid off in five years, since they can't be exercised until 2018. At that point, the government will be able to buy more than 3 million Tesla shares for $7.54 each, and 5,100 additional shares for $8.94 apiece. While it can't exercise those warrants now, at the recent record high of $97.12, the warrants would net taxpayers a $277 million profit.
