Vosh is one of the leaders of the Lucian Alliance, a coalition of former smugglers and mercenaries who've banded together to take advantage of the power vacuum left by the demise of the Goa'uld.
Vosh has placed a bounty on Vala Mal Doran's head because she failed to see a deal through and the Lucian Alliance lost a case full of weapons grade refined naquadah in the process. This was the incident when Vala stole the Prometheus and Daniel Jackson thwarted the buyers' plans (8.12 "Prometheus Unbound"). Vosh wished to set an example of Vala, wanting her dead or alive and stating that "no one defies the Lucian Alliance." He entrusted the two Oranians who had botched the deal, Tenat and Jup, to actively seek Vala and her partner ("Hans Olo", Daniel's pirate persona). Tenat and Jup failed in capturing Daniel and Vala, losing their cargo ship in the process, but called in an Alliance fleet to their rescue. The cargo ship which Vala and Daniel acquired was enhanced with impressive evasive technology by its former owner and they made their escape from the fleet. Vosh most likely still has the desire to see Vala and her partner, as well as her new partners, Cam Mitchell, the bounty hunter, and his Jaffa partner (Teal'c), dead. (9.04 "The Ties That Bind")
