Manhattan prosecutors are planning to offer a deal to 340 Occupy Wall Street protesters that would dismiss the charges if they stay out of trouble for six months, a lawyer representing some of the demonstrators said yesterday.

The deal would apply only to those issued desk- appearance tickets — but exclude more than 300 others who were charged with a misdemeanor or issued a summons, said the lawyer, Martin Stolar, one of the National Lawyers Guild members volunteering to represent protesters ree of charge.

The DA could still offer a similar deal for those summons-holders.

But some OWS members vowed to nix any deal.

Lauren Digioia, 26, who was busted for disorderly conduct, said, “The police were wrong, their actions were unjust. If I have to go to court to fight this, I will.”
