Unless the plaintiff's or plaintiffs' contributions to the partnership or the plaintiff's or plaintiffs' allocable share of partnership property amount to 5% or more of the contributions of or allocations to partnership property of all limited partners, in their status as limited partners, or unless the contributions of or the share allocable to the plaintiff or plaintiffs have a fair value in excess of twenty-five thousand dollars, the limited partnership in whose right such action is brought shall be entitled at any stage of the proceedings before final judgment to require the plaintiff or plaintiffs to give security for the reasonable expenses, including attorney's fees, which may be incurred by the limited partnership in connection with the action. The amount of this security shall be determined by the court.
