A motion for leave to amend a pleading should not be granted where prejudice or surprise to the opposing party results directly from the moving party's delay. The determination to permit or deny amendment is committed to the sound discretion of the trial court. In exercising its discretion, the court should consider how long the party seeking the amendment was aware of the facts upon which the motion is predicated and whether there is a reasonable excuse for the delay.
