(a) Except as otherwise provided in this chapter, the lease agreement may include rights and remedies for default in addition to or in substitution for those provided by this chapter and may limit or alter the measure of damages recoverable under this chapter.
(b) Resort to a remedy provided under this chapter or in the lease agreement is optional unless the remedy is expressly agreed to be exclusive. If circumstances cause an exclusive or limited remedy to fail its essential purpose, or provision for an exclusive remedy is unconscionable, remedy may be had as provided by this chapter.
(c) Consequential damages may be liquidated under Section 2A.504 or otherwise be limited, altered, or excluded unless the limitation, alteration, or exclusion is unconscionable. Liquidation, limitation, alteration, or exclusion of consequential damages for injury to the person in the case of consumer goods is prima facie unconscionable, but liquidation, limitation, alteration, or exclusion of damages where the loss is commercial is not prima facie unconscionable.
(d) Rights and remedies on default by the lessor or the lessee with respect to an obligation or promise collateral or ancillary to the lease contract are not impaired by this chapter.
