Is a single, indivisible offer made to more than one plaintiff valid under section 998 of the California Civil Code?

In support of his argument, Rumbeck cites the general rule that a single, indivisible offer made to more than one plaintiff is not considered valid under section 998 because it would require the plaintiff offerees to agree to a division of the settlement proceeds or to an allocation of those proceeds to the various causes of action in issue. (Meissner v. Paulson (1989) 212 Cal.App.3d 785, 791 (Meissner) ["only an offer made to a single plaintiff, without need for allocation or acceptance by other plaintiffs, qualifies as a valid offer under section 998"].)
