(1) If a lessee wrongfully rejects or revokes acceptance of goods or fails to make a payment when due or repudiates with respect to a part or the whole, then, with respect to any goods involved, and with respect to all of the goods if under an installment lease contract the value of the whole lease contract is substantially impaired (Section 2A–510), the lessee is in default under the lease contract and the lessor may:

1. (a) cancel the lease contract (Section 2A–505(1));
2. (b) proceed respecting goods not identified to the lease contract (Section 2A–524);
3. (c) withhold delivery of the goods and take possession of goods previously delivered (Section 2A–525);
4. (d) stop delivery of the goods by any bailee (Section 2A–526);
5. (e) dispose of the goods and recover damages (Section 2A–527), or retain the goods and recover damages (Section 2A–528), or in a proper case recover rent (Section 2A–529);
6. (f) exercise any other rights or pursue any other remedies provided in the lease contract.

(3) If a lessee is otherwise in default under a lease contract, the lessor may exercise the rights and pursue the remedies provided in the lease contract, which may include a right to cancel the lease. In addition, unless otherwise provided in the lease contract:

1. (a) if the default substantially impairs the value of the lease contract to the lessor, the lessor may exercise the rights and pursue the remedies provided in subsection (1) or (2); or
2. (b) if the default does not substantially impair the value of the lease contract to the lessor, the lessor may recover as provided in subsection (2).
