Terry O'Quinn has signed up for more episodes of Hawaii Five-0.

The former Lost star was originally contracted to appear in six episodes of the CBS drama's second season.

O'Quinn's role as Lt. Commander Joe White has now been expanded, executive producer Peter Lenkov told TV Guide.

"His original deal was six episodes, and now we'll do another three," he revealed. "And we're hoping for even more."

O'Quinn recently admitted that he is keen to reunite on-screen with Lost co-star Michael Emerson. He has also signed up for a role in Desperate Housewives creator Marc Cherry's new ABC pilot Hallelujah, which is currently undergoing re-writes.

"Terry's a guy who really wants to get his own show, and he deserves that," said Lenkov. "That's his goal. But we'd love to make it work where he could do both."

Hawaii Five-0 continues on Mondays at 10/9c on CBS.
