Test of good faith for modifications.

- Effective use of bad faith to escape performance on original contract terms is barred, and extortion of "modification" without legitimate commercial reason is ineffective as a violation of duty of good faith. Fratelli Gardino v. Caribbean Lumber Co., 587 F.2d 204 (5th Cir. 1979).

Waiver of breach.

- One having accepted benefits arising under contract after being notified of anticipated breach, and not having given notice of intention to rely on its exact terms, but having continued to accept benefits thereunder, may not recover for such alleged breach or failure to perform fully order the complete terms of the original agreement. Acceptance of such benefits after notice of an alleged breach will constitute waiver of breach. B-Lee's Sales Co. v. Shelton, 141 Ga. App. 870, 234 S.E.2d 702 (1977).
