A Newark, Calif.-based pharmaceutical company, Depomed, is relocating its headquarters to north suburban Lake Forest and bringing new jobs to the area. The company announced today it has signed a lease for its new corporate headquarters in the Landmark Conway Farms complex in Lake Forest. The same complex houses Abbott Nutrition and Horizon Pharma.
