Several "Mad Men" stars are nearing new contracts to remain on the AMC show, with January Jones, Elisabeth Moss and Vincent Kartheiser slated to receive significant salary increases, reports Deadline.com. Two of the three deals may already be done, the story reports.

Jones, Moss and Kartheiser will receive "well into six figures per episode," with the three actors close to agreements that would keep them on the show for two more season, the show’s sixth and seventh, the story notes.

Christina Hendricks may also receive a similar raise, although her deal is still being worked out, according to the article.

Lionsgate TV is preparing to start production on the show’s sixth season in October. Jon Hamm, who plays Don Draper, last year signed a three-year, eight-figure deal that will keep him on the show through the seventh and most likely final season of the drama, the story adds.
