—Order unanimously affirmed without costs. Memorandum: Supreme Court properly granted that part of plaintiffs motion seeking partial summary judgment determining that plaintiff had lawfully terminated a Sales Representative Agreement (Agreement). Pursuant to the Agreement, executed July 1, 1993, defendant was appointed as plaintiffs sales representative in the Midwest. Either party could terminate the Agreement effective at the end of a calendar month upon 60 days’ prior written notice. Commissions would be paid on any order placed before the effective termination date and shipped within 90 days after the effective termination date. Defendant contends that plaintiffs attempt to terminate the Agreement by letter dated November 20, 1996 was ineffective. We disagree. The Agreement was for an indefinite period of time and thus is presumed to constitute an at-will employment arrangement (see, Murphy v American Home Prods. Corp.,
The court also properly granted that part of plaintiffs motion seeking summary judgment dismissing the second and third counterclaims. There is no basis for recovery of commissions beyond those provided for in the Agreement. Defendant may not recover under a theory of unjust enrichment; the existence of a valid and enforceable written agreement precludes recovery on such a quasi-contract theory (see, Eagle Comtronics v Pico Prods.,
Finally, the court properly granted that part of plaintiffs motion for dismissal of the fourth counterclaim, seeking punitive damages for fraud and/or gross negligence. Defendant failed to allege the existence of a false representation, an essential element of a fraud claim (see, Edison Stone Corp. v 42nd St. Dev. Corp.,
