Team One Advertising, the El Segundo-based agency that creates advertising for Lexus, said it has withdrawn from the competition to handle the Hardee's fast food restaurant account. Team One Chief Executive Leonard Pearlstein called the decision not to compete for the business difficult, but said that the agency was busy with new work for Lexus, Toyota Motor's luxury division. Pearlstein had handled the Hardee's business at his own agency until last October, when he joined Team One. Hardee's put the account into review shortly thereafter. Team One, a unit of New York-based Saatchi & Saatchi Worldwide, has been handling the $60 million account in the interim. Hardee's is a unit of Anaheim-based CKE Enterprises.
