The motion court correctly dismissed all causes of action to the extent they purported to assert fraud claims against any defendants on the ground that such purported fraud claims simply duplicated plaintiff's contract claims; a contract action may not be converted into one for fraud by the mere additional allegation that the contracting party did not intend to meet its contractual obligation (DePinto v. Ashley Scott, Inc., 222 A.D.2d 288). The motion court also correctly dismissed all claims against the individual defendants, who were shareholders, officers or employees of defendants Westbury Brooklyn and Café Concepts, since, inter alia, the relevant writings, on their face, purport to bind the entities only, and any claim that an individual orally agreed to guarantee the entities' obligations is barred by the Statute of Frauds (General Obligations Law § 5-701[a][2]). Although Westbury Brooklyn was incorrectly named in the original agreement engaging plaintiff to perform the work, plaintiff has admitted in its complaint and opposition affidavit the identity of the party with which it contracted.
We modify to dismiss as against Westbury Brooklyn the first, second and third causes of action, all based on the original September 1 997 agreement between plaintiff and Westbury Brooklyn, on the ground that plaintiff's claims against Westbury Brooklyn thereunder were discharged by the parties' subsequent July 1998 letter agreement that expressly "supercede[d] [sic] any previously agreed to terms and conditions related to the cost" of the project (see, Denburg v. Parker Chapin Flattau Klimpl, 82 N.Y.2d 375, 384; Mallad Constr. Corp. v. County Fed. Sav. Loan Assn., 32 N.Y.2d 285, 293; Sheehy v. Andreotti, 199 A.D.2d 148, 150). We affirm the motion court's denial of the motion to dismiss as to the seventh cause of action insofar as based on alleged breach of contract by Café Concepts, in that the August 1998 letter to plaintiff from Café Concepts, an entity related to Westbury Brooklyn, stating that "[w]e acknowledge that we owe you a balance of $300,000", is susceptible to interpretation as an assumption by Café Concepts of Westbury Brooklyn's obligations under the July 1998 letter agreement. The motion to dismiss was also correctly denied as to the eighth cause of action, for alleged diversion of Lien Law trust funds, since the amount of trust funds that existed is an issue of fact that cannot be determined on a motion addressed to the pleadings.
Finally, plaintiff's ninth cause of action, for unjust enrichment, was correctly dismissed on the ground that the parties' rights and obligations are defined by valid and enforceable written agreements (Clark-Fitzpatrick, Inc. v. Long Island R.R. Co., 70 N.Y.2d 382, 388). In view of the legal insufficiency of the unjust enrichment cause of action, the denial of the cross motion for leave to amend the complaint to name an additional defendant on that claim was also correct.
