From The Stargate Omnipedia
Jasec's Jaffa contact within the former army of Arkad. Te'rak visited Earth to find a buyer for a cargo ship loaded with weapons-grade naquadah. Once Jasec found a buyer the plan was to split the bounty almost equally. SG-1, however, disrupted the transaction.
Jasec later claimed that Te'rak told him the cargo ship was rigged to explode if anyone attempted to move it -- but this proved to be false.
