2A109 - Option to accelerate at will.

     § 2A109.  Option to accelerate at will.        (a)  General rule.--A term providing that one party or his     successor in interest may accelerate payment or performance or     require collateral or additional collateral "at will" or "when     he deems himself insecure" or in words of similar import must be     construed to mean that he has power to do so only if he in good     faith believes that the prospect of payment or performance is     impaired.        (b)  Burden of proof.--With respect to a consumer lease, the     burden of establishing good faith under subsection (a) is on the     party who exercised the power; otherwise, the burden of     establishing lack of good faith is on the party against whom the     power has been exercised.
