Comedy writer-producer Mike Sikowitz, executive producer on the CBS comedy Rules of Engagement, has inked a two-year overall deal with the series’ producer Sony Pictures Television. Under the seven-figure pact, which starts in June, Sikowitz will continue as an exec producer on Rules if the sitcom returns for a sixth season. He will also develop his own projects for the studio. Sikowitz, repped by ICM and attorney Michael Gendler, joined Rules in Season 3 as a co-executive producer and was promoted to executive producer in Season 4. His credits also include CBS’ The Class, Fox’s Grounded for Life and NBC’s Friends.
