At least Richard Hatch kept his clothes on for his latest tribal council.

The famously bare-butted original Survivor winner traded in his gone-native look for a dark pinstriped suit Tuesday as he was arraigned Tuesday on federal charges of tax evasion for not telling the IRS about his million-dollar TV prize and related earnings.

The 43-year-old Hatch was formally rung up in U.S. District Court in Rhode Island for failing to mention his $1 million Survivor jackpot and the $10,000 check he picked up for appearing on the August 2000 Survivor finale special. Both amounts should have been declared on his 2000 tax return, the feds say.

Hatch faces a separate charge of not reporting $321,139 earned from a Boston radio show on his 2001 return.

The stakes are much higher than those he faced on the CBS reality show. Hatch is trying to survive a potential 10-year prison sentence and $500,000 fine.

After hearing the charges Tuesday, Hatch forked over his passport and $50,000 to cover his bond and then left the courthouse without speaking to reporters.

Hatch has reportedly agreed to plead guilty to the two charges in exchange for a more favorable sentence. A spokesman for the U.S. Attorney's Office has declined to discuss a possible plea bargain. Even if Hatch struck a deal, it would be non-binding and his case could still go to trial.

Hatch's attorney had no immediate comment on the case. No word yet on when Hatch is due back before the judge.

Hatch, a corporate trainer and consultant by trade (he touts his "dynamic, direct and honest style" on his Website, RichHatch.com), has really milked his Survivor triumph in Borneo in 2000. After drawing up a conniving game plan still mimicked by reality-show contestants, Hatch came out of the show a multimedia star with a self-help book (101 Survival Secrets), speaking gigs, a David Letterman appearance, top billing on a Survivor-themed cruise and serving as a go-to commentator for subsequent Survivor installments. He also got to drop trou in last year's Survivor: All-Stars, but was voted off in the fifth episode--sparing him the chance to not declare another $1 million check.

His celebrity has not been without its pitfalls, though. Shortly after wrapping the original Survivor, Hatch was accused of roughing up his adopted son, then 9. The charges were subsequently dropped. Then in 2001, he was found guilty of assaulting a former boyfriend. The conviction was overturned in 2002.

And his latest escapades aren't earning him much sympathy from Survivor overlord Jeff Probst. While cohosting Live with Regis and Kelly last week, Probst said the cocky Hatch probably thought that if he could win Survivor, he could outwit, outlast and outplay the IRS.

"Good luck," Probst said.
