OPINION OF THE COURT
Trippe Manufacturing Co. (“Trippe”) appeals an order denying its motion for summary judgment and granting a motion by Niles Audio Corporation (“Niles”) to compel arbitration. Because a duty to arbitrate must be founded upon a cоntractual obligation, we reverse the order compelling arbitration with regard to claims asserted by Niles that are unrelated to obligations expressly assumed by Trippe through the Asset Purchase Agreement (“APA”) that enterеd into effect on August 29, 2001. To the extent that Trippe expressly assumed obligations under the APA, however, the order compelling arbitration is affirmed.
*531 I.
Niles manufactures and markets consumer audio equipment.' In early 1998, Niles enterеd into an Exclusive Distributor Agreement (“EDA”) with SL Waber, Inc. (“Waber”). Under the terms of the EDA, Waber was to manufacture surge protectors for Niles. Waber was also obligated to perform lifetime service support for the product,'tо provide a toll-free customer service phone line, and to handle claims under a connected equipment guarantee (“CEG”) covering damage to electronic equipment connected to the surge-protector. In addition, Waber covenanted to give Niles quarterly reports on service and warranty claims. Clause 12(f) of the EDA states, in part:
All disputes, claims, and controversies arising under this Agreement, or a breach thеreof, shall be resolved by arbitration through the American Arbitration Association in accordance with its rules and regulations.
According to Niles, there were several technical problems with the surge-protector and, after selling several thousand units, Niles cancelled all outstanding orders in early 2001.
Trippe, a manufacturer, Entered into the APA with Waber, effective August 29, 2001. Under the terms of the agreement, Trippe acquired several assets associated with Waber’s surge protector business, including Waber’s rights, to the Niles Audio Contract. APA 1.1(h); APA Schedule 1.1(h). In clause 1.3 of the APA, Trippe expressly assumed certain of Waber’s liabilities, including:
(d) All liabilities, undertakings and obligations for all prоduct warranty and connected equipment guarantees covering all prodúcts sold to customers of the Waber Business, regardless of whether the product was manufactured, assembled or sold prior to, on or aftеr the date of Closing.
(f) All liabilities and obligations of [Wa-ber] arising after [August 21, 2001] under each of the Material Contracts listed on Schedule 1.1 (h) of the Disclosure Schedule.
Under the terms of the agreement, Trippe disclaimed responsibility for any debt, obligation, or liability owed by Waber beyond those expressly assumed.
In late 2002, Niles filed a demand for arbitration naming, among others, Waber and Trippe. With regard to Trippe, Niles requested the following relief: (1) a declaratory judgment binding Trippe to the agreement between Niles and Waber, (2) an order enjoining Trippe from discontinuing customer service support, warranty repairs, fulfilling the CEG, or discontinuing reporting obligations to Niles as required by the EDA, (3) attorneys’ fees and costs, аnd (4)' money damages. Trippe filed the present motion seeking both a declaration that the EDA arbitration clause is not binding1 on Trippe and an order enjoining Niles from pursuing its claims against Trippe in the arbitration proceeding. Niles responded with a motion to compel arbitration. The District Court granted Niles’s motion, and this appeal followed.
In granting Niles’s motion to compel arbitration, the District Court did not distinguish between claims arising out of Triрpe’s warranty and CEG obligations and other liabilities arising out of the EDA; nor did the District Court distinguish claims according to whether they arose before or after the effective date of the APA.

We exercise plenary review оver the District Court’s decision to compel arbitration.

University,
This arbitrability dispute is connected with a transaction involving interstate commerce, and is thеrefore governed by the Federal Arbitration Act, 9 U.S.C. § 1
et seq.
(“The FAA”). The FAA instructs courts to refer to principles of applicable state law when determining the existence and scope of an agreement to arbitrate.

III.
A motion to compel arbitration calls for a two-step inquiry into (1) whether a valid agreement to аrbitrate exists and (2) whether the particular dispute falls within the scope of that agreement.
See PaineWebber, Inc. v. Hartmann,
Although Trippe is not a signatory to the EDA, the EDA arbitration clause may nevertheless be enforceable against it. There are five theories for binding nonsignatories to arbitration agreements: (1) incorporation by reference, (2) assumption, (3) agency, (4) veil-piercing/alter ego, and (5) estoppel.

A.
Under New York law, the assignee of rights under a bilateral contract is nоt bound to perform the assignor’s duties under the contract unless he expressly assumes that obligation.
Sillman v. Twentieth Century-Fox Film Corp.,
This conclusion is entirely consistent with the case on which Trippe principally relies, i.e.,
Gruntal & Co., Inc. v. Steinberg,
Because Trippe agreed to arbitrate disputes related to obligations expressly assumed by the APA, an order compelling arbitration is proper if Niles’s claims are within the scope of that agreement to arbitrate. The language of clause 12(f) of the EDA is very broad, encompassing “[a]ll disputes, claims, and controversies arising under this Agreement, or a breach thereof.All of Niles’s claims presented in its demand for arbitration fall within the scope of this clause. The limiting factor with regard to Trippe is not the scope of the arbitration clause, but the existence of the agreement. We therefore hold that the order compelling arbitration is correct with respect to any claim arising out of the EDA after August 21, 2001, and to all claims related to the warranty and CEG obligations.
B.
Niles argues that the entirety of Waber’s obligations under the EDA are binding on Trippe, including an unlimited duty to arbitrate. . In an effort to achieve this result, Niles invokes the theory of incorporation by reference, citing
Exchange Mut. Ins. Co. v. Haskell Co.,
C.
Niles argues that because Trippe embraced the EDA, Trippe should be equitably estoppеd from challenging the arbitration clause, citing
Bouriez,
IV.
We hold that Trippe must arbitrate claims arising out of the obligations expressly assumed in the APA, specifically, claims related to warranty and CEG obligations and all claims arising after August 21, 2001. To the extent that the District Court’s order conforms with this holding, it is affirmed. To the extent that the order compelling arbitration encompassed claims unrelated to warranty and CEG obligations that arose prior to August 21, 2001, it is reversed.
