5:46pm: The Bobcats have confirmed via press release that they're tendering a qualifying offer to Henderson.
12:31pm: The Bobcats will extend a qualifying offer to Gerald Henderson, making him a restricted free agent, reports Rick Bonnell of the Charlotte Observer (via Twitter). However, according to Bonnell, Byron Mullens won't receive a QO of his own from the Bobcats.
Both Henderson and Mullens met the starter criteria in Charlotte, meaning that their qualifying offers would have been worth $4,531,459 each. For Henderson, that's a modest increase on what would have been a $4,267,426 offer, but it represents a significant increase for Mullens, who otherwise would've been in line for a $3,293,976 QO. Perhaps that played a part in the Bobcats' decision, though Mullens' unproductive second half (7.2 PPG, 3.7 RPG in 20 games after the All-Star break) likely didn't help his case either.
When free agency opens next week, both Henderson and Mullens will be free to negotiate with any team, but only Mullens will be able to sign outright with a rival club. If Henderson signs a rival offer sheet, the Bobcats will have three days to match it.
