(CNN) The payment is $211 million less than he expected, but Dewayne Johnson said he'll take it.

After months of legal drama, the terminally ill cancer patient has agreed to a reduced award of about $78 million from the agrochemical giant Monsanto, a sharp decrease from a jury's $289 million verdict.

Still, Monsanto's parent company says it will appeal.

Johnson, a former school groundskeeper, won a monumental case against Monsanto, claiming the company's famous weed killer Roundup gave him terminal cancer.

In August, a San Francisco jury awarded Johnson $250 million in punitive damages -- to punish Monsanto -- and about $39 million in compensatory damages -- for Johnson's lost income, pain and suffering.
