<p>The two men charged with planting electronic devices in a botched advertising scheme that created a bomb scare in the Boston area will have another day in court because plea agreement negotiations are continuing, a defense lawyer said Friday.</p><p>Peter Berdovsky, 27, and Sean Stevens, 28, have pleaded not guilty to placing a hoax device and disorderly conduct. They appeared Friday in Charlestown District Court. The case was continued to May 11.</p><p>"We're still talking," Michael Rich, an attorney for Stevens, said after the 5-minute hearing.</p><p>The battery-powered, light-up devices were part of guerrilla advertising campaign by Atlanta-based Turner Broadcasting Systems, a division of Time Warner Inc., to promote the Cartoon Network show "Aqua Teen Hunger Force."</p><p>Prosecutors earlier this month told the court they hoped to have the case resolved by Friday through a plea agreement. Assistant Attorney General Renee Dupuis declined to comment Friday on the negotiations.</p><p>The contraptions, featuring a cartoon character making an obscene gesture, were just illuminated circuit boards with batteries and wires.</p><p>The first of about three dozen of the devices put up in and around Boston was discovered by police on Jan. 31 attached to a bridge support beneath Interstate 93 and next to a subway station.</p><p>It sparked terrorist fears and prompted the deployment of the bomb squad, forcing the shut down of highways and bridges.</p><p>Turner Broadcasting and the advertising agency that carried out the campaign, Interference Inc., have agreed to pay a $2 million settlement to cover costs and restitution for the law enforcement response.</p><p>The head of the Cartoon Network resigned nine days after the stunt.</p><p>The signs were placed in nine other cities around the United States, but only in Boston did they elicit such a response.</p><p>The defendants, like their most recent appearance, were composed and respectful during the brief hearing Friday. During their first appearance they giggled and waved to friends. They are free on bond.</p><p>Stevens said to a friend in court before the hearing: "Welcome to the bench of doom."</p>
