I don't think it is Johnson Controls'. They have H850XP HB-VOJ.
My research found that it appears that FLIGHT SERVICES GROUP INC manage N351TC. They manage (or used to) some FAA registered jets based outside USA, like GIII N15HE.
Now they are working with Gama, following Gama's acquisition of Privatair USA. Look here :

Looks like your aircraft in the charter fleet:
Gama Charters - Fleet
Aircraft was offered for sale in 2007 by Privatair.
