The court properly granted defendant's cross motion for summary judgment. Plaintiff's failure to notify defendant for more than two years of the underlying occurrence, in which plaintiff's employee was injured in a construction site accident, constituted noncompliance with the condition precedent to coverage and vitiated the contract of insurance ( see Great Canal Realty Corp. v Seneca Ins. Co., Inc., 5 NY3d 742, 743). Plaintiff's claimed belief of nonliability, on the basis that its injured employee's exclusive remedy was under the Workers' Compensation Law, was not reasonable under the circumstances ( cf. Tester v Paramount Ins. Co., 220 AD2d 334 [1995]).
