Ordered that the order is affirmed, without costs or disbursements.
The Supreme Court did not improvidently exercise its discretion in conditionally granting the plaintiff's motion to vacate her default in serving a bill of particulars and in denying the defendant's cross motion for summary judgment. The plaintiff had a reasonable excuse for her failure to supply the bill of particulars demanded by the defendant, and also had a meritorious cause of action (see, Gutenplan v Dauman, 154 A.D.2d 337). Rosenblatt, J.P., Ritter, Pizzuto and Santucci, JJ., concur.
