When John Roth exercized his $140MM in NT options I believe there was a PR outlining why he sold simultaneously.
The reason being the option holder is taxed as of the exercize date. ie, the price (value) at the time the option is exercized! The recent downturn left many who had exercized at higher prices blindsided with unexpected tax bills!
In John's case he no doubt expected an eventual slide, as he was privy to NT's accounting "majic!"
If Dale and Hugh haven't sold they are either niave or expect a higher SP! As we're still early in the year with significant news forthecoming, I suspect it's the latter!

PS: gas prices in the Capital Region approx $0.10 lower than Alberta.
