DECISION ORDER
ORDERED that the judgment is affirmed, with one bill of costs to the respondents appearing separately and filing separate briefs.
The third-party defendant Evbo, Inc. (hereinafter Evbo), leased space in a building owned by the defendant third-party plaintiff Skyline Towers 5 and managed by the defendant third-party plaintiff Jonathan Woodner Co. In its leased space, Evbo owned and operated the Jack and Jill Nursery School. Evbo employed the plaintiff Yvette Sanford as a nursery school teacher. She was injured when a concrete platform at the top of an exterior "fire exit" staircase outside her classroom collapsed beneath her.
The Supreme Court correctly dismissed the third-party complaint against Evbo. The parties stipulated, in effect, that the trial judge would determine the issue of who was responsible under the lease for the maintenance and repair of the exterior fire staircase. The evidence was sufficient to support the conclusion of the Supreme Court that the defendants bore this responsibility. Moreover, any ambiguity in the lease was correctly resolved against the defendant lessor and its manager (see 455 Seventh Ave. v. Frederick Hussey Realty Corp., 295 N.Y. 166, 172). The evidence established that, throughout the period of the leasehold, the defendants' porters cleared the stairs of snow in the winter, arranged for outside contractors to paint the stairs and platform, and undertook repairs to the support beams under the platform that ultimately collapsed. The evidence also established that the defendants had inspected the staircase prior to the accident and found it to be rusty and corroded. Yet, the defendants did not warn the injured plaintiff or Evbo of the dangerous condition of the support structure. Thus, the defendants failed to establish a basis for liability against Evbo.
Furthermore, the broad indemnification provision in the lease was not limited to Evbo's acts or omissions. It failed to make an exception for the defendants' own negligence. Nor did it limit the defendants' recovery under Evbo's indemnification obligation to insurance proceeds. Accordingly, the indemnification clause is unenforceable under General Obligations Law § 5-321 (see Leone v. Leewood Serv. Sta., 212 A.D.2d 669, 672; citing Hogeland v. Sibley, Lindsay Curr Co., 42 N.Y.2d 153, 158-160; Jensen v. Chevron Corp., 160 A.D.2d 767; Graphic Arts Supply v. Raynor, 91 A.D.2d 827).
There is no merit to the defendants' contention that they were entitled to judgment as a matter of law as against the plaintiffs on the issue of negligence on the ground that the plaintiffs failed to establish proximate cause. The defendants failed to move pursuant to CPLR 4401 for judgment at the close of the evidence on the issue of negligence. Therefore, they not only failed to preserve their contention that they were entitled to judgment as a matter of law on the issue of proximate cause (see Hurley v. Cavitolo, 239 A.D.2d 559; Nelson v. Times Sq. Stores Corp., 110 A.D.2d 691), but they also implicitly conceded that this issue was for the trier of fact (see Torillo v. Command Bus Co., 206 A.D.2d 520, citing Miller v. Miller, 68 N.Y.2d 871, 873; Thompson v. City of New York, 60 N.Y.2d 948; Gutin v. Mascali Sons, 11 N.Y.2d 97; Segal v. McDaniel Ford, 201 A.D.2d 717).
Moreover, the evidence presented at trial did not so preponderate in favor of the defendants that the verdict was against the weight of the evidence. To the contrary, the verdict was based on a fair interpretation of that evidence (see Nicastro v. Park, 113 A.D.2d 129, 134; see also Torillo v. Command Bus Co., supra at 521).
The defendants' remaining contentions are either unpreserved for appellate review or are without merit.
