the apparent literal meaning of the holding in Division (1) (a) of Booker — for which there is no cited authority on point - that a right of first refusal that lacks a triggering term is not enforceable. See Booker, 248 Ga. App. at 642 (1) (a). The courts of this state have frequently been asked to determine whether a certain event triggered a right of first refusal in agreements in which the triggering term did not specifically address the circumstances that arose. See, e.g., Hornsby v. Holt, 257 Ga. 341, 343 (2) (359 SE2d 646) (1987) (finding that exercising a power of sale in a security deed constituted a trigger of a right of first refusal that was triggered by the property owner electing to sell). See also Hasty v. Health Svc. Centers, 258 Ga. 625, 626-627 (373 SE2d 356) (1988) (<HOLDING>); Schoenbaum Ltd. Co. v. Lenox Pines, LLC, 262
