ORDERED that the order is reversed insofar as appealed from, on the law, with costs, the cross motion is granted, and the complaint is dismissed.
CPLR 3216 provides a party confronted with a less than diligent adversary with a means to expedite the prosecution of the action by serving upon him or her a written demand that he or she file a note of issue within 90 days, or in the event of a default, risk dismissal of the action (see Carte v. Segall, 134 A.D.2d 397, 398; see also Papadopoulas v. R.B. Supply Corp., 152 A.D.2d 552). To avoid a default, a plaintiff served with a 90-day notice must comply either by timely filing a note of issue or moving for an extension of time within which to comply pursuant to CPLR 2004 (see Carte v. Segall, supra at 398; see also Papadopoulas v. R.B. Supply Corp., supra). Having failed to pursue either of the foregoing options, the plaintiff was obligated to demonstrate a reasonable excuse for the delay and a meritorious cause of action to avoid the sanction of dismissal (see CPLR 3216[e]; Flomenhaft v. Baron, 281 A.D.2d 389). The fact that the defendant may have been dilatory in responding to discovery demands does not constitute a reasonable excuse for the plaintiff's failure to respond to the 90-day notice (see Papadopoulas v. R.B. Supply Corp., supra at 553). In addition, the other excuses offered by the plaintiff are not reasonable. Therefore, the defendant's cross motion should have been granted.
