(AP) — A preliminary settlement of up to $4.5 million has been reached in a class-action lawsuit for people exposed to hepatitis A but not sickened during a Hawaii outbreak in 2016.

Seattle attorney Bill Marler announced the settlement Friday. A claim form must be submitted by Nov. 29. A final approval hearing will be held in December.

Those affected could receive $150 to $350, depending on their level of exposure.

Hawaii health officials identified raw scallops served at Genki Sushi restaurants on Oahu and Kauai as a likely source of the outbreak that infected nearly 300 people.

Numerous other lawsuits have been filed for those who got sick, including a woman who died.

Marler is handling more than 100 of those cases. He says all but a handful have settled.
